Definitions

  • the subject of the present invention is a connector of polygonal type, in particular rectangular, having a housing in which is positioned an insulating central body having electrical contact elements.
  • a polygonal electrical connector for example a connector meeting the SCSI-2 standard, rectangular generally has a rigid housing, particularly a metal body, ensuring the rigidity of the connector and in which are housed on the one hand the insulating central body comprising several rows of parallel contact elements, and on the other hand, in the case of female contact connectors, a metal shield surrounding said insulating body in its part which must receive the opposite male contact connector.
  • the central insulating body is fixed to the metallic body constituting the housing can be made by wings protruding from the insulating body on the rear of the connector and fixed to the metallic body.
  • This fixing system has the disadvantage of not being able to be used in the case of connectors with miniature straight contacts because this space is too great.
  • this system protruding from the connector is vulnerable to the manipulations in particular necessary for the manufacturing stages.
  • the subject of the present invention is a fixing system which on the one hand can be used both for connectors having male or female contacts, whether they are of the straight or angled type and on the other hand, has dimensions very reduced while ensuring precise mechanical positioning of the contact carrier insulating body with respect to the connector housing.
  • the invention thus relates to a polygonal type connector having a housing in which is positioned an insulating central body having electrical contact elements, said positioning being obtained, by cooperation, between at least one beam element and at least one lug, the insulating central body abutting with respect to the housing, characterized in that the main axis of said beam element runs along a part of a polygonal contour common to the housing and to the insulating central body.
  • This fixing system can also make it possible to produce an identical insulating body for the connectors with straight pins and bent pins.
  • Said beam element is advantageously disposed at a longitudinal end of the insulating central body and said lug is advantageously disposed on an internal transverse face of the housing.
  • the connector according to the invention comprises two beam elements each arranged at a longitudinal end of the insulating body and two lugs each arranged on an internal transverse face of the housing.
  • said lug is adjacent to a middle part of the corresponding beam element. This makes it possible to make the best use of the elasticity of the beam when it passes over the lug.
  • the beam element can be inclined relative to the direction of insertion of the insulating central body so as to facilitate the sliding of the beam element along the corresponding lug.
  • Said middle part is advantageously located outside of an area where the insulating central body abuts in the housing, said lug extending backwards by a groove.
  • said beam element comprises a central part, the ends of which each extend by an elastic arm substantially perpendicular to said central part. A higher elasticity is thus obtained during the insertion of the insulating central body while maintaining its precise positioning in the housing.
  • Said beam element advantageously forms an integral part of the insulating central body.
  • a shielding cover can be housed between the insulating central body and the housing.
  • the shielding cover can be fixed on the insulating central body thanks to the cooperation of two upper and lower longitudinal edges and lugs arranged on two upper and lower longitudinal edges of the insulating central body. These pins make it possible to preposition the shielding cover on the insulating central body, the shielding cover then being locked in position between the insulating central body and the housing.
  • the housing may include notches intended to cooperate with the locking arms of a connection element cooperating electrically with said connector.
  • a rectangular type connector has a central insulating body having a rear face 11 into which open, for example, connection elements of the female type not shown in this figure (see fig. 3b; rep. 65).
  • the rear face 11 has upper and lower longitudinal edges 18 and lateral edges 17.
  • the rear face 11 is extended by a front face 12 whose outline is inscribed inside that of the rear face 11 and which has upper and lower longitudinal edges 19 substantially parallel to the upper and lower edges 18 as well as lateral edges 14 not perpendicular to the edges 19.
  • the longitudinal ends 17 of the insulating central body 1 have a beam element 41 defined by its thickness e 1 parallel to the longitudinal direction of the rear face 11, its length L perpendicular to this direction in the plane of the rear face 11, and its width 1 perpendicular to the above two directions.
  • the beam 41 can advantageously be extended by two elastic arms 42 and 43 which are perpendicular to it and which have a length d defined by two clearances 44 and 45, and a thickness e 2 .
  • the housing 2 is preferably made of a conductive material, for example of a zinc-based alloy known under the trade name "ZAMAC".
  • the metal body forming a housing 2 has a rear face carrying two upper and lower longitudinal edges respectively 28 and 29 and two trihedra composed of orthogonal elements referenced 22, 24 and 25 allowing, in particular by means of openings 24 'and 25', the fixing of the housing 2 on a support such as a chassis or a printed circuit.
  • Each trihedron comprises on the one hand a vertical element 25 extending the upper edge 28 towards the lower edge 29, the lower edge 29, and on the other hand, an element 22 also vertical but perpendicular to the upper edge 28, and connecting to element 25.
  • the lower edge 29 extends between the two elements 22.
  • the trihedron is completed by a horizontal element 24. Fastening openings 24 'and 25' are arranged in the trihedron elements 24 and 25 .
  • the internal face 22 of the trihedral part 22 has substantially at mid-height a lug 50 having successively an inclined profile 51, a region 52 parallel to the element 22 and a region forming a stop 53 substantially perpendicular to the plane of the element 22 Finally, each of the elements 22 can be extended forward by a locking element comprising an arm and a lug 27.
  • the shielding cover 3 has a rear portion having longitudinal edges 38 arranged so as to be able to engage with pre-positioning lugs 15 disposed in the middle of the longitudinal edges 18 of the insulating central body 1.
  • the longitudinal edges 38 are connected by vertical portions 35, the assembly defining, with upper and lower edges 37, an opening 36 which engages in the front face 12 until it comes into abutment on the rear plane 13 of the front face 11.
  • the insulating central body 1 can be mounted on the housing 2 with or without the interposition of the shielding cover 3.
  • the middle part 46 of the beam 41 is gradually pushed back by the profile 51 of the lug 50, after what the beam 41 returns to its initial position to lock the central insulating body 1 in the housing 2. It will be noted (see Figure 3c) that this insertion can be facilitated by tilting the beam 41 at an angle relative to the internal face of the element 22 of the housing 2.
  • the beam 41 is thus susceptible to two successive types of deformation during insertion.
  • the lug 50 deforms it in a direction perpendicular to the internal face of the element 22 and this deformation is absorbed by the central part 41 and by the arms 42 and 43. This makes it possible to reduce the stresses and allows good elasticity despite reduced dimensions. This function is fulfilled optimally when the lug 50 is positioned in the immediate vicinity of the central part 46 of the beam 41.
  • the length L, the width 1 and the thickness e of the beam 41 allow its flexibility to be adjusted.
  • the bending of the elastic arms 42 and 43, the elasticity of which is defined by their length d, their width 1 and their thickness e 2 allows the beam 41 to move perpendicularly to its plane longitudinal axis.
  • the central insulating body 1 may include a crimping means (not shown) disposed on at least one longitudinal edge 18.
  • FIGS. 3a and 3b show a complete connection assembly using a male connector of the elbow contact type in which male elements 61 bent at 62 are housed.
