Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical equipment technology, and in particular to a copper busbar clamp for a distribution cabinet. Background Technology
[0002] Copper busbar clamps are key components used to fix and separate copper busbars within a distribution cabinet. Their main function is to ensure the orderly arrangement and stable installation of copper busbars within the cabinet, while preventing short circuits caused by contact between adjacent busbars, thus ensuring the safe operation of the distribution cabinet. Currently, most busbar clamps are of a single, integrated structure. This type of structure has a fixed slot size, making it unable to flexibly adapt to copper busbars of different widths, resulting in poor versatility. Furthermore, the isolation design of this integrated structure is relatively simple, and dust and other conductive media can easily accumulate in the gaps between adjacent copper busbars. Over time, this accumulation of conductive media may lead to short circuits, failing to meet the requirements for safe operation of the distribution cabinet.
[0003] Therefore, those skilled in the art have provided a copper busbar clamp for a distribution cabinet to solve the problems mentioned in the background art. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a copper busbar clamp for power distribution cabinets.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A copper busbar clamp for a power distribution cabinet includes a left clamp and a right clamp. The left and right clamps have the same structure and are symmetrically arranged. Multiple semi-accommodating slots are symmetrically opened on adjacent sides of the left and right clamps. The semi-accommodating slots on the left and right clamps can be combined into a complete copper busbar accommodating slot. A positioning post is provided between the left and right clamps. Screw through holes are opened on the sides of both the left and right clamps.
[0007] Preferably, the top ends of the left and right clamping blocks are integrally formed with isolation ribs between the two adjacent half-accommodating grooves.
[0008] Preferably, the left clamping block, the right clamping block, and the positioning post are all made of ceramic material.
[0009] Preferably, at least two positioning posts are provided, and the left clamping block, the right clamping block and the positioning posts are all made of any one of the following materials: ceramic material, bakelite board, SMC (sheet molding compound) and DMC (bulk molding compound).
[0010] Preferably, the screw through hole is connected to the positioning hole, and the positioning post has a screw clearance hole in the middle along the axial direction.
[0011] Preferably, both the left and right clamping blocks have weight-reducing cavities on their outer surfaces.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] The left and right clamping blocks are symmetrically arranged and merged into a complete copper busbar receiving slot through a semi-accommodating groove.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Reference Figure 1-4A copper busbar clamp for a power distribution cabinet includes a left clamp 1 and a right clamp 2. The left clamp 1 and the right clamp 2 have the same structure and are symmetrically arranged. Multiple semi-accommodating slots 3 are symmetrically opened on the adjacent sides of the left clamp 1 and the right clamp 2. The semi-accommodating slots 3 on the left clamp 1 and the right clamp 2 can be combined into a complete copper busbar accommodating slot. A positioning post 4 is provided between the left clamp 1 and the right clamp 2. A screw through hole 7 is opened on the side of both the left clamp 1 and the right clamp 2.
[0022] By adopting the above technical solution, the symmetrical structure of the left clamping block 1 and the right clamping block 2 and the design of the semi-accommodating groove 3 enable the two to form a complete and precise copper busbar accommodating groove after they are attached. This not only ensures the positioning accuracy of the copper busbar during installation and avoids copper busbar offset, but also allows multiple copper busbars to be installed at the same time through multiple sets of semi-accommodating grooves 3, meeting the needs of dense wiring in the distribution cabinet and improving space utilization. At the same time, the positioning post 4 between the left clamping block 1 and the right clamping block 2 can help maintain their relative positions and ensure that the semi-accommodating groove 3 is precisely aligned.
[0023] The tops of the left clamping block 1 and the right clamping block 2 are integrally formed with isolation ribs 5 between the two adjacent semi-accommodating grooves 3.
[0024] Using the above technical solution, the isolation ribs 5 at the top of the left clamping block 1 and the right clamping block 2 are located between two adjacent half-accommodating grooves 3, which can physically separate the adjacent copper busbars in the accommodating grooves, effectively preventing dust from accumulating between the adjacent copper busbars and avoiding short circuits of the copper busbars caused by the accumulation of conductive media such as dust.
[0025] The left clamping block 1, the right clamping block 2, and the positioning post 4 are all made of any one of the following materials: ceramic material, bakelite board, SMC (sheet molding compound), and DMC (bulk molding compound).
[0026] Using the above technical solutions, the busbar clamp is made of insulating, flame-retardant, and high-temperature resistant materials such as ceramic materials, bakelite boards, SMC (sheet molding compound) and DMC (bulk molding compound). It can adapt to the complex temperature and environmental changes inside the distribution cabinet, extend the service life of the busbar clamp, and its rigidity also ensures the stability of the overall structure.
[0027] At least two positioning posts 4 are provided, and positioning holes 6 are provided on the adjacent sides of the left clamping block 1 and the right clamping block 2 for the end of the positioning post 4 to be inserted.
[0028] By adopting the above technical solution, at least two positioning posts 4 are inserted into the positioning holes 6 of the left clamp 1 and the right clamp 2, which can accurately limit the relative position of the left clamp 1 and the right clamp 2, ensuring that the two always remain parallel and aligned, avoiding the clamps from tilting due to installation or external force, thereby ensuring the accuracy of the groove after the semi-accommodating groove 3 is merged, providing a stable installation foundation for the copper busbar, reducing copper busbar wear. At the same time, the length of the positioning post 4 can be changed according to the width of the copper busbar to adapt to the installation requirements of copper busbars of different specifications and improve the versatility of the busbar clamp.
[0029] The screw through hole 7 is connected to the positioning hole 6, and the positioning post 4 has a screw clearance hole 8 in the middle along the axial direction.
[0030] Using the above technical solution, the screw through hole 7 is connected to the positioning hole 6, and the screw clearance hole 8 in the middle of the positioning post 4 cooperates with both, so that the screw can pass through the screw through hole 7 of the left clamping block 1, the screw clearance hole 8 of the positioning post 4, and the screw through hole 7 of the right clamping block 2 in sequence. In actual installation, the right clamping block 2 can be abutted against the side of a component inside the distribution cabinet, and the screw can be screwed into the component after passing through the above-mentioned hole. While the left clamping block 1 and the right clamping block 2 are firmly fixed, the installation and positioning of the busbar clamp and the components inside the distribution cabinet are completed simultaneously, simplifying the assembly process and improving the installation efficiency.
[0031] The outer surfaces of both the left clamping block 1 and the right clamping block 2 are provided with weight-reducing cavities 9.
[0032] By adopting the above technical solution, the weight reduction cavity 9 on the outer side of the left clamp 1 and the right clamp 2 significantly reduces the overall weight of the busbar clamp while ensuring the structural strength of the clamp.
[0033] Working principle:
[0034] During installation, select a positioning post 4 of the corresponding length according to the width of the copper busbar to be installed, and insert its two ends into the positioning holes 6 of the left clamp 1 and the right clamp 2 respectively, so that the left and right clamps are parallel and the spacing is adapted to the width of the copper busbar; then place the bottom end of the copper busbar into the semi-accommodating groove 3 of the left clamp 1 and the right clamp 2 respectively. At this time, the adjacent copper busbars are separated by the isolation ribs 5 at the top of the left and right clamps to avoid dust accumulation and short circuit; finally, place the right clamp 2 against the side of the preset component in the distribution cabinet, and pass the screw through the screw through hole 7 of the left clamp 1, the screw clearance hole 8 of the positioning post 4 and the screw through hole 7 of the right clamp 2 in sequence, and screw it into the distribution cabinet component, thereby simultaneously fixing the left and right clamps and installing the busbar clamps and the distribution cabinet.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
