Description

battery connector

technical field

The utility model relates to a battery connector, in particular to a battery connector with elastic terminals.

Background technique

In mobile phones and various portable electronic devices, a battery connector is usually required to electrically connect a printed circuit board to a battery. In order to form a stable electrical contact between the battery connector terminal and the battery, the terminal used in the battery connector product body is usually an elastic terminal. Through the elastic force of the elastic terminal itself, it forms a stable electrical contact with the electrode of the battery. sexual contact.

An existing battery connector includes a housing and a plurality of terminals installed in the housing, and each terminal is made of a strip-shaped metal sheet bent multiple times. Each terminal has a retractable electrical contact end exposed from the casing and a welding end welded to the printed circuit board, and the retractable contact end can be in elastic electrical contact with the electrical contact point of the battery. The electrical contact end is connected to the welding end through the elastic main body part bent back and forth for many times, so as to provide the electrical contact end with stretchable elasticity. During use, the elastic body part that bends back and forth multiple times is elastically deformed due to the stretchable contact end being squeezed by the battery. Since the electrical contact end is generally wedge-shaped, and the through-slot of the housing through which it passes is linear, the through-slot cannot position the electrical contact end, which may easily lead to adverse consequences such as deflection of the electrical contact end of the terminal.

In another battery connector known to the inventor, each terminal includes two sub-terminals that can be separated, and the retractable first contact end exposed from the housing and the second contact end electrically connected to the printed circuit board are respectively provided On the two sub-terminals, the two sub-terminals are in slidable contact to maintain electrical connection, and an independent elastic member is provided between the two sub-terminals to provide elastic force to the first contact end.
