Hereinafter, a structure of an electrical wire connector according to an embodiment of the present invention will be described with reference to the accompanying drawings.

In the following description, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. The terms used in the following description are terms set in consideration of functions in the present invention. These terms may vary depending on the intention or custom of the producer producing the product, and definitions of the terms should be based on the contents throughout the specification.

(Example)

1 to 4, an electrical wire connector 100 according to the present invention includes a wire tube assembly 120 in which a wire tube 150 for covering and protecting an electric wire is assembled, And a switch cover assembly 110 which is inserted and fixed by a switch cover 140 of the switch cover 160 is integrally formed.

The switch cover assembly 110 is formed as a circular tube and has a bushing fastening band 111 bent inward to prevent the wire protecting bushing 130 from being inserted and inserted into the switch cover 140, At least two protrusions are formed on the outer periphery.

The wire protecting bushing 130 is preferably made of a PVC material for protecting the electric wire.

The wire protecting bushing fastening band 111 may be formed by cutting a concave portion at the tip of the lock / unlock button 113, but it may be formed by cutting the other direction concave portion as necessary.

At the outer periphery, a locking / releasing button 113 extending outwardly from the recess is provided at both ends. At this time, the locking / releasing button 113 is pushed inward when inserted into the switch cover, and the locking protrusion 114 is formed to prevent the switch cover from being pulled out due to the elastic force.

The slip prevention protrusion 114 is preferably embossed inwardly from the inside of the pipe. This is to prevent the slip prevention protrusion from being broken and forcibly separated when the lock / unlock button 113 is pulled out without pressing the lock / unlock button 113 while assembled to the switch cover 140.

That is, when the connector is pulled out by an external force at the time of use, the protruding protrusion, as described above, is pushed out by the force when the connector is pulled out There is a problem that the switch cover can not be supported properly by the phenomenon of being bent or bent.

However, when the connector is pulled by the steel material, the stopper protrusion 114 of the present invention is supported on both sides so that deformation of the stopper protrusion does not occur, It is possible to prevent separation phenomenon before pressing the / cancel button.

In addition, when the lock / unlock button 113 is formed to be bent and pulled by the steel material, the force due to the tension action is reversely applied, thereby preventing the lock / unlock button 113 from falling further.

It is preferable that the slip prevention protrusion 114 is formed so as to be interlocked with the lock / release button 113.

On the other hand, the lock / unlock button 113 is configured to have a curved surface, and the gap between the cutout portion of the pipe and the outer surface of the pipe is kept to a minimum, so as to prevent tangling between the other connector and the conduit.

If the gap or gap is not minimized, when the product is packed or packed, mutual entangled products may cause breakage and defect rate. However, the lock / unlock button of the present invention minimizes the gap and interval, Tangling is prevented.

The wire and the assembly part 120 are provided with a tension bead 121 for increasing a tensile force in the center and a wire for holding a screw-shaped conduit for preventing the conduit 150 from being assembled The locking protrusion 122 is formed in a screw shape.

At least two or more tension beads 121 are provided on the outer circumferences of the switch cover assembly 110 and the conduit assembly 120, and the tension beads may protrude outward from the inside.

This is because the tension bead is formed outwardly of the inner bead of embossed tension beads, and deformation of the product can be prevented.

That is, in the heat treatment process of the product or other processes, the shape of the circular pipe may be deformed or twisted due to heat or external load. However, by constructing the tension bead to protrude to the outside, Can be minimized.

The switch cover assembly 110 may further include a wire protecting bushing 130 for protecting the wire.

An operation state of the electric wiring connector 100 having the above-described configuration will be described.

First, in order to engage the conduit 150 covering the wire with the conduit assembly 120, when the conduit is pushed in at the rear end of the conduit assembly, the wire clips 122 formed therein expand to the outside, The ground wire conduit stopper is restored to its original state and the clad portion is prevented from being pushed out.

In addition, when the conduit is made of a corrugated pipe or a screw, the connector and the conduit assembly can be easily inserted and fixed by rotating the conduit assembly in one direction through the conduit.

When the conduit 150 is assembled as described above, the electrical wiring connector 100 may be coupled to a wiring box installed in the building wall.

When the connector 100 is coupled with the switch cover 140 of the power distribution box by hand and the switch cover assembly is pushed in, the slip prevention protrusion 114 is pushed inward. At this time, the lock / 113) is also pushed inward.

When the slip prevention protrusion 114 passes through the hole of the switch cover, the switch cover 140 is caught by the step 112 formed on the outer periphery of the switch cover 140 so as to be prevented from being inserted into the switch cover 140, The locking protrusion and the lock / unlock button are returned to their original positions by the tension force, and are mounted on the surface of the switch cover 140 by the locking protrusion and the step 112.

As described above, the connector 100 of the present invention allows the conduit to be easily installed in the switchboard.

If repair is required due to breakage of the conduit or breakage of the connector, the connector connected to the switchboard may be separated by the following method.

When the locking / releasing button 113 provided on the switch cover assembly 110 is pressed, the slip prevention protrusion 114 is pushed inward and the slipping prevention protrusion is completely separated from the hole of the switch cover 140 , Remove it by hand and remove it from the switch cover, and release the lock / unlock button.

The connector thus separated may be replaced and repaired and assembled again by the above-described assembling method.

As described above, since the conduit pipe can be efficiently assembled and disassembled into the discharge pipe by using the conduit connector, the workability due to the distribution can be improved, and the time required for the distribution work can be shortened to reduce the construction cost.
