First terminal module with improved shielding effect and electrical connector having the same

An electrical connector, comprising:

• a first terminal module, the first terminal module, comprising:
• a first conductive housing, the first conductive housing comprising a first main body portion, a first mating portion extending from one end of the first main body portion, and a first extension portion extending from another end of the first main body portion;
• a first conductive cover plate, the first conductive cover plate being located on an inner side of the first conductive housing;
• and
• a first terminal assembly, the first terminal assembly comprising a first insulating fixing block and a plurality of first signal terminals fixed to the first insulating fixing block;
• the first terminal assembly being at least partially located between the first conductive housing and the first conductive cover plate;
• each first signal terminal comprising a first middle portion, a first signal elastic arm portion extending from one end of the first middle portion, and a first tail portion extending from another end of the first middle portion;
• the first signal elastic arm portion comprising a first signal contact portion configured to be in contact with a mating module;
• the first signal terminals being not in contact with the first conductive housing;
• wherein the first conductive housing covers the first signal elastic arm, the first middle portion and the first tail portion of the first signal terminal along a length direction of the first signal terminal;
• and
• a second terminal module, the second terminal module comprising:
• a second conductive housing, the second conductive housing comprising a second main body portion, a second mating portion extending from one end of the second main body portion, and a second extension portion extending from another end of the second main body portion;
• a second conductive cover plate, the second conductive cover plate being located on an inner side of the second conductive housing;
• and
• a second terminal assembly, the second terminal assembly comprising a second insulating fixing block and a plurality of second signal terminals fixed to the second insulating fixing block;
• the second terminal assembly being at least partially located between the second conductive housing and the second conductive cover plate;
• each second signal terminal comprising a second middle portion, a second signal elastic arm portion extending from one end of the second middle portion, and a second tail portion extending from another end of the second middle portion;
• the second signal elastic arm portion comprising a second signal contact portion configured to contact the mating module;
• the second signal terminals being not in contact with the second conductive housing;
• wherein the second conductive housing covers the second signal elastic arm portion, the second middle portion and the second tail portion of the second signal terminal along a length direction of the second signal terminal;
• and
• wherein the first conductive housing of the first terminal module is in contact with the second conductive housing of the second terminal module to form a mating slot between the first conductive housing and the second conductive housing;
• the first signal contact portion of the first terminal module protrudes into the mating slot from one side, and the second signal contact portion of the second terminal module protrudes into the mating slot from an opposite side;
• the mating slot is configured to receive the mating module;
• the mating module is in contact with the first signal contact portion and the second signal contact portion.
