In an example embodiment a power adapter includes a shell, a plug assembly, an electronic assembly and a protective shield, wherein the plug assembly comprises a plug and a connector electrically connected to the plug. The electronic assembly comprises a transformer and an electronic element; and the protective shield is located inside a receiving cavity and encloses a protective cavity together with a cavity wall of the receiving cavity, the connector is located inside the protective cavity, the electronic assembly is located outside the protective cavity, and the protective shield is a protective shield made of an insulating material. The power adapter reduces the influence of strong electrical interference generated by the connector on the electronic assembly, so that the space in the receiving cavity can be fully utilized, thereby realizing the small volume setting of the shell.

A new and improved intrinsically safe barrier (“ISB”) provides advantages in connection with installation of field equipment in hazardous areas including Division 2/Zone 2 areas. In one embodiment the new ISB provides a pluggable/unpluggable ISB for use with a receiving terminal base adapted for individual field mounting and alternatively for use with a circuit mount terminal base to permit direct mounting of ISB on circuit boards. A highly effective heat sink design and potting material allows for heat dissipation to allow the ISB to serve a wider range of applications.

An improved electronic control unit for a motor vehicle comprises a printed circuit board in a one-piece bucket-style housing. The printed circuit board includes a heat-producing electrical component, and the housing includes a heat sink. During assembly of the electronic control unit, the printed circuit board is slid into the housing through an opening in the housing and along a pair of side rails. At the end of the side rails opposite the opening, there is a ramp that lifts the PCB towards the top wall of the housing, thus allowing the electrical component to thermally couple with the heat sink.

Disclosed is an electronic control device using a connector-integrated housing and a bendable printed circuit board. The electronic control device according to an exemplary embodiment of the present invention includes: a housing including a first body formed with an opening at one side and a second body connected with the first body through a hinge part, the opening being closed according to a rotation of the second body; a printed circuit board including a first substrate part and a second substrate part connected through a flexible connection part; and a connector coupled to the second body, in which the first substrate part is inserted into the first body, and the second substrate part is coupled with the connector to be connected with the second body.

An electronic control unit includes a control board, a battery pack, and a housing that accommodates the control board and the battery pack. The electronic control unit further includes a battery holder that has a bent shape and includes a bottom surface along a longitudinal direction of the battery pack, the battery holder clamping a main body of the battery pack, and a fixing frame that includes a juxtaposing and mounting part on which a plate surface of the control board and the bottom surface of the battery holder are mounted in a state of being adjacent to each other with a boundary line along the longitudinal direction therebetween, the control board and the battery holder being fixed to the juxtaposing and mounting part. The housing includes an opening portion into which the juxtaposing and mounting part of the fixing frame is inserted, and a back side holding portion that holds the juxtaposing and mounting part at an inner back side of the housing opposed to the opening portion. The fixing frame further includes a sealing front part that closes the opening portion of the housing with the juxtaposing and mounting part accommodated in the housing and that is fixed to the housing in a state of closing the opening portion.

A pen input device is provided, including a housing including a front opening and a rear opening; a pen input generator including a pen tip disposed in the front opening, the pen input generator generating a position signal and a pen pressure signal of the pen input device; a battery; a PCB; a support on which at least a part of the pen input generator, the battery, and the PCB are disposed; a conductive member electrically connecting the PCB and the battery; a buffer disposed in the rear opening; and a polymer that fills in an inner space of the housing. The support includes a support plate extended in a direction toward the rear opening from the front opening of the housing, and a first partition, a second partition, and a third partition, which protrude from the support plate and are sequentially spaced.

An engagement structure includes a cover having an opening portion, a block member inserted into the opening portion, an engagement mechanism configured to engage the block member with the opening portion, and an engagement stabilization mechanism configured to stabilize an engagement state of the engagement mechanism. The engagement stabilization mechanism includes a first stabilization mechanism and a second stabilization mechanism. The first stabilization mechanism permits excessive insertion due to backlash that occurs in the engagement mechanism and to restore the excessive insertion after the block member is engaged with the opening portion. The second stabilization mechanism performs a slide engagement between the block member and the opening portion and to restrict a wall inner surface of the cover from moving away from an outer surface of a side portion of the block member after the slide engagement is completed.
