The present invention relates to a protection apparatus (100) for protecting an electrical circuit. The protection apparatus comprises a thermal protection device (10) for interrupting the electrical circuit at a specific temperature and also an insertion slot (20) for receiving a fuse (21) for interrupting the electrical circuit at a specific current intensity in the electrical circuit. The thermal protection device (10) and the insertion slot (20) are connected in series in the electrical circuit (40), wherein the insertion slot and the thermal protection device are arranged adjacently.

A device may include a housing including a face plate. A device may include a plurality of sensing cores each configured to receive a current flow through a center cavity, the current flow defining a current flow direction through the center cavity, wherein the current flow direction is parallel to the face plate.

A locking electrical outlet assembly includes at least one electrical plug that has a pair of blades and an outlet housing is provided that is positioned in a wall. A pair of sockets is each rotatably positioned in the outlet housing. Each of the sockets is rotatable between a first position and a second position, and each of the sockets is biased to rotate into the second position. A pair of locking units is each movably coupled to a respective one of the sockets for releasably retaining the sockets in the first position. Each of the locking units in the respective socket disengages the outlet housing when the electrical plug is plugged into the respective socket. A plurality of contacts is coupled to the outlet housing and each of the terminals on the sockets engages respective ones of the contacts when the sockets are rotated into a second position.

A socket connector includes an insulating housing, a sliding block, a resilient element, a detection terminal assembly assembled to a rear end of the insulating housing, a connection terminal assembly assembled to the rear end of the insulating housing, at least one ground element, and an outer shell surrounding the insulating housing. A top of the insulating housing has a restricting groove. A rear of the restricting groove extends rearward to form a sliding groove. At least one side surface of the insulating housing is recessed inward to form at least one ground groove. A rear of a bottom of connecting space extends downward and rearward to form a holding groove. The sliding block is mounted in the sliding groove. The at least one ground element is received in the at least one ground groove. The resilient element is assembled to a top of the insulating housing.

An alternating current/direct current input device includes an appliance input socket and an information and communications technology (ICT) device. The ICT device is powered by the appliance input socket. The appliance input socket includes a ground contact, a positive electrode contact, a negative electrode contact, and a signal switch. A contact depth of the signal switch in the appliance input socket is less than a contact depth of the positive electrode contact or the negative electrode contact in the appliance input socket. The signal switch is configured to generate a control signal when a direct current connector is separated from the appliance input socket. The control signal can be used to enable the ICT device to disconnect the appliance input socket from a conductive electrode of the direct current connector after the ICT device enters a no load state.

A plug connector part includes a plug housing that has at least one plug-in portion that can be connected to a mating plug connector part by plugging in an insertion direction so as to contact the plug connector part electrically with the mating plug connector part; and a compensation device arranged on the plug housing, the compensation device including: a housing; a carrier element connected to the plug housing and arranged on the housing; and a spring element that biases the carrier element with respect to the housing, wherein the carrier element is movable relative to the housing by way of resilient deformation of the spring element.

A heat destructive disconnecting switch, comprising a first conductive member, a second conductive member, a movable conductive member, an overheating destructive member, an operating component, and a second elastic member. The movable conductive member enables electrical conduction with the first conductive member and the second conductive member. A first elastic member having a first spring and a second spring which are compressed and provided with a first elastic force, and the second elastic member is provided with a second elastic force. When the overheating destructive member is destructed due to overheating, the first elastic force is diminished or vanished, which causes the second elastic force to be larger than the first elastic force and forces the movable conductive member to disconnect from current conducting state between the first conductive member and the second conductive member, thereby achieving a protective effect from overheating.
