A terminal connector and an electric drive assembly, includes a terminal block and magnetic conductors arranged on a mounting part. The terminal block has a plurality of connecting terminals for transmitting three-phase electricity, and first connecting ends and second connecting ends of the connecting terminals extend out of the mounting part, so as to be electrically connected to a motor controller and a drive motor respectively. Therefore, the connecting terminals pass through a first coupling space of the magnetic conductor, so that an induced magnetic field generated by the connecting terminals is coupled to the magnetic conductor. At the same time, a second coupling space is arranged on an outer side of the mounting part, so that when the terminal connector is connected to the motor controller, the induction element may be arranged on an inner side of the second coupling space.

A compact connector that economically provides high signal integrity in a harsh environment, such as an automobile, which may be a right-angle connector. The connector may include a contact carrier position assurance component (CCPA) that ensures that a contact carrier is and remains latched in a designed position, which improves signal integrity. The CCPA may retain the mating interface portions or the contact carrier in the desired location relative to the mating direction, but may be narrow and fit into a narrow slot perpendicular to the mating direction of the connector so as to enable the connector to extend only a small distance in the mating direction beyond the mating face of a mating connector. Such a connector may also have a connector position assurance device that facilitates reliable operation of the connector.

A connector includes: a terminal to be connected to an electric wire; a housing in which the terminal is housed; and a heat transfer member having a tubular shape in at least a part thereof, and having a tube into which the terminal is inserted. The heat transfer member has an inner tubular surface of the heat transfer member in contact with the terminal, an outer tubular surface in contact with the housing, and a fin structure for heat dissipation at a position not in contact with the housing.

A quick electrical-connecting structure for a high-voltage high-frequency pulse environment relates to the technical field of high-voltage high-frequency electrical engineering. The quick electrical-connecting structure includes a plug, a socket, and a cable, where the cable is connected to the socket through the plug; the plug and the socket internally enclose an annular cavity surrounding the cable; and a protective fluid is filled in the annular cavity. By charging a protective fluid to the annular cavity in the plug and the socket, a high-intensity insulating fluid protective layer is maintained around a connecting position of the cable in the annular cavity. Therefore, the quick electrical-connecting structure lowers an internal humidity, and can effectively reduce corona discharge and creepage.

High speed, high density I/O connector assemblies. An I/O connector assembly includes a cage and a heat dissipation member. The cage includes a top wall having an opening and a channel accessible from the front. The heat dissipation member includes a base disposed at the top of the cage, multiple sections separated by gaps, and a contact portion protruding from the base in a first direction into the channel through the opening of the top wall. Each section includes fins protruding from the base in a direction opposite to the first direction. The heat dissipation member comprises a layer of micro thermal interface material at a contact interface. Techniques described herein, including the structure and material composition of components, can provide sufficient heat dissipation to enable high speed, high density I/O connector assemblies that nonetheless can be economically manufactured and meet the dimensional requirements of an OSFP-XD standard.

In an electronic device, a heat sink is supported to be movable in a first direction relative to a receptacle shell. A contact surface of a plug shell and a heat releasing surface of the heat sink are formed as inclined surfaces. A pressing member is disposed between the heat sink and the receptacle shell. The receptacle shell includes a guide portion (cam groove) configured to regulate movement of the heat sink in a negative second direction when the heat sink is at a position in a positive first direction relative to the receptacle shell, and to regulate movement of the heat sink in a positive second direction when the heat sink is at a position in a negative first direction relative to the receptacle shell. The heat sink includes a guided portion (columnar protrusion) configured to be guided by the guide portion (cam groove) on the receptacle shell.
