A case structure includes: a case having an opening at one end side; a cover configured to close the opening; and a pressing and holding portion configured to press and hold a board against the case when the cover applies a force to the board in a state where the board is accommodated in the case and the cover is closed.

A vehicle lighting control circuit box is provided, including a case member, a circuit unit, at least one cover member and a positioning assembly. The case member is a metal member and extends along a longitudinal direction, the case member defines a receiving space, and two ends of the case member on the longitudinal direction respectively have an opening communicating with the receiving space. The circuit unit is received in the receiving space. Each of the at least one cover member covers one of the two openings. The positioning assembly is disposed on the case member to position the circuit unit within the receiving space to make the circuit unit contact with the case member.

An electronic device includes a board having a mounting surface for an electronic component, a case having an opening for insertion of the board into the case and configured to house the board inserted through the opening, and a cover fixed to the case so as to close the opening. The board also has at least one deformable device formed on an end side of the board and configured to be elastically deformable in a direction orthogonal to the mounting surface. The deformable device comes into contact with the case or the cover in a state of being elastically deformed to hold the board in a fixed state in a storage space formed through fixation of the cover to the case when the board is housed in the storage space.

A printed board joining method according to an embodiment includes preparing a printed board having, on an upper surface, a plurality of connection land portions provided along a side end, preparing a printed board having, on a lower surface, a plurality of connection land portions along a side end, and joining the printed board and the printed board together with a conductive joining material such that the upper surface is opposed to the lower surface and the plurality of connection land portions are electrically connected to the corresponding connection land portions. One or more cutout portions are provided between the plurality of connection land portions and/or between the plurality of connection land portions.

A control module with manual switches for controlling the ON/OFF status, brightness, and flashing pattern of a high-power variable current electrical device. The control module is intended for use with the interlocking modular frames of U.S. patent application Ser. No. 15949518, but may be used with other switch panels as well. The control module also includes at least one radio transceiver configured to receive communications from a smartphone application for controlling a high-power variable current electrical device attached to the control module. In some embodiments, the smartphone application may provide more control options than are provided by the manual switches on the front of the control module.

The invention relates to a housing for an electrical device, in particular an electrical machine. The housing encloses a cavity. The housing has a housing cup and a housing part. The housing part, which is formed, for example, by a closing element, in particular a housing cover, is designed to be connected to the housing cup, in particular separably or inseparably, or to close the housing cup. According to the invention, the housing cup, in particular a housing wall of the housing cup, has an opening. The housing cup is made of metal, in particular steel or aluminum, at least in the region of a housing cup edge extending peripherally around the opening. The housing part is preferably made of plastic. The housing preferably has an adapter, which is in particular tubular, for connecting the housing cup to the housing part. The adapter is injection-molded or fused onto a longitudinal section of the housing cup edge. The adapter has, at an end opposite the housing cup, an adapter edge, which surrounds an adapter opening, is in particular in the form of a flange and is designed to be adhesively bonded or welded, in particular tightly, to the housing part.

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 housing for accommodating a single or multi-part printed circuit board includes an opening in a first housing side for inserting the printed circuit board, at least one guide rail having a groove for receiving the printed circuit board and being situated on at least one first housing side wall of a group of housing side walls running perpendicularly to the first housing side. The guide rail is configured to receive a peg disposed on one of the printed circuit board parts. The guide rail runs from the first housing side towards a second housing side opposite the first housing side, so that the end of the guide rail near the first housing side is further away than the other end of the guide rail from the housing side wall which is oriented perpendicularly to the first housing side wall and is closest to the guide rail.

A substrate case can be used in common with different types of substrates, and thus reduces production costs. A substrate case is tubular and has a bottom that includes an open portion into which a first substrate and a second substrate that has a different size can be selectively inserted. Guide portions are configured to guide movement of the first substrate and the second substrate in an insertion direction when the first substrate and the second substrate are selectively inserted through the open portion. A first restricting portion is configured to restrict movement of the first substrate when the first substrate has been guided by the guide portion and inserted to a regular position; and a second restricting portion that is configured to restrict movement of the second substrate when the second substrate has been guided by the guide portion and inserted to the regular position.
