Description

Technical Field

[0001] The utility model relates to the technical field of new energy energy storage containers, and particularly relates to a quick-insert busbar structure. Background Art

[0002] With the continuous implementation and mass production of energy storage containers with larger capacities, how to obtain a larger energy storage capacity without increasing the size of the existing energy storage containers? Only by increasing the size of the battery cells and improving the energy density of the battery cells. Increasing the size of the battery cells requires continuously squeezing the existing space size of the busbar cabinet and optimizing the layout of the busbar cabinet itself. On the other hand, the number of cluster-level high-voltage boxes increases with the number of clusters, and the number of high-voltage power lines from the high-voltage boxes to the busbar cabinet also increases.

[0003] In the prior art, the fixing method of the high-voltage power line in the busbar cabinet is to crimp a copper nose terminal on the high-voltage cable and then fasten it by locking bolts. This method requires a high-voltage copper nose terminal with a sufficient contact area to reduce the contact resistance between the terminal and the busbar. With the increase in the number of high-voltage busbars, the traditional method requires continuously increasing the volume of the busbar, which will also increase the size of the energy storage busbar cabinet, making it contradictory to the actual design requirement of compressing and optimizing the size of the busbar cabinet. At the same time, it causes great difficulties in on-site actual installation and operation, greatly affecting the production efficiency of energy storage containers. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the utility model provides a quick-insert busbar structure, which not only reduces the structural size of the busbar in the prior art, optimizes the space size of large-capacity energy storage containers, improves the installation efficiency of workers, but also increases the high-voltage busbar connection points of the busbar cabinet and the contact area of the fixed end.

[0005] To achieve the above object, the utility model designs a quick-insert busbar structure, which includes a copper plate main body. A plurality of cylindrical docking sockets are installed on the copper plate main body. A tubular plug is provided on the docking socket to cooperate with it. An L-shaped mounting plate is fixed at the bottom of the copper plate main body, and the L-shaped mounting plate fixes the copper plate main body on the inner wall of the energy storage container box body. Through the design of the cylindrical docking socket and the tubular plug, the contact area between the socket and the plug is increased, and heat generation is reduced.

[0006] Preferably, the docking socket, the tubular plug and the L-shaped mounting plate are all made of copper material.

[0007] Preferably, two limiting convex blocks are symmetrically arranged in the bottom area of the outer wall of the docking socket. Two inverted L-shaped through holes corresponding to the limiting convex blocks are provided at the bottom end of the tubular plug. One side of the inverted L-shaped through hole extends along the axial direction of the tubular plug, and the other side extends along the radial direction of the tubular plug.

[0008] Preferably, a buffer spring is provided inside the tubular plug, and a spring cap is fixed to the top of the buffer spring.

[0009] Preferably, two semi-circular bumps are symmetrically arranged on the outer wall of the tubular plug. The two semi-circular bumps can increase the friction force between the staff and the outer wall of the tubular plug.

[0010] Preferably, the top of the tubular plug is arc-shaped. The arc-shaped design enables the docking socket to be inserted more quickly.

[0011] Preferably, the docking sockets are evenly spaced and cover the entire top surface of the copper plate body.

[0012] Preferably, the L-shaped mounting plate includes a vertical support plate and a bottom plate.

[0013] Preferably, two waist-shaped holes are provided on the support plate, and insulating fixing studs are provided in the waist-shaped holes.

[0014] Preferably, a plurality of fuse fixing stud holes are provided on the bottom plate. The tubular plug is fixed to the fuse through the fuse fixing stud holes.

[0015] Preferably, the copper plate body and the L-shaped mounting plate are of an integrally formed structure. The copper plate body and the L-shaped mounting plate are integrally formed by bending a whole copper plate downward.

[0016] Advantages of the present utility model:

[0017] 1. The present utility model reduces the structural size of the busbar in the prior art, optimizes the space size of the large-capacity energy storage container, greatly increases the contact area of the high-voltage busbar connection points and the fixed ends in the busbar cabinet, improves the installation efficiency of the staff, and thus speeds up the production efficiency of the energy storage container.

[0018] 2. Compared with the prior art in which the terminals are fixed by bolts, the present utility model has more plug-in structure component plug-in points under the same size conditions, which is 2 to 3 times that of the existing busbar cabinet, greatly saving the cost of the material itself.
