An electronic unit includes an electrolytic capacitor, a covering resin layer, and electronic components. The electrolytic capacitor is on an upper surface of an insulating substrate. The covering resin layer covers the upper surface of the insulating substrate and the electronic components. Part of the covering resin layer serves as an electrolytic capacitor covering portion. The electrolytic capacitor covering portion includes an outer peripheral covering portion that covers an outer peripheral surface of the electrolytic capacitor and a top covering portion that covers a top portion of the electrolytic capacitor. A thin wall groove is formed in the top covering portion. The outer peripheral covering portion extends upward beyond the top covering portion by a height h. The top covering portion easily breaks at the thin wall groove so that an explosion-proof valve easily operates. A region corresponding to the height h creates an operating space of the explosion-proof valve.

A protection device including a first housing, a second housing, a power component, a protective cover and a circuit board is provided. The second housing and the first housing are assembled to each other to define an internal space. The power component is disposed on the second housing and located in the internal space. The protective cover covers the power component and is located in the internal space. The circuit board is disposed in the internal space, and the protective cover is located between the circuit board and the power component. At least one pin of the power component protrudes beyond the circuit board through the protective cover and the circuit board.

Pressure-isolating bulkhead structures with integrated selective electronic switches circuitry are provided. The pressure-isolating bulkhead structure may be a single unit having the integrated electronic switch circuitry, as well as an electrical connector that includes at least one of a wire and a pin contact. Such integrated selective electronic switch circuitry may be fashioned within a self-contained, inner pressure-isolating enclosure body. Such inner pressure-isolating enclosure body may be produced about the selective electronic switch circuitry such that the inner pressure-isolating enclosure body and switch circuitry are produced as a unit, which can be easily placed within a variety of bulkhead structures, and subsequently within a perforating gun.

A connector assembling structure is provided. The connector assembling structure includes a shell, a circuit board, a connector, a fixing member, and an elastic member. The circuit board is disposed on the shell. The connector is disposed on the circuit board. The fixing member is fixed on the shell. The elastic member is disposed on the fixing member. The circuit board includes a pillar. The fixing member includes a fixing member opening corresponding to the pillar. The pillar passes through the fixing member opening. The size of the fixing member opening is greater than the size of the pillar, such that the circuit board and the elastic member may move relative to the fixing member through the fixing member opening.

A pin has a compliant section at a first end and a welding section at a second end opposite the first end. The compliant section is electrically connected with a via of a printed circuit board. The welding section has a welded connection with a passive component.

The application discloses an electronic device including a motherboard and a housing structure. The motherboard has a first surface and a second surface. The housing structure includes a first casing, a first cushion, a second casing, and a second cushion. The first casing has at least one first fixing member. The first cushion covers the first surface, is accommodated in the first casing and has at least one first through hole. The second casing has at least one second fixing member. The second cushion covers the second surface, is accommodated in the second casing and has at least one second through hole. A peripheral edge of the first cushion is attached to a peripheral edge of the second cushion, and the first fixing member may be fixed to the second fixing member through the first through hole and the second through hole.

The invention relates to a module configured to reduce or eliminate NVH problems and electrical equipment provided with the module. Electrical equipment includes a housing; the housing includes a cover panel, a peripheral wall, and a chamber defined by the peripheral wall and the cover panel; a part of the cover panel is fastened to upper edges of the peripheral wall; and the electrical equipment further includes at least one support element which is installed inside the chamber at a distance from the peripheral wall, and is configured to support the cover panel.

A housing includes a case made of a resin material and having an open side, and a cover that covers the open side of the case. Screw holes that are open toward the cover are formed in a side wall of the case. Through holes are formed in the cover at positions facing the respective screw holes. The cover is fastened to the case by screwing cover bolts into the respective screw holes through the respective through holes. Insertion holes are formed to extend through the side wall in an assembly direction of the cover with respect to the case. The housing is attached to an attachment target made of a metal material, by screwing attachment bolts into respective attachment holes in the attachment target through the respective insertion holes. The attachment bolts are formed to press the cover against the side wall when inserted in the respective attachment holes.

A case is provided with a drainage channel that smoothly drains water while also being able to suppress the intrusion of water into a housing space. The case includes a first case body in which a channel extending from a region serving as the housing space is formed. The channel includes a first channel portion having one end side connected to a first outlet and another end side connected to a second outlet, and a second channel portion connects the first channel portion and the housing space. Out of the opening edges of the second channel portion that face the first channel portion, a second-side opening edge, which is the edge on the second outlet side of the first channel portion, is located nearer to the housing space than a first-side opening edge, which is the edge on the first outlet side of the first channel portion, is.

A control module for actuating at least one electrically operable actuator includes an actuator housing, a housing part, a casting space, a circuit carrier, and an electronic control circuit. The actuator housing accommodates the electrically operable actuator. The housing part is formed as one piece on the actuator housing. The casting space is formed on the housing part. The circuit carrier is introduced into the casting space. The electronic control circuit is arranged on the circuit carrier. The circuit carrier is surrounded with a casting mass in the casting space and embedded therein, and electrical connection elements of the circuit carrier are guided outwards out of the casting space.
