Abstract

A coaxial connector includes front and rear bodies and front and rear contacts that can float relative to one another during mating with another coaxial connector. A wave washer between the front and rear bodies ensures a high quality contact between the front and rear bodies and urges the front and rear bodies toward axial parallel alignment with one another. Similarly, a spring between the front and rear contacts permits the front contact to float with the front body and relative to the rear contact and the rear body. The spring between the front and rear contacts maintains signal transmission capabilities.

Claims

1. A coaxial connector for mounting to a circuit board, said connector comprising:

a body assembly having a rear body with means for secure mounting to the circuit board, a front body floatably moveable relative to the rear body and a spring between the front and rear bodies for maintaining electrical contact therebetween for all relative positions of said front and rear bodies; and

a contact assembly comprising a rear contact concentrically fixedly supported within said rear body, said rear contact having means for secure mounting to the circuit board, a front contact spaced from said rear contact and being concentrically supported with said front body, and a resiliently deflectable connecting means extending between said front and rear contacts for maintaining signal transmission between said front and rear contacts for all relative floatably moveable positions of said front contact relative to said rear contact.

2. The coaxial connector of claim 1, further comprising an insulator disposed between said body assembly and said contact assembly, said insulator maintaining separation between said body assembly and said contact assembly and supporting said front contact of said contact assembly relative to said front body.

3. The coaxial connector of claim 2, wherein said insulator is dimensioned for movement relative to said rear contact in response to floating movement of said front body and said front contact.

4. The coaxial connector of claim 2, wherein said insulator comprises front and rear insulators rigidly engaged with one another and rigidly engaged in said front body, said front and rear insulators being formed to define a space therebetween, said resiliently deflectable connecting means and portions of said front and rear contacts being disposed in said space between said front and rear insulators.

5. The coaxial connector of claim 1, wherein the spring comprises a wave washer extending between said front and rear bodies.

6. The coaxial connector of claim 1, wherein said resiliently deflectable connecting means of said contact assembly comprises a coil spring, said coil spring having a rear end concentrically surrounding portions of said rear contact and a front end concentrically surrounding portions of said front contact.

7. A coaxial connector for mounting to a circuit board, said connector comprising:

a rear body having front and rear faces and a passage extending therebetween, an inwardly extending flange in said passage, and ground connection means projecting from said rear body for soldered connection to a ground on the circuit board;

a tubular front body movably mounted through said inwardly extending flange of said rear body, said front body including an outwardly extending rear flange disposed rearwardly of said inwardly extending flange of said rear body and an outwardly extending front flange forwardly of said rear body;

a wave washer biasingly engaged between said front face of said rear body and said front flange of said front body for maintaining electrical connection between said front and rear bodies;

a generally tubular rear insulator having opposed front and rear ends and a passage extending therebetween, an inwardly extending flange at said rear end of said rear insulator, said rear insulator being securely engaged within said tubular front body;

a front insulator having front and rear ends and a passage extending therethrough, said front insulator being securely engaged in said tubular front body forwardly of said flange of said rear body;

a rear contact having opposed front and rear ends, said rear end of said rear contact being securely connectable to a signal-carrying conductor on the circuit board, the front end of said rear contact being fixedly disposed between said front insulator and said flange of said rear insulator;

a front contact having front and rear ends, portions of said front contact intermediate said ends being securely engaged in said passage through said front insulator, said rear end of said front contact being disposed between said front insulator and said rear contact; and

a coil spring extending between and connecting said front and rear contacts, for permitting floatable movement of said front and rear contacts relative to one another and for maintaining signal transmission therebetween.

8. The coaxial connector of claim 7, wherein said rear contact includes a flange in proximity to said front end, said front contact including a flange in proximity said rear end, said coil spring being engaging against said flanges of said front rear contacts for contributing to signal transmission and for urging said front and rear contacts away from one another.
