Abstract

A floating connector adapted for use with microwave surgical instruments is presented. The disclosure provides for the use of cost-effective and readily available non-floating connectors in a floating housing which can compensate for dimensional variations and misalignments between the connectors. Multiple connectors of varying types can therefore be used within a single support housing without requiring the costly precision manufacturing processes normally associated with such multiple connector assemblies. The floating connector is suitable for use with electrical connections as well as fluidic connections.

Claims

1. A floating connector housing, comprising:

a spring plate comprising;

at least one slot defining a floating region concentrically disposed within a fixed region;

at least one spring beam defined in the spring plate coupling the floating region and the fixed region; and

a central opening defined therein;

a support member having an opening defined therein, wherein the central opening defined in the spring plate is positioned in substantially concentric alignment with the opening defined in the support member; and

at least one coupling member which attaches the spring plate to the support member.

2. The floating connector housing according to claim 1, wherein the at least one slot further defines at least one stop for limiting the range of motion of the floating region.

3. The floating connector housing according to claim 1, wherein the at least one slot is formed by a process selected from a group consisting of stamping, machining, injection molding, laser machining, water jet machining, chemical machining, blanking, fine blanking, compression molding, and extrusion with secondary machining.

4. The floating connector housing according to claim 1, wherein the coupling member is selected from a group consisting of at least one threaded fastener, at least one rivet, adhesive and welding.

5. The floating connector housing according to claim 1, wherein the spring plate and support member are integrally formed.

6. The floating connector housing according to claim 1, wherein the coupling member comprises a collar securing the spring plate to the support member.

7. The floating connector housing according to claim 1, wherein the opening defined in the support member further includes a recess defined at a circumferential edge thereof.

8. A floating connector housing, comprising:

a support member having an opening defined therein;

a floating member having a perimeter, and a central opening defined therein positioned in substantial concentric alignment with the opening defined in the support member; and

at least one elastomeric coupling member attaching the floating member to the support member.

9. The floating connector housing according to claim 8, wherein the perimeter of the floating member extends beyond the edge of the opening of the support member;

and

the elastomeric coupling member is disposed between the floating member and the support member along the perimetric interstice defined by the overlap therebetween.

10. The floating connector housing according to claim 8, wherein the perimeter of the floating member is positioned within the opening of the support member;

and

the elastomeric coupling member is disposed between the floating member and the support member along the annular interstice defined therebetween.

11. The floating connector housing according to claim 10, further comprising:

a first semicircular recess disposed along an inner edge of the opening of the support member;

a second semicircular recess disposed along the perimeter of the floating member;

wherein the elastomeric coupling member is an o-ring captured within the interstice defined between the first semicircular recess and the second semicircular recess.

12. The floating connector housing according to claim 8, wherein the elastomeric coupling member is constructed from material selected from a group consisting of rubber, neoprene, nitrile, silicone, foam rubber, and polyurethane foam.

13. The floating connector housing according to claim 8, further comprising a positive stop fixed to the support member and configured to limit lateral displacement of the floating member.

14. The floating connector housing according to claim 13, wherein the positive stop and the support member are integrally formed.

15. The floating connector housing according to claim 13, wherein the positive stop is fixedly disposed to the support member substantially adjacent to a perimeter of the opening.

16. The floating connector housing according to claim 13, wherein a standoff is disposed between the positive stop and the support member.

17. The floating connector housing according to claim 16, wherein the standoff and positive stop are integrally formed.

18. A spring plate, comprising:

a substantially planar substrate formed from resilient material;

a plurality of slots formed in the substantially planar substrate defining a floating region concentrically disposed within a fixed region;

at least one spring beam defined in the substantially planar substrate coupling the floating region and the fixed region; and

an opening defined in the floating region dimensioned to receive a mounting boss.

19. The spring plate according to claim 18, wherein the floating region includes at least one stop adapted to limit the range of motion of the floating region.

20. The spring plate according to claim 18, wherein the opening defined in the floating region includes opposing flat areas adapted to inhibit rotation of the mounting boss.
