Connector with outer conductor axial compression connection and method of manufacture
View Patent ↗An electrical connector for a coaxial cable with a solid outer conductor, the connector in combination with a cable and a method of manufacturing. The electrical connector having a connector body with a bore between a connector end and a cable end. The bore having an inner diameter shoulder at the cable end. A cylindrical sleeve positioned in the bore abutting the inner diameter shoulder. An annular groove open to the cable end, between the cylindrical sleeve and the cable end of the connector body. The annular groove dimensioned to receive an end of the solid outer conductor.
1. An electrical connector for a coaxial cable with a solid outer conductor comprising:
a connector body with a bore between a connector end and a cable end; the bore having an inner diameter shoulder at the cable end;
a cylindrical sleeve positioned in the bore abutting the inner diameter shoulder;
an annular groove open to the cable end, between the cylindrical sleeve and the cable end of the connector body; the annular groove dimensioned to receive an end of the solid outer conductor; and the cylindrical sleeve has a sleeve inner diameter substantially equal to a corrugation bottom diameter of the outer conductor.
2. The connector of claim 1 , wherein the cylindrical sleeve has a notch(s) dimensioned to receive a lead helical corrugation(s) of the end of the solid outer conductor.
3. The connector of claim 1 , wherein the connector body extends toward the cable end farther than the cylindrical sleeve by greater than twice a thickness of the solid outer conductor.
4. The connector of claim 1 , further including a center contact supported coaxial within the bore by an insulator.
5. The connector of claim 1 , wherein the cylindrical sleeve is press fit into the inner diameter shoulder.
6. The connector of claim 1 , wherein the annular groove is formed between the cylindrical sleeve and the cable end of the connector body by an outer diameter step in the cable end of the cylindrical sleeve.
7. The connector of claim 1 , wherein the annular groove is formed between the cylindrical sleeve and the cable end of the connector body by an inner diameter step in the cable end of the connector body.
8. The connector of claim 1 , wherein the cylindrical sleeve is formed from a first material having a greater rigidity characteristic than a second material of the connector body.
9. The connector of claim 8 , wherein the second material is a magnesium alloy.
10. The connector of claim 1 , further including a connector interface at the connector end.
11. A connector in combination with a coaxial cable having a solid outer conductor, comprising:
a connector body with a bore between a connector end and a cable end; the bore having an inner diameter shoulder at the cable end;
a cylindrical sleeve positioned in the bore abutting the inner diameter annular shoulder;
an annular groove open to the cable end between the cable body and the cylindrical sleeve; the annular groove dimensioned to receive an end of the solid outer conductor;
the end of the solid outer conductor retained in the annular groove by inward deformation of the cable end of the connector body; and
the cylindrical sleeve has a sleeve inner diameter substantially equal to a corrugation bottom diameter of the outer conductor.
12. The apparatus of claim 11 , wherein the inward deformation of the cable end of the connector body is applied until the cable end of the connector body has a diameter less than an inner diameter of the annular groove.
