[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery holder, and more particularly, to a structure that can be attached to and detached from a printed circuit board.

[0002]

2. Description of the Related Art Generally, in an electronic apparatus using a semiconductor memory, a memory is backed up by a battery in order to retain data even when a power supply is turned off. Conventionally, such a memory backup battery is attached by directly soldering it on a printed circuit board, binding it with a bundled belt, or screwing it through a bracket.

[0003]

However, in such a conventional mounting structure, an appropriate tool corresponding to each mounting structure must be prepared when replacing the battery, and the workability is poor. In addition, a space for mounting the battery on the printed circuit board must be ensured, and the space for mounting components on the printed circuit board is reduced.

The present invention focuses on such a problem, and its purpose is to replace a battery without using a special tool, and to reduce the space for mounting components on a printed circuit board by mounting the battery. It is to provide a battery holder.

[0005]

Means for Solving the Problems The present invention to solve such a problem, a Battery holder which is detachably attached to a printed circuit board having a positioning hole, so as to releasably retain the rod-shaped battery half rectangular opening is formed in a circular cylindrical
Prevent the battery from dropping in part of the opening that forms
A battery holding section for engaging pawl is provided for, opposed to the part mounting surface of the printed board of the opening edge one <br/> direction parallel opening sides forming a rectangular opening of the battery holding portion And a rectangular shape of the battery holding portion so as to be fitted to the end face of the printed circuit board.
An L-shape is formed at both ends of the other opening side of the parallel opening side forming the opening, and an L-shape is formed so that the vicinity of both ends is fitted into the positioning hole of the printed board and the printed board is sandwiched together with the spacer. And an arm portion.

[0006]

When replacing the battery, the fitting between the end of the arm and the positioning hole of the printed board is released, and the battery holder is removed from the printed board. In addition, when the battery holder is mounted on the printed circuit board, a space is formed between the battery holder and the components mounted on the printed circuit board by spacers. There is no significant reduction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a structural explanatory view showing an embodiment of the present invention,
FIG. 2 is an explanatory view of the mounting state of FIG. In the figure,
10 is a battery holder, 20 is a printed circuit board,
The battery holder 10 is detachably formed on the printed circuit board 20, and positioning holes 21 and 22 are provided near the end surface of the printed circuit board 20.

Namely, the battery holder 10, the battery holder 11 of the semicircular cylindrical to removably hold the rod-shaped battery (not shown) is formed. What
This battery has a cylindrical shape, and each end has a lead.
It is assumed that the ends of the lead wires are connected and fixed . This battery
A part of the opening side forming the rectangular opening of the terry holding portion 11
Has a locking claw to prevent the battery from dropping
ing. A flat opening forming a rectangular opening of the battery holding portion 11
The printed circuit board 2
Spacer 1 made of a protruding body so as to face the mounting surface 0
2, 13 are integrated. Battery holding part 11
Both ends 14 and 15 of the other opening side of the parallel opening side forming the rectangular opening are formed in an L-shape as an arm part.
15 are formed in an L-shape so as to face the positioning holes 21 and 22 of the printed circuit board 20, and L-shaped bent surfaces 16 and 1 near both ends of the arms 14 and 15.
7 is provided with projections 18 and 19 so as to fit into the positioning holes 21 and 22 of the printed circuit board 20.

In such a configuration, the battery holder 10 has projections 18, 19 provided on L-shaped bent surfaces 16, 17 near both ends of the arms 14, 15 in positioning holes 21, 22 of the printed circuit board 20. The printed circuit board 20 is fitted to the printed circuit board 20 by elasticity together with the spacers 12 and 13 so as to sandwich the printed circuit board 20. When the battery holder 10 is mounted on the printed circuit board 20, a space is formed between the components mounted on the printed circuit board 20 and the battery holding unit 11 by the spacers 12 and 13. Components can also be mounted on the surface of the printed circuit board 20, and the mounting space of the components on the printed circuit board 20 is not significantly affected by the attachment of the battery holder 10. In addition, when the battery holder 10 is attached to the printed circuit board 20 and the back surface of the battery holding portion 11 is in contact with a structure such as a chassis (not shown), a more stable attachment state can be obtained.

On the other hand, when removing the battery holder 10 attached to the printed circuit board 20, the L-shaped bent surfaces 16, 17 near both ends of the arms 14, 15 are used.
Is deformed to release the fitting between the projections 18 and 19 and the positioning holes 21 and 22 of the printed circuit board 20. With this configuration, it is only necessary to deform the L-shaped bent surfaces 16 and 17 near both ends of the arms 14 and 15 of the battery holder 10 when attaching and detaching the battery holder 10, so that no special tool is required. , Battery replacement work is simplified.

In the above embodiment, an example of a battery holder used for memory backup has been described.
It is also effective for various rod-shaped battery holders.

[Effects of the Invention] As described above, according to the present invention,
A battery holder can be realized that can replace a battery without using a special tool and can improve a space for mounting components on a printed circuit board by mounting the battery.
