As an indispensable component in electronic devices, the connector plays a very important role in the process of 5G, 6G signal high-speed transmission.

[0003] The existing 5G, 6G signal high-speed transmission connector generally includes a socket and a plug. The socket is welded on the socket circuit board of the electronic device such as a mobile phone through the socket welding leg, and the plug is welded on the plug circuit board such as a plug circuit board with a signal processing component through the plug welding leg. When the plug and the socket are plugged together, the communication signal processed by the signal processing component is transmitted to the circuit board of the mobile phone in sequence through the plug and the socket. The reliability of the plug and the socket in the mutual plugging cooperation has an important influence on the quality of 5G, 6G signal high-speed transmission.

[0004] However, in the prior art, there is a lack of structure for locking the fixed state when the plug and the socket are mutually plugged and fixed, resulting in low reliability of the plugging cooperation, so that the plug and the socket are easy to shake or even separate from each other during the working process, causing unstable signal transmission capability and poor effect of 5G, 6G signal high-speed transmission.

[0041] Reference Figures 1 to 4 , Figure 7 and Figure 8, As one object of the present application, there is provided a reliable mating connector comprising a socket 10 and a plug 20 which are mated with each other. The socket 10 comprises a socket insulator 11 and a socket contact frame 12 arranged at both ends of the socket insulator 11, respectively. The socket contact frame 12 comprises a first socket contact portion 121 and a pair of second socket contact portions 122 arranged at opposite sides of the first socket contact portion 121, respectively. The pair of second socket contact portions 122 extend in a first direction away from the first socket contact portion 121 in parallel with each other. It is to be noted that the first direction is parallel to a length direction of the socket insulator 11 after the socket contact frame 12 is fixed to the socket insulator 11. In addition, a metal terminal of the plug 20 of the present application and a plug contact frame 22 are embedded in advance in a plug insulator 21 and then a clamping member 23 is assembled. The socket 10 further comprises a pair of first elastic contact points 12211, a pair of second elastic contact points 12221 and a pair of clamping grooves 1223 arranged at opposite sides of each of the second socket contact portions 122, respectively. In the first direction, the clamping groove 1223 of each of the second socket contact portions 122 is located between the first elastic contact point 12211 and the second elastic contact point 12221. Figure 7 、 Figure 8 As shown in FIGS. 1 and 2, the plug 20 comprises the plug insulator 21 and a plug contact frame 22 arranged at both ends of the plug insulator 21, respectively. The plug contact frame 22 comprises a first plug contact portion 221, a pair of second plug contact portions 222 arranged at opposite sides of the first plug contact portion 221, respectively, and a soldering plate 223 connected to the first plug contact portion 221. The pair of second plug contact portions 222 extend in a second direction away from the first plug contact portion 221 in parallel with each other. It is to be noted that the second direction is parallel to a direction in which both free ends of the plug insulator 21 extend toward the middle portion after the socket contact frame 12 is fixed to the socket insulator 11. The first direction is parallel to the second direction and both are perpendicular to a mating direction between the plug 20 and the socket 10. The soldering plate 223 comprises a pair of first plug soldering legs 2231 protruding away from and perpendicularly to the pair of second socket contact portions 122, respectively. The first plug soldering legs 2231 are used to solder the plug 20 to a plug circuit board, for example. In combination with Figure 4As shown, a pair of first elastic contact points 12211 and a pair of second elastic contact points 12221 clamp the plug guide frame 22 therebetween. The plug 10 further comprises a pair of clamping portions which are respectively clamped and electrically contacted with a pair of clamping grooves 1223 when the socket 10 and the plug 20 are plugged together in a fixed plugging direction, the plugging direction including a direction in which the plug 20 is plugged to the socket 10, a direction in which the socket 10 is plugged to the plug 20, and two opposite directions in which the socket 10 and the plug 20 are moved towards each other for plugging, so that the plug 20 is clamped and electrically contacted with the socket 10 at both ends. Therefore, the reliable connector of the present application can ensure that the plugging of the plug 20 and the socket 10 has high reliability by clamping and electrically contacting the clamping portions of the plug 20 with the clamping grooves 1223 of the socket 10, and the clamping portions and the clamping grooves 1223 can conduct electricity to transmit electrical signals, so that the high-speed transmission of 5G and 6G signals is good, and four electrically conductive contact effects are formed by the two pairs of four elastic contact points on the socket guide frame 12, cooperating with the two electrically conductive contact effects formed by the two clamping portions, so as to obtain six elastic contact effects, which is beneficial to the transmission of 5G and 6G electrical signals between the plug 20 and the socket 10. Moreover, by arranging the clamping grooves 1223 between the first elastic contact points 12211 and the second elastic contact points 12221, the electrically conductive contact force of each elastic contact point and the plug guide frame 22 can be enhanced when the clamping portions and the clamping grooves 1223 are clamped, ensuring the reliability and high quality of electrical signal transmission.

Therefore, the second socket guide part 122 not only has a compact overall structure, but also the first elastic contact point 12211 and the second elastic contact point 12221 have a large elastic force acting on the plug guide frame 22, which ensures the close contact between the elastic contact points and the plug guide frame 22.

[0043] Preferably, the first elastic contact point 12211 and the second elastic contact point 12221 are both provided with a first curved surface, the first elastic arm 1221 and the second elastic arm 1222 are both provided with a second curved surface at the joint with the bottom connecting plate 1227, and the curvature of the first curved surface is greater than the curvature of the second curved surface, in the plug-in direction of the plug 20 inserted into the socket 10, Figure 1 the arrow in the plug-in direction is perpendicular to the first direction and the second direction mentioned above, for each second socket guide part 122, the first elastic contact point 12211 is located upstream of the second elastic contact point 12221, and the clamping groove 1223 is arranged on the first side plate 1224 and located between the first elastic contact point 12211 and the second elastic contact point 12221 in the first direction. In this way, a pair of first elastic contact points 12211 first elastically contact the plug guide frame 22, which plays a guiding and limiting role in inserting the plug 20 into the socket 10, and a pair of second elastic contact points 12221 elastically contact the plug guide frame 22, which is conducive to guiding and fine-tuning the clamping part to accurately enter the clamping groove 1223, thereby obtaining excellent clamping and fixing and conductive contact effects.

[0044] Please refer to Figure 7 and Figure 8In the first embodiment of the plug guide frame 22, the plug guide frame 22 comprises a guide plate 224, two ends of the guide plate 224 are connected with the soldering plate 223 and the first end of the first plug guide part 221 respectively, the first end of the guide plate 224 connected with the first end of the first plug guide part 221 is provided with a guide bent plate 2241, the guide bent plate 2241 can play a role of guiding the plug guide frame 22 to be inserted into the socket guide frame 12 accurately, the second end of the guide plate 224 is bent and extends in the second direction towards the free end of the second plug guide part 222, the guide plate 224 is connected with the middle part of the soldering plate 223 perpendicularly, a pair of first plug soldering legs 2231 are arranged at two ends of the soldering plate 223 respectively, the second plug soldering leg 225 is arranged at the second end of the first plug guide part 221, preferably, the free end of the second plug soldering leg 225 is located in the same plane with the bottom surface of the soldering plate 223, the second plug soldering leg 225 is opposite to the guide plate 224 and extends along the direction perpendicular to the plane where the pair of first plug soldering legs 2231 are located, in the direction in which the second plug guide part 222 extends in the second direction, the first end and the second end of the first plug guide part 221 are opposite to each other and the first end is closer to the free end of the second plug guide part 222 than the second end. In this way, by arranging three plug soldering legs and the connecting lines of the three soldering parts forming a substantially equilateral triangle, the plug guide frame 22 can be firmly soldered and fixed so as to transmit electrical signals and ground in high quality.

[0045] Please refer to Figure 3 , Figure 5 and Figure 6 for further improvement, the plug 20 further comprises a pair of clamping members 23, the clamping member 23 comprises a clamping member body and a fixed arm 231 and a pair of elastic arms 232 bent and extended from the clamping member body, the pair of elastic arms 232 are arranged symmetrically with respect to the fixed arm 231, the clamping member body comprises a main connecting plate 233 and a pair of vertical plates 234 perpendicularly arranged with respect to the main connecting plate 233 and located at two sides of the fixed arm 231 at equal intervals, each elastic arm 232 comprises a connecting and turning plate 2321 and an elastic clamping buckle 2322 connected with a vertical plate 234 in sequence, the two elastic clamping buckles 2322 extend opposite to each other away, the elastic clamping buckle 2322 is arranged as a clamping part, the plug insulator 21 is provided with a fixed hole 211, a receiving groove 212 and a pair of recessed grooves 213, the clamping member body is arranged in the receiving groove 212, the fixed arm 231 is inserted into the fixed hole 211, and the elastic clamping buckle 2322 is movably arranged in the recessed groove 213. Figure 9 and Figure 10, as the second embodiment of the plug guide frame 22, the second end of the guide plate 224 of the plug guide frame 22 is bent to extend towards the free end of the second plug guide part 222. In this way, there is a larger gap between the guide plate 224 and the free end of the plug guide frame 22 to allow the assembly of the clamping member 23 after the metal terminals of the plug 20 and the plug guide frame 22 are pre-embedded and integrated with the plug insulator 21 by casting. The clamping member body and the first plug guide part 221 are located on both sides of the plug insulator 21, and the second plug guide part 222 includes a pair of opposite side plates, a through slot 2221 is respectively and oppositely formed on the pair of side plates, and a pair of elastic buckles 2322 respectively protrude outside the through slot 2221. During the plug-in cooperation between the socket 10 and the plug 20, as the pair of through slots 2221 and the pair of clamping grooves 1223 move from being staggered to being opposite to each other, the pair of elastic buckles 2322 correspondingly move from being close to each other to being far away from each other, so that each elastic buckle 2322 protrudes outside the recessed groove 213 and the through slot 2221 and is clamped in the clamping groove 1223.

The elastic buckle is inclined from the connecting plate 2321 to the direction away from the clamping member body, and the area of the inclined surface gradually increases. Since the area of the inclined surface gradually increases, the strength of the elastic buckle is enhanced while the elastic clamping force of the elastic buckle is increased. The two sides of the fixing arm 231 are symmetrically provided with a pair of protrusions 2311 with straight tips, the pair of protrusions 2311 are in interference fit with the fixing hole 211 and the straight tips are perpendicular to the center axis of the fixing hole 211, and the elastic buckle includes a clamping surface opposite to the top surface of the clamping groove 1223.
