[0023] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0024] refer to Figures 1 to 3 , this embodiment provides a wire connector, including a wire clamp, which is made of conductive material. The wire clamp includes a common arm 11 and two clamping mechanisms that are symmetrically distributed with the center of the common arm 11 as a symmetrical point. The clamping mechanism includes a fixed clamp 12 and an L-shaped limit block 13. The fixed clamp 12 and the L-shaped limit block 13 are respectively fixedly arranged at the two ends of the same side of the common arm 11, and the common arm 11, the fixed clamp 12 and the L-shaped limit block 13 are connected as an integral unit; an installation cavity 14 is formed between the L-shaped limit block 13 and the common arm 11, and a movable block 2 that can move up and down is arranged in the installation cavity 14, and a wire pressing block 3 is arranged at one end of the movable block 2 close to the fixed clamp 12. The opposite sides of the fixed clamp 12 and the wire pressing block 3 are both arc-shaped, and a wire passing port 15 is formed between the fixed clamp 12 and the wire pressing block 3, and the wire passing port 15 is used to place the wire.

[0025] A plurality of inclined grooves 21 are evenly arranged on the side of the movable block 2 away from the common arm 11 . The inclined grooves 21 include connected right-angled sides 211 and hypotenuses 212 . The right-angled sides 211 are located on the side close to the fixed clamp 12 , and the hypotenuses 212 are located on the side away from the fixed clamp 12 .

[0026] The L-shaped limit block 13 is respectively provided with a vertical threaded hole 131 and a horizontal through hole 132, the threaded hole 131 is threadedly connected with an adjusting bolt 4, the tail of the adjusting bolt 4 passes through the threaded hole 131 and is rotatably connected to the movable block 2, and the through hole 132 is slidably connected with a limit assembly.

[0027] The limiting assembly includes a limiting rod 51, a block 52 and a first spring 53. The limiting rod 51 passes through the through hole 132 and is slidably arranged in the through hole 132. The first end of the limiting rod 51 abuts against the movable block 2, and the first end of the limiting rod 51 is provided with an inclined surface 511 matching the inclined groove 21. The second end of the limiting rod 51 is fixedly connected to the block 52; the outer diameter of the block 52 is larger than the inner diameter of the through hole 132, the first spring 53 is sleeved on the limiting rod 51, and the two ends of the first spring 53 are respectively fixedly connected to the L-shaped limiting block 13 and the block 52. When the movable block 2 moves toward the direction approaching the fixed clamp 12, one side of the oblique side 212 of the inclined groove 21 will squeeze the inclined surface 511 of the limiting rod 51, so that the limiting rod 51 moves in the direction away from the movable block 2, so that the movable block 2 can continue to move; when the movable block 2 moves in the direction away from the fixed clamp 12, one side of the right-angle side 211 of the inclined groove 21 will be stuck by the limiting rod 51, thereby preventing the movable block 2 from moving, achieving a non-return effect, effectively avoiding the situation where the wire pressing block 3 loosens the wire due to the loosening of the adjusting bolt 4, and improving the stability and safety of the device.

[0028] In this specific embodiment, the wire pressing block 3 and the movable block 2 are connected by a plurality of second springs 31. Since the spring will generate elastic force within a certain compression range, the provision of the second spring 31 can avoid the problem of the wire pressing block 3 being loosened due to the movement of the wire or the thermal expansion and contraction of the wire; at the same time, it can effectively solve the problem that the inclined surface 511 of the first end of the limit rod 51 cannot be completely engaged with the inclined groove 21 when the wire pressing block 3 abuts against the wire.

[0029] In this specific embodiment, a slide groove 111 is provided on the side of the common arm 11, and a slider 22 is slidably connected in the slide groove 111, and the slider 22 is fixedly connected to the movable block 2. The provision of the slide groove 111 and the slider 22 further improves the stability of the movable block 2 when it moves up and down.

The connecting head 41 is rotatably connected to the connecting groove 23, so that when the adjusting bolt 4 is rotated, the movable block 2 will not rotate accordingly.

[0031] In this specific embodiment, the outer sheath of the wire clamp is provided with an insulating protective shell 6, and the insulating protective shell includes a left protective shell 61 and a right protective shell 62 that are connected to each other. The insulating protective shell 6 is made of insulating material to improve the protection capability of the wire connector.

[0032] The working principle of the utility model is as follows:

[0033] When in use, first strip off the insulation of part of the wire, and place the bare wire part of the wire with the insulation stripped off into the wire passing opening 15, by rotating the adjusting bolt 4, under the push of the adjusting bolt 4, the movable block 2 and the wire pressing block 3 connected thereto move toward the fixed clamp 12, and under the joint action of the wire pressing block 3 and the fixed clamp 12, the bare wire part of the wire is fixed in the wire passing opening 15; when removing, it is necessary to pull the limit rod 51 out of the inclined groove 21 in the direction away from the movable block 2, and at the same time rotate the adjusting bolt 4 to move the movable block 2 in the direction away from the fixed clamp 12, so that the wire can be removed.
