DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coaxial cable mounting structure for fixing a coaxial cable to a substrate or the like.

[0002]

2. Description of the Related Art In general, a coaxial cable is mainly used as a signal cable, which is a wiring cable to a transmitting and / or receiving antenna such as a TV and a transceiver. 2 may be directly fixed with solder or the like, or may be mounted via a mounting bracket 1 fixed on a substrate as shown in FIG.

That is, in the conventional coaxial cable mounting structure shown in FIG. 2, the main fixing portions 2a, 2a of the mounting bracket 1 are provided.
In the meantime, the coaxial cable 3 is inserted in the axial direction indicated by the arrow to position the braided wire 3a, and at the same time, the core wire 3b at the tip is inserted between the pedestal portion 4a of the core wire fixing portion 4 and the plate 4b,
The core wire 3b is screwed through the plate 4b to the pedestal portion 4a.
Fixed to. Further, the braided wire 3a of the coaxial cable 2 is fixed by being tightened to the main fixing portions 2a, 2a by the respective screws 7.7 via another plate 6 extending between the main fixing portions 2a, 2b. In addition, 4c, 4c is the pedestal part 4a.
The flaps vertically stand on both sides of the core wire 3b, thereby preventing the core wire 3b from falling off in the left-right direction.

[0004]

According to the mounting bracket 1 having the above structure, when the coaxial cable 3 is mounted, the screws 5, 7, and 7 are first loosened, and
Since the cable 3 must be inserted with the b and 6 lifted up, the workability is extremely poor, such as the braided wire 3a getting stuck in the plate 7 or the core wire 3b being bent without entering the gap properly. . Also, core 3
There is also the problem that the cable length must have a margin for the installation by insertion of the cable b, which is also inconvenient.

[0005]

In order to solve the above-mentioned problems, the present invention comprises a core fixing portion and a main fixing portion for fixing a core wire and a braided wire of a coaxial cable, respectively, and the core fixing portion is The main fixing portion includes a pair of pedestals, and has a pivot point at one of the pedestals so as to be orthogonal to the axis of the coaxial cable. An object of the present invention is to provide a coaxial cable mounting structure comprising a rotating plate and a fixing member fixed to the other pedestal portion at a free end of the plate.

[0006]

FIG. 1 shows an embodiment of a coaxial cable mounting structure according to the present invention. That is, according to the coaxial cable mounting structure of the present invention, the mounting bracket 10 has the pedestal portion 12a of the core wire fixing portion 11 for fixing the core wire 3a formed in the same manner as in the above-described conventional art, On the other hand, one of the flaps 12c, 12c for regulating the left and right directions is widened by a predetermined angle on the upper surface of the pedestal portion 12a, and the angle θ of the flap 12c is too large for the upper surface of the pedestal portion 12a when the core wire 3b passes through the plate 12b from above. Is a preferred embodiment. It is sufficient that at least one of the flaps 12c is expanded.

On the other hand, the pedestals 15a, 15a of the main fixing portion for fixing the braided wire 3a are also basically similar in construction to the above-mentioned conventional one, but a plate 16 for fixing the braided wire 3a is provided at one end thereof. Is configured to rotate toward the other pedestal portion 15a side around a rotation fulcrum (axis) 17 formed on one pedestal portion 15a. A screw 18 provided at the free end of the plate 16 is screwed into a screw hole 15b formed in another pedestal 15a.

Here, an embodiment will be described in which the coaxial cable 3 is attached to a substrate or the like using the metal fitting 10.

Screw 1 of core fixing part 11 and main fixing part 14
When the plates 16 are expanded around the pivot point 17 as shown in the figure and the coaxial cable 3 is lowered from above as shown by the arrow, the core wire 3b is expanded.
From 12c, the situation of the pedestal part 12a is reached. Then, the screw 16 may be screwed into the screw hole 15b by rotating the flat 16 as shown by the two-dot chain line, and the other screws 13 may be screwed in the same manner.

Accordingly, the number of fastening screws can be reduced and the number of assembling steps can be reduced, and the coaxial cable 3 can be easily mounted simply by arranging it from above. For this reason, no excessive force acts on the core wire 3b, and it is possible to smoothly attach and detach the core wire 3b, and the attachment becomes extremely easy even if there is no margin in the length of the cable.

[0011]

As described above, according to the present invention, only by arranging the coaxial cable on the mounting portion from above, the core wire and the braided wire can be securely positioned and fixed, and the mounting operation can be performed. The effect is that the components are good and the number of components is reduced.
