Referring to FIGS. 4 to 6, the battery pin 1 is provided in an interface connector which is assembled with a cellular phone. The battery pin 1 is fixed in a terminal receiving portion of the interface connector and includes a pin body 2 which is bent as a coil shape so as to elastically make contact with an external battery terminal. A contact portion 3 is protruded from an upper portion of the pin body 2 so as to directly make contact with a battery terminal. A first elastic portion 4 is connected to a lower portion of the pin body 2 while forming a predetermined angle therebetween. The first elastic portion 4 is bent so as to allow the contact portion 3 to have an elastic restoring force. A second elastic portion 5 is upwardly bent towards an inner portion of the pin body 2 while making contact with a bottom of the pin body 2 so as to allow the contact portion 3 to have the elastic restoring force. A third elastic portion 6 extends from an end of the second elastic portion 5. The third elastic portion 6 is downwardly bent toward the inner portion of the pin body 2 while making contact with an inner portion of the contact portion 3 so as to apply the elastic force to the contact portion 3.
The battery pin 1 installed in the interface connector has a coil shape. That is, the pin body 2 of the battery pin 1 is inwardly rolled so that the pin body 2 makes contact with the battery terminal with an elastic energy due to bending portions thereof.
In other word, since the battery pin 1 has the coil shape, the pin body 2 has the elastic force due to the first to third elastic portions 4, 5, and 6. Accordingly, the battery pin 1 closely makes contact with the battery terminal by the elastic force.
That is, the structure of the battery pin 1 consists of the contact portion 3 which is protruded from an upper portion of the pin body 2 so as to directly make contact with a battery terminal, the first elastic portion 4 which is connected to the lower portion of the pin body 2 with forming the predetermined angle therebetween and is bent so as to allow the contact portion 3 to have the elastic restoring force, the second elastic portion 5 which is upwardly bent towards the inner portion of the pin body 2 while making contact with a bottom of the pin body 2 so as to allow the contact portion 3 to have the elastic restoring force, and the third elastic portion 6 which extends from the end of the second elastic portion 5 and is downwardly bent toward the inner portion of the pin body 2 while making contact with an inner portion of the contact portion 3 so as to apply the elastic force to the contact portion 3.
Therefore, since the elastic force is variously applied from the first to third elastic portions 4, 5, and 6, the elastic restoring force of the battery pin 1 can be improved when making contact with the battery terminal.
In addition, as shown in FIGS. 5 and 6, it is possible to adjust the elastic restoring force of the battery pin 1 by adjusting the angle between the pin body 2 and a ground terminal 7 positioned at a bottom of the pin body 2.
That is, according to the first embodiment of the present invention, as shown in FIG. 5, the angle α between an extension part 7' of the ground terminal 7 and an extension part 2' of the pin body 2, which is formed between the second and third elastic portions 5 and 6, is about 30 to 60 degrees.
In addition, according to the second embodiment of the present invention, as shown in FIG. 6, the angle β between an extension part 7' of the ground terminal 7 and an extension part 2' of the pin body 2 is about 90 degrees. In this case, the elastic restoring force of the battery pin 1 is maximized.
Therefore, the contact function of the battery pin 1 with respect to the battery terminal is improved so that people can use the cellular phone for a long time without experiencing discomfort caused by the contact error of the battery pin 1.
Industrial Applicability
