Abstract
Abstract A connector including a female housing having a plurality of male terminals and a male housing having a plurality of female terminals. The female housing further includes at least two guide rails connected to each other and provided with an axis hole. A pair of sliders are each slidably engageable with the guide rails. Each slider has an upwardly projecting pin and a cam follower projecting downwardly. A pair of longitudinally aligned slots are formed between the two guide rails and receive the cam followers. A pair of cam tracks arranged in an outer surface of the male housing engage the cam followers which extend through the slots. A rotary actuator plate having two symmetrical grooves provided around a downwardly projecting pin is attached to the rail connecting portion by inserting the pin in the axis hole. The upwardly projecting pins are received in the grooves of the actuator plate which can be rotated with a relatively small force to engage and disengage the housings and the terminals provided therein.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
224 words
A multi-terminal connector comprising: a female housing having a plurality of male terminals stored therein; a male housing having a plurality of female terminals stored therein; a plurality of guide rails, at least two of which are connected to each other by a connecting portion provided with an axis hole at a center portion thereof on a longer side edge wall of an enlarged body portion of said female housing, said guide rails intersecting at right angles to the axes of said male terminals; a pair of sliders with each slider slidably engageable with said guide rails and having a pin projecting upwardly from a top surface and a cam follower projecting downwardly from a lower portion thereof; a pair of longitudinally aligned slots formed between said at least two guide rails with said connected center portion for permitting each of said cam followers to extend therethrough; a pair of cam tracks arranged in an outer surface of said male housing and symmetrically extending rearward in a diagonal direction from the lateral ends thereof to receive said respective cam followers extending through said slots; and a rotary actuator plate provided with two symmetrical grooves provided around a pin projecting downwardly from a center portion thereof and adapted to be attached to said rail connecting portion by insertion of said pin through said axis hole.
