The first surrounding groove 1131 is surrounded circumferentially by the wall of the first housing 11, and the first open groove 1132 communicates with the receiving slot 101. Those skilled in the art will understand that by setting the center of the first terminal module receiving groove 113 to be surrounded circumferentially by the wall of the first housing 11, on the one hand, the conductive terminals located in the first terminal module receiving groove 113 can be better shielded; on the other hand, adjacent first terminal module receiving grooves 113 can be better separated, thereby reducing signal crosstalk.

The first end portion 3102 of the first conductive terminal 31 can be received in the first slot 211 when the first elastic contact arm 310 undergoes elastic deformation. In the embodiment illustrated in this utility model, the length of the first end portion 3102 is relatively short to improve resonance and enhance the quality of signal transmission.

[0115] In the embodiment illustrated in this utility model, the plurality of first conductive terminals 31 are divided into several groups, and each group of first conductive terminals 31 includes a first signal terminal S1 and a second signal terminal S2 adjacent to the first signal terminal S1. Preferably, the first signal terminal S1 and the second signal terminal S2 in each group of first conductive terminals 31 form a differential pair to improve signal transmission speed and is suitable for high-speed signal transmission.

[0116] In the embodiment illustrated in this utility model, the socket connector 100 further includes a first retaining block 33 fixed to the first signal terminal S1 and the second signal terminal S2 of each set of first conductive terminals 31. In one embodiment of this utility model, the first signal terminal S1 and the second signal terminal S2 are embedded in the first retaining block 33 to form an integral first terminal module 31a. The first contact portion 3101 of the first signal terminal S1 and the second signal terminal S2 in each first terminal module 31a abuts against the first signal contact piece 3041 of the mating module 300.

The first tail portion 313 extends rearward into the first mounting groove 1116 to facilitate connection with the first cable 51.

[0118] Similarly, each second conductive terminal 32 includes a second fixing portion 321 extending along the first direction A1-A1, a second resilient contact arm 320 extending forward from the front end of the second fixing portion 321, and a second tail portion 323 extending rearward from the rear end of the second fixing portion 321.

In the embodiment illustrated in this utility model, the length of the second end portion 3202 is shorter to improve resonance and enhance the quality of signal transmission. In addition, by providing the slider 81, the risk of the first end portion 3102 and the second end portion 3202 being easily damaged by foreign objects after their length is shortened is reduced, thereby improving reliability.

[0119] Please combine Figure 32As shown in the illustrated embodiment of this utility model, after the lengths of the first end portion 3102 and the second end portion 3202 are shortened, the distance T1 between the lower pointed corner of the first end portion 3102 and the upper pointed corner of the second end portion 3202 along the second direction A2-A2 is less than the thickness T2 of the tongue plate of the plug connector 200 along the second direction A2-A2. Those skilled in the art will understand that this design is generally quite dangerous, because if the plug connector 200 is inserted at a slight angle, the front end face of the plug connector 200 can easily abut against the first end portion 3102 and / or the second end portion 3202 along the first direction A1-A1, thereby damaging the first end portion 3102 and / or the second end portion 3202. However, in the illustrated embodiment of this utility model, the above problem is effectively solved by setting the slider 81 (described in detail later).

In one embodiment of this utility model, the third signal terminal S3 and the fourth signal terminal S4 are embedded in the second retaining block 34 to form an integral second terminal module 32a. The second contact portion 3201 of the third signal terminal S3 and the fourth signal terminal S4 in each second terminal module 32a abuts against the second signal contact piece 3051 of the mating module 300. The second terminal module 32a is at least partially disposed (e.g., assembled in) the second terminal module receiving groove 123.

[0122] In the embodiment illustrated in this utility model, the second retaining block 34 includes a third fixing block 341 fixed to the middle of the second fixing portion 321 of the third signal terminal S3 and the fourth signal terminal S4, and a fourth fixing block 342 fixed to the rear end of the second fixing portion 321 of the third signal terminal S3 and the fourth signal terminal S4. The third fixing block 341 and the fourth fixing block 342 are installed and fixed in the second terminal module receiving groove 123, so that the second conductive terminal 32 does not short-circuit due to contact with the second housing 12. The second tail portion 323 extends rearward into the second mounting groove 1216 to facilitate connection with the second cable 52.

[0123] In the embodiment illustrated in this utility model, the terminal protection device 8 includes a slider 81 and an elastic element 82 cooperating with the slider 81.

The slider 81 is configured to abut against the first elastic contact arm 310 and the second elastic contact arm 320 when the plug connector 200 is inserted into the receiving slot 101, causing the first elastic contact arm 310 and the second elastic contact arm 320 to elastically deform in a direction away from each other, and causing the first contact portion 3101 and the second contact portion 3201 to contact the plug connector 200 to achieve an electrical connection.

[0124] In the embodiment illustrated in this utility model, the elastic element 82 includes a first compression spring 821 and a second compression spring 822.

[0125] The slider 81 includes an abutment portion 810, a first protrusion 811 connected to one end of the abutment portion 810, and a second protrusion 812 connected to the other end of the abutment portion 810.

One end of the second compression spring 822 is sleeved on the second protrusion 8121, and the other end of the second compression spring 822 abuts against the second abutting surface 1194.

[0127] In the embodiment illustrated in this utility model, the first housing 11 and the second housing 12 jointly house the first receiving groove 1191 of the first compression spring 821, the second receiving groove 1192 of the second compression spring 822, the first abutting surface 1193 exposed in the first receiving groove 1191, and the second abutting surface 1194 exposed in the second receiving groove 1192. This configuration allows the first module M1 and the second module M2 to be shared, thus saving costs.

The distance between the first flat surface 8103 and the second flat surface 8104 is less than the distance between the first guide slope 8101 and the second guide slope 8102. When the slider 81 is in the initial position, the first contact portion 3101 abuts against the first flat surface 8103, and the second contact portion 3201 abuts against the second flat surface 8104.

[0130] The abutting part 810 is provided with a third flat surface 8105 connected to the other end of the first guide slope 8101 and a fourth flat surface 8106 connected to the other end of the second guide slope 8102. The distance between the third flat surface 8105 and the fourth flat surface 8106 is greater than the distance between the first guide slope 8101 and the second guide slope 8102.

[0131] When the plug connector 200 is inserted into the receiving slot 101 and pushes the slider 81 to move, the first contact portion 3101 passes over the first guide slope 8101 and the third flat surface 8105 and then contacts the plug connector 200 to achieve an electrical connection; the second contact portion 3201 passes over the second guide slope 8102 and the fourth flat surface 8106 and then contacts the plug connector 200 to achieve an electrical connection.

[0132] In the embodiment illustrated in this utility model, the abutting part 810 includes an insulating block 8107 and a reinforcing member 8108 embedded in the insulating block 8107, and the first guiding inclined surface 8101 and the second guiding inclined surface 8102 are both provided on the insulating block 8107.

[0133] In one embodiment of this utility model, the socket connector 100 further includes at least one grounding piece 4 mounted on the housing 1. One end of the grounding piece 4 is fixed relative to the housing 1, and the grounding piece 4 includes a first grounding piece 41 and a second grounding piece 42. In the embodiment illustrated in this utility model, there are two first grounding pieces 41 made of metal; there are also two second grounding pieces 42 made of metal.

[0134] Each first grounding plate 41 is generally U-shaped and includes a first mounting plate 411, a second mounting plate 412 opposite to the first mounting plate 411, a first connecting plate 413 connecting one side of the first mounting plate 411 and one side of the second mounting plate 412, and a first extension plate 414 extending downward and rearward from the other side of the second mounting plate 412. The first mounting plate 411 has a first mounting positioning hole 4111 that mates with the first positioning post 1124.

[0135] The first connecting plate 413 is located at the front end of the receiving slot 101 along the first direction A1-A1; when the plug connector 200 is inserted, the plug connector 200 may first contact the first connecting plate 413, thereby facilitating the release of static electricity. The second mounting plate 412 is provided with a plurality of first grounding spring arms 415 arranged at intervals along the third direction A3-A3. Each set of first conductive terminals 31 has a first grounding spring arm 415 on both sides of the first elastic contact arm 310, so as to improve the shielding effect and improve the quality of signal transmission.

[0136] In one embodiment of the present invention, the first positioning post 1124 is fixed to the first mounting positioning hole 4111, thereby fixing the first mounting plate 411 to the second upper surface 1121 of the first protrusion 112.

[0137] Each second grounding plate 42 is generally U-shaped and includes a third mounting plate 421, a fourth mounting plate 422 opposite to the third mounting plate 421, a second connecting plate 423 connecting one side of the third mounting plate 421 and one side of the fourth mounting plate 422, and a second extension plate 424 extending downward and rearward from the other side of the fourth mounting plate 422. The third mounting plate 421 is provided with a second mounting positioning hole 4211 that mates with the second positioning post 1224. The second extension plate 424 is received in a second groove 1218 of the corresponding second housing 12.

[0138] The second connecting plate 423 is located at the front end of the receiving slot 101 along the first direction A1-A1; when the plug connector 200 is inserted, the plug connector 200 may first contact the second connecting plate 423, thereby facilitating the release of static electricity. The fourth mounting plate 422 is provided with a plurality of second grounding spring arms 425 arranged at intervals along the third direction A3-A3. A second grounding spring arm 425 is provided on both sides of the second elastic contact arm 320 of each group of second conductive terminals 32 to improve the shielding effect and improve the quality of signal transmission.

[0139] In one embodiment of the present invention, the second positioning post 1224 is fixed to the second mounting positioning hole 4211, thereby fixing the third mounting plate 421 to the fourth lower surface 1222 of the second protrusion 122.

[0140] In the embodiment illustrated in this utility model, the first module M1 further includes a first shielding plate 61 and a first shielding cover plate 62 mounted on the first housing 11. In one embodiment of this utility model, the first shielding plate 61 is a metal shielding plate, and the first shielding cover plate 62 is a metal shielding cover plate. The first shielding plate 61 is mounted in the first mounting groove 1110. By installing the first shielding plate 61, the downwardly open first mounting groove 1116 can be better shielded, thereby improving the shielding effect.

[0141] In the embodiment illustrated in this utility model, the second module M2 further includes a second shielding plate 63 and a second shielding cover plate 64 mounted on the second housing 12. In one embodiment of this utility model, the second shielding plate 63 is a metal shielding plate, and the second shielding cover plate 64 is a metal shielding cover plate. The second shielding plate 63 is mounted in the second mounting groove 1210. By installing the second shielding plate 63, the downwardly open second mounting groove 1216 can be better shielded, thereby improving the shielding effect.

[0142] When the plug connector 200 is not inserted into the receiving slot 101, the slider 81 is in an initial position under the restoring force of the elastic element 82, which is close to the insertion surface of the receiving slot 101.

[0143] Please combine Figures 29 to 33 As shown, in use, the plug connector 200 is at least partially inserted into the receiving slot 101. The plug connector 200 pushes the slider 81 backward. During the backward movement, the slider 81 expands the first elastic contact arm 310 and the second elastic contact arm 320 outward. Therefore, on the one hand, the plug connector 200 can be inserted into the receiving slot 101, and on the other hand, the plug connector 200 can be prevented from abutting against the first end portion 3102 and the second end portion 3202, thus avoiding damage to the conductive terminals. This configuration can improve resonance and signal transmission quality by shortening the length of the first end portion 3102 and the second end portion 3202. On the other hand, by setting the slider 81, the risk of the first end portion 3102 and the second end portion 3202 being easily damaged by foreign objects after their length is shortened is reduced, thus improving reliability.

[0144] When the plug connector 200 is inserted into the receiving slot 101 and is fully engaged, the slider 81 is pushed backward by the plug connector 200 (e.g., Figure 31As shown), at this time, the elastic element 82 is in a compressed state; when the plug connector 200 is pulled out of the receiving slot 101, the elastic element 82 resets to push the slider 81 forward to the initial state (as shown). Figure 30 (As shown).

[0145] The outer insulating shell 9 is molded over the first module M1 and the second module M2, so that the socket connector 100 forms a whole, improving structural strength. The outer insulating shell 9 is provided with a first protrusion 91 protruding to one side and a second protrusion 92 protruding to the other side. When the socket connector 100 is installed in the socket receiving slot 100a101 of the socket frame 100a1, the first protrusion 91 is inserted into the first recess 100a102, and the second protrusion 92 is inserted into the second recess 100a103. One end of the elastic member 100a3 located in the first recess 100a102 abuts against the inner side of the abutment plate 100a2, and the other end abuts against the first protrusion 91. One end of the elastic member 100a3 located in the second recess 100a103 abuts against the inner side of the abutment plate 100a2, and the other end abuts against the second protrusion 92.

[0146] By providing the elastic element 100a3, the socket connector 100 can move along the first direction A1-A1. Those skilled in the art will understand that when the socket connector 100 moves along the first direction A1-A1, the first cable 51 and the second cable 52 also move synchronously. In the embodiment illustrated in this utility model, since the socket connector 100 is a movable end, providing a movable tolerance structure on the socket connector 100 facilitates arrangement and makes it more suitable for practical applications.

The first plug wall portion 100b11, the second plug wall portion 100b12, the third plug wall portion 100b13, and the fourth plug wall portion 100b14 together form a plug receiving cavity 100b10.
