Control unit having press-fit structure
In a control unit including a press-fit terminal, a substrate includes: a connected portion into which the press-fit terminal is connected; and a guide member, which surrounds a periphery of the connected portion and extends from the substrate. The press-fit terminal includes: a connecting portion formed on a tip end side of the press-fit terminal; and an enlarged portion formed adjacent to the connecting portion. The guide member includes: an opening portion, which opens in a direction in which the press-fit terminal is positioned; a guide hole extending from the opening portion to the substrate; and a reduced-hole portion formed adjacent to the opening portion. The guide hole is configured such that, when the connecting portion of the press-fit terminal is connected to the connected portion of the substrate, the enlarged portion of the press-fit terminal closes the reduced-hole portion of the guide hole.
1. A control unit having a press-fit structure, comprising a connector assembly body and a substrate assembled to each other,
the connector assembly body including a press-fit terminal,
the substrate including:
a connected portion into which the press-fit terminal is connected; and
a guide member, which surrounds a periphery of the connected portion and extends from the substrate,
the press-fit terminal including:
a connecting portion formed on a tip end side of the press-fit terminal; and
an enlarged portion formed adjacent to the connecting portion,
the guide member including:
an opening portion, which opens in a direction in which the press-fit terminal is positioned;
a guide hole extending from the opening portion to the substrate; and
a reduced-hole portion formed adjacent to the opening portion,
the guide hole being configured such that, when the connecting portion of the press-fit terminal is connected to the connected portion of the substrate, the enlarged portion of the press-fit terminal closes the reduced-hole portion of the guide hole.
2. The control unit having a press-fit structure according to claim 1 ,
wherein the guide member includes a tapered surface which is formed inside the opening portion and has an inner dimension decreasing as separating away from the opening portion.
3. The control unit having a press-fit structure according to claim 1 , further comprising a base member configured to support the substrate at a position of being opposed to the guide member across the substrate,
wherein the base member includes a recessed portion configured to surround a periphery of the connected portion of the substrate.
4. The control unit having a press-fit structure according to claim 3 ,
wherein the guide member includes a tapered surface which is formed inside the opening portion and has an inner dimension decreasing as separating away from the opening portion.
