[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] According to the attached Figure 1-6 As shown, an embodiment of the present invention provides a reactive compensator that is easy to remove and connect wires, including a compensator body 1, a terminal block 2 is provided on the right side of the compensator body 1, a symmetrically distributed connecting block 21 is provided inside the terminal block 2, and a terminal mechanism for fixing the wire is provided on the inner side of the connecting block 21, and the terminal mechanism includes a terminal sleeve 3 and a spiral sleeve 4, and the spiral sleeve 4 is located between the terminal sleeve 3 and the connecting block 21, and is used to squeeze the terminal sleeve 3 to fix the wire. A protective shell 5 is clamped and fixed on the right side of the terminal block 2, and a protective mechanism for protecting the wire is provided on the inner side of the protective shell 5, and the protective mechanism includes a movable frame 6, an arc frame 61 and a spring 63.

[0028] When wiring, first, pass the wire through the protective shell 5, then put the spiral sleeve 4 on the wire, and insert the end of the wire into the wiring sleeve 3. After that, rotate the spiral sleeve 4 so that the spiral sleeve 4 gradually approaches the wiring sleeve 3 and squeezes the shrinkage piece 31 on the wiring sleeve 3 so that the shrinkage piece 31 gradually shrinks and contacts the wire over a large area, locking and fixing the wire, thereby effectively preventing the wire from falling off. When the wire is connected, the protective shell 5 is clamped and fixed to the wiring seat 2. At this time, under the elastic action of the spring 63, the movable frames 6 on the upper and lower sides are gradually approached, and the arc frame 61 is clamped on the upper and lower sides of the wire, thereby further fixing the wire and improving the fixing effect of the wire. At the same time, the arc frame 61 and the protective shell 5 cooperate with each other to protect the stripped wire end, and have good dustproof, waterproof and corrosion-resistant effects.

[0029] A display screen 11 is installed on the front side of the compensator body 1. Several evenly distributed control buttons 12 are provided on the front side of the compensator body 1 and below the display screen 11. The display screen 11 and the control buttons 12 facilitate control of the compensator body 1.

[0030] The wiring sleeve 3 is arranged on the inner side of the connecting seat 21 and close to the center. A shrinkage sheet 31 distributed in a ring array is arranged on the right side of the wiring sleeve 3. The outer surface of the shrinkage sheet 31 is an arc-shaped inclined surface. The wiring sleeve 3 and the shrinkage sheet 31 are both made of metal copper and have good conductive efficiency. When the shrinkage sheet 31 shrinks and contacts the surface of the wire, there is a large contact area between the wiring sleeve 3 and the wire, which can achieve a good conductive effect.

[0031] An internal thread 211 is provided on the circumferential inner wall of the connecting seat 21, and the circumferential outer wall of the spiral sleeve 4 is threadedly connected to the internal thread 211. An integrally formed adjusting head 41 is provided on the right side of the spiral sleeve 4. When the adjusting head 41 is rotated, the spiral sleeve 4 can be driven to move. An extrusion surface 42 is provided on the inner wall of the spiral sleeve 4 and on the side close to the shrinkage piece 31. The extrusion surface 42 is an annular inclined surface and cooperates with the outer surface of the shrinkage piece 31.

[0032] When the end of the wire is inserted into the inner side of the wiring sleeve 3, the adjusting head 41 is rotated to drive the spiral sleeve 4 to rotate, so that the spiral sleeve 4 and the internal thread 211 move relative to each other, and the spiral sleeve 4 can drive the extrusion surface 42 to gradually approach the shrinkage piece 31. Since the surfaces of the extrusion surface 42 and the shrinkage piece 31 are both inclined, the spiral sleeve 4 can gradually squeeze the outer surface of the shrinkage piece 31 through the extrusion surface 42, so that the shrinkage piece 31 gradually shrinks inward and fits with the wire over a large area, thereby locking and fixing the wire, while ensuring the conductive effect, it can effectively prevent the wire from falling off.

[0033] Symmetrically distributed elliptical holes 51 are provided on the right side of the protective shell 5 to facilitate the movement of the arc frame 61. Symmetrically distributed card blocks 22 are provided on the outer wall of the terminal block 2, and a card slot 52 is provided on the inner wall of the protective shell 5 near the terminal block 2. The protective shell 5 is fixed to the card block 22 through the card slot 52. The protective shell 5 can protect the terminal block 2 and the wire end after wiring to prevent the stripped wire end from contacting the outside world, thereby achieving good dustproof, waterproof and anti-corrosion effects.

[0034] The upper and lower sets of movable frames 6 are symmetrically arranged on the inner side of the protective shell 5 and are slidably connected to the protective shell 5. On the movable frame 6 and on the inner side of the elliptical hole 51, there are arc frames 61 symmetrically distributed on the left and right. Rubber pads 62 are bonded and fixed on the inner wall of the arc frames 61. The rubber pads 62 play an insulating and protective role on the outer side of the wire end.

[0035] The spring 63 is arranged on the inner side of the protective shell 5 and near the four corners. One end of the spring 63 is fixedly connected to the inner wall of the protective shell 5, and the other end of the spring 63 is connected to the end of the movable frame 6. Push plates 64 are provided on the opposite sides of the two sets of movable frames 6 and near the center. A slide groove 65 is provided on the movable frame 6 and on one side of the push plate 64. The push plates 64 on the upper and lower movable frames 6 respectively pass through the slide grooves 65 on the opposite sides and extend to the outside of the movable frame 6.

[0036] When the push plate 64 is pressed, the push plates 64 on the upper and lower sides can be gradually separated, and the rubber pad 62 can be separated from the surface of the wire. At the same time, the spring 63 can be gradually compressed, so as to facilitate the adjustment of the position of the protective shell 5 during the wiring process. When the push plate 64 is released, the elastic action of the spring 63 pushes the push plates 64 on the upper and lower sides to gradually approach each other, and the arc frame 61 drives the rubber pad 62 to contact the surface of the wire, thereby improving the fixing effect of the wire and cooperating with the protective shell 5 to enhance the protection effect of the stripped part of the wire.

[0037] When using the reactive compensator that is easy to disconnect wires according to the present invention, first, press the push plate 64 to gradually separate the movable frame 6 and the arc frame 61 on the upper and lower sides, then pass the wire to be connected through the elliptical hole 51, then release the push plate 64, and under the elastic action of the spring 63, the wire surface of the arc frame 61 is in contact, and the protective shell 5 is fixed to the outside of the wire, then the spiral sleeve 4 is sleeved on the outside of the wire, so that the end of the wire is inserted into the wiring sleeve 3, and then the spiral sleeve 4 is driven to rotate by the adjusting head 41, so that the spiral sleeve 4 and the internal thread 211 move relative to each other, and the shrinkage piece 31 is gradually squeezed by the extrusion surface 42, so that the shrinkage piece 31 shrinks inward and contacts with a large area of ​​the wire end, thereby locking and fixing the wire;

[0038] Furthermore, after the wire is fixed, the push plate 64 is pressed to separate the arc frame 61 from the surface of the wire. Then, the protective shell 5 is moved and the protective shell 5 is fixed to the card block 22 through the card slot 52. Then, the push plate 64 is released. Under the elastic action of the spring 63, the arc frame 61 drives the rubber pad 62 to contact the surface of the wire, thereby further fixing the wire and cooperating with the protective shell 5 to provide protection at the wiring point.
