Definitions

  • the invention relates to a plug connection for electrical lines with a first and a second connector part, the two connector parts containing a plurality of contact elements and fitting elements for external coding, which must come into operative connection with one another in order to join the two connector parts.
  • Such plug connections are used to avoid undesired connections between the same connector parts if only certain conductors or contact elements may be connected to one another by means of the connector parts.
  • the coding ensures that only the connector parts assigned to one another by a corresponding selection of the fitting elements can be connected to one another.
  • a transfer connector system for electronic controls or devices is known, by means of which the lines of cables are connected to the connections of printed circuit boards which carry electronic components and are arranged parallel to one another in magazines (EP-OS 128 307).
  • the known transfer connector system contains Multiple connector parts, each of which is held by a cable housing.
  • the second connector parts are fastened in or on a holder.
  • On both sides of the cable connector housing a number of rectangular pockets with internal recesses are formed, the front parts of which can be broken out.
  • receptacles for receiving legs on locking elements are provided, opposite the ends of the pockets and axially parallel to them, the leg ends of which contain hooks and which are fastened to the cable connector housing by a snap-in connection.
  • Printed circuit boards with electrical or electronic components are often connected to a backplane circuit board on which the conductor tracks for the mutual connection of the connections of the individual circuit boards are arranged. Lines or cables to external units or devices also extend from the backplane wiring board.
  • the backplane which e.g. formed in multilayer technology, can be provided with press-in pins, which if necessary form contact with metallized holes in the backplane.
  • the press-in pins protrude beyond the printed circuit board levels on both sides.
  • frames surround parallel rows of press-fit pins, which are arranged at a distance from one another which is defined for plug connectors.
  • the frames serve as a guide for female connectors that are connected to the circuit boards.
  • spacers can be arranged at the ends of the parallel rows of press-in pins, on each of which further frames are fastened.
  • male connectors are attached to the rear wall printed circuit board which runs transversely to the printed circuit boards and which are straight Contain pins that protrude through holes in the backplane and are surrounded by their protruding ends in rows of guide frames for female connectors, in which multiple connectors can be used, each of which is connected to a cable connector housing.
  • male connectors can be attached to the front faces of the printed circuit boards, which are surrounded by a guide frame adapted to the dimensions of the front plates of the printed circuit boards, into which a multiple plug connected to a cable connector housing can be inserted.
  • the multiple plug is designed as a female connector with insulation displacement contacts that interact with a cable routing part.
  • the female connector and the cable guide part are arranged in a cable connector housing composed of two half-shells.
  • the mating connector or second connector part consists of the pins of the male connectors and the respective guide frame.
  • the sockets for the locking are each arranged in a row next to each other in two lateral, strip-shaped projections of the guide frame.
  • the hooks protrude beyond the sockets. Due to inclined guide surfaces on the projections, forces acting in the direction of the longitudinal axis of the sockets are transmitted from the spring-loaded locking elements. These forces pull the locking elements against the sockets, the stops of the hooks engaging the projections. The locking elements are thus fixed in their position.
  • a bent section of the locking elements adjoining the legs lies in the gaps of the broken-out front parts of the pockets when the position of the respective locking element along the guide frame matches the broken-out front part of the pocket on the cable connector housing. If no front part of a pocket is removed from the cable connector housing at the position occupied by the locking element, this indicates that the multiple connector in the cable connector housing and the guide frame are coded differently.
  • the invention has for its object to further develop a connector of the type described above that regardless of the coding chosen for the attachment of the cable connector housing to the mating connector, a high connecting force is available.
  • the object is achieved by the features of the characterizing part of claim 1.
  • all legs are engaged with the sockets.
  • a much larger and more uniform force is transmitted between the locking elements arranged on both sides of the cable connector housing and the mating connector element.
  • a locking hook on each plate engages around the edge of the connector housing, creating a large area for power transmission between the two parts. The strength of the connection between the two parts is thus significantly improved.
  • the plates can be easily and quickly adapted to the desired coding combination by arranging the corresponding plates.
  • the locking elements in the transfer connector system known from EP-OS 128 307 each extend only over the width assigned to a pocket on the cable connector housing and consist of thin plates which are made of elastic material. If only one mechanical coding is required on each side of the cable connector housing, only two locking elements are provided for fastening the cable connector housing to the mating connector element. In many cases, the locking elements on both sides of the cable connector housing are not arranged symmetrically. If stronger external stresses act on the known transfer connector system, small relative movements between the multiple connector held by the cable housing and the mating connector element can occur in particular with only a few locking elements, which are not desirable because of the associated changes in the contact resistance. These difficulties are eliminated by the measures described in claim 1.
  • Another object of the invention is to be seen in improving a plug connection in such a way that the fitting elements on at least one connector part cannot be lost and, if necessary, can be brought into desired coding positions more than once.
  • At least one fitting element designed as a coding plate is elastically connected on one side to a plate which is part of the wall of the first or second connector or is connected to the wall, and that the coding plate is in a first Position does not protrude beyond the surface of the wall and can be detachably latched onto the wall in a second position in which it protrudes beyond the wall by approximately the depth of a recess on the other connector part which is open to produce the operative connection.
  • the coding plates are permanently connected to the plate and therefore cannot be lost. In order to bring a coding plate into a position selected for the unmistakable connection of two connector parts, it is only necessary to move it from its first end position to the second, in which it engages.
  • the locking position can be released and the coding plate can be returned to its first position if there was an error in the coding or if a new coding is required for other reasons.
  • the coding plates can be produced together with the plate, so that production is more economical.
  • the arrangement of the coding plates described above on a plug connector which contains the plates explained in claim 1 is particularly advantageous. However, it is also possible to use the coding plates in conjunction with other connectors.
  • the coding plates are each separated from the plates on three sides by a U-shaped slot and connected to the plates on one side via a zone with a small wall cross section.
  • the coding plates can be easily bent into the second end position.
  • the slot part is preferably formed at an angle to the plane of the plate at the front end of the respective coding plate.
  • At least one fitting element designed as a coding plate is connected to the surface of the plate so as to protrude beyond the surface thereof via predetermined breaking points.
  • the coding plates are removed at those points where the depressions on the other connector part are not open.
  • At least one fitting element designed as a coding plate is provided with locking lugs which protrude beyond the surface of the plate and can be latched into recesses in the plate.
  • This type of coding plate can be attached to the selected coding locations if necessary. It is particularly expedient if the coding plates are connected to the plate via floating-skin-like plastic parts. The coding plates are produced in one step with the plate.
  • predetermined breaking points running transversely to the length are provided on the plate of the locking elements at a spacing of a division which is assigned to the width of a pocket.
  • the plate can therefore be adapted to different lengths of cable connector housings by breaking the connection at the corresponding predetermined breaking point.
  • the division of the rectangular pockets is matched to the division of the springs or knives of the knife and female connectors.
  • the plate preferably contains recesses close to the cable-side end of the cable connector housing, into which an elastic bracket is inserted which encompasses the plates on both sides of the cable connector housing.
  • the elastic bracket forms an additional fastening for the plates and presses them onto the cable housing. In this way it is prevented that the connection between the plates and the cable connector housing is released even with very high external stresses.
  • the recess is provided on both sides of the predetermined breaking points. It is also expedient to provide plate parts which can be broken out by means of predetermined breaking points at the point which is provided for recesses.
  • the hooks projecting beyond the sockets are directed outwards. If necessary, the hooks can be pressed inwards to release the cable connector housing from the mating connector.
  • a rear wall plate 1 contains parallel rows of holes 2 which are arranged at a predetermined distance from one another. The distance corresponds to the division of pins 3 of a male connector 4.
  • the male connector 4 contains parallel rows of pins 3, one of which is designated in detail in FIG. 3. Holes 5 are provided at both ends of the male connector 4 and run parallel to the pins 3. By means of screws 6 inserted into the holes, the male connector 4 is fastened to the backplane 1. In the assembled state, the pins 3 protrude beyond the surface of the backplane 1.
  • Printed circuit boards 7, which carry electrical or electronic components, are inserted into the male connector 4, with female connectors 8, which are each fastened to the rear side of the male connector 4.
  • the ends of the pins 3 protruding beyond the surface of the backplane 1 are surrounded in parallel rows by a guide frame 9 for male connectors.
  • the guide frames 9 have holes 10 through which the pins 3 protrude.

  • latching elements of the cable housing half-shells which are not specified, engage in one another and bring about a firm connection between the cable housing half-shells 21, 22 and the female connector 15 or the wire guide element 17.
  • recesses 24 are provided for the passage of the cables 19.
  • the cable housing half-shells 22, 25 form a cable connector housing in the interconnected state, in which they enclose the female connector 15 and the cutting frame 17.
  • a number of male connectors 4 and guide frame 9 corresponding to the number of printed circuit board locations is fastened on the rear wall circuit board 1. For the sake of clarity, these parts are only shown once in FIG. 1. If necessary, the circuit boards 7 are inserted into the corresponding circuit board slots. Connections between pins 3 of different male connectors 4 can be produced via the plated-through holes 2, which are connected to conductor tracks of the backplane circuit board (not shown). A multilayer board may be used as the backplane.
  • Knife strips 28 can be fastened to the front end faces 27 if necessary if the number of connections on the rear end face 29 is not sufficient.
  • the male connector 28 is surrounded by a guide frame 30, the dimensions of which are adapted to the front plates 31 of printed circuit boards, which are usually fastened to rails 32.
  • the guide frame 30 and the male connector form a connector part.
  • the guide frame 30 contains recesses 35 at its ends 33, 34 Inclusion of inserts with which it is screwed to the rails 32.
