[0035] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0036] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.
[0037] Reference Figure 2 and Figure 5 This embodiment provides a wire harnessing mechanism, including a first wire harness 1 and a second wire harness 2. The first wire harness 1 has a first wire-passing hole 31, and the second wire harness 2 includes two clamping arms 21 that are hinged to each other. The two clamping arms 21 can provide clamping force for fixing the first wire harness 1. One of the clamping arms 21 has a second wire-passing hole 32. The first wire-passing hole 31 and the second wire-passing hole 32 are used for passing wires through. The first wire harness 1 and the second wire harness 2 can restrict and constrain the wires passing through them. Both the first wire harness 1 and the second wire harness 2 are made of rigid insulating material, which can protect the operator.
[0038] Specifically, in use, the first wire harness 1 and the second wire harness 2 are respectively installed on different wires through the first wire hole 31 and the second wire hole 32. By controlling the two clamping arms 21 of the second wire harness 2 to clamp the first wire harness 1, the first wire harness 1 and the second wire harness 2 can be fixed together, thereby binding the two corresponding wires and making the wires neatly arranged, avoiding electrical connection problems caused by messy wires. The detachable design between the first wire harness and the first and second wire harnesses allows the staff to flexibly combine and fix the wires according to the actual situation on site.
[0039] Furthermore, in some embodiments, a second wire-passing hole 32 can be opened on both clamping arms 21, so that more wires can be passed through. In some actual operations, the staff can also pass the same wire through the first wire bundle 1 and the second wire bundle 2 to organize the wires and facilitate the neat deployment of the wires.
[0040] Reference Figure 3 , Figure 4 and Figure 5In one embodiment provided in this application: the wire harness mechanism further includes a connecting part 22 for connecting two clamping arms 21. The connecting part 22 includes a connecting shaft 221 and a first elastic member 222. Each clamping arm 21 is provided with a shaft hole 211 adapted to the connecting shaft 221. The two ends of the first elastic member 222 respectively abut against the clamping arm 21. The clamping arm 21 is movably connected to the connecting shaft 221. Each of the two clamping arms 21 has a protrusion 212 on its opposite surface. The two protrusions 212 are staggered and each is provided with a shaft hole 211 adapted to the connecting shaft 221.
[0041] Specifically, the connecting shaft 221 passes through the shaft hole 211 on the two protrusions 212, and the two protrusions 212 are staggered. Both clamping arms 21 are rotatably connected to the connecting shaft 221. The first elastic element 222 is a torsion spring, which controls the same end of the two clamping arms 21 to move closer to each other, and the other ends of the two clamping arms 21 in the same direction will move away from each other. Then, the first wire bundle 1 is placed between the other ends of the two clamping arms 21 and then released. The first elastic element 222 can drive the two clamping arms 21 to clamp the first wire bundle 1, and the first wire bundle 1 and the second wire bundle 2 can be installed together.
[0042] Reference Figure 3 , Figure 4 and Figure 5 In one embodiment provided in this application: a protrusion 11 is provided on the first wire harness 1, the protrusion 11 can be inserted between two clamping arms 21, a first mating part 12 is provided on the protrusion 11, and a second mating part 23 is provided on the opposite surface of one of the clamping arms 21; the shapes of the first mating part 12 and the second mating part 23 are adapted to each other, and when the protrusion 11 is inserted between the two clamping arms 21, the shapes of the second mating part 23 and the first mating part 12 fit together, which can prevent the first wire harness 1 from falling off the second wire harness 2.
[0043] In some embodiments, a second mating part 23 is provided on the opposite surfaces of the two clamping arms 21, and the two second mating parts 23 are arranged symmetrically. Correspondingly, a first mating part 12 is provided on both sides of the protrusion 11 in a symmetrical arrangement. This arrangement can make the installation between the first wire harness 1 and the second wire harness 2 more compact and further prevent the first wire harness 1 and the second wire harness 2 from separating.
[0044] Reference Figure 4 and Figure 5 In one embodiment provided in this application: the second mating part 23 includes a groove 231, the groove 231 includes a guide surface 232 near the side of the protrusion 212, and a limiting surface 233, the limiting surface 233 can prevent the first mating part 12 from falling off between the two clamping arms 21.
[0045] Reference Figure 3 , Figure 4 and Figure 5 In one embodiment provided in this application: the guide surface 232 is inclined, and the side of the guide surface 232 near the other clamping arm 21 is inclined towards the protrusion 212. This design can further simplify the operation steps of installing the first wire harness 1 and the second wire harness 2 together. When installing the wire harness mechanism, it is not necessary to control the clamping arm 21 of the second wire harness 2 to open first. Just align the protrusion 11 of the first wire harness 1 with the two clamping arms 21, and use the shape of the first mating part 12 on the first wire harness 1 and the cooperation of the guide surface 232 on the groove 231 of the second mating part 23 to squeeze the two clamping arms 21 apart. The second wire harness 2 can then clamp the first wire harness 1. Furthermore, due to the setting of the limiting surface 233, the first wire harness 1 can also be prevented from falling off.
[0046] Reference Figure 1 and Figure 6 This embodiment provides a grounding device, including any of the aforementioned wire harnessing mechanisms, and further including: a first conductor 4, one end of which is fixedly connected to a pin 41, and the other end of the first conductor 4 away from the pin 41 is fixedly connected to a coil 5, the coil 5 being spiral-shaped and retractable, providing sufficient operating space for personnel in actual work; a second conductor 6, the second conductor 6 being connected to the first conductor 4 through the coil 5, and the end of the second conductor 6 away from the coil 5 being connected to a wire clamp 7, the wire clamp 7 being used to clamp the grounding body; the first conductor 4 is provided with a wire harnessing mechanism through a first wire hole 31 and a second wire hole 32 respectively, and the second conductor 6 is provided with a first wire harness 1 and a second wire harness 2 through the first wire hole 31 and the second wire hole 32.
[0047] Specifically, the pin 41 is made of conductive copper metal material and can be inserted into the terminal hole to form an electrical connection between the device and the external electrical secondary circuit. The pin 41, the first wire 4, the coil and the second wire 6 and the clamp 7 form an electrical path. The clamp 7 can be clamped on the grounding body to realize the function of grounding the electrical circuit.
[0048] Reference Figure 1 and Figure 6 In some embodiments: the wire clamp 7 includes two clamping rods 71 that are hinged to each other, and a second elastic element 72 is provided between the two clamping rods 71. In this embodiment, the second elastic element 72 is a torsion spring. The clamping rod 71 includes a conductor 711 and an insulating layer 712. The conductor 711 is located inside the clamping rod 71, and the outside of the clamping rod 71 is covered by the insulating layer 712. The insulating layer 712 can protect both the conductor 711 and the operator. The parts of the two clamping rods 71 that are used to clamp the contactor are not covered by the insulating layer 712, so that the wire clamp 7 can conduct electricity by clamping the contactor. The second conductor 6 is fixedly connected to the conductor 711 on one of the clamping rods 71.
[0049] Specifically, when using the clamp 7, control one end of the two clamping rods 71 to move closer to each other, squeeze the second elastic element 72, and move the other ends of the two clamping rods 71 in the same direction away from each other. Releasing the clamping rods 71 will clamp the clamp 7 onto the corresponding grounding body.
[0050] Reference Figure 1 and Figure 6 In some embodiments: a socket 713 is provided on the conductor 711 of one of the clamping rods 71 for inserting a pin 41. Two first wires 4 are provided. The pin 41 of one of the first wires 4 is inserted into the terminal of the external electrical circuit, and the other pin 41 is inserted into the socket 713 on the clamp 7 of another grounding terminal. The first wire harness 1 and the second wire harness 2 of the wire harnessing mechanism are respectively provided on the two first wires 4 to bind the two first wires 4.
[0051] Furthermore, when electrical secondary circuit grounding is required, if the circuit only needs to be grounded at one point, then only one grounding device is needed. The clamp 7 is clamped onto the grounding body, and the pin 41 is connected to the terminal. If multiple circuits need to be grounded, or if the wire length of this device is insufficient, multiple grounding devices are used. The clamp 7 of one grounding device is clamped onto the grounding body, and one pin 41 of each device is inserted into the terminal that needs to be grounded. The other pin 41 is inserted into the pin 41 hole of the clamp 7 of another grounding device, thereby realizing the electrical connection between multiple grounding devices. The wire harness mechanism set on the second conductor 6 can also constrain multiple second conductors 6 when needed.
[0052] Reference Figure 1 In some embodiments: an insulating cap 412 is fitted onto the pin 41, mainly to protect the pin 41. The inner diameter of the insulating cap 412 is the same as the size of the pin 41, and it is made of elastic insulating material. The insulating cap 412 can be removed when the pin 41 needs to be used.
[0053] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
