Abstract

A connector assembly of a cartridge of an electronic vaping device may be formed by metal in-molding. The connector assembly may include a connector body that is integrally formed. The connector body may include a base portion that is generally cylindrical, a nose portion extending from a first end of the base portion, and at least two slots extending longitudinally through the base portion and on opposing sides of the nose portion. An electrical lead extends through each of the at least two slots.

First claim

We claim:

1. A connector assembly of a cartridge of an electronic vaping device, the connector assembly comprising:
a first connector body including,
a first base portion that is cylindrical,
a nose portion extending from a first end of the first base portion, the nose portion being cylindrical, and the nose portion having a smaller diameter than the first base portion,
at least two slots extending longitudinally through the first base portion and on opposing sides of the nose portion, and
a first orifice extending longitudinally through the first base portion and the nose portion;

at least two electrical leads each including a first end and a second end, the first end of each of the at least two electrical leads extending through a respective one of the at least two slots, at least a portion of the at least two electrical leads are in-molded within the first connector body; and
a second connector body including,
a second base portion that is cylindrical,
a tubular portion extending longitudinally from a second end of the second base portion, and
a second orifice extending through the second base portion and the tubular portion, the second orifice configured to receive a portion of the first base portion of the first connector body and the second end of each of the at least two electrical leads such that the second end of each of the at least two electrical leads abuts an inner surface of the second orifice.

2. The connector assembly of claim 1 , wherein the at least two electrical leads are formed of stainless steel.

3. The connector assembly of claim 1 , wherein the at least two electrical leads have a cross-sectional area sufficient to reduce an electrical resistance of the at least two electrical leads.

4. The connector assembly of claim 1 , further comprising:
a third slot extending longitudinally through the first base portion;
a third electrical lead extending through the third slot;
a fourth slot extending longitudinally through the first base portion; and
a fourth electrical lead extending through the fourth slot.

5. The connector assembly of claim 1 , wherein the first connector body and the second connector body are formed of at least one polymer.

6. The connector assembly of claim 1 , wherein the at least two electrical leads include a U-shaped notch at the second end thereof.

7. The connector assembly of claim 1 , further comprising:
an air inlet in the second base portion of the second connector body, the air inlet in fluid communication with the first orifice in the first connector body.

8. The connector assembly of claim 1 , further comprising:
a connector piece having a cup-shape surrounding the tubular portion of the second connector body, a portion of the connector piece extending through the second orifice, the connector piece defining a third orifice that is longitudinally aligned with the second orifice of the second connector body.

9. The connector assembly of claim 8 , further comprising:
a metal liner between an outer surface of the tubular portion of the second connector body and the connector piece.

10. The connector assembly of claim 1 , wherein the tubular portion has a second end opposite the second base portion, the second end of the tubular portion defines a plurality of orifices, the plurality of orifices surrounding the second orifice.

11. A cartridge of an electronic vaping device, the cartridge comprising:
a housing extending in a longitudinal direction, the housing having a first end and a second end;
an inner tube coaxially positioned in the housing;
a heating element in the housing; and
a connector assembly including,
a first connector body including,
a first base portion that is cylindrical,
a nose portion extending from a first end of the first base portion, the nose portion being cylindrical, the nose portion having a smaller diameter than the first base portion, and the nose portion extending into the inner tube,
at least two slots extending longitudinally through the first base portion and on opposing sides of the nose portion,
a first orifice extending longitudinally through the first base portion and the nose portion, and
at least two electrical leads each including a first end and a second end, the first end of each of the at least two electrical leads extending through a respective one of the at least two slots, at least a portion of the at least two electrical leads are in-molded within the first connector body, and

a second connector body including,
a second base portion that is generally cylindrical,
a tubular portion extending from a second end of the second base portion, and
a second orifice extending through the second base portion and the tubular portion, the second orifice configured to receive a portion of the first base portion of the first connector body and the at least two electrical leads such that the at least two electrical leads abut an inner surface of the second orifice.

12. The connector assembly of claim 11 , wherein the at least two electrical leads are formed of stainless steel.

13. The connector assembly of claim 11 , wherein the at least two electrical leads have a cross-sectional area sufficient to reduce an electrical resistance of the at least two electrical leads.

14. The connector assembly of claim 11 , further comprising:
a third slot extending longitudinally through the first base portion;
a third electrical lead extending through the third slot;
a fourth slot extending longitudinally through the first base portion; and
a fourth electrical lead extending through the fourth slot.

15. The connector assembly of claim 11 , wherein the first connector body and the second connector body are formed of at least one polymer.

16. The connector assembly of claim 11 , wherein the at least two electrical leads include a generally U-shaped notch at the second end thereof.

17. The connector assembly of claim 11 , further comprising:
an air inlet in the second base portion of the second connector body, the air inlet in fluid communication with the first orifice in the first connector body.

18. The connector assembly of claim 11 , further comprising:
a connector piece having a cup-shape surrounding the tubular portion of the second connector body, a portion of the connector piece extending through the second orifice, the connector piece defining a third orifice that is longitudinally aligned with the second orifice of the second connector body.

19. The connector assembly of claim 18 , further comprising:
a metal liner between an outer surface of the tubular portion of the second connector body and the connector piece.

20. The connector assembly of claim 11 , wherein the tubular portion has a second end opposite the second base portion, the second end of the tubular portion defines a plurality of orifices, the plurality of orifices surrounding the second orifice.
