20150064954 | CONNECTOR DEVICE - A connector device comprises a connector and a mating connector. The connector is mateable with the mating connector and removable from the mating connector. The mating connector includes a mating primary terminal and a mating secondary terminal. The connector includes a housing, a sub-connector, a first operation member and a second operation member. The housing holds a primary terminal while the sub-connector holds a secondary terminal. When the first operation member is operated, the housing is moved, and the primary terminal is connected to the mating primary terminal. When the second operation member is operated, the sub-connector is moved, and the secondary terminal is connected to the mating secondary terminal. | 03-05-2015 |
20150372420 | CONNECTOR - A connector is receivable an object along a receiving direction. The connector ejects the object along an ejecting direction opposite to the receiving direction. The object has a mating terminal, a pressed portion and a regulated portion. The connector comprises a holding member, a terminal and an operation member. The operation member is supported by the holding member so as to be movable between a first position and a second position. The operation member includes a press portion and a regulating portion. When the operation member is operated to be moved from the first position toward the second position, the press portion presses the pressed portion in the ejecting direction to move the object in the ejecting direction. At the latest until the operation member reaches the second position, the regulating portion enters into an ejecting path to regulate a movement of the regulated portion in the ejecting direction so that the regulating portion prevents the object from being released off the connector in the ejecting direction. The ejecting path is a movement path on which the regulated portion passes when moved in the ejecting direction. | 12-24-2015 |
20160056573 | CONNECTOR DEVICE - A connector device comprises a connector and a mating connector connectable with each other. The mating connector comprises a mating primary terminal and a mating secondary terminal. The connector comprises a primary terminal, a secondary terminal, an operation member and a push-back mechanism. The operation member changes its state from an initial state to a second state via a second state. When the state of the operation member is changed to the first state, the primary terminal is connected to the mating primary terminal. When the state of the operation member is changed to the second state, the secondary terminal is connected to the mating secondary terminal. When the state of the operation member is changed to the first state, the push-back mechanism applies a push-back force to the operation member to change the state of the operation member back toward the initial state. | 02-25-2016 |
