Abstract

A first electronic control unit (10) provided with a printed circuit board (13) and a second electronic control unit (E) having pressure sensors (30) mounted therein can be assembled with each other. Intermediate connectors (40) are mounted in the first electronic control unit (10), and terminal fittings (42) are accommodated therein. Each terminal fitting (42) is provided with a board-side connecting portion (53) to be soldered to the printed circuit board (13) and a resilient contact piece (51) to be resiliently brought into contact with a terminal portion (32) of the pressure sensor (30).

Claims

1. A construction for electrically connecting a circuit board in a first unit box and an electrical part in a second unit box as the first and second unit boxes are assembled, the electrical part having at least one terminal fitting, the first unit box having an intermediate connector with at least one terminal fitting having a first portion inseparably connectable with the circuit board and the terminal fitting further having a second portion separably connectable with the terminal of the electrical part so that the second unit box and the terminal fitting thereof can be detached from the first unit box and the terminal fitting thereof, wherein the intermediate connector is mounted in the first unit box via a displacement take-up means for resilient displacement relative to the first unit box in a direction intersecting with an assembling direction of the two unit boxes.

2. The construction of claim 1, wherein:

the intermediate connector is mounted with the terminal fitting inserted through a mounting portion in a unit main body of the first unit box, and

the displacement take-up means includes at least one resilient piece on one of the intermediate connector and the unit main body and being resiliently deformable in the direction intersecting with the assembling direction, and a receiving portion on the other of the intermediate connector and the unit main body for receiving the resilient piece.

3. The construction of claim 2, wherein the intermediate connector includes at least one holding portion engageable with the mounting portion as the intermediate connector is turned along a circumferential direction after being inserted into the mounting portion, and the resilient piece extends substantially along the circumferential direction of the intermediate connector and is engageable with a side of the mounting portion substantially opposite from the side where the holding portion is to be engaged with the mounting portion.

4. The construction of claim 2, wherein the resilient piece extends substantially along the assembling direction of the two unit boxes and includes a resiliently deformable arm and a lock engageable with a side of the mounting portion substantially opposite from the side where the intermediate connector is to be mounted.

5. The construction of claim 4, wherein at least one of the lock and the mounting portion has a guiding surface for guiding the arm to undergo a resilient deformation as the intermediate connector is mounted along the assembling direction of the two unit boxes.

6. A brake oil pressure control unit comprising the construction for connecting a circuit board and an electrical part of claim 1.
