Abstract

A high performance coaxial connector used to terminate a coaxial cable and provide an electrical connection to a mating coaxial connector is disclosed. The coaxial connector is formed with few individual parts and may be configured to provide enhanced electrical performance greater than or equal to 4 GHz.

Claims

1. A coaxial connector, comprising:

a shell comprising a front cylindrical section and a collar having a rear edge adjacent the collar;

the front cylindrical section comprising slots configured to receive locking pins of a female connector;

a center conductor housing comprising a forward cylindrical section, a flange, and a crimp section disposed coaxially within the shell;

a gasket positioned between the shell and the flange;

a spring mechanism disposed between the flange and the rear rolled edge

wherein the spring mechanism allows the center conductor housing axial movement within the shell; and

a dielectric disposed coaxially within the forward cylindrical section;

wherein the collar comprises tabs that are folded inward to form the rear edge that urges the spring mechanism toward the center conductor.

2. The connector of claim 1, wherein the forward cylindrical section comprises displaced material for securing the dielectric therewithin.

3. The connector of claim 1, wherein the forward cylindrical section further comprises forward extending tines.

4. The connector of claim 1, wherein the shell further comprises flaps configured to partially cover the slots.

6. The connector of claim 1, wherein the dielectric spacer comprises an axial through hole configured to receive a conductive pin.

7. The connector of claim 1, wherein the connector is configured to provide enhanced electrical performance greater than or equal to 4 GHz.

5. (canceled)

8. A coaxial connector assembly, comprising:

a coaxial connector comprising;

a shell comprising a front cylindrical section having slots and a collar having a rear edge;

a center conductor housing comprising a forward cylindrical section, a flange, and a crimp section disposed coaxially within the shell;

a gasket positioned between the shell and the flange;

a spring mechanism disposed between the flange and the rear edge configured to allow the center conductor housing axial movement within the shell; and

a dielectric spacer disposed coaxially within the forward cylindrical section, the dielectric spacer comprising an axially aligned through hole configured to receive a conductive pin;

wherein the collar comprises tabs that are folded inward to form the rear edge that urges the spring mechanism toward the center conductor; and

a conductive pin for attachment to a coaxial cable center wire.

9. The connector assembly of claim 8, further comprising a crimping sleeve to attach a coaxial cable to the crimp section.

10. The connector assembly of claim 8, wherein the forward cylindrical section comprises displaced material for securing the dielectric spacer within the forward cylindrical section.

11. The connector assembly of claim 8, wherein the forward cylindrical section further comprises forward extending tines.

12. The connector assembly of claim 8, wherein the shell further comprises flaps configured to partially cover the slots.

13. The connector assembly of claim 8, wherein the flaps are formed by folding forward flaps of the front cylindrical section.

15. The connector assembly of claim 8, wherein the connector is configured to provide enhanced electrical performance greater than or equal to 4 GHz.

14. (canceled)

16. A method of forming a coaxial connector, comprising:

providing an pre-assembled shell comprising a front cylindrical section and a collar comprising tabs;

inserting a gasket into the shell;

inserting an inner conductive housing comprising a forward cylindrical section, a flange, and a crimping portion into the shell whereby the flange contacts the gasket;

placing a spring mechanism in contact with the flange; and

folding the tabs of the collar against the spring mechanism to form the coaxial connector.

17. The method of claim 16, including disposing a dielectric within the forward cylindrical section of the inner conductive housing.

18. The method of claim 16, further comprising attaching a conductive pin to a center wire of a coaxial cable, inserting the conductive pin into a through hole of the dielectric, and crimping a locking mechanism around the coaxial cable to secure the coaxial cable to the crimping portion of the shell.

19. The method of claim 16, wherein the dielectric is secured within the forward cylindrical section of the inner conductive housing by barbs formed into the forward cylindrical section.

20. The method of claim 16, wherein the connector is configured to provide enhanced electrical performance greater than or equal to 4 GHz.
