Abstract
A terminal connector in an electric motor permits easy and smooth connection between a brush terminal and a power terminal by installing a case cover to a case frame. A support plate fixed to the case cover is divided into a terminal portion provided with a power terminal and an output shaft portion disposed on the output shaft side. The terminal portion is supported so that it is movable with respect to the output shaft portion. During assembly the terminal portion is movable to assure connection between the brush terminal and the power terminal.
Claims19
A terminal connector for an electric motor with a speed reducer having an output shaft, the terminal connector comprising a support plate having at least one power terminal for electrical connection with at least one brush terminal of said motor, said support plate including a first portion and a second portion, said first portion being provided with said at least one power terminal and said second portion being located adjacent said output shaft, said first portion being movable with respect to said second portion to facilitate alignment and connection of said at least one power terminal with said at least one brush terminal.
A terminal connection for an electric motor with a speed reducer and an output shaft, comprising:
- a case frame;
- a case cover for attachment to the case frame;
- a brush holder fixed to said case frame and including a brush terminal;
- and
- a support plate fixed to said case cover
- wherein
- said support plate comprises a terminal portion provided with a power terminal and an output shaft portion;
- and
- said terminal portion being movable with respect to said output shaft portion so that, when said case cover is installed from an axial direction of the output shaft with respect to said case frame, said power terminal and said brush terminal are aligned for electrical connection to each other.
A method of electrically connecting a power terminal mounted on a support plate with a brush terminal of an electric motor having a speed reducer and an output shaft, the method comprising:
- supporting the output shaft and a brush holder of the motor on a case frame, the brush holder including the brush terminal,
- dividing the support plate into two sections, a terminal section having the power terminal mounted thereon and an output shaft section,
- attaching the support plate to a case cover such that the terminal section of the support plate is movable in relation to the output shaft section,
- installing the case cover over the case frame in an axial direction of the output shaft;
- and
- moving the terminal section relative to the output shaft section to electrically connect the power terminal with the brush terminal while accommodating any dimensional misalignments between the case cover and case frame.
A method of electrically connecting a power terminal mounted on a support plate with a brush terminal of an electric motor having a a case cover, the method comprising:
- dividing the support plate into two sections, a terminal section having the power terminal mounted thereon and an output shaft section,
- attaching the support plate to the case cover, and
- moving the terminal section relative to the output shaft section to electrically connect the power terminal to the brush terminal.
