Abstract

Bei einem elektrischen Steckerstift ist durch eine gegen Federkraft verschiebbare Isolierhülse (12) Berührungsschutz erreicht. An electrical connector pin is replaced by a Spring-loaded insulating sleeve (12) protection against accidental contact reached.

Zur Sicherstellung der zuverlässigen Funktion dieses Berührungsschutzes, auch nach häufigem Gebrauch des Steckerstiftes, ist die verschiebbare Isolierhülse (12) durch eine selbsttätig eingreifende Sperre (14, 15, 16) gegen unbeabsichtigtes Zurückschieben gesichert. To ensure the reliable functioning of this Protection against contact, even after frequent use of the Plug pin, the sliding insulating sleeve (12) through an automatically engaging lock (14, 15, 16) against secured against unintentional pushing back.

Bei einer besonders zweckmässigen, von Hand lösbaren Sperre (14, 15, 16) stösst ein in einer Längsnut (21) des Isoliergriffs (8) geführter Vorsprung (14) der verschiebbaren Isolierhülse (12) an einer in die Längsnut (21) eingreifenden Sperrzunge (15) an, die durch Fingerdruck auf eine als Kniehebel wirkende gewölbte Blattfeder (17) aus der Längs­ nut (21) heraushebbar ist; der Vorsprung (14) weist dabei eine zur anstossenden Fläche der Sperrzunge (15) etwa parallele Fläche und auf der entgegengesetzten Vorderseite eine schräge Gleitfläche auf, die im spitzen Winkel zur Steckerachse verläuft. With a particularly useful, hand-detachable Lock (14, 15, 16) pushes into a longitudinal groove (21) of the Insulating handle (8) guided projection (14) of the displaceable Insulating sleeve (12) on an engaging in the longitudinal groove (21) Locking tongue (15) on the finger pressure on an as Curved leaf spring (17) acting from the longitudinal groove (21) can be lifted out; the projection (14) has one to the abutting surface of the locking tongue (15) approximately parallel surface and on the opposite front an inclined sliding surface that is at an acute angle to the Connector axis runs.
