Abstract

A female plug connector for receiving a standard jack has an outer sleeve having an annular edge at one end. On the interior of said sleeve are a locking surface of reduced diameter and a first and second containing surface of reduced diameter. The plug further has a tubular insert, slidably received in the outer sleeve, having at one end, longitudinally extending slits, forming slotted members to allow for radial expansion. The insert includes exterior protrusions of reduced diameter to be received in the annular groove of the jack, and an outer annular projection which bears against the locking surface of the outer sleeve when the plug is in the locked position. The tubular insert also has a first and second outer annular containing surface. The female plug connector further includes a first retaining means bearing against the first interior containing surface of the outer sleeve, and the first outer annular containing surface of the plug insert. A second retaining means bears against the second interior containing surface and the second outer annular containing surface of the plug insert. Disposed between the first and second retaining means is a spring for locating the outer sleeve in its normal position relative to the insert. A retainer ring is disposed around the slotted members of the insert, between the outer annular projections of the tubular insert and the first retaining means.

Claims

1. A female plug connector for use in combination with a standard male jack, said male jack including a tubular body having an annular groove disposed intermediate its length, said female plug connector comprising:

a. a tubular outer sleeve including;

i. an annular edge at one end;

ii. an interior locking surface of reduced diameter; and

iii. first and second interior containing surfaces;

b. a tubular insert slidably received in the outer sleeve, said tubular insert including;

i. at one end of said insert, longitudinally extending slits forming slotted members to allow radial expansion;

ii. interior reduced diameter protrusions corresponding in configuration to the annular groove of the jack.

iii. outer annular projections which bear against the locking surface of the outer sleeve when the female plug connector is in the locked position; and

iv. first and second outer containing surfaces;

c. a first retaining means bearing against the first interior containing surface of the outer sleeve and the first outer annular containing surface of the tubular insert;

d. a second retaining means bearing against the second interior containing surface of the sleeve and the second outer annular containing surface of the tubular insert;

e. biasing means disposed between the first and second retaining means for locating the outer sleeve in its normal position relative to the tubular insert; and

f. a retaining ring disposed around the slotted members of the tubular insert, between the outer annular projections of the tubular insert and the first retaining means.

2. A female plug connector as recited in claim 1 where the biasing means is a helical spring.

3. A female plug connector as recited in claim 1 where the first and second retaining means are split washers.

4. A female plug connector as recited in claim 1 where the retaining ring is made from beryllium copper.

5. A female plug connector as recited in claim 1 in which the tubular insert houses at least one inner conductor.

6. A female plug connector for use in combination with a standard male jack, said male jack including a tubular body having an annular groove disposed intermediate its length, said female plug connector comprising;

a. a tubular outer sleeve including;

i. an annular edge at one end;

ii. an interior locking surface of reduced diameter; and

iii. first and second interior containing surfaces;

b. a tubular insert slidably received in the outer sleeve, said tubular insert being able to house at least one inner conductor, said tubular insert including;

i. at one end of said insert, longitudinally extending slits forming slotted members to allow radial expansion;

ii. interior reduced diamter protrusions corresponding in configuration to the annular groove of the jack.

iii. outer annular projections which bear against the locking surface of the outer sleeve when the female plug connector is in the locked position; and

iv. first and second outer containing surfaces;

c. a first split washer bearing against the first interior containing surface of the outer sleeve and the first outer annular containing surface of the tubular insert;

d. a second split washer bearing against the second interior containing surface of the sleeve and the second outer annular containing surface of the tubular insert;

e. biasing means disposed between the first and second split washers for locating the outer sleeve in its normal position relative to the tubular insert; and

f. a beryllium copper retaining ring disposed around the slotted members of the tubular insert, between the outer annular projections of the tubular insert and the first retaining means.

7. A female plug connector as recited in claim 6 in which the biasing means is a helical spring.
