Patent number: 11545419Abstract: A semiconductor device includes a first switching element; a second switching element; a first metal member; a second metal member; a first terminal that has a potential on a high potential side; a second terminal that has a potential on a low potential side; a third terminal that has a midpoint potential; and a resin part. A first potential part has potential equal to potential of the first terminal. A second potential part has potential equal to potential of the second terminal. A third potential part has potential equal to potential of the third terminal. A first creepage distance between the first potential part and the second potential part is longer than a minimum value of a second creepage distance between the first potential part and the third potential part and a third creepage distance between the second potential part and the third potential part.Type: GrantFiled: January 4, 2019Date of Patent: January 3, 2023Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, DENSO CORPORATIONInventors: Takuya Kadoguchi, Takahiro Hirano, Arata Harada, Tomomi Okumura, Keita Fukutani, Masayoshi Nishihata

Patent number: 9912089Abstract: An electrical connector is disclosed having a terminal housing, a female terminal, and a holding protrusion. The female terminal is positioned in the terminal housing and has a terminal body into which a complementary male terminal may be inserted and extracted. The holding protrusion projects from the terminal body in a direction orthogonal to inserting and extracting directions, and is press-fitted in the terminal receiving terminal housing.Type: GrantFiled: February 4, 2015Date of Patent: March 6, 2018Assignees: Tyco Electronics Japan G.K., Toyota Jidosha Kabushiki KaishaInventors: Tetsuro Akiguchi, Kazuhiko Ueda, Natsuki Nozawa, Hitoshi Ozaki, Masao Noguchi, Arata Harada

Patent number: 9521758Abstract: A semiconductor device includes a semiconductor module that has an electrode terminal projecting externally; a substrate that has a through hole or a cut-out for inserting the electrode terminal; and a guide member that is provided between the semiconductor module and the substrate and guides the electrode terminal in such a manner that the electrode terminal is inserted into the through hole or the cut-out. The guide member becomes out of contact with the electrode terminal after the electrode terminal is inserted into the through hole or the cut-out.Type: GrantFiled: May 19, 2014Date of Patent: December 13, 2016Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, DENSO CORPORATIONInventors: Keita Hatasa, Arata Harada, Daisuke Harada

Patent number: 9509069Abstract: An electrical connector is disclosed having a housing and a female terminal. The housing has an assembly receiving space. The female terminal is positioned in the assembly receiving space and has a first female terminal, a second female terminal, and an elastic connecting spring. The first female terminal has a first contact receiving space. The second female terminal has a second contact receiving space and is independently displaceable relative to the first female terminal along a longitudinal axis. The elastic connecting spring connects the first female terminal to the second female terminal.Type: GrantFiled: December 22, 2014Date of Patent: November 29, 2016Assignees: Tyco Electronics Japan G.K., Toyota Jidosha Kabushiki KaishaInventors: Ryuichi Komiyama, Tetsuro Akiguchi, Yoshifumi Suemitsu, Kazuhiko Ueda, Natsuki Nozawa, Hitoshi Ozaki, Masao Noguchi, Arata Harada

Patent number: 9502815Abstract: An electrical connector is disclosed having a terminal housing and a female type terminal positioned in the terminal housing. The terminal housing has a first terminal housing, and a second terminal housing positioned independent from the first terminal housing. The female type terminal has a first female terminal, second female terminal, and a coupling member. The first female terminal is positioned in the first terminal housing and is electrically connected to a first male terminal. The second female terminal is positioned in the second terminal housing and is electrically connected to a second male terminal. The coupling member connects the first female terminal to the second female terminal.Type: GrantFiled: February 4, 2015Date of Patent: November 22, 2016Assignees: Tyco Electronics Japan G.K., Toyota Jidosha Kabushiki KaishaInventors: Tetsuro Akiguchi, Kazuhiko Ueda, Natsuki Nozawa, Hitoshi Ozaki, Masao Noguchi, Arata Harada

Publication number: 20160322726Abstract: A terminal connecting structure includes: a male terminal; and a female terminal to which the male terminal is fitted. The male terminal includes a first metal material and a first metal film that is formed on an outermost surface of the male terminal to coat the first metal material directly or indirectly. The female terminal includes a second metal material and a second metal film that is formed on an outermost surface of the female terminal to coat the second metal material directly or indirectly. A hardness of the first metal material is different from a hardness of the second metal material.Type: ApplicationFiled: December 30, 2014Publication date: November 3, 2016Applicants: TOYOTA JIDOSHA KABUSHIKI KAISHA, DENSO CORPORATIONInventors: Takuya KADOGUCHI, Takahiro HIRANO, Arata HARADA, Tomomi OKUMURA, Keita FUKUTANI, Masayoshi NISHIHATA
