Description
Technical field
The utility model relates to the fuse technical field, is specifically related to the supper-fast fuse of a kind of used for electric vehicle direct current.
Background technology
Relying on power-actuated electric automobile is a kind of new energy source machine motor vehicle that is rising in the current whole world, be divided into mixed motivity type (PHEV) the three major types type of pure power type (EV), oil electric mixed dynamic type (HEV) and outer plug-in again according to structural principle, generally use lithium ion or lithium polymer storage battery to do the deposit and the output of electric power energy.And replenishing of electric energy relies on vehicle self or outside isolated plant is done the charging input, so the power accumulator of electric automobile and charger device just constitute the continuous ability and drive the important key device of horsepower of speeding of vehicle.
Because electric automobile mainly relies on driven by power, the operating voltage of its electrical system is up to hundreds of volt (Volt), and electric current if cross the short trouble of vehicle-mounted electrical system, will cause the major accident of car crash to take place up to hundreds of ampere (Amp).For this reason; standard GB/T 18384.2-2001 is in " electric automobile safety requirements " part 2; clearly stipulate in functional safety and the emergency protection the 5.5th " overcurrent cutting-off device ": " when electric current is excessive, should use a circuit brake, shearing device or fuse to disconnect at least one electrode of vehicle power (for example power accumulator) ".In " mixed power electric car safety requirements " GB/T 19751-2005 4.1.1.5 bar, clearly stipulate again: " power accumulator and motor circuit system should protect by circuit breaker and fuse; this device should be able to the connecting circuit of automatic disconnection and power accumulator occur under the situation of short circuit at the overcurrent of Railway Car Plant's regulation, the circuit that is connected with power accumulator ".
In sum; no matter the electric automobile of which kind of vehicle type structure and type of drive; must there be a Vehicular accumulator cell and an electric energy storage and the power-jdriven gear that main motor constitutes in its inside; fuse just is installed in the middle of this two bigger device, takes very important direct current passage and two-way short-circuit protection function.During vehicle charging, fuse is done failure monitoring protection to the electric current of input storage battery, prevents that overload that circuit occurs or short circuit current are to the storage battery damage that impacts; When battery discharging is worked, fuse is implemented the backward supervision protection to main motor and inverter, overload that the prevention electric system produces or short circuit current return scurries storage battery, prevents simultaneously that also the short circuit current that electrical system occurs from damaging charger and motor.
Existing industrial use comprises outer tube, arc extinguishing thing layer, melt core and conducting terminal with the fuse that can be used for electric automobile; but the problem of its existence is: the version that outer tube is connected with conducting terminal employing screw or real core circle Xiao Ding; fuse jolts under the effect of impact impulsive contact force of vibrations standing running car; the straight pin of screw or real core is understood loose or dislocation and is caused fuse to disintegrate; do not have protective effect and also will cause a serious accident, therefore be not suitable on automobile, using.
Summary of the invention
The utility model will provide a kind of used for electric vehicle direct current supper-fast fuse, to overcome the problem that is not suitable for using that prior art exists on automobile.
In order to overcome the problem that prior art exists, the technical solution of the utility model is: the supper-fast fuse of a kind of used for electric vehicle direct current, comprise conducting terminal, outer tube, arc extinguishing thing layer and melt core, its special character is: connect by uniform hollow elastic cylindrical pin between described conducting terminal and the outer tube.
Be equipped with blown fuse indicator in the conducting terminal of an above-mentioned end, the tension seal wire of blown fuse indicator is connected with the conducting terminal of the other end.Seal wire fuses simultaneously when the melt core fuses, and discharges blown fuse indicator and ejects conducting terminal, shows that this fuse has been in complete off-state.
Also be provided with the elasticity display piece in the middle of the above-mentioned outer tube, the tension seal wire of elasticity display piece is connected with the conducting terminal at the inner two ends of outer tube respectively.Its operating principle is identical with blown fuse indicator, but the position difference that fusing shows.
Compared with prior art, the utility model has the advantages that:
1, the hollow elastic cylindrical pin that rolls with spring steel plate passes through the tensioner effect of self, conducting terminal and outer tube are firmly connected into the hard and soft integral body that combines that to disassemble, bear for a long time and absorb the jolt impact of vibrations of running car and collide external force, do not cause the fuse disintegration to be broken and can not come off voluntarily,, have more the opposing outside destroy and prevent the security reliability that gets loose and disintegrate with the prior art version that screw or real core straight pin are connected than the outer tube of industrial fuse and conducting terminal;
2, be provided with a blown fuse indicator and elasticity display piece respectively at the conducting terminal and the outer tube middle part of fuse, be convenient in time check the blown state of finding fuse.When the fuse operate as normal, they all are in the indentation state, when the melt core transshipped or short circuit current fusing after, the seal wire of tension blown fuse indicator and elasticity display piece blows immediately, blown fuse indicator and elasticity display piece all are the ejection state, eye-catching this fuse of color-coded prompting disconnects, and need do timely replacing.
3, the utility model can be widely used in the new-energy automobile parts technical field of automobile industry, specifically can be applicable to also can be applicable in the low voltage component of optical, mechanical and electronic integration class in electric powered motor storage battery and the charger system.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Description of reference numerals is as follows:
1-conducting terminal, the hollow elastic cylindrical pin of 2-, 3-outer tube, 4-arc extinguishing thing layer, 5-melt core, 6-blown fuse indicator, the 7-display piece that fuses.
Embodiment
Below in conjunction with accompanying drawing the present invention is described in detail.
Referring to Fig. 1, the supper-fast fuse of a kind of used for electric vehicle direct current comprises conducting terminal 1, outer tube 3, arc extinguishing thing layer 4 and melt core 5.Connect by uniform hollow elastic cylindrical pin 2 between said conducting terminal 1 and the outer tube 3.Be equipped with blown fuse indicator 6 in the conducting terminal 1 of one end, the seal wire of tension blown fuse indicator 6 is connected with the conducting terminal of the other end; Also be provided with elasticity display piece 7 in the middle of outer tube 3, the seal wire of tension elasticity display piece 7 is connected with the conducting terminal 1 at outer tube 3 inner two ends respectively.
Under the user mode, fuse is the excellence conductor of conduction current when normal power-up is worked, and when being short-circuited electric current, melt core 5 disconnects at extremely short instant melting, reaches the isolation features of automatic disengagement failure.Arc extinguishing thing layer 4 plays the effect that forces arc extinction in fusing process, blown fuse indicator 6 ejects automatically in melt core 5 fusing backs, and elasticity display piece 7 is action simultaneously also, shows that fuse has been in the state that cut-offs fully.
