Abstract

Discloses novel contact drivers in electric connectors. The electric connectors respectively provided with a series of contacts each of which has a movable end. Pin conductors are inserted into positions in which the pin conductors remain out of contact with the contacts. By operating a slider which is slidable longitudinally along the connector, the movable ends of the contacts are brought into contact with the pin conductors.

Claims

1. A contact driver comprising a contact mount formed as a single molding of a dielectric material having a series of recesses, a set of contacts arranged in said recesses of the molding, each of said contacts having a movable end, conductors arranged in positions in which the conductors remain out of contact with said contacts in said recesses of the molding, a plurality of cam members adapted to be driven separately from each other and mounted to said molding so as to cooperate with said contacts respectively, and a slider longitudinally slidable along said molding whereby to operate said cam members in regular succession so as to move the movable ends of said contacts to relative positions in which the movable ends are in contact with said conductors.

2. A contact driver as claimed in claim 1, wherein each of said contacts comprises a base rigidly secured to said molding and a movable end extending from said base.

3. A contact driver as claimed in claim 1, wherein said cam members are respectively moved along the longitudinal axis of said contacts.

4. A contact driver as claimed in claim 1, wherein said cam members are rotary disc cams.

5. A contact driver as claimed in claim 1, wherein said slider is provided with a guide channel or channels cooperating with said cam members.

6. A contact driver as claimed in claim 1, wherein each of said contacts comprises a base rigidly secured to said molding and a bifurcate movable end extending from said base.

7. A contact driver as claimed in claim 6, each of said cam members is made rotatable on the side of the bifurcate movable end extending from the base of each contact.

8. A contact driver as claimed in claim 1, wherein a pair of contacts are arranged in each of said recesses formed in said molding.

9. A contact driver as claimed in claim 8, wherein each of said pair of contacts arranged in each recess in the molding comprises a base secured to said molding and a movable end curved in U-shape relative to said base.

10. A contact driver as claimed in claim 1, wherein said cam members are formed integral with said slider.

11. A contact driver as claimed in claim 1, said driver is formed as an arc of a circle in general.

12. A contact driver as claimed in claim 1, wherein said driver is formed as a segment of a circle in general.
