Description

Technical Field

[0001] The invention relates to a socket electrical connector. Background Art

[0002] The transmission interface specifications of electrical connectors are quite diverse, such as HDMI or Universal Serial Bus (USB). USB is gradually being used by the public and has developed from the USB 2.0 transmission specification to the current USB 3.0 transmission specification with a faster transmission speed.

[0003] The appearance, structure, terminal contact method, number of terminals, distance (Pitch) between each terminal, and pin assignment (Pin Assignment) of the existing USB Type-C electrical connector are completely different from the current USB electrical connector. The current USB Type-C socket electrical connector includes a plurality of flat terminals set on a rubber core, and the outside of the rubber core is covered with an outer iron shell and other structures. After long-term plugging and unplugging of the Type-C socket electrical connector and the Type-C plug electrical connector, the plurality of flat terminals of the Type-C socket electrical connector and the plurality of elastic terminals of the Type-C plug electrical connector contact and generate metal debris. The metal debris is easy to accumulate in the Type-C socket electrical connector. When the metal debris accumulates to a certain extent, it may occupy the gap between two adjacent plurality of flat terminals, causing indirect contact between adjacent terminals, thereby causing poor withstand voltage or even short circuit problems. Summary of the invention

[0004] The present invention provides a socket electrical connector, comprising an insulating body, a plurality of socket terminals and a shielding shell; the insulating body comprises a base and a tongue, the tongue extends from one side of the base, and a whole row of covering areas adjacent to the base is arranged on the surface of the tongue; the plurality of socket terminals are arranged on the upper surface of the base and the tongue or the lower surface of the tongue, the plurality of socket terminals comprise a connecting section arranged on the base and the tongue, a contact section extending from one side of the connecting section and located on the upper surface or the lower surface of the tongue, each socket terminal comprises a yielding portion located between the contact section and the connecting section, and the yielding portion of each socket terminal covers the whole row of covering areas of the tongue; and the shielding shell comprises a receiving groove, and the insulating body is arranged in the receiving groove.

[0005] In some embodiments, a plurality of plug terminals of the plug electrical connector respectively contact a plurality of socket terminals of the socket electrical connector, generating a plurality of debris on the entire row of coverage areas on the tongue surface of each of the yielding portions.

[0006] In some embodiments, the plug electrical connector is inserted into the receptacle electrical connector until it is positioned so that the plurality of contact ends of the plurality of plug terminals are adjacent to the entire row of footprints.

[0007] In some embodiments, the thickness of the socket terminals at each relief portion is less than the thickness of the socket terminals at each contact segment portion.

[0008] In some embodiments, each relief portion is located between the tongue piece and the base.

[0009] In some embodiments, the thickness of the base is greater than the thickness of the tongue piece, and one end of each relief portion of each socket terminal is located within the base.

[0010] In some embodiments, the entire row coverage area includes a plurality of partition portions respectively located between each relief portion.

[0011] In some embodiments, the entire row coverage area covers from the end of the contact segment to the end of the base.

[0012] In some embodiments, the entire row coverage area extends from one side of the tongue piece to the other side of the tongue piece.

[0013] In some embodiments, the surface of the tongue piece located in the entire row coverage area is substantially on the same horizontal plane as the surface of the contact segment.

[0014] An embodiment of the present invention provides the setting of the entire row coverage area. When the plurality of plug terminals of the plug electrical connector respectively contact the plurality of socket terminals of the socket electrical connector, a plurality of debris are generated on the entire row coverage area of the surface of the tongue piece on each relief portion. This avoids the poor voltage resistance or contact short - circuit between adjacent plural socket terminals and plural plug terminals caused by the accumulation of metal debris after the insertion and extraction of the plural socket terminals and the plural plug terminals. In addition, the area of the tongue piece made of plastic material wrapping the plurality of socket terminals becomes larger (increasing the coverage area of the entire row coverage area), avoiding the contact segments of the plurality of socket terminals of the socket electrical connector from warping and protruding from the surface of the tongue piece after processing and high - temperature baking.

[0079] Referring to Figures 1 to 7 , which is an embodiment of the socket electrical connector of the present invention, Figure 1 is a front external view schematic diagram of the socket electrical connector 100, Figure 2 is a first exploded schematic diagram of the front of the socket electrical connector 100, Figure 3 is a second exploded schematic diagram of the back of the socket electrical connector 100, Figure 4 is an exploded schematic diagram of a plurality of socket terminals 200, Figure 5 is a top view schematic diagram of a plurality of socket terminals 200, Figure 6 is a side sectional view schematic diagram, Figure 7 is a three-dimensional sectional view schematic diagram.

[0080] In this embodiment, the socket electrical connector 100 is a connection interface specification of USB (Type-C), but not limited thereto. In some embodiments, the socket electrical connector 100 can be a connection interface specification of HDMI. Here, the socket electrical connector 100 of USB (Type-C) is used for illustration. The socket electrical connector 100 includes an insulating body 1, a plurality of socket terminals 200, and a shielding housing 4.

[0081] In this embodiment, the insulating body 1 is a flat and long plate body, which can be composed of multiple parts or a single plastic seat. Here, the single insulating body 1 is used for illustration. The insulating body 1 includes a base 11 and a tongue piece 12, and the base 11 and the tongue piece 12 are formed by injection molding. The tongue piece 12 extends outward from one side of the base 11.

[0082] In this embodiment, the plurality of socket terminals 200 are arranged on the upper surface of the base 11 and the tongue piece 12 or the lower surface of the tongue piece 12.

[0083] In this embodiment, the shielding housing 4 is a hollow housing. The inside of the shielding housing 4 has a receiving groove 41. The shielding housing 4 covers the insulating body 1. That is, the insulating body 1 is arranged in the receiving groove 41. One end of the shielding housing 4 forms an insertion port 42 located at the periphery of the tongue piece 12. The other end of the shielding housing 4 extends a stop wall 43 that bends inward, and the stop wall 43 extends to the surface of the base 11.

[0084] In this embodiment, the stop wall 43 is substantially perpendicular to the surface of the base 11. An insertion space 40 is formed between the surface of the base 11 and the inner side surface of the shielding housing 4. The plug electrical connector 9 is inserted into the insertion space 40 from the insertion opening 42 (as Figure 9 shown); there is no insertion space formed between the surface of the base of the traditional socket electrical connector and the inner side surface of the shielding housing. The traditional plug electrical connector can only be inserted into the base and is blocked by the base and cannot be inserted into the insertion space.

[0085] Referring to Figure 2 、 Figure 7 and Figure 9 , Figure 9 is a side view schematic diagram of the docking of the socket electrical connector 100 and the plug electrical connector 9. In this embodiment, when the plug electrical connector 9 is inserted into the receiving groove 41, the end 9a of the plug electrical connector 9 contacts the stop wall 43, so that the shielding housing 4 (made of iron shell material) contacts the plug electrical connector 9. When the plug electrical connector 9 is inserted into the receiving groove 41 to the end, the force is dispersed to the shielding housing 4, avoiding the impact of the plug electrical connector 9 on the insulating body 1 and ensuring that the plurality of socket terminals 200 on the insulating body 1 will not be squeezed and deformed. It solves the problem that the general traditional socket electrical connector uses the insulating body (made of plastic material) as a resistance to the plug electrical connector, resulting in the impact on the insulating body and the extrusion and deformation of the plurality of socket terminals thereon.

[0086] In other words, the stop wall 43 (or the anti-retreat surface) of the socket electrical connector 100 in this embodiment is replaced by the shielding housing 4 (made of iron shell material) instead of the insulating body 1 (made of plastic material). The traditional socket electrical connector has a stop wall (or the anti-retreat surface) provided by the insulating body for the plug electrical connector to contact. Here, the plug electrical connector 9 includes an insulating seat body 91 and a housing 94 covering the outside of the insulating seat body 91. The end 9a of the insulating seat body 91 and the end 9a of the housing 94 contact the stop wall 43.

[0087] In this embodiment, the other end of the shielding housing 4 includes an extension portion 44 extending outward from the end of the stop wall 43. The extension portion 44 abuts against the surface of the base 11. The stop wall 43 and the extension portion 44 are substantially perpendicular. And, the extension portion 44 at the other end of the shielding housing 4 is a reduced frame opening structure 45. The inner diameter width of the reduced frame opening structure 45 is smaller than the inner diameter width of the insertion opening 42, forming a structural form with different sizes of the two end frame openings of the shielding housing 4.

[0088] Referring to Figure 1 and Figure 8 , Figure 8FIG. 0 is a schematic side cross-sectional view of another embodiment of the shielding housing 4. In this embodiment, the tongue piece 12 is exposed outside the insertion port 42, but not limited thereto. In some embodiments, the tongue piece 12 may be located inside the receiving groove 41. In other words, the length of the shielding housing 4 can be shortened so that the tongue piece 12 is exposed, or the length of the shielding housing 4 can be extended so that the tongue piece 12 is located inside the receiving groove 41. Since the shielding housing 4 can be changed to different lengths, the applicability for plugging in different specifications of the plug electrical connector 9 is increased (such as Figure 9 the specification of a plug electrical connector 9 shown), or in response to different assembled electronic product housings, shielding housings 4 of different lengths are used.

[0089] In this embodiment, the socket electrical connector 100 further includes a cover plate 6 covering the outside of the shielding housing 4. Grounding tabs extend from both sides of the cover plate 6 and are welded to the circuit board. Here, the cover plate 6 and the shielding housing 4 are in two pieces, but not limited thereto. In some embodiments, the cover plate 6 and the shielding housing 4 can be an integral member.

[0090] In this embodiment, the plurality of socket terminals 200 includes a plurality of first flat terminals 2. The plurality of first flat terminals 2 are located on the base 11 and the tongue piece 12. Here, the plurality of first flat terminals 2 includes a plurality of first flat signal terminals 21, at least one first flat power terminal 22, and at least one first flat ground terminal 23. Each first flat terminal 2 is disposed on the base 11 and the tongue piece 12 and is located on the upper surface.

[0091] In this embodiment, when viewed from the front of the plurality of first flat terminals 2, the plurality of first flat terminals 2 are, in order from left to right, the first flat ground terminal 23 (Gnd), the first flat power terminal 22 (Power / VBUS), a pair of first flat signal terminals 21 (D + -, differential signal terminals), a reserved terminal (RFU), and the rightmost first flat ground terminal 23 (Gnd), but not limited thereto.

[0092] In one embodiment, when viewed from the front of the plurality of first flat terminals 2, the plurality of first flat terminals 2 are, in order from left to right, the first flat ground terminal 23 (Gnd), the first pair of first flat signal terminals 21 (TX1 + -, differential signal terminals), the second pair of first flat signal terminals 21 (D + -, differential signal terminals), the third pair of first flat signal terminals 21 (RX2 + -, differential signal terminals), and the first flat power terminal 22 (Power / VBUS), the reserved terminal (RFU), and the rightmost first flat ground terminal 23 (Gnd) between the three pairs of first flat signal terminals 21. The specification is used to transmit USB3.0 signals.

[0093] Each first flat terminal 2 includes a first contact section 24, a first connection section 25, and a first welding section 26. The first connection section 25 is disposed on the base 11 and the tongue piece 12. The first contact section 24 extends from one side of the first connection section 25 and is located on the upper surface of the tongue piece. The first welding section 26 extends from the other side of the first connection section 25 and protrudes out of the base 11. A plurality of first flat signal terminals 21 are located on the upper surface of the tongue piece to transmit a set of first signals (i.e., USB2.0 signals). A plurality of first welding sections 26 protrude out of the rear side of the base 11. Moreover, the plurality of first welding sections 26 are horizontal and are used as surface mount pins (Surface Mount Technology, SMT), or the plurality of first welding sections 26 are bent to extend vertically downward and are used as through-hole pins (Through-hole Technology).

[0094] In this embodiment, the plurality of socket terminals 200 include a plurality of second flat terminals 3. The plurality of second flat terminals 3 are located on the base 11 and the tongue piece 12. Herein, the plurality of second flat terminals 3 include a plurality of second flat signal terminals 31, at least one second flat power terminal 32, and at least one second flat ground terminal 33. Each second flat terminal 3 is disposed on the base 11 and the tongue piece 12 and is located on the lower surface of the tongue piece 12.

[0095] In this embodiment, when viewed from the front of the plurality of second flat terminals 3, the plurality of second flat terminals 3 are, in order from right to left, the second flat ground terminal 33 (Gnd), the second flat power terminal 32 (Power / VBUS), a pair of second flat signal terminals 31 (D+-, differential signal terminals), a reserved terminal (RFU), and the second flat ground terminal 33 (Gnd) on the leftmost side, but not limited thereto.

[0096] In one embodiment, when viewed from the front of the plurality of second flat terminals 3, the plurality of second flat terminals 3 are, in order from right to left, the second flat ground terminal 33 (Gnd), the first pair of second flat signal terminals 31 (TX2+-, differential signal terminals), the second pair of second flat signal terminals 31 (D+-, differential signal terminals), the third pair of second flat signal terminals 31 (RX1+-, differential signal terminals), and the second flat power terminal 32 (Power / VBUS), the reserved terminal (RFU), and the second flat ground terminal 33 (Gnd) on the leftmost side between the three pairs of second flat signal terminals 31. The specification is used to transmit USB3.0 signals.

[0097] In this embodiment, a plurality of second flat terminals 3 are located on the base 11 and the tongue piece 12. Each second flat terminal 3 includes a second contact section 34, a second connection section 35, and a second welding section 36. The second connection section 35 is disposed on the base 11 and the tongue piece 12. The second contact section 34 extends from one side of the second connection section 35 and is located on the lower surface of the tongue piece 12. The second welding section 36 extends from the other side of the second connection section 35 and penetrates through the base 11. A plurality of second flat signal terminals 31 are located on the lower surface of the tongue piece 12 to transmit a set of second signals (i.e., USB2.0 signals). A plurality of second welding sections 36 penetrate through the rear side of the base 11. Moreover, the plurality of second welding sections 36 are in a horizontal shape and are used as surface mount pins (Surface Mount Technology, SMT), or the plurality of second welding sections 36 are bent to extend vertically downward and are used as through-hole pins (Through-hole Technology).

[0098] In this embodiment, from the arrangement manner of the plurality of first flat terminals 2 and the plurality of second flat terminals 3, it can be seen that the plurality of first flat terminals 2 and the plurality of second flat terminals 3 are respectively disposed on the upper surface and the lower surface of the tongue piece 12. Moreover, the plurality of first flat terminals 2 and the plurality of second flat terminals 3 are point-symmetric to each other with the center point of the accommodation groove 41 as the center of symmetry. The so-called point symmetry means that after rotating the plurality of first flat terminals 2 and the plurality of second flat terminals 3 by 180 degrees with the center of symmetry as the rotation center, the rotated plurality of first flat terminals 2 and the rotated plurality of second flat terminals 3 completely coincide. That is to say, the rotated plurality of first flat terminals 2 are located at the original arrangement positions of the plurality of second flat terminals 3, and the rotated plurality of second flat terminals 3 are located at the original arrangement positions of the plurality of first flat terminals 2.

[0099] In other words, the plurality of first flat terminals 2 and the plurality of second flat terminals 3 are upside down, and the arrangement manner of the plurality of first contact sections 24 is opposite to that of the plurality of second contact sections 34 in the left-right direction. Among them, the plug electrical connector 9 is inserted into the socket electrical connector 100 in the forward direction to transmit a set of first signals, and can also be inserted into the plug electrical connector 9 in the socket electrical connector 100 in the reverse direction to transmit a set of second signals. The transmission specification of a set of first signals conforms to the transmission specification of a set of second signals. It has the function of not restricting the forward or reverse insertion into the socket electrical connector 100 by the plug electrical connector 9 for transmission.

[0100] In this embodiment, from the front view of the plurality of first flat terminals 2 and the plurality of second flat terminals 3, the arrangement positions of the plurality of first flat terminals 2 correspond to the arrangement positions of the plurality of second flat terminals 3.

[0101] Refer to Figure 2 、 Figure 4 、 Figure 6, Figure 7 , Figures 9 to 12 , Figure 10 is a three-dimensional schematic diagram of the socket electrical connector 100 and the plug electrical connector 9 being docked. Figure 10 In it, the plug electrical connector 9 in Figure 11 is a three-dimensional schematic diagram of the tongue piece and the plug terminal 92 being docked. Figure 12 is an external view schematic diagram of the insulating body 1.

[0102] In this embodiment, a row of covering areas 13 adjacent to the base 11 are provided on the surface of the tongue piece 12. The thickness of the base 11 is slightly greater than the thickness of the tongue piece 12. The row of covering areas 13 are located between the base 11 and the tongue piece 12. Here, the row of covering areas 13 extend from one side of the tongue piece 12 to the other side of the tongue piece 12. That is, the row of covering areas 13 cover the inner surface of the tongue piece 12. The inner surface of the tongue piece 12 forms a row of covering areas 13 without the first contact section 24 and the second contact section 34 (the first contact section 24 or the second contact section 34 is the contact section). The row of covering areas 13 are not contact areas for the plug terminals 92 of the plug electrical connector 9. And, the surface of the tongue piece located in the row of covering areas is substantially on the same horizontal plane as the surface of the contact section.

[0103] In this embodiment, the plurality of socket terminals 200 include connection sections (the first connection section 25 or the second connection section 35) provided on the base 11 and the tongue piece 12, and contact sections (the first contact section 24 or the second contact section 34) extending from one side of the connection section and located on the upper surface or the lower surface of the tongue piece 12. Each socket terminal 200 includes a relief portion 29, 39 (as shown in Figure 4 ), and, the row of covering areas 13 include a plurality of partition portions 131 respectively located between the relief portions 29 and between the relief portions 39.

[0104] In this embodiment, the thickness of the socket terminals 200 at the positions of the relief portions 29, 39 are respectively less than the thickness of the socket terminals 200 at the positions of the contact sections (the first contact section 24 or the second contact section 34). And, the relief portions 29, 39 are respectively located between the tongue piece 12 and the base 11 (as shown in Figure 8 ), and the relief portions 29, 39 of each socket terminal 200 are covered by the row of covering areas 13 of the tongue piece 12. In this embodiment, the thickness of the base 11 is slightly greater than the thickness of the tongue piece 12, and one end of each relief portion 29, 39 of each socket terminal 200 is located inside the base 11.

[0105] In this embodiment, the range of the relief portion 29 of the first flat ground terminal 23 and the first flat power terminal 22 is larger than the range of the relief portion 29 of the first flat signal terminal 21. That is to say, the position width of the first flat ground terminal 23 and the first flat power terminal 22 in the relief portion 29 becomes larger, while the position width of the first contact section 24 of the first flat signal terminal 21 is the same as that of the relief portion 29, and the design of each terminal of the second flat terminal 3 is the same.

[0106] In this embodiment, when the plurality of plug terminals 92 of the plug electrical connector 9 respectively contact the plurality of socket terminals 200 of the socket electrical connector 100, metal friction generates a plurality of debris 99 on the upper and lower surfaces of the tongue piece 12 on each of the relief portions 29, 39 ( Figure 11 only indicating the upper surface of the tongue piece 12).

[0107] In particular, when the plurality of socket terminals 200 and the plurality of plug terminals 92 are in frictional contact, the metal debris 99 is easily accumulated in the area between the tongue piece 12 and the base 11. Therefore, by thinning the thickness of the socket terminals 200 at each of the relief portions 29, 39, when forming the insulating body 1, the tongue piece 12 made of a plastic material is covered on each of the relief portions 29, 39, so that the metal debris 99 is on the entire row of covering areas 13.

[0108] Avoid that after the plurality of socket terminals 200 and the plurality of plug terminals 92 are inserted and removed, the metal debris 99 accumulates, resulting in poor withstand voltage when the plug terminals 92 are inserted, or short circuit due to the contact of the metal debris 99 between the plurality of plug terminals 92 and the plurality of socket terminals 200, between the plurality of plug terminals 92, and between the plurality of socket terminals 200, that is, the short circuit caused by the conduction between terminals of different attributes.

[0109] The area of the tongue piece 12 made of a plastic material covering the plurality of socket terminals 200 becomes larger (increasing the covering area of the entire row of covering areas 13), avoiding the contact section (the first contact section 24 or the second contact section 34) of the plurality of socket terminals 200 of the socket electrical connector 100 from warping and protruding from the surface of the tongue piece 12 after processing and high-temperature baking.

[0110] In the traditional contact section of the plurality of socket terminals, it is arranged over the entire area of the tongue piece (without adding the covering area of a whole row of covering regions). The tongue piece made of plastic material is formed on the contact section of the plurality of socket terminals. After the thermal expansion and contraction in the processing procedure, small terminal slot holes are formed between the plastic and the metal. When conductive debris or water enters the terminal slot holes, it will cause poor voltage resistance or contact short circuit between adjacent plurality of socket terminals. In this embodiment, the covering area of the whole row of covering regions 13 is increased to avoid having terminal slot holes in the area of the whole row of covering regions 13, preventing conductive debris or water from entering the terminal slot holes and causing poor voltage resistance or contact short circuit between adjacent plurality of socket terminals 200. Moreover, when injection molding, there are no terminal slot holes blocking the flowing of the injected plastic, which can effectively improve the phenomenon of incomplete filling during molding and increase the strength of the socket electrical connector 100 product.

[0111] In this embodiment, the socket electrical connector 100 further includes a fixing block 15 (as shown in Figure 2 、 Figure 4 ). Comb-end holes are distributed and arranged on the fixing block 15. When the insulating body 1 is integrally molded (insert-molding) to combine each socket terminal 200 with the fixing block 15, the plastic can overflow from each comb-end hole, enabling the plastic to quickly cover the outer shape of the insulating body 1 and shortening the molding processing time. During injection molding, the whole row of covering regions 13 is designed without comb-end holes, avoiding the comb-end holes from blocking the flowing of the injected plastic, which can effectively improve the phenomenon of incomplete filling during molding and increase the strength of the socket electrical connector 100 product.

[0112] In this embodiment, each socket terminal 200 is positioned on the fixing block 15 and combined with the insulating body 1. Here, in the first molding processing procedure, each grounding piece 7 is combined with the fixing block 15. Then, each socket terminal 200 is placed and positioned on the fixing block 15. After that, in the second molding processing procedure, the insulating body 1 is molded outside each socket terminal 200 and the fixing block 15.

[0113] In other words, after the Type-C socket electrical connector 100 has been plugged and unplugged for a long time, inside the inner surface area of the tongue piece 12 of the insulating body 1, metal debris 99 generated by the frictional contact between the plurality of socket terminals 200 and the plurality of plug terminals 92 is likely to accumulate. When it accumulates to a certain extent, it may occupy the gap between two adjacent socket terminals 200, causing contact between the adjacent socket terminals 200, thereby leading to poor voltage resistance or even short circuit.

[0114] In this embodiment, when the plug electrical connector 9 is inserted into the socket electrical connector 100 to reach the positioning, the plurality of contact ends 923 of the plurality of plug terminals 92 are adjacent to the whole row of covering regions 13 and maintain a predetermined distance from the whole row of covering regions 13. After long-term plugging and unplugging, the metal debris 99 is pushed by the contact ends 923 to the position of the whole row of covering regions 13.

[0115] Refer to Figure 1 、 Figure 2, Figure 4 , Figure 5 , Figures 12 to 13 , Figure 13 is a schematic external view of the grounding piece 7 being buckled to the hook 95. In this embodiment, the socket electrical connector 100 includes a plurality of grounding pieces 7. Taking the plurality of grounding pieces 7 as an example for explanation, each grounding piece 7 is disposed on the insulating body 1, and each grounding piece 7 respectively includes a hook structure 71 protruding from both sides of the tongue piece 12, and a plurality of through holes 72 adjacent to each hook structure 71.

[0116] The plurality of grounding pieces 7 is not limited thereto. In some embodiments, the plurality of grounding pieces 7 may be an integral structure, that is, a single grounding piece 7 structure (as shown in Figure 14 ). Taking the single grounding piece 7 as an example for explanation, the grounding piece 7 is disposed on the insulating body 1, and both sides of the grounding piece 7 include a hook structure 71 protruding from both sides of the tongue piece 12, and a plurality of through holes 72 adjacent to each hook structure 71.

[0117] Taking the single grounding piece 7 as an example for explanation, the grounding piece 7 is located between the first flat terminal 2 and the second flat terminal 3, and the grounding piece 7 is formed on the insulating body 1 and between the plurality of first contact segments 24 and the plurality of second contact segments 34. By lengthening and widening the area of the grounding piece 7, the front end of the grounding piece 7 is adjacent to the front side surface of the tongue piece 12, and both sides of the front end of the grounding piece 7 protrude at both sides of the tongue piece 12 to provide contact for the plug electrical connector 100. Moreover, the grounding piece 7 is disposed on the tongue piece 12 to improve the strength and shielding effect of the tongue piece 12. That is to say, the function of the grounding piece 7 is that when the plurality of first contact segments 24 and the plurality of second contact segments 34 are transmitting signals, the problem of crosstalk signal interference can be improved by the isolation of the grounding piece 7. At the same time, the structural strength of the tongue piece 12 itself can also be improved by the grounding piece 7 located on the tongue piece 12.

[0118] In this embodiment, the plurality of hook structures 71 are respectively formed on the outer sides of the respective grounding pieces 7, and each hook structure 71 protrudes from both sides of the front end of the tongue piece 12. When the plug electrical connector 9 is inserted into the interior of the socket electrical connector 100, the hooks 95 on both sides of the plug electrical connector 9 will respectively latch onto the respective hook structures 71, which can prevent the hooks 95 on both sides of the plug electrical connector 9 from rubbing against both sides of the tongue piece 12 and causing wear of the tongue piece 12.

[0119] In this embodiment, the fixing block 15 protrudes outwardly with a plurality of blocking blocks 151 that clamp both sides of each socket terminal 200, and a positioning groove for positioning the socket terminal 200 is formed between the respective blocking blocks 151. And, a part of the plurality of blocking blocks 151 can be disposed in the respective through holes 72.

[0120] In this embodiment, each through hole 72 forms an expansion portion 721 extending toward the hook structure 71, increasing the space of each through hole 72 and the area where the plastic is molded on the expansion portion 721. Further, a plurality of stoppers 151 are respectively located at the positions of the through holes 72 and the expansion portions 721 (as Figure 5 shown), and the plurality of stoppers 151 are clamped on both sides of the front end of each socket terminal 200.

[0121] In this embodiment, the grounding plate 7 extends outward on both sides with an extension section 74 and a welding leg 75, and the fixing block 15 protrudes outward with a plurality of stoppers 151 clamped on both sides of each extension section 74, increasing the limit of different parts of the plurality of socket terminals 200 and the stability of the plurality of socket terminals 200 on the fixing block 15. In addition, the welding leg 75 passes through the rear of the base 11 and is welded to the circuit board to ground the grounding plate 7 for conduction.

[0122] In this embodiment, each grounding plate 7 forms a contact arm 711 on the outer side of each through hole 72, and a buckling recess 712 is formed on the outer side surface of the contact arm 711. When the plug electrical connector 9 is inserted into the socket electrical connector 100, the hooks 95 on both sides of the plug electrical connector 9 will latch onto the plurality of buckling recesses 712. During insertion and extraction, the hooks 95 contact the contact arm 711, and the contact arm 711 moves toward the inside of the through hole 72, forming an elastic deflection effect.

[0123] In other words, after the arrangement of each through hole 72 on each grounding plate 7, the hook structure 71 forms a hollow elastic structure. When the plug electrical connector 9 is docked with the socket electrical connector 100, the hooks 95 on both sides of the plug electrical connector 9 contact the hook structure 71, and the contact arm 711 of the hook structure 71 elastically deflects toward the inside of the through hole 72; avoiding the hard interference contact between the hooks 95 on both sides of the plug electrical connector 9 and the hook structure 71 when the plug electrical connector 9 is docked with the socket electrical connector 100, resulting in wear of the hooks 95 on both sides of the plug electrical connector 9, and serious wear may further cause structural damage and poor contact problems.
