[0044] Please refer to Figures 9 to 12 As shown, the present invention discloses a second electrical connector 200, which has the same structure as the first connector 100 for most of the time, and the main difference between the two is that: in the first connector 100, the plurality of pairs of first signal terminals S1 and the plurality of pairs of second signal terminals S2 are all non-cross structures, that is, there is no overlapping portion between each pair of first signal terminals S1 in the direction perpendicular to the first and second side surfaces 101, 102 of the first insulating portion 10 (i.e., the thickness direction of the first insulating portion 10), and there is no overlapping portion between each pair of second signal terminals S2 in the direction perpendicular to the third and fourth side surfaces 201, 202 of the second insulating portion 20 (i.e., the thickness direction of the second insulating portion 20), and each pair of first signal terminals S1 and each pair of second signal terminals S2 of the first connector 100 are in the shape of straight strips; while in the second electrical connector 200, the plurality of pairs of first signal terminals S1 include at least one pair of mutually crossed first signal terminals S1, and the plurality of pairs of second signal terminals S2 include at least one pair of mutually crossed second signal terminals S2. The at least one pair of mutually crossed first signal terminals S1 together form a first cross structure X1, and the at least one pair of mutually crossed second signal terminals S2 together form a second cross structure X2. In this embodiment, in the second electrical connector 200, the plurality of pairs of first signal terminals S1 include a plurality of pairs of mutually crossed first signal terminals S1, and a pair of mutually non-crossed first signal terminals S1 is provided between two adjacent pairs of mutually crossed first signal terminals S1; the plurality of pairs of second signal terminals S2 include a plurality of mutually crossed second signal terminals S2, and a pair of mutually non-crossed second signal terminals S2 is provided between two adjacent pairs of mutually crossed second signal terminals S2.

[0045] Please refer to Fig. 9As shown, in the second electrical connector 200, the first insulating portion 10 is provided with at least one second groove 104 located on the first side surface 101, and the first cross structure X1 is exposed in the second groove 104, so that the first cross structure X1 is exposed to the air; see Fig.10 As shown, the second insulating part 20 is provided with at least one fourth groove 204 located on the third side 201, and the second cross structure X2 is exposed in the fourth groove 204, so that the second cross structure X2 is exposed to the air. In the illustrated embodiment of the present invention, the first cross structure X1 overlaps but does not touch in the direction perpendicular to the first and second side surfaces 101, 102 of the first insulating part 10 (i.e., the thickness direction of the first insulating part 10); the second cross structure X2 overlaps but does not touch in the direction perpendicular to the third and fourth side surfaces 201, 202 of the second insulating part 20 (i.e., the thickness direction of the second insulating part 20).

[0051] The above embodiments are only used to illustrate the present invention but not to limit the technical solutions described in the present invention. The understanding of this specification should be based on the technicians in the relevant technical field. For example, for the directional description of "up" and "down", although this specification has described the present invention in detail with reference to the above embodiments, ordinary technicians in the field should understand that technicians in the relevant technical field can still modify or replace the present invention with equivalents, and all technical solutions and improvements that do not depart from the spirit and scope of the present invention should be covered within the scope of the claims of the present invention.
