Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a busbar connecting device. Background Art

[0002] During the installation of electrical secondary equipment, the main power supply method for multi-sided cabinets installed side by side is to install a small busbar on the top of the cabinet. The role of the small busbar on the top of the cabinet in the power connection can be said to be the core of safe power-on operation.

[0003] At present, during the installation of the small busbar on the cabinet top, bolts are usually used for fastening, and the connection is exposed to the air. The small busbar exposed to the air usually turns black due to air oxidation and the flow of current at the bare copper connection point, which increases its own resistivity. In the later operation, the small busbar at the connection point heats up or the bolts loosen, causing safety accidents, which often cause significant economic losses. Utility Model Content

[0004] The technical problem to be solved by the utility model is: to provide a busbar connecting device in view of the above-mentioned existing problems.

[0005] The technical solution adopted by the utility model is: a busbar connecting device, characterized in that it comprises:

[0006] Busbar clamp, installed on the top of the equipment cabinet, used to fix the busbar;

[0007] A busbar assembly, comprising a first busbar and a second busbar, wherein the first busbar and the second busbar are both mounted on the busbar clamp;

[0008] The cold shrink tube is used to encapsulate the connection point between the first busbar and the second busbar.

[0009] Through the above technical means, the busbar clamp is used to provide a fixed base for the first busbar and the second busbar, and the connection point between the first busbar and the second busbar is encapsulated with a cold shrink tube. The cold shrink tube is used to protect the connection of the busbars, reducing the direct contact between the busbar connection and the air. The cold shrink tube is easy to stretch and use, which can improve construction efficiency.

[0010] In some embodiments, the busbar clamp has a wire clamp portion and a base portion, and the wire clamp portion and the base portion are solid integrated structures.

[0011] In some embodiments, fixing ears are provided at both ends of the busbar clamp, bolt holes are provided on the fixing ears, and the busbar clamp is fixed to the top of the equipment cabinet by bolts.

[0012] In some embodiments, a spring piece is provided at the end of the first busbar, and the spring piece is used to connect and fix the first busbar and the second busbar.

[0013] In some embodiments, the busbar clamp is made of solid plastic material.

[0014] The beneficial effects of the utility model are:

[0015] 1. Install the first busbar and the second busbar through the busbar clamp on the top of the equipment cabinet. The connection point between the first busbar and the second busbar is encapsulated with a cold shrink tube. The cold shrink tube has good sealing performance. After shrinking, the cold shrink tube can fit tightly to the connection of the busbar, thereby reducing the direct contact between the busbar connection and the air, ensuring the stability of the electrical connection, and reducing the risk of safety accidents caused by the busbar; at the same time, the cold shrink tube has good high temperature resistance and can maintain stable performance in a wider temperature range, thereby extending the service life of the electrical connection point; the installation process of the cold shrink tube does not require special tools, and only needs to stretch the internal cold shrink strip to shrink and fix it, which improves the convenience of construction.

[0026] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the technical solution of the present utility model is further described below in conjunction with specific embodiments.

[0027] Combination Figures 1 to 5 As shown, this embodiment is a busbar connection device, including a busbar clamp 2, a busbar assembly 3 and a cold shrink tube 4. The busbar clamp 2 is installed on the top of the equipment cabinet 1, and the busbar clamp 2 is used to fix the busbar. The busbar assembly 3 includes a first busbar 5 and a second busbar 6. The first busbar 5 and the second busbar 6 are both installed on the busbar clamp 2. The connection point between the first busbar 5 and the second busbar 6 is encapsulated with a cold shrink tube 4.

[0028] In some embodiments, such as Figure 2 As shown, the busbar clamp 2 has a wire clamp portion and a base portion, and the wire clamp portion and the base portion are solid integrated structures. The size and spacing of the wire clamp portion are controlled to facilitate the first busbar 5 and the second busbar 6 to be embedded therein, thereby preventing the first busbar 5 or the second busbar 6 from being misplaced. Fixing ears are provided at both ends of the base portion, and bolt holes 7 are provided on the fixing ears. The busbar clamp 2 is fixed to the top of the equipment cabinet 1 by bolts, thereby preventing the busbar clamp 2 from falling off, and the installation position is reasonably arranged according to the size of the top of the equipment cabinet 1.

[0029] Furthermore, the busbar clamp 2 is made of solid plastic material, which has the properties of anti-oxidation and anti-aging.

[0030] In some embodiments, a spring piece 8 is provided at the end of the first busbar 5, and the spring piece 8 is used to connect and fix the first busbar 5 and the second busbar 6. Specifically, Figure 4 and Figure 5 As shown, when the first busbar 5 and the second busbar 6 at both ends are inserted into the cold shrink tube 4 and assembled, the cold shrink strip inside the cold shrink tube 4 is pulled out to lock and fix, so that the connection point of the first busbar 5 and the second busbar 6 is fixed.

[0031] The cold shrink tube 4 has good sealing performance. After shrinking, the cold shrink tube 4 can fit tightly around the connection point between the first busbar 5 and the second busbar 6, forming a reliable protection to ensure the stability and reliability of the electrical connection. The cold shrink tube 4 is easy to operate. No special tools are required during the installation process of the cold shrink tube 4. It only needs to stretch the internal cold shrink strip to shrink it into place, thereby effectively fixing the connection between the first busbar 5 and the second busbar 6 and improving the convenience of construction. The cold shrink tube 4 also has good high temperature resistance, low temperature resistance and other characteristics, and can maintain stability in a wider temperature range. Therefore, with the help of the cold shrink tube 4, the service life of the connection between the first busbar 5 and the second busbar 6 can be extended, and the construction of the cold shrink tube 4 is also beautiful.

[0032] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
