Connector assembly with reliable locking structure

A connector assembly, comprising:

• a connector comprising an insulating body and a plurality of conductive terminals, the insulating body comprising an insulating body portion, a plurality of mating end portions extending from the insulating body portion, and an accommodating space formed by the plurality of mating end portions;
• each mating end portion defining a first mating space for receiving a corresponding conductive terminal;
• and
• a locking structure comprising a body portion, a plurality of holding arm portions and a resisting portion;
• the body portion being received in the accommodating space and configured to receive a high voltage interlock terminal;
• each holding arm portion being configured to be fixed to a corresponding mating end portion;
• the locking structure comprising a pre-locking position and a locking position which are relative to the connector;
• wherein the resisting portion is configured such that:
• when the locking structure is located at the pre-locking position, the resisting portion is located outside a corresponding first mating space;
• when the locking structure is in the locking position, at least part of the resisting portion protrudes into the corresponding first mating space.
