Description

Bypass connector {BYPASS CONNECTER}

The present invention relates to a bypass connector.

In general, power cables are manufactured to a predetermined length due to limitations in manufacturing or transportation, and then are wound around a bobbin assembly and transported to a power cable installation site.

When constructing a building, all power supply is connected between the conduit embedded in the concrete ceiling of each floor and the outlet box, and begins through a metal pipe or PVC pipe (hereinafter collectively referred to as a cable) embedded in the concrete ceiling. After constructing cables from the distribution board on each floor and embedding them in concrete, outlet boxes are installed at the locations of the relevant devices, and then flexible pipes are extended and connected to lighting fixtures or outlets to perform wiring work for lights and heating devices inside the building.

Here, a cable connection material is used as a means to connect multiple cables to a transformer that receives electricity from a high-voltage electric cable, converts it to low voltage, and supplies it to each customer, or to a switch installed between installed transformers. In order to connect multiple cables, Korean Patent Publication No. 10-2001-0103874 also discloses a cable connection device for connecting cables of different thicknesses.

However, in this type of wiring work, the conduit connecting each light fixture and outlet is buried in the cement layer or fixed in an exposed state during construction, so if the wiring work needs to be redone due to a change in use or structure of the building, the existing Since the wiring must be re-routed or additionally installed, the work is not only cumbersome and difficult, but also takes a long time.

To prevent this, a bypass path is created in the equipment being repaired and the faulty or repaired section is repaired while the current is on. Conventional connectors to secure the bypass path fix the contact member by screwing it or attach it to a divided external housing. After assembly, the contact member is fixed by assembling the external housing, which has the disadvantage of having a large number of parts and a complicated structure.

In addition, the receptacle connector combined with the contact member of a conventional cable connector is fixed by screwing, which has the disadvantage of lengthening the working time.

One embodiment of the present invention seeks to provide a bypass connector that can easily secure the electrical conduction state of the contact member of the cable connector and the receptacle connector and shorten the work time in order to overcome the problems of the prior art.

According to one aspect of the present invention, a cable connector electrically connected to one end of the cable; and a receptacle connector connected to the other side of the cable connector. It includes, wherein the cable connector includes: a contact member coupled to one end of the cable and having a locking groove; a contact member fixing member through which the contact member is inserted and has a fixing protrusion formed toward the center to be coupled to the locking groove; an insulating housing in which the contact member fixing member is seated; and an outer housing that surrounds the insulating housing and is coupled to the cable. It includes a receptacle connector, the receptacle body including a hollow annular side wall and a contact coupling portion coupled to the contact member of the cable connector along the axial direction, and having a fixing pin protruding on one side in the radial direction; A coupling nut rotatably coupled to the outer surface of the receptacle body and having a pin fixing groove inserted into the fixing pin to limit rotation of the receptacle body; a plurality of plug fixing balls each provided in a plurality of holes formed on an inner surface of the receptacle body; and a ring-shaped cap coupled to one end of the receptacle body. Includes.

The insulating housing insulates the contact member from the external housing and fixes the contact member.

A ball seating groove for coupling is formed at an end portion of the outer housing in the coupling direction, and a stopper is formed adjacent to the ball seating groove to limit the coupling length.

A clamp portion cut along the length direction is formed at a portion where the external housing is coupled to the cable to secure the cable.

The insulating housing is formed with an extension whose diameter gradually increases in the direction in which the cable is coupled.

It further includes a spring provided between the receptacle body and the coupling nut to provide elasticity.

The coupling nut is movable along the axial direction when the fixing pin is detached from the pin fixing groove of the receptacle body based on the axial direction.

The cable connector is coupled to the receptacle connector so that the plug fixing ball is seated in the ball seating groove.

According to the present invention, the following effects are achieved.

First, it is easy to assemble with a fitting structure that uses fixing protrusions and grooves.

Second, the service life can be extended because the position of the contact point does not change even after repeated use.

Third, the cable connector and receptacle connector have a fitting structure rather than a screw fastening structure, making it easy to combine.

Fourth, manufacturing costs can be reduced due to the small number of parts and simple structure.

In addition, the ball support portion 224 of the coupling nut 220 receives the elasticity of the spring 250 when the fixing pin 216 is removed from the pin fixing groove 222, so that the coupling nut 220 is connected to the cable connector 100. ) will move to the side.

The ball separation prevention portion 226 of the coupling nut 220 prevents the plug fixing ball 230 from being separated from the coupling nut 220 when the cable connector 100 is disconnected.

As shown in FIG. 3, the coupling nut 220 moves along the axial direction when the fixing pin 216 is positioned in the L-shaped pin fixing groove 222 of the receptacle body 210 based on the axial direction. Movement and rotation are restricted. After the fixing pin 216 is removed from the pin fixing groove 222, the coupling nut 220 can move and rotate based on the axial direction.

The coupling nut 220 is limited in axial movement from the receptacle body 210 by the annular cap 240 coupled to one end of the receptacle body 210. And, when the cable connector 100 is coupled to the receptacle connector 200, the movement of the coupling nut 220 from the receptacle body 210 is restricted by the stopper 148 of the external housing 140.

A plurality of plug fixing balls 230 are provided in each of a plurality of holes formed on the inner surface of the receptacle body 210. A plurality of plug fixing balls 230 are spaced apart from each other on the inner surface of the receptacle body 210.
