battery connector

Technical field

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

Background technique

China Taiwan Model Patent No. M267714 discloses a battery connector. The battery connector includes an insulating base body and a plurality of conductive terminals. The insulating base body is rectangular and provided with a plurality of conductive terminal receiving grooves to accommodate the conductive terminals. The conductive terminals include a positioning part, an "S" shaped elastic part and a contact part. The positioning part bends upward toward one end of the insulating seat to form an "S"-shaped elastic part, and is accommodated together with the "S"-shaped elastic part in the terminal receiving groove, wherein the free end of the top of the "S"-shaped elastic part protrudes upwards to insulate A contact portion is formed outside the seat for contacting with the battery.

However, when the above-mentioned battery connector is in use, the contact part of the conductive terminal is pressed down and compresses the "S" shaped elastic part, so that the "S" shaped elastic part is in a tightly pressed state. The force comes from the stress of the conductive terminal itself and the positive force provided by the mutual stop between the parts of the terminal itself. After frequent use, the conductive terminal is prone to elastic fatigue, which reduces the elastic force between the conductive terminal and the battery. , thereby affecting the stable contact between the battery and the battery connector, and at the same time shortening the service life of the conductive terminal.

Utility model content

The purpose of this utility model is to provide a battery connector for the above defects, which can reduce the pressure on the conductive terminals, thereby prolonging the service life of the conductive terminals and providing a more durable and stable electrical connection.

In order to achieve the above purpose, the battery connector provided by the utility model includes an insulating base body and a plurality of conductive terminals. The groove runs through the front wall, and a stop portion is provided on the inner side of the rear wall of the insulating seat corresponding to each terminal receiving groove. The stop portion has a stop surface, which is formed by extending forward and downward from the top end; The front end of a conductive terminal is formed with an embedding plate fixed in the corresponding terminal receiving groove, the front end of the embedding plate forms a welding part protruding forward from the terminal receiving groove, and the rear end is bent upwards and extends forward to form a first connection Arm, the first connecting arm bends upwards and extends backwards to the upper part of the insulating seat to form a second connecting arm, and its free end bends upwards and extends in an arc to form a pressing part located in front of the stopping part. The end of the pressure part continues to extend upwards and then bends forward and downward smoothly to form a contact part. The first connecting arm and the second connecting arm are accommodated in the terminal receiving groove, and the contact part protrudes out of the terminal receiving groove, under the battery The pressing part in the process of pressing the contact part slides downward along the stop surface and stops on the stop surface.

As mentioned above, when the contact portion of the conductive terminal is pressed down by force, because a stop portion is provided on the inner side of the rear wall of the insulating base and the contact portion of the conductive terminal is formed above the stop portion due to the extension of the second connecting arm, so The pressing part of the conductive terminal can touch the stop part of the insulating seat after being pressed down by force, and the force can be distributed to the stop part. At this time, the force on the battery is not only the stress of the conductive terminal itself, but also The positive force provided by the stop portion of the insulating seat reduces the load on the conductive terminal, prolongs the service life of the conductive terminal, and provides more stable contact.

The top wall 11 is provided with a number of terminal accommodating grooves 16 extending longitudinally and arranged in parallel at equal intervals. These terminal accommodating grooves 16 include accommodating grooves 162 and embedded grooves 161. Extending to the bottom wall 12 , passing through the upper parts of the front wall 13 and the rear wall 14 respectively from front to back, and the receiving groove 162 is located at the front side of the bottom wall 12 of the insulating seat 10 and slightly extends to both sides to form an embedding groove 161 . A slot 17 is defined inside the side wall 15 and passes through the bottom wall 12 and the front wall 13 . A stop portion 18 is provided on the inner side of the rear wall 14 of the insulating seat 10 corresponding to each terminal receiving groove 16. The stop portion 18 has a stop surface 181, which is formed by extending forward and downward from the top end. .

Please refer to FIG. 5 , the conductive terminal 20 has a longitudinally extending embedding plate 21 , the two side edges of the embedding plate 21 near the front end are respectively provided with a groove 211 , and the middle part of the front end is bent upward to form a welding portion 22 , and the rear end The first connecting arm 23 is formed by bending upwards in an arc and extending forward. The first connecting arm 23 is bent upwards in an arc and extends backwards to the space above the stopper portion 18 of the insulating base 10 to form a second connecting arm 24 . The length of the two connecting arms 24 is greater than that of the first connecting arm 23 and slightly upwardly inclined, and the width of the first connecting arm 23, the second connecting arm 24 and the embedded plate 21 are the same and slightly wider than the terminal receiving groove 16 on the insulating base 10. The width of the notch at the top wall 11 is to prevent that when the battery (not shown in the figure) is disassembled, the elastic force of the conductive terminal 20 recovering elastic deformation will cause the second connecting arm 24 to pop out of the notch at the top wall 11 through the terminal receiving groove 16 for insulation Outside the seat body 10.
