Definitions

  • 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 make the contact elements which are sleeve-shaped or channel-shaped in some areas Sheet metal are bent to bend upwards from a common base area.
  • the known plugs of this type are all designed so that the open side of the crimp 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 such a way that, despite the plug connection of the contact elements remaining the same and the locking also remaining constant by means of a locking strip or an outer housing, reliable insulation between adjacent contact elements or line wires is ensured.
  • this object is achieved in that the recesses or the locking edges on the one hand and the open sides of the crimping areas on the other are each provided on mutually opposite jacket sides of the contact elements and in that the crimping sections of the inserted contact elements are each opposite a closed housing wall.
  • 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, its open side faces a closed housing wall. 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 because they face a closed wall area of the insulating material housing and in any case do not come into contact with the transversely inserted locking strip.
  • the line connector shown in FIGS. 1 and 2 has a housing 1 which has two rows of contact chambers 11 lying 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 also closed by walls 14 towards the outside, that is to say towards the top or bottom, but these walls have interruptions, which will be described in detail later.
  • a contact element 2 is inserted into the individual contact chambers in the longitudinal direction.
  • a latching lance 41 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 jacket side of the contact element facing the outer wall 14 of the housing.
  • the housing has a slot 16 in 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 offers a stop with its end edge 32 for the mentioned locking edge 22 of the contact elements and thus additionally secures them against unwanted pulling out of the housing.
  • the contact spring 2 has at one end (in FIGS. 1 and 2 at the right end) a crimp area 29 with crimp tabs 23 and securing tabs 24.
  • a wire 5 of a ribbon cable designed as an insulated strand is inserted.
  • the wire with the insulation 51 is clamped with the securing tabs 24, 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 located on the opposite jacket side of the contact elements 2 facing away from the crimping area.
  • the area punched out by 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 strand ends 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 in such a way that the contact chambers each have walls 112 closed to the outside and walls 114 perforated inwards. 114 are in these walls each window 115 for receiving the locking lances 41 and slots 116 for inserting a locking bar 131 formed.
  • This locking bar 131 is formed in this example as a single part, so not part of an outer housing.
  • 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 4.
  • the contact spring 21 shown in FIGS. 4, 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 24 are formed at the connection end.
  • the locking 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 4 shown in FIGS. 7 to 9 in the same views corresponding to the representation of the contact springs in FIGS. 4 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 42 which engage over the central region 27 of the contact spring 21, serve this purpose. From this over-spring 4, the locking lance 41 already mentioned is bent upwards, which is provided with a bead 43 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.
