A connector-equipped electrical wire includes a connector housing in which a cavity is formed and a terminal-equipped electrical wire inserted into the cavity. In a first state before full fastening by a full fastening portion is achieved and in which a first cavity communicates with a second cavity corresponding thereto, a first portion of the terminal-equipped wire is configured to pass through the second cavity and fit into the first cavity, and a second portion of the terminal-equipped wire is fitted into the second cavity. In a second state in which full fastening by the full fastening portion is achieved, when observed in an axial direction of the cavity, a regulatory surface of an inner surface of the second cavity approaches closer to the second portion than when in the first state.

A modular connector system with components that can be economically assembled to provide high signal integrity in a harsh environment, such as an automobile. In some connectors, electrical conductors serving as signal conductors may be at least partially encircled by a conductive sheet formed into a tube. The tube may be formed by joining opposite edges of the sheet with tab portions extending from the edges. The tab portions may be bent to extend radially outwards from the cavity and crimped together, providing mechanical integrity to the shield, as well as a tab that polarizes the shield to block incorrect insertion into an insulative housing and can engage with components in the insulative housing to latch the shield in the housing. Other disclosed techniques economically and stably position electrical conductors, which may serve as signal terminals relative to ground structures, electrically and mechanically connect shields, or compensate for impedance variations.

A heating element for a mating interface of an electrical connector, a method of manufacture and an connector assembly. The heating element comprises a cavity configured to receive the mating interface along a receiving direction, a carrier body at least sectionally arched around the cavity, and a heating wire held by the carrier body, wherein the heating wire extends circumferentially with respect to the receiving direction in a meandering pattern. In contrast to heating elements with helically coiled wires that have to follow a uniform path, the meandering pattern allows the heating wire to be routed in a way that can be easily adapted to any irregular geometry surrounding the mating interface. This facilitates the integration of the heating element in the electrical connector.
