Description

Technical Field

[0001] The utility model relates to the technical field of power distribution control equipment, in particular to a wiring harness fixing structure for a power distribution cabinet. Background Art

[0002] The power distribution cabinet distributes the electric energy of a circuit of the upper-level power distribution equipment to the load. This level of equipment should provide protection, monitoring and control for the load. The power distribution cabinet is a device for concentrating, switching and distributing electric energy. The power distribution cabinet is generally composed of a cabinet body and multiple electrical components. The power distribution cabinet is generally installed in power stations, substations and places with large power consumption. The multiple electrical components inside the power distribution cabinet are connected by wire harnesses. In the same power distribution cabinet, the wire harnesses are complicated. If the wire harnesses cannot be effectively organized, it is easy for the lines to be entangled with each other, and even the line short circuit is easy to occur.

[0003] Therefore, a wire harness structure is usually provided in the power distribution cabinet, and the wire harness in the power distribution cabinet is arranged by the wire harness structure to prevent the wire harness from being entangled with each other. For example, Chinese patent application number CN202320139185.9 discloses a power distribution cabinet wire harness fixing device, which includes a magnetic base and a circular buckle; the magnetic base can be magnetically fixed to the inner wall of the distribution box; the circular buckle forms a cavity for elastically clamping the wire, and the circular buckle is connected to the magnetic base. By adopting the above technical solution, the magnetic base is magnetically fixed to the inner wall of the distribution box, and the wires are elastically clamped to the circular buckle, so that the wires in the distribution box are arranged in order. During maintenance, the staff can quickly find the corresponding wires, thereby improving the work efficiency of repairing the distribution cabinet.

[0004] However, in the above-mentioned patent, since different wire harnesses have different diameters, and the inner diameter of the circular buckle is fixed and cannot be adjusted, it can only be used to fix wire harnesses of a single diameter. When the wire harness diameter is larger, it is difficult to insert it into the inside of the circular buckle, and when the wire harness diameter is smaller, the circular buckle cannot have a good limiting and fixing effect on the wire harness, resulting in a small scope of application and certain limitations. Its practicality needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] Combine the following Figures 1 to 7 , describing an embodiment of the utility model.

[0030] For easier understanding, see Figure 1 and Figure 2 The present embodiment discloses a wiring harness fixing structure for a power distribution cabinet, which is arranged in a power distribution cabinet body 1 and includes a fixing rod 2 and a clamping block 5; the fixing rod 2 is horizontally installed between the two side walls of the power distribution cabinet body 1 through a supporting block 3, and forms a set spacing with the rear side wall of the power distribution cabinet body 1; there are multiple clamping blocks 5, and the rear sides of the multiple clamping blocks 5 are respectively clamped on the fixing rod 2 through fixing blocks 4, and a clamping opening 6 is opened on the clamping block 5, and L-shaped notches 7 are respectively opened on the two side walls of the clamping opening 6, and an elastic extrusion piece that can move back and forth relative to the notch 7 is arranged on the notch 7, and a detachable extrusion plate 14 is connected between the two elastic extrusion pieces, which is suitable for moving inward under the action of the two elastic extrusion pieces to squeeze and fix the wiring harness 21 clamped in the clamping opening 6.

[0031] In this embodiment, through the action of the clamping mouth 6, the elastic extrusion piece and the extrusion plate 14, the clamping mouth 6 can make the wire harness 21 directly clamped into it from the outside, which is convenient to use. The wire harness 21 can be clamped in the clamping mouth 6 from the outside by installing the extrusion plate 14 between the two groups of elastic extrusion pieces. Since the elastic extrusion piece has a certain elasticity, the distance between the extrusion plate 14 and the rear side wall of the clamping mouth 6 can be adjusted. When the diameter of the wire harness 21 is large, the extrusion plate 14 can be squeezed outward. When the diameter of the wire harness 21 is small, the elastic extrusion piece can push the extrusion plate 14 inward against the wire harness 21 for limiting and fixing. Therefore, it can be applicable to wire harnesses 21 of different diameters, with strong flexibility and high practicality.

[0032] In this embodiment, L-shaped support openings are provided on the opposite surfaces of the two support blocks 3. The two support blocks 3 are first fixed on the two side walls of the distribution cabinet body 1 respectively, and there is a certain distance between them and the rear side wall of the distribution cabinet body 1. Then, the two sides of the fixing rod 2 are directly placed on the support opening from top to bottom for support and fixation. In order to prevent the fixing rod 2 from shaking left and right, the two side walls of the fixing rod 2 are in contact with the inner wall of the support opening, so that it is convenient to be tightly clamped on the two support openings. The clamping opening 6 is provided on the front side of the clamping block 5, so that the wiring harness 21 is directly clamped from the outside to the inside. After the wiring harness 21 is clamped into the clamping opening 6, the elastic extrusion piece is pulled outward away from the wiring harness 21. Then, the extrusion plate 14 is clamped between the two elastic extrusion pieces and the external force on the elastic extrusion piece is released. The extrusion plate 14 will be pushed in the direction of the wiring harness 21 to extrude and fix the wiring harness 21.

[0033] In an alternative embodiment, see Figure 3 and Figure 7 The elastic extrusion member includes a movable rod 11, a movable plate 8 and a spring 10. The movable rod 11 is horizontally penetrated on the two side walls of the clamping mouth 6 and is movably connected with the two side walls of the clamping mouth 6. The movable plate 8 is vertically connected to one end of the movable rod 11 extending into the notch 7. The spring 10 is sleeved on the movable rod 11, one end of which abuts against the movable plate 8, and the other end abuts against the inner wall of the notch 7. The movable plate 8 can be moved forward and backward by the action of the movable rod 11, thereby driving the extrusion plate 14 connected to the movable plate 8 to move back and forth, which is convenient for adjusting the distance between the extrusion plate 14 and the rear side wall of the clamping mouth 6, that is, it can be suitable for wire harnesses 21 of different sizes. After the movable rod 11 drives the movable plate 8 to move outward to a suitable position, the wire harness 21 is clamped therein, and the extrusion plate 14 is placed between the two movable plates 8. Then, after the external force on the movable rod 11 is released, the movable plate 8 and the extrusion plate 14 are pushed toward the direction of the wire harness 21 by the resetting action of the spring 10, so that the extrusion plate 14 is tightly against the wire harness 21.

[0034] In an optional embodiment, there are two movable rods 11, and the two movable rods 11 are respectively arranged on the two side walls of the clamping mouth 6 from top to bottom. A support rod 12 is vertically connected between the outer ends of the two movable rods 11. The support rod 12 facilitates the two movable rods 11 to be pulled outward at the same time. The two movable rods 11 can improve the stability of the movement of the movable plate 8 and are not prone to shaking.

[0035] In an alternative embodiment, see Figure 6 A movable ring 18 is sleeved on the movable rod 11 on one side, and a push-pull rod 19 is connected to the movable ring 18. A semicircular fastening opening 20 that is compatible with the movable rod 11 on the other side is recessed at the bottom of one end of the push-pull rod 19 away from the movable ring 18, which is suitable for the push-pull rod 19 to be clamped on the movable rod 11 on the other side so as to push the two movable rods 11 back and forth at the same time. Under the action of the movable ring 18, the push-pull rod 19 can rotate freely relative to the movable rod 11. Therefore, when the push-pull rod 19 rotates to the top of the other movable rod 11, it can be buckled on the other movable rod 11 through the action of the fastening mouth 20. In this way, the two movable rods 11 can be connected together under the action of the push-pull rod 19. When the wiring harness 21 is inserted, the fastening mouth 20 of the push-pull rod 19 is first separated from the movable rod 11 to avoid the push-pull rod 19 being horizontally intercepted at the fastening mouth 6, which causes the wiring harness 21 to be unable to be inserted into the fastening mouth 6 from the outside. After the wiring harness 21 is inserted, the fastening mouth 20 of the push-pull rod 19 is buckled on the movable rod 11, and the push-pull rod 19 is pulled outward to simultaneously pull the two movable rods 11 on both sides of the fastening mouth 6 outward. Compared with the above-mentioned embodiment in which two external force points are applied to the support rods 12 on both sides, this embodiment only applies one external force to the push-pull rod 19 to simultaneously pull the movable rods 11 on both sides, which is more convenient to use.

[0036] In an optional embodiment, the width of the movable plate 8 is the same as the width of the bottom end of the notch 7, a straight-line groove 13 is provided on the inner wall of the notch 7, and a slider adapted to the groove 13 is connected to the side of the movable plate 8 close to the groove 13. The stability of the movable plate 8 when moving in the notch 7 can be improved by the action of the groove 13 and the slider, and the movable plate 8 is not prone to shaking when the movable rod 11 pulls the movable plate 8 outward or the movable plate 8 is pushed inward under the action of the spring 10. Furthermore, the grooves 13 can be provided on the side walls and bottom walls of the notch 7, respectively, and sliders are connected to the side and bottom surfaces of the movable plate 8, thereby limiting the movable plate 8 from both sides, and achieving higher stability.

[0037] In an optional embodiment, the extrusion plate 14 is detachably connected to the end face of the movable plate 8 away from the movable rod 11 through a connecting piece, and the connecting piece includes a slide rail 15 and a slide bar 9, the slide rail 15 is vertically opened on the end face of the extrusion plate 14 that is attached to the movable plate 8, and the slide bar 9 is vertically connected to the end face of the movable plate 8 that is attached to the extrusion plate 14 corresponding to the slide rail 15, and the slide bar 9 is suitable for cooperating with the slide rail 15 to fix the extrusion plate 14 on the movable plate 8. After placing the wiring harness 21 into the clamping mouth 6, pull the movable rods 11 on both sides outward to drive the movable plates 8 on both sides to move outward. After there is a certain distance between the wiring harness 21, align the slide rails 15 on the extrusion plate 14 with the slide bars 9 on the two movable plates 8, and then insert the extrusion plate 14 downward onto the slide bar 9. After insertion, release the external force on the movable rod 11, and under the action of the spring 10, the movable plate 8 and the extrusion plate 14 can be pushed forward so that the extrusion plate 14 abuts against the wiring harness 21. When the wiring harness 21 needs to be taken out, pull the movable rod 11 outward. When there is a certain distance between the extrusion plate 14 and the wiring harness 21, lift the extrusion plate 14 upward to separate from the two movable plates 8.

[0038] Preferably, see Figure 4 A lifting block 16 is connected to the outer end surface of the extrusion plate 14, and a groove is formed on the bottom end surface of the lifting block 16. When the extrusion plate 14 needs to be taken out from the two movable plates 8, the hand is inserted into the groove and the extrusion plate 14 can be lifted up by pulling upward. When the extrusion plate 14 needs to be inserted downward on the two movable plates 8, the hand is placed on the lifting block 16, and the slide rail 15 and the slide bar 9 are aligned with each other, and then the lifting block 16 is pressed downward to clamp the extrusion plate 14 on the two movable plates 8, so that the extrusion plate 14 can be pushed in and pulled out.

[0039] In an alternative embodiment, see Figure 5 A plurality of clamping strips 17 are vertically arranged at intervals on the end surface of the extrusion plate 14 close to the wire harness 21. The clamping strips 17 are serrated. The wire harness 21 is tightly clamped by the serrated clamping strips 17, and is not easy to loosen when pulled.

[0040] In other embodiments, a rubber pad may also be connected to the end face of the extrusion plate 14 close to the wiring harness 21. Compared with the clamping strip 17 in the above-mentioned embodiment, the rubber pad has a larger effective surface, that is, a larger contact area with the wiring harness 21, which can further improve stability.

[0041] In an optional embodiment, the fixing rod 2 is arranged in a square shape, and the side of the support block 3 close to the distribution cabinet body 1 is fixedly connected to the side wall of the distribution cabinet body 1 by screws, and the side of the support block 3 away from the distribution cabinet body 1 is provided with an L-shaped support opening, and the two ends of the fixing rod 2 are respectively clamped to the support opening from top to bottom.

[0042] Specifically, when the fixing rod 2 is arranged in a square shape, the fixing block 4 is not easy to slip when it is stuck on it. Similarly, a square groove adapted to the fixing rod 2 is provided at the bottom end of the fixing block 4. In this way, when the fixing block 4 is stuck on the fixing rod 2, it is not easy to rotate up and down, thereby making the clamping block 5 tightly stuck on the fixing rod 2. An L-shaped supporting opening is provided on the side of the supporting block 3 close to the fixing rod 2. The function of the two supporting openings is to facilitate supporting the fixing rod 2. The fixing rod 2 can be directly stuck to the two supporting openings in a horizontal state from top to bottom. The distance between the inner side walls of the two supporting openings is slightly larger than the width of the fixing rod 2, so as to avoid the gap between the fixing rod 2 and the inner wall of the supporting opening being too large when the fixing rod 2 is stuck on the two supporting openings, which may easily cause the fixing rod 2 to shake left and right.

[0043] Preferably, a first magnetic adsorption block is provided on the bottom wall of the support opening, and a second magnetic adsorption block is provided on the bottom end surface of the fixing rod 2 in contact with the support opening corresponding to the first magnetic adsorption block, which is suitable for attracting each other with the first magnetic adsorption block to adsorb and fasten the fixing rod 2 to the two support openings. Through the action of the two magnetic adsorption blocks, when the fixing rod 2 is placed on the support opening, the fixing rod 2 can be tightly adsorbed on the support opening, so that the fixing rod 2 is not easy to move left and right or up and down. When the fixing rod 2 needs to be taken out, the fixing rod 2 can be directly lifted up. The action of the magnetic adsorption blocks facilitates the fixing rod 2 to be adsorbed, fixed and taken out.

[0044] Although the present invention has been described using the above preferred embodiments, it is not intended to limit the scope of protection of the present invention. Any person skilled in the art may make various changes and modifications to the above embodiments without departing from the spirit and scope of the present invention, and the changes and modifications still fall within the scope of protection of the present invention.
