Electrical connector and connector assembly with improved solder accommodating hole

A connector assembly, comprising:

• an electrical connector, the electrical connector comprising:
• a body;
• and
• a first terminal module at least partially disposed in the body, the first terminal module comprising a first insulating block, a plurality of first conductive terminals fixed to the first insulating block, a first cable electrically connected to the first conductive terminals, and a first shielding plate cooperating with the first conductive terminals;
• the plurality of first conductive terminals comprising a first ground terminal, a first signal terminal, a second signal terminal, and a second ground terminal;
• the first signal terminal and the second signal terminal being both located between the first ground terminal and the second ground terminal;
• wherein the first cable comprises a first core, a second core, a first insulating layer wrapping around the first core, a second insulating layer wrapping around the second core, and a first shielding layer located outside the first insulating layer and the second insulating layer;
• the first core is electrically connected to the first signal terminal;
• the second core is electrically connected to the second signal terminal;
• wherein the first shielding plate comprises a first end protrusion, the first end protrusion is provided with a first solder accommodating hole, the first shielding layer is exposed in the first solder accommodating hole, and the first solder accommodating hole is configured to accommodate solder to fix the first shielding layer to the first end protrusion;
• and
• a mating connector, the mating connector comprising:
• a mating insulating body, the mating insulating body comprising a plurality of wall portions and a mating slot defined by the plurality of wall portions;
• the plurality of wall portions comprising a first wall portion, a second wall portion disposed opposite to the first wall portion, a first connecting wall portion connecting one side of the first wall portion and one side of the second wall portion, and a second connecting wall portion connecting another side of the first wall portion and another side of the second wall portion;
• the mating slot being configured to at least partially receive the electrical connector along a mating direction;
• a plurality of mating terminals, the mating terminals being at least partially disposed in the mating insulating body;
• each mating terminal comprising an elastic mating arm extending into the mating slot and configured to be in contact with the first contact surface of the first conductive terminal of the electrical connector;
• and
• a metal shell, the metal shell at least partially covering the mating insulating body;
• the metal shell comprising a first side wall, a second side wall disposed opposite to the first side wall, a first connecting wall connecting one side of the first side wall and one side of the second side wall, and a second connecting wall connecting another side of the first side wall and another side of the second side wall.
