Abstract

A ganged electrical connection system includes an arrangement having a spring including a plurality of engagement portions. A plurality of first connectors is receivably coupled in a plurality of receptacles in the arrangement and a plurality of second connectors is matable to the coupled first connectors along mating axes. The plurality of coupled first connectors have floatable movement in the plurality of receptacles. The floatable movement is in at least an axial direction in relation to the plurality of receptacles and the axial positional mating tolerance variation of each second connector in the plurality of second connectors in relation to each first connector in the plurality of coupled first connectors that manifests at each receptacle in the plurality of receptacles is assimilated by each respective spring engagement portion when the plurality of second connectors mate to the plurality of coupled first connectors.

Claims

1-3. -3. (canceled)

8. An electrical connection system comprising:

an arrangement defining a plurality of receptacles and including a spring having a plurality of engagement portions in communication with the plurality of receptacles;

a plurality of first connector housings respectively including at least one electrical contact, said plurality of first connector housings being receivably coupled in the plurality of receptacles; and

a plurality of second connector housings including at least one mating electrical contact, said plurality of second connector housings being matable to the plurality of coupled first connector housings along mating axes and the at least one mating electrical contact being matable to the at least on electrical contact of the plurality of coupled first connector housings also along said mating axes,

wherein the plurality of receptacles are configured for floatable movement of the plurality of coupled first connector housings therein, said floatable movement being in at least an axial direction in relation to the plurality of receptacles so that axial positional mating tolerance variation of each second connector housing in the plurality of second connector housings in relation to each coupled first connector housing in the plurality of coupled first connector housings that manifests at each receptacle in the plurality of receptacles is assimilated by each respective spring engagement portion in the plurality of engagement portions of the arrangement when the plurality of second connector housings mate to the plurality of coupled first connector housings and said at least one mating electrical contact associated with plurality of second connector housings mate with said at least one electrical contact associated with the plurality of coupled first connector housings.

4. The electrical connection system according to claim 8, wherein the arrangement comprises a support frame and the spring is formed as a single contiguous piece secured to the support frame, the spring and the arrangement being respectively formed from the same material.

5. The electrical connection system according to claim 8, wherein each first connector housing in the plurality of first connector housings includes a forward and a rearward section and the spring further includes a non-engagement portion,

said forward section of each coupled first connector engagingly contacts each respective engagement portion when said axial positional mating tolerance variation is manifested at the respective receptacle in the plurality of receptacles, and

said non-engagement portion is disposed intermediate the respective plurality of engagement portions of the spring and a support frame so as to communicate with both the engagement portions and the support frame, said non-engagement portion securing the spring to the support frame.

6. The electrical connection system according to claim 8, wherein the plurality of receptacles are formed in the arrangement to constitute a row that is generally perpendicular to the mating axes, and said plurality of engagement portions of the spring have an adjacent, parallel relationship axially aft of said plurality of receptacles in said row.

7. The electrical connection system according to claim 8, wherein each spring engagement portion is moveable in the axial direction by engagement with a coupled first connector housing in the plurality of coupled first connector housings when said axial positional mating tolerance variation is manifested at a receptacle in the plurality of receptacles when a second connector housing in the plurality of second connector housings mates with a coupled first connector housing in the plurality of coupled first connector housings.

9. The electrical connection system according to claim 8, wherein each first connector housing in the plurality of first connector housings includes a forward section and a rearward section and the spring further includes a non-engagement portion, and

an edge of said forward section of each coupled first connector housing engagingly contacts each respective engagement portion when said axial positional mating tolerance variation is manifested at the respective receptacle in the plurality of receptacles, and

said non-engagement portion is disposed intermediate the respective plurality of engagement portions of the spring and a support frame so as to communicate with both the engagement portions and the support frame, and a portion of the non-engagement portion engages with an aperture defined in the arrangement to secure the spring thereto.

10. The electrical connection system according to claim 8, wherein the spring is attachingly secured to the arrangement in a molding process.

11. The electrical connection system according to claim 8, wherein

the spring is formed of a dielectric material, and

the arrangement is formed of a dielectric material,

wherein said dielectric spring is attached to said dielectric arrangement thereto without the use of a fastener.

12. The electrical connection system according to claim 11, wherein each first connector housing in the plurality of first connector housings includes a forward section and a rearward section and the dielectric spring further includes a non-engagement portion, and

an edge of said forward section of each coupled first connector housing engagingly contacts each respective engagement portion when said axial positional mating tolerance variation is manifested at the respective receptacle in the plurality of receptacles, and

said non-engagement portion is disposed intermediate the respective plurality of engagement portions of the dielectric spring and a support frame so as to communicate with both the engagement portions and the support frame, and a portion of the non-engagement portion engages with an aperture defined in the dielectric arrangement to secure the dielectric spring thereto.
