Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a box for housing an electric device, and more particularly to a box for housing an electric device that requires electrical communication between a main body and a door.

[0002]

[Prior Art]

 Conventionally, there is an "electronic device casing" described in Japanese Utility Model Application Laid-Open No. 61-134085 as an example of electrically connecting between a main body of a box that houses electrical devices and a door. FIG. 6 shows a connection structure between a main body and a door in a general electric equipment housing box, not limited to the above “electronic equipment casing”. As shown in FIG. 6, the conventional electric equipment housing box is provided with a hinge 23 for attaching the door 22 to the main body 21 so that the door 22 can be opened and closed, and electrically connects the main body 21 and the door 22 to each other. The main body 21 and the door 22 are configured to be connected by an electric wire 24. Therefore, both the main body 21 and the door 22 are provided with screw holes for fixing the terminals 24A, 24B connected to both ends of the electric wire 24, and the terminals 24A, 24B are screwed with the screws 25, 26, respectively. It is fixed to.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional electrical equipment housing box, since the main body 21 and the door 22 are electrically connected to each other, both the main body 21 and the door 22 need to be screwed as described above. Therefore, there is a problem that holes are opened in both the main body 21 and the door 22, and in order to prevent this, it is necessary to weld metal fittings for processing the screw holes to both the main body 21 and the door 22, which makes the structure complicated. There's a problem. Further, due to the existence of the electric wires 24, there is a problem that the space for storing electrical equipment and the like is reduced. Further, if the length of the electric wire 24 is made sufficiently long, the door 22 can be sufficiently opened, but there is a problem that the electric wire 24 is sandwiched between the main body 21 and the door 22. When the length of 24 is shortened, there is a problem that the opening degree of the door 22 becomes small.

Therefore, in the present invention, the door can be sufficiently opened by electrically connecting the main body and the door without using an electric wire, and the structure of the electrical equipment storage box can be simplified and The technical issue to be resolved is to ensure that the equipment storage space can be sufficiently secured.

[0005]

[Means for Solving the Problems]

 The technical means for solving the above-mentioned problems is a hinge made of a conductive material which is integrated by inserting one hinge pin into a main body side hinge attached to a main body and a door side hinge attached to a door. A box for electrical equipment storage configured to open and close the door via a hinge is provided with a conductive elastic member interposed between the hinge pin and each of the main body side hinge and the door side hinge. By electrically contacting the elastic members with each other and electrically contacting each elastic member with the main body side hinge and the door side hinge, the main body and the door are electrically connected via the hinge. Is to be configured.

[0006]

[Action]

 According to the electrical equipment storage box having the above configuration, the conductive elastic member is interposed between the hinge pin and each of the main body side hinge and the door side hinge, so that the main body-main body side hinge-main body side hinge is contacted. The main body and the door are electrically connected to each other by a conduction path of the elastic member-the hinge pin-the elastic member in contact with the door-side hinge-the door-side hinge-the door.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a conductive body integrated by inserting one hinge pin 4 into a main body side hinge 2 welded to a main body A of an electric equipment housing box and a door side hinge 3 welded to a door B. FIG. 3 is a perspective external view showing a part of the hinge 1 made of a material, and FIG. 2 is a vertical sectional view of the hinge 1. As shown in FIG. 2, ring-shaped coil springs (elastic members) 5 and 6 are interposed between the hinge pin 4 and the main body side hinge 2 and the door side hinge 3, respectively. Since 6 is made of a conductive material, the coil spring 5 conducts the door side hinge 3 and the hinge pin 4 while the coil spring 6 conducts the main body side hinge 2 and the hinge pin 4 so that the main body A Between doors B, a main body side hinge 2-coil spring 6-hinge pin 4-coil spring 5-door side hinge 3 is formed, and the main body A and the door B are electrically connected. Even if paint is attached to the holes on the main body side hinge 2 and the door side hinge 3 through which the hinge pins 4 are inserted, the coil springs 5 and 6 are attached to the peripheral surfaces of the holes as the door B is opened and closed. Since it slides on, the paint will peel off immediately and there will be no hindrance to electrical conduction.

As shown in FIG. 3, spring grooves 4A and 4B, into which the coil springs 5 and 6 are mounted, are formed on the peripheral surface of the body of the hinge pin 4, and the respective coil springs 5 and 6 are displaced. Is guided so as not to cause.

Next, a modified example will be described. In the first modification, as shown in FIG. 4, holes 4C and 4D are formed in the body of the hinge pin 4, and compression springs 7 and 8 are attached to the holes 4C and 4D, so that the compression spring 7 can be removed from the door. The side hinge 3 and the hinge pin 4 are electrically connected, and the compression spring 8 electrically connects the main body side hinge 2 and the hinge pin 4 to each other. As a result, a conduction path is formed between the main body A and the door B, that is, the main body side hinge 2-compression spring 8-hinge pin 4-compression spring 7-door side hinge 3, and the main body A and the door B are electrically connected. Connected to.

Further, in the second modified embodiment, as shown in FIG. 5, through holes 4E and 4F are opened in the body portion of the hinge pin 4, and wire springs 9 and 10 are provided in the through holes 4E and 4F. When inserted, the spring 9 makes the door side hinge 3 and the hinge pin 4 conduct, and the spring 10 makes the main body side hinge 2 and the hinge pin 4 conduct. As a result, a conduction path of main body side hinge 2-spring 10-hinge pin 4-spring 9-door side hinge 3 is formed between the main body A and the door B, and the main body A and the door B are electrically connected. It

[0011]

[Effect of the device]

 As described above, according to the present invention, since the electrical connection between the main body and the door can be made via the hinge, the structure of the electrical equipment housing box can be simplified and the cost can be reduced. There is an effect that you can. Also, since it is no longer necessary to connect an electric wire between the main body and the door as in the past, there is no need to make a hole for connecting the electric wire to the main body and the door, which simplifies the assembly process and is often seen in the past. It is possible to eliminate problems such as electric wire cutting and pinching. Further, since no electric wire is used, the space for storing electrical equipment can be widened and the door can be opened sufficiently.
