Description

Technical Field

[0001] This utility model belongs to the technical field of battery module protective cover, specifically relating to a protective cover with a tightening mechanism. Background Technology

[0002] A protective cover for battery terminals is a component specifically designed to cover battery terminals. It is usually made of insulating materials such as plastic and rubber to prevent the battery terminals from contacting external conductors, avoid short circuits, ensure the safety and stability of battery use, isolate air, moisture and other corrosive substances, reduce the possibility of oxidation and corrosion of the terminals, and extend the battery's lifespan.

[0003] In the daily application and maintenance of battery modules, protective covers play a crucial role, shielding and protecting the terminals and wiring from external interference to maintain stable operation. However, traditional protective covers have certain drawbacks in their design and use. These covers require precise fitting to the terminal dimensions, connecting through specific openings. However, during actual assembly and use, gaps often appear between the cover and the terminals due to manufacturing deviations, component aging, and deformation. Once these gaps appear, during charging and discharging, heat is generated at the terminals due to current transmission, and thermal convection occurs within the gaps, causing a rapid rise in local temperature. Excessive temperature softens the cover material and can even lead to melting. This not only weakens the cover's protective capability against the terminals and wiring, exposing the terminals and increasing the risk of short circuits, but also significantly shortens the cover's lifespan, increases battery module maintenance costs, and reduces the overall stability and reliability of the battery system. Utility Model Content

[0004] The purpose of this invention is to provide a protective cover with a tightening mechanism, aiming to solve certain drawbacks in the design and use of traditional battery mold protective covers in the prior art. These protective covers need to be precisely fitted to the terminal post size, connecting with the post through a specific opening. However, in actual assembly and use, due to manufacturing process deviations, component aging and deformation, gaps often appear between the protective cover and the terminal post. Once these gaps appear, during the charging and discharging process of the battery module, the terminal post will generate heat due to current transmission, and thermal convection will occur within the gaps, causing a rapid rise in local temperature. Excessive temperature will cause the protective cover material to gradually soften, and may even lead to high-temperature melting.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a protective cover with a tightening mechanism, comprising a protective cover body and a retaining plate installed on one side, wherein a buckle plate is connected to one side of the bottom surface of the protective cover body, and a through cylinder is installed on the surface of the buckle plate;

[0006] The inner wall of the through cylinder is connected to a rubber pad, the bottom end of the rubber pad is connected to a bottom support sleeve, the top end of the rubber pad is connected to a top support sleeve, the inner side of the top support sleeve is connected to an upper mounting strip, the inner wall of the bottom support sleeve is connected to a lower mounting strip, and the surface of the through cylinder near the upper and lower mounting strips respectively has an upper mounting groove and a lower mounting groove.

[0007] As a preferred embodiment of the protective cover with a tightening mechanism of this utility model, the inner wall of the rubber pad is connected with a set of protruding strips, and the set of protruding strips are circumferentially distributed about the center line of the rubber pad.

[0008] As a preferred embodiment of the protective cover with a tightening mechanism of this utility model, the upper mounting strip and the lower mounting strip are respectively sleeved on the upper and lower ends of the through cylinder, and the rubber pad, the bottom support sleeve and the top support sleeve are an integral structure.

[0009] As a preferred embodiment of the protective cover with a tightening mechanism of this utility model, the upper mounting strip and the lower mounting strip are respectively fitted and connected to the upper mounting groove and the lower mounting groove.

[0011] As a preferred embodiment of the protective cover with a tightening mechanism of this utility model, the mating end of the reinforced side plate is connected to a socket, the mating end of the reinforced mating plate is connected to a plug, the plug and the opening at one end of the socket are fitted together, and the bottom surface of the reinforced horizontal plate is threaded with a PVC locking pin.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention involves attaching a rubber pad to the inner wall of a through-tube on the surface of the protective cover. The bottom and top supports are then adjusted to their respective ends. The upper and lower mounting strips are then aligned with the upper and lower mounting grooves to ensure stable installation of the rubber pad. At this point, the protruding strips contact the battery module and wires, facilitating a tight fit and tightening of the protective cover. This ensures close contact between the protective cover and the battery module terminals and wires. Furthermore, the use of rubber material enhances high-temperature resistance, preventing the protective cover from melting and extending its lifespan. Attached Figure Description
