In order to achieve the above object, the present invention provides a joint for a cable raceway for connecting raceways made of '┕┙' -shaped panels each having a wire or a cable inside thereof and a guide formed on both sides thereof, The joint is composed of a joint body in the shape of a circle and a plurality of projections formed on a bottom surface of the body, the joint being inserted into the raceway through a guide of the raceway, And a joint for a cable raceway is provided.

In the present invention, a stopper is further provided at the center of the bottom surface of the bottom surface of the joint body to limit the insertion length of the joint. The stopper serves to prevent the body from being excessively inserted into the raceway, and a seating groove on which a stopper is seated may be formed on one side of the bottom surface of the raceway. Therefore, when the operator inserts the joint until the joint is fixed by the stopper simply, the work is completed and the work time is advantageously reduced.

In the present invention, bolt holes for bolt fastening are formed on both sides of the bottom surface of the body. The bolt hole is intended to fix the joint more firmly by tightening the bolt when the interference force by the projection is weakened.

The present invention is characterized in that the bottom surface of the raceway is provided with a striking portion for forming a hole for attaching the equipment to the raceway. When it is necessary to fix the luminaire to the raceway, it is advantageous to fix the luminaire to the bottom of the raceway by using a bolt or the like after applying the external force to the rim to remove the rim.

The joint of the present invention may be formed into a straight, elbow or tee shape. And thus can be manufactured in various shapes.

According to the cable raceway joint of the present invention, since the raceway can be easily connected using a joint, the construction is simplified, the construction period is shortened, and the cost is reduced.

Further, it has a structure that can be detached and attached to the raceway by interference with protrusions formed on the joint.

In addition, a stopper is formed at the outer center portion of the lower end to prevent excessive coupling.

As shown in the drawing, according to the present invention, there is provided a 'R "-shaped raceway 100 capable of accommodating electric wires or cables therein, and a straight joint (not shown) for connecting the raceways 100 having a predetermined length to each other 200).

The raceway 100 is formed by a body 110 having a shape of '┕┙' shape. A guide 111 is formed on both upper ends of the body 110 so that a joint can be inserted into the raceway 100 without interference. The flat portion of the body 110 forms a bottom surface 120.

The joint 200 includes a joint body 210 having a rivet shape to be inserted into the guide 111 inwardly and a bottom surface 220 forming a plane portion of the joint body 210, And a pair of bolt holes 223 which are formed so as to be fastened with a bolt if necessary. The bolt holes 223 are formed at the center of the bottom surface of the bottom surface, do. The protrusion 221 is formed so as to protrude downward by punching the bottom surface 220. The stopper 222 is formed so as to protrude below the bottom surface 120 by cutting and bending a part of the bottom surface.

The bolt holes 223 form pairs on both sides, but may not be necessary since they are constrained by the projections. However, it can be used effectively when it is difficult to get rid of it due to manufacturing or other reasons.

The stopper 222 protrudes from the bottom surface of the bottom surface 220 of the joint, and is formed approximately at the center of the joint 200. The reason for forming the stopper 222 at the center is to allow both raceways 100 to be inserted in the same manner. The stopper 222 also functions to prevent the joint 200 from being excessively inserted into the raceway. When the joint 200 is inserted into the raceway 100 for engagement, the insertion length of the joint 200 can not be determined without the stopper. Thus, the stopper 222 determines the length of the joint 200 to be inserted into the raceway 100.

In addition, since the operator simply pushes the stopper 222 until the stopper 222 is stopped, the time required for the operation is shortened, and the function of facilitating the operation is also performed.

A groove 121 in which the stopper 222 is seated is formed at one end of the bottom surface 120 of the raceway. The stopper 222 is inserted into the seating groove by forming the seating groove 121 so that no gap is formed in the coupling surface between the raceway 100 and the raceway 100. [
