Abstract
The invention relates to a thermal fuse body for a round headed contact wire, which comprises a metal case, temperature sensing particles, a front gasket, a drum-shaped spring, a back basket, a breaking electrode, a breaking spring, a porcelain bead, a riveting wire and a contact wire, wherein an end opening of the metal case at the connecting part of the contact wire and the porcelain bead is sealed by epoxy resin. The thermal fuse body is characterized in that the end head surface of the breaking electrode contacting the contact wire is a spherical surface. The thermal fuse body has the advantages that the contact effect of the contact wire and the breaking electrode can be improved, and the product quality is improved.
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 globular model contact line of sensible heat body.
Background technology
Thermal fuse-link is also referred to as Thermal Cutoffs, and 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, and 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 wherein the contact line is the important parts of fuse-link; It plays the effect of conducting electric current in product; The termination face that present contact line contacts with the disjunction electrode is the plane, the termination of contact line and disjunction electrode make contact to the right angle, when making mistakes in installation process; Will make contact line deflection; Cause the contact line to contact not exclusively thus, thereby increased the conducting resistance of product, finally influenced the quality of product with the disjunction electrode.
Summary of the invention
To above-mentioned shortcoming, the object of the invention is to provide a kind of can improve the contact line contacts effect and the globular model contact line that improves the quality of products with the disjunction electrode thermal fuse-link.
Technology contents of the present invention is: the thermal fuse-link of globular model contact line comprises 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 termination face that the contact line contacts with the disjunction electrode is a sphere.
The advantage that is compared with prior art had of the present invention is: after being sphere through the termination face that the contact line is contacted with the disjunction electrode; When the contact line little deviation occurs in installation process; Contact thread ball face and movable contact spring contact site do not have tangible change yet; Thereby can not influence performance of products, guarantee the quality of product to a greater extent.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation of contact line among the present invention.
Specific embodiment
The thermal fuse-link of a kind of globular model as depicted in figs. 1 and 2 contact line 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 the termination face 10.1 that contact line 10 contacts with disjunction electrode 6 is spheres.
