At this time, the connection screw 125 makes a surface contact such that an end thereof protrudes into the insertion hole 133 through the spiral hole 131 and is connected to the connection ring 137.

이에 따라, 상기 절연덮개(110)와 접속구(120)는 저압전선(T)에 견고한 연결관계를 이루게 된다.Accordingly, the insulating cover 110 and the connector 120 make a strong connection to the low-voltage wire (T).

이후, 상기 연결구(130)의 삽입공(133)에 인하선(L)을 삽입한 후, 결합홀(139)에 고정나사(138)를 체결한다. Then, after inserting the lowering line (L) in the insertion hole 133 of the connector 130, and fastening the fixing screw 138 to the coupling hole (139).

이에 따라, 상기 고정나사(138)는 그 단부가 인하선(L)의 피복(P)을 가압하여 인하선(L)이 연결구(130)에 견고히 연결고정되도록 한다.Accordingly, the fixing screw 138 presses the cover P of the lowering line L so that the lowering line L is firmly connected and fixed to the connector 130.

이에, 본 발명의 저압전선 접속용 분기슬리브는 저압전선에 분기슬리브를 견고하게 연결고정하여 어떠한 기후적인 변화에도 분기슬리브가 저압전선에서 탈거되는 것을 미연에 방지할 수 있도록 한다.Thus, the branch sleeve for connecting the low-voltage wire of the present invention firmly connects the branch sleeve to the low-voltage wire to prevent the branch sleeve from being removed from the low-voltage wire in any climatic change.
