An electronics unit includes a housing, the housing having a base portion with a post member extending from the base portion. The post member has a through-hole defined through the post member. A printed circuit board is connected to the housing at a plurality of connection points. The printed circuit board includes one or more electric or electronic components disposed thereon and has an aperture. The post member is disposed through the aperture of the printed circuit board. A distal end portion of the post member is larger than a diameter of the aperture so as to fix the printed circuit board to the housing, forming one of the connection points.

A structural support that can be used as a truss girder bridge crane, or the like. The support includes one or more rows 13 of segments 15, that are arranged in side by side relation along the length of the support. Each row 13 has extending there through at least one tensioning element 14 which is anchored at opposite ends of the row and is pretensioned with respect to the row in order to hold the segments of the row together. A support preferably includes one row 13 of segments 15 in a lower chord 11 of the support and another row 13 of segments in an upper chord of the support. Vertical framework is mounted between the chords with ends secured adjacent the segments 15 by the tensioning element. The individual segments and the tensioning elements may be directed to a construction site at the location of use and assembled into rows and the appropriate structural construction.

To make it possible to enhance waterproofness of a vent hole when an electronic controller is mounted on an automobile. The electronic controller includes a waterproof case that accommodates a printed circuit board with electronic parts mounted thereon, and a connector that electrically connects the printed circuit board and an external apparatus to each other, the electronic controller being mounted on the automobile in a posture having the connector directed downward. The waterproof case has an inclined surface that is smaller as the distance from a bottom surface is more on the connector side, and the inclined surface is formed with a vent hole that is closed with the breathing filter.

A connector (1) is mounted on a case (12) including an internal space (120) accommodating an electronic board (11). The connector (1) includes first terminals (3), a first core (4), second terminals (5), a second core (6), a housing (7) and a ventilation passage (8). The ventilation passage (8) allows the internal space (120) of the case (12) to communicate with outside air. At least a part of the ventilation passage (8) is constituted by a groove (40) formed in at least one of mutually overlapping surfaces (411, 611) of the first core (4) and the second core (6). An outer vent (81) of the ventilation passage (8) is formed at a position closer to the case (12) than the receptacle (71) in a Z direction.

An electronic device is provided. The electronic device includes a housing including an opening, a first cover disposed in the housing to close the opening and includes a first surface facing the outside and a second surface facing an internal space of the housing, at least one air vent formed from the first surface to the second surface in a region of the first cover to connect the outside of the electronic device to the internal space and includes a first space formed to have a specified depth in a direction starting from the first surface to the second surface, and a second space formed to have a specified depth in a direction starting from the second surface to the first surface, wherein the first space and the second space are connected, and a breathable waterproof member disposed to close the second space in the second surface.

A biological device that includes a case, an electronic unit, a gas-liquid separator, and an insulating sheet. The case is wearable on a body. The electronic unit is in an internal space of the case. The gas-liquid separator is attached to the case. The insulating sheet is attached to the case. The case has a communicating hole that connects the internal space and an external space of the case along a first direction. The gas-liquid separator and the insulating sheet are disposed apart from each other in the first direction. The gas-liquid separator, the electronic unit, and the insulating sheet overlap each other in a plan view of the biological device in the first direction.

A computing device includes a housing having a plurality of apertures therein, an active cooling system, and at least one of a plurality of membranes or a plurality of valves. The membranes and/or valves are coupled with the apertures. Each of the membranes is watertight and gas breathable. The valves are configured to prevent entry of water through the apertures. The active cooling system is in the housing. When activated, the active cooling system drives a gas through a membrane but does not drive water through the membrane.

A housing is disclosed. In an embodiment a housing includes a housing opening, a pressure-compensating element mounted on an inner side of the housing opening, a protective wall mounted on an outer side of the housing opening surrounding the housing opening and a bridge arranged over the outer side of the housing opening and protruding beyond the housing opening, wherein the bridge is shaped and arranged such that a projection of the bridge at least partially covers the housing opening.

A waterproof structure formed at a ventilation opening 11 provided in the top surface of a housing 10 in electronic equipment has a first filter 61 attached to the ventilation opening 11 with an inclination along a depth direction D of the housing 10. The first filter 61 is configured from a hydrophobic, water-repellent, and breathable hydromesh layer.
