[0001] The utility model relates to the technical field of cable connection, in particular to a wiring component and a power distribution device. Background Art
[0002] When a power supply system fails, power workers are required to troubleshoot and repair power equipment. As an important electrical equipment, the distribution box requires power workers to perform on-site operations for both repair and maintenance.
[0003] At the power distribution site, sometimes due to the need for maintenance, it is necessary to temporarily connect a wire to draw power from the wiring point of the power distribution equipment (usually a large hexagonal head screw). The common method is to use an alligator clip to clamp onto the wiring screw head of the power distribution equipment. However, for relatively large hexagonal head screws, it is difficult for the two jaws of the alligator clip to tightly clamp the hexagonal head screw, and it is easy to fall off when there is vibration from the outside, thus causing potential safety hazards. Summary of the Utility Model

[0014] As an alternative to the wiring assembly, a tapered inclined surface is provided on the outer wall surface of each clamping head portion, and the inner wall surface of the tapered opening abuts against the tapered inclined surface.

[0021] For the wiring assembly provided by the present utility model, the insulating lining member is fixedly sleeved on the connecting portion of the conductive body. By adding the insulating lining member on the conductive body, the length of the conductive body can be shortened.

[0044] For the convenience of temporarily connecting wires to obtain power and contributing to safe electricity use, this embodiment provides a wiring assembly and a power distribution device. The following will be combined with Figures 1 to 10 to describe the specific content of this embodiment in detail. It should be noted that the first direction mentioned in this embodiment is Figure 1 the X direction in
[0045] As Figures 1 to 6 shown, the wiring assembly in this embodiment includes a conductive body 1, an insulating inner lining 2, and a fixed sleeve 5 with a first wire outlet hole 51. One end of the conductive body 1 is circumferentially and spacedly provided with a plurality of clamping heads 11, and a plurality of clamping heads 11 enclose to form a clamping space 12. In this embodiment, six clamping heads 11 are provided on the conductive body 1, and the six clamping heads 11 respectively abut against the six faces of the hexagon head screw. The other end of the conductive body 1 is provided with a connecting portion 13. One end of the insulating inner lining 2 is fixedly sleeved on the connecting portion 13. The fixed sleeve 5 is fixedly sleeved on the insulating inner lining 2, and one end of the wire 6 can pass through the first wire outlet hole 51 and the insulating inner lining 2 and be connected to the connecting portion 13.
[0046] For the wiring assembly provided in this embodiment, the insulating inner lining 2 is fixedly sleeved on the connecting portion 13 of the conductive body 1. By adding the insulating inner lining 2 on the conductive body 1, the length of the conductive body 2 can be shortened. Since the material of the conductive body 1 is copper and the material of the insulating inner lining 2 is plastic, shortening the length of the conductive body 1 helps to reduce the cost of the wiring assembly. By adding the fixed sleeve 5 on the insulating inner lining 2, the friction force of holding the wiring assembly by hand can be increased. A plurality of clamping heads 11 are circumferentially arranged at one end of the conductive body 1 away from the connecting portion 13. The maintenance personnel hold the fixed sleeve 5 and insert it towards the hexagon head screw. The larger hexagon head screw can be tightened with the clamping space 12 formed by the plurality of clamping heads 11, increasing the contact area between the clamping heads 11 and the hexagon head screw, facilitating temporary wiring for power taking, and contributing to safe electricity use.
[0047] Further, as Figure 2 combined with Figure 7 and Figure 8 shown, the wiring assembly further includes a limiting sleeve 4. The limiting sleeve 4 is movably sleeved on the conductive body 1. When the limiting sleeve 4 moves along the first direction, a plurality of clamping heads 11 can be made to contract inward, thereby reducing the clamping space 12. After the six clamping heads 11 of the conductive body 1 respectively abut against the six faces of the hexagon head screw, by moving the limiting sleeve 4 along the first direction, the six clamping heads 11 are further made to contract inward, further increasing the clamping force of the clamping heads 11 on the hexagon head screw, ensuring stable power taking, and preventing the wiring assembly from falling off.
[0048] Optionally, in this embodiment, an internal thread portion 41 is provided inside the limiting sleeve 4, and an external thread portion 14 is provided on the conductive body 1. The limiting sleeve 4 is threadedly connected to the conductive body 1. The limiting sleeve 4 is made of an insulating material. The maintenance personnel hold the insulating inner lining 2 with one hand and manually screw the limiting sleeve 4 with the other hand to make the limiting sleeve 4 move along the first direction, thereby realizing the inward contraction of the plurality of clamping heads 11.
[0049] Optionally, a first anti-slip structure 42 is provided on the outer wall of the limit sleeve 4 to increase the frictional force between the human hand and the limit sleeve 4 and prevent hand slipping. The first anti-slip structure 42 can be, but is not limited to, anti-slip protrusions, anti-slip grooves or anti-slip patterns, etc.
[0050] Optionally, a tapered opening 43 is provided on the inner wall of one end of the limit sleeve 4 close to the clamping head 11, and the inner diameter of the tapered opening 43 gradually decreases in the direction away from the clamping head 11. The tapered opening 43 is located at the front end of the limit sleeve 4, and the internal thread portion 41 is located at the rear end of the limit sleeve 4. By screwing the limit sleeve 4, the tapered opening 43 gradually approaches the outer wall surface of the clamping head 11. As the limit sleeve 4 continues to rotate, the tapered opening 43 can press the opened clamping head 11, causing the clamping head 11 to contract inward and reducing the clamping space 12. Rotating the limit sleeve 4 in the reverse direction causes the clamping head 11 to open outward, thereby loosening the hexagon head screw.
[0051] Optionally, a tapered inclined surface 111 is provided on the outer wall surface of each clamping head 11, and the inner wall surface of the tapered opening 43 abuts against the tapered inclined surface 111. Through the cooperation of the tapered inclined surface 111 and the tapered opening 43, the clamping head 11 can be gradually contracted inward.
[0052] Exemplarily, the conductive body 1 is made of brass. A hexagonal cavity is machined at the head end of the conductive body 1, and six cutting grooves are machined at the vertices of the hexagon to form six clamping heads 11, so that the cavity part has a certain elasticity and can contract inward under an external force; there is a tapered inclined surface 111 on the outer surface of the cavity; an external thread portion 14 is machined at the middle end of the conductive body 1, and a connecting portion 13 is provided further backward.
[0053] Further, as shown in Figure 2 、 Figure 5 、 Figure 6 、 Figure 9 and Figure 10 the fixed sleeve 5 is fixedly sleeved on the insulating lining member 2, the wire 6 passes out from the first wire outlet hole 51, and a second anti-slip structure 52 is provided on the outer wall surface of the fixed sleeve 5. The fixed sleeve 5 is made of an insulating material, and the fixed sleeve 5 with the second anti-slip structure 52 is arranged on the insulating lining member 2 to increase the frictional force between the human hand and the fixed sleeve 5 and prevent hand slipping. The second anti-slip structure 52 can be, but is not limited to, anti-slip protrusions, anti-slip grooves or anti-slip patterns, etc. By adding the first wire outlet hole 51 on the fixed sleeve 5, it is convenient to pass the wire 6 through.
[0054] Optionally, a positioning groove 21 extending in the first direction is provided on the outer wall of the insulating lining member 2, and a positioning rib 53 is provided in the fixed sleeve 5. The positioning rib 53 is inserted into the positioning groove 21 along the first direction. By adding the positioning rib 53 and the positioning groove 21, on the one hand, it guides the installation of the fixed sleeve 5 onto the insulating lining member 2 and improves the installation accuracy, and on the other hand, it limits the rotation of the fixed sleeve 5.
[0055] Furthermore, the wiring assembly further includes a fastener 3. A threaded hole 132 is provided on the outer wall of the connecting portion 13, and a counterbore 22 is provided on the outer wall of the insulating lining 2. A wiring hole 131 is provided inside the connecting portion 13. One end of the wire 6 is inserted into the wiring hole 131. The fastener 3 passes through the counterbore 22 and is connected to the threaded hole 132, and one end of the fastener 3 abuts against and presses the wire 6. In this embodiment, the fastener 3 can be a countersunk screw. After passing through the counterbore 22, the countersunk screw is connected to the threaded hole 132 of the insulating lining 2. Continuing to screw the countersunk screw can press the wire 6 to prevent the wire 6 from becoming loose.
[0056] Optionally, the insulating lining 2 has a receiving cavity 23. A second wire outlet hole 24 and a limiting groove 25 are respectively provided at both ends of the insulating lining 2. Both the second wire outlet hole 24 and the limiting groove 25 communicate with the receiving cavity 23. The connecting portion 13 is inserted into the limiting groove 25. The wire 6 passes through the second wire outlet hole 24 and the receiving cavity 23 and then is inserted into the wiring hole 131. Then, the wire 6 is pressed by the fastener 3 to prevent the wire 6 from falling off.
[0057] Optionally, a first cutting surface 251 is provided on the inner wall of the limiting groove 25, and a second cutting surface 133 is provided on the outer wall of the connecting portion 13. After the connecting portion 13 is inserted into the limiting groove 25, the first cutting surface 251 abuts against the second cutting surface 133 to limit the rotation of the connecting portion 13 and the insulating lining 2 and ensure the connection stability between the two.
[0058] This embodiment also provides a power distribution device, which includes a wiring terminal and the above-mentioned wiring assembly. The wiring assembly is used to clamp the wiring terminal. By using the wiring assembly to clamp the wiring terminal, the wiring terminal can be expanded and tightened in the clamping space formed by multiple clamping heads 11, increasing the contact area between the clamping heads 11 and the wiring terminal, facilitating temporary wiring and power taking, and contributing to safe electricity use.
