Electromagnetic interference shielding (EMI) apparatus including a frame with drawn latching features
First Claim
1. A shielding apparatus suitable for use in providing electromagnetic interference shielding for one or more electrical components on a substrate, the shielding apparatus comprising:
- a cover including one or more retention members having one or more cam surfaces and one or more openings;
a frame having a top surface and sidewalls, the frame being partly drawn in construction such that the frame includes;
one or more drawn latching features extending outwardly from the top surface of the frame, the one or more drawn latching features engageable within the one or more openings of the cover to thereby releasably attach the cover to the frame; and
one or more openings along the sidewalls where material was drawn to form the one or more drawn latching features, which openings extend downwardly along the sidewalls from the one or more drawn latching features to a bottom of the frame such that each of the one or more openings along the sidewalls has an open shape;
wherein the one or more drawn latching features contact and slide along the one or more cam surfaces of the one or more retention members of the cover when the cover is positioned over the frame, and wherein sliding contact of the one or more drawn latching features with the one or more cam surfaces causes the one or more retention members to move and allow the one or more drawn latching features to move into the one or more openings of the one or more retention members.

Abstract
Exemplary embodiments are disclosed of shielding apparatus or assemblies having a frame with drawn latching features or portions that are configured for removably attaching a cover to the frame. In an exemplary embodiment, there is a shielding apparatus suitable for use in providing electromagnetic interference shielding for one or more electrical components on a substrate. In this example, the shielding apparatus generally includes a cover and a frame. The cover includes one or more openings. The frame includes a top surface and sidewalls configured to be disposed generally about one or more electrical components on a substrate. The frame is partly drawn in construction such that the frame includes one or more drawn latching features or portions configured to be engaged within the one or more openings of the cover to thereby releasably attach the cover to the frame.

15. A shielding apparatus suitable for use in providing electromagnetic interference shielding for one or more electrical components on a substrate, the shielding apparatus comprising:
-
a cover including an upper surface and retention members extending generally downwardly from the upper surface, the retention members including cam surfaces and openings therein; and a frame having a top surface and sidewalls, the frame being partly drawn in construction such that the top surface includes spaced-apart drawn portions protruding outwardly from the sidewalls that contact and slide along the cam surfaces of the cover'"'"'s retention members when the cover is positioned over the frame to thereby engage within the openings of the cover'"'"'s retention members for removably attaching the cover to the frame, wherein the frame includes openings along the sidewalls where material was drawn to form the spaced-apart drawn portions which openings extend downwardly along the sidewalls from the spaced-apart drawn portions to a bottom of the frame such that each of the openings along the sidewalls has an open shape. - View Dependent Claims (16, 17, 18)

- 19. A method for making a frame of an electromagnetic interference shielding apparatus having a top surface and sidewalls downwardly depending from the top surface, the method comprising drawing a piece of material over a die such that the top surface includes spaced-apart drawn portions protruding outwardly from the sidewalls for sliding engagement within openings of a cover for removably attaching the cover to the frame, whereby the spaced-apart drawn portions are formed solely by drawing only predetermined portions of the piece of material upwardly at locations corresponding to locations of the openings in the cover without cutting the drawn portions and without having to cut or otherwise remove material from the frame, whereby openings are formed along the sidewalls of the frame where material was drawn to form the spaced-apart drawn portions which openings extend downwardly along the sidewalls from the spaced-apart drawn portions to a bottom of the frame such that each of the openings along the sidewalls has an open shape and such that the sidewalls include lower edge portions that are spaced apart and that define the bottom of the frame.
