A rotary connector device includes a stator, a rotor and an electrical connector; the rotor including a rotor main body and a connector housing. The connector housing includes a first connector holder and a second connector holder. The second connector holder includes a second holder main body, a first wall, and a second wall. The first wall extends from the second holder main body along an axial direction parallel to the rotation axis. The second wall extends from the second holder main body along the axial direction and is coupled to the first wall.

An electrical extension cord device having an electrical port at one end and an electrical connector at an opposite end. The electrical port can include a cap or cover removable connected to the electrical port having an electrical plug or receptacle. The cap or cover and the electrical port have cooperating sealing surfaces to ensure watertight or waterproof sealing when the cap or cover is installed “on” the electrical port to prevent water or moisture reaching the plug.

An electrical port device having an electrical port and a cap or cover removable connected to the electrical port having a plug. A Y-shaped electrical cord or cable connects the electrical port to a pair of electrical receptacles. The Y-shaped electrical cord can include one electrical cord or cable section connected to the electrical port, a pair of electrical cord or cable sections connected to the pair of electrical receptacles, and a Y-shaped connector connecting the one electrical cord or cable section and the pair of electrical cord or cable sections. Further, the cap or cover and the electrical port have cooperating sealing surfaces to ensure watertight or waterproof sealing when the cap or cover is installed “on” the electrical port to prevent water or moisture reaching the plug.

In a lawn mower, one power receiving terminal is provided on a surface of the lawn mower, and the other power receiving terminal is disposed in a position where it sandwiches at least a part, such as the upper front portion, of a vehicle body with the one power receiving terminal. This configuration serves to suppress a situation in which moisture establishes electrical continuity between the pair of power receiving terminals.

A charging inlet for an electric vehicle (EV) includes a body defining a socket housing a conductive charging terminal, and a flange extending from the body and defining an interior channel in fluid communication with the socket. A valve assembly of the inlet includes a cap or adapter body removably attachable to the flange. The cap defines an interior space in communication with the interior channel of the flange with the cap attached to the flange. The valve assembly further includes at least one sealing valve, such as an umbrella valve, attached to an exterior of the cap and adapted to permit the passage of fluid from the interior space of the cap to an external environment.

A light bulb holder structure and a light bulb having same, in which the bulb cap of the light bulb holder is provided with a plurality of grooves in a tactful manner, and the depth of the grooves is greater than that of the external threads of the bulb cap, such that after the bulb cap is mounted on the light bulb and the light bulb is mounted on the light socket, the water accumulated between the light bulb holder structure and the light socket can be effectively discharged through the grooves. As a result, failure of the insulator (connector) on the light bulb holder structure caused by water accumulation can be avoided to a certain extent, thereby improving the reliability and safety of the light bulb.

A housing for an electrical connector includes a first set of orifices receiving a plurality of first pins, a second set of orifices receiving a plurality of second pins, a first draining device evacuating a fluid from the first set of orifices, and a second draining device evacuating a fluid from the second set of orifices. The second pins having a voltage higher than the first pins. The first set of orifices and the second set of orifices extend through the housing from a first interface of the housing toward a second interface of the housing in a connecting direction. The first draining device and the second draining device are isolated from each other and prevent fluid communication between the fluid from the first set of orifices and the fluid from the second set of orifices.

An electrical port device having an electrical port and a cap or cover removable connected to the electrical port having a plug. The cap or cover and the electrical port have cooperating sealing surface to ensure a tight waterproof sealing when the cap or cover is installed on the electrical port to prevent water or moisture reaching the plug.

A configuration is adopted in which a terminal module includes a voltage detection terminal having a terminal connection part connected to an electrode terminal and a wire connection part connected to a wire, and a protector housing at least part of the voltage detection terminal, with two liquid draining parts each including a first extension part extending downward in the direction of gravity being provided between the terminal connection part and the wire connection part in the voltage detection terminal, and the protector having a housing part housing the liquid draining parts and accumulating liquid that travels along the first extension part.

Disclosed herein is a safety outlet. The safety outlet includes a casing having at least one hole into which a pin of a plug is inserted; and at least one drain pipe forming a drain channel for independently communicating the at least one hole and the outside of the casing; wherein the drain channel provided in the at least one drain pipe each serves as drain passage separated from each other, and the drain pipe is partitioned so as to maintain sealing between inside of the casing and the drain channel, wherein a contact portion connected to a power terminal arranged outside of the at least one drain pipe is provided in the at least one drain pipe.
