JP2503676Y2 - Adapter for fitting connector used between equipment and cable with fitting connector - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a fitting connector adapter used for connecting a device to a fitting connector in a cable television (CATV) system or the like.

[Prior Art] A fitting connector used in a CATV system or the like has male and female connector coupling parts, and usually a cable side is a male type and a device side such as an amplifier and a distributor has a female type.

The female side of the device side has a female screw directly on the device housing, and when connecting to the male side of the cable side, the shell part of the fitting connector with the male screw is first screwed into the device housing. By connecting them, the parts of the connector and the cable are sequentially assembled into the center contact, insulator, clamp, tightening nut, gasket, and tightening nut.

[Problems to be solved by the invention] However, when laying a CATV cable, there is a lot of work on the pole, and after installing the equipment, connecting the connector shell to the equipment, inserting the cable, and assembling the connector parts takes time. It takes a lot of work and the workability is not good.

In addition, since the connectors and the cables are sequentially assembled, it may not be possible to sufficiently confirm whether the connection between the connector and the cable is securely assembled, resulting in insufficient connection.

Further, when the device is replaced, the connector and the cable must be disassembled by the reverse procedure of the assembling so that the structure cannot be replaced, which requires a very complicated procedure.

The object of the present invention is to solve the above-mentioned drawbacks of the conventional construction method, to install the connector in the cable and to connect it to the device separately, with good workability, and to confirm the connection between the connector and the cable. An object is to provide an adapter for a fitting connector used between a highly expensive device and a cable with a fitting connector.

[Means and Actions for Solving the Problem] The gist of the present invention is composed of a male coupling portion coupled to the device side and a female coupling portion coupled to a male fitting connector attached to a cable end. The male coupling portion has an outer conductor having a male screw at one end side for insertion coupling to a female screw provided on the device side, a center conductor projecting outward from the outer conductor at the one end side, A first insulator and a first O-ring that insulate and support the central conductor and the outer conductor, and a tubular portion is formed on the central conductor on the other end side. The tubular portion and the outer conductor A device having a second insulator that insulates and supports the outer conductor, a snap ring that rotatably couples the outer side of the outer conductor and an inner side of the cap nut that serves as the male coupling portion, and a second O-ring. Case with fitting connector It is in the adapter for the fitting connector used between the bulls,
The connector can be incorporated into the cable and connected to the equipment separately, and the workability and reliability are greatly improved without twisting the cable.

[Embodiment] FIG. 1 shows a partial vertical sectional view of an embodiment of an adapter for a fitting connector used between cables with a fitting connector of the present invention.

This product is a high-frequency coaxial cable of the Japan Electronic Machinery Manufacturers Association standard.
C14 type connector "is a fitting connector adapter having a male connector coupling portion and a female connector coupling portion, in which the female coupling portion is connected to the outer conductor of the male coupling portion via a snap ring 3. It has a possible cap nut 1 structure.

That is, the male coupling portion has a male outer conductor 2 having one end having a male screw for insertion coupling, a center conductor 4 projecting outward from the outer conductor 2, and a portion between the center conductor 4 and the outer conductor 2. Having insulators 6 and 7 and O-rings 10 and 11 for insulating and supporting, and an insulator for insulating and supporting the cylindrical portion 12 of the central conductor 4 at the other end and between the cylindrical portion 12 and the outer conductor 5 has a snap ring 3 and an O-ring 8 which are connected to the outside of the outer conductor 2 and the inside of the cap nut 1 in order to rotatably support the rotary cap nut 1 of the female coupling portion.

If you want to connect the device to the connector built into the cable beforehand, insert the male connector of the adapter for the fitting connector of the present invention into the device and connect it with a screw, then connect the cable connector to the adapter for the fitting connector. By inserting into the female connector and rotating the cap nut, it is not necessary to rotate the cable connector, and the connection can be made without twisting the cable.

[Effects of the Invention] By using the fitting connector adapter used between the device of the present invention and the cable with a fitting connector, the connector can be assembled into the cable first, and it can also be assembled on the ground, which improves workability. Get better Furthermore, the connection between the cable and the connector can be sufficiently confirmed without twisting the cable, and the reliability is improved.

For maintenance and repair, the device and cable connector can be easily separated and assembled by the adapter of the present invention, and the device and cable can be easily maintained and repaired.
