What are the pin design requirements for pogopin thimble connectors?Pin design requirements for pogopin thimble connectors:With the development of the market and the upgrading of product technology, more and more consumers are not only confined to multi-functionality, but also they are pursuing the fashionable appearance and small and thin profile. However, to manufacture and design such products is a great challenge for all electronic product engineers. Because of the structural design space and the standardization of connectors, it is difficult for engineers to make good choices to accomplish it. In addition, in terms of structural space usage, assembly cost, lifetime, sample lead time and cost, spring-loaded pins have obvious advantages. The main function of spring pins is to overcurrent, ranging from 20MA-10A. The diameter, height and plating requirements of the spring-loaded needles are strictly regulated. Spring-loaded needles require a smooth surface into a small round hemispherical. pogopin thimble connector needle design requirements. Beveled surface: In order to ensure that the needle in the work and the needle tube always maintain contact, the needle and the spring contact end cut into a beveled surface. This design concept ensures a low and stable contact impedance, which guarantees stable conduction of the product. The counterbore design is a good choice for small connector sizes to meet the customer's elasticity requirements. The length of the spring for this design can exceed the length of the barrel, and in the case of space constraints, the reverse drilled design can be used to obtain a stable spring stroke. The flat bottom of this design due to certain conditions on the structure of the needle and barrel will not be unable to contact, which will lead to the current can not go to the barrel, the barrel wall will follow the spring straight away, which will lead to resistance is too large to make the voltage arc down.
