Description
Technical field
The utility model relates to fuse technical fields, and in particular, to a kind of high breaking ceramics fuse.
Background technique
The effect of fuse is constantly increased along with electric current, and raised electricity when circuit malfunctions or exception
Stream is possible to certain important devices in damage circuit, it is also possible to burn circuit or even cause fire.If in circuit correctly
Fuse is disposed, then fuse will be when current anomaly be increased to certain height and temperature, itself fusing is cut
Power-off stream, to play the role of protecting circuit safety operation.When being that fuse is powered, made by the heat that electric energy is converted fusible
The temperature of body rises.When running current or the overload current of permission pass through, the heat of generation by fusable links, outer housing to
Ambient radiation progressivelyes reach balance by modes, the heats of the heat and generation that distribute such as convection current conduction.If generated
Heat is greater than the heat distributed, and extra heat is just gradually accumulated in fusable links, increase fusible temperature, when temperature reaches
When with being more than the fusing point of fusable links, fusable links will be made to melt, fusing and cut off electric current, playing the work of safety protective circuit
With.
Currently, the construction of fuse is by both ends lead containing chapeau de fer, glass tube or ceramic tube, fuse, ring currently on the market
Oxygen resin composition, needs to be welded with scolding tin between fuse and chapeau de fer, is that fuse can firmly be connect with chapeau de fer and lead.By
In there are scolding tin, the cost of manufacture is not only increased, and its manufacturing process is increasingly complex；Since there may be the feelings of rosin joint
Condition causes the rejection rate of fuse to improve；When fuse works, the calorific value at scolding tin position is bigger, and energy dissipation is more, unfavorable
In environmental protection.
As Patent Office of the People's Republic of China discloses the practical new of " a kind of high-breaking ultra-small porcelain tube fuse " on June 9th, 2010
The notification number of type patent, the patent is CN201717219U, specifically discloses a kind of high-breaking ultra-small porcelain tube fuse, including
Porcelain tube, set on the chapeau de fer at porcelain tube both ends, the lead being connect with chapeau de fer, the fuse in porcelain tube；The chapeau de fer includes end cap, side
It encloses, protrusion is provided inwardly on the side wall, be equipped with recess on the porcelain tube at respective protrusions, the recess is matched with the protrusion
It closes, the fuse end is set between the protrusion and the recess.It can be with while guaranteeing the contact of chapeau de fer and fuse
Fully phase out scolding tin.Although above-mentioned high-breaking ultra-small porcelain tube fuse solves above-mentioned technical problem, still, porcelain tube insurance
The fuse of silk is that linear design is mounted in fuse, has even been vaporized because blown fuse fuse has melted (fusing), but
It is electric current there is no cutting off, reason is exactly two electrodes of fuse in fusing in a flash under the action of voltage and current
Between phenomenon of arc discharge occurs so that the fuse at both ends is spaced a distance rear fuse and could disconnect, such fuse encounters
When high current fuses, fuse is caused not have because high voltage can make fuse generate long-time arcing after the fuse failure of straight line setting
There is disconnection, only after fuse burning a period of time, the long fuse of fuse spacing distance at fuse both ends is just disconnected, between
Fuse burning generates a large amount of heat；Therefore, the fuse of linear design fuse does not have the ability of fast arc extinction, causes
A large amount of heat is generated inside fuse causes fuse to burn, and the service life of fuse is low.
Therefore, a kind of high breaking ceramics fuse need to be provided, so as to solve the deficiencies in the prior art.
Utility model content
In order to overcome the deficiencies of the prior art, the utility model provides a kind of high breaking ceramics fuse, using insurance
The curve shape fuse of silk can quickly block electric arc, the heat inside fuse be reduced, to guarantee that fuse will not be burnt
It ruins, improves the service life of fuse.
The technical solution of the utility model is as follows:
A kind of high breaking ceramics fuse, including ceramic tube body and be arranged in the ceramic tube body both ends end cap and
The fuse of the ceramic tubular body is inside set；The inner wall of the end cap and the outside wall surface of the ceramic tube body are mutually sticked
It sets；The ceramics tube body includes solid tube body and hollow body, and the solid tube body has protruded out number toward the hollow body direction
Block barrier blocks；The fuse is in buckling curve shape, is arranged in the hollow body in the fuse.
Preferably, the fuse is in curved saw-toothed shape, and the fuse is from one end of the hollow body along institute
Barrier blocks setting is stated to be connected on the hollow body of the other end.
Preferably, the barrier blocks triangular shape.
Preferably, the upper end of the solid inboard wall of tube body has protruded out two pieces of barrier blocks down, in the solid tubes body
The lower end of wall has up protruded out three pieces of barrier blocks, the alternate setting of the barrier blocks of five pieces on the solid tube body.
Preferably, the both ends of the ceramic tube body are provided with scolding tin, and the both ends of the hollow body are arranged in the scolding tin
On inner wall.
Preferably, the end cap is equipped with lead, and the lead and the end cap are in integral structure.
Further, the end cap is copper cap.
The utility model has the following beneficial effects: compared with prior art, the structure design of the high breaking ceramics fuse is new
Grain husk, using curve shape fuse failure when, the spacing of the fuse separation at ceramic tube body both ends is than very fast, so that the fuse go
ETAD expected time of arrival and departure is short, obstructs the electric arc that fuse burning generates when fuse disconnects by the several piece barrier blocks on ceramic tube body, can be fast
The blocking electric arc of speed, the generation for reducing fuse internal heat improve the use of fuse to guarantee that fuse will not be burnt
Service life also effectively improves the arc extinguishing ability of fuse fuse, reduces the explosive force of fuse.
