Abstract
The invention discloses a temperature fuse. The fuse comprises two parallel metal electrodes, a fusible alloy wire and a closed cavity, wherein one end of each metal electrode penetrates into the closed cavity; the metal electrodes penetrating into the closed cavity are connected through the fusible alloy wire; special resin is coated on the fusible alloy wire; the fusible alloy wire and the joint between the fusible alloy wire and the two metal electrodes are encapsulated in the closed cavity; the closed cavity comprises a box body and a cover plate; and parts of the two metal electrodes, which are extracted out of the box body, is coated with seal resin at the contact with the box wall. The temperature fuse has the advantages of good seal property of the closed cavity, simple structure, simple manufacture process and cost saving; and the seal resin ensures that the joint of the metal electrodes and the box wall can be fused better.
Description
Technical field
The present invention relates to a kind of fuse, relate in particular to a kind of Thermal Cutoffs.
Background technology
What produce in the improper running of Thermal Cutoffs energy induction apparatus electronic product is overheated, thereby cut-off loop is to avoid the generation of fire.The Thermal Cutoffs major part is the fusible alloy silk; when battery temperature is elevated to the fusible alloy fusing point; the fusing of fusible alloy silk disconnects, thereby cuts off circuit protected cell, usually metal electrode is connected by the fusible alloy silk; the junction is coated with flux again; be sealed to together in the plastic casing, metal electrode enters housing and wants hot adhesion on the housing base plate, under the inappropriate technology situation again; cause bond crack sometimes, influenced the sealing of plastic casing.Therefore, need provide a kind of new technical scheme to solve the problems referred to above.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, the Thermal Cutoffs of function admirable.
Technical scheme provided by the invention:
A kind of Thermal Cutoffs, comprise two metal electrodes that are arranged in parallel, fusible alloy silk and airtight cavity, described two metal electrodes, one end gos deep in the airtight cavity, the described metal electrode that gos deep in the airtight cavity connects by the fusible alloy silk, be coated with special resin on the described fusible alloy silk, described fusible alloy silk and be packaged in the airtight cavity with the connecting portion of two metal electrodes, described airtight cavity comprises box body and cover plate, and external being coated with the box wall contact position of described two metal electrode outlet boxes sealed resin.
Described special resin is a flux, and described flux is filled in the airtight cavity.
Described cover plate is that relative box body is crowned.
Beneficial effect of the present invention: the good airproof performance of airtight cavity, seal resin the contact position of metal electrode and box wall is more merged, simple in structure, manufacturing process is simple, saves cost.
Description of drawings
Fig. 1 is a structural representation of the present invention.
1, metal electrode, 2, the fusible alloy silk, 3, flux, 4, box body, 5, cover plate, 6, seal resin.
Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of Thermal Cutoffs of the present invention, comprise two metal electrodes that are arranged in parallel 1, fusible alloy silk 2 and airtight cavity, two metal electrodes, 1 one ends go deep in the airtight cavity, the metal electrode 1 that gos deep in the airtight cavity connects by fusible alloy silk 2, be coated with special resin on the fusible alloy silk 2, special resin is a flux 3, flux 3 is filled in the airtight cavity, fusible alloy silk 2 and be packaged in the airtight cavity with the connecting portion of two metal electrodes 1, airtight cavity comprises box body 4 and cover plate 5, and cover plate 5 is crowned for relative box body 4, and two metal electrodes 1 are drawn the outer and box body 4 wall contact positions of box body 4 and are coated with and seal resin 6.
The good airproof performance of airtight cavity seals resin 6 metal electrode 1 and the contact position of box body 4 walls is more merged, and simple in structure, manufacturing process is simple, saves cost.
Claims (3)
