  • Patent number: 11848527
    Abstract: A terminal includes a terminal body and a slider. The terminal body is formed by processing a metal sheet. The terminal body is coupled to a front end of an electric wire with respect to an extending direction in which the electric wire extends. The terminal body holds the electric wire. The slider is slidable in the extending direction relative to the terminal body. The terminal body includes connecting tabs that includes contact surfaces contactable with the electric wire. Each of the connecting tabs has a cantilever shape. The slider includes pressing portions that press the connecting tabs so that the connecting tabs deform and the contact surfaces contact the electric wire when the slider is slid. The connecting tabs include burrs that are produced during processing of the metal sheet. The burrs protrude from the contact surfaces toward the electric wire.

  • Publication number: 20220247109
    Abstract: A female terminal includes a terminal body and a slider displaced relative to the terminal body. The terminal body includes a connecting tab deformable in a pressing direction crossing an inserting direction in which an electric wire is inserted and contactable with the electric wire. The slider is slidable between separated and overlapping positions. The slider includes a narrow portion that protrudes inward and has a less inner dimension in the pressing direction, and a wide portion in front of the narrow portion with respect to the inserting direction and has a greater inner dimension in the pressing direction than the narrow portion. The connecting tab contacts the electric wire when the narrow portion overlaps the connecting tab at the overlapping position. The slider includes a sloped guide surface that is angled at in front of the wide portion to spread further than the wide portion toward the front.
