Abstract

An electric component assembly includes a housing with which an electric component is fitted together, and the electric component and the housing are fixed to one side of a base body. The electric component includes a connecting terminal configured to be press-fitted in a through-hole of the control board of the housing, and a direction in which the connecting terminal is inserted into the through-hole is same as a fitting direction relative to the housing. There are provided a rib protruding from one of the electric component and the housing, and a groove portion recessed from another one of the electric component and the housing and into which the rib is press-fitted. Movement of the electric component in a direction intersecting the fitting direction and rotation of the electric component around an axis parallel to the fitting direction are restrained by the rib press-fitted into the groove portion.

First claim

The invention claimed is:

1. An electric component assembly comprising:
an electric component; and
a housing with which the electric component is fitted together; the electric component and the housing being fixed to one side of a base body,
wherein the electric component includes a connecting terminal configured to be press-fitted in a through-hole of a circuit board installed in the housing, and a direction in which the connecting terminal is inserted into the through-hole is same as a fitting direction of the electric component relative to the housing,
wherein the electric component assembly includes a rib protruding from one of the electric component and the housing, and a groove portion recessed from another one of the electric component and the housing and into which the rib is press-fitted,
wherein movement of the electric component in a direction intersecting the fitting direction and rotation of the electric component around an axis parallel to the fitting direction are restrained by the rib press-fitted into the groove portion, and
wherein the rib is configured to provide an electric component bonding margin for bonding the electric component assembly to a front side of the base body using an adhesive when the rib is press-fitted into the groove portion.

2. The electric component assembly according to claim 1 , wherein the connecting terminal is a press-fit terminal.

3. The electric component assembly according to claim 1 , wherein the electric component is a coil assembly configured to drive a solenoid valve, and
wherein the coil assembly includes:
a bobbin;
a coil comprising a winding around the bobbin;
a yoke mounted on the bobbin; and
the connecting terminal electrically connected to the winding.

4. A brake fluid pressure control device for vehicles comprising the electric component assembly according to claim 3 , and configured to be connected between a master cylinder and a wheel brake and to control brake fluid pressure acting on the wheel brake,
wherein the solenoid valve is mounted on the base body, and the coil assembly is attached to the solenoid valve.

5. The electric component assembly according to claim 2 , wherein the electric component is a coil assembly configured to drive a solenoid valve, and
wherein the coil assembly includes:
a bobbin;
a coil comprising a winding around the bobbin;
a yoke mounted on the bobbin; and
the connecting terminal electrically connected to the winding.

6. A brake fluid pressure control device for vehicles comprising the electric component assembly according to claim 5 , and configured to be connected between a master cylinder and a wheel brake and to control brake fluid pressure acting on the wheel brake,
wherein the solenoid valve is mounted on the base body, and the coil assembly is attached to the solenoid valve.

7. The electric component assembly according to claim 1 , wherein said rib is a quadrangular prism-shaped rib.
