Description

The invention relates to a connector, in particular a push-pull connector, a plug for such a connector and a connector system.

For separating or connecting two line sections, which are formed for conducting an electrical current and / or transmitting electronic signals, it is known to use connector systems. The individual connectors of these connector systems have connecting portions which can be coupled by means of a positive connection and / or a frictional connection and in particular when used in devices which require securing the connection against unintentional release, such as when used in industrial plants or in a motor vehicle a screw connection are securable. In addition, there are so-called push-pull connector systems in which without the provision of a thread or a nut coupling of the connector system is achieved. The problem is that only one of the various systems can be used only because the conventional connector systems are incompatible with each other.

The object of the present invention is to provide an improved connector, a connector for such a connector and a connector system.

According to one aspect of the invention, there is provided a connector, in particular a push-pull connector, having a receiving area for receiving a connection area of a complementary connector, the connector having at least one lance and one movable relative to the lance Socket element, wherein the sleeve member substantially encloses the receiving area and the lance at least partially, wherein on the lance a latching hook for undercutting a holding configuration of the complementary plug and a displacement configuration is formed, and wherein the sleeve member has at least one lifting configuration and the lifting configuration with the Displacement configuration cooperates, that during a movement of the sleeve member relative to the lance, the lance is elastically displaceable radially outward.

Advantageously, the connector according to the invention for separating or connecting two current-carrying line sections is suitable in devices that require the use of vibration-proof or against unintentional release secured connections during operation of the device due to resulting vibrations and / or frequent relative movements of individual components against each other and yet fast and should be easily solvable.

For making an electrically conductive connection between the connector and the complementary connector plug connector and / or plug may have a connection contact. The plug connector and / or the plug can have an insulation body or a plug insulation body in which the connection contacts can be arranged. The insulation body or connector insulation body can have a plurality of substantially cylindrical insulation body recesses which extend in the axial direction through the insulation body or connector insulation body. In the Isolationskörperausnehmungen the terminal contacts may be arranged, which may each have a Litzenverbindungsabschnitt. The Litzenverbindungsabschnitte can each be connectable to the electrical lines or the individual strands of a respective associated electrically conductive cable. In order to produce such an electrically conductive connection, the strand connection sections are each connected to an associated strand, for example by means of soldering or clamping the strand to the strand connection section. The number of connection contacts of a connector or plug is not limited, and may be, for example, 2 to 8 or more.

The connection contacts furthermore each have a contacting section, wherein the contacting section can be designed as a female or as a male variant. The terminal contacts of the plug are preferably each formed as a male contacting portion, wherein the male contacting portion is formed such that it is insertable into a female contacting portion. The terminal contacts of the connector are preferably each formed as a female contacting portion, wherein the female contacting portion is formed such that it can accommodate a complementary male contacting portion. The female connector may also be referred to as a socket. If a contact is made between the preferably male contacting portions of the plug and the preferably female contacting portions of the connector, the plug and the connector are electrically connected. In other words, for producing an electrically conductive connection or the plug connection, the male contacting sections of the complementary plug are pushed in a plugging direction into the female contacting sections of the plug connector, the plugging direction resulting from a directed movement of plug and plug connector along their axial extent relative to one another.

The receiving region of the connector may in particular be defined by the movable sleeve element and the at least one lance, wherein the sleeve element at least partially surrounds the lance. The sleeve member may be movable relative to the lance in the axial and / or radial direction. Instead of a single lance may also be provided a plurality of lances, which are at least partially enclosed by the sleeve member.

The lance extends with its longitudinal dimension along the longitudinal axis of the sleeve member and has a latching hook which can undercut a holding configuration formed on the complementary plug such that the Connection of connector and plug is positively held in the plug position. The latching hook may extend from the lance at least radially inwardly, in which case the holding configuration of the plug extends radially outwards from the plug, so that the latching hook can undercut the holding configuration. The term undercutting may in principle also be understood to mean engagement behind or behind or hooking. In other words, in this application, the terms "undercut", "behind the back", "rear hook" or "hook" can be used interchangeably.

If a plurality of lances are provided on the plug connector, the plug can have a plurality of holding configurations, in particular one per lance in each case. The latching hook of the lance and / or the holding configuration of the plug can each be formed with a bevel, so that during a plugging movement of the latching hook can slide past the retaining configuration with little resistance. The lance is elastically displaceable in particular during the sliding past the latching hook on the holding configuration and springs back after sliding past, whereby the latching hook can engage in a form-fitting manner behind the holding configuration. Since the lance can be displaced outwards, different outer profiles can be formed on the plug without hindering connection of plug connector and plug.

To release the positive connection between latching hook and holding configuration, the sleeve member may have a lifting configuration per lance, which can cooperate with a formed on each lance displacement configuration such that upon relative movement of the sleeve member to the lance, the lance is radially outwardly displaceable. With the radial displacement is meant a movement of the lance in a radial direction, ie along an imaginary, orthogonal to the longitudinal axis extending through the connector. The term "outwards" refers to the direction of movement of the lance during the elastic displacement with respect to the receiving area in a radial cross section, wherein the receiving area represents an inner area. So the lance shifts into Outward direction, away from the reception area.

For displacement of the lance, the sleeve member can be moved relative to the lance so that the lifting configuration of the sleeve member is arranged approximately congruent to the displacement configuration of the lance, whereby the lance displaces elastically in the radial direction to the outside. In order to avoid tilting of the displacement configuration with the lifting configuration during the relative movement, the displacement configuration and / or the lifting configuration may each have a slope. As a result, the displacement configuration and the lifting configuration slide during a relative movement along the slopes and the relative movement can be carried out with little and approximately constant effort. With decreasing force, the displacement configuration and the lift configuration slide along the slopes from each other such that an original position of the sleeve member, ie the position before the relative movement, is substantially reached again, whereby the lance is no longer elastically deformed.

Once the lance is elastically displaced outwards, the plug is free from the positive connection between the latching hook of the lance and the holding configuration of the plug and the connection region of the plug can be pulled out of the receiving region of the connector, whereby the electrically conductive connection is separable.

At least one limiting section may also be formed on the plug connector, which limits a relative movement of the sleeve element relative to the lance such that during the relative movement the lifting configuration of the sleeve element can not be moved beyond an intended position on or beyond the displacement configuration of the lance.

Depending on the embodiment, the relative movement of the sleeve element can take place either in the axial direction relative to the lance or in a radial rotational movement relative to the lance. The slopes on the displacement configuration of the lance and / or on the lifting configuration of the sleeve member can be provided according to the intended relative movement. The sleeve member is preferably formed substantially cylindrical and extends coaxially with the connector or the insulating body. The sleeve element can be coupled via the lance or the lances to the plug connector or the insulation body, in particular to be coupled exclusively via the lance or the lances to the plug connector or the insulation body.

The sleeve element preferably has a sleeve ring lying radially inward, and the lifting configuration is formed on the sleeve ring.

The sleeve ring of the sleeve member is advantageously inexpensive to produce by means of different manufacturing processes. Thus, for example, the sleeve member may be integrally formed with the sleeve ring by means of an injection molding, or sleeve member and sleeve ring are formed in several pieces, by means of subsequent joining the sleeve member is connected to the sleeve ring, such as by gluing, pressing or welding. The thus formed sleeve member with radially inner sleeve ring moves at a relative movement of the sleeve member to the lance the sleeve ring and thus the lifting configuration, whereby during a relative movement of the sleeve member to the lance, the lifting configuration can engage with the displacement configuration.

Preferably, the sleeve ring has at least one recess, and the lance extends through the recess such that the lifting configuration to the lance is located radially inward, and by means of a relative movement of the sleeve member to the lance the lifting configuration engages the displacement configuration, whereby the lance radially displaceable elastically to the outside.

The recess may be radially outwardly formed on the sleeve ring and be radially outwardly open, whereby the lance is elastically displaceable radially outward. This can ensure a disability-free mobility of the lance become. The sleeve ring may otherwise be connected to the sleeve member at the remaining portions.

If the connector has a plurality of lances, then the number of recesses of the sleeve ring can correspond to the number of lances, wherein in each case one lance can be arranged in a recess. Advantageously, the catch hooks of the plurality of lances can be released simultaneously from the holding configurations of the plug by means of a single relative movement of the sleeve member to the lances, whereby the plug is unlocked by a working step and removable.

Preferably, the sleeve member and the sleeve ring are separate components. The sleeve ring may be disposed in the sleeve member. The sleeve member and the sleeve ring may each be formed as one-piece components. The sleeve member and the sleeve ring can also be designed as a multi-part component. If the sleeve ring is arranged in the sleeve element, a two-part sleeve assembly is formed. In particular casting, milling or injection molding can be used as a method for producing the sleeve member and the sleeve ring.

Preferably, the catch hook and the displacement configuration in the same radial direction. Consequently, the latching hook and the displacement configuration can either face together in the radial direction inwards or in the radial direction outwards.

Preferably, the sleeve member has at least one radially inwardly deformed lance passage portion, the lance passage portion extending in the axial direction along a portion of the sleeve member, and wherein the lance passage portion has a recess and the lance extends through the recess along the radially inwardly deformed lance passage portion in that the lifting configuration for the lance is arranged radially inward, and by means of a relative movement of the lance Sleeve member to the lance, the lifting configuration with the displacement configuration is engaged, whereby the lance is elastically displaceable radially outward.

In other words, the radially inwardly deformed lance passage region of the sleeve element extends in regions in the direction of the longitudinal axis of the sleeve element and has a depth in which the lance can extend from the passage of the lance through the recess along the radially inwardly deformed lance passage region. The lift configuration may be formed on a suitable portion of the lance passage area as a structure extending radially outward from the sleeve member or lance passage area. By suitable portion is meant in particular that portion of the lance passage region which extends in the axial direction, i. in the direction of the longitudinal axis of the sleeve member, located approximately at the height of the displacement configuration of the lance. The displacement configuration may be inward in the radial direction. By means of a relative movement of the sleeve element to the lance, the lifting configuration can engage with the displacement configuration, whereby the lance is elastically displaceable radially outward. Advantageously, the sleeve member can be produced in such a way without the provision of a sleeve ring, wherein the lifting configuration is formed in a cost effective manner by providing the inwardly deformed lance passage region with the recess.

Preferably, the connector has a plurality of lances, wherein the lances are formed on a support member and each of the displacement configurations of the lances so cooperate with the lifting configurations of the sleeve members that upon movement of the sleeve member relative to the plurality of lances, the lances simultaneously radially outward are elastically displaced.

The carrier element may be annular and / or sleeve-shaped and forms the basis for the lance or preferably the plurality of lances. The lances extend from the carrier element axially forward in one Plug-in direction of the connector, which runs opposite to a plug-in direction of the plug.

Advantageously, a plurality of lances can be produced in one piece together with the carrier element, for example as a rotary part or by means of an injection molding method, whereby a cost-effective production and a simple assembly are achieved in the connector. In addition, no additional supports for the plurality of lances are provided on the connector.

Preferably, the lances are spaced apart at regular angular intervals. Advantageously, the receiving area of the connector is formed with a uniform distribution of lances, whereby the electrically conductive connection of the connector with the complementary plug inadequate electrical contact between each other, complementary terminal contacts of connector and plug is avoided. In addition, it is ensured that at a load of the connector system, so the connector and the komlementären plug with a force all lances have to hold about the same amount of force, whereby damage to individual lances, such as breakage or plastic deformation is avoided.

Preferably, the latching hook and the displacement configuration extend radially inwardly from the lance. As a result, with a relative movement of the sleeve element to the lance, the lance can be displaced radially outward elastically, whereby the positive connection between latching hook and holding configuration by means of a step is solvable, the connector has a smooth profile to the outside. The connector thus advantageously has a small footprint.

Preferably, the latching hook and / or the displacement configuration have a sloping section. The lance therefore advantageously slides with little resistance along the lifting configuration of the sleeve element and along the holding configuration of the plug, overcoming the elastic deformation of the plug Lance, whereby a connection of the plug with the connector can be done without much effort.

According to a further aspect of the invention, there is provided a plug for a connector, the plug having a connection portion with a thread and a holding configuration, and wherein the thread has at least one axially extending lowered portion, wherein in a plug-in position of the plug and the connector the lance is arranged in the lowered region such that the holding configuration of the plug is undercut by the latching hook of the at least one lance.

The plug may include a plug insulation body, wherein the plug insulation body may include a plurality of substantially cylindrical insulation body recesses extending in the axial direction through the plug insulation body. In the Isolationskörperausnehmungen terminal contacts may be arranged, each having a Litzenverbindungsabschnitt. The Litzenverbindungsabschnitte can each be connectable to the electrical lines or the individual strands of a respective associated electrically conductive cable. To make such an electrically conductive connection, the strand connecting portions may each be connected to an associated strand, such as by soldering or clamping the strand to the strand bonding portion.

The connection contacts furthermore each have a contacting section, wherein the contacting section can be designed as a female or as a male variant. The terminal contacts of the plug are preferably each formed as a male contacting portion, wherein the male contacting portion is formed such that it is insertable into the preferably female contacting portion of the connector.

The thread of the plug may have a plurality of lowered portions, which may be formed approximately strip-shaped, wherein the lowered portions of the holding configuration starting extend in the insertion direction or in the axial direction. The lowered areas can be made by way of example by milling and can be designed as a flattened residual thread or completely without thread. The lowered areas may also be referred to as thread recesses. The depressed areas may be formed along the circumference of the connection area in the areas corresponding in the plug-in position to the areas of the lances and the lifting configurations of the connector. Preferably, the plug has three lowered areas. The lowered portions may have different widths in the circumferential direction. In this case, a lowered region can be wider in the circumferential direction, while the other lowered regions have a-preferably the same-narrow dimension in the circumferential direction. The wider lowered area may serve as a visual guide that must be aligned with an orientation mark or orientation recess of the connector for proper connection with the connector. Furthermore, one of the lances and / or the lifting configurations of the connector can be made wider in the circumferential direction than the remaining lances or lifting configurations, so that the plug can only be correctly aligned with the connector and inserted into the connector. The plug can be performed with the correct orientation even before reaching the plug position in its plug movement towards the connector through the interaction of the lowered areas with the lances or lifting configurations to the plug position. The lowered area or the lowered areas are flanked in particular in the circumferential direction of threaded portions. Through the threaded portions screwing of the connector with the plug is made possible by means of a fastening nut.

Although the plug for arranging a plurality of lances may have a plurality of lowered portions or threaded portions, the plug is screwed by means of the thread in a conventional complementary screw connector with an internal thread. The plug is thus advantageously both for conventional connectors with an internal thread, as well as for the Connector provided according to one aspect of the present invention.

Preferably, the thread has a plurality of lowered portions, and a depressed portion has a circumferentially wider dimension than the other depressed portions. Due to the differently dimensioned lowered areas, namely a lowered area with a wider dimension in the circumferential direction and the other areas with a narrower dimension in the circumferential direction, in a plug movement of the plug into the connector positioning from plug to connector already from the first contact of Latch hook or lifting configuration to lowered area done.

According to another aspect of the invention, there is provided a connector system comprising a connector and a plug.

In the following, an embodiment of the invention with reference to the accompanying figures will be described in more detail. It is understood that the present invention is not limited to this embodiment, and that individual features of the embodiment can be combined within the scope of the appended claims to form further embodiments.

Fig. 1 shows an exploded perspective view of a connector 10 according to one embodiment, comprising a cable 12 with presently five strands 14 thereof. The cable 12 or strands 14 are formed to carry an electrical current and / or transmit electronic signals. The strands 14 are each connected to a strand connection section of a connection contact AK of an insulation body 16, the insulation element 16 having a plurality of the connection contacts AK. For this purpose, the insulating body 16 has a plurality of substantially cylindrical Isolationskörperausnehmungen extending in the axial direction through the insulating body. In this Isolationskörperausnehmungen each terminal contacts AK are arranged. In the present case, the insulation body 16 has five connection contacts AK, which can be contacted via the end faces 20a, 20b.

The insulating body 16 has a substantially cylindrical shape and is formed of a non-conductive material, in this case made of thermoplastic polyurethane (TPU). The insulating body 16 may also be formed from another suitable plastic. The connection of the individual strands 14 with the respective strand connecting portion is formed in the present case by means of soldering.

An end portion 22 of the cable 12, the strands 14 soldered to the strand connecting portions, and a rear end portion 24 of the insulating body 16 are surrounded by a protective sleeve 26. The protective sleeve 26 is connected to the end portion 22 and the rear end portion 24 by means of encapsulation, which can be in this encapsulation to the last step in the assembly of the connector 10. The protective sleeve 26 is formed of a non-conductive material, in this case made of thermoplastic polyurethane (TPU). The cable 12 and the strands 14 thereof are connected to the non-free end with an electronic component or an electronic device. On the insulating body 16 is between the End face 20a and the end face 20b, a flange 28 is formed. The flange 28 is approximately centrally between the two end faces 20a, 20b, but spaced from the rear end portion 24 and of the protective sleeve 26 (see Fig. 3 ).

The connector 10 further has a carrier element 30, wherein the carrier element 30 is pushed in the axial direction 18 from the end face 20 b onto the insulating body 16. In the present case, the carrier element 30 is formed as a carrier ring 32 with a carrier wall 34 lying radially on the carrier ring 32 (see also FIGS Fig. 4 ). The arrow 36 shows the radial direction, wherein the center of a surface enclosed by the carrier ring 32 in a radial plan view represents the innermost point.

The carrier ring 32 has a tailor-made to the rear end portion 24, centrally disposed opening and is connected to a flanged ring 28 facing end side by means of a joining process, in this case compression, with an end face of the flange 28, wherein it is at the end face of the flange 28 is that , which in turn faces the carrier ring 32.

In the present case, a plurality of lances 38 are formed on the support wall 34 of the carrier element 30, more precisely, three lances 38 are provided. The carrier element 30 is produced in one piece as a turned part.

The lances 38 extend from the support wall 34 axially in the insertion direction of the connector SR _SV and are arranged on the support ring 32 radially outboard, whereby the lances are spaced by the radial width of the support ring 32 of the insulating body 16. The lances 38 are also spaced from each other on the support ring 32 by the same angular distance, in this case 120 degrees. The support member 30 is made of a metal such as brass or a spring steel.

The lances 38 are elastically displaceable radially outwards and each have a latching hook 40 and a displacement configuration 42. The latching hook 40 and the displacement configuration 42, on the other hand, are stiff and substantially non-elastically deformable. The latching hook 40 and the displacement configuration 42 extend radially inwardly from the lance 38 and each have a ramp-like shape with a slope S.

The latching hook 40 is formed for undercutting an associated holding configuration 44, also comprising a bevel S, of a complementary plug 46 (see FIG Fig. 7 and 8th ), whereby in a plug-in position of the complementary plug 46 with the connector 10, the connector system comprising the plug 46 and the connector 10, in the present case is positively connected. To form the plug-in position plug 46 and connector 10 are pushed together in the axial direction 18, wherein each of the bevels S of the latching hook 40 and the holding configuration 44 can slide on each other, whereby the lance 38 is elastically displaceable radially outwardly. As soon as the latching hook 40 has passed the slope S of the holding configuration 44, the lance 38 moves back to the original position and the latching hook 40 engages behind the holding configuration 44.

In the present case, the carrier element 30 is surrounded by a sleeve element 48, the sleeve element 48 essentially being formed as a hollow cylinder whose longitudinal extent is arranged along the axial direction 18. The sleeve member 48 thus also surrounds the region of the insulating body 16 which is surrounded by the carrier element 30. The sleeve member is made by means of a die-casting process of zinc and has sections of a circumferential corrugation R on which the sleeve member 48 is non-slip tangible. The corrugation R can be formed from a rubber element arranged on the sleeve element 48. The corrugation R further has an orientation recess, which allows a positionally accurate placement of the plug on the connector.

At the sleeve member 48 is radially inwardly lying and substantially terminal a sleeve ring 50 is formed (also win Fig. 6 and 8th ). The sleeve member 48 and the sleeve ring 50 form a sleeve assembly 64 (see Fig. 6 ). The sleeve ring 50 is produced as a separate component, ie as an independent component by means of an injection molding process from a Kunsstoff or by machining from a metal and pressed by means of press fitting with the hollow cylinder.

The sleeve ring 50 herein has three lift configurations 52, one lift configuration 52 per lance 38. The lift configuration 52 is formed as a recessed portion of the sleeve ring 50 and can each engage the shift configuration 42 of an associated lance 38. For this purpose, the sleeve ring 50 is formed in the region of the lifting configuration 52 with a recess 54 in which the lance 38 is arranged with a lance intermediate portion L arranged between the latching hook 40 and the displacement configuration 42, whereby the lifting configuration 52 to the lance 38 is arranged radially inward.

The sleeve member 48 and the sleeve ring 50 formed thereon are movable in the axial direction 18 relative to the lance 38, so that by means of a relative movement of the sleeve member 48 and the sleeve assembly 64 to the lance 38 in the insertion direction of the plug SR _S, the lifting configuration 52 with the displacement configuration 42 in Intervention occurs, whereby the lance 38 is displaced radially outwardly elastic. In order to allow unimpeded relative movement of the sleeve member 48 to the lance 38 in the direction of the end face 20b, a distance A is provided between the protective sleeve 26 and the flange ring 28 and the support ring 32 arranged on the flange ring 28 (see FIG Fig. 3 ). Alternatively, the sleeve member 48 may be embodied with a shape that may surround the protective sleeve 26, so that no distance A must be provided.

The engagement between the lift configuration 52 and the shift configuration 42 is such that due to the axial relative movement of the sleeve member 48 and the sleeve assembly 64 to the lance 38, the lift configuration 52 slides along the slope S of the shift configuration 42 and thereby radially outwardly directs the lance 38 relocated. In order not to hinder the displacement of the lance 38, the sleeve element in the insertion direction SR _{SV is} radial formed in widening

In a relative movement of the sleeve member 48 and the sleeve assembly 64 to the lance 38 in the insertion direction SR _SV , the lifting configuration 52 slides along the displacement configuration 42 back to the original position, namely to the position at which the lance intermediate portion L between the latching hook 40 and the displacement configuration 42 is, whereby the lance 38 is no longer displaced. Since in the present embodiment, the support member 30 is formed with three lances 38 and the sleeve ring 50 has three recesses 54 and three Hebekonfigurationen 52, ie one per lance 38 are by means of the relative movement of the sleeve member 48 and the sleeve assembly 64 to the lance 38th in the direction of the end face 20b all three lances 38 at the same time elastically displaceable radially outward. As a result, a rear hooking of the retaining configurations 44 of the complementary plug 46 can be released by the latching hook 40 of the lance 38, as a result of which the plug 46 can be separated from the plug connector 10. In the present embodiment, the connector is formed as a female part of the connector system, ie, the connector has the female terminal contacts AK, which are formed for receiving the male terminal contacts of the plug 46. Alternatively, the connector 10 may also be designed as a male part of the connector system. Furthermore, a molded seal 56 is arranged on a region of the flange ring 28, which ensures a flush connection between the plug 46 and the connector 10.

Fig. 2 shows in a perspective view of the assembled state of the connector 10. On the end face 20a of the insulating body 16, the terminal contacts AK are arranged, which are formed for receiving the current-carrying terminal contacts of the plug 46.

Fig. 3 shows a side view of the connector 10, from which the arrangement of the sleeve member 48 in relation to the protective sleeve 26 can be seen with a distance A. The sleeve member 48 is for unlocking a connection of the plug 46 and connector 10 (not shown here) in the direction of the protective sleeve 26 displaceable by the distance A, whereby the lances 38 enclosed by the sleeve member 48 can move radially outwardly elastically, so that a rear hook of the holding configuration 44 of the plug 46 by the latching hooks 40 in the plug position is solvable. The corrugation R serves for a comfortable and slip-proof gripping of the protective sleeve.

Fig. 4 shows in detail the support member 30 on the support wall 34, the lances 38 are formed. The latching hooks 40 and the displacement configurations 42 are formed at the end portion in the insertion direction SR _{SV of} the lances 38 (see FIG Fig. 1 ). Between the latching hooks 40 and the displacement configurations 42, the lancet intermediate section L is located at which the lifting configuration 52 and the recess 54 of the sleeve ring 50 are arranged.

The latching hooks 40 and the displacement configurations 42 each have the slope S, wherein the slope S of the latching hooks do not have to run with the same angle to the lance 38 as the slope S of the displacement configurations 42. The respective slopes of different embodiments may be different.

Fig. 5 shows the support member 30 with sleeve ring 50 arranged thereon, wherein the sleeve ring 50 is arranged with the lifting configuration 52 in the region of the lance intermediate portion L. The lances 38 are in a non-displaced state. If the sleeve ring 50 is displaced by means of a movement of the sleeve member 48 in the insertion direction SR _S (see Fig. 1 ), the lifting configurations 52 each press on the slope S of the displacement configurations 42 (see FIG Fig. 4 Hidden here by the lifting configuration 52), whereby the lances 38 are increasingly displaced elastically radially outward. As the lift configuration 52 slides along the slopes S back to the lance intercepts L, the lances shift back to their original position.

Fig. 6 shows a perspective view of the sleeve assembly 64, wherein in the In this embodiment, the sleeve assembly 64 includes the sleeve member 48 and the sleeve ring 50. The sleeve ring 50 has at its lifting configurations 52 each have a recess 54, whereby the lifting configuration 52 is spaced from the hollow cylindrical body of the sleeve member 48 that between the sleeve member 48 and the lifting configuration 52, the lance 38 can be arranged. The number of recesses 54 in this case corresponds to the number of lances 38, namely three.

Fig. 7 shows a perspective view of a plug 46. The plug 46 is presently formed as a male connector, ie the plug 46 is formed with its male connection contacts for insertion into the female terminal contacts AK of the connector 10, and has a cable (not shown) with present five Line contacts or strands (not shown) thereof. The cable or strands are formed to carry an electrical current and / or transmit electronic signals. The strands are each connected to a terminal contact (not shown) of a plug insulation body (not shown). The plug insulation body has a substantially cylindrical shape and is formed of a nonconductive material, in the present case of thermoplastic polyurethane (TPU). The connection of the individual strands to the respective line contact region is presently formed by means of soldering.

The plug 46 has a radially outer thread 58, wherein the thread 58 has a plurality of axially extending lowered portions 60, wherein at the plug-in direction of the connector 10 rear portions of the depressed areas 60 also a holding configuration 44 is formed. In the plug-in position of plug 46 and connector 10, the lances 38 extend along the lowered portions 60 to the holding configuration 44 and undercut the holding configuration 44 with the latching hooks 40. In this case, a lowered portion 60 is provided on the plug 46 for each lance 38 , The lowered portions 60 can be made by milling the thread 58.

The holding configuration 44 has a slope S on which the bevel S of the latching hook 40 can slide along, whereby the lance 38 is displaced radially outwardly elastically until the latching hook 40 engages behind the holding configuration 44 and undercuts the holding configuration 44. For connecting plug 46 to the connector 10, it is therefore not necessary in this embodiment, the lances 38 by means of the sleeve member 48 to displace radially outwardly elastic.

Fig. 8 shows the connector system comprising the plug 46 and the connector 10 in a disconnected state, wherein the arrow 62 shows the insertion direction in which the plug 46 can be pushed into the connector for establishing an electrically conductive connection.
