Description

Technical Field

[0001] This utility model relates to the field of ring main unit accessories, and more specifically, to a wire harness groove for ring main units. Background Technology

[0002] Ring main units (RMS) are key equipment in power distribution systems, widely used in urban power grids, industrial and mining enterprises, and residential communities, undertaking important functions of power distribution, line protection, and control. They contain numerous electrical components such as circuit breakers, disconnectors, instrument transformers, and protection devices, which are connected by complex wiring harnesses. Therefore, efficient, reliable, and neat wiring harness management is crucial for the safe and stable operation of RMS, ease of maintenance, and efficient use of internal space.

[0003] Currently, various types of wire harness channels are commonly used inside ring main units to accommodate and organize wire harnesses, preventing them from becoming messy, tangled, or worn, and facilitating later maintenance. However, existing wire harness channels suffer from poor wire harness fixation and lack of adjustability. They mostly only serve as "left and right limits," failing to apply continuous and uniform clamping force to the wire harnesses and thus unable to effectively suppress their swaying and displacement. Furthermore, most current wire harness channels lack splicing capabilities, resulting in insufficient expandability and flexibility, which require improvement. Utility Model Content

Detailed Implementation

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1 , Figure 2As shown in the figure, a specific embodiment of the present invention discloses a wire harness groove for a ring main unit, including a wire groove 100 and a clamp assembly 200; the clamp assembly 200 is clamped at the groove opening of the wire groove 100, and the clamp assembly can slide along the wire groove and be clamped in the required position after adjustment; the clamp assembly 200 can be used to connect the splice of two wire grooves 100; the clamp assembly can be adjusted and moved down to provide a tight clamping and locking for the wire harness.

[0028] The aforementioned wire harness trough for a ring main unit has a clamp assembly that can slide along the trough and be adjusted to the desired position. The clamp assembly can be moved to the desired position as needed to provide targeted limiting for the wire harness. The clamp assembly can be used to connect the splicing points of two wire harnesses and can be selected and combined according to different length requirements to improve expandability and flexibility of use.

[0029] Furthermore, the clamp assembly can be adjusted and moved downwards to provide a clamping and locking effect on the wire harness, which can provide a clamping force to the wire harness, effectively preventing the wire harness from easily loosening or shaking, and improving the overall stability.

[0030] Furthermore, such as Figure 3 , Figure 4 As shown, the clamp assembly 200 includes a support frame 210, the bottom of which is provided with a slot 220, the shape of which is adapted to the shape of the wire groove 100; clips 230 are fixedly provided at both ends of the bottom sides of the support frame 210; as shown Figure 1 , Figure 2 As shown, the two side walls of the wire trough 100 are provided with a plurality of strip openings 110 evenly spaced along the length direction. The strip openings extend along the vertical direction of the wire trough, and the width of the strip openings 110 is adapted to the width of the card 230. The card bent inward can be inserted into the strip opening to lock the support frame in the required position. This structural design can limit the support frame from moving left and right by bending the card into the strip opening, so as to keep it in the required position. The distance from the strip opening at the end position to the end face of the wire trough is adapted to the distance from the card to the center of the side wall of the support frame. When the ends of the two wire troughs are spliced ​​and aligned, the positions of the two strip openings near the splicing part correspond exactly to the positions of the card. The clamp assembly can be moved to this part to achieve the effect of splicing parts.

[0031] Furthermore, such as Figure 1 As shown, at least one first retaining strip 120 is fixedly provided on the top of the outer walls on both sides of the wire groove 100. The first retaining strip extends to both ends along the length of the wire groove, and the cross-section of the first retaining strip 120 is a serrated structure; as shown Figure 3 , Figure 4As shown, the inner walls on both sides of the bayonet 220 are fixedly provided with first locking teeth 221. The shape of the first locking teeth is adapted to the shape of the first locking strip. The first locking teeth 221 engage with the first locking strip 120, causing the support frame to move downward and be locked. Through the cooperation of the first locking strip and the first locking teeth, the support frame forms a unidirectional downward movement and a restricted reverse movement effect. When the support frame moves down to hold the wire harness, the engagement and locking effect of the first locking strip and the first locking teeth is strengthened under the reaction force of the wire harness, thereby effectively pressing the wire harness and preventing the wire harness from easily loosening or shaking. It should be noted that if it is necessary to move the clamp assembly upward, it can be adjusted by squeezing the two sides of the wire groove or prying up one side of the bayonet.

[0032] Furthermore, such as Figures 4 to 7 As shown, a through hole 211 is provided in the center of the top surface of the support frame 210. The through hole has a rectangular hole structure. Upright plates 240 are fixed on both sides of the top of the through hole 211. The length of the upright plates 240 is greater than the length of the through hole 211. A pressure block 250 is provided at the through hole 211. At least one second locking strip 251 is fixed on the top of the wall of the pressure block 250 near the upright plate. The second locking strip extends to both ends along the length of the pressure block. The cross-section of the second locking strip 251 has a serrated structure. A second locking tooth part 241 is fixed on the wall of the upright plate 240 near the through hole. The shape of the second locking tooth part matches the shape of the second locking strip. The second locking tooth part 241 engages with the second locking strip 251, so that the pressure block moves downward and is locked. The setting of the pressure block can form a second level of pressing and fixing effect. On the one hand, it can further enhance the overall pressing effect. On the other hand, it can be applied to the case where the number of wire harnesses is insufficient, to prevent the support frame from failing to achieve the pressing effect. The downward locking method is also used for easy operation.

[0033] Furthermore, the pressure block is a hollow structure with the upper and lower walls running through it. A support bar is fixed in the middle of the upper end of the pressure block, and the bottom surface of the support bar is arc-shaped. The pressure block adopts this structure, which can reduce the overall weight, reduce material usage and reduce production costs. On the other hand, it can leave a gripping part, especially when it is necessary to lift the pressure block upward to adjust its position, the part of the support bar can be used for operation.

[0034] Furthermore, such as Figures 5 to 7 As shown, the top surface of the support frame 210 is fixedly provided with a first support plate 260 and a second support plate 270 arranged opposite to each other. The upright plate 240 and the through hole 211 are located between the first support plate 260 and the second support plate 270, and there are gaps between the two sides of the upright plate and the first support plate and the second support plate, which does not affect the movement of the upright plate and ensures that the upright plate can provide space for deformation and movement, so that the pressure block can be pressed down and moved.

[0035] Support blocks 261 are fixed at both ends of the wall away from the perforation of the first support plate 260. The top of the support blocks is higher than the top of the first support plate. A pressure cover 280 is rotatably mounted between the tops of the two support blocks 261. The pressure cover can be rotated and swung to the top surface of the first and second support plates to cover the pressure blocks and upright plates below. Since the pressure blocks are also operated by pushing down, the pressure cover can cover the pressure blocks. The support frame can be moved and adjusted by pressing the pressure cover. When the pressure blocks need to be adjusted, the pressure cover can be opened. The adjustment actions do not interfere with each other.

[0036] Furthermore, the top of the support block is provided with a countersunk hole; one end of the pressure cap is fixedly provided with a convex shaft, and a corresponding round hole is provided on the convex shaft; the convex shaft is placed between the two support blocks and is connected by a rotating shaft passing through the countersunk hole and the round hole to achieve a rotating connection; wherein, with the countersunk hole structure, the rotating shaft is a smooth straight bar structure before assembly, and after assembly, by clamping force at both ends, a clamping head that fits the countersunk hole is formed, thereby making the pressure cap firmly rotatably connected to the support frame; of course, including but not limited to the above connection method, long bolts or long pins can also be used as rotating connection components;

[0037] Furthermore, such as Figures 4 to 7 As shown, a pressure plate 281 is fixedly provided on the bottom surface of the end of the pressure cap 280 away from the support block 261; when the pressure cap 280 rotates and swings to press against the top surface of the second support plate 270, the pressure plate 281 abuts against the wall surface of the second support plate 270 away from the first support plate and forms a locking connection to prevent the pressure cap from easily loosening and opening, so as to keep it in a closed and covered state for easy use; wherein, the top edge of the second support plate and the bottom edge of the pressure plate are provided with chamfers, which can facilitate the pressure plate to swing smoothly into place and form the required locking connection to complete the closing of the pressure cap;

[0038] Furthermore, baffles 282 are fixedly provided on both sides of the bottom surface of the pressure cap 280. When the pressure cap 280 rotates and swings to press against the top surface of the second support plate 270, the baffles 282 abut against the top of the outer wall surface of the upright plate 240. The baffles limit the top of the upright plate, making it upright and preventing the upright plate from deviating outward and causing the pressure block to loosen. This strengthens the clamping force on the pressure block and maintains the effective downward pressure of the pressure block. Furthermore, the bottom surface of the baffle is an arc-shaped structure. Since the upright plate may tilt outward and be pushed outward under the pressure block, the arc shape of the bottom of the baffle can play a certain guiding role, making it easier to insert and close the pressure cap.

[0039] This utility model has been described through preferred embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. This utility model is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims of this application are all within the protection scope of this utility model.
