Abstract

(57) [Abstract] [Purpose] To provide a chip-type battery terminal board that can be automatically mounted and has a high degree of freedom in installation. A coil spring 7 is housed in a coil spring housing groove 4 of an insulating housing 1. The battery contact terminal 7a of the coil spring 7 is projected outward from the battery mounting surface 1a of the insulating housing 1. The flat terminal conductor 8 is inserted into the coil spring 7 by penetrating a part of the insulating housing 1 and electrically contacting the inner circumference thereof. One surface of the surface-mounting terminal portion 8a of the flat terminal conductor 8 is aligned with the printed circuit board mounting surface 1b of the insulating housing 1 at the same height.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a chip-type battery terminal board used for connecting a battery pack in, for example, audio equipment and video equipment.

[0002]

[Prior art]

 As shown in FIG. 9, a conventional battery terminal plate has a coil housing for a positive electrode with a battery contact terminal 2 for a positive electrode and a coil spring for a negative electrode with a battery contact terminal 3 for a negative electrode in a common insulating housing 1. It was a structure that was installed at different positions in different directions.

[0003]

[Problems to be solved by the device]

 However, such a battery terminal plate has a problem that it cannot be automatically mounted because it is long and large. Further, in such a structure, there is a problem that the degree of freedom in using vertically or horizontally is poor.

An object of the present invention is to provide a chip type battery terminal board that can be automatically mounted and has a high degree of freedom in installation.

[0005]

[Means for achieving the object]

 To achieve the above object, the structure of the present invention will be described.The chip type battery terminal board according to the present invention has one surface as a battery mounting surface and the other surface as a printed circuit board mounting surface. The chip-type insulating housing has a coil spring receiving groove in which the coil spring for one polarity is accommodated, and the battery contact terminal formed by a part of the coil spring is provided in the battery mount. A flat terminal conductor is inserted into the coil spring through a part of the chip-shaped insulating housing and is electrically connected to the tip end of the flat terminal conductor. One feature of the surface mounting terminals is that they are arranged with their heights aligned with the printed circuit board mounting surface. To.

[0006]

[Action]

 Since such a chip type battery terminal board has a small structure in which only one polarity component is incorporated, it can be automatically mounted by emboss taping or stick taping. Also, because the structure for the positive electrode and the structure for the negative electrode are separated, the degree of freedom in installation is increased. Further, the same one can be used for the positive electrode and the negative electrode.

[0007]

【Example】

 1 to 6 show a chip-type battery terminal board according to the present invention. This battery terminal board has a battery mounting surface 1a on one side and a printed circuit board on the opposite side. The insulating housing 1 serving as the mounting surface 1b is used.

On one side of the insulating housing 1, a pair of coil spring accommodating grooves 4 and battery contact terminal through holes 5 opened on the printed board mounting surface 1 b are provided facing each other with the partition wall 6 as a boundary. Has been.

A coil spring 7 is housed in the coil spring housing groove 4. As shown in FIG. 7, a battery contact terminal 7a is integrally formed on one end of the coil spring by utilizing a part thereof. The battery contact terminal 7a projects from the battery contact terminal through hole 5 to the battery mount surface 1a.

A flat terminal conductor 8 is used to fix the coil spring 7 to the insulating housing 1 and to serve as a terminal of the coil spring 7. As shown in FIG. 8, the flat terminal conductor 8 is formed by bending the base end portion of the conductive metal plate material at a right angle in the thickness direction and then bending the tip end portion at a right angle again in the thickness direction. 8a is provided.

The flat terminal conductor 8 is press-fitted into a hole such as the partition wall 6 of the insulating housing 1 and inserted into the coil spring 7. The flat terminal conductor 8 is in contact with the inner circumference of the coil spring 7 to be electrically connected. Since the flat terminal conductor 8 penetrates a part of the insulating housing 1, the coil spring 7 is attached to the insulating housing 1, and the flat terminal conductor 8 itself is also attached to the insulating housing 1. The surface mounting terminal portions 8a are arranged such that one surface thereof is aligned with the surface of the printed circuit board mounting surface 1b with the same height.

In this case, for each coil spring 7, the flat terminal conductor 8 is inserted into the insulating housing 1 from the opposite side so that the surface mounting terminal portions 8 a are present on both sides of the insulating housing 1. It is preferable.

Two such chip type battery terminal boards are placed on a printed circuit board at a predetermined interval and soldered and fixed by surface mounting at the surface mounting terminal portions 8a. At this time, if the surface mounting terminal portions 8a are present on both sides of the insulating housing 1 as described above, the chip type battery terminal plate can be stably fixed to the printed circuit board.

At the time of surface mounting, the chip-type battery terminal board is embossed or stick-taped and supplied to a surface mounting machine.

In particular, as shown in FIG. 1, when the two coil springs 7 are separately supported by the flat terminal conductors 8 and are electrically independent, electrical connection and a switch mechanism can be provided together.

[0016]

[Effect of device]

 As described above, the chip-type battery terminal board according to the present invention has a small structure in which only one polarity component is incorporated, so that it can be automatically mounted by emboss taping or the like. Also, since the structure for the positive electrode and the structure for the negative electrode are separated, there is an advantage that the degree of freedom in the installation method is increased. Furthermore, there is an advantage that the same one can be used for both the positive electrode and the negative electrode. Particularly, in the present invention, since the flat terminal conductor is used in addition to the coil spring, it is possible to easily cope with chip type mounting. Moreover, since this flat terminal conductor is in contact with the inner circumference of the coil spring, it does not require soldering with the coil spring and also penetrates a part of the insulating housing. There is an advantage that can be fixed.
