Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a protective device for protecting an installed harness (power cable, communication cable, electrical cord, electrical lead, optical fiber cable, optical fiber cord, hose, pipe, tube, etc. for various uses). Although it does not intend to limit, it is related with the protective device which prevents that a foreign material strikes the harness which supplies electricity or an electric signal.
[0002]
[Prior art]
For example, a harness provided in an electronic apparatus such as an image forming apparatus tends to sag depending on the installation location and the assembled state. In addition, when a foreign object, particularly a conductive material, drops from a gap in the exterior of the device, the harness is damaged, or a failure occurs due to a short circuit due to contact with another electronic device. In the case of a substrate in which a large current flows, the worst case is the occurrence of smoke or ignition, which is a serious safety issue. In order to avoid these problems, a guard member that covers the harness and restricts the slack is generally provided.
[0003]
FIG. 3 shows two typical examples of harness protection. 3A shows a screw hole 4 in which a metal holding cover 2 is disposed above the harness 1 and a screw (not shown) is opened through the screw through hole 3 so as to open the harness installation surface 5. It is screwed. The mode shown in FIG. 3B is a double-sided tape 6 affixed to the lower surface of the pressing cover 2, and the pressing cover 2 is bonded to the harness arrangement surface 5.
[0004]
[Problems to be solved by the invention]
When replacing the harness, the presser cover 2 must be removed using a screwdriver, which increases maintenance time. Alternatively, the double-sided tape is peeled off, and it may be difficult to remove the double-sided tape neatly, leading to an increase in maintenance costs.
[0005]
In addition, according to the conventional example, since the metal or resin pressing member 2 is used, it is difficult to confirm the attachment state (twisted or bent) of the harness 1 in the pressing member 2 after the mounting.
[0006]
The first object of the present invention is to simplify the attachment and removal of the harness protection cover, and the second object is to facilitate visual confirmation of the state of the harness in the protection cover.
[0007]
[Means for Solving the Problems]
(1) Protective cover (10) covering the harness (1); vertical arms (24, 27) for restricting lateral displacement of the harness (1), and members for restricting longitudinal movement of the protective cover (10) (25 ), And a clamper (20) for holding the protective cover (10) over the harness together with the harness (1); and the vertical arm (24, 27) in the protective cover (10) Harness protection device comprising notches (16, 17);
[0008]
In addition, in order to make an understanding easy, the code | symbol of the corresponding element of the Example shown in drawing and mentioned later is added to the parenthesis for reference. The same applies to the following.
[0009]
According to this, since the protective cover (10) is held by the clamper (20) together with the harness (1), the slack of the harness (1) is suppressed, and no fasteners such as screws are required, and the man-hours for fixing Therefore, safety can be secured with an inexpensive configuration.
[0010]
Since the notch (16, 17) of the protective cover (10) is engaged with the clamper (20), the movement of the protective cover (10) is restricted, so the clamper (20) and notch (16, 17) The protective cover (10) does not move just by managing the dimensions of the.
[0011]

[0016]
Other objects and features of the present invention will become apparent from the following examples with reference to the drawings.
[0017]
【Example】
FIG. 1 shows an embodiment of the present invention, and FIG. 1A shows the appearance of a protective cover 10 that is a pressing member. The protective cover 10 is made of a colored transparent synthetic resin and has a convex cross section. The protective cover 10 has a horizontal upper wall 11, a pair of vertical side walls 12, 13 standing vertically on both side edges and each vertical. The side walls 12 and 13 have a pair of horizontally extending walls 14 and 15 extending horizontally and a pair of notches 16 and 17 penetrating the horizontally extending walls 14 and 15.
[0018]
FIG. 1B shows the appearance of the clamper 20 that is a clamp member. The clamper 20 includes a lower beam 23 for supporting the harness (1) below, a first vertical arm 24 that stands up continuously at one end thereof and penetrates one of the notches 16 and 17 of the protective cover 10, and The harness (1) and the protective cover 10 are placed between the upper beam 25 and the lower beam 23 facing each other so that the lower beam 23 can be bent continuously. Is engaged with the second longitudinal arm 27 that can be coupled to each other, and the wedge-shaped engagement groove 28 that constitutes a locking means for maintaining the coupling between the distal end 26 of the upper beam 25 and the second longitudinal arm 27. It has an engaging claw 29. A leg 21 is continuous with the leg 22 continuing to the lower beam 23, and double-sided adhesive pieces 30, 31 are attached to the back of the leg 21.
[0019]
When the tip 26 of the upper beam 25 is pushed down so as to contact the second vertical arm 27, the engagement claw 29 of the upper beam 25 fits into the engagement groove 28 of the second vertical arm 27, and FIG. As shown, the lower beam 23, the first vertical arm 24, the upper beam 25, and the second vertical arm 27 continuously form a closed loop, and the connection between the tip 26 of the upper beam 25 and the second vertical arm 27 is maintained. .
[0020]
When protecting the harness, as shown in FIG. 1B, the tip 26 of the upper beam 25 of the clamper 20 is separated from the second vertical arm 27 and the loop is opened, as shown in FIG. Thus, after the harness 1 is received in the opening and the position of the clamper 20 is adjusted, the release paper of the double-sided adhesive pieces 30 and 31 is peeled off, and the double-sided adhesive pieces 30 and 31 of the clamper 20 are attached to the harness facing surface of the electronic device. Paste to. Then, the protective cover 10 is also inserted between the tip 26 of the upper beam 25 and the second vertical arm 27, and the clamper 20 is inserted into the notches 16 and 17 of the protective cover 10 as shown in FIG. The second vertical arm 27 and the first vertical arm 24 are received. Next, the tip 26 of the upper beam 25 is pushed down so as to contact the second vertical arm 27. As a result, the engaging claw 29 of the upper beam 25 fits into the engaging groove 28 of the second vertical arm 27, and as shown in FIG. 2B, the lower beam 23, the first vertical arm 24, the upper beam 25 and the 2nd vertical arm 27 which the loop which circulates so that the harness 1 and the protective cover 10 may be tied are formed, and the coupling | bonding of the front-end | tip 26 of the upper beam 25 and the 2nd vertical arm 27 is maintained.
[0021]
When the protective cover 10 is removed, the first vertical arm 24 and the second vertical arm 27 may be tilted so as to narrow the harness and protective cover accommodation space therebetween. As a result, the second vertical arm 27 is displaced inwardly, and is displaced outwardly from the upper beam 25 so that the engaging claw 29 is disengaged from the engaging groove 28, and the upper beam 25 jumps upward as shown in FIG. open. In this state, the protective cover 10 may be replaced.
