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.
