2) The bending part 222 extends forwards from the first embedded part 221, the plastic block 21 is located in the abdicating groove 2111, so that the bending jig can be fixed by using the first embedded part 221 as a fixing point to better apply a stamping force to form the bending part 222, and the abdicating groove 2111 can abdicate the bending jig.

3) The receiving slot 16 is formed by being recessed forward from the rear end surface of the insulating body 1, the first insertion slots 12 are disposed in front of the receiving slot 16 at intervals, the receiving slot 16 is communicated with the first insertion slots 12, so that after the terminal assembly 2 is inserted forward into the insulating body 1, the plastic block 21 is received in the receiving slot 16, the first connecting portions 223 are received in the first insertion slots 12 one by one, the receding slot 2111 is located behind the first insertion slots 12, and the bending portion 222 is located in the receding slot 2111, it can be known that the bending portion 222 is also located behind the first insertion slots 12, and the bending portions 222 do not need to enter the first insertion slots 12 one by one, so that the bending portions 222 do not collide with the barrier between two adjacent first insertion slots 12, a bending angle of the bent portion 222 is secured, and thus a required height of the first contact portion 224 is secured.

4) The first contact portion 224, the second contact portion 233 and the third contact portion 243 are formed by bending and extending downward, and it is understood that the first contact portion 224, the second contact portion 233 and the third contact portion 243 formed by bending and extending in the same direction can be formed by pressing only in a single pressing direction.

5) Since the first connecting portion 226, the second connecting portion 235 and the third connecting portion 245 are all flush in the left-right direction, the first connecting portion 226, the second connecting portion 235 and the third connecting portion 245 can be connected by the first tape R1, so that the first terminal 22, the second terminal 23 and the third terminal 24 can be formed into the first buried portion 221, the second buried portion 231 and the third buried portion 241 at the same level by the first tape R1. Since the first buried portion 221, the second buried portion 231, and the third buried portion 241 are located at the same horizontal plane, it is convenient to embed the first buried portion 221, the second buried portion 231, and the third buried portion 241 in the same plastic block 21, and assemble the first terminal 22, the second terminal 23, and the third terminal 24 to the insulating body 1 through the first tape R1.

6) Compared with the first terminal 22, the second terminal 23 and the third terminal 24 which are located at different heights and are located at the upper side of the slot 11 together, the fourth terminals 3 can be directly fixed with the terminal receiving slots 15 only by the fixing portions 31, so that the fourth group of terminals 3 can be integrally assembled on the insulating body 1, and the operation is simple.

7) The first welding portion 225 and the second welding portion 234 are both formed by directly extending backwards and horizontally from the second portion P2 embedded in the vertical block 212, and it can be known that the second portion P2 fixed in the vertical block 212 is a fixed point, which is more convenient for a jig to form the first welding portion 225 and the second welding portion 234 extending horizontally and located on the same plane, thereby better ensuring the coplanarity required by the first welding portion 225 and the second welding portion 234.

8) The grounding piece 25 can not only shield the first portion P1 of the first window W1 from the signal terminal S through the shielding portion 252 thereon to improve the impedance of the signal terminal S and reduce the loss of the signal terminal S, but also enter the second window W2 through the contact arm 253 thereon to contact the grounding terminal G to achieve the common grounding of the grounding piece 25 and the grounding terminal G, and further fix the terminal assembly 2 to the insulating body 1 through the latching engagement between the latching portion 254 and the insulating body 1, thereby achieving three functions of the grounding piece 25.

9) The width of the first windows W1 in the left-right direction is greater than the width of the second windows W2 in the left-right direction, and it can be seen that the first windows W1 and the second windows W2 are arranged at intervals in the left-right direction, but not communicated with each other, which can ensure that a pair of differential signal terminals are fully exposed, and can also avoid that the strength of the plastic block 21 is reduced because the first windows W1 and the second windows W2 are communicated with each other.

10) Since one shielding portion 252 is used for shielding the first portion P1 of the pair of differential signal terminals exposed at the first window W1, and the contact arm 253 is used for contacting only one ground terminal G, it can be seen that the shielding portion 252 has a larger area than the contact arm 253, and the shielding portion 252 can be torn more easily to form the latch 254, which has a larger tearing space compared to the contact arm 253.

11) The first window W1 penetrates through the plastic block 21 in the vertical direction, so that the whole peripheral outer surface of the first part P1 of the signal terminal S is exposed at the first window W1, the air filled in the first window W1 is utilized to reduce the dielectric constant around the signal terminal S, the second window W2 is formed in a downward concave manner in the vertical direction and is rectangular, and based on the fact that the ground terminal G extends in the front-back direction, the length of the second window W2 in the front-back direction is greater than the width of the second window W2 in the left-right direction, the contact arm 253 can be effectively ensured to be in contact with the ground terminal G in a larger area, and further the contact between the contact arm 253 and the ground terminal G is ensured to be effectively in contact.
