Abstract
The utility model relates to a fuse wire, in particular to the fuse wire used in low-voltage and large capacity fuse whose working fuse wire(1) is monitored by a display fuse which is electrically connected in series with the working fuse wire. The display fuse wire allows a spring element(4) in front of a slab(5) to be tightened. The spring element(4) is connected to the signal component(7) which can be vertically moved and inducted along the fuse shell(6). The signal component shows the working fuse state in a visual area(8) through an obvious structure. According to the utility model, the signal component(7) is designed as a film and is designed much narrower at the transition area(11) than the visual area(12); while the signal component in the head region(13) is gradually thinned into a tip with the head region larger than the hole(14) in initial width.
Description
The utility model relates to a kind of fuse, and in particular for the fuse of the big capacity fuse of low pressure, its work fuse is subjected to a monitoring of the indication fuse of electricity parallel connection with it.Indication fuse makes the spring element tensioning before the slab.This spring element also is connected with a signal element that vertically can be moved guiding along the fuse housing, this signal element when indication fuse fuses in a visible range blown state by noticeable structure demonstration work fuse.A kind of like this fuse known (DE-U-29718230).
The fuse that has a display unit usually in the display unit zone its housing relatively weaker.Especially when carrying out the demonstration of so-called central authorities, housing is the quilt weaknessization in a key area.In above-mentioned fuse, can guide along the housing back of fuse as much as possible by making signal element, rather than in the tunnel type inner chamber of housing, guide, can avoid this structure reduction.Yet also can be, and steering signal element where necessary worthily with a cover plate guard signal element.
Be connected in fact more complicated between the portable signal element that an available film is made and the spring element that can be used as so-called end feature alarm (Stirnkennmelder) simultaneously.Bonding, hot pressing, contraction connect, have all proved very trouble in practice with the shrinkable film binding.
The purpose of this utility model is further to develop the fuse of the above-mentioned type, improves wherein being connected of signal element and spring element.
The purpose of this utility model realizes by the described fuse of claim 1.Signal element is designed to film at this, and it is designing than narrower in visible range in a transition region of spring element; And in a head zone that is used for fixing on spring element, being tapered into a tip, the original width of this head zone is bigger than the through hole width on the slab.Signal element utilizes this tip can insert in the through hole of slab, wherein, when carrying out the transition to the head zone of broad, form hypotenuse (Anlaufschraegen), this feasible signal element made from thin-film material is rolled, thereby make it to reach an installation site the most at the beginning, signal element can be pulled out slab after a while.Narrow transition region between visible range and head zone can be passed the through hole on the slab, and visible range then can be blocked by slab or insulation/sealant.Wide head zone allows signal element to couple together with conventional art described above and spring element.
In a favourable design, signal element has the oblique chamfering that at least one attenuates strongly when attenuating the zone carrying out the transition to from its head zone.Utilize this project organization, signal element is easy especially when passing slab.
In further designing, spring element has top that a stamping-out goes out, and it has a reversing with respect to the draw direction of signal element.This top can the signal element of film like can being pressed on the spring element thus perpendicular to spring element makes the top thorn number of leaking information element.But the barb fixed signal element on top, and need not to take other fixation.For the purpose of further insuring, the draw direction of top inverse signal element bend in the flat sections of spring element.Signal element especially can cut from tape loop by die-cut.
By the accompanying drawing illustrated embodiment the utility model is described in detail below, in the accompanying drawing:
Fig. 1 illustrates a signal element, and its middle part is disconnected;
Fig. 2 is the partial sectional view of the important area of a fuse;
Fig. 3 illustrates an embodiment of spring element.
Fuse shown in Figure 2 has a work fuse 1, and a knife contacts 2 is arranged respectively at its two.One indication fuse 3 is in parallel with this work fuse electricity, and with a spring element tensioning be fixed in the two boards base 5 wherein on one.The top of this two boards base is common clamping plate form.In Fig. 2, except the resting position (state) that spring element is shown, it also is shown flicks state.One signal element 7 can move guiding along the housing 6 of fuse.In a visible range 8, when indication fuse 3 fusing, when spring element 4 flicks, in the viewing area 9 of fuse compelling structure can appear, and this shows that fuse fuses.Because indication fuse and work fuse mutual response, the work fuse also can fuse, thereby causes fuse to open circuit.
In the embodiment shown in Figure 2, signal element 7 is blocked by a cover plate 10.Signal element 7 can be guided at housing 6 backs of fuse by this cover plate 10.In addition, in the housing 6 of fuse, also have a flat guide groove that is used for display element, cover plate will only cover signal element from the outside like this.
Signal element 7 is designed to film according to Fig. 1, and it is designing than narrower in visible range 12 in a transition region 11 of spring element.In a head zone 13 that is used for fixing on spring element 4, signal element 7 is tapered into a tip.The original width of this head zone 13 is bigger than 14 width of the through hole on the slab 5.Spring element 4 can straddle on knife contacts 2 by known mode.
Signal element 7 shown in Figure 1 has two oblique chamferings 15 carrying out the transition to from its head zone when it attenuates the zone.The degree that head zone attenuates rapidly herein is bigger than the degree that attenuates that signal element 7 thins down to the most advanced and sophisticated zone that attenuates.Two oblique chamferings like this help signal element 7 to crispatura to insert in the through hole 14.
Signal element 7 can cut from tape loop by die-cut.
If top 16 have a barb as shown in Figure 3, the signal element of being pressed just is hooked on before top upset on top 16.In the wide head zone 13 of signal element 7, can adopt traditional technique for fixing that signal element and flexible member 4 are linked together.One top 16 the time when being shaped on spring element 4, described head zone also can design narrowlyer generally.In any case, signal element 7 all can be set up a kind of gapless connection with spring element 4.Signal element can be made by the tear-resistant polyethylene film of elasticity.
