[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a cable fixing structure according to the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of the present invention. FIG. 1A is a state before assembling, FIG. 1B is an assembled state, and FIG. 2 is a plan view of the embodiment.

In FIG. 1, reference numeral 1 denotes a mounting bracket,
a and side plate portions 1b formed in a bent shape from both ends thereof,
1c, and has an engagement hole 2 in one side plate portion 1b, and a mounting plate portion 1d to a device (not shown) is provided at an end of another side plate portion 1c. The main plate 1a has a screw hole 3 at a position near the side plate 1c, which is similar to the conventional one. In addition to the configuration, a protrusion 1e for preventing erroneous mounting is provided on the main plate portion 1a.
Is formed by cutting and raising.

Here, the formation position of the projection 1e is within the range of the length L1 of the engaging piece 4c of the holding member 4 from the end of the main plate portion 1a on the side plate portion 1b side as shown in FIG. The distance L2 from the tip of the projection 1e to the end of the engagement hole 2 is set to be shorter than the length L3 of the side plate 4b of the holding member 4 by a predetermined dimension. The holding member 4 has an L-shaped portion composed of a main plate portion 4a and a side plate portion 4b formed by bending the end of the main plate portion 4a as in the conventional case. An engagement piece 4c slidably engaged with the mating hole 2 is formed in such a shape as to be turned back by 90 degrees, and a through hole 5 is provided at a position corresponding to the screw hole 3 in the main plate portion 4a. The fixing screw 6 is the same as the conventional one.

Next, the operation of the above configuration will be described. First, the fixing of the cable will be described. The mounting plate 1d of the mounting bracket 1 is fixed to a wall surface of an electronic device or the like by welding or screwing. Then, the engaging piece 4c of the holding member 4 is inserted into and engaged with the engaging hole 2 of the mounting member 1, and a cable (not shown) wired to the electronic device or the like is connected to the main plate portion 1a of the mounting member 1 and the holding member. 4, the screw shaft of the fixing screw 6 is passed through the through hole 5 of the holding metal fitting 4, and the tip of the screw shaft is screwed into the screw hole 3 of the mounting metal fitting 1. By further tightening the fixing screw 6, the cable is sandwiched and fixed between the main plate portion 1a of the mounting bracket 1 and the main plate portion 4a of the holding bracket 4.

As described above, also in the present embodiment, the cable is fixed in the same manner as in the prior art, but erroneous mounting of the holding member 4 at the time of fixing the cable is prevented as follows. FIG. 3 is a plan view showing the effect of preventing the mounting error. As shown in FIG. 3, when the holding metal member 4 is mounted on the mounting metal member 1, the engaging piece 4c of the holding metal member 4 is engaged with the engaging hole of the mounting metal member 1. If not, the engaging piece 4c hits the projection 1e provided on the mounting bracket 1.

As a result, the tip of the fixing screw 6 that has passed through the through hole 5 on the opposite side of the engaging piece 4c does not reach the screw hole 3 of the mounting bracket 1, and cannot be screwed in, so that erroneous mounting is prevented. Is done. Further, in a state where the engaging piece 4c of the holding metal 4 is not engaged with the engaging hole 2 of the mounting metal 1 and the engaging piece 4c of the holding metal 4 is not in contact with the projection 1e of the mounting metal 1, the mounting metal 1 Since the holding metal 4 is largely displaced in the lateral direction or the like, the fixing screw 6 passed through the through hole 5 of the holding metal 4 is also displaced with respect to the screw hole 3 of the mounting metal 1 and fixed. Since the tip of the screw 6 cannot be screwed into the screw hole 3, erroneous mounting is prevented.

As described above, since the erroneous mounting of the holding member 4 is prevented, the worker can attach the holding member 4 in a normal state, and the cable can be securely fixed.

[0015]

As described above, according to the present invention, in order to fix the cable by providing a projection on the main plate portion of the mounting bracket, when the holding bracket is attached to this mounting bracket, the engaging piece of the holding bracket is used. If it is not engaged with the engaging hole of the mounting bracket, the engaging piece will hit the projection, or the position of the fixing screw passed through the through hole of the holding bracket and the screw hole of the mounting bracket will be shifted, and the fixing screw will be in the screw hole. So that it cannot be screwed into.

[0016] Therefore, erroneous mounting of the holding member to the mounting member is prevented, and the holding member is mounted to the mounting member in a correct state, so that the cable can be securely fixed, and the cable can be fixed. This has the effect of eliminating situations such as dropping out, or a load on the connection between the cable and the electronic device or the like, resulting in poor connection or the like.

Further, since the projections can be formed integrally with the main plate portion by cutting or raising when manufacturing the mounting bracket, the effect of not increasing the number of parts and the manufacturing cost can be obtained.
