Fig. 1：The structure diagram of the prior art；
Fig. 2：The structure diagram of the utility model；
Fig. 3：The schematic diagram of the utility model warning device.
Specific embodiment
The utility model is described in detail below with reference to specific embodiment shown in the drawings.But these embodiment party
Formula is not limited to the utility model, structure that those of ordinary skill in the art are made according to these embodiments, method or
Conversion functionally is all contained in the scope of protection of the utility model.
As shown in Figure 1, the utility model discloses a kind of glass tube fuse, and including cartridge fuse 1, the cartridge fuse
1 is glass round tube, and can pass through glass using glass tube observes its internal state, such as whether there is breakage etc.；Certain fuse
Pipe 1 can also be ceramic material.The cartridge fuse 1 has the unsealed hollow cavity 2 of a two side ends, the hollow cavity
A fuse 3 is provided in body 2, preferred fuse 3 is made of the alloy wire of delicate in the utility model, certainly, also may be used
It is made of other materials, just no longer cross illustrates more in the utility model.3 shape of fuse is curve or straight line, and both ends are divided
Do not extend opposite to each other to the two side ends of the cartridge fuse 1, and fixed knot 4 is equipped on the both ends of the fuse 3.
Plastic heating curing is filled in the two side ends of the cartridge fuse 1 plastic end enclosure 5, just makes the hollow cavity 2
Seal cavity is formed, and the fixed knot 4 at least partly extends and is placed in the plastic end enclosure 5.Using plastic end enclosure to insurance
The both ends of fiber tube are sealed, and plastic end enclosure belongs to insulating part, without being surface-treated to it, are significantly reduced and are produced into
This expenditure.Meanwhile can be made into integration between lead and fuse and plastic end enclosure by filling plastic heating curing, reduce hand labor
Intensity.The plastic end enclosure 5 is placed in the cartridge fuse, i.e., the end face of described plastic end enclosure 5 is without departing from the fuse
The end face of pipe 1.The outer diameter of so entire fuse maximum is then the outer diameter of cartridge fuse 1, so that the outer diameter of the fuse
It greatly reduces.
The utility model further includes the lead 7 being arranged on outside the cartridge fuse 1, and the lead 7 at least partly extends
It is placed in the plastic part 5, and electric connection is generated after being riveted with the fixed knot 4.
In order to which preferably straight line insurance function, the technical solution of the utility model also have following improvement.
Warning device is additionally provided on the hollow cavity 2 of the cartridge fuse 1, the warning device includes an insulating stiff
Silk and a pressure-sensing conductive rubber silk 82, the mutually winding of the pressure-sensing conductive rubber silk 82, insulating stiff silk and fuse 3 are set
It puts, the pressure-sensing conductive rubber silk 82 is connected with the unit piece 83 and 87 circuit of ammeter being arranged on outside fuse, the unit
Piece 83 is connected with battery 84, switch 85,86 circuit of OLED lamps.
Further, it is arranged with high-temperature insulation sheath on the pressure-sensing conductive rubber silk 82.The pressure-sensing conductive rubber
Silk 82 is one kind in natural conductive rubber, butyronitrile conductive rubber, EPDM conductive rubber, the pressure-sensing conductive rubber silk 82
Characteristic be that resistance value declines when increased situation is under pressure on its surface.
The course of work of warning device in the utility model is simply illustrated below：Due to the pressure-sensing conductive rubber silk
82nd, insulating stiff silk and fuse 3 mutually winding is set, so the pressure-sensing conductive rubber silk 82, insulating stiff silk and molten
3 threes of silk mutually squeeze always.
In normal operation, the pressure that 82 surface of pressure-sensing conductive rubber silk is subject to is constant, so the pressure-sensitive
The resistance value of conductive rubber silk 82 is also at steady state, due to the pressure-sensing conductive rubber silk 82 and ammeter 87, unit piece
83 and battery 84 form circuit, the resistance value of the unit piece 83 is constantly under steady state, so on the ammeter 87
Electric current is in steady state.It is set at this point, the current value on the ammeter 87 is in the predetermined of unit piece 83 in value,
The unit piece 83 controls the switch 85 to disconnect, and the battery 84,85 and OLED of switch lamps 86 do not form circuit, the OLED
Lamp 86 extinguishes.
When breaking down state, the fuse 3 itself fusing, the pressure-sensing conductive rubber silk 82 and insulating stiff silk it
Between pressure reduce, the pressure that 82 surface of pressure-sensing conductive rubber silk is subject to also will reduce, so the pressure-sensing conductive rubber silk
82 resistance value will increase, since the pressure-sensing conductive rubber silk 82 and ammeter 87, unit piece 83 and battery 84 form circuit,
The resistance value of the unit piece 83 is constantly under steady state, so will increase electric current on the ammeter 87, at this point,
Current value on the ammeter 87 is not at the predetermined of unit piece 83 and sets in value, and the unit piece 83 controls the switch
85 are closed, and the battery 84,85 and OLED of switch lamps 86 form circuit, and the OLED lamps 86 shine, to achieve the purpose that warning.
Compared with the prior art the utility model has the following advantages that：
1st, the both ends of cartridge fuse are sealed using plastic end enclosure, plastic end enclosure belongs to insulating part, without to its into
Row surface treatment significantly reduces production cost expenditure；It meanwhile can be by filling plastics between lead and fuse and plastic end enclosure
It is heating and curing and is made into integration, reduce hand labor intensity；
2nd, plastic end enclosure is cured to through filling plastic heating on cartridge fuse, reduces the risk of damage, improves yields；Together
When, internal whether there is can be also observed by lucite pipe breakage；
3rd, the entire outer diameter of fuse is smaller than the prior art, has achieved the purpose that miniaturization；
4th, real-time monitoring to fuse can be achieved, when breaking down such as circuit, whether can be shone by fuse thus
