The two groups of terminal posts correspond one to one, and an auxiliary terminal mechanism is provided on the front face of the box corresponding to each group of terminal posts in a horizontally movable manner.

[0010] In one embodiment, each group of terminal assembly includes a plurality of terminals arranged horizontally and evenly spaced, each auxiliary terminal mechanism includes a horizontally arranged moving bar, a plurality of positioning sleeve mechanisms arranged evenly spaced above the moving bar, and a telescopic positioning assembly arranged at the bottom of the moving bar, one end of the telescopic positioning assembly is fixed to the bottom of the moving bar, and the other end is embedded in the box, and the distance between the moving bar and the box is adjusted by the telescopic positioning assembly;

[0011] The number of the positioning sleeve mechanisms is the same as that of the terminal posts and they correspond one to one. Each positioning sleeve mechanism is movably sleeved with the corresponding terminal post to achieve positioning and sealing when the terminal post is matched with the part to be connected.

[0012] In one embodiment, the telescopic positioning assembly includes at least two manual telescopic rods arranged in parallel on the lower surface of the moving bar, the outer sleeve end of each manual telescopic rod is embedded in the outer wall of the box, and the inner sleeve end of each manual telescopic rod is welded to the surface of the moving bar.

[0013] Specifically, the back (lower surface) of the moving bar is symmetrically embedded in the manual telescopic rod and the other end of the manual telescopic rod is embedded in the outer wall of the box body, and the manual telescopic rod is used to position the moving bar without hindering the displacement of the moving bar. The manual telescopic rod is a secondary telescopic sleeve.

[0014] In one embodiment, the positioning sleeve mechanism includes a positioning sleeve fixed on the moving bar, a sliding sleeve arranged on a rectangular rod at one end of the positioning sleeve away from the moving bar, and a sleeve arranged at the end of the rectangular rod extending out of the positioning sleeve, and each sleeve is interactively sleeved with a corresponding terminal.

The positioning sleeve is used to limit the rectangular rod and does not hinder the movement of the rectangular rod.

[0016] In one embodiment, the axial direction of the sleeve, the axial direction of the positioning sleeve, the axial direction of the terminal and the length direction of the rectangular rod are parallel to each other.

[0017] In one embodiment, the positioning sleeve is connected to the moving strip in an orthogonal manner, and a fitting groove is provided at the end of the sleeve close to the terminal.

[0018] In one embodiment, the positioning sleeve is provided with a positioning assembly for positioning the rectangular rod, the positioning assembly includes a spring telescopic rod fittedly connected to the outside of the rectangular rod, and an L-shaped plate for installing the spring telescopic rod, the L-shaped plate is installed on the outer wall of the positioning sleeve, one end of the spring telescopic rod is fixed on the L-shaped plate, and the other end passes through the outer wall of the positioning sleeve to fit with the rectangular rod.

[0019] Specifically, the telescopic force of the spring telescopic rod can squeeze the rectangular rod, so that the rectangular rod is squeezed and fixed. The L-shaped plate is used to fix the spring telescopic rod, changing the difficulty of fixing the spring telescopic rod.

[0020] In addition, the sleeve is driven to move by the rectangular rod, and the rectangular rod is positioned under the action of the spring telescopic rod. The moved sleeve is sleeved on the outside of the terminal and enters into the Y-shaped copper nose (part to be connected), so that the Y-shaped copper nose (part to be connected) is positioned left and right, and there is no need for people to support it with their hands. Then the terminal can be directly rotated to lock the Y-shaped copper nose (part to be connected), thereby achieving the purpose of increasing the stability, sealing and fit of the connection between the Y-shaped copper nose (part to be connected) and the terminal.

At this time, the Y-shaped copper nose of the connecting wire is inserted into the extrusion part of the terminal, and then the personnel moves the sleeve. When the sleeve moves, it drives the rectangular rod to move inside the positioning sleeve, and uses the spring telescopic rod to squeeze and fix the rectangular rod. The moved sleeve enters the outside of the Y-shaped copper nose, so as to achieve the purpose of positioning the Y-shaped copper nose, and can seal the connection between the Y-shaped copper nose and the connecting column, thereby increasing the tightness, fit and sealing of the connection between the Y-shaped copper nose and the connecting column, and then the personnel turns the rotating button on the outside of the terminal to squeeze and fix the Y-shaped copper nose, and at the same time pulls the moving bar synchronously. When the moving bar moves, it can drive the manual telescopic rod to stretch, and the moving bar drives multiple sleeves and Y-shaped copper noses to separate through the positioning sleeve and the rectangular rod.
