The term "durable" may be understood differently by different people, but "durable" connectors typically include the following features:
Mechanical performance and electrical integrity are maintained after exposure to harsh environments and multiple coordinated operations;
Capable of withstanding high mechanical shock and vibration without affecting interconnect performance;
It can provide good EMI shielding characteristics in complex electromagnetic environments.
In order to improve durability, modern connector products are usually optimized through the following aspects:
Contact
Mainly focusing on the contact material, plating layer, and structure, optimization has been carried out in terms of reducing contact resistance, increasing contact area, enhancing the normal force of the fit, reducing environmental exposure, and reducing mechanical strength degradation after contact and repeated mating.
Insulator
On the one hand, the insulation material must meet the requirements of the design specifications. On the other hand, the entire insulation structure must also form a comprehensive protection for the contacts to avoid the impact of external factors on the contacts.
Locking and Termination
Additional latch mechanisms help paired connectors cope with higher mechanical shocks and vibrations. At the same time, in terms of termination with PCBs, fastening methods such as screws, welding, and soldering nails are also provided to meet high durability. Stability.
Sealing and shielding
For connectors that need to be waterproof, dustproof, and electromagnetic interference resistant, professional seals and shielding layers are naturally essential.
