  SOCKET CONNECTOR, FOR CABLE

  The invention relates to a plug-in connector for cables with several conductors, for example for mounting on a machine, comprising: contact-pieces of substantially cylindrical shape 5 provided with pins or contact sockets and received in a support sleeve ; a coupling sleeve movable in rotation, for axial locking; and at least one profiled retainer for exit from

axial or angled cable.

  The usual connectors belonging to this type, with axial cable outlet, are in principle constructed differently than the usual connectors with outlet

angled cable.

  On the basis of this, the object of the invention is to improve a connector of the type mentioned at the start, so that the use of a relatively limited assortment of components makes it possible to meet, during manufacture and assembly, the need to have in practice different variants, in particular with regard to the cable outlet, axial or square, this benefiting from manufacturing costs and

reduced mounting.

  According to the invention, this object is achieved by the fact that there is provided a coupling element and 25 shaped retaining pieces usable selectively for an axial or angled cable outlet, these profiled retaining pieces axially stopping the sleeve. coupling capable of turning and capable of being locked on identical cylindrical connection portions by an axial movement of connection with coupling elements of the coupling element, which is capable of being coupled, by its

  other end, to the contact piece.

  The result of such a design is that the basic assortment necessary to make a plug-in connector with axial or angled cable outlet according to the customer's wishes need only include two different profiled retaining pieces which can be plugged onto the connector coupling element. The invention provides that the shell-shaped coupling element, provided with means for absorbing the mechanical tensions of the cable, has locking tabs which are arranged diametrically, axially directed, elastically deformable in the radial direction and capable of be inserted into the locking holes of the connection portion of the profiled retaining part, and that the coupling element is provided with a retaining profile from the rear which can be mechanically coupled with a corresponding profile of the coupling part, by a relative radial movement

  stopped by the coupling sleeve.

  In this case, if the profile of the contact piece with the contact pins is identical to the profile of the contact piece with the contact sleeves, and if the profile of the coupling piece, applied by a shoulder d a radial collar 25 profiled against an annular shoulder of the coupling element, takes the retaining profile from the rear of the coupling element, this by parallel spouts belonging to the profiled collar, the mounting is then particularly simple since the locking sleeve axially stopped by the profiled retaining part put in place stops the radial movement of uncoupling of the coupling element and

of the support sleeve.

  The aforementioned arrangement is a prerequisite for changing the spatial arrangement of the contact carrier parts as required, so that the pins coming into contact with the contact sockets (female contacts) are turned to the right or to the left according to each specific need. 5 We can thus take into account that the current will be brought to the connectors sometimes by the right sometimes by the left. A particularly simple assembly is thus obtained, free of play. It is then expedient that a locking connection by means of a bayonet type junction can be established between the coupling sleeve and the support sleeve, and that '' there is, in a locking groove of the support sleeve, a clamping ramp which, during a rotary movement 15 for locking, forces the support sleeve to move axially towards the coupling sleeve, this by deforming an O-ring, and a locking relief

  to create a stop at the locked position.

  The invention further provides that the rotational movement of the coupling sleeve is limited to a center angle, corresponding to the bayonet type junction, by means of angular stops cooperating with stop edges of the element d coupling, said coupling sleeve being in axial abutment, with the possibility of sliding, this by an annular shoulder, against a corresponding annular shoulder

of the coupling element.

  A particularly simple locking connection, between a partition and the support sleeve, can be obtained if, as shown in FIGS. 1 and 2 considered below, the support sleeve passing through a circular cutout of a partition is in abutted against it by a radial collar, the other side of this partition being taken upside down by two wings forming tangential projections which start from the support sleeve and are flexible in the radial direction, these ribs being formed on the ribs positioning, this in a symmetrical arrangement, and having their input edges which terminate at a distance from the terminal edge of the support sleeve. It is with a minimum of components that one can compose a "flywheel coupling" in which the possibility of choosing the type of cable outlet at the two ends of the connector is offered with the same 10 components, namely with the element coupling and the profiled retaining part, by means of an appropriate interlocking, this result being obtained by the fact that the contact-carrying part introduced axially in the support sleeve is immobilized axially between the end edges of spouts elastically movable in the direction radial and opposite abutment surfaces, the support sleeve being able to rotate within a limited range and having a portion identical to the corresponding portion of the coupling sleeve and a portion identical to the portion of the support sleeve provided with the groove locking device for the bayonet type junction, and in that the portion surrounds another coupling element at one end of which the contact-carrying part is connected and at the other end 25 of which is connected another profiled retaining part. The invention further provides that a contact piece integral with the support sleeve and provided with the contact pins is provided with a support flange with centering relief which centers it in a cutout. circular of a partition, and that this contact-holding part has a portion identical to a portion of the support sleeve or, as the case may be, to a portion of the locking sleeve This embodiment, illustrated by FIG. 31 commented further on, is preferably used when it is a question of sheltering from water, oil or similar agents likely to be present on the side of the wall corresponding to the coupling of the outer cable , 5 a delicate component, for example a part of an electronic amplifier, arranged immediately

behind the wall of the appliance.

  The invention further provides that all the variants necessary in practice, each with an axial or angled cable outlet 10, can be assembled from an assortment of profiled parts produced by injection molding of high polymers, said assortment comprising contact carrier parts, support sleeves, coupling elements, profiled retaining parts and coupling sleeves. Within the framework of the conceivable embodiments, the invention also provides that, with the exception of the coupling sleeve and the support sleeve of a non-stationary connector, all the components are mutually stopped in rotation by mechanical locking, the contact-carrying part receiving, in a portion of a protective sleeve, the other contact part which penetrates there axially and is provided with a guide groove in which an axial rib of the portion of engagement engages

protective sleeve.

  All the variants shown and each variant which can be produced with axial outlet or angled outlet of the cable 25 (FIGS. 1, 2, 31 and 36) have the following in common: A coupling element 13 and 5 is provided with two retaining pieces profiles 12, 22 for an axial or angled cable outlet, which can be used as desired The retaining parts 12, 22 axially stop the rotating coupling sleeve 11, and are capable of being locked by engagement, 10 under the effect of an axial connection movement, by cylindrical portions ee, with the coupling members 13 d, 13 d ′ of the coupling element At its other end, the coupling element 13 is capable of being coupled to the contact piece, 18 or 15 19 The shell-shaped coupling element 13 has locking tabs arranged diametrically Oblique surfaces of the spouts 13 of locking tabs 13 d correspond to surfaces of oblique attack 12 e, 22 e of the profiled retaining part, 12 or 22, so that, during the axial interlocking movement of the profiled retaining part 12 or 22, the locking tabs undergo a brief radial deformation in order to engage in the holes of locking, 12 i or 22 i, of the connection portion 25 ee of the related retaining part, 12 or 22 The profile K of the contact-carrying part 18, this part having the contact pins 20, is identical to the profile K of the contact piece 19 having the contact sockets ("female contacts") 30 21 The coupling element 13 is provided with a rear retaining profile, H, which can be mechanically coupled with a corresponding profile K of the contact piece (coupling piece) 18 or 19, this coupling being obtained by a relative radial movement 35 between the coupling element 13 and the contact piece, 18 or 19 This relative movement East

  stopped by the coupling sleeve 11 of the mounted connector, this sleeve 11 surrounding the coupling element 13 By a radial profiled collar, 18 a or 19 a, provided with 5 spouts directed parallel 18 e, 18 e ', 18 e "or 19, 19 e, 19 e ', 19 e", the profile K takes the profile H retained on the back by the rear of the coupling element 13.

  In this situation, the 18 th or 19 th radial beak enters the hole 1 pm, and the other beaks, 18 th ', 18 th "or 19 th, 10 19 th", arranged symmetrically with respect to the 18 th radial beak or 19 e, penetrate into notches 13 m from the coupling arc 13 a Frontally, the profiled collar 18 a or 19 a is applied against an annular exhaust 13 e of the coupling element Among other things, this shoulder 15 is formed by the raised side walls of the coupling element, as can be seen in Figures 17

and 19.

  The coupling sleeve 11 is provided with axial ribs 11 ia allowing the fingers to hold it 20 without slipping, and has an overlapping portion ("female portion") 11 b with centering shoulder This coupling sleeve 11 can be linked by locking, by means of a bayonet type junction, to the support sleeve 10 (FIGS. 1 and 2) or 26 25 (FIG. 36) During the locking movement, an internal lug 11 c of the support sleeve 11 is guided in a locking groove l Ob or 26 b of the support sleeve 10 or 26 (Figures 7, 33) During locking, the support sleeve 10 or 26 and the coupling sleeve 11 30 are forced to approach axially from each other, by deforming an O-ring 15, by means of a clamping ramp lob 'or 26 b' of the locking groove l Ob or 26 b In the locking position, the bayonet junction is stopped by a locking relief O 10 c or 26 c which, during the locking movement, is crossed in

  overcoming a friction resistance Thanks to angular stops 11 d, the rotational movement of the coupling sleeve 11 is limited to an angle at the center corresponding to the bayonet junction, said angular stops cooperating with stop edges 13 f of the coupling element 13 In this condition, the coupling sleeve 11 is in abutment, by an annular shoulder 11 f, against a corresponding annular shoulder 131 of the coupling element 10 13, this axially and with the possibility of slip.

  A reentrant portion ("male portion") rear 11 e, having a smaller thickness, is covered by the overlapping portion 12 g or 22 g of the profiled retaining part 12 or 22, and is in axial abutment, allowing sliding, against an annular shoulder 12 b or 22 b of the profiled retaining piece 12 or 22 The profiled retaining piece 22 guides the cable 25 which comes out "in

  square "by a tubular end piece 22 a (figure 24).

  The contact pins 20 are trapped in the contact piece 18, in the region of the partition 18 b (pin mounting partition) The female contacts 21 are immobilized axially in channels 19 c of the contact piece 19, by the fact that they receive an axial support at their rear end and 25 are brought into abutment on counter-supports 19 b using tongues bent outwards The ends

  a are used to connect the cable 25.

  The middle portion 13b of the coupling element 13 serves as a "wiring chamber" in which the strands of the cable 25 are brought to the contact pins or to the contact sockets ("female contacts"), the connector possibly having up to seven

  contact elements, for cable 25 with several strands.

  The exemplary embodiment according to FIGS. 1 and 35 2 relates to a stationary connector, fixed to a partition 27, for example to a machine base. The support sleeve 10 partially passing through a circular cutout in the partition 27 is stopped against the wall. of the latter which takes on the back of the wings lo O g forming 5 projections which leave tangentially from the support sleeve 10 and which can be flexed radially These wings 10 g arranged symmetrically are formed on positioning ribs 10 f arranged at the ends of a diameter on the support sleeve 10 and extending 10 axially between the end edge thereof and the radial collar 10 a These positioning ribs 10 f have at their ends a bevel 10 d ", as can be see it in particular in FIG. 7 The wings 10 g are provided with oblique entry edges 10 g ′ which terminate at a distance 10 from the end edge of the support sleeve 10, as can be seen in the figure 4 Leading edges 1 0 g 'have the effect that, during the introduction of the support sleeve into the circular cutout of the partition 27, the wings are biased by the edges bordering the cutout and are thus elastically bent and brought back to the radius of the sleeve d 'support, so that during the axial movement thereof they can pass through the cutout of the partition until, the radial collar 1 Oa being in abutment 25, they are released from the partition and return elastically to their initial position The rear edges of the wings lo O g which are also oblique then apply firmly against the edge of the edge of the cut-out of the partition 27 The obliquity 30 allows fixing against partitions 27 having

  various thicknesses: depending on the thickness of the partition 27, it is at a greater or lesser distance from the positioning rib 10 f that the edges of the wings l O g are applied against the edge of the edge of the cutout 35 in partition 27.

  Introduced axially in the support sleeve

The plug-in connector described is advantageously usable when, for example, very delicate electronic components situated behind the partition 29, have to be protected against the entry of water, oil or the like The sealing seal required for a t protection is obtained by means of a sealing ring 28 arranged in an annular groove 23 d of the support flange 23 c The contact pins 20 are taken in the holding wall 23 b and are projecting in the contact room, 23 a. As the means of protection against the mechanical tensions of the cable are arranged in the coupling element 13, they are produced identically in all the variants: these means of protection against the mechanical tensions have a clamping range 35 13 c extending between the wiring chamber and

2551 271

  the rear end of the coupling element The clamping range 13 c is provided with transverse ribs 13 n The cable placed in the clamping range 13 c is clamped against it using a clamp 5 for absorbing tensile forces, so that the transverse ribs 13 N can penetrate the cable jacket, for axial immobilization The bracket for absorbing tensile forces is screwed to the coupling element 10 by means of screws 17, the heads of which find

  counter support on abutment surfaces 13 g.
