Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to protection for protecting harnesses (power cables, communication cables, electric cords, electric leads, optical fiber cables, optical fiber cords, hoses, pipes, tubes, etc. for various uses). In particular, but not exclusively, the present invention relates to a protection device for preventing a foreign object from hitting a harness for supplying electric power or an electric signal.

[0002]

2. Description of the Related Art For example, a harness provided in an electronic apparatus such as an image forming apparatus is apt to be slack depending on an installation place or an assembled state. Further, when a foreign substance, particularly a conductive substance, is dropped and adhered from a gap in the exterior of the device or the like, the harness is damaged, and a contact with another electronic device causes a short circuit to cause a failure. In the worst case, a board carrying a large current may cause smoke or ignition, which is a serious safety problem. In order to avoid these problems, it is common practice to provide a guard member that covers the harness and controls the slack.

[0003] FIG. 3 shows a conventional two typical harness protection.
Here is an example. In the embodiment shown in FIG. 3A, a metal holding cover 2 is arranged above a harness 1, a screw (not shown) is passed through a screw through hole 3, and a screw is formed in a screw hole 4 opened in a harness mounting surface 5. Screw it in. In the mode shown in FIG. 3B, the holding cover 2 is attached to the harness mounting surface 5 with a double-sided tape 6 attached to the lower surface of the holding cover 2.

[0004]

When the harness is replaced, the holding cover 2 must be removed using a screwdriver, resulting in an increase in maintenance time. Alternatively, the double-sided tape is peeled off, and it may be difficult to cleanly remove the double-sided tape, which leads to an increase in maintenance cost.

Further, according to the conventional example, since the pressing member 2 made of metal or resin is used, the state of the harness 1 in the pressing member 2 after the mounting (torsion, bending) is used.
Confirmation becomes difficult.

A first object of the present invention is to simplify attachment and detachment of a harness protection cover, and a second object is to facilitate visual confirmation of a state of a harness in a protection cover.
