[0061] In the description of this application, it should be understood that the terms “comprising” and “having” as used herein, and any variations thereof, are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are expressly listed, but may include other steps or units that are not expressly listed or that are inherent to such process, method, product, or apparatus.

[0062] Furthermore, for the sake of accuracy in the entire description of this application, all references to directions in this application shall be made in the form of... Figure 1 For reference, the X-axis direction is defined as the width direction; the Y-axis direction is defined as the docking direction; and the Z-axis direction is defined as the length direction.

[0063] Please refer to the reference. Figures 1 to 13 The image shows a mating female socket electrical connector 100 and a male plug electrical connector 200 disclosed in this application, which can be, for example, a heavy-duty power and signal hybrid connector.

[0064] The female socket connector 100 includes a female socket insulating housing 11, a plurality of female socket terminal pieces (not shown) fixed within the female socket insulating housing 11, and a female socket shielding member 14. The female socket insulating housing 11 is integrally injection molded from insulating material. One end of the female socket insulating housing 11 has an inwardly recessed first mating cavity 101 and a second mating cavity 102, separated by an insulating wall 103. The first mating cavity 101 and the second mating cavity 102 are used to mate with the male plug connector 200. The area where the first mating cavity 101 is located defines a first female socket area 111. The area where the second mating cavity 102 is located defines a second female socket area 112. The female socket terminal pieces include a plurality of first female socket contact terminals (not shown) fixed within the first female socket area 111 and a plurality of second female socket contact terminals (not shown) fixed within the second female socket area 112.

[0065] The insulating shell 11 of the female socket penetrates the inner bottom surface 1011 of the first mating cavity 101 along the mating direction, forming a first mounting groove 104, a second mounting groove 105, and a third mounting groove 106 for the female socket. The first mounting groove 104 is located near the insulating wall 103 (forming the inner surface of the first mating cavity 101 in close contact with the insulating wall 103). The second mounting groove 105 is located near the inner side 1012 of the first mating cavity 101 connected to the insulating wall 103. The third mounting groove 106 is located near the inner side 1013 of the first mating cavity 101 connected to the insulating wall 103.

[0066] The female socket shielding member 14 is formed from a single metal sheet through bending and stamping, and includes a first shielding plate 141, a second shielding plate 142, and a third shielding plate 143. In this embodiment, the first shielding plate 141 is perpendicular to both the second and third shielding plates 142 and 143. The first shielding plate 141 is inserted and fixed into the first mounting groove 104 of the female socket. The second shielding plate 142 is inserted and fixed into the second mounting groove 105. The third shielding plate 143 is inserted and fixed into the third mounting groove 106. The female socket shielding member 14 provides multi-directional isolation between the first contact terminal of the female socket arranged in the first region 111 and the second contact terminal of the female socket arranged in the second region 112, preventing mutual interference between the first and second contact terminals.

[0067] In this application, the female socket shielding member 14 is assembled and fixed to the female socket insulating housing 11. Specifically, a first reserved gap 15 is formed at the bend of the first shielding plate 141 and the second shielding plate 142 of the female socket, and the insulating housing 11 correspondingly forms a first connecting portion 1101 of the female socket that is inserted into and limited to the first reserved gap 15. A second reserved gap 16 is formed at the bend of the second shielding plate 142 and the third shielding plate 143 of the female socket, and the insulating housing 11 correspondingly forms a second connecting portion 1102 that is inserted into and limited to the second reserved gap 16.

[0068] Preferably, the first reserved gap portion 15 and the second reserved gap portion 16 of the female socket are formed at the front end of the female socket shielding member 14 assembled and inserted into the female socket insulating housing 11 and extend along the mating direction. This ensures that the portion of the female socket insulating housing 11 inside the first mating cavity 101 of the female socket is not disconnected and isolated, and that the portion of the female socket insulating housing 11 inside the first mating cavity 101 of the female socket forms connections with the portion of the female socket insulating housing 11 outside the first mating cavity 101 at at least three locations: the position of the portion of the female socket insulating housing 11 inside the first mating cavity 101 away from the insulating wall 103 along the length direction, the position of the first joint portion 1101 of the female socket, and the position of the second joint portion 1102 of the female socket. This prevents the portion of the female socket insulating housing 11 inside the first mating cavity 101 of the female socket from deflecting, twisting, or even breaking when pressed by external force.

[0069] Furthermore, in a preferred embodiment, an elastic limiting piece 140 is formed on the female socket shielding member 14. After the female socket shielding member 14 is assembled into the female socket insulating housing 11, the elastic limiting piece 140 is correspondingly elastically engaged in the snap-fit ​​groove 1010 formed on the inner wall of the first mating cavity 101 of the female socket in the female socket insulating housing 11, so as to realize the assembly and fixation between the female socket shielding member 14 and the female socket insulating housing 11. In addition, the front edge of the first shielding piece 141, the second shielding piece 142, and the third shielding piece 143 of the female socket is folded back to form a folded portion 17 along the mating direction. The folded portion 17 is correspondingly hung on the front edge of the female socket insulating housing 11 along the mating direction. In this application, the extension length of the first shielding piece 141, the second shielding piece 142, and the third shielding piece 143 of the female socket along the mating direction of the mating connector covers the entire length of the female socket insulating housing 11, preferably exceeding the maximum length of the female socket insulating housing 11.

[0070] Please refer to Figures 1 to 6 As shown in the figure, in this application, the female socket electrical connector 100 further includes a cable fastener 18, which has a first side fastener 181 and a second side fastener 182. The first side fastener 181 and the second side fastener 182 are fastened together in a transverse direction perpendicular to the mating direction. The front edges of the first side fastener 181 and the second side fastener 182 along the mating direction are locked with the corresponding rear edges of the first shielding plate 141, the second shielding plate 142 and the third shielding plate 143 of the female socket by nuts. The first side fastener 181 and the second side fastener 182 form an enlarged space portion 1801 at the front end portion in the mating direction and a constricted space portion 1802 at the rear end portion in the mating direction. The cross-sectional area of ​​the constricted space portion 1802 along the mating direction is smaller than that of the enlarged space portion 1801. Preferably, the first side fastener 181 extends from the end of the tightening space 1802 in a transverse direction perpendicular to the docking direction to form a locking wing 1803, and the second side fastener 182 extends from the end of the tightening space 1802 in a transverse direction perpendicular to the docking direction to form a mating wing 1804. The locking wing 1803 and the mating wing 1804 are attached to each other and locked by a nut. The cable fastener 18 is mainly used to fasten the cable (not shown) connected to the first contact terminal of the female socket, and also to isolate the connection position between the first contact terminal of the female socket and the cable from the outside.

[0071] Please refer to Figures 7 to 13As shown, the male plug electrical connector 200 includes a male plug insulating housing 21, a plurality of male plug terminals (not shown) fixed within the male plug insulating housing 21, and a male plug shielding member 24. The male plug insulating housing 21 is integrally injection molded from an insulating material. Specifically, the male plug insulating housing 21 includes an insulating base 201 and a first mating tongue 202 and a second mating tongue 203 extending from one end of the insulating base 201 along the mating direction. The first mating tongue 202 and the second mating tongue 203 are spaced apart along their length to form mating seams 207. The area where the first mating tongue 202 is located defines a first male plug region 211, and the area where the second mating tongue 203 is located defines a second male plug region 212. The male plug terminals include a plurality of first male plug contact terminals (not shown) and a plurality of second male plug contact terminals (not shown). The first contact terminal of the male plug is fixed within the first region 211 of the male plug, and the second contact terminal of the male plug is fixed within the second region 212 of the plug. During mating, the first mating tongue 202 is inserted into the first mating cavity 101 of the female socket, the second mating tongue 203 is inserted into the second mating cavity 102 of the female socket, and the insulating wall 103 is inserted and secured within the mating seam 207.

[0072] Furthermore, the male plug insulating shell 21 extends through the insulating base 201 along the mating direction to form a first male plug mounting groove 204, a second male plug mounting groove 205, and a third male plug mounting groove 206. The first male plug mounting groove 104 is located within the mating seam 207 and near the first mating tongue 202 (closely attached to the surface of the first mating tongue 202 near the second mating tongue 203). The second mounting groove 205 is close to one end face of the first mating tongue 202 along the width direction. The third mounting groove 106 is close to the other end face of the first mating tongue 202 along the width direction.

[0073] The male plug shielding member 24 is formed from a single metal sheet through bending and stamping, and includes a first shielding plate 241, a second shielding plate 242, and a third shielding plate 243. The first shielding plate 241 is inserted and fixed into the first mounting groove 204 of the male plug. The second shielding plate 242 is inserted and fixed into the second mounting groove 205 of the male plug. The third shielding plate 243 is inserted and fixed into the third mounting groove 206 of the male plug. The male plug shielding member 24 provides multi-directional isolation between the first contact terminal of the male plug arranged in the first region 211 and the second contact terminal of the male plug arranged in the second region 212 of the male plug, preventing mutual interference between the first and second contact terminals.

[0074] In this application, the male plug shielding member 24 is also assembled and fixed into the male plug insulating housing 21. Specifically, a first reserved gap 25 is formed at the bend of the first shielding plate 241 and the second shielding plate 242 of the male plug, and the insulating housing 21 of the male plug correspondingly forms a first connecting portion 2101 of the male plug that is inserted into and limited to the first reserved gap 25. A second reserved gap 26 is formed at the bend of the second shielding plate 242 and the third shielding plate 243 of the male plug, and the insulating housing 21 of the male plug correspondingly forms a second connecting portion 2102 of the male plug that is inserted into and limited to the second reserved gap 26.

[0075] Preferably, the first reserved gap portion 25 and the second reserved gap portion 26 of the male plug are formed at the front end position of the male plug shielding member 24 assembled and inserted into the male plug insulating shell 21 and extend along the mating direction. This ensures that the portion of the male plug insulating shell 21 in the first region 211 of the male plug is not disconnected and isolated, and that the portion of the male plug insulating shell 21 in the first region 211 of the male plug forms connections with the portion of the male plug insulating shell 21 outside the first region 211 of the male plug at least in three positions: the portion of the male plug insulating shell 21 in the first region 211 of the male plug (that is, the portion of the male plug insulating shell 21 located behind the first mating tongue portion 202 along the positive Y-axis) on the side away from the mating seam 207 along the length direction, the position of the first joint portion 2101 of the male plug, and the position of the second joint portion 2102 of the male plug. This prevents the portion of the male plug insulating shell 21 in the first region 211 of the male plug from deflecting, twisting, or even breaking when pressed by external force.

[0076] Combination Figures 9 to 11 As shown, in a preferred embodiment, the male plug shielding member 24 is further provided with a plurality of connecting portions 244, which may be raised spring tabs or convex structures. After the male plug shielding member 24 is assembled into the male plug insulating housing 21, the connecting portions 244 are engaged and fixed with mating portions 2001 formed on the inner wall surfaces of the first mounting groove 204, the second mounting groove 205, and the third mounting groove 206 of the male plug insulating housing 21. Specifically, the mating portions 2001 may be groove structures recessed inward from the corresponding inner wall surface, or cantilevered elastic hook structures formed at intervals on the inner wall surface with one end integrally connected to the inner wall surface. This achieves the assembly and fixation between the male plug shielding member 24 and the male plug insulating housing 21.

[0077] In some embodiments, the first shielding plate 241, the second shielding plate 242, and the third shielding plate 243 of the male plug are folded back along the mating direction to form a folded portion (not shown, similar to the folded-back portion 17 structure on the female socket electrical connector 100). The folded portion is correspondingly attached to the front edge of the male plug insulating housing 21 along the mating direction. In this application, the extension length of the first shielding plate 241, the second shielding plate 242, and the third shielding plate 243 of the male plug along the mating direction of the mating connector covers the entire length of the male plug insulating housing 21, preferably exceeding the maximum length of the male plug insulating housing 21. When the female socket electrical connector 100 and the male plug electrical connector 200 are mated, the female socket shielding member 14 is correspondingly attached to the male plug shielding member 24 to form an electrical contact. Of course, in order to make the contact more stable, a raised contact spring structure (not labeled) can also be added at the contact surface of the female socket shielding member 14 and the male plug shielding member 24.

[0078] In the high-shield electrical connector of this application, the first contact terminal arranged in the first region 111, 211 is usually a power contact terminal, and the second contact terminal arranged in the second region 112, 212 is usually a signal contact terminal. Through the design scheme of this application, the power contact terminal and the signal contact terminal can be completely isolated from each other, reducing or even eliminating the mutual interference between the power transmission of the power contact terminal and the signal transmission of the signal contact terminal, thereby reducing or even eliminating the influence of power transmission on signal transmission. At the same time, it can ensure the overall structural stability of the female socket electrical connector 100 and the male plug electrical connector 200, and will not affect the structural strength of the female socket insulating shell 11 and the male plug insulating shell 21 due to the addition of the female socket shielding member 14 and the male plug shielding member 24. The overall structural design of the female socket shielding member 14 and the male plug shielding member 24 can achieve shielding and isolation effects on the contact terminals in the corresponding regions at multiple angles and directions.

[0079] As a general design concept disclosed in this application, the high-shield structure electrical connector in this application can refer to the female socket electrical connector 100 or the male plug electrical connector 200.
