Abstract: A connector connecting structure can block liquid leakage outside a liquid-filled case and reduce the size of the device including a number of elements and a liquid sealed case and the number of electrical connection points. A connector connecting structure is provided with a connector AT connector (first connector) fixed to an AT case, an ECU connector (second connector) connected to the AT connector (first connector), a first sealing member sealing a space between the AT case (liquid sealed case) and the AT connector (first connector), and a second sealing member sealing a space between an ECU side housing (second housing) and a male-type terminal (second terminal).

Abstract: Provided is a connection structure and a device composite capable of suppressing terminal wrench while suppressing increase in size and assembly cost. The connector connection structure 1 includes an AT connector (first connector), and an ECU connector (second connector), the ECU side housing (second housing) is provided with a protrusion extending in a connector connection direction, that is, the direction of the terminal connection of a female type terminal (first terminal) and a male type terminal (second terminal), entering the AT side housing (first housing) prior to terminal connection, the AT side housing (first housing) is provided with a guide recess for guiding the terminal connection by entering of the protrusion.

Abstract: A vehicle control device (100) includes: a housing (200) made of metal; a substrate (400) housed in the housing (200) and having a mounting surface (401) that faces an inner surface (201) of the housing (200); and an electronic component (501) mounted on the mounting surface (401). An adhesive (601) is disposed between the electronic component (501) and the inner surface (201) of the housing (200). The electronic component (501) has a contact portion (532) that contacts the heat radiation material (601) and a non-contact portion (531) that does not contact the heat radiation material (601). The contact portion (532) and the non-contact portion (531) are portions of the electronic component (501) on the side facing the inner surface (201) of the housing (200).
