in the figure: the anti-rotation bolt comprises a pressing sleeve 1, an inner through hole 101, a lock pin 2, a stud 3, a spring 4, a sealing ring 5, an insulating shell 6, an outer through hole 601, a conductor 7, a welding wire cup 8, a threaded column 9, an anti-rotation step 10, a rectangular through hole 11, a guiding chamfer 12, a kidney-shaped hole 13, a nut 14 and a mounting plate 15.

Detailed Description

The invention is further described below with reference to the accompanying drawings.

As shown in fig. 1-3, a spring press type wiring terminal comprises an insulating shell 6, a stud 3, a press sleeve 1, a conductor 7, a lock pin 2 and a spring 4, wherein a rectangular through hole 11 is formed in the side wall of the upper part of the stud 3, an anti-rotation step 10 is arranged in the middle of the stud 3, and the lower part of the stud 3 is connected with a welding wire cup 8 through a threaded column 9; 6 open-top ends of insulating casing, outer cross connection hole 601 is seted up to 6 upper portion both sides lateral walls of insulating casing, outer cross connection hole 601 outer mouthful design is guide chamfer 12 structure, set up waist shape hole 13 on 6 bottoms of insulating casing, press cover 1 to cup joint in 6 open-top ends of insulating casing, press and set up interior cross connection hole 101 on 1 lower part both sides lateral wall of cover, double-screw bolt upper portion overcoat spring 4 cross-under is in pressing the cover, double-screw bolt middle part is through preventing changeing 10 cooperation fixed cross connection waist shape hole 13 in and its lower extreme stretches out the insulating casing bottom and connect welding cup 8 under threaded column 9, press cover 1 bottom pressure spring 4, cross connection lockpin 2 in interior cross connection hole and the rectangle through-hole, interior cross connection hole height is less than the rectangle through-hole.

In the above embodiment, the conductor 7 may be used as a connecting wire, or replaced with a wire, and after the conductor 7 passes through the outer through hole 601, the conductor passes through the inner through hole and the rectangular through hole in sequence, and then passes through the inner through hole and the outer through hole on the other side. The conductor and the lockpin are smaller than the height of the inner through hole in the height direction, the height of the inner through hole is smaller than the height of the rectangular through hole, when the conductor is locked, the conductor is tightly pressed by the spring to push the pressing sleeve to drive the lockpin to tightly abut against the upper portion of the rectangular through hole, when the conductor needs to be loosened, the pressing sleeve is pressed down, a gap is reserved above the inner through hole of the pressing sleeve to press the pressing sleeve down, the compression spring at the lower end of the pressing sleeve descends, the dead weight of the lockpin descends to loosen the abutment against the conductor, and therefore loosening and releasing of the conductor can be achieved. When the installation is used, the threaded column penetrates through the mounting plate and is screwed with the nut on the threaded column to be pressed and connected with the mounting plate to be compressed with the end face of the bottom end of the insulating shell, and the sealing ring is embedded on the end face of the bottom end of the insulating shell and used for improving the installation sealing performance.

In order to further improve the joint performance of conductor, set up the lockpin outer wall and prevent changeing the screw thread, effectively prevent that the conductor pine from taking off the aversion when supporting tight conductor. In order to further improve the stability of the stud penetrating and connecting insulation shell, the anti-rotation step can be designed into a structure that two parallel planes are milled on two sides of a round table; or polygonal, which is convenient for clamping and rotation prevention.
