Female connector and connector assembly

A female connector for receiving and securing a male connector, the male connector comprising an outer surface and a groove recessed inwardly from the outer surface and extending circumferentially, the female connector comprising:

• a female connector housing being cylindrical and provided with a channel, the female connector housing being configured to receive and secure through the channel the male connector inserted into the female connector housing along an axial direction thereof, wherein the female connector housing is provided with a slot at a portion thereof which receives the male connector, the slot forming an accommodating portion in a circumferential direction of the female connector housing;
• a fastening member inserted into the slot of the female connector housing,
• wherein the fastening member has a blocking position and an unblocking position, and wherein the fastening member is movable within the slot between the blocking position and the unblocking position;
• and
• a resilient member resiliently connected between the female connector housing and the fastening member, wherein the resilient member is configured to apply a restoring force to the fastening member to move the fastening member toward the blocking position when the fastening member is in the unblocking position, wherein the resilient member provides the restoring force through elastic deformation;
• wherein the fastening member is provided with a blocking portion on an inner wall thereof, and wherein the blocking portion cooperates with the accommodating portion to enable the blocking portion of the fastening member to at least partially move through the accommodating portion to enter the channel when the fastening member is in the blocking position, or exit the channel when the fastening member is in the unblocking position.
