Next, as shown in fig. 1 and 2, a first connecting portion 111 (e.g., a pivot structure) is disposed at one end (e.g., front end) of the metal cover 11, and a first connecting portion 112 (e.g., a hook structure) is disposed at the other end (e.g., rear end) of the metal cover 11; the insulating base 12 has a second connecting portion 121 (e.g., a pivot hole) at one end (e.g., front end), and a second connecting portion 122 (e.g., a slot) at the other end (e.g., rear end), wherein the first connecting portion 111 and the second connecting portion 121 can be pivoted (e.g., pivot shaft, pivot hole), the first connecting portion 112 and the second connecting portion 122 can be fastened (e.g., fastened by a hook, a slot, or two mutually engageable protrusions, etc.), and the first connecting portion 112 and the second connecting portion 122 can be coupled in a matching manner, so that the metal cover 11 can be coupled (e.g., pivoted) to the second connecting portion 121 of the insulating base 12 by the first connecting portion 111, so that the metal cover 11 can rotate about the aforementioned position as an axis, so as to be able to rotate in a direction approaching or separating from the insulating base 12. After the metal cover 11 rotates toward the insulating base 12, the metal cover 11 and the insulating base 12 are stably combined into the connector body 1 until the first connecting portion 112 is fixed to the second connecting portion 122 of the insulating base 12 (as shown in fig. 3B). In other embodiments of the present disclosure, the connector body 1 may be assembled by using more than three components according to the production or use requirements.

With continued reference to fig. 1 to 2, each shielding fixing piece 2 can be fixed in each corresponding accommodating space 10, and at least one abutting portion 21 is protruding from one side thereof. In the first embodiment, the abutting portion 21 is integrally formed on the shielding fixing piece 2, for example, but not limited to, the abutting portion 21 is punched out of the shielding fixing piece 2 having a plate shape by a punching technique. In other embodiments of the present disclosure, the abutment portion 21 can be a separate component and fixed to the shielding fixing piece 2, or can be made on the shielding fixing piece 2 by other forming means, as long as the abutment portion 21 can form an electrical connection with the shielding fixing piece 2. In addition, as shown in fig. 4, at least one inserting slot 13 is disposed in the connector body 1 (e.g. the insulating base 12), so that the shielding fixing piece 2 can extend into and be positioned in the inserting slot 13. In other embodiments of the present disclosure, the shield fixing piece 2 can be fixed into the connector body 1 in other ways.

In addition, as shown in fig. 1 to 4, at least one end of the shielding fixing piece 2 can be provided with a positioning piece 22, and the positioning piece 22 can be attached to a bearing portion 123 of the insulating base 12, and after the metal cover 11 and the insulating base 12 are assembled into a whole (as shown in fig. 3B), the positioning piece 22 can be clamped between the metal cover 11 and the bearing portion 123 (or the insulating base 12) (as shown in fig. 4), so that the metal cover 11 and the shielding fixing piece 2 can be electrically connected. Meanwhile, in the use process of the connector C, when the terminal set 3 is plugged and unplugged, the positioning piece 22 can enable the shielding fixing piece 2 to be stably positioned into the connector body 1 through the clamping action of the metal cover 11 and the insulating base 12, and cannot be easily separated from the current assembly position.

Furthermore, as shown in fig. 1 and 2, each of the terminal sets 3 can be fixed to the corresponding accommodating space 10, wherein each of the terminal sets 3 includes a plurality of signal terminals 31 and a plurality of ground terminals 32, and as shown in fig. 5, one end of each of the signal terminals 31 can be used to contact a signal terminal of another connector or contact a signal conductive contact (Gold Finger) on a circuit board, so as to be capable of transmitting or receiving signals; the other ends of the signal terminals 31 can be fixed to core wires E1 of a transmission line E, respectively. One end of the ground terminal 32 can be used to contact a ground terminal of another connector, or to contact a ground conductive contact (Gold Finger) on a circuit board for grounding purposes; the other ends of the grounding terminals 32 can be connected integrally with each other, but are not limited thereto. In other embodiments of the present disclosure, the other end of each of the ground terminals 32 can also be separated from each other.

With continued reference to fig. 1 and 5, the terminal set 3 may further include a conductive plastic member 33, where the conductive plastic member 33 includes a plurality of contact portions 331, and each of the contact portions 331 is capable of contacting and wrapping each of the ground terminals 32, that is, the contact portion 331 is capable of extending beyond two corresponding sides of the ground terminal 32 (as shown in fig. 6 and 7). When the terminal set 3 is assembled to the connector body 1, the terminal set 3 further includes an insulating member 34, and the insulating member 34 can cover at least part of the conductive plastic member 33, at least part of the signal terminals 31 and at least part of the ground terminals 32 so that the terminal set 3 can form a whole. In the first embodiment, the insulating member 34 can be fixed on the signal terminals 31 and the ground terminals 32 by injection molding, and a filling space 340 can be formed on the insulating member, and the filling space 340 only exposes a portion of the ground terminals 32 but not the signal terminals 31, then, the liquid conductive plastic member 33 is injected into the filling space 340 by injection molding, and the conductive plastic member 33 (including the contact portion 331) is formed after the insulating member is cooled. In other embodiments of the present disclosure, the conductive plastic member 33 and the insulating member 34 can be snapped, assembled or otherwise secured to the signal terminal 31 and the ground terminal 32, or only the conductive plastic member 33 or the insulating member 34 can be provided, as stated herein.

Next, as shown in fig. 1 to 7, after the terminal set 3 is assembled to the connector body 1, the contact portion 331 of the conductive plastic member 33 can contact the contact portion 21 of the shielding fixing piece 2, so that the ground terminal 32 and the contact portion 21 are indirectly electrically connected (i.e. indirectly contacted), but not limited thereto. In other embodiments of the present disclosure, the grounding terminal 32 can directly contact the corresponding abutment portion 21, for example, the grounding terminal 32 and/or the abutment portion 21 are respectively provided with a bending section, so as to achieve the effect of mutual contact through the bending sections. That is, at least one grounding terminal 32 of the present disclosure can directly or indirectly contact the abutting portion 21 of the shielding fixing piece 2 located in the same accommodating space 10, so that the connector C can form a first grounding path for grounding, namely, the metal cover 11, the shielding fixing piece 2, the conductive plastic member 33 and the grounding terminal 32. In addition, when the connector C has a plurality of terminal groups 3, one shielding fixing piece 2 can be stored between any two adjacent terminal groups 3, so that the two adjacent terminal groups 3 are not easy to interfere with each other.

In addition, as shown in fig. 1 to 2, the housing 4 can be made of metal material, a housing space 40 is provided therein, and the connector body 1 can be accommodated in the housing space 40, so as to achieve the effects of preventing electromagnetic interference (EMI), acting as a grounding path, protecting the connector body 1, and the like through the effect of the housing 4. The metal cover 11 is provided with at least one cover positioning portion 114 (e.g., a bump), the housing 4 is provided with at least one housing positioning portion 41 (e.g., an opening), and the cover positioning portion 114 and the housing positioning portion 41 are matched and can be combined and assembled with each other. In this embodiment, the cover positioning portion 114 is configured as a bump, and the housing positioning portion 41 is configured as an opening, but not limited thereto. In other embodiments of the present disclosure, the configurations of the cover positioning portion 114 and the housing positioning portion 41 are also interchangeable. When the connector body 1 is assembled to the housing 4, the cover positioning portion 114 is combined with the corresponding housing positioning portion 41, for example, the protruding block can be inserted into the hole to fix the connector body 1 into the hole, so that the connector body 1 cannot be easily separated from the housing 4, and thus, the connector C can form a second grounding path for grounding, namely, the housing 4, the metal cover 11 and the shielding fixing piece 2. Therefore, through the overall structure of the present disclosure, the first grounding path and/or the second grounding path can be respectively communicated with the grounding circuit of the circuit board or other grounding components, so as to form a good grounding path, so that a good shielding effect is achieved among the terminal groups 3, interference of adjacent terminal groups 3 when the terminal groups 3 transmit high-frequency signals is reduced, and the connector C has more stable performance when high-frequency and high-speed transmission is performed.

Furthermore, the connector C of the present disclosure can be changed in accordance with the product requirements in addition to the structural form of the foregoing first embodiment, and only the components having the structure different from that of the first embodiment will be described. In the second embodiment of the present disclosure, as shown in fig. 8 to 10, one end of the metal cover 51 (as the rear end of the metal cover 51 in the upper left direction of fig. 8) is provided with a first connecting portion 511, and the other end of the metal cover 51 (as the front end of the metal cover 51 in the lower right direction of fig. 8) is provided with a first connecting portion 512; one end of the insulating base 52 (as the rear end of the insulating base 52 in the upper left direction of fig. 8) is provided with a second coupling portion 523, and the other end of the insulating base 52 (as the front end of the insulating base 12 in the lower right direction of fig. 8) is provided with a second connecting portion 524.

Thus, after the first combining portion 511 and the second combining portion 523 are combined (e.g. pivoted), a worker or a machine can easily press the pressing platform 513, so that the first connecting portion 512 is fixed to the second connecting portion 524 to form the connector body 5, and then the connector body 5 is assembled into the housing 8.

In addition, in order to make the assembly and combination of the shielding fixing piece and the terminal set more stable, in the second embodiment, referring to fig. 8 and 11, the insulating member 64 of the terminal set 6 is provided with at least one first inserting and clamping portion 641 (e.g. an opening), the shielding fixing piece 7 is provided with at least one second inserting and clamping portion 73 (e.g. a tab), each first inserting and clamping portion 641 can be matched and clamped with the corresponding second inserting and clamping portion 73, in addition, an abutting piece 74 is further provided at the other end position of the shielding fixing piece 7 away from the positioning piece 72 provided at one end thereof, and the abutting piece 74 can abut against the insulating member 64 (as shown in fig. 10) so as to enhance the combination stability of the terminal set 6 and the shielding fixing piece 7.
