Description

[Detailed description of the invention] The present invention relates to the invention of an antenna power feeding unit mechanism, which allows the connection and handling of the power feeding unit to be easily and quickly performed in a TV receiving antenna, etc., and also allows for simple and accurate assembly of the power feeding unit to the arm. It was designed to be obtained.

It is well known that in a TV receiving antenna, etc., it is necessary to feed power to the antenna using a cable, and regarding the power feeding part between each line end of such a cable and the antenna element, each line end This is done by connecting and fixing it to a predetermined terminal using screws or the like. However, in such conventional power feeding parts, the operation of fixing the wire ends with the screws etc. is complicated, and this type of feeding part connection is especially difficult when working at high places such as when working on an antenna erected on a rooftop. Therefore, it is generally a one-handed operation, and work such as fixing and releasing the ends of screwed wires at high places is extremely troublesome in practice and has the disadvantage of increasing man-hours. .

The present invention was devised after consideration to eliminate the disadvantages of the conventional ones as described above, and it is possible to connect or disconnect the cable end in the antenna feeding section with a single touch. This makes it possible to easily and accurately attach the arm to the arm.

That is, to explain a specific embodiment of the present invention shown in the accompanying drawings, a power feeding section is formed with elements 4, 4 arranged on both sides of the arm 7 of the antenna A as shown in FIG. However,
Such a power supply section is shown in Fig. 1 from Fig. 2 and Fig. 9.
The main components are a power feeding section main body 1 as shown in FIG. 3 and a fitting section body 2 as shown in FIGS. 2 to 8. The fitting part 10, which will be described later, is provided with a protruding piece 13 that is inserted into a hole in the arm 7 for positioning, and the fitting part body 2 is provided below the middle of the protruding piece 13.
An insertion hole 12 is formed for receiving the insertion part 1.
L-shaped bent terminal pieces 5 with one end side 5a positioned inside each terminal piece 1 are mounted, and the other end side 5b of the terminal piece 5 is provided oppositely on both sides of the insertion hole 12. However, the above-mentioned insertion part body 2 has a receiving part 21 for the cable 6 vertically arranged in the middle part thereof, and a seat part 20 of the shaft part 24 is formed in the upper part thereof. A wire end receiving portion 22 is provided oppositely with a gap 20b formed therebetween, and a guide portion 23 for the other end side 5b of the bent terminal piece 5 as described above is formed adjacent to the wire end receiving portion 22. The wire end portions 6a and 6b of the cable 6 are pressed into contact with the other end side 5b of each bent terminal piece 5 while being received in the receiving portion 22.

In addition, in the illustrated one, the insertion part body 2 as described above is used.
The cap 3 inserted into the cable 6 as shown in FIG. A joint 17 is provided in a ring,
The upper opening of the cap 3 is received and engaged under waterproof conditions. Further, a seat portion 27 is integrally formed at the lower end of the insertion portion body 2, and the crimp portion 2 is connected to the seat portion 27 via a thin flexible portion 28.
6 are connected in series, and the cable 6 as described above
can be set as described above by appropriately inhibiting. In the present invention, an arm fitting part 10 for receiving the arm 7 orthogonally is formed between each insertion part 11 of the power supply main body 1 as described above,
Further, a locking protrusion 25 is provided around the shaft portion 24, and as shown in FIG.
A mounting hole 19 communicating with the insertion hole 12 is formed at the center of the arm fitting part 10, and the shaft part 24 Another mounting hole 29 that matches the mounting hole 19 is formed in the mounting hole 19 .

To explain the operation of the device according to the present invention as described above, as shown in FIG.
By folding back the insertion part body 2 at the gap 20b and receiving them in the wire end receiving parts 22, the insertion part body 2 is inserted into the insertion hole 12 of the power supply part main body 1. Therefore, the other end side 5b of each bent terminal piece 5 is press-contacted to the outside of the wire end portions 6a, 6b, respectively, to form a connected state, and the wire end portions bent and inserted can be fixed. In other words, by simply inserting the insertion part body 2, connection and attachment can be easily achieved without requiring a conventional holding screw or the like. Furthermore, by removing the insertion part body 2, the above-mentioned connection and attachment can be easily released, and in any case, the connection and attachment can be made and released with just a one-touch attachment/detachment operation, and the cable 6 is connected to the element member 4 and can be disconnected from the power supply unit main body 1.
The arm 7 is fitted into the fitting part 10 of the arm 7, and screws or the like are inserted into the mounting holes 19 and 29, thereby easily and accurately assembling the arm 7, the power feeding part main body 1, and the insertion part body 2. I can do it.

According to the present invention as explained above, it is possible to achieve connection and disengagement in this type of antenna power feeding section in a single touch by simply attaching and detaching the insertion section body 2, so that it is possible to realize the connection and disengagement in this kind of antenna power feeding section simply by simply attaching and detaching the insertion section body 2. This can significantly facilitate the handling of the power feeding part when working at high places in antennas, and moreover, the wire end part 6
Since the other end 5b of the terminal piece 5 is crimped to a and 6b over a considerable length range, the connection and fastening relationship is extremely stable. It can be easily and accurately assembled by using the holes 19 and 29, and has the advantage that the arm and the element 7 can be attached compactly, and is a highly effective device in practical use.
