Abstract

A charging connector in accordance with the present invention includes: connector cases that house a connector fitting portion; a locking arm in which a locking claw retractable from an outer peripheral surface of the connector fitting portion is provided at a tip, and that rocks centering around a shaft core between a locking position and a releasing position; and a coil spring that biases the locking arm toward the locking position. The locking arm includes a lock releasing portion that is inserted into a through hole formed in the connector cases, and with which the locking arm can be operated to the releasing position from an outside of the connector cases.

First claim

The invention claimed is:

1. A charging connector comprising:
a connector case that houses a connector fitting portion that is fitted to a counterpart connector;
a locking arm in which a locking claw retractable from an outer peripheral surface of the connector fitting portion is provided at a tip, and that rocks centering around a rocking shaft between a locking position where the locking claw engages with the counterpart connector and a releasing position where engagement of the counterpart connector and the locking claw is released; and
a biasing member that biases the locking arm toward the locking position, wherein
the locking arm includes a lock releasing portion that is inserted into a through hole formed in the connector case, and with which the locking arm can be operated to the releasing position from an outside of the connector case with the locking arm rocking centering around the rocking shaft and supported by the rocking shaft, and
the locking arm is pivotally supported around the through hole via the lock releasing portion.

2. A charging connector comprising:
a connector case that houses a connector fitting portion that is fitted to a counterpart connector;
a locking arm in which a locking claw retractable from an outer peripheral surface of the connector fitting portion is provided at a tip, and that rocks centering around a rocking shaft between a locking position where the locking claw engages with the counterpart connector and a releasing position where engagement of the counterpart connector and the locking claw is released; and
a biasing member that biases the locking arm toward the locking position, wherein
the locking arm includes a lock releasing portion that is inserted into a through hole formed in the connector case, and with which the locking arm can be operated to the releasing position from an outside of the connector case with the locking arm rocking centering around the rocking shaft and supported by the rocking shaft, and
the lock releasing portion is configured by the rocking shaft of the locking arm.

3. A charging connector comprising:
a connector case that houses a connector fitting portion that is fitted to a counterpart connector;
a locking arm in which a locking claw retractable from an outer peripheral surface of the connector fitting portion is provided at a tip, and that rocks centering around a rocking shaft between a locking position where the locking claw engages with the counterpart connector and a releasing position where engagement of the counterpart connector and the locking claw is released; and
a biasing member that biases the locking arm toward the locking position, wherein
the locking arm includes a lock releasing portion that is inserted into a through hole formed in the connector case, and with which the locking arm can be operated to the releasing position from an outside of the connector case with the locking arm rocking centering around the rocking shaft and supported by the rocking shaft, and
a cap to close the through hole is applied to the through hole.

4. The charging connector according to claim 3 , wherein a latching portion is provided at either one of the through hole and the cap, and a latched portion to which the latching portion is latched is provided at the other.
