Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a battery holder, and more particularly, to a structure attachable to and detachable from a printed circuit board.

[0002]

[Prior Art]

 Generally, in an electronic device using a semiconductor memory, a memory is backed up by a battery in order to retain data even when the power is off. Conventionally, when mounting such a memory backup battery, it has been performed by directly soldering it on a printed circuit board, binding it with a bundling belt, or screwing it through a bracket.

[0003]

[Problems to be solved by the device]

 However, in such a conventional mounting structure, when replacing the battery, it is necessary to prepare an appropriate tool according to each mounting structure, and workability is poor. In addition, it is necessary to secure a space for mounting the battery on the printed circuit board, which reduces the component mounting space on the printed circuit board.

The present invention focuses on such a problem, and an object thereof is to replace a battery without using a special tool and improve a reduction of a component mounting space of a printed circuit board by mounting a battery. It is to provide a battery holder.

[0005]

[Means for Solving the Problems]

 The present invention, which achieves such an object, is a battery holder that is attached to and detached from a printed circuit board. The battery holder is formed in a semi-cylindrical shape so as to detachably hold a rod-shaped battery, and the battery holder. One part of the opening side of one of the opening sides of the battery holding part so as to fit on the end surface of the printed board And L-shaped arms that are formed in L-shapes on both ends and that fit in the positioning holes of the printed circuit board near the both ends and hold the printed circuit board together with the spacers. To do.

[0006]

[Action]

 When replacing the battery, remove the battery holder from the printed circuit board by releasing the fitting between the end of the arm and the positioning hole of the printed circuit board. Also, when the battery holder is attached to the printed circuit board, a space is formed by the spacer between the battery holding part and the components mounted on the printed circuit board. Does not significantly reduce

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a structural explanatory view showing an embodiment of the present invention, and FIG. 2 is an explanatory view of a mounted state of FIG. In the figure, 10 is a battery holder and 20 is a printed circuit board. The battery holder 10 is detachably attached to the printed circuit board 20, and positioning holes 21 and 22 are provided near the end surface of the printed circuit board 20.

That is, the battery holder 10 is formed with a semi-cylindrical battery holding portion 11 provided with locking claws for detachably holding a rod-shaped battery (not shown). Spacers 12, 13 made of protrusions are integrated with a part of one opening side of the battery holding portion 11 so as to face the mounting surface of the printed circuit board 20. Both ends 14 and 15 of the other opening side of the battery holding part 11 are formed into L-shapes as arms, and the vicinities 16 and 17 of both ends of the arms 14 and 15 face the positioning holes 21 and 22 of the printed circuit board 20. L-shaped bent surfaces 16 and 17 in the vicinity of both ends of the arm portions 14 and 15 are provided with protrusions 18 and 19 so as to fit into the positioning holes 21 and 22 of the printed circuit board 20. ..

In the battery holder 10 having such a configuration, the protrusions 18 and 19 provided on the L-shaped bending surfaces 16 and 17 near both ends of the arm portions 14 and 15 have the positioning holes 21 and 22 of the printed circuit board 20. It is attached to the printed circuit board 20 so that the printed circuit board 20 is sandwiched by the spacers 12 and 13 and is elastically held. When the battery holder 10 is attached to the printed circuit board 20, a space formed by the spacers 12 and 13 is formed between the components mounted on the printed board 20 and the battery holding portion 11, so that the lower portion of the battery holding portion 11 is covered. Components can also be mounted on the surface of the printed circuit board 20, and the mounting space of the component of the printed substrate 20 is not greatly affected by the attachment of the battery holder 10. Further, when the battery holder 10 is attached to the printed circuit board 20, the back surface of the battery holding portion 11 is in contact with a structure such as a chassis (not shown), so that 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 and 17 near both ends of the arm portions 14 and 15 are deformed to form the protrusions 18 and 19 and the printed circuit board. Release the fitting of the positioning holes 21 and 22 of 20. With this configuration, when attaching and detaching the battery holder 10, it is only necessary to deform the L-shaped bending surfaces 16 and 17 near both ends of the arm portions 14 and 15 of the battery holder 10, and no special tool is required. Yes, battery replacement work becomes easier.

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

[0012]

[Effect of the device]

 As described above, according to the present invention, a battery holder can be realized in which the battery can be replaced without using a special tool and the reduction of the component mounting space of the printed circuit board by mounting the battery can be improved.
