Description

BACKGROUND OF THE INVENTION FIELD OF THE INVENTION

The invention relates to a separation mechanism for a socket or a plug, in particular a three-phase connection. The invention further relates to a socket and a plug, in particular a three-phase connection, with a separation mechanism.

STATE OF THE ART

Electrical connections between two devices are known to be made via connectors, which are plugged into a corresponding socket, wherein an electrical contact is made. To disconnect the connector, the plug is pulled out of the socket. However, separation mechanisms are known from the prior art, by means of which the connector can be separated.

Such is the publication of the international patent application WO 2016/043418 A1 a plug is known which has a separating mechanism which comprises a squeezer and a lever. The lever is disposed in a recess of the plug and has a curved contact surface, which faces a curved contact surface of a male ejector arranged in the plug. When the lever is pivoted into the recess, the contact surface of the lever slides on the contact surface of the ejector. The ejector is moved out of the front surface of the plug and presses against the socket, which plug and socket are finally separated from each other. If the plug is plugged into a socket again, the ejector is pushed into the socket, causing the lever upright again.

Plugs and sockets for cables, which carry high currents, are relatively massive and they have quite a lot of power for separating a Plug connection required so that the connector can not be accidentally released. For such connectors also serving as a separation aid separation mechanism from the prior art is known.

The Utility Model DE 20 2005 006 236 U1 discloses various embodiments of a disconnect mechanism for power connectors, the receptacle having a disconnect mechanism including an actuation lever and thrust members. The operating lever exerts when folding over the pushers directed in the direction of the plug thrust on the spacer ring of the plug, so that the plug detaches from the socket. The actuating lever is mounted on opposite sides of the socket to the housing and connected to both sides also arranged on the socket push elements.

In these separation mechanisms, however, the movement of the ejector or the push element is always accompanied by a movement of the lever, so that even when inserting the plug into a socket, the lever is moved.

DISCLOSURE OF THE INVENTION OBJECT OF THE INVENTION

Object of the present invention is to provide a separation mechanism with a lever for a connector, in which the existing squeeze can be moved independently of the lever in their original positions.

TECHNICAL SOLUTION

This object is achieved by a separation mechanism with the features of claim 1 or 10 and a socket or a plug with the features of claim 15. Advantageous embodiments are the subject of the dependent claims.

According to the invention it is provided that the separation mechanism comprises a release element associated with the coupling element, which is arranged on a pivot axis of the lever and has at least one projection, and the ejector has a groove or recess into which protrudes the projection of the ejector at a certain lever position ,

Accordingly, the separation mechanism according to the invention comprises at least one squeezer and at least one coupling element. In this case, a squeezer may be present, which is arranged, for example, centrally on the front surface of a socket or a plug. A coupling element is arranged on the pivot axis of the lever, which rotates upon pivoting of the lever. In this case, the projection of the coupling element comes to rest on the ejector, so that the ejector is extended by the pivoting of the lever and the associated rotation of the coupling element. When the lever has reached a certain lever position, the projection of the coupling element protrudes into the recess or groove of the ejector, so that on the one hand, the squeeze is not extended and on the other hand, the squeezer can return to its original position, without it for this return requires a movement of the lever.

Preferably, the coupling element has a plurality of projections which are distributed around the circumference thereof.

Furthermore, a respective squeezer and a coupling element are preferably arranged on opposite sides of the socket or the plug, wherein in each case a coupling element cooperates with a squeezer. In this embodiment, the force for disconnecting the socket and plug is exerted by two squeeze, whereby tilting of the plug in the socket during the separation process can be avoided. Furthermore, the ejectors can be integrated into a separable from the socket or the plug separation mechanism. Such a separation mechanism can be attached, for example by means of a tensionable steel strip to a socket or a plug, so that they can also be retrofitted with a separation mechanism according to the invention.

In an advantageous embodiment, a restoring element is connected to each squeezer, wherein the restoring force of the restoring element acts against the extension of the squeezer. By the restoring element, the ejectors automatically return to their starting position as soon as the projection of the respective coupling element projects into the recess or groove of the ejector. The restoring element may simply be a helical spring which is connected at one end to a squeezer and at the other end to the socket or the plug.

Whether the ejector be extended in a forward pivoting of the lever or in a reverse pivoting of the lever, depends on the design of the squeezer and the coupling elements and on the orientation of the coupling elements. In principle, various configurations are possible, but it is preferably provided that the squeezer be extended when the lever is pivoted away from the component corresponding to the socket or the plug. If the separating mechanism is integrated into or arranged on a socket, the ejectors are extended when the lever is pivoted away from the plug. If, however, the separation mechanism integrated into a plug or arranged on this, an extension of the ejector takes place at a pivoting of the lever away from the socket. This has the advantage that during the extension of the squeezer at the same time a present in some connectors lid can be raised. For this purpose, one or more cover lifters can be arranged on the lever. It can also be provided that the lever has parallel leg connected by a handle, wherein then on the inner surface of each leg one (or more) lid lifters are arranged.

Such a cover is for example in IEC 60309 connectors, such as three-phase connectors available. IEC 60309 is an international standard for connectors for industrial applications. In this case, either the socket or the plug has a lid which is pivotally mounted on the socket or the plug and is folded by the restoring force of a spring on the front surface of the socket or the plug, so that the lid must first be lifted against the spring force, around a plug connection to be able to produce. The corresponding component (plug or socket) has a nose on which the lid rests when manufactured connector, wherein the edge of the lid engages behind the nose. The nose prevents the two components from being separated without the lid having been raised previously, and thus accidental disconnection of the connector, such as someone stumbling over the power line, is precluded. However, this interaction of the lid with the nose complicates the separation of the connector, since the lid must be pushed upwards and at the same time pulled both the socket and the plug. The lid lifter invention greatly simplify the separation process, since by moving the lever, the lid is lifted simultaneously over the nose.

The projection of the coupling element extends in some embodiments of the separation mechanism according to the invention in the radial direction of the coupling element and in others in the axial direction. Both embodiments are possible. In the axial direction, the direction of the axis of rotation of a coupling element and in the radial direction is understood a direction perpendicular to the axial direction.

For example, it may be provided that the projection extends in the radial direction and abuts a contact surface of a presser when the lever is pivoted, so that the ejector is extended during the forward movement of the projection during rotation of the coupling element until the projection in the recess or groove of the ejector protrudes. Once the projection is no longer applied to the contact surface, the ejector can return to its original position.

Furthermore, it can be provided that at least one depression corresponding to the at least one projection of the coupling element is formed on a boundary surface of the recess or groove of the ejector. In this case, engages in a pivoting of the lever, the projection of the coupling element in the recess of the ejector. Preferably, the coupling element on a plurality of projections which extend on both sides of the coupling element, so that the outer edge of the coupling element has a broken on two opposite sides toothing. Accordingly, have two Boundary surfaces of the ejector in each case a plurality of depressions, in which engage the projections, so that the coupling element and the squeezer are interlocked with each other. When pivoting the lever in one direction, the coupling element rotates, the co-rotating projections extend through their engagement in the wells the squeezer. At a certain lever position the projections protrude into the recess or groove of the ejector and no longer in the wells, so that the squeezer is not extended and can return to its original position.

If, on the other hand, one (or more) projection extending in the axial direction of the coupling element is present on the coupling element, this projection extends laterally into the ejector. Upon pivoting of the lever and the concomitant rotation of the coupling element of the projection comes to rest against a contact surface of the ejector, so that the ejector is extended during the forward movement of the projection during rotation of the coupling element until the projection projects into the recess or groove, so the ejector is not extended and can return to its original position. Preferably, two or three projections are arranged distributed at the same distance on a coupling element, since the coupling element rotates in one direction only when the pivoting of the lever.

That the coupling element is rotated only in a preferred pivoting direction of the lever, can be achieved by a pawl wheel associated with each coupling element, the pawl wheel consists of two discs, of which only one is fixedly connected to the coupling element. Of the two mutually rotatable discs, a first disc has at least one elevation extending in the axial direction and a second disc has at least one opening corresponding to the elevation into which the elevation can engage. The survey has one of the other disc facing inclined surface, so that the survey extends increasingly along its length in the opening. This allows the survey slide at a certain rotational direction over the edge of the opening, but abuts in the opposite direction of rotation to the opposite edge of the opening, causing a rotation of the first disc is blocked relative to the second disc in this opposite direction of rotation.

Alternatively, the projection of the coupling element in the axial direction can be elastically deflected. Under an elastic deflection is understood here that the deflection takes place against a restoring force, wherein the restoring force can put the projection back to its original position. The restoring force can be the result of elastic deformation of the projection itself. For example, the coupling element may have an incision extending over a part of the circumference of the coupling element, wherein an edge region delimited by the incision extends in the axial direction. In this embodiment of the coupling element, the projection can be deflected elastically in the axial direction against a restoring force exerted by the edge region itself due to its material properties.

But it is also possible that the restoring force resulting from the deformation of a separate component, such as a coil spring. The projection is then mounted correspondingly movable.

The present invention also relates to a separation mechanism which is not integrated into a female connector or a male connector but is arranged on a female connector or a male connector. For this purpose, in one embodiment, the separating mechanism comprises a cross-sectionally open carrier on which the lever and for each squeezer a receiving space is arranged, each squeezer is arranged in a receiving space, and wherein two end portions of the carrier are connected to each other via a fastening device.

For round in cross-section sockets or plugs, the carrier in cross-section substantially a circular arc shape (C-shape), so that the carrier surrounds the circumference of a socket or a plug partially. The fastening device is arranged between the two mutually facing end portions of the carrier and serves to attach the carrier to the socket or the plug. The fastening device may comprise, for example, a steel strip and a clamping element arranged on the carrier, wherein the carrier is fastened to the socket or the plug in that over the steel strip and by means of the tensioning element on the two end portions a tensile force is applied.

The invention further relates to a disconnecting mechanism for a socket or a plug, the Ausdrücker are not actuated by a lever. This alternative embodiment of a separation mechanism is characterized in that a rotatable sleeve is arranged on a socket or a plug, which surrounds the socket or the plug and has a thread on an inner surface, and the socket or the plug at least one squeezer with a in includes the threaded engaging portion. In this case, the actuation of the ejector does not take place via a lever, but via a sleeve which is rotatably mounted on a plug socket or a plug, and surrounds the plug socket or the plug. The sleeve may be corrugated on its outer surface or may have spaced projections so that it can be rotated by a user without slipping on its outer surface. On an inner surface of the sleeve, a thread is formed, the pitch of which can be selected depending on the angle at which the sleeve is to be rotated in order to effect a complete extension of the ejector. For strong connectors, ie those in which a comparatively large force must be applied to disconnect the connector, a low pitch of the thread is advantageous. A portion of the ejector engages the thread of the sleeve, whereby the force exerted by a user on the sleeve force is transmitted to the ejector and can extend this.

Preferably, in turn, a squeezer is arranged on opposite sides of the socket or the plug.

It may further be provided that the thread is interrupted by at least one unthreaded area. Such areas allow the ejectors to return to their original positions without having to rotate the sleeve in the opposite direction.

In a particularly preferred embodiment, in turn, a return element is connected to each squeezer, wherein the restoring force of the return element acts against the extension of the squeezer. By such a return element, which may be formed as connected to both a squeezer and the socket or the plug coil spring, the squeeze are automatically transferred to their original positions as soon as the squeeze with the thread-free areas of the sleeve.

In all the aforementioned embodiments of the separation mechanism according to the invention, the ejectors may have on a front side a tab which is adapted to engage in the gap between a socket and a plug.

EMBODIMENTS

Fig. 1 shows a perspective view of a socket 1 with a first embodiment of the separation mechanism according to the invention, which is integrated into the socket 1. The separating mechanism comprises a lever 2, which has two legs 21 and a handle 22 connecting the two legs 21. The two legs 21 are mounted on opposite sides of the socket 1 via a respective axis 3. The axes 3 extend into the socket 1. The socket 1 has at these opposite sides in each case a receiving space 4, in each of which a squeezer 5 is arranged. The ejectors have at their front ends in each case a tab 6, which is intended to engage in the gap between the socket 1 and a plug. The socket 1 further comprises a cover 7 which is connected via a hinge 71 to the socket 1 and is pressed by a spring on the front surface of the socket 1, so that the cover 7 can be folded up only against the spring force of this spring.

Upon pivoting of the lever 2, the axes rotate 3. The rotational movement of the axles 3 is transmitted via arranged in the receiving spaces 4 coupling elements to the squeezer 5, that they are extended. The squeeze 5 return automatically at a certain orientation of the coupling elements back to their original positions. A rotation of the axes 3 in a pivoting of the lever 2 in the opposite direction has no influence on the squeezer. 5

In the embodiment according to Fig. 1 a plug connection between the socket 1 and a plugged into this on the front surface connector is achieved in that the lever 2 is pivoted to the plug, said pivoting, however, has no effect on the squeezer 5. Subsequently, the lever 2 is pivoted in the opposite direction to this in its in Fig. 1 to reset the initial position shown. Only the ejector 5 are extended and the plug connection between socket 1 and plug disconnected. When the lever 2 reaches its home position, the ejectors 5 automatically return to the receiving spaces 4 due to a tensile force acting on them and being exerted by a return element.

Fig. 2a to Fig. 2e show an embodiment of the first embodiment. The separating mechanism is integrated into the socket 1 and comprises two ejectors 10, which are each connected to the socket 1 via a formed as a spiral spring 11 return element with the socket 1. The ejectors 10 have a recess 101 extending in the longitudinal direction thereof. The separating mechanism further comprises a coupling element 102 associated with each ejector 10 and having three projections 1021 which are distributed at an angle difference of 120 ° at the circumference of the coupling element 102. The coupling elements 102 thus have a star shape with serrated projections 1021, wherein the projections 1021 each have a curved side surface and a straight side surface. The coupling elements 102 are arranged on the axes 3 and are in a certain direction (to the right in. In a pivoting of the lever 2 in a certain direction Fig. 2a to 2e ) turned. For selective rotation of the coupling elements 102, the separating mechanism further comprises ratchet wheels 103, wherein each coupling element 102 is associated with a ratchet wheel 103. Each ratchet wheel 103 consists of two discs, of which only one with the respective coupling element 102 and the other with the respective leg 21 of the lever 2 is firmly connected.

Fig. 2e shows two possible embodiments of a ratchet wheel 103. In a first embodiment, a disc 1031 has two openings 1032 and the other disc 1034 has two elevations 1034, which can engage in the openings 1033. This embodiment can be applied in the case that the coupling elements 102 have only two offset by an angular difference of 180 ° projections 1021. The protrusions 1034 are formed as bent edge portions of the disc 1032 and have an inclined surface which faces the disc 1031. If the two discs 1031, 1032 rotated against each other, this inclined surface of the elevations 1034 slides over the edge of the respective opening 1033 or, in the opposite direction of rotation, the elevations 1034 abut the edge of the respective opening 1033 and block rotation of a disc opposite the other. In the second embodiment of the ratchet wheel 103 according to Fig. 2e (right part of the figure), the elevations 1038 are likewise formed by sections 1038 bent out of the plane of the disc 1036, which, however, are closer to the center of the disc 1036 located. The disc 1035 has a plurality of apertures 1037, which are distributed over the circumference of the disc 1035 and in which the elevations 1038, which have an angular difference of 180 ° to each other, can intervene. The elevations 1038 have inclined surfaces, which face the disc 1035, so that a rotation of the two discs 1035, 1036 against each other in one direction of rotation, but blocked in the opposite direction of rotation.

If the lever 2 from its initial position ( Fig. 2c ) in the in Fig. 2a pivoted position shown, the coupling elements 102 are not rotated due to the ratchet wheels 103 and consequently the projections 1021 is not moved. However, when the lever 2 is pivoted back, the ratchet wheels 103 are rotated together with the coupling members 102. In this case, a projection 1021 of each coupling element 102 comes into abutment against a contact surface 104 of the ejector 10, wherein the respective ejector 10 is extended by the forward movement of the projection 1021 which accompanies the rotation of the coupling element 102. The lever 2 is a little over the in Fig. 2b pivoted position shown (to the right), protrudes the projection 1021, which has caused the extension of the ejector 10, into the recess 101 of the ejector 10, wherein the ejector 10 due to the force exerted by the coil spring 11 tensile force returns to its initial position, ie into the respective recording room ( Fig. 2c ). When the lever 2 is pivoted in the direction of the component corresponding to the socket 1 (to the left) ( Fig. 2d ) to the lever 2 in the in Fig. 2a to pivot shown position, the two discs of each ratchet wheel 103 are rotated against each other, so that the pivoting of the lever 2 is not blocked by the projection 1021 protrudes into the recess 101 of the ejector 10.

Fig. 3a to Fig. 3e show a second embodiment of the first embodiment. The separating mechanism is integrated in the socket 1 and comprises two squeezing 20, which are each connected to the socket 1 via a formed as a spiral spring 11 return element with the socket 1. The ejectors 20 have a recess 201 extending in the longitudinal direction thereof. The separation mechanism further includes an associated with each squeezer 20 Coupling element 202 with projections 2021, which are formed as teeth. The projections 2021 are arranged on opposite sides of the coupling elements 202, so that the teeth formed by them on two opposite sides of the coupling elements 202 is interrupted. The projections 2021 are accordingly designed as toothing extending in sections over the circumference of the coupling elements 202. The coupling elements 202 are arranged on the axes 3 and are rotated upon pivoting of the lever 2. For selective rotation of the coupling elements 102, the separating mechanism further comprises ratchet wheels 203, wherein each coupling element 202 is assigned a Sperrklinkenrad 203. Each ratchet wheel 203 consists of two discs, one of which is firmly connected to the respective coupling element 202 and the other with the respective leg 21 of the lever 2.

Fig. 3e shows two possible embodiments of a ratchet wheel, wherein the ratchet wheel in the right field of Fig. 3e from that in the right part of Fig. 2e shown ratchet wheel 103 only differs in that the disc 2036 has only two elevations and the disc 2035 only two openings 2037, which each have an angular difference of 180 ° to each other.

If the lever 2 from its initial position ( Fig. 3c ) in the in Fig. 3a shown pivoted position, the coupling elements 202 are not rotated due to the ratchet wheels 203. However, when the lever 2 is swung back, the ratchet wheels 203 are rotated together with the coupling members 202. In this case, the projections 2021 engage each coupling element 202 in recesses 204 of each squeezer 20, which depressions 204 are formed on a lower boundary surface of the recess 201, wherein by the associated with the rotation of the coupling element 202 forward movement of the projections 2021 of the respective squeezer 20 is extended , The lever 2 is a little over the in Fig. 3b shown pivoted (to the right), protrude the protrusions 2021 in the recess 201 of each ejector 20, wherein the ejector 20 due to the force exerted by the coil spring 11 tensile force returns to its initial position, ie in the respective receiving space ( Fig. 2c ). When the lever 2 is pivoted in the direction of the component corresponding to the socket 1 (to the left) ( Fig. 3d ), the two discs of each pawl wheel 203 rotated against each other, so that the pivoting of the lever 2 is not blocked by the projections 2021 protrude into the recess 201 of the ejector 20.

Fig. 4a to Fig. 4e show a third embodiment of the first embodiment. The separating mechanism is integrated in the socket 1 and comprises two squeezing 30, which are each connected to the socket 1 via a formed as a spiral spring 11 return element with the socket 1. The disengers 30 have a recess 301 extending in their longitudinal direction. The separating mechanism further comprises a coupling element 302 associated with each squeezer 30 and having two peg-shaped projections 3021 which are arranged at an angular difference of 180 ° on the coupling element 302 and, in contrast to the embodiments according to FIGS Fig. 2a to 2e and 3a to 3e , extend in the axial direction (axis of rotation of a coupling element = the direction of the axis 3), ie in the direction of the axes 3. The coupling elements 302 are arranged on the axes 3 and are rotated upon pivoting of the lever 2. For selective rotation of the coupling elements 102, the separating mechanism further comprises ratchet wheels 303, wherein each coupling element 302 is associated with a ratchet wheel 303. Each ratchet wheel 303 consists of two discs, one of which is firmly connected to the respective coupling element 302 and the other with the respective leg 21 of the lever 2.

Fig. 3e shows two possible embodiments of a ratchet wheel 303, which to the in Fig. 3e shown ratchet wheels 203 are identical.

If the lever 2 from its initial position ( Fig. 4c ) in the in Fig. 4a shown pivoted position, the coupling elements 302 are not rotated due to the ratchet wheels 303. However, when the lever 2 is pivoted back, the ratchet wheels 303 are rotated together with the coupling members 302. In this case, a projection 3021 (pin) of each coupling element 302 comes into abutment against a contact surface 304 of the ejector 30, wherein the respective ejector 30 is extended by the forward movement of the projection 3021 which accompanies the rotation of the coupling element 302. The lever 2 is a little over the in Fig. 4b pivoted position shown (to the right), protrudes the projection 3021, which has caused the extension of the squeezer 30, in the recess 301 of the ejector 30, wherein the ejector 30 returns due to the force exerted by the coil spring 11 tensile force in its initial position, ie in the respective receiving space ( Fig. 4c ). When the lever 2 is pivoted in the direction of the component corresponding to the socket 1 (to the left) ( Fig. 4d ), the two discs of each ratchet wheel 303 are rotated against each other, so that the pivoting of the lever 2 is not blocked by the projection 3021 protrudes into the recess 301 of the ejector 30.

Fig. 5a to Fig. 5e show a fourth embodiment of the first embodiment. The separating mechanism is integrated in the socket 1 and comprises two squeezing 40, which are each connected to the socket 1 via a formed as a spiral spring 11 return element with the socket 1. The ejectors 40 have a recess 401 extending in the longitudinal direction thereof. The separating mechanism further comprises a coupling member 402 associated with each squeezer 40, having a projection 4021 in the form of an edge region bent in the axial direction (in the direction of the axis of rotation of the coupling element = in the direction of the axes 3), an incision bounding this edge region extending over part of the circumference of the coupling element 402 extends. In this embodiment of the coupling element 402, the projection 4021 can be elastically deflected in the axial direction against a restoring force exerted by the latter itself due to its material properties. The restoring force at a certain deflection is greater, the longer the edge region. The coupling elements 402 are arranged on the axes 3 and are rotated upon pivoting of the lever 2. Ratchet wheels are not required in this embodiment of the separation mechanism.

Fig. 5e shows the coupling element 402 in two views, in a front view and a perspective view.

If the lever 2 from its initial position ( Fig. 5c ) in the in Fig. 5a pivoted position shown, the coupling elements 402 are rotated, wherein the projection 4021 slides over the edge of the recess 401 of the ejector 40 and thereby deflected in the axial direction, that is pressed into the plane of the coupling element 402. When the lever 2 is pivoted back, the projection 4021 of each coupling element 402 comes to rest against a contact surface 404 the squeezer 40, which is extended by the accompanying with the rotation of the coupling element 402 forward movement of the projection 4021 of the respective squeezer 40. The lever 2 is a little over the in Fig. 5b pivoted position shown (to the right), protrudes the projection 4021 into the recess 401 of the pusher 40 into it, the pusher 40 due to the force exerted by the coil spring 11 tensile force returns to its original position, ie in the respective receiving space ( Fig. 5c ). When the lever 2 is pivoted in the direction of the component corresponding to the socket 1 (to the left) ( Fig. 5d ), the projection 4021 is elastically pressed into the plane of the coupling element and slides over the edge of the recess 401, so that the pivoting of the lever 2 is not blocked by the projection 4021 protruding into the recess 401 of the ejector 30.

Fig. 6 shows a perspective view of a second embodiment of the separation mechanism 50 according to the invention. The separation mechanism 50 includes a carrier 51, on each of which a receiving space 52 is disposed on opposite sides. In the receiving spaces 52 each have a squeezer 53 is arranged with end plates 54. The tabs 54 are intended to engage in the gap between a female connector and a male connector. The separating mechanism 50 further comprises a lever 55, which has two legs 551 and a handle 552 connecting the legs 551. Each leg 551 is mounted on the carrier via an axle 56, the axes 56 each extending into a receiving space 52. The separating mechanism further comprises a fastening device 57, which comprises a steel strip 571 and a clamping element 572. In the clamping element 572, a clamping screw 5721 is arranged, by means of which the steel strip can be tensioned.

This embodiment of a separating mechanism 50 according to the invention can be fixed to a socket or a plug by means of the fastening device 57. Incidentally, the separating mechanism 50 may be configured as well as the above-described embodiments concerning the press-out means, the coupling members, the ratchet wheels and the return member.

Fig. 7 shows a further embodiment of the second embodiment, in which arranged on the legs 551 of the lever 55 each have a lid lifter 5511 is. The lid lifters 5511 face each other and each have an edge inclined with respect to the legs 551, the distance between the edges decreasing in a direction away from the carrier 51. The function of the lid lifter 5511 is in the context of the description of Fig. 8a to 8f clear.

8a to FIG. 8f show a separating mechanism 50 according to the invention in use. The separation mechanism 50 is disposed on a female connector 60 and fixed by means of the fastener 57. A plug 70 is plugged into the socket 60. A lid 61 of the socket 60, which is pressed by a spring down, engages behind with its edge formed on the plug 70 nose 71. The engaging behind the nose 71 by the lid edge prevents accidental disconnection of the connector, since the nose 71 is formed is that the lid edge bi the separation process can not slide over the nose 71. In Fig. 8a is the lever 55 of the separation mechanism 50 in its initial position and is applied to the socket 60 at. For the separation of the socket 60 and plug 70, the lever 55 is pivoted in the direction of the plug 70 until the lever 55 rests on the plug 70, as in Fig. 8b is shown. Subsequently, the lever 55 is pivoted back in the direction of the socket 60 again. In this case, the lid 61 is lifted by the arranged on the legs 551 of the lever 55 lid lifter 5511 on the nose 71, as it is in Fig. 8c is shown. At the same time, the ejectors 53 are extended out of the receiving spaces 52, whereby the plug 70 is pressed out of the socket 60. If the lever 55 is further pivoted in the direction of the socket 60, the lid 61 is released from the lid lifter 5511 and moves due to the restoring force of the spring, via which the lid 61 is connected to the socket 60, down, as in Fig. 8d is shown. Upon further pivoting of the lever 55 in the direction of the socket 60, the squeezer 53 are further extended until they finally reach their maximum position ( Fig. 8e ). If now the lever 55 is slightly further pivoted in the direction of the socket 60, the ejectors 53 automatically return to the receiving spaces 52 by the tensile force exerted by a return element ( Fig. 8f ). The lever 55 is now back in its initial position and the plug 70 can be removed without effort.

Fig. 9 shows a perspective view of a female connector 80 with a third embodiment of the separation mechanism according to the invention. The separating mechanism comprises a sleeve 91, which is arranged on the socket 80 and surrounds it, and two arranged on opposite sides of the socket 80 receiving spaces, in each of which a squeezer 93 with tabs 94 is arranged. The squeezer 93 are extended by rotation of the sleeve 91 on the female connector 80. So that the sleeve 91 provides a better hold for a user, it has circumferentially distributed elevations 911 on its outer surface.

In this embodiment, a thread is disposed on an inner surface of the sleeve 91, in which a portion of each ejector 93 engages. By the threaded engaging portion of the ejector 93, the ejector 93 are extended upon rotation of the sleeve 91 or retracted in opposite rotation.
