As shown in fig. 6 and 8, since the rib 204 does not extend beyond the mating plate 202 in the mating direction, it is known that the rib 204 does not extend to the end of the mating plate 202 in the mating direction, and that the mating plate 202 is inserted into the electrical connector 100 earlier than the rib 204.

The electric connector and the connector combination have the following beneficial effects:

1) In the same terminal group R, the space between the ground terminal 2G and the signal terminal 2S adjacent to the ground terminal 2G is not provided with the barrier 16 separating the spring arms 22 of the two, and the space between the signal terminal 2S adjacent to the ground terminal 2G and the other signal terminal 2S is not provided with the barrier 16 separating the spring arms 22 of the two, so that in the terminal group R, air is provided around the contact portion 221 of the signal terminal 2S adjacent to the ground terminal 2G and the adjacent conductive terminal 2, the dielectric constant around the contact portion 221 of the signal terminal 2S is reduced, the capacity of the signal terminal 2S is further reduced, the impedance of the signal terminal 2S is improved, and the high-frequency performance of the signal terminal 2S is improved.

2) In the same terminal group R, the minimum distance D1 between the spring arms 22 of a pair of the signal terminals 2S is smaller than the minimum distance D2 between the spring arms 22 of the ground terminal 2G and the adjacent signal terminals 2S, so that the capacity of the signal terminals 2S in the terminal group R is further increased, the impedance of the signal terminals 2S is further improved, and the distance D1 between the spring arms 22 of a pair of the signal terminals 2S is shortened, so that a differential coupling design structure can be formed.

3) In either the terminal group R or the signal group Q, the spacer 17 is disposed between the tail portions 23 of the adjacent two conductive terminals 2 to space the adjacent two conductive terminals 2 apart from each other to avoid short-circuiting, whereas in either the terminal group R or the signal group Q, at least one of the conductive terminals 2 adjacent to the spacer 17 is the signal terminal 2S, the spacer 17 does not extend between the two spring arms 22 of the adjacent two conductive terminals 2 to avoid the spacer 17 affecting the dielectric constant of the surrounding environment of the contact portion 221 of the signal terminal 2S, thereby affecting the impedance of the signal terminal 2S and the high-frequency performance of the signal terminal 2S.

4) The first side wall 12 is provided with one barrier 16 between the signal group Q and two adjacent terminal groups R, so as to avoid signal interference of the signal terminals 2S in the signal group Q by the signal terminals 2S in the two terminal groups R.

5) In the transverse direction, the thickness T1 of the first side wall 12 at the recess 122 is smaller than the minimum distance D3 between the surface of the second side wall 13 facing the slot 11 and the surface of the second side plate 32 facing away from the slot 11, and the distance D4 between the rib 204 and the board 201 is smaller than the minimum distance D3 between the surface of the second side wall 13 facing the slot 11 and the surface of the second side plate 32 facing away from the slot 11, so that when the mating connector 200 is reversely inserted into the electrical connector 100, the rib 204 which should be inserted into the recess 122 is impacted by the second side wall 13 and the second side plate 32, thereby preventing the mating connector 200 from being reversely inserted.

6) In the lateral direction, the minimum distance D3 between the surface of the second side wall 13 facing the slot 11 and the surface of the second side plate 32 facing away from the slot 11 is at least twice the thickness T1 of the first side wall 12 at the recess 122, the minimum distance D3 between the surface of the second side wall 13 facing the slot 11 and the surface of the second side plate 32 facing away from the slot 11 is at least 1.5 times the distance D4 between the rib 204 and the board 201, so that the rib 204 is significantly impacted by the second side wall 13 and the second side plate 32 when the mating connector 200 is inserted back into the electrical connector 100, and it is not practical for a user to insert the mating connector 200 rigidly into the electrical connector 100.

7) The recess 122 does not extend beyond the bottom plate 314 along the abutting direction, so that the recess 122 does not extend too far along the abutting direction to cause excessive strength degradation of the first side wall 12, and the abutting plate 202 located between the first side plate 31 and the first side wall 12 cannot be well clamped.

8) In order to ensure the holding force with the latch plate 311, the abutment plate 202 protrudes toward the plug plate 201 to form the boss 203, the boss 203 extends to two ends of the abutment plate 202 along the longitudinal direction, and the sum of the thicknesses T2 of the abutment plate 202 and the boss 203 is greater than the thickness T3 of the guide plate 205.

9) In order to accommodate the boss 203 and avoid increasing the height of the electrical connector 100 in the lateral direction, the side of the first side wall 12 facing the mating groove 4 is recessed toward the slot 11 in the lateral direction to form the recess 121.

10 In the lateral direction), the distance D5 between the abutment plate 202 and the first side wall 12 is greater than the distance D6 between the boss 203 and the first side wall 12 at the position corresponding to the boss 203, and greater than the distance D7 between the rib 204 and the first side wall 12 at the position corresponding to the rib 204, so that a hard interference is not formed between the abutment plate 202 and the first side wall 12 when contacting the first side wall 12, avoiding damaging the connector assembly.

The above detailed description is merely illustrative of the preferred embodiments of the utility model and is not intended to limit the scope of the utility model, so that all equivalent technical changes that can be made by the present specification and illustrations are included in the scope of the utility model.
