Description

The invention is directed to an electrical connector in Preamble of claim 1 specified type. This connector consists of two connecting parts, which are moved with the help of a laterally movable Slider can be axially coupled or uncoupled. The slide relieved the axial joining or loosening of the two connecting parts. Of the Slider is guided in the housing of a connecting part via control means and has a profiled coupling channel in which one of the housing the other connecting part laterally projecting coupling pin in one first position of the slide can be axially inserted or executed. There is then an extended release position of the slide the housing of the connector receiving it. The slider but can also be moved into another position by the control means, where the coupling pin of wall parts located in the coupling channel is overlapped axially. There is then a locking position of the slide where the coupling position of the two connecting parts is secured.

In the known connector of this type, the control means exist between the slide and the housing receiving it in that the slide is designed as a carriage, which is transverse to the coupling axis extending rails in the housing is guided to move. Of the The coupling channel provided in the slide has an angled course and the axial height of this angular course determines the axial stroke, with which the two connecting parts during the transverse movement of the slide be pulled into each other in the case of coupling. To the coupling process to guide the housings of the two connecting parts deeply into one another and the electrical contacts and mating contacts located there are optimal to engage, the greatest possible axial lifting height is required. However, in order to obtain a large axial lifting height, the known one had to Connector the distance between the channel entrance and the channel end of the angled coupling channel in the slide is appropriately large be. This requires a large overall height of the slide and him receiving housing.

If you look at the known connector by moving the slide a large axial stroke when coupling or uncoupling the two connecting parts wants to get, the rise from the angled coupling channel the slider should not be too steep, otherwise it will be a difficult one Operation of the slide results. For a flat angle the coupling channel, on the other hand, there is a large transverse displacement distance of the slide in the housing. Therefore the slider protrudes in its extended release position correspondingly far out of the housing. Then a correspondingly large side is to operate the slide Space next to the connecting part receiving it is required. This There is space, especially when using the plug connections in the motor vehicle area, not always available, which is why you rely on connectors with a small axial stroke.

With a different type of electrical connector (EP-0 501 502 A2) it is known for the coupling or decoupling process instead a laterally extendable slide one on the housing of a connecting part to use rotatably mounted washer, which two to their rotating pin has diametrically opposed, S-shaped channels. Of the an S-shaped channel serves as a coupling channel for the coupling pin of the other connecting part, while the second S-shaped channel as Control channel with a located on the housing of the first connecting part Control pin interacts. Through the second control channel and the control pin the turntable with its rotating pin is in an axial Housing groove moves. The diameter of the turntable is additive determines the axial height of the two diametrical channels. Hence it results there is a relatively large overall height of the turntable and the rotary bearing Housing. In addition, the handling of the turntable is difficult, because their inner surface is always on the outside of the housing abuts, while its outer surface has a diametrical rib for its rotary actuation having. The diametrical rib can only be in the cone area of the Turntable can be gripped by hand, making only a relative small rotational force can be exerted. A small actuating force can only correspondingly low coupling forces between the two connecting parts exercise. In addition, the turntable cannot be turned sideways extended release position can be brought with respect to the housing and consequently cannot, like a slider, with great thrust be retracted into the housing.

In another detachable connector of a different type (DE-41 29 236 A1) it is known to have a locking lever fixed on the connector housing to store a connecting part and a projection on the socket housing to be provided when coupling the two connecting parts manually through an axial opening in a transverse coupling channel of the Retractable socket housing. When swiveling the locking lever the projection moves into the clutch channel and presses over its fixed one Pivot bearing place the connector housing axially into the socket housing. In the coupling position, the two connecting parts are against axial Moved out secured. The rotation of the locking lever is proportional large and is a quarter circle around it - with respect to the two Connecting parts - from a radial position before coupling into one to transfer axial position after coupling. This requires great Space in the vicinity of the connecting parts. A large axial stroke between the two connecting parts require a large distance between the Projection of the pivot point of the locking lever and one accordingly great length of the cross slot. This adversely affects large dimensions of the two housings of this connector.

In a known plug connection (DE 42 28 531 A1) it is known to store a slider on the socket housing and fix it with a Link guide for a coupling pin provided on the connector housing equip. The same coupling pin engages in an axial coupling channel of the socket housing. The slide is U-shaped and has a tongue-shaped latching position for the slide, which by a cutout is formed in the U-bracket leg of the slide. The slider has a locking element on at least one of the two bracket legs for resting. Even with this plug-in connection, only one Small axial stroke when coupling or uncoupling the two connecting parts to reach.

The invention has for its object an inexpensive connector to develop the type mentioned in the preamble of claim 1, the both with regard to the two housings of the connecting parts and also with regard to the lateral movement of the slide relative to the one receiving it Housing has small dimensions and still a large one provides axial stroke of the connecting parts when coupling or uncoupling and is easy to operate. This is done according to the invention achieved the measures listed in claim 1, which have the following special meaning.

When moving in the socket housing, the slide performs a translatory Swivel movement in the socket housing, for which he has two different Owns control means. The first control means is an axial control with a linear axial groove on the socket housing and a radial bearing cam on the slide, which is a translational movement to each other execute, but at the same time a translationally movable at their point of contact Create swivel bearing point for the slide. This pivot point serves the other control means, which forms a tilt control and to which on the one hand a backdrop stone and on the other a backdrop tour belong. This guide has a curvature, which the combined swivel-translational movement corresponds. That’s it possible to move the slide in a laterally extended release position to pivot the socket housing where the coupling pin in the open end of the coupling channel of the slide in or out can be. In this release position, extended to the side, the Slide a good contact surface for its manual operation. Here the slide performs a translatory swivel movement and takes when coupling or uncoupling the connector housing through the engagement of the coupling pin in the coupling channel on the slide side.

The coupling channel of the slide is designed as an arc segment, which advantageously determined only by the pivoting movement of the slide is. For a high axial stroke when coupling or uncoupling between a swiveling of the slide is sufficient for the two connecting parts at a relatively small angle, e.g. B. smaller than an eighth circle can be trained. A small swivel angle ensures that the slide in its swung-out release position is proportionate little protrudes from the socket housing, which one accordingly needs to have a small overall width. But also the axial length of the Socket housing can be made relatively small because of the coupling channel formed arc segment itself with respect to the mentioned pivot bearing of the slide is on the same side of the lever as its tilt control. The slide therefore has the relatively small axial dimension of a one-armed lever, the lever arm length of which is determined by the distance between its swivel bearing on the bearing cam on the one hand and the open one End of the arcuate coupling channel is determined on the other hand. Of the slide control part of the tilt control is in between. Thereby the socket housing only needs a relatively small axial dimension to show, which is the lever arm length of the slide minus the translatory movement of its pivot bearing results. Through this Arrangement of the clutch and control means result when the slide is actuated also favorable power ratios according to the lever law. Yet becomes a large axial stroke when coupling and uncoupling the two connecting parts reached because the arc height of the coupling channel for this only needs to deliver a partial stroke, while the remaining stroke from the translational movement the slide in the socket housing is concerned. Because the clutch channel only a partial stroke of the axial one in its arc segment Coupling movement needs to be considered, it has a relative low slope, which results in a smooth guidance of the coupling pin affects. The swiveling slide forms together with the one engaging in the arc segment of the slide via its coupling pin Plug housing an assembly, which when swiveling the Slider moved together translationally.

When installing the slide in the socket housing, an assembly force is used spent the essential, e.g. B. 30%, later on for actuation of the slide required actuating force.

The two connecting parts 10, 20 of the plug connection shown in the figures consist in the illustrated embodiment of a relay 10 and a relay carrier 20, to which a slide 30 according to FIGS. 4 to 6 heard. The slider 30 is used by the arrow 40 in FIG. 7 illustrated coupling movement between the relay 10 and the Relay carrier 20 or by the corresponding counter arrow 40 'in Fig. 10 illustrated decoupling movement.

The relay carrier 20 has a socket housing 21, which is a core piece 23 with numerous axial chambers 24 recognizable from FIGS. 1 and 2. The axial chambers serve to accommodate electrical contacts that locked there and locked captively by a so-called comb 19 are. In Fig. 2 is a dash-dotted position 19 'of the comb 19 illustrates where the crimped onto the conductors of electrical lines 25 Contact parts 22 can be inserted into the axial chambers 24 before, in the extended final click position of FIGS. 1 and 2 of the comb 19 can be locked there. As best seen from the front view of Fig. 2 can be seen where the two end faces lying in one plane the outer casing of the socket housing 21 and the core 23 are highlighted by hatching, the socket housing has a here ring-shaped receptacle 26, in which both housing parts of the relay 10 and parts of the slide 30 are introduced.

The relay 10 has a corresponding to the receptacle 26 of the socket housing 21 designed connector housing 11, which is sleeve-shaped and has a plurality of electrical mating contacts 12 inside the sleeve. The mating contacts 12 are of course in an arrangement pattern in the connector housing 11 positioned, which, as Fig. 3 shows the location of the mentioned Contacts 22 in the socket housing 21 corresponds. The connector housing 11 has one on two diametrically opposite outer surfaces Coupling pin 41 for the coupling or uncoupling movement already mentioned 40, 40 '. Corresponds to the position of the coupling pin 41 the socket housing 21 has an axial insertion opening shown in FIGS. 1 and 2 43 for the coupling pin 41 at its front end. The associated on the other hand, two coupling channels 42 are located in the slide 30, the following Has structure.

The slider 30 is designed as a U-shaped bracket, which to his still to be described in more detail first one in the best 6 shows a vertex web 31, at the web ends thereof at right angles two substantially flat bracket legs 32 sit. The two coupling channels 42 mentioned are each on the mutually facing inner surfaces 33 of the two bracket legs 32 are arranged. Is located at the inner end of the two stirrup legs 32 a bearing cam 51 of an axial control to be described in more detail 50. The bearing cam 51 also projects from the inner leg surface 33 4 from. On the two outer surfaces 34 of the stirrup legs 32 on the other hand, there is a backdrop guide 62 of a still to be described Tilt control 60.

The slide 30 is through a lateral inlet opening, which can be seen in FIG. 1 27 in the receptacle of the socket housing 21 in the sense of Fig. 5 visible insertion arrows 13 inserted until finally, over an increasing ramp, the described bearing cam 51 in a substantially linear axial groove 52 of the socket housing 21 snaps. in the Inside the receptacle 26, the socket housing 21 still has a stationary Sliding block 61, which during this insertion 13 into the associated one Mouth of the slide guide 62 located in the slider 30 retracts. This finally leads to the starting position shown in FIG. 7 of the slider 30 in the socket housing 21. This starting position of the slider 30 can be described in more detail with reference to FIG. 8 Rest position 70 set.

In this starting position, the clutch channel 42 is the best 6 clear channel opening 44 with the one already described Insertion opening 43 aligned in the housing 21. Therefore, on Plug housing 11 located coupling pin 41 there axially in his Fig. 7 apparent starting position in the sense of the insertion arrow 14 introduced become. In Fig. 7 is a dot-dash line also an axially higher position 41 "of the coupling pin illustrates from which the connector housing 11 is inserted axially at the end into the receptacle 26. Because of the free axially inserting the coupling pin 41 into the channel opening 44 or the corresponding pull-out movement counter to the insertion 14, this initial position of the slide 30 is subsequently briefly referred to as "Release position" are referred to.

Starting from the release position shown in Fig. 7, the slide can 30 in a special way with respect to the housing 21 translationally pivoting movement, whereby the slide ultimately into that shown in FIG. 10 other end position 30 'can be transferred, which follows from for obvious reasons, briefly referred to as "locking position" should. This locking position 30 'is also shown in dotted lines in FIG. 7. The combined movement of the slide between the two positions 30, 30 'of FIG. 7 exposes itself, as is indicated there by arrows a pivoting movement 35 and an axial translation movement 55 together.

The coupling channel 42 expediently only takes into account that movement component caused by the pivoting movement 35 and is therefore designed as an essentially circular arc segment 42. In some applications, however, there could already be an axial one Movement component are added. In contrast, the backdrop guide 62 according to the combined sequence of movements from the pivoting movement 35 on the one hand and the translation movement 55, on the other hand, are curved. As already mentioned, the link guide 62 is in the slide 30 arranged, while the associated sliding block 61 stationary in the recording 26 of the socket housing 21 is arranged. But it would also be possible these two elements 61, 62 of the tilt control 60 in reverse to be arranged between the slide 30 and the socket housing 21.

Around the slide 30 from a release position of FIG. 7 into the locking position To transfer 30 'from FIG. 10, one in FIG. 7 indicated by the arrow 15 thrust 15 on the apex 31 of the slide 30 exercised. This apex web 31 therefore moves as can be seen from the intermediate position shown in FIG. 9 the socket housing 21. The slides on the connector housing 11 located coupling pin 21 into the interior of the coupling channel 42 and together with the slide 30 forms a jointly movable Assembly 16. Between the peripheral surfaces of the connector housing 11 and it comes to the inner surfaces of the receptacle 26 in the socket housing 21 an axial guide.

However, this assembly 16 is due to the tilt control 60 described positively guided. The tilt control 60 not only allows the one mentioned in FIG. 7 Pivotal movement 35, which has been partially realized in Fig. 9, but also forces assembly 16 to have a corresponding amount of translational movement 55 on. How to recognize a comparison between FIGS. 7 and 9 can, the bearing cam 51 in Fig. 9 axially in its groove 52 after moved down. The coupling movement 40 between the two housings 11, 21 is therefore not only from the circular curvature of the coupling channel 42 came about, but also by the 60 in the tilt control certain axial component. The slide 30 has tilted somewhat its bearing cam 51 being in contact with the axial groove 52 the relevant pivot bearing 53 for the pivoting movement described above 35 forms. This pivot bearing point 52 moves axially in the groove 42. It is important that the tilt control 60 with respect this pivot bearing 51 is on the same side as the clutch channel 42 with the coupling pin 41 engaging in it. Both Elements 41, 42 and 60 lie on the same lever arm 36, which is shown in FIG. 9 is indicated. The tilt control 60 is closer to that of the Touching the bearing cam 51 in the axial groove 52 determined pivot bearing 53 arranged as the clutch channel 52.

In the locked position of Fig. 10, the slide is with its apex 31 pressed on the socket housing 21 laterally and thus the Effect of the thrust 15 ended. The coupling pin 41 is located itself at the inner, closed end of the coupling channel 42 and is therefore axially covered by the channel wall of the clutch channel 42. There is one Locking the relay 10 in the relay carrier 20 before. Even the backdrop stone 61 has reached the end of its guide 62 and has the bearing cam 51 guided into its axially lowest position in the groove 52. The two housings 11, 21 are brought into their axial, full coupling position in FIG. 10, whereby their contacts 22 and counter contacts 12 explained in FIG. 1 are in maximum engagement.

Despite the relatively low overall height of the slide, due to its cams 10 illustrated lever arm 36 is illustrated, and despite of only a small pivot angle 37, which can be seen in FIG 35 °, is a large one, indicated by arrow 45 in FIG. 7 Axial stroke 45 came about when coupling 40. This axial stroke 45 is composed of two components 46, 47. The pure swivel movement 35 leaves an axial partial stroke 46 between the coupling pin 41st arise, which by the axial arc height of the coupling channel 42nd is determined in the slider 30. If you leave the translation movement 55 initially disregarded, the coupling pin 41 would move the distance of this partial stroke 46 in Fig. 7.

As shown in dotted lines in FIG. 7, it arrives in the locked position 10 of the coupling pin in the dotted in Fig. 7 illustrated End position 41 ', which determines the entire axial stroke 45. This lower clutch position 41 'results because of the positive guidance the tilt control 60 still takes the aforementioned translational movement 55, those shown in Fig. 7 by the dashed or dotted Bearing cam 51 or 51 'is clarified. Through this translational movement there is a residual stroke 47 which is additive to the aforementioned partial stroke 46. A larger axial stroke 45 is achieved than through the small one Swivel angle 37 and the arc shape of the coupling channel 42 to be expected is. The arc of the coupling channel 42 is relatively flat and the center of curvature is far more distant than that through the pivot bearing 53 certain length of the lever arm 36 in the slide 30 corresponds. This results in a smooth retraction of the coupling pin 41 in the coupling channel 42.

4, 6 and 8 includes the already mentioned latching position 70 two locking projections 71, 72, which can best be seen in FIG. 5 radially resilient tongue 38 sit. Form these locking projections 71, 72 thus resilient locking elements. An essentially rigid counter-rib 73 of FIG. 8 is of a housing wall in this exemplary embodiment 28 of the socket housing 21 is formed. The resilient tongue 38 is created through a U-shaped cutout 39 in the respective stirrup leg 32. The two locking projections 71, 72 are located, as shown in FIGS. 4 and 6 show, on the inner surface 33 of the respective leg 32. They rise 8, while towards the outer surface 34 there is a free space 54 recognizable from FIG. 8.

5 already described in connection with FIG Slider 30 in the socket housing 21, it is recommended to the inner locking projection 71 to provide an inclined ramp 79. When assembling 13 then the pre-rib 71 is pushed away from the edge of the housing wall 28, by the tongue 38 in the direction of arrow 49 of FIG. 8 in the free space 54 springs into it. The inner surface of the drawing broken away in FIG. 7 and the side wall 29 of the socket housing shown in FIG to guide the slide 30 on the outer surface 34 of its stirrup leg 32. The side wall 29 delimits the above-described free space 54 behind the resilient tongue 38.

7 and 8, the counter-locking rib 73 engages between the two locking projections 71, 72 and thereby determined the aforementioned release position of the slide 30 in the socket housing 21. This counter-latching rib 73 is most easily created by one according to FIG. 8 slightly undercut wall edge of the mentioned housing wall 28, which the entry opening already mentioned above, from FIG. 1, in the lower picture 27 of the socket housing 21 limited in the receptacle 26. According to FIG. 12, the undercut 56 is on both surface sides the housing wall 28 is formed. The angle 59 of this undercut is at 5 °. The associated locking projections 71, 72 result in this complementary undercut flanks 75, 76.

The inner locking projection 71 has an axially increasing run-up slope 74 provided with a nose 17 provided on the connector housing 11 can work together. This can be seen from Fig. 3. If you practice with above-described insertion movement 14 of the connector housing 11 a slight axial force, the nose 17 moves onto the ramp 74 and presses the tongue 38 in the direction of the arrows 49 shown in FIG. 8 resiliently into the mentioned free space 54. The tongue 38 is bent away. This position 38 'of the tongue is illustrated in Fig. 12. Thereby also becomes the outer locking projection 72 with respect to the counter locking rib 73 pivoted away on the housing wall 28 and releases the detent 70. Now the slide 30 in the sense of the mentioned thrust 15 in 9 can be tilted further. This is the actuation 15 of the slide 30 for the clutch movement 40 facilitated, though in this case there is a positive locking position according to FIG. 8. This measure of inactivating the latching position 70 comes independent inventive meaning.

Alternatively, the latching position could also be seen in FIG. 13 Have structure. 13 shows the effective latching position shown in FIG. 8 of the slider 30 shown. The flanks 75 ', 76' on both sides of the two locking projections 71 ', 72' ensure a non-positive locking the wall edge 73 '. In this case, the undercuts described above do not apply 56. There is a non-positive locking position 70 '. Also the previously described ineffectiveness of this latching position 70 'by means of the the nose 17 belonging to the plug housing 11 can be omitted.

When the slide 30 moves further in the sense of the thrust 15 the final position shown in FIG. 10 is finally reached, namely the locking position described. This locking position too can be secured by a rest position. For this purpose, the slide has at least on the inner surface 33 of one of its stirrup legs 32 Fig. 6 visible locking rib 77, which also with the wall edge 73 of the housing wall 28 cooperates in the area of the lateral inlet opening 27. Between the locking rib 77 and the crown 31 of the slide 30 remains a distance 64, in which the housing wall 28 during the transition snaps into their locking position shown in FIG. 10. It is coming to a temporary deformation in the area of the locking rib 77. 10 shows, is thus also the locking position shown in Fig. 10 of the slide 10 against the socket housing 21 secured.

In the further course of the coupling movement caused by the tilting slide 30 40 runs over the nose 17 of the connector housing 11 the inner Locking projection 71 and finally arrives at the one shown in FIG. 10 lower end position inside the socket housing 21. During the disconnection process 40 'of FIG. 10 there is initially a deformation in the area the locking rib 77 when the slide, in the opposite direction to the aforementioned Thrust 15 is actuated by means of a pulling force 15 '. over the intermediate position of FIG. 9 finally occurs via the intermediate position 9 to the pre-locking position of FIGS. 7 and 8. The outer locking projection 72, namely, as can be seen from FIG. 8, has an oblique Ramp 78, which lies opposite the undercut flank 71 described above. The slide 30 is thereby visible in FIG. 8 Release position locked. This applies mutatis mutandis to the described alternative embodiment of the latching position 70 'of Fig. 13, where the outer Locking projection 72 'has a corresponding inclined ramp 78'.

As illustrated in FIG. 3, the connector housing 11 is in the peripheral area provided with code ribs 18, 48, 21 code grooves in the socket housing 57 and 58 are assigned in the receptacle 26 of the socket housing 21. As a result, an assignment of defined relays 10 to associated relay carriers is provided 20 guaranteed and an erroneous swapping excluded. This is from the coupling position of the two connecting parts 10, 20 in 11 can be seen.

To differentiate between different variants of relays 10 and relay carriers 20 To be able to, the code ribs 18, 48 in different, in Fig. 3 alternative positions 18 'and 48' shown in dash-dotted lines be. The associated code grooves 57, 58 are then in the associated socket housing 21 placed accordingly. This coding also ensures that the connector housing 11 only in a certain rotational orientation in the socket housing 21 in the sense of the insertion arrow 14 of FIG. 7 is insertable and the lugs 17 can perform their prescribed function.

Claims (12)

1. Electrical plug-in connection consisting of two releasable connecting portions (10, 20), in particular a relay and a relay support for motor vehicles, which can be axially coupled to each other (40) or uncoupled (40') by means of a laterally extendable slider (30) as well as locked in their coupling position relative to each other,

   wherein one connecting portion (20) comprises a socket housing (21) with electrical contacts (22) mounted therein and the socket housing (21) has a lateral receptacle (26) with control means for the slider (30),

   while the other connecting portion (10) comprises a complementary plug housing (11) axially guided in the socket housing (21) during coupling (40) or uncoupling (40'), with electrical counter contacts (12) mounted therein and with at least one laterally projecting coupling pin (41) for the coupling movement controlled by the slider (30),

   and the slider (30) has a profiled coupling channel (42) for the coupling pin (41) of the plug housing (11) and is movable by the control means in the socket housing (21) between two positions (30, 30'), namely

   on the one hand a laterally extended release position (30) in which the plug housing (11) can be axially introduced or removed (14) by its coupling pin (41) in the open end (44) of the coupling channel (42) of the slider (30)

   and on the other hand a retracted locking position (30') in which the plug housing (11) is located in the socket housing (21) in the fully coupled position, the contacts (21) are electrically connected to the counter contacts (11) and the coupling pin (41) is axially overlapped by the coupling channel (42),

   characterised

   in that between the slider (30) and the socket housing (21) are arranged two different control means (50; 60) which define a translational (55) pivot movement (35) of the slider (30) in the socket housing (21),

   wherein the first control means forms an axial control device (50) with an essentially linear axial groove (52) on the socket housing (21) and a radial bearing projection (51) on the slider (30) which in addition to its translational movement (55) in the axial groove (52) also defines the pivot bearing point (53) for the pivot movement (35) of the slider (30),

   and the second control means forms a tilt control device (60) with control portions constructed on the one hand as a connecting link block (61) and on the other hand as a connecting link guide (62), wherein the connecting link guide (62) is curved according to the combined pivot and translational movement (35, 55) of the slider (30),

   and in that the coupling channel (42) is an arcuate segment which essentially only defines the lever-like pivot movement (35) of the slider (30) and which is arranged relative to the pivot bearing point (53) of the slider on the same lever arm side (36) as its tilt control device (60) and whose axial arcuate height of course defines only a partial stroke (46) of the coupling or uncoupling movement (40, 40') between the plug housing (11) and the socket housing (21),

   but the plug housing (11) by its coupling pin (41) engaging in the arcuate segment (42), together with the slider, forms a unit (16) which is translationally movable in the socket housing and which delivers the axial residual stroke (47) for the coupling or uncoupling movement (40, 40').
2. Plug-in connection according to claim 1, characterised in that the slider (30) is of U-shaped construction and the apical web (31) of its U serves for slider actuation (15)

   and the two U-arms (32) at their inner faces (33) have both two mutually opposed arcuate coupling channels (42) for two coupling pins (41) located on opposite side faces of the plug housing (11) and two bearing projections (51) of the axial control device (50),

   while on the outer faces (34) of the two U-arms (32) are arranged one set of control portions (62) of two mutually opposed tilt control devices (60), while their two other control portions (61) are located on the socket housing (21) (Figs. 4 to 6).
3. Plug-in connection according to claim 1 or 2, characterised in that the connecting link block (61) of the tilt control device (60) is arranged stationarily in the socket housing (21), while the associated connecting link guide (62) is located on the slider (30).
4. Plug-in connection according to any of claims 1 to 3, characterised in that on the slider (30) the control portions (62) belonging to the tilt control device (60) are arranged closer to the bearing projection (51) of the axial control device (50) defining the pivot bearing point (53) than the arcuate coupling channel (42) in the slider (30), which serves to receive the coupling pin (41) of the plug housing (40) (Fig. 6).
5. Plug-in connection according to any of claims 1 to 4, characterised in that the release position of the slider (30) in the socket housing (21) is fixed by a latch holding means (70).
6. Plug-in connection according to claim 5, characterised in that two latch projections (71, 72) of the latch holding means (70) are seated on a radially resilient tongue (38) of the slider (30) and form resiliently yielding latch elements,
   while an essentially rigid counter latch rib (73) which in the release position moves between the two latch projections (71, 72) is located on the socket housing (21).
7. Plug-in connection according to claim 6, characterised in that the spring tongue (38) is produced by a cut-out (39) in the arm (32) of the U-shaped slider (30).
8. Plug-in connection according to claim 6 or 7, characterised in that the two latch projections (71, 72) of the latch holding means (70) are arranged on the inner face (33) of the two U-arms (32) of the slider (30).
9. Plug-in connection according to any of claims 6 to 8, characterised in that the two arms (32) of the U-shaped slider (30) on their outer face (34) comprise a free space (54) for the tongue (38), into which the tongue (38) springs during the latch transition.
10. Plug-in connection according to any of claims 6 to 9, characterised in that the counter latch rib (73) is produced by the wall edge of the housing wall (28) of the socket housing (21) which defines the entrance opening (27) of the receptacle (26) for the slider (30).
11. Plug-in connection according to any of claims 6 to 10, characterised in that the inner latch projection (71) on the tongue (38) has an axial approach ramp (74) for a lug (17) located on the plug housing (11)

    and the lug (17) during the axial coupling movement (40) of the plug housing (11) slides over the approach ramp (74) and pushes the tongue (38) radially away

    until the outer latch projection (72) releases the counter latch rib (73) located on the socket housing (21) (Figs. 3, 8).
12. Plug-in connection according to any of claims 2 to 11, characterised in that the U-shaped slider (30) comprises a latch element (77) on at least one of its two U-arms (32), which in the locking position (30') of the slider cooperates with the counter latch rib (73) which in the release position (30) of the slider forms part of the latch holding means (70).
