Protector, be one of using most common protection device.Fuse can be divided into plug-in with contact knife and circuit connecting mode
Fuse, coupling type fuse, whether there is or not be divided into filled fuse and non-filled fuse etc. for also with good grounds filler.It is generally main
Wanting structure includes shell, the melt of setting in the housing, positioned at the contact knife of hull outside connection melt.It is easily produced when disjunction voltage is high
When raw electric arc, arc-extinguishing medium can be filled in shell, when disjunction voltage is low, when being not likely to produce electric arc, then can not have to filling and go out
Arc medium.In general, multiple melts can be welded in a fuse.
In the type of fuse, there is a kind of fuse with blown fuse indicator, after fusing, indicator then can point
It is bright, fusing alarm is carried out, is repaired to facilitate.Fuse internal structure with indicator: in fuse inner walls
On be provided with a conductive constantan wire, after then bending the centre of constantan wire (constantan wire does not break, is only bending), so
Spring is set in bending place afterwards, the constantan wire bending part for being provided with spring is placed on the through-hole that fuse housing body shell wall opens up
In, the indicator for touching property is set again on spring.The both ends of constantan wire are located at the both ends of shell and connect with contact knife
It connects.Under unblown indicator not working condition, spring is in compressive state.After fusing, spring then pops up contact knife and refers to
Show device work alarm.
In process of production due to such fuse, the constantan wire of indicator will appear assembly during technique is realized and draw
Drag, the sand that shakes passively is worn, worn on tube body along cusped edge, and it is different to cause fuse indicator to occur in semi-finished product or finished product
Situations such as often pop-up, damage；Fuse in application process, normal fuse or the abrasion occurred in the fabrication process it
Afterwards, due to will appear in application environment expand with heat and contract with cold, Vibration Condition, and continue in such situation, the constantan of fuse indicator
Silk can be broken, and cause the instruction or damage extremely of fuse indicator will at this time if there is the microswitch of indicator linkage
There is false alarm, additional maintenance, inspection fee can be brought, it is serious to may cause situations such as equipment is out of service.
Summary of the invention
It can prevent fusing the technical problem to be solved by the utility model is to provide one kind and refer to non ageing fuse, work
Make high reliablity.In order to solve the above technical problems, technical solution provided by the utility model be it is a kind of prevent fusing instruction failure
Fuse, including fuse shell, and the indicator being arranged on shell, the indicator include being arranged in melt shell
The both ends of conductive filament on wall, the conductive filament are located at shell both ends；The open-work with extraneous conducting is offered on the housing,
The conductive filament bending is simultaneously provided with compressed spring in the conductive filament bending part, is provided with the conductive filament folding of the compressed spring
Crook is located in the open-work, is provided with warning indicator in the open-work above the compressed spring；It is arranged in the shell
The periphery of conductive filament on inner wall is arranged with insulating sleeve or insulating protective coating.
In shell both ends conductive filament by being set as arcwall face at the end edge at position.
The groove for penetrating through the shell both ends is provided in the open-work two sides, the both ends end face of the groove is set as arc
Shape face；The conductive filament for being provided with insulating sleeve or conductive filament with insulating protective coating are located in the groove.
No matter the fuse of the utility model there is friction, the upper and lower pulling, point of gravel in production, application process
The abnormal conditions such as other of the abrasion of rib or application process vibration, will not result in fuse indicator constantan wire and are not requiring
Indicator caused by fracture indicates extremely at position, can guarantee the fuse indicator only ability when fuse fuses
It is normally disconnected and is indicated.
Detailed description of the invention
Fig. 1, fuse schematic cross-sectional view.
Fig. 2 is arranged the conductive filament structural schematic diagram of insulating sleeve.
Specific embodiment
Scheme in view of the above technology is now lifted preferred embodiment and is specifically described in conjunction with diagram.Referring to Fig. 1 to Fig. 2,
In: fuse, including shell 1 are provided with melt, filled with arc-extinguishing medium in shell, shell both ends are provided with contact knife.?
Open-work is offered on the shell wall of shell, indicator 3 is installed in the indicator upper cover 2 above open-work, is pacified below indicator
Equipped with compressed spring 4.Through hole structure, and the compressed spring, conductive filament, the indicator structure that are arranged in open-work are the prior art,
It will not be described in detail here.Conductive filament 5, material are constantan.Its length direction for passing through shell is located in inner walls, conductive
It is located at the both ends of shell after the both ends difference bending of silk.Conductive filament is entwined and is being pressed in the through-hole position bending for being equipped with indicator
In contracting spring, compressed spring is made to be in compressive state.Not bending outside conductive filament positioned at inner walls is led being located at open-work two sides
It is arranged with insulating sleeve 6 week.By the protection of insulating sleeve, the intracorporal arc-extinguishing medium of shell that can avoid filling carries out conductive filament
Abrasion, abrasion or end edge cusped edge etc. caused by fuse shakes cause abrasion etc. to cause to be broken conductive filament.In order to avoid wearing,
One layer of insulating coating can also be coated in the periphery of conductive filament, for improving wear resistance.When insulating sleeve is set, it is located at shell
The conductive filament of body both ends endface is located at except insulating sleeve, make its can preferably with the contact knife conductive contact of fuse；When
When being provided with insulating coating on conductive filament, insulating coating is not set on the conductive filament for being located at shell both ends endface, makes it can be more
The good contact knife conductive contact with fuse.
In order to be worn conductive filament will not in shell, opened up in the inner walls of open-work two sides fluted
Penetrate through shell both ends.The both ends of groove, i.e. open-work one end and shell one end, are provided with arcwall face.It is arranged with insulating sleeve or painting
The conductive filament for being covered with insulating coating can be set in a groove, is not in that conductive filament distorts in shell, is extruded mobile
It happens.It is positioned by groove, reduces arc-extinguishing medium particle to the insulating sleeve of conductive filament or insulating coating
The contact surface of impact reduces abrasion.It is fixed after being bent due to the both ends of conductive filament at the both ends of shell, conductive filament is recessed
At the both ends arcwall face of slot when bending, arcwall face is smooth contact surface, abrasion will not be caused to cause conductive filament as cusped edge
It fractures.Groove is located at through-hole position one end and is also provided with arcwall face simultaneously, the conductive filament of open-work bending will not be because of cusped edge
It causes to wear and arrive and be broken.Working principle of the utility model is: conductive filament fuses in the bending part being located in open-work, then press
Contracting spring loses pressure, bounces up upwards, touches indicator, ejects indicator, indicator work alarm outward.
The shell structure of the utility model and conductive filament periphery are arranged insulating sleeve or coating insulating coating and can prevent from leading
For electrical filament because indicator caused by the extraneous factors such as abrasion are broken fails, the alarm for improving the fuse with indicator is reliable
Property.
