A meter collar is an adapter that may be inserted between a meter socket box and the meter. The meter collar may include a housing that is provided with first contacts to facilitate a mechanical and electrical connection with utility-side contacts of the meter socket box and second contacts to facilitate a mechanical and electrical connection with customer-side contacts of the meter socket box.

A modular electronic device system includes an electronic device and a cover for the device that allows the device to be mechanically and electrically mounted to a stand or device adapter on the rear side of the cover. The cover or device adapter can be connectable to modularly attachable and removable accessory devices and can provide electrical ports for powering and operating the accessory devices. While mounted to a stand, power and data communications can be provided to the electronic device, cover, and accessory devices from the stand or an external source. The modular components of the system can be interchangeable to allow the system to be adapted to many different settings and use cases based on the types of components included as the accessory devices and based on the number of accessory devices used.

A power adapter includes a housing, an electronic assembly and a protective assembly. The housing has a receiving cavity, and the housing is provided with at least one heat dissipation hole penetrating to the receiving cavity. The electronic assembly comprises a plurality of electronic elements located in the receiving cavity. The protective assembly comprises a connection portion connected to an outer wall of the housing and extending outward, and a protective portion connected to an extension end of the connection portion, the protective portion is spaced apart from the housing. The projection of the protective portion toward the housing covers the heat dissipation hole. The protective portion of the power adapter may shield the heat dissipation hole to prevent external dust from falling into the receiving cavity through the heat dissipation hole. Heat dissipated by the electronic assembly may be dissipated out through the heat dissipation hole.

In an example embodiment a power adapter includes a shell, a plug assembly, an electronic assembly and a protective shield, wherein the plug assembly comprises a plug and a connector electrically connected to the plug. The electronic assembly comprises a transformer and an electronic element; and the protective shield is located inside a receiving cavity and encloses a protective cavity together with a cavity wall of the receiving cavity, the connector is located inside the protective cavity, the electronic assembly is located outside the protective cavity, and the protective shield is a protective shield made of an insulating material. The power adapter reduces the influence of strong electrical interference generated by the connector on the electronic assembly, so that the space in the receiving cavity can be fully utilized, thereby realizing the small volume setting of the shell.

A plug for communication signal conversion, the plug including a first connector for synchronous communication signals, a second connector for Ethernet communication signals, and a converter for synchronous to Ethernet communication signal conversion, connected at a first end to the first connector and at a second end to the second connector, wherein the first connector, the second connector and the converter are included within a plug housing, and the plug housing is sized and shaped for plugging into a connector receptacle for communications signals. Related apparatus and methods are also described.

A power supply adapter includes a base plate, an electrical connector assembly disposed on the base plate, a support frame, a circuit board, and a shell body. The electrical connector assembly includes a hot connector assembly, a neutral connector assembly, and a ground connector assembly. When the adapter is plugged into a two-prong socket, the ground connector assembly is grounded to the two-prong socket. The support frame covers the electrical connector assembly and is affixed to the base plate. The circuit board is disposed on the support frame and electrically coupled to the electrical connector assembly. The shell body covers the support frame and circuit board and is affixed to the base plate. The power supply adapter can used with two-prong sockets that lack a ground slot, and provides grounding test function after being plugged into the two-prong socket, making it safe and convenient to use.

A power adapter with a Lightning female socket includes a main body and a housing, a Lightning female socket and an adapter unit on the main body, the Lightning female socket being electrically connected to the adapter unit; the housing being provided with an opening communicated to the Lightning female socket, the housing being sleeved on an exterior of the main body, and making the opening correspond to the Lightning female socket; the adapter unit being capable of providing electrical energy directly or indirectly to the Lightning female socket and outputting voltage and current outwardly through the Lightning female socket. By designing a power adapter with a Lightning female socket, a charging device and system, communication with an external terminal device and charging to the outside is achieved through the Lightning female socket.

The present disclosure relates generally to an electrical adapter and, more particularly, to an adapter for electric vehicle charging system s. The adapter includes: a housing; a male connector at a first side of the housing which is structured to plug into an electric device; a female connector at a second side of the housing which is structured to plug into a charging system; and a controller which provides management functions to provide an electric charge to the electric device.

A connector includes a housing and a contact elongated in a frontward and rearward direction. The contact has a fixed portion fixed to the housing in a middle in the frontward and rearward direction, a first contact portion formed in a front end portion for coming into contact with a first circuit board, a second contact portion formed in a rear end portion for coming into contact with a second circuit board, and a deflective portion formed between the fixed portion and the second contact portion. The deflective portion is adapted to deflect when the second contact portion receives a force from the second circuit board.
