Definitions
- the invention relates to a mechanical lock on a plug connection between an electrical switch and a connector with a pin-shaped extension on one of the two parts to be connected, which engages in a matching recess on the other of the two parts.
- the invention has for its object to form such a mechanical lock between an electrical switch and a connector so that knowledge is required to release the lock that only can have someone who has been familiarized with the matter beforehand, usually an authorized person.
- a mechanical lock according to the generic term according to the invention in that a locking lug protrudes inwards from a side wall of the cutout provided on the switch or on the connecting plug, parallel to the longitudinal axis of the plug connection, for engagement with a locking spring provided on the peg-shaped extension.
- the mechanical locking according to the invention between the electrical switch and the connector has the advantage that the electrical-mechanical connection of the switch and connector can be made in any switch position, but the disconnection is only possible in a very specific switch position. It is particularly advantageous that the locking when manufacturing the Plug connection is carried out completely automatically and requires no additional manipulation. Unlocking requires not only a switch position known only to an authorized person, but also a targeted use of tools, and the principle of locking can be applied not only to switches with rotary movement, but also to switches with linear movement after appropriate adjustment.
- a particularly robust and secure locking of the switch and connector is achieved in a preferred embodiment of the invention in that the projection protruding from the lower part or base of the switch is hollow and cylindrical in shape with a radial recess adjacent to the locking spring, and in that the switching or The axis of rotation of the switch protrudes into the cylindrical extension and, in the area of the lateral recess on the extension, has a lateral groove or flattening as a recess for the engagement of the blocking extension protruding from the locking spring in a certain switching position, in which the recess on the axis of rotation with the recess the cylindrical extension is brought to congruence.
- a particularly secure locking between the switch and the connector is achieved in that the locking projection has a locking surface which engages behind the opposite locking lug and is directed outward at right angles by the locking spring.
- the mechanical locking is also facilitated by the fact that the locking lug protruding laterally into the cutout on the switch or connector has an inclined surface which rises in the direction of insertion of the extension and on which the locking projection forms when the plug connection is made glides along until it engages with its locking surface behind the parallel stop surface on the locking lug.
- the locking lug advantageously has an inclined outer sliding surface with which it slides along the inclined surface of the locking lug when the plug connection is made.
- the locking spring is formed at its free end with a lateral engagement surface for the tool or the screwdriver which projects beyond the locking shoulder. It is advantageous if the locking extension protrudes obliquely inwards from the free end of the locking spring at a distance from the locking shoulder to the opposite side of the locking spring.
- this safety interlock can also be applied to switches with linear movement, such as slide, pressure or plunger switches, if the recess for the engagement of the locking extension opposite the locking projection on the locking spring on a linearly opposite the pin-shaped extension transverse to the longitudinal axis of the plug connection slidable part of the switch is formed.
- the switch 1 is fastened to a support plate 3.
- a support plate 3 From the lower part or base 4 of the switch 1, on which there are also the connection plugs (not shown) for the electrical plug connection, an internally hollow cylindrical extension 5 with a lateral recess 6 protrudes in the longitudinal axis 2a of the plug connection.
- the axis of rotation or switch 7 of the switch 1 extends into the cylindrical extension 5 and has a lateral recess 8 in the form of a groove or flattened portion at a predetermined location, which is formed by rotating the axis of rotation or switch 7 of the switch 1 with the side recess 6 can be brought to congruence on the pin-shaped extension 5.

- a locking extension 17 to the opposite side of the locking spring 9 in the region of the recess 6 protrudes so inwardly that it with a congruent setting of the lateral groove or flattening 8 on the rotation - Or switching axis 7 can engage with the radial recess 6 on the cylindrical extension 5 of the switch 1 in the two overlapping recesses or grooves.
- the locking lug 13 which protrudes into the recess 15 on the connector 2 for the extension 5 of the switch 1, has a rear stop surface 18 for the vertical outward blocking surface 11 on the blocking projection 10 directed to the side by the blocking spring.
- the locking lug 13 is on the housing side wall 14 which is parallel to the longitudinal axis 2a of the plug connection and to the connection plugs of the plug 2, not shown, on the switch 1 or on the plug 2 existing recess 15 is arranged and has an inclined surface 16 for the locking extension in the insertion direction of the peg-shaped extension 5, along which the locking extension 10 slides when the plug connection is made and is deflected until it has its vertical locking surface 11 behind the parallel stop surface 18 the locking lug 13 engages.

- the connector 2 also has an engagement slot 20 on its housing for a pin-shaped tool 21, such as a screwdriver or the like, in order to use it, as shown in FIG. 1, to press the locking projection 10 pointing radially outwards by depressing the locking spring 9 to disengage from the locking lug 13.
- a pin-shaped tool 21 such as a screwdriver or the like
- connection of the connector plug 2 to the base or lower part 4 of the switch 1, which is only schematically indicated, can take place in any switch position if the free end of the locking lug 13 assigned to the locking projection 10 on the locking spring 9 can be moved resiliently or radially, as in the exemplary embodiment of FIG. 4b, is formed so that it is deflected by the inclined surface 12 on the locking projection 10 when the extension 5 is inserted with the locking spring 9.
- the plug connection After the plug connection has been made, it engages behind Locking surface 11 of the locking projection 10, the stop surface 18 on the locking lug 13, and switch 1 and connector 2 are securely locked.
- the switch 1 If the locking is to be released, the switch 1 must first be brought into the position in which the groove or flat 8 on the switching axis 7 faces the locking extension 17 at the end of the locking spring 9.
- the locking projection 10 can be depressed by pressing the locking spring 9 with a pin-shaped tool 21, such as a screwdriver or the like, which has been inserted through the engagement slot 20 or the engagement opening on the connector housing and either on a lateral engagement surface 22 at the free end the locking spring 9 or on the outer sliding surface 12 of the locking projection 10 comes to rest, can be released from the engagement with the locking lug 13.
- the locking spring 9 is moved by the screwdriver towards the covering recess 6 on the extension 5 and the groove or flat 8 on the switching axis 7 to the center until the locking surface 11 of the locking projection 10 is released from the stop surface 18 on the locking lug 13 and the connector 2 can be removed from the switch 1.
- the locking spring 9 can also protrude inwards from the connector 2 in a modified embodiment of the invention, but then the locking lug 13 must be designed for the engagement of the locking projection 10 on the switch 1, while the recess 6 on the extension 5 and the groove or flat 8 on the axis of rotation 7 of the switch 1 must be arranged such that they can be brought into mutual engagement with the locking extension 17 of the locking spring 9 to release the lock.
- the engagement slot 20 or the engagement opening for the screwdriver is then arranged on the housing of the switch instead of on the connector plug 2 in order to release the interlocking between the nested two parts of the switch 1 and the connector plug 2.

Description
Die Erfindung betrifft eine mechanische Verriegelung an einer Steckverbindung zwischen einem elektrischen Schalter und einem Verbindungsstecker mit einem zapfenförmigen Fortsatz an einem der beiden zu verbindenden Teile, der in eine dazu passende Aussparung an dem anderen der beiden Teile eingreift.The invention relates to a mechanical lock on a plug connection between an electrical switch and a connector with a pin-shaped extension on one of the two parts to be connected, which engages in a matching recess on the other of the two parts.
Zur Erhöhung der Funktionssicherheit und zum Schutz gegen Mißbrauch empfiehlt sich bei elektrischen Steckverbindungen von Schaltern eine mechanische Verriegelung des Schalters mit dem Verbindungsstecker. Solche mechanischen Verriegelungen können jedoch in der Regel von jedermann auch ohne besondere Kenntnis der Verriegelungsfunktion mit einfachen Hilfsmitteln gelöst werden, so daß sie praktisch keinen Schutz gegen Mißbrauch darstellen.To increase the functional reliability and to protect against misuse, it is advisable to mechanically lock the switch with the connector for electrical plug connections of switches. However, such mechanical interlocks can generally be solved by anyone even without special knowledge of the interlocking function with simple aids, so that they represent practically no protection against misuse.
Der Erfindung liegt die Aufgabe zugrunde, eine derartige mechanische Verriegelung zwischen einem elektrischen Schalter und einem Verbindungsstecker so auszubilden, daß zum Lösen der Verriegelung Kenntnisse erforderlich sind, die nur jemand haben kann, der mit der Materie vorher vertraut gemacht worden ist, also in der Regel eine dafür autorisierte Person.The invention has for its object to form such a mechanical lock between an electrical switch and a connector so that knowledge is required to release the lock that only can have someone who has been familiarized with the matter beforehand, usually an authorized person.
Diese Aufgabe wird bei einer mechanischen Verriegelung nach dem Gattungsbegriff gemäß der Erfindung dadurch gelöst, daß von einer zu der Längsachse der Steckverbindung parallelen Seitenwand der am Schalter oder am Verbindungsstecker vorhandenen Aussparung eine Sperrnase nach innen hervorsteht für den Eingriff mit einer am zapfenförmigen Fortsatz vorhandenen Sperrfeder, die einen zu der Sperrnase nach außen hervorstehenden Sperransatz und einen nach innen gerichteten Sperrfortsatz aufweist, der in der Lösestellung der Sperrfeder in eine Ausnehmung eingreift, die durch Betätigung des Schalters mit einer Aussparung an dem zapfenförmigen Fortsatz ausgerichtet bzw. zur Deckung gebracht werden kann, und daß an dem Gehäuse des Verbindungssteckers oder des Schalters ein dem freien Ende der Sperrfeder benachbarter Eingriffsschlitz für ein stiftförmiges Werkzeug, wie ein Schraubendreher oder dergleichen, vorgesehen ist, durch das der Sperransatz nur in derjenigen Stellung des Schalters, in der der Sperrfortsatz der Sperrfeder der Ausnehmung an dem zapfenförmigen Fortsatz für einen Sperreingriff gegenübersteht, aus der Verriegelungsstellung mit der Sperrnase lösbar ist, so daß Schalter und Verbindungsstecker auseinandergezogen und voneinander getrennt werden können.This object is achieved with a mechanical lock according to the generic term according to the invention in that a locking lug protrudes inwards from a side wall of the cutout provided on the switch or on the connecting plug, parallel to the longitudinal axis of the plug connection, for engagement with a locking spring provided on the peg-shaped extension. which has a locking projection protruding outward to the locking lug and an inward locking extension which engages in the release position of the locking spring in a recess which can be aligned or made to cover by actuating the switch with a recess on the peg-shaped extension, and that on the housing of the connector or the switch an adjacent the free end of the locking spring engagement slot for a pen-shaped tool, such as a screwdriver or the like, is provided by which the locking approach only in that position of the Scha lters, in which the locking extension of the locking spring of the recess on the peg-shaped extension is opposite for a locking engagement, can be released from the locking position with the locking lug, so that switches and connecting plugs can be pulled apart and separated from one another.
Die erfindungsgemäße mechanische Verriegelung zwischen elektrischem Schalter und Verbindungsstecker hat den Vorteil, daß die elektrisch-mechanische Verbindung von Schalter und Verbindungsstecker in beliebiger Schalterstellung erfolgen kann, die Trennung der Verbindung aber nur in einer ganz bestimmten Schalterposition möglich ist. Von besonderem Vorteil ist dabei, daß die Verriegelung beim Herstellen der Steckverbindung völlig automatisch erfolgt und keine zusätzlichen Manipulationen erfordert. Zur Entriegelung ist nicht nur eine ausschließlich einer autorisierten Person bekannte Schalterposition, sondern zusätzlich ein gezielter Werkzeugeinsatz erforderlich, und das Prinzip der Verriegelung kann nicht nur bei Schaltern mit Drehbewegung, sondern nach entsprechender Anpassung auch bei Schaltern mit linearer Bewegung angewandt werden.The mechanical locking according to the invention between the electrical switch and the connector has the advantage that the electrical-mechanical connection of the switch and connector can be made in any switch position, but the disconnection is only possible in a very specific switch position. It is particularly advantageous that the locking when manufacturing the Plug connection is carried out completely automatically and requires no additional manipulation. Unlocking requires not only a switch position known only to an authorized person, but also a targeted use of tools, and the principle of locking can be applied not only to switches with rotary movement, but also to switches with linear movement after appropriate adjustment.
Eine besonders robuste und sichere Verriegelung von Schalter und Verbindungsstecker wird bei einer bevorzugten Ausführungsform der Erfindung dadurch erreicht, daß der vom Unterteil oder Sockel des Schalters hervorstehende Fortsatz innen hohl und zylinderförmig mit einer der Sperrfeder benachbarten radialen Aussparung ausgebildet ist, und daß die Schalt- oder Drehachse des Schalters in den zylinderförmigen Fortsatz hineinragt und im Bereich der seitlichen Aussparung an dem Fortsatz eine seitliche Nut oder Abflachung als Ausnehmung für den Eingriff des von der Sperrfeder hervorstehenden Sperrfortsatzes in einer bestimmten Schaltstellung aufweist, in der die Ausnehmung an der Drehachse mit der Aussparung an dem zylinderförmigen Fortsatz zur Deckung gebracht ist.A particularly robust and secure locking of the switch and connector is achieved in a preferred embodiment of the invention in that the projection protruding from the lower part or base of the switch is hollow and cylindrical in shape with a radial recess adjacent to the locking spring, and in that the switching or The axis of rotation of the switch protrudes into the cylindrical extension and, in the area of the lateral recess on the extension, has a lateral groove or flattening as a recess for the engagement of the blocking extension protruding from the locking spring in a certain switching position, in which the recess on the axis of rotation with the recess the cylindrical extension is brought to congruence.
Eine besonders sichere Verriegelung zwischen Schalter und Verbindungsstecker wird dabei dadurch erreicht, daß der Sperransatz eine die gegenüberliegende Sperrnase hintergreifende, von der Sperrfeder rechtwinklig nach außen gerichtete Sperrfläche aufweist.A particularly secure locking between the switch and the connector is achieved in that the locking projection has a locking surface which engages behind the opposite locking lug and is directed outward at right angles by the locking spring.
Erleichtert wird die mechanische Verriegelung auch noch dadurch, daß die in die Aussparung am Schalter oder Verbindungsstecker seitlich hineinragende Sperrnase eine in Einschubrichtung des Fortsatzes ansteigende Schrägfläche aufweist, an der der Sperransatz beim Herstellen der Steckverbindung entlanggleitet, bis er mit seiner Sperrfläche die dazu parallele Anschlagfläche an der Sperrnase sperrend hintergreift. Der Sperransatz weist dabei vorteilhaft eine schräge außenliegende Gleitfläche auf, mit der er beim Herstellen der Steckverbindung an der Schrägfläche der Sperrnase entlanggleitet.The mechanical locking is also facilitated by the fact that the locking lug protruding laterally into the cutout on the switch or connector has an inclined surface which rises in the direction of insertion of the extension and on which the locking projection forms when the plug connection is made glides along until it engages with its locking surface behind the parallel stop surface on the locking lug. The locking lug advantageously has an inclined outer sliding surface with which it slides along the inclined surface of the locking lug when the plug connection is made.
Eine unproblematische und sichere Entriegelung der Steckverbindung wird ferner dadurch ermöglicht, daß die Sperrfeder an ihrem freien Ende mit einer über den Sperransatz endseitig hervorstehenden seitlichen Angriffsfläche für das Werkzeug oder den Schraubendreher ausgebildet ist. Von Vorteil ist es dabei, wenn der Sperrfortsatz vom freien Ende der Sperrfeder im Abstand von dem Sperransatz zu der entgegengesetzten Seite der Sperrfeder schräg nach innen hervorsteht.An unproblematic and safe unlocking of the plug connection is also made possible in that the locking spring is formed at its free end with a lateral engagement surface for the tool or the screwdriver which projects beyond the locking shoulder. It is advantageous if the locking extension protrudes obliquely inwards from the free end of the locking spring at a distance from the locking shoulder to the opposite side of the locking spring.
Ferner kann das Prinzip dieser Sicherheitsverriegelung auch bei Schaltern mit linearer Bewegung, wie Schiebe-, Druck- oder Stößelschaltern angewandt werden, wenn die Aussparung für den Eingriff des dem Sperransatz an der Sperrfeder gegenüberliegenden Sperrfortsatzes an einem gegenüber dem zapfenförmigen Fortsatz quer zur Längsachse der Steckverbindung linear verschiebbaren Teil des Schalters ausgebildet ist.Furthermore, the principle of this safety interlock can also be applied to switches with linear movement, such as slide, pressure or plunger switches, if the recess for the engagement of the locking extension opposite the locking projection on the locking spring on a linearly opposite the pin-shaped extension transverse to the longitudinal axis of the plug connection slidable part of the switch is formed.

Bei dem in der Zeichnung schematisch dargestellten Ausführungsbeispiel einer mechanischen Verriegelung zwischen einem elektrischen Schalter 1 und einem Verbindungsstecker 2 ist der Schalter 1 an einer Tragplatte 3 befestigt. Vom Unterteil oder Sockel 4 des Schalters 1, an dem sich auch die nicht dargestellten Anschlußstecker für die elektrische Steckverbindung befinden, steht in der Längsachse 2a der Steckverbindung ein innen hohler zylinderförmiger Fortsatz 5 mit einer seitlichen Aussparung 6 hervor. Die Dreh- oder Schaltachse 7 des Schalters 1 reicht in den zylinderförmigen Fortsatz 5 hinein und hat an einer vorbestimmten Stelle eine seitliche Ausnehmung 8 in Form einer Nut oder Abflachung, die durch Drehen der Dreh- oder Schaltachse 7 des Schalters 1 mit der seitlichen Aussparung 6 an dem zapfenförmigen Fortsatz 5 zur Deckung gebracht werden kann. Statt mit einer solchen Nut oder Abflachung kann die Dreh- oder Schaltachse 7 an dieser Stelle auch exzentrisch ausgebildet sein.In the exemplary embodiment of a mechanical interlock shown schematically in the drawing between an
Mit dem Schaltersockel 4 ist außerdem eine etwa parallel zu dem Fortsatz 5 und zur Längsachse 2a der Steckverbindung hervorstehende Sperrfeder 9 mit einem seitlichen Sperransatz 10 verbunden, der eine Sperrfläche 11 und eine außenliegende schräge Gleitfläche 12 aufweist, mit der er beim Herstellen der Steckverbindung an einer Sperrnase 13 entlanggleitet, die von der Gehäuseseitenwand 14 des Verbindungssteckers 2 in die Aussparung 15 für den Fortsatz 5 radial nach innen hervorsteht und eine in Einschubrichtung des Schalterfortsatzes 5 ansteigende Schrägfläche 16 aufweist.With the
Vom freien Ende der Sperrfeder 9 steht außerdem im Abstand von dem Sperransatz 10 ein Sperrfortsatz 17 zu der entgegengesetzten Seite der Sperrfeder 9 im Bereich der Aussparung 6 derart schräg nach innen hervor, daß er bei einer deckungsgleichen Einstellung der seitlichen Nut oder Abflachung 8 an der Dreh- oder Schaltachse 7 mit der radialen Aussparung 6 an dem zylinderförmigen Fortsatz 5 des Schalters 1 in die beiden sich deckenden Aussparungen oder Nuten eingreifen kann.From the free end of the
Wie in den Schnittdarstellungen von Fig. 1, Fig. 4a und Fig. 4b zu erkennen ist, weist die Sperrnase 13, die in die am Verbindungsstecker 2 vorhandene Aussparung 15 für den Fortsatz 5 des Schalters 1 hineinragt, eine rückwärtige Anschlagfläche 18 für die senkrecht nach außen gerichtete Sperrfläche 11 an dem von der Sperrfeder zur Seite gerichteten Sperransatz 10 auf. Die Sperrnase 13 ist an der zu der Längsachse 2a der Steckverbindung und zu den nicht gezeigten Anschlußsteckern des Verbindungssteckers 2 parallelen Gehäuseseitenwand 14 der am Schalter 1 oder am Verbindungsstecker 2 vorhandenen Aussparung 15 angeordnet und weist eine in Einschubrichtung des zapfenförmigen Fortsatzes 5 ansteigende Schrägfläche 16 für den Sperransatz auf, an der der Sperransatz 10 beim Herstellen der Steckverbindung entlanggleitet und solange ausgelenkt wird, bis er mit seiner senkrechten Sperrfläche 11 hinter der dazu parallelen Anschlagfläche 18 der Sperrnase 13 einrastet. Die Sperrnase 13 kann, wie in Fig. 1 und Fig. 4a gezeigt ist, mit ihrem freien Ende federnd ausgebildet sein.As can be seen in the sectional views of FIGS. 1, 4a and 4b, the
Der Verbindungsstecker 2 weist außerdem an seinem Gehäuse einen Eingriffsschlitz 20 für ein stiftförmiges Werkzeug 21, wie ein Schraubendreher oder dergleichen, auf, um mit dessen Hilfe, wie in Fig. 1 gezeigt ist, den radial nach außen weisenden Sperransatz 10 durch Niederdrücken der Sperrfeder 9 außer Eingriff mit der Sperrnase 13 zu bringen. Dies ist nur in einer bestimmten Stellung des Schalters 1 möglich, in der der Sperrfortsatz 17 der Sperrfeder 9 zugleich in die Aussparung 6 an dem zapfenförmigen Fortsatz 5 und in die damit deckungsgleiche Nut oder Abflachung 8 an der Schaltachse 7 eingreifen kann, so daß die Sperrfeder 13 aus der Verriegelungsstellung von Fig. 1 und Fig. 4a mit der Sperrnase 13 gelöst werden kann und Schalter 1 und Verbindungsstecker 2 voneinander getrennt werden können.The
Die Verbindung des Verbindungssteckers 2 mit dem Sockel oder Unterteil 4 des nur schematisch angedeuteten Schalters 1 kann in jeder Schalterposition erfolgen, wenn die dem Sperransatz 10 an der Sperrfeder 9 zugeordnete Sperrnase 13 mit ihrem freien Ende federnd oder radial verschiebbar, wie im Ausführungsbeispiel von Fig. 4b gezeigt, ausgebildet ist, so daß sie beim Einschieben des Fortsatzes 5 mit der Sperrfeder 9 durch die Schrägfläche 12 am Sperransatz 10 ausgelenkt wird. Nach Herstellung der Steckverbindung hintergreift die Sperrfläche 11 des Sperransatzes 10 die Anschlagfläche 18 an der Sperrnase 13, und Schalter 1 und Verbindungsstecker 2 sind sicher verriegelt.The connection of the connector plug 2 to the base or
Soll die Verriegelung gelöst werden, so muß der Schalter 1 erst in die Stellung gebracht werden, in der die Nut oder Abflachung 8 an der Schaltachse 7 dem Sperrfortsatz 17 am Ende der Sperrfeder 9 gegenübersteht.If the locking is to be released, the
Ist diese Stellung erreicht, so kann der Sperransatz 10 durch Niederdrücken der Sperrfeder 9 mit einem stiftförmigen Werkzeug 21, wie ein Schraubendreher oder dergleichen, das durch den Eingriffsschlitz 20 oder die Eingriffsöffnung am Steckergehäuse eingeführt worden ist und entweder an einer seitlichen Angriffsfläche 22 am freien Ende der Sperrfeder 9 oder an der außenliegenden Gleitfläche 12 des Sperransatzes 10 zur Anlage kommt, aus dem Eingriff mit der Sperrnase 13 gelöst werden. Die Sperrfeder 9 wird dabei durch den Schraubendreher in Richtung auf die sich deckende Aussparung 6 an dem Fortsatz 5 und die Nut oder Abflachung 8 an der Schaltachse 7 zur Mitte bewegt, bis die Sperrfläche 11 des Sperransatzes 10 von der Anschlagfläche 18 an der Sperrnase 13 freikommt und der Verbindungsstecker 2 von dem Schalter 1 abgezogen werden kann.Once this position has been reached, the
Statt vom Schalter 1 kann die Sperrfeder 9 bei einer abgewandelten Ausführungsform der Erfindung auch von dem Verbindungsstecker 2 nach innen hervorstehen, wobei dann allerdings die Sperrnase 13 für den Eingriff des Sperransatzes 10 am Schalter 1 ausgebildet sein muß, während die Aussparung 6 an dem Fortsatz 5 und die Nut oder Abflachung 8 an der Drehachse 7 des Schalters 1 derart angeordnet sein müssen, daß sie mit dem Sperrfortsatz 17 der Sperrfeder 9 zum Lösen der Verriegelung in gegenseitigen Eingriff gebracht werden können. Entsprechend ist dann auch der Eingriffsschlitz 20 oder die Eingriffsöffnung für den Schraubendreher statt am Verbindungsstecker 2 am Gehäuse des Schalter angeordnet, um die Verriegelung zwischen den ineinandergesteckten beiden Teilen des Schalters 1 und des Verbindungssteckers 2 zu lösen.Instead of the
Das Prinzip dieser Sicherheitsverriegelung kann ebenso wie bei Schaltern mit Drehbewegung nach entsprechender Anpassung auch bei Schaltern mit linearer Bewegung angewandt werden, wobei dann die Aussparung 6 für den Eingriff des dem Sperransatz 10 an der Sperrfeder 9 gegenüberliegenden Sperrfortsatzes 17 an einem gegenüber dem zapfenförmigen Fortsatz 5 quer zur Längsachse 2a der Steckverbindung linear verschiebbaren Teil des Schalters 1 ausgebildet ist.The principle of this safety interlock can be applied to switches with linear movement as well as with switches with rotary movement after corresponding adjustment, the

- Mechanical locking at a plug connection between an electric switch (1) and a plug connector (2) with a peg-type extension (5) on one of the two parts to be connected which engages into a matching recess (15) on the other of the two parts, characterized in that a locking lug projects (13) inwards from a side wall (14), parallel to the longitudinal axis (2a) of the plug connection, of the recess (15) on the switch (1) or on the plug connector (2) so as to engage with a locking spring (9), located on the peg-type extension (5), which has a locking projection (10) which projects outwards towards the locking lug (13) and a locking extension (17), directed inwards, which, when the locking spring (9) is in the released position, engages into a chase (8) which can be aligned or brought to coincidence with a recess (6) on the peg-type extension (5) by actuation of the switch (1), and in that on the housing of the plug connector (2) or of the switch (1) there is an insertion slot (20), adjacent to the free end of the locking spring (9), for a pencil-type tool (21) such as a screwdriver or similar device by means of which the locking projection (10) can only be released from the locking position with the locking lug (13) when the switch (1) is in the position in which the locking extension (17) of the locking spring (9) faces the chase (8) on the peg-type extension (5) for a locking engagement, enabling the switch (1) and plug connector (2) to be drawn apart and separated from each other.
- Mechanical locking according to Claim 1, characterized in that the extension (5) projecting from the bottom part or base (4) of the switch (1) is internally hollow and cylindrical in form with a radial recess (6) adjacent to the locking spring (9) and in that the switching or rotary shaft (7) of the switch (1) projects into the cylindrical extension (5) and, in the region of the lateral recess (6) on the extension (5), possesses a lateral groove or flattening as a chase (8) for the engagement of the locking extension (17) projecting from the locking spring (9) in a defined switching position in which the chase (8) on the rotary shaft (7) is brought to coincidence with the recess (6) on the cylindrical extension (5).
- Mechanical locking according to either of Claims 1 or 2, characterized in that the locking projection (10) includes a locking face (11), directed outwards at right angles from the locking spring (9), which engages behind the opposing locking lug (13).
- Mechanical locking according to any one of Claims 1 to 3, characterized in that the locking lug (13) which projects laterally into the recess (15) on the switch (1) or plug connector (2) includes an oblique face (16), ascending in the direction of insertion of the extension (5), along which the locking projection (10) slides in the making of the plug connection until its locking face (11) engages behind the parallel stop face (18) on the locking lug (13), effecting a lock.
- Mechanical locking according to any one of Claims 1 to 4, characterized in that the locking projection (10) includes an outer oblique sliding face (12) by means of which it slides along the oblique face (16) of the locking lug (13) in the making of the plug connection.
- Mechanical locking according to any one of Claims 1 to 5, characterized in that the free end of the locking spring (9) is formed with a lateral application face (22) for the tool (21) or screwdriver projecting endwise over the locking projection (10).
- Mechanical locking according to any one of Claims 1 to 6, characterized in that the locking extension (17) projects obliquely inwards from the free end of the locking spring (9) at a distance from the locking projection (10) on the opposite side of the locking spring (9).
- Mechanical locking according to Claim 1, characterized in that the recess (6) for the engagement of the locking extension (17) opposite to the locking projection (10) on the locking spring (9) is formed on a part of the switch (1) capable of linear displacement across the longitudinal axis (2a) of the plug connection towards the peg-type extension (5).
