  • Publication number: 20140322952
    Abstract: In an electrical connector, a latch claw is provided at a nearer side than a lock claw in a fitting direction of a connector fitting portion to a power receiving connector. While the latch claw is retracted into the connector fitting portion, the latch arm swings to release the latching between a latch piece and a second latch groove portion. The latch arm includes a protrusion 131A that releases the latching between the second latch groove portion and a hold latch piece of the lock-release hold portion when the second latch groove portion and the latch piece latch together.

  • Publication number: 20140302695
    Abstract: An object is to provide a connector which can prevent a foreign object from contacting an insert and which can reduce insertion force for inserting the insert into a mating terminal. A connector includes a rod-shaped insert to which a mating terminal is fitted from front, a housing having a tube-shaped terminal receiving portion arranged to receive the insert, an insulating contact prevention member arranged between a peripheral wall of the terminal receiving portion and the insert so as to slide along a terminal fitting direction of the mating terminal and the insert, and an elastic member which exerts a force on the contact prevention member toward the front end side of the insert. The contact prevention member includes a tapered face slanted radially-outward towards the rear side of the terminal fitting direction.

  • Publication number: 20140242818
    Abstract: A connector fitting structure is composed of a power-feed connector and a power-receiving connector. The power-feed connector includes: a case; a connector main body having a power-line terminal; a lever for moving the connector main body forward and backward; and a lock arm for locking both cases with each other by engaging with a case of the power-receiving connector. In the connector fitting structure, while both cases are locked with each other and the connector main body is positioned in a front position, the connector main body is fitted with a connector main body of the power-receiving connector. Further, while both cases are locked with each other and the connector main body is positioned in a rear position, the power-line terminal is in contact with a power-line terminal of the power-receiving connector.

  • Publication number: 20140051277
    Abstract: A half fitting prevention connector includes a cylindrical case, a connector body, a lever, and a release lever. The release lever has a lock hole. An electromagnetic coil has a plunger. The plunger is arranged so as to face a microswitch. The electromagnetic coil is excited by connection between the signal terminal of the connector body and a signal terminal of a mating connector, and thereby moving the plunger toward the microswitch. The release lever is rotatable so that the plunger can enter the lock hole to press the microswitch in a state that the connector body is completely fitted with the mating connector and the plunger cannot enter the lock hole in a state that the connector body is half fitted with the mating connector.

  • Patent number: 8439699
    Abstract: A lever type electrical connector has a case. A connector terminal is provided in the case so as to be slidable in a first direction, and is operable to engage with a mating connector terminal by being moved in the first direction. A handle is connected with the connector terminal. A first lever is pivotably attached to the case, and is connected to the handle. The first lever is operable to be moved so as to move the handle in the first direction. A first lock arm is pivotably attached to the case. A first end of the first lock arm is operable to be come in contact with the mating connector terminal. A second end of the first lock arm opposite to the first end is operable to be disengaged from the handle when the first end is urged from the mating connector terminal. The second end is operable to be engaged with the handle so as to prevent the handle from moving in the first direction when the first end is not urged from the mating connector terminal.
