Abstract

Externally insulated coaxial connector ( 2 ) for connecting two electrical coaxial components, the connector comprising an insulative housing 6 defining first and second intersecting passageways ( 18, 20 ) for respectively receiving at least portions of the coaxial components and having central longitudinal axes ( 16, 22 ) which are not aligned with each other and may be mutually perpendicular. The connector further comprising a first shield member ( 54 ) which is at least partly accommodated by the first passageway ( 18 ) and a second shield member ( 120 ) which is at least partly accommodated by the second passageway ( 20 ) and is engageable with the first shield member ( 54 ) by movement of the second shield member ( 120 ) with respect to the second passageway ( 20 ). Engagement of the first and second shield members ( 54, 120 ) with each other and engagement of first and second core connection members ( 44, 110 ) with each other may be by means of push-fit inter-engagement.

First claim

The invention claimed is:

1. An externally insulated coaxial connector for connecting two electrical coaxial components, the connector comprising an insulative housing defining first and second intersecting passageways for respectively receiving at least portions of the coaxial components and having first and second respective longitudinal axes which are not aligned with each other, the connector further comprising a first shield member which is at least partly accommodated by the first passageway and a second shield member which is at least partly accommodated by the second passageway, the first shield member having an inner end and a contact end, the inner end having a first engagement member within an intersection of the first and second passageways and aligned with the second passageway, wherein the first shield member is engageable with the second shield member by movement of the second shield member along the second longitudinal axis, and first and second electrical terminals positioned within the first and second shield members.

2. The connector of claim 1 wherein the first and second longitudinal axes are substantially perpendicular to each other.

3. The connector of claim 1 wherein the shield members include push-fit inter-engagement means.

4. The connector of claim 3 wherein the push-fit inter-engagement means includes at least one resilient detent.

5. The connector of claim 4 wherein the push-fit inter-engagement means comprises an aperture in one of the shield members an inwardly facing surface of which is engaged by plural resilient detents of the other shield member.

6. The connector of claim 1 wherein the electrical terminal includes a first core connection member which is at least partly accommodated within one of the passageways and a second core connection member which is at least partly accommodated by the other passageway and is engageable with the first core connection member by movement of the second core connection member with respect to its respective passageway.

7. The connector of claim 6 wherein the core connection members include push-fit inter-engagement means.

8. The connector of claim 6 wherein the first shield member is hollow and accommodates the first core connection member with an insulation member therebetween.

9. The connector of claim 8 wherein the second core connection member extends through a clearance aperture in the first shield member and an aperture in the insulation member.

10. The connector of claim 6 wherein the shield member and the core connection member at least partly accommodated by one of the passageways are electrically isolated from each other by an annular insulation wall constituting part of the housing.

11. The connector of claim 1 configured for connection to a coaxial cable and a coaxial plug which constitute the two coaxial components.

12. The connector of claim 1 including a strain relief member including at least one barb positioned to bite into an external layer of a coaxial cable and configured to be urged deeper into the external layer as a consequence of urging of the cable outwardly of the housing.

13. The connector of claim 1 wherein the housing is a one-piece housing.

14. A method of assembling an externally insulated coaxial connector for connecting two electrical coaxial components, the method comprising the steps of: (a) providing a one piece insulative housing defining first and second intersecting passageways having central longitudinal axes which are not aligned with each other; (b) inserting a first core connection member within a first shield member and inserting the first core connection member and the first shield member at least partly into the first passageway towards the intersecting passageways; and (c) inserting a second shield member at least partly into the second passageway towards the intersecting passageways so that it engages and electrically connects with the first shield member at a position within the intersecting passageways.

15. The method of claim 14 including the additional step of positioning the first core connection member at least partly within the first shield member with an insulation member therebetween.

16. The method of claim 15 including the additional step of assembling the first core connection member, the first shield member, and the insulation member together into a first assembly, and positioning the first assembly into the first passageway; and inserting a second core connection member at least partly into the second passageway so that it engages and electrically connects with the first core connection member.

17. An insulated coaxial connector for connecting two electrical coaxial components, the connector comprising:
a one-piece insulative housing having two connecting passageways, with access to the passageways provided at each open end, and each passageway having a central longitudinal axis, the central longitudinal axes being non-aligned; and
coaxial shield and signal contact components being insertable through the open ends of the passageways and being electrically connected at a position within the intersection of the non-aligned central longitudinal axes.
