Embodiments of the present application relate to a power supply device, including a housing, a circuit board and a connecting assembly. The housing defines an accommodation space, and includes: a housing positioning component, a first opening, and a second opening. The housing positioning component is disposed in the accommodation space. The circuit board is disposed in the accommodation space, and includes: a circuit board positioning component, a power input port, and a power output port. The power input port is disposed corresponding to the first opening. The power output port is disposed corresponding to the second opening, and electrically connected to the power output port. The connecting assembly is configured to connect the housing positioning component and the circuit board positioning component, and position the circuit board in the accommodation space of the housing.

An electromagnetic interference (EMI) shield is disclosed. The EMI shield includes an electrically conductive sleeve configured to surround a connector. The electrically conductive sleeve includes a restriction configured to contact a metal perimeter of the connector and includes a connection member configured to be electrically coupled to a circuit board.

A cabinet enclosure for mounting to a vehicle and providing an inner cavity isolated from a surrounding environment. The cabinet enclosure includes a removable module including a frame and a plurality of mounts on the frame for receiving an electrical component. A housing defines the inner cavity and includes a plurality of predefined mounting locations within the inner cavity configured to receive the removable module. The housing is configured to protect the inner cavity from exposure to moisture, heat, vibration and/or electromagnetic forces. An interface element secures the housing to a vehicle.

An electromagnetic wave absorber includes: a first layer having a first enclosing layer that encloses an electromagnetic wave radiator, and a first metal film formed on the first enclosing layer.

The present disclosure provides a housing assembly, and the housing assembly is applied to an electronic device. The housing assembly includes a first part and a second part. The first part includes at least one opening. The second part includes at least one mesh area. The mesh area deformably connects to the first part, and covers the opening.

A shell structure includes a shell and a shielding cover. The shell has an accommodating space, the accommodating space has an inner wall, and the inner wall has a first buckling portion. The shielding cover is arranged in the accommodating space, the shielding cover has an outer wall, the outer wall corresponds to the inner wall, and the outer wall has a second buckling portion corresponding to the first buckling portion. The first buckling portion and the second buckling portion are buckled with each other to limit relative degrees of freedom of the shell and the shielding cover.

At least one shielding layer made of conductive material is formed on a body of a magnetic device to prevent magnetic fields from leaking to the outside of the magnetic device so as to reduce EMI and the size of the magnetic device.

An EMP-resistant (electromagnetic pulse-resistant) case for portable electronic devices is provided. The case includes a conductive external housing configured to enclose the electronic device. The housing includes a lower housing having a continuous connection surface. The housing also includes an upper housing having a continuous connection surface. The lower and upper housing are configured to releasably engage at the continuous connection surface. The housing includes a conductive gasket positioned at the continuous connection surface between the upper and lower housing. The case also includes a first insulative layer at least partially covering the inside surface of the upper and lower housing.

According to various embodiments of the disclosure, an electronic device may include: a housing, a rollable display, a shielding case disposed inside the housing and surrounding at least a part of the rollable display, and including a first opening accommodating the rollable display, and a first antenna structure including at least one antenna disposed in an area outside the shielding case.
