  • Patent number: 12327939
    Abstract: A connector of the present invention includes a fixed housing, a movable housing, a plurality of terminals, and a metal movement restricting member to be attached to the fixed housing. The movable housing includes a main body portion for insertion in a loose fit state into an insertion hole of the fixed housing, and a protrusion portion projecting from the main body portion. In the state where the main body portion has been inserted into the insertion hole, the protrusion portion projects from the main body portion along a perpendicular direction that is perpendicular to both the insertion direction and the width direction. When the main body portion becomes displaced in a direction opposite to the insertion direction, the movement restricting member restricts the amount of displacement of the movable housing by abutting against the protrusion portion.

  • Publication number: 20200016975
    Abstract: The present disclosure is directed to a fuel tank with an internal support structure and external reinforcements to minimize deformations due to pressure variations, such as may arise from diurnal temperature variations. Uncontrolled contraction of fuel tanks may result in undesirable reductions of tank volume, and uncontrolled expansion of fuel tanks may result in unwanted collision of fuel tanks with other vehicle components. The fuel tank of the present disclosure may find utility in applications where regular venting of fuel tanks is not practical, such as in hybrid vehicles.
