In order to which to conducting wire, there are enough crossing space of lines and final conducting wire is enable to be pressed in lead in the present embodiment In line locating part 420, by inserting paragraph 423 be designed as truncated cone-shaped and from insertion end to the end diameter being connect with flange sections 424 by It is decrescence small.

In conducting wire connection procedure, first conducting wire is passed through from the annular crossed beam trunking 426 in the flange sections 424 of limiting section 422, Then it so that conducting wire is inserted into crossing in line gap 425 and being pierced by line gap 425 between interconnecting piece 421 and inserting paragraph 423, stretches Enter outside interconnecting piece 421, controls position of the limiting section 422 in interconnecting piece 421 by connecting bolt 427, and with limiting section 422 It is gradually inserted in interconnecting piece 421, the line gap 425 of crossing between limiting section 422 and interconnecting piece 421 narrows, and realizes to conducting wire It compresses, then realizes and adjust the length that conducting wire stretched out line gap 425 by connecting bolt 427.Due to interconnecting piece 421 and conducting wire It is connected through a screw thread between insertion end, so as to realize that entire wire restraint part 420 is inserted in conducting wire by rotary connector 421 Enter the position in end, interconnecting piece 421 is fully screwed when accessing conducting wire, reaches the most deep position of conducting wire insertion end, ensures Conductive contact head and the bottom surface of conducting wire insertion end contact with each other, this kind of connection type can realize the flexible tune to lead location Section avoids poor wire connection, improves conducting wire connective stability.

Meanwhile the connection of conducting wire is connected merely by the mode of compression in the present embodiment, without existing It screws, does not generate torsion, pulling force, can fully reduce the damage to terminal.

In short, the foregoing is merely presently preferred embodiments of the present invention, it is all according to impartial made by scope of the present invention patent Variation and modification, should all belong to the covering scope of patent of the present invention.
