A shield assembly includes a closing structure configured to be disposed over an opening of an enclosure. The closing structure includes an inner surface configured to face an inside of the enclosure when the closing structure is closed and a finger bracket structure mounted on the inner surface, the finger bracket structure having a bracket and one or more finger gaskets coupled to the bracket. An electromagnetic interference (EMI) shielded gasket disposed along a portion of the opening of the enclosure shields an edge of the opening of the enclosure or a radio frequency (RF) fence bracket coupled to a frame disposed around the opening of the enclosure creates a narrow path between the frame and the closing structure, the narrow path attenuating RF signals passing through the narrow path and shielding an edge of the opening of the enclosure.

Supply station with door shield

A door assembly is described. The door assembly includes a door structure that is mounted over an opening of an enclosure. The door structure includes a body that includes a first surface and a second surface opposite to the first surface. The first surface may face an inside of the enclosure when the door structure is closed. The door structure includes a number of finger bracket structures mounted on the first surface. Each one of the finger bracket structures includes a bracket and one or more finger gaskets coupled to the bracket. The finger gaskets of the finger bracket structures may contact enclosure brackets mounted around an edge of the opening of the enclosure when the door structure is closed. A combination of the finger gaskets in contact with enclosure brackets may create an electromagnetic interference (EMI) shield at the edge of the opening of the enclosure.

An electronics enclosure is disclosed that provides passive cooling of electronic components while reducing electromagnetic interference (EMI) emissions. The electronics enclosure includes an electronics assembly with at least one electronic component and a heat sink coupled to the electronics assembly. The heat sink has a base portion configured to thermally couple to the at least one electronic component when the heat sink is coupled to the electronic assembly. The electronics enclosure also includes a conductive enclosure forming an enclosed volume around the electronics assembly. The enclosure has a first opening configured to fit around the heat sink and at least one second opening. All non-conductive passages from the volume to the external environment have at least one cross-sectional opening having a continuous conductive perimeter with a maximum linear length within the opening of less than one quarter wavelength of a determined maximum shielding frequency.

Passive cooling and EMI shielding system

A modular electronics enclosure for reducing electromagnetic interference (EMI) is disclosed. The electronics assembly includes a first electronic component having an output, a second electronic component having an input with an input impedance, and a circuit matching element having an input coupled to the output of the first electronic component and an output coupled to the input of the second electronic component. The output of the circuit matching element is configured to provide an output impedance that matches the input impedance of the second electronic component. The electronics assembly also includes a conductive surface that forms a volume that encloses the first electronic component and the circuit matching element. All non-conductive passages from the volume to the external environment have at least one cross-sectional opening having a continuous conductive perimeter with a maximum linear length within the opening of less than one quarter wavelength of a maximum shielding frequency.
