Description

Technical Field

[0001] The utility model relates to the technical field of CCA products, in particular to a battery connector assembly. Background Art

[0002] The battery connector assembly is CELL CONNECTOR ASSEMBLY, referred to as CCA. CCA products are mainly used for the connection mechanism at the extreme ends of square shell batteries. They are used as connectors between single cells. Through the arrangement of CCA, they are welded to the batteries to achieve series and parallel connection of batteries, so as to achieve the improvement of voltage and energy of the battery pack.

[0003] With the development of new energy batteries, the length of CCA as a connector is gradually getting longer. For CCA produced by hot pressing, products with a length of about 1500mm can use ordinary molds and general hot pressing equipment to ensure dimensional tolerance. However, when the length of CCA exceeds 1500mm, the requirements for hot pressing equipment and molds will also increase, and the existing production method cannot meet the production needs of large-size CCA. Because if the original method is still used, at least two conditions need to be met at the same time: ① It is necessary to purchase large-size hot pressing equipment to put down long products; ② The strength and rigidity of the mold need to be improved, so as to ensure that the mold does not deform during the hot pressing process to ensure the dimensional tolerance of the product. In actual production, if an enterprise wants to achieve these two conditions at the same time, the cost of the product will be greatly increased, and the tolerance of the product size is not easy to control. Utility Model Content

[0004] The technical problem solved by the utility model is to provide a battery connector assembly for solving the problems of high cost and difficult control of product tolerance in large-size CCA processing.

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: a plurality of sections of CCA main body are connected into a whole by heat pressing.

[0006] Preferably, several sections of the CCA body are connected by heat pressing through a polyester heat pressing film.

[0007] Preferably, the polyester hot-pressed film comprises an upper film and a lower film, and the upper film and the lower film are in an "I" shape.

[0008] Preferably, a circular hole is provided on the upper membrane and the lower membrane.

[0009] Preferably, a semicircular opening 1 is provided at one end of the CCA body, and a similar semicircular opening 2 is provided at one end of the adjacent correspondingly connected CCA body, and the semicircular opening 1 is in corresponding contact with the semicircular opening 2 to form a complete circular hole 2.

[0010] Preferably, the circular hole 2 formed by the semicircular opening 1 and the semicircular opening 2 corresponds to the circular hole 1.

[0011] Preferably, the CCA body is wrapped with aluminum sheets and an insulating film, and the aluminum sheets are hot-pressed in the insulating film and arranged regularly.

[0012] Preferably, the insulating film comprises an upper insulating film and a lower insulating film, and the upper insulating film and the lower insulating film are hot-pressed into one.

[0013] The beneficial effects of the utility model are:

[0014] (1) The utility model discloses a battery connector assembly. After a CCA body is hot-pressed and formed, several sections of the CCA body are hot-pressed together using a polyester hot-pressing film, thereby reducing the difficulty of processing and producing large-size CCAs exceeding 1500 mm in the prior art, and solving the problems of poor control of dimensional tolerance and high cost in producing large-size CCAs.

[0015] (2) In the present invention, subassembly A and subassembly are hot-pressed together by a polyester hot-pressing film. Through a semicircular hole opened on the CCA, the same semicircular opening 2 is also opened at one end of the adjacent correspondingly connected CCA body. The semicircular opening 1 is in contact with the semicircular opening 2 to form a complete circular hole 2. The circular hole 2 corresponds to the circular hole 1. During the hot-pressing process, the hot-pressing wrapping through the circular hole is tighter and the connection is more complete, which will not affect the quality of the product.

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be better understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0022] Example:

[0023] This embodiment introduces the structure of a battery connector assembly for illustration.

[0024] As attached Figure 1 As shown, Figure 1 The utility model is a structural schematic diagram of a battery connector assembly.

[0025] In this embodiment, the structure of the battery connector assembly is described by taking the connection of two sections of CCA body as an example. A battery connector assembly includes: a subassembly A1 and a subassembly B2, wherein the subassembly A1 and the subassembly B2 are connected together by hot pressing of a polyester hot pressing film to form a large-sized CCA product.

[0026] like Figure 2 As shown, Figure 2 1 is a schematic diagram of an exploded view of a battery connector assembly. In this embodiment, the polyester hot pressing film includes an upper film 4 and a lower film 5, and the upper film 4 and the lower film 5 are in an "I" shape, tightly covering the subassembly A1 and the subassembly B2 to form a complete whole.

[0027] like Figure 3 As shown, Figure 3 It is a partial schematic diagram of a battery connector assembly shown. In order to make the subassembly A1 and the subassembly B2 more tightly connected and integrated during the hot pressing of the polyester hot pressing film, a circular hole 8 is opened on the upper film 4 and the lower film 5; a semicircular opening 9 is opened at one end of the subassembly A1, and the same semicircular opening 2 10 is opened at one end of the adjacent corresponding subassembly B2, and the semicircular opening 1 9 and the semicircular opening 2 10 are in contact with each other to form a complete circular hole 2. The circular hole 2 formed by the semicircular opening 1 9 and the semicircular opening 2 10 corresponds to the circular hole 1 8. During the hot pressing process, the hot pressing through the circular hole has a tighter coverage and a more complete connection.

[0028] Furthermore, the CCA body includes aluminum tabs 3, which are hot pressed in the subassembly A1 and the subassembly B2 and arranged regularly.

[0029] Furthermore, the insulating film includes an upper insulating film 6 and a lower insulating film 7, and the upper insulating film 6 and the lower insulating film 7 are hot pressed into one.

[0030] In this embodiment, subassembly A and subassembly B are subjected to heat pressing treatment respectively, and then subassembly A and subassembly B are connected as a whole by heat pressing with polyester heat pressing film, so as to realize the processing of large-size CCA exceeding 1500mm. The segmented processing and then combined method solves the problems of poor control of dimensional tolerance and high cost in the production of large-size CCA while ensuring product quality.

[0031] Example 2

[0032] Based on the above embodiment, this embodiment briefly describes the process of processing the CCA body at both ends to form a large-size CCA:

[0033] (1) Prepare materials: prepare aluminum sheet 3, upper insulating film 6, lower insulating film 7, upper film 4, and lower film 5;

[0034] (2) Hot pressing to form a two-stage assembly: Place the upper insulating film 6, the aluminum sheet 3, and the lower insulating film 7 into the mold in sequence; Place the mold into a hot press and hot press to form the CCA body;

[0035] (3) Use polyester hot pressing film to hot press and connect the two sections of the CCA body: put the lower film 5, subassembly A1, and subassembly B2 into the mold respectively. After the subassembly A1 and subassembly B2 are firmly positioned on the lower film 5, put the upper film 4 into the mold and cover the subassembly A1 and subassembly B2; put the mold into a hot press machine and combine them into a large-sized CCA product through hot pressing.

[0036] In this embodiment, the processing of two-stage CCA products is taken as an example. The above method can be used to adapt to different production needs and the production of CCA of different large sizes. After use in actual production, the above production method has greatly improved production efficiency and will not increase additional production costs. Based on the dimensional tolerance and cost analysis of large-size CCA, the product is segmented and reconnected on the premise of meeting customer functional requirements, and the production process is optimized, which does not affect the product qualification rate, and effectively solves the problem of meeting product dimensional tolerances and the high production cost of large hot presses, thereby reducing production costs and improving the company's production efficiency.
