Factors causing adverse effects of pogopin spring thimble

time:2020-12-02 Views:143

  Current electronic and electrical products are developing in the direction of refinement, ease of installation and 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, so pogopin spring thimble The connector is favored by many connector manufacturers.

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

  Although the pogopin spring thimble is a relatively simple part, it has very high requirements on the process. If there is no good quality control and perfect manufacturing level, it is very easy to lose power and get stuck or has a short durability (lifetime). The pogopin spring thimble technology is particularly delicate and complicated, and every link of lathe processing, electroplating, and assembly may have serious hidden dangers.

  1. Lathe processing:

  Using Japanese automatic lathe processing, this can ensure that the precision of the parts is within +/-0.01mm, but most of the factories now use the cutting machine for processing, which cannot ensure the accuracy. For the surface finish of the lathe, especially the inner surface finish of the pogopin spring thimble needle tube is very important. Most factories do not have surface roughness testing equipment and will not supervise this parameter at all.

  2. The electroplating process:

  The thickness of the coating has a huge impact on the cost composition. The gold plating of Wanchang's pogopin spring thimble is 16u", but most other brands are 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.

  3. Assembling process:

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