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 downward.

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 addition, the welding part 27 has a sheet-like structure, and the electrical connection area is relatively large, so that the heat generated by the battery connector is relatively large, which affects the service life of the connector. Moreover, the area of the soldering portion 27 is relatively large, which is not conducive to the miniaturization of today's electronic products.

Utility model content
