  • Publication number: 20200067222
    Abstract: A terminal has a central axis parallel to a direction in which the terminal is inserted into a mating terminal and includes a contact part and an intermediate part. The contact part includes: four springs that make contact with the mating terminal and are equally spaced along a circumferential direction around the central axis; and a joint part that makes the four springs join together, the contact part being formed by bending a first electrically conductive plate. The intermediate part includes a tubular part, and is disposed adjacent to the contact part and formed by bending a second electrically conductive plate. The plate thickness of a spring forming portion of the first electrically conductive plate, the spring forming portion forming the springs, is smaller than the plate thickness of a tubular part forming portion of the second electrically conductive plate, the tubular part forming portion forming the tubular part.

  • Patent number: 9614315
    Abstract: The electrical connector includes: a housing having a terminal space therein; and a connector terminal to be housed in the terminal space. The connector terminal includes: a terminal body operable to be inserted into the terminal space; and a lance formed at the terminal body for preventing the terminal body from being pulled out of the terminal space. The terminal space includes a pair of walls. The lance includes: a first elastically deformable portion outwardly extending from the terminal body; and a second elastically deformable portion being continuous with a distal end of the first portion, and being disposed outwardly of the first portion relative to the terminal body. A gap is formed between the terminal body and each of the walls, and the first and second portions can pass the gap in an elastically deformed condition.

  • Patent number: 9564708
    Abstract: An electrical connector including: a housing including an outer peripheral part; and a lock arm provided with the outer peripheral part. The lock arm is swingable like a seesaw and detachably engages with a locking part provided with another housing of a mating connector. The lock arm extends along a coupling direction toward the mating connector. A pair of side wall parts are provided with the outer peripheral part such that the pair of side wall parts oppose to each other from both sides of the lock arm. An elastic support mechanism for swingably supporting the lock arm is provided between a lower face part of the lock arm and inner side faces of the pair of side wall parts.

  • Patent number: 9502804
    Abstract: An electrical connecting module includes a first electrical connector, and a second electrical connector, both being coaxially fittable into each other. The first electrical connector includes a first housing, and a contact terminal housed in a terminal space formed in the first housing. The second electrical connector includes a second housing and a cylindrical terminal fixed in the second housing, the cylindrical terminal being fabricated by joining opposite ends of an electrically conductive sheet to each other in a manner such that the sheet defines a circular cross-section. The contact terminal includes an elastic contact piece contacting an inner surface of the cylindrical terminal. Each of the housings includes a positioning section for causing the elastic contact piece to contact the cylindrical terminal at the inner surface other than an area through which the opposite ends of the electrically conductive sheet are joined to each other.
