Description

Technical Field

[0001] This utility model belongs to the field of thermal battery technology, and in particular relates to a thermal battery cover assembly. Background Technology

[0002] A thermal battery cover is an essential structure in thermal battery technology, used to connect the lead wires and current guides. The battery cover connects to the lead wires and current guides via terminals, but the connection points are usually exposed and unprotected, making them susceptible to damage from impacts or other factors, resulting in the breakage of the lead wires and current guides. Therefore, a thermal battery cover assembly is needed to protect these connection points. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a thermal battery cover assembly.

[0004] This utility model is achieved through the following technical solution.

[0005] This utility model provides a thermal battery cover assembly, including a cover plate and a protective cover, which are connected together. The cover plate is provided with a terminal post and a stud. A guide strip or wire is connected to the terminal post, and a screw is provided on the stud. The protective cover is provided with a mounting hole. The screw passes through the mounting hole and is threadedly connected to the stud, so that the cover plate and the protective cover are firmly connected.

[0006] Preferably, an intermediate layer is provided on the cover plate, and the pole post and stud pass through the intermediate layer and are connected to the cover plate.

[0007] Preferably, a gasket is fitted on the pole post, the gasket being positioned below and above the guide strip or wire, and a nut is threaded onto the pole post, the nut being positioned above the uppermost gasket.

[0008] Preferably, the pole is connected to the cover plate via a pad.

[0009] Preferably, an inner cavity is provided on one side of the protective cover.

[0010] Preferably, the protective cover has a first outlet and a second outlet on its side.

[0011] Preferably, the mounting hole is a countersunk hole.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention protects the wires and current-guiding strips on the battery cover assembly with a protective cover, preventing damage to these components under stress and improving the structural strength of the battery cover assembly, thereby enhancing the quality stability of the thermal battery. The padding layer prevents short circuits by eliminating conductivity between the terminals and the cover plate. The studs and screws improve the stability of the connection between the cover plate and the protective cover. The protective cover also safeguards the connection points between the internal terminals and the wires and current-guiding strips, improving the durability of the thermal battery.

[0020] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0021] Example:

[0022] like Figures 1 to 5 As shown, a thermal battery cover assembly includes a cover plate 1 and a protective cover 2, which are connected. The cover plate 1 has an electrode post 3 and a stud 4. A guide strip 5 or a wire 6 is connected to the electrode post 3. A screw 7 is provided on the stud 4. The protective cover 2 has a mounting hole 21. The screw 7 passes through the mounting hole 21 and is threadedly connected to the stud 4, thus securing the cover plate 1 and the protective cover 2. This thermal battery cover assembly is a thermal battery cover assembly without an electric ignition head.

[0023] An intermediate layer 11 is provided on the cover plate 1. The pole post 3 and the stud 4 pass through the intermediate layer 11 and are connected to the cover plate 1. The intermediate layer 11 is made of mica sheet and has an insulating effect, which can prevent the guide strip 5 and the wire 6 from contacting the metal cover plate 1 and causing conduction.

[0024] A gasket 31 is fitted onto the pole post 3. The gasket 31 is positioned below and above the guide strip 5 or the wire 6 to protect the guide strip 5 and the wire 6 from being scratched by the nut or the intermediate layer 11. A nut 9 is threaded onto the pole post 3. The nut 9 is located above the uppermost gasket 31 and is used to fix the guide strip 5 and the wire 6 to the pole post 3.

[0025] The pole post 3 is connected to the cover plate 1 through the pad 8. The pad 8 is made of molybdenum glass, and the molybdenum glass and the cover plate 1 are sintered together to form an insulating layer.

[0026] The protective cover 2 has an inner cavity 22 on one side, which is used to cover the connection of the pole post 3, the stud 4 structure, the guide strip 5, and the wire 6, and plays a protective role.

[0027] The protective cover 2 is provided with a first outlet 23 and a second outlet 24 on its side. The first outlet 23 is used for the guide strip 5 to be led out, and the second outlet 24 is used for the wire 6 to be led out.

[0028] The mounting hole 21 is a countersunk hole to prevent the screw 7 from protruding from the surface of the protective cover 2 and making contact with other structures to create conductivity.
