Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of battery packs, and particularly relates to a plastic suction structure with an output pole insulation protection. Background Technique
[0002] The CCS lithium battery is a lithium battery module equipped with CCS. Each lithium battery module contains a CCS module. The CCS module is an integrated module formed by connecting 1-2 flexible circuit boards, plastic and other material structures, and copper-aluminum bars. This integrated module is the Cells Contact System, abbreviated as CCS.
[0003] At present, the output pole insulation protection in the battery pack mainly adopts injection molded parts, which are fixed above the output pole base. Since the upper cover is composed of two parts, the cost is relatively high and the mold opening cycle is relatively long, which is 25-30 days.
[0004] Therefore, in view of this, in view of the deficiencies of the existing structure, research and improvement are carried out, and a plastic suction structure with an output pole insulation protection is proposed. Content of the Utility Model
[0005] The purpose of the utility model is to provide a plastic suction structure with an output pole insulation protection, so as to solve the problems put forward in the above background technique.
[0006] To achieve the above purpose, the utility model provides the following technical solution: a plastic suction structure with an output pole insulation protection, including a plastic suction cover. The two sides of the plastic suction cover are symmetrically bent with clamping parts, and two protruding parts are raised in the middle of the plastic suction cover. Output pole bases are symmetrically arranged on both sides of the plastic suction cover, and a connecting piece is fixedly connected to the root of the output pole base. An output pole mark is correspondingly arranged at the root of the connecting piece. Output pole ears are symmetrically arranged on both sides of the plastic suction cover, and a reinforcing rib is connected to the root of the output pole ear.
[0007] Further, the plastic suction cover is a cover body processed from plastic materials into a predetermined shape through a plastic suction process, and the plastic suction cover is placed above the copper bar to play an insulating effect.
[0008] Further, the clamping parts on both sides of the plastic suction cover are made of elastic materials, and the plastic suction cover is clamped with the copper bar support base through the clamping parts.
[0009] Further, the output pole base is riveted and fixed to the plastic suction cover through the connecting piece fixedly connected to the root, and a notch for avoiding the output pole mark is provided at the root of the connecting piece.
[0010] Further, the arrangement of the reinforcing rib enables the output pole ear to be folded, and the reinforcing rib is made of an anti-fatigue elastic material.
[0011] Further, the output terminal ears cover both sides of the output terminal base, and the output terminal ears are folded to avoid interference when installing the copper busbar.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] 1. When the utility model is in use, the separate injection molded part in the prior art is removed, and the output terminal ears are directly added to the plastic suction cover, covering both sides of the output terminal base to play an insulating and protective effect. In order to ensure that the cover does not deform when installing the copper busbar, a reinforcing rib is added to the output terminal ears, so that the output terminal ears can be folded. Through the above design, the development cost can be effectively reduced, and the mold opening cycle can be shortened to 8 - 10 days. Through the flip design of the output terminal ears, local deformation and irreversible phenomenon after the upper cover is folded will not occur.
[0014] 2. When the utility model is in use, the plastic suction cover of the present application is processed into a cover body with a predetermined shape by a plastic suction process. By bending both sides of the plastic suction cover into elastically deformable clamping parts, it can be directly clamped with the copper busbar support base, effectively reducing the production cost while ensuring stable connection.

[0019] The following further describes in detail the embodiments of the utility model with reference to the drawings and examples. The following examples are used to illustrate the utility model, but cannot be used to limit the scope of the utility model.
[0020] As Figures 1 to 3As shown in the figure, a plastic suction structure with built-in output pole insulation protection includes a plastic suction cover 1. The plastic suction cover 1 is a cover body processed from plastic materials into a predetermined shape through the plastic suction process, and the plastic suction cover 1 is placed above the copper row to achieve an insulation effect. In this application, the plastic suction cover 1 is a cover body processed from plastic materials into a predetermined shape through the plastic suction process. By bending the two sides of the plastic suction cover 1 into elastically deformable clamping parts 2, it can be directly clamped with the copper row support base, effectively reducing production costs while ensuring stable connection. The materials of the clamping parts 2 on both sides of the plastic suction cover 1 itself have elasticity, and the plastic suction cover 1 is clamped with the copper row support base through the clamping parts 2. There are symmetrically bent clamping parts 2 on both sides of the plastic suction cover 1, and there are two raised parts 3 bulging in the middle of the plastic suction cover 1. Output pole bases 4 are symmetrically arranged on both sides of the plastic suction cover 1, and a connecting part 5 is fixedly connected to the root of the output pole base 4, and an output pole mark 6 is correspondingly arranged at the root of the connecting part 5. The output pole base 4 is riveted and fixed to the plastic suction cover 1 through the connecting part 5 fixedly connected to its root, and a notch for avoiding the output pole mark 6 is provided at the root of the connecting part 5. Output pole ears 7 are symmetrically arranged on both sides of the plastic suction cover 1, and a reinforcing rib 8 is connected to the root of the output pole ears 7. The setting of the reinforcing rib 8 enables the output pole ears 7 to be folded, and the reinforcing rib 8 is made of an anti-fatigue elastic material. The output pole ears 7 cover both sides of the output pole base 4, and when installing the copper row, the output pole ears 7 are folded to avoid. The separately existing injection molded part in the prior art is removed, and the output pole ears 7 are directly added to the plastic suction cover 1, covering both sides of the output pole base 4 to achieve an insulation protection effect. In order to ensure that the cover does not deform when installing the copper row, a reinforcing rib 8 is added to the output pole ears 7, enabling the output pole ears 7 to be folded.
[0021] Working principle: When using this plastic suction structure with built-in output pole insulation protection, the separately existing injection molded part in the prior art is removed, and the output pole ears 7 are directly added to the plastic suction cover 1, covering both sides of the output pole base 4 to achieve an insulation protection effect. In order to ensure that the cover does not deform when installing the copper row, a reinforcing rib 8 is added to the output pole ears 7, enabling the output pole ears 7 to be folded. In this application, the plastic suction cover 1 is a cover body processed from plastic materials into a predetermined shape through the plastic suction process. By bending the two sides of the plastic suction cover 1 into elastically deformable clamping parts 2, it can be directly clamped with the copper row support base, effectively reducing production costs while ensuring stable connection.
