12. The adapter as recited in claim 9, wherein: a thrust spring (16) is sleeved outside the connector body (11),
when the housing (13) of the connector pushes the second dust cap (24) to rotate in a direction away from the plug interface (212), the housing (13) retreats and compresses the thrust spring (16), and the body (11) pushes the first dust cap (14) to turn in a direction away from the body (11);
when the body (11) moves to a preset position of the inner member (22), the thrust spring (16) pushes the shell (13) to move along the plugging direction and is pressed on the outer side of the cantilever (221).
13. An adapter for interfacing with the waterproof and dust-proof connector of any one of claims 1-7, comprising:
the connector comprises a connector body (26), wherein two jackets (21) are arranged on two opposite sides of the connector body (26), the axes of the two jackets (21) are collinear, an inner member (22) is fixedly arranged on the connector body (26), the inner member (22) comprises two connecting parts, the two connecting parts respectively extend into the two jackets (21) correspondingly, each connecting part is provided with a cantilever (221), and the cantilever (221) is used for being buckled with a locking groove (119) on a body (11) of the connector; the inner member (22) is further provided with a sleeve (23), and the sleeve (23) is used for being inserted into the ferrule (12) of the connector.
14. A connector assembly, comprising: at least one waterproof and dustproof connector according to any one of claims 1 to 7 and an adapter according to any one of claims 8 to 13;
the connector extends into the outer sleeve (21) of the adapter, and the cantilever arms (221) of the adapter are buckled with locking grooves (119) on the body (11) of the connector.
