Description

The invention relates to a connector, a socket and a plug-in system with a connector and a socket.

The invention is in the field of connector technology. Connectors are used, for example, for making electrical contact and / or connection of communication lines or data lines and / or for supplying voltage to electrical and / or electronic devices and / or components. Often, connectors and sockets have multiple wires and are designed to connect multiple wires by plugging the connector into the socket. It may be necessary when connecting a connector to the socket or a socket or a socket to connect the wires of the connector in an exactly associated manner with the wires of the socket, as it would otherwise cause malfunction or damage the equipment thereby incorrectly connected can come.

Conventionally, connectors and / or sockets may provide mechanical elements, such as shapes, guide pins, notches or the like, to reduce the risk of improper insertion of the connector into the socket.

The document US 2015/0093922 A1 relates to a stackable plug with magnetic retention. The male connector has magnets arranged so that several of the male connectors can be plugged together so that they remain in contact. A detection circuit detects if connectors are stacked on top of each other.

The document DE 100 62 172 A1 relates to an electromechanical connection device with a current generator housing and with a current collector housing, each with flat contacts. The current transmitter housing is provided with a movable magnetic carriage with power contact points. The magnet carriage of the current encoder housing and the current collector housing are each provided with magnets. In the current generator housing, a permanent magnet is arranged on the side remote from the current collector housing side. The current generator housing and the current collector housing are forcibly connectable and detachable by a rotating device via a rotational movement. The flat contacts of the current encoder housing and the current collector housing are earlier in the connection of the current encoder housing and current collector and in their release longer in contact than the flat contacts of the current encoder housing with the current contact points on the magnet carriage.

The document DE 102 42 664 A1 relates to an electrical connection system with a power or data device which is connectable via input contacts with at least one current or pulse source, arranged in a transmitter housing and has magnets and contact elements. A power take-off or data pick-up device, which is electrically connectable to a consumer or consumer, is arranged in a slave housing and has at least one magnet and switching contact elements. By connecting the power or data supply device with the current collection or data pickup device, a current, pulse or data transfer between formed as a flat contacts with surface contact contact elements of the power or data device with the switch contacts of the power take-off or data pickup device can be produced, the magnets of the current decrease - or data generator means the magnet of the current collection or data pickup device are arranged opposite.

The document DE 195 12 335 C1 relates to an electromechanical connection device with a switching device which can be connected to a power source via power supply contacts and has switching magnets. A triggering device, which is provided with release magnets, is connectable to the switching device. Here, solenoids are brought from a rest position against a restraining force in a working position, wherein the contact of contact pairs and thus the electrical connection between the switching device and the triggering device is made. The solenoids and the tripping magnets are equipped with special coding. Several solenoids in the outer peripheral region of a working carriage are arranged at a distance from each other as segments. An equal number of tripping magnets with opposite polarity is also arranged as segments in the same circumferential region as the switching magnets in the tripping device.

The object of the invention is to provide an improved connector and an improved socket, which allow a correct insertion of the connector into the socket, without requiring increased attention or checking the correct orientation of the connector by the user.

This object is solved by the subject matters of the independent claims. Preferred embodiments are subject of the dependent claims.

• – zumindest zwei elektrische Kontakte; und
• – zumindest ein Steckverbinderorientierungselement, welches ausgelegt ist, beim Einstecken des Steckverbinders in den Sockel eine anziehende Kraft zwischen dem Steckverbinder und dem Sockel auszuüben und/oder ein Drehmoment um eine Steckerlängsmittelachse des Steckverbinders auszuüben und den Steckverbinder mitsamt der Kontakte derart um die Steckerlängsmittelachse zu drehen, dass in einem eingesteckten Zustand die Kontakte des Steckverbinders eine vorbestimmte Orientierung bezüglich des Sockels aufweisen.

In a first aspect, the invention relates to a connector for insertion into a socket, the connector comprising:

• - at least two electrical contacts; and
• At least one connector orientation element adapted to exert an attractive force between the connector and the socket upon insertion of the connector into the socket and / or to apply torque about a connector longitudinal center axis of the connector and to rotate the connector together with the contacts about the connector longitudinal center axis; that in an inserted state, the contacts of the connector have a predetermined orientation with respect to the base.

• – zumindest zwei elektrische Kontakte; und
• – zumindest ein Sockelorientierungselement, welches eingerichtet ist, beim Einstecken des Steckverbinders in den Sockel eine anziehende Kraft zwischen dem Steckverbinder und dem Sockel und/oder ein Drehmoment um eine Sockellängsmittelachse auszuüben und den Steckverbinder mitsamt der Kontakte derart um die Sockellängsmittelachse zu drehen, dass in einem eingesteckten Zustand die Kontakte des Steckverbinders eine vorbestimmte Orientierung bezüglich des Sockels aufweisen.

In a further aspect, the invention relates to a socket for receiving a connector, the socket comprising:

• - at least two electrical contacts; and
• - At least one socket orientation element, which is adapted when inserting the connector into the socket an attractive force between the connector and the socket and / or a torque to exert a Sockellängsmittelachse and turn the connector together with the contacts around the Sockellängsmittelachse such that in one plugged state, the contacts of the connector have a predetermined orientation with respect to the base.

In a further aspect, the invention relates to a plug-in system comprising a plug connector according to the invention and a socket according to the invention.

The invention offers the advantage that the plug connector when plugged into the socket automatically assumes the correct, predetermined orientation, without the user must turn the connector before plugging the connector, the connector in the correct, predetermined orientation. In other words, the plug rotates independently relative to the socket in the correct position or orientation. In particular, the predetermined orientation may correspond to a use orientation or position of the connector in which the contacts of the connector in the inserted state meet with the corresponding contacts of the socket and thereby the correct wires or wires are mechanically and / or electrically connected.

Thus, using the invention, it is possible to insert the connector into the socket also in an orientation different from the orientation of use, since the connector is in any case guided by the orientation elements, i. H. is rotated by the connector orientation element and / or the socket orientation element in the required orientation to take the predetermined orientation and to contact the socket in a correct manner. Thus, unlike conventional connectors, such as a bayonet lock, it is not necessary for the user to insert the plug into the socket in a well-defined orientation to allow proper contact. Rather, the user of the invention, the orientation and / or verification effort is removed, so that a connection in a very short time and without increased attention is possible.

The invention thus offers advantages, especially for such uses, in which an incorrect insertion of the connector would be particularly disadvantageous, for example due to incorrect polarity of the contacting and damage occurring as a result. Also, the use of the invention is particularly advantageous in environments and / or situations in which the user often has to deal with high time pressure or other stresses and therefore can not afford increased attention and / or time to verify the correct orientation of a male connector such as in operating rooms, in intensive care units and / or in medical practices. Even in environments in which due to frequent relative movements of the connector and the socket plugging is difficult, such as in moving vehicles, the invention can reduce the effort required to insert the connector. For example, use in or on equipment often used in ambulances and / or rescue helicopters may be particularly advantageous.

The attractive force between the connector and the socket, which is exercised by the at least one connector orientation element and socket orientation element, preferably not only contributes to the independent rotation of the connector relative to the socket, but can also serve to secure the connector or a secure to secure fit in the socket when the connector is plugged into the socket. In other words, the connector orientation element and / or socket orientation element can also serve to stabilize the plug-in system according to the invention when the plug-in connector is plugged into the socket.

Preferably, the connector orientation element and / or socket orientation element is designed such that it exerts both an attractive force between the connector and the socket and also exerts a torque on the plug connector relative to the socket. The attractive Force has a component parallel to the connector longitudinal central axis and optionally may also have a component perpendicular to the connector longitudinal central axis. The attractive force acts at least partially, preferably exclusively, in the plugging direction, ie in the direction in which the plug connector is to be inserted into the socket. The torque, however, preferably acts perpendicular to the direction of insertion, so that the torque causes a rotation of the connector to the Steckerlängsmittelachse. The plug longitudinal center axis preferably runs parallel to the plug-in direction.

The connector is preferably designed to turn the connector itself when plugged into the socket itself in the predetermined orientation, if the orientation of the connector with respect to the socket more than 0 °, optionally more than 5 °, further optionally more than 10 °, on optionally more than 30 °, further optionally more than 60 °, further optionally more than 90 ° and / or not more than 180 °, optionally not more than 120 °, further optional not more than 90 °, further optional not more than 60 ° , further optionally not more than 30 ° deviates from the predetermined orientation.

The at least one connector orientation element and / or base orientation element preferably has at least one magnet. The attractive force and / or the torque is preferably caused by a magnetic force caused by the magnet. In particular, for exerting a torque on the connector about the plug longitudinal center axis of the at least one magnet away from the plug longitudinal center axis, d. H. not in the center of the plug when viewed from the insertion direction, be arranged so that the magnetic force does not attack in the geometric center and / or not in the center of gravity of the connector.

The at least one magnet preferably comprises a permanent magnet, even if the use of electromagnets with a suitable voltage supply is possible in principle. In the case of a permanent magnet, various materials may be used, such as ferromagnetic materials and / or ferrites. Materials are preferably used which are inexpensive and have a high degree of magnetization, such as iron, cobalt and / or nickel. Permanent magnets which include neodymium, such as neodymium-iron-boron (NeFeB) permanent magnets, are preferably used. Particular preference is given to using conventional, commercially available permanent magnets, for example with a strength of the material identification class N45.

In particular, the at least one connector orientation element and / or socket orientation element exerts the attractive force between the connector and the socket even if the connector already has the predetermined orientation with respect to the socket. In other words, in cases where the connector already has the predetermined orientation with respect to the socket or the usage orientation, there can be only an attractive force between the connector and the socket, without an additional torque being exerted about the connector longitudinal center axis. If, on the other hand, the plug connector in its initial plug position has a different orientation than the predetermined orientation, then the plug connector orientation element and / or socket orientation element exerts the torque between the plug connector and the socket in order to reduce or eliminate the deviation from the predetermined orientation.

Preferably, the connector and the socket each have at least two electrical contacts. The connector may in particular also have exactly two electrical contacts, or also have three or more electrical contacts. Also, a connector with only one contact is conceivable, which could be important, for example, in a case in which a correct orientation of the contact is crucial.

Further, the connector may also include a plurality of connector orientation elements and / or socket orientation elements. In particular, the connector, for example, have exactly two magnets, which are preferably arranged anti-parallel to each other. Antiparallel means that the axes of the magnets, which are antiparallel to each other between the respective magnetic north pole and south pole, d. H. the axis between the north and south pole of a magnet is rotated by 180 ° against the corresponding axis of the other magnet and the magnets are thus arranged oppositely directed.

Preferably, the connector has a front cover on a contact side. The contact side can be the side of the connector in the insertion direction, which faces the socket when plugged. Preferably, the at least two electrical contacts of the connector are arranged on the contact side of the connector and extend away from the contact side or contact surface. In particular, the contacts may be formed as pins, which extend in the insertion direction and / or parallel to the connector longitudinal central axis. The base can, for example, for each pin or pin of the connector have a socket, in which the respective contact pin is plugged in plugging the connector into the socket.

Furthermore, the at least one connector orientation element is also preferably arranged on the contact side of the connector. For example, the at least one connector orientation element may be mounted on the front cover and / or under the front cover and / or covered by the front cover. Preferably, however, the attraction force of the connector orientation member through the front cover and at least partially in the direction of insertion, so that the base of the attraction force is reached before the contacts of the connector to the socket in contact.

Alternatively or additionally, the at least one base orientation element may comprise at least one magnet. Such a magnet can in particular have the same or similar properties as the properties of a connector orientation element formed in the connector. Both the plug connector and the socket preferably have plug connector orientation elements or base orientation elements, in particular magnets. Particularly preferably, these are arranged such that the attractive forces and the torque, which are caused by the magnets can rotate the connector around the connector longitudinal central axis, so that it assumes the predetermined orientation and then the connector in the predetermined orientation attached to the socket or is locked. This can be done for example by snapping and / or snapping. The magnets are therefore particularly preferably arranged in such a way that the magnets in the connector are arranged in the predetermined orientation on respectively one of the magnets of the base and / or adhere there. This can be achieved, for example, by considering the respective magnets in the socket and in the plug-in connector, ie in a projection perpendicular to the plug-in direction. H. each a connector orientation element and a base orientation element, fall on each other, but each oriented in anti-parallel to each other. In particular, can be prevented by inserting the connector into the socket in one of the predetermined deviating orientation by changing antiparallel orientations of the magnets in each case in the socket and in the connector.

In other words, the connector system is preferably configured such that the connector and the socket each have at least one magnet, wherein the respective magnets are arranged with opposite poles to each other, so that the magnets exert an attractive force between the connector and the socket to the Turn connector in the predetermined orientation with respect to the base. Preferably, the connector and the base each have two magnets, wherein the colliding upon insertion magnets in the connector and the base are arranged in anti-parallel to each other.

The contacts may be formed as contact pins and / or as surface contacts. For example, the plug connector and / or the socket may have contact pins or contact pins and / or contact sockets. The contacts may also be resiliently mounted to produce a particularly efficient mechanical and / or electrical contact. In the contact region, the contact pins preferably have a thickness between 0.05 mm and 10 mm, more preferably between 0.1 mm and 5 mm, even more preferably between 0.2 mm and 4 mm, more preferably between 0.3 mm and 3 mm, most preferably between 0.4 mm and 2 mm. Preferably, the contact pins have a length between 1 mm and 50 mm, more preferably between 2 mm and 40 mm, even more preferably between 3 mm and 30 mm, most preferably between 5 mm and 20 mm.

Particularly preferably, the predetermined orientation is predetermined such that upon insertion of the connector into the socket in the predetermined orientation, the at least two electrical contacts of the connector are electrically connected to the at least two electrical contacts of the socket according to a predetermined assignment. In this way, an electrical and / or mechanical contacting of the connector and the socket can be achieved with a correct polarity.

In addition, the connector and / or the socket may further comprise a thread, which is adapted to assist or at least partially cause the rotation of the connector about the connector longitudinal central axis and / or the Sockellängsmittelachse upon insertion of the connector. This can serve, for example, as support in the sense of a guide rail. For example, the connector and / or the socket may have a pin or pin which engages in such a thread upon insertion of the connector in the socket.

The invention will be described in more detail below with reference to exemplary embodiments shown in the figures, without, however, being restricted to them. Individual features of the embodiments described in the figures can be combined with other embodiments. Show it:

1A and 1B a perspective view of an inventive Connector in a preferred embodiment with a front cover ( 1A ) and without front cover ( 1B ) in a frontal view obliquely from the front;

2 a perspective view of a connector according to the invention in the preferred embodiment from above;

3A and 3B perspective views of a connector according to the invention in the preferred embodiment, when the connector is inserted in the predetermined orientation in a socket ( 3A ) and a connector which is inserted in an orientation deviating from the predetermined orientation in the base ( 3B );

4 a perspective view of a connector according to the invention in the preferred embodiment without housing and without wiring;

The embodiments shown in the following figures have partly identical or similar elements, which, if present, are always provided with the same reference numerals in the figures. In order to avoid unnecessary repetition, in the description of some figures a further explanation of the elements is dispensed with, although the explanations may also be applicable to these figures.

1A shows a connector 10 according to a preferred embodiment of the invention in a perspective view obliquely from the front. In particular, a connector housing 12 shown in which the contacts 14 wired or wired. The two connector orientation elements 16 are in 1A not shown, as these in the embodiment shown by the front cover 18 are covered. The connector housing 12 and the front cover 18 can be configured and arranged such that the connector 10 is protected against the penetration of foreign bodies and / or liquids and / or moisture. In particular, also the connector housing 12 the cable 20 surround flush, so also at the interface between the opening of the connector housing 12 on which the cable 20 in the interior of the connector housing 12 is protected from the penetration of foreign bodies and / or liquids and / or moisture. This has the advantage of wiring the contacts 14 with the individual wires or lines 22a and 22b of the cable 20 is protected from foreign bodies and / or liquids and / or moisture and thus the risk of unwanted short circuits and / or corrosion is reduced. For example, the connector may be designed to provide protection against debris and liquids in accordance with the IP67 standard.

Also the front cover 18 , in particular the cut surfaces to contacts 14 which are formed in the embodiment shown as contact pins can be formed fluid-tight. The contacts 14 extend away from the contact page 18a or from the front cover 18 of the connector 10 , through which the front cover 18 a contact side surface is formed, which faces in the plugging direction SR, as in 2 is shown.

Furthermore, the in 1A shown embodiment of the connector according to the invention 10 at the top of the connector housing 12 a positioning mark 24 which may serve to provide a user with the correct positioning and / or orientation of the connector 10 for insertion in a socket 28 (shown in 3A and 3B ), although according to the present invention correction of deviating orientations of the connector 10 when plugged in by the connector 10 and / or the pedestal 28 at least partially automatically. The positioning mark 24 is formed in the present embodiment as an arrow-shaped notch. However, the positioning mark 24 also have a different design and / or be printed or glued example.

In addition, according to the embodiment shown, the plug housing 12 on the outside a surface structuring 26 on. This surface structuring 26 can serve, for example, the connector housing 12 To design particularly handy, so that an accidental slipping of the connector housing 12 is prevented from the hands of a user while gripping. Particularly advantageous is the surface structuring 26 , If this is at least partially formed transversely or even perpendicular to the insertion direction SR, as in the case shown, since in this case when pushing or pressing the connector 10 in the direction of insertion SR or when pulling the connector against the insertion direction SR, for example, from a socket out, is made easier without the fingers or hands of the connector housing 12 slipping.

The contacts 14 are formed in the embodiment shown as elongated contact pins. However, this is not mandatory. The contact pins may, for example, have a length of not more than 30 mm, preferably not more than 20 mm, more preferably not more than 10 mm, most preferably not more than 5 mm. The contact pins may also have a length of at least 20 mm, preferably at least 10 mm, more preferably at least 5 mm, most preferably at least 1 mm. The contact pins may further have a thickness of not more than 10 mm, preferably not more than 8 mm, more preferably not more than 5 mm, most preferably not more than 3 mm. The contact pins may further have a thickness of at least 0.5 mm, preferably at least 1 mm, more preferably at least 2 mm, most preferably at least 5 mm.

Alternatively or additionally, the contacts 14 also have a different shape. For example, the contacts 14 be formed as a flat contact pads, which, for example, not more than 5 mm, preferably not more than 3 mm, more preferably not more than 2 mm from the contact surface or contact side 18a extend away. Furthermore, the contact pads can be flush with the front cover 18 be formed, or at least 0.5 mm, preferably at least 1 mm, more preferably at least 2 mm, most preferably at least 3 mm from the contact side 18a extend away.

For example, the contacts 14 in their extent parallel to the front cover 18 have a greater extent than perpendicular to the front cover 18 , in particular in the plugging direction SR. Particularly flat contacts 14 , For example, contact pads, thereby advantageously a particularly efficient rotation of the connector 10 by the at least one connector orientation element 16 (please refer 1B ), since due to the small length of such contact pads of the connector 10 especially close to the pedestal 28 can be brought without mechanical contact with the contacts 14 of the plug with the socket a rotary movement of the connector 10 impaired. For example, the contact pins may be spring-loaded.

In addition, the connector 10 not limited to contacts 14 to show which are formed as contact pins, but may alternatively or additionally, contacts 14 have, which are designed as contact sockets (not shown). It is particularly advantageous if the for the connector 10 provided socket 28 (not shown) for each contact of the connector 10 a complementary contact 14 at the appropriate location. In particular, it is advantageous if for each contact pin on the connector 10 or at the base 28 a corresponding contact socket in the other component, ie connectors 10 or socket 28 , is available. Only contact sockets can be formed without a complementary contact pin, as they do not plug in between the connector 10 and the pedestal 28 extend and thus plugging in the absence of complementary contact 14 would not hinder.

Further, the number of contacts 14 of the connector 10 not on two contacts 14 limited. For example, more than two contacts 14 circular, in one or more rows, spirally, or arranged in a different geometry. For example, the connector 10 at least eight, preferably at least five, more preferably at least three, most preferably at least one contact 14 exhibit. Furthermore, the connector 10 at most 2, preferably at most five, more preferably at most eight, most preferably at most twelve contacts 14 exhibit.

1B shows the connector 10 according to the in 1A shown embodiment without the front cover 18 , causing the under the front cover 18 arranged connector orientation elements 16 can be seen. In the embodiment shown, the connector 10 two connector orientation elements 16 on, which are each formed as a permanent magnet. In particular, the front sides of the permanent magnets, which when applying the front cover 18 are arranged directly below this, formed as a magnetic pole of the respective permanent magnet. In the embodiment shown, the two connector orientation elements 16 designed as a permanent magnet, which are arranged antiparallel to each other. Ie. during one of the permanent magnets with its magnetic south pole of the contact side 18a is facing, the other permanent magnet with its magnetic north pole of the contact side 18a facing.

By this arrangement and the corresponding arrangement of any permanent magnets, which in an associated socket 28 are formed, it can be ensured that the connector 10 not in a wrong orientation in the socket 28 can be inserted, as in a rotation of the connector 10 for example, 180 ° to the predetermined orientation of use, the connector orientation elements 16 or permanent magnets of the connector 10 and the pedestal 28 would repel each other while they would attract each other at a correct orientation according to the predetermined orientation. By means of such an arrangement of the connector orientation elements 16 It is also possible to generate a torque about the plug-in direction SR or plug longitudinal center axis at a different orientation than the predetermined orientation, so that the plug connector 10 is rotated in the predetermined orientation and in the predetermined orientation with the base 28 combines.

For example, the connector 10 and the pedestal 28 be designed such that a tensile force of, for example, at least 1 N is required to the plugged connector to be detached from the socket. For example, the connector 10 and the pedestal 28 Also be designed such that a tensile force of, for example, less than 100 N is sufficient to release the plugged connector from the socket.

2 shows the connector 10 according to the already in 1A and 1B shown embodiment in plan view. In particular, the plug-in direction SR is indicated. According to this embodiment, the plugging direction SR extends along the plug longitudinal center axis. The position mark 24 indicates to the user in which direction the plug-in direction SR extends, that is, in which direction the plug connector 10 in a socket 28 for proper use. Furthermore, in 2 clearly recognizable that according to this preferred embodiment, the surface structuring 26 of the connector housing 12 runs perpendicular to the insertion direction SR. The contacts 14 extend according to this preferred embodiment, both parallel to the insertion direction SR and the plug longitudinal center axis. This has the advantageous effect that the extension direction of the contacts 14 remains the same, even if by a through the connector orientation elements 16 caused torque the connector 10 relative to the socket 28 turns around the plug longitudinal axis.

3A shows a perspective view of the connector 10 According to the embodiment shown in the previous figures in a state in which the connector 10 in a socket 28 is plugged in. It can be seen in particular that the base 28 a positioning mark 24 which of the positioning mark 24 on the connector 10 is designed accordingly as an embossing in arrow shape. With correct insertion of the connector 10 show the arrowheads of the two positioning marks 24 opposite each other and illustrate in this way that the connector 10 in the predetermined position and orientation in the socket 28 was inserted. In other words, the matching, relative positioning of the positioning mark 24 on that the connector 10 is inserted in its intended use position in the socket.

Additionally, the plug and / or socket may include a mechanical element (not shown) which, in addition to the features of the invention, includes plugging the connector 10 prevented in a wrong orientation. For example, such a mechanical element as a pin, a nose, a groove, a notch, as a combination of tongue and groove, or the like may be formed, which is an incorrect insertion of the connector 10 difficult or even completely prevented. In particular, such a mechanical element may be formed, an insertion of the connector 10 in a direction rotated by 180 ° from the predetermined orientation to prevent orientation.

3B shows a connector 10 in a different orientation from the predetermined orientation. This is particularly evident from the fact that the positioning mark 24 on the connector 10 and the positioning mark 24 at the base 28 are not opposite and facing each other, but that there is an angular offset between the two. In this case, a torque M acts on the connector 10 , wherein the direction of rotation of the torque M is exemplified by a dashed arrow. That on the connector 10 acting torque M is directed so that it is designed to reduce the deviation of the orientation of the predetermined orientation.

4 shows a perspective view of the connector 10 according to the embodiment shown in the previous figures without the enclosing connector housing 12 to the elements of the connector therein 10 to be able to recognize. It can be seen that the connector 10 a first plug body 30a and a second plug body 30b having. The two plug bodies 30a and 30b serve to the connector 10 to stabilize, in particular against external pressure on the connector housing (not shown) 12 , which on the plug bodies 30a and 30b and also serves the contacts 14 and the connector orientation elements 16 to hold in position and in a stable manner against each other. The two plug bodies 30a and 30b are shown transparent for explanation, in order to recognize the components therein, without the plug body 30a and 30b However, they must be transparent.

In 4 is recognizable that the contacts 14 in the longitudinal direction, ie in the direction of the plug-in direction SR or parallel to the connector longitudinal central axis, by corresponding recesses in the housing bodies 30a and 30b run and at the contact page 18a of the connector 10 from the second plug body 30b emerge in the direction of insertion. Furthermore, at the contact page 18a the second plug body 30b be closed and a front cover 18 form, which, for example, in 1A is shown. On the contact page 18a facing away from the rear contact sections 34 from the first plug body 30a out, which, however, still within the connector housing 12 a complete connector 10 are located. The connection sections 34 serve for wiring or cabling of the respective contacts 14 to about the contacts 14 with the appropriate lines 22a respectively. 22b of the cable 20 connect to.

The connector orientation elements 16 are formed in the embodiment shown as permanent magnets, which have an elongated shape along the connector longitudinal central axis. In this case, the permanent magnets each have a magnetic pole on the contact side and the respective magnetic opposite pole on the back 36 of the respective connector orientation element 16 , The connector orientation elements 16 are arranged such that the permanent magnets are arranged antiparallel to each other. According to the embodiment shown, the permanent magnets are formed symmetrically such that they are in both directions in the plug body 30a and 30b can be inserted, so for different connectors 10 as required, the permanent magnets can be used with the magnetic south pole or north pole on the contact side, without this being a structural modification of the plug body 30a and or 30b or the plug housing required.

The first plug body 30a and the second plug body 30b can thereby as shown through recesses for the connector orientation elements 16 have, ie on the contact side 18a and also have openings on the back, or on the back and / or the contact side 18a be closed and enclose the connector orientation elements partially or completely. In particular, when the plug body 30a and 30b the connector orientation elements 16 enclose, the plug body should 30a and 30b and the connector housing 12 be formed of a non-magnetic or only weakly magnetic material to a shield or deflection of the connector orientation elements 16 to avoid generated magnetic field.

Furthermore, the embodiment shown has a sealing ring 32 on which serves to the connector housing 12 or the connector 10 to protect against the penetration of foreign bodies and / or fluids.
