Abstract

Claims (37)

1. A glow plug connector comprising:

a glow plug terminal;

a first retainer flange and a second retainer flange;

a retainer disposed between the first retainer flange and the second retainer flange, wherein the retainer is capable of compressing to fit within a passage of a rocker carrier and capable of subsequently expanding to prevent the glow plug connector from being dislodged from the rocker carrier.

2. The glow plug connector of claim 1 , wherein the retainer is comprised of at least one retention arm including an outer member disposed at an angle from an inner member, wherein the at least one retention arm is compressible.

3. The glow plug connector of claim 1 , wherein the retainer is comprised of an expandable spring having a first end and a second end, and wherein a first retention arm is disposed at the first end and a second retention arm is disposed at the second end.

4. The glow plug connector of claim 1 , wherein the retainer is comprised of an expandable spring having a curved section, a first end, and a second end, wherein the curved section comprises a partial ring section and a u-shaped section, and wherein a first retention arm is disposed at the first end and a second retention arm is disposed at a second end.

5. The glow plug connector of claim 1 , further comprising an installation tool groove disposed adjacent to an installation flange.

6. The glow plug connector of claim 1 , further comprising an overmold disposed adjacent to the first retainer flange and the second retainer flange such that the retainer is secured in a groove between the first retainer flange, the second retainer flange, and the overmold.

7. The glow plug connector of claim 1 , further comprising a stopper capable of compressing within an opening of a rocker carrier.

8. The glow plug connector of claim 1 , further comprising:

a first seal flange and a second seal flange separated by a seal groove;

a seal disposed in the seal groove.

9. An apparatus comprising:

an electrical terminal;

a first retainer flange and a second retainer flange;

a retainer disposed between the first retainer flange and the second retainer flange, wherein the retainer is capable of compressing to fit within a passage of an internal combustion engine and capable of subsequently expanding to prevent the apparatus from being dislodged from the internal combustion engine;

wherein the retainer comprises a first compressible retention arm disposed at a first end of a curved section that comprises a partially circular segment at the first end and a u-shaped section at a second end the curved section, and wherein a second compressible retention arm is disposed at the second end the curved section such that compression of the first compressible retention arm and the second compressible retention arm compresses the curved section.

10. The apparatus of claim 9 , wherein the retainer is comprised of at least one retention arm including an outer member disposed at an angle from an inner member, wherein the at least one retention arm is compressible.

11. The apparatus of claim 9 , further comprising an installation tool groove disposed adjacent to an installation flange.

12. The apparatus of claim 9 , further comprising an overmold disposed adjacent to the first retainer flange and the second retainer flange such that the retainer is secured in a groove between the first retainer flange, the second retainer flange, and the overmold.

13. The apparatus of claim 9 , further comprising a stopper capable of compressing within an opening of a rocker carrier.

14. The glow plug connector of claim 9 , further comprising:

a first seal flange and a second seal flange separated by a seal groove;

a seal disposed in the seal groove.

15. A retainer comprising:

an expandable spring comprising a partially circular segment adjacent to a u-shaped section, wherein the partially circular segment is capable of surrounding a part of a connector;

a first compressible retention arm disposed at a first end of the expandable spring;

a second compressible retention arm disposed at a second end of the expandable spring;

wherein bringing the first compressible retention arm and the second compressible retention arm together compresses the expandable spring;

wherein driving the first compressible retention arm and the second compressible retention arm apart causes the expandable spring to expand.

16. The retainer of claim 15 , wherein the retainer is comprised of at least one retention arm including an outer member disposed at an angle from an inner member, wherein the at least one retention arm is compressible.

17. A retainer comprising:

an expandable spring having a curved section capable of being disposed within a groove of a connector and having a first end and a second end;

a first flexible retention arm, disposed at the first end and oriented substantially in a plane perpendicular to a plane in which the expandable spring is disposed, having an inner member disposed at a first angle outwardly from the expandable spring and an outer member disposed at a second angle inwardly toward the expandable spring, such that the inner member and the outer member form an elbow.

18. The retainer of claim 17 , further comprising a second flexible retention arm, disposed at the second end and oriented substantially in the plane perpendicular to the plane in which the expandable spring is disposed, having an inner member disposed at a third angle outwardly from the expandable spring and an outer member disposed at a fourth angle inwardly toward the expandable spring, such that the inner member and the outer member form an elbow.

19. The retainer of claim 17 , wherein the expandable spring comprises two or more at least partial loops.
