Description

The invention relates to a method for producing a plug-in contact connection between a first and a second plug contact element. Furthermore, the invention relates to connector devices and a connector pair comprising the connector device and a mating connector device.

Such methods and devices are known and are used in various applications, for example for the production of plug-in contact connections in the telecommunications sector, in the energy distribution of power generation plants and in the motor vehicle sector:
For example, a connector for flexible ribbon conductors is made DE 100 65 354 A1 known. This connector has a connector housing with contact elements mounted therein and a mating connector housing supporting a ribbon conductor. When mating the two housings, the electrical contact connection is made. For fixing the ribbon conductor in the ribbon conductor mating connector housing a pawl device is provided which does not hinder the insertion of the ribbon conductor to the stop and can only be effective when the ribbon conductor is properly fixed in the housing. The pawl means is arranged so as to hinder the mating plug from being inserted into the plug housing when the ribbon conductor with the pawl means is not properly fixed (go-nogo means).

Another possibility for securing an electrical plug connection is a locking device in the form of a mounting receipt. Such a device is off DE 103 46 367 A1 known. The freely rotatable HF-angle connector described therein comprises a housing and at least one contact, wherein the contact is mounted in the housing by means of an axial securing in the housing. The assembly receipt sits on a latching arm and is displaceable in the insertion direction. To lock the connector, the assembly receipt is moved back in the direction of the plug and for unlocking in the original position. The assembly receipt serves for fixing, for example, a latching arm by means of which the angle plug connector can be fastened with a plug via a latching lug attached to it.

To stabilize the sliding movement of a movable contact element in a connection terminal in a pressure contact for heavy current applications is in DE 196 34 434 C2 described a plug connection between the pressure contact and a fixed counter contact. For this purpose, a contact device is provided, which has an elastic and electrically conductive bearing and contact band, which is arranged for making contact between the connection terminal and the contact element. By the coming into contact with the fixed mating contact and acted upon by a spiral spring in the connection terminal mating contact thus a movement perpendicular to the axis of the movable contact element is prevented, so that a secure contact between the movable contact element and the fixed mating contact is achieved. The pressure contact is suitable by the action of the coil spring, moreover, to produce a sufficient contact pressure.

To reduce the insertion force required to make a plug connection, for example, in US 5,235,743 A a surface coating on a plug and a mating connector receptacle described. The plug and the plug receptacle are for this purpose coated with a mixture of Teflon and a powder of tin, nickel or the like.

Out DE 10 2004 002 402 B3 a high-current-load connection device is described with a contact sleeve, which allows a reliable and permanent electrical Vielpunktkontaktierung between an internally disposed pin member and an externally arranged socket with simultaneous, mechanical tolerance compensation under a variety of practical conditions. For this purpose, the contact sleeve at an end face on an annular collar portion around its outer circumference around longitudinal slots by separate, elongated spring elements are arranged, which are pre-bent in a desired contacting area on the pin member to the inside. This creates a contact seat there. On the outer side of the contact sleeve at the desired contacting area, a spring ring overrides the spring force of the spring elements.

Another embodiment of a contact piece for an electrical connector is in DE 100 05 297 A1 described. For ease of manufacture, the contact piece is formed from a one-piece contact element and a sheath. The contact element has both a connection region and a cage-like, permanently twisted in the circumferential direction bushing part with a plurality of axially parallel before the twisting extending, mutually spaced lamellae. The contact piece is made of an electrically conductive and permanently elastic band material. The sheath is formed in the form of a pushed over the contact region of the contact element protective sleeve made of a corrosion-resistant material of high strength. In such a contact, the contact pin is in the inserted state securely on a plurality of strip-shaped Slats of the contact piece, which is why this type of connector is safe to use even with relatively high electrical load.

Out DE 10 2005 040 952 A1 Furthermore, a zero-force electrical connector with a surrounding housing and with an aggregate connection is known. The surrounding housing has receptacles for several sleeve contacts. The sleeve contacts each have a contact blade forming main body and a sliding relative to the main body clamping sleeve. The aggregate connection has plug contacts contacting the sleeve contacts. A fixing housing can be latched to the surrounding housing in a pre-locking position and in a final locked position. When attached to the surrounding housing, the unit connection releases a locking device of the fixing housing on the surrounding housing and transfers the fixing housing from the pre-locking position into the final locked position. At the same time, the clamping sleeves are displaced along the base body of the sleeve contacts, and the clamping sleeves press the contact blades against the plug pins of the unit connection. It is stated that the contact force required for secure contacting of the sleeve contacts is produced by the attachment force of the unit connection to the connector part and that only after the connector pins of the unit connection are inserted into the sleeve contacts. However, a disadvantage of this connection device is that it is not guaranteed that the connection is also mechanically secured when the electrical contact is made. For this reason, the electrical connection in an unfavorable case can not properly come about and have a large contact resistance, which leads to damage or even destruction.

Out DE 10 2008 061 934 A1 is a single pole high current connector for wind turbines known. A plug and a coupling contact are housed in a plug housing or a coupling housing. The connector is provided with a latching mechanism that produces an audible click when the connector and coupling are fully mated together. Ring-shaped spring elements, which are clamped in the inserted state between the plug contact and the coupling contact, form the actual electrical contact.

For high-current applications, it is important that the electrical contact resistance between the contact partners as low as possible and the electrical connection must be made reliably reliable. For high-current connections, special attention is paid to low electrical resistance. Electrical losses occurring at the electrical connection points reduce the efficiency of the plug connection and cause a contact heating, whereby adjustments of the line cross-section and, if appropriate, the production of finished contact surfaces may be required. The contact resistance can be advantageously influenced by the selection of a suitable contact material whose properties affect the conductance, the material thickness and the number of contact points.

However, the known connectors have the disadvantage that a secure contact with high current applications can not be readily achieved and possibly only if only a few contact connections must be made simultaneously. If, however, a multi-pin connector are made, it may be necessary under circumstances that considerable effort is required to plug the contacts into each other. In constructions of connector components that require in such cases no high force when plugging, the reliability of the connector may not exist, so that the efficiency of the connector is low and the connection due to the resulting high contact resistance due to intense heating may even destroyed or at least can be damaged.

The present invention is therefore based on the object, measures for secure contact, which is made by simple plug connection between the contact partners, to find in high-current applications.

This object is achieved by the method for producing an electrical plug contact connection according to claim 1, the connector devices according to claims 7 and 11 and the connector pair comprising the connector device and a counter-connector device according to claim 15. Preferred embodiments of the invention are specified in the subclaims.

Insofar as below in the description and in the claims, individual elements of the invention forming objects, devices, devices, arrangements and means are given in the singular, for example, a first plug contact element or a second plug contact element, so are each including the corresponding terms in the plural , For example, a plurality of first plug contact elements or a plurality of second plug contact elements, and vice versa, unless expressly stated otherwise. Therefore, these terms should be replaced by "at least one" or "at least one".

The inventive method is used to produce an electrical Plug contact connection between a first plug contact element and a second plug contact element, wherein the first plug contact element is part of a connector device and the second plug contact element part of a mating connector device.

According to the present invention, the first plug-in contact element and the second plug-in contact element come into contact only after completion plugging operation, so that an electrical contact between the two elements is made dependent on an executed locking of the connector device with the mating connector device.

The method according to the invention comprises the method steps listed in the following order, it being possible additionally for further method steps to be provided before, after and / or between the specified method steps:

• (a) providing the first plug contact element that is in a spatial configuration that does not allow electrical contact with the second plug contact element;
• (b) connecting the connector device to the mating connector device, wherein the first and second mating contact elements remain in the spatial configuration that does not allow electrical contacting;
• (c) Mechanically locking the connector device to the mating connector device and
• (D) making electrical contact of the first plug contact element with the second plug contact element, while the connector device and the counter connector device are mechanically locked / locked together; to produce the electrical contact, the first plug contact element is deformed.

The plug contact device is complementary to the counter plug connector device having the second plug contact element. Preferably, the connector device is formed by a plug housing and the mating connector device by a connector receptacle. In principle, the connector device can also be formed by a plug receptacle and the mating connector device by a plug housing. The plug housing is inserted to make the electrical contact in the connector receptacle. The second plug contact element is preferably formed by the male part of the plug connection and therefore by a contact pin. The first plug contact element is preferably formed by the female part of the plug connection and therefore by a contact opening. In principle, these two configurations can also be reversed (the first plug contact element by a contact pin and the second plug contact element by a contact opening). Both connector devices also have housing parts, such as for electrical insulation and mechanical protection to the outside. In addition, the two devices each comprise an electrical contact transition to an electrical line, for example to a cable or a ribbon cable or to conductor tracks of a printed circuit board.

More preferably, mechanically locking the connector device to the mating connector device according to step (c) comprises moving the connector device relative to the mating connector device to a latched position such that the connector device and the mating connector device lock together without electrical contact between the connector first and the second plug-in contact element is produced. So that the contact partners (first and second plug contact element) do not touch each other and an electrical contact is made inadvertently, a sufficient distance between them and a suitable guide is to be provided.

• d2) Überführen des ersten Steckkontaktelements in eine einen elektrischen Kontakt mit dem zweiten Steckkontaktelement herstellende räumliche Konfiguration.

More preferably, the production of an electrical contact of the first plug contact element with the second plug contact element according to method step (d) preferably comprises

• d1) moving the connector device and / or one held by the connector device sliding element relative to the mating connector device beyond the latching position and
• d2) transferring the first plug-in contact element into a spatial configuration producing electrical contact with the second plug-in contact element.

• e) Bewegen der Steckverbindervorrichtung und/oder des Schiebeelements zurück in die Verrastposition.

With further preference, the following process step follows at process step (d):

• e) moving the connector device and / or the sliding element back into the latching position.

The method according to the invention and the connector devices according to the invention have significant advantages over conventional methods and devices for producing a plug-in contact connection:
By the plug contact connection is not already made during the connection of the connector device with the mating connector device but only when both parts are firmly connected together, on the one hand, the force required for the connection can be limited exclusively to the fact that the two parts be mechanically locked together. An additional force for sliding electrical connection of the two plug contact elements during the telescoping of the two devices with each other is therefore not required. Therefore, no costly measures to reduce the sliding friction of the contact surfaces such as in the plug contact of US 5,235,743 A required. Even with complex multi-pin connectors, no significant insertion force is needed.

The inventive method and the connector devices according to the invention a safe energy transfer in the connector is also possible if it is intended for high current applications. This makes it possible, inter alia, that the invention is also used, for example, for plug connections for charging a battery of an electric vehicle at a charging station.

In a first method variant with a preloaded first plug-in contact element, this is locked in a prestressed state before the plug contact element is connected to the counter plug contact element. For this purpose, the contact area, the first plug-in contact element, expanded by external forces. Until the initially preloaded first plug-in contact element is relaxed, it remains widened, which ensures that the contact partners do not touch each other.

To transfer the first plug-in contact element into the electrical contact with the second plug-in contact element producing spatial configuration according to step (d2), the locking of the first plug contact element is canceled or even partially canceled. For this purpose, a targeted engagement is made in the connector device, so that relaxes the first plug contact element. As a result, the contact area can narrow, and the electrical contact can be made.

The first plug contact element is in the position in which it rests on the second plug contact element, no longer under tension or has only a residual stress on this residual voltage can also be used, for example, to automatically solve the two plug contact elements again from each other when the mechanical lock the connector device with the mating connector device has failed.

• (a) Bereitstellen des ersten Steckkontaktelements, das sich in einer ein elektrisches In-Kontakt-Bringen mit dem zweiten Steckkontaktelement nicht erlaubenden räumlichen Konfiguration befindet und das in einem vorgespannten Zustand verriegelt ist;
• (b) Verbinden der Steckverbindervorrichtung, insbesondere des Steckgehäuses, mit der Gegen-Steckverbindervorrichtung, insbesondere mit der Steckeraufnahme, d. h. bevorzugt wird das Steckgehäuse in die Steckeraufnahme eingesteckt; die beiden Steckkontaktelemente gelangen in der eingeführten Stellung aber noch nicht in einen elektrischen Kontakt miteinander;
• (c) Bewegen der Steckverbindervorrichtung gegenüber der Gegen-Steckverbindervorrichtung bis zu einer Verrastposition, sodass die Steckverbindervorrichtung und die Gegen-Steckverbindervorrichtung mechanisch miteinander verrasten und sie damit mechanisch verriegelt sind, ohne dass bisher ein elektrischer Kontakt zwischen dem ersten und dem zweiten Steckkontaktelement hergestellt wird;
• (d) Bewegen der Steckverbindervorrichtung und/oder eines von der Steckverbindervorrichtung gehaltenen Schiebeelements gegenüber der Gegen-Steckverbindervorrichtung über die Verrastposition hinaus; daraufhin wird die Verriegelung des ersten Steckkontaktelements aufgehoben, sodass das erste Steckkontaktelement in die den elektrischen Kontakt mit dem zweiten Steckkontaktelement herstellende räumliche Konfiguration überführt wird; dadurch wird ein elektrischer Kontakt zwischen dem ersten Steckkontaktelement und dem zweiten Steckkontaktelement hergestellt, denn das erste Steckkontaktelement kann aufgrund der Entriegelung durch Bewegung seine Spannung abbauen und dadurch mit dem zweiten Steckkontaktelement in Kontakt kommen;
• (e) Zurück gleiten der Steckverbindervorrichtung bzw. des Schiebelements zurück in die Verrastposition.

Thus, in the first method variant with a preloaded first plug-in contact element, the method according to the invention comprises the method steps listed in the following order:

• (a) providing the first plug contact element which is in a spatial configuration which does not permit electrical contact with the second plug contact element and which is locked in a biased state;
• (B) connecting the connector device, in particular of the plug housing, with the counter-connector device, in particular with the plug receptacle, ie preferably the plug housing is inserted into the plug receptacle; the two plug contact elements are not yet in electrical contact with each other in the inserted position;
• (c) moving the connector device relative to the mating connector device to a latched position such that the connector device and the mating connector device mechanically lock together and are mechanically locked thereto without previously making electrical contact between the first and second plug contact elements;
• (d) moving the connector device and / or a sliding member held by the connector device opposite the mating connector device beyond the locking position; then the locking of the first plug-in contact element is released, so that the first plug-in contact element is converted into the electrical contact with the second plug-in contact element producing spatial configuration; As a result, an electrical contact between the first plug contact element and the second plug contact element is produced, because the first plug contact element can break down due to the unlocking by moving its voltage and thereby come into contact with the second plug contact element;
• (e) Sliding back the connector device or sliding element back into the latching position.

Thus, the connector device is mechanically locked, and the electrical connection is made securely.

Thus, in this case, a biased first plug-in contact element is assumed whose voltage can be used for the production of the electrical plug connection when the first plug contact element is unlocked.

• (a) ein erstes von der Steckverbindervorrichtung gehaltenes elastisch verformbares Steckkontaktelement,
• (b) eine Vorspannvorrichtung zum Spannen des ersten Steckkontaktelements, sodass das erste sich in dem vorgespannten Zustand befindende Steckkontaktelement beim Verbinden der Steckverbindervorrichtung mit der Gegen-Steckverbindervorrichtung nicht in eine räumliche Konfiguration gelangen kann, die ein elektrisches In-Kontakt-Kommen mit dem zweiten Steckkontaktelement erlauben würde,
• (c) eine Auslösevorrichtung zum Lösen der Spannung des ersten Steckkontaktelements, sodass das erste und das zweite Steckkontaktelement in eine elektrische Kontaktstellung gelangen, und
• (d) ein Rastelement zum mechanischen Verrasten der Steckverbindervorrichtung mit der Gegen-Steckverbindervorrichtung, sodass die elektrische Kontaktstellung fixiert ist.

In a first variant of the connector device according to the invention, which is particularly suitable for carrying out the method according to the invention for producing the electrical plug contact connection in the first variant of the method, the connector device comprises a biased first plug contact element:

• (a) a first elastically deformable plug contact element held by the plug connector device,
• (B) a biasing device for tensioning the first plug contact element, so that the first in the prestressed state located plug contact element when connecting the connector device with the mating connector device can not get into a spatial configuration having an electrical contact with the second plug contact element would allow
• (C) a triggering device for releasing the voltage of the first plug-in contact element, so that the first and the second plug-in contact element come into an electrical contact position, and
• (D) a locking element for mechanically locking the connector device with the counter-connector device, so that the electrical contact position is fixed.

In a second variant of the method with a non-preloaded first plug-in contact element is this before connecting the connector device with the counter-connector device in an unbiased state. In this case, the contact force is generated only after fully closed connector. The first plug contact element is for making the electrical contact with the second plug contact element according to method step (d) in a the electrical contact with the second plug contact element producing spatial configuration and thereby transferred to a biased state. In order to keep the contact forces stable, a corresponding locking of the connector device with the counter-connector device is required. Until this Kontaktkraftarretierung is closed, the restoring forces cause the opening of the contact, whereby an improper mechanical contact is excluded. Thus, the voltage generated can be used to automatically disconnect the two plug contact elements again from each other when the mechanical locking of the connector device has failed with the mating connector device.

• (a) Bereitstellen des ersten Steckkontaktelements, das sich in einer ein elektrisches In-Kontakt-Bringen mit dem zweiten Steckkontaktelement nicht erlaubenden räumlichen Konfiguration befindet und in dieser Konfiguration verriegelt sein kann und das nicht vorgespannt ist,

• (c) Bewegen der Steckverbindervorrichtung gegenüber der Gegen-Steckverbindervorrichtung bis zu einer Verrastposition, sodass die Steckverbindervorrichtung und die Gegen-Steckverbindervorrichtung mechanisch miteinander verrosten und sie damit mechanisch miteinander verriegelt sind, ohne dass bisher ein elektrischer Kontakt zwischen dem ersten und dem zweiten Steckkontaktelement hergestellt worden ist,
• (d) Bewegen der Steckverbindervorrichtung und/oder eines von der Steckverbindervorrichtung gehaltenen Schiebeelements gegenüber der Gegen-Steckverbindervorrichtung über die Verrastposition hinaus; dabei wird entgegen der Spannung des ersten Steckkontaktelements eine Kraft auf dieses ausgeübt, sodass das erste Steckkontaktelement in die den elektrischen Kontakt mit dem zweiten Steckkontaktelement herstellende räumliche Konfiguration überführt wird; dadurch wird ein elektrischer Kontakt zwischen dem ersten Steckkontaktelement und dem zweiten Steckkontaktelement hergestellt; durch das Ausüben der Kraft auf das erste Steckkontaktelement kann das erste Steckkontaktelement vorgespannt werden; diese Kraft kann von der Steckverbindervorrichtung oder von einer mit der Steckverbindervorrichtung in Verbindung stehenden Verstellvorrichtung auf das erste Steckkontaktelement ausgeübt werden; und
• (e) Zurück gleiten der Steckverbindervorrichtung bzw. des Schiebelements in die Verrastposition.

Thus, in the second method variant with a non-preloaded first plug-in contact element, the method according to the invention comprises the method steps listed in the following order:

• (a) providing the first plug contact element that is in a spatial configuration that does not permit electrical contact with the second plug contact element and that may be locked in that configuration and that is not biased,
• (B) connecting the connector device, in particular of the plug housing, with the mating connector device, in particular with the plug receptacle, ie preferably the plug housing is inserted into the plug receptacle, without an electrical contact between the first and the second plug contact element comes about
• (c) moving the connector device relative to the mating connector device to a latched position such that the connector device and the mating connector device mechanically rust together and are thus mechanically interlocked with each other without electrical contact between the first and second plug contact elements made so far is
• (d) moving the connector device and / or a sliding member held by the connector device opposite the mating connector device beyond the locking position; In this case, a force is exerted on this against the voltage of the first plug-in contact element, so that the first plug-in contact element is converted into the electrical contact with the second plug-in contact element producing spatial configuration; thereby an electrical contact between the first plug contact element and the second plug contact element is produced; by exerting the force on the first plug contact element, the first plug contact element can be biased; this force can be exerted by the connector device or by an adjusting device connected to the connector device on the first plug contact element; and
• (E) Sliding back the connector device or the sliding element in the latching position.

Thus, the connector device is mechanically locked, and the electrical connection is made securely.

Thus, in this case, in contrast to the first-mentioned variant, a non-preloaded first plug-in contact element is assumed, wherein a mechanical stress is generated during the plugging process. According to the invention, part of the voltage can also be generated before the latching position is reached, namely during the connection of the connector device to the mating connector device, preferably during the insertion of the plug housing into the connector receptacle, according to method step (b).

• (a) ein erstes von der Steckverbindervorrichtung gehaltenes elastisch verformbares Steckkontaktelement,
• (b) eine Verstellvorrichtung zum Überführen des ersten Steckkontaktelements in eine räumliche Konfiguration, die es erlaubt, einen elektrischen Kontakt mit dem zweiten Steckkontaktelement herzustellen, sobald die Steckverbindervorrichtung mit der Gegen-Steckverbindervorrichtung vollständig verbunden ist, sodass das erste und das zweite Steckkontaktelement in eine elektrische Kontaktstellung gelangen, und
• (c) ein Rastelement zum Verrasten der Steckverbindervorrichtung mit der Gegen-Steckverbindervorrichtung, sodass die elektrische Kontaktstellung fixiert ist.

In a second variant of the connector device according to the invention, in particular for carrying out the method according to the invention for producing the plug-in contact connection in the second variant of the method is suitable, comprises the connector device with a non-biased first plug contact element:

• (a) a first elastically deformable plug contact element held by the plug connector device,
• (B) an adjusting device for transferring the first plug-in contact element in a spatial configuration, which makes it possible to make electrical contact with the second plug contact element, as soon as the plug connector device is fully connected to the mating connector device, so that the first and the second plug contact element in an electrical Get in contact position, and
• (C) a locking element for locking the connector device with the counter-connector device, so that the electrical contact position is fixed.

Preferably, the adjusting device is designed to generate a voltage of the first plug-in contact element. With the help of this voltage, the connector device of the counter-connector device can be automatically released again when the mechanical lock has failed.

Also according to the invention is a pair of connectors comprising the connector device according to the invention, preferably the plug housing, as well as the mating connector device, preferably plug receptacle. The counter-connector device can be latched to the connector device and has the second plug contact element, which can make an electrical plug contact connection with the first plug contact element of the connector device.

With the method and devices according to the invention, in particular, there is the possibility that the connection between the two plug contact elements automatically disconnects again, without an electrical contact has come about, if the mechanical locking between the plug device and the plug receptacle device is not reached. This means that an electrical contact between the two plug-in contact elements is produced only when the mechanical connection between the plug device and the plug receptacle device is made safe and reliable. A situation in which the electrical contact is made in spite of non-existing locking, so there may be problems in power transmission due to lack of fixed mechanical connection and then the connector may be damaged or even destroyed, is thus safely and reliably avoided. In particular, the contact forces required for the contact function can be used for electrically disconnecting incompletely closed plug connections. Particularly in the case of the second variant of the method and second variant of the device with non-preloaded first plug-in contact element, the voltage generated when the plug device is connected to the plug receptacle can serve as a force store for an automatic release of the two devices if the mechanical latching does not take effect. But even in the first variant of the method and the first device variant, when connecting the connector device with the counter-connector device, a force accumulator can be constructed, which leads to the automatic release of the two parts from each other when the mechanical interlock does not take place.

When connecting the connector device with the counter-connector device according to method step (b) and / or when establishing the electrical contact of the first plug contact element with the second plug contact element according to method step (d), a mechanical force can be generated, which counteracts the joining of the two parts. Thereby, the connector device and the mating connector device are then automatically separated again, and the electrical contact of the first plug contact element with the second plug contact element is not established when the mechanical locking of the connector device fails with the mating connector device according to step (c).

Thus, in addition to a minimized friction of the contact partner and a minimized fretting wear the security increased. This also maximizes the number of mating cycles.

The mechanical locking, in particular mechanical locking, of the connector device with the mating connector device, can in the usual way with first locking elements, such as detents, projections, springs, edges and / or blocks on one to be locked / latching device and corresponding second locking elements, for example, latching recesses or also latching lugs, projections, springs, edges and / or blocks on the other to be locked / latching device and that at the two devices to be connected in each case corresponding to each other. Alternatively or additionally, a rotary coupling with screw, bayonet and / or other connecting elements may be provided on the two devices to be connected, in each case corresponding to one another or, alternatively, a connection via snap closures or the like.

The tripping device according to the first variant of the connector device serves to release the voltage of the first plug contact element. Since the first plug contact element in this variant is in the position under a voltage in which it is not in electrical contact with the second plug contact element, the first plug contact element is held in this position by the biasing device. For the transfer of the first plug contact element in the position in which it comes into electrical contact with the second plug contact element, the biasing device must release the first plug contact element. For this purpose, the triggering device triggers the biasing device and thus triggers the voltage of the first plug-in contact element. The triggering device is thus coupled to the biasing device and adapted in terms of their design to the construction of the biasing device. The release of the biasing device can be done, for example, by moving the biasing device out of a holder in which it holds the first plug-in contact element under tension. The triggering device can thus be, for example, an actuator which shifts the pretensioning device in the release direction of the holder. Alternatively, the triggering device may also be an acting in one direction of rotation actuator, which converts a biasing device in a rotational direction in a release position.

The trip device is in turn triggered by the connector device being locked / latched to the mating connector device and optionally moved beyond the latch / latch position. For example, the triggering device can be directly actuated by the movement of the connector device relative to the mating connector device beyond the locking / Verrastungsstellung, such as by a mechanical contact of the connector receptacle with the triggering device in the connector housing, so that the triggering device is released from a locked position.

In a first preferred embodiment of the connector device according to the invention according to the first variant, the first plug contact element is formed by at least one contact spring, which rests in the relaxed state on the second plug contact element, d. H. when the locking of the contact spring is released, so that it has been converted into the electrical contact with the second plug-in contact element producing spatial configuration. In this embodiment, the biasing device is formed by at least one clamping hook, which sets the at least one contact spring by deflecting from an abutment position on the second plug contact element in the prestressed state, d. H. in the position that has the contact spring before connecting the plug contact device with the counter-plug contact device in the delivery state. This embodiment is realized in the first variant of the plug connection device according to the invention.

The at least one first plug contact element is preferably formed by a contact device which surrounds the second plug contact element after connecting the plug contact device with the counter plug contact device in the manner of a sleeve. This sleeve may have a plurality of contact springs in the form of contact fingers extending from a sleeve base and aligned substantially axially parallel to each other and spaced from each other connected to the sleeve base to form the required elasticity. The contact springs are preferably connected on one side only with a sleeve base. The sleeve base and the contact springs form in the tensioned state, for example, a substantially cylindrical shell around the second plug contact element, which is spaced therefrom. The distances between the free-hanging ends of the contact springs of the second plug contact element may each be the same size, so that the contact springs together form a sleeve with a circular cross-section.

The biasing device of this embodiment, like the contact springs may be formed of individual clamping hooks, or a plurality of such clamping hooks form a biasing device, which are interconnected. Preferably, as well as the contact springs, the tensioning hooks surround the second plug contact element and are arranged so that they can be brought into engagement with the respective contact springs. For example, each clamping hook can be arranged above a corresponding contact spring. Each contact spring is assigned in this case in each case a clamping hook, which lifts the contact spring from the contact position on the second plug contact element and thereby biases. Thus, the clamping hooks as the contact springs together the second plug contact element in the manner of a sleeve, for example, surrounded by a circular cross section, wherein the individual clamping hooks can in turn be connected to a sleeve base. Alternatively, the biasing device may also be formed by a bush which is offset from the contact springs in the axial direction of the second plug contact element and which has an inwardly tapered portion which engages under the contact springs to lift them from the contact position on the second plug contact element and to be able to stretch or store the contact springs on the second plug contact element.

In a second preferred embodiment according to the first variant, the first plug-in contact element is formed by a retaining sleeve part and a coiled wire spring, and the Biasing device is formed by a clamping bush part. The holding bush part is provided with at least one opening which extends on a circumferential line of the holding bush part. The coiled wire spring surrounds the retaining bush part, is held in the at least one opening and engages through this in the relaxed state at least partially therethrough. The clamping bush part also surrounds the first plug-in contact element, has a groove-shaped recess parallel to the position of the coiled wire spring and is displaceable parallel to its longitudinal axis. The channel-shaped recess is open to the coiled wire spring. In the relaxed state, that is, when the wire spring is not deformed and has a circular cross-section, the wire spring is at least partially on the second plug contact element, because they can access due to their then smaller cross-section through the openings therethrough. This relaxed state is achieved when the channel-shaped recess of the clamping bush part is placed over the wire spring and this space provides for expansion, so that their deformation is reversed in the radial direction. To clamp the wire spring, the clamping bush part is pushed over the wire spring, so that the groove-shaped recess is no longer over this and it is deformed due to the smaller gap between the at least one opening in the retaining sleeve part and the inner wall of the clamping sleeve part in the radial direction. Due to the deformation in the form of a flattening, the wire spring is lifted out of the at least one opening and thus lifted from the contact position on the second plug contact element, so that the wire spring in the tensioned state can not make electrical contact with the second plug contact element.

The holding bush part and the clamping bush part may preferably be cylindrically shaped. In this case, these two parts are preferably arranged coaxially with each other. In the holding part of the socket, an opening or there may be more openings. Since the aperture (s) serve to allow the wire spring to reach through it to make electrical contact with the second plug contact element, these must each be sufficiently long to allow this engagement. A plurality of apertures are preferably aligned with one another in order to allow the wire spring to pass through all apertures. However, the aperture (s) must not interfere with the stability of the retaining sleeve portion so that the pieces of the retaining sleeve portion that are separated from the aperture (s) still need to be securely connected.

Thus, the wire spring can be solved by the contact position on the second plug contact element again by the sliding element is axially displaced, so that the channel-shaped recess is moved away from the wire spring, the openings are preferably equipped with such beveled side walls that caused by the sliding operation on the clamping bush part deformation the wire spring lifts out of the opening (s), these bevelled side walls serving to cause the wire spring to slip on the section change caused by the deformation towards flattening.

In a third preferred embodiment of the connector device according to the invention according to their first variant, the first plug contact element is formed by a twistable contact socket part (hyperbolic contact) having a plurality of hyperbolic deformable and spaced apart slats, and in the relaxed or only partially tensioned twisted state rests on the second plug contact element. In the non-twisted state, the lamellae preferably extend parallel to the axis. In this embodiment, the biasing device is formed by a rotatable actuator which deflects the twistable contact socket part by at least partially canceling the torsion of an abutment position on the second plug contact element and thereby placed in the prestressed state.

In the non-twisted state, the contact socket part has a maximum inner diameter which allows the contact socket part to not bear against the second plug contact element. In the twisted state, the contact socket part (with hyperbolic bending of the slats) is fitted, so that its inner diameter is reduced and the contact socket part comes to rest on the second plug contact element.

Alternatively and according to the second variant of the connector device, both the contact socket part can be twisted in the tensioned state as well as the torsion in the untensioned state be at least partially canceled. In this fourth preferred embodiment of the connector device according to the invention according to the second variant, the first plug contact element is biased in the position in which it comes into contact with the second plug contact element (contact position), and is in the position in which it is not in with the second plug contact element Touch comes, not or only partially biased. The first plug-in contact element is therefore tensioned in this embodiment, when it is twisted and thus transferred to the contact position.

In any case, ie in the case of the third and the fourth embodiment of the connector device according to the invention, it is advantageous if the contact socket part has lamellae which extend between a first and a second socket base and are interconnected by them, so that the contact socket part by a lamella with parallel struts, a top chord and a bottom chord is formed.

Whether the contact socket part is tensioned in the twisted or non-twisted state or not tensioned in the non-twisted state or twisted state depends on the production:
In the first case (stretched in the twisted state), the contact socket part, for example by forming the lamellae substantially perpendicular to a socket base and in the second case (in the non-twisted state tense) by forming the lamellae at an angle <90 ° to the socket base produced. The slats can be made for example by punching out of a metal sheet, which is then bent and rolled to the contact socket part. In this respect and with respect to other features, such as a protective sleeve, which can surround the contact socket part is on DE 100 05 297 A1 The disclosure of which is hereby incorporated by reference in the present application. Thus, the torsion is carried out exclusively in the elastic range, the contact socket part is elastically deformable.

In a fifth preferred embodiment of the connector device according to the invention according to its second variant, this is formed by at least one contact spring which rests in the prestressed state on the second plug contact element, wherein the adjusting device is adapted to the at least one contact spring by deflecting a second plug contact element not touching Position in the prestressed state and thus to put in a second contact contact element contacting position.

For example, the adjusting device may be formed by an adjusting bush having, for example, an inwardly arched bead or an inwardly acting projection, wherein the bead or the projection on the actuating sleeve by axial displacement of the actuating sleeve against a projection on the at least one contact spring starts and this therefore presses against the spring force against the second plug contact element. The adjusting sleeve displaces the at least one contact spring by deflecting from a position not touching the second plug contact element into the prestressed state and thus into a position contacting the second plug contact element. For this purpose, the adjusting bush is moved parallel to the longitudinal direction of the at least one contact spring, so that the bead or the projection on the adjusting bush can press down the at least one contact spring.

As in the case of the first preferred embodiment of the connector device, the at least one first plug contact element is preferably formed by a contact device which surrounds the second plug contact element after connecting the plug contact device with the counter plug contact device in the manner of a sleeve. This sleeve may have a plurality of contact springs in the form of contact fingers extending from a sleeve base and aligned substantially parallel to each other and spaced from each other connected to the sleeve base to form the required elasticity. The contact springs are preferably connected only on one side with a sleeve base. The sleeve base and the contact springs form in the non-tensioned state, for example, a substantially cylindrical shell around the second plug-in contact element, which is spaced therefrom. The distances of the free-hanging ends of the contact springs of the second plug contact element may each be the same size when they are spaced from the second plug contact element, so that the contact springs in this position together form a sleeve with a circular cross-section.

According to the invention, according to a first method step, first a first plug-in contact element 110 a connector device 100 provided. For example, it is a plurality of contact springs 110 , which are arranged sleeve-shaped about a common axis. The connector device, for example, a plug housing 100 be. Furthermore, also a second plug contact element 210 a counter connector device 200 provided ( 1a ). The first plug contact element 110 is in an electrical contacting with the second plug contact element 210 not allowing spatial configuration. The first plug contact element 110 is initially not in this position of the energy storage 115 . 116 applied. This energy storage 115 . 116 For example, spring forces caused by an elastic deformation of the first plug contact element 110 can be caused. In the present position in accordance with 1a is the first plug contact element 110 not biased.

In a second process step ( 1b ) become the connector device 100 and the counter connector device 200 connected with each other. In the present case, the second plug-in contact element 210 and the first plug contact element 110 moved relative to each other without contact, ie inserted into each other / inserted. Even after plugging is still no electrical contact between the first plug contact element 110 and the second plug contact element 210 conditions.

Subsequently, the connector device 100 with the mating connector device 200 mechanically locked / locked. This is not shown separately.

In a further method step according to the invention, after the mechanical locking of the connector device 100 with the mating connector device 200 an electrical contact between the first plug contact element 110 and the second plug contact element 210 produced ( 1c ). To do this, the two energy storage act 115 . 116 on the first plug contact element 110 and press this against the second plug contact element 210 , This force can also be used to connect the connector device 100 from the counter connector device 200 automatically disconnect again if the lock / lock has failed.

In the 2 - 5 are particular embodiments of connector pairs according to the invention, each in a position in which the connector device and the mating connector device are not in electrical contact (a), and in a position in which the connector device and the mating connector device are in electrical contact (b ). The illustrations shown show the elements only in the cross-sectional representation, with rotationally symmetrical elements are shown only over the respective sectional plane. The respectively shown second plug contact element 210 is a plug of a connector receptacle (not shown). The first plug contact element shown in each case 110 is part of a plug-in housing (not shown). In the illustrations, the plug housing and the plug receptacle are already connected to each other, ie inserted into one another, so that the first plug contact element 110 and the second plug contact element 210 each lie opposite each other.

In 2 is a first embodiment of a connector pair with a first plug contact element 110 a connector device, for example a plug-in housing, and a second plug-in contact element 210 a counter-connector device, such as a connector receptacle, shown. The first plug contact element is by a plurality of contact springs 110 formed, only one of which is shown, which are arranged parallel and spaced from each other and together form an elastic contact sleeve, which the plug 210 surrounds. The contact springs 110 are at one end 111 attached (not shown). At the opposite end 112 are the contact springs 110 freely movable unless provided by a pretensioner 120 be held firmly. The contact springs 110 Stand in the position where they are from the plug 210 are lifted, under tension ( 2a ) and are de-energized or at least partially relieved when they attach to the plug 210 come ( 2 B ).

The pretensioner is by tension hooks 120 formed of which in 2 also only one is shown. The biasing device is by a variety of clamping hooks 120 formed in parallel and spaced from each other and each of a contact spring 110 are assigned so that they are the contact springs 110 individually in one of the plug 210 can hold off. The tension hooks 120 together form a clamping sleeve, which the contact springs 110 surrounds. The tension hooks 120 are rigidly held in a holder (not shown) so that they deflect the contact springs 110 do not allow.

According to 2a are the contact springs 110 from the tension hooks 120 from the plug 210 lifted so that no electrical contact between the contact springs 110 and the plug 210 According to 2 B are the contact springs 110 on the plug 210 on, so that an electrical contact is made. For this purpose, the tension hooks 120 the contact springs 110 released, so that they have been deflected under their residual stress against the plug. So the tension hooks 120 the contact springs 110 they must be triggered. Serves for this purpose a triggering device (not shown) which in turn is triggered after locking / locking the connector device with the counter-connector device.

By locking the plug housing with the plug receptacle, the clamping hooks 120 released by means of the triggering device, so that the contact springs 110 against the plug 210 deflect and establish the electrical contact. The triggering device provided for triggering can according to the embodiment of DE 10 2005 040 952 A1 be formed, for example in the form of the fixing element described in this document, which solves the clamping hooks from a fixed position, said fixing is displaced by the insertion process.

An example of a latching connection with a latching edge and a latching hook is in the embodiment of DE 10 2005 040 952 A1 shown for the connection of the local Umgehäuses with an aggregate connection. Such locking elements can also be used for the locking / locking of the connector device shown here with the mating connector device.

In 3 a second embodiment is shown. In this case, the first plug contact element 110 through a coiled wire spring 117 and a retaining sleeve part 118 educated. The holding bush part 118 surrounds the plug 210 , The coiled wire spring 117 lies on the surface of the holding bush part 118 on and around this too The coiled wire spring 117 lies on an opening 119 on. Thus the stability of the holding bush part 118 through the opening 119 is not affected, this does not extend over the entire circumference of the retaining sleeve part 118 but only a part, not just an opening 119 but a plurality of mutually aligned openings 119 may be present (not shown) The holding bushing part 118 is rigid while the coiled wire spring 117 in a direction perpendicular to the spring axis (radial direction) is elastically deformable, so that it is flattened in a deformation and in the undeformed state has a circular cross-section.

Furthermore, a clamping bush part surrounds 130 the holding bush part 118 and the coiled wire spring 117 , The clamping bush part 130 has a groove-shaped recess in the form of a bead 131 on. The clamping bush part 130 is substantially parallel and coaxial with the retaining sleeve part 118 aligned The retaining bush part 118 and the clamping bush part 130 are over their ends 114 . 132 held. The clamping bush part 130 is further displaced relative to the retaining bush part in the longitudinal direction, so that the bead 131 over the coiled wire spring 117 can be placed. If the bead 131 not over the coiled wire spring 117 is placed, is the gap between the retaining sleeve part 118 and the clamping bush part 130 low, so the coiled wire spring 117 is deformed (see 3a ). Due to the deformation, the coiled wire spring 117 flattened and widened, leaving them on the breakthrough 119 rests. Will the bead 131 over the coiled wire spring 117 Placed, this is a larger space available, so that their deformation can be reversed. This reduces their width, allowing them through the opening 119 reach through and with the plug 210 can come into contact (see 3b ).

The first plug contact element 110 is therefore in this embodiment in the position in which it is on the plug 210 not in contact, in a preloaded position (deformed coiled wire spring 117 ), while the first plug contact element 110 in the position where it is at the plug 210 is in the unbiased position.

The clamping bush part 130 is to release the first plug contact element 110 in a direction parallel to the axis of the plug 210 and the holding sleeve part 118 to move. To trigger this shift, the clamping bush part 130 in turn, be moved by a triggering device (not shown) which in turn is released by moving the plug housing and the plug receptacle beyond their latching / latching. The triggering device provided for triggering can according to the embodiment of DE 10 2005 040 952 A1 be formed, such as in the form described in this document Fixing element that releases the clamping bush part from a fixed position, this fixing element is moved by the insertion process.

The locking connection used for locking the connector device shown here with the mating connector device, for example, in turn with a locking edge and a latching hook as in the embodiment of DE 10 2005 040 952 A1 be realized.

In 4 a third and fourth embodiment is shown. In this case, the first plug contact element 110 through a contact socket part 140 formed, consisting of a sheet with spaced apart slats 145 made to a sleeve, the contact socket part 140 shaped (bent and rolled) is. The contact socket part 140 surrounds the plug 210 , The slats 145 are on one side with a first end sleeve base 141 and on the other side with a second end sleeve base 142 in particular integrally connected. In 4 is the sleeve 140 shown cut. The sleeve 140 is in a first position where she is not twisted ( 4a ), in tension and in a second position in which she is tortured ( 4b ), under no tension (third embodiment), or in a first position in which it is not twisted ( 4a ), under no tension and in a second position in which she is tortured ( 4b ), under tension (fourth embodiment). In the non-twisted state, it is the plug 210 spaced and therefore does not produce electrical contact. In the twisted state it lies on the plug 210 and therefore produces an electrical contact. In the twisted position are the slats 145 hyperbolic deflected inward and thus allow electrical contact with the plug 210 ,

The contact socket part 140 is at a first end 143 attached To transfer the first plug-in contact element 110 (in the form of the twistable sleeve 140 ) from the twisted state to the non-twisted state and vice versa is the other end 144 the sleeve 140 to move in rotation. For this purpose, an actuator (not shown), the unilaterally a rotational force in the contact socket part 140 initiates. This actuator can be released or moved by a triggering device as in the cases of the first and second embodiments. For this purpose, the plug housing and the connector receptacle beyond their locking / locking to move out.

The locking connection used for locking the connector device shown here with the mating connector device, for example, in turn with a locking edge and a latching hook as in the embodiment of DE 10 2005 040 952 A1 be realized.

In 5 a fifth embodiment is shown in which the first plug contact element as in the case of the first and second embodiments by a plurality of contact springs 110 is formed, but only one of which is shown, which are arranged parallel and spaced from each other and together form an elastic contact sleeve, which the plug 210 surrounds. The contact springs 110 are at one end 111 attached (not shown). At the opposite end 112 are the contact springs 110 versatile. In this case, the contact springs 110 in the to the plug 210 spaced position under no tension ( 5a ), while in the position in which they plug 210 issue ( 5b ), are under tension.

So that the contact springs 110 contrary to their voltage for contact with the plug 210 arrive, when the plug housing and the plug receptacle are inserted into each other and locked / locked together, is an adjustment in the form of a control sleeve 150 provided that the contact spring 110 surrounds. The adjusting bush 150 has an inwardly arched bead 151 on, against run-up slopes 113 in the contact springs 110 start and the contact springs 110 to the plug 210 deflect out when the actuator bushing 150 is displaced in a direction parallel to the longitudinal axis of the contact sleeve. In order for this movement to come about, it is again possible to use a triggering device (not shown) which is then released and the adjusting bushing 150 can trigger or move when the plug housing and the plug receptacle are locked together / latched and beyond have been moved against each other. The triggering device provided for triggering can according to the embodiment of DE 10 2005 040 952 A1 be formed, for example in the form of the fixing element described in this document, which solves the actuating sleeve from a fixed position and in the direction of the starting slope 113 moves, this fixing element is moved by the insertion process.

In 5a the position is shown in which the contact sleeve, consisting of the contact springs 110 , in the unbiased state and spaced from the plug 210 located. By moving the adjusting bush 150 to the left runs their bead 151 against the chamfers 113 on the contact springs 110 on, so this to the plug 210 to be deflected. As a result, they come to rest on the plug 210 so that an electrical contact is made.

The locking connection used for the locking of the connector device shown here with the mating connector device can For example, again with a locking edge and a latching hook as in the embodiment of DE 10 2005 040 952 A1 be realized
