Description

Plug-in connecting device with shielding support

Technical Field

The invention relates to an electrical plug-in connection with a plug-in connector and a mating plug-in connector according to the preamble of claim 1.

Background

In order to increase the electromagnetic compatibility of the electrical plug-type connection, the connected cable, the circuit board, the plug-type connector and/or the mating plug-type connector are generally provided with a ground shield which at least prevents or prevents as far as possible the penetration and/or radiation of electromagnetic fields. By the following means: the shielding on the plug-in connector side is conductively connected to the shielding on the mating plug-in connector side corresponding thereto, so that continuous shielding is achieved. In patent document EP 2107648B 1, this is achieved by: the shielding mount of the plug connector comprises spring contacts which project from the main plane of extension and are provided for electrically contacting (or contacting) sections of the electrically conductive wall which are electrically conductively connected to the housing of a mating plug connector of a corresponding design of the plug connector.

Disclosure of Invention

The object of the invention is to provide an alternative embodiment of such an electrical plug-in connection.

This object is achieved by an electrical plug-in connection having the features of independent claim 1. Advantageous embodiments can be found in the dependent claims.

To this end, an electrical plug-type connection is provided, which comprises a plug-type connector and a mating plug-type connector, which is designed to correspond to the plug-type connector.

The plug-type connector comprises one or more plugs and/or one or more sockets, wherein the mating plug-type connector comprises one or more mating sockets configured corresponding to the plugs and/or one or more mating plugs configured corresponding to the sockets. The plug connector and the mating plug connector thus have plug surfaces which correspond to one another. In this way, the plug connector and the mating plug connector can be plugged into one another. The plug-type connection device can thus be transferred from an unmated state (in which the plug-type connector and the mating plug-type connector are not inserted into one another) into a mated state in which the plug-type connector is inserted into the mating plug-type connector by being moved in the insertion direction.

The mating plug connector has a mating plug housing. Furthermore, an electrically conductive wall is provided on the mating plug connector, in which wall a wall cutout is provided. In principle, the shape of the wall cutouts can be set arbitrarily. The wall cutouts are preferably rectangular or circular in configuration. Particularly preferably, the wall cutout is configured to correspond to the contour of a mating plug housing of a mating plug connector. The wall furthermore preferably extends in a plane transverse to the insertion direction. In this case, the wall cutout is preferably defined by an edge which may extend in the insertion direction or have a rise

So that the edge extends at an angle thereto. In contrast to EP 2107648B 1, this embodiment does not require a section bent out of the wall.

The mating plug housing is provided for receiving a plug and/or a socket of a mating plug connector. The plug-in surface of the mating plug-in connector, which is defined by the plug and/or the socket of the mating plug-in connector, can thus be accessed from the outside through the wall cutout.

In the assembled state, the plug connector is inserted into the mating plug connector through the wall cutout. One or more plugs of the plug connector are then electrically conductively connected to the corresponding socket or sockets of the mating plug connector, and/or one or more sockets of the plug connector are electrically conductively connected to the corresponding plug or plugs of the mating plug connector.

The plug-in connector has a base plate on which a plug-in housing is arranged, which plug-in housing is preferably screwed, riveted, soldered or otherwise mechanically connected to the base plate, the base plate serves as a shielding element for the plug-in connector, in a preferred embodiment the base plate is designed to be electrically conductive for this purpose, the base plate can then be produced inexpensively from a flat strip material, for example from a metal plate, it is also preferred that the base plate is produced from an electrically non-conductive matrix, for example from plastic, wherein the matrix has an electrically conductive coating, for example a copper coating, the base plate can furthermore be designed as a circuit board, in an embodiment as a circuit board the base plate has at least one or more electrically conductive layers (coatings), wherein preferably at least one of these layers or at least one conductor plane or at least one layer of strip conductors (L eiterbahn) serves as a shielding element.

The plug housing receives a plug and/or a socket of the plug connector. In a manner similar to the mating plug connector, the plug and/or the socket of the plug connector define a plug surface of the plug connector. Preferably, signal cables and/or power cables and/or data cables or other hybrid cable embodiments are connected to the plug and/or socket of the plug connector. In addition, other electrical components may be provided on the substrate. Signal and/or power and/or data lines or hybrid cable embodiments have shields conductively connected to the substrate.

The plug-in connection also has a contact element which is provided for electrically connecting a shield of the plug-in connector with a shield of a mating plug-in connector. Preferably, the contact element enables an automatic connection, i.e. an electrical connection, of the shield of the plug connector to the shield of the mating plug connector during the plugging process, i.e. when the plug connector is transferred from the unmated state to the mated state. Therefore, no tools are required and the plugging process can be performed simply and quickly even by a layperson.

Furthermore, the plug housing has an actuating element which extends in a housing section of the plug connection. The actuating element preferably serves as an auxiliary element, preferably for disconnecting the plug connector from the mating plug connector in the fitted state of the plug connector device. In a further preferred embodiment, the actuating element is provided for connecting the plug connector to a mating plug connector, in particular for latching.

The plug-in connection is characterized in that the contact piece is arranged in the housing section. The housing section is a space of the plug-in connection, in which a control element of the plug-in part is arranged in the assembled state of the plug-in connection and which extends over the entire width of the control element. The installation space required for the actuating element is therefore always available here for the contact elements. The dimensions of the plug-in connection are therefore not changed by the contacts.

By means of this arrangement of the contact pieces, an electrical connection of the shield of the plug connector to the shield of the mating plug connector in the housing section can be achieved.

In order to ensure a permanent electrical connection between the plug and/or socket of the plug connector and the plug and/or socket of the mating plug connector and between the plug connector and the shield of the mating plug connector in the assembled state, even under vibrational loading, the plug connector and the mating plug connector are preferably connected to one another in a force-fitting and/or form-fitting manner in the assembled state. The plug connector and the mating plug connector are preferably releasably connected to one another, in particular latched to one another.

In order to releasably connect the plug connector to the mating plug connector, the plug connector preferably has a latching means which, in the assembled state of the plug connector, latches with a mating latching means of the mating plug connector. The locking element is then in the locked state. Furthermore, the latch can be disengaged, preferably by actuating the actuating element. When the actuating element is actuated, the latching means is then unlatched from the latching counterpart of the mating plug connector, so that the latching means is then in an unlatched state, in which the plug connector is no longer connected with the mating plug connector in a non-positive and/or positive manner, and the plug connector device can be transferred from the fitted state into the unassembled state by moving the plug connector counter to the insertion direction.

In principle, embodiments are also possible and preferred in which the plug connector is latched to the mating plug connector by actuating the actuating element and is thus transferred from the unlocked state into the latched state. However, the following description relates to embodiments in which the actuating element is used to disengage the plug-in connection.

For this purpose, the actuating element is preferably designed as a push button and is arranged so as to be rotatable about an axis. The actuating element preferably has an actuating surface for this purpose. When the actuating surface is pressed, the actuating element is reversibly rotatable about the axis in the direction of rotation, wherein the locking element is reversibly transferred from the locked state into the unlocked state.

In a first preferred embodiment, the actuating element simultaneously also serves as a catch. Thus, no other member is required as a latch. This embodiment is therefore advantageous with regard to the component expenditure and the production costs. The actuating element of this embodiment preferably has a latching element. The detent element is preferably a detent lug or detent recess (rastaunehmung). In the assembled state, the latching element preferably interacts with a latching counterpart element of the mating plug connector in a latching manner.

The contact piece of this embodiment can be designed elastically, in particular resiliently. However, it is preferred that the contact is designed as an inelastic molded part, for example as a lug, screw or plug.

Embodiments are also preferred in which the contact element simultaneously serves as a latching element and/or is fastened to the actuating element. These embodiments are also advantageous with regard to the component expenditure and the production costs. Furthermore, these embodiments also enable a very quick and simple assembly of the plug-in connection.

In these embodiments, the contact piece is preferably designed as a stamped and bent part. Furthermore, the contact piece is also preferably made of spring steel, so that it is resiliently embodied and can be adjusted against a restoring force. Furthermore, the contact piece is preferably screwed to the base plate, for example, between the base plate and the plug housing. In this case, the contact piece is shaped according to the invention in such a way that it extends in a housing section of the plug-in connection.

In a first preferred embodiment, in which the contact simultaneously also serves as a latching means, no further components are required as latching means. In this embodiment, the contact piece preferably has a latching element. The latching element can also be designed as a latching nose or as a latching recess. In the assembled state, the latching element preferably interacts with a latching counter-element of the counter-plug connector in a latching manner. In this case, the latching counter-element is preferably electrically conductive.

In a second preferred embodiment, in which the contact piece is fixed to the actuating element, the contact piece is adjusted simultaneously with the actuating element when the actuating element is actuated. In this embodiment, the shield of the plug connector and the shield of the mating plug connector are disconnected by means of an electrical connection produced by the contact piece when the actuating element is actuated. The contact piece can be screwed or riveted to the actuating element. Furthermore, the contact piece can be fixed to the actuating element in a form-fitting manner (for example by insertion into a groove or recess of the actuating element) or else in a material-fitting manner (for example by gluing).

In a third embodiment, it is very particularly preferred if the contact piece simultaneously also serves as a latching means and is additionally fastened to the actuating element. The contact element of this embodiment is reversibly switchable from the latched state into the unlatched state when the actuating surface of the actuating element is actuated. In addition, the shields of the plug connector and of the mating plug connector, which are electrically conductively connected to one another via the contact pieces, are disconnected from one another. In this way, not only is an additional latching element omitted, but the contact of the shielding elements of the external plug connector and the mating plug connector with the actuating element can be actively released by the operator. Furthermore, the contact piece of this embodiment is simultaneously used for resetting the actuating element. The adjustment from the latched state into the unlatched state is then carried out against the restoring force of the contact piece. In this case, the actuating element is rotated against the direction of rotation by the restoring force of the contact element when the actuating surface is open. Therefore, an additional reset member is not required to reset the operating member.

The mating plug connector preferably comprises a backplane. The base plate is preferably designed as a circuit board and has at least one electrically conductive layer arranged on an electrically non-conductive substrate. The printed circuit board may also have a plurality of layers, which are each insulated from one another by a non-conductive matrix. Other electrical components may be provided on the circuit board. These electrical components can be electrically connected to each other and/or to a mating plug connector according to the specifications of the circuit diagram.

The base plate, in particular at least one layer or a part of a layer of the base plate and/or the wall, preferably serves as a shielding element for the mating plug connector. The wall serving as a shield acts as a touch protection for the operator.

In a preferred embodiment, the mating plug connector has a contact counterpart for electrically conductively connecting the contact element to the base plate and/or the wall. The contact partners are preferably produced as stamped and bent parts from a flat strip. The contact partners are preferably made of an electrically conductive material, for example copper or a copper alloy. The contact partners can also be made of spring steel. The base plate and/or the wall are preferably connected in an electrically conductive manner to a contact partner of a mating plug connector. For this purpose, the contact partner can, for example, preferably be soldered or screwed to the base plate, so that the contact partner is electrically conductively connected to the layer or layer section serving as the shield. Additionally or alternatively, the contact partner can be connected to the wall in an electrically conductive manner by means of a cable. For this purpose, the contact partner preferably has at least one fixing pin or fixing tab which can be inserted into a through-hole of the base plate and/or is designed to fix a cable lug.

The mating plug housing of the mating plug connector is preferably fixed on the housing side of the base plate in the interior of the mating plug connector. Preferably, the mating plug-in housing is screwed, riveted and/or soldered to the base plate. In a preferred embodiment, the mating plug housing has at least one plug strip which comprises a plurality of soldering pins arranged in a row. These solder pins are provided for electrically connecting the plug and/or the socket of a mating plug connector to the strip conductors of the backplane. Preferably, the mating plug housing of this embodiment is fixed to the base plate by soldering the soldering pins to the base plate. Alternatively or additionally, the mating plug housing may be screwed or riveted to the base plate.

The contact partner is preferably arranged at least partially in the mating plug housing. The mating plug housing particularly preferably has a contact space. In a preferred embodiment, the contact space is arranged between the wall and a plug strip of the mating plug connector. Furthermore, the contact space is arranged in alignment with the housing section. The contact piece is preferably connected in an electrically conductive manner to the contact counterpart in the contact space in the assembled state.

For this purpose, the contact partners have contact and/or latching tabs. The contact and/or latching tabs are preferably positioned in the contact space.

In the embodiment in which the actuating element serves as a catch, it is preferred that the contact and/or catch webs have contact elements. The contact element is used for making electrical contact with the contact. The contact element may be configured as a notch or as a contact nose. Here, the notch embodiment is preferable. In this embodiment, the contact piece, which is designed as a plug or a screw, can be guided through the recess, so that the contact piece is in electrical contact with the recess. The shielding of the plug connector and the shielding of the mating plug connector are thereby connected to one another in an electrically conductive manner.

If the contact piece simultaneously also serves as a latching means, the contact and/or latching tab preferably has a latching counterpart element which is formed correspondingly to the latching element of the contact piece. The latching element and the latching counter-element are provided not only for the electrical contact of the contact piece with the contact counter-piece, so that the shield of the plug connector and the shield of the counter-plug connector are connected to each other in the fitted state in an electrically conductive manner. The latching element and the latching counter-element are also provided for latching together. For this purpose, the latching element and the latching counter-element preferably engage one another in the assembled state and are in electrically conductive contact (or contact). In this case, it is preferred that either the latching element is embodied as a recess and the latching counter-element is embodied as a latching nose or a latching tab, or vice versa. This embodiment of the plug-in connection can be assembled and disassembled very quickly and easily.

In an embodiment in which the contact piece is alternatively or additionally fixed to the actuating element, it is furthermore preferred that the latching element and/or the latching counter-element are designed to be sprung in order to ensure a reliable contact of the contact piece with the contact counter-element. In this embodiment, it is preferred that either the latching element is designed as a recess and the latching counter-element is designed as a latching nose or a latching tab, or vice versa.

According to the preamble of claim 1, the plug-in connection is provided according to the preamble of the accompanying claim 14, characterized in that the contact element is designed as a spring and is pushed onto the edge of the wall in such a way that the contact element makes contact with the wall in an electrically conductive manner.

In this embodiment of the plug-in connection, the plug-in connector is latched to the mating plug-in connector by means of the actuating element.

In the assembled state of the plug-in connection, the spring is preferably positioned between the base plate and the wall and connects the base plate and the wall to one another in an electrically conductive manner. The spring serves here at the same time as a tolerance compensation element. The spring is made of an electrically conductive material, preferably copper or a copper alloy or spring steel.

When the plug connector is inserted into the mating plug connector, the spring is displaced against its restoring force, so that the spring is pressed with the restoring force from the edge of the wall onto the substrate. Thereby, an electrical contact between the substrate and the wall can be ensured even in case of a vibration load.

An advantageous variant of this solution is characterized in that the contact spring has two legs lying opposite one another, which are provided for fixing the contact spring to the wall, wherein the wall is pushed between the legs such that the legs are pressed apart against the restoring force of the spring, so that the spring is clamped against the wall.

It can also be provided with advantage that the legs are connected to one another by an arcuate first spring portion, wherein the first spring portion is provided for contacting the circuit board and the spring has a second spring portion which extends out of one of the legs toward the open end.

According to a further development which can be produced in a simple manner and is assembled in a good manner, it can furthermore be provided that the first spring part and the second spring part are arranged on the spring legs alternately in the direction of extension of the spring, and that the second spring part is formed more flat than the first spring part, so that the wall strikes the second spring part when inserted between the spring legs, wherein the first spring part is raised relative to the second spring part.

The plug-in connection according to the invention can be assembled quickly and easily. In an embodiment in which the contact element simultaneously also serves as a latching means and/or is arranged on the actuating element, the plug connector and the mating plug connector can be assembled without tools and can also be assembled very quickly by a layman. The spring which can be plugged onto the edge can furthermore be fitted very easily.

Detailed Description

Fig. 1 shows a plug-in connection 100 according to the invention. The plug-in connection device 100 has a plug-in connector 1 and a mating plug-in connector 2. Fig. 1(a) shows the plug connection device 100 in the unassembled state U, fig. 1(b) shows the plug connection device when the plug connector 1 is inserted into the mating plug connector 2, and fig. 1(c) shows the plug connection device 100 in the assembled state M, in each case in a sectional view. Fig. 1(e) shows a perspective view of the plug connector 1 of the plug connection device 100 in a sectional view, and fig. 1(f) shows the plug connection device 100 in the assembled state M in a perspective view. Fig. 1(d) also shows the contact counterpart 4 of the mating plug connector 2 of the plug connector device 100 in a perspective view.

The plug connector 1 has a base plate 13 which serves as a shielding element for the plug connector 1. The substrate 13 is made of a metal sheet 13 and is electrically conductive. Furthermore, the plug connector 1 has a plug housing 10 arranged on a substrate 13. In the embodiment shown, the plug housing 10 is screwed to the base plate 13 by means of screws 15. However, the plug housing 10 can also be fastened, glued or otherwise fixed to the base plate 13.

In order to simplify the positioning of the plug connectors 1 when inserting the plug connectors 1 into one another into the mating plug connector 2, the base plate 13 has positioning tabs 131 which are designed in the manner of a tongue and extend in the insertion direction 30 transversely to the extension direction 31.

The plug housing 10 comprises a first housing part 11, in which a plurality of signal and/or data line sockets 111 for the electrical connection of signal lines (not shown) are provided, and a second housing part 12, in which a power line socket 121 for the electrical connection of a power line (not shown), in particular a power cable, is provided. The signal and/or data line sockets 111 and the power line sockets 121 are arranged side by side in rows in the direction of extension 31. In the second housing part 12, between the power supply line sockets 121, a handling element 16 is also provided, which has a width B in the direction of extension 31 (see fig. 1(f)) which defines a housing section 160. In the assembled state M (see fig. 1(c)), the housing section 160 is a structural space of the plug-in connection 100, in which the actuating element 16 is positioned and which has the width B of the actuating element 16.

Between the plug connector 1 and the substrate 13, contacts 14 are arranged in the housing section 160. The contact 14 is bent in a stepped manner and has a fixing leg 145 (see fig. 1(b)), a contact leg 147 and a connection tab 146, wherein the connection tab 146 connects the fixing leg 145 with the contact leg 147. The fastening leg 145 has an open fastening end 1441, near which a through-opening 1450 is provided, which is provided for fastening the contact piece 14 in the plug connector 1. The contact 14 is fixed to the substrate 13 by means of a screw 15, which is guided through the through-opening 1450 and screwed into the plug housing 10 of the plug connector 1, so that it contacts the substrate in an electrically conductive manner. The contact 14 can also be configured in an unbent, S-shaped, Z-shaped, ramp-shaped or similarly curved manner.

The contact 14 of this embodiment is provided for electrically connecting the shield of the plug connector 1 to the shield of the mating plug connector 2. In the embodiment shown here, the contact piece is also provided for latching the plug connector 1 with the mating plug connector 2 in the assembled state M of the plug connector device 100. The contact piece 14 of fig. 1 thus simultaneously forms a latching means. For this purpose, the contact piece has an open latching end 1442 on its contact leg 147, on which latching element 1470 is arranged. The detent element 1470 is embodied here as a recess.

In addition, the contact piece 14 is fixed to the actuating element 16 by means of a rivet 18 (see fig. 1(e)) which passes through the contact leg 147.

The actuating element 16 is provided in the assembled state M of the plug-in connection device 100 for disconnecting the plug-in connector 1 from the mating plug-in connector 2. For this purpose, the actuating element is configured as a push button which is rotatable about an axis (not shown) in the direction of rotation 61 and has an actuating surface 161. Thereby, when the manipulation surface 161 is pressed in the rotation direction 61, the manipulation piece 16 rotates about the axis. Since the contact leg 17 is fixed to the actuating element 16, the contact piece 14 is adjusted simultaneously with the actuating element 16 when the actuating element 16 is actuated. In the exemplary embodiment shown, the contact leg 147 is bent when the actuating element 16 is rotated in the direction of rotation 61. For this purpose, the contact piece 14 is of resilient design and is made of spring steel.

The mating plug connector 2 has one or more mating plug housings 21, in which plugs (not shown) are arranged, which are designed to correspond to the

receptacles

111, 121 of the plug connector 1. The mating plug housing 21 of the mating plug connector 2 is arranged in the interior 202 on a housing side 242 of the base plate 24, which may be designed as a circuit board. The housing 21 and the base plate 24 are fixed to a wall 22 which extends in a plane (not shown) formed by an extension direction 31 and a transverse direction 32 extending transversely to the extension direction 30. Wall cutouts 23 are provided in the wall 22, through which wall cutouts a mating plug connector 2 is accessible from the outside 201. The plug connector 1 can be inserted into the mating plug connector 2 through the wall cutout 23 in an insertion direction 30 transverse to the wall 22. When the plug connector 1 is inserted into the mating plug connector 2, the plug connector device 100 is transferred from the unassembled state U to the assembled state M.

In the embodiment of fig. 1, the base plate 13 of the plug connector 2 serves as a shield. In order to connect the shielding element, i.e. the base 13, of the plug connector 1 in an electrically conductive manner to the shielding element, i.e. the base plate 24, of the mating plug connector 2, the mating plug connector 2 has a contact partner 4, which is electrically conductively connected to the contact elements 14 of the plug connector 1 when the plug connector 1 is inserted into the mating plug connector 2.

The contact counterpart 4 has a contact and/or latching web 41, on which a latching counterpart element 410 is arranged. The latching counter-element 410 is designed as a latching nose and interacts with a latching element 1470 of the contact piece 14, which is designed as a recess, when the plug connector 1 is inserted into the counter-plug connector 2. Here, the detent lugs 410 are at least partially ramp-shaped. Thus, when the plug connector 1 is inserted into the mating plug connector 2 along the ramp (not shown) of the latching nose 410, the open latching ends 1442 of the contact legs 147 of the contact pieces 14 are bent upward against the restoring force of the contact pieces 14 and are guided onto the latching noses 410 until they lie flush with the recesses 1470. The contact legs 147 are then pressed back with the reset force of the contact piece, so that the notches 1470 surround the latching noses 410. Then, the contact member 14 is in the latched state R. In the latched state R, the contact leg 147 of the contact piece 14 presses with its restoring force against the contact and/or latching tab 41 of the contact counterpart 4 and contacts it in an electrically conductive manner.

In order to connect the contact partner 4 to the base plate 24 in an electrically conductive manner, the contact partner 4 has fixing

pins

431, 432 which are connected to the contact and/or latching means 41 by means of the connecting arm 42. The fixing pins 431, 432 are guided through the through-holes 240 of the base plate 24. The base plate 24 is designed as a circuit board and has a layer (not shown) which is provided as a shield of the mating plug connector 2. The fixing pins 431, 432 are soldered to this layer and are therefore connected to this layer in an electrically conductive manner. In the latched state R, the contact piece 14 and the contact counterpart 4 thus continuously connect the shield of the plug connector 1 and the shield of the counterpart plug connector 2 to one another. By the continuous connection of the shields to each other, the radiation or reception of electromagnetic waves can be reduced or even prevented.

In fig. 2, the wall 22 acts as a shield for the mating plug connector 2 instead of the base plate 24. The plug-in connection 100 of fig. 1 and 2 therefore differs in the shape of the contact partners 4 of the mating plug-in connector 2. Furthermore, the shielded connection 5 of the contact partner 4 to the wall 22 is produced here by means of a connection cable 52.

In contrast to the contact partner 4 of fig. 1, the contact partner 4 of fig. 2 has only one fixing pin 43, which is designed for plugging in a cable lug 51. The securing pin 43 is oriented away from the base plate 24 in the transverse direction 32. Furthermore, the connecting arm 42, which connects the contact and/or latching tab 41 of the contact partner 4 to the fastening pin 43 of the contact partner 4, is of significantly shorter design.

Wall tabs (not shown) are provided on the wall 22 and are also provided for plugging in cable lugs 53. The shielded connecting device 5 of the contact counterpart 4 with the wall 22 comprises a connecting cable 52 and two cable lugs 51, 53, which are respectively arranged on one end of the connecting cable 52. The cable lugs 51, 53 are each connected in an electrically conductive manner to the connection cable 52, in this case crimped. They are therefore configured as clamping sleeves. One cable lug 53 is fixed to the wall lug and the other cable lug 51 is fixed to the fixing lug 43 of the contact partner 4.

Fig. 2(b) shows the plug connection device 100 when the plug connector 1 is inserted into the mating plug connector 2. Here, the open latching end 1442 of the contact piece 14 is pressed upward along the contact of the contact counterpart 4 and/or the slope of the latching tab 41 until the latching nose 410 of the contact counterpart 4 can engage in the recess 1470 of the contact piece 14.

In the embodiment of fig. 3, a conventional screw is used as the contact 14. For this purpose, the base plate 13 of the plug connector 1 has a bend (not shown) for this purpose, so that it is oriented parallel to the wall 22 in the contact region 132. A plug housing 10 is arranged on the base plate and serves as a shielding element for the plug connector 1. A through-hole (not shown) is provided in the contact region 132, wherein the contact 14 passes through the through-hole.

In this embodiment, the contact elements 14 therefore do not act as latching means, but merely serve to electrically connect the shield of the plug connector 1 to the shield of the mating plug connector 2. In order to latch the plug connector 1 with the mating plug connector 2 in the assembled state M, an actuating element 16 is provided instead.

Thus, in fig. 3, the actuating element 16 acts as a catch. For this purpose, the actuating element has a latching element 1621 which is arranged on the latching arm 162 opposite the actuating surface 161. The latching element 1621 is designed here as a latching nose.

The contact partner 4 has a recess in comparison with the contact partner 4 of fig. 2. The indentation 411 is arranged to contact the counterpart element 411. In the fitted state M, the recess receives and makes electrical contact with the contact piece 14, which is designed as a plug or a screw, in order to establish an electrical connection between the shield of the plug connector 1 and the shield of the mating plug connector 2.

The contact partner 4 is inserted into the receptacle 211 of the mating plug housing 21. Here, the contact partner is arranged so as to be sunk in relation to the receptacle 211, so that a groove (not shown) remains in the receptacle 211 above the contact partner 4. This groove serves as an engagement portion for the latch nose 1621 of the operating member 16. The groove thus forms a latching counterpart element which interacts with a latching nose of the contact piece 16 serving as latching element 1621.

When the plug connector 1 is inserted into the mating plug connector 2, the contact 14, which is designed as a plug or a screw, is inserted into the recess 411 of the contact partner 4. At the same time, the latching arm 162 of the actuating element 16 is introduced into the mating plug connector 2 through the wall cutout 23 until it is arranged above the contact and/or latching tab 41 of the contact counterpart 4. Then, the latch nose 1621 of the operating member 16 engages and latches in the slot formed by the receiving portion 211. The actuating element 16 is then in the latched state R.

To disengage the latch, the actuating surface 161 of the actuating element 16 is pressed, so that the actuating element 16 is rotated in the direction of rotation 61. The actuating arm 162 and the latching nose 1621 rotate together with the actuating arm in the direction of rotation 61. Thereby, the latching nose 1621 is lifted out of the groove formed by the receiving portion 211. In this case, the actuating element 16 is moved from the latched state R into the unlatched state E. The plug connector 1 can then be moved from the mating plug connector 2 into the unassembled state U by moving counter to the insertion direction 30.

In contrast to fig. 2, a through-opening for fastening a cable lug 53 of the shielded connection device 5 is also provided on the wall 22 of the mating plug connector 2 of fig. 3. Thus, the cable lug 53 is screwed onto the wall 22 in fig. 3.

In the embodiment of fig. 4, instead of the through-opening, a wall lug is provided for fastening a cable lug 53 of the shielded connection device 5.

Fig. 5 shows a sectional view of an alternative embodiment of a plug-type connection 100 in (a) with a plug-type connector 1 and a corresponding mating plug-type connector 2 in the assembled state M, a detail of (a) in (b), and a contact spring 14 of the plug-type connection 100 in (c). Fig. 5(d) shows the plug-in connection in a perspective view in the assembled state.

In contrast to the embodiment of fig. 1 to 4, the contact spring is inserted as contact 14 onto the edge 231 of the wall cutout 23 provided in the wall 22. The contact spring 14 thereby establishes an electrically conductive connection between the base plate 13 and the wall 22, so that the shielding of the plug-in connection 100 is continuously present.

For this purpose, the contact spring 14 has two legs 142 lying opposite one another, which are provided for fixing the contact spring 14 to the wall 22. The legs 142 are bent substantially V-shaped, so that the intermediate space 140 between the legs 142 tapers. The wall 22 is pushed between the legs 142, wherein the legs are pressed apart against the restoring force of the spring 14, so that the spring 14 is clamped against the wall 22.

The legs 142 are connected to each other by an arcuate first spring portion 1411. The first spring portion 1411 is provided for contacting the circuit board 13. In addition, the spring 14 has a second spring portion 1412 extending from one of the spring legs 142 toward an open end (not shown). The first spring portion 1411 and the second spring portion 1412 are alternately disposed on the spring leg 142 at equidistant intervals (not shown) in the extending direction 31 of the spring 14. The second spring portion 1412 is shaped to be flatter than the first spring portion 1411 such that the wall 22 first strikes the second spring portion 1412 when inserted between the spring legs 142. The first spring portion 1411 is raised compared to the second spring portion 1412.

When inserting the plug connector 1 into the mating plug connector 2, the substrate 13 is placed between the contact spring 14, here the first spring portion 1411, and the base plate 24. As a result, the contact springs 14 press the circuit board 13 with their restoring force against the base plate 24 of the mating plug connector 2.

Embodiments of the plug-in connection 100 in which such or similar contact springs 14 are pushed onto the base plate 13 are also conceivable. An electrically conductive connection of the substrate 13 with the edge 231 of the wall cutout 23 or with the outer side (not shown) of the wall 22 can then be established.
