Detailed Description

The utility model is further illustrated below with reference to examples.

Examples

The wire pressing mechanism of the wiring terminal shown in fig. 1-5 comprises a plastic shell 1 and a cover 2, wherein the cover 2 is fastened with the plastic shell 1 or fixed in a fixing mode such as a screw, the plastic shell 1 is provided with a track, the wiring terminal can be conveniently installed on the guide rail, a wire pressing mechanism for pressing a wire is arranged in the wiring terminal, the wire pressing mechanism comprises a metal conductive piece 3 fixed on the plastic shell 1, a spring piece 4 for elastically pressing the wire on the conductive piece 3 and a handle 5, the handle 5 is rotatably connected on the plastic shell 1, a cylinder 11 which is arranged in a protruding mode is arranged on the plastic shell 1, a through hole 51 which is movably sleeved on the cylinder 11 is arranged on the handle 5, the spring piece 4 is rotatably matched in the plastic shell 1, the spring piece 4 is provided with a bent rotating part 41 in the embodiment, and the rotating part 41 is movably sleeved on a rotating shaft 12 of the plastic shell 1. The handle 5 is provided with a top pressing part 52 for pressing the elastic sheet 4 and a hook part 53 for hooking the elastic sheet 4, one end of the elastic sheet 4 extends to the range of the moving track of the hook part 53 of the handle 5, and when the handle 5 rotates to the hook part 53 to push the elastic sheet 4, the elastic sheet 4 rotates relative to the plastic shell 1 until the lower end of the elastic sheet 4 is separated from the conductive piece 3 or the conductive wire. In order to facilitate the pulling-up of the handle 5, the end of the handle 5 extending to the outside of the plastic case 1 is tilted upward in the present embodiment.

In order to avoid slipping when the handle 5 is lifted, the upper and lower surfaces of the tilting part are provided with anti-slip lines.

Because the elastic force of the elastic sheet 4 needs to be generated by pressing the handle 5 downwards to abut against, in order to prevent the handle 5 from being opened automatically or opened accidentally, in this embodiment, a bending portion 42 is provided at one end of the elastic sheet 4 abutting against the handle 5, and when the handle 5 is pressed downwards to a limited state, the inclined surface of the pressing portion 52 of the handle 5 abuts against the surface of the bending portion 42, so that the elastic sheet 4 can form the elastic force for pushing the handle 5 to keep the handle 5 in the pressed state. Therefore, the elastic sheet 4 has the function of pressing the lead at one end to prevent the lead from sliding out, and pressing the handle 5 at the other end to prevent the handle 5 from being opened accidentally. The other function of the hook portion 53 is that when the handle 5 is in the state of being broken off, the hook portion 53 of the handle 5 abuts against the bending portion 42 of the elastic sheet 4, and since one end of the handle 5 is heavier than the other end in the breaking off position, the elastic sheet 4 is kept away from the conductive member 3 in the state of being broken off, thereby facilitating the insertion of the conductive wire.

The plastic shell 1 is provided with a limiting table top 13 for limiting the rotation angle of the elastic sheet 4.

In order to further ensure that the handle 5 is kept in the pressed state after being pressed down and cannot be easily separated, a positioning mechanism is arranged between the side surface of the part of the handle 5 embedded in the plastic shell 1 and the plastic shell 1 in the pressed state of the handle 5. The positioning mechanism comprises a concave part 54 arranged on the side surface of the handle 5 or the inner wall of the caulking groove of the plastic shell 1, a convex part 14 clamped into the concave part 54 is arranged on the corresponding inner wall of the caulking groove of the plastic shell 1 or the side surface of the handle 5, and the convex part 14 is clamped with the concave part 54 after the handle 5 is pressed down.
