FUEL TANK LID AND FUEL PUMP MODULE HAVING THE SAME

摘要

A fuel tank lid includes a lid part closing an opening of a fuel tank, and an internal terminal electrically connecting a pump provided inside the fuel tank with a drive circuit driving the pump. The lid part includes an inserted part inserted into the opening, a storage part located outside the fuel tank and storing the drive circuit in a hollow space of the storage part, and a connection part located outside the fuel tank and connecting the inserted part and the storage part. The fuel tank lid further includes a discharge part discharging a fuel vapor that tries to travel along an interface between the internal terminal and the lid part and enter the hollow space, to an external atmosphere, and a protection part covering the portion exposed from the lid part by the presence of the discharge part to protect the portion from a liquid.

主权项

1. A fuel tank lid comprising:
a lid part closing an opening of a fuel tank; and an internal terminal electrically connecting a pump provided inside the fuel tank with a drive circuit driving the pump, wherein the lid part includes
an inserted part inserted into the opening,a storage part located outside the fuel tank and storing the drive circuit in a hollow space of the storage part, anda connection part located outside the fuel tank and connecting the inserted part and the storage part, and the internal terminal has a central portion, a first end, and a second end, the central portion being covered and protected by the inserted part, the connection part, and the storage part that are made of a resin material, the first end being connected to the pump inside the fuel tank, the second end being connected to the drive circuit inside the hollow space of the storage part, the fuel tank lid further comprising a discharge part discharging a fuel vapor that tries to travel along an interface between the internal terminal and the lid part and enter the hollow space of the storage part, to an external atmosphere, the discharge part being formed in the connection part where thickness is locally reduced such that a portion of the central portion of the internal terminal is exposed from the lid part for discharging; and the fuel tank lid further comprising a protection part covering the portion of the central portion of the internal terminal exposed from the lid part by the presence of the discharge part to protect the portion from a liquid.
