Definitions

  • the invention relates to a connector for connecting a multi-core electrical flat cable to other circuit elements, consisting of two flat shell shells that can be fastened to one another, a multi-part insulating body for receiving, holding and guiding a plurality of contact pieces arranged in two parallel rows, the insulating body being one upper and one to it has parallel lower surface, is clamped between the frontally open clamping shell parts and each contact piece has an upper connection part which extends at right angles from the upper surface of the insulating body to a common distance from it, which upper connection parts have a uniform first distance from one another, and one lower connecting part, which extends at right angles to said lower surface to a common distance from it beyond it, which connecting parts have a uniform second distance from each other, the si ch differs from the first distance, the upper and lower connection parts of each contact piece being connected to one another by a deformable, flat band.
  • Such connectors are known for example from EP-A-38 338.
  • the insulating body is formed there from a carrier and a trough-shaped insulating body.
  • To mount the contact pieces on the carrier it is necessary to keep the carrier clear, since the contact pieces must be inserted into the carrier on both sides. Then the carrier must be inserted into the trough-shaped insulating body and connected to it in a latching manner, which requires additional work and the arrangement of additional fastening clips. The material and manufacturing effort required for this connector is considerable.
  • the invention has for its object to provide a connector of the type described, which allows for easier assembly with less material and also allows the bending of the flat cable connected to the connector in such a way that one or both sides flat cable led out on the top can be bent so that it lies within the alignment of the insulating material body, so that conventional covers can be pushed over.
  • the invention proposes that the ⁇ so) ierstoff Archives consists of two half-shells, the parting line between the two rows of contact pieces, that the bottom surface of the bottom of the half-shells is perforated accordingly for the passage of the lower connecting parts of the contact pieces that the receptacle for the upper connecting parts is formed by adapted recesses of the shell part holding the contact piece and open to the parting line and to the upper surface, and a clamping part of the other half-shell part urging the connecting part towards the recess wall, the rows of contacts being arranged offset parallel to one another, so that in each case a clamping part of one shell part faces an upper connection part of the contact piece of the other shell part when the shell parts are joined together so that the shell parts between the inner end parts of the connection parts of each contact piece have massive, shell part-specific supports a and that the receptacles for the connecting parts of each contact piece are connected by a connecting channel which is also open to the parting plane for the band connecting the connecting parts.
  • the design of the insulating body from two half-shells significantly reduces the cost of materials.
  • the assembly is enriched in that the half-shells of the insulating body can be placed on one side on a base so that the contact pieces can be inserted mechanically or manually in this position.
  • the contact pieces To insert the contact pieces, it is necessary that these are first inserted with their lower connecting part, usually a plug part or a sleeve part, into the corresponding perforation in the bottom of the half-shell, after which they can be pivoted towards the side wall of the half-shell in order to be inserted into the corresponding recesses and recordings to be inserted.
  • the contact pieces used in this way are locked in such a way that the two shell halves are joined together with openings facing one another, with the clamping parts locking the assembly position.
  • the molded on the half-shell parts prevents the upper connection parts, for example knife contacts, from being pressed into the interior of the insulating material body when the corresponding ribbon cable is inserted and pressed in, which would prevent proper contact.
  • the supports prevent the lower An from being pressed in circuit parts when establishing the plug connection with an appropriate electrical device, so that reliable contact is also ensured here.
  • the formation of the insulating body from two half-shells gives the possibility of moving the contact pieces relatively far inwards so that they are at a distance from the contours of the insulating body, which enables the bending of a connected ribbon cable in such a way that the ribbon cable within the escape of the insulating body is arranged.
  • the clamping parts have a width which corresponds to only a part of the width of the upper connecting parts, in particular less than a third of the width.
  • the upper connecting parts are at a distance from the outer wall of the half-shell facing away from the joint of the half-shells and running parallel to the joint, which corresponds at least to the thickness of the flat cable.
  • the connected ribbon cable does not protrude beyond the contours of the connector, that the upper surface of the insulating body can be covered in a manner known per se by means of a clamping bracket which can be locked on the insulating material body, the clamping bracket having retracted side edges whose entry into the width corresponds approximately to the distance of the upper connection parts from the outer wall of the insulating body.
  • a further material saving is achieved in that the upper clamping shell part is formed without a middle wall, the two end caps thus formed having the catches which can be locked with the insulating material body and the passage openings for the fastening means for holding on the lower clamping shell part.
  • the half-shells forming the insulating material body can be locked and / or glued and / or welded at their lower and lateral edge parts located in the parting line.
  • the connector for connecting a multi-core, electrical flat cable consists essentially of two, preferably metallic, clamping shell parts 1, 2 which can be fastened to one another, for example by means of screws or rivets, a multi-part insulating material body 3, 4 for receiving, holding and guiding a large number of contact pieces arranged in two parallel rows 5 and a clamping bracket 6 designed as a lid.
  • the insulating material body 3 has an upper and a lower surface parallel to it and is clamped between the frontally open clamping shell parts 1, 2.
  • Each contact piece 5 has an upper connection part 51 which extends at right angles from the upper surface of the insulating material body 3 to a common distance from it, the upper connection parts 51 being at a uniform first distance from one another.
  • each contact piece 5 has a lower connection part 52, which extends at right angles to the lower surface of the insulating body 3 to a common distance from it beyond, these connection parts also having a uniform, but second distance from each other, which differs from that first distance differs.
  • the upper and lower connecting parts 51 and 52 of each contact piece 5 are connected to one another by a deformable flat band 53.
  • a further insulating material part 4 is provided, which already serves to protect these parts when the plug connection is made. If the lower connection parts 52 are designed as father parts, the insulating part 4 is unnecessary.
  • the contact pieces are produced in one piece by means of a stamping or bending process, the contact pieces for a row being initially punched and bent in a coherent manner from a sheet metal strip, the different spacings of the upper and lower connecting parts is generated. This continuous row of contacts is then inserted into the insulating material body 3, as will be described later. The separation of the Who k material connection between the contacts of a series after mounting in the insulating body.
  • the insulating body 3 consists of two half-shells 31, 32, the parting line of which lies between the two rows of contact pieces.
  • the lower surface of the insulating body is formed by the bottoms of the half-shells 31, 32, which have perforations for the passage of the lower connection parts 52 of the contact pieces 5.
  • the receptacle for the upper connecting parts 51 is formed by adapted recesses of the shell part 31 or 32 holding the respective contact piece 5 and open to the parting line and to the upper surface, and a clamping part 33 of the other half-shell part 32 or 31 pushing the connecting part 51 to the recess wall .
  • the rows of contact pieces are offset parallel to each other, so that a clamping part 33 of the one shell part 31 or 32 an upper connection part 51 of the contact piece 5 of the other shell part 32 or 31 together face-to-face shell parts.
  • the shell parts 31, 32 have between the inner end parts of the connection parts 51 and 52 of each contact piece 5 massive, part of the shell parts, which prevent undesired insertion of the connection parts when inserting the ribbon cable or when establishing the plug connection.
  • the receptacles for the connecting parts 51 and 52 of each contact piece 5 are each connected by a connecting channel open to the parting plane for the band 53 connecting the connecting parts 51, 52. These connecting channels are shaped differently according to the different bending shape of the band 33.
  • the clamping parts 33 are only as wide as approximately half, preferably less than one third, of the width of the upper connecting parts 51 of the contact pieces 5. This can be seen particularly clearly in FIG. 3. Furthermore, the upper connecting parts 51 are spaced apart from the outer wall of the half-shells facing away from the parting line of the half-shells 31, 32 and parallel to the parting line by at least the thickness of the flat cable to be connected to the connecting parts 51. In this way, it is possible to bend the flat cable upwards after the connection to the connecting parts 51 has taken place in such a way that the contours of the flat cable lie within the contours of the insulating material housing 3.
  • the clamping bracket 6 which is designed as a cover and which covers the upper surface of the insulating body 3 and presses the inserted flat cable into the connecting parts 51.
  • the cover 6 is provided with retracted side edges, as can be clearly seen from FIG. 1.
  • the width of the indentation corresponds approximately to the distance of the upper connecting parts 51 from the outer wall of the insulating body 3.
  • the cover 6 is fastened to the insulating body 3 by means of catches 34, 35 and corresponding grooves in the cover part 6, which cannot be seen from the drawing.
  • the latching nose 34 serves for pre-locking, while the locking lugs 35 secure the final locking position.
  • the upper clamping shell part 2 is formed without a middle wall, as can be seen from FIG. 1.
  • the two end caps formed in this way have catches 21 which can be locked with the insulating material body 3 and overlap corresponding projections 36 of the insulating material body 3.
  • the half-shells 31, 32 are provided on their lower and lateral edge parts in the parting line with mother and father parts to form a plug-in or latching connection. In addition or alternatively, these parts can also be glued or welded to one another, for example ultrasonically welded.
  • FIG. 2 it can be seen particularly clearly how the lower and upper connecting parts 51 and 52 are held by molded supports of the half-shell 31 for absorbing pressure forces and for securing against displacement.
  • the arrangement and design of the clamping parts 33 with their curved shape of their front edge can also be clearly seen from this figure.
  • FIG. 3 it can be seen that the contact pieces of the contact rows running parallel to one another are arranged offset from one another and that the clamping parts 33 engage in a tooth-like manner when the two shell halves 31, 32 are joined together.
  • the illustration in FIG. 3 corresponds to the joining together of the half shells shortly before they are brought together completely.
