Spring thimble considerations for connector selection

　　1, spring thimble connector working stroke selection

　　 When choosing a spring thimble connector, you must make a choice according to the actual use of the product space, and choose the one within the working stroke range. Because the space is too small, it will cause excessive compression of the spring of the spring thimble connector, thereby reducing the service life. If the space is too large, the contact will not be in place, and the impedance will be unstable, and the phenomenon of instantaneous breakage will occur.

　　2, the choice of plating materials

　　Plating materials play a role in improving conductivity, avoiding oxidation, and anti-wear in spring thimble connectors. Due to different materials, their functions are also different. For example, gold has good electrical conductivity. Therefore, electroplated gold is usually used for high-current connectors or products with high impedance requirements.

　　3. The influence of plating film thickness

　　 Spring thimble connector will have a certain amount of friction during the working process, and wear will occur once a long time, and the thickness of the electroplating film will have a great impact on the service life of the product, and it will be used to a certain limit When the electroplating layer is worn away, the resistance will increase, and the impedance will be unstable. Therefore, the electroplating demand must be determined according to the actual demand when the product is selected.

　　4. The influence of elasticity

　　 The contact force of the spring thimble connector comes from the internal spring. The magnitude of the spring force will directly affect the impedance and stability of the spring thimble. If the elasticity is too large, it will increase the friction coefficient, thereby reducing the service life of the spring thimble.

　　 The above four aspects are the items that need to be paid attention to when choosing a spring thimble connector, so choose suitable products and prices for different use environments.
