In other words, the first extension 1221 of the first torsion section 1222 is substantially perpendicular to the first coupling section 1223.

It should be noted that, in order to avoid the problem that the first torsion section 1222 is locally swollen due to the twist, the width of the plate surface 124 on the first torsion section 1222 is gradually reduced from the first extension section 1221 toward the first coupling section 1223. . Further, the width of the plate surface 124 on the first extension 1221 on the side of the first torsion section 1222 is greater than the width of the plate surface 124 on the first coupling section 1223 on the other side of the first torsion section 1222.

Furthermore, the second body portion 221 of the second body portion 221 is exposed outside the second insulative housing 21, and the width thereof is greater than the width of the portion of the second body portion 221 that is embedded in the second insulative housing 21 . (See Figure 5)

The twisting directions of any two adjacent second torsion segments 2222 of the sheet 2 are opposite to each other (eg, the plugging direction S is regarded as the central axis as a torsion reference, one is clockwise twisting, and the other is counterclockwise twisting ). In other words, the second extension 2221 plate surface 224 adjacent to the second torsion section 2222 and the second coupling section 2223 plate surface 224 are substantially perpendicular to each other.

It should be noted that in order to avoid the problem that the second torsion section 2222 is locally swollen due to the twist, the width of the plate surface 224 on the second torsion section 2222 is gradually reduced from the second extension section 2221 toward the second coupling section 2223. . Further, the width of the plate surface 224 on the second extension 2221 on the side of the second torsion section 2222 is greater than the width of the plate surface 224 on the second coupling section 2223 on the other side of the second torsion section 2222.

Referring to FIG. 6 , when the first signal chip 1 and the second signal chip 2 are adjacent to each other, the transmission module 10 is coupled to the first signal terminal 12 in a one-to-one correspondence.

For example, as shown in FIG. 7, the first signal chip 1 has only two first signal terminals 12 (such as the first and third first signal terminals 12 from the top in FIG. 7). A mating portion 122 and its corresponding second mating portion 222 form a narrow-side coupling structure, and the remaining two first signal terminals 12 (such as the second and fourth first signal terminals from the top to the bottom in FIG. 7) 12) The first mating portion 122 and the corresponding second mating portion 222 form a wide-side coupling structure.

For example, the width of the body portion 321 of each grounding terminal 32 can also be designed to be larger than the width of the corresponding first body portion 121 and the second body portion 221 . Better The width of the body portion 321 of each grounding terminal 32 is not more than twice the width of the corresponding first body portion 121, and each first body portion 121 is projected onto the corresponding body portion 321 thereof, first The contour of the body portion 121 is located within the contour of the body portion 321 to which it corresponds.
