The first coupling member 400 protrudes on the outer side of each of the guide ribs 410 protruding from the bottom surface of the bottom cover 320 and guide ribs 410 to guide the insertion into the open upper portion of the housing 210. The engaging protrusion 420 and the elastic piece 430 which is elastically restored when the external force is removed and is elastically opened in the outward direction when the external force is generated by cutting a portion of the side wall of the housing 210 in contact with the locking protrusion 420 and the It is formed in the inner surface of the elastic piece 430 is formed of a locking groove 440 for receiving the locking projection 420 when the elastic restoration.

Accordingly, the guide rib 410 of the bottom cover 320 is inserted into the upper portion of the housing 210 and the elastic piece 430 is opened by the locking protrusion 420, and the locking protrusion 420 is locked. The elastic piece 430 is elastically restored while being received in the groove 440.

Thus, the locking protrusion 420 is caught by the lower edge of the locking groove 440, the housing 210 and the bottom cover 320 is coupled.

Of course, when the user forcibly opens the elastic piece 430 to the outside, the locking protrusion 420 is separated from the locking groove 440, the housing 210 and the bottom cover 320 is separated.

At this time, the bottom cover 320 forms a stopper piece 450 spaced apart from the guide rib 410 on the lower surface.

The stopper piece 450 restricts the spreading of the outer side of the elastic piece 430 to prevent separation of the housing 210 and the bottom cover 320.

Meanwhile, as shown in FIGS. 4A and 4B, the bottom cover 320 and the upper cover 330 are detachably coupled by the second coupling member 500 formed at the connection portion.

The second coupling member 500 cuts a portion of the side wall of the coupling protrusion 510 protruding from the outer surface of the bottom cover 320 and the upper cover 330 in contact with the coupling protrusion 510 in the outward direction when an external force is generated. The locking projection 530 is formed at the end of the inner surface of the coupling piece 520 and elastic coupling when the external force is removed and the elastic force is removed. Is made of.

Therefore, the bottom cover 320 is inserted into the upper cover 330 and at the same time the engaging projection 510 pushes the locking projection 530 protruding to the inner bottom of the engaging piece 520 to the outside, the engaging piece 520 is When the coupling protrusion 510 passes through the locking protrusion 530, the elastic piece 430 is elastically restored.

Thus, the coupling protrusion 510 is engaged with the locking protrusion 530 and the bottom cover 320 and the upper cover 330 are coupled to each other.

Of course, when the user forcibly opens the coupling piece 520 to the outside, as the coupling protrusion 510 is separated from the locking protrusion 530, the bottom cover 320 and the upper cover 330 are separated.

In this case, the bottom cover 320 protrudes and forms an insertion protrusion 540 on the outer surface, and the upper cover 330 inserts the insertion protrusion 540 to set the correct position when assembling the bottom cover 320. The insertion groove 550 is formed on the inner side surface thereof.

Thus, as the insertion protrusion 540 is inserted into the insertion groove 550, the bottom cover 320 and the upper cover 330 are easily assembled to the correct position.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and those skilled in the art to which the art belongs can make various modifications and other equivalent embodiments therefrom.
