Abstract

A quick-connect, quick-disconnect positive locking coaxial connector, suitable for radio frequency circuits and employing a single movable locking sleeve to lock a standard jack into a socket. The connector includes a spring type female terminal encased in an insulator block. An annular shield protects the locking members which are connected to the locking sleeve by angle extensions in slots in the shield.

Claims

1. An electrical connector for a coaxial line comprising:

a. a female portion having a hollow axial connecting terminal surrounded by a tubular insulator, and including an outer conductive cylinder and an inner locking plug for holding the tubular insulator in place;

b. a locking sleeve slidably positioned on the outer conductive cylinder integrally connected to a plurality of locking fingers;

c. an annular shield secured to the outer cylinder formed with slots for the passage of a flange which supports the locking fingers; and

d. a male portion having an axial conductive extension for entering the connecting terminal and supported by a tubular cylinder formed with an annular groove for engagement by the ends of said locking fingers when the male and female portions are joined.

2. An electrical connector according to claim 1 wherein said tubular insulator is formed in two pieces for clamping the connecting terminal and holding it in place.

3. An electrical connector according to claim 1 wherein said locking sleeve is formed with an inwardly extending flange for supporting the locking fingers at a position where they surround the male portion when the male portion is joined to the female portion.

4. An electrical connector as claimed in claim 1 wherein the annular shield is provided with an inwardly extending ledge for making contact with the ends of said fingers and for forcing them into the annular groove in the male member.

5. An electrical connector as claimed in claim 1 wherein said annular shield is secured to the outer conductive cylinder by solder prepositioned in a groove.

6. An electrical connector as claimed in claim 1 wherein said locking plug is threaded into the outer cylinder for securing two portions of the tubular insulator in place.

7. An electrical connector as claimed in claim 1 wherein said locking plug is formed with an axial hole for supporting a coaxial line.

8. An electrical connector as claimed in claim 1 wherein said annular shield is secured to the outer conductive cylinder by glue.

9. An electrical connector as claimed in claim 1 wherein the locking sleeve includes at least four spaced locking fingers.

10. An electrical connector as claimed in claim 1 wherein the ends of the locking fingers are bent radially inwardly to facilitate positioning in the annular groove of the tubular sleeve.
