Patent number: 9504178Abstract: A draining member protrudes from both openings of a through-hole in a vehicle control device. It has a pair of spaced elastic members extending from a connection. The connection has a width smaller than a width of the through-hole. The width between the elastic members varies from the connection toward their ends, reaching a narrow portion smaller than the width of the through-hole via an increased width portion greater than the width of the through-hole. A leg portion beyond the narrow portion has a width greater than the width of the through-hole. A minimum distance between a location where the width between the increased width portion and the narrow portion matches the width of the through-hole, and another location where the width of the leg portion is equal to or greater than the width of the through-hole, is equal to or greater than a thickness of the housing.Type: GrantFiled: April 18, 2013Date of Patent: November 22, 2016Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Yasuaki Mamoto, Yoshiji Arai

Patent number: 9270199Abstract: A filter capacitor accumulating direct-current power and a semiconductor device module performing a switching operation that converts the direct-current power accumulated in the filter capacitor to alternating-current power are electrically connected with each other through a laminated bus bar. The laminated bus bar has a first bus bar and a second bus bar in which a plurality of connection conductors are laminated through an insulator. The second bus bar is provided with heat radiating portions that are formed by exposing a part of the conductor in each flat plate surface.Type: GrantFiled: February 10, 2011Date of Patent: February 23, 2016Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Tomohiro Kobayashi, Kohei Sakamoto, Takeshi Yamamoto, Yasuaki Mamoto, Yukio Nakashima

Patent number: 8701809Abstract: A vehicle control device includes plural functional modules each of which is a minimum part unit that contributes to change in input/output potentials, and has an input and an output of one power line or one set of power lines, except for power lines having a same potential as that on an overhead wire side or that on a ground side. The functional module has an interface surface on one side surface, to which both of a signal line and the power line are connected. Each interface surface is divided into a first interface area in which a signal line terminal connected to the signal line is placed, and a second interface area in which a power line terminal connected to the power line is placed. The plural functional modules are adjacently arranged such that the interface surfaces face in a same direction, the first interface areas are located on one end side in common, and the second interface areas are located on the other end side in common.Type: GrantFiled: October 10, 2008Date of Patent: April 22, 2014Assignee: Mitsubishi Electric CorporationInventors: Minoru Ikemoto, Hideo Okayama, Yasuaki Mamoto, Yoshio Nagatsuka, Tetsuya Takahashi, Hidetoshi Sumita

Publication number: 20120306219Abstract: A cover locking mechanism is provided to a cover hinged to an opening portion of a casing to be openable/closable and has a latch formed hookable on to a circumference of the opening portion of the casing. It includes a plate spring, one end of which (one end of the plate spring) is attached to the cover, and which provides a biasing force in a direction from an inner side of the cover toward the circumference to the latch thereby to bias the latch attached to the other end (other end of the spring) toward the circumference and to bring the latch into contact with the circumference. The latch has a configuration (first notch) for holding the cover at a first angle and a configuration (second notch) for preventing the cover from being opened beyond a second angle greater than the first angle, during cover opening operation.Type: ApplicationFiled: February 16, 2010Publication date: December 6, 2012Applicant: MITSUBISHI ELECTRIC CORPORATIONInventors: Akiyo Takada, Yasuaki Mamoto

Publication number: 20080125926Abstract: A plurality of electric devices constituting an electric vehicle control device (6) are arranged as a unitary block of a frame and a case. A fixed unit (6a) is arranged at several positions on a horizontal plane between the upper end and the lower end of the electric control device mounted on an electric vehicle (1). The electric devices are arranged so that the center of gravity of the electric vehicle control device (6) is substantially on the horizontal plane of the fixed unit (6a). Since it is possible to suppress vibration during travel of the electric vehicle, it is possible to reduce the strength of the electric vehicle and reduce its weight.Type: ApplicationFiled: October 27, 2005Publication date: May 29, 2008Applicant: Mitsubishi Electric CorporationInventors: Yasuaki Mamoto, Hidetoshi Sumita
