A connector device having a multiple of connector connection terminals of differing connector frontage forms is such that when there is a change in a disposition of a connector frontage, or when using a different connector connection terminal, there is a need to newly prepare a molding die for the whole device. Because of this, the invention includes a first step of fabricating an integrally molded article including a connector connection terminal, forming a connector housing by integrating a multiple of integrally molded articles fabricated in the first step, and forming a connector frontage corresponding to each integrally molded article.

Connector device manufacturing method

An external connection connector includes: an insulating resin molded body in which are formed integrally: a second flange portion that is fixed to a first axial end surface of a first bulging portion of a unit housing; an extended portion that extends from the second flange portion alongside an outer circumferential surface of the actuator housing toward the first axial end; a first flange portion that extends radially inward from a first axial end of the extended portion; and a connector portion that is formed on the first flange portion; and a plurality of electrical conductors that are insert-molded into the insulating resin molded body such that first ends thereof protrude inside the connector portion and second ends thereof protrude into a connection window that is formed on a second bulging portion of a heatsink, the electrical conductors being connected to control portion connecting terminals inside the connection window.

Automotive controlling apparatus

A commutator assembly for a motor has a recessed portion formed to each commutator segment so that coils, which are pressed and deformed by bending the hooks of commutator segments, can be accommodated in the recessed portion. With this arrangement, the commutator assembly can improve the reliability of electric connection of the hook of the commutator segments with a conductive wire.
