Description

Electrical angle-shaped connector with a first angle leg and with a second angle leg

The invention relates to an electrical angle-shaped connector, in particular with an electrical contacts having insulating body, which is arranged in the use position in a first angle leg of this connector, said emanating from the insulating body and the electrical contacts line or lines through a second angle leg to a consumer or to a Current source, wherein the two aneinander¬ lying in the angular range end faces of this angle leg obliquely and substantially mitred and - especially in the region of an outer meridian - at least in use position articulated or releasably connected to each other and wherein also a the use position of the two angle legs fixing bracket is provided.

Such an angular connector is known from DE 200 03 976.8 U1 and has proven itself. For mutual fixing of the two angle legs in the use position flanges or flange pieces are provided on both angle legs, each passing through them together

Screw can be attached to each other and to a housing wall or the like. This results in a determination of the two angle legs to each other, however, a greater effort is required for this mutual determination of the position of use when closing the two relatively pivotable angle leg. Especially the screwing is time consuming, especially when multiple screws must be set. Although in DE 34 03 772 C2 and DE 37 09 963 CI each have an angular cable entry _f no insulator with electrical contacts, known in which the two angle legs are locked together, the

Locking devices must be attached to the angle legs themselves. The mutual connection is therefore no longer possible if, for example, one of the catches is damaged or breaks off due to material fatigue or overstressing.

There is therefore the object to provide an angle-shaped plug connector of the type defined, in which the assembly and in particular the acquisition of the use position take less time and the risk that the mutual connection of the angle leg is unusable, is reduced.

In order to achieve this object, the angle-shaped connector defined at the outset is characterized in that at least one of the two angle legs is provided with a recess or annular groove extending over the greater part of its circumference and open outwards over at least part of its course a spring ring fitting into it can be inserted or latched in, that this spring ring is open or interrupted in its course and at the opening or interruption has two end portions, of which at least one in use position over the recess or annular groove and protrudes from the angle leg and closing - or use position of the connector, the holder detected at the other angle leg, is connected thereto or engages. In this way, eich vcrcchlucc füi for the wmi eJ-shaped connector, in which no time-consuming screwing must be performed to set the two angle legs in their position of use. Rather, a snap-lock spring ring is present, which can engage due to its running over more than half of the circumference of an angle leg shape of this angle leg and then detected with at least one or both end portions of the holder on the other angle leg, so that both angle leg thereby in particular releasably are connected. Thus, the danger is reduced or eliminated that serving for mutual connection, with the angle leg itself integrally connected locking parts are damaged or even break and thereby weaken the mutual connection or make impossible.

Especially good is the mutual connection of the first and the second angle leg with each other when the two ins¬ particular symmetrically formed end portions of the spring ring in the position of use detect the holder on the other angle leg or engage therein or are connected thereto. The two end parts, which emanate from the interruption or opening of the ring, so both can be used to connect to the other angle leg, which improves the mutual connection. Since the spring ring is open, so has an interrupted course, it can also be good for latching to him carrying angle leg bent something against its restoring force, then spring back in the use position and over more than half the circumference of this angle leg of this or in the recess or annular groove abut.

Thus the spring ring over more than 180 ° along the circumference of a Exne arbitrary cross-sectional contour having WinkelschenkeIs run and this can include latching, the two arranged on both sides of the interruption of the spring ring end portions in the use position a smaller distance. have one another, as it corresponds to the largest cross section of the WinkelSchenkels or the diameter of the spring ring and the two end portions can be bent outwards relative to the spring ring course and in particular be arranged in the plane spanned by the spring ring level. The spring ring may thus have approximately the shape of a "C", but the two free ends carry outwardly projecting end portions, which detect the second angle leg and the existing there bracket in the closed position of the connector.

The opposite to the annular groove of the one angle leg and ge¬ compared to the spring ring in the direction of the other angle leg projecting end portions of the spring ring may have a distance to each other, in which a conical expansion body of the holder under widening at least these end portions or their distance can be pressed on the other angle leg is arranged and under the conical expansion body for the end portions has a distinction, wherein the conical expansion body is about mushroom-shaped or has an approximately mushroom-shaped longitudinal section and engages in the use position with the expansion body the spring ring end portions.

In this way, a quick release for the mutual connection of the two angle legs are formed, since the two angle legs must be pivoted or folded only in their position of use, whereby the holder with its spreader at the end portions of the spring ring, which is already locked with one angle leg , can engage by the spreader, the two end portions initially opposite Pαickstellkraft auseinanüeröewegt, biε under the spreader body located in the region of the end parts is so that they can then spring back into the closer position and thus set the spreader behind them. The dimensions are coordinated so that this mutual determination is achieved when the two angle legs touch with their facing surfaces in the closed position.

In such an embodiment of the invention, it is therefore sufficient to mount the spring ring in its position of use latching on the one angle leg, after which the two angle legs only folded together to close the connector and thereby must be locked to the end portions of the spring ring. This is much less time consuming than the fitting and tightening of usually several screws and moreover the risk that one of the mutual latching parts is damaged or broken, significantly reduced. If the spring ring is damaged or overloaded with its end parts, it can be easily replaced without the entire connector is unusable.

The end portions of the spring ring may at least partially extend approximately parallel to each other or lying on parallel lines sections or points and their distance may be greater than the smallest dimension of the spreader of the holder but smaller than its largest dimension, what the starting position of these end parts or their location in the closed position. Thus, the spreader can enter the space between the two end portions, when the two angle legs are folded to each other, and can then due to its wedge shape or its conical training the push apart the two end parts against their spring crotch, until the spreader moves through the gap between the two end parts and thus the two angle legs are folded into their position of use. Thereafter, the end parts spring back by themselves into the ange¬ approached position back and thus determine the position of use of the two angle legs.

In this case, the area of the holder located beneath the conical expansion body can have a dimension or width which corresponds approximately to the spacing of the two end parts of the spring ring or is slightly smaller or possibly slightly larger. If this dimension is equal to or less than the distance between the two end parts of the spring ring, they can practically spring back to their starting position. If, however, the dimension or width of this area of the holder is slightly larger than the distance of the two end parts in their relaxed position, they are also in the closed position with some spring pressure at this area of the holder.

The end portions of the spring ring may be straight, wavy or curved in its parallel course, in particular in opposite directions to each other. As a result, the latching can possibly be promoted and at the same time the end parts can be reinforced by such profiling against unwanted permanent deformation.

A modified embodiment of the connector according to the invention can provide that the detent spring or the spring ring receiving recess or annular groove after the - free end of the associated angle leg is limited by a separately attachable holding or flange part and that the detent spring or the spring ring before attaching the separate retaining or ¹ flange part a: _ial on the associated angle leg and the then still open recess or groove is attachable and that after attaching the detent spring or the spring ring, the recess or annular groove limiting part is attached to the angle leg. Thus, if the angular groove having the annular groove and the detent spring has a separate retaining or flange part, optionally a rotatable intermediate piece, which permits a rotation of the angle leg and thus of the entire connector - this can be exploited to form a boundary of the annular groove, so that the Spring ring may not be widened for insertion into its annular groove, but can be plugged in the axial direction before the subsequently attachable boundary of the annular groove is provided.

The recess or annular groove may have a Ver¬ enlargement or broadening as a recess in its course, which can be dimensioned so large that the spring ring located in the recess or annular groove by means of a tool can be detected. In this case, the widening of the recess may extend to one or both sides of the recess or annular groove. Thus, the user can attach a tool to the spring ring in the region of this spread and move the spring ring partially out of the annular groove, which leads to its spreading in the region of its interruption or opening. In this way, so the two end portions can be spread so that they release the cross-spreading or holding body and the connector can be opened.

It is expedient if the broadening of the annular groove of the opening or interruption of the spring ring approximately on a diameter or the cross-sectional center of the angle leg opposite is arranged. Wiröl partially moved out of its annular groove with a tool of the spring ring transversely sui central axis of the angle leg and thereby spread in the region of its opening or interruption, this movement is distributed accordingly equally to both end parts.

The cross section of the spring ring forming part or wire may be at least partially circular and / or polygonal, in particular rectangular. Above all, a cross-sectionally rectangular spring ring can fill a corresponding annular groove well and form a largely smooth course on the outside of the angle leg. It is advantageous if the cross section of the spring ring forming part or wire over its entire course is constant.

In particular, the spring ring can fit in the recess or annular groove, so they practically fill, and be flush with its outer edge or its outer dimension with the edge of the recess or annular groove or recessed against the groove edge. This can avoid that the spring ring protrudes from the outline of the angle leg and possibly unauthorized or unintentionally solved.

A development which is expedient for the stability of the entire angled plug-in connector can consist in that the holder provided in particular with the expansion body has a groove or similar recess which is open towards the angle leg on which the spring ring is arranged, and in that this Spring ring having angle leg has a matching into the groove or recess locking projection. Thereby, the mutual connection of the two angle legs is stabilized in the transverse direction, so that forces exerted on the exposed angle leg in Any direction can be well introduced into the other winkclcchenkel and its attachment to a counterpart or a housing wall.

An easy-to-use arrangement provides that the two end portions of the spring ring are independent of each other and can be easily spread apart from each other accordingly. However, it may be appropriate that the end portions of the spring ring are connected to each other, in particular integrally connected and optionally the spring ring together with the end portions against a restoring force elastically over the cross section of the receiving angle leg is expandable. Such a spring ring can then be so far expanded so that it can be pushed axially over the not yet mounted angle leg until it has reached the annular groove, in which he then can be latched in the same way as an open at the end parts angle leg. The interconnected end portions can then still project relative to this angle leg in an approximately radial direction and cooperate with an expansion body and a holding part on the other angle leg in the manner already described. Also, such a spring ring also closed at the end parts can be expanded and expanded as far as possible by partial withdrawal from the annular groove in the region of the end parts, so that the expansion element of the holder is released again in order to be able to pivot the angle legs apart.

In all embodiments, it is favorable if the recess or annular groove is arranged in a plane perpendicular to the central axis of the angle leg and if the end parts of this spring ring protrude at right angles to the course of this angle leg, in particular eccentrically to the center thereof. As a result, they correspond particularly well a holder and its length at oinern win]: lig angle or right angle ^' to the angle leg having the Federrinq arranged other angle leg.

The recess or annular groove may be provided on the housing wall or a counterpart closer, in particular obliquely or at right angles thereto arranged angle leg and the holder for the or the end part can be located at the angle leg opposite this pivotable or detachable angle leg. The detent spring is then provided on the after attachment to the housing wall or a counterpart no longer movable angle leg, so that the pivoting of the other angle leg in its position of use causes the holder located thereon can be pressed between the end portions of the spring ring and locked it ,

But it is also possible that the recess or annular groove on the one housing wall or a counterpart farther, in particular approximately parallel arranged angle leg vorge is seen and that the holder for the or the end portion of the pivotable this angle leg in use position fixed to the housing wall or a counterpart installed angle leg is located. To close the connector, the angle leg is then pivoted together with the annular spring and its end parts, whereby they are then moved over the fixed support and its expansion body, wherein a spreading takes place, which ends with the locking already described.

In all embodiments, it is expedient if the holder on the angle leg carrying it in an area forming the inside of the angle in the position of use is arranged and in particular a crerinci '? Width has, as e, c corresponds to the largest cross-sectional width or the diameter of the angle bar! S. The holder is characterized practically invisible from the outside and especially for unkown and unauthorized persons thus opening of such a connector is difficult.

It is advantageous if the holder and the position of use thus detected or engaging end portions of the spring ring in the position of use below which they are in their width or cross-sectional dimension superior Win¬ kelschenkeln arranged in the angular space of the angled connector and shielded from the angle legs to the outside. As a result, the holder and the locking of the angle arms are protected and are not readily accessible for unauthorized opening or even destruction.

The cross section of the angle legs can be circular or elliptical or square or rectangular, wherein these different cross-sectional shapes can also be provided differently on the two angle legs. The course of the spring ring is adapted to the cross-sectional shape of him carrying angle leg.

The connected to a housing wall or a counterpart angle leg may have a coaxial, a pivot bearing for the angle leg and the connector adapter and be connected thereto and this adapter can in particular for a connector with a fixed angle leg arranged on the annular groove or recess for the spring ring limit the recess to one side. Thus, such an adapter can have a dual function by one hand, the annular groove for the spring ring or the Rinςrieder limited and on the other hand allows the connector relative to a housing wall or a counterpart about the central axis of the immediately adjacent angle leg can be rotated.

It should be mentioned that in the contact region of the two angle legs, a sealing ring or O-ring can be arranged, which bears sealingly against both facing contact surfaces of the angle legs within the coupling region. In this case, the sealing ring or O-ring can be arranged in the use position in the radial direction deeper than the recess or annular groove, in particular in one of the mutual coupling or connecting serving recess or annular groove adjacent annular groove or the like may be arranged. It can therefore be accommodated despite the annular groove for the annular spring or the spring ring for mutual connection of the two angle legs at the contact area and a seal.

Especially when combining one or more of the above-described features and measures results in an electrical angle-shaped connector whose two relatively movable or pivotable angle leg can be ver¬ tied together by a quick release in its position of use. At the same time, at least on one of the angle legs so that integrally connected locking element, which could be damaged or break off, avoided and replaced by an easily replaceable ring spring or a spring ring, can serve on the protruding end portions as locking elements.

Thus, the spring ring is not too easily from the receiving him annular groove can be pulled across the course of the angle leg, it is advantageous if the annular groove and the spring ring over about three quarters or more _f, for example, extends over about four fifths or about nineteenths of the circumference of the associated angle leg. Due to such a large wrap angle, the spring ring or the annular spring is held securely in its position of use, but can still be plugged and latched well transversely to the longitudinal center axis of the associated angle leg due to their elastic property, if an axial plugging - for example, on a first half still open ring groove - not possible.

Hereinafter, exemplary embodiments of the invention are described in more detail with reference to the drawing. It shows in partly schematized representation:

A generally designated 1 electrical angle connector includes within a first angle leg 2 a non-illustrated and unrecognizable, electrical contacts having insulating body, the outgoing of this insulator and the electrical contacts in a known manner outgoing line or lines by a second angle leg 3 a consumer and / or to a power source. The second angle leg 3 is attached to a housing wall 4 or a comparable counterpart, for example, to a pipe connection, in the use position.

The two aneinander¬ lying in the angular position in functional position end faces 2a and 3a of this angle leg 2 and 3 are obliquely and substantially mitred, as is particularly clear in Fig. 1 and 3, but also in Figs. 2, 4 and 5 detects.

Approximately in the area of an outermost meridian line are the two Wmkelschenkel 2 and 3 gelenlciy and possibly releasably connected to each other, wherein the first angle leg 2 in the exemplary embodiment has a radially projecting flat or flange piece 5 as part of a joint joint 6, while at the second WinkelSchenkel 3 two an intermediate space between free flange pieces 7 are provided , between which the first flange piece 5 can engage, wherein the flange pieces 5 and 7 are connected by a transverse pin 8 rotatable or pivotable with each other.

But it would also be conceivable any other joint shape. For example, the individual flange piece 5 could also be provided on the second angle leg 3, while the flange pieces 7 engaging on both sides in the position of use could be arranged on the first angle leg 2.

In a manner to be described is also a the use position of the two angle legs 2 and 3 fest¬ Legende, designated as a whole with 9 bracket provided, the use position in Figs. 2 and 4 is shown and provides that the two end faces 2a and 3a in their greatest mutual approach or touch each other.

In all embodiments, it can be seen that on one of the two angle legs, in the embodiment of FIGS. 1 and 2 on the first angle leg 2, in the embodiment of FIGS. 3 and 4 on the second angle leg 3, one over the greater part of the circumference of this angle leg extending, practically over its entire course outwardly open recess or annular groove 10 is provided, in which a spring ring 11 matching in it can be inserted or latched, wherein in FIGS. 6 to 8 different embodiments of such Spring washers I 1 cbj are placed. In FIGS. 1 to 5, the respective spring ring 11 is already inserted or engaged in the recess or annular groove 10.

This spring ring 11 is interrupted in all embodiments, even in those according to FIGS. 7 and 8 in the sense open be¬ relationship, in its course, that the ring-shape ends before its completion to a closed ring. It can be clearly seen, in particular in FIGS. 6 to 8, that the spring ring 11 has an opening or interruption 12 with respect to its annular course, on which two end parts 13 depart from the course of the spring ring 11 and outwards, that is to say over the contour of the spring ring Protrude spring ring 11.

The end portions 13 are shown in FIGS. 1 to 5 accordingly also over the recess or annular groove 10 and are from the respective angle leg 2 or 3, so that in the closed or use position of the connector 1, the holder 9 on the other angle leg or 2 and are associated with or intervene in a manner to be described. Above all, a latching with the holder 9 is provided in a manner to be described.

In this case, illustrate all the figures that the two end portions 13 of the spring ring 11 are arranged symmetrically to each other and capture in the use position, the holder 9 at the other angle leg together. For this purpose, the two end portions 13 of the respective spring ring 11 in a relaxed position according to Figures 6 to 8 and in the position of use according to Figures 1 to 5, a smaller distance from each other than the largest cross section of the respective angle leg 2 or 3 or the diameter of the spring ring 11th corresponds and at the same time these end portions 13 are opposite to the Fec'erringverlauf bent in the region of the opening 12 to the outside and arranged in the plane spanned by the spring ring 11 level. The bends 14, via which the end portions 13 are connected to the actual spring ring 11, are practically at the opening 12 or limit this opening 12, as can be clearly seen in Figures 6 to 8.

In this case, the end portions 13 have a distance from each other, in which a conical or wedge-shaped spreader 15 of the holder 9 by widening at least these end portions 13 or their

Distance can be pressed, which is arranged on the other angle leg and under the wedge-shaped or conical

Spreader 15 for the end portions 13 an undercut 16th

(Fig. 1 and 3), said spreader 15 is approximately mushroom-shaped or has an approximately mushroom-shaped longitudinal section and in the position of use with the spreader 15 and the underside located on its underside 16, the spring ring end portions 13 overlaps.

When comparing Figures 1 and 2 or 3 and 4 it is clear that the holder 9 passes with its mushroom-shaped expansion body 15 when closing the respective angle leg 2 in the region of the end portions 13, so that they can be pushed apart by the expansion body 15 until the undercut 16 reaches the region of the end parts 13. In this position

(FIGS. 2 and 4), the end parts 13 can spring back into the relaxed or largely relaxed position due to their spring force and then engage under the spreader 15 on the

Undercut 16, so hold the angle leg 2 in the closed position.

In the exemplary embodiment, the end portions 13 of the spring ring 11 extend in a relaxed position approximately parallel to each other. You could but also lying only on parallel lines' have sections or points, wherein it is important in all cases that their distance is greater than the smallest dimension of the wedge-shaped expansion body 15 of the holder 9, but smaller than its largest dimension. Thus, the spreader 15 can first enter with its smaller dimension between the end portions 13 and then press them apart or spread apart due to its increasing dimension in the folding of the angle leg until the undercut 16 is in the region of the end portions 13. In this case, according to Figure 1, the spring ring with the end portions 13 relative to the fixed bracket 9 and its spreader 15 or according to Figures 3 and 4, conversely, the bracket 9 are moved to the spreader 15 relative to the fixed end portions 13 to the mutual, above-described latching to achieve.

The located below the conical expansion body 15 in the region of the undercut area 17 of the holder 9 has a dimension or width which corresponds approximately to the clear or inner spacing of the two end portions 13 of the spring ring 11 so that they in the position of use according to Figure 2 or 4 practically have their starting position again. Optionally, however, this dimension or width of the region 17 could also be slightly larger, so that then the end portions 13 would rest under spring tension.

According to Figure 7 and 8, the end portions 13 of the spring ring 11 in its parallel course also curved, in particular be curved in opposite directions, so that only a portion extends parallel.

The detent spring or the spring ring 11 receiving recess or annular groove 10 is in the embodiment of FIG 3 to the 5th after the free end of the sugehöiicren WinkelschenJels 3 back, which end is connected in the use position, however, on the housing wall 4, limited by a separately attachable holding or flange 18, so that the detent spring or the spring ring 11 before attaching this separate holding or flange 18 axially on the associated angle leg and then to the side still open recess or annular groove 10 can be plugged. After this axial attachment of the detent spring or the spring ring 11 can then the recess or annular groove 10 to the side limiting part 18 on the

Angle leg 3 are attached to complete the annular groove 10 also after this page and set the spring ring 11 accordingly.

In a frontally on both sides limited annular groove 10, however, a spring ring according to Figure 6 by widening its opening 12 approximately in the plane in which the annular groove 10 is plugged until it practically wraps around the annular groove 10 and is then locked in the use position ,

In an analogous manner, the spring ring according to Figure 6 but also removed again or at least so far withdrawn that the end portions 13 are spread apart, because by retraction of the spring ring 11 of the groove bottom to a corresponding opposing expansion of the detent spring or

Spring ring 11 leads, as indicated in Figure 5. In this way it can be achieved by spreading the end parts 13 that they leave the undercut 16, so that then the angle leg 2 can be opened again. The same applies to an arrangement according to FIGS. 1 and 2.

To make this possible and to facilitate, the recess or annular groove 10 has a magnification or in its course Broadening 19 as a recess that is dimensioned so large that the spring ring 11 located in the recess or annular groove 10 can be detected by means of a tool 20, as indicated in Figure 5. There, a screwdriver is indicated, with which the spring ring 11 can be engaged behind in the region of the widening 19 and then withdrawn to effect the already mentioned spread of the end portions 13.

The widening 19 of the recess may extend to one side. However, they could extend to both sides of the recess or annular groove 10 to capture the spring ring 11, for example, with a pair of pliers.

Furthermore, it would be conceivable that the spring ring 11 itself has a holding or barrel projection on which a tool could attack in order to withdraw it from the position of use something or completely.

The broadening 19 of the annular groove 10 is arranged in the embodiment of the opening 12 or interruption of the spring ring 11 approximately on a diameter or in the cross-sectional center of the angle leg 2 or 3, so that distributed by means of an auxiliary tool 20 retraction forces distributed evenly on both end portions 13 and the end parts 13 are moved approximately evenly apart.

In the figures 6 to 8 is indicated that the cross section of the spring ring 11 forming part or wire may be at least partially circular and / or in particular rectangular.

Figure 6 and 7 shows spring rings 11 with a circular cross-section, while Figure 8 shows an embodiment with a square or rectangular Ouerschni tL of the spring ring 11 forming material.

In this case, this cross section of the spring ring 11 forming part or wire over its entire course is constant. In this case, the spring ring 11 fits into the recess or annular groove 10 and is flush with its outer edge or its outer dimension with the edge of the annular groove or recessed against the groove edge, so that no protrusion on the corresponding angle leg 2 or 3 is formed by the spring ring 11. Particularly well, while the annular groove 10 are filled when a spring ring is used with a rectangular cross-section of it forming wire or part and the cross-sectional shape of the spring ring is adapted to the annular groove 10.

According to Figure 1, the holder 9 has a groove 21 or the like recess which is open to the angle leg, on which in the respective embodiment of the spring ring 11 is arranged. Accordingly, a corresponding groove on the holder 9 is also provided in the embodiment of Figure 3, which, however, from the perspective, in the figure 3 is not recognizable. The spring ring 11 having other angle leg has a matching in this groove or recess 21 locking projection 22 so that in the closed position of the two angles and lateral forces can be transferred well. This locking projection 22 can be seen both in FIG. 1 and in FIG. 3.

In the figures 7 and 8, a special feature is shown to the effect that the end portions 13 of the spring ring 11 are connected together and indeed in one piece, so that the resulting structure despite the opening 12 a total of a closed Course has. In this case, xst this spring ring 11 together with the end portions 13 against a restoring force elastically over the cross section of the receiving angle leg out expandable, so after appropriate expansion in the axial direction of the respective angle leg pushed until then the spring ring 11 is incident and snaps into the annular groove 10 and survive the interconnected end portions 13 in the manner already described. These interconnected end portions 13 can then cooperate in the manner already described with a spreader 15 of the holder 9 are moved apart by this spreader 15 and elastic pass into the undercut 16 behind the respective spreader 15, wherein the spreader 15 and the undercut 16 expediently a 13 may have adapted contour to the course and the connection of the connected end parts. For example, the expansion body 15 in this case, contrary to the rectangular shape of the illustrated embodiments have a round contour.

Conveniently, the recess or annular groove 10 is arranged in all embodiments in a plane perpendicular to the respective central axis of the angle leg extending them and the end portions 13 of this spring ring 11 are perpendicular to the course of this angle leg eccentric to the center of him from, as well can recognize in Figure 1 and 3. This leads to a favorable shape and arrangement of the annular groove 10 and also of the spring ring 11 with respect to an arrangement in which the annular groove 10 and the plane spanned by it would be arranged obliquely to the central axis.

In the embodiments, the cross section of the angle legs 2 and 3 is circular. However, it could also be elliptical or square or rectangular, wherein one angle leg could, for example, have a circular and the other a rectangular or square cross section. In all cases, the course of the spring ring 11 is adapted to the cross-sectional shape of the angle leg, wherein the spring ring 11 grasp the respective angle leg extent and must include that the latching and positive retention described is achieved.

The connected with a housing wall 4 or a counterpart in the use position angle leg 3 has in the embodiment according to Figures 3 to 5 a coaxial, a rotary bearing for the angle leg and the connector 1 adapter containing, which has already been mentioned as a holding and flange 18. Through the connection with this adapter 18 so the entire connector 1 is rotatable relative to the housing wall 4, that is, the direction of the angle leg can be changed. As already mentioned, this adapter or flange part 18, in the case that the recess or annular groove 10 is disposed on this fixed angle leg 3, this recess for the Limit spring ring to one side. Ec would also be conceivable to provide such an adapter 18 in the embodiment of Figure 1 and 2, wherein the spring ring 11 is disposed in an annular groove 10 on the angle leg 2.

In a manner not shown in the contact region of the two angle legs 2 and 3, a sealing ring or O-ring can be arranged, which can bear sealingly against the two facing contact surfaces 2a and 3a within the coupling region. In this case, this sealing ring or O-ring can be arranged in the use position in the radial direction deeper than the recess or annular groove 10 in an annular groove or the like.

It should be noted that the annular groove 10 and arranged in it in the use position spring ring 11 extends over about three quarters or more, for example about four fifths or about nine tenths of the circumference of the associated angle leg 2 or 3, wherein the annular groove for simplicity even over the entire circumference can run. A correspondingly large loop with a correspondingly large latching force of the spring ring 11 is obtained in this way.

The electrical angle-shaped connector 1 with two relatively movable, in particular pivotable or hinged angle legs 2 and 3 can be held in its closed or use position characterized in that at one of the two angle legs extending over the greater part of its circumference, outwardly open recess or annular groove 10 is provided, in which a matching spring ring 11 is arranged, said spring ring 11 is open or interrupted in its course and at the opening 12 or interruption has two end portions 13, opposite to the Projecting Hing history outwardly un>^"!
