[0002] Electric connectors are components used to connect different parts of an electrical circuit, primarily for transmitting electrical signals or power. They are widely used in electronic devices, communication equipment, automobiles, household appliances, and other fields. Electric connectors come in a variety of types, including plugs, sockets, wiring terminals, pin headers, and female headers.

[0003] Most connectors on the market currently adopt a single structure, which results in the need to occupy a large amount of space on the circuit board when fixing the connector. Especially in cases where multiple connectors need to be fixed, the occupied area at the end of the circuit board is further increased, which easily leads to waste of circuit board space. With the miniaturization and integration of electronic devices, higher requirements are placed on connectors, i.e., to minimize the occupied space while ensuring reliable connection and improving the space utilization of the circuit board.

Each connector module includes an insulator, a plurality of conductive terminals fixed to the insulator, and a metal shell surrounding the insulator. The insulator includes a base and a cantilever-shaped tongue plate extending forward from the base. Each conductive terminal includes a contact portion fixed to the tongue plate and at least partially exposed outside the tongue plate, a fixed portion connected to the contact portion and fixed in the base, and a mating portion connected to the fixed portion and extending outward beyond the insulator. The insulator and the metal shell collectively form a plug-in space for mating with a matching connector and a plug-in port at the front. The outer insulating cover and the outer metal cover form a space for the at least two connector modules.
