Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention secures some connector seats protruding from a coaxial cable device as spares, and screws them into the connector seats to prevent leakage of electricity. The present invention relates to a terminator (resistor) to be attached and used.

[0002]

2. Description of the Related Art The structure is such that a general tool such as a spanner can be freely detached from a connector seat, so that an outsider may use the connector seat without permission.

[0003] There is no structure that prevents such a possibility in advance, and the present invention has been made by focusing on this point.

[0004]

Means for Solving the Problems A terminator body provided with a specially shaped locking portion for a dedicated tool on the distal end surface and screwed into a connector seat protruding from a coaxial cable device, and an inner side of the terminator body The terminal frame is rotatably mounted on the terminal frame. The terminal frame has a jacket frame having substantially the same length as that of the terminal frame. A configuration in which a connection ring having a tapered edge on its outer peripheral surface is engaged with a connection ring, and a locking groove that engages with the connection ring by utilizing the elasticity of the connection ring is provided on the inner peripheral surface of the jacket frame. And

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows an embodiment of a terminator for a connector seat in a coaxial cable device according to the present invention.
FIG. 2 is a partially cut-away side view showing a state where the apparatus is attached to an apparatus, and FIG. 2 is a front view.

In FIG. 1, reference numeral 1 denotes a main body of a terminator A. The main body 1 has a female screw portion 3 on a connector seat 2 protruding from a coaxial cable device B, and surrounds the female screw portion 3 on the outer peripheral surface. The engaging groove 4 is provided as described above, and a special tool 6
In which a specially shaped locking portion 7 is formed.

[0007] In the embodiment, the deformed locking portion 7 is constituted by a partially circular recessed portion provided on the distal end face 5 as shown in the figure. obtain. Here, the irregular locking portion is, for example,
It means a form in which a general tool such as a plus groove or a minus groove is used.

The connecting groove 8 of the terminator main body 1 is engaged with a connection ring 8 of a partially circular shape by utilizing its elasticity, and the connection ring 8 is engaged with the female screw from the distal end face 5 side of the terminator main body 1. A tapered edge 9 gradually expanding in a base side direction provided with the portion 3 is provided on an outer peripheral surface thereof, and the tapered edge 9 is engaged with the engagement groove 4 so as to protrude from the engagement groove 4. .

Reference numeral 10 denotes a jacket frame formed of a cylindrical body having substantially the same length as the terminator main body 1.
And a connecting ring 8 attached to the engaging groove 4 by utilizing the tapered edge 9 and elasticity to engage with the locking groove 11 so as to be rotatable with the terminator body 1. Assembled.

After the main body 1 of the terminator is screwed into the device B, the jacket frame 10 is pressed in the direction of the device B so as to be arranged outside the main body 1 to assemble the casing frame 10 with the main body 1 of the terminator. After attaching them in advance, the terminal unit A may be attached to the device B by screwing to the receiving seat 2 using the modified locking part 7.

The reason why the peripheral surface on the side of the distal end surface 5 of the main body 1 is made circular is that it is difficult to grip with a general tool or the like. Further, the tip of the main body 1 may be slightly protruded from the jacket frame 10, but it should be so small that it is difficult to rotate the terminator main body 1 with a general tool.

[0012]

The present invention has the configuration described above,
It is possible to provide a terminator that cannot be removed from the connector seat unless a special tool is used, and it is possible to prevent the connector seat from being used without permission by removing the terminator. Further, according to the present invention, it is possible to assemble the jacket frame by simply pressing the terminal device main body screwed to the device.

Claims (1)

(57) [Claims] 1. A terminator main body which is provided with a specially shaped locking portion for a dedicated tool on a distal end surface thereof and is screwed into a connector seat protruding from a coaxial cable device, and is rotatable inside the terminator main body. The terminal device body is formed of a jacket frame having substantially the same length as the terminal device body, and a tapered edge that gradually expands from the distal end surface in the direction of the coaxial cable device is formed in an engagement groove provided on the peripheral side of the terminal device body. A coaxial cable device, wherein a notch-shaped connection ring provided on the surface is engaged, and a locking groove for engaging with the connection ring is provided on the inner peripheral surface of the jacket frame by utilizing the elasticity of the connection ring.
