This electrical equipment device includes a housing storing an electronic component in an internal space thereof, and includes a vent hole through which an outside and an inside of the housing communicate with each other. The vent hole is formed inside a wall of the housing. One end side of the vent hole has a first opening communicating with the outside of the housing on a gravity-direction lower side. Another end side of the vent hole has a second opening communicating with the inside of the housing on a gravity-direction upper side. At the second opening, a waterproof vent film is provided to close the second opening.

The present technology relates to an air reservoir for an enclosure where, upon submersion in water, the pressure differential between the water and the enclosure displaces air from the air reservoir into the enclosure to reduce the pressure differential.

A porous polytetrafluoroethylene (PTFE) membrane of the present disclosure is a membrane having an average fibril length of 50 μm or more, having an average node length 5 or more times larger than the average fibril length, and having an average node area ratio of 5% or less. The porous PTFE membrane of the present disclosure, when attached as a waterproof air-permeable membrane to a housing of an electrical component or electrical device, allows water vapor residing inside the housing to be quickly discharged out of the housing.

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 pump assembly includes an electric motor with a printed circuit board carrying a controller, a pump driven by the electric motor, a housing surrounding the printed circuit board, and a connector attached on the outside of the housing by a flange. The connector covers an opening of the housing and includes contacts for direct electrical contact with the printed circuit board which passes through the opening of the housing. The connector includes a pressure compensator in the flange.

A pump assembly includes an electric motor with a printed circuit board with a controller, a pump driven by the electric motor, a housing surrounding the printed circuit board, and a connector which is fastened on an outside of the housing by a flange, which covers an opening of the housing, and which includes contacts directly electrically contacting the printed circuit board. The contacts pass through the opening of the housing. The connector includes a main housing in which the contacts extend and which adjoins the flange. The connector includes a pressure compensator which is in the main housing.

A pump unit assembly includes an electric motor with a printed circuit board carrying a controller, a pump driven by the electric motor, a housing surrounding the printed circuit board, and a plug connector which is fixed to an outside of the housing by a flange. The plug connector covers an opening of the housing and includes contacts directly electrically contacting the printed circuit board and passing through the opening of the housing. The connector includes a pressure compensator including a sintered filter to vent the housing.

A portable electronic device can include a housing at least partially defining an internal volume. The device can include a venting module including a membrane, a porous member, and a support structure. The membrane and porous member can define a fluid path extending a width of the porous member and placing the internal volume in fluid communication with an ambient environment adjacent the housing. The support structure can be coupled to the porous member.

A pressure equalization element for equalizing the pressure of an interior space of a housing, in particular of an electric, motor or gearing housing, of a tank or the like, with respect to an outer side, is specified. The pressure equalization element includes a hole which is formed in a wall of the housing, a diaphragm which is attached on the interior space side in the region of the hole and which closes off the hole with respect to the outer side of the housing in water-tight but air-permeable fashion, and a holding structure which is formed on the housing in the region of the hole and which serves for accommodating an impact guard. The impact guard is connectable, on the outer side of the housing, to the holding structure and protects the diaphragm against mechanical action. A housing having the pressure equalization element is also specified.

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.
