Electrical connector
An efficient removal operation of a signal transmission medium is enabled with a simple configuration. A lock mechanism having a latch lock part, which retains an inserted state of the signal transmission medium by engagement with the signal transmission medium inserted in an insulating housing, is provided with an unlock maintaining part, which retains the latch lock part at a detachment position in conjunction with an unlock operation. It is configured so that, when the latch lock part of the lock mechanism is to be detached from the signal transmission medium by the unlock operation, an unlock maintaining part, which is moved in conjunction with the unlock operation, causes the latch lock part to be retained in a state in which it is detached from the signal transmission medium, and the signal transmission medium is maintained in a removable state thereafter even without continuing the unlock operation so that the unlock operation is completed at first for example only with one hand, and the signal transmission medium can be removed thereafter.
1. An electrical connector comprising
a lock mechanism having a latch lock part that is engaged with part of a signal transmission medium inserted in an insulating housing and retains an inserted state of the signal transmission medium; and
an unlock mechanism that causes the signal transmission medium to be removable from the insulating housing by an unlock operation of moving the latch lock part of the lock mechanism from an engagement position to a detachment position with respect to the signal transmission medium, wherein
the unlock mechanism is provided with an unlock maintaining part that maintains the latch lock part at the detachment position in conjunction with the unlock operation,
the lock mechanism has a lock biasing member that retains the latch lock part at the engagement position with respect to the signal transmission medium, and unlock operating part that moves the latch lock part to the detachment position against the lock biasing member,
the unlock maintaining part has an unlock maintaining nail that is moved to a position at which the nail abuts the signal transmission medium in conjunction with the unlock operation,
the unlock maintaining nail is configured to be brought into contact with the signal transmission medium with a pressure by biasing force of the lock biasing member so as to retain the latch lock part at the detachment position, and
the lock biasing member has first and second elastic arm-shaped members that are elastically displaced in two directions, the two directions being in planes approximately orthogonal to an insertion direction of the signal transmission medium and being approximately orthogonal to each other.
2. The electrical connector according to claim 1 , wherein
the first elastic arm-shaped member of the lock biasing member is disposed to be elastically displaceable along a board-thickness direction of the signal transmission medium, and
the second elastic arm-shaped member of the lock biasing member is disposed to be elastically displaceable along a board-width direction of the signal transmission medium.
