The present invention is a connector of the wire protection tube connecting the wire protection tube to the other wire protection tube or to the distribution box to cover the outside of the wire in order to protect the wire during wiring of various electrical works, machine tools, industrial machinery, plant (PLANT) construction, etc. In more detail, the connection protection of the corrugated pipe for wire protection can be achieved quickly and easily, as well as sealing the gap of the joint to prevent foreign material or moisture from entering into the machine from the outside, thereby improving the insulation function. It relates to the connection of electric wire sheath to extend the service life of the device.

When wiring various electric works, industrial automation machines, etc., the wire protection tube is made to connect the wire protection tube made of synthetic resin for wiring the wires of several strands in order to arrange the wires of several strands neatly. Connectors are known.

However, the connector of the conventional wire protection tube is a complicated structure and the structure of the connector consisting of a connector connecting the wire protection tube and the fastener is composed of a relatively complicated structure, and each time the coupling of the wire protection tube to the connector to loosen and tighten the fasteners many uses There was a problem with the inconvenience.

"형의 걸림턱을 형성하고 조임구에는 탄성할절편을 내측으로 오므리기 위한 경사면을 형성하여서됨을 특징으로 한 전선보호관의 연결구가 실용신안등록 제332734호로 등록공고된바 있었다.In order to solve this problem, the wire protection tube formed with a recess and a protrusion for protecting the electric wire with the fitting hole of the fastening hole by screwing the fastener into the threaded portion of the connector which forms the screw pipe for fixing to the distribution box of the mechanical device. In the connector which can be fitted and fixed, the connecting pipe is formed with a plurality of elastic split pieces at regular intervals, but the ends of the elastic split pieces are gradually wider from the outer side to the inner side.

The connector of the wire protector was registered as Utility Model Registration No. 332734, which is characterized by forming a locking jaw of the type and forming an inclined surface for retracting the resilient section into the fastener.

However, such a conventional connector has the advantage of good workability by allowing the wire protection tube to be pushed together with one touch at a time with the fitting hole of the fastener in a state where the fastener is fastened inward to a connector tube having a plurality of elastic segments. On the other hand, the gap between the joint is formed a lot of foreign matter is generated, a lot of moisture is introduced into the mechanical device has a problem that the insulation function is very weak, such as to reduce the life of the mechanical device.

The present invention is to solve the above problems, it is possible to quickly and easily achieve the connection fixing of the corrugated pipe for protecting the wire, and to seal the gap of the joint portion to prevent the inflow of foreign substances or moisture from the outside to the mechanical device insulation function Its purpose is to provide a connector for the wire sheathing tube which can extend the service life of the mechanical device by further improving.

In order to achieve the above object, the present invention is a screw pipe is fastened to the distribution box is formed on one side, the insertion recess is formed in the central stepped jaw, the other end is connected to the plurality of filter protrusions protruding outward;

A connection ring made of a rubber material having a plurality of insertion holes formed therethrough through which the filtering protrusion of the connection fixture is inserted and fixed;

Inserted from the other side of the connection ring insertion hole at one side end is formed with a plurality of insertion protrusions fixed in the inner side and a ring groove is formed on the other outer periphery, the upper and lower folding opening and closing which is a pair of pipes formed with a plurality of recesses and protrusions on the inner periphery ;

A corrugated pipe for protecting wires formed with recesses and protrusions on the outer circumference thereof and fixedly connected by the upper and lower folding openings;

A rubber tube which is wrapped around the outer surface of the pair of upper and lower folding openings by releasing the wound state when one end is inserted and wound around the insertion recess of the connection fixing device step, and the wire protection corrugated pipe is connected and fixed;

The rubber tube is characterized in that it comprises a fastening ring fitted to the ring groove of the upper and lower folding openings.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
