Definitions

  • the invention relates to a cable connector for a plurality of stranded conductors and having the following features: a) a row of contact chambers lying side by side is formed in a housing; b) a contact element can be latched into the contact chamber; c) at least in some areas, each contact element has a sleeve-shaped design and has a crimp area for connecting a stranded conductor and a locking edge formed by a recess, pointing opposite to the direction of insertion, and d) the housing has a cross-section which extends transversely to the direction of insertion of the contact elements, Above the cutouts of the contact elements, a slot can be inserted into which a locking bar engaging behind the locking edges of the contact elements can be inserted.
  • Such line plugs are widely known, for example from DE-C-35 37 722 or from DE-U-86 08 199.
  • it makes sense to remove the contact elements that are sleeve-like or ring-shaped in some areas. bent in sheet form from sheet metal, to be bent upwards from a common base region.
  • the known plugs of this type are all designed so that the open side of the crimping area and the mentioned locking edge are formed on the same jacket side of the contact element, only slightly offset in the axial direction.
  • the object of the invention is to further develop a line connector of the type mentioned in the introduction such that, despite the plug attachment of the contact elements remaining the same and the locking also remaining the same, a reliable insulation between adjacent contact elements or line wires is ensured by means of a locking strip or an outer housing .
  • this object is achieved in that the cutouts or the locking edges on the one hand and the open sides of the crimping areas on the other are provided on opposite jacket sides of the contact elements and that the crimping sections of the inserted contact elements each face a closed housing wall lie.
  • the crimping areas are thus facing away from the locking areas of the contact elements, so that the crimping area on the side of the locking edge and the housing slot has a more or less closed sheet metal jacket and, on the other hand, a closed side with its open side Housing wall is turned. Even if a stranded wire is spread open at its free end and the free ends of the individual conductors are uncontrolled to the outside, they cannot cause a short circuit, since they face a closed wall area of the insulating material housing and in any case with the one inserted transversely The locking bar does not come into contact.
  • FIGS. 1 and 2 show a first embodiment of a line connector according to the invention in two partial sectional views
  • FIG. 3 shows a further embodiment of a line connector in a sectional view corresponding to FIG. 1,
  • Figures 4 to 6 a contact spring for the cable connector of Figure 1 in three views
  • the line connector shown in FIGS. 1 and 2 has a housing 1 which has two rows of contact chambers 11 one above the other.
  • the individual contact chambers with an essentially rectangular cross section are separated from one another by a continuous horizontal wall 12 and by individual vertical walls 13.
  • the contact chambers are likewise closed to the outside, that is to the top or to the bottom, by walls 1A, but these walls have interruptions, which will be described in detail later.
  • a contact element 2 is inserted in the longitudinal direction in the individual contact chambers.
  • a latching lance AI is formed on each contact element 2 in the front area and is latched in a window 15 of the housing 1.
  • Each contact element also has a locking edge 22 which is formed on the side of the contact element facing the outer wall 1A of the housing.
  • the housing has a slot 16 into which a locking bar 31 can be inserted from the side, that is to say transversely to the longitudinal direction of the contact elements 2.
  • the locking bar 31 is part of an overhousing 3 which, in a manner known per se, comprises the entire housing with the two rows of contact chambers and contact elements lying one above the other.
  • the locking bar 31 with its end edge 32 offers a A impact for the mentioned locking edge 22 of the contact elements and thus additionally secures them against an undesired pulling out of the housing.
  • the contact spring 2 has at one end (in FIGS. 1 and 2 at the right end) a crimping area 29 with crimping tabs 23 and securing tabs 2A.
  • a wire 5 of a ribbon cable designed as an insulated strand is inserted into this crimping area.
  • the wire with the insulation 51 is securely clamped with the securing layers 2A, while the free end of the wire 5 is stripped, so that the individual conductors 52 lie bare and are contacted by the bent crimp tabs 23.
  • the free ends 52a of the individual conductors can protrude beyond the crimping tabs 23 without the risk of a short circuit with an adjacent stranded conductor, since the open side of the crimping area in the housing 1 faces inwards towards the wall 12, so that the free space, in which the ends 52a of the stranded conductor emerge, is insulated from three sides by the walls 12 and 13.
  • the free ends 52a of the stranded conductors cannot be dragged into an adjacent contact chamber by the sliding movement of the locking bar 31, since the slot 16 of the housing and the locking edge 22 of the contact elements are on the opposite side of the contact elements 2 facing away from the crimping area.
  • the area freed from the contact element in the form of a cover tab 25 in the approximately sleeve-shaped contact element 2 is cranked inward and thus additionally prevents the ends of the wire 52a from spreading out into the displacement area of the locking bar 31.
  • FIG. 3 shows a somewhat modified embodiment compared to FIG. 1.
  • a housing 101 is formed with two rows of contact chambers 111 such that the contact chambers each have walls 112 closed to the outside and walls 11A perforated inwards. In these walls are 11A each window 115 for receiving the locking lances AI and
  • Slits 116 are formed for inserting a locking bar 131.
  • this locking bar 131 is designed as an individual part, that is to say it is not part of an overhang.
  • the contact elements 102 are configured in exactly the same way as the contact elements 2 in FIG. 1; they are only inserted rotated by 180 ° with respect to this figure.
  • contact elements in FIG. 1, 2 or 3 each consist of a contact spring 21 and an over-spring A.
  • the contact spring 21 shown in FIGS. A, 5 and 6 in three different views is bent from sheet metal in a substantially channel-shaped manner.
  • the crimp tabs 23 and the securing tabs 2A, which have already been mentioned, are formed at the connection end.
  • the securing edge 22 is punched out, the cut-out tab 25 being bent down as a cover flap.
  • the contact end opposite the connection end is shaped into plug springs 26 (not shown in FIG. 6).
  • the over-spring A shown in FIGS. 7 to 9 in the same views corresponding to the representation of the contact springs in FIGS. A to 6 is bent into a plug-in sleeve with an approximately rectangular cross section and crimped onto the contact area of the contact spring.
  • the crimping tabs A2, which grip over the central region 27 of the contact spring 21, serve this purpose. From this spring A, the already mentioned locking lance AI is bent upwards, which is provided with a bead A3 for stiffening.

Abstract

La fiche comporte, dans les espaces de contact juxtaposés d'un boîtier en matériau isolant (1), des éléments de contact comprenant chacun une zone de sertissage pour la connexion de conducteurs torsadés. Le boîtier comporte également, pour chaque élément de contact, une fente (16) destinée à recevoir une barrette de serrage (31) qui agit avec l'arête de serrage (22) de chaque élément de contact. Pour éviter que les extrémités écartées des conducteurs torsadés soient entraînées dans les espaces de contact voisins lorsqu'on enfonce la barrette de serrage (31) transversalement par rapport à l'axe longitudinal des éléments de contact et pour prévenir ainsi l'établissement d'un court-circuit, chaque zone de sertissage est placée sur un côté de l'enveloppe, opposé à l'arête de serrage, de l'élément de contact (2) réalisé en partie sous forme de douille.
