In conjunction with Figure 10, Figure 11, Figure 12, Figure 13, Figure 14 and Figure 16, corresponding with two insertion sections 230 of Insurance Block 200, electrical appliance kit body 300 both sides are provided with slot 310, and have the first boss 311 and the second boss 312 in slot 310.With a secondary insertion section 240 of Insurance Block 200 to corresponding, electrical appliance kit body 300 is also provided with secondary slot 320, in secondary slot, is provided with positive stop strip 321.
More high-visible in conjunction with Figure 14 and Figure 15, the first boss 311 in slot 310 and the second boss 312 are halfpace.The first surface 3111 down of the first boss 311 is inclined-plane, namely first surface 3111 and horizontal plane and vertical plane all not parallel, and second face 3112 towards slot 310 inside of the first boss 311 is plane, and namely the second face 3112 is a perpendicular.The 3rd face 3121 down of the second boss 312 is plane, and namely the 3rd face 3121 is a horizontal plane, and the fourth face 3122 upward of the second boss 312 is inclined-plane, namely fourth face 3122 and horizontal plane and vertical plane all not parallel.
In conjunction with Figure 16, Figure 18 to Figure 20, fuse 100 is installed to after on Insurance Block 200, the insertion section 230 of Insurance Block 200 is inserted in the slot 310 of electrical appliance kit body 300, the secondary insertion section 240 of Insurance Block 200 is inserted in the secondary slot 320 of electrical appliance kit body 300, and the second boss 312 of electrical appliance kit body 300 is positioned at the chute 234 of Insurance Block 200.
Under the operating state shown in Figure 18 and Figure 19, namely under the state that the pin 110 of fuse 100 contacts with the metal terminal 400 in electrical appliance kit body 300, now circuit turn-on, the first boss 311 in slot 310 is fastened togather with the projection 231 of insertion section 230, the first surface 3111 of the first boss 311 limits Insurance Block 200 and moves upward, second boss 312 does not contact with the lower end 232 of chute 234 simultaneously, but keeps certain distance.In this case, fuse 100 is not only subject to the clamping force of electrical appliance kit body 300, and due to the position-limiting action of first surface 3111 pairs of Insurance Blocks 200 and the clamping action of fuse installation portion 210 pairs of fuses 100, even if make fuse 100 in dither situation still be not easy.Meanwhile, coordinating of secondary insertion section 240 and secondary slot 320 can fixing reliable, firm of guarantee insurance seat 200.Groove 242 below secondary insertion section 240 coordinate with the positive stop strip 321 in secondary slot 320 can guarantee insurance seat 200 location more accurately and reliably.
Operating personnel enter non operating state as shown in figure 20 when running into obvious jam after pinching and clamping part 220 pulling out Insurance Block 200, the i.e. state that departs from the metal terminal 400 in electrical appliance kit body 300 of the pin 110 of fuse 100, in this case, second face 3112 of the first boss 311 in slot 310 extrudes the projection 231 of insertion section 230, insertion section 230 is made to produce towards the deformation of chute 234 inside, the first boss 311 pairs of insertion sections 230 are made to produce certain chucking power, guarantee that Insurance Block 200 can not fall voluntarily but remain on non operating state, second boss 312 contacts with the lower end 232 of chute 234 simultaneously, restriction Insurance Block 200 deviates from electrical appliance kit body 300 further.In other words, in a non-operative state, Insurance Block 200 and electrical appliance kit body 300 are in a kind of half released state.Those skilled in the art are to be understood that, for dissimilar fuse 100, from the operating state of such as Figure 15 to the non operating state of such as Figure 16, really the contact with the metal terminal 400 in electrical appliance kit body 300 is departed from order to ensure fuse 100, the extraction distance of Insurance Block 200 should be different, namely should consider in the design phase requirement that the relative displacement distance of the second boss 312 in chute 234 meets fuse 100 and depart from metal terminal 400 dimensionally.Like this, operating personnel pull out Insurance Block 200 until feel obvious jam time, namely mean that the metal terminal 400 of fuse 100 really and in electrical appliance kit body 300 departs from, circuit disconnects, and operating personnel can carry out maintenance work relievedly and can not there is the risk that hot line job causes personal injury.And, upper pull out Insurance Block 200 after, fuse 100 is still positioned at fuse installation portion 210, can not there is loss and later stage by mistake dress problem.Pull out in process upper, because first surface 3111 is inclined-plane, therefore operating personnel easily on pull out, simultaneously because fourth face 3122 is plane, therefore operating personnel are not easy Insurance Block 200 to extract in electrical appliance kit body 300 completely, and this just takes into account convenience and the difficult drop-off of State Transferring.
Preferred electrical appliance kit body 300 and Insurance Block 200 are designed to satisfied following condition: under operating state as shown in figure 19 electrical appliance kit body 300 metal terminal 400 pairs of Insurance Blocks 200 in the clamping force of fuse 100 of installing, be greater than the clamping force of fuse installation portion 210 pairs of fuses 100 of Insurance Block 200.This can by controlling distance between the size of installing hole 211, metal terminal 400, to the material of Insurance Block 200 and metal terminal 400 material be selected, adopt the various ways such as spring and shell fragment 420 to realize, and is only described for shell fragment 420 herein.The advantage done like this is: when pressing down Insurance Block 200, the degree of difficulty that degree of difficulty fuse 100 being contacted due to the clamping force that will overcome electrical appliance kit body 300 pairs of fuses 100 with metal terminal 400 is deviate from fuse installation portion 210 than fuse 100 is large, when therefore pressing down merely Insurance Block 200 under non operating state as shown in figure 20, although Insurance Block 200 is pressed down the operating state entered as shown in figure 19, but fuse 100 automatically can be deviate from Insurance Block 200, can not contact with the metal terminal 400 in electrical appliance kit body 300, in fact now circuit remains disconnection.Only have operating personnel to press down the fuse 100 of Insurance Block 200 and inside thereof simultaneously, fuse 100 just can be forced to contact with metal terminal 400.Doing so avoids misoperation and personal injury is brought to operating personnel, fail safe is high, simultaneously when fuse 100 changed by needs, operating personnel only need on the offensive pinching on clamping part 220 to pull out Insurance Block 200, and then press down merely Insurance Block 200, fuse 100 will be deviate from automatically, need not use specific purpose tool, easy accessibility.
Consider that operating personnel exist the risk that health or instrument contact Insurance Block 200 by mistake when operating, the upper end of the clamping part 220 in the present embodiment is higher than the upper surface of fuse installation portion 210, just defines a headspace like this between clamping part 220.First operating personnel can press down clamping part 220 when health or instrument contact Insurance Block 200 by mistake and be not easy to be pressed onto fuse 100, and the headspace between clamping part 220 provides space for fuse 100, therefore Insurance Block 200 be pressed down enter operating state after fuse 100 can deviate in the space between clamping part 220, this prevents misoperation to bring the risk of personal injury to operating personnel further, improves fail safe.
