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 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, the outside of the rubber core is covered with an outer iron shell and other structures, and metal sheets are exposed on both sides of the rubber core. When the Type-C plug electrical connector is docked with the Type-C socket electrical connector, the hooks on both sides of the Type-C plug electrical connector interfere with the metal sheet, causing the hooks on both sides of the Type-C plug electrical connector to wear. Severe wear will cause structural damage and insufficient insertion and extraction force. Summary of the invention

[0004] The present invention provides a socket electrical connector, comprising an insulating body, a plurality of socket terminals, a metal sheet and a shielding shell; the insulating body comprises a base and a tongue, the tongue extending from one side of the base, metal sheets are arranged on both sides of the tongue, the metal sheets comprise a hook structure protruding from the side of the tongue, and a through hole adjacent to the hook structure; 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 shielding shell comprises a receiving groove, and the insulating body is arranged in the receiving groove.

[0005] In some embodiments, the metal sheets on both sides of the tongue are integral structures or separate components.

[0006] In some embodiments, a fixing block is further included, and each socket terminal is positioned on the fixing block and combined with the insulating body.

[0007] In some embodiments, the fixing block protrudes outwardly with a plurality of stoppers clamped on both sides of each socket terminal.

[0008] In some embodiments, a plurality of stoppers are disposed in each through hole.

[0009] In some embodiments, the metal sheet has extension sections and welding legs extending outwardly from both sides, and the fixing block has a plurality of stoppers protruding outwardly and clamped on both sides of each extension section.

[0010] In some embodiments, each through hole forms an expansion portion extending toward the hook structure.

[0011] In some embodiments, the metal sheet forms a contact arm outside each through hole.

[0012] In some embodiments, a snap-fit ​​recess is formed on the outer side of the contact arm.

[0013] In some embodiments, a plurality of stoppers are respectively disposed at the through hole and the expansion portion.

[0014] An embodiment of the invention provides a through hole arrangement on a metal sheet to form an elastic contact arm. When the plug electrical connector is mated with the socket electrical connector, the hooks on both sides of the plug electrical connector contact the hook structure on the metal sheet, and the contact arm of the hook structure elastically deflects toward the through hole. This prevents the hooks on both sides of the plug electrical connector from interfering with the hook structure when the plug electrical connector is mated with the socket electrical connector, causing wear of the hooks on both sides of the plug electrical connector. Severe wear may cause structural damage and insufficient insertion and extraction force. BRIEF DESCRIPTION OF THE DRAWINGS

[0078] Reference Figures 1 to 7 , is an embodiment of the socket electrical connector of the present invention, Figure 1 is a schematic diagram of the front appearance of the socket electrical connector 100, Figure 2 is an exploded schematic diagram of the front side of the socket electrical connector 100 (I), Figure 3 The exploded view of the back of the socket electrical connector 100 (II) is shown. Figure 4 is an exploded schematic diagram of a plurality of socket terminals 200, Figure 5 is a top view of a plurality of socket terminals 200, Figure 6 A side cross-sectional diagram. Figure 7It is a three-dimensional cross-sectional schematic diagram.

[0079] In this embodiment, the socket electrical connector 100 is a USB (Type-C) connection interface specification, but it is not limited thereto. In some embodiments, the socket electrical connector 100 may be a HDMI connection interface specification. Here, the USB (Type-C) socket electrical connector 100 is used for illustration. The socket electrical connector 100 includes an insulating body 1, a plurality of socket terminals 200, and a shielding shell 4.

[0080] In this embodiment, the insulating body 1 is a flat and long plate, which can be composed of multiple pieces or a single plastic base. Here, a single-piece insulating body 1 is used for illustration. The insulating body 1 includes a base 11 and a tongue 12. The tongue 12 extends outward from one side of the base 11. Metal sheets 7 are arranged on both sides of the tongue 12. The metal sheet 7 includes a hook structure 71 protruding from the side of the tongue 12, and a through hole 72 adjacent to the hook structure 71.

[0081] In this embodiment, the plurality of socket terminals 200 are disposed on the upper surface of the base 11 and the tongue piece 12 or the lower surface of the tongue piece 12 .

[0082] In this embodiment, the shielding shell 4 is a hollow shell, and the shielding shell 4 has a receiving groove 41 inside. The shielding shell 4 covers the insulating body 1, that is, the insulating body 1 is disposed in the receiving groove 41. An insertion port 42 is formed at one end of the shielding shell 4 at the outer position of the tongue piece 12, and a stop wall 43 bent inwardly is extended from the other end of the shielding shell 4, and the stop wall 43 extends to the surface of the base 11.

[0083] In this embodiment, the stop wall 43 is substantially perpendicular to the surface of the base 11, and an insertion space 40 is formed between the surface of the base 11 and the inner side of the shielding shell 4. The plug electrical connector 9 is inserted into the insertion space 40 through the insertion port 42 (such as Fig. 9 As shown); there is no insertion space formed between the base surface of the conventional socket electrical connector and the inner side surface of the shielding shell, and the conventional plug electrical connector can only be inserted into the base and cannot be inserted into the insertion space due to the stop of the base.

[0084] Reference Figure 2 , Figure 7 and Fig. 9 , Fig. 9It 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 shell 4 (iron shell material) contacts the plug electrical connector 9. When the plug electrical connector 9 is inserted into the receiving groove 41 to the bottom, the force is dispersed to the shielding shell 4 to prevent the insulating body 1 from being hit by the plug electrical connector 9, ensuring that the multiple socket terminals 200 on the insulating body 1 will not be squeezed or deformed. It solves the problem that the conventional socket electrical connector uses the insulating body (plastic material) as a means of resisting the plug electrical connector, causing the insulating body to be hit and the multiple socket terminals thereon to be squeezed and deformed.

[0085] In other words, the stop wall 43 (or stop surface) of the socket electrical connector 100 of this embodiment is replaced by the shielding shell 4 (iron shell material) instead of the insulating body 1 (plastic material). In the conventional socket electrical connector, the stop wall (or stop surface) provided by the insulating body is contacted by the plug electrical connector. Here, the plug electrical connector 9 includes an insulating seat body 91 and a shell 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 shell 94 contact the stop wall 43.

[0086] In this embodiment, the other end of the shielding shell 4 includes an extension portion 44 extending outward from the end of the stop wall 43, and the extension portion 44 is in contact with the surface of the base 11. The stop wall 43 and the extension portion 44 are substantially perpendicular. In addition, the extension portion 44 at the other end of the shielding shell 4 is a reduced frame opening structure 45, and the inner diameter width of the reduced frame opening structure 45 is smaller than the inner diameter width of the plug port 42, forming a structural form in which the frame openings at the two ends of the shielding shell 4 are of different sizes.

[0087] Reference Figure 1 and Figure 8 , Figure 8 FIG. 4 is a side cross-sectional diagram of another embodiment of the shielding shell 4. In this embodiment, the tongue 12 is exposed outside the plug-in port 42, but this is not limited to this. In some embodiments, the tongue 12 can be located inside the receiving groove 41. In other words, the length of the shielding shell 4 can be shortened to allow the tongue 12 to be exposed, or the length of the shielding shell 4 can be extended to allow the tongue 12 to be located inside the receiving groove 41. Since the shielding shell 4 can be changed to different lengths, the applicability of plugging in different plug electrical connectors 9 specifications is increased (such as Fig. 9 A plug electrical connector 9 is shown in the figure), or shielding shells 4 of different lengths are used in response to different assembled electronic product shells.

[0088] In this embodiment, the socket electrical connector 100 further includes a cover plate 6, which covers the outside of the shielding shell 4, and the extension pieces on both sides of the cover plate 6 are welded to the circuit board. Here, the cover plate 6 and the shielding shell 4 are two-piece, but this is not limited to this. In some embodiments, the cover plate 6 and the shielding shell 4 can be an integrated component.

[0089] In this embodiment, the plurality of socket terminals 200 include a plurality of first flat terminals 2, and the plurality of first flat terminals 2 are located on the base 11 and the tongue 12. Here, the plurality of first flat terminals 2 include 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, and each first flat terminal 2 is arranged on the base 11 and the tongue 12 and is located on the upper surface.

[0090] In this embodiment, from the front view of the plurality of first plate terminals 2, the plurality of first plate terminals 2 are, from left to right, a first plate ground terminal 23 (Gnd), a first plate power terminal 22 (Power / VBUS), a pair of first plate signal terminals 21 (D+-, differential signal terminals), a reserved terminal (RFU) and the first plate ground terminal 23 (Gnd) on the far right, but the present invention is not limited thereto.

[0091] In one embodiment, when viewed from the front of the plurality of first flat terminals 2, the plurality of first flat terminals 2 are, from left to right, a first flat ground terminal 23 (Gnd), a first pair of first flat signal terminals 21 (TX1+-, differential signal terminals), a second pair of first flat signal terminals 21 (D+-, differential signal terminals), a third pair of first flat signal terminals 21 (RX2+-, differential signal terminals), and a first flat power terminal 22 (Power / VBUS) between the three pairs of first flat signal terminals 21, a reserved terminal (RFU) and the first flat ground terminal 23 (Gnd) on the far right, and the specifications are used to transmit USB3.0 signals.

[0092] 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 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. The first welding section 26 extends from the other side of the first connection section 25 and passes through the base 11. The plurality of first flat signal terminals 21 are located on the upper surface of the tongue and transmit a set of first signals (i.e., USB2.0 signals). The plurality of first welding sections 26 pass through the rear side of the base 11. In addition, the plurality of first welding sections 26 are horizontal and used as surface mount pins (Surface Mount Technology, SMT), or the plurality of first welding sections 26 are bent to extend vertically downward and used as vertical pins (Through-hole Technology). .

[0093] In this embodiment, the plurality of socket terminals 200 include a plurality of second flat terminals 3, and the plurality of second flat terminals 3 are located on the base 11 and the tongue 12. Here, 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, and each second flat terminal 3 is arranged on the base 11 and the tongue 12 and is located on the lower surface of the tongue 12.

[0094] In this embodiment, from the front view of the plurality of second plate terminals 3, the plurality of second plate terminals 3 are, from the right to the left, a second plate ground terminal 33 (Gnd), a second plate power terminal 32 (Power / VBUS), a pair of second plate signal terminals 31 (D+-, differential signal terminals), a reserved terminal (RFU) and the leftmost second plate ground terminal 33 (Gnd), but the present invention is not limited thereto.

[0095] In one embodiment, when viewed from the front, the plurality of second flat terminals 3 are, from the right side to the left side, a second flat ground terminal 33 (Gnd), a first pair of second flat signal terminals 31 (TX2+-, differential signal terminals), a second pair of second flat signal terminals 31 (D+-, differential signal terminals), a third pair of second flat signal terminals 31 (RX1+-, differential signal terminals), and a second flat power terminal 32 (Power / VBUS) between the three pairs of second flat signal terminals 31, a reserved terminal (RFU) and a second flat ground terminal 33 (Gnd) on the far left, and the specification is used to transmit USB3.0 signals.

[0096] In this embodiment, the plurality of second flat terminals 3 are located on the base 11 and the tongue 12. Each second flat terminal 3 includes a second contact section 34, a second connecting section 35 and a second welding section 36. The second connecting section 35 is disposed on the base 11 and the tongue 12. The second contact section 34 extends from one side of the second connecting section 35 and is located on the lower surface of the tongue 12. The second welding section 36 extends from the other side of the second connecting section 35 and passes through the base 11. The plurality of second flat signal terminals 31 are located on the lower surface of the tongue 12 and transmit a set of second signals (i.e., USB2.0 signals). The plurality of second welding sections 36 pass through the rear side of the base 11. In addition, the plurality of second welding sections 36 are horizontal and used as surface mount pins (Surface Mount Technology, SMT), or the plurality of second welding sections 36 are bent to extend vertically downward and used as vertical pins (Through-hole Technology).

[0097] In this embodiment, it can be seen from the arrangement of the plurality of first flat terminals 2 and the plurality of second flat terminals 3 that the plurality of first flat terminals 2 and the plurality of second flat terminals 3 are respectively arranged on the upper surface and the lower surface of the tongue 12, and the plurality of first flat terminals 2 and the plurality of second flat terminals 3 are point symmetrical to each other with the center point of the receiving groove 41 as the symmetry center. The so-called point symmetry means that after the plurality of first flat terminals 2 and the plurality of second flat terminals 3 are rotated 180 degrees based on the symmetry center as the rotation center, the rotated plurality of first flat terminals 2 and the plurality of second flat terminals 3 completely overlap, that is, the rotated plurality of first flat terminals 2 are located at the original arrangement position of the plurality of second flat terminals 3, and the rotated plurality of second flat terminals 3 are located at the original arrangement position of the plurality of first flat terminals 2.

[0098] In other words, the plurality of first flat terminals 2 and the plurality of second flat terminals 3 are upside down, and the arrangement of the plurality of first contact sections 24 is opposite to the arrangement of the plurality of second contact sections 34. The plug electrical connector 9 is forwardly plugged into the interior of the socket electrical connector 100 to transmit a set of first signals, and can also be reversely plugged into the interior of the socket electrical connector 100 to transmit a set of second signals, and the transmission specification of the set of first signals is consistent with the transmission specification of the set of second signals. It has the function of not limiting the forward or reverse plugging of the plug electrical connector 9 into the interior of the socket electrical connector 100 for transmission.

[0099] In this embodiment, from the front view of the plurality of first plate terminals 2 and the plurality of second plate terminals 3 , the arrangement positions of the plurality of first plate terminals 2 correspond to the arrangement positions of the plurality of second plate terminals 3 .

[0100] Reference Figure 2 , Figure 4 , Figure 6 , Figure 7 , Figures 9 to 12 , Fig.10 It is a three-dimensional schematic diagram of the docking of the socket electrical connector 100 and the plug electrical connector 9. Fig.10 The plug electrical connector 9 is cut off in half. Fig.11 It is a three-dimensional schematic diagram of the tongue piece and the plug terminal 92 being connected. Fig.12 It is a schematic diagram of the appearance of the insulating body 1.

[0101] In this embodiment, a whole row of covering areas 14 adjacent to the base 11 is provided on the surface of the tongue 12, the thickness of the base 11 is slightly greater than that of the tongue 12, and the whole row of covering areas 14 is located between the base 11 and the tongue 12. Here, the whole row of covering areas 14 extends from one side of the tongue 12 to the other side of the tongue 12, that is, the whole row of covering areas 14 is spread over the inner surface of the tongue 12, and the inner surface of the tongue 12 forms a whole row of covering areas 14 without the first contact section 24 and the second contact section 34, and the whole row of covering areas 14 is the contact area of ​​the plug terminal 92 of the non-plug electrical connector 9.

[0102] In this embodiment, the plurality of socket terminals 200 include a connecting section (a first connecting section 25 or a second connecting section 35) disposed on the base 11 and the tongue 12, a contact section (a first contact section 24 or a second contact section 34) extending from one side of the connecting section and located on the upper surface or the lower surface of the tongue 12, and each socket terminal 200 includes a clearance portion 29, 39 (such as Figure 4 as shown).

[0103] In this embodiment, the thickness of the socket terminal 200 at each of the clearance portions 29 and 39 is smaller than the thickness of the socket terminal 200 at each of the contact sections (the first contact section 24 or the second contact section 34). Figure 8 As shown in FIG. 1 ), the yielding portions 29 and 39 of each socket terminal 200 cover the entire row of coverage areas 14 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 yielding portion 29 and 39 of each socket terminal 200 is located in the base 11.

[0104] In this embodiment, the range of the concession portion 29 of the first flat ground terminal 23 and the first flat power terminal 22 is larger than the range of the concession portion 29 of the first flat signal terminal 21, that is, the width of the first flat ground terminal 23 and the first flat power terminal 22 at the position of the concession portion 29 becomes larger, while the first contact section 24 of the first flat signal terminal 21 is consistent with the position width of the concession portion 29, and the design of each terminal of the second flat terminal 3 is the same.

[0105] 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, the metal friction generates a plurality of debris 99 on the upper and lower surfaces of the tongue pieces 12 on the respective accommodating portions 29 and 39 ( Fig.11 Only the upper surface of the tongue 12 is shown).

[0106] In particular, when the plurality of socket terminals 200 and the plurality of plug terminals 92 are in frictional contact, 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 terminal 200 at each of the easing portions 29 and 39, when molding the insulating body 1, the tongue piece 12 made of plastic material is covered on each of the easing portions 29 and 39, so that the metal debris 99 is on the entire row of the covering area 13.

[0107] This prevents the accumulation of metal debris 99 after the plurality of socket terminals 200 and the plurality of plug terminals 92 are plugged in and out, causing the adjacent plurality of plug terminals 92 to have poor withstand voltage when the plug terminal 92 is inserted, or the plurality of plug terminals 92 and the plurality of socket terminals 200, the plurality of plug terminals 92, and the plurality of socket terminals 200 to short-circuit due to contact due to the metal debris 99, that is, terminals with different properties are connected and short-circuited.

[0108] The area covered by the plastic tongue 12 of the plurality of socket terminals 200 is increased (the coverage area of ​​the entire row of covering areas 13 is increased), so as to prevent the contact sections (first contact sections 24 or second contact sections 34) of the plurality of socket terminals 200 of the socket electrical connector 100 from being lifted and protruding from the surface of the tongue 12 after processing and high-temperature baking.

[0109] The contact section of the conventional multiple socket terminals is set on the area of ​​the entire tongue piece (without adding the covering area of ​​the whole row covering area), and the tongue piece of plastic material is molded on the contact section of the multiple socket terminals. After the thermal expansion and contraction of the processing procedure, a small terminal slot hole is formed between the plastic and the metal. The entry of conductive debris or water into the terminal slot hole causes the adjacent multiple socket terminals to have poor withstand voltage or short circuit. This embodiment adds the covering area of ​​the whole row covering area 13 to avoid the terminal slot hole in the whole row covering area 13 area, avoid the entry of conductive debris or water into the terminal slot hole, causing the adjacent multiple socket terminals 200 to have poor withstand voltage or short circuit, and there is no terminal slot hole to block the flow of the injected plastic during injection molding, which can effectively improve the phenomenon of unsaturated mold during molding and increase the strength of the socket electrical connector 100 product.

[0110] In this embodiment, the socket electrical connector 100 further includes a fixing block 15 (such as Figure 2 , Figure 4 As shown in FIG. 1 , comb-end holes are distributed and arranged on the fixing block 15. When the insulating body 1 is combined with each socket terminal 200 and the fixing block 15 during insert-molding, the plastic can overflow from each comb-end hole, allowing the plastic to quickly fill the shape of the insulating body 1, thereby shortening the molding process time. During injection molding, the entire row of covering areas 13 is designed without comb-end holes to prevent the comb-end holes from blocking the flow of the injected plastic, which can effectively improve the phenomenon of incomplete mold during molding and increase the strength of the socket electrical connector 100 product.

[0111] In this embodiment, each socket terminal 200 is positioned on the fixed block 15 and combined with the insulating body 1. Here, in the first molding process, each metal sheet 7 is combined with the fixed block 15, and then each socket terminal 200 is placed and positioned on the fixed block 15. Then, a second molding process is performed to mold the insulating body 1 outside each socket terminal 200 and the fixed block 15.

[0112] In other words, after long-term plugging and unplugging, the metal debris 99 of the Type-C socket electrical connector 100 caused by frictional contact between the plurality of socket terminals 200 and the plurality of plug terminals 92 is prone to accumulation in the inner area of ​​the surface of the tongue 12 of the insulating body 1. When accumulated to a certain extent, it may occupy the gap between two adjacent socket terminals 200, causing the adjacent socket terminals 200 to contact, thereby causing poor withstand voltage or even a short circuit.

[0113] In this embodiment, the plug electrical connector 9 is inserted into the socket electrical connector 100 to reach the position, and the multiple contact ends 923 of the multiple plug terminals 92 are adjacent to the entire row of covering areas 13 and maintain a predetermined distance from the entire row of covering areas 13. After long-term plugging and unplugging, the metal debris 99 is pushed to the position of the entire row of covering areas 13 by the contact ends 923.

[0114] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 12 to Figure 13 , Fig.13 9 is a schematic diagram of the appearance of the metal sheet 7 and the hook 95 being buckled. In this embodiment, the socket electrical connector 100 includes a plurality of metal sheets 7, and a plurality of metal sheets 7 of separate components are used as an example. Each metal sheet 7 is disposed on the insulating body 1, and each metal sheet 7 includes a hook structure 71 protruding from both sides of the tongue 12, and a plurality of through holes 72 adjacent to each hook structure 71.

[0115] The plurality of metal sheets 7 is not limited thereto. In some embodiments, the plurality of metal sheets 7 may be an integrated structure, that is, a single metal sheet 7 structure (such as Fig.14 As shown in FIG. 1 , a single metal sheet 7 is used as an example. The metal sheet 7 is disposed on the insulating body 1 . Two sides of the metal sheet 7 include hook structures 71 protruding from two sides of the tongue 12 , and a plurality of through holes 72 adjacent to each hook structure 71 .

[0116] Take a single metal sheet 7 as an example. The metal sheet 7 is located between the first flat terminal 2 and the second flat terminal 3. The metal sheet 7 is formed on the insulating body 1 and between the plurality of first contact sections 24 and the plurality of second contact sections 34. The metal sheet 7 is lengthened and widened so that the front end of the metal sheet 7 is adjacent to the front side of the tongue 12. The two sides of the front end of the metal sheet 7 protrude at the two sides of the tongue 12 to provide contact for the plug electrical connector 100. Moreover, the metal sheet 7 is arranged on the tongue 12 to enhance the strength and shielding effect of the tongue 12. In other words, the role of the metal sheet 7 is to improve the problem of crosstalk signal interference by isolating the metal sheet 7 when the plurality of first contact sections 24 and the plurality of second contact sections 34 are transmitting signals. At the same time, the metal sheet 7 can be located on the tongue 12 to enhance the structural strength of the tongue 12 itself.

[0117] In this embodiment, a plurality of hook structures 71 are formed on the outside of each metal sheet 7, and each hook structure 71 protrudes from both sides of the front end of the tongue 12. When the plug electrical connector 9 is plugged into the inside of the socket electrical connector 100, the hooks 95 on both sides of the plug electrical connector 9 will respectively lock the hook structures 71, so as to prevent the hooks 95 on both sides of the plug electrical connector 9 from rubbing against both sides of the tongue 12 and causing wear of the tongue 12.

[0118] In this embodiment, the fixing block 15 protrudes outwards with a plurality of stoppers 151 clamped on both sides of each socket terminal 200, and a positioning groove is formed between each stopper 151 for positioning the socket terminal 200. In addition, part of the plurality of stoppers 151 can be disposed in each through hole 72.

[0119] 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 increasing the area of ​​the plastic molding in the expansion portion 721. In addition, further, a plurality of stoppers 151 are respectively located at the through hole 72 and the expansion portion 721 (such as Figure 5 As shown in FIG. 1 ), a plurality of stoppers 151 are clamped on both sides of the front end of each socket terminal 200 .

[0120] In this embodiment, the metal sheet 7 has extension sections 74 and welding pins 75 extending outwardly from both sides, and the fixing block 15 has a plurality of stoppers 151 protruding outwardly and clamped on both sides of each extension section 74, so as to increase the position limit of different parts of the plurality of socket terminals 200 and increase the stability of the plurality of socket terminals 200 on the fixing block 15. In addition, the welding pins 75 pass through the rear of the base 11 and are welded to the circuit board, so that the metal sheet 7 is grounded and conductive.

[0121] In the present embodiment, each metal sheet 7 is formed with a contact arm 711 on the outside of each through hole 72, and a snap-fitting recess 712 is formed on the outer side of the contact arm 711. When the plug electrical connector 9 is inserted into the inside of the socket electrical connector 100, the hooks 95 on both sides of the plug electrical connector 9 will snap into the multiple snap-fitting recesses 712. When plugging and unplugging, 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.

[0122] In other words, after each metal sheet 7 is provided with each through hole 72, the hook structure 71 forms a hollow elastic structure. When the plug electrical connector 9 is mated 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 arms 711 of the hook structure 71 elastically swing toward the inside of the through hole 72, thereby preventing the hooks 95 on both sides of the plug electrical connector 9 from interfering with the hook structure 71 when the plug electrical connector 9 is mated with the socket electrical connector 100, causing wear of the hooks 95 on both sides of the plug electrical connector 9, which may cause structural damage and poor contact.
