Abstract
A latching assembly includes a hinge defining a slot, the slot having a slot length and a slot width, wherein the slot length is greater than the slot width, and a latching actuator having a housing and a plunger partially disposed in the housing, the plunger configured to translate and rotate relative to the housing, the plunger having a distal end with a plunger end length and a plunger end width, wherein the plunger end length is greater than the plunger end width, the plunger configured to be inserted into the slot. The plunger end length is greater than the slot width and the plunger end length is less than the slot length by a clearance amount.
Claims14
A latching assembly, comprising:
- a hinge defining a slot, the slot having a slot length and a slot width, wherein the slot length is greater than the slot width;
- and
- a latching actuator having a housing and a plunger partially disposed in the housing, the plunger configured to translate and rotate relative to the housing, the plunger having a distal end with a plunger end length and a plunger end width, wherein the plunger end length is greater than the plunger end width, the plunger configured to be inserted into the slot, and
- wherein the plunger end length is greater than the slot width and the plunger end length is less than the slot length by a clearance amount,
- wherein the plunger end length is defined by a first arm and a second arm each disposed at the distal end that extend out from a body of the plunger, and
- wherein the first arm includes a first semi-spherical surface and a first front angled surface and the second arm includes a second semi-spherical surface and a second front angled surface.

An assembly for a fuel/charge port comprising:
- a door;
- a hinge defining a slot, the slot having a slot length and a slot width, wherein the slot length is greater than the slot width, the hinge including a bar disposed overtop the slot to define a locking receptacle;
- and
- a latching actuator having a housing and a plunger partially disposed in the housing, the plunger configured to translate and rotate relative to the housing, the plunger having a first arm and a second arm each disposed at a distal end, the first and second arms defining a plunger end length, wherein the plunger is moveable between a latched position where the first and second arms are disposed in the locking receptacle and are perpendicular to the slot length and an unlatched position where the first and second arms are aligned with the slot length,
- wherein the plunger end length is greater than the slot width and the plunger end length is less than the slot length by a clearance amount,
- wherein the hinge includes a front surface and a back surface, and the back surface includes an angled face surrounding the slot,
- wherein the front surface includes a crown surrounding the slot,
- wherein the door is attached to the front surface of the hinge, and
- wherein the first arm includes a first semi-spherical surface configured to engage the crown of the hinge and a first front angled surface configured to engage the angled face of the hinge, and the second arm includes a second semi-spherical surface configured to engage the crown of the hinge and a second front angled surface configured to engage the angled face of the hinge.

An assembly for a fuel/charge port comprising:
- a hinge having a front surface, a back surface and defining a slot, the slot having a slot length and a slot width, wherein the slot length is greater than the slot width, the hinge including a bar disposed on the front surface over the slot to define a locking receptacle, wherein the back surface includes an angled face surrounding the slot and the front surface includes a crown surrounding the slot;
- a door coupled to the front surface of the hinge;
- and
- a latching actuator having a housing and a plunger partially disposed in the housing, the plunger configured to translate and rotate relative to the housing, the plunger having first and second arms disposed at a distal end, the first and second arms defining a plunger end length, wherein the plunger is moveable between a latched position where the first and second arms are disposed in the locking receptacle and are perpendicular to the slot length and an unlatched position where the first and second arms are aligned with the slot length, wherein the first arm includes a first semi-spherical surface and a first front angled, and the second arm includes a second semi-spherical surface and a second front angled surface, wherein the first and second semi-spherical surfaces are configured to engage the crown of the hinge when in the latched position and the first and second angled front surfaces are configured to engage the angled face of the hinge when the plunger is inserted into the locking receptacle,
- wherein the bar has a curved surface that faces the slot and the distal end of the plunger contacts the curved surface of the bar when disposed through the slot and moving to the latched position, and
- wherein the plunger end length is greater than the slot width and the plunger end length is less than the slot length by a clearance amount.
