Description

Technical Field

[0001] This invention relates to the field of energy storage connector technology, and in particular to a multi-directional outgoing power energy storage connector. Background Technology

[0002] With the rapid development of the national new energy strategy, the issue of balancing power generation and consumption has become increasingly prominent, leading to a growing demand for energy storage systems. Energy storage systems typically consist of several energy storage units connected to each other via connectors. Currently used energy storage connectors need to meet the technical requirements for high power and high current applications. The market currently favors expensive copper pillar structures or bulky copper busbar structures, which cannot meet the miniaturization requirements for high power and high current applications. Summary of the Invention

[0003] This invention proposes a multi-directional outgoing power storage connector, which solves the problem that high-power, high-current copper pillars in the prior art cannot meet the requirements for miniaturization.

[0004] The technical solution of this invention is implemented as follows: A multi-directional outgoing power storage connector includes an upper cover and a base assembly. The base assembly includes an upper cover connecting plate and a copper busbar fixing sleeve. The upper cover connecting plate is snapped into the upper cover, and the copper busbar fixing sleeve is integrally connected to the bottom center of the upper cover connecting plate, with a copper busbar embedded within the fixing sleeve. The copper busbar includes an integrally connected copper busbar body and a head limiting ring. The copper busbar body extends downwards from the copper busbar fixing sleeve. The top of the head limiting ring has a through hole I, and a locking nut I corresponding to the through hole I is provided inside the head limiting ring. A locking bolt is connected to the locking nut I, and tightening the locking bolt can fix the end of the conductor, facilitating the flow of large current. Furthermore, the copper busbar is simple to manufacture, facilitating its miniaturization.

[0005] A nut seat with a U-shaped structure is fitted inside the head limiting ring, and the locking nut I is set inside the U-shaped structure. The nut seat and the inner wall of the head limiting ring cooperate to limit the locking nut I, which facilitates the installation and use of the locking bolt during wiring.

[0006] The lower part of the copper busbar fixing sleeve is integrally connected with a nut mounting groove, which is located on one side of the copper busbar body. A locking nut II is provided within the nut mounting groove. A through hole II is provided on the copper busbar body, and the locking nut II corresponds to the through hole II. The copper busbar body is also connected to the conductor via bolts and the locking nut II, enabling the copper busbar to operate under high current conditions.

[0007] The copper busbar fixing sleeve is elastically connected with a hook, and the copper busbar body is provided with a limiting hole, which is engaged with the hook. After the copper busbar is installed into the copper busbar fixing sleeve, the hook limits the copper busbar and prevents the copper busbar from detaching from the top of the copper busbar fixing sleeve.

[0008] The upper cover connecting plate has a square structure, with fixing holes at the four corners, and fixing bolts passing through the fixing holes. The upper cover connecting plate is installed onto the box body using fixing bolts.

[0009] The upper surface of the upper cover connecting plate is provided with a positioning plate, which mates with the inner wall of the upper cover; the positioning plate is located at the four corners of the square structure. The positioning plate facilitates the alignment of the relative positions of the upper cover and the base assembly, making it convenient for the installation of the upper cover.

[0010] Each of the four sides of the square structure has a hanging platform at its center, and the top cover has two oppositely arranged hanging rings connected to the hanging platforms. The hanging rings connect to the hanging platforms at different positions, enabling the top cover and the base assembly to be connected in different directions.

[0011] The top cover has a cross-shaped structure, and one end of the cross-shaped structure is provided with a conductive output groove. The conductive output groove limits the direction of the wires, enhancing the applicability of the energy storage connector.

[0012] The beneficial effects of this invention are as follows: the copper busbar is connected and fixed to the wires by bolts and nuts, which meets the high power requirements of the energy storage connector. At the same time, the copper busbar is made by bending and stamping, which facilitates the miniaturization of the energy storage connector and effectively reduces the cost of the copper busbar. The top cover of the energy storage connector can be connected to different positions of the base assembly to adjust the wire output direction, so that the energy storage connector can be used in application scenarios with different output directions.

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1, as Figure 1 , Figure 2 As shown, a multi-directional outgoing power storage connector includes an upper cover 10 and a base assembly 20. The base assembly 20 includes an upper cover connecting plate and a copper busbar fixing sleeve. The upper cover connecting plate is snapped into the upper cover 10, and the copper busbar fixing sleeve is integrally connected to the bottom center of the upper cover connecting plate. A copper busbar 3 is embedded in the copper busbar fixing sleeve. The copper busbar fixing sleeve fixes the copper busbar 3, ensuring stable installation. The copper busbar 3 includes an integrally connected copper busbar body and a head limiting ring 32. The copper busbar body extends downwards from the copper busbar fixing sleeve. The top of the head limiting ring 32 has a through hole I, and a locking nut I4 corresponding to the through hole I is provided inside the head limiting ring 32. In this embodiment, the copper busbar 3 is manufactured by stamping, cutting, and then folding, which facilitates mass production of the copper busbar 3 and reduces production costs. At the same time, the head limiting ring 32 of the copper busbar 3 is connected to the wire through the locking nut I4 and bolts, ensuring that the copper busbar 3 can meet the high power and high current requirements of the connector.

[0023] Furthermore, such as Figure 5 , Figure 6 As shown, a nut seat 41 is fitted inside the head limiting ring 32. The nut seat 41 has a U-shaped structure, and the locking nut I4 is disposed within the U-shaped structure. In this embodiment, the locking nut I4 is a square nut. The head limiting ring 32 limits one set of opposite sides of the square nut, and the U-shaped structure limits the other set of opposite sides of the square nut, ensuring that the locking nut I4 is accurately positioned within the head limiting ring 32. This, in turn, ensures that the through hole I on the head limiting ring 32 corresponds accurately to the position of the locking nut I4, facilitating bolt installation.

[0024] Furthermore, the lower part of the copper busbar fixing sleeve is integrally connected with a nut mounting groove 23, which is located on one side of the copper busbar body. A locking nut II 5 is provided within the nut mounting groove 23. A through hole II is provided on the copper busbar body, and the locking nut II 5 corresponds to the position of the through hole II. When the copper busbar body is connected to the conductor, a bolt passes through the through hole II and connects to the locking nut II 5. The end of the conductor is wound around the bolt. Tightening the bolt ensures tight contact between the end of the conductor and the copper busbar body, guaranteeing a stable conductor connection while meeting the high-current requirements of the connector.

[0025] Furthermore, such as Figure 3 , Figure 4 As shown, a hook 24 is elastically connected to the copper busbar fixing sleeve, and a limiting hole 31 is provided on the copper busbar body. The hook 24 cooperates with the limiting hole 31. After the copper busbar 3 is installed in place in the copper busbar fixing sleeve, the hook 24 is engaged in the limiting hole 31. At this time, the copper busbar fixing sleeve limits the copper busbar 3 in four directions (front, back, left, and right), and the hook 24 limits the copper busbar 3 in the up and down direction, ensuring that the copper busbar 3 is accurately installed in the copper busbar fixing sleeve and that the copper busbar 3 is installed stably.

[0026] Example 2 differs from Example 1 in that the upper cover connecting plate has a square structure, with fixing holes 21 at the four corners of the square structure, and fixing bolts passing through the fixing holes 21. The fixing bolts pass through the fixing holes 21 and connect to the housing, thereby fixing the energy storage connector to the housing.

[0027] Furthermore, a positioning plate is provided on the upper surface of the upper cover connecting plate, and the positioning plate cooperates with the inner wall of the upper cover 10; the positioning plate is set at the four corners of the square structure. The upper cover 10 has a cross-shaped structure, and a conductive output groove 11 is provided at one end of the cross-shaped structure. In this embodiment, the positioning plate is an arc-shaped plate, and the four inner corners of the upper cover 10 are all arc-shaped. The positioning plate is positioned by the four inner corners of the upper cover 10 to ensure that the upper cover 10 is accurately installed on the base assembly 20; and the positioning plate is centrally symmetrically arranged, that is, the upper cover 10 can be installed in four directions on the base assembly 20, which facilitates the installation of the upper cover 10 according to the wire direction after wiring, and enhances the applicability of the energy storage connector.

[0028] Furthermore, each of the four edges of the square structure is provided with a mounting platform 22 at its center, and the upper cover 10 is provided with two oppositely arranged hanging rings 12, which are connected to the mounting platforms 22. The two hanging rings 12 are connected to the two oppositely arranged mounting platforms 22, and the four mounting platforms 22 are centrally symmetrically arranged, thus giving the upper cover 10 four installation directions relative to the square structure, enabling the energy storage connector to be suitable for outgoing lines in multiple directions.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
