[0038] Embodiment 1
[0039] As shown in Figs. 1-6 A coal mine mechanical and electrical equipment wiring device, comprising a copper bar wiring mechanism. The copper bar wiring mechanism realizes direct plug-in mode wiring, and maintains the locking state after wiring, avoiding the disconnection between the input copper bar and the output copper bar during the working process.
[0040] Specifically, the copper bar wiring mechanism comprises a wiring box body 1 (insulated plastic material, rectangular shape), and a copper bar wiring structure is assembled in the wiring box body 1 and connected with the copper bar wiring structure, so that the input copper bar and the output copper bar are electrically connected through the copper bar wiring structure.
[0041] Specifically, the copper bar wiring structure comprises a pair of spaced metal wiring strip plates 61 (symmetrically arranged left and right), and the input copper bar and the output copper bar are electrically connected through the metal wiring strip plates 61.
[0042] The metal wiring strip plate 61 (made of copper) comprises a straight part 611, and a bending part 612 is integrally formed at each end of the straight part 611 (the bending part 612 is inwardly bent, that is, the bending parts 612 on the two metal wiring strip plates 61 face each other), and the copper bar is clamped between the bending parts 612.
[0043] At the same time, in order to increase the electrical contact, a plurality of protruding structures 63 are integrally formed on the side walls of the bending parts 612 which face each other. When the copper bar is inserted between the bending parts 612, first, based on the elasticity of the metal wiring strip plate 61 itself, the bending parts 612 elastically deform and elastically extrude on the copper bar, and then, under the action of the protruding structures 63, the electrical contact effect is increased.
[0044] The straight part 611 is fixedly connected with a pair of front and rear spaced spring structures 62, and the spring structures 62 are fixedly connected to the inner side wall of the wiring box body 1.
[0045] Specifically, the spring structure 62 comprises an insulating seat 622 fixedly connected to the straight part 611, a spring short sliding rod 623 is fixedly connected to the insulating seat 622, and a sliding pipe 621 slidingly connected to the spring short sliding rod 623 is fixedly connected to the inner side wall of the wiring box body 1; a spring is sleeved on the spring short sliding rod 623, and the spring is fixedly connected to the insulating seat 622 and the sliding pipe 621. Correspondingly, a ring-shaped spring seat is fixedly connected to the mouth of the sliding pipe 621, and the spring 624 is fixedly connected to the ring-shaped spring seat.
[0046] When the copper bar is inserted, at this time, under the thickness of the copper bar, the two metal wiring strip plates 61 are away from each other, and in this process, the spring short sliding rod 623 slides into the sliding pipe 621, and the spring 624 is compressed. Under the elastic restoring force of the spring 624, the metal wiring strip plate 61 has a restoring tendency, and in this way, the clamped input copper bar and output copper bar have high clamping stability, so as to provide electrical contact efficiency.
[0047] Embodiment 2
[0048] As Figs. 1-6As shown, in this embodiment, based on the structure of embodiment 1, both ends of the junction box 1 are fixedly connected to copper busbar wire clamping structures 4. The copper busbar wire clamping structure 4 includes a wire clamping box 2, and a pair of wire clamping wheels 41 (made of insulating rubber) are rotatably connected inside the wire clamping box 2. The wire clamping wheels 41 are respectively provided with wire clamping groove structures on their outlines. The wire clamping wheels 41 are locked by a locking structure. The copper busbar wire (i.e., the wire on the copper busbar) is squeezed and guided through the wire clamping groove structures and enters the junction box 1. The wire clamping wheels 41 are positioned by the locking structure.
[0049] Specifically, a through channel 411 is formed between the wire-holding grooves of the wire-holding wheel 41; correspondingly, an inlet hole communicating with the through channel 411 is provided on the junction box body 1.
[0050] During operation, after the copper busbar is pushed into the slotted structure, the wire on the copper busbar is then pushed into the slotted structure and forms friction with the clamping wheel 41. At this time, the operator can rotate the clamping wheel 41. Under the frictional pushing force of the clamping wheel 41, the wire and copper busbar are pushed in with assistance. Then the copper busbar enters the junction box 1 and is clamped between the metal connection strip plates 61 in the above manner.
[0051] Subsequently, in order to prevent the conductor from pulling the copper busbar away from the metal connection strip plate 61 during the process of the conductor being stretched, the locking structure positions the wire clamping wheel 41 so that it does not move. At this time, because the wire clamping wheel 41 is pressed on the conductor, the conductor does not move when the wire clamping wheel 41 is not in place, thus maintaining the stability of the electrical connection.
[0052] Example 3
[0053] like Figs. 1-6 As shown, in this embodiment, based on the structure of embodiment 2, a lower rotating shaft is fixedly connected to the bottom of the wire clamping wheel 41, and the lower rotating shaft is rotatably connected to the bottom of the wire clamping box 2. An upper rotating screw is fixedly connected to the top of the wire clamping wheel 41, and the upper rotating screw is rotatably connected to the top of the wire clamping box 2. The upper rotating screw passes through the top of the wire clamping box 2. A positioning compression nut 42 is threadedly connected to the upper rotating screw, and the positioning compression nut 42 is pressed and positioned on the top of the wire clamping box 2.
[0054] After the copper busbar is installed, tighten the clamping nut 42. Because the clamping nut 42 presses against the top of the clamping box 2 and forms a large clamping force, when the wire is pulled, the clamping wheel 41 is not easy to rotate in the opposite direction, thus keeping the wire clamped.
[0055] The aforementioned cable box 2 has an integrally formed cable inlet box 3, and the cable inlet box 3 has a lead wire hole.
[0056] Of course, the above description is not a limitation of the utility model, the utility model is also not limited to the above examples, the changes, modifications, additions or replacements made by the person skilled in the art within the essential scope of the utility model should also belong to the protection scope of the utility model.
