Description
Es ist bereits der Vorschlag gemacht worden, bei den in einem Gehäuse eingeschlossenen
elektrischen Schaltern den Anschlußraum im vorderen Teil des Gehäuses anzuordnen
und die Einführung der Schalterzuleitungen in das Gehäuse und ihren Anschluß an die
Schalterklemmen dadurch zu erleichtern, daß im unteren Teil des Gehäuses ein hinten
offener, von den Seiten und von unten zugänglicher Raum für die Einführung der
Schalterzuleitungen vorgesehen wird, von dem aus die Zuleitungen abgedichtet in den vorderen
Anschlußraum eingeführt werden. Erfindungsgemäß wird, für die Einführung der
Anschiußleitungen in den Anschlußraum eine besondere, am Schaltergehäuse lösbar befestigte,
mit Durchführungslöchem für die einzelnen Anschlußleitungen versehene Einführungsplatte
verwendet, gegen die die An-Schlußleitungen mit Hilfe einer Gummiplatte und einer an der Einführungsplatte angebrachten,
ebenfalls mit Durchführungsöffnungen versehenen Druckplatte einzeln abgedichtet sind. Die Einführungsplatte ist innerhalb
des Einführungsraumes von hinten gegen das Schaltergehäuse geschraubt, so daß der
Schalter ausgewechselt werden kann, ohne daß die Anschlußleitungen aus ihren Durchführungen
entfernt zu werden brauchen.
Bei dem in der Zeichnung dargestellten Ausführungsbeispiel der Erfindung ist α das
Schaltergehäuse, das im unteren Teil einen hinten offenen und von den Seiten und von
unten zugänglichen Raum b für die Einführung der Schalterzuleitungen c besitzt. Die
Leitungen c sind durch Durchführungslöcherd
einer Einführungsplatte e in den im Gehäuses vorn angebrachten Anschlußraum / eingeführt
und mit Hilfe der ebenfalls mit Durchführungslöchern versehenen Gummiplatte g The proposal has already been made to arrange the connection space in the electrical switches enclosed in a housing in the front part of the housing and to facilitate the introduction of the switch leads into the housing and their connection to the switch terminals by having a rear in the lower part of the housing open space, accessible from the sides and from below, is provided for the introduction of the switch leads, from which the leads are introduced into the front connection space in a sealed manner. According to the invention, for the introduction of the connection lines into the connection space, a special entry plate which is detachably attached to the switch housing and provided with feed-through holes for the individual connection lines is used, against which the connection lines are secured with the help of a rubber plate and a feed-through plate attached to the entry plate, also provided with feed-through openings Pressure plate are individually sealed. The lead-in plate is screwed inside the lead-in space from behind against the switch housing, so that the switch can be replaced without the connection lines having to be removed from their bushings.
In the embodiment of the invention shown in the drawing, α is the switch housing, which in the lower part has a space b , which is open at the rear and accessible from the sides and from below, for the introduction of the switch leads c . The lines c are inserted through feed-through holes d of an insertion plate e into the connection space / mounted in the front of the housing and with the aid of the rubber plate g, which is also provided with feed-through holes
und Druckplatte h gegen die Einführungsplatte e abgedichtet. Die Einführungsplatte e ist innerhalb des Einführungsraumes b von hinten gegen das Schaltergehäuse α geschraubt, so daß der Schalter ohne Entfer- 4S nung der Leitungen c aus den Durchfüh rungsplattene, g und h ausgewechselt werden kann.and pressure plate h sealed against the lead-in plate e. The introduction plate E is within the insertion space b from behind against the switch housing screwed α, so that the switch no distance-4 S c of the lines from the imple menting plates e, g and h may be substituted.
