Description

[Detailed Description of the Invention] [Summary] By bringing a flexible conductor into close contact with both wings of the hinge, the electrical connection of the movable body fixed to the hinge is ensured.

[Industrial application field]

The present invention relates to electrically connected hinges.

For equipment and equipment in the electronics and communication fields, the 5th
Maintain and inspect the inside of equipment 1 etc. shown in the figure,
Alternatively, it is required to open and close the operation panel 12, etc. In such a case, one side is used as a hinge 3 and the other side is used as a releasable locking means 14, which can be released as necessary. However, since the hinge 3 is mechanically supported by the pivot 31 shown in FIG. 6, a satisfactory electrical connection is not necessarily guaranteed.

In the device 1, etc., it is preferable that by closing the panel 12, etc., the opening surface of the housing 11, etc. is also electromagnetically closed by the panel 12, etc.

[Conventional technology]

Therefore, as shown in FIG. 5, both ends of the flexible electric wire 2 are attached and connected to the vicinity of the hinge 3 that supports the opening and closing of the housing 11 and the panel 12, respectively.

[Problem that the invention attempts to solve]

According to the above-mentioned conventional technology, the connecting wire 2 is required separately, which requires securing a place to attach it, parts for attaching it, and time. In addition, since the wire 2 is provided with an allowance for bending, it is visually unsatisfactory. It cannot be said to be desirable.

[Means for solving problems]

The present invention, which aims to solve the above-mentioned conventional problems, includes a pair of blade plates rotatably connected to each other by a rotation shaft, and a pair of blades that straddles the rotation shaft. It consists of a flexible cloth-like conductor placed on the surface of the plate, and a presser plate that tightly presses and fixes the conductor to the surface of the slat, and the surface of the slat and presser plate are , each of which has a groove parallel to the rotation axis and a protrusion corresponding to the groove, and the conductor is inserted between the groove and the protrusion so as to make an electrical connection between the two blade plates. This is achieved through the implementation of

[Effect]

Since the conductor is closely fixed so as to cover the hinge body, a sufficient conductive connection surface is obtained.
Since the connection can be made using a flexible conductor attached to the hinge, no separate conductor or location is required. Moreover, the connection is extremely reliable.

〔Example〕

Hereinafter, the present invention will be described in detail by way of examples with reference to the drawings.

FIG. 1 is a perspective view of an embodiment of the hinge of the present invention, shown in a separated state. In the figure, a main body 51 of the hinge 5 has a pair of blade plates 52 and 53 attached to an intermediate rotating shaft 5.
4 so that they can rotate relative to each other. As shown in detail in FIG.
Two grooves 55 parallel to the rotation axis 54, upper and lower mounting holes 56, a fixing hole 57 between the grooves 55, and a needle-shaped projection 58 on the back surface are formed on the surfaces 2 and 53, respectively. .

As shown in detail in FIG. 3 (only one side is shown), the pair of presser plates 60, 60' have one end bent 61 and have two protrusions 62 and 62 protrusions on the back side.
A fixing hole 63 is formed between them. The protrusions 62 correspond to positions where they fit into the grooves 55 of the vanes 52 and 53.

As shown in FIG. 1, the flexible conductor 65 extends over and covers both the vanes 52 and 53 with a sufficient margin over the rotation shaft 54.

The wing plates 52, 53 and the holding plates 60, 6
0' is a brass material with good conductivity and is plated with nickel, and is a flexible conductor 65.
It is preferable that fine annealed copper wires be meshed or braided to form a cloth-like structure with multiple layers and nickel plated.

With the above configuration, the conductor 65 is arranged on the wing plates 52, 53 on both sides, the holding plates 60, 60' are applied, the rivets 66 are inserted into the fixing holes 57, 63, and the rivets 66 are caulked and fixed. Here, the conductor 65 is fitted between the groove 55 and the protrusion 62 due to its flexibility, and is tightly pressed together. Therefore, the blade plates 52 and 53 are electrically connected reliably by the conductor 65. Further, due to the flexibility of the conductor 65, the hinge can be rotated without any problem.

When the hinge 5 is attached to the mounting hole 56 using screws (not shown) in place of the conventional hinge 3 shown in FIG.
A reliable electrical contact can be achieved by pressing into the surface. Thereby, the casing 11 and the panel 12 can be connected via the hinge 5 without requiring the electric wire 2. Of course, it is maintained regardless of whether it is opened or closed.

In the hinge 5 of the present invention, when the blade plates 52 and 53 are in a parallel state, as shown in FIG.
The positions 61 and 61' are shifted from each other so that the bend 61 at 0' does not touch each other.
Further, it is not necessary to provide two protrusions 62 and grooves 55, and it is sufficient to provide at least one protrusion. The combination of protrusions and grooves may be on either side.

In addition, it goes without saying that the hinge 5 is not limited to use in cases, panels, etc., but can be applied to parts that require electrical connection between components. be.

[Effect of idea]

As described above, according to the present invention, a reliable electrical connection can be obtained by connecting the constituent members only by the hinge,
It is extremely practical as it can provide stable performance even at high frequencies.
