What parameters need to be told to the manufacturer for custom spring charging needles,antique thimb

　　Now many electrical appliances are gradually using spring charging needles, such as Bluetooth headsets, electrodes, electric heaters, power banks and other electronic products, so the competition among spring charging needle manufacturers is very large. What parameters do customers need to tell the manufacturer if they want to customize the spring charging pin of their own size? The following Jingcheng editor will explain to you what parameters are required:

　　1. Selection of working stroke of spring charging needle:

　　When choosing a spring charging needle, it must be determined according to the space of the product used, and it should be selected within the working stroke range.

　　2. Compression selection of spring charging needle:

　　If the space is too small, the spring of the spring charging pin will be over-compressed, which will have a great impact on the service life. If the space is too large, the contact may not be in place, and the impedance will be unstable and instantaneously cut off.

　　3. Selection of electroplating materials for spring charging needles:

　　Electroplating materials can increase conductivity, prevent oxidation, and resist wear in spring charging pins. Different materials have different effects. For example, gold has good electrical conductivity. For high-current connectors, high impedance requirements The products usually use electroplated gold.

　　Fourth, the influence of the thickness of the electroplating film of the spring charging needle:

　　When the spring charging needle is working, it will wear for a long time because it must be in contact with a certain friction time. The thickness of the electroplating film also has a great influence on the service life of the product.

　　5. The influence of the life of the spring charging needle:

　　When used to a certain extent, the plating layer will be worn away, and the resistance may be too large, and the impedance may be unstable. The electroplating layer of the 100,000-time pogo pin is definitely much thicker than that of the 10,000-time pogo pin. Therefore, please select the electroplating requirements according to your needs when selecting products.

　　6. The influence of spring charging needle elasticity:

　　The contact force of the spring charging needle comes from its internal spring. The size of the spring force will directly affect the impedance of the spring thimble and its stability; if the elasticity is too large, it will increase the friction coefficient, which will affect the service life of the spring charging needle. influence.
