Terminal module with improved shielding piece, manufacturing method thereof, and application thereof

A terminal module, comprising:

• a first terminal assembly, the first terminal assembly comprising:
• a plurality of first conductive terminals, the plurality of first conductive terminals comprising a first outer ground terminal, a second outer ground terminal, and at least one first signal terminal located between the first outer ground terminal and the second outer ground terminal;
• each first conductive terminal comprising a first conductive pad extending along a first direction;
• a first insulating block, the first insulating blocking being secured with the plurality of first conductive terminals;
• and
• a first shielding piece, the first shielding piece comprising a first shielding portion at least partially disposed in the first insulating block, a first side wall portion bent from one side of the first shielding portion, and a second side wall portion bent from another side of the first shielding portion;
• the first shielding portion corresponding to the first conductive pads;
• the first side wall portion being provided with at least one first abutting elastic arm;
• the at least one first abutting elastic arm being provided with at least one first abutting portion;
• the second side wall portion being provided with at least one second abutting elastic arm;
• the at least one second abutting elastic arm being provided with at least one second abutting portion;
• the first abutting portion being in contact with the first conductive pad of the first outer ground terminal;
• and the second abutting portion being in contact with the first conductive pad of the second outer ground terminal;
• and
• a second terminal assembly, the second terminal assembly comprising:
• a plurality of second conductive terminals, the plurality of second conductive terminals comprising a third outer ground terminal, a fourth outer ground terminal, and at least one second signal terminal located between the third outer ground terminal and the fourth outer ground terminal;
• each second conductive terminal comprising a second conductive pad extending along the first direction;
• a second insulating block, the second insulating blocking being secured with the plurality of second conductive terminals;
• and
• a second shielding piece, the second shielding piece comprising a second shielding portion at least partially disposed in the second insulating block, a third side wall portion bent from one side of the second shielding portion, and a fourth side wall portion bent from another side of the second shielding portion;
• the second shielding portion corresponding to the second conductive pads;
• the third side wall portion being provided with at least one third abutting elastic arm;
• the at least one third abutting elastic arm being provided with at least one third abutting portion;
• the fourth side wall portion being provided with at least one fourth abutting elastic arm;
• the at least one fourth abutting elastic arm being provided with at least one fourth abutting portion;
• the third abutting portion being in contact with the second conductive pad of the third outer ground terminal;
• and the fourth abutting portion being in contact with the second conductive pad of the fourth outer ground terminal;
• wherein the first shielding portion of the first shielding piece and the second shielding portion of the second shielding piece together form a first shielding layer located between the first conductive pads of the first conductive terminals and the second conductive pads of the second conductive terminals;
• and
• wherein the first shielding layer is free of any openings extending through the first shielding layer along a second direction perpendicular to the first direction, so as to reduce signal crosstalk between the first conductive pads of the first conductive terminals and the second conductive pads of the second conductive terminals.
