Abstract
Description
Technical Field
[0001] This utility model relates to a wiring device for an electric motor, and more particularly to a wiring device for a new energy vehicle motor applied in the field of new energy vehicle technology. Background Technology
[0002] New energy vehicles are driven entirely by electricity as a clean energy source. The motor is connected to the battery of the new energy vehicle through various cables. The motor is driven by charging the battery, thereby driving the vehicle to move. The driving ability of a new energy vehicle depends on the power of the motor, so the motor has become one of the core components of a new energy vehicle.
[0003] Chinese patent CN212850092U discloses a wiring device for a new energy vehicle motor, including a box body. Inside the box body, a pair of downward pressing blocks are fixed at the bottom and arranged in a left-right pattern. An upper pressing block is provided on the upper end of the two downward pressing blocks, which solves the problem that current wiring devices for new energy vehicle motors are not convenient for neatly laying cables and core wires.
[0004] During vehicle operation, factors such as bumps and vibrations can easily cause wiring to become loose, leading to poor circuit contact and affecting the normal operation of the motor. Utility Model Content
[0005] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is that during the vehicle's operation, due to factors such as bumps and vibrations, the wiring is prone to loosening, which leads to poor circuit contact and affects the normal operation of the motor.
[0006] To address the aforementioned issues, this utility model provides a wiring device for a new energy vehicle motor, comprising a junction box with multiple through holes on its side for threading wires. A sliding groove is detachably connected to the side of the junction box near the through holes, and a slide rail is fixedly connected within the groove. A telescopic rod is slidably connected to the slide rail via a slider. A connecting block is fixedly connected to the movable end of the telescopic rod, and a compression spring is fitted onto the surface of the telescopic rod. A clamp is fixedly connected to the end of the connecting block away from the telescopic rod, and the clamp is in contact with the surface of the threaded wire. Extension plates are symmetrically fixedly connected to the upper and lower ends of the clamp. A bidirectional sliding rod is detachably connected between two symmetrical extension plates located on either side of the threaded wire, and a first nut is fitted onto the surfaces of both the movable and fixed ends of the bidirectional sliding rod.
[0007] In the above-mentioned wiring device, the clamp is fixed to the surface of the connecting wire, thereby entering the limiting position of the connecting wire. At the same time, in conjunction with the telescopic rod and compression spring, when the new energy vehicle generates pulling vibration during driving, the connecting wire near the interface can be tensioned and adjusted to avoid the phenomenon of loosening and falling off at the interface.
[0008] As a further improvement of this application, a through hole is provided on the extension plate, and a threaded ring is fixedly connected to the outer ring of the through hole on the side of the extension plate near the connecting block, and the bidirectional slide rod passes through the through hole and is fixed by the second nut and the threaded ring.
[0009] As a further improvement to this application, a protective pad is fixedly connected to the end of the clamp away from the connecting block by glue, and both the protective pad and the clamp are made of silicone.
[0010] As a further improvement of this application, a sealing ring is fixedly connected to the inner wall of the wire hole by adhesive, and the sealing ring is fitted onto the surface of the wire and adheres to it.
[0011] As another improvement of this application, a limiting ring is fixedly connected to one end of the sealing ring outside the wire hole, a protective cover is fitted on the wire hole, and an elastic ring is installed at the end of the protective cover that is engaged with the limiting ring.
[0012] As a further improvement to this application, the slide is fixed to the junction box by screws and threads, and the slide is designed in various lengths.
[0013] As a further improvement to this application, the slide has a sliding opening, and a baffle is fixed to the side end of the sliding opening by screws.
[0014] In summary, after inserting the connecting wire into the wiring hole and connecting it to the components inside the junction box, select a suitable length of slide groove according to the distance between two adjacent wiring holes, and install it on the side of the wiring hole with screws. Then, install the clamps on the slide rail inside the slide groove through the sliding opening at the side end of the slide groove using the slider. After that, close the sliding opening with the baffle. At this time, install the bidirectional slide rod between two adjacent extension plates, and engage the two clamps with the surface of the connecting wire through the extension and retraction of the bidirectional slide rod. After it is completely in contact with the surface of the connecting wire, tighten the first nut to fix the movable end of the bidirectional slide rod, thereby fixing the position of the connecting wire. At this time, when the new energy vehicle vibrates and pulls on the junction box and connecting wire during driving, the tension of the connecting wire can be adjusted by the limiting of the clamps, combined with the buffer of the extension rod and the compression spring.

Detailed Implementation
[0024] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0025] First implementation method:
[0026] Figures 1-4 A wiring device for a new energy vehicle motor is shown, including a junction box 1. The junction box 1 has multiple wire holes 14 on its side, through which a connecting wire 2 is threaded. A sliding groove 4 is detachably connected to the side of the junction box 1 at the side of the wire holes 14. A slide rail 10 is fixedly connected in the sliding groove 4. A telescopic rod 7 is slidably connected to the slide rail 10 via a slider 9. A connecting block 6 is fixedly connected to the movable end of the telescopic rod 7, and a compression spring 8 is sleeved on the surface of the telescopic rod 7. A clamp 5 is fixedly connected to the end of the connecting block 6 away from the telescopic rod 7, and the clamp 5 is in contact with the surface of the connecting wire 2. Extension plates 3 are symmetrically fixedly connected to the upper and lower ends of the clamp 5. A bidirectional slide rod 11 is detachably connected between two symmetrical extension plates 3 on both sides of the connecting wire 2, and a first nut 12 is sleeved on the surface of both the movable and fixed ends of the bidirectional slide rod 11.
[0027] The extension plate 3 has a through hole. A threaded ring 20 is fixedly connected to the side of the extension plate 3 near the connecting block 6 at the outer ring of the through hole. The bidirectional slide rod 11 passes through the through hole and is fixed by the second nut 19 and the threaded ring 20. The slide groove 4 is fixed to the junction box 1 by screws. The slide groove 4 is designed with multiple lengths. The slide groove 4 has a sliding opening. A baffle is fixed to the side end of the sliding opening by screws.
[0028] Working principle: After the connecting wire 2 is inserted into the wire hole 14 and connected to the components in the junction box 1, a suitable length of slide groove 4 is selected according to the distance between two adjacent wire holes 14. The slide groove 4 is installed on the side of the wire hole 14 with screws. The clamp 5 is installed on the slide rail 10 in the slide groove 4 from the sliding opening at the side end of the slide groove 4 through the slider 9. Then the sliding opening is closed by the baffle. At this time, the bidirectional slide rod 11 is inserted into the through hole between two adjacent extension plates 3 and fixed by the second nut 19. The two clamps 5 are engaged with the surface of the connecting wire 2 by the extension and retraction of the bidirectional slide rod 11. After they are fully in contact with the surface of the connecting wire 2, the first nut 12 is turned to fix the movable end of the bidirectional slide rod 11, thereby fixing the position of the connecting wire 2. At this time, when the new energy vehicle vibrates and pulls the junction box 1 and the connecting wire 2 during driving, the clamp 5 can be used for limiting, and the extension rod 7 and the compression spring 8 can be used for buffering, so that the tension of the connecting wire 2 can be adjusted.
[0029] The clamp 5 is fixed to the surface of the connecting wire 2, thereby limiting the connecting wire 2. At the same time, in conjunction with the telescopic rod 7 and the compression spring 8, when the new energy vehicle is pulled and vibrated during driving, the connecting wire 2 near the interface can be tensioned and adjusted to prevent the interface from becoming loose and falling off.
[0030] Second implementation method:
[0031] Figures 5-7 The clamp 5 is shown to be fixedly connected to a protective pad 13 by glue at the end away from the connecting block 6. Both the protective pad 13 and the clamp 5 are made of silicone. A sealing ring 15 is fixedly connected to the inner wall of the wire hole 14 by glue. The sealing ring 15 is fitted onto the surface of the connecting wire 2 and fits thereto. A limit ring 17 is fixedly connected to the end of the sealing ring 15 outside the wire hole 14. A protective cover 16 is fitted on the wire hole 14. An elastic ring 18 is installed at the end of the protective cover 16 that is engaged with the limit ring 17.
[0032] Working principle: Before the connecting wire 2 passes through the wire hole 14, the sealing ring 15 is installed on the inner wall of the wire hole 14 with glue. At this time, the limiting ring 17 is located at the wire hole 14 and is attached to the side wall of the junction box 1. Then, the protective cover 16 is put on the surface of the connecting wire 2 and the connecting wire 2 is connected to the wire hole 14. At this time, the sealing ring 15 is attached to the surface of the connecting wire 2, which has a sealing and waterproof effect on the wire hole 14. Then, the protective cover 16 is adjusted. One end is engaged with the limiting ring 17 through the elastic ring 18, and the other end is attached to the surface of the connecting wire 2 through the elastic ring 18. This can protect the parts installed outside the wire hole 14 and avoid the problem of difficulty in disassembly after long-term use due to corrosion. Then, the protective pad 13 is fixed to the clamp 5 with glue. When the clamp 5 is attached to the surface of the connecting wire 2, the protective pad 13 can play an anti-slip role. At the same time, the protective pad 13 can be easily replaced when it is severely worn during long-term use.
[0033] By installing a sealing ring 15 on the inner wall of the wire hole 14, a sealing and waterproofing effect can be achieved. At the same time, a protective cover 16 is installed on the surface of the parts installed outside the wire hole 14 to protect them and prevent corrosion.
[0034] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
