wholesale PCB Terminal Blocks

Due to the lack of aging during the elastic treatment, the hardness of the parts does not meet the requirements of the drawings, so the elasticity gradually relaxes after multiple insertions and withdrawals, and the contact pressure is significantly reduced, resulting in poor contact. According to incomplete statistics, an electronic computer, radar or an airplane has tens of thousands of wholesale PCB Terminal Blocks contacts. Electrical contact failed.

Taking the SMA connector as an example, the US military standard and the Chinese military standard stipulate its life to be 500 times. 2. c. According to our practice for more than ten years, the common main failure modes are as follows. Sometimes the nickel layer is found to be peeled, peeling, etc. Poor contact often leads to sometimes no signals, and sometimes good electrical performance. Pay close attention to design, processing and other links, and strive to improve the reliability of the connector.9800. Although the material is selected correctly, the process is unstable,

the elastic treatment of beryllium bronze does not reach the hardness value specified in the drawing, and the snap ring is inelastic, causing the nut to fall off. During the inspection, it was missed.1 Careful design lays the foundation for product reliability. Example: Sometimes the size and shape of the inner conductor of different cable connectors are exactly the same, but the hole size that matches the cable is slightly different.

The cable assembly was found to be pulled off after a period of use Phenomenon, immediately analyze the cause, suspend assembly, adjust the gap in time, redesign and process a new sleeve.4 Failure of the cable assembly Cable assembly is usually composed of two parts: a cable connector and a high-frequency cable. These special and rare failure factors will not be discussed in detail here. The pins and sockets have been used for too long and have been severely worn, which is also a common phenomenon.. When the pin and jack are connected again, they will not touch at all.
