Unit integrated system and connector

Abstract

A connector having terminal groups (222) intended to carry a large current from a source of electrical power to an actuator for a hydraulic unit. The connector also has another terminal group (223) for a smaller current which is electrically connected to components of an electronic control unit (2) for hydraulic unit (1). Connector housing (221) is provided with base plate (221a) which carries terminal groups (222 and 223) and tubular housing body (221b) encloses both terminal groups (222 and 223). The terminals of both groups are joined at their outer ends to a harness-side connector (219) and at their inner ends the terminal group (222) is joined by wiring (224) to a motor (205) and the terminal group (223) is joined to a printed board (209). The board (209) along with a junction block (210) are housed within a pair of case elements (213a and 213b). There is also disclosed a unit integrated system wherein a hydraulic unit (1), having an upper surface (3a) defining an oil inlet, and an electronic control unit (2) for controlling the drive of the hydraulic unit (1) are integrated in juxtaposition to each other in such a manner that an upper surface (2a) of the electronic control unit is located at a position equal to or lower than the upper surface (3a) of the hydraulic unit (1), whereby an operating space (35) of a piping tool is insured above the electronic control unit (2).
