  • Patent number: 11588259
    Abstract: A battery terminal includes a terminal main body and a protector to be mounted to the terminal main body, wherein the terminal main body includes an operating section for clamping and tightening the battery post, and the protector includes a movable section provided with a contact section to be brought into contact with the upper surface of the battery main body, and a displacement section to be freely displaced between a covering position for covering the operating section and a retracted position with an external force applied on the contact section, wherein in the retracted position, the displacement section is retracted from the covering position, and wherein the displacement section is displaced to the retracted position by pressing the contact section against the upper surface of the battery main body so that the access to the operating section is allowed.

  • Publication number: 20220021092
    Abstract: A battery terminal includes a terminal main body and a protector, wherein the terminal main body includes clamping sections for clamping the battery post, opposed sections and an operating section, the opposed sections being continuous with the clamping sections, wherein the operating section causes the opposed sections to approach each other, wherein the protector includes an elastic section provided with a contact section to be brought into contact with the upper surface of the battery main body, and a displacement section provided so as to be freely displaced between an introduction position and a retracted position, wherein in the introduction position, a tightening operation by the operating section is limited, and wherein the displacement section is displaced from the introduction position to the retracted position by pressing the contact section against the upper surface of the battery main body so that the tightening operation is allowed.

  • Patent number: 9941086
    Abstract: Provided is a fusible link unit (electrical component unit) including a fusible link (electrical component), a battery terminal fixed to an electrode post (electrode) of a battery, and a support member formed as a different body from the battery terminal and fixed to the battery, the support member supporting the fusible link (electrical component), in which the fusible link (electrical component) includes a main link body (main electrical component body) and a power supply terminal made of conductive metal to be exposed from the main link body (main electrical component body) and electrically connected to the electrode post (electrode) through the battery terminal, and the support member supports the main link body (main electrical component body) such that the main link body extends in an orthogonal direction substantially orthogonal to an installation surface portion.

  • Patent number: 9653723
    Abstract: A battery terminal includes a terminal main body provided in opposed plates thereof as a pair, formed by folding approximately in a U shape a strip plate made of a conductive metal, respectively with electrode insertion holes in which a rod-like electrode projecting from a terminal attaching surface in a battery is sequentially inserted, and formed to extend toward an outer edge of the terminal attaching surface at time of being connected to the rod-like electrode, and a joint joining the pair of the opposed plates in a state in which the opposed plates surface-contact and overlap each other on an opposite side of a folded part as seen from the electrode insertion hole.
