Description

Technical Field

[0001] This invention relates to the field of photovoltaic grid-connected cabinet technology, specifically to a wire harness installation structure and a photovoltaic grid-connected cabinet. Background Technology

[0002] Photovoltaic grid-connected cabinets typically need to integrate various wiring harnesses, including DC input cables, AC output cables, communication control lines, grounding wires, and auxiliary power lines. These wiring harnesses vary greatly in wire diameter and function, and all require high levels of ease of maintenance.

[0003] Currently, the industry generally uses traditional wire harness fixing methods, such as using plastic cable ties, fixed PVC cable trays, or metal wire clamps installed with screws for restraint.

[0004] However, once the cable ties are tightened, they cannot be reversed. When repairing or replacing cables, they need to be cut and re-tied. The position of the fixed cable tray is not adjustable, making it difficult to adapt to different projects or later expansion needs, which leads to an extended construction period. Summary of the Invention

[0005] The purpose of this invention is to provide a wiring harness installation structure and a photovoltaic grid-connected cabinet to solve the problems mentioned in the background art, such as the inconvenience of replacing or repairing wiring harnesses once they are fixed, and the difficulty in adapting to different projects or subsequent capacity expansion needs.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wire harness mounting structure, comprising: The cabinet has an inlet hole on one side of its lower end for the wire harness to enter, and electrical components are fixedly installed inside the cabinet. The conduit is detachably fixed inside the inlet hole and is used to adjust and fix the direction of multiple wire harnesses entering the cabinet. A flexible, magnetically adsorbed rubber strip is attached to the inner wall of the cabinet. An elastic metal slide is provided on one side of the inner end of the rubber strip. A positioning component is provided on the rubber strip. The positioning component is provided with a plurality of elastic clamping plates that can move on the elastic metal slide. The elastic clamping plates are used to clamp the wire harness connected to the electrical components.

[0007] The present invention also has the following technical features: In one embodiment of the present invention, one end of the conduit extends out of the outside of the cabinet and is provided with a fixing structure, which is used to separate and fix multiple sets of wire harnesses passing through the conduit.

[0008] In one embodiment of the present invention, the rubber strip is a flexible rubber, and an elastic sheet is fixedly installed on the outer end of the other side of the rubber strip. A plurality of strip-shaped notches are evenly opened on one end of the elastic sheet, and the bottom end of the rubber strip is attracted to the inner wall of the cabinet in a curved or straight shape by a first permanent magnet.

[0009] In one embodiment of the present invention, the conduit includes a metal telescopic tube, one end of which is fixedly installed with a first external threaded tube, and the other end is located at the outer end of the cabinet. The outer end of the metal telescopic tube is covered with flame-retardant silicone.

[0010] In one embodiment of the present invention, a first retaining ring is fixedly installed on the outer wall of the first external threaded tube, and a sealing ring is fixedly installed on one side wall of the first retaining ring. The first external threaded tube passes through the inlet hole and is threadedly connected to a fixing nut. When the fixing nut is screwed onto the outer wall of the first external threaded tube, the sealing ring adheres to the outer wall of the cabinet.

[0011] In one embodiment of the present invention, the fixing structure includes a first internal threaded tube fixed to the other end of the metal telescopic tube, a second external threaded tube being threadedly connected to the end of the first internal threaded tube away from the metal telescopic tube, the outer end of the second external threaded tube being closed, and a plurality of second internal threaded tubes being uniformly fixedly installed, and the second internal threaded tubes being threadedly connected to a sealing structure.

[0012] In one embodiment of the present invention, a second retaining ring is fixedly installed on the outer wall of the second external threaded tube, and a sealing ring is fixedly installed on the outer end of the second retaining ring. The outer wall of the second external threaded tube is threadedly connected to the inner wall of the first internal threaded tube, and the second retaining ring is in close contact with the outer end side wall of the first internal threaded tube through the sealing ring.

[0013] In one embodiment of the present invention, the sealing structure includes a third external threaded tube or sealing block that is threadedly connected to the outer end of a second internal threaded tube. A tapered threaded sleeve is fixedly installed on the outer end of the third external threaded tube, and a rubber sleeve is provided on the inner end of the third external threaded tube. A plurality of strip-shaped holes are evenly opened on the outer end of the tapered threaded sleeve. A rubber pad is fixedly installed on the inner wall of the tapered threaded sleeve and is sleeved on the outer end of the wire harness through the rubber pad. An adjusting nut that is threadedly connected to the tapered threaded sleeve is sleeved on the outer end of the wire harness.

[0014] In one embodiment of the present invention, the positioning component includes a plurality of sliders, the sliders being slidably disposed within an elastic metal slide rail, both the sliders and the elastic metal slide rail having convex cross-sections, the upper end of the sliders sliding out of the elastic metal slide rail and being rotatably connected to a base plate via a rotating component, and elastic clamping plates being symmetrically fixedly installed on the left and right sides of the upper end of the base plate.

[0015] In one embodiment of the present invention, a positioning limiting structure is fixedly installed on one side of the upper end of each slider. The positioning limiting structure includes an extension plate that is vertically fixed on one side of the upper end of the slider. The extension plate is located above the elastic sheet. A rotating rod is rotatably connected to the lower end of the extension plate. A second permanent magnet is rotatably connected to one end of the rotating rod. The second permanent magnet can be attracted to the upper end of the elastic sheet.

[0016] A photovoltaic grid-connected cabinet includes the aforementioned wiring harness mounting structure.

[0017] Compared with the prior art, the beneficial effects of the present invention are: By employing a sliding, lockable elastic clamping plate and rubber strip structure, the wiring harness fixing position can be adjusted arbitrarily along the track, enabling quick one-handed installation and disassembly without the need for pre-drilling or tools. During maintenance or expansion, the entire wiring harness assembly can be removed simply by pulling the clamping plate outward, significantly shortening construction and maintenance time.

[0018] The rubber strips are arranged to fit against the inner wall of the cabinet, taking up far less space than traditional enclosed cable trays. The cable bundles are arranged in an open manner, allowing for smooth airflow, which is conducive to heat dissipation and reduces local temperature rise. This is especially suitable for high power density photovoltaic grid-connected scenarios.

[0019] A conduit is fixedly installed at the wire harness entrance. The metal telescopic tube can automatically adjust its direction according to the bending angle of the wire harness and fix the wire harness, thereby improving the stability of the wire harness installation.

[0022] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1 to 10This invention provides a technical solution: a wire harness installation structure, comprising: a cabinet 10, with an inlet hole on one side of the lower end of the cabinet 10 for wire harnesses 213 to enter; electrical components are fixedly installed inside the cabinet 10; multiple sets of wire harnesses 213 enter the cabinet 10 through the inlet hole and are respectively fixedly connected to different electrical components; a conduit 20, detachably fixed in the inlet hole, used to adjust and fix the direction of the multiple sets of wire harnesses 213 entering the cabinet 10, automatically adjusting the direction according to the bending angle of the wire harness and fixing the wire harness, thereby improving the stability of the wire harness installation; a rubber strip 301, which is bendable and magnetically adsorbed onto the inner wall of the cabinet 10; an elastic metal slide 302 is provided on one side of the inner end of the rubber strip 301; the rubber strip 301 is made of flexible rubber; an elastic sheet 303 is fixedly installed on the outer end of the other side of the rubber strip 301; one end of the elastic sheet 303 is evenly provided with several strip-shaped notches 304; the elastic sheet 303 can adjust the direction of the rubber strip 301. The elastic sheet 303 has several strip-shaped notches 304 evenly distributed on one side, giving it good bending ability. The bottom end of the rubber strip 301 is attracted to the inner wall of the cabinet 10 in a bent or straight shape by the first permanent magnet 306. The first permanent magnet 306 is fixed to the bottom end of the rubber strip 301. The rubber strip 301 and the elastic metal slide 302 can be attracted to the inner wall of the cabinet 10 by the first permanent magnet 306, allowing for quick one-handed installation and disassembly without pre-drilling or using tools. The positioning component 30 is set on the rubber strip 301. The positioning component 30 is equipped with several elastic clamping plates 318 that can move on the elastic metal slide 302. The elastic clamping plates 318 are used to clamp the wire harness 213 connected to the electrical components. By adopting a sliding and locking elastic clamping plate 318 and rubber strip 301 cooperation structure, the fixed position of the wire harness 213 can be adjusted arbitrarily along the elastic metal slide 302. During maintenance or expansion, the entire wiring harness assembly can be removed simply by pulling the clamping plate outward, significantly shortening construction and maintenance time. The rubber strip 301 and positioning component 30 are arranged against the inner wall of the cabinet 10, occupying far less space than traditional enclosed wire troughs. The wiring harness is arranged in an open manner, allowing for smooth air circulation, which is conducive to heat dissipation and reduces local temperature rise, making it particularly suitable for high power density photovoltaic grid-connected scenarios.

[0024] In one specific embodiment, please refer to Figure 2 and Figure 4The conduit 20 includes a metal telescopic tube 204. One end of the metal telescopic tube 204 is fixedly installed with a first external threaded tube 201, and the other end of the metal telescopic tube 204 is located at the outer end of the cabinet 10. The outer end of the metal telescopic tube 204 is covered with flame-retardant silicone to improve its flame resistance. The metal telescopic tube 204 can automatically adjust its direction according to the bending angle of the wire harness 213, improving the stability of the wire harness 213 installation. A first retaining ring 203 is fixedly installed on the outer wall of the first external threaded tube 201, and a sealing ring is fixedly installed on the side wall of one end of the first retaining ring 203. By passing the first external threaded tube 201 through the inlet hole and threadedly connecting it with a fixing nut 202, and by tightening the fixing nut 202 on the outer wall of the first external threaded tube 201, the sealing ring fits tightly against the outer wall of the cabinet 10, thereby sealing and fixing the first external threaded tube 201 in the inlet hole, and simultaneously fixing the metal telescopic tube 204 to the lower outer side of the cabinet 10.

[0025] Existing wire harness inlets mostly rely on gland heads or rubber sealing rings, which makes it difficult to simultaneously accommodate and secure multiple wires passing through in parallel. In a specific embodiment, please refer to... Figure 4 - Figure 6 One end of the conduit 20 extends out of the outside of the cabinet 10 and is equipped with a fixing structure. The fixing structure is used to separate and fix multiple sets of wire harnesses 213 passing through the conduit 20. Separating and fixing the multiple sets of wire harnesses 213 facilitates maintenance and prevents external accidental contact with the wire harnesses 213, causing them to be pulled off the fixed electrical components. The fixing structure includes a first internal threaded tube 205 fixed to the other end of the metal telescopic tube 204. The end of the first internal threaded tube 205 away from the metal telescopic tube 204 is threadedly connected to a second external threaded tube 206. A second retaining ring 207 is fixedly installed on the outer wall of the second external threaded tube 206. A sealing ring is fixedly installed on the outer end of the second retaining ring 207. The outer wall of the threaded tube 206 is threadedly connected to the inner wall of the first built-in threaded tube 205. The second retaining ring 207 is in close contact with the outer end side wall of the first built-in threaded tube 205 through a sealing ring, sealing the second external threaded tube 206 and the first built-in threaded tube 205. The outer end of the second external threaded tube 206 is closed, and several second built-in threaded tubes 208 are evenly fixedly installed. The second built-in threaded tubes 208 are threadedly connected with a sealing structure. The wire harness 213 can enter the wiring conduit 20 from the second built-in threaded tube 208. The sealing structure is used to fix the wire harness 213 that has entered, and at the same time to block the second external threaded tubes 206 that have not inserted the wire harness 213.

[0026] The sealing structure includes a third external threaded tube 209 threadedly connected to the outer end of the second internal threaded tube 208. Multiple sets of the third external threaded tube 209 are provided to facilitate the parallel insertion of multiple sets of wire harnesses 213. A tapered threaded sleeve 210 is fixedly installed at the outer end of the third external threaded tube 209, and a rubber sleeve is provided at the inner end of the third external threaded tube 209. Several strip-shaped holes are evenly distributed at the outer end of the tapered threaded sleeve 210, and a rubber gasket is fixedly installed on the inner wall of the tapered threaded sleeve 210, which is then fitted onto the outer end of the wire harness 213. The wire harness 213... The outer end of the wire harness 213 is fitted with an adjusting nut 211 that is threadedly connected to the tapered threaded sleeve 210. When the wire harness 213 passes through the second internal threaded tube 208, the outer end of the second internal threaded tube 208 is first threadedly connected to the third external threaded tube 209, and the adjusting nut 211 is fitted onto the outer end of the wire harness 213. After the wire harness 213 is inserted into place, the adjusting nut 211 and the tapered threaded sleeve 210 are threadedly connected. The tapered threaded sleeve 210 retracts inward and fits tightly against the outer wall of the wire harness 213 through the rubber pad, clamping and fixing the wire harness 213.

[0027] In a preferred embodiment, please refer to Figure 5 - Figure 6 The sealing structure includes a sealing block 212 that is threaded to the outer end of the second built-in threaded tube 208. The sealing block 212 is used to thread to the outer end of the second built-in threaded tube 208 through which no wire harness 213 passes, to seal the outer end and prevent foreign objects from entering the cabinet 10 from the second built-in threaded tube 208.

[0028] In one specific embodiment, please refer to Figure 5 - Figure 6 The positioning component 30 includes several sliders 305. The sliders 305 are slidably disposed in the elastic metal slide rail 302. Both the sliders 305 and the elastic metal slide rail 302 have convex cross sections. The sliders 305 can slide freely in the elastic metal slide rail 302. The upper end of the slider 305 slides out of the elastic metal slide rail 302 and is rotatably connected to the base plate 316 through the rotating component. The upper end of the base plate 316 is symmetrically fixedly mounted with elastic clamping plates 318 on the left and right sides. The base plate 316 can rotate with the elastic clamping plates 318 on the upper end of the slider 305, which facilitates the elastic clamping plates 318 to clamp and position the wire harness 213 in different directions.

[0029] In one specific embodiment, please refer to Figure 9The rotating component includes a sleeve 314 fixed to one side of the upper end of the mounting plate 313 and a threaded cylinder 317 fixed to the lower end of the base plate 316. A mounting bolt 315 is inserted into the sleeve 314. The mounting bolt 315 passes through the sleeve 314 and is threadedly connected to the threaded cylinder 317. A limit nut 319 is threadedly connected to the outer wall of the mounting bolt 315. The limit nut 319 is located above the sleeve 314. The distance between the limit nut 319 and the nut of the mounting bolt 315 is greater than the height of the sleeve 314. The mounting bolt 315 can rotate above the slider 305 with the base plate 316, so that the elastic clamping plate 318 can rotate arbitrarily at the upper end of the slider 305.

[0030] In one specific embodiment, please refer to Figure 9 - Figure 10 Each slider 305 has a positioning limiting structure fixedly installed on one side of its upper end. The limiting structure includes an extension plate 307 vertically fixed to one side of the upper end of the slider 305. The extension plate 307 is located above the elastic sheet 303. A rotating rod 309 is rotatably connected to the lower end of the extension plate 307. A support plate 308 is fixedly installed on the lower end of the extension plate 307. The rotating rod 309 is rotatably connected to the lower end of the support plate 308 via a rotating shaft. A second permanent magnet 310 is rotatably connected to one end of the rotating rod 309. The second permanent magnet 310 can be attracted to the elastic sheet 303. At the upper end, when the second permanent magnet 310 is attracted to the upper end of the elastic sheet 303, it fixes the slider 305 and the elastic clamping plate 318. The other end of the rotating rod 309 is provided with an arc-shaped hole 311. The arc-shaped hole 311 is rotatably connected to the push rod 312 through the rotating shaft. The upper end of the push rod 312 slides through the side wall of the extension plate 307 and is connected to the push plate. By pushing the push plate and the push rod 312 downward, the rotating rod 309 can be driven to rotate, and the second permanent magnet 310 and the elastic sheet 303 can be separated, so that the slider 305 can slide with the elastic clamping plate 318.

[0031] The present invention also proposes a photovoltaic grid-connected cabinet, including a wire harness installation structure. The specific structure of the wire harness installation structure is as described in the above embodiments. Since the photovoltaic grid-connected cabinet adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0032] When this device is in operation, the conduit 20 is first fixed in the inlet hole, and a fixing structure is installed on the outer end of the conduit 20. Then, the required electrical components are fixedly installed in the cabinet 10. Next, the required wire harness 213 is passed through the fixing structure and the conduit 20 and enters the cabinet 10. It is fixedly connected to different electrical components, and a rubber strip 301 is magnetically attracted along the path of the wire harness 213. The rubber strip 301 can be bent at will according to the path of the wire harness 213. The positioning component 30 is slidably inserted into the elastic metal slide 302 in the rubber strip 301. The fixed position of the wire harness 213 can be adjusted arbitrarily along the elastic metal slide 302. Finally, the wire harness 213 is clamped in the elastic clamping plate 318. During maintenance or expansion, the entire wire harness assembly can be removed simply by pulling the clamping plate outward, which significantly shortens the construction and maintenance time.
