Description

Technical Field

[0001] The present invention relates to a busbar fixing structure based on snap connection. Background Art

[0002] With the emergence of modern engineering facilities and equipment, the power consumption in all walks of life has increased rapidly. Especially with the appearance of numerous high-rise buildings and large factory workshops, traditional cables as transmission conductors can no longer meet the requirements in large-current transmission systems. The parallel use of multiple cables brings many inconveniences to on-site installation and construction connections. As a result, busbar trunking has emerged as a new type of distribution conductor. The original wires and cables have gradually been replaced by busbar trunking due to their small capacity, inconvenient branching, and inconvenient bundle management. Compared with traditional cables, it fully demonstrates its superiority in large-current transmission. At the same time, due to the adoption of new technologies and new processes, the contact resistance and temperature rise at the connection points at both ends of the busbar trunking and the plug-in points of branch lines have been greatly reduced, and high-quality insulating materials have been used in the busbar trunking, thereby improving the safety and reliability of the busbar trunking and making the entire system more perfect. Busbar trunking is widely used in key projects such as the power transmission main line of fire-fighting equipment and the main line of fire emergency equipment, for example, in important projects such as hotels, airports, and subways. Therefore, the product performance of busbar trunking is crucial. Summary of the Invention

[0003] The purpose of the present invention is to solve the above-mentioned deficiencies of the prior art and provide a busbar fixing structure based on snap connection.

[0004] A busbar fixing structure based on snap connection includes a main busbar and a busbar support. The main busbar is in the shape of a rectangular sheet, and several groups of spaced-apart clamping blocks are provided at the bottom of the main busbar. Each clamping block includes two grooves that cooperate with trapezoidal protrusions respectively provided on the left and right sides of the main busbar. The shape of the groove is an isosceles trapezoid, and the positions of the grooves on the left and right sides are one in front of the other and symmetric about the center. The busbar support includes a rectangular block. Flanges are provided on both sides of the top surface of the rectangular block, and long circular holes are provided on the flanges. Several main busbar slots are provided on the top surface of the rectangular block. A clamping groove that matches the shape of the clamping block is provided in the main busbar slot. A sliding groove perpendicular to the direction of the clamping groove is provided at the bottom of the clamping groove. The sliding groove communicates with the clamping groove and the cross-section of the sliding groove and the clamping groove is in an L shape;

[0005] As a further improvement, the trapezoidal protrusion is formed by stamping process.

[0006] As a further improvement, the number of groups of the clamping blocks ≥ 2 groups.

[0007] As a further improvement, the material of the busbar support is PA66 engineering plastic.

[0008] As a further improvement, the number of main busbar slots on the busbar support is 5.

[0009] As a further improvement, the length of the chute ≥ the total length of a set of trapezoidal protrusions in the front and back directions.

[0010] As a further improvement, the cooperation mode between the main busbar and the busbar support is as follows: several main busbars are placed side by side with their heads and tails aligned, and the positions of the clamping blocks on the main busbars are also aligned one by one. The number of main busbars is the same as the number of main busbar slots on the busbar support. One main busbar is provided in each main busbar slot. The clamping block on the main busbar passes through the clamping groove and slides forward to be fixed in the chute communicated with the clamping groove. The clamping grooves and the chutes are connected in sequence from front to back. The last busbar support rotates 180° to be connected with the main busbar to lock the main busbar.

[0011] Beneficial effects:

[0012] The present invention is ingeniously designed. The main busbar and the busbar support are connected through the clamping block and the clamping groove, which is convenient to connect, has a compact structure and high safety. The busbar support is a universal part, which is convenient to process and has good economy. Description of the drawings
