A power adapter for powering portable electronic devices is disclosed. The modifications and enhancements to the power adapter can reduce or eliminate the need for adhesives, flexible circuitry, and/or wiring. The power adapter includes multiple guide rails used to guide a circuit board (carrying components) to electrical springs. The electrical springs provide not only an electrical coupling, but also a mechanical coupling. As a result, wiring and/or adhesives is not required. Additionally, a cap is secured to the enclosure through melting part of the cap by, for example, ultrasonic welding without causing damage to the circuit board, as welding location(s) is/are in locations away from the electrical springs and other sensitive components. The power adapter further includes a connector connected to the circuit board. During assembly, the circuit board can pivot in three dimensions during assembly to align the connector with the cap.

A screw anti-loosening structure is provided including a screw disposed within a screw hole. The screw hole is disposed within a first casing. A screw groove is disposed within a second casing. At least one stub protrudes toward the screw hole of the first casing. The screw anti-loosening structure further includes at least one stub groove disposed within a side surface of a head of the screw. The at least one stub is disposed within the stub groove.

According to one embodiment, in a semiconductor storage device, a conductive cover is provided on a side of the principal surface, and covers at least a part of the memory and the controller. A substrate has a first notched portion and a second notched portion in an outer edge. The conductive cover has a top plate portion, a first side plate portion, a second side plate portion, a first claw portion, and a second claw portion. The first claw portion is extended from a lower end of the first side plate in a direction intersecting with the principal surface. The first claw portion is fitted into the first notched portion. The second claw portion is extended from a lower end of the second side plate in the direction intersecting with the principal surface. The second claw portion is fitted into the second notched portion.

A radar sensor for a vehicular radar sensing system includes a housing structure and at least one printed circuit board (PCB). The housing structure includes a front housing and a rear housing. The PCB is accommodated between the front housing and the rear housing in a cavity established when the front housing and the rear housing are joined together. The rear housing may be joined to the front housing via an intermediate frame disposed between the front housing and the rear housing, with the rear housing secured to the intermediate frame via a plurality of fasteners and with the front housing secured to the intermediate frame via welding.

A heat generating component is mounted on a circuit board housed and fixed in a case including a base and a cover. Heat generated from the circuit board is transferred from a back surface of the circuit board via an insulating sheet to a heat transfer base portion formed on an inner surface of the base. Protruding portions configured to press the circuit board through elastic bodies are formed on an inner surface of the cover. When a peripheral portion of the circuit board is in pressure contact with and sandwiched between base-side and cover-side hold portions, curvature deformation of the peripheral portion of the circuit board occurs in a downward direction. Before start of the curvature deformation, the elastic bodies are brought into abutment against a front surface of the circuit board to suppress a reduction in pressure contact force on the insulating sheet.

The invention relates to a method for forming a laser-welded connection, in which two parts to be joined (11; 11a, 12; 12a) are connected to one another under the effect of a laser beam (1) in a joining region (30; 30a) to form a weld (2), wherein one part to be joined (11; 11a) consists of a material transparent to laser radiation and the other part to be joined (12; 12a) consists of a material absorbent to laser radiation, and wherein the two parts to be joined (11; 11a, 12; 12a) form a receptacle (25; 25a; 25b) for a component (13; 13a; 13b; 14) separate from the parts to be joined (11; 11a, 12; 12a).

A portable data storage device that has a main housing, a data storage module mounted in the main housing, a first protective swivel, and a second protective swivel. The data storage module has a first electrical connector and a second electrical connector. The first protective swivel is U-shaped and has two ends pivotally connected to the main housing. The second protective swivel is U-shaped and has two ends pivotally connected to the first protective swivel. The first protective swivel and the second protective swivel are not removed from the main housing before using the portable data storage device, thus preventing from being loss. The first protective swivel and the second protective swivel cover the first electrical connector and the second electrical connector respectively and protect the first electrical connector and the second electrical connector from being damaged.

An electronic unit includes a first case made of metal; a second case made of metal; a frame made of synthetic resin arranged inside an assembly of the first case and the second case; a relay member made of metal that is separate from the frame and includes a first connection portion electrically connected to the first case, a second connection portion electrically connected to the second case, and a coupling portion coupling the first connection portion and the second connection portion; a first screw that passes through the first case and the first connection portion from the outside of the first case and is fixed to the frame; and a second screw that passes through the second case and the second connection portion from the outside of the second case and is fixed to the frame.

Disclosed are a housing for receiving an electronic device and an electronic system having the same. The electronic system includes a case having lower and upper cases detachably combined with the lower case, a circuit board arranged in an inner space of the case and secured to the lower case such that at least a grounding line and at least a connection line are provided with the circuit board, a plurality of devices arranged on the circuit board such that each device is separated from one another by the grounding line and is connected with one another by the connection line, and at least an electromagnetic shielding member embedded onto the upper case such that the electromagnetic shielding member is in contact with the grounding line around the device to provide a shielding space receiving the device. The device is protected from unexpected electromagnetic waves by the electromagnetic shielding member.
