Coaxial connector inner contact arrangement
View Patent ↗An inner contact arrangement for a coaxial cable connector. The inner contact supported coaxially within a connector bore of the connector by a support insulator. A plurality of tines extending from a central portion of the inner contact, the tines may be angled outward from a longitudinal axis of the inner contact and or provided with a shoulder. A bias insulator with a ramp bore, the bias insulator retained within the connector bore and contacting the cable end of the tines.
1. An inner contact arrangement for a coaxial cable connector, comprising:
an inner contact supported coaxially within a connector bore of the connector by a support insulator;
a plurality of tines extending from a central portion of the inner contact, a cable end of the tines angled outward from a longitudinal axis of the inner contact;
a bias insulator with a ramp bore, the bias insulator retained within the connector bore;
the cable end of the tines contacting the ramp bore.
2. The arrangement of claim 1 , further including a shoulder on an inner surface of the tine(s), the shoulder spaced away from the cable end of the tines by a guide surface.
3. The arrangement of claim 1 , wherein the ramp bore has an increasing diameter in a direction from a cable end side to a connector end side.
4. The arrangement of claim 1 , wherein the outward angle of the tines begins at a position spaced away from a connector end of the tines.
5. The arrangement of claim 1 , wherein the tines are separated from each other by slots; the slots defining a longitudinal length of the tine(s).
6. The arrangement of claim 1 , wherein the bias insulator has an annular protrusion on an outer diameter; the annular protrusion retained within an annular groove of the connector bore.
7. The arrangement of claim 1 , wherein the bias insulator is retained stationary within the connector bore.
8. The arrangement of claim 1 , wherein the outward angle of the tines begins at a transition spaced away from a connector end of the tines; and further comprising
a shoulder on an inner surface of the tine(s), the shoulder positioned longitudinally along the tine(s) at the transition.
9. The arrangement of claim 1 , wherein a length of the tine(s) is between 3 and 8 times a radial thickness of the tine(s).
10. The arrangement of claim 1 , wherein the contacting between the cable end of the tines and the ramp bore swages the tines inward.
11. An inner contact arrangement for a coaxial cable connector, comprising:
an inner contact supported coaxially within a connector bore of the connector by a support insulator;
a plurality of tines extending from a central portion of the inner contact;
a shoulder on an inner surface of the tine(s), the shoulder spaced away from a cable end of the tines by a guide surface;
a bias insulator with a ramp bore, the bias insulator retained within the connector bore;
the cable end of the tine(s) contacting the ramp bore.
12. The arrangement of claim 11 , wherein the shoulder is located within a middle third of the longitudinal length of the tine(s).
13. The arrangement of claim 11 , wherein the tine(s) are angled outward between the shoulder and the cable end of the tine(s).
14. The arrangement of claim 11 , wherein a thickness of the tine(s) is reduced between the shoulder and the cable end of the tine(s).
15. The arrangement of claim 11 , wherein the tine(s) are swaged inward by the ramp bore.
16. The arrangement of claim 11 , wherein the bias insulator is a solder barrier between a cable end side and a connector end side.
17. An inner contact arrangement for a coaxial cable connector, comprising:
an inner contact supported coaxially within a connector bore of the connector by a support insulator;
a plurality of tines extending from a central portion of the inner contact;
a shoulder on an inner surface of the tine(s), the shoulder located within a middle third of a longitudinal length of the tine(s);
the tine(s) angled outward between the shoulder and a cable end of the tine(s);
a bias insulator with a ramp bore;
the bias insulator retained stationary within the connector bore; and
the cable end of the tine(s) swaged inward by the ramp bore.
18. The arrangement of claim 17 , wherein the length of the tine(s) is between 3 and 8 times a radial thickness of the tine(s).
19. The arrangement of claim 17 , wherein a radial thickness of the tine(s) is reduced between the cable end and the shoulder.
