Therefore, the flexibility at the tip end portion (electrical component side connecting portion 32) of the electric component side connection terminal 30 can be secured, and the position tolerance generated when the electric component assembly 20 is electrically connected to the housing 10 is absorbed. Can do.
Further, when vibration is applied to the electrical component assembly 20 after assembly, it is preferable that the entire electrical component side connection terminal 30 bends and stress is concentrated on a part of the electrical component side connection terminal 30. Can be prevented. Thereby, durability can be improved.

  In addition, other components (such as an electrical component (not shown) or a component mounted on the base 1 side) are provided in an empty space formed by increasing the length from the electrical component assembly 20 to the electrical component side connection portion 32. Can be arranged. Thus, without enlarging the housing 10 in the direction perpendicular to the direction along the front surface 13a of the intermediate wall portion 13 of the electrical component assembly 20 (the front-rear direction of the brake control device U that is the axial direction of the electrical component assembly 20). A brake control device U that can efficiently accommodate the electrical component assembly 20 and other components in the housing 10 is obtained (while reducing the size of the housing 10 in the front-rear direction of the brake control device U).

  Further, two electrical component assemblies 20 are accommodated next to each other in the housing 10, and the bent portions 33 of the electrical component assemblies 20 are respectively connected to the electrical component assemblies 20 disposed adjacent to each other. Since the electric component side connection portion 32 is bent so as to extend toward the electric component side, each electric component side connection terminal 30 and the electric component assembly 20 can be arranged close to each other, and electric connection work can be performed efficiently. It can be carried out.

  Moreover, since the bending part 33 is formed wider than the base end part 31, the rigidity of the bent part of the electrical component side connection terminal 30 can be increased. As a result, when an external force acts on the electrical component assembly 20 and vibrations occur after assembly, stress can be suitably prevented from concentrating on this portion.

  Moreover, since the electrical component assembly 20 has the terminal support part 26 (resin part) by which the electrical component side connection terminal 30 was integrally shape | molded, the electrical component side connection terminal 30 was connected by the connection part 31a. Since it can be configured as a hoop terminal and the electric component side connection terminal 30 and the terminal support portion 26 can be hoop-molded, the molding efficiency is improved.

  Moreover, since the electrical component side connection terminal 30 of the electrical component assembly 20 has the wire connection part 36 and the binding part 34 which electrically connect a wire, the electrical connection part for electrically connecting or connecting a wire It is no longer necessary to provide a separate or binding portion, and the entire electrical component assembly 20 can be reduced in size. As a result, the housing 10 that houses the electrical component assembly 20 can be downsized.

  In addition, the electrical component side connection terminal 30 is formed so that the distal end side portion of the base end portion 31 adjacent to the binding portion 34 is wider than the binding portion 34. The electrical component side connection terminal 30 is provided with a guide function when the wire is connected, so that the wire binding position can be optimized.

These may be extended (projected) inward to be electrically connected in the first storage chamber 11A. In this case, the electrical connection jig 50 (electrode) may be moved from the first storage chamber 11A side into the first storage chamber 11A. Can be obtained.

  Moreover, in the said embodiment, the base end part 31 of the electrical component side connection terminal 30 is extended in the left-right direction in parallel with the back surface (surface by which the electrical component side connection terminal 30 is provided) of the electrical component assembly 20. FIG. However, the present invention is not limited to this, and the electrical component side connection terminal 30 up to the housing side connection terminal 16 is extended so as to have an angle on the side away from the back surface of the electrical component assembly 20.
