[0028] A copper tube terminal connection device, such as Figures 1 to 4As shown, it includes a tube body 1, and conical openings 7 are provided at both ends of the tube body 1. Connecting cavities 6 are relatively opened at both sides of the inner wall of the tube body 1. The inner wall of the connecting cavity 6 is slidably connected with a connecting block 13. The connecting block 13 is provided with an inclined surface inclined to the axis of the tube body 1 at one end close to the conical opening 7. A groove 8 is provided on the outer wall of the tube body 1, and the groove 8 corresponds to the position of the connecting cavity 6. A push block 9 is slidably connected to the inner wall of the groove 8. A pressing block 10 is fixed to the bottom end of the push block 9. The pressing block 10 is in contact with the outer wall of the top end of the connecting block 13. An avoidance cavity 11 is provided at one end of the connecting cavity 6. A pressing spring 12 is fixed to the inner wall of the avoidance cavity 11. The other end of the pressing spring 12 is connected to the pressing block 10. The bottom end of the connecting block 13 is connected to An arc-shaped plate 14 is connected, and a plurality of insertion cones 19 are fixed on the inner wall of the arc-shaped plate 14. A cavity 15 is provided on the inner wall of the tube body 1, and a conductive plate 16 is fixed inside the cavity 15. Both ends of the conductive plate 16 are slidably connected with connecting plates 17, and the other end of the connecting plate 17 is connected to the arc-shaped plate 14. A reset spring 18 is fixed on the outer wall of the connecting plate 17, and the other end of the reset spring 18 is connected to the inner wall of the tube body 1. Sliding grooves 20 are provided on both sides of the outer wall of the tube body 1, and the sliding grooves 20 are staggered with the connecting cavity 6. Indicator needles 21 are slidably connected to the inner walls of both ends of the sliding grooves 20, and one end of the two indicator needles 21 is connected to the same positioning plate 23, and elastic limit blocks 22 are fixed to the inner walls of both ends of the sliding grooves 20.

[0029] When in use, the push block 9 is pushed to one side along the groove 8, driving the clamping block 10 to move, and the clamping spring 12 is compressed. When the clamping block 10 enters the avoidance cavity 11, the connecting block 13 is no longer squeezed by the clamping block 10, and is pulled upward by the reset spring 18, so that the arc plates 14 are separated from each other. Then, the wire is inserted into the tube body 1. Since the two ends of the tube body 1 are tapered openings 7, the wire can be inserted more smoothly. The inserted end of the wire pushes the positioning plate 23, driving the indicator needle 21 to move along the sliding groove 20. By observing the position of the indicator needle 21, the position of the wire insertion end can be determined. The elastic limit block 22 limits the indicator needle 21 so that when the wire is not inserted, the indicator needle 21 is located at one end of the sliding groove 20. When the wire is inserted a predetermined distance, the push block 9 is released, and the compression spring 12 pushes the push block 9 to reset, so that the compression block 10 squeezes the connecting block 13, so that the arc plates 14 are close to each other, and the insertion cone 19 breaks the outer skin of the wire and contacts the internal conductor core, and the two wires are connected through the connecting plate 17 and the conductive plate 16.

By observing the position of the indicator needle 21, the position of the wire insertion end can be determined, thereby improving the convenience of using the device.

[0031] By providing a conductive plate 16, a connecting plate 17 and an insertion cone 19, while the arc plate 14 fixes the wire, the insertion cone 19 breaks the outer skin of the wire and contacts the internal conductor core, and the two wires are connected through the connecting plate 17 and the conductive plate 16. There is no need to strip the wire in advance, and the connection is faster.

A positioning hole 4 is provided inside the connecting groove 2, and an elastic protrusion 5 is fixed on the outer wall of the slider 3. The elastic protrusion 5 is limitedly matched with the positioning hole 4.

[0034] When multiple wires are connected, the slider 3 of one device is inserted into the connecting slot 2 of another device, and the elastic protrusion 5 is squeezed and contracted. When the slider 3 is fully inserted, the elastic protrusion 5 stretches and inserts into the positioning hole 4, so that the two devices are connected to each other and multiple wires are arranged.

[0035] By providing the connection groove 2, the slider 3, the positioning hole 4 and the elastic protrusion 5, when the connection of multiple wires is completed, the slider 3 of one device is inserted into the connection groove 2 of another device, and the elastic protrusion 5 is squeezed and contracted. When the slider 3 is fully inserted, the elastic protrusion 5 stretches and inserts into the positioning hole 4, so that the two devices are connected to each other, and multiple wires are arranged to facilitate secondary maintenance.

[0036] Working principle: When in use, push the push block 9 to one side along the groove 8, drive the clamping block 10 to move, and the clamping spring 12 is compressed. When the clamping block 10 enters the avoidance cavity 11, the connecting block 13 is no longer squeezed by the clamping block 10, and is pulled up by the reset spring 18, so that the arc plates 14 are separated from each other. Then, insert the wire into the tube body 1. Since the two ends of the tube body 1 are tapered openings 7, the wire can be inserted more smoothly. The insertion end of the wire pushes the positioning plate 23, driving the indicator needle 21 to move along the sliding groove 20. By observing the position of the indicator needle 21, the position of the wire insertion end can be determined. The elastic limit block 22 moves the indicator needle 21. The guide pin 21 is located at one end of the sliding slot 20 when the wire is not inserted. When the wire is inserted into the predetermined distance, the push block 9 is released, and the compression spring 12 pushes the push block 9 to reset, so that the compression block 10 squeezes the connecting block 13, and the arc plates 14 are close to each other. The insertion cone 19 breaks the outer skin of the wire and contacts the internal conductor core, and the two wires are connected through the connecting plate 17 and the conductive plate 16. When multiple wires are connected, the slider 3 of one device is inserted into the connecting slot 2 of another device, and the elastic protrusion 5 is squeezed and contracted. When the slider 3 is fully inserted, the elastic protrusion 5 stretches and inserts into the positioning hole 4, so that the two devices are connected to each other and multiple wires are arranged.
