Description

The invention relates to an electrical plug connector

  sheet having a male plug part fixed in a module housing, in the direction of its longitudinal axis, a

  against plug, can be coupled to the plug part

  , and a rotation safety device arranged on the part with male plugs, preventing any directed rotation movement

  around the longitudinal axis of the plug part.

  Known plug connectors or connectors

  electric torers equipped with a rotation security arranged on a part with male plugs, security which engages in a

  housing wall, for example a transmission wall with

  grenage. Having a separate rotation security is necessary

  especially when the plug part which is integrated in a module housing is likely to rotate on its longitudinal axis due to the shape for example

  round and circular in its cross section, in a per-

  mounting hole of the male plug part, relative to the box

  tier of the module. The additional rotation safety limits the rotary movement on the longitudinal axis and therefore prevents that, following the rotary movement of the plug part

  males, tensile or compressive forces, or

  ples are transmitted to a wiring arranged on the rear side on the male plug part or on solder or soldering points. In the known electrical plug connector, there then occurs in principle the problem that the various elements of the electrical plug connector are

  bound by manufacturing tolerances, the position of the con-

  plug nector relative to the gear transmission housing being adaptable only insufficiently due to rotation security, so that the mounting of the connector to

  electrical plugs compared to the housing is expensive and com-

  plicated. The object of the invention is to indicate an electrical plug connector of the cited type which, when the male plug part is mounted in a housing or else on a socket fixed to the housing, can be adapted to its position without problem of the point of view of tolerances on a component or

  can be adapted to integrated drilling.

  This problem is solved according to the invention in that the rotation security has a clearance compensation means, allowing, relative to the housing, a displacement of the plug part perpendicularly to

the longitudinal axis.

  Rotation security provides a means of

  game thinking that allows, compared to the housing of the

  gear transmission, displacement of the part to be-

  male, perpendicular to the longitudinal axis

dinal.

  According to the invention it has been identified that a displacement

  cement, when mounting the male plug part with respect to

  port to the housing, perpendicular to the longitudinal axis of the plug part and thus also

  perpendicular to the direction of assembly with thread

  chage of the plug connector, offered decisive advantages.

  Any tightening or jamming of the plug part can therefore be avoided during assembly. Precisely, in the case of a mounting position of the plug part in which there is a bypass by a fluid sweep,

  for example in the case of a gearbox transmission

  swimming filled with oil, preferably we use grids

  stamping to obtain electrical contact.

  Because the grids coming from stamping are mobile with their flat tracks only within a certain limit here,

  also, the displacement of the male part relative to

  port to the longitudinal axis of the plug connector can easily

  ter any soldering or soldering of the contacts or else prevent

  harmful efforts are manifested at the connection points.

  Another advantage of the invention lies in the

  fact that component tolerances can be compensated

  sées within certain limits by a displacement of the plug part relative to the housing. Another advantage can be appreciated in that, when using a socket comprising sealing elements in which the plug connector can be integrated, the insertion of the part

to male plugs is improved.

  According to the invention, the rotation security can, already at the stage of manufacturing the housing, be fixed in its position relative to the housing and the hole for mounting

  of the male plug part to be provided in the housing.

  Thanks to the fitting of a socket with sealing elements

  tee, we can then have, perpendicular to the longitudinal direction of the plug part, often

  small deviations from the optimal position of my

  tage of the male plug part. These differences are compensated

  particularly advantageously by means of compensation

  tion of game according to the invention, which can be part of the

rotation security.

  According to a first improvement of the invention, the rotation security has connecting elements with shape adjustment. The connecting elements with adjustment of

  form according to the present invention are all the techniques

  linkage with the possibility of separation which prevents

  cost any rotation of the plug part relative to

  to the housing parts, this by means of an adjustable link

  mentally shaped acting in one direction or in the direction of rotation. Preferably, on the rear face of the male plug part, therefore on the connection side opposite to the male plug contacts, is provided a stud which engages in a recess or a groove in the housing. The post can then be a multi-sided element or a double-sided element, which can be extracted from the recess or the groove, in the longitudinal direction of the plug part and which, on the other hand, stops the rotational movement around

  of the longitudinal axis of the plug part.

  Preferably, the rotation security has a sliding disc which can be fixed on one side,

  by a link with shape adjustment on the part to be

  male ches and, on the other side, by a link with adjuster-

  form on the module housing. According to the invention, the

  sliding disc can be used to bridge the dis-

  existing between the rear face of the plug part

  plugs and a module housing wall. The coulis- disc

  Preferably, it can be detached in the direction of the plug part, the connection with adjustment of

  shape, for example between a post having a cross-section

  dirty rectangular and a rectangular groove, preventing

  any rotational movement of the sliding disc with respect to

  port to the male plug part and any rotational movement of the sliding disc relative to a module housing wall. In this way, the male plug part is

  fixed on a housing wall, the post provided on the rear side

  rière, for example a two-sided or a multi-sided element, preventing any rotational movement relative to an area of the housing wall, for example a second wall

  housing disposed behind the male plug part.

  According to a particularly advanced development

  tagger of the invention, rotation security has a

  first post which engages in a rectangular groove

  swam on one side of the sliding disc, and another

  no, made on the opposite face of the sliding disc, which engages in a groove or a recess in the housing. In this way, the link with shape adjustment is easy to assemble and separate again, in the longitudinal direction of the plug part and, when assembling the module housing parts, it remains maintained between the walls. case. However, the form-fitting connection can also be achieved in another way. For example, a groove may be formed on the rear face of the male plug part in which a tenon belonging to the shoemaker wall engages.

  or a sliding disc. On the other hand, also, the se-

  rotational curity can be arranged laterally on the male plug part, a lug also engaging then

in a groove.

  According to another advantageous improvement, the connection of elements with shape adjustment present, in at

  minus a direction perpendicular to the lon-

  gitudinal of the plug part, a clearance, in a plane perpendicular to the longitudinal axis of the plug part

  males, at least on one face of the post, existing a limited space

  bre along which the post can move with the male plug part, in one direction. To this end, observing in the direction of movement, perpendicular to the longitudinal direction of the plug part

  male, the recess or the groove is of a cross section

  dirty larger than the tenon. The groove or the recess

  ment then constitutes a lateral free space for the movement of the post which, in particular is linked to the part

  with male plugs, this along the guide edges of the rail

  nure. The groove can for example, on two opposite faces of the

  post, present two free spaces which allow a movement

  cementing the post each time by one millimeter in one direction

  tion and one millimeter in the opposite direction, by

compared to the normal position.

  Preferably, the play compensation means consist of the tenon movable in a groove, in particular by a two-part element constituting the connecting element with shape adjustment intended for rotation security. Following this, by providing the free spaces for the movement of the post, it simply provides the rotation security of the clearance compensation means according to the invention. According to another improvement of the invention, the clearance compensation means have two connections

  of form adjusting member having directions of com-

  play thinking arranged perpendicular to each other, for example the sliding direction. Precisely in connection with a sliding disc which has two

  form-fitting element links, as described below

  above, a tenon can on one side of the sliding disc

  be movable in one direction and in the other in a direction

  tion perpendicular to the longitu-

  dinal of the male plug part, and on the other side of the

  sliding disc, one tenon, arranged on the part to be

  male pins, can be moved in the groove, in another direction which, in particular, is perpendicular to the longitudinal axis of the male plug part and

  perpendicular to the first direction of travel

  cementing of the first tenon on one side of the sliding disc -

  is lying. Due to the perpendicular arrangement of the two play compensation devices, the plug part is ultimately displaceable in any direction with respect to the rotational safety and thus with respect to

the rear housing wall.

  Preferably, the rotation safety device equipped with the play compensation means has two connections of shape-adjusting elements, with two studs arranged perpendicular to one another, in particular produced in the form of elements with two sides which are movable along two recesses which have free spaces

  intended for moving the studs.

  The male plug element may have

  electrical tacts, in particular male plug rods which are capable of being brought into electrical contact on the opposite connection face, in particular with a grid coming from stamping. The male plug part can also have small sockets or clip elements to receive male plug rods which adapt and belong to

  the conjugate part for male plugs. In addition, the connections

  elements that can be brought into contact with the grid coming from

  stamping or with corresponding cables can also

  also be arranged on a face or the peripheral surface

than the male plug part.

  Preferably, the male plug part has

  on the connection side a covering means which overlaps

  at least partially cover the connection side and / or the cable

  blocking, for example the grid coming from stamping. The covering means covers at least zones on the rear face of the male plug part or of the connection face, as well as the points of contact between the male plug rods and the grid coming from stamping, or also covers parts of the grid coming from stamping itself. Thanks to the overlap, it is possible, on the one hand, to provide protection for the soldering or soldering points on the connection side.

  of the male plug part and one can, on the other hand, increase

  lie about the mechanical stability of the connection between

  the grid from stamping and the male plug part. In-

  end, the covering means can act as an insulation

  for connection contacts and the grid coming from

  stamping, especially also in conjunction with other parts

  housing or other insulation.

  The covering means preferably has

  one of the connecting elements by adjusting the shape of the

  rotational curity, in particular a groove or a double-sided element. In this way, the efforts occurring on

  rotation security can act, on the one hand, on the

  tie with male plugs and, on the other hand, on the wiring or the grid coming from stamping. The tensile forces and

  of compression occurring upon contacting the con-

  tacts by male plug are thereby reduced.

  According to a particularly advanced development

  tagger of the invention, the covering means is made in one piece by injection on the connection side on the male plug part. In the connection area, the stamping grid and the plug contacts are coated

  by injection with a link involving ef-

  strong, by plastic. During this process, on the free front face, an element is simultaneously constituted

  two-sided, optionally with a horizontal mounting position

  tale or vertical to the housing. On this two-sided element, the sliding disc can then be placed

  having a groove surrounding the two-sided member.

  Preferably, the plug connector has a socket connected to the male plug part and to the conjugate part for male plugs, in particular equipped with means

  sealing to insulate tightly from the box

  tier. It is also possible to provide additional sealing means.

  between the male plug part and the socket or between the socket and the conjugate plug. In particular, when mounting the plug connector according to the invention in gear transmission boxes in which is located

  oil for the gear transmission,

  be the housing parts, the socket, and the plug part

males is required.

  The socket may have a rotational safety

  tion, in particular obtained by means of a toothing or a tenon, with respect to the male plug part or to the housing. Therefore, in the mounting position, especially for

  plug connectors having a cross section

  Dant a rotation symmetry or circular, any rotation of the sleeve relative to the plug part

males is excluded.

  In addition, the socket can be provided by the

  by means of a holding means, in particular a ring

  elastic or an elastic clamp, to prevent any displacement-

  parallel to the longitudinal axis of the plug part

males.

  The sleeve provided in rotation may have a coupling means, in particular a screw or rod closure, to prevent any inadvertent uncoupling

of the plug connector.

  Two embodiments of the invention are shown in the drawings and are described below. They are represented schematically: * Figure 1 is an exploded representation of a first

  embodiment of the electrical plug connector se-

  ion the present invention, * Figure 2 is a representation of the plug connector

  electrical assembly, according to the first embodiment

  tion, and * Figure 3 is a sectional view of an electrical plug connector, according to a second embodiment according

the present invention.

  The electrical plug connector according to the pre-

  mière embodiment has a male plug part 1 equipped with male plug rods 2, connected, by a base for male plugs 3, to a housing 4 in which is integrated an electronic control 10, for example to attack a box of motor vehicle gears. Box 4

  is integrated directly into a vehicle gearbox

  automobile, so that the housing 4 can be enveloped in a flow of gearbox oil. On the housing 4 are provided electrical connections 5, 6 intended for the

  pre-order valve control. Alternatively, the soupa-

  Pre-order pes can also be integrated into the module as well. In addition to the related control electronics, there may be sensors for understanding the rotational speed, a stroke, a pressure and performing the temperature measurement. Inside the housing 4 is in

  besides provided a grid coming from stamping 7 equipped with dif-

  different conductive tracks 8 to ensure the connection

  electrical control electronics 6 with the

  male plug rods 2 of the male plug part 1.

  The electrical plug connector is present

  be a rear wall 12 of socket of male plugs with a stamping grid guide part 13. The rear wall of socket socket 2 is produced, relative to the plane of the stamping grid guide part 13, under the shape of a plastic part arranged so as to project perpendicularly. The rear wall 12 of the base of the plug has a base plate 14 having a closing zone 15 in the shape of a semicircle, equipped with parts of

  frame 16 angled relative to base plate 14.

  The base plate 14 has stamping grid guide elements 18 located internally, which provide a spaced arrangement of the conductive tracks 8 of the grid coming from stamping 7. The guide elements of

  stamping grid allow to have a movement of displa

  cement, in particular oriented towards the inside of the box

  tier 4, from the stamping grid 7.

  The stamping grid guide part 13 is rigidly connected to the rear wall of the socket base 12 and is adapted to the shape or the shape of the stamping grid.

  7 and is provided with other guide elements guiding

  stamping 19 to allow a defined displacement

  of the stamping grid 7 in a direction of

  predetermined placement, for example horizontally or vertically

  tically, the different conductive tracks 8 being spaced

ceded and isolated from each other.

  Preferably, the stamping grid 7 has in its shape one or more inflection points 20, to allow an extension or a shortening of the conductive tracks 8, in order to obtain an adaptation of the stamping grid 7 to the position of the pins of male plugs 2 when brought into contact. The rear wall 12 of the socket, present in the base plate 14, preferably at

  inside the connection zone 15 in the form of a half

  circle, a recess 22 or an elongated groove in the direction

  vertical in the example. In the elongated recess 22

  can be inserted a sliding disc 23 fitted with a

no two-sided 24.

  Both the recess 22 and also the tenon in two-

  sides 24 are made elongated, the arrangement 22 having

  an extension in length greater than that of the tenon to two-

  sides 24. If the longitudinal extension of the recess 22 is at

  about 2 mm larger than that of the two-post

  sides 24, then the sliding disc 23, in the direction

  longitudinal position arranged in particular vertically, is movable from a central rest position, on

  a distance of approximately 1 mm in each longitudinal direction

  nale, i.e. 1 mm upwards and 1 mm upwards

low.

  The sliding disc 23 has on a

  face 25 opposite to the two-point tenon 24 a groove 26 allon-

  gée, the longitudinal extent of which is arranged in a di-

  rection perpendicular to the longitudinal extent of the two-point tenon 24. The groove 26 has a longitudinal extent greater than that of a two-point tenon adapting thereto. The longitudinal extent of the groove 26 is

  in the example 2 mm higher than that of the two-post

  sides 31. The sliding disc 23 is produced under the

  shape of a circular disc having two flat faces, the te-

  no two-sided 24 being disposed on a first flat face

  and the recess 26 on the opposite flat side 25.

  1i The plug-in part 1 presents a

  substantially cylindrical shape, is made so as to re-

  lay a rotational symmetry with respect to its long axis

  gitudinal and therefore can rotate without the rotation security 22, 24, 26, 31 with blocking effect, in the housing of

  male plug part 27 formed on the socket 3.

  The male plug part 1 has on its periphery a

  rib or a peripheral tier 28 around which

  in the mounted position, the plug part 1 in

its longitudinal direction.

  In principle, it is now provided that, on the rear face of the plug part, a hexagonal pin 31 is arranged which engages in the groove 26 of the sliding disc, so that the plug part male 1 is fixed with a form fitting link in the groove

  26 of the sliding disc 23 and is movable simultaneously-

  lie in one direction and in the other in the longitu-

  dinal of the groove 26. To this end, the groove 26 has in its longitudinal direction again a greater extent than the tenon connected in a manner subject in rotation to the

  housing side 29 of the male plug part 1.

  In the present embodiment, the rods

  of male plugs 2 are connected each time to a track

  duct 8 belonging to the stamping grid 7 in the area

  of connection 21 this being done by welding and braiding

  wise or riveting. In the connection zone 21 both the stamping grid and also the plug part 1 are connected with a force interaction link, by

  example coated by injection with plastic.

  During the production of the covering means 30,

  read, on the free side, facing the slide disc -

  ment 23, connection means 30, a two-point tenon

  31, so that it fits snugly with the rai-

  nure 26 of the sliding disc 23. The two-point tenon 31 and the groove 26 are then made so as to have a clearance of about 1 mm in the direction of movement and a

  very small clearance in the direction perpendicular to the line

* nure. As a result of this, the male plug part 1 can be moved in a direction, for example horizontal relative to the sliding disc 23 and the plug part

  male 2 can be moved together with the disc

  smoothing 23 in a direction which, in the example, is vertical with respect to the recess 22 formed in the wall

  rear 12 of the socket with male plugs. In this way, the par-

  tie to male plugs 1, during subsequent mounting, for example,

  can be moved in the housing wall or alternatively

  port to a socket, in a plane perpendicular to the longitudinal axis, the displacement being approximately 1 mm

  in each direction, to cause compensation for to-

  without turning the plug part with the

related conductive tracks 8.

  In Figure 2, the electrical plug connector

  that according to the first embodiment is assembled and,

  therefore, is made in the form of a component of the box

  tier of module 4. The plug connector can then be dis-

  placed mobile between two plastic housing parts 3 and 12. When inserting the conjugate plug not shown in the male plug part, by means of the rotation safety device according to the invention, it is possible to move with

  a balancing of play the part with male plugs in a posi-

  tion perpendicular to the longitudinal axis, the as-

  appearance by plugging in the electrical plug connector being facilitated. For example, component tolerances caused by seals 40, 41, 42 and parts of plug connectors can be compensated for, and even the tolerance for

  mounting between the module housing 4 and the trans-

  gear mission 47. The conjugate piece for plugs is usually connected to a cable harness of the vehicle. For

  mechanically reinforce the socket for plug 3 has a

  pui 32 which is arranged parallel to the longitudinal axis of

the card section.

  In Figure 3 an electrical plug connector is shown in section along the longitudinal axis 34, this

  connector being made according to a second embodiment

  tion of the present invention. Components which coincide with the first embodiment have the same

  reference characters. The male plug part 1 is produced by responding to rotational symmetry with respect to its axis

  longitudinal 34 and can be inserted into a hole 35

  by means of a socket 36. The male plug part 1 pre-

  feels, on a connection side 29, a peripheral

  risk 33 intended for anchoring the covering means 30 and, on its face pressing directly on the housing 4, a socket housing zone 37 which emerges radially. Between the socket housing area 37 and the periphery tier 33 is

  constituted by a peripheral groove 38. The peripheral tiering

  rique 33 and the peripheral groove 38 constitutes the root point for the covering means 30 which is fixed either by a connection by force interaction, or by a form-fitting connection on the side of the connection 29 on the plug part 1 , for example by a plastic injection molding process. The covering means 30 surrounds the parts located on the connection side of the plug pins 2, the connection points and a part of the stamping grid 7. The covering means 30 has, on the one hand, a function of insulation and, on the other hand, the forces acting on the stamping grid 7 must be eliminated by the displacement of play and tolerances of the electrical plug connector of the locations of the connection points, and be deviated directly from the plug part males 1 on the

stamping grid 7.

  The male plug part 1 presses from its

  mite opposite to the connection side 29, that is to say by a part of the socket housing area 37, directly on the inside face of the housing 47. An annular groove 39 is provided in the socket housing area 37 on the front face of the male plug part 1 for threading the male plug part 1 from one side onto the socket 36 fixed in the

drilling 35.

  The bush 36 has two sealing rings and 41 which provide a seal relative to the housing 47, and a seal ring 42 which provides a seal

  compared to the male plug part 1. The socket 36 pre-

  feels a peripheral stage 43 disposed outside the

  housing 47 and pressing externally on housing 47,

  which prevents the socket from ripping parallel to the di-

  longitudinal section to go inside the housing. The sleeve 36 is provided by means of an elastic clamp 44 in addition against any extraction from the bore 35 of the housing 47. The elastic clamp 47 can also, in addition, secure the sleeve 36 in the annular groove 39 of the plug part

  males 1 against any displacement relative to the longitu-

line 34.

  On the inner face of the annular groove 39 is provided a rotation security 45, for example a toothing or a tenon engaging in a groove, to prevent any rotation of the sleeve 36 around the longitudinal axis 34 relative to the part with male plugs 1 ensured in rotation. On the face disposed outside the housing 7, the socket 36

  has parts of a 46-bayonet closure intended for

  born to fix the conjugate socket on the

  socket 36 and thus also on the male plug part 1.

  The sleeve 36 facilitates on the one hand the waterproof insulation with respect to the housing 47 and has an additional guide intended for the conjugate piece for plugs during insertion.

in the male plug part 1.

  With the two-point tenon 24 located on the rear side

  the entire electrical plug connector including

  of the combined grip ensured in rotation by means of the iron

  gagging is ensured against any rotation by

  relative to a rear wall 12 of the housing. The means of

  game compensation thought according to the invention are cons-

  formed by two links of shape-adjusting elements 22,

  24, respectively 26, 31 of the sliding disc 23,

  can be placed in two directions perpendicular to each other

  be. Due to the rotation security 22, 23, 31, 45 according to the invention with clearance compensation means, the plug part 1 is mounted between the rear wall 12

  of the male socket and the gearbox

  swim 47 so that the plug part 1 is

  hardly or not movable parallel to the longitudinal axis 34, however knowing that a movement of displacement in the radial direction relative to the male plug part 1, that is to say in the plane perpendicular to the longitudinal axis 34 is possible. In the radial direction, the

  ment is delimited, on the one hand by the housing of the male plug part 27 and, on the other hand, by the rear wall 12 of the socket of male plugs, rear wall on which the part with 10 male plugs abuts with its periphery. The limitation of the axial displacement is effected by a stop of
