[0001] The utility model relates to the technical field of electrical engineering, in particular to a rapid connection device for electrical engineering lines. Background Technique

[0002] The traditional and broad definition of electrical engineering refers to the sum of related disciplines used to create electrical and electronic systems. With the rapid development of science and technology, the concept of electrical engineering has far exceeded the scope of the above definition. Professors at Stanford University pointed out that today's electrical engineering covers almost all engineering behaviors related to electronics and photons, and a large number of cables are especially needed for connection. Therefore, a rapid connection device for electrical engineering lines is required.

[0003] A Chinese patent discloses a rapid connection device for electrical engineering lines (authorization announcement number CN210984997U). This patented technology has tight connection, good electrical conductivity, and high safety.

[0004] In view of the above and existing related technologies, the inventor believes that the following defects often exist: the connection of existing electrical engineering lines mostly directly fixes the conductive heads, and there is a risk of electric shock during the fixing process, the safety of the fixing operation is relatively low, and the convenience of the line connection operation is relatively low, resulting in a reduction in installation efficiency. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is that in the prior art, the connection of electrical engineering lines mostly directly fixes the conductive heads, with relatively low safety and the inability to quickly connect wires. For this reason, we propose a rapid connection device for electrical engineering lines.

[0006] In order to achieve the above purpose, the present application adopts the following technical solution: A rapid connection device for electrical engineering lines, including a box body, the top of the box body is rotatably connected with a box cover through a hinge, an observation window is arranged at the front end of the box body, connection pipes are fixedly penetrated through both sides of the box body, a thread groove is arranged on the surface of one end of the connection pipe, a disc is threadedly connected to the surface of the connection pipe, four fixing rods are slidably penetrated through the surface of the connection pipe, the fixing rods are distributed in a circumferential manner, one end of the fixing rod is fixed with an insertion rod, the surface of the insertion rod is slidably connected to the inside of the disc, and the other end of the fixing rod is fixed with an arc-shaped plate.

[0007] Preferably, four guiding grooves are arranged on the surface of the disc, the guiding grooves are distributed in a circumferential manner, and the inside of the guiding grooves is slidably connected to the surface of the insertion rod.

[0008] Preferably, a limiting circular plate is fixed to the other end of the insertion rod.

[0009] Preferably, a clamping pad is fixed to the inner side of the arc-shaped plate, and the clamping pad is made of rubber.

[0010] Preferably, a mounting plate is fixed inside the box body. A first driving device is installed at one end of the mounting plate. A driving rod is arranged inside the mounting plate. A driving block is rotatably connected to the surface of the driving rod. An annular frame is fixed to the top of the driving block. A slider is slidably connected inside the annular frame. A placing rack is arranged at one end of the slider. A second driving device is installed on one side of the annular frame.

[0011] Preferably, a first sliding groove is formed in the top of the mounting plate, and the driving block is slidably connected to the inside of the first sliding groove.

[0012] Preferably, a second sliding groove is formed in the inner side of the annular frame, and the slider is slidably connected to the inside of the second sliding groove.

[0013] The technical effects and advantages of the present utility model:

[0014] In the present utility model, by placing the wire or cable to be connected inside the connecting pipe and extending it into the box body, the core wires of two or more wires are tightly connected together by twisting. Then, by rotating the disc, using the threaded connection between the threaded groove and the inside of the disc, the disc drives the insertion rod to push the fixing rod and the arc-shaped plate towards the wire or cable until they are completely fitted. Among them, the disc will not change its position without external force, thereby realizing the fixation of the wire position, ensuring that the wire will not move or be misaligned during the connection process, without the need for a complex welding or screw fixing process, and only simple operations can complete the connection, greatly improving the work efficiency, and being easy to disassemble and replace, reducing the maintenance cost and time.

[0015] In the present utility model, by placing the tape on the placing rack, starting the first driving device, the driving rod starts to rotate to drive the driving block and the annular frame to move back and forth on the surface of the driving rod, and starting the second driving device to cooperate with the first driving device, the slider drives the tape placed on the surface of the placing rack to wind the wire. By tightly winding and insulating the connection part, the stability and safety of the connection are ensured. Description of the Drawings

Connecting pipes 4 are fixedly penetrated through both sides of the box body 1. A threaded groove 6 is formed on the surface of one end of the connecting pipe 4. A disc 5 is threadedly connected to the surface of the connecting pipe 4. Four fixed rods 7 are slidably penetrated through the surface of the connecting pipe 4. The fixed rods 7 are circumferentially distributed. One end of the fixed rod 7 is fixed with an insert rod 8. The surface of the insert rod 8 is slidably connected to the inside of the disc 5. The other end of the fixed rod 7 is fixed with an arc plate 9. By placing the wire or cable to be connected inside the connecting pipe 4 and extending it into the box body 1, the core wires of two or more wires are tightly connected together by twisting. Then, by rotating the disc 5, using the threaded connection between the threaded groove 6 and the inner side of the disc 5, the disc 5 drives the insert rod 8 to push the fixed rod 7 and the arc plate 9 towards the wire or cable until they are completely fitted. Among them, the disc 5 will not change its position without external force, thereby realizing the fixation of the wire position, ensuring that the wire will not move or be misaligned during the connection process, without a complex welding or screw fixation process, and only simple operations are required to complete the connection, greatly improving the work efficiency, and being easy to disassemble and replace, reducing the maintenance cost and time.

[0023] Refer to Figure 3 As shown in the embodiment: Four guide grooves 10 are formed on the surface of the disc 5. The guide grooves 10 are circumferentially distributed. The inside of the guide grooves 10 is slidably connected to the surface of the insert rod 8. By providing the guide grooves 10, the movement of the insert rod 8 can be restricted and guided in position, improving the stability.

[0024] Refer to Figure 3As shown, in this embodiment: a limiting circular plate 11 is fixed to the other end of the insertion rod 8. By providing the limiting circular plate 11, the separation between the disc 5 and the insertion rod 8 can be avoided.

[0025] Referring to Figure 3 As shown, in this embodiment: a clamping pad 12 is fixed to the inner side of the arc-shaped plate 9. The clamping pad 12 is made of rubber. By providing the clamping pad 12, the frictional force between the arc-shaped plate 9 and the electric wire can be increased by using the rubber material of the clamping pad 12, improving the fixing effect on the electric wire.

[0026] Referring to Figure 4 As shown, in this embodiment: a mounting plate 13 is fixed inside the box body 1. A first driving device 14 is installed at one end of the mounting plate 13. A driving rod 15 is arranged inside the mounting plate 13. A driving block 16 is rotatably connected to the surface of the driving rod 15. A circular ring frame 17 is fixed to the top of the driving block 16. A slider 18 is slidably connected inside the circular ring frame 17. A placing rack 19 is arranged at one end of the slider 18. A second driving device 20 is installed on one side of the circular ring frame 17. By placing the adhesive tape on the placing rack 19 and starting the first driving device 14, the driving rod 15 starts to rotate to drive the driving block 16 and the circular ring frame 17 to move back and forth on the surface of the driving rod 15, and the second driving device 20 is started to cooperate with the first driving device 14, so that the slider 18 drives the adhesive tape placed on the surface of the placing rack 19 to wind the electric wire. By tightly winding and insulating the connection part, the stability and safety of the connection are ensured.

[0027] Referring to Figure 4 As shown, in this embodiment: a first sliding groove 21 is formed at the top of the mounting plate 13. The driving block 16 is slidably connected to the inside of the first sliding groove 21. By providing the first sliding groove 21, the driving block 16 can be assisted in moving.

[0028] Referring to Figure 4 As shown, in this embodiment: a second sliding groove 22 is formed inside the circular ring frame 17. The slider 18 is slidably connected to the inside of the second sliding groove 22. By providing the second sliding groove 22, the moving track of the slider 18 can be restricted, avoiding the slider 18 disengaging from the inside of the circular ring frame 17 and affecting the winding effect.

[0029] Working principle: the user places the wires or cables to be connected inside the connecting tube 4 and extends it to the inside of the box 1, and tightly connects the core wires of two or more wires together by twisting them. Then, by rotating the disc 5, the threaded connection between the threaded groove 6 and the inner side of the disc 5 is utilized to make the disc 5 drive the insertion rod 8 to push the fixing rod 7 and the arc plate 9 toward the wires or cables until they are fully fitted, wherein the disc 5 will not change position when not affected by external forces, thereby fixing the position of the wires and ensuring that the wires will not move or be misplaced during the connection process. No complicated welding or screw fixing process is required, and the connection can be completed with simple operations, which greatly improves work efficiency, is easy to disassemble and replace, and reduces maintenance costs and time. By setting the guide groove 10, the movement of the insertion rod 8 can be limited and guided to improve stability. By setting the limiting circular plate 11, the circular plate 11 can be avoided. Separation occurs between the disk 5 and the insertion rod 8. By setting a clamping pad 12, the rubber material of the clamping pad 12 can increase the friction between the arc plate 9 and the wire, thereby improving the fixing effect of the wire. By placing the tape on the placement rack 19, starting the first driving device 14, the driving rod 15 starts to rotate, driving the driving block 16 and the annular frame 17 to move back and forth on the surface of the driving rod 15, and starting the second driving device 20 to cooperate with the first driving device 14, so that the slider 18 drives the tape placed on the surface of the placement rack 19 to wind the wire. By tightly winding and insulating the connection, the stability and safety of the connection are ensured. By setting the first slide groove 21, the driving block 16 can be assisted in movement. By setting the second slide groove 22, the moving trajectory of the slider 18 can be restricted to prevent the slider 18 from detaching from the inside of the annular frame 17 and affecting the winding effect.
