    摘要： A shield can for an electronic eyewear device is described that reduces RF signals emanating from the electronic eyewear device. The shield can is attached to a ground plate of the electronic eyewear device using leaf springs on a side of the shield can. The leaf springs do not add to the stack-up thickness of the shield can assembly and provide a balanced force against the ground plate. The shield can is attached to a printed circuit board and encompasses radio frequency (RF) electronic components to prevent RF signals emanating from the RF electronic components. The leaf springs have a pair of fingers providing the balanced mechanical point force. A conductive pressure sensitive adhesive is also provided to secure a top surface of the shield can to the ground plate along with a thermal paste.

    摘要： According to various aspects, exemplary embodiments are disclosed of board level shields. In an exemplary embodiment, a board level shield (BLS) includes a fence and a lid. The fence is solderable to a printed circuit board (PCB). When the lid is engaged to the fence that has been soldered to the PCB, the BLS provides substantial electromagnetic interference (EMI) shielding protection to the components covered by the BLS. The lid may be constructed of a frame and a cover. The cover may be a film or foil. The lid may attach to the fence via a one way directional latching mechanism, which may be enhanced by the use of one or more interior downward tabs on the lid that meet one or more inward protrusions from the fence to create pressure on the lid and fence.

    摘要： A protective shell or shield for an electronic facility includes a receptacle having a chamber formed by a peripheral wall, the peripheral wall of the receptacle includes an engaging member formed in an upper portion of the peripheral wall. The receptacle includes a radio frequency element extended outwardly from the peripheral wall and having an outer thread. The receptacle includes a number of rounded corner areas, and includes a peripheral shoulder formed in an outer peripheral portion of the peripheral wall. The engaging member is a peripheral recess formed in the upper portion of the peripheral wall. A cover includes a plate for engaging onto the peripheral wall for shielding the chamber of the receptacle.
