A branch sleeve for a connection of a low voltage electric wire is provided to expand a life span and improve working efficiency by blocking inflow of foreign substances. A couple of sleeve bodies are non-conductors divided into upper and lower parts which wrap an outer plane of a main wire. A conductive tube electrically connected to the main wire is hung by protrusions of both ends. A couple of insertion grooves having a couple of screw units are formed on a lower part of the conductive tube. A plurality of coupling grooves are formed on an outer circumferential plane of the sleeve body. A sleeve coupling unit(20) wraps the coupling groove of the outer circumferential plane of the sleeve body, and has a ring chain coupling ring having coupling plates at both ends. A coupling bar having a plurality of bolt bars which are fixed by nuts is formed by penetrating a coupling hole of the coupling plate of the coupling ring. A conducting connection unit(30) has a bar shape which is screw-connected to insertion grooves of the sleeve bodies. The conducting connection unit(30) is electrically connected to the conductive tube by forming a conductive pin from an inner central part to an upper part. A connection groove is formed inwardly on a lower center of the conductive pin. A screw coupling hole is formed on a lower side of the connection groove. A sub wire(60) is formed on a front end of a conducting screw(40). The conducting screw(40) is fixed on the screw coupling hole of the conducting connection unit(30). A protection tube(50) is connected to the sub wire(60). An upper part of the protection tube(50) covers a lower part of an outer circumferential plane of the conducting screw(40). |
