Abstract
An improved an end cap assembly for a fuel pump is provided. The end cap assembly includes first and second brush caps herein that are overmolded onto first and second shunt wires to ensure a fluid-tight seal around the shunt wires without requiring heat staking, sonic welding, or melt flowing the end cap to the shunt wires. The brush caps are cone-shaped and include a snap-fit feature that retains the brush caps in place when the endcap assembly is transported prior to being assembled to a fuel pump body.
Claims16
An end cap assembly for a fuel pump, the end cap assembly comprising:
- an end cap including first and second elongated openings extending entirely through the end cap, the first and second elongated openings being laterally spaced apart from each other;
- a positive terminal protruding from the first elongated opening and a negative terminal protruding from the second elongated opening, the positive terminal comprising a free end of a first shunt wire, and the negative electrode comprising a free end of a second shunt wire;
- and
- a first brush cap overmolded onto the first shunt wire and a second brush cap overmolded onto the second shunt wire, the first and second brush caps each comprising a conical plug having an annular lip at an uppermost portion thereof.
An end cap assembly for a fuel pump, the end cap assembly comprising:
- an end cap including first and second elongated openings extending entirely through the end cap, the first and second elongated openings being laterally spaced apart from each other;
- a first power lead protruding from the first elongated opening and a second power lead protruding from the second elongated opening, the first power lead being electrically connected to a first shunt wire, and the second power lead being electrically connected to a second shunt wire;
- and
- a first brush cap overmolded onto the first shunt wire and a second brush cap overmolded onto the second shunt wire, the first and second brush caps each comprising a conical plug having an annular lip at an uppermost portion thereof.
