Description

Technical Field

[0001] This utility model relates to the technical field of power system distribution cable positioning, and in particular to a cable clamp for an energy metering box. Background Technology

[0002] A cable clamp for an electricity metering box is a mechanical device installed inside an electricity metering box to fix, support, and organize large-section cables (thick conductors) leading out from the circuit breaker terminals.

[0003] In related technologies, existing cable clamps for electricity metering boxes mostly adopt fixed-diameter ring clamps or integrated multi-hole strip structures. However, these structures have poor adaptability in practical applications. One type of clamp can only match a specific wire diameter, requiring multiple spare parts to be prepared for cables of different thicknesses, making management and installation inconvenient. Furthermore, they lack effective support; traditional clamps can only provide radial clamping force and cannot support the weight of the cable, easily leading to loosening of the terminals. They also lack flexibility, have a fixed installation direction, and are difficult to handle complex wiring requirements within the box. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a cable clamp for an electricity metering box. It adopts a multi-functional integrated design, supports 360-degree rotation and locking through the adjustment components, and can flexibly adjust the wiring direction. It utilizes an openable movable plate and a liftable limit frame to steplessly adjust the effective diameter of the clamp and provides key support for the cable, effectively improving the flexibility and safety of wiring.

[0006] To achieve the above objectives, this utility model proposes a cable clamp for an electricity metering box, comprising a support frame, multiple adjusting components, and multiple clamp locking mechanisms. The multiple adjusting components are rotatably connected to the support frame and respectively drive the multiple clamp locking mechanisms to rotate and adjust. Each clamp locking mechanism includes two columns, a fastening component, and a supporting component. The fastening component is mounted on the adjusting component via the two columns, and the supporting component is movably connected to the fastening component.

[0007] In addition, the cable clamp for the power metering box proposed above according to this utility model may also have the following additional technical features: Specifically, the fastening assembly includes a fixed plate, two movable plates, two connecting plates, and a second stud. The fixed plate is disposed on the two columns, the two movable plates are rotatably connected to the fixed plate, the two connecting plates are disposed on the two movable plates, and the second stud is detachably disposed on the two connecting plates and passes through the two connecting plates.

[0008] Specifically, the support assembly includes a third stud and a limiting bracket, wherein the third stud is movably connected to the fixed plate and threadedly connected to the fixed plate, and is disposed through the adjustment assembly, and the limiting bracket is disposed on the third stud.

[0009] Specifically, the adjustment assembly includes a support plate and a first stud, wherein the support plate is rotatably connected to the support frame, the first stud is disposed on the support frame and threadedly connected to the support frame, and contacts the support plate.

[0010] Specifically, the support frame is provided with positioning plates on both sides, and positioning holes are opened in the positioning plates.

[0011] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: The cable clamp of the power metering box of this utility model adopts a multi-functional integrated design. It supports 360-degree rotation and locking through the adjustment component, which can flexibly adjust the wiring direction and perfectly adapt to the complex spatial structure inside the box. At the same time, it combines an openable movable plate and a liftable limit frame to realize stepless adjustment of the effective diameter of the clamp, which significantly widens the range of wire diameter adaptation. The active lifting of the limit frame provides key support for the cable, effectively eliminating the stress on the terminal block. It effectively improves the flexibility and safety of wiring, while realizing efficient and reliable cable management.

[0015] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0016] The following description, in conjunction with the accompanying drawings, describes the cable clamp for the power metering box of this utility model.

[0017] like Figures 1-5 As shown, the cable clamp of the power metering box in this embodiment of the present invention may include a support frame 1, multiple adjustment components 2 and multiple clamp locking mechanisms 3.

[0018] Among them, multiple adjustment components 2 are rotatably connected to the support frame 1, and each drives multiple clamping locking mechanisms 3 to rotate and adjust.

[0019] Positioning plates 11 are provided on both sides of the support frame 1, and positioning holes 111 are opened in the positioning plates 11.

[0020] It should be noted that the support frame 1 described in this embodiment is a long rectangular frame, which is fixed in the box by bolts inserted through the positioning holes 111 on both sides. It can stably support multiple adjustment components 2 and multiple clamp locking mechanisms 3, and use multiple adjustment components 2 to adjust the rotation direction of multiple clamp locking mechanisms 3 respectively, so as to flexibly adjust the wiring direction.

[0021] The clamp locking mechanism 3 includes two columns 31, a fastening component 32, and a support component 33.

[0022] The fastening component 32 is mounted on the adjusting component 2 via two uprights 31, and the supporting component 33 is movably connected to the fastening component 32.

[0023] It should be noted that the two columns 31 described in this embodiment are arranged in parallel, stably supporting the fastening component 32 above the support frame 1, while improving the stability of the support component 33. By adjusting the movement of the support component 33, the diameter of the fastening component 32 can be infinitely adjusted.

[0024] Specifically, in practical applications, relevant personnel fix this device inside the electricity metering box, close to the wiring terminals of the circuit breaker and AC contactor. Depending on the installation location, it is suitable for horizontal positioning of three thick wires or for supporting positioning of thin wires bundled together over a long distance.

[0025] In the initial state, the adjusting component 2 is loose, and each clamping locking mechanism 3 is horizontally distributed. At the same time, the two movable plates 322 are far apart from each other, the second stud 324 is not connected, and the limiting frame 332 is close to the bottom fixed plate 321.

[0026] When multiple thick wires are positioned horizontally, the orientation of the clamp locking mechanism 3 can be changed by rotating the support plate 21, and the first stud 22 can be tightened to achieve the angular positioning of the support plate 21. The thick wires are placed on multiple support frames respectively, and the two movable plates 322 on both sides are fastened to make the two connecting plates 323 fit together. The second stud 324 is locked to fix the wires. At the same time, the third stud 331 is rotated in the forward direction. The third stud 331 is threadedly connected to the fixed plate 321, which pushes the limit frame 332 to rise. This is suitable for clamping and positioning wires of different thicknesses and realizes stepless adjustment of the clamp diameter.

[0027] When supporting the bundled thin wires, rotate the support frame so that the openings of the multiple clamping locking mechanisms 3 are arranged along the length of the support frame 1. Place the long wires on the multiple limiting frames 332 in sequence, and then fasten the two movable plates 322 in sequence so that the two connecting plates 323 are in contact. Lock the second stud 324 to fix the long wires. According to the diameter of the long wires, rotate the third stud 331 to adjust the height of the limiting frame 332 to clamp and position the bundled thin wires.

[0028] In one embodiment of this utility model, such as Figures 3-5 As shown, the fastening assembly 32 includes a fixed plate 321, two movable plates 322, two connecting plates 323, and a second stud 324.

[0029] The fixed plate 321 is mounted on the two columns 31, the two movable plates 322 are rotatably connected to the fixed plate 321, the two connecting plates 323 are mounted on the two movable plates 322, and the second stud 324 is detachably mounted on the two connecting plates 323 and passes through the two connecting plates 323.

[0030] It should be noted that the fixed plate 321 described in this embodiment is set in an arc shape, with both ends pivotally connected to one end of the two movable plates 322 respectively. When the two connecting plates 323 are attached, the two movable plates 322 and the fixed plate 321 form a ring structure, which is combined to form a clamp. The clamp structure is locked by passing through the two connecting plates 323 through the second stud 324.

[0031] In one embodiment of this utility model, such as Figures 3-5 As shown, the support assembly 33 includes a third stud 331 and a limiting bracket 332.

[0032] The third stud 331 is movably connected to the fixed plate 321 and threadedly connected to the fixed plate 321, and passes through the adjustment assembly 2. The limit bracket 332 is set on the third stud 331.

[0033] It should be noted that the two ends of the third stud 331 proposed in the above embodiment pass through the support plate 21 and the fixing plate 321 respectively, and are threadedly connected to the fixing plate 321. The height of the limiting frame 332 is adjusted by the threaded connection. The limiting frame 332 adopts a V-shaped setting, which is suitable for supporting wires of different diameters.

[0034] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the adjustment component 2 includes a support plate 21 and a first stud 22.

[0035] The support plate 21 is rotatably connected to the support frame 1, and the first stud 22 is disposed on the support frame 1 and threadedly connected to the support frame 1, and in contact with the support plate 21.

[0036] It should be noted that the outer circumference of the support plate 21 described in this embodiment is recessed and is rotatably connected to the support frame 1 through a slot. At the same time, the first stud 22 passes through the side of the support frame 1 and is supported on the side wall of the support plate 21 through the threaded connection between the first stud 22 and the support frame 1, thereby achieving the angular positioning of the support plate 21.

[0037] In summary, the cable clamp of the power metering box in this embodiment of the utility model adopts a multi-functional integrated design. It supports 360-degree rotation and locking through the adjustment component, which can flexibly adjust the wiring direction. It uses an openable movable plate and a liftable limit frame to steplessly adjust the effective diameter of the clamp and provides key support for the cable, effectively improving the flexibility and safety of wiring.
