Embodiment
By describing technology contents of the present utility model, structural feature in detail, being realized object and effect, below in conjunction with execution mode and coordinate accompanying drawing to be explained in detail.
Fig. 1-Figure 4 shows that schematic diagram of the utility model integral type fuse the first embodiment.
Integral type fuse as depicted in figs. 1 and 2, comprises insulation shell 100, melt 200 and screen 300.One side direction sunken inside of insulation shell 100 forms containing cavity 110, all side seals of containing cavity 110 is closed, upper opening only; Melt 200 comprises fusing portion 210, the first conducting end 220 and the second conducting end 230, fusing portion 210 is arranged in containing cavity 110, the two ends of fusing portion 210 are connected to the first conducting end 220 and the second conducting end 230, the first conducting end 220 and the second conducting end 230 and stretch out containing cavity 110; Screen 300 is arranged in containing cavity 110 with shielding fusing portion 210.Shown in Fig. 3 and Fig. 4, more specifically:
As shown in Figure 3, the bottom of containing cavity 110 and sidewall sealing, only open top.Melt 200 comprises fusing portion 210, the first conducting end 220, the second conducting end 230 and two elastic part 240.One end of two elastic part 240 is connected to fusing portion 210; The other end of two elastic part 240 is connected to the first conducting end 220 and the second conducting end 230.Wherein, fusing portion 210 and two elastic part 240 are arranged in containing cavity 110, and the first conducting end 220 and the second conducting end 230 are stretched out containing cavity 110 and to the both sides outer wall bending of insulation shell 100 along the inwall of containing cavity 110; The first conducting end 220 and the second conducting end 230 are to the setting of the both sides outer wall bending of insulation shell 100, can locate the relative position of melt 200 and insulation shell 100 on the one hand, fusing portion 210 and two elastic part 240 are suspended in containing cavity 110, on the other hand, when integral type fuse is connected in circuit, the first conducting end 220 and the second conducting end 230 that extend out to insulation shell 100 both sides outer walls can be electrically connected to external circuit easily.
Melt 200 conventionally in energising direction, arrange an intensity weak, be heated and excessively can melt disconnected fusing position (in the present embodiment, being fusing portion 210), when melt 200 is heated while there is deformation, fusing portion 210 forms the weak location that melt 200 is disconnected; The integral type fuse that the utility model provides, the strain direction of elastic part 240 is consistent with the energising direction of integral type fuse, the deformational stress being subject to reduce weak fusing portion 210, thus reduce the possibility that melt 200 disconnects.In the present embodiment, fusing portion 210 is arranged between two elastic part 240, the elastic part 240 absorption deformational stresses by both sides, reduce the stressed of fusing portion 210, thereby reduce the possibility that fracture occurs under deformational stress effect in fusing portion 210.Preferably, elastic part 240 is wavy or S shape, and elastic part 240 can also be other elastic constructions certainly.
Further, insulation shell 100 also have accommodating elastic part 210 and for elastic part 210, there are strains dodge chamber 112.Concrete, referring to shown in Fig. 3, the bottom of containing cavity 110 upwards protrudes out and forms locating convex block 120.The position of locating convex block 120 is incorporated by reference to shown in Fig. 4: locating convex block 120 has four, the both sides that are arranged at containing cavity 110 of four locating convex block 120 symmetries; Locating convex block 120 outwards protrudes out formation from the bottom of containing cavity 110 and the junction of sidewall.Further, locating convex block 120 can also be formed to protruding out in containing cavity 110 by the sidewall of containing cavity 110.In the present embodiment, locating convex block 120 is cube structure, but not as limit, in being different from other embodiment of the present embodiment, locating convex block 120 can also be cylinder, round table-like or other structures.The structure of melt 200 and insulation shell 100 is as shown in Figure 2: the first conducting end 220 and the second conducting end 230 fasten respectively in the two side of containing cavity 110, fusing portion 210 and elastic part 240 are suspended in containing cavity 110, fusing portion 210 and elastic part 240 are between four locating convex blocks 120, and the position of fusing portion 210 and elastic part 240 is lower than the upper end of locating convex block 120.Locating convex block 120 tops are provided with cover plate 310; The setting of locating convex block 120 and cover plate 310, what containing cavity 110 was divided into the packing cavity 111 of cover plate 310 upsides and cover plate 310 downsides dodges chamber 112, wherein, the cavity that packing cavity 111 is the upper opening that surrounded by cover plate 310 and containing cavity 110 sidewalls, dodges the cavity that is roughly sealing that chamber 112 surrounds for bottom and sidewall by cover plate 310 and containing cavity 110.
In one embodiment, the binding agent of filling bonding cover plate 310 and containing cavity 110 in upside and/or all sides of cover plate 310, makes cover plate 310 be connected in insulation shell 100.In this embodiment, cover plate 310 is insulation material, the screen of cover plate 310 formation the utility model integral type fuses.In another embodiment, as shown in Figure 2, in the interior filling shielding of packing cavity 111 medium, form the screen 300 of the utility model integral type fuse.
At the utility model integral type fuse the second embodiment as shown in Figure 5, the first embodiment is identical with the utility model integral type fuse: comprise insulation shell 100 ' and melt 200 ', one side direction sunken inside of insulation shell 100 forms containing cavity 110 ', all side seals of containing cavity 110 ' is closed, upper opening only; Melt 200 ' comprises fusing portion 210 ', the first conducting end 220 ' and the second conducting end 230 ', fusing portion 210 ' is arranged in containing cavity 110 ', the two ends of fusing portion 210 ' are connected to the first conducting end 220 ' and second conducting end the 230 ', the first conducting end 220 ' and the second conducting end 230 ' and stretch out containing cavity 110 '.The first embodiment is different from the utility model integral type fuse: melt 200 ' does not comprise elastic part, make the melt 200 ' of the utility model integral type fuse the second embodiment not there is elasticity, accordingly, chamber is also dodged without setting in containing cavity 110 ' inside, that is, containing cavity 110 ' does not have locating convex block and cover plate; Directly in containing cavity 110 ', fill shielding medium and form screen 300 '.
Compared with prior art, the integral type fuse that the utility model provides, a side direction sunken inside in insulation shell 100 forms containing cavity 110, make containing cavity 110 only in a side opening of insulation shell 100, it is convenient on the one hand packs melt 200 in containing cavity 110 into and positions, and conveniently on the other hand to being positioned at the melt 200 of containing cavity 110, shields; Fusing portion 210, the first conducting end 220 and the second conducting end 230 are connected, and the first conducting end 210 is stretched out containing cavity 110 to be connected outside power supply with the second conducting end 220, structure and production technology that it simplifies integral type fuse on the one hand, reduce the possibility of integral type fuse loose contact on the other hand.The integral type fuse providing according to the utility model, its simple in structure, stable performance, production cost and use cost are lower.
Above disclosed is only preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belongs to the scope that the utility model is contained.
