The invention relates to a PE terminal box special for T connection, which includes a terminal block, a wiring terminal, a terminal lug, a fixing mount, a mounting buckle, a terminal cover; a plurality of lateral branch holes are formed at one side of that connecte terminal, the connecting lugs are arranged on the other side of the wiring terminal, the two ends of the connecting lugs are connectedwith the connecting terminal through screws, and the connecting lugs are adopted to connect the PE trunk lines, and the PE trunk lines do not need to be cut off or punctured during the connecting, but the insulating layer is partially stripped off to expose the copper conductor for crimping; At that time of branch wire connection, only the insulate layer is peel off at the end, and the exposed copper conductor penetrates into the branch wire hole and is press-bonded. The connection method has low resistance and can ensure the reliability of grounding. The terminal blocks are press-bonded on the flat steel of the floor at both ends of the terminal terminals through mounting buckles, so that holes need not be punched on the flat steel, and the installation is convenient.
Description
technical field [0001] The invention relates to a connection terminal box, in particular to a special PE terminal box for T connection. Background technique [0002] The T-connection terminal is mainly used for "T"-shaped split line connection when the main cable (trunk line) cannot be cut off in construction and industrial electrical equipment; the PE line is what we usually call the ground wire. In high-rise residential buildings, the PE main line It is connected vertically from the top floor to the underground, and the residents on each floor must be connected to the PE trunk line through the PE branch line. There is no dedicated terminal for connecting the existing user PE branch line to the PE main line. The copper consumption of the wire is large, the connection resistance is large, and the temperature rises, which poses certain safety hazards. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a special PE t...
