Description

Technical Field

[0001] This utility model belongs to the field of fixed support technology, specifically relating to a splicing fixed support for integrated busbars. Background Technology

[0002] With the rapid development of the new energy market, the demand for large modules in power and energy storage batteries is increasing. Consequently, CCS (integrated busbars) need to be designed to be longer. However, longer CCSs require new molds for their mounting brackets, which are costly. To reduce mold costs while meeting the demand for larger sizes, existing CCS mounting brackets use a splicing structure. However, existing splicing structures often have unidirectional fixation, resulting in poor splicing effects; or some structures are fixed in multiple directions, but the fixation effect in some directions is poor. Utility Model Content

The top and bottom surfaces of the plug plate are respectively limited and engaged with the bottom surface of the first limiting hook and the top surface of the limiting plate. Each second limiting hook is engaged with a corresponding first limiting hook to limit the displacement of two adjacent splicing brackets along the length direction of the fixed bracket.

[0007] Preferably, the plug-in plate and the multiple second limiting hooks are integrally formed.

[0008] Preferably, the contact surfaces of two adjacent splicing brackets are stepped.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model discloses a splicing fixed bracket. Two adjacent splicing brackets are provided, one with a first splicing structure and the other with a second splicing structure. The first splicing structure includes a limiting plate and multiple first limiting hooks, located above the limiting plate.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] A splicing fixing bracket for integrated busbars, see [link / reference]. Figures 1-3 The system includes multiple splicing brackets 1. The end faces of two adjacent splicing brackets 1 are respectively provided with a first splicing structure 2 and a second splicing structure 3. Preferably, the first splicing structure 2 and the second splicing structure 3 are integrally formed with the corresponding splicing bracket 1. The first splicing structure 2 includes a limiting plate 21 and multiple first limiting hooks 22. The multiple first limiting hooks 22 are located above the limiting plate 21, and the bottom surfaces of all the first limiting hooks 22 are coplanar. An insertion groove 23 is formed between the limiting plate 21 and the first limiting hooks 22. The second splicing structure 3 includes an insertion plate 31 and multiple second limiting hooks 32. The insertion plate 31 is inserted into the insertion groove 23. The top and bottom surfaces of the insertion plate 31 respectively limit and cooperate with the bottom surface of the first limiting hook 22 and the top surface of the limiting plate 21. In this way, the two splicing brackets 1 are mutually limited in height. Preferably, the insertion plate 31 abuts against the first limiting hooks 22 and the limiting plate 21, which improves the connection reliability and the strength of the fixed bracket after connection. Each second limiting hook 32 engages with a corresponding first limiting hook 22 to restrict the displacement of two adjacent splicing brackets 1 along the length direction of the fixed bracket. After multiple first limiting hooks 22 and multiple second limiting hooks 32 cooperate, two adjacent clamping plates 24 are also restricted along the width direction of the fixed bracket. The above fixed bracket enables two adjacent splicing brackets 1 to achieve mutual restriction in six directions through the first splicing structure 2 and the second splicing structure 3, ensuring reliable and stable connection.

[0025] There are two first limiting hooks 22, with their hooks facing opposite directions. Of course, the number of first limiting hooks 22 can also be other, and the hooks can also be set to face each other.

[0026] In this embodiment, the plug plate 31 and the multiple second limiting hooks 32 are integrally molded structures, preferably by injection molding. This makes the second splicing structure 3 compact, easy to design, and easy to process.

[0027] In this embodiment, the contact surfaces of two adjacent splicing brackets 1 are stepped. The stepped contact surfaces enable the two splicing brackets 1 to be further limited along the width direction of the fixed bracket after they are connected, which further improves the connection limiting effect and connection reliability.

[0028] Among them, the contact surfaces of two adjacent splicing brackets 1 are provided with two sets of first splicing structures 2 and second splicing structures 3. Of course, only one set of the above-mentioned first splicing structure 2 and second splicing structure 3 can be set, or other existing plug-in structures can be set after setting the above-mentioned set of structures.

[0029] In this embodiment, the first splicing structure 2 further includes two locking plates 24, the bottom surfaces of which are coplanar with the bottom surfaces of the first limiting hooks 22. Each locking plate 24 has at least one locking groove 241, preferably only one, which ensures the structural strength of the locking plate 24 and avoids insufficient strength due to too many locking grooves 241. Multiple first limiting hooks 22 are located between the two locking plates 24, and the plug-in plate 31 has locking blocks 33 that cooperate with the locking grooves 241. By setting the locking plates 24, the top of the plug-in plate 31 can be limited not only by the first limiting hooks 22 but also by the locking plates 24, which reduces the force on the first limiting hooks 22 and improves their service life. At the same time, the cooperation between the locking grooves 241 on the locking plates 24 and the locking blocks 33 on the plug-in plate 31 further restricts the displacement of two adjacent splicing brackets 1 along the length direction of the fixed bracket, improving the connection reliability.

[0030] The top surface of the card block 33 is a guide surface 331, and one end of the guide surface 331 extends to the plug plate 31. This facilitates the insertion of the plug plate 31 into the plug slot 23 and avoids interference between the card block 33 and the card plate 24, which would affect the insertion.

[0031] In this embodiment, the first splicing structure 2 further includes a first limiting rib 25, the bottom surface of which is coplanar with the bottom surface of the first limiting hook 22. The second splicing structure 3 further includes a second limiting rib 34 located on both sides of the first limiting rib 25. Through the cooperation of the first limiting rib 25 and the second limiting rib 34, the displacement of two adjacent splicing brackets 1 along the width direction of the fixed bracket can be further restricted, thereby improving the connection reliability.

[0032] In this embodiment, the fixed bracket formed by multiple splicing brackets 1 is provided with a receiving groove 4 and multiple guide component mounting grooves 5 located on both sides of the receiving groove. The receiving groove is used to install FPC or to carry out wiring. The guide component mounting groove is used to install guide components 3. Each guide component mounting groove is provided with two clearance holes 6 for the guide component to connect with the battery cell of the battery module.

[0033] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
