Patent number: 11569774Abstract: An actuator control device supplies electrical power to a plurality of actuators via a plurality of controller units consecutively disposed and connected in one direction. A power supply unit or an input/output and power supply unit is interposed between each arbitrary number of controller units from within the plurality of controller units. In a case that the power supply unit is interposed, the power supply unit supplies electrical power to the block connected on a downstream side in a connecting direction. In a case that the input/output and power supply unit is interposed, the input/output and power supply unit performs input and output of signals to and from an exterior and the block that is connected on the downstream side in the connecting direction, while also supplying electrical power to the block.Type: GrantFiled: May 12, 2022Date of Patent: January 31, 2023Assignee: SMC CORPORATIONInventors: Atsushi Fujiwara, Eiji Iijima

Patent number: 10063004Abstract: A controller assembly includes a plurality of controller units, and a heat dissipating unit interposed between the controller units. Male and female connectors are disposed in the controller units, and the connectors thereof are fitted to female and male connectors of the heat dissipating unit to thereby establish electrical contact therebetween. Upon driving electric actuators, heat generated in circuit boards of the controller units is dissipated to the exterior through a plurality of heat dissipating protrusions provided on the heat dissipating unit, so that heat generating sources of the circuit boards are cooled.Type: GrantFiled: February 7, 2017Date of Patent: August 28, 2018Assignee: SMC CORPORATIONInventors: Eiji Iijima, Atsushi Fujiwara, Takeshi Hirose
