Abstract

A two-part connector can be achieved for high performance situations using blind-mate insertion by using power activation. In one embodiment, the male and female portions of a standard RF connector can be securely mated so as to achieve high performance without the need for a screw type locking mechanism. Power activation is achieved, in one embodiment, by pneumatic actuation of a piston having fingers which engage an outer edge of a housing formed around the female portion of the connector so as to pull the female portion into a tight mating relationship with the male portion.

Claims

1. A two-part in-line RF connector, comprising:

a first portion;

a passageway within said first portion, said passageway having a distal end and a proximal end, wherein said proximal end is configured to receive a second portion of said RF connector;

a piston having a portion thereof slideable along a longitudinal axis of said passageway;

a gripping collet positioned within said passageway and moveable along said longitudinal axis under control of said piston, said collet having fingers positioned facing said proximal end of said passageway; and

means for controllably expanding and contracting said fingers within said passageway.

2. The two-part in-line RF connector of claim 1 wherein said extending means comprises;

a slip bushing for protecting said fingers when said fingers are not extended; and

a cam bushing for forcing said fingers to extend into said passageway as said collet moves toward said distal end of said passageway.

3. The two-part in-line RF connector of claim 2 further comprising:

at least one opening for accepting forces applied from external of said apparatus, said forces selectably controlling movement of said piston.

4. The two-part in-line RF connector of claim 3 wherein a portion of said slip bushing forms an outer end of said passageway at said proximal end of said passageway.

5. The two-part in-line RF connector of claim 4 wherein said first portion comprises:

said at least one opening; and

said second portion comprises;

said passageway;

said collet within said passageway; and

said slip bushing; and

wherein said piston extends between said first and second portions.

6. The two-part in-line RF connector of claim 5 wherein said second portion has an outside circumference less than an outside circumference of said first portion.

7. The two-part in-line RF connector of claim 5 wherein said inside circumference of said collet within said passageway is such as to form a slip fit with an outside circumference with a collar surrounding at least a portion of said second portion of said RF in-line connector.

8. A method of securing two portions of a connector in mating relationship with each other, said method comprising:

positioning a first portion of said connector into mating relationship with a second portion of said connector, said positioning comprising inserting a shell formed at least partially around said first portion such that an outer surface of said shell comes into sliding contact with an inner surface of a passageway positioned in front of said second portion of said connector;

grasping a portion of said shell after said shell has passed a certain distance along said passageway, said grasping being controlled, at least in part, by force applied by the movement of a piston, a portion of which is positioned within said passageway; and

pulling said first and second portions into a sustained mated relationship with each other under control of said applied piston force.

9. The method of claim 8 wherein said grasping comprises:

opening a set of fingers, said fingers extending along a longitudinal axis of said shell; and

closing said fingers such that gripping ends of said fingers lock around a distal end of said shell.

10. The method of claim 8 wherein said passageway forms a straight-line passage from an opening in said passageway to an end of said second portion of said connector.

11. The method of claim 8 wherein said first portion of said connector is a female portion of a standard RF connector and wherein said second portion of said connector is a male portion of a standard RF connector.

12. The method of claim 8 wherein said applied piston force comprises, at least in part:

application of external force to said connection.

13. The method of claim 12 wherein said external force is provided by one of the following energy sources:

pneumatic, hydraulic, electrical.

14. A system for securing two portions of a connector in mating relationship with each other, said system comprising:

means for bringing a first portion of said connector into mating relationship with a second portion of said connector, said means for bringing comprising a passageway for allowing a shell formed at least partially around said first connector portion to slide within said passageway;

means positioned within said passageway for grasping a portion of said shell after said shell has passed a certain distance along said passageway;

a piston having at least a portion within said passageway;

means for activating said means positioned within said passageway under control of said piston; and

means controlled by said piston for pulling said first and second portions into a sustained mated relationship with each other.

15. The system of claim 14 further comprising:

means for applying external force to said piston.

16. The system of claim 15 wherein said external force is provided by one of the following energy sources:

pneumatic, hydraulic, electrical.

17. The system of claim 15 wherein said grasping means comprises:

means for opening and closing a set of fingers, said fingers extending along a longitudinal axis of said passageway.

18. The system of claim 17 wherein said opening and closing means comprises:

a cam bushing; and

a slip bushing; and

wherein said grasping means comprises a plurality of longitudinally extending fingers and wherein said slip bushing protects said fingers from contact with said shell while said shell is slides along at least a portion of said passageway.

19. The system of claim 18 wherein said grasping means further comprises:

a cam bushing for forcing said grasping means against said shell as said piston withdraws within said passageway.

20. The system of claim 17 wherein said first portion of said connector is a female portion of a standard RF connector and wherein said second portion of said connector is a male portion of a standard RF connector.
