The terminology used in the description of the disclosure herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0059] In order to make the technical scheme and beneficial effects of the present disclosure more comprehensible, the present disclosure will be further described in detail below in conjunction with specific embodiments:

[0060] Please refer to Figure 1 and Figure 2 The present disclosure provides a socket 1, which comprises a socket body 10 and a base assembly 20. The base assembly 20 is inserted and assembled in the socket body 10, and the socket 1 is inserted at both ends into a high-speed cable plug (not shown in the figure) and a printed circuit board 2, respectively.

[0061] In one embodiment, the socket body 10 is provided with a mounting end 100 and a plug end 110, the mounting end 100 is provided with a placing groove 101, and the plug end 110 is provided with a plug opening 111, the plug opening 111 and the placing groove 101 are in communication with each other. The mounting end 100 is used for plug-in mounting with the printed circuit board 2, and the plug opening 111 is plugged with the high-speed cable plug.

[0062] In one embodiment, the base assembly 20 includes a front base 201, a first row of pins 202, a middle base 203, a second row of pins 204, and a rear base 205, the front base 201, the middle base 203, and the rear base 205 form a multi-layer assembly body 21. The multi-layer assembly body 21 is assembled in the placing groove 101, and the first end of the multi-layer assembly body 21 extends into the plug opening 111, so that the multi-layer assembly body 21 is assembled in the socket body 10.

[0063] Further, as shown in Figure 3 and Figure 4 , the front base 201 is provided with a first crimping surface 2010, and the first row of pins 202 is clamped on the first crimping surface 2010; the middle base 203 is provided with a first receiving surface 2030 and a second crimping surface 2031 on both sides, respectively, the first crimping surface 2010 is crimped on the first receiving surface 2030, so that the first row of pins 202 is tightly pressed between the front base 201 and the middle base 203, to prevent the first row of pins 202 from falling off; the second row of pins 204 is clamped on the second crimping surface 2031, and the rear base 205 is provided with a second receiving surface 2050, the second crimping surface 2031 is crimped on the second receiving surface 2050, so that the second row of pins 204 is tightly pressed between the middle base 203 and the rear base 205, to prevent the second row of pins 204 from falling off.

[0064] In particular, referring again to Figure 2The first elastic contact area 2020 of the first row of pins 202 and the second elastic contact area 2040 of the second row of pins 204 extend to the outside of the first end of the multi-layer assembly 21, and the first elastic contact area 2020 and the second elastic contact area 2040 are respectively located on the opposite sides of the first end of the base assembly 20, so that the multi-layer assembly 21 can be effectively and elastically plugged with the high-speed cable plug through the first elastic contact area 2020 and the second elastic contact area 2040, avoiding the situation that the high-speed cable plug is detached from the plug interface 111 when being plugged, and improving the firmness of the plug connection between the high-speed cable plug and the socket 1. At the same time, the first elastic contact area 2020 and the second elastic contact area 2040 are respectively located on the opposite sides of the first end of the base assembly 20, that is, the first elastic contact area 2020 and the second elastic contact area 2040 are separately assembled on the opposite sides of the base assembly 20. When the high-speed cable plug is plugged with the socket 1, the conductive terminals (not shown in the figure) of the high-speed cable plug elastically abut against the first elastic contact area 2020 and the second elastic contact area 2040 respectively, avoiding the mutual interference between the first elastic contact area 2020 and the second elastic contact area 2040, and effectively connecting the high-speed cable plug and the socket 1 in communication.

[0065] Further, referring again to Figure 2 The first fisheye portion 2021 of the first row of pins 202 and the second fisheye portion 2041 of the second row of pins 204 extend to the outside of the second end of the multi-layer assembly 21, and the first fisheye portion 2021 and the second fisheye portion 2041 are convexly arranged on the outside of the mounting end 100, so that the first fisheye portion 2021 and the second fisheye portion 2041 can be crimped with the corresponding crimping holes 23 of the printed circuit board 2, and the socket 1 and the printed circuit board 2 are crimped.

[0066] During assembly, the first row of pins 202 is clamped on the first crimping surface 2010, and the first crimping surface 2010 is crimped on the first receiving surface 2030, so that the first row of pins 202 is tightly pressed between the front base 201 and the middle base 203, that is, the first row of pins 202 is assembled between the front base 201 and the middle base 203. Similarly, the second row of pins 204 is clamped on the second crimping surface 2031, and the second crimping surface 2031 is crimped on the second receiving surface 2050, so that the second row of pins 204 is tightly pressed between the middle base 203 and the rear base 205, that is, the second row of pins 204 is assembled between the middle base 203 and the rear base 205. In this way, the first row of pins 202 and the second row of pins 204 are crimped and assembled on the multi-layer assembly 21, and then the base assembly 20 is assembled in the placement groove 101, realizing the plug assembly of the socket 1.

[0067] In use, since the first elastic contact area 2020 and the second elastic contact area 2040 of the second row of pins both extend to the outside of the first end of the multi-layer assembly 21, and the first elastic contact area 2020 and the second elastic contact area 2040 are respectively located on opposite sides of the first end of the multi-layer assembly 21, the plug interface 111 can be plugged with a high-speed cable, and since the first fish-eye portion 2021 and the second fish-eye portion 2041 extend to the outside of the second end of the multi-layer assembly 21, and the first fish-eye portion 2021 and the second fish-eye portion 2041 are both protruded to the outside of the mounting end 100, the first fish-eye portion 2021 and the second fish-eye portion 2041 are pressed against the printed circuit board 2, thereby enabling the high-speed cable to communicate with the printed circuit board 2 through the socket 1.

[0068] The socket 1 described above, in production, can first form the front base 201, the middle base 203, and the rear base 205, and then press-fit and assemble the first row of pins 202 and the second row of pins 204 to the front base 201 and the middle base 203 respectively to form the multi-layer assembly 21, which has good structural strength, and in the process of press-fit and assembly, since the front base 201 and the first row of pins 202, and the middle base 203 and the second row of pins 204 do not need to be integrally injection molded, the situation that the first row of pins 202 and the second row of pins 204 are deformed by pressure during the process of integrally injection molding of the mold is avoided, and the problem of high molding difficulty existing in the traditional processing method of integrally injection molding of the connector is solved.

[0069] Referring again to Figure 3 In one embodiment, a first mounting groove 20100 is formed on the first press-fit surface 2010, and the first curved area 2022 of the first row of pins 202 is inserted into the first mounting groove 20100 to avoid the first row of pins 202 from being offset on the first press-fit surface 2010, so that the first row of pins 202 is more stable on the first press-fit surface 2010, and ensures that the first row of pins 202 is accurately assembled and pressed between the front base 201 and the middle base 203.

[0070] Referring again to Figure 5 , Figure 6 and Figure 7In one of the embodiments, the socket body 10 comprises a socket body 120 and a cover plate 130, the mounting end 100 and the plug-in end 110 are arranged on the socket body 120, the mounting end 100 is further provided with a cover setting opening 102 which is in communication with the placing groove 101, and the cover plate 130 is arranged at the cover setting opening 102 and abuts against one side of the rear base 205 which is away from the middle base 203, so as to press and fix the base assembly 20 in the placing groove 101, i.e. to press and limit the base assembly 20, to avoid the unstable situation of the multi-layer assembly 21 assembled in the placing groove 101, so as to better fix the base assembly 20 on the placing groove 101. In this embodiment, the cover plate 130 is arranged at the cover setting opening 102, so that the cover plate 130 is closed in the cover setting opening 102 and better protects the multi-layer assembly 21.

[0071] Specifically, one side of the socket body 120 which is away from the plug-in end 110 is provided with at least two connecting holes 1206, and the cover plate 130 is screwed with the connecting holes 1206 through the first threaded connecting piece 4, so that the cover plate 130 can be detachably assembled on the socket body 120; when the base assembly 20 is damaged, the cover plate 130 can be detached for maintenance or replacement of the base assembly 20.

[0072] Further, one side of the cover plate 130 which is adjacent to the placing groove 101 is provided with an elastic convex glue layer (not shown in the figure), which elastically abuts against the rear base 205, so that the cover plate 130 is tightly pressed against the rear base 205, and has better compatibility for assembly of base assemblies 20 of different sizes and models, i.e. can adapt to assembly of base assemblies 20 of more different sizes and models, to improve the adaptability of the socket body 10, to prevent the base assembly 20 from loosening after the high-speed cable is plugged in and out of the plug-in end 110 for many times, so that the plug-in end 110 is tightly plugged with the high-speed cable, and the high-speed cable and the printed circuit board 2 can interact with data.

[0073] In one of the embodiments, again referring to Figure 2, the plug-in end 110 is provided with a first anti-loosening guide hole 112 and a second anti-loosening guide hole 113, both of which are in communication with the placement groove 101; the first pin row 202 is inserted through the first anti-loosening guide hole 112, so that part of the first pin row 202 is exposed outside the plug-in end 110; the second pin row 204 is inserted through the second anti-loosening guide hole 113, so that part of the second pin row 204 is exposed outside the plug-in end 110. Thus, when the high-speed cable plug is inserted into the socket 1, the conductive terminals of the high-speed cable plug are in elastic contact with the first and second elastic contact areas 2020 and 2040 respectively, and since the first and second fish-eye portions 2021 and 2041 are in pressure contact with the printed circuit board 2, the high-speed cable can interact with the printed circuit board 2 through the first and second elastic contact areas 2020 and 2040.
