Abstract: An electrical connection box is provided in which a printed circuit board provided with a lateral connection-type connector is housed in a case, and a cover is attached to the case, and this electrical connection box has a novel structure in which a reduction in size and manufacturing cost can be achieved while still reliably protecting the connector. A surface mount-type connector is provided on a printed circuit board as the lateral connection-type connector, and the case and the cover are provided with incorrect-connection-prevention projection portions that, in the case where the cover is brought close to the case upside down relative to the proper orientation, prevent incorrect attachment of the cover by abutting against each other before the cover abuts against the connector.

Abstract: A case includes a case body and a cover member. The case body includes a bottom wall portion having a surface area which allows selective accommodation of a first substrate and a second substrate and an outer peripheral portion. The outer peripheral portion includes a front wall portion (a reference wall portion), a pair of left and right wall portions which come into abutment with lateral sides of the first and second substrates, and ribs (first restraint portions) configured to restrain the first substrate in cooperation with the front wall portion at a position where a reference side of the first substrate comes into abutment with the front wall portion. The case body includes a diaphragm (a second restraint portion) configured to restrain the second substrate in cooperation with the front wall portion at a position where a reference side of the second substrate comes into abutment with the front wall portion.

Abstract: Some embodiments protect aluminum electrolytic capacitors without increasing the thickness or height dimension of a unit case of an onboard electronic control unit, which is provided with the unit case and a circuit board on which the aluminum electrolytic capacitors are mounted. The circuit board includes a first surface and a second surface, and the unit case houses the circuit board. The unit case includes a first main wall facing the first surface, a second main wall facing the second surface, and perimeter walls. The capacitors are mounted on the second surface so as to extend along a specific periphery of the circuit board and be mutually connected in parallel. The unit case has a height dimension capable of housing the aluminum electrolytic capacitors without the aluminum electrolytic capacitors contacting the inside surface of the second main wall.

Abstract: An assemble structure includes: a connection device including a support element on one side of an attachment surface, a first connector on the attachment surface, and a key groove on a support surface of the support element; and the electric device including a casing to be attached to the attachment surface, a second connector on one surface of the casing electrically coupled with the first connector, and a key protruding from the one side of the casing. The electric device is rotatable via a hinge provided by the support element and the casing when one side of the casing faces a support surface of the support element. The key groove on the support surface corresponds to the key on the one side of the casing.

Abstract: A vehicle-mounted unit (2) has two brackets (21) and (22) with bolt through-holes (23). The vehicle-mounted unit (2) is installed on an interior of a vehicle body by inserting stud bolts (3) into the bolt through-holes (23) and screwing hexagonal nuts (4) onto the stud bolts (3). Each of the brackets (21) and (22) has a slide passage (25) that extends from an outer periphery of the bracket to the bolt through-hole (23) to laterally guide the stud bolt (3). Each slide passage (25) is formed so that the vehicle-mounted unit (2) can detachably slide on each stud bolt (3) in a direction perpendicular to an axis of the bolt (3).
