Description

Double-sided shrapnel battery connector

technical field

The utility model relates to a battery connector, in particular to a double-sided shrapnel type battery connector electrically connecting a battery with a circuit board of a portable electronic device.

Background technique

The electrical connection between the battery and the circuit board of the portable electronic device is generally realized through a battery connector, and the battery connector generally includes an insulating body and a conductive terminal. Due to the need to minimize the size and weight of portable electronic devices, battery connectors must be designed to be as small and compact as possible.

The existing battery connector mainly adopts a single shrapnel battery connector, and its structure is shown in Figure 1: it includes an insulating body A with several terminal accommodating grooves A1, and several terminals B are arranged in the accommodating groove A1. The upper end of the terminal B is an n-shaped elastic sheet structure B1, and the lower end is a linear welding part B2. When connecting with the circuit board of a portable electronic device, please refer to Figure 2. The linear welding part B2 of the connector terminal B is connected to the circuit board through SMT welding, and the elastic piece structure B1 at the other end is connected to the elastic piece on the battery. As mentioned above, the existing single shrapnel battery connector requires soldering and solder paste when connecting to the circuit board, which increases the raw material cost and manufacturing cost. In addition, such battery connectors are not suitable for portable electronic devices with two batteries.

Utility model content

The purpose of this utility model is to provide a double-sided shrapnel battery connector, which mainly solves the problem that the existing single shrapnel battery connector needs welding and solder paste when connecting with the circuit board, which increases the raw material cost and manufacturing cost. Technical issues, applicable to portable electronic devices with two batteries.

For solving the problems referred to above, the utility model is achieved in that:
