A connector housing comprises an inner housing including a rear housing, and a first sub housing and a second sub housing each formed integrally with the rear housing. The first sub housing is sized to accommodate a first cable assembly, and includes a rear end connected to a front side of the rear housing. The second sub housing is sized to accommodate a second cable assembly and a third cable assembly. A rear end of the second sub housing is connected to the front side of the rear housing. The first sub housing and the second sub housing are arranged side by side.

A connector sealing assembly includes an outer housing defining a plurality of seal mounting portions. A cable seal of the assembly is mounted on a cable seal mounting portion of the plurality of seal mounting portions. The cable seal is sized and located to form a seal between the outer housing and a cable extending into the outer housing. A housing seal of the assembly is mounted on a housing seal mounting portion of the plurality of seal mounting portions. The housing seal is sized and located to form a seal between the outer housing and a mating housing of a mating connector.

A connector housing assembly includes an inner housing, a cable seal and a housing seal. The inner housing defines a plurality of terminal mounting holes for fixedly mounting a plurality of terminals. The cable seal is installed in the inner housing and is adapted to form a seal between the inner housing and a cable extending into the inner housing. The housing seal is sleeved on an outer side of the inner housing and is adapted to form a seal between the inner housing and a mating housing of a mating connector.

A power extension cord socket includes a first socket device and a control device. The first socket device has plural AC power sockets and AC power switches, and each AC power socket is provided for plugging an external load to forward mains electricity, and each AC power switch is connected to the respective AC power socket for controlling the open circuit or closed circuit of the AC power socket. The control device is coupled to the mains electricity and electrically connected to the first socket device. The control device has a leakage detection processor and a leakage power-off switch and uses the leakage detection processor to detect a current usage status of the first socket device, and turns on the leakage power-off switch in an abnormal status to stop each AC power socket from forwarding the mains electricity to the load.
