2. Description of the Related Art A coaxial cable is composed of an insulator covering a center conductor, an outer cylindrical conductor provided coaxially with the center conductor on the outer periphery of the insulator, and an insulator covering the outer conductor. A communication cable with an inner and outer conductor as a reciprocating line, and hardly leaks electromagnetic waves to the outside.For example, it is widely used for transmission of various high-frequency signals, such as telephone lines and television lines. .

FIG. 7 shows a conventional example of a fixing bracket for a coaxial cable for connecting and fixing such a coaxial cable to an electric circuit. The fixing bracket 1 for a coaxial cable shown here is disclosed in Japanese Patent Application Laid-Open No. 10-21978. The coaxial cable 3 to be fixed is formed by folding the outer conductor 3b, which is previously exposed by peeling off the insulating outer coating 3a, onto the outer coating 3a to form an outer conductor fixing portion 3c.
Further, by cutting off the insulator 3d inside the outer conductor 3b over a predetermined length, a center conductor fixing portion 3f exposing the center conductor 3e over a predetermined length is formed.

The above-mentioned fixing bracket 1 for a coaxial cable includes an outer conductor fixing bracket 7 for fixing the outer conductor 3b at a predetermined position on the substrate 5, and a center conductor fixing bracket for fixing the center conductor 3e at a predetermined position on the substrate 5. 9 is provided.

The external conductor fixing bracket 7 includes an external conductor connection terminal plate 11 having an external conductor contact portion 11a for contacting the external conductor 3b, and an external conductor for pressing the external conductor 3b at a position opposed to the external conductor contact portion 11a. It has a conductor pressing portion 13a and an external conductor pressing plate 13 whose both ends are fastened to the external conductor connecting terminal plate 11 by screw members 15, 15, respectively. This external conductor fixing bracket 7
The external conductor 3b is formed by sandwiching the external conductor fixing portion 3c between the external conductor connection terminal plate 11 and the external conductor holding plate 13.
Is fixed at a fixed position on the substrate 5, and at the same time, a circuit (usually a ground circuit) on the substrate 5 electrically connected to the external conductor connection terminal plate 11 is electrically connected to the external conductor 3b.

The center conductor fixing bracket 9 has a center conductor connection terminal plate 17 having a center conductor contact portion 17a for contacting the center conductor 3e, and a center conductor holding portion 19a at a position facing the center conductor contact portion 17a. And a core pressing plate 19 fastened to the connection terminal plate 17 for the central conductor by a single screw member 21. This center conductor fixing bracket 9
Is to fix the center conductor 3e at a fixed position on the substrate 5 by sandwiching the center conductor 3e between the center conductor connection terminal plate 17 and the core wire holding plate 19, and at the same time,
7 and the center conductor 3e which are electrically connected to the substrate 5.
Make an electrical connection with the

[0007] The center conductor connecting terminal plate 17 is provided at both ends of a flat center conductor contact portion 17a with rotation restricting walls 17b, 1b.
7c are continuously provided. These rotation regulating walls 17b, 1
Reference numeral 7c abuts on both side end surfaces of the core wire holding plate 19 to prevent the core wire holding plate 19 from rotating.

[0008]

When the outer conductor 3b of the coaxial cable 3 is fixed to the outer conductor fixing bracket 7, the outer conductor pressing plate 13 and the outer conductor fixing plate 13 are fixed. First, two screws for fastening the external conductor holding plate 13 to the external conductor connection terminal plate 11 so that a gap between the connection terminal plate 11 and the external conductor fixing portion 3c can be freely inserted and removed. It is necessary to loosen the member 15 and then insert the external conductor fixing portion 3c into the gap between the external conductor holding plate 13 and the external conductor connection terminal plate 11, and then retighten the two screw members 15 again. Therefore, there is a problem that the operation of loosening or tightening each of the two screws is troublesome and the workability is poor.

Further, the surface of the substrate 5 on which the fixing bracket 1 for a coaxial cable is mounted is not limited to an upward state as shown in the figure, but may be installed in a vertical upright state or downward. In the case of such an attachment posture, when the two screw members 15 are loosened, the two screw members 15 are excessively loosened, and there is a possibility that the external conductor pressing plate 13 or the screw member 15 may come off.

When fixing the center conductor 3e of the coaxial cable 3 to the center conductor fixing bracket 9, the center conductor fixing portion 3 is provided between the core wire holding plate 19 and the center conductor connection terminal plate 17.
First, the core wire holding plate 19 is connected to the center conductor connecting terminal plate 17 so that a gap can be secured so that the f can be freely inserted and removed.
After the screw member 21 is loosened, the center conductor fixing portion 3f is inserted into a gap between the core wire holding plate 19 and the center conductor connection terminal plate 17, and then the screw member 21 is tightened again. However, the center conductor fixing portion 3f is thin, and the gap between the core wire holding plate 19 and the center conductor connection terminal plate 17 is a fine hole penetrating in the axial direction of the center conductor 3e. The tip of the center conductor 3e is hardly bent because it hits the edge of the core wire holding plate 19 or the edge of the center conductor connecting terminal plate 17, and the bending deformation is corrected.
There was also a risk that work was delayed.

Therefore, an object of the present invention is to solve the above-mentioned problems, and the workability can be improved by reducing the number of screw members that need to be operated at the time of fixing the outer conductor of the coaxial cable, Further, the present invention provides a coaxial cable fixing bracket excellent in handleability without the possibility that the outer conductor pressing plate will fall off due to excessive loosening of the screw member, and furthermore, the coaxial cable fixing which can easily fix the central conductor of the coaxial cable. It is to provide metal fittings.

[0012]

According to a first aspect of the present invention, there is provided a coaxial cable fixing bracket for fixing a substantially cylindrical outer conductor of a coaxial cable, and a center of the coaxial cable. A central conductor fixing metal fitting for fixing a conductor, and the external conductor fixing metal fitting includes an external conductor connection terminal plate having an external conductor mounting portion for contacting the external conductor, and the external conductor mounting portion. An external conductor pressing plate having an external conductor pressing portion for pressing the external conductor at an opposing position and being fastened to the external conductor connecting terminal plate by a screw member, wherein the external conductor connecting terminal plate and the external The outer conductor is fixed by being clamped with a conductor holding plate, and the center conductor fixing bracket is connected to a center conductor connection terminal plate having a center conductor contact portion for bringing the center conductor into contact with the center conductor contact portion.

According to the above configuration, when the external conductor of the coaxial cable is fixed to the external conductor fixing bracket, the external conductor fixing portion is freely provided between the external conductor holding plate and the external conductor connection terminal plate. First, loosen the screw member that fastens the outer conductor holding plate to the outer conductor connection terminal plate so that a gap that can be inserted and removed is secured, and then, between the outer conductor holding plate and the outer conductor connection terminal plate. It is necessary to retighten the screw member after inserting the external conductor fixing portion into the gap. However, during these operations, only one screw member has to be loosened or re-tightened, and compared to the conventional bracket for coaxial cable, which had to operate two screw members, the operation of the screw members was Such labor is reduced by half.

Also, for example, even if the surface of the substrate on which the fixing bracket for the coaxial cable is mounted is in a vertical upright state or in a downward state, and the screw member is loosened too much by mistake during the fixing work of the coaxial cable. Since one end of the outer conductor pressing plate is always connected to the outer conductor connecting terminal plate by the uneven engagement structure, there is no possibility that the outer conductor pressing plate will fall off.

It is preferable that a concave portion is provided which engages with a protrusion of a peripheral structure to restrict turning in a direction orthogonal to a direction facing the external conductor connection terminal plate. With this configuration, the outer conductor connection terminal plate and the outer conductor holding plate constituting the outer conductor fixing bracket have one end locked or engaged by a simple relative rotation operation in a direction orthogonal to the mutually facing direction. The work can be changed to the release state, and the work of attaching the external conductor connection terminal plate to the substrate or the like can be performed with the external conductor holding plate removed. Further, for example, when the surface of the substrate on which the external conductor fixing bracket is mounted is a vertical surface, the rotation restricting recess provided on the external conductor pressing plate is engaged with the projection of the substrate surface or a surrounding structure. By doing so, the rotation of the outer conductor holding plate in the removal direction is restricted, and the engagement between the outer conductor holding plate and the external conductor connection terminal plate due to careless rotation of the outer conductor holding plate is prevented. be able to.

Preferably, in the center conductor fixing bracket of the above-described coaxial cable fixing bracket, the center conductor connection terminal plate is provided at both ends of the center conductor connection terminal plate so as to abut on both end surfaces of the core wire holding plate. It is preferable that the pair of rotation restricting walls that prevent the rotation of the core wire pressing plate have different protruding lengths. With this configuration, when fixing the center conductor of the coaxial cable to the center conductor fixing bracket, the screw member for tightening the core wire holding plate to the center conductor connection terminal plate is loosened, and the core wire holding plate and the center conductor connection terminal plate are removed. When a gap is secured between the two to allow the center conductor fixing portion to be freely inserted and removed, the gap is in a state of communicating with the external space on the side of the rotation regulating wall having a small protrusion length. Therefore, the insertion of the center conductor into the gap is made possible by inserting the center conductor from the side of the gap.

The side where the presser plate 53 is largely opened can be in a state of communicating with the external space. Therefore, the outer conductor 3b can be inserted into the gap by inserting the outer conductor 3b from the side of the gap. Compared with a conventional coaxial cable fixing bracket inserted from the front of the gap, the coaxial cable can be inserted into the gap. The fixing of the outer conductor 3b of the third 3 is also facilitated, and the workability can be further improved. This is realized by the above-described hook locking structure and the rotation preventing mechanism provided by the uneven locking structure provided at the one end 53b of the outer conductor holding plate.

By engaging the projection 53h with the projection 47 of the surface of the substrate 42 or a structure around it, the turning of the external conductor pressing plate 53 in the unlocking direction is restricted, and the careless turning of the external conductor pressing plate 53 is performed. With this configuration, the engagement between the external conductor holding plate 53 and the external conductor connection terminal plate 51 can be prevented from being disengaged. When the mounting surface of the external conductor fixing bracket 33 is a vertical surface or the like, handling and workability are improved. Can be improved.

In the above embodiment, when fixing the center conductor 3e of the coaxial cable 3 to the center conductor fixing bracket 35, the screw member 65 for tightening the core wire pressing plate 63 to the center conductor connection terminal plate 61 is loosened. Thus, while the rotation restricting wall 61c having a large protruding length is in contact with one side of the center conductor holding portion 63a, the center conductor fixing portion 3f can be freely inserted and removed between the core wire holding plate 63 and the center conductor connection terminal plate 61. A gap of about degree is secured, and the gap is in a state of communicating with the external space on the side of the rotation regulating wall 61b having a small protruding length. Therefore, the insertion of the center conductor 3e into the gap is made possible by inserting the center conductor 3e from the side of the gap. The fixing of the center conductor 3e of the cable 3 is also facilitated, and the workability can be further improved.

In the above-described embodiment, the case where the coaxial cable 3 is connected and fixed in the dome type video camera device 41 is shown. Other than the above, it can be used for fixing a coaxial cable for general use.

Only one connecting to the external conductor connection terminal plate is required. Therefore, as compared with a conventional bracket for coaxial cable, which requires operating two screw members, the labor required for operating the screw members is reduced by half, and workability can be improved.

Further, for example, even if the surface of the substrate on which the fixing bracket for the coaxial cable is mounted is in a vertically upright state or is in a downward state, and the screw member is excessively loosened accidentally during the fixing work of the coaxial cable.

The external conductor connection terminal plate can be attached to the substrate, etc., while the external conductor holding plate is removed, improving workability when attaching the external conductor connection terminal plate. It can also be done. Further, for example, even when the surface of the substrate on which the external conductor fixing bracket is mounted is a vertical surface, the rotation restricting recess provided on the external conductor holding plate is engaged with the projection of the surface of the substrate or a structure around the substrate. By restricting the rotation of the outer conductor holding plate in the removal direction, the inadvertent rotation of the outer conductor holding plate prevents the external conductor holding plate from being disengaged from the external conductor connection terminal plate. When the mounting surface of the external conductor fixing bracket is a vertical surface or the like, handleability and workability can be improved.

Further, when fixing the center conductor of the coaxial cable to the center conductor fixing bracket, the screw member for fastening the core holding plate to the center conductor connecting terminal plate is loosened, and the core holding plate and the center conductor connecting terminal plate are removed. When a gap is secured between the two that allows the center conductor fixing part to be freely inserted and removed, the gap is
