Abstract

A lead includes a lead body extending from a distal end to a proximal end, and at least one conductor disposed within the lead body and extending from the distal end to the proximal end of the lead body. The lead further includes an outer terminal ring, a terminal pin, and an insulative sleeve disposed between the outer terminal ring and the terminal pin, where the insulative sleeve is coupled with the outer terminal ring with a snap-fit connection. A pin latch is disposed on an outer periphery surface of the insulative sleeve, where the pin latch is rotatable about a hinge point.

Claims

1. A method comprising:

disposing a terminal pin within a bore of an insulative sleeve, the insulative sleeve including at least one collapsible pin latch;

disposing the terminal pin and sleeve within an outer terminal ring; and

advancing the insulative sleeve into the outer terminal ring from an uncoupled position to a coupled position, including collapsing the pin latch to a deflected position when the sleeve is in the coupled position.

2. The method as recited in claim 1, further comprising preventing rotation of the insulative sleeve relative to at least one of the terminal pin or the outer terminal ring.

3. The method as recited in claim 2, wherein preventing rotation of the insulative sleeve includes providing anti rotation features along an outer surface of the terminal pin.

4. The method as recited in claim 2, wherein preventing rotation of the insulative sleeve includes forming at least one axial groove along the terminal pin.

5. The method as recited in claim 1, further comprising deflecting an interior surface of the insulative sleeve as the pin latch is deflected toward an exterior surface of the insulative sleeve.

6. The method as recited in claim 1, further comprising snap-fittedly coupling the outer terminal ring with a ring latch of the insulative sleeve.

7. The method as recited in claim 1, further comprising folding the pin latch over a relief groove of the insulative sleeve.

8. The method as recited in claim 1, further comprising compressing the sleeve with an outer surface of the terminal pin.

9. The method as recited in claim 1, further comprising compressing the sleeve with an inner surface of the terminal ring.

10. The method as recited in claim 1, wherein collapsing the pin latch includes collapsing the pin latch between an outer surface of the terminal pin and an inner surface of the terminal ring.

11. The method as recited in claim 7, further comprising providing a second relief groove at an opposite side of the pin latch.

12. The method as recited in claim 1, further comprising advancing tubing over the terminal pin prior to disposing the terminal pin within the insulative sleeve.

13. A method comprising:

disposing a terminal pin within a bore of an insulative sleeve, the insulative sleeve including at least one collapsible pin latch;

disposing the terminal pin and sleeve within an outer terminal ring; and

advancing the outer terminal ring over the terminal pin, including folding the pin latch over a hinge point as the outer terminal ring is advanced over the terminal pin and deflecting an interior surface of the insulative sleeve inward.

14. The method as recited in claim 13, further comprising advancing the outer terminal ring over the terminal pin until a ring latch mates with a recess of the outer terminal ring.

15. The method as recited in claim 13, further comprising capturing a pin flange as the pin latch is folded over the hinge point.

16. The method as recited in claim 13, further comprising advancing tubing over the terminal pin prior to disposing the terminal pin within the insulative sleeve.

17. The method as recited in claim 13, further comprising providing a second relief groove at an opposite side of the pin latch.

18. The method as recited in claim 13, further comprising advancing tubing over the terminal pin prior to disposing the terminal pin within the insulative sleeve.

19. The method as recited in claim 13, wherein collapsing the pin latch includes collapsing the pin latch between an outer surface of the terminal pin and an inner surface of the terminal ring.

20. A method comprising:

disposing a terminal pin within a bore of an insulative sleeve, the insulative sleeve including at least one collapsible pin latch;

disposing the terminal pin and sleeve within an outer terminal ring; and

advancing the insulative sleeve into the outer terminal ring from an uncoupled position to a coupled position, including collapsing the pin latch to a deflected position when the sleeve is in the coupled position, and snap-fittedly coupling the outer terminal ring with a ring latch of the insulative sleeve; and

;

preventing rotation of the insulative sleeve relative to at least one of the terminal pin or the outer terminal ring.

21. The method as recited in claim 20, further comprising folding the pin latch over a relief groove of the insulative sleeve.

22. The method as recited in claim 20, further comprising compressing the sleeve with an inner surface of the terminal ring.

23. The method as recited in claim 20, further comprising advancing tubing over the terminal pin prior to disposing the terminal pin within the insulative sleeve.

24. The method as recited in claim 20, wherein disposing the terminal pin within the bore of the insulative sleeve includes disposing the terminal pin within a tapered interior surface of the insulative sleeve.
