A connector mechanism for electrically connecting two structures 22, 24 carrying conducting lines 26, comprises fixed contacts 28 on one of the structures and floating contacts 30 on the other of the structures, the floating contacts being free to move towards and away from the fixed contacts and across the fixed contacts as independent motions, under the control of a common actuator 50, 52, 54, each floating contact being an electrically integral part, carried by the actuator, of a flexible conductive film 34. The provision of a shroud 46 on the fixed contact structure carrying markings 48A, 48B registered with the fixed contacts 28 and engaging the actuator provides coarse location, while the flexibility of the web and the mounting of the floating contacts on a resilient pad 38 on a carriage 50 provided with cam followers 54 riding on a multi-throw linear cam 52, together comprising the actuator permits independent locating and wiping motions, independently of each other and at selected pressures, including zero pressure on insertion, making the connector mechanism an effective ZIF connector. |

DETAILED DESCRIPTION OF THE EMBODIMENTS Returning to the embodiments illustrated in FIGS.
1 to 5 of the drawings and considering them in greater detail, structure 22 is a printed circuit card, of which only a corner is shown, and has conducting lines 26 on both faces thereof, each set of conducting lines ending in a 4.
times.
N array of contact dimples 28, fixed relative to the card.
The conducting lines 26 are only hinted at, rather than being shown accurately in FIGS.
1 and 2 and no attempt has been made to show their connection to the contact dimples 28.
In any case, much of the conducting line configuration will be buried in most applications.
Shroud 46 overhangs the contact dimple array and is formed of two substantially equal mutually perpendicular extents 46A and 46B.
Extent 46A is perpendicular to the face of the card from which it extends and parallel to the card edge and the N-dimension of the contact array.
Extent 46B extends parallel to the card face beyond the card edge and has a T-cross-section groove 48A let into its inner surface facing the contact array.
Extent 46B has notches 46B let into its exposed edge.
Selected surfaces of the groove and notches are accurately registered with the contact array and act as locating markings.
Linear cam 52 has an integral longitudinal rail 52A which fits into the groove 48A in the shroud and aligns the pass direction of the linear cam relative to the fixed contact array in the ZZ direction.
The cam 52 has multiple pairs of camming surfaces providing throws in both the XX and the YY directions but these are arranged, relative to the cam followers 54A and 54B, so that the currently effective throw is either entirely in the XX direction or entirely in the YY direction.
The effect of these throws for a single pass of the linear cam is illustrated in FIG.
3.
In addition to fitting in the groove 48A in the shroud, the linear cam 52 also fits into the carriage 50 which is a generally rectangular channel, open at the ends for access in the ZZ direction and having walls extending in the XX direction
