Abstract
The invention relates to a heat-fusing body, comprising a metal shell, temperature-sensitive particles, a front gasket, a rear gasket, drum-shaped springs, a breaking electrode, breaking springs, porcelain beads, a riveting line and a contact line, wherein a port of the metal shell at the connecting position of the contact line and the porcelain beads is sealed by epoxy resin. The heat-fusing body is characterized in that the two ends of each porcelain bead are respectively provided with a convex head. The heat-fusing body has the advantages that the electric insulativity of a finished product can be improved, the used amount of epoxy resin is reduced and the collapse does not easily occur because the port is sealed by the epoxy resin.
Description
Technical field
The present invention relates to a kind of thermal fuse-link, relate in particular to a kind of with the thermal fuse-link of temperature-sensing particle as the sensible heat body.
Background technology
Thermal fuse-link is also referred to as Thermal Cutoffs; It comprises metal shell, temperature-sensing particle, front pad, back pad, drum type spring, disjunction electrode, disjunction spring, porcelain bead, rivet line and contact line; Rivet line is riveted on metal shell one end; Temperature-sensing particle, pad, drum type spring, back pad, disjunction electrode, disjunction spring and porcelain bead snugly fit into metal shell successively then, and the contact line is connected with porcelain bead, and the metal shell port of line and porcelain bead junction seals with epoxy resin in the contact; Because present porcelain bead is that an end has a plush copper, the other end is the plane; Because the profile that epoxy resin seals is for conical; And the termination on porcelain bead plane when being installed in the metal shell makes content of epoxy resin bigger outside metal shell, and epoxy resin seals and is prone to that collapse phenomenon is arranged; Influence product appearance, make that also the electric insulating quality of thermal fuse-link is not fine simultaneously.
Summary of the invention
To above-mentioned shortcoming, the object of the invention is to provide a kind of can improve the finished product electric insulating quality, reduce content of epoxy resin and epoxy resin seals the thermal fuse-link that is difficult for having collapse phenomenon.
Technology contents of the present invention is: thermal fuse-link comprises metal shell, temperature-sensing particle, front pad, back pad, drum type spring, disjunction electrode, disjunction spring, porcelain bead, rivet line and contact line; The metal shell port of line and porcelain bead junction seals with epoxy resin in the contact; It is characterized in that the porcelain bead two ends have a plush copper respectively.
The advantage that is compared with prior art had of the present invention is: through the porcelain bead two ends one plush copper is arranged respectively; Can reduce content of epoxy resin and epoxy resin thus and seal and be difficult for that collapse phenomenon is arranged, simultaneously thermal fuse-link improved greatly at the electric insulating quality of this port.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation of porcelain bead among the present invention.
Specific embodiment
A kind of thermal fuse-link as depicted in figs. 1 and 2 comprises metal shell 1, temperature-sensing particle 2, front pad 3, drum type spring 4, back pad 5, disjunction electrode 6, disjunction spring 7, porcelain bead 8, rivet line 9 and contact line 10; Metal shell 1 port of line 10 and porcelain bead 8 junctions seals with epoxy resin 11 in the contact; It is characterized in that porcelain bead 8 two ends have a plush copper 8.1 respectively.
