Abstract

The electrical connector has a tubular sleeve and an outer tubular housing disposed over the tubular sleeve with at least two openings in the outer tubular housing to receive projections from the tubular sleeve. A resilient member biases the tubular sleeve and outer tubular housing relative to one another. Moving the outer tubular housing relative to the tubular sleeve pushes the projections radially inward to release the electrical connector. In an alternative embodiment, moving the outer tubular housing pulls the projections radially outward releasing the electrical connector.

Claims

1. An electrical connector for mounting on an end of a coaxial cable comprising:

a tubular sleeve configured to be mounted to a coaxial cable, the tubular sleeve comprising;

a front end, a back end, and a middle portion,

at least two spring fingers extending between the front end and the middle portion and having outwardly extending projections at the front end thereof; and

a forward facing shoulder disposed between the back end and the middle portion;

an outer tubular housing slidingly disposed over the tubular sleeve, the outer tubular housing having a first distal portion having a first diameter and a second proximal portion having a second diameter, the first diameter being smaller than the second diameter, the outer tubular housing extending beyond the front end of the tubular sleeve;

at least two openings disposed in the first distal portion to receive the projections from the at least two spring fingers, the at least two openings disposed a predetermined distance from a front end thereof; and

a resilient member disposed around the tubular sleeve, a first portion engaging the forward facing shoulder and a second portion engaging a rearward facing surface on an interior surface of the outer tubular housing to bias the outer tubular housing in a forward direction relative to the tubular sleeve.

2. The electrical connector according to claim 1, wherein sliding the outer tubular housing rearwardly causes the projections to be pushed inwardly and out of the openings by a forward portion of the outer tubular housing.

3. The electrical connector according to claim 1, wherein the front end of the tubular sleeve is rearward of the front end of the outer tubular housing when the outer sleeve is biased in a forward position.

4. The electrical connector according to claim 1, further comprising a washer disposed between the resilient member and the rearward facing surface on the interior surface of the outer tubular housing.

5. The electrical connector according to claim 1, further comprising a center contact and a dielectric disposed around the center contact, the center contact and dielectric being disposed in the tubular sleeve and a front end of the center contact extends forward of the outer tubular housing.

6. The electrical connector according to claim 1, further comprising a center contact and a dielectric disposed around the center contact, the center contact and dielectric being disposed in the tubular sleeve and a front end of the center contact extends forward of the tubular sleeve and proximal of a forward end of the outer tubular housing.

7. An electrical connector comprising:

a first connector portion comprising;

an inner tubular sleeve having a distal portion, a medial portion, and a proximal portion, the distal portion having at least two segmented elements, the at least two segmented elements each having a projection extending radially inward and having a rearward facing surface, the medial portion having a forward facing surface on an interior portion of the inner tubular sleeve and a rearward facing surface on an external portion of the inner tubular sleeve, and

an outer tubular sleeve slidingly disposed over the inner tubular sleeve and having a distal portion and a proximal portion, the proximal portion disposed over the proximal portion of the inner tubular sleeve and having a first internal diameter, and the distal portion disposed over the distal and medial portions of the inner tubular sleeve and having a second internal diameter that is greater than the first internal diameter, the distal portion having an inward and backward extending projection at a front end to engage and force the at least two segmented elements radially outward when the outer tubular sleeve is moved rearwardly relative to the inner tubular sleeve; and

a second connector portion to be mated with the first connector portion, the second connector portion having a chamfered front portion extending to a rearward facing surface and configured to fit within the distal portion of the inner tubular sleeve, the projections on the at least two segmented elements engaging the rearward facing surface of the second connector portion when mated therewith.

8. The electrical connector according to claim 7, further comprising a center contact and a dielectric disposed around the center contact, the center contact and dielectric being disposed in the inner tubular sleeve and a front end of the center contact being aligned with the forward facing surface on the interior portion of the inner tubular sleeve.

9. The electrical connector according to claim 7, wherein both projections have chamfered portions and the chamfered portions make contact with one another as the outer tubular sleeve is moved rearwardly relative to the inner tubular sleeve.

10. The electrical connector according to claim 7, further comprising a center contact and a dielectric disposed around the center contact, the center contact and dielectric being disposed in the inner tubular sleeve and a front end of the center contact extends forward of the forward facing surface on the interior portion of the inner tubular sleeve.
