Description

State of the art The invention relates to an electrical device for

  connection with a connector and an opposite connector which can be coupled with the first, the opposite connector being constituted in the form of a cable harness connector and the connector being constituted in particular in the form of what is called a strip knife contacts. A connector of this type is known from the document

(DE 33 10 477 Ai).

  Such known electrical connectors have a rule, of knife contacts, the contact elements of which are inserted in the form of connection pins on one side into the connector housing and which are brought out on another side of the housing. of the connector. The input side and the output side have an invariable arrangement in this case. This has the consequence that in the event of a possibly necessary change of the entry or

  another connection must be used from the output

  tor. -As the connectors with their numerous contact elements and with their fixing seal are relatively expensive, a corresponding special manufacture

is antieconomic.

  The object of the invention is to avoid this inconvenience.

  deny and create a connector that is universally used

  readable. In this case, the connector must be small, light and simple to assemble and it must be able to be easily adapted to

  different installation conditions.

  This problem is solved according to the invention thanks to the fact that the connector has a connector body and a

  bridge-shaped holding device for the body

  nector and in that the connector body can be fixed on a mounting plane of the sleeve device in a large

  number of positions, in particular angular positions.

  This is how it is for example advantageous that

  the contact elements are formed by cable sections

  ble smooth. They are simply cut from a roll of

  cable and sealed in the connector with a plastic material

  than. In addition, it is advantageous for the flexible sheet to be turned over, because in this way there is greater freedom of movement for the body of the connector when its position on the holding device is varied. he is also

  advantage that the connector body has play on its dis-

  positive retention in the fixation plane, because of this

  way we can compensate for the tolerances with respect to a

  ring covering the connector body. It is also advantageous that even when the possibility of inverting the body

  of the connector is not enough to take into account the different

  mounting conditions, you can also modify the holding device. A modification of the holding device made of a cheap plastic material is in any case more economical than having to modify the body of the

  connector that has a lot of value. The great degree of freedom

  tee for the corresponding position of the connector body on

  its holding device is important because it can be modified

  proud both in the longitudinal direction and in the direction

  also across the flexible sheet and even in the

  corresponding intermediate positions.

  It is also advantageous in the case of a mode

  of the two-part holding device

  ready, that the basic free bars of the

  can be used as a support for a bou-

  protective shield and / or a protective cover for the

  flexible sheet and / or for contact elements. Final-

  It is advantageous that, thanks to the particular arrangement

  lière of the flexible sheet providing a large degree of freedom, returned to 180, it is possible in a single machining phase after turning the connection body

  to carry out a soft soldering to the wave of the elements of

  tact as also of the control unit to be connected, as

also other actuators.

  According to other characteristics of the invention: - the connector body has at least one series

  contact elements that are mounted and held solid-

  lying in a central area in a sealing bed available

  laid down in the connector body.

  - the contact elements are formed in the form of

  connection pins in the form of smooth sections of cables.

support.

  - the connector body has an annular groove which is designed to receive an O-ring and in that the

  O-ring cooperates with an internal partition of a cover

  key. which engages on the connector.

  - the connector body can receive in particular four angular positions and in that it has for this purpose four

  plinth strips which are respectively arranged at an-

  right with respect to each other about an axis.

  - among the four plinth strips, respectively two

  pedestal clips which face each other are used

  wind of plug-in mounting base strips, by means of which the connector body can be threaded into the

  bridge-shaped holding device and it can be re-

  link in this way to the holding device.

  - the plinth strips are in cross section consisting of

  killed in L shape and each have a snap groove. - the bridge-shaped holding device has two U-shaped guide rails in cross section, facing each other, with two elastic hooks and in that each elastic hook cooperates with the one of the two latching grooves in such a way that the connector body can be slid onto the holding device

shaped like a bridge and fixed on it.

  - each elastic hook has lateral play in the groove

  associated latching to compensate for tolerances.

  - the connector body is arranged at least in a wide

  measurement at the center of the holding device.

  - the connector body is offset laterally-

  relative to the holding device.

  - the bridge-shaped holding device has a

  0lo stop slide for the connector body pressed.

  - the bridge-shaped holding device is made up

in one piece.

  tacts, located on the connection side, of the connecting elements

  tact. - the bridge-shaped holding device is made up

without connection in two parts.

  - a protective shield fixed on one of the two free base strips of the connector body assumes the function

  for protecting the bridge-shaped connecting piece.

  Description of the exemplary embodiment

  Device for electrical connection to a connector

  tor 1 constituted in the form of what is called a re-

  knife contact block with a bridge-shaped holding device 2 and with a connector body 3 placed thereon. A mounting plan for the connector body 3 on the holding device 2 has the reference numeral 4. The holding device 2 has four fixing eyelets 5 for fixing it to a part of the vehicle not

  shown and two guide rails 6 and 7 facing each other

  screw, having a U-shaped cross section with res-

  pectively an elastic hook 8 or 9 that can be seen in Figure 3 closed above. In addition, the holding device 2 has a stop strip 10, on which the body of the connector 3 is supported after being inserted into the

  two guide rails 6 and 7. It is important that the posi-

  tion of the guide rails 6 and 7 and the stop strip 10 can be provided in the case of different mounting conditions

  respectively respectively by modifying the mold

  jection; in the case of the embodiment, their position is chosen so that an axis of the body of the connector

  3 is located in the middle on the holding device 2.

  The holding device 2 can be either

  formed in one piece, it then has a connecting piece 12 formed above between its two guide rails 6 and 7 in a U shape. This embodiment is shown in FIGS. 1 to

  3. The holding device can however also be reali-

  dried in two parts without connecting piece 12, as indicated

shown in Figures 4 to 6.

  The connector body 3, fixed on the device

  support 2, is a complicated and expensive part. We cons-

  for this reason it always works the same way for all possible applications and it can be used universally. This also simplifies maintaining the position of the

connector body 3.

  The connector body 3 has inside four rows of contact elements 13 formed in the form of

  connector pins, total 38, which are arranged symmetrically

  tracing with respect to axis 11 and are oriented parallel-

  to this one. The contact elements 13 are simple sections of cable of the same length. The contact elements 13 can however also be produced with circles. They are embedded and sealed in the body of the connector in a sealing bed 41. On the opposite side of the connector, they are brought into contact in a manner not shown, but of known type

  with a cable harness connector. On the connection side

  dement they project above the mounting plane 4 and

  above a bearing surface 14 of the body of the connector 3.

  The bearing surface 14 has, as can best be seen in FIG. 7, two flat fields 15 serving to lay a flexible sheet 16, which is connected by the free ends of the

  contact elements 13 in a particular work phase

  lière, which will be described later. The elements of con-

  tact 13 can however be connected to a stamped mesh

instead of flexible sheet 16.

  The body of the connector 3 is surrounded in the center with respect to the axis 11 by an annular groove 17, which is designed to receive an O-ring 18. This O-ring 18 serves to seal against a cover (not shown), which covers connector 1 upwards. Also, centrally with respect to the axis 11, the connector body 3 is provided with four base strips 19, 20, 21 and 22 which are respectively arranged at right angles to each other. Two base strips 19 and 21 or 20 and 22 which face each other serve as plug-in base strip strips, that is to say a mounting without screws, with which we can

  press the connector body 3 into the handgrip

  your 2 in the form of a bridge and you can connect it in a solid way

  in this way to the holding device 2 and in this way to the holding device 2. It can be seen that the body of the connector 3 can in this way take four different positions on the holding device 2. In this case another configuration of connector body 2 you can have six, eight or twelve different body positions

connector 2.

  The base strips 19 to 22 have their L-shaped cross section and have a width which

  does not exceed the width of the other base strips available

  placed respectively at right angles to them. In the center of the width of each base strip 19, 20, 21 or 22, a catch groove 23, 24, 25 or 26 respectively is provided. Each catch groove 23, 24, 25 or 26 is designed to cooperate with one of the elastic hooks 8 or 9 of the guide rails 6 and 7, as can be seen at

better in figure 3.

  In this figure we can also see that each

  that elastic hook 8 or 9 has lateral play 27 relative to

  to its snap groove 23, 24, 25 or 26. This has the reason

  following sound: the fixing of the connector body 3 on the holding device 2 is in fact determined and fixed without hindrance horizontally on the mounting plane 4. In the mounting plane 4, the connector body 3 must however be able to move laterally relative to the holding device 2, to compensate for the tolerances caused by the manufacturing between the fixing eyelets 5 and the axis 11 of the connector body 3. To make this lateral movement possible, various measures have been taken, providing clearances , on 10 the binding and firstly the set 27 already mentioned,

  secondly a clearance 28 in FIG. 1 on the bottom of the rail

  nure of the U-shaped guide rails 6 and 7, and a clearance 29 in the area of the holding strips 34, 35 in the case of the

  separate holding device according to Figures 4, 5 and 6.

  The last figures mentioned 4, 5 and 6 my-

  trent also that it is possible to devote to another use

  reading the two base strips 19 and 21 or 20 and 22 respectively not used for holding and in fact on one

  free base strips, a protective shield is fixed

  tion 30 also with an elastic hook 31, the elastic hook 31 being disposed however without play in its groove

  latching. The protective shield 30 serves as a substitute

  tut to the connecting piece 12 which is missing in the case of the two-part construction method of a holding device

  and is like this piece designed to protect the bonding

  subsequently read by soldering between the connecting elements

  tact 13 and the flexible sheet 16. According to a development of this idea of protection, the other base strip, also not used for holding, also carries a bent piece 32, which covers the 180 ° elbow of the flexible sheet by protecting it. 16. This bent piece 32 also has an elastic hook without play 33. The protective shield

  and the bent part 32 also have a fixing bar

  tion 34 or 35 by which they engage from behind

  almost without play with the plinth strip which corresponds to them

  pond, to give them better support on the body of the connector 3. The protective shield 30 and the bent part

  32 have a width at their fixing locations which

  corresponds to the width of the base strips 19 to 22. In the rest of their journey, however, they are provided with a greater width 36 or 37, to improve their protective function. Figure 8 shows the connector body 3 rotated 180. The flexible sheet 16 previously bent, is

  then finds, starting from the contact elements 13, smooth in a brazing plane 38. The flexible sheet 16 is then brought to an electronic control device 39 and to other actuators 40 not shown in detail. In this brazing plane 38, the body is arranged and prepared

  nector 3, the control device 39 and the other actuators 40 for soft wave soldering, which is particularly simple and economical.15 It also falls within the scope of the invention to

  push in and snap in the connector body

  3 on the bridge-shaped holding device of a

  other than that described, for example by threading

  various ways on nipples or the like.

  It is also conceivable to use the invention for other connector systems instead of a system

  component of a connector (blade contact strip) and of an opposite connector (cable harness pins). As an alternative to the flexible sheet 16, it is also

  It is also possible to have another contact support, for example a stamping grid, which is connected to the bar.

  of knife contacts so as to make contact.

  An injection tool for the connector body 3, according to the invention, (knife contact strip) is

  economical, because one of the types of contact strips

  teaux can be used for several products. Regarding the position of the blade contact strip or the cable harness connector there is a high degree of

  freedom. In connection with the flexible sheet 16, it is

  particularly advantageous to have a common soldering of all

  the contact elements 13 in a plane and a work phase

  vail. The contact elements 13 can be produced both in the form of cable sections, as well as round. Finally, the tightness of the connector 1 is simple to design, because a seal is used only

single O-ring 18.
