Our company's contact conductor pins and sockets are made of beryllium copper QBe2.0 and brass. Beryllium copper material has better performance than general copper alloys in terms of conductivity, thermal conductivity, high temperature resistance and wear resistance. Good elasticity and long service life, beryllium copper is the best choice for the contact conductor of the connectors. Brass material has a higher price advantage, with good mechanical and wear resistance, making it more durable and less prone to damage.

And the contact conductor pins and sockets are treated with gold plating technology on the surface. Gold is the most corrosion-resistant precious metal second only to platinum. Even in harsh environments, it will not easily corrode, and the product can maintain good contact performance during use.

The conventional contact conductor always adopts a surface treatment process with a thickness of 8U gold, defense and medical products can increase the gold plating thickness requirements according to demand

It is inevitable for connectors to have water ingress during use, such as in outdoor, workshop, medical facilities, etc. Therefore, industrial waterproof connectors should be selected for the connectors used in these scenarios.

The waterproof technology of waterproof connectors mainly includes the following aspects:

1. Selection of sealing materials: Use sealing materials with good water resistance, such as silicone, fluororubber, etc. These materials have high aging resistance, heat resistance and weather resistance.

2. Design of sealing structure: The sealing structure should be as simple as possible to reduce the risk of water leakage in the sealing area. At the same time, different sealing structures need to be used for different application scenarios, such as O-ring seals, clamp seals, injection molded seals, etc.

3. Waterproof test: After the waterproof connector design is completed, Meiyadi will conduct a waterproof testing to verify the waterproof performance of the connector by simulating the actual water pressure, temperature and other conditions in the usage environment. Recording test results helps designers further optimize sealing structures and material selection.

4. Surface treatment: Apply waterproof coating or electroplating on the surface of waterproof connectors to improve their waterproof performance.

The Meiyadi waterproof series connectors can meet the protection level of IP65~68, suitable for harsh environments such as rain, underwater, and watertight vacuum equipment. On this basis, we can also provide protection upgrade services, which can meet the protection requirements of water depths of 2 meters, 10 meters and 30 meters.

Common connectors processing techniques include stamping, lathe machining, injection molding, die-casting, CNC machining (CNC) and electroplating.

Stamping technology involves extrusion, punching and stretching of metal or non-metallic materials through molds and stamping machinery to obtain the desired connectors shape and structure. Its advantages lie in high efficiency, low cost, fast production speed and suitability for mass production.

Lathe machining, using the cutting tools of a lathe to perform precision cutting on connectors. This technology is suitable for processing connectors with complex shapes and has the characteristics of high processing accuracy and good surface smoothness, which can meet the processing needs of high-precision connectors.

Injection molding technology is a processing method that injects melted plastic material into a mold and after high-pressure injection and cooling, forms connectors accessories. Injection molding technology has advantages such as fast molding, high production efficiency and smooth surface of products, making it suitable for large-scale production.

Die casting technology is a processing technique that uses molten metal materials injected into the mold and filled with high-pressure molds. The accessories processed by die casting have high density, high strength and smooth surface, making them suitable for producing high-strength connectors.

Numerical control machining (CNC) has gradually become the mainstream technology for connectors machining due to its high precision and strong flexibility. By controlling the machine tool through preset programs for precision machining of connectors, various complex structure connectors machining can be achieved to meet high production requirements.

Electroplating technology is a commonly used surface treatment method in connectors processing, which uses electrochemical methods to deposit a metal layer on the surface of the connectors to improve its corrosion resistance, conductivity and appearance glossiness.

Meiyadi selects appropriate processing techniques based on the specific requirements and production scale of connectors, which can improve the quality and performance of connectors and meet the needs of different customers.

Shenzhen Meiyadi Technology Co., Ltd. was established in 2007 and is a professional manufacturer of precision personalized electrical connectors. Since its establishment, the company has been committed to researching international advanced precision electrical connector technology.

The shielding function of connectors is crucial for ensuring the quality of signal transmission. If the shielding effect of the connectors is not good, it can lead to signal distortion, interference, loss and other problems, affecting the normal operation of the equipment.

The Meiyadi connectors isolates the signal line inside the connectors from external electromagnetic interference in the following ways to ensure stable and reliable signal transmission:

1. Metal casing, adding copper metal casing outside the connectors to eliminate external electromagnetic interference through conductivity, Thereby reducing the impact on internal signals;

2. Ground wire shielding, the ground wire is connected to the external ground to form a low impedance circuit, which can introduce external electromagnetic interference into the ground. At the same time, interference from the signal lines inside the connectors can be eliminated through grounding to ensure the stability of signal transmission;

3. Shielding structure design, the internal structure of the connectors is compact, there is good contact between various parts. A reasonable shielding structure can reduce the intrusion of electromagnetic waves and improve the reliability of signal transmission

360 ° shielding of EMC, protection against electromagnetic interference

The conventional connectors housing uses H59 copper alloy, zinc alloy, as well as engineering plastic materials such as nylon, PC, PBT, etc. It can still maintain its physical state in harsh environments such as high and low temperatures, protecting the internal components of the connectors, such as insulators and contact bodies, from corrosion and damage caused by the external climate environment. At the same time, it can withstand damage caused by external induced environments such as vibration and impact.

After processing the metal casing, electroplating is also required. A metal coating can be applied to the surface of the casing, including silver plating, gold plating, nickel plating, etc. But connectors have better electromagnetic shielding and corrosion resistance.

The electroplated protection of the Meiyadi connectors from the inside out resists 96H salt spray, making our connectors more durable.
