Definitions
- the invention relates to a fuse link, in particular for low-voltage high-performance fuses, NH fuses, the working fuse by an electrical display fuse element arranged in parallel is monitored by a signal element in a display device against the train through the display fuse element by means of a spring element is tensioned.
- display devices are known in various designs. See e.g. DE-A-3 203 211.
- Display devices are usually on the front sides arranged the body of the fuse link. They are too Center indicator on the center of the fuse link known in different versions. With all display devices there is often a risk that the signal element is thrown out when the fuse element melts and indicates the response of the working fuse.
- the display pearl is through the display fuse element fixed in a recess in the body of the fuse link, the display fuse element being threaded through holes and on the end plates or on the contact blades is connected in a contacting manner. If the display fuse element melts through, the display bead comes out of the recess the fuse body flung out.
- the falling out Display pearl and possibly additional spring elements to Ensuring the display function can fall into plants and cause malfunctions or contamination.
- the invention has for its object a fuse link to develop the with a clear display without falling Parts works.
- Such a display device loses in response no parts and it can be designed so flat that the Body of the fuse link designed as a center indicator not weakened in the critical area becomes.
- the signal element can be in the bow-shaped spring element be locked in a locking opening, which is a highly mechanized manufacturing enables.
- the locking opening is perpendicular to the pivot axis is designed so far in the manner of an elongated hole that the signal element when the spring element is opened as a result Melting of the display fuse element in the display device can repel and emigrate. This will make it Unfolding is not hindered in confined spaces.
- the receptacle for the fuse element in the bow-shaped Spring element can advantageously be designed as a bushing through which the display fuse element is inserted before the signal element is put on.
- the imaginary pivot axis of the spring element with the Signal element can be perpendicular to the longitudinal axis of the body of the Fuse insert can be arranged. It is also an arrangement possible in the direction of the longitudinal axis.
- the display device can be centered on the body of the fuse link Center indicator can be arranged.
- the bow-shaped spring element in the display device to engage. If the bow-shaped spring element Forms support legs, it can firmly snap into place promote the signal element under pressure. For this, the Support legs from the bushing of the spring element and at least one suitably bent tab of the spring element be educated.
- FIG. 1 shows a fuse link with a center indicator reproduced in longitudinal section.
- Figure 2 is a display device with a broken view Enlarged on the basis of a type of representation according to FIG. 1 illustrated. The one opened with the signal element The spring element is shown in dashed lines.
- FIG. 3 shows for the in the display device according to FIG or 2 performed display fuse element an embodiment for a contact spring for making contact on the end plate for a conductive connection to the working fuse shown.
- the fuse link according to FIG 1 in the design as an NH fuse has a working fuse 1 and one for this display fuse element 2 arranged in parallel.
- a signal element 3 is on in a display device 4 a bow-shaped spring element 5 held.
- the spring element 5 is in turn pivotable in the display device 4 held.
- One is spaced from the imaginary swivel axis Recording 6 designed for the display fuse element 2.
- the signal element 3 is in the bow-shaped spring element 5 by means of a knob 8 in one Locking opening 7 engaged.
- a slot-like Execution of the locking opening 7 cut out Rag 9, which is behind a roof-shaped formation of the knob 8 intervene that the signal element 3 from the spring element 5th could fall out.
- the receptacle 6 for the Display fuse element 2 in the bow-shaped spring element 5 as Bushing formed through which the display fuse element 2 can be inserted before moving the signal element 3 applies.
- the display device 4 according to FIG. 2 is on the body 10 of the fuse link in the middle as a center indicator arranged. Such a display device can run flat so that the body is only slightly weakened is. Such a display device can be manufacture highly mechanized.
- a highly mechanized production is promoted if that bow-shaped spring element 5 snapped into the display device 4 is, as in FIG 2 for an embodiment is illustrated.
- the bow-shaped spring element 5 forms support legs, so that when the signal element 3 engages under pressure, the spring element is stable.
- the support legs of the receptacle 6 of the spring element and at least one bent standing rag 11 are formed.
- the standing rag 11 is based, for example, behind the drawing plane a surface from which a blind hole-like opening for snapping the spring element 5 goes out in depth.
- a highly mechanized production of the fuse link with the display device is further extended by contact springs 12 promoted according to FIG 3.
- the display fuse element 2 is here at least at one of its two ends for electrical connection jammed with the working melt current conductor 1 by he against an abutment 13 by a leg of the contact spring 12 is jammed.
- the contact spring 12 forms on the other hand a compression spring 14, which due to its dimensioning and or spring arrangement against an end plate 15.
- the end plate 15 by a Sealing body 16 against the body 10 of the fuse link sealed.
