Description

Technical Field

[0001] This utility model belongs to the field of cable management technology, specifically relating to a cable management mechanism suitable for use in power distribution cabinets. Background Technology

[0002] Cable management devices / mechanisms are accessories installed inside the cabinets of electrical distribution cabinets to straighten and secure wires, ensuring they are neatly and orderly routed inside and outside the cabinet, resulting in a more aesthetically pleasing and standardized cable routing. Existing cable management mechanisms installed in electrical distribution cabinets mainly consist of junction boxes and end caps attached to the junction boxes. The inner rear wall of the junction box has one or more rows of cable management sections, and the upper and lower walls of the junction box have through grooves corresponding to these sections. Wires / cables pass through these grooves and are routed between the junction box and the outside, with the cable management sections providing a secure connection. To ensure the end caps can reliably and securely cover the junction boxes, a sliding mechanism is often used between the end caps and the junction boxes. This allows the end caps to slide laterally off the junction boxes for wiring operations while effectively preventing them from detaching or falling off.

[0003] Because the cable management mechanism is fixed inside the distribution cabinet, when the end cover and the junction box are matched using a sliding structure, the overall length of the cable management mechanism is limited by the need to allow sliding distance / space for the end cover. This generally results in a relatively short length, unable to support a large amount of fixed cabling, and thus failing to meet practical needs. While using a hook-and-loop connection between the end cover and the junction box can overcome the aforementioned problems and increase the length of the cable management mechanism, it still presents inconvenience in removing the end cover from the junction box and fixing it to the junction box. Utility Model Content

[0004] The cable management mechanism provided by this utility model, which is suitable for use in power distribution cabinets, can overcome the limitation on the length of the cable management mechanism caused by the fit structure between the end cover and the junction box, thus allowing the length of the cable management mechanism to be increased.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a cable management mechanism suitable for use in a power distribution cabinet, including a cable box, at least one end cover, and multiple flexible connection components.

[0006] At least one row of wire harnesses is provided on the rear wall of the junction box. Through slots are provided on the upper and lower walls that are vertically opposite to the wire harnesses. Wires extend into and out of the junction box through the through slots and are matched with the wire harnesses.

[0007] The end cap includes a cover plate body and two side plates respectively located on the upper and lower ends of the cover plate body.

[0008] The elastic connecting components are located between the cover plate body and the side plates, fixing them together and allowing the side plates to reciprocate vertically relative to the cover plate body. Multiple elastic connecting components are typically installed on both the upper and lower sides between the cover plate body and the side plates to connect them and allow for reciprocating relative movement. Finger grooves are provided on the outer surface of the side plates. During operation, fingers are inserted into the finger grooves on the two opposing side plates, and squeezing causes the side plates to move closer to the cover plate body; after releasing the squeezing force, the elastic connecting components allow the side plates to move away from the cover plate body and return to their original position.

[0009] The flexible connection assembly includes a connecting rod with one end mating and connecting to the cover plate body, and the other end fixedly inserted into a multi-stage through hole provided on the side plate body, with the end protruding from the multi-stage through hole. Correspondingly, straight grooves extending along the length direction of the wire box are respectively provided on the upper and lower wall surfaces at the port of the wire box.

[0010] The end of the connecting rod protruding outside the multi-stage through hole can be selectively inserted into and removed from the straight groove during the movement of the side plate relative to the cover plate body, and can fix the end cover at the port of the box and remove it from the port.

[0011] Optionally, the resilient connection assembly further includes a spring and a stopper. The stopper is fixed to the cover plate body and has a vertically oriented hole. The connecting rod includes end rod one and end rod two respectively located at its two ends.

[0012] End rod one is inserted into and matched with a multi-stage through hole, and can fix the connecting rod to the side plate together. End rod two is inserted into a shaped hole on the plug, and a nut is provided at its end, so that end rod two can move vertically relative to the plug and the free end can be confined in the shaped hole. A spring is sleeved on end rod two, and one end of it directly or indirectly contacts the end face of the side plate, and the other end contacts the end face of the plug.

[0013] Optionally, an elastic rubber ring is provided at one end of the nut component facing the bottom surface of the bore.

[0014] Optionally, the cover plate body has a threaded countersunk hole that corresponds to the plug. The plug and the threaded countersunk hole are detachably connected, thus fixing the plug to the cover plate body.

[0015] Optionally, the connecting rod is fixedly connected to one end of the multi-stage through hole by a threaded structure, and the end of the rod passing through the multi-stage through hole protrudes from the other end of the multi-stage through hole.

[0016] Optionally, the end of the connecting rod exposed at the multi-stage through hole is formed into a conical annular surface, and the small diameter end of the conical annular surface is a free end; the outer diameter at the root of the conical annular surface is consistent with the width of the straight groove.

[0017] Optionally, a limiting block is provided on the upper and lower walls at the port of the wire box, and on the inner side of the straight groove. A flange is provided on the inner side of the side plate, and on the side opposite to the main body of the cover plate. When the end cover is fastened to the port of the wire box, the flange can extend into the wire box and contact the limiting block, so that the end of the connecting rod is vertically aligned with the straight groove, allowing it to be smoothly inserted into and removed from the straight groove.

[0018] Optionally, there are multiple end caps at the port of the box, and these multiple end caps are arranged and connected in sequence.

[0019] Optionally, at least one layer of elastic rubber strip extending vertically is provided on the front and rear end faces of the end cap.

[0020] The beneficial effects of this utility model are as follows: This utility model can solve the problem in the prior art where the cable management mechanism uses a sliding structure to establish a matching relationship between the end cover and the junction box, which restricts the length of the cable management mechanism and prevents its effective increase within the distribution cabinet, thus failing to meet practical needs. This utility model, by optimizing and improving the matching structure between the end cover and the junction box, can effectively increase the overall length of the cable management mechanism installed in the distribution cabinet, meeting the actual demand for more wiring. Simultaneously, it allows for convenient fixing and removal of the end cover from the junction box. Attached Figure Description

[0027] The structures, proportions, and sizes shown in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art. They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, terms such as "upper," "lower," "front," "rear," and "middle" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0028] like Figures 1 to 5 The cable management mechanism shown, suitable for use within a distribution cabinet, includes a cable box 10, multiple end caps 20, and multiple flexible connection components 30. See below. Figure 1 As shown, multiple end caps 20 are arranged side by side in the front-to-back direction, which can cover the (left) port of the junction box 10. By controlling the connection state between some end caps 20 and the junction box 10, different positions of the left port of the junction box 10 can be selectively opened.

[0029] like Figures 1 to 4 As shown, multiple rows of vertically alternating wire harnesses 111 are arranged on the rear wall 11 of the junction box 10. Through slots 12, vertically opposite to the wire harnesses 111, are provided on the upper and lower walls of the junction box 10. The wire 100 extends into the junction box 10 through one through slot 12, is fixedly connected to the wire harness 111, and then extends out of the junction box 10 through the other through slot 12. The wire harness 111 may include a clamp for fixing the wire 100, as shown in the figure. Figure 2 It may also contain multiple clamps for securing the wire 100, and these clamps may be distributed in the left-right direction. A sealing body 121 made of elastic material is provided within the through groove 12, and the sealing body 121 may be a bristle body or a sponge body. The wire 100 can pass through the center of the sealing body 121. The technical content involved in this section can be implemented with reference to existing technology and will not be elaborated further.

[0030] In this application, each end cap 20 includes a cover plate body 21 and two side plates 22 respectively disposed on the upper and lower ends of the cover plate body 21.

[0031] The cover plate body 21 and the two side plates 22 are connected together by multiple elastic connecting components 30, allowing both side plates 22 to reciprocate vertically relative to the cover plate body 21. Each side plate 22 has a finger groove 24 on its outer surface, and the number of finger grooves 24 on the two opposing side plates 22 can be the same or different. During operation, inserting fingers into the finger grooves 24 on the upper and lower side plates 22 and squeezing them causes the two side plates 22 to move towards the side / direction of the cover plate body 21; conversely, releasing the squeezing force allows the two side plates 22 to move away from the cover plate body 21 under the elastic force of the elastic connecting components 30, thus resetting their original position.

[0032] The elastic connecting assembly 30 includes a connecting rod 31, one end of which is matched and connected to the cover plate body 21, and the other end is fixedly inserted into a multi-stage through hole 221 provided on the side plate body 22, with the end protruding from the multi-stage through hole 221. It should be further emphasized that the end of the connecting rod 31 connected to the cover plate body 21 allows the side plate body 22 to reciprocate relative to the cover plate body 21. The end of the connecting rod 31 inserted into the side plate body 22 establishes a relatively fixed connection with the side plate body 22. The elastic connecting assembly 30 may also include a spring 32 and a stopper 33. The stopper 33 is fixed to the cover plate body 21 and has a shaped hole in the vertical direction.

[0033] Corresponding to the end of the connecting rod 31 in the elastic connection assembly 30 that protrudes to the upper or lower end face of the side plate 22, straight grooves 14 extending along the length direction of the wire box 10 are respectively provided on the upper and lower wall surfaces at the port of the wire box 10. This allows the end of the connecting rod 31 to be inserted and matched with the straight groove 14. Specifically, The end of the connecting rod 31 protruding from the multi-stage through hole 221 can be selectively inserted into and removed from the straight groove 14 during the reciprocating movement of the side plate body 22 relative to the cover plate body 21, thereby achieving the purpose of fixing the end cover 20 at the port of the wire box 10 and removing it from the port.

[0034] The connecting rod 31 includes a first end rod 311 and a second end rod 312 respectively located at its two ends. The first end rod 311 is inserted into the multi-stage through hole 221 and can fix the connecting rod 31 to the side plate 22 together. The free end of the first end rod 311 protrudes outside the multi-stage through hole 221. The second end rod 312 is inserted into a shaped hole provided on the plug 33, and a nut 313 is provided at its end, so that the second end rod 312 can move vertically relative to the plug 33 and the free end of the second end rod 312 can be confined in the shaped hole.

[0035] The spring 32 is sleeved on the end rod 312, and one end of the spring 32 is in direct or indirect contact with the end face of the side plate 22, while the other end is in contact with the end face of the plug 33. When the end rod 312 moves vertically relative to the plug 33, the spring 32 can undergo expansion and contraction deformation.

[0036] An elastic rubber ring 314 is provided at one end of the nut 313 facing the bottom surface of the hole, which serves as a buffer / shock absorber.

[0037] The cover plate body 21 is provided with a threaded countersunk hole 211 that corresponds to and matches the plug 33. The plug 33 and the threaded countersunk hole 211 are matched with a threaded structure, thus establishing a detachable connection with the cover plate body 21.

[0038] The connecting rod 31 is fixedly connected to one end of the multi-stage through hole 221 by a threaded structure, and after the end rod 311 passes through the multi-stage through hole 221, its free end protrudes from the other end of the multi-stage through hole 221 to match the straight groove 14.

[0039] To ensure that the end of the connecting rod 31 (or the end rod 311) can be smoothly inserted into the straight groove 14, the end of the connecting rod 31 (or the end rod 311) protruding from the multi-stage through hole 221 is formed into a tapered annular surface, with the smaller diameter end of the tapered annular surface being a free end. The outer diameter at the root of the tapered annular surface is the same as the width of the straight groove 14. The outer diameter at the root of the tapered annular surface can also be the same as the outer diameter of the end rod 311.

[0040] To ensure accurate and quick connection between the end cap 20 and the junction box 10, a limiting block 13 is provided on the upper and lower walls at the port of the junction box 10, inside the straight groove 14. Correspondingly, a flange 25 is provided on the inner side of the side plate 22, at the end opposite to the cover plate body 21.

[0041] When the end cap 20 is fastened to the port of the junction box 10, the edge plate 25 can extend into the junction box 10 and contact the limiting block 13, so that the end of the connecting rod 31 is vertically aligned with the straight groove 14. After the pinching pressure applied to the side plate 22 is removed, the end of the connecting rod 31, or the end of the end rod 311, can be accurately inserted into the straight groove 14.

[0042] On the outer surface of the side plate 22 (see as shown) Figure 3 On the left side shown), and on the side opposite to the cover plate body 21 ( Figure 3 The image shown is of the upper end; if it is a side plate 22 located at the lower part of the cover plate body 21, then it is of the lower end. An elastic protrusion 26 is provided at the edge of the protrusion. The top surface of the elastic protrusion 26 is inclined, and the outer end of the elastic protrusion 26 (…) Figure 3 The left side (as shown) protrudes from the (upper or lower) end face of the side plate 22. That is, the inclined surface is on... Figure 3 Extending along the left and right direction. Thus, after the end cap 20 is inserted into the port of the wire box 10 and the pinching pressure applied to the side plate 22 is released, as the (upper and lower) end faces of the side plate 22 come into contact with the inner wall surface at the port of the wire box 10, the elastic protrusion 26 can be squeezed, which helps to establish a stable matching relationship between the side plate 22 and the wire box 10, making it less prone to shaking and noise when subjected to vibration.

[0043] Multiple end caps 20 are sequentially arranged and connected at the port of the junction box 10. At this time, at least one layer of elastic rubber strip 23 extending vertically can be provided on the front and rear end faces of each end cap 20. After the multiple end caps 20 are fixed at the port of the junction box 10, the elastic rubber strip 23 between the opposing surfaces of two adjacent end caps 20 can be simultaneously compressed, producing elastic deformation, thus forming a flexible fixed connection between adjacent end caps 20, which can resist vibration and reduce noise. Specifically, as shown... Figure 4 As shown, two layers of elastic rubber strips 23 extending vertically are provided on the front and rear end surfaces of the cover plate body 21, and one layer of elastic rubber strip 23 extending vertically is provided on the front and rear end surfaces of the side plate body 22.

[0044] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit it. Many aspects of this utility model can be improved without departing from the overall concept. Those skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
