What are the advantages of thimble and shrapnel connectors

　　Commonly used battery connectors have two forms of thimble type and shrapnel type connectors. A large number of battery connectors used in mobile phones are thimble type. Compared with shrapnel type battery connectors, it has the following advantages.

　　When comparing the ejector pin connector and the same size shrapnel connector, the compression is larger and the contact is more stable. The ejector pin battery connector also has a more effective working compression than the shrapnel type, confirming the stability of the contact.

　　When comparing the ejector pin type and the shrapnel type with the same compression amount, the ejector pin connector occupies less PCB board space. When the working position is 4mm and the compression is 1mm, the thimble connector occupies less space on the PCB board. The body can be made thin and miniaturized.

　　When compressed, the position of the contact point of the thimble connector does not change, which can maintain a stable connection point and obtain stable electrical performance. The thimble type is 20,000 times and the shrapnel type is 5,000 times. The durability of the thimble type battery connector is stronger than that of the shrapnel type. The shape of the plastic gel and the combination of the thimble can be set freely, so the degree of freedom of design is more prominent.

　　Through the above comparison and analysis, the thimble type connector has more advantages than the shrapnel type: it can make full use of the PCB board space; the thimble type connector can ensure a high initial contact pressure, compared with the previous shrapnel connector It has a stable contact pressure; the thimble-type connector has a higher working life than the shrapnel-type connector; the design freedom is also higher. In the design of new models in the future, it is best to use thimble-type battery connectors for battery connectors.
