Patent number: 7993146Abstract: An electrical connector (a connector) includes a housing and a terminal disposed in the housing. The terminal includes a contact portion. When the connector is fitted to a mating connector in a fitting direction, the contact portion pushes a mating terminal of the mating connector in a pushing direction perpendicular to the fitting direction and deforms the mating terminal elastically in the pushing direction. The contact portion includes a guide portion and a sliding contact portion with a protruded band shape situated at a rear position in the fitting direction relative to the guide portion. The guide portion guides the mating terminal and the sliding contact portion slides against the mating terminal when the connector is fitted to the mating connector.Type: GrantFiled: November 24, 2009Date of Patent: August 9, 2011Assignee: Hirose Electric Co., Ltd.Inventor: Kazuya Midorikawa
