Embodiment Construction

[0021] Example embodiments will now be described more fully with reference to the accompanying drawings.

[0022] Conventional EMI shielded welded metal enclosures may have removable covers for inspection or repair. But its inventors have recognized that there is a lower limit to the overall height of such conventional shields from the base of the board to the top. This limit is due to the size of the attachment features required when the cover attached to the frame begins to approach the limit possible for a given material thickness.

[0023] In recognition of the above, the inventors developed and disclosed herein an exemplary embodiment of a multi-piece shielding apparatus or assembly having a shroud (or cover) and a frame (fence) with pull latch features. As disclosed herein, the frame is at least partially drawn with a latch feature (latch member, protrusion, or latch) located in or extending outward from the top surface of the frame. The pull latch feature of the frame...

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. The invention also relates to a method for manufacturing the frame of the electromagnetic interference shielding apparatus.

Description

technical field [0001] The present disclosure relates generally to electromagnetic shielding apparatus for electronic systems and devices, and more particularly (but not exclusively) to a multi-piece shielding apparatus or assembly having a frame with a drawn latch feature, the The latch feature is configured for removably attaching the cover to the frame. Background technique [0002] This section provides background information related to the present disclosure which is not necessarily prior art. [0003] The operation of electronic devices generates electromagnetic radiation within the electronic circuitry of the device. Such radiation can cause electromagnetic interference (EMI) or radio frequency interference (RFI), which can interfere with the operation of other electronic devices within a certain distance. Without adequate shielding, EMI / RFI interference can cause degradation or complete loss of vital signals, rendering electronic equipment inefficient or inoperable...
