Der Erfindung liegt die Aufgabe zugrunde, einen Sicherungseinsatz zu entwickeln, der eine deutliche Anzeige ohne abfallende Teile ermöglicht und bei dem der Körper durch die Anzeigevorrichtung nicht geschwächt ist. Die Lösung der geschilderten Aufgabe erfolgt nach der Erfindung durch einen Sicherungseinsatz nach Anspruch 1. Die Anzeigevorrichtung weist ein längs des Körpers des Sicherungseinsatzes verschieblich geführtes Signalelement auf, das in einem Sichtbereich beim Ansprechen desThe invention has for its object to develop a fuse link that allows a clear display without falling parts and in which the body is not weakened by the display device. According to the invention, the described object is achieved by a fuse link according to claim 1. The display device has a signal element which is displaceably guided along the body of the fuse link and which is in a visual range when the
Anzeigeschmelzleiters durch auffällige Ausführung den Ansprechzustand des Arbeitsschmelzleiters anzeigt. Das Signalelement kann aus elektrisch nichtleitendem Material gefertigt sein, so daß Berührungsschutz von Haus aus gegeben ist.Display fuse element shows the response status of the working fuse element due to its striking design. The signal element can be made of electrically non-conductive material, so that protection against accidental contact is inherent.
Der Sichtbereich kann auch eine Ausnehmung oder ein Sicht- fenεter in einer Abdeckung auf der Körperoberfläche sein. Dadurch wird die Anzeigevorrichtung mechanisch geschützt. Bei der Ausführung mit einem Sichtfenster oder mit einer fingersicheren Ausnehmung kann das Signalelement auch aus elektrisch leitendem Material bestehen. Unabhängig von der Materialwahl kann man durch einen Sichtbereich in einer Abdeckung besonders leicht die optische Auff lligkeit erhöhen.The viewing area can also be a recess or a viewing window in a cover on the body surface. This mechanically protects the display device. In the version with a viewing window or with a finger-safe recess, the signal element can also consist of electrically conductive material. Regardless of the choice of material, it is particularly easy to increase the visual conspicuity through a viewing area in a cover.
Der Sichtbereich läßt sich leicht am Körperrücken mittig ausführen, so daß die Funktion eines Mittenkennmelders erzielt wird, ohne die bei Mittenkennmeldern übliche Schwächung des Körpers.The field of vision can be easily carried out in the center of the back of the body, so that the function of a central indicator is achieved without the weakening of the body which is usual with central indicators.
Das Signalelement läßt sich vorteilhaft im Sichtbereich im verschobenen Zustand so ausführen, daß es sich von seiner im Sichtbereich im Ruhezustand gezeigten Farbe farblich unter- scheidet, wobei die unterscheidende Farbe sich auch von der Farbe der Abdeckung und bzw. oder der Farbe des Körpers des Schmelzeinsatzes deutlich abhebt. Die Erfindung soll nun anhand von in der Zeichnung grob schematisch wiedergegebenen Ausführungsbeispielen näher erläutert werden:The signal element can advantageously be implemented in the viewing area in the shifted state in such a way that it differs in color from its color shown in the viewing area in the idle state, the distinguishing color also differing from the color of the cover and / or the color of the body of the melting insert stands out clearly. The invention will now be explained in more detail with reference to exemplary embodiments shown roughly schematically in the drawing:
In FIG 1 ist ein Sicherungseinsatz im Längsschnitt wiedergegeben.In Figure 1, a fuse link is shown in longitudinal section.
In FIG 2 ist für das Ausführungsbeispiel nach FIG 1 die Ansicht auf den Rücken des Sicherungseinsatzes mit der Anzeigevorrichtung dargestellt.2 shows the view of the back of the fuse link with the display device for the exemplary embodiment according to FIG.
In FIG 3 ist der Sicherungseinsatz nach dem Ausführungsbeispiel gemäß FIG 1 in Ansicht von der Stirnseite veranschaulicht.3 shows the fuse link according to the embodiment of FIG 1 in a view from the front.
In FIG 4 ist die Anzeigevorrichtung nach FIG 1 herausgebrochen dargestellt und vergrößert wiedergegeben.In FIG. 4 the display device according to FIG. 1 is shown broken away and is shown enlarged.
Der Sicherungseinsatz nach FIG 1 ist als NH-Sicherung ausge- führt und im Längsschnitt dargestellt. Der Sicherungseinsatz weist einen Arbeitsschmelzleiter 1 und einen hierzu elektrisch parallel geschalteten Anzeigeschmelzleiter 2 auf. Eine Anzeigevorrichtung 3 enthält ein längs des Körpers 4 des Schmelzeinsatzes verschieblich geführtes Signalelement 5, das in einem Sichtbereich 6, man vergleiche FIG 4, beimThe fuse link according to FIG. 1 is designed as an NH fuse and is shown in longitudinal section. The fuse link has a working fuse element 1 and a display fuse element 2 which is electrically connected in parallel with this. A display device 3 contains a signal element 5 which is displaceably guided along the body 4 of the melting insert and which in a viewing area 6, compare FIG
.Ansprechen des Anzeigeschmelzleiters verschoben wird und durch auffällige Ausführung den Ansprechzustand des Arbeitsschmelzleiters 1 anzeigt. Das Signalelement 5 der Anzeigevorrichtung 3 ist gegen den Zug durch den Anzeigeschmelzleiter 2 mittels eines Federelementes 7 gespannt. Das Federelement 7 liegt im Ruhezustand unter Zug durch den Anzeigeschmelzleiter 2 an der Abschlußplatine 8 an. Wenn der Anzeigeschmelzleiter 2 infolge des Durchschmelzens des Arbeitsschmelzleiters 1 bei üblicher entsprechender Abstimmung durchschmilzt, wird das Federelement 7 freigegeben, so daß das daran befestigte Signalelement 5 unter einer Abdeckung 9 verschoben wird. In einem Sichtbereich 6 erscheint dann beim Ansprechen des Anzeigeschmelzleiters 2 das Signalelement 5 in einer auffälligen Ausfüh- rung . Die elektrische Verbindung in Parallelschaltung des Anzeigeschmelzleiters 2 zum Arbeitsschmelzleiter 1 erfolgt über die Messerkontakte 10 durch Aufreiten des Federelementes 7 auf den Messerkontakten. Wenn das Federelement 7 aus einem nicht ausreichend elektrisch leitenden Material besteht, kann auch eine elektrisch leitende Schicht im Bereich zwischen der Anbringung des Anzeigeschmelzleiters 2 und dem Messerkontakt 10 vorgesehen werden. Die Anschlußplatinen 8 können aus Isoliermaterial gefertigt sein. Bei einer derartigen Ausführung ist es aus Gründen des BerührungsSchutzes vorteilhaft, das Federelement 7 elektrisch isolierend zu beschichten..Response of the display fuse element is shifted and indicates the response state of the working fuse element 1 by conspicuous execution. The signal element 5 of the display device 3 is tensioned against the train through the display fuse element 2 by means of a spring element 7. The spring element 7 is in the idle state under tension by the display fuse element 2 on the end plate 8. If the display fuse element 2 melts as a result of the melting of the working fuse element 1 with customary corresponding coordination, the spring element 7 released so that the attached signal element 5 is moved under a cover 9. In a visible area 6, the signal element 5 then appears in a conspicuous version when the fuse element 2 responds. The electrical connection in parallel connection of the display fuse element 2 to the working fuse element 1 takes place via the knife contacts 10 by spreading the spring element 7 on the knife contacts. If the spring element 7 consists of an insufficiently electrically conductive material, an electrically conductive layer can also be provided in the area between the attachment of the display fuse element 2 and the knife contact 10. The connection boards 8 can be made of insulating material. In such an embodiment, for reasons of protection against contact, it is advantageous to coat the spring element 7 in an electrically insulating manner.
Im Ausführungsbeispiel nach FIG 2 ist das Signalelement im Sichtbereich 6 bandförmig ausgeführt, wobei der Sichtbereich durch eine Ausnehmung in der Abdeckung 9 auf der Körperoberfläche gebildet ist. Das Signalelement weist im Sichtbereich 6 im verschobenen Zustand eine Signalwirkung dadurch auf, daß es sich von seiner im Sichtbereich im Ruhezustand gezeigten Farbe unterscheidet, wobei sich die unterscheidende Farbe auch von der Farbe der Abdeckung 9 und der Farbe des Körpers 4 des Schmelzeinsatzes abhebt. Im Ausführungsbeispiel wird beim Abheben der Feder 7 der auffällige Bereich 11 in den Sichtbereich 6 hineingezogen. Beim Verschieben des Signal- ele entes 5 unter der Abdeckung 9 kann also eine farbige Markierung im Sichtbereich 6 sichtbar werden, so daß optisch eine Art Farbumschlag auf sichere und wirtschaftliche Weise erzielt wird.In the exemplary embodiment according to FIG. 2, the signal element is designed in the form of a band in the viewing area 6, the viewing area being formed by a recess in the cover 9 on the body surface. The signal element has a signal effect in the viewing area 6 in the shifted state in that it differs from its color shown in the viewing area in the idle state, the distinguishing color also being different from the color of the cover 9 and the color of the body 4 of the melting insert. In the exemplary embodiment, when the spring 7 is lifted off, the conspicuous region 11 is drawn into the visible region 6. When the signal element 5 is moved under the cover 9, a colored marking can thus become visible in the viewing area 6, so that a kind of color change is achieved optically in a safe and economical manner.
Wenn das an der Stirnseite des Sicherungseinsatzes angebrach- te Federelement 7 durch eine entsprechende Form- und bzw. oder Farbgebung als Stirnanzeiger ausgeführt ist, läßt sich überraschenderweise bei Sicherungseinsätzen dieser Art eineIf the spring element 7 attached to the end face of the fuse link has a corresponding shape and / or or coloring is designed as a front indicator, can surprisingly be used in fuse links of this type
Kombination von Mitten- und Stirnanzeige ermöglichen. Allow combination of center and front display.
