Abstract
The invention relates to a thermal fusing body of a metal-shell small-angle shell nosing. The thermal fusing body comprises: a metal shell, a temperature-sensitive particle, a front pad, a drum type spring, a rear pad, a breaking electrode, a breaking spring, a porcelain bead, a riveting wire and a contact wire. A metal shell port located on a joint of the contact wire and the porcelain bead is sealed by epoxy resin. The thermal fusing body is characterized in that: the shell nosing of the metal shell is bended inwards and an angle alpha is 43-47DEG. By using the thermal fusing body of the invention, stability of a product with the shell nosing can be guaranteed. Springback of a component in the product can be prevented and quality of the product can be ensured.
Description
Technical field
The present invention relates to a kind of thermal fuse-link, relate in particular to the thermal fuse-link that a kind of metal shell low-angle closes up.
Background technology
Thermal fuse-link is also referred to as Thermal Cutoffs; It comprises metal shell, temperature-sensing particle, front pad, drum type spring, back pad, disjunction electrode, disjunction spring, porcelain bead, rivet line and contact line; Rivet line is riveted on metal shell one end; Temperature-sensing particle, front pad, drum type spring, back pad, disjunction electrode, disjunction spring and porcelain bead snugly fit into metal shell successively then; Porcelain bead is sleeved on an end of contact line, and the metal shell port of line and porcelain bead junction seals with epoxy resin in the contact, and the metal shell port before sealing with epoxy resin will inwardly close up; And the angle that the metal current shell closes up is 60 °; Because producing the common process of fuse-link product is labour-intensive machining state, the quality of product can influence the quality (it is not in place to close up) of closing in because of the size of dynamics because artificial reason receives certain influence when operation is closed up when employee's fatigue state; Also will seal with epoxy resin later because close up, be 48 hours the curing time of epoxy resin; The elasticity that metallicity because of shell oneself not in place is added the product contained spring if close up is easy to cause porcelain bead to eject, and influences the quality of product.
Summary of the invention
To above-mentioned shortcoming, the object of the invention be to provide a kind of back product that can guarantee to close up stability, prevent the resilience of product inner components and guarantee the thermal fuse-link that the metal shell low-angle of the quality of product closes up.
Technology contents of the present invention is: the thermal fuse-link that the metal shell low-angle closes up; Comprise metal shell, temperature-sensing particle, front pad, drum type spring, back pad, 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 angle [alpha] that the closing in of metal shell bends inwards is 43～47 °.
The advantage that is compared with prior art had of the present invention is: through reducing the closing in angle of metal shell, the stability after can effectively guaranteeing to close up prevents the resilience of product inner components, guarantees the quality of product.

Specific embodiment
The thermal fuse-link that a kind of metal shell low-angle as depicted in figs. 1 and 2 closes up; Comprise 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 the angle [alpha] that the closing in 1.1 of metal shell 1 bends inwards is 45 °.
