Description

Technical Field

[0001] This utility model relates to the field of DC drive cabinet technology, and in particular to a DC drive cabinet that is easy to wire. Background Technology

[0002] A DC drive cabinet is an electrical device used to control and regulate the operation of a DC motor. It typically contains various electrical components such as DC power supplies, contactors, relays, resistors, capacitors, current and voltage sensors, etc.

[0003] DC drive cabinets are widely used in industrial automation, transportation, mining machinery, and lifting equipment, especially in applications requiring precise control of motor speed and torque. For example, Chinese Patent Publication No. "CN222301165U" provides a DC drive cabinet that facilitates wiring, comprising: a cabinet body with a movable slot on one side of its interior; a cabinet door on one side of the cabinet body; an opening and closing mechanism on one side of the cabinet door; a fixed plate inside the cabinet body, with a threaded hole on one side and a threaded hole on the front; and a movable mechanism on one side of the fixed plate. This invention achieves the effect of adjusting the position of the fixed plate and the U-shaped fixing frame by rotating a rotating block, which in turn moves a threaded rod. When the threaded rod leaves the threaded hole, the position of the fixed plate can be adjusted. Similarly, rotating a rotating block moves a threaded rod, which in turn moves the U-shaped fixing frame. This allows for adjustment of the fixed plate and the U-shaped fixing frame according to the length of the wiring.

[0004] Currently, most DC drive cabinets have a large number of internal electrical components. When connecting the circuits, if the circuits are arbitrarily stuffed into the cabinet after being powered on, the circuits will be too long and will not only become tangled and knotted, but also squeezed together, which can easily cause the circuits to break. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing a DC drive cabinet that facilitates wiring.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0031] A cable tie 15 is attached to the front of the accessory plate 13. A pull head 16 is provided at the outward end of the cable tie 15. The connection between the pull head 16 and the cable tie 15 is fixed by welding. A cable tie channel 17 is provided on the inner side of the cable tie 15 along the upper end.

[0032] The front of the accessory plate 13 is provided with a winding drum 2. One end of the winding drum 2 is welded to the accessory plate 13. The winding drum 2 and the wire harness seat 15 are arranged in a one-to-one correspondence. The inside of the winding drum 2 is provided with an internal thread. The internal thread of the internal thread is connected to a threaded rod 21. A disc 22 is fixed to the outward end of the threaded rod 21. Two symmetrically distributed arc-shaped plates 23 are fixed to the side of the disc 22 near the winding drum 2.

[0033] It should be further noted that the mounting slots 14 are distributed in a rectangular array, and the mounting slots 14 are circular slots. The inner wall of the mounting slots 14 is smooth or threaded. The mounting slots 14 can be assembled and fixed by screws or bolts when the component is installed.

[0034] It should be further explained that the cable tie 15 has an internal groove 1001. A square sleeve 1004 is provided on the inner side of the internal groove 1001 along the port position. The connection position between the square sleeve 1004 and the internal groove 1001 is fixed by screws. The square sleeve 1004, relative to the anti-detachment plate 1002, allows the cable tie 15 to have an anti-detachment effect when pulled.

[0035] It should be further explained that an anti-detachment plate 1002 is slidably sleeved inside the built-in groove 1001. A square rod 1003 is provided at one end of the anti-detachment plate 1002. One end of the square rod 1003 is fixed to the anti-detachment plate 1002 by screws. The other end of the square rod 1003 is welded to the surface of the accessory plate 13. The surface of the square rod 1003 is slidably sleeved with the inner side of the square sleeve 1004. Through the sleeve of the square rod 1003 and the square sleeve 1004, and based on the shape limitation, the cable tie seat 15 can have a horizontal movement effect during the pulling or resetting process, ensuring the stability of the cable tie process.

[0036] It should be further noted that a spring 1005 is provided inside the built-in slot 1001. The spring 1005 is wound around the surface of the square rod 1003. The two ends of the spring 1005 are fixedly installed to the end face of the square sleeve 1004 and the end face of the anti-detachment plate 1002, respectively. The spring 1005 can facilitate the reset of the cable tie 15 after stretching, ensuring that after multiple lines pass through the cable tie channel 17, the cable tie 15 can stably position the cable tie on the accessory plate 13.

[0037] It should be further explained that threaded posts 31 are provided on the inner wall of the cabinet 11. The threaded posts 31 are arranged horizontally, and there are at least four sets of threaded posts 31, which are distributed along the four top corners of the cabinet 11. A connecting sleeve 3 is provided through the surface of the insulating plate 12. The connecting sleeve 3 is fixed to the insulating plate 12 by welding. The surface of the threaded post 31 is slidably fitted with the inner ring wall of the connecting sleeve 3. When it is necessary to remove the insulating plate 12 together with the accessory plate 13 from the cabinet 11, the connecting sleeve 3 and the threaded post 31 can be slid apart to separate the insulating plate 12 from the cabinet 11.

[0038] It should be further explained that the threaded post 31 has a nut 32 threadedly connected to its surface. One end of the nut 32 is tightly fitted against the end face of the connecting sleeve 3. The outer ring wall of the nut 32 has a hexagonal structure. When it is necessary to remove the insulating plate 12 as a whole, the nut 32 is rotated to separate it from the threaded post 31, thus realizing the connection sleeve 3.

[0039] It should be further noted that cable sleeves 4 are installed through both sides of the cabinet 11. The connection between the cable sleeves 4 and the cabinet 11 is fixed by welding. The cable sleeves 4 can collect the circuits on one side of the cabinet 11 and bring them out from the cabinet 11, which is convenient for the accessories to be connected to external electrical appliances or power sources.

[0040] It should be further noted that the cabinet 11 has a door 5 hinged to the front, and a heat dissipation vent 51 is provided on the back of the cabinet 11 near the lower end, which runs through the interior. The door 5 can close the opening of the cabinet 11, and the heat dissipation vent 51 can provide heat dissipation and ventilation when the internal components of the cabinet 11 are working.

[0041] Working method: By installing the insulating plate 12 and the accessory plate 13, a supporting structure for a component can be formed. The cable tie 15 structure is set on both sides of the accessory plate 13. The wires connected to multiple accessories can be concentrated in the cable tie channel 17 of the cable tie 15 and led out to one side. When operating the cable tie 15, the cable tie 15 can be pulled by the pull head 16. Through the stretching effect of the spring 1005, the cable tie 15 is pulled away from the accessory plate 13 and pulled outward, exposing the cable tie channel 17 and inserting each wire into the cable tie channel 17. After the wires are concentrated and guided, through the reset effect of the spring 1005, the cable tie 15 can re-contact with the accessory plate 13, so that the cable tie channel 17 is closed again in a ring shape, completing the concentrated cable tie management of multiple wires.

[0042] When it is necessary to wind up and store the wire that is too long, the wire led out from the single wire harness 15 can be wound onto the winding drum 2 for winding and storage. The threaded rod 21 is threadedly connected to the internal thread of the winding drum 2, which can realize the positioning of the disc 22 and the winding drum 2. The two arc plates 23 can wrap the wound wire. The interval between the two arc plates 23 can serve as the wire inlet and the wire outlet, respectively.

[0043] When it is necessary to remove the insulation board 12 and the accessory board 13 together from the cabinet 11, the insulation board 12 can be separated from the cabinet 11 by sliding the connecting sleeve 3 and the threaded post 31. Rotating the nut 32 will separate it from the threaded post 31, thus separating the connecting sleeve 3.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
