Abstract
The invention concerns a fuse-link, in particular for low-voltage high-breaking-capacity (l.v.h.b.c.) fuses, whose working fuse element (1) is monitored by an indicator fuse element (2) which is disposed electrically parallel thereto, a spring element holding a signalling element (3) in an indicator device (4) against the traction exerted by the indicator fuse element (2). According to the invention, the signalling element (3) is held in the indicator device (4) on a stirrup-shaped spring element (5) which is in turn held pivotably in the indicator device (4) and, at a spacing from the imaginary pivot axis, forms a mounting (6) for the indicator fuse element (2).
Description
The present invention relates to a kind of fuse link that especially can be used on the low-pressure high-power safeties, its work insurance silk by one on circuit demonstration fuse in parallel with it monitored, wherein a signal element is shown the pulling force tensioning of fuse by spring element in a display unit.This class display unit is known different types of structure.
Display unit generally is installed in the end of fuse link housing.Known center display is arranged on the housing middle part of the fuse link of different types of structure.Often occur danger in all display unit, promptly when showing blown fuse, when the work insurance silk sent action, signal element was launched out.
Display unit as center display on market shows pearl work with glass or plastics.Showing that pearl passes shows that fuse is fixed in the groove in the fuse link housing, this show fuse pass through hole and be connected to shut or contactor blade on.When showing blown fuse, show in the groove of pearl by the fuse link housing and eject.The demonstration pearl that falls down also is included as sometimes and makes the reliable and spring element set up of Presentation Function, may drop in the device and has influence on function or become impurity.
The objective of the invention is to develop a kind of fuse link, it can be worked under the situation that the parts that do not drop just can clearly show.
The objective of the invention is to realize by the described fuse link of claim 1.Signal element is fixed in display unit on the semielliptic spring element, but this semielliptic spring element itself is fixed on the display unit to deflection again.On the semielliptic spring element, be provided with a fixed cover that is used to show fuse apart with imaginary rotating shaft.
This class display unit the time does not have the parts that can drop in action, and can design more flatly, and the fuse link housing with structure as center display is without prejudice in key area.This signal element is sticked in the bayonet socket in the semielliptic spring element, and this is possible in highly-mechanized production.
More advantageously, bayonet socket is made into the slotted hole shape perpendicular to yawing axis, makes described signal element can be hit and deviate from by quilt in display unit when showing that the blown fuse spring element opens.This opens in small space and is not hindered thus.
Show that fuse fixing on the semielliptic spring element can be advantageously realize in the mode of fixed sleeving, showed that before signal element is installed fuse is threaded in the fixed cover.
The imaginary yawing axis that has the spring element of signal element can be perpendicular to the longitudinal axis setting of fuse link housing.Certainly be arranged on the y direction and also be fine.Display unit can be used as center display and is installed in the middle of the fuse link housing.
More advantageously the semielliptic spring element is sticked in the display unit.When the semielliptic spring element constitutes supporting leg, can make signal element kayser stably by pressure.At least one suitable curved tabs (Lappens) constitutes supporting leg on this can be by fixed cover on the spring element and spring element.
The embodiment that simply illustrates by accompanying drawing is described in further detail the present invention below, in the accompanying drawing:
Fig. 1 is the longitdinal cross-section diagram that has the fuse link of a center display;
Fig. 2 is the partial enlarged view of the display unit of version shown in Figure 1;
Fig. 3 is the demonstration fuse in Fig. 1 or the display unit shown in Figure 2 connects work insurance silk end plate by the contact spring of the closing of contact embodiment.
Has work insurance silk 1 as the fuse link of low-pressure high-power safeties and demonstration fuse 2 in parallel on circuit according to Fig. 1.Signal element 3 is clamped on the semielliptic spring element 5 in the display unit 4.But be fixed in the display unit 4 to these semielliptic spring 5 deflections own.The fixed cover 6 that shows fuse 2 keeps certain distance ground to constitute with imaginary rotating shaft.Referring to Fig. 2.
In embodiment illustrated in fig. 2, the signal element 3 on semielliptic spring element 5 passes through a lateral pin 8 kaysers in breach 7 the insides.In this slotted hole structure at breach 7, the flange 9 of the lid-like back that is stuck in lateral pin 8 that freely cuts out has stoped signal element 3 to fall from spring element 5.When spring element 5 owing to showing that blown fuse is opened, the signal element 3 in the display unit is hit and is deviate from, even if make open in the space of flat narrow not interrupted yet.
In embodiment illustrated in fig. 2, the fixed cover 6 of the demonstration fuse 2 on the semielliptic spring element 5 constitutes with the form that wears pipe, before signal element 3 is installed, shows that fuse 2 can be pierced in this fixed cover.In embodiment illustrated in figures 1 and 2, the imaginary yawing axis of spring element 5 is perpendicular to the longitudinal axis setting of fuse link housing 10.It is middle as center display that display unit 4 shown in Figure 2 is installed in fuse link housing 10.The display unit of this form can be made flat, makes housing that very little weakening structurally only be arranged.This class display unit can be produced on high mechanization ground.
When semielliptic spring housing 5 is snapped in the display unit 4 (just as the embodiment among Fig. 2 is represented time), just promoted high mechanization production.More advantageously constitute supporting leg by semielliptic spring element 5, when signal element 3 during by kayser, the spring element effect of being stressed can keep stable like this.Wherein can constitute supporting leg by the fixed cover on the spring element 6 and at least one crooked stator 11.This stator 11 for example is supported on the plane of diagram back, plane, and the plane down constitutes a blind-hole type opening that is used for spring clip element 5 thus.
The high mechanization production that has the fuse link of display unit is further promoted by contact spring 2 shown in Figure 3.Show that wherein the end that fuse 2 at least should be in its two ends be that electrical connection and work insurance silk 1 clamp, this is that a leg by contact spring 12 is clamped in it on bearing 13.The other end of contact spring 12 constitutes a stage clip 14, and this stage clip is installed on the end plate 15 by size design and/or layout.This end plate 15 is sealed on the fuse link housing 10 by a seal 16 in the present embodiment.
