Description

Technical Field

[0001] This utility model relates to the field of stud-type energy storage terminals, specifically a stud-type energy storage terminal. Background Technology

[0002] In electrochemical energy storage systems, stud-type energy storage terminals are key components for electrical connection between battery modules, battery clusters and combiner devices. Their core function is to provide a high-current, highly reliable connection point.

[0003] Traditional stud-type terminals typically use an insulated shell of fixed height, and the internal space of the shell is not adjustable. When the connector is thin, the internal space is wasted, resulting in a large overall size of the terminal. When the connector is thick or there are many connectors, the shell may not be able to completely cover them, which may lead to the safety risks of electric shock and short circuit. Therefore, a stud-type energy storage terminal is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a stud-type energy storage terminal block to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A stud-type energy storage terminal block includes a mounting plate. A socket is fixedly connected to the center of the mounting plate. A threaded post and a threaded seat are fitted into the socket. The threaded post and the threaded seat are integrally formed. An insulating protective lower shell is snapped onto the upper end of the socket. An insulating protective upper shell is slidably inserted onto the insulating protective lower shell. A snap-fit ​​component is provided on the side wall of the insulating protective lower shell. Multiple sets of slots are opened on the inner wall of the insulating protective upper shell. The snap-fit ​​component engages with the slots.

[0007] Preferably, the side wall of the insulating protective lower shell is provided with a slot, and the snap-fit ​​assembly includes a spring plate. One end of the spring plate is fixedly connected to the inner wall of the slot, and the other end is located in the slot and fixedly connected to a protrusion. The protrusion protrudes out of the slot and engages with the snap-fit.

[0008] Preferably, the bottom of the insulating protective lower shell has an installation opening, and the side wall of the socket has an annular groove. The annular groove is coaxial with the socket, and the side wall of the installation opening is engaged with the annular groove.

[0009] Preferably, the threaded post has a through-hole with a lower threaded opening located below the socket, and the threaded seat has an upper threaded opening.

[0010] Preferably, the socket has a mounting groove on its side wall, a mounting block is inserted into the mounting groove, a pressure plate is rotatably mounted on the upper end of the mounting block, and one end of the pressure plate is pressed against the upper end of the threaded seat.

[0011] Preferably, a reinforcing rib is fixed between the socket and the mounting plate, and multiple sets of reinforcing ribs are provided, with the multiple sets of reinforcing ribs arranged in a circumferential array.

[0012] The beneficial effects of this utility model are:

[0013] This invention uses a sliding insulating protective lower shell and an insulating protective upper shell, and then a snap-fit ​​assembly is snapped into the snap-fit ​​slot. This allows the total height of the entire insulating shell to be adjusted and fixed, thereby changing the internal space of the insulating shell. This enables the terminal block to be compatible with cable terminals or copper busbars of different thicknesses and layers, improving the versatility and adaptability of the energy storage terminal block.

Detailed Implementation

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

[0022] A stud-type energy storage terminal, such as Figures 1-4As shown, the device includes a mounting plate 1, a socket 2 fixedly connected to the middle of the mounting plate 1, a threaded post 3 and a threaded seat 4 fitted into the socket 2, the threaded post 3 and the threaded seat 4 being integrally formed to form the core conductive body of the terminal block, an insulating protective lower shell 9 snapped onto the upper end of the socket 2, an insulating protective upper shell 14 slidingly inserted onto the insulating protective lower shell 9, a snap-fit ​​assembly provided on the side wall of the insulating protective lower shell 9, and multiple sets of latches 15 opened on the inner wall of the insulating protective upper shell 14, the snap-fit ​​assembly engaging with the latches 15, the multiple sets of latches 15 being arranged in a linear array from top to bottom.

[0023] By sliding the upper insulating shell 14 on the lower insulating shell 9, the total height of the entire insulating shell can be adjusted. Then, the snap-fit ​​assembly is snapped into the corresponding snap-fit ​​slot 15 to position the lower insulating shell 9 and the upper insulating shell 14, thereby changing the internal space of the insulating shell. This allows the terminal block to be compatible with cable terminals or copper busbars of different thicknesses and layers, improving the versatility and adaptability of the energy storage terminal block.

[0024] The side wall of the insulating protective lower shell 9 has a slot 11. The snap-fit ​​assembly includes a spring plate 12. One end of the spring plate 12 is fixed to the inner wall of the slot 11, and the other end is located in the slot 11 and fixed with a protrusion 13. The protrusion 13 protrudes out of the slot 11 and engages with the snap-fit ​​15. When the insulating protective upper shell 14 slides relative to the insulating protective lower shell 9, it will squeeze the protrusion 13, causing the spring plate 12 to bend into the insulating protective lower shell 9. When the protrusion 13 at the end of the spring plate 12 engages with the snap-fit ​​15, a "click" positioning feeling is generated, the spring plate 12 is reset, and the insulating protective upper shell 14 and the insulating protective lower shell 9 are positioned.

[0025] The bottom of the insulating protective lower shell 9 has an installation port 10, and the side wall of the socket 2 has an annular groove 5. The annular groove 5 is coaxial with the socket 2, and the side wall of the installation port 10 is engaged with the annular groove 5.

[0026] One end of the mounting port 10 penetrates one end of the insulating protective lower shell 9. The width of the mounting port 10 is smaller than the diameter of the socket 2. The width of the mounting port 10 is similar to the diameter of the inner ring of the annular groove 5, so that the socket 2 can be inserted into the mounting port 10.

[0027] A lower threaded opening 18 is provided through the threaded post 3, which is located below the socket 2. An upper threaded opening 17 is provided on the threaded seat 4. The lower threaded opening 18 and the upper threaded opening 17 are used to connect cable terminals. When wiring, the positive cable terminal from the battery module can be inserted into the lower threaded opening 18 and tightened with a nut. The cable terminal from the busbar can be inserted into the upper threaded opening 17 and tightened with another nut, thereby realizing the collection and transmission of current.

[0028] The side wall of the socket 2 has an installation groove 6, and an installation block 7 is inserted into the installation groove 6. A pressure plate 8 is rotatably installed on the upper end of the installation block 7. One end of the pressure plate 8 presses against the upper end of the threaded seat 4. Rotating the pressure plate 8 can press one end of the pressure plate 8 against the upper end of the threaded seat 4, preventing the threaded post 3 from falling off the socket 2, and the installation block 7 is easy to disassemble and assemble.

[0029] A reinforcing rib 16 is fixedly connected between the socket 2 and the mounting plate 1. Multiple sets of reinforcing ribs 16 are provided and arranged in a circumferential array. The reinforcing ribs 16 enhance the connection strength between the socket 2 and the mounting plate 1.

[0030] The working principle of the stud-type energy storage terminal provided by this utility model is as follows:

[0031] During wiring, slide the upper insulating protective shell 14 upward to separate it from the lower insulating protective shell 9, exposing the internal threaded seat 4. Connect the threaded seat 4 and the threaded post 3. After completing the wiring, slide the upper insulating protective shell 14 downward until the space inside the insulating shell is just right. At this time, the protrusion 13 of the snap-fit ​​component will snap into the corresponding slot 15, locking the upper insulating protective shell 14. The live metal parts are completely enclosed in the insulating cavity formed by the lower insulating protective shell 9 and the upper insulating protective shell 14, which is safe and reliable.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
