Notes on selection of spring antenna thimble connector

　　With the gradual rise of smart wear, mobile phones are becoming more and more thin. Rapid charging promotes the sharp increase in the demand for high current connectors, which makes the spring antenna thimble connector more frequently used. Almost all intelligent digital products in the market need spring antenna thimble connectors. Only some low-end products may still use spring type connectors. What should be paid attention to in the selection of spring antenna thimble connector?

　　1、 Working stroke selection of spring antenna thimble connector: the selection of spring antenna thimble connector must be determined according to the space of the product used, and the one within the working stroke range shall be selected; If the space is too small, the spring of spring antenna thimble connector will be over compressed, which will affect the service life. If the space is too large, the contact may not be in place, and the impedance will be unstable and instantaneous break;

　　2、 Selection of electroplating materials: electroplating materials in spring antenna thimble connector will increase conductivity, prevent oxidation, anti-wear and other effects. Different materials have different functions. For example, gold has good conductivity. For high current connectors, products with high impedance requirements will usually choose electroplating gold;

　　3、 What are the effects of electroplating film thickness: Spring antenna thimble connector will produce certain friction due to contact when working, and wear will occur after a long time. The thickness of Electrodeposited film will affect the service life of the product. When it is used to a certain extent, the electroplated coating will be worn off, and the resistance may be too large and the impedance is unstable. The electroplating layer of spring antenna thimble with 100000 times is thicker than that with 10000 times. Therefore, the electroplating requirements must be selected according to the requirements when selecting the products;

　　4、 Influence of elastic force: the contact force of spring antenna thimble connector comes from the internal spring, and the spring elastic force will directly affect the impedance and stability of spring antenna thimble; if the elastic force is too large, the friction coefficient will be increased and the service life of spring antenna thimble will be affected.

　　For spring antenna thimble, the selection of corresponding products in different products and different use environment will be affected by factors such as price.
