Abstract

In an electrical connector pin, electric shock protection is achieved by means of an insulating sleeve (12) which can be moved against the force of a spring. To ensure the reliable operation of this electric shock protection, even after frequent use of the connector pin, the movable insulating sleeve (12) is protected by an automatically engaging block (14, 15, 16) against being pushed back unintentionally. In a particularly practical block (14, 15 16), which can be released manually, a projection (14) of the movable insulating sleeve (12), guided in a longitudinal slot (21) of the insulating grip (8), abuts on a locking tab (15), engaging in the longitudinal slot (21), which can be lifted out of the longitudinal slot (21) by finger pressure on an arched leaf spring (17), acting as a bellcrank; in this arrangement, the projection (14) has a surface which is approximately parallel to the abutting surface of the locking tab (15) and an oblique sliding surface on the opposite front side, which runs at an acute angle to the connector axis. <IMAGE>

Description

Die Erfindung betrifft einen elektrischen Steckerstift mit Berührungsschutz durch eine gegen eine Federkraft verschiebbare Isolierhülse.The invention relates to an electrical connector pin with touch protection by means of an insulating sleeve which can be displaced against a spring force.

Bei einem einpoligen Laboratorienstecker, der z.B. in der Firmenzeitschrift der Anmelderin "Die Brücke zum Kunden" Nr. 81 auf Seite 6 abgebildet und beschrieben ist, ist über den elektrischen Steckerstift eine Isolierhülse geschoben, die beim Einführen des Stiftes in eine Steckbuchse gegen eine Schraubendruckfeder zurückgeschoben wird. Die Spitze des Stiftes, die aus der vorgeschobenen Isolierhülse noch etwas herausragt, besteht ebenfalls aus Isoliermaterial. Dadurch ist verhindert, daß unter Spannung stehende Metallteile des Steckerstiftes berührt werden können, wenn die Isolierhülse nicht zurückgeschoben wird. Dies ist aber nicht mit Sicherheit gewährleistet, weil versehentliches Zurückschieben der Isolierhülse bei unvorsichtigem Umgehen mit dem Laboratoriumsstecker nicht ausgeschlossen ist. Dieser Nachteil ist durch die Maßnahme nach dem kennzeichnenden Teil des Anspruches 1 beseitigt.With a single-pole laboratory connector, e.g. In the company magazine of the applicant "The Bridge to the Customer" No. 81 on page 6 is depicted and described, an insulating sleeve is pushed over the electrical plug pin, which is pushed back against a helical compression spring when the pin is inserted into a socket. The tip of the pin, which still protrudes a little from the inserted insulating sleeve, is also made of insulating material. This prevents live metal parts of the connector pin from being touched if the insulating sleeve is not pushed back. However, this is not guaranteed with certainty because accidental pushing back of the insulating sleeve cannot be ruled out if the laboratory plug is handled carelessly. This disadvantage is eliminated by the measure according to the characterizing part of claim 1.

Für die praktische Brauchbarkeit eines Laboratoriumssteckers mit dem erfindungsgemäßen Steckerstift ist es entscheidend, daß die Sicherung gegen unbeabsichtigtes Zurückschieben der Isolierhülse auch nach häufigem Gebrauch des Steckers noch zuverlässig ge - währleistet ist.For the practical usability of a laboratory plug with the plug pin according to the invention, it is crucial that the protection against unintentional pushing back of the insulating sleeve is still reliably guaranteed even after the plug has been used frequently.

Wenn die Sperre gemäß Anspruch 2 von Hand lösbar ist, muB dazu eine verhältnismäßig groBe Kraft erforderlich sein, die nicht versehentlich zustande kommen kann. Diese Voraussetzung ist bei der Ausführungsform des erfindungsgemäßen Steckerstiftes nach Anspruch 3 in einfacher Weise zu erfüllen. Wenn die Federkraft der Blattfeder entsprechend bemessen ist, ist ein kräftiger Fingerdruck auf deren Mittelteil erforderlich, um das Vorderteil nach außen auszulenken und dadurch das Herausheben der Sperrzunge aus der Längsnut des Isoliergriffes zu bewirken. Dieser kräftige Fingerdruck muB beim Einschieben des Steckerstiftes in eine Steckbuchse auf - recht erhalten werden. Beim Herausziehen des Steckerstiftes wird die verschiebbare Isolierhülse durch die Federkraft einer Schraubendruckfeder wieder über den Steckerstift geschoben. Dabei gleitet die unter Federdruck stehende Sperrzunge auf der schrägen Gleitfläche leicht über den Vorsprung der Isolierhülse hinweg, bis sie im Ruhezustand wieder dahinter einrastet. Die Rastfläche am Vor - sprung kann senkrecht zur Steckerachse oder auch unter einem kleinen Winkel in der Einführungsrichtung des Steckerstiftes geneigt sein. In beiden Fällen ist es notwendig, daB die Sperr - fläche des Vorsprungs und die daran anstoBende Oberfläche der Sperrzunge annähernd parallel zueinander verlaufen.If the lock can be released by hand according to claim 2, a relatively large force must be required for this, which cannot occur accidentally. This requirement is to be met in a simple manner in the embodiment of the plug pin according to the invention as claimed in claim 3. If the spring force of the leaf spring is dimensioned accordingly, vigorous finger pressure on the central part thereof is required in order to deflect the front part outwards and thereby cause the locking tongue to be lifted out of the longitudinal groove of the insulating handle. This strong finger pressure must be maintained when inserting the plug pin into a socket. When the plug pin is pulled out, the sliding insulating sleeve is pushed over the plug pin again by the spring force of a helical compression spring. The locking tongue, which is under spring pressure, glides slightly over the projection of the insulating sleeve on the inclined sliding surface until it engages behind it again in the idle state. The locking surface on the projection can be inclined perpendicular to the connector axis or at a small angle in the direction of insertion of the connector pin. In both cases, it is necessary that the locking surface of the projection and the abutting surface of the locking tongue run approximately parallel to one another.

Die Ausgestaltung des erfindungsgemäßen Steckerstiftes nach Anspruch 4 bietet den Vorteil, daB das in Form eines Kreissegmentes gebogene Mittelteil der Blattfeder nach der Montage am Isoliergriff unter Vorspannung steht und das Vorderteil fest gegen seine Auflagefläche am Isoliergriff gedrückt wird. Das Befestigungsteil könnte am Isoliergriff angeschraubt, an - genietet oder in anderer Weise befestigt werden. Einfacher und zweckmäBiger ist aber ein in einer Öse einrastendes Befestigungsteil gemäB Anspruch 5. Dabei verhindert das Anstoßen des ver - breiterten Mittelteils oder eines daran angebrachten Vorsprungs an der Öse (Anspruch 6), daB das Befestigungsteil weiter als notwendig in die Öse eingeschoben werden kann. Wenn die Blatt - feder dabei gemäß Anspruch 4 geformt ist, wird das Befestigungsteil durch starke Druckkräfte praktisch spielfrei in der Öse gehalten. Zu diesem Zweck kann das Befestigungsteil auch noch gewölbt oder gebogen sein. Allenfalls noch mögliche seitliche Auslenkungen der Blattfeder werden durch die Maßnahme nach Anspruch 7 mit Sicherheit verhindert. Die dabei verwendeten beiden Vorsprünge am Isoliergriff können auch noch an ihren äub-eren Enden durch einen Steg miteinander verbunden sein. Die Blattfeder kann aus federndem Metall oder Kunststoff be - stehen. Es ist auch denkbar, sie aus mehreren Teilen aus verschiedenen Materialien herzustellen.The design of the connector pin according to the invention according to claim 4 offers the advantage that the central part of the leaf spring, which is curved in the form of a circular segment, is pretensioned after mounting on the insulating handle and the front part is pressed firmly against its contact surface on the insulating handle. The fastening part could be screwed onto the insulating handle, riveted or fastened in some other way. A fastening part which snaps into an eyelet according to claim 5 is simpler and more expedient, however, when the broadened middle part or a projection attached to it prevents the fastening part from being pushed further than necessary into the eyelet. If the leaf spring is shaped according to claim 4, the fastening partly held in the eyelet with virtually no play due to strong pressure forces. For this purpose, the fastening part can also be curved or curved. Any possible lateral deflections of the leaf spring are prevented with certainty by the measure according to claim 7. The two projections used on the insulating handle can also be connected to one another at their outer ends by a web. The leaf spring can be made of resilient metal or plastic. It is also conceivable to manufacture them from several parts from different materials.

Die Figuren zeigen ein Ausführungsbeispiel eines einpoligen Laboratoriumssteckers mit dem erfindungsgemäßen Steckerstift. Fig. 1 ist eine Aufsicht mit aufgeschnittener Befestigungsöse der Blattfeder, Fig. 2 ist ein Längsschnitt.The figures show an embodiment of a single-pole laboratory connector with the connector pin according to the invention. Fig. 1 is a plan view with the fastening eye of the leaf spring cut open, Fig. 2 is a longitudinal section.

Der Steckerstift weist einen Metallschaft 1 auf, auf den eine zylindrische Kontaktfeder 2 mit durch Schlitze gebildeten und korbförmig nach außen gebogenen Stegen 3 aufgeschoben ist. Diese liegt an einem Bund 4 des Schaftes 1 und an der Isolierspitze 5 an, die am vorderen Schaftende angebracht ist. An seinem hinteren Ende weist der Schaft 1 eine Löthülse 6 auf, auf deren vorspringendem Ringwulst eine Metallscheibe 7 aufgelegt ist. Diese liegt in einer Ausnehmung des Isoliergriffes 8, auf dessen Gewindeende ein Gewindeteil 9 einer Isolierhülse lo aufgeschraubt ist, die die Löthülse 6 umschließt. Auf der Metallscheibe 7 steht eine den Steckerschaft 1 umschließende Schraubendruckfeder 11 auf, die mit ihrem anderen Ende an einer Isolierhülse 12 anliegt, die die Kontaktfeder 2 umschließt und mit nach innen ragenden Vorsprüngen 13 eines mehrfach geschlitzten Ringwulstes am Bund 4 des Steckerschaftes 1 anliegt.The plug pin has a metal shaft 1, onto which a cylindrical contact spring 2 with webs 3 formed by slots and bent outward in a basket shape is pushed. This lies on a collar 4 of the shaft 1 and on the insulating tip 5, which is attached to the front end of the shaft. At its rear end, the shaft 1 has a soldering sleeve 6, on the projecting annular bead of which a metal disk 7 is placed. This lies in a recess of the insulating handle 8, on the threaded end of which a threaded part 9 of an insulating sleeve 10 is screwed, which encloses the solder sleeve 6. On the metal disc 7 there is a helical compression spring 11 which surrounds the plug shaft 1, the other end of which rests on an insulating sleeve 12 which surrounds the contact spring 2 and which bears on the collar 4 of the plug shaft 1 with protruding projections 13 of a multiply slotted annular bead.

Die Isolierhülse 12 weist einen Vorsprung 14 auf, der eine zur Steckerspitze hin allmählich abfallende Gleitfläche und am anderen Ende eine zur Steckerachse senkrechte Anschlagfläche aufweist, die an der Sperrzunge 15 einer aus Kunststoff herge - stellten Blattfeder 16 anschlägt. Die Blattfeder 16 besteht aus einem annähernd in Form eines Kreissegmentes gebogenen Mittelteil 17, einem Vorderteil 18 und einem Befestigungsteil 19. Die Längsachse des Befestigungsteils 19 verläuft bei der nichtmontierten Blattfeder 16 parallel zu einer Tangente im hinteren Endpunkt des Kreissegmentes. Nach dem Einschieben des Befestigungsteils 19 in die Öse 2o am Isoliergriff 8 wird das Befestigungsteil 19 gegenüber dem Mittelteil 17 abgewinkelt. Dadurch kommt das Mittelteil 17 unter Vorspannung und drückt das Vorderteil 18 gegen die Auflagefläche des Isoliergriffs 8. Durch starken Fingerdruck auf das Mittelteil 17 wird das Vorderteil 18 mit der Rastzunge 15 nach oben ausgelenkt, sodaB der Vorsprung 14 in der Führungsnut 21 des Isoliergriffs 8 nach innen gleiten kann. Dadurch ist auch die Isolierhülse 12 gegen den Druck der Schraubenfeder 11 in den Isoliergriff hinein verschiebbar, wenn die Kontaktfeder 2 des Steckerstiftes in eine passende Steckbuchse eingeführt wird. Das Befestigungsteil 19 weist einen Längsschlitz 22 auf, sodaB die nach auBen ragenden Nasen 23 beim Einführen des Befestigungsteils in die Öse 2o nach innen gedrückt werden können und hinter der Öse 2o ein - rasten, wenn das Befestigungsteil 19 ganz in die Öse 2o eingeschoben ist. Dann liegen Stirnflächen des verbreiterten Mittelteils 17 an der Befestigungsäse 2o an. Das Vorderteil 18 ist zwischen zwei Vorsprüngen 24 am Isolierteil 6 geführt.The insulating sleeve 12 has a projection 14 which has a sliding surface which gradually drops towards the plug tip and at the other end a stop surface perpendicular to the plug axis points, which strikes the locking tongue 15 of a leaf spring 16 made of plastic. The leaf spring 16 consists of a central part 17 bent approximately in the form of a circular segment, a front part 18 and a fastening part 19. The longitudinal axis of the fastening part 19 in the unmounted leaf spring 16 runs parallel to a tangent in the rear end point of the circular segment. After the fastening part 19 has been inserted into the eyelet 20 on the insulating handle 8, the fastening part 19 is angled relative to the middle part 17. As a result, the middle part 17 comes under prestress and presses the front part 18 against the contact surface of the insulating handle 8. The front part 18 is deflected upward with the latching tongue 15 by strong finger pressure on the middle part 17, so that the projection 14 in the guide groove 21 of the insulating handle 8 follows can slide inside. As a result, the insulating sleeve 12 can also be displaced into the insulating handle against the pressure of the helical spring 11 when the contact spring 2 of the plug pin is inserted into a suitable socket. The fixing member 19 has a longitudinal slot 22, sodaB which can be pressed outwards projecting lugs 23 during insertion of the fastening part in the eyelet 2o inwardly and behind the eyelet 2 o a - rest when the attachment member 19 is fully inserted into the eyelet 2o . Then end faces of the broadened middle part 17 rest against the fastening eye 20. The front part 18 is guided between two projections 24 on the insulating part 6.
