Abstract
The utility model relates to a fuse with displaying means for automobiles, which comprises an outer shell 1, a fuse wire 2 and a plug pin 3. The utility model is characterized in that the utility model also comprises an LED 4 and a current-limiting resistor R, wherein, the LED 4 is connected in series with the current-limiting resistor R, and is connected in parallel with the fuse wire 2. The utility model has the advantages of simple structure, visual display, and convenient replacement. The on-off state of the fuse is convenient to be observed.
Description
The utility model relates to a kind of fuse protecting device, specifically is meant the fuse that automobile shows with band.
The automobile fuse of conventional usefulness does not have the display part, when automobile is in operation, in case that insures or has some insurances to be burnt out simultaneously, at this moment, needs your inspection one by one, and is so too time-consuming.(notification number: 214-5440), it is by fuse-link, and pin and plastic casing constitute for Chinese patent literature disclosed a kind of " automobile chip fuse ".Fuse-link is positioned on two pins, and mid portion is the necking down structure, and 90 ° of the horizontal bendings in top constitute the convex shape structure with two pins; Plastic casing includes transparent windows, the purpose of said structure is to make fuse to have best ampere-second characteristic, be convenient to observe the fuse-link on off operating mode, adopt the fuse of this structure, the on off operating mode that does not obviously fundamentally solve fuse-link is difficult for the shortcoming of observation.
The purpose of this utility model is to propose the fuse that a kind of automobile shows with band, and it can make the observation to the fuse-link on off operating mode come into plain view, to be convenient for changing the fuse that burns out.
The purpose of this utility model is to realize like this, it comprises shell 1, fusible link 2 and inserted sheet 3, and its primary structure is that it comprises that also light-emitting diode 4 (LED) and current-limiting resistance R form, described light-emitting diode 4 is with after current-limiting resistance R connects, and is in parallel with fusible link 2.
Good effect of the present utility model is
1) fuse that adopts the automobile of this structure to show with band, when automobile in enforcement, if that road fusible link burns out, the luminous immediately demonstration of light-emitting diode shows that promptly there is fault on this road.
2) the utility model is simple in structure, and intuitive display is convenient to observe the fuse-link on off operating mode, and it is convenient that it is changed, and is convenient to maintenance, is highly suitable for using in the more automobile circuit of fuse.
The utility model is described in further detail below in conjunction with accompanying drawing,
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the electrical connection graph of fusible link and light-emitting diode and current-limiting resistance in the utility model,
Fig. 3 is connect a electrical connection graph behind the pressure limiting diode of light-emitting diode among Fig. 2.
As shown in Figure 1 and Figure 2, the utility model comprises shell 1, fusible link 2 and inserted sheet 3, its primary structure is, it comprises that also a light-emitting diode 4 (LED) and current-limiting resistance R form, the base of described light-emitting diode 4 is fixed on the inner chamber of shell 1, with after current-limiting resistance R connects, be connected in parallel on the two ends of fusible link 2.
For light-emitting diode and current-limiting resistance are contacted with fusible link reliably, ply-yarn drill 5 and ply-yarn drill 6 also are housed on inserted sheet 3, after above-mentioned light-emitting diode and the current-limiting resistance R series connection, their another connector lug is electrically connected with inserted sheet 3 by lead respectively, and by ply-yarn drill 5 and ply-yarn drill 6 junction of above-mentioned lead and inserted sheet is fixed.
For making the utility model be adapted to different automobile electronic circuit structures, the value of above-mentioned current-limiting resistance R should be different, can be divided into I type and II type, and wherein the R in the I type is 2-2.5K Ω, and the R value in the II type is about 4K Ω.
Because the withstand voltage of light-emitting diode is generally lower, connects (as shown in Figure 3) with above-mentioned light-emitting diode 4 and current-limiting resistance R so also need be provided with a pressure limiting diode D in side circuit.
Claims (3)
1, a kind of automobile is with being with the fuse that shows, it comprises shell (1), fusible link (2) and inserted sheet (3), it is characterized in that, it comprises that also light-emitting diode (4) and current-limiting resistance R form, described light-emitting diode (4) is with after current-limiting resistance R connects, and is in parallel with fusible link (2).
2, the fuse that shows with band according to the automobile in the claim 1, it is characterized in that, ply-yarn drill (5) and ply-yarn drill (6) also are housed on inserted sheet (3), the wherein connector lug of described light-emitting diode and current-limiting resistance R is to be electrically connected with lead, the other end of this lead is electrically connected with inserted sheet (3), and by ply-yarn drill (5) and ply-yarn drill (6) junction of lead and inserted sheet is fixed.
3, according to the fuse of the automobile in the claim 1 with the band demonstration, it is characterized in that it also comprises a pressure limiting diode D, this pressure limiting diode D connects with above-mentioned light-emitting diode 4 and current-limiting resistance R.
