Referring to FIG. 1 and FIG. 2 simultaneously, in the embodiment, the plug electrical connector 100 includes an insulator 110, a plurality of elastic terminals, a housing 140, a grounding fastener 160, and at least one grounding piece. Here, taking the USB Type C plug electrical connector as an example, the elastic terminal includes a first terminal set 120A and a second terminal set 120B, and the at least one grounding piece includes the grounding pieces 130A and 130B.

In the present embodiment, the first terminal group 120A and the second terminal group 120B are arranged in parallel with each other in the insulator 110, wherein the first terminal group 120A has a pair of ground terminals G1, G2, and the second terminal group 120B There is a pair of grounding terminals G3, G4. It can be clearly seen from FIG. 2 that the elastic terminals of the first terminal group 120A and the elastic terminals of the second terminal group 120B are respectively arranged along the axial direction L1 and at the first terminal. In the group 120A, the ground terminals G1, G2 are arranged in the outermost portion of the remaining elastic terminals in the axial direction L1, and in the second terminal group 120B, the ground terminals G3, G4 are arranged in the axial direction L1 in the rest. The outermost side of the elastic terminal. That is, among the elastic terminals arranged in the axial direction L1, the ground terminals G1 to G4 are arranged in the first position or/and the last position, respectively. Here, the axial direction L1 is orthogonal to the other axial direction L2, and the axial direction L2 is regarded as the insertion axial direction of the plug electrical connector 100.

Further, the insulator 110 of the present embodiment includes a first member 112 and a second member 114, and each of the elastic terminals has a holding portion S1 and an elastic portion S2, wherein the holding portion S1 is fixed to the first member 112. The second member 114 has a plurality of slots 114c and a plurality of ribs 114d spaced apart from each other along the axial direction L1. The elastic terminals extend from the first member 112 toward the second member 114 and are suspended, and the elastic segments S2 thereof respectively correspond to Ground is exposed from these slots 114c. In other words, the rib 114d is located between the adjacent two slots 114c to space apart the adjacent two slots from the adjacent two resilient terminals. The grounding fastener 160 is embedded in the first component 112 and extends toward the second component 114. The grounding fastener 160 is located on opposite sides of the elastic terminal in the axial direction L1 and partially recessed into the opposite sides of the second component 114. 114a. When the plug electrical connector 100 and the receptacle electrical connector 200 (shown in the following figures) are docked in the axial direction L2, the grounding fastener 160 is used to fasten to the receptacle electrical connector 200.

In the present embodiment, the plug electrical connector 100 includes a pair of grounding strips 130A, 130B and a pair of insulating sheets (Mylar) 150A, 150B. The grounding strips 130A, 130B are disposed above and below the insulator 110, and the insulating sheets are disposed. 150A and 150B are also disposed on the grounding strips 130A and 130B in the upper and lower directions, and are located on the side away from the insulator 110. In detail, the grounding strips 130A, 130B each have a latching portion 132, a tongue portion 134 and abutting portion 136, wherein the latching portion 132 is for holding the second component 114 of the insulator 110, and the tongue portion 134 will pass over the insulating sheet 150A. 150B is abutted against the inner surface of the outer casing 140 to provide an EMI shielding effect together with the grounding strips 130A, 130B. The abutting portion 136 passes through the opening 114b of the second member 114. When the plug electrical connector 100 is mated with the receptacle electrical connector 200, the abutting portion 136 abuts against the receptacle electrical connector 200 to provide a clamping effect. The outer casing 140 is configured to house the insulator 110, the first terminal group 120A, the second terminal group 120B, the grounding pieces 130A, 130B, the insulating sheets 150A, 150B, and the grounding fastener 160.

3 is a partial schematic view of the plug electrical connector. Here, in the bottom view of FIG. 2, please refer to FIG. 3 and refer to FIG. 2. Since the grounding plates 130A, 130B are respectively disposed on the upper and lower surfaces of the insulator 110 and are symmetrical, a grounding piece will be subsequently used. For the description, the other surface of the second member 114 and the grounding piece also have the same structure and will not be described again.

In the present embodiment, the grounding lug 130A, 130B also has an opening 138 that is substantially at the top plane P1 (or a plane parallel thereto when the ground lug 130A, 130B is assembled to the top plane P1 of the second component 114) At this time, the opening 138 will surround the rib 114d of the second member 114, and more importantly, for the slot 114c located at the most lateral edge, the opening 138 will only partially expose the position at the most edge. The slot 114c is the leftmost and rightmost slot 114c as shown in FIG. In other words, the elastic terminals of the present embodiment, particularly the ground terminals G1 to G4), will thus have a specific corresponding positional relationship with the grounding strips 130A, 130B as described below.

In fact, for the first terminal group 120A and the second terminal group 120B, since the ground terminals G1 to G4 are disposed at the outermost sides of the remaining elastic terminals, the openings 138 of the grounding pieces 130A, 130B are also only partially exposed to the outermost side. The slot 114c, as exemplified in FIG. 3, will cause the orthographic projection of the ground terminal G3 on the top plane P1 to at least partially overlap with the local portion of the grounding strip 130B in the axial direction L1, that is, The portion of the grounding piece 130B in the axial direction L1 shields at least a portion of the slot 114c at the side edge. Conversely, the opening 138 of the ground strip 130B exposes only a portion of the ground terminal G3, and the opening 138 of the ground strip 130A exposes only a portion of the ground terminal G1.

4A and 4B are cross-sectional views showing the electrical connector in different states, respectively, wherein the cut position of the plug electrical connector 100 is, for example, the A-A' line shown in FIG. 5 illustrates a partial cross-sectional view of the plug electrical connector, where portions of the ground piece 130A, 130B and the second component 114 of FIG. 5 are removed for identification. Referring to FIG. 4A, FIG. 4B and FIG. 5 simultaneously, in the embodiment, when the plug electrical connector 100 and the receptacle electrical connector 200 are docked with each other (as shown in FIG. 4B), the first terminal group 120A and the second terminal group 120B The elastic terminals are bent (elastically deformed) by the driving of the socket electrical connector 200, so that the structural features of the opening 138 of the grounding strips 130A, 130B in the axial direction L1 are located at the outermost grounding terminals G1 to G4. Therefore, the slot 114c is moved and abuts against the abutting portion 131 of the grounding pieces 130A, 130B. Further, the second member 114 further has a plurality of bearing portions 114e, and each of the bearing portions 114e is disposed in the slot 114c and located between the adjacent two ribs 114d. When the elastic terminals extend to the second member 114, the end portion of the elastic segment S2 will bear and be limited to the bearing portion 114e, as shown in FIGS. 4A and 5, until docked with the socket connector 200 (Fig. 4B), the elastic segment S2 is thus driven to move in the slot 114c, and thus is in contact with the abutting portion 131.

In other words, for the grounding strips 130A, 130B of the present embodiment, the portion thereof in the axial direction L1 (ie, the abutting portion 131) is on the deformable path of the grounding terminals G1 to G4, the deformable The path is a physical arrow as shown in FIG. 5, and is located between the bearing portion 114e and the abutting portion 131 of the grounding pieces 130A, 130B to provide a space for deformation of the ground terminals G1 to G4. Therefore, after the above-described butting operation, since the ground terminals G1 to G4 are in contact with the grounding pieces 130A and 130B, the two are electrically connected. In this way, the grounding strips 130A and 130B can thereby derive the noise current generated by the shielding effect via the ground terminals G1 to G4 to generate an electrical grounding effect on the grounding strips 130A and 130B. At the same time, the difference in state of contact and contact shown in FIG. 4A and FIG. 4B can also be reflected on the electrical signal between the grounding strips 130A, 130B and the ground terminals G1 G G4, that is, by the grounding strips 130A, 130B and The structure of the ground terminals G1 G G4 is contacted or not to cause an electrical trigger signal between the two. For example, the designer can make the electronic device with the electrical connector generate a corresponding function according to whether the electrical trigger signal is generated, for example, whether the electronic device is in a normal connection state, and thus can be applied to the technical field of electronic theft prevention and the like. It should be noted that, in this embodiment, the ground terminals G1 G G4 are abutted against the grounding strips 130A and 130B to achieve the desired signal change or grounding function, but actually one of the ground terminals G1 G G4 can be used. Abutting the grounding piece 130A or 130B, the desired effect can be achieved.

It should be noted that, although the abutting portion 131 shown in FIG. 5 partially shields the slot 114c of the outermost edge and the ground terminals G1 and G3 therein, the grounding terminal needs to be grounded in this embodiment. Under the premise that the connector is bent and deformed and thus contacts the grounding piece, in another embodiment not shown, the portion of the grounding piece in the axial direction L1 can completely shield the outermost slot, that is, The abutting portion 131 is extended in the axial direction L1 and abuts against the outermost rib 114d, and at the same time, the holding ability between the grounding piece and the insulator can be improved.

In summary, in the above embodiment of the present invention, the plug electrical connector is configured by the corresponding arrangement of the insulator, the elastic terminal and the grounding piece, so that the grounding piece is substantially positioned on the deformable path of the grounding terminal, and thus the socket is electrically When the connector and the plug electrical connector are docked with each other, the grounding terminal is bent and deformed by the driving of the electrical connector of the socket, and then abuts to the grounding piece to achieve electrical conduction, once the electrical connector of the plug and the electrical connector of the socket When separated from each other, the ground terminal is not bent due to elastic recovery, and thus is removed from the grounding piece. In this way, whether the grounding terminal contacts the grounding piece or not can electrically provide a conduction or non-conduction triggering effect, that is, similar to the switch, the designer can further provide additional use functions for the plug electrical connector. Its utility. At the same time, when the plug electrical connector is docked with the electrical connector of the socket, the grounding terminal and the grounding plate are electrically connected to provide a guiding effect on the noise.

Furthermore, since the grounding terminal is arranged at the outermost side of the remaining elastic terminals, the opening is only exposed to the outermost slot by forming an opening in the grounding piece and adjusting the size of the opening along the axial direction of the terminal arrangement. Partially or completely shielding the outermost slot, that is, the grounding piece partially shields the grounding terminal or completely shields the grounding terminal, so that the grounding terminal can smoothly contact the grounding piece during the bending process, thereby achieving structural contact The purpose of mutual electrical conduction.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the novel creation, and any person skilled in the art can make some changes without departing from the spirit and scope of the novel creation. Retouching, the scope of protection of this new creation is subject to the definition of the scope of the patent application attached.
