Definitions

  • the invention relates to a connector of the bent pin type, possibly force-fit ("press-fit”) on a printed circuit board.
  • such a connector comprises an insulating body carrying a series of bent pins whose proximal branches (relative to the card) are essentially perpendicular to the card and can have a profile allowing the force fitting in a metallized hole of the circuit. printed, and whose distal branches (relative to the card) are essentially parallel to the card and are integral with an active part disposed in the insulating body and configured as a member, male or female, of connection.
  • connection members carried by the distal branches of the pins are intended to produce essentially removable electrical connections, for example with a connector of the rectangular type.
  • the mounting on the card of a force-fit connector is generally carried out by direct pressing on the pins in their bent region, in order to cause the latter to sink into the metallized holes opposite.
  • the nominal insertion force is high, of the order of 50 N per spike.
  • This operation has the disadvantage of requiring a specific tool for each connector, in order to press simultaneously and uniformly on each of the pins of the connector.
  • EP-A-0 335 160 (HARTING ELEKTRONIK GmbH) relates to a connector comprising a rear insulating body provided with support blocks. These blocks have no contact holding face in a horizontal direction.
  • the proposed solution does not allow the maintenance of all rows. The push must be carried out exactly on the top of the row of legs: a specific tool is also provided for this purpose.
  • the invention proposes to remedy this drawback, thanks to a connector whose insulating body has a specific geometry which allows simultaneous pressing on all the contacts when the connector is plugged into the printed circuit board.
  • the plug-in connector on a printed circuit board comprising metallized holes has a front part comprising a first insulating body in which are arranged connection elements called bent pins having a distal end configured in male or female connection contact, a distal branch intended to be disposed substantially parallel to such a card, an elbow connecting the distal branch to the proximal branch of the pin, essentially perpendicular to the distal branch, a proximal end having a profile allowing racking in one of said metallized holes, characterized in that that it comprises a second insulating body having slots superposed two by two intended to receive bent pins located two by two in the same plane perpendicular to such a card, each slot having a first face essentially parallel to the distal branch and intended to allow a p pushed on the distal branches during the racking of said proximal ends in the card and said slots have a second face substantially perpendicular to the first face to maintain in position the proximal branches in the direction of insertion of the connection members
  • Said slots can have a third and a fourth bearing faces for position the proximal branches in the direction of insertion of the connecting members.
  • the slots belonging to different rows of contacts have different lengths parallel and perpendicular to the card.
  • a connector according to the invention is characterized in that each slot has two parts, namely on the one hand a first part forming an insertion slot opening onto an upper face of the second insulating body and having a fifth face essentially perpendicular to the card to receive a proximal branch of a said bent pin introduced vertically by said upper face by its said proximal end as well as a sixth face essentially parallel to the card to form a stop for the distal branch of said pin and on the other hand a second part forming a holding slot and having at least said first face, so that the first face cooperates with the distal branch by horizontal introduction.
  • the distance vertically separating the first face and the sixth face is advantageously substantially greater than the height h of a distal branch of a bent pin.
  • the insulating body may have studs of calibrated height in the vicinity of said profiles. This ensures a calibration of the fitting depth in the case of a force fit ("press-fit") and the catching up of manufacturing tolerances and compaction (elastic recoil) of the rear insulation during insertion so as to obtain a complete insertion of the pins.
  • press-fit force fit
  • compaction elastic recoil
  • Locking arms can be arranged at two opposite longitudinal ends of the second insulating body.
  • the first insulating body can be fixed in a housing, the second insulating body being mounted on the housing by cooperation between the locking arms and notches arranged at two opposite longitudinal ends of said housing.
  • a rectangular type connector 5 has an insulating central block 10 having a rear part 11 and a front part 32 whose outline is inscribed inside that of the rear part 11.
  • Male or female contacts of connection 70 forming part of bent pins 61 are arranged in the block 10.
  • the longitudinal ends 17 of the insulating central block 10 have a beam element 41 extended by two elastic arms 42 and 43 which are perpendicular thereto.
  • the beam element 41 is locked by a lug 50 having an inclined profile 51 and a region 53 forming a stop.
  • a shielding cover 3 surrounds, at 34, the front part 32 of the insulating block 10 and frames, at 38, the upper and lower portions of the rear part 11.
  • the metal body forming a casing 1 has a rear face carrying two upper and lower longitudinal edges 28 and 29 respectively and two compound triedes orthogonal elements referenced 22, 24 and 25 allowing, in particular through openings 24 ', the fixing of the housing 2 on a support such as a chassis or a printed circuit.
  • Each tried comprises on the one hand a vertical element 25 extending from the upper edge 28 towards the lower edge 29, and on the other hand, an element 22 also vertical but perpendicular to the upper edge 28 and connecting to the element 25.
  • the lower edge 29 extends between the two elements 22.
  • the triede is completed by a horizontal element 24.
  • the elements 22 have notches 23 intended to cooperate with the ends 67 of the elastic arms 66 of an insulating body 60 and which are arranged at the longitudinal ends of the insulating body 60.
  • the front part 32 has through openings 16 in which the contacts 70 are housed, which are extended towards the rear by bent pins 61.
  • the rear part of the force-fit plug-in connector 4 has an insulating central body 60 in which are housed the pins 61 bent at 90 ° at 62 and comprising a proximal branch 65 (relative to the card) extended by profiles 63 which can be of the type allowing press-fit into a metallized hole in a printed circuit 80.
  • the distal branch 64 adjoins a bearing surface 71 of a groove 90.
  • This bearing surface 71 is essentially parallel to the card 80 and thus constitutes a bearing surface allowing insertion profiles 63, in particular a forced insertion.
  • the proximal branches 65 (relative to the card 80) are in turn surrounded by three bearing surfaces 72, 73, 74 of the slot. These surfaces 72, 73, 74 have a U-shaped section and surround the proximal branches 65 in the direction profiles 63 and perpendicularly on either side of the insertion direction (see box in Figure 3).
  • the slots 90 have unequal lengths both perpendicularly to the card and parallel to it, and that two pins of different lengths are located in the same vertical plane (cutting plane B-B).
  • the assembly of a connector is carried out from an insulating body 10 mounted in a case 1 which is essentially conductive.
  • the geometry of the central body 60 having the slots 90 allows first of all by a vertical movement (FIG. 1A) to present the distal end of the bent spikes 61 by the upper face 81 of the insulating body 60 (insertion by displacement of the insulating body 60 according to arrow F 1 ).
  • the proximal branches 65 slide along the vertical faces 76 forming part of insertion slots 91, except for the row of pins located in the immediate vicinity of the front part 11 and which adjoin the front face 79 of the body insulator 60.
  • the vertical faces 76 are slightly inclined to guide the profiles 63.
  • the distal branches 64 come into practically abutment on horizontal faces 77 (except for the row of pins 61 closest to the front part 11), and their lateral movement is limited by the vertical edges 82 framing the horizontal faces 77.
  • the horizontal faces 77, the vertical edges 82 and the vertical faces 76 thus define insertion slots 91 of bent pins 61.
  • the second step implements a horizontal relative displacement (displacement along arrow F 2 of FIG. 1B) until the ends 67 of the elastic arms 66 snap into place in the notches 23 to arrange the bent pins 61 in positioning slots 90 ( position shown in Figure 1C).
  • the proximal branches 65 are in the immediate vicinity of the vertical edges 72, and the proximal branches are in abutment against horizontal edges 71, and their lateral movement is limited by the vertical edges 73 and 74 framing the faces 71 and 72 (see box of Figure 3).
  • the elbows 62 are located opposite cut sides 75 connecting the faces 71 and 72.
  • the horizontal faces 71, the vertical faces 72 and the vertical edges 73 and 74 thus define positioning slots 90 of the bent pins 61, which communicate with the aforementioned introduction slots 91.
  • the distance which vertically separates the horizontal faces 71 and 77 corresponding to the bent spikes 61 situated in the same plane is substantially greater than the height h of the proximal branches 64.
  • the horizontal faces 71 serve as a bearing face and the insulating central body 60 serves as an insertion piece, the insertion press coming to bear on the upper face 81 of the body 60. There is therefore no need to provide any tools or additional part.
  • the insulating body 60 ensures precise relative positioning between the ends 63 during their insertion.
  • Studs of calibrated height 81, (or washing feet) arranged at the lower part of the insulating block 80 ensure a calibration of the fitting depth of the plug-in profile with force 63 and the catching up of manufacturing tolerances.
  • the device described above is more particularly usable in a connector as described in application FR 91-15295 filed on December 10, 1991 by the Applicant (FR-A-2 684 810, published on June 11, 1993), namely a force-fit connector comprising an insulating body having a generally square-shaped part having a mounting wing and a connecting wing, and a pressure block part comprising bearing surfaces bearing against the distal branches of the pins.
