Patent number: 11545795Abstract: A connector includes: a cylindrical terminal to be electrically connected with a cylindrical counterpart terminal; an internal terminal located in the cylindrical terminal; and a housing holding the cylindrical terminal. The cylindrical terminal has a contact portion configured by bending a plate-shaped conductor into a cylindrical shape to contact one edge portion of the conductor with the other edge portion of the conductor. The one edge portion has a recessed shape at its circumferential end portion by reducing its thickness outwardly in a radial direction of the cylindrical terminal to configure one reduced thickness portion. The other edge portion has a recessed shape at its circumferential end portion by reducing its thickness inwardly in the radial direction to configure the other reduced thickness portion. The contact portion is configured by overlapping the one reduced thickness portion and the other reduced thickness portion.Type: GrantFiled: May 25, 2021Date of Patent: January 3, 2023Assignees: YAZAKI CORPORATION, TAKASAKI MFG. CO., LTD.Inventors: Toshiro Maejima, Kouichirou Matsushita, Takuya Otake, Fujio Usui

Patent number: 11495925Abstract: A connector includes: a cylindrical terminal; an internal terminal; and a housing. The cylindrical terminal has an engagement portion of its one edge portion and its opposite other edge portion. The one edge portion has a first reduced thickness portion at its circumferential end portion. The first reduced thickness portion has a first protrusion protruding inwardly in a radial direction and extending in an axial direction. The other edge portion has a second reduced thickness portion. The second reduced thickness portion has a second protrusion protruding outwardly in the radial direction and extending in the axial direction. The engagement portion is configured by overlapping the first reduced thickness portion and the second reduced thickness portion and further by locating the first protrusion and the second protrusion to face each other in the circumferential direction to allow an engagement between them in the circumferential direction.Type: GrantFiled: May 25, 2021Date of Patent: November 8, 2022Assignee: YAZAKI CORPORATIONInventors: Toshiro Maejima, Kouichirou Matsushita, Takuya Otake
