Mechanical seal between an actuator housing and cover and method for providing a seal between an actuator housing and cover

An assembly, comprising:

• a first component having a protrusion, the protrusion extending about a periphery of the first component;
• a second component having a pair of cantilevered beams formed as a single piece with the second component, the pair of cantilevered beams extending about a periphery of the second component, each of the cantilevered beams being configured for interaction with the protrusion of the first component when the second component is secured to the first component, the pair of cantilevered beams each having an interior surface and an opposite exterior surface, the interior surface of each of the pair of cantilevered beams being in a facing spaced relationship with respect to each other to define a channel that receives the protrusion when the second component is secured to the first component, wherein the opposite exterior surface of each of the pair of cantilevered beams slopes inwardly towards the channel, and each of the pair of cantilevered beams has a distal end where the interior surface and the opposite exterior surface of each of the pair of cantilevered beams terminate, each distal end contacting a corresponding angled surface of the protrusion when the first component is secured to the second component, wherein each of the pair of cantilevered beams must be forced outwardly away from each other on opposite sides of the protrusion prior to each of a plurality of tab portions of the second component being fully received and engaged into a respective opening of a plurality of openings of the first component during a process of securing the first component to the second component, and wherein the assembly is an actuator of a vehicle latch and the first component is a housing of the actuator and the second component is a cover.

A method of providing a mechanical interface between a first component and a second component, comprising:

• forcing a pair of cantilevered beams, located on the second component, outwardly from each other on opposite sides of a protrusion of the first component prior to a tab portion of the second component being fully received and engaged into an opening of the first component to secure the second component to the first component, the pair of cantilevered beams formed as a single piece with the second component and the pair of cantilevered beams extend about a periphery of the second component, each of the cantilevered beams being configured for interaction with the protrusion of the first component when the second component is secured to the first component, each of the pair of cantilevered beams having an interior surface and an opposite exterior surface, the interior surface of each of the pair of cantilevered beams being in a facing spaced relationship with respect to each other to define a channel that receives the protrusion when the second component is secured to the first component, wherein the opposite exterior surface of each of the pair of cantilevered beams slopes inwardly towards the channel, and each of the pair of cantilevered beams has a distal end where the interior surface and the opposite exterior surface of each of the pair of cantilevered beams terminate, each distal end contacting a corresponding angled surface of the protrusion when the first component is secured to the second component, and wherein the first component is a housing of an actuator and the second component is a cover.
