Description

Technical Field

[0001] This utility model relates to the field of insulation protection technology, and in particular to a top insulation protection structure for a vacuum-formed CCS. Background Technology

[0002] CCS has functions such as connecting cells in series and parallel in power batteries, collecting voltage within modules, and sampling temperature within modules. Currently, the main production processes for products on the market include hot pressing, injection molding, and vacuum forming. Among them, vacuum forming has advantages such as high production efficiency and relatively low cost, and is gradually standing out in the fields of new energy vehicles and energy storage.

[0003] In existing passenger vehicle battery packs, the thermoformed CCS consists of a substrate, an aluminum busbar, and a flexible circuit board. After the aluminum busbar is welded to the cell terminals, a high-voltage circuit is formed, requiring insulation protection to meet IPXXB requirements. Existing technologies primarily address this issue by die-cutting PC sheets and then locally bonding them to the aluminum busbar with adhesive. However, the double-sided adhesive used in this solution has insulation problems and cannot meet the PACK insulation withstand voltage requirements, potentially causing rework issues during subsequent product testing. To solve these problems, this application proposes a top insulation protection structure for the thermoformed CCS. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a vacuum-formed CCS top insulating protection structure. Through the double-layer structure design of the insulating protective cover and the insulating plate, combined with the precisely corresponding through holes and snap-fit ​​installation mechanism, it can provide insulating protection for internal conductive components and effectively resist the influence of complex external environments. The high-voltage protection on the upper part of the CCS is fixed with snaps, avoiding the insulation problems that may be caused by using double-sided adhesive, while also meeting the requirements for multiple disassembly and repair.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A thermoformed CCS top insulating protective structure includes a base plate, on which multiple aluminum bars are fixedly connected, and multiple connectors are mounted on the base plate. Two L-shaped folding plates are fixedly connected to the side wall of the base plate, each of which has a through opening. Multiple connector plugs are fixedly connected to the side wall of the base plate. An insulating protective cover is connected to the top of each aluminum bar, and an insulating plate is mounted on the top of the insulating protective cover. Two buckles are fixedly connected to the insulating plate. Two grooves are formed on the base plate, and the two buckles are respectively inserted into the corresponding grooves.

[0007] Preferably, a protrusion is fixedly connected to the substrate, a limiting hole is provided on the connector, the protrusion is disposed through the limiting hole, and the substrate and the protrusion are installed and fixed by adhesive bonding.

[0008] Preferably, the sidewall of the substrate is fixedly connected to two side plates, and each side plate is fixedly connected to two ends with mounting feet, and each mounting foot is fixedly connected to the substrate.

[0009] Preferably, the insulating protective cover has two first through holes, and the aluminum bar has two second through holes. The two first through holes and the two second through holes are arranged in a matching manner, and each of the buckles is arranged through the first through hole and the second through hole respectively.

[0010] Preferably, a limiting block is fixedly connected to the side wall of the buckle, and the limiting block is located in the groove and abuts against its inner wall.

[0011] Preferably, the insulating plate, the insulating protective cover, and the aluminum bar are arranged in close contact.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. The high-voltage protection on the upper part of the CCS is fixed with clips, which avoids the insulation problems that may be caused by using double-sided tape, and at the same time allows for multiple disassembly and repair.

[0014] 2. It avoids the use of double-sided tape, reducing material costs; it also avoids the vacuum forming of the top cover, reducing mold costs.

Multiple connectors 3 are installed on the substrate 1, and protrusions 4 are fixedly connected to the substrate 1. Limiting holes 5 are opened on the connectors 3, and the protrusions 4 are set through the limiting holes 5. The substrate 1 and the protrusions 4 are installed and fixed together by adhesive bonding.

[0022] Two side plates 6 are fixedly connected to the side wall of the substrate 1. The side plates 6 are fixed to the side wall of the substrate 1 and provide lateral support and protection for the substrate 1. Each side plate 6 has a mounting foot 7 fixedly connected to both ends. Each mounting foot 7 is fixedly connected to the substrate 1. The mounting foot 7 is used to firmly connect the side plate 6 to the substrate 1 and facilitates the installation and fixation of the entire structure with external equipment. Two L-shaped folding plates 8 are fixedly connected to the side wall of the substrate 1. The L-shaped folding plates 8 are fixed to the side wall of the substrate 1 and serve to strengthen the structural strength and assist in installation. Each L-shaped folding plate 8 has a through opening 9. Multiple connecting plugs 10 are fixedly connected to the side wall of the substrate 1. The connecting plugs 10 are used to realize electrical connection with external equipment.

[0023] An insulating protective cover 14 is connected to the top of the aluminum bar 2. The insulating protective cover 14 covers the top of the aluminum bar 2, providing insulation and protection to prevent external factors from affecting its normal operation. Two first through holes are formed in the insulating protective cover 14, and two second through holes are formed in the aluminum bar 2. The two first through holes and the two second through holes are designed to cooperate, providing a channel for the installation of the clips 12. Each clip 12 is installed through one of the first through holes and the other of the second through hole. An insulating plate 11 is installed on the top of the insulating protective cover 14. The insulating plate 11 further enhances the insulation protection effect and works in conjunction with the insulating protective cover 14 to protect the aluminum bar 2. The insulating plate 11 is protected by two clips 12. The clips 12 are elastic deformation parts. Two grooves 15 are opened on the base plate 1. The two clips 12 are respectively inserted into the corresponding grooves 15. The clips 12 are inserted into the grooves 15 to connect and fix the insulating plate 11, the insulating protective cover 14 and the base plate 1. The side wall of the clip 12 is fixedly connected to the limiting block 13. The limiting block 13 is located in the groove 15 and abuts against its inner wall. The insulating plate 11, the insulating protective cover 14 and the aluminum bar 2 are tightly abutted. The limiting block 13 cooperates with the groove 15 to limit the clip 12 and prevent it from loosening.

[0024] In this utility model, when it is necessary to provide insulation protection for the aluminum bar 2, the insulation protection cover 14 is placed on the two aluminum bars 2. The operator can insert the two buckles 12 on the insulation plate 11 through the insulation protection cover 14 and the aluminum bar 2 until the two buckles 12 are inserted into the groove 15 opened on the base plate 1. The insulation plate 11 and the two buckles 12 can be limited and fixed by the setting of the limiting block 13 and the groove 15, so that the insulation plate 11 and the aluminum bar 2 clamp the insulation protection cover 14 to ensure the installation and fixation of the insulation protection cover 14. When the buckles 12 and the limiting block 13 are inserted into the groove 15, the operator hears a "click" to indicate that the installation is in place.
