The triple sealing device for an electronics housing of smart instrumentation includes: an electronic board; a first housing which has the electronic board disposed therein and includes a first inlet port to allow a cable to pass therethrough; a second housing which is provided above the first inlet port of the first housing and coupled to the first housing, and includes a second inlet port to allow a cable to pass therethrough; an elastic block provided on an inner circumferential surface of the second inlet port; and a cable which is connected to the electronic board and extends outward after passing through the first inlet port and the second inlet port.

The disclosure relates to an electronic device including a housing filled to a fill level with a first matrix produced from a first potting compound, and a circuit board having a component arranged thereon and having a passageway that connects a component side arranged within the housing interior filled with the first matrix and a front face of the component arranged outside the housing interior filled with the first matrix, the passageway acts as capillaries for media whose viscosity is less than a limit and as barriers for media whose viscosity is greater than the limit, the component is arranged in a spatially bounded region adjoining the component side, a second matrix produced from a second potting compound having a viscosity exceeding the limit, which second matrix effects a terminal sealing of the connection formed by the passageway against the first potting compound used for producing the first matrix.

The present invention relates to an electrical device including a printed circuit board (PCB) accommodated in a case, and more particularly, to an air-pocket prevention PCB, an air-pocket prevention PCB module, an electrical device including the same, and a manufacturing method of an electrical device including the same with improved fluidity of a resin material so that air pockets that may occur when the case is filled with the resin material are easily discharged and the resin material may be evenly filled inside the case.

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 dishwasher includes a cabinet, a tub, a door, a control panel that is disposed in one side of the door and has an operation button, a printed circuit board that is disposed inside the control panel and detects an input for the operation button, a supporter that has a mounting space in which the printed circuit board is mounted and that is disposed inside the control panel, a waterproof film that is adhered to one side of the supporter facing the control panel and blocks water inflow into the printed circuit board disposed in the mounting space, and a coating layer filled with a waterproof material, in the mounting space of the supporter on which the printed circuit board is mounted.

A display device includes a housing including first and second edge areas; a panel assembly between a window and the housing; a first waterproof member corresponding to the first edge area; a second waterproof member corresponding to the second edge area and disconnected from the first waterproof member; and a first sealing member in contact with the first and second waterproof members, the panel assembly, the window and the housing. The panel assembly includes a plurality of members each protruded further than an end of the first waterproof member to respectively define first edges. Each first edge is in contact with the first sealing member, and protruded distances of the first edges from the end of the first waterproof member increase as a cross-sectional distance from the plurality of members to the window decreases to form a stepped shape of the panel assembly at the first edges.

A power module which inhibits disjoin between a sealing resin and an adhesive. The power module includes: an insulative substrate having a semiconductor element mounted on the top surface; a base plate joined to the rear surface of the insulative substrate; a case member with the base plate, that surrounds the insulative substrate, the case member having a bottom surface whose inner periphery portion side being in contact with a top surface of the base plate, the bottom surface being provided with an angled surface whose distance to the top surface of the base plate increases toward an outer periphery side of the base plate; an adhesive member filled between the base plate and the angled surface to adhere the base plate and the case member; and a filling member filled in a region bounded by the base plate and the case member.

A sensor is provided with a cylindrical-shaped housing which has an opening formed at one end, an electronic component which is housed in the housing, a cylindrical-shaped clamp of which one end is inserted into the housing from the opening, and a sealing resin which seals the gap between the inner wall of the housing and the outer wall of the clamp. On the outer wall, the clamp has a rib which rises towards the inner wall of the housing. The rib includes an apex and a sloped surface which extends from the apex towards another end of the clamp and which intersects the outer wall of the clamp. The sealing resin, which exudes from between the inner wall of the housing and the apex and which is positioned on the sloped surface, has a recess resulting from surface tension.

An explosion proof electronics enclosure (200), is provided having a first compartment (206) and a second compartment (207) defined by a body (205). A septum (208) is between the first compartment (206) and the second compartment (207). A first aperture (209) in the septum (208) connects the first compartment (206) and the second compartment (207). A cavity (225) communicates with the first aperture (209), wherein the cavity (225) comprises an undercut taper (226). A potting (230) in the cavity (225) conforms to the cavity (225) shape, and forms a substantially explosion-proof interface between the first compartment (206) and the second compartment (207).

A control arrangement and a control module for a milking position for milking a dairy animal includes a casing forming an inner space enclosing a printed circuit board incorporating a control system for controlling and supervising at least some functions of the milking position. A communication area is provided on a front side of the printed circuit board and communicates with the control system. The casing includes an inner front plate. The front side of the printed circuit board is attached to a rear side of the inner front plate by a transparent adhering substance so that a part of the printed circuit board projects from the rear side of the inner front plate. The inner front plate permits access to the communication area. The part of the printed circuit board is embedded in a block of plastic material.
