Definitions
- the present invention relates to an electrical connector rectangular of the type called insertion and extraction assisted, with a plug, a base and an insertion drawer and forced extraction of the plug.
- a plug for example the one described in document FR-A-2 424 643.
- the invention relates more particularly to connectors the base of which is provided with a grid intended to lock the contacts of the base when it is completely inserted on the base.
- a grid is designed to be able to take a pre-locking position, in which it remains hung on the base housing and however authorizes the placement or removal of contacts. It is important not to plug in the connector while the grid does not lock the contacts because that it is not fully inserted. Indeed, the contacts are then retained only elastically. The grid may remain partially depressed either due to an oversight in the pre-locking position, either because its displacement was arrested by a misplaced 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 corridors beyond of the oblique part which constitutes a ramp, may have a terminal portion substantially parallel to the direction drawer movement, so perpendicular to the direction of insertion, preventing vibrations from straining to separate the plug from the base by driving out the drawer.
- the connector shown in Figure 1 has a base 10 and a form 12.
- the terms "form” and “base” are used for convenience and in no way imply that the base constitutes the fixed element of the connector.
- the base carries a drawer 14 for insertion and extraction, in the shape of a stirrup, having a bottom 16 and two sides 17.
- the base 10 is intended to receive contacts formed by female contact terminals in the form of cage, while the plug 12 is intended to receive tab-shaped contacts. But this provision is not not at all exclusive.
- the base 10 includes a box 22 with rectangular section lying down. Two windows are cut in at least one of the short sides. They give way to the flanks 17 of drawer 14, which slides against the internal faces of large sides and is guided by an internal rim on the long sides. Thus, the drawer 14 can move in the direction F, but is retained in the direction of insertion and extraction, orthogonal to F.
- the base unit are provided with electrical contact receiving passages, 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 includes, in addition to the housing 22, a grid 32 locking contacts.
- This grid when it is fully engaged, prevents fingers from flexing elastically and release the contacts.
- a filling grid this function is described for example in the request for FR patent No. 94 15244 to which reference may be made. She has a median extension that engages between the fingers elastic of the two rows.
- Grid 32 may have the constitution shown partially in Figures 2,3 and 4. It is in one piece and can be viewed as having a support plate 52 against the bottom of the housing 22 and feet 54 intended for enter corridors in the corners of the box 22. Notches 56 are generally provided on the housing to engage in foot notches 54 and elastically retain the grid 32 either in a position of locking, either in a pre-locking position where it is retained on the case, but does not prohibit the replacement of contacts.
- the plate 52 is pierced with passages 58 intended for contact, aligned with the passage of the box 22.
- the plug 12 also has a box with rectangular section. Its external surface is mostly smooth. His part forward is intended to slide into a base cavity, 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 card, to lock the plug contacts.
- This grid may have the constitution described in the application patent filed on the same day as this 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 displacement of the drawer 14 in the direction of arrow F, insertion and locking the plug and cause the plug to be extracted by moving the drawer in the opposite direction.
- These means carried by the plug 12 and the drawer 14 can have the constitution described in the patent application above. They then have pawns protruding 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 coding To prevent the plug from being coupled in a inverted position, means, called polarization or coding, are generally provided. In the case shown on Figure 2, they have one or two internal ribs 40 plug housing, intended to engage in slots 42 of the housing 22 of the base. They can be supplemented by coding ribs engaging other slots 43 housing 22.
- the grid 32 is intended not only to lock the contacts, but also to prohibit the entry of the file when it is only partially engaged.
- the grid 32 has two foldable plates or flaps 60 (this number is not limiting) connected to feet respective 54 by thinner portions of the grid than the rest of the grid, intended to constitute hinges flexible 62.
- the grid is molded with the plates 60 in the position where they are shown in Figure 3, i.e. 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 a or several legs 64 belonging to the housing of the plug. In the case illustrated in FIG. 4, a single tab 64 is planned.
- the notches 56 are advantageously placed so that the grid 32 pre-locking position, i.e. shown in figure 5. In this case an attempt to sink of the plug is prohibited, since tab 64 comes in support against the plate 60. The deflection of this last is prohibited by its support on the edges of the slot 66.
- the grid 32 takes for example the position shown in FIG. 5B. It begins to free the path of leg 64. This last can then sink into slot 66, possibly by driving the grid 32 to its position of complete locking.
- Platelets 60 can be placed from each side of grid 32. Legs may be provided with each side of the plug, not just one side. In all in cases, the constituent parts of the connector are shaped simple enough that they can be made, made of plastic, in molds with a small number moving parts.
