In this embodiment, please refer to fig. 4 and 5, the terminal block 22 is assembled by a first block 22A and a second block 22B, the signal terminals 23 and the ground terminals 24 can be respectively disposed on the first block 22A and the second block 22B, and two adjacent signal terminals 23 can be arranged between the two ground terminals 24 according to the actual requirement of the connector 2, but not limited thereto. An assembly space 220 can be formed between the first base 22A and the second base 22B, so that the conductive ground element 26 can be accommodated in the assembly space 220. In addition to the aforementioned terminal seat 21, in other embodiments of the present invention, a person skilled in the art can make the terminal seat 22 be a single component or composed of more than three components according to production or design requirements, and even make the terminal seat 22 and the insulating body 21 integrally formed to shorten the production process, that is, as long as the connection relationship between the insulating body 21 and the signal terminal 23, the grounding terminal 24, and the conductive grounding member 26 is consistent with the description of the embodiments of the present invention, the "connection position" between the insulating body 21 and the aforementioned components belongs to the terminal seat 22 of the present invention.

In addition, as shown in fig. 4 and fig. 5, in this embodiment, the first base 22A is provided with at least one first assembling portion 221, the second base 22B is provided with at least one second assembling portion 222, the conductive ground element 26 is provided with at least one third assembling portion 261, the third assembling portion 261 can be assembled with the corresponding first assembling portion 221 and/or second assembling portion 222, respectively, so that the first base 22A, the second base 22B and the conductive ground element 26 are integrated into a whole, in this embodiment, the first assembling portion 221 and the second assembling portion 222 are convex columns, the third assembling portion 261 is an opening, and the convex columns of the first base 22A and the second base 22B can simultaneously extend into the same opening, or a single convex column is forced to match with a single opening, and the assembling manner can be fastening, clamping, fusion, bonding, and the like.

It is particularly mentioned that the conductive grounding member 26 can be made of metal or conductive plastic, and besides being a separate component to be assembled to the terminal base 22, it can also be fixed on the terminal base 22 by injection molding (when it is made of conductive plastic), for example, the conductive grounding member 26 can be formed on the first base 22A first by injection molding, and then, the portion of the conductive grounding member 26 that exceeds the first base 22A can be assembled into the second base 22B completely or partially; alternatively, the conductive grounding member 26 can be formed on the first seat 22A and the second seat 22B by injection molding, and then the first seat 22A and the second seat 22B are combined together, so that the conductive grounding members 26 in the first seat 22A and the second seat 22B can be connected to each other to form a whole.

As shown in fig. 4 and fig. 5, a plurality of abutting columns 263 are protruded from the front side of the conductive grounding member 26, each abutting column 263 corresponds to each grounding terminal 24, and one side of the connecting portion facing the corresponding ground terminal 24 extends to form at least one abutting portion 265, each abutting portion 265 is located higher than the front side of the terminal seat 22 (the first seat 22A or the second seat 22B) and abuts against the corresponding ground terminal 24 (as shown in fig. 6 and 7), since the ground terminal 24 exceeds the area of the terminal block 22 (the first seat 22A or the second seat 22B), without being limited by the terminal block 22, and has a large deformation amount (elasticity), therefore, when the abutting portion 265 is long due to a tolerance problem, it can push the corresponding ground terminal 24 to deform, so that the conductive ground member 26 can still be smoothly assembled to the terminal base 22.

As shown in fig. 6 and 7, when the connector 2 is plugged into another connector 3, the metal terminal 31 of the another connector 3 is electrically connected to the grounding terminal 24, and at the same time, a force (shown by a dotted arrow in fig. 7) is applied to the grounding terminal 24 to displace the grounding terminal 24 toward the abutting portion 265, so that the grounding terminal 24 and the abutting column 263 can be more closely abutted, and when the abutting portion 265 is shorter due to tolerance, the grounding terminal 24 can be forced to abut against the corresponding abutting portion 265 by the abutting result of the metal terminal 31 of the another connector 3, so as to exert the function of the conductive grounding member 26. Thus, the structure of the conductive grounding member 26 of the present invention can effectively improve the yield of production, and reduce the problem of the conductive grounding member 26 derived from the tolerance, after all, the range of the aforementioned tolerance is not too large, and those skilled in the art can mix the elastic material in the conductive plastic to manufacture the conductive grounding member 26, for example, mix rubber and carbon black plastic with conductive property, conductive foam, etc., so that the conductive grounding member 26 has a large deformation capability, the length of the abutting portion 265 can be increased to ensure that the grounding terminal 24 and the conductive grounding member 26 can form electrical connection; when the connectors 2 and 3 are plugged, the metal terminal 31 of the other connector 3 can force the ground terminal 24 and the abutting cylinder 263 to deform, and at the same time, the grounding terminal 24 and the metal terminal 31 can be more tightly attached to each other due to the acting force applied to the grounding terminal 24 by the abutting cylinder 263 relative to the acting force applied by the metal terminal 31.

It is particularly mentioned that, in other embodiments of the present invention, a person skilled in the art can adjust the structure of the conductive grounding member 26 according to the actual state of the terminal base 22, therefore, the style of the conductive grounding member 26 is not limited to the content shown in fig. 4, and the protection scope of the present invention is to be covered as long as the abutting portion 265 is higher than the front side of the terminal base 22 to abut against the higher region of the grounding terminal 24. The above description is only a preferred embodiment of the present invention, and the claimed scope of the present invention is not limited thereto, and those skilled in the art can easily understand the equivalent changes according to the technical content disclosed in the present invention, and all should belong to the protection scope of the present invention.
