Description

Technical Field

[0001] This utility model relates to the field of temperature fuses, and in particular to a dual fuse tube assembly. Background Technology

[0002] Current temperature fuses have a relatively simple structure, often with only one fuse operating. If this fuse fails, the equipment cannot be protected. However, by incorporating two fuses within the same fuse tube assembly, safety can be improved, allowing the device to continue functioning even if only one fuse fails. Utility Model Content

[0003] The main objective of this invention is to provide a dual fuse tube assembly that improves the safety of equipment use by setting two fuses in the same fuse tube assembly.

[0004] This utility model proposes a dual-fuse tube assembly, including a housing, a first thermal fuse, a second thermal fuse, a first connecting wire, a second connecting wire, a third connecting wire, and a fourth connecting wire;

[0005] The first temperature fuse and the second temperature fuse are arranged one after the other in the housing, and the first temperature fuse and the second temperature fuse are sealed in the housing by a thermally conductive potting layer.

[0006] The first thermal fuse is connected to the first connecting line and the second connecting line at both ends, and the second thermal fuse is connected to the third connecting line and the fourth connecting line at both ends. The first thermal fuse and the second thermal fuse are connected to the main circuit. By setting the first thermal fuse and the second thermal fuse, the safety of use can be improved.

[0007] Preferably, it further includes two connecting terminals, one end of the first connecting line and the third connecting line being connected to the connecting terminals respectively.

[0008] Preferably, it further includes a fixing connector, which is fixedly connected to the shell by welding. The fixing connector is provided with a fixing hole, and the fixing connector can be connected to an external structure through the fixing hole.

[0009] Preferably, it further includes a fifth connecting wire, which is a ground wire and is connected to the fixed connector, and leakage protection is provided through the fifth connecting wire.

[0010] Preferably, it also includes heat shrink tubing, which is sleeved on the outside of the first connecting line and the third connecting line.

[0011] The beneficial effects of the double fuse tube assembly of this utility model are as follows:

[0012] By setting up a first temperature fuse and a second temperature fuse, a double safety measure can be implemented, thereby improving safety during use.

[0013] By setting the fifth connection wire as the ground wire, the function of leakage protection can be achieved. Attached Figure Description
