Abstract

An electrical connector comprises a dielectric body having a socket. A plurality of pivotable arms are hinged to the dielectric body. A releasable locking mechanism holds the pivotable arms in a locked position that releases with an outward pulling force exceeding a threshold force. The releasable locking mechanism comprises two or more latch members that are biased by corresponding springs against the corresponding pivotable arms. Each pivotable arm has a protrusion that divides a first region from a second region of the pivotable arm.

First claim

The following is claimed:

1. An electrical connector comprising:
a dielectric body having a socket;
a plurality of pivotabie arms hinged to the dielectric body to pivot about a pivot point or axis;
a releasable locking mechanism to hold the pivotable arms in a locked position of a closed state that releases with an outward pulling force exceeding a threshold force; wherein the releasable locking mechanism comprises two or more latch members that are biased by corresponding springs against the corresponding pivotable arms, each pivotable arm having a curved sloped protrusion that extends above a surface of each pivotable arm with a slope and height of the curved sloped protrusion establishing the threshold force of a transition between the Closed state and an open state and that where the curved sloped protrusion divides a first region from a second region of the pivotable arm; and
each of the pivotabie arms comprising a bore at the axis, each bore associated with a raised annular protrusion or spacer about the bore to prevent axial movement of the pivotabie arms.

2. The electrical connector according to claim 1 wherein the latch members comprise transversely slidable pins.

3. The electrical connector according to claim 2 wherein one, end of each of the slidable pins is substantially hemispherical.

4. The electrical connector according to claim 1 wherein each pivotable arm, among the plurality of pivotabie arms, has an inner protrusion and an outer protrusion, the outer protrusion on an opposite side of the pivotabie arm from the inner protrusion, the inner protrusion dividing a first inner region from a second inner region of the pivotable arm, the outer protrusion dividing a first outer region from a second outer region of the pivotable arm.

5. The electrical connector according to claim 4 wherein latch members comprise two latch members per each pivotable arm.

6. The electrical connector according to claim 1 wherein sets of latch members and springs are in corresponding bores of a fulcrum portion, and wherein a threaded retainer retains each of the sets in its corresponding bore.

7. The electrical connector according to claim 1 wherein the pivotable arms are connected by a cross member and wherein one pivotable arm terminates in a lever.

8. The electrical connector according to claim 1 further comprising:
a connector plug for insertion into the socket, and wherein a mating surface of the pivotable arms contacts the connector plug if the connector plug is inserted into the socket.

9. The electrical connector according to claim 1 further comprising:
a rotatable cover pivotally connected to the dielectric body.

10. An electrical connector comprising:
a dielectric body having a socket;
a plurality of pivotable arms hinged to the dielectric body to pivot about a pivot point or axis;
a releasable locking mechanism to hold the pivotable arms in a locked position of a closed state that release with an outward pulling force exceeding a threshold force; wherein the releasable locking mechanism comprises two or more latch members that are biased by corresponding springs against the corresponding pivotable arms, each pivotable arm having a curved sloped protrusion that extends above a surface of each pivotable arm with a slope and height of the curved sloped protrusion establishing the threshold force of a transition between the closed state and an open state, the curved sloped protrusion dividing a first region from a second region of the pivotable arm; and
each of the pivotable arms comprising a bore at the axis, each bore having, or associated with, a raised annular protrusion or spacer about the bore to prevent axial movement of the pivotable arms.

11. An electrical connector for connecting to a connector plug, the electrical connector comprising:
a dielectric body having a socket;
a plurality of pivotable arms hinged to the dielectric body to pivot about a pivot point or axis;
a releasable locking mechanism hinged about the pivot point on the dielectric body to hold a connector plug in an inserted position of a closed state and that releases when the connector plug is pulled from the socket with a force exceeding a threshold force; wherein the releasable locking mechanism comprises two or more latch members that are biased by corresponding springs against corresponding pivotable arms, each pivotable arm having a curved sloped protrusion that extends above a surface of each pivotable arm with a slope and height of the curved sloped protrusion establishing the threshold force of a transition between the closed state and an open state, the curved sloped protrusion dividing a first region from a second region of the pivotable arm; and
each of the pivotable arms comprising a bore at the axis, each bore having, or associated with, a raised annular protrusion or spacer about the bore to prevent axial movement of the pivotable arms.

12. The electrical connector according to claim 11 wherein each one of the latch members comprises a transversely slidable pin.

13. The electrical connector according to claim 12 wherein one end of the slidable pin is substantially hemispherical.

14. The electrical connector according to claim 11 wherein each pivotable arm has an inner protrusion and an outer protrusion, the outer protrusion on an opposite side of the pivotable arm from the inner protrusion, the inner protrusion dividing a first inner region from a second inner region of the pivotable arm, the outer protrusion dividing a first outer region from a second outer region of the pivotable arm.

15. The electrical connector according to claim 14 wherein latch members comprise two latch members per each pivotable arm.

16. The electrical connector according to claim 14 further comprising a threaded retainer for a set of latch members and springs in a bore.

17. The electrical connector according to claim 11 wherein the pivotable arms are connected by a cross member and wherein one pivotable arm terminates in a lever.

18. The electrical connector according to claim 11 wherein a mating surface of the pivotable arms contacts the connector plug if the connector is closed.

19. The electrical connector according to claim 11 further comprising:
a rotatable cover pivotally connected to the dielectric body.

20. The electrical connector according to claim 19 wherein the cover has a closed position that covers or protects the socket.

21. The electrical connector according to claim 1 wherein the raised annular portion or spacer is approximately a peak height of the corresponding sloped protrusion that extends above the surface of the pivotable arms.

22. The electrical connector according to claim 1 wherein the raised annular protrusion or spacer facilitates proper alignment between the sloped protrusion and a corresponding one of the latch members.
