An arc-shaped plate 5 is fixedly connected to the lower side of the right end of the sleeve 1. An arc-shaped groove 4 is provided on the upper side of the right end of the sleeve 1. The shape of the outer wall of the arc-shaped plate 5 is fitted with the shape of the inner wall of the arc-shaped groove 4. A limit box 3 is fixedly connected to the right side of the rear end of the sleeve 1. An L-shaped insert block 2 is fixedly connected to the right side of the front end of the sleeve 1. A movable cavity 13 is provided on the inner wall of the front end of the L-shaped insert block 2. A threaded barrel 6 is fixedly connected to the left end of the sleeve 1. A rubber ring 10 is fixedly connected to the left side of the inner wall of the threaded barrel 6. Two sleeves 1 with the same structure are required to be used in cooperation. Place the sleeves 1 opposite to each other, then pass the two wires through the rubber rings 10 on the opposite sides of the two sleeves 1 respectively, and then connect the wire ends of the two wires. After the connection is completed, rotate any one of the sleeves 1 to align its arc-shaped groove 4 with the arc-shaped plate 5 on the other sleeve 1, and align its arc-shaped plate 5 with the arc-shaped groove 4 on the other sleeve 1. Then move the two sleeves 1 relative to each other on the wire surface so that the corresponding arc-shaped plates 5 are inserted into the arc-shaped grooves 4 on the other sleeve 1. Through the fit between the arc-shaped groove 4 and the arc-shaped plate 5, the sealing performance of the outside of the joint can be improved, avoiding moisture from entering and eroding. At the same time, the two limit boxes 3 are respectively inserted and fixed with the two L-shaped insert blocks 2.

[0033] The slide plate 16 slidably connected to the left side of the upper and lower ends of the inner wall of the active cavity 13 and the rotating shaft 14 rotatably connected at the front right part of the upper and lower ends of the inner wall of the active cavity 13, the outer wall of the rotating shaft 14 is fixedly connected with a clamping block 9, the rear end of the slide plate 16 is connected to the inner wall of the active cavity 13 through a spring 17, one end of the spring 17 is fixedly connected to the rear end of the inner wall of the active cavity 13, and the other end of the spring 17 is fixedly connected to the rear end of the slide plate 16, and the middle part of the upper and lower ends of the clamping block 9 is fixedly connected with a baffle 15, and the baffle 15 will contact the inner wall of the active cavity 13 when the clamping block 9 rotates outward to form a clamping block. The limit of block 9 prevents the block 9 from rotating too much and leaving the range of the active cavity 13. The left side of the rear end of the block 9 fits with the front end of the slide plate 16. The limit box 3 passes through the L-shaped plug block 2 respectively, and presses the block 9 to rotate and retract into the active cavity 13. The slide plate 16 slides under the force and squeezes the spring 17. Then, after the engaging groove 12 passes through one end of the arc surface of the block 9, under the elastic force of the spring 17, the slide plate 16 is relocated and the block 9 is pushed outward. At this time, one end of the arc surface of the block 9 will clamp the inner wall of the engaging groove 12, thereby forming a limit between the two sleeves 1.

[0034] A slot 11 is provided on the rear side of the inner wall of the limit box 3, and a locking slot 12 is provided on the left side of the rear end of the inner wall of the slot 11. The shape of the right end of the L-shaped plug block 2 matches the shape of the inner wall of the slot 11. Notches 7 are provided on the left sides of both the front and rear ends of the threaded barrel 6. The threaded barrel 6 is a plastic product. After the outer part thereof is subjected to a certain pressure, the part of the threaded barrel 6 at the notch 7 will squeeze the rubber ring 10 in the relative direction. The outer wall of the threaded barrel 6 is threadedly connected with a screw sleeve 8. The screw sleeves 8 on both sides are rotated respectively to make the screw sleeves 8 slide and move in relative directions. When the screw sleeve 8 moves, the part of the threaded barrel 6 corresponding to the notch 7 will be squeezed, so that the gap of the notch 7 is reduced and the rubber ring 10 is squeezed, the wiring surface is tightly wrapped, and the sealing effect of the internal space of the sleeve 1 is improved. Except for the spring 17, the practical structure is made of plastic material and has insulation.

[0035] Working principle: First, two sleeves 1 with the same structure are required to be used in cooperation. Place the sleeves 1 opposite to each other, then pass the two wiring lines through the rubber rings 10 on the opposite sides of the two sleeves 1 respectively. Next, connect the wire ends of the two wiring lines. After the connection is completed, rotate any one of the sleeves 1 so that its arc-shaped groove 4 aligns with the arc-shaped plate 5 on the other sleeve 1, and its arc-shaped plate 5 aligns with the arc-shaped groove 4 on the other sleeve 1. Then, move the two sleeves 1 relative to each other on the surface of the wiring, so that the corresponding arc-shaped plates 5 on each side are inserted into the arc-shaped grooves 4 on the other sleeve 1. At the same time, the two limit boxes 3 on both sides respectively pass through the L-shaped inserts 2, and press the latch 9 to rotate and retract into the movable cavity 13. The slide plate 16 slides under force and compresses the spring 17. Then, after the engaging groove 12 passes through the arc-shaped end of the latch 9, under the elastic force of the spring 17, the slide plate 16 bounces back to its original position and pushes the latch 9 outwards. At this time, the arc-shaped end of the latch 9 will clamp the inner wall of the engaging groove 12, thus forming a limit between the two sleeves 1. Through the fit between the arc-shaped groove 4 and the arc-shaped plate 5, the sealing performance of the outside of the connector can be improved, preventing water vapor from entering and corroding. Then, rotate the screw sleeves 8 on both sides respectively, so that the screw sleeves 8 slide in the opposite direction. While the screw sleeves 8 are moving, they will squeeze the corresponding part of the threaded cylinder 6 at the notch 7, causing the gap of the notch 7 to narrow and squeezing the rubber ring 10, tightly wrapping the surface of the wiring, and improving the sealing effect of the internal space of the sleeve 1.

[0036] It has been verified that the joint protection structure for electrical installation and commissioning of the present utility model has a reasonable structural design. The two structures are connected to each other, which can provide good sealing for the connected wiring joint, making it not corroded by water vapor and preventing operators from accidentally touching it, thus eliminating potential safety hazards. In addition, through the insertion connection of the limit box at the open end of the sleeve and the L-shaped insert, during the process of the wire end being retracted into the sleeve, there is no need for bending, avoiding the breakage of the joint and affecting the working progress of the wiring connection. It has good application prospects.
