A lid (5) has, on a lid surface (5a) facing the opening (4a), a second protrusion (5b) fitted to a second notch (3b) of the substrate (3), a second rib (5c), and a third rib (5d), the second and third ribs supporting a second end of the substrate (3) by sandwiching the second end, and has, at an outer periphery, hooks (5g) for fixing the lid (5) to the box (4) by being fitted to the holes (4n) of the box (4). The hooks (5g) each have an inclined surface (5j) that allows the lid (5) to move by a specified amount in a direction in which the lid (5) comes off from the box (4).

An object is to provide a technique capable of increasing waterproofness of an electronic unit. An electronic unit includes: a case including an opening; a circuit board housed in the case through the opening; and a cover attached to the opening, wherein a protruding portion is provided on at least one side wall of the case, and the protruding portion includes a step that causes an opening side portion of the side wall to protrude further outward relative to a rear side portion of the side wall, and is provided so as to extend along the periphery of the opening.

Provided is an electronic pen including an electronic pen body portion, an electronic pen housing being a cylindrical body housing the electronic pen body portion, a connector portion including a connector substrate, and a terminal portion including a base portion raised from the connector substrate in a direction crossing an axial direction and a contact portion extended to a back end side from a position separated from the connector substrate on a back end surface of the base portion, and a connector housing being a cylindrical body housing the connector portion and connected to a back end side of the electronic pen housing. A cross section of the connector housing in a direction orthogonal to the axial direction is substantially triangular. An axial center of the connector substrate coincides with an axial center of the electronic pen body portion when the connector housing is attached to the electronic pen housing.

An electrical junction box is provided that can suppress a failure occurring due to a connector being exposed to external stress. An electrical junction box includes a substrate on which the connector is mounted, a case in which an opening portion is formed and the substrate is accommodated, and a cover that is attached to the opening portion and in which an insertion hole, into which the connector is to be inserted, is formed in a penetrating manner. The cover includes protruding portions at positions on sides of the connector, the protruding portions protruding forward of a leading end of the connector.

An electronics thermal conduction package is provided. The package may include a housing and an interior space, or envelope, configured to receive a printed circuit board assembly (PCBA) with one or more microprocessors or other heat generating elements. The package can be elastically deformed to open a dimension of the envelope, or receiving cavity, such that a complete PCBA can be inserted inside the interior space of the package. Once inserted, the package may be returned to its undeformed, or substantially undeformed, state such that surfaces in the interior space of the package contact one or more of the heat generating elements on the PCBA creating a conductive thermal path from the heat generating elements to the housing of the package.

A radio frequency sensor module adapted for mounting a vehicle exhaust system structure. A bracket on the module includes a first mounting ear defining a first through aperture. A printed circuit board is coupled to the bracket. A cover defines an opening and an interior cavity in communication with the opening. The bracket and the cover are coupled together in a relationship with the printed circuit board extending through the opening in the cover and into the interior cavity of the cover and the first and second mounting ears in an abutting and overlying relationship. A mounting bolt extends through the respective first and second through apertures in the respective first and second mounting ears for securing the radio frequency module to the housing of a vehicle exhaust system.

A proximity sensor in which generation of voids in a resin sealing portion sealing an inside of a housing can be suppressed and thus a yield is improved. The proximity sensor includes a housing, a detection coil, a circuit board and a resin sealing portion. The circuit board is accommodated in the housing to partition an internal space of the housing, and the resin sealing portion covers at least a part of the circuit board by filling the internal space of the housing and thus seals a covered portion of the circuit board. A resin injection port configured to inject a liquid resin forming the resin sealing portion by curing the liquid resin is provided in the housing, and a cutout portion having a notch shape or an opening shape is provided in the circuit board to include at least a part of a portion facing the resin injection port.

An electronic component module includes a housing and a substrate which is configured to be housed in the housing. The substrate has a substrate side part which extends straight in a housing direction to the housing and which is configured to be guided to the housing when the substrate is housed. The housing has a substrate guide part which is configured to guide the substrate side part when the substrate is housed, a housing side wall on which the substrate guide part is formed, and a locked part which is formed to be continuous to an outer surface of the housing side wall and which is locked to an attachment destination.

A portable electronic device includes a stylus including a pen-shaped casing structure, a support structure, a rear circuit board, a function assembly, a pen head structure and a power supply. The support structure is disposed in the casing structure. The rear circuit board is positioned on the support structure. The function assembly is disposed on the support structure. The head structure is partially disposed out of the casing structure. The power supply is electrically connected to the rear circuit board. The function assembly includes first, second and third conductive members, first and second movable members, and a button body. When the button body is pressed to drive the first and second movable members to move simultaneously, the first movable member simultaneously electrically contacts the first and second conductive members, so the first and the second conductive members are electrically connected with each other through the first movable member.

An electronic device includes: a casing; and an electronic circuit board housed within the casing. The electronic device further includes a protector which is provided on a surface of the electronic circuit board that faces the casing. The height of the protector is larger than the height of an electronic component mounted on the surface of the electronic circuit board that faces the casing. In a state that the electronic circuit board is housed within the casing, the protector abuts on a surface of the casing that faces the electronic circuit board.
