Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a battery storage device with a simple structure for use in equipment using batteries.

The battery storage device in the above equipment must be made precise and compact in order to downsize the equipment, but if it is made of materials that are easy to manufacture, such as resin molded products, it becomes fragile and can be easily damaged by user error. Applying excessive force may destroy the entire device.

On the other hand, in order to avoid the above-mentioned fragility, if, contrary to the above, the components of the storage device are made strong and thick, or reinforcement means are used, the device becomes larger and has a more complicated structure. This results in disadvantages such as high cost.

In view of the above, this invention can only be caused by user's erroneous operation.
That is, the object is to provide a battery storage device in which the iron cover comes off without destroying the device itself when an unnecessarily large external force is applied to the lid of the battery storage device, and which can be easily repaired by the user.

Embodiments of the present invention will be explained below based on the drawings.

Reference numeral 1 designates the lid of the battery storage device; a conical bearing is an arm 1a having a hole 1c; a conical bearing having the same shape as the arm 1a is an arm 1b having a hole 1d; and a stopper 1e and a stopper 10 having the same shape. The stopper 1f1 is further fixedly mounted with an armature terminal 3a that comes into contact with the battery pole.

The contact terminal 3a is a printed wiring board using a highly flexible polyamide film or the like as a base material, a so-called flexible printed wiring board C hereinafter referred to as FPC.

) 3b is connected.

Support members 2a and 2b are made of a highly elastic material such as synthetic resin, and have conical convex portions 2c and 2d (FIG. 2), respectively.

The base (not shown) of the support member is fixed, but the tip thereof is shaped to be flexible, as shown.

Further, the distance between the apexes of both convex portions 2c and 2d of the support member is formed to be slightly longer than the distance between the bottoms of the holes 1d and Ie of the arms 1a and 1b, and the lid 1 is attached. In this case, move the support members 2a and 2b in the direction opposite to the arrow Y19Y2.
The arms 1a and 1b are fitted into this while bending in the direction.

Therefore, the lid 1 has the above-mentioned bearings of arms 1a and 1b in holes Ic and l.
The convex portions 2c and 2d of the support members 2a and 2b fit into the support member d with the urging force in the Y1*Y2 direction, so that it is supported by the support member and can freely rotate around the center line A-A'. is set to .

Reference numeral 4 denotes a board of the device, which has a hole into which the lid 1 is fitted.

The pattern hole has dimensions in the vertical direction of the substrate 4 to allow the lid 1 to fit smoothly, and in the horizontal direction of the substrate, in addition to the horizontal length of the lid,
The iron lid is moved a certain amount in the same direction (at least 1 stopper from the iron lid)
(e, 1f overhanging length)) has a dimension including an extra play distance that allows movement.

When the lid 1 is open, the side 1 on the stopper side
g extends slightly from the side surface of the hole in the substrate 4 in the XlX2 direction.

When closing the iron lid 1, therefore, the supporting members 2a and 2
This is done by bending b in the anti-X1 direction and anti-X2 direction, respectively, and shifting this (iron lid 1) in the same direction.

FIG. 1 shows a state in which a battery (not shown) is housed and the lid 1 is closed. In this state, the iron lid 1 is attached to the support member 2.
The counter-arrow W from the battery being pushed in against the biasing force in the X□+X2 direction of a and 2b and a spring (not shown)
Due to the biasing force in the direction, the side surface 1g is attached to the side surface of the hole in the board 4,
Further, stoppers 1e and 1f are respectively crimped onto the inner edge surfaces of the holes in the substrate.

Further, the armature terminal 3a is in pressure contact with a battery pole (not shown).

When opening the lid 1, press the X (Xl) of the supporting members 2a and 2b.

When the handle 1h of the lid 1 is pushed in the direction of the arrow V against the biasing force in the direction A due to the biasing force from the battery in the opposite direction of arrow W
- It rotates in the direction of arrow R around line A' and is opened to a position where the battery can be installed and removed.

To close the lid 1 again, push the handle 1h in the direction of arrow V and rotate it in the direction opposite to arrow R, but if the stopper is shaped like 1e' in Figure 4, just rotate it in the direction opposite to arrow R. All you have to do is let it happen.

Although the FPC is bent by opening and closing the lid 1, it is not affected by the bending.

The above describes the case of normal operation, but if a large external force is inadvertently applied in the direction perpendicular to the AA' line, That is, the fitting portions 1c and 2c, and 1d and 2d, are disengaged when 2cm2d comes off from Ic and Id while the supporting member is bent against the biasing force in the direction of arrows Y1*Y2.

As explained above, since the present invention has a simple structure, each component can be made of a low-profile material such as synthetic resin that is easy to manufacture and process, thereby reducing manufacturing costs.

In addition, during normal operation, the lid is pivotally attached to the device, so there is no risk of losing it, and in the event of incorrect operation, the lid can be properly removed to prevent damage to the device, and can be easily repaired. can.

Furthermore, by using the FPC, it has become possible to always keep the lid connected to the device even when the lid comes off due to the above-mentioned erroneous operation.
