Definitions

  • the present invention relates to a rectangular electrical connector of the type known as assisted insertion and extraction, having a plug, a base and a drawer for forced insertion and extraction of the plug.
  • Numerous connectors of this type are already known, for example the one described in document FR-A-2 424 643.
  • the invention relates more particularly to connectors whose base is provided with a grid intended to lock the contacts of the base when it is completely inserted on the base.
  • a grid is provided in order to be able to take a pre-locking position, in which it remains hooked on the base housing and however allows the establishment or removal of the contacts. It is important not to insert the connector when the grid does not lock the contacts because it is not fully inserted. Indeed, the contacts are then retained only elastically. However, the grid may remain partially depressed either because of an oversight in the pre-locking position, or because its movement has been stopped by a badly placed contact.
  • the invention aims in particular to eliminate the risk of coupling the plug and the base while the grid of the base is not in its fully inserted position.
  • the latter advantageously have an entry zone parallel to the direction of insertion.
  • the corridors, beyond the oblique part which constitutes a ramp, may have an end part substantially parallel to the direction of movement of the drawer, therefore perpendicular to the direction of insertion, preventing vibrations from tending to separate the plug from the base by driving out the drawer.
  • the connector shown in Figure 1 has a base 10 and a plug 12.
  • the terms "plug” and “base” are used for convenience and do not imply that the base constitutes the fixed element of the connector.
  • the base carries a stirrup-shaped drawer 14 for insertion and extraction, having a bottom 16 and two sides 17.
  • the base 10 is intended to receive contacts constituted by female contact terminals in the form of a cage, while the plug 12 is intended to receive contacts in the form of tongues. But this provision is by no means exclusive.
  • the base 10 comprises a housing 22 with an elongated rectangular section. Two windows are cut in at least one of the short sides. They allow passage to the sides 17 of the drawer 14, which slides against the internal faces of the long sides and is guided by an internal rim of the long sides. Thus, the slide 14 can move in the direction F, but is retained in the direction of insertion and extraction, orthogonal to F.
  • In the housing of the base are provided passages for receiving electrical contacts, arranged in two rows in the illustrated case.
  • the housing is cut so as to constitute elastic fingers intended to retain the contacts in their correct position.
  • the base comprises, in addition to the housing 22, a grid 32 locking contacts.
  • This grid when fully engaged, prevents the fingers from flexing elastically and releasing the contacts.
  • a grid fulfilling this function is described for example in patent application FR n ° 94 15244 to which reference may be made. It has a median extension which engages between the elastic fingers of the two rows.
  • the grid 32 can have the constitution shown partially in FIGS. 2, 3 and 4. It is in one piece and can be viewed as having a plate 52 bearing against the bottom of the housing 22 and feet 54 intended for '' engage in corridors formed in the corners of the housing 22. Notches 56 are generally provided on the housing to engage in foot notches 54 and resiliently retain the grid 32 either in a locking position or in a position of pre-locking where it is retained on the housing, but does not prevent the replacement of the contacts.
  • the plate 52 is pierced with passages 58 intended for contact, aligned with the passage of the housing 22.
  • the plug 12 also has a rectangular section housing. Its external surface is mostly smooth. Its front part is designed to slide into a cavity in the base, sliding against the short sides and against the internal edges of the base housing, which guide the drawer.
  • a grid is generally provided in the plug, to lock the contacts of the plug.
  • This grid may have the constitution described in the patent application filed on the same day as the present application for "Electrical connector with contact locking grid and drawer”.
  • the drawer 14 and the plug 12 include cooperating means intended to cause, in response to the movement of the drawer 14 in the direction of the arrow F, the insertion and locking of the plug and to cause the extraction of the plug by displacement in the opposite direction of the drawer.
  • These means carried by the plug 12 and the drawer 14 may have the constitution described in the patent application above. They then comprise pins projecting from the large faces of the plug housing, intended to engage in corridors 30 formed in the sides of the drawer 14. These corridors have an oblique part intended to constitute a cam ramp.
  • polarization or polarization means are generally provided.
  • they have one or two internal ribs 40 of the plug housing, intended to engage in slots 42 of the housing 22 of the base. They can be completed by coding ribs engaging in other slots 43 of the housing 22.
  • the grid 32 is intended not only to lock the contacts, but also to prevent entry of the plug when it is only partially engaged.
  • the grid 32 comprises two foldable plates or flaps 60 (this number not being limiting) connected to respective feet 54 by portions of the grid thinner than the rest of the grid, intended to constitute flexible hinges 62
  • the grid is molded with the plates 60 in the position where they are shown in FIG. 3, that is to say oriented parallel to the plate 52. Thus, they tend elastically to take the orientation shown in FIGS. 3, 4 and 5A, in which they are on the path of one or more tabs 64 belonging to the housing of the plug. In the case illustrated in Figure 4, a single tab 64 is provided.
  • the notches 56 are advantageously placed so that the pre-locking position of the grid 32 is that shown in Figure 5.
  • an attempt to sink the plug is prohibited, because the tab 64 abuts against the plate 60.
  • the bending of the latter is prohibited by its pressing on the edges of the slot 66.
  • the grid 32 takes for example the position shown in Figure 5B. It begins to release the path of the tab 64. The latter can then sink into the slot 66, possibly by driving the grid 32 to its fully locked position.
  • Plates 60 can be placed on each side of the grid 32. Tabs can be provided on each side of the plug and not on one side. In all cases, the component parts of the connector are of sufficiently simple shape that they can be manufactured, in plastic material, in molds having a small number of movable elements.
