Publication number: 20240039201Abstract: A connector comprises a contact pin, a housing into which the contact pin is inserted, and a retainer. The contact pin includes a contact point portion formed on an end thereof and defining an opening adapted to receive a mating contact, and an engagement portion. The engagement portion is defined at least partially through the contact point portion, and includes a continuous opening formed partially through a side wall of the contact point portion in a height direction and partially through a top wall or a bottom wall of the contact point portion in a width direction. The retainer is insertable into the housing in a direction intersecting the direction of insertion of the contact pin. The retainer is adapted to be inserted into the housing and engage with the engagement portion of the contact pin to secure the contact pin within the housing.Type: ApplicationFiled: July 27, 2023Publication date: February 1, 2024Applicant: Tyco Electronics Japan G.K.Inventors: Tsugumi Matsumoto, Tetsuro Akiguchi, Yuki Tsutsui, Seiji Shishikura, Yusuke Mito

Publication number: 20220376432Abstract: The sealing element of the waterproof connector has a shape in which a family seal portion that waterproofs the peripheries of electric wires which are sandwiched between an inner housing and an outer housing 40, and which are not illustrated, and a seal ring portion that performs waterproofing between the seal ring portion and a mating housing are integrated. The standing board portions of the inner housing penetrate the long openings of the sealing element, and the portion to be caught of the outer housing is caught by catch protrusion portions that are formed in upper portions of the standing board portions and each have a hook shape, whereby the inner housing and the outer housing are assembled in a state in which the family seal portion of the sealing element is sandwiched between the inner housing and the outer housing. The mating housing comes into contact with the third waterproof portion of the sealing element, which acts as the seal ring portion.Type: ApplicationFiled: May 19, 2022Publication date: November 24, 2022Applicant: Tyco Electronics Japan G.K.Inventor: Tetsuro Akiguchi

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: 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
