The instrument base (1) is substantially U-shaped in side view, the terminals (6) for the leads, a terminal for an earth lead and other auxiliary contacts being fitted into the side sections (5, 7) forming legs of the U. At the rear of the instrument base (1) there is a device (3/4) for securing it to a rail. The insert (2) is held between the side sections (5, 7) of the instrument base (1) and secured there by detents (42) on either side of the insert which engage behind all the detents (25) in the instrument base (1). There are spring contacts in the web of the instrument base (1) against which rigid contact strips rest when the insert is engaged in the instrument base (1). Towards the front of the instrument base (1), in its side sections (5, 7), there are open gripping recesses (24) through which actuating projections (41) on the resilient wall sections (40) of the casing (31) of the insert (2) carrying the detents (42) are accessible. The design of the combined instrument base (1) and insert (2) makes it possible for the insert (2) be exchanged without having to dismantle the instrument base (1) if, for example, it is damaged or in the case of an overvoltage protecting device if it has been triggered.

Description

Kombination aus Gerätesockel und EinsatzelementCombination of device base and insert element
Die Erfindung betrifft eine Kombination aus Gerätesockel und Einsatzelement.The invention relates to a combination of device base and insert element.
Der Erfindung liegt die Aufgabe zugrunde, im Bedarfsfall das Austauschen des Einsatzelementes, das beispielsweise eine Signaleinrichtung, ein Überspannungsschutz oder ein Meßgerät sein kann, zu vereinfachen.The invention has for its object to simplify the replacement of the insert element, which can be, for example, a signal device, a surge protector or a measuring device, if necessary.
Gelöst wird diese Aufgabe dadurch, daß der Gerätesockel in Seitenansicht im wesentlichen U-förmig ausgebildet ist, daß in den beiden Seitenteilen des Gerätesockels Klemmen für den Anschluß wenigstens einer elektrischen Leitung vorgesehen sind, daß an der Innenseite des den Steg des U bildenden Mit¬ telteils des Gerätesockels Kontakte vorgesehen sind, die mit jeweils einer Klemme in elektrisch leitender Verbindung ste¬ hen, daß am Einsatzelement an dessen der Innenseite des Steges des Gerätesockels zuzukehrender Außenfläche Kontakte vorgese- hen sind, die den Kontakten im Steg des Gerätesockels zugeord¬ net sind, daß an wenigstens einer Seitenwand des Einsatzele¬ mentes die der Innenfläche eines Seitenteils des Gerätesockels zugekehrt ist, ein Rastvorsprung vorgesehen ist, der mit einer Gegenraste am Gerätesockel verrastbar ist.This object is achieved in that the device base is essentially U-shaped in a side view, that terminals are provided in the two side parts of the device base for connecting at least one electrical line, that on the inside of the central part forming the web of the U. contacts of the device base are provided, each of which is in an electrically conductive connection with a clamp, so that contacts are provided on the insert element on its outer surface facing the inside of the web of the device base, which contacts are assigned to the contacts in the web of the device base, that on at least one side wall of the insert element which faces the inner surface of a side part of the device base, a locking projection is provided which can be locked with a counter-locking element on the device base.
Bevorzugte und vorteilhafte Ausführungsformen der Erfindung sind Gegenstand der Unteransprüche.Preferred and advantageous embodiments of the invention are the subject of the dependent claims.
Bei der Erfindung kann das Einsatzelement beispielsweise, wenn es beschädigt ist oder wenn es, wie im Falle einer Überspan¬ nungsschutzeinrichtung, im Überspannungsfall ausgelöst hat, nach dem Lösen der Rastverbindung zwischen Gerätesockel und dem Einsatzelement ohne weiteres abgenommen werden. Das neue Einsatzelement wird einfach am Gerätesockel verrastet. Dieses komfortable Tauschen des Einsatzelementes unterscheidet diese Konstruktion von bestehenden Geräten, welche vorwiegend Kon¬ taktmesser zur Kontaktierung benützen.In the invention, for example, if the insert element is damaged or if it has triggered in the event of an overvoltage protection, as in the case of an overvoltage protection device, it can be easily removed after releasing the latching connection between the device base and the insert element. The new insert element is simply snapped onto the device base. This convenient exchange of the insert element distinguishes this construction from existing devices which mainly use contact knives for contacting.
Weitere Einzelheiten und Merkmale der Erfindung ergeben sich aus der nachstehenden Beschreibung eines Ausführungsbeispieles der Erfindung, nämlich einem als Blockableiter (Überspannungs- schutzvorrichtung) ausgebildeten Einsatzelement, das in einen Gerätesockel austauschbar eingesetzt ist. Es zeigt:Further details and features of the invention result from the following description of an exemplary embodiment of the invention, namely an insert element designed as a block arrester (overvoltage protection device) which is interchangeably inserted into a device base. It shows:

In der folgenden Beschreibung beziehen sich die Angaben "oben", "unten", "vorne", "hinten" auf die in Fig. 1 und 2 gezeigte Ausrichtung des Gerätesockels 1 und des mit diesem verrasteten Einsatzelement 2, in dem beispielsweise eine Über¬ spannungsschutzeinrichtung untergebracht ist. Wenngleich das in den Zeichnungen dargestellte Ausführungsbeispiel mehrpolig ausgeführt ist, kann die Kombination aus Gerätesockel und Einsatzelement auch einpolig, zweipolig usw. sein. Die Zahl der an die Kombination anschließbaren Leitungen ist für die Erfindung jedenfalls nicht wesentlich.In the following description, the information “top”, “bottom”, “front”, “rear” relates to the orientation of the device base 1 shown in FIGS. 1 and 2 and of the insert element 2 locked with it, in which, for example, an overlap voltage protection device is housed. Although the exemplary embodiment shown in the drawings is of multi-pole design, the combination of device base and insert element can also be single-pole, two-pole, etc. In any case, the number of lines that can be connected to the combination is not essential for the invention.
Der Gerätesockel 1 ist im Querschnitt (Fig. 2) im wesentlichen U-förmig ausgebildet, wobei an seiner Rückseite (also "hin¬ ten" ) eine Einrichtung, bestehend aus einem hakenartigen An¬ satz 3 und einem federbelasteten Schnappschieber 4 vorgesehen ist, über welche der Gerätesockel 1, wie an sich bekannt, auf eine beispielsweise in einem Schaltschrank montierte Trag- schiene aufgeschnappt werden kann. In dem in der Fig. 1 und 2 gezeigten Gebrauchslage oberen Schenkel 5 des Gerätesockels 1 sind Anschlußklemmen 6 für drei Außenleiter und eine Anschlußklemme 6 ' für den Null-Leiter untergebracht, deren Ausbildung aus den Fig. 5 und 6 näher ersichtlich ist.The device base 1 is essentially U-shaped in cross section (FIG. 2), a device consisting of a hook-like attachment 3 and a spring-loaded snap slide 4 being provided on its rear side (ie “rear”) which of the device base 1, as is known per se, can be snapped onto a mounting rail, for example mounted in a control cabinet. In the position of use shown in FIGS. 1 and 2, upper leg 5 of the device base 1, connection terminals 6 for three outer conductors and a connection terminal 6 'for the neutral conductor are accommodated, the design of which can be seen in more detail in FIGS. 5 and 6.
In dem in der Gebrauchslage unten liegenden Schenkel 7 des Gerätesockels 1 sind eine Anschlußklemme 8 für die Erdleitung sowie zwei Hilfskontaktklemmen 9 und 10 für einen integrierten Hilfsschalter (Schließer) untergebracht.In the leg 7 of the device base 1 lying at the bottom in the position of use, a connection terminal 8 for the earth line and two auxiliary contact terminals 9 and 10 for an integrated auxiliary switch (make contact) are accommodated.
Von jeder Kontaktklemme 6, 6' und 8 geht ein Kontaktwinkel 11 aus, mit dem ein federnder Kontakt 12 verbunden ist. Die Kon¬ takte 12 ragen von den Schenkeln 5 und 7 in den Steg des Gerä- tesockels 1. Die freien Enden der Kontakte 12 werden von Kon¬ taktfedern 13 nach vorne, also in den Raum zwischen den beiden Schenkeln 5 und 7 des Gerätesockels 1 gedrückt.From each contact terminal 6, 6 'and 8 is a contact angle 11 with which a resilient contact 12 is connected. The contacts 12 protrude from the legs 5 and 7 into the web of the device base 1. The free ends of the contacts 12 are moved forward by contact springs 13, ie into the space between the two legs 5 and 7 of the device base 1 pressed.
Mit der Hilfskontaktklemme 9 ist eine Blattfeder 17 verbunden, die auf noch näher zu beschreibende Weise von einem Betäti¬ gungsstift 37 in Anlage an die Hilfskontaktklemme 10 gebogen werden kann, so daß die Hilfskontaktklemmen 9 und 10 elek¬ trisch leitend miteinander verbunden sind.A leaf spring 17 is connected to the auxiliary contact terminal 9, which can be bent in a manner to be described in more detail below by an actuating pin 37 in contact with the auxiliary contact terminal 10, so that the auxiliary contact terminals 9 and 10 are electrically conductively connected to one another.
Die Kontakte 12 sind durch Öffnungen 18 im nach vorne weisen¬ den Mittelteil 19 des den Gerätesockel 1 innen verschließenden Gehäusedeckels 20 zugänglich (Fig. 3 und 4).The contacts 12 are accessible through openings 18 in the forward-facing middle part 19 of the housing cover 20 which closes the device base 1 on the inside (FIGS. 3 and 4).
In den oben und unten liegenden Wandteilen 21, 22 des Gehäu- sedeckels 20 des Gerätesockels 1 sind Griffmulden 23 und 24 eingeformt, die an ihrer tiefsten Stelle in einen Vorsprung 25, der zum Steg des Gerätesockels 1 hin hinterschnitten aus¬ gebildet ist (Fig. 2), auslaufen.In the upper and lower wall parts 21, 22 of the housing cover 20 of the device base 1, recessed handles 23 and 24 are formed, which at their lowest point are formed in a projection 25 which is undercut towards the web of the device base 1 (FIG. 2), leak.
In dem den unteren Schenkel 7 des Gerätesockels 1 abdeckenden Wandteil des Gehäusedeckels 20 ist in dessen in der Gebrauchs¬ lage des Gerätesockels nach oben weisenden Wandteil ein zu dessen Innenseite offener Schlitz 27 vorgesehen, durch den die Kontaktfeder 17 zu-gänglich ist. Das Einsatzelement 2 besitzt ein Gehäuse aus einem Deckel 30 und einer Wanne 31. Durch den in der Gebrauchsläge hinten liegenden Boden des Gehäusedeckels 30 ragen ein Kontakt 33 und vier Kontakte 34, die durch die Öffnungen 18 im Wandteil 19 des Gehäusedeckels 20 des Gerätesockels 1 an den Kontakten 12 der Kontaktklemme 8 für die Erdleitung, den Kontakten 12 der drei Kontaktklemmen 6 für die Außenleiter und der Kontaktklem¬ me 6' für den Null-Leiter anliegen, wenn das Einsatzelement 2, wie in den Fig. 1 und 2 gezeigt, mit dem Gerätesockel 1 ver- rastet ist.In the wall part of the housing cover 20 covering the lower leg 7 of the device base 1, a slot 27, which is open to the inside and through which the contact spring 17 is accessible, is provided in the wall part which points upward in the position of use of the device base. The insert element 2 has a housing consisting of a cover 30 and a trough 31. A contact 33 and four contacts 34 protrude through the bottom of the housing cover 30, which lies at the back in the position of use the contacts 12 of the contact terminal 8 for the ground line, the contacts 12 of the three contact terminals 6 for the outer conductor and the contact terminal 6 'for the neutral conductor are present when the insert element 2, as shown in FIGS. 1 and 2, with the base 1 is locked.
An einer Wand der Wanne 31 des Einsatzelementes 2 ist eine vorspringende Rippe 35 vorgesehen, die bei in den Gerätesockel 1 eingesetztem Einsatzelement 2 in den Schlitz 27 eingreift, so daß ausschließlich eine lagerichtige Montage des Einsatz¬ elementes 2 am Gerätesockel 1 möglich ist.On a wall of the trough 31 of the insert element 2, a projecting rib 35 is provided, which engages in the slot 27 when the insert element 2 is inserted in the device base 1, so that only a correct mounting of the insert element 2 on the device base 1 is possible.
Durch eine Öffnung 36 im Bereich des oberen Randes der Wanne 31 des Gehäuses des Einsatzelementes 2 ragt der Betätigungs- stift 37, der mit der Kontaktfeder 17 im Gerätesockel 1 auf noch zu beschreibende Art und Weise zusammenwirkt.The actuating pin 37, which interacts with the contact spring 17 in the device base 1 in a manner to be described, projects through an opening 36 in the region of the upper edge of the trough 31 of the housing of the insert element 2.
An der Vorderseite, d.h. dem nach vorne weisenden Boden der Wanne 31 des Gehäuses des Einsatzelementes 2 sind noch zwei durch Kunststoffkuppen verschlossene Öffnungen 38 für Prüfkon¬ takte und ein Sichtfenster 39 für eine Auslöseanzeige 90, 91 vorgesehen.On the front, i.e. The forwardly pointing bottom of the trough 31 of the housing of the insert element 2 is also provided with two openings 38 closed by plastic domes for test contacts and a viewing window 39 for a trigger indicator 90, 91.
An dem Deckel 30 des Gehäuses des Einsatzelementes 2 sind zwei mit diesem einstückig ausgebildete Schnapparme 40 vorgesehen, die in entsprechende Aussparungen in den Seitenwänden der Wanne 31 des Gehäuses des Einsatzelementes 2 greifen. Jeder Schnapparm 40 trägt einen nach außen weisenden Betätigungsvor¬ sprung 41 und zwei ebenfalls nach außen weisende Rastnasen 42, die bei mit dem Gerätesockel 1 verrastetem Einsatzelement 2, wie in Fig. 2 gezeigt, hinter den RastvorSprüngen 25 des Gerä¬ tesockels 1 einrasten. Um das Einsatzelement 2 vom Gerätesok- kel abzunehmen, genügt es von beiden Seiten her auf die Betä¬ tigungsvorsprünge 41 zu drücken, so daß die Vorsprünge 42 von den Rastnasen 25 freikommen, und das Einsatzelement 2 nach vorne (d.h. nach rechts der Fig. 2) vom Gerätesockel 1 abgezo¬ gen werden kann. Dabei sind die Betätigungsvorsprünge 41 dank der Griffmulden 23, 24 gut zugänglich. In diesem Zusammenhang ist darauf hinzuweisen, daß die Griffmulden 23, 24 in der Einbaustellung, d.h. bei in einem Schaltkasten montierter Kombination aus Gerätesockel 1 und Einsatzelement 2 durch eine Blende abgedeckt, d.h. nicht ohne weiteres zugänglich sind. Unbefugtes Hantieren ist damit wenigstens behindert.Provided on the cover 30 of the housing of the insert element 2 are two snap arms 40 which are integrally formed therewith and which engage in corresponding recesses in the side walls of the trough 31 of the housing of the insert element 2. Each snap arm 40 carries an outwardly facing actuation projection 41 and two likewise outwardly facing latching lugs 42, which engage behind the latching projections 25 of the device base 1 when the insert element 2 is locked with the device base 1, as shown in FIG. 2. In order to remove the insert element 2 from the appliance base, it is sufficient to press the actuation projections 41 from both sides, so that the projections 42 come free from the latching lugs 25, and the insert element 2 after can be removed from the device base 1 at the front (ie to the right of FIG. 2). The actuating projections 41 are easily accessible thanks to the recessed handles 23, 24. In this context, it should be pointed out that the recessed handles 23, 24 in the installation position, ie when the combination of device base 1 and insert element 2 is mounted in a switch box, are covered by a panel, ie are not readily accessible. Unauthorized handling is at least hampered.
Um den Deckel 30 des Gehäuses des Einsatzelementes 2 mit der Wanne 31 zu verbinden, sind am Deckel 30 vier Zungen 45 ange¬ formt, die an ihren freien Enden Rastvorsprünge (nicht sicht¬ bar), die nach innen weisen, tragen. Die Zungen 45 sind in Nuten 46 in den Außensseiten der beiden Längswände der Wanne 31 aufgenommen, wobei ihre Rastvorsprünge bei auf die Wanne 31 aufgesetztem Deckel 30 in Löcher 47 eingreifen. Die Löcher 47 sind an den hinteren Enden der Nuten 46 vorgesehen.In order to connect the cover 30 of the housing of the insert element 2 to the trough 31, four tongues 45 are formed on the cover 30, which at their free ends have locking projections (not visible) which point inwards. The tongues 45 are received in grooves 46 in the outer sides of the two longitudinal walls of the tub 31, their latching projections engaging in holes 47 when the lid 30 is placed on the tub 31. The holes 47 are provided at the rear ends of the grooves 46.
