Description
Technical field
This utility model relates to fuse technologies field, particularly relates to the fuse that a kind of enclosing cover improves.
Background technology
Fuse refers to when electric current exceedes setting, makes melt fuse with the heat that itself produces, and a kind of electrical equipment of disconnecting circuit, fuse is also known as electric fuse.Fuse is after exceeding setting a period of time according to electric current, makes Melt molten with the heat that himself produces, so that circuit disconnects；Use a kind of circuit brake that this principle is made.Fuse is widely used in high and low voltage electric distribution system and control system and electrical equipment, as the protector of short circuit and overcurrent, is apply one of most common protector.In prior art, the connection owing to connecting terminal and enclosing cover is generally adopted riveting method, so causes occurring in the inner side of enclosing cover a projection thus adding the resistance of contact gap and contact position, have impact on electric conductivity.
Summary of the invention
This utility model provides the fuse that a kind of enclosing cover improves, it is provided that a kind of smooth way of contact so that fuse has better electric conductivity.
In order to solve above-mentioned technical problem, technical solution adopted in the utility model is:
The fuse that a kind of enclosing cover improves, including fuse, described fuse includes body, connects terminal；The two ends of described body being provided with enclosing cover, described outer covering is provided with through hole, is fixedly connected with contiguous block on described through hole, described connection terminal connects described contiguous block.
Further, through hole described in described contiguous block tight fit connection.
Preferably, the quantity of described through hole is two, and described connection terminals fuse connects described contiguous block.
Further, covering outside described, the edge of described through hole is provided with concave station, is provided with stator on described contiguous block, and described stator is fixed on described concave station；Described connection terminals fuse connects the described enclosing cover of described stator and stator periphery.
Further, between described body and described enclosing cover, it is provided with inner cap, described enclosing cover both sides are provided with card convex, cover in described and be provided with the groove mated with described card convex.
Preferably, in described body, it is filled with arc quenching material.
Preferably, described arc quenching material is quartz sand.
Preferably, described body is epoxy resin body or pottery body.
Preferably, described connection terminal is copper tip, the silver-plated terminal of copper or copper nickel plating terminal.
Preferably, outside described body, it is coated with explosion-proof layer.
This utility model provides the fuse that a kind of enclosing cover improves, and described outer covering is provided with through hole, is fixedly connected with contiguous block on described through hole, and described connection terminal connects described contiguous block；So that contact position seamlessly transits, decrease contact resistance, improve the electric property of fuse.
