Abstract
The invention relates to a thermal fusing body capable of preventing loosening of a riveting line, which comprises a metal shell, temperature sensing particles, a front spacer, a rear spacer, a drum-shaped spring, a breaking electrode, a breaking spring, a porcelain bead, a riveting line and a contact line, wherein a connection hole is formed at one end of the metal shell. The thermal fusing body is characterized in that the connection hole of the metal shell is a square hole. The thermal fusing body provided by the invention has the advantages that the riveting line does not rotate in a process of processing, pinching, twisting and using the thermal fusing body, so that the loosening between the riveting line and the connection hole is avoided.
Description
Technical field
The present invention relates to a kind of thermal fuse-link, relate in particular to the loosening thermal fuse-link of the anti-rivet line of a kind of energy.
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, one end of metal shell has a wiring hole, wiring hole is circular, rivet line is riveted in the wiring hole, temperature-sensing particle, front pad, drum type spring, back pad, disjunction electrode, disjunction spring and porcelain bead once snugly fit in the metal shell, the contact line is connected with porcelain bead, and the metal shell port in contact line and porcelain bead junction seals with epoxy resin; Because rivet line is riveted in the circular wiring hole, rivet line is affectedly bashful in the use in the processing of thermal fuse-link, rivet line rotates because being affectedly bashful to twist to focus in the wiring hole easily, make and take place loosening between rivet line and the wiring hole and the generation gap, make the temperature-sensing particle of thermal fuse-link inside because of the ingress of air oxidation deterioration, thereby thermal fuse-link was lost efficacy.
Summary of the invention
At above shortcoming, the object of the present invention is to provide the loosening thermal fuse-link of the anti-rivet line of a kind of energy, it can make rivet line be affectedly bashful in the twisting use in the processing of thermal fuse-link and can not rotate, thus make can not produce between rivet line and the wiring hole loosening.
Technology contents of the present invention is: the loosening thermal fuse-link of the anti-rivet line of a kind of energy, comprise metal shell, temperature-sensing particle, front pad, back pad, drum type spring, disjunction electrode, disjunction spring, porcelain bead, rivet line and contact line, one end of metal shell has a wiring hole, rivet line is riveted in the wiring hole, temperature-sensing particle, front pad, drum type spring, back pad, disjunction electrode, disjunction spring and porcelain bead once snugly fit in the metal shell, the contact line is connected with porcelain bead, and the metal shell port in contact line and porcelain bead junction seals with epoxy resin; The wiring hole that it is characterized by described metal shell is square hole.
Compared with prior art, advantage of the present invention is: after rivet line is riveted in the wiring hole, the junction of rivet line and wiring hole is to be extruded the back to fill full wiring hole, the circular wiring hole of metal shell one end is replaced to the square hole wiring hole, thereby the junction of rivet line and wiring hole can not rotated, rivet line is affectedly bashful in the twisting use in the processing of thermal fuse-link can not rotate, thereby make can not produce between rivet line and the wiring hole loosening, prevent temperature-sensing particle ingress of air oxidation deterioration, guaranteed the electrical insulation properties that thermal fuse-link is good.
