In the present embodiment, the shape of the first groove 141 corresponds to the first metal serial connector 5, the shape of the second groove 122 corresponds to the second metal serial connector 6, and the inner sidewall of the first groove 141 is preferably formed with a plurality of protrusions 142 (e.g., fig. 10), but the invention is not limited thereto.

The signal terminals 2 and the ground terminals 3 can be regarded as rear terminals in this embodiment and are mounted in the insulating housing 1 (e.g., the rear terminal mounting groove 121), and the signal terminals 2 and the ground terminals 3 are arranged along the length direction L and are staggered; for example: two signal terminals 2 are disposed between two adjacent ground terminals 3, which may be a differential signal pair, but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, only one signal terminal 2 may be disposed between two adjacent ground terminals 3. Furthermore, a part of any one of the signal terminals 2 and a part of any one of the ground terminals 3 are located in the accommodating groove 111 and are configured to abut against the mating component inserted in the accommodating groove 111.

However, since the structure of the plurality of ground terminals 3 is substantially the same as that of the present embodiment, the structure of one of the ground terminals 3 will be described below for convenience of description, but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the structure of the plurality of ground terminals 3 may be slightly different.

Specifically, as shown in fig. 4 to 6, each of the ground terminals 3 includes a ground spring arm section 31, a ground welding section 32, and a ground mounting section 33 connected between the ground spring arm section 31 and the ground welding section 32; that is, the grounding spring arm section 31 and the grounding welding section 32 are respectively formed by integrally extending two ends of the grounding installation section 33 in a direction away from each other.

The grounding elastic arm section 31 extends from the grounding installation section 33 toward the front side surface 11 to be located in the accommodating groove 111; the ground welding section 32 extends from the ground mounting section 33 toward the bottom surface 14 and then extends out of the rear terminal mounting groove 121 (or the bottom surface) to form a structure suitable for Surface Mounting Technology (SMT), but the invention is not limited thereto.

The second protrusion 334 extends from an edge of the extension 331 adjacent to the second groove 122 (e.g., a left middle edge of the extension 331 in fig. 5) toward the second groove 122, so that at least a part of the second protrusion 334 is located in the second groove 122, that is, the second protrusion 334 extends from a side or edge of the extension 331 adjacent to the front side 11 and approximately at the middle or middle of the side or edge toward the front side 11 and the second groove 122 along a second direction D2. The extending directions of the first protrusion 333 and the second protrusion 334 are the same direction or opposite directions.

It should be noted that, the structure of any one of the signal terminals 2 is substantially the same as that of the ground terminal 3, but any one of the signal terminals 2 does not have the first protruding portion 333 and the second protruding portion 334 of the ground terminal 3, and the portion of any one of the signal terminals 2 corresponding to the ground spring arm section 31 has a shorter length, that is, the end portion of the ground spring arm section 31 of the ground terminal 3 adjacent to the front side surface 11 is closer to the front side surface 11 than the portion of the signal terminal 2 corresponding to the end portion of the ground terminal 3.

In addition, the positioning buckle 7 is inserted and fixed to the insulating housing 1 from the rear side 12 toward the front side 11 along the second direction D2, and a part of the positioning buckle 7 is inserted into the notches 3322 of the plurality of ground terminals 3 (and corresponding portions of the plurality of signal terminals 2), that is, the positioning buckle 7 is inserted from a portion of the rear terminal corresponding to an opening of the notch 3322 of the ground terminal 3 so as to fix the rear terminal (that is, the plurality of ground terminals 3 and the plurality of signal terminals 2) to the insulating housing 1 or to the rear terminal mounting groove 121.

The insertion section 43 and the welding section 44 are formed by extending from the other end of the main body section 41 adjacent to the bottom surface 14 (e.g., the bottom end of the main body section 41 in fig. 5), and the insertion section 43 is inserted and fixed to the insulating housing 1 along the second direction D2 toward the rear side 12, while the welding section 44 passes through the bottom surface 14 to form a structure suitable for Surface Mounting Technology (SMT), but the invention is not limited thereto. For example, in other embodiments not shown in the present disclosure, the welding section 44 may be a structure (e.g., a fish-eye foot) suitable for inserting welding.

Further, in any one of the conductive terminals 4 and the corresponding ground terminal 3, the spring arm segment 42 and the ground spring arm segment 31 extend toward each other along the second direction D2 and are disposed at an interval and correspond to each other in the first direction D1, that is, the orthographic projection of the spring arm segment 42 and the ground spring arm segment 31 in the first direction D1 partially overlaps, and the bottom edge of the soldering segment 44 is coplanar with the bottom edge of the ground soldering segment 32. In addition, the corresponding relationship between the position of any one of the conductive terminals 4 and the corresponding signal terminal 2 is substantially the same as the corresponding relationship between the position of the conductive terminal 4 and the corresponding ground terminal 3, which is not described herein again.
