JPH0515039A - Cable protection structure - Google Patents

Abstract

PURPOSE:To make a cable protector cheaply and without side run-out and with small space, in a casing of such structure as to pull out interior equipment. CONSTITUTION:A projection 2 is provided in a piece 1, which constitutes a cable protector, and guide holes are provided in the floor of a casing and the bottom 8 of interior equipment 10 which becomes the target of the pullout, and the projection engages with the guide hole. Hereby, a cable protector can be manufactured cheaply.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable protection structure.

[0002]

2. Description of the Related Art As a publicly known example close to the present invention, Japanese Utility Model Publication No. 62-
There is 11139.

This known example is not used so much because it requires a lot of man-hours for mounting, it is difficult to mount a round cable, and there are problems in protecting the cable from damage and the like.

[0004]

In the conventional method, the pieces are connected in a chain shape. However, in order for the pieces to move smoothly, a horizontal fit between the pieces and the connecting pins and the pieces are slightly different from each other. Has a gap.

When a large number of pieces are connected, these gaps are accumulated, and when the cable protector moves left and right, a phenomenon of twisting in the horizontal direction occurs, which may cause interference with other mounted objects. is necessary.

Since the conventional method requires this guide, there is a drawback that the mounting space is increased, the number of parts is increased, and the cost is increased.

[0007]

The present invention solves the problems by providing a protrusion on each piece in order to eliminate this guide, and providing a hole for engaging the protrusion on the housing side and a movable mount. It was to be.

[0008]

[Function] Before moving the interior equipment, the cable protector composed of the chain-connected pieces is provided with a large number of protrusions provided on each piece on the bottom of the interior equipment, as well as holes provided on the housing side. The cable protector does not move sideways by engaging several holes.

When the internal equipment is pulled out to check the equipment, the U-shaped portion of the cable protector moves as the internal equipment moves.

At this time, regarding the state of the holes engaging with the protrusions of the respective pieces, the protrusions meshing with the holes on the housing side are engaged one by one, and conversely, the holes provided on the lower surface of the internal equipment. The number of engagements of the and projections is increased by one, and the total number of engagements remains unchanged from the initial state.

Therefore, the cable protector does not laterally swing at any position of the drawer of the internal equipment.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As a concrete example of the embodiment of the present invention, as shown in FIG. 3, a guide hole 6 is provided in a floor 5 of a housing, and a guide hole is similarly provided in a bottom surface 8 of an internal equipment. FIG. 5 shows an example of guide holes on the floor of the housing.

As shown in FIG. 3, the cable protector is composed of fixing metal fittings 4, 9, a piece 1, and a shaft 3, and a fixing metal fitting 4
Is fixed to the bottom surface 8 of the interior equipment by fixing the housing floor 5 to the bottom surface 8 of the internal equipment. The fixing metal fittings 4, 9 and the piece 1 are connected to the piece rear end 1'by the shaft 3 and the piece comrades by the shaft 3.

The cable 7 is housed in the piece 1 as shown in FIG. 4 (partial cross section of FIG. 3).

When the interior device 10 is moved to the left or right by the operation of pulling it out of the housing for maintenance or the like, the cable protector is
The engagement between the guide holes on the floor 5 of the housing and the protrusions 2 on the piece 1 is gradually increased, while the number of engagements with the guide holes on the bottom surface 8 of the interior device 10 is increased to constantly engage a fixed number. Keep
It does not laterally move even when the cable is pressed in the lateral direction.

1 and 2 show an example of a conventional example, a guide 11 is provided to prevent lateral blurring.

[0017]

According to the present invention, the guide is unnecessary and the cable protector can be manufactured at low cost. Further, there is an effect that the space occupied by the cable protector is reduced.
