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.

Electrical connection box

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.
