Abstract
The invention relates to a fuse link, especially for low-voltage high-performance fuses, whose working fuse element (1) is controlled by an electronically placed parallel indicator fuse (2) and in which a signal element (5) located in an indicator device (3) is biased against the tension of the indicator fuse (2) by means of a spring unit (7). The said indicator device (3) comprises slides along the body (4) of the fuse link (5) clearly indicating in a visual area (6) the state of response of the fuse link (1) upon response of the indicator fuse (2).
Description
The present invention relates to a kind of fuse link that especially can be used for the low-pressure high-power safeties, its work insurance silk by one with it the demonstration fuse of electric power parallel connection monitored, wherein signal element is shown the pulling force tensioning of fuse by spring element in display unit.
The fuse link that has display unit weakens the fuse link housing in the display unit scope usually to some extent.Particularly on so-called center display, the housing of fuse is weakened in the viewing area scope.The display unit that is designed to center display on market shows pearl work with glass or plastics.Show that pearl passes the demonstration fuse and is positioned in the groove of fuse link housing, show that wherein fuse passes and is connected on shut or the contactor blade by the hole.When showing blown fuse, show in the groove of pearl by the fuse link housing and eject, demonstrate the action of fuse link thus.The demonstration pearl that falls down also is included as sometimes and guarantees the necessary spring element of Presentation Function, may drop in the device and has influence on function or form impurity.
The objective of the invention is to, develop a kind of fuse link, it can realize clear the demonstration and the parts that do not drop, and such demonstration can not make housing weakened.
The objective of the invention is to realize by the described fuse link of claim 1.This display unit has a vertically signal element movably along the fuse link housing, and when showing the fuse action, signal element demonstrates the operate condition of work insurance silk by attractive structure in the viewing area.Signal element can be made by electrically non-conductive material, and itself just forms electrical shock protection.
The viewing area can be a groove or the form on the surface of shell cover plate.Make display unit obtain mechanical protection thus.Signal element also can be made by electric conducting material in the structure that has form or finger protection groove.People can especially easily improve visual with the form that material is selected irrespectively to pass through on the cover board.
The viewing area can form in the middle of back side of shell easily, with the function of display alarm in the middle of realizing, and can not cause the common weakening to housing in middle display alarm.
Be in the signal element that moves in the state of back and show the color in viewing area when being different from it remains static in the viewing area, wherein said two kinds of different colors should be set off out by the color of the color of cover plate and/or fuse housing.
The present invention is described in further detail below by embodiment that accompanying drawing illustrates roughly:
Fig. 1 is the longitdinal cross-section diagram of fuse link.
Fig. 2 is in the embodiment shown in fig. 1 to the view at the back side of the fuse link that has display unit.
Fig. 3 is the front view of the fuse link in embodiment illustrated in fig. 1.
Fig. 4 is that diagrammatic sketch is amplified in the part of display unit shown in Figure 1.
Fuse link shown in Figure 1 is designed to low-pressure high-power safeties (NH-Sicherung), its longitdinal cross-section diagram shown in Figure 1.This fuse link has a work insurance the silk 1 and demonstration fuse 2 of electric power parallel connection with it.One display unit 3 comprises one along the vertical signal element 5 movably of fuse link housing 4, and this signal element 5 in viewing area 6 (with reference to Fig. 4) produces the operate condition that moves and indicate work insurance silk 1 by attractive structure when showing the fuse action.The signal element 5 of display unit 3 is shown the pulling force tensioning of fuse 2 by a spring element 7.Spring element 7 is shown that under static state the tension of fuse 2 abuts on the terminal block 8.When also fusing under showing the situation that fuse 2 fuses in common corresponding coupling owing to work insurance silk 1, spring element 7 is released, and the feasible signal element of fixing on it 5 also produces below cover plate 9 and moves.Therefore signal element 5 appears at viewing area 6 with attractive structure when showing fuse 2 actions.Demonstration fuse 2 is realized by the spring element 7 that straddles on the knife contacts at the process knife contacts 10 in parallel on the circuit with work insurance silk 1.When spring element 7 is made by bad electric conducting material, also can in the position that shows between fuse 2 devices and the knife contacts 10, mix conductive layer.Terminal block 8 can be processed into by insulating material.The spring element 7 that is insulated coating in the structure of this form is owing to its protection against electric shock has advantage.
Signal element is band shape and appears in the viewing area in embodiment illustrated in fig. 2, and at this, the viewing area is made of the groove in the cover plate on surface of shell 9.Color when signal element is different from it and remains static by demonstration in viewing area 6 through moving the back in the viewing area is brought into play the signal effect, should clearly set off out from the color of the color of cover plate 9 or fuse housing 4 in this different color.When spring 7 was upspring, attractive position 11 was drawn in the viewing area 6 in the present embodiment.When signal element 5 just can be seen the mark of a colour in viewing area 6 when cover plate 9 times is mobile, thereby reach the purpose of optic metachromatic with reliable and economic method.
When the positive spring element of settling 7 of fuse link is designed as the front indicating device by corresponding shape or color, the combination that shows with the front in the middle of on this class fuse link, can realizing astoundingly.
Claims (5)
