Patent number: 10505290Abstract: A wire connection portion of a terminal has a first part and a second part. The first part has two first sidewall portions and a first coupling portion coupling them. The first sidewall portions are located apart from each other in a lateral direction. The second part has two second sidewall portions and a second coupling portion coupling them. The second sidewall portions are located apart from each other and outside the first sidewall portions, respectively, in the lateral direction. The first coupling portion is located apart from the second coupling portion in an up-down direction. The first sidewall portions are provided with contact portions, respectively, to be brought into contact with an electrical wire. When the electrical wire is connected to the terminal, the contact portions sandwich the electrical wire in the lateral direction. The contact portions may be rounded to press on sides of a bare wire placed in the device.Type: GrantFiled: December 20, 2018Date of Patent: December 10, 2019Assignee: Japan Aviation Electronics Industry, LimitedInventors: Masakazu Kuroiwa, Hiroaki Obikane

Patent number: 10411405Abstract: A connector comprising a housing and a lever. The connector is mateable with and removable from a mating connector along a first direction by operation of the lever. The housing has an inner portion, an outer portion, at least one coupling portion, a pivot, a first portion and a second portion. The housing has a lever accommodating portion between the outer portion and the inner portion in a second direction perpendicular to the first direction. The lever accommodating portion partially accommodates the lever. The pivot is positioned inside the lever accommodating portion. The pivot supports the lever so that the lever is rotatable. The at least one coupling portion has a bridge portion which is elastically deformable. The bridge portion is sandwiched between the first portion and the second portion in a plane perpendicular to the second direction.Type: GrantFiled: April 10, 2018Date of Patent: September 10, 2019Assignee: Japan Aviation Electronics Industry, LimitedInventors: Yusuke Obata, Masakazu Kuroiwa

Patent number: 10403998Abstract: A female terminal comprises a main body, a main spring portion and an auxiliary spring portion. The main body forms a receiving portion. The receiving portion opens forward in a front-rear direction. The main spring portion has a first spring piece, a second spring piece and a contact portion. The contact portion is held between the first spring piece and the second spring piece in the front-rear direction. The auxiliary spring portion has a first support portion, a second support portion and a resilient supporting portion. The first support portion supports the first spring piece when a male terminal and the female terminal are connected with each other. The second support portion supports the second spring piece when the male terminal and the female terminal are connected with each other. The contact portion is positioned between the first support portion and the second support portion in the front-rear direction.Type: GrantFiled: July 18, 2018Date of Patent: September 3, 2019Assignee: JAPAN AVIATION ELECTRONICS INDUSTRY, LIMITEDInventors: Toshikazu Hayashi, Masakazu Kuroiwa

Patent number: 10270195Abstract: A connector is provided with a female contact and a housing. A protection portion of the female contact has a guide portion intersecting with a front-rear direction to guide a male contact to a receiving portion. An insertion opening of the housing is located forward of a contact accommodation portion in the front-rear direction. The insertion opening opens in a predetermined direction perpendicular to the front-rear direction and thereby communicates with an aperture portion. When a front of the connector is viewed along the front-rear direction, the guide portion is visible through the insertion opening at least in part.Type: GrantFiled: July 9, 2018Date of Patent: April 23, 2019Assignee: JAPAN AVIATION ELECTRONICS INDUSTRY, LIMITEDInventors: Toshikazu Hayashi, Masakazu Kuroiwa
