Unit integrated system and connector

A unit integrated system comprising:

• an electronic control unit having a relay and a control circuit, and
• a hydraulic unit having a solenoid, said electronic control unit and said hydraulic unit being integrated together,
• said relay, said control circuit, and said solenoid being electrically connected to each other,
• said relay being located adjacent a first major surface of said hydraulic unit,
• said control circuit being located adjacent a second major surface of said hydraulic unit.

A unit integrated system comprising:

• an electronic control unit and a hydraulic unit integrated together,
• said electronic control unit including first and second divided case elements formed into an integral configuration, and a plurality of screws for fixing said first and second divided case elements in joined relation,
• said first divided case element including a plurality of fixing members projecting toward said second divided case element from a surface of said first divided case element opposed to said second divided case element when said first divided case element is integrated with said second divided case element,
• said second divided case element including a plurality of screw support members projecting outwardly from an outer surface thereof in corresponding relation to said fixing members,
• said screw support members having screw support holes receiving said screws, respectively,
• said fixing members including female threaded portions in threaded engagement with the screws inserted into the screw support holes, with said first and second divided case elements joined together.

A unit integrated system comprising:

• an electronic control unit having a fail-safe relay including a make relay, and a control circuit;
• a hydraulic unit integrated with said electronic control unit and having a solenoid operated by a control output from said control circuit;
• a battery;
• a connector for connecting said fail-safe relay and said control circuit to said solenoid and said battery;
• alarm means for signalling the unconnectedness of said connector;
• and
• conduction means provided in a current conduction path extending from said battery to said alarm means for rendering said current conduction path conductive when said connector is not connected,
• said fail-safe relay including a relay coil having a first end connected to said battery and a second end connected to said control circuit.
