Description

Electrical connector and electronic device with electrical connector

technical field

The utility model relates to an electric connector, in particular to an electric connector with reinforced terminal structure and an electronic device with the electric connector.

Background technique

Referring to FIG. 1, it is a conventional electrical connector 1, which is suitable for electrically connecting a circuit board 2 and a battery 3, and includes an insulating shell 11 and a plurality of terminals 12 (only one is shown in the figure). The insulating housing 11 includes a plurality of terminal accommodating grooves 111 (only one is shown in the figure) for inserting the terminals 12 respectively. Each terminal 12 includes a welding section 121, a fastening section 122 extending from the welding section 121 and used to be fixed in the corresponding terminal accommodating groove 111, and a continuous section extending from the end of the fastening section 122. The bent elastic section 123 and a contact section 124 extending from the end of the elastic section 123 are formed.

The electrical connector 1 is welded and positioned on the circuit board 2 by the welding section 121 of the terminal 12 to form an electrical connection relationship. In this way, the battery 3 can be electrically connected to the circuit board 2 through the electrical connector 1, that is, the battery 3 is approached horizontally toward the contact section 124 of the terminal 12 of the electrical connector 1 as shown by the arrow in FIG. The battery 3 touches the contact section 124 of the terminal 12 , so that the battery 3 is electrically connected to the circuit board 2 , and the elastic section 123 of the terminal 12 provides a cushioning effect when the battery 3 touches.

However, in practice, if the user does not push the battery 3 in the correct direction, such as pushing the battery 3 from top to bottom, the elastic section 123 of the terminal 12 will not be able to provide enough elasticity to buffer, thus easily causing the above-mentioned Terminal 12 deforms directly. In addition, if some users use a sharp object to press the contact section 124 into the terminal accommodating groove 111 , due to the weak structure of the terminal 12 , it is easy to deform due to excessive compression.

Once the terminal 12 is deformed, the contact section 124 between the battery 3 and the deformed terminal 12 will be in poor contact, and the battery 3 and the circuit board 2 cannot be electrically connected stably, resulting in unstable power transmission.
