Abstract

An improved suspension connector assembly is provided that is particularly adapted for use with a multiple pin and barrel type electrical connector. The suspension connector assembly includes a female connector mounted within a stationary housing, a movable male connector adapted to be raised and lowered toward and away from the female connector via the cable of a hoisting mechanism, and a latching mechanism for latching and unlatching the male connector to the female connector when the two are mutually engaged for a latching stroke distance. A resilient mounting assembly interconnects the female connector with the stationary housing. The stroke of the resilient mounting assembly is at least as long as the latching stroke distance of the latching mechanism so that the pins and barrels of the male and female electrical connectors will not be partially pulled apart from one another as a result of the stroke of the latching mechanism.

Claims

1. An improved suspension connector assembly of the type having a female connector mounted within a stationary housing, a movable male connector adapted to be raised and lowered toward and away from said female connector, and a latching mechanism for latching and unlatching said male connector to and from said female connector when said male connector is engaged against said female connector and then withdrawn from said female connector in a reciprocating movement having a latching stroke length (L1), wherein the improvement comprises:

a plurality of electrical connector pins on said male connector, and a plurality of connector barrels in said female connector registrable with said connector pins, said pins being insertable within said connector barrels when an engagement force is applied between said male and female connectors, and

means for resiliently mounting said female connector to said housing for applying a biasing force to said female connector that is greater than said engagement force necessary to insert said pins into said barrels to insure such insertion during the engagement portion of said reciprocating movement, and having a resiliency stroke at least as long as said latching stroke length (L1) such that said resiliency stroke allows the female connector to follow the male connector and thus for preventing the withdrawal of said pins from said barrels during the latching operation of said latching mechanism.

2. The improved suspension connector assembly as defined in claim 1, wherein the improvement further comprises a housing portion for covering said pins of said male connector when said pins initially engage said barrels of said female connector.

3. The improved suspension connector assembly as defined in claim 1, wherein the improvement further comprises means for aligning said connector pins and barrels into registry when said male connector is raised into engagement with said female connector.

4. The improved suspension connector assembly as defined in claim 1, wherein said female connector includes a body, and said resilient means includes at least one spring connected between said housing and said female connector body.

5. The improved suspension connector assembly as defined in claim 4, wherein said resilient means further includes a guide rod mounted on one or the other of said housing and said connector body, and a guide sleeve for slidably receiving said guide rod that is likewise mounted on one or the other of said housing and said connector body.

6. The improved suspension connector assembly as defined in claim 5, wherein said spring is concentrically disposed around said guide rod.

7. The improved suspension connector assembly as defined in claim 6, wherein said resilient means further includes a means for adjusting the length of said resiliency stroke.

8. The improved suspension connector assembly as defined in claim 7, wherein said length adjusting means includes at least one adjustment screw slidably disposed within a bore provided in said female connector.

9. The improved suspension connector assembly as defined in claim 8, wherein said adjustment means further includes a retaining sleeve concentrically disposed within said bore for retaining a head of said adjustment screw.

10. An improved suspension connector assembly, comprising:

a female connector having a connector body mounted with a stationary housing, said connector body having a plurality of electrical connector barrels;

a movable male connector adapted to be raised and lowered toward and away from said female connector, said male connector having a plurality of electrical connector pins registrable with and insertable into said connector barrels of said female connector body when an engagement force is applied between said female and male connectors;

a latching mechanism for latching and unlatching said male connector to and from said female connector when said male connector is engaged against said female connector and then withdrawn from said female connector in a reciprocating movement having a latching stroke length (L1);

means for resiliently mounting said female connector to said housing, including a support plate secured within said housing for supporting the body of said female connector, and

means for slidably and resiliently connecting said body of said female connector to said support plate,

wherein said resilient mounting means applies a biasing force to said female connector that is greater than said engagement force necessary to insert said pins into said barrels to insure such insertion during the engagement portion of said reciprocating movement, and has a resiliency stroke at least as long as said latching stroke length (L1) such that said resiliency stroke allows the female connector to follow the male connector and thus for preventing the withdrawal of said pins from said barrels during the latching operation of said latching mechanism.

11. The improved suspension connector assembly as defined in claim 10, wherein said resilient mounting means further includes a biasing spring for biasing a slidable movement of said body of said female connector with said force that is greater than said engagement force.

12. The improved suspension connector assembly as defined in claim 10, further comprising means for aligning said pins of said male connector with said barrels of said female connector when said male connector initially engages against said female connector.

13. The improved suspension connector assembly as defined in claim 12, further comprising means for adjusting the length of said resiliency stroke of said resilient mounting means.

14. The improved suspension connector assembly as defined in claim 13, wherein said length adjusting means includes at least one adjustment screw slidably disposed within a bore provided in said female connector.

15. The improved suspension connector assembly as defined in claim 14, wherein said adjustment means further includes a retaining sleeve concentrically disposed within said bore for retaining a head of said adjustment screw.
