Description

[Detailed Description of the Invention] The present invention relates to a coaxial cable fastener for fixing a coaxial cable to a housing of a series unit or the like.

Conventionally, when attaching a coaxial cable to a series unit or the like installed indoors, a coaxial cable 2 is fixed to the side surface of a housing 1 with screws using an ohm band 3, as shown in FIG.

That is, as shown in FIG. 2, the coating of the coaxial cable 2 is stripped, the braided portion 4 serving as the outer conductor is folded back, and the core wire 5 is exposed, and the braided portion 4 is removed as shown in FIG. It is held down and fixed with the screws of the ohm band 3, and is also grounded to the casing 1.

However, in the conventional mounting structure using such an ohm band 4, the cut end of the braided portion 4 of the folded coaxial cable 2 protrudes from the ohm band 3 as shown in FIG. 1, resulting in an unsightly appearance. Although the appearance is improved by cutting the edges evenly, there is a problem in that the construction is time consuming.

In addition, the cut end is cut short so that it does not protrude beyond the ohmic band, but if the folded braided portion is too short, there is a risk that the ground connection will be uncertain when pressed with the ohmic band.

The present invention was developed in view of these conventional problems, and is a coaxial cable fixing system that enables reliable grounding connection by fixing the cable and also improves the appearance without requiring much effort in construction. The purpose is to provide metal fittings.

In order to achieve this purpose, the present invention has a structure in which a skirt is provided on one side of the Ω-shaped fastener with fixing screw insertion holes at both ends to cover at least the braided part that becomes the outer conductor of the coaxial cable. This is what I did.

Hereinafter, embodiments of the present invention will be described based on the drawings.

FIG. 3 is a plan view showing an embodiment of the present invention, FIG. 4 is a front view, and FIG. 5 is a side view.

First, to explain the structure, the coaxial cable fastener of the present invention has a fastening part 10 formed in an Ω shape with screw insertion holes 11 on both sides, and a skirt part 12 is integrated into one piece of the fastening part 10. It has been extended to As is clear from FIG. 4, the skirt portion 12 has an inverted U-shaped end surface that protrudes upward from the Ω-shaped stopper portion 10, and the lower end of the skirt portion 12, which is the U-shaped end, is connected to the stopper. It extends downward from the section 10.

Further, as is clear from the side view of FIG. 5, the continuous portion from the stopper part 10 to the skirt part 12 is continuously stepped with an inclined surface 13.

In the coaxial cable stopper of the present invention, the stopper part 10 and the skirt part 12 can be integrally formed by pressing a sheet metal.

Furthermore, as is clear from FIG. 3, a through hole 14 is provided in the holding part that is the center of the stopper part 10, and this through hole 14 allows the coaxial cable to pass through when the coaxial cable is fixed to the housing. By allowing the braided portion serving as an external conductor to be soldered through the through hole 14, the grounding connection of the braided portion to the casing can be reliably performed.

FIG. 6 is an explanatory diagram showing how the coaxial cable fastener of the present invention shown in FIGS. 3 to 5 is attached to the housing, and as shown in FIG. The coaxial cable 2 is fixed to the housing 1 by creating a section by peeling the coaxial cable, and fixing the coaxial cable 2 to the housing 1 with screws using the screw insertion holes 11 provided at both ends of the stopper part 10 of the coaxial cable stopper 15. In addition, the folded braided portion 4, which becomes an external conductor, is connected to ground. At this time,
The folded braided part 4 is attached to the coaxial cable stopper 1
As shown in the figure, the skirt portion 12 of No. 5 covers the braided portion, eliminating the need for work such as trimming the braided portion. The appearance of the coaxial cable 2 connected and fixed to the body 1 with the coaxial cable stopper 15 can be improved, and the finish of the construction work can be made neat.

Next, to explain the effects of the present invention, a skirt part that covers at least the braided part of the coaxial cable is installed on one side of the stopper part, which is formed in an Ω shape and has fixing screw insertion holes at both ends. Therefore, the braided part of the coaxial cable that protrudes from the Ω-shaped stopper part is covered by the skirt part and is not exposed to the outside, and the exposed braided part does not deteriorate the appearance, so there is no need for trimming. Then,
In addition, the length of the braided part exposed by peeling the cable can be made longer, and by providing a through hole in the holding part that is the center part of the stopper, the coaxial cable can be passed through the through hole to the outside of the coaxial cable. The braided portion serving as a conductor can be soldered, and the grounding connection of the braided portion to the casing can be reliably performed.
