Implant contacts with fuse, thus reduces weld tabs in the temperature of fuse contact position.
Preferably, described first connecting portion offers waist-shaped hole.
By technique scheme, owing to weld tabs is higher with the connection position heating of fuse, so ring can be made by waist-shaped hole
Oxygen implant contacts with fuse, thus reduces weld tabs in the temperature of fuse contact position.
Preferably, the opening part of described housing offers recess, the setting corresponding with pin of described recess.
By technique scheme, this capacitor is connected on circuit board by pin, so pin and the company of circuit board
Connect place's heating higher, therefore at this pin, offer recess, the flowing of heat can be facilitated, to play thermolysis.
Preferably, described draw-in groove includes the first groove and the second groove, and the width of described second groove is more than the width of the first groove, institute
Stating the width of the second connecting portion width more than the first connecting portion, when fuse is located in housing, the first connecting portion is sticked in the
In one groove, the second connecting portion is sticked in the second groove.
By technique scheme, this setting can make weld tabs in draw-in groove connect more stable so that fuse in
It is more stable, to improve the reliability of the present invention that housing connects.
Preferably, the shaft section of described rib is semicircular in shape.
By technique scheme, rib semicircular in shape so that rib is point cantact with the sidewall of fuse, so that core
Son is effectively isolated with housing.
