technical field

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

Background technique

At present, one of the most convenient functions of electronic products such as mobile phones, personal data processors (PDAs), notebook computers, and digital cameras is that they can provide consumers with non-fixed-point use, and these electronic products themselves need to consume Electricity, therefore, miniaturized battery connectors are widely used in these electronic products. Usually, the electronic product is provided with a circuit board and a battery connector electrically connected with the circuit board. When in use, a power supply battery is inserted into the consumer electronic product and electrically connected with the battery connector, thereby providing working power to the portable electronic product.

Please refer to FIG. 1 , a common battery connector 2 suitable for general consumer electronic products includes an insulating body 22 and conductive terminals 23 . Wherein, the insulating body 22 is arranged above a circuit board 24 inside the electronic product. The conductive terminal 23 has a contact portion 26 and a welding portion 27. The contact portion 26 protrudes forward from the front end of the insulating body 22 and abuts against the external battery 25. The welding portion 27 protrudes backward from the bottom of the rear end of the insulating body 22 and Solder with this circuit board 24.

However, because the above-mentioned existing battery connector 2 is only directly welded on the surface of the circuit board 24 under the battery connector 2 through the welding portion 27 of the conductive terminal 23 to realize electrical connection. Therefore, when the battery 25 horizontally impacts the contact portion 26 of the conductive terminal 23 backward, the existing battery connector 2 tends to have a relative lateral horizontal displacement relative to the circuit board 24, thereby causing the soldering portion 27 of the conductive terminal 23 to be in contact with the contact portion 26 of the conductive terminal 23. The soldering part of the circuit board 24 is loose or shifted, thereby causing the inability to form a stable electrical connection between the battery connector 2 and the circuit board 24 , affecting the stable transmission of electrical signals. The above situation is also easy to occur when the consumer electronic product is impacted by external force.

In another improved battery connector, the welding portion of the conductive terminal extends downward from the insulating body and passes through the circuit board to be welded thereto. Although the stability of this arrangement is stronger than that of the above-mentioned battery connector 2, since the battery connector is only connected to the external circuit board through the welding part of the conductive terminal, if the connection between the conductive terminal and the insulating body is not tight enough, Then, when the battery connector welded on the circuit board is subjected to battery pressure or other external force, the conductive terminal will be deformed or the entire battery connector and the circuit board will become loose due to the excessive force of the conductive terminal, which will affect the electrical signal. Stable transmission.
