Only the second terminal module 2b is mounted on the second side wall 12, and the second terminal module 2b includes the terminal 21 and the insulating block 29 for fixing the terminal 21.

Taking the first terminal module 2a as an example, the terminals 20 are arranged in a row and include a plurality of ground terminals 20G and a plurality of signal terminals 20S, and each terminal 20 includes a contact portion 201 extending into the mating slot 101, a fixing portion 202 fixed to the insulating block 29, and a pin 203 extending out of the bottom surface of the insulating body 10. The second fixing portion 202S corresponding to the signal terminal 20S is completely wrapped in the insulating block, and the first fixing portion 202G corresponding to the ground terminal 20G is partially exposed from the insulating block. Referring to fig. 5 to 8, the first terminal module 2a is inserted from the bottom surface of the insulating body 1 and the terminals 20 are arranged on the corresponding first sidewall 11, the insulating block 29 is provided with a groove 290 partially exposing the corresponding first fixing portion 202G, and the groove 290 is a vertical groove and penetrates through the upper and lower surfaces of the insulating block 29. The grounding member 3 is further provided with an abutting portion 31 which passes through the groove 290 and abuts against the first fixing portion 202G, so as to realize the electrical connection of each row of grounding terminals and form a grounding loop. The side walls 11, 12 of the insulating body 1 are provided with recesses 13 at positions corresponding to the insulating blocks 29, and the insulating blocks 29 are fixed in the recesses 13 and constitute a part of the side walls. The sidewall 11 is provided with a downward penetrating slit 102 at a position corresponding to the groove 290, and the abutting part 311 provided on the grounding member 3 and extending vertically upward passes through the groove 290 and the slit 102 and abuts against the first fixing part 202G; the grounding member 3 has a downward vertically extending abutting portion 312, which passes through the groove 290 and abuts against the first fixing portion 202G. The abutting portion 31 is in the form of a vertical plate and is connected to the first fixing portion 202G by spot welding, and the ground member 3 is connected to the first fixing portion 202G by welding through the upper and lower

abutting portions

311 and 312 to fix the ground member, as shown in fig. 7 and 8.
