Factors causing adverse effects of pogopin spring thimble

time:2020-12-02 Views:174

  Current electronic and electrical products tend to be refined, easy to install, and have a long service life. The pogopin spring thimble connector is small in size and has a retractable design, which can well meet the needs of electronic and electrical products at this stage, so pogopin springs The thimble connector has been loved by many connector manufacturers.

Factors causing adverse effects of pogopin spring thimble(图1)

  Pogopin spring thimble is a very simple part, but it has very high process requirements. If there is no good quality control and perfect manufacturing process level, it is very easy to lose power and pin, or the durability (lifetime) is too short The problem. Pogopin spring thimble technology is extremely delicate and complicated, and each link of lathe processing, electroplating, and assembly may bring serious hidden dangers.

  Lathe processing:

  It is best to use Japanese automatic lathe processing, so that the precision of the parts can be guaranteed within +/-0.01mm, but most of the factories now use cutting machines for processing, which cannot ensure accuracy. In addition, the surface finish processed by the lathe, especially the inner surface finish of the pogopin spring thimble needle tube is very critical. Most factories do not have surface roughness testing equipment and do not control this parameter at all.

  Electroplating process:

  The thickness of the coating has a huge impact on the cost composition. Generally, the gold plating of pogopin spring thimble is 16u", but most other brands are in 1~2u", which has a big gap. In addition, the quality of the gold plating in the hole has a great influence on the electrical properties (impedance) and mechanical properties of the pin.

  Process aspects of assembly:

  Poor assembly process will cause the needle tip to be skewed, the needle height difference is too large, the pin is stuck, the nozzle peeling and other serious situations.
