It has advanced and complete production equipment, testing equipment and testing equipment, and has established a unique quality assurance system in strict accordance with the requirements of the IS09001 quality assurance system to ensure that the production process of the products and the various quality tasks of the enterprise are completely under quality control.

The switch connector is also called a connector. Domestically, it is also called connector and socket, and generally refers to electrical connectors. That is a device that connects two active devices to transmit current or signal.

The male end and the female end can transmit information or current through a contact, which is also called a connector.

Benefits of switch connector

1. Improve the production process—connectors simplify the assembly process of electronic products. It also simplifies the mass production process;

2. Easy to repair—If an electronic component fails, the failed component can be quickly replaced when the connector is installed;

3. Easy to upgrade—With the advancement of technology, components can be updated when connectors are installed, and new and more complete components can be used to replace the old ones;

4. Improve design flexibility—Using connectors enables engineers to have greater flexibility when designing and integrating new products and when composing a system with components.

The basic performance of the switch connector

The basic performance of the switch connector can be divided into three categories: mechanical performance, electrical performance and environmental performance.

Another important mechanical property is the mechanical life of the connector. Mechanical life is actually a durability indicator, which is called mechanical operation in the national standard GB5095.

It takes one insertion and one extraction as a cycle, and whether the connector can normally complete its connection function (such as contact resistance value) after the specified insertion and extraction cycle is used as the judgment basis.

1. Mechanical performance As far as the connection function is concerned, the insertion and extraction force is an important mechanical performance.

Insertion and extraction forces are divided into insertion force and extraction force (extraction force is also called separation force), the requirements of the two are different. There are provisions for maximum insertion force and minimum separation force in the relevant standards, which shows that from the point of view of use, the insertion force should be small (there are low insertion force LIF and no insertion force ZIF structure), and if the separation force is too small, It will affect the reliability of the contact.

The insertion and extraction force and mechanical life of the switch connector are related to the contact structure (positive pressure), the coating quality of the contact part (the sliding friction coefficient) and the dimensional accuracy of the contact arrangement (alignment).

2. Electrical performance The main electrical performance of the switch connector includes contact resistance, insulation resistance and dielectric strength.

① Electrical connectors with high-quality contact resistance should have low and stable contact resistance. The contact resistance of the switch connector ranges from a few milliohms to tens of milliohms.

②Insulation resistance is a measure of the insulation performance between the contacts of electrical connectors and between the contacts and the shell, and its magnitude ranges from hundreds of megohms to thousands of megohms.

③ Dielectric strength, or withstand voltage, dielectric withstand voltage, is the ability to withstand the rated test voltage between the switch connector contacts or between the contacts and the shell.

④Other electrical properties. The electromagnetic interference leakage attenuation is to evaluate the electromagnetic interference shielding effect of the connector, and the electromagnetic interference leakage attenuation is to evaluate the electromagnetic interference shielding effect of the switch connector.

It is generally tested in the frequency range of 100MHz~10GHz. For radiofrequency coaxial switch connectors, there are also electrical indicators such as characteristic impedance, insertion loss, reflection coefficient, and voltage standing wave ratio (VSWR).

Due to the development of digital technology, in order to connect and transmit high-speed digital pulse signals, a new type of connector, namely high-speed signal connector, has appeared.

Accordingly, in terms of electrical performance, in addition to the characteristic impedance, some new electrical indicators have also appeared. Such as crosstalk (crosstalk), transmission delay (delay), time lag (skew) and so on.

3. Environmental performance Common environmental performance includes temperature resistance, humidity resistance, salt spray resistance, vibration and shock resistance.

①Temperature resistance At present, the maximum working temperature of connectors is 200℃ (except for a few high-temperature special connectors), and the lowest temperature is -65℃.

When the connector is working, the current generates heat at the contact point, which leads to a temperature rise. Therefore, it is generally believed that the working temperature should be equal to the sum of the ambient temperature and the temperature rise of the contact point.

In some specifications, the maximum temperature rise allowed by the connector under the rated operating current is clearly specified.

②The intrusion of moisture resistance will affect the insulation performance of the connection h and rust metal parts. Constant heat and humidity test conditions are relative humidity 90%~95% (according to product specifications, up to 98%), temperature +40±20℃, and the test time is according to product specifications, at least 96 hours.

The alternating damp heat test is more stringent.

③When the salt spray-resistant connector works in an environment containing moisture and salt, the surface treatment layer of its metal structural parts and contact parts may produce galvanic corrosion, which affects the physical and electrical properties of the connector.

In order to evaluate the ability of electrical connectors to withstand this environment, a salt spray test is specified.

It hangs the connector in a temperature-controlled test box and sprays it with compressed air with a specified concentration of sodium chloride solution to form a salt spray atmosphere.

The exposure time is specified by the product specification and is at least 48 hours.

④Vibration and shock Vibration and shock resistance are important properties of electrical connectors.

They are particularly important in special application environments such as aviation and aerospace, railway and road transportation.

It is used to test the robustness of the electrical connector’s mechanical structure and reliable electrical contact.

An important indicator of sex. There are clear regulations in the relevant test methods. In the shock test, the peak acceleration, duration and shock pulse waveform, as well as the interruption time of electrical continuity should be specified.

⑤Other environmental performance According to the requirements of use, other environmental performances of the electrical connector include airtightness (air leakage, liquid pressure), liquid immersion (resistance to specific liquids), low air pressure, etc.

The style in the picture is a switch connector with a 19mm metal button. We also have 12mm, 22mm, 25mm, 30mm and other connectors.

The metal button has an adapter switch harness that is more convenient to use. Customers can easily connect their terminal equipment, saving welding time and cost, simple and efficient, and the price is low.

The metal button switch and the matching adapter switch harness are switches that use buttons to push the transmission mechanism to make the moving contact and the static contact press or disconnect and realize the circuit switching.

It is a very small category among the many categories in the electrical industry. It is inconspicuous, with a wide range of series and applications in all walks of life. From my perspective, I will get to know the “elves” that can be seen everywhere but don’t care.

The first memory of the metal button switch and the adapter switch harness is that I took the train to connect to the boiling water, sometimes standing in line at the vehicle connection point, leaning on the door of the control room, attracted by the flashing indicator light, red…green…

When it comes to the color of the indicator light, it is not that we use whatever color we want to use. The country has strict standards for the color of the indicator light. Among them, GB2682-81 and IEC60073 (IEC International Electromechanical Commission abbreviation) are the colors. Regulations.

The metal button switch and the supporting adapter switch harness are a particularly magical part.

No matter where you are or on any device, you can see its existence. When we turn on the mobile phone, we press the power button, and when we turn on the TV, we press the remote control.

The buttons of the air conditioner, the button that activates when we are driving, etc., are things that we don’t care about but have always existed, but it’s this small inconspicuous button.

When it fails, the air conditioner fails in the hot summer. ; When going to the toilet, the button for flushing the toilet is broken; when taking the elevator, the button does not work properly, etc.

At that moment, the button switch attracted much attention. The thing that we didn’t care about became bright at this moment, and then we realized its importance.

At this moment we will say “the quality is really bad” and “what is this broken thing”. We agree that what matters most to a thing is not its value, not its style, but it’s quality.

The main structure of the metal button switch and the supporting adapter switch harness is composed of a button, a return spring, a contact and a shell.

It is generally made into a composite type, with a pair of normally closed contacts and a pair of normally open contacts, and even some products can pass through The series connection of the elements adds contacts. There is also a self-holding button, which can automatically maintain the closed position after pressing the button and can only be opened after the power is turned off.

What you need to pay attention to use is to pay attention to whether it is a DC circuit or an AC circuit. There is a big difference between the two circuits, and the rated power and voltage need to be determined.

Generally speaking, on different occasions, the models of the button switch and the matching adapter switch harness are different. The following are common in daily life and production. Waterproof, with a sealed shell, can prevent the intrusion of rainwater. The anticorrosive type can effectively prevent the intrusion of chemical corrosive gases, so it is mostly used in chemical plants.

Explosion-proof switches can be used in places containing explosive gas and dust, and are mostly suitable for places such as coal mines. The knob type is generally a panel-mounted type, and the operating contact needs to be rotated by hand to have two positions on and off. There is also an emergency type, which is mostly used in important emergency operations. There is a red protruding mushroom-shaped button on the shell, which can be pressed to cut off the power when necessary.

What is the quality of the metal button switch and the supporting adapter switch harness? The production specifications require strict compliance with the requirements of the People’s Republic of China Machinery Industry Standard JB/T3907-2008.

Product quality requirements must undergo safety certification, namely “CCC” certification. “CCC” certification is a certification issued by the China Quality Certification Center (CQC) to manufacturers of electrical equipment.

The company that obtains the certificate should comply with national standards. “CCC” certification is also correct Effective control measures for market sales are also a necessary pass for products to enter the market.

The metal button switch and the supporting adapter switch harness are just a tiny part of the switch, it is more used in the equipment of the industrial manufacturing industry. If you are interested in these adapter switch harnesses and metal button switches, please contact us directly.

22mm LED Metal Hand Buzzer Alarm Indicator Light Signal Lamp

22 MM Flash LED Alarm Indicator Light Signal Lamp Flash Metal Hand Buzzer DC12V DC24V AC 220V Intermittent Sound

 

(1) Introduction of metal buzzer

 

1. The role of a metal hand buzzer is an integrated structure of an electronic buzzer, using DC voltage power supply, widely used in computers, printers, copiers, alarms, electronic toys, automotive electronic equipment, telephones, timers used as a sounding device in electronic products.

2 Classification of metal hand buzzer is mainly divided into two types: piezoelectric metal hand buzzer and electromagnetic metal buzzer.

3. The circuit graphic symbol of metal hand buzzer in the circuit with letters “or “HAT old standard with “FMLB” JD” etc.) said.

(2) Structural principle of metal buzzer

 

1. Piezoelectric metal buzzer is mainly composed of the multivibrator, piezoelectric buzzer, impedance matcher, resonance box, shell and so on. Some piezoelectric metal hand buzzer shells are also equipped with light-emitting diodes.

The multivibrator is composed of transistors or integrated circuits. When the power is turned on (1.5~15V DC working voltage), the multivibrator starts to vibrate and outputs 1.5~25kHz audio signals, and the impedance matcher drives the piezoelectric buzzer to sound.

The piezoelectric buzzer is made of lead zirconate titanate or lead magnesium niobate piezoelectric ceramic material. Silver electrodes are plated on both sides of the ceramic sheet, and after polarization and aging treatment, they are then glued together with the brass sheet or the stainless steel sheet.

2. Electromagnetic metal hand buzzer The electromagnetic metal hand buzzer is composed of the oscillator, an electromagnetic coil, magnet, vibrating diaphragm, and shell.

After the power is turned on, the audio signal current generated by the oscillator passes through the electromagnetic coil, causing the electromagnetic coil to generate a magnetic field. The vibrating diaphragm periodically vibrates and produces sound under the interaction of the electromagnetic coil and the magnet.

How does the conventional electromagnetic metal hand buzzer product work?

The working principle of the passive electromagnetic metal hand buzzer is: the AC signal generates an alternating magnetic flux on the core column of the support through the wire wrapped around the support. The alternating magnetic flux and the constant magnetic flux of the magnetic ring are superimposed to make the molybdenum The sheet vibrates at a given frequency of the AC signal and cooperates with the resonant cavity to produce sound.

The response curve and gap value of the entire frequency and sound pressure of the product, the natural vibration frequency of the molybdenum sheet (which can be roughly refracted to the thickness of the small molybdenum sheet), the frequency of the shell (Helmholtz resonance acoustic cavity), and the magnetic enameled wire of the magnetic ring The wire diameter is directly related.

(3) How do conventional piezoelectric metal buzzer products work?

 

The piezoelectric buzzer is a piezoelectric ceramic sheet that has been subjected to high-voltage extreme pressure and is pasted on a vibrating metal sheet. When an AC voltage is added, it will generate mechanical deformation and contraction due to the piezoelectric effect, and use this feature to make the metal sheet vibrate and make a sound

1. Peripheral support method-fix the outer diameter edge of the buzzer in the resonant cavity, generally a non-feedback buzzer, and the buzzer must be matched with the resonant cavity frequency to have a higher sound pressure output, And an external oscillator circuit generates a push signal to make the metal hand buzzer sound.

Node support method-fix the buzzer sheet in a ring structure approximately the same size as the diameter of the ceramic sheet. If the resonant cavity is properly designed, combined with a feedback buzzer with the correct frequency and a positive feedback circuit, larger sound pressure and correct frequency can be generated.

(4) What materials are made of conventional piezoelectric passive metal hand buzzer (external drive) products?

 

PCB fixed piezoelectric passive
Pogo pin piezoelectric passive metal buzzer

(5) What is the difference between an active metal hand buzzer and a passive metal hand buzzer?

The fundamental difference between an active metal hand buzzer and a passive metal hand buzzer is that the product has different requirements for input signals;

The ideal signal for an active metal hand buzzer is direct current, usually marked as VDC, VDD, etc. Because there is a simple oscillating circuit inside the metal hand buzzer, it can convert a constant direct current into a pulse signal of a certain frequency, and the alternating magnetic field is generated from the surface, which drives the molybdenum sheet to vibrate and pronounce.

However, some active metal hand buzzers can also work under a specific AC signal, but the voltage and frequency of the AC signal are very demanding, and this working method is generally not used.

The passive metal buzzer has no internal driving circuit. Some companies and factories call it a buzzer, and it is called a buzzer in the national standard.

Ideal signal square wave for passive metal hand buzzer work. If the metal hand buzzer is not responding to the pre-DC signal, because the magnetic circuit is constant, the molybdenum sheet cannot vibrate and sound.

(6) How to connect the electromagnetic passive metal hand buzzer and piezoelectric passive metal hand buzzer to the IC output pins in the electronic circuit?

The electromagnetic passive buzzer is an inductive load device, and the ideal input is a forward square wave, usually denoted as VO-P. Usually, the wiring circuit is as follows:

The passive buzzer is a capacitive load device, and the ideal input is a two-way square wave, usually denoted as VP-P. Usually, the wiring circuit is as follows:

But if the IC is an inverter 4049, etc., it is also ideal to connect the input and output of a NOT gate to a metal hand buzzer, but sometimes the output power of the IC is too small and the sound cannot meet the expected requirements.

If the metal hand buzzer is used for high sound pressure alarms, ordinary two-pin inductors cannot meet the requirements. Generally, three-pin tapped inductors are generally used with a boost ratio of 10 times. Some high sound pressures above 110dB may need to be used. The power transformer realizes the step-up.

(7) Production of metal hand buzzer

(1) Preparation of electromagnet M: Wind 100 turns of wire on an iron bolt about 6 cm in length, leaving 5 cm at the end of the wire as a lead, and stick the coil with transparent tape to prevent the coil from loosening, and then stick it with tape On a box, the electromagnet is ready.

(2) Preparation of shrapnel P: Cut a long iron piece with a width of about 2 cm from the iron can bend it at a right angle, connect a lead of the electromagnet to the shrapnel, and then use tape to stick the shrapnel on the wooden board.

(3) Use a paperclip as the contact Q, use a book to put the paperclip up high, glue it firmly with tape, and draw out a wire, as shown in the figure, to connect the circuit.

(4) Adjust the distance between M and P (by moving the box), so that the electromagnet can attract the shrapnel, adjust the distance between the contact and the shrapnel so that they can just touch, and you can hear the buzzing sound after power on.

19MM Metal Buzzer Loud Flash Sound Explosion-Proof Buzzer

19 MM Metal Buzzer 220v24v Loud 12v Flash Intermittent Sound Waterproof Explosion-Proof Buzzer

 

Hello everyone, it is a great honor to introduce our company again.

Our name is Yueqing Yulin Electronics Co., Ltd., and our company is an innovative industrial and trade company integrating R&D, production and sales.

The company was established in 1998 and has a history of 21 years. Now the company has three factories and a trading company.

Our company mainly produces indicator lights, metal button switches, rocker switches, guitar switches, touch system switches, waterproof micro switches and other products.

Our company is one of the most complete indicator light manufacturing companies in the world, and the only mainland manufacturer in China with UL metal button certification.

Our company is the founder of wire and metal buttons, as well as the creator of waterproof high-current rocker switches.

Below, our company briefly introduces a 19 mm metal buzzer 220v24v loud 12v flash intermittent sound waterproof explosion-proof buzzer product.

The buzzer is an electronic buzzer with an integrated structure. It is powered by DC voltage and is widely used as a sound device in electronic products such as computers, printers, copiers, alarms, electronic toys, automotive electronic equipment, telephones, timers, etc…

Buzzers are mainly divided into two types: piezoelectric buzzer and electromagnetic buzzer.

The buzzer is an integrated structure of an electronic buzzer, which belongs to a kind of electronic component.

Metal Buzzer Purpose/Function

It is a sounding device that can convert audio signals into sound signals. It is widely used in household appliances, in the alarm systems of banks and public security, and in electronic toys and game consoles.

It is mainly used for promoting or alarming. According to different designs and uses, it can emit various sounds such as music, siren, buzzer, alarm, and electric bell.

The buzzer used in the washing machine often buzzes to remind the user of the operation process.

Most of the buzzers used in burning appliances emit alarm sounds to warn users that the burning appliances are burning dry. As the doorbell application, the buzzer often emits “ding dong” or music to remind guests to visit.

The buzzers installed in the police, bank, and home guard areas often sounded. If someone enters the guard area, under the action of sensor control, the buzzer will sound the alarm.

Buzzers used in factories and schools often emit electric bells.

Metal Buzzer drive mode

Since the self-excited buzzer is driven by a DC voltage, it does not need to be driven by an AC signal. You only need to output the drive level to the drive port and amplify the drive current through a transistor to make the buzzer sound. It’s very simple. The self-excited metal buzzer is explained.

Here, only the externally activated buzzer that must be driven by a 1/2duty square wave signal is described.

There are two ways for a single-chip microcomputer to drive a separately excited metal buzzer:

One is the direct drive of the PWM output port

The other is to use I/O to periodically flip the level to generate a driving waveform to drive the metal buzzer.

The direct drive of the PWM output port is to use the PWM output port itself to output a certain square wave to directly drive the buzzer.

There are several system registers in the software settings of the MCU to set the output of the PWM port. You can set the duty cycle, period, etc. After setting these registers to generate the frequency waveform that meets the requirements of the buzzer, just turn on the PWM Output, the PWM output port can output a square wave of the frequency. At this time, this waveform can be used to drive the buzzer.

For example, when driving a buzzer with a frequency of 2000 Hz, you can know that the period is 500 μs. In this way, you only need to set the PWM period to 500 μs and the duty cycle level to 250 μs to generate a square wave with a frequency of 2000 Hz. The square wave can use the triode to drive the metal buzzer.

However, it is a bit more troublesome to use I/O to periodically flip the level to generate the driving waveform. A timer must be used for timing. The waveform of the frequency that meets the requirements of the metal buzzer is generated by the timing flip of the level. This waveform can be used to drive the metal buzzer.

For example, for driving a 2500Hz buzzer, you can know that the period is 400μs, so you only need to drive the I/O port of the buzzer to flip the level every 200μs to generate a frequency of 2500Hz and a duty cycle of 1/2duty. The square wave can drive the metal buzzer by magnifying it through the triode.
