From the prior art, a variety of solutions for releasable electrical contact is known, comprising a socket with a female connector housing and a plug with a connector housing or plug a housing-less contact pin or the like.

It is on the pamphlets EP 1 764 874 A2 . DE 102 55 531 B3 . DE 10 2011 082 355 B3 and CN 107 317 167 A directed.

A simple electrical connector is from the publication EP 1 764 874 A2 out. The document discloses an electrical connector for sliding on a contact pin for the purpose of electrical connection, wherein the connector comprises a metal housing having a first wall and one of the spaced second wall extending parallel to the sliding movement relative to the contact pin and the two walls having mutually connecting side walls, wherein on the first wall inside an inwardly projecting fixed contact point is arranged and the second wall adjacent a displaceable parallel to the sliding pressure spring is arranged, which is to be introduced for engagement with the through an insertion opening of the connector contact Pin has certain pressure surface and is pre-bent in the region of the pressure surface in the direction of the first wall in a de-energized state, wherein in a ready for smooth insertion of the contact pin initial state, the pressure spring against the pre-bent n state elastically deformed and held in a detent such that between the stationary contact point and the pressure surface transversely to the direction of displacement, which allows a friction-free insertion of the contact pin to be contacted and the pressure spring seen from the insertion from behind the pressure surface in Having the path of the contact pin projecting projection, wherein the pressure spring is unlatched by hitting the contact pin on the projection of the latch, so that the contact surface comes to rest on the contact pin.

The publication DE 102 55 531 B3 teaches a plug for connection to a socket having a receptacle housing and a receiving space enclosed by a wall and first contacts, wherein on an outer surface of the receiving space enclosing wall at least one latching nose is projecting, comprising a plug housing, which can be inserted into the receiving space has first housing portion having a second housing portion which faces the locking lug when connecting to the female housing. Furthermore, it comprises a slide with a holding stop, which is held on the plug housing along the second longitudinal axis limited adjustable between two positions and acted upon by at least one spring. In the not completely connected state of the plug, the spring holds the slide with its retaining stop biased against a first arm associated with the locking stop. From this, when the fully connected state is reached, the latching lug of the plug-in socket is detachable and, under the action of the spring, can be transferred into a second position representing the fully connected state.

The document describes DE 10 2011 082 355 B3 a socket for a vehicle, wherein the socket has an opening for receiving a plug and a current-contact area for the plug, wherein the socket has a lid, wherein the lid completely covers the contact area in a closed position and in an open position, the contact area for a Contact with the plug releases, wherein the socket further comprises at least two each movable between a starting position and an end position slats, wherein the slats between the defined by the closed position of the lid portion and the upper edge of the opening are arranged, wherein the slats and the lid are coupled together via a locking system, wherein the locking system is adapted to permit movement of the lid from the closed position to the open position only when all the fins have been moved to a predefined position between the home position and the end position.

Finally, the document discloses CN 107 317 167 A [ 4 to 8th ] A method of assembling a connector and the connector itself for a vehicle, the method comprising the steps of: A multiple connector and a multiple socket each have at least one self-locking nose with bevels, which are initially arranged unlocked. The bevels come - when inserting the multiple plug into the multiple socket - in contact, which - by further plugging - the respective outer frame of the multiple plug and the multiple socket elastically deform, after which the vertexes of the noses overlap. The elastic deformation of the outer frame reaches a maximum. At this moment, the multiple contact pairs of the multiple plug and the multiple socket come into contact with each other. If the insertion continues even further, the multiple plug is mounted in the multiple socket after deformation recovery of the respective outer frame, since the vertexes of the noses are exceeded and the contact pairs are contacted and the multiple plug is releasably locked in the multiple socket.

A disadvantage which relates to all known solutions consists in the wear of the contact pairs in the contacting in the contact areas by plugging and unplugging the plug. It comes in the contact area to undesirable fretting corrosion. In most cases, there are high insertion forces during insertion and high pulling forces when pulling, because the contact forces in the contact area are high. In addition, there are the forces that must be overcome by the locking and unlocking of the plug-socket connection when plugging and unplugging the plug.

The 1 to 4 show a plug using common reference numerals 10 with a connector housing, not shown, the at least one male contact element 10.1 having.

The 1 to 4 continue to show a socket 20 with a socket housing 20.1 , which is designed as a contact housing and thus at least one female contact element 20:11 having.

The female contact element 20:11 is part of a car contact locking mechanism K that have at least one mechanical suspension K.1 and at least one mechanical shift bracket K.2 in the socket housing 20.1 is arranged and held.

In the exemplary embodiment, the auto-contact locking mechanism K axially symmetric to a longitudinal axis X , The plug-in socket unit plugged in the assembled state 10 . 20 two suspensions K.1 and several sliding supports K.2 in the socket housing 20.1 on.

Is the plug located? 10 outside the socket 20 , It is in a non-assembly state in a state not shown Z0 ,

To the car contact locking mechanism K heard a pressure point element K.3 , on which in the direction of the longitudinal axis X pressure can be exerted in the + x direction, which causes the auto-contact locking mechanism K from a locked contactless state Z1 in a locked and contacting state Z2 . Z3 comes as explained below.

In 1 is the first - locked and contactless - condition Z1 the car contact locking mechanism K shown.

This first state Z1 is reached when the plug 10 with its male contact element 10.1 in the socket housing 20.1 is plugged and finally plugged. The plugging direction runs along the longitudinal axis X in the + x direction.

In this first state Z1 is the connector housing not shown in the socket housing 20.1 coupled by means of a mechanical coupling locking mechanism, not shown, in particular latched, which is not the subject of this invention. Various mechanical solutions are known from the prior art and can be used accordingly.

By comparing the 1 and 2 it becomes clear that the plug contact element 10.1 of the plug housing in the first state Z1 after a first pushing push (push 1 ) in the direction of the longitudinal axis X in the socket housing 20.1 the pressure point element K.3 not yet touched, that is to say at a predeterminable distance Ax to the pressure point element K.3 is arranged.

In the first state according to 1 is the auto-contact locking mechanism K thus not yet actuated and the auto-contact locking mechanism K is locked in an "open state" and with respect to the male contact element 10.1 contactless, so that the female contact elements 20:11 not yet with the male contact element 10.1 to contact.

Condition 2:

In 2 is a second state Z2 the car contact locking mechanism K shown.

This second locked contacting state Z1 is reached when the plug 10 with its male contact element 10.1 further than in 1 in the socket housing 20.1 put into it. The plugging direction continues along the longitudinal axis X in the + x direction. In this second state Z2 the plug housing remains in the socket housing 20.1 coupled by means of the mechanical coupling locking mechanism, not shown, in particular latched.

Out 2 it becomes clear that the plug contact element 10.1 of the plug housing in the state 2 after a second step, a second pushing push (push 2 ) in the direction of the longitudinal axis X in + x-direction in the socket housing 20.1 retracts and the pressure point element K.3 touched, that is the distance Ax bridged and on the pressure point element K.3 acting depressing, so that the pressure point element K.3 in + x-direction by distance Ax is moved mechanically.

In this second state Z2 is due to the mechanical contacting of the pressure point element K.3 the car contact locking mechanism K operated and according to 2 is the auto-contact locking mechanism K now the male contact element 10.1 contacting locked in a "closed" state, so that the female contact elements 20:11 with the male contact element 10.1 contact, like 2 shows.

In other words, by overpowering (Push 2 ) of the plug 10 is the schematic representation of the front side of the male contact element 10.1 to the pressure point element K.3 the car contact locking mechanism K pressed, creating a closed contact between the contact surfaces of the male contact element 10.1 the plug housing and the female contact element 20:11 of the female connector housing 20.1 is effected.

It is preferably provided that the outside of the socket housing 20.1 a small viewing or inspection opening is arranged so that it can be checked whether the contact was made mechanically.

The auto-contact locking mechanism K is designed such that by the force acting on the pressure point element K.3 is exercised, a trigger mechanism of a charged energy storage is activated, which emits its stored power by the trigger, so that the auto-contact locking mechanism K mechanically over the two suspensions K.1 and the multiple sliding supports K.2 a shift of the elements of the auto-contact locking mechanism K causes, as will be explained further.

It becomes clear that the coupling of plug 10 and socket 20 in the first step, without the male contact element 10.1 the plug housing with the female contact elements 20:11 of the female connector housing 20.1 electrically contacted, thereby advantageously a contact-side frictional engagement between the male contact element 10.1 the plug housing and female contact elements 20:11 of the female connector housing 20.1 as a result of plugging and pulling the plug 10 is avoided.

By the release mechanism of the charged energy storage, the energy storage was activated, which gives off its power such that auto-contact locking mechanism K in the in 2 shown position in the state Z2 remains, even if the second pushing push (push 2) in the direction of the longitudinal axis X is ended. After completion of override (push 2) the state 3 reached.

Condition 3:

In 3 is the third state Z3 the car contact locking mechanism K shown.

The overpressure (push 2) of the plug 10 will be terminated. That is, the second step is ended or a third step follows, which consists in the completion of the second step.

The male contact element 10.1 of the plug housing reverses on the longitudinal axis X in the opposite direction in the situation according to state Z1 back. The contact of the male contact element 10.1 the plug housing with the female contact elements 20:11 of Female connector housing 20.1 remains however (unlike in 1 shown) according to 3 closed.

Condition 4:

In 4 is the fourth state Z4 the car contact locking mechanism K shown.

To the car contact locking mechanism K heard the pressure point element K.3 on which to cancel the contacting lock the auto-contact locking mechanism K according to 3 in a fourth step in the direction of the longitudinal axis X a compressive force on the pressure point element K.3 is applied, which is carried out in the opposite direction in the -x direction, whereby the auto-contact locking mechanism K from the locked contacting state Z3 in the locked "open" contactless state Z4 comes, the first state Z1 equivalent.

The lock is by a means K.4 solved that to the auto-contact locking mechanism K belongs or is designed as a separate tool, as in 4 is indicated schematically.

By operation by means K.4 comes the auto-contact locking mechanism K from the locked "closed" state Z3 in the locked "open" state Z4 that the state Z1 equivalent.

The plug 10 can starting from 4 from the socket 20 be pulled without a contact-side frictional engagement between male contact element 10.1 the plug housing and female contact elements 20:11 of the female connector housing 20.1 exists, since in this step, only the mechanical coupling locking mechanism, not shown, is opened in an advantageous manner.

When opening the mechanical coupling locking mechanism can in one embodiment, the means K.4 be used effectively, since the decoupling of the mechanical coupling locking mechanism with the operating direction of the auto-contact locking mechanism K to change from the closed state Z3 in the "open" state Z4 matches.

Advantageously, thus the forces of the mechanical coupling locking mechanism between plug 10 and socket 20 be designed independently of the forces that occur when contacting the closed contact (state 2 ; 2 and condition 3 ; 3 ) between the contact surfaces of the male contact element 10.1 the plug housing and the female contact element 20:11 of the female connector housing 20.1 needed.

The 5 shows a schematic representation of an embodiment of the auto-contact locking mechanism K with the contact surface 11 of the socket contact element 20:11 that with a contact surface 1 of the plug contact element 10.1 contacted, in a sectional view along the insertion direction x of the plug 10 to explain the principle of the energy storage in a possible embodiment.

Constructive in this embodiment is the female contact element 20:11 as a contact spring F executed in the manner of a buckling bar, by an over-spring BB compressed and depending on the desired condition F-Z1 or F-Z2 . FZ3 kinks in different directions, as explained below.

5 shows the male contact element 10.1 and the contact spring F in different spring element states F-Z1 . F-Z0 and F-Z2 ( F-Z3 analogous).

In the spring element state F-Z0 is the contact spring F not compressed.

In the spring element state F-Z1 is the contact spring F with respect to the contact surface 1 of the plug contact element 10.1 convex - outward from the male contact element 10.1 away - compressed and thus does not contact with the contact surface 1 of the plug contact element 10.1 ,

Because of the contact spring F in the spring element state F-Z1 with respect to the contact surface 1 of the male contact element 10.1 convex - outward from the male contact element 10.1 away - is compressed, it ensures that the car contact locking mechanism K in the states Z1 and Z4 having a Kontaktöffnungsmaß that a non-contact insertion and removal of the plug 10 in the socket 20 allows, as the auto-contact locking mechanism K with their female contact elements 20:11 not at the contact surface 1 of the plug contact element 10.1 contacted.

In this spring element state F-Z1 represents the contact spring F a charged energy storage, which is either always charged or by a push-in movement of the plug 10 in the socket 20 is loaded, as will be explained.

This charged energy storage, the contact spring in the state F-Z1 , however, is activated only by the already mentioned release mechanism of the charged energy storage.

In the activated spring element state F-Z2 is the contact spring F with respect to the contact surface 1 of the male contact element 10.1 concave - inward to the male contact element 10.1 down - compressed and thus contacted with the contact surface of the male contact element 10.1 ,

In this spring element state F-Z2 represents the contact spring F an activated at least partially discharged energy storage, which is activated by the trigger mechanism, as will be explained further.

The charged energy storage F-Z1 namely, is activated only by the already mentioned release mechanism of the charged force accumulator.

The 6 shows the auto-contact locking mechanism K in a schematic representation with the contact surface 11 of the socket contact element 20:11 who is not yet (cf. 8th ) with the contact surface 1 of the plug contact element 10.1 contacted.

The spring element F is in the spring element state F-Z1 in which the spring element F charged as energy storage and not yet activated.

The "charging", hence the upsetting of the spring element F , Is carried out by a loading element, which in the embodiment an over-spring element BB is which is the spring element F either always in the charged state F-Z1 holds or from the spring element state F-Z0 in the charged state F-Z1 brings as soon as the plug 10 in the socket 20 is inserted.

In other words, the over-spring element acts BB with a force F1 (see. 6 ) at the latest on the spring element F and generates the spring element state F-Z1 if the plug 10 in the socket 20 is inserted and in the state Z1 (see. 1 ) is located.

In the first step thus takes place in an advantageous manner in addition to the insertion of the plug 10 at the same time the charging of the spring element F in the spring element state F-Z1 by moving the over-spring element BB in + x-direction, which according to 6 the over-spring element state BB-Z1 occupies.

The displacement of the over-spring element BB in the + x-direction is carried out by appropriate coupling of the release mechanism otherwise not shown with the auto-contact locking mechanism K ,

For example, an element of the plug 10 on the socket side arranged over spring element BB and thus act on the socket side also arranged spring element when the plug 10 in the first step in the socket 20 is inserted.

The spring element BB and the spring element F provide in this embodiment, a spring element unit F . BB represents.

The 7 shows the tripping mechanism of the auto-contact locking mechanism K in a schematic representation in a plane transverse to the in 6 shown level with the contact surface 11 of the socket contact element 20:11 that with the contact surface 1 of the plug contact element 10.1 for making the contact between plugs 10 and socket 20 contacted, whereby the condition Z1 in 1 which is in the state in 2 replaced.

According to the invention is provided, during or at the end of the second step (transition from the state Z1 in the state Z2 ) by triggering the auto-contact locking mechanism K (= Release operation), the stored force of the spring element F-Z1 on the contact surface 1 of the meantime in the state Z1 brought connector contact element 10.1 of the plug 10 to let act.

The triggering is preferably carried out when overpressing (push 2) of the plug 10 according to the schematic representation in 2 where not the end face of the male contact element 10.1 to the pressure point element K.3 the car contact locking mechanism K presses, but according to the embodiment, a cam N with a force off the longitudinal axis X radial direction (cf. 8th ) on the top of the spring element F in the spring element state F-Z1 acts.

This will be the closed contact 1 . 11 between the contact surfaces 1 and 11 of the plug contact element 10.1 the plug housing and the female contact element 20:11 of the female connector housing 20.1 causes, as in 8th is shown.

The 8th shows the auto-contact locking mechanism K with the contact surface 11 of the socket contact element 20:11 that with the contact surface 1 of the plug contact element 10.1 contacted, with this contacting in the states Z2 and Z3 according to the 2 and 3 is present.

Out 7 becomes clear that the triggering when pushing (push 2) of the plug 10 according to the schematic representation in 2 through the cam N takes place, for example, on the underside of the over-spring element BB is arranged.

As already explained, it is inventively provided that the contact spring F in the spring element state F-Z1 with respect to the contact surface 1 of the plug contact element 10.1 convex - outward from the male contact element 10.1 gone - compressed.

This upsetting is done by means of the over-spring element BB in the axial direction + x-direction in the first step according to FIG 1 while the over-spring element BB in the second step of over-pressing (push 2) now in a rotational movement according to the arrow P in 7 around the longitudinal axis X rotated so that the triggering at the pressure point element K.3 by means of the cam N takes place on the top of the spring element F in the spring element state F-Z1 acts and the spring element state F-Z2 of the spring element F causes.

The spring-loaded cam N thus becomes transverse to the contact spring F rotating on a circular path around the longitudinal axis X shifted, so that the contact spring the state F-Z1 leaves and the state F-Z2 accepts.

By the on the underside of the over-spring element BB arranged cams N changes the designed as a buckling contact spring F with respect to the contact surface 1 of the plug contact element 10.1 abruptly from convex to concave - inward to the male contact element 10.1 contacted and contacted (cf. 8th ) with their contact surface 11 with the contact surface 1 of the plug contact element 10.1 ,

In other words, the plug 10 will be in the socket 20:11 introduced, that is plugged and over the described means, in particular the spring element combination F . BB from contact spring F and spring element BB an external force acts, in particular the cam N (with the force F2 ) on the contact spring F , with which a reversal of the buckling direction of convex F-Z1 too concave F-F2 is reached.

It is understood that the triggering force F2 is greater than the counteracting force of the spring element F in its convex spring element state F-Z1 , so that the triggering force F2 the spring element F as a bent rod of convex spring element state F-Z1 in the concave spring element state F-Z2 . F-Z3 brings.

This is achieved by appropriate design and positioning of contact spring F and spring element BB or the geometric configuration of the cam N guaranteed.

The advantages consist summarized in that in the first step, a non-contact (auto-contact locking mechanism K open = contactless) Plug-in operation of the plug 10 in the socket 20 is possible.

Further, the fretting of the contact surfaces of the contact surfaces 1 . 11 of plug contact element 10.1 and socket contact element 20:11 minimized because the contacting of the contact surfaces 1 . 11 when plugging and unplugging the plug 10 is canceled.

Because the release mechanism of the auto-contact locking mechanism K in the second step, only after the production of the connector in the first step, a release of the auto-contact locking mechanism K causes, is advantageously ensured that the contact only when properly, that is completely, manufactured plug-socket connection 10 . 20 he follows.
