The present disclosure relates to an electrical power transmission and outlet system. The electrical power transmission and outlet system may include an electrical power transmission and outlet device and an external power storage unit. The electrical power transmission and outlet device may include a housing having an opening for receiving an external plug, a connector in the housing for connecting with the external power storage unit; and a plurality of electrical conductors in the housing connected to the connector. When the external plug is inserted into the opening, the conductors are electrically connected to the external plug and disconnected from the connector, and when the external plug is pulled out of the opening, the conductors are electrically disconnected from the external plug and reconnected to the connector.

A cap opening and closing structure is configured such that a surface of an inlet damper in a rotation axis direction and a side surface of a first supporting unit keep facing each other while the cap rotates. The surface is provided with a convex portion, and the side surface is provided with a concave portion, and the convex portion and the concave portion are engaged with each other in an open position. An inlet damper spring biases the convex portion so as to engage with the concave portion in the open position and to contact the facing side surface in a non-engagement state between the convex portion and the concave portion. Two inclined surfaces of the convex portion facing each other in a rotation direction contact respective ends of the concave portion in the open position.

An electrical power transmission and outlet system. The electrical power transmission and outlet system may include an electrical power transmission and outlet device and an external power storage unit (1110). The electrical power transmission and outlet device may include a housing (1060) having an opening for receiving an external plug (1220), a connector (1070) in the housing (1060) for connecting with the external power storage unit (1110); and a plurality of electrical conductors in the housing (1060) connected to the connector (1070). When the external plug (1220) is inserted into the opening, the conductors are electrically connected to the external plug (1220) and disconnected from the connector (1070), and when the external plug (1220) is pulled out of the opening, the conductors are electrically disconnected from the external plug (1220) and reconnected to the connector (1070).

There is provided a light bulb socket comprising: a substantially cylindrical socket housing defining an open end for the insertion of a light bulb connector therein, the cylindrical socket housing defining a coaxial axis, the socket housing defining an inner comprising screw threading for screw-type engagement of a screw-type light bulb and opposing pair of bayonet channels, each bayonet channel comprising an insertion channel portion parallel to the coaxial axis and terminating in an perpendicular engagement channel for the inline insertion and twisting engagement of opposing bayonet pins of a bayonet-type bulb therein; a deflectable safety plate retained within the socket housing, the deflectable safety plate deflectable between a default position towards the open end of the socket housing and a deflected position away from the open end; and electrodes within the socket housing, the electrodes comprising: a central electrode; and a pair of lateral electrodes adjacent the central electrode.

By a simple configuration, contact members can be well retained with a housing in a mutually opposed state, and productivity can be improved. When the contact members in the mutually opposed state are to be attached to the housing, a contact retainer prepared by molding in advance is used by disposing the contact retainer in part of the contact opposed region. As a result, the contact members are stably retained in the mutually opposed state even in injection molding molds. Even in a case in which the contact members normally cannot be retained in the mutually opposed state in the injection molding molds, the housing and the contact members can be integrally molded by well retaining the contact members in the mutually opposed state by using the contact retainer and a contact retainer auxiliary and executing an injection molding process.

In at least one embodiment, a connector assembly for being positioned on a vehicle is provided. The connector assembly includes first and second connector portions. The first connector portion defines a first and second channels. Each of the first and second channels are positioned on opposite sides of the first connector portion. The first connector portion includes a first contact member and a second contact member. The second connector portion includes a first shutter and a second shutter positioned on an outer surface of the second connector portion. Each of the first shutter and the second shutter are configured to receive the first contact member and the second contact member, respectively. Each of the first and second shutters pivot about an axis in response to receiving the first contact member and the second contact member, respectively, to enable the first connector portion to mate with the second connector portion.

A connector protection device includes a base plate, two connectors assembled at the base plate, a pivot shaft assembled at the base plate, a protection cover, a torsion spring assembled at the pivot shaft and a pressing button. The protection cover includes a connecting portion assembled at the pivot shaft and two covers, wherein each of the covers corresponds to one of the connectors. The torsion spring has one end abutting against the base plate and the other end abutting against the connecting portion. The pressing button is provided between the two covers, and has one end abutting against the connecting portion. The torsion spring applies a force on the connecting portion such that the covers tilt above and cover the connectors. When pressed downwards, the pressing button pushes the connecting portion to rotate in reverse, further driving the covers to rotate in reverse to expose the connectors.

An electrical device includes a shutter support structure having a return position, at least one blocking position and an open position. A first shutter element is configured to rotate about a first dimensional axis within a predetermined angular range while being translated in two-dimensions between the return position to the open position, each of the two dimensions being orthogonal to the first dimensional axis. A second shutter assembly includes a second shutter element coupled to the first shutter element, the first shutter element allowing the second shutter portion to move in a first direction parallel to the first dimensional axis when the first shutter element is in the open position, the first shutter element being configured to drive the second shutter element in a second direction parallel to the first dimensional axis when the first shutter element is being translated into the return position.

An electrical connector includes a main body, a first cover, and a second cover. The main body includes a first connection portion, a wire inlet portion, and an accommodating space between the first connection portion and the wire inlet portion. The first cover is pivotally connected to the first connection portion to be rotatable relative to the main body between a first position and a second position. When the first cover is at the first position, the accommodating space is opened for installation. When the first cover is at the second position, the first cover at least partially closes the accommodating space for protection. The second cover is connected to the first cover and separably encloses a wire inlet hole with the wire inlet portion. The second cover is movable relative to the wire inlet portion to adjust the size of the wire inlet hole.

There is provided a connector configured by a first connector and a second connector which are fitted and electrically connected to each other. The first connector includes a projecting portion extending toward the second connector. The second connector includes: a terminal; and a cap configured to cover a front surface of the terminal and having a folding mechanism. A cover portion of the cap includes: a first cover portion provided with a rotating shaft; a second cover portion adjacent to the first cover portion and provided with a rail pin; and a connection portion that rotatably connects the first cover portion and the second cover portion to each other. The rail pin is configured to move along a rail in response to the contact portion being pressed and/or released by the projecting portion.
