Description
[technical field]
The utility model relates to a kind of automobile fuse, refers in particular to a kind of automobile fuse with the fusing indication.
[background technology]
Automobile fuse in the past; all only carry out the overcurrent fuse protection in the automobile use; and fuse conducting whether situation can't directly show in it, just need pull up strip fuse piecewise to find out whether fuse is intact in it when doing inspection, and efficient is very low.The someone has released the fuse box that has demonstration for this reason, but the demonstration of the type is all at safety box, its versatility and configurability are all not good, and the purpose of its product part in order to realize significantly showing, its extra display circuit complexity of adding, the result causes whole fuse box volume very big, though another part volume is less, but display circuit has the access polar requirement in it, cause especially to note when mounted the correspondence problem of its fuse box polarity thus, will cause it can't effectively bring into play the function that the fusing back shows in case dress is wrong, delay vehicle and obtain effectively maintenance.
[summary of the invention]
The purpose of this utility model is to have overcome above-mentioned defective, but the fusing indicator type automobile fuse of the small and exquisite and self adaptation insurance circuit polarity rational in infrastructure of a kind of volume is provided.
The purpose of this utility model is achieved in that a kind of automobile fuse with the fusing indication, it includes housing, be plugged with left and right sides electrode in the housing, be electrically connected by a fusible conductor between the electrode of the left and right sides, its improvements are: also be in series with luminescence unit between the electrode of the described left and right sides, described luminescence unit is by pcb board and resistance is set in last series connection and the LED lamp constitutes;
A described left and right sides electrode side in opposite directions is respectively equipped with the projection that is used to fix luminescence unit;
Pcb board one side surface in the described luminescence unit is provided with the contact of corresponding left and right sides electrode protrusion, and the opposite side surface is provided with LED lamp and resistance;
The middle part on described pcb board opposite side surface is provided with a resistance, and two ends respectively are provided with the LED lamp, and described LED lamp and resistance are SMD;
Two LED lamp reverse parallel connection settings each other in the described pcb board.
Than common automobile fuse, the beneficial effects of the utility model are also to be provided with luminescence unit at automobile fuse two electrode two ends, this luminescence unit is by pcb board and resistance is set in last series connection and the LED lamp constitutes, and the respective protrusions that luminescence unit is positioned at the housing bottom by two electrodes fixes and is electrically connected, thereby realized the connection of luminescence unit cleverly, effectively saved space shared in fuse; Used SMD resistance and LED lamp in pcb board in addition, the reverse parallel connection setting of two LED lamps has further guaranteed the insurance circuit polarity adaptive ability of entire product when fusing again, and visible entire product structure is small and exquisite reliable, is worthy to be popularized very much.
[description of drawings]
Below in conjunction with accompanying drawing in detail concrete structure of the present utility model is described in detail
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a luminescence unit structural representation of the present utility model.
[embodiment]
As shown in Figure 1; the utility model relates to a kind of automobile fuse with the fusing indication; it includes housing 1; be plugged with left and right sides electrode 2,3 in the housing 1; 2,3 at left and right sides electrode is electrically connected by fusible fusing conductor 4; and in order to guarantee enough bearing capacitys, the conductor of quick fuse protection when this fusing conductor 4 can be arranged to as the U-shaped of figure or S shape etc. that solid shape does not break down as the automobile protective circuit.Be respectively equipped with projection 201,301 in the side in opposite directions of left and right sides electrode 2,3, constitute a cavity that can be used for placing and fixing luminescence unit 5 between the bottom of this two projection 201,301 and housing 1 in housing 1 bottom.
Referring to Fig. 2 is the structural representation of luminescence unit 5; this luminescence unit 5 comprises the pcb board 501 of bottom; the upper surface middle part of pcb board 501 is provided with a Chip-R 503 that is used for current limliting is set; two ends respectively are provided with paster LED lamp 502; two LED lamps oppositely are provided with each other; and, guaranteed that all an indicator light all can provide bright lamp indication when fusing conductor 4 fuses thereby make product in use insert protective circuit forward or backwards via winding displacement one-tenth back connection in parallel current limliting Chip-R 503 in the pcb board.Corresponding, be provided with the electrode contacts 504 of corresponding left and right sides electrode 2,3 projectioies 201,301 in the lower surface of pcb board 501, this electrode contacts 504 slightly protrudes pcb board 501 surfaces, thereby guarantee the better realization fixing of cavity that whole luminescence unit 5 places left and right sides electrode 2,3 projectioies 201,301 and housing 1 bottom surface to constitute, reach and 2,3 good purposes that are electrically connected of maintenance of left and right sides electrode.
It is to be noted; of the present utility modelly be not limited to above-mentioned execution mode; any simple modification, equivalent variations and modification that any those skilled in the art do the foregoing description in based on technical solutions of the utility model all belong in the protection range of the present utility model.
