The ground shield assembly 122 and the shielding sheet 123 are respectively connected to the inner wall of the first mounting groove 111, the plug differential assembly 121 is located between the ground shield assembly 122 and the shielding sheet 123, and the plug differential assembly 121 is respectively connected to the ground shield assembly 122 and the shielding sheet 123. Among them, the plug differential assembly 121 is used to be electrically connected to the differential signal end of the first PCB board and the socket differential assembly of the straight connection socket, respectively, and a bending inclination angle is formed between the two ends of the plug differential assembly 121. The two ends of the ground shield assembly 122 correspond to the two ends of the plug differential assembly 121, and the ground shield assembly 122 is used to be electrically connected to the ground end of the first PCB board and the socket grounding sheet of the straight connection socket, respectively.

[0069] In this embodiment, in the bent connecting plug 1, a grounding shielding assembly 122 and a shielding plate 123 are respectively installed on both sides of the plug differential assembly 121, so that the plug differential assembly 121 is located between the grounding shielding assembly 122 and the shielding plate 123. Through the shielding effect of the grounding shielding assembly 122 and the shielding plate 123, it is easy to achieve all-round shielding of the plug differential assembly 121, and effectively reduce the interference between the differential signals inside the plug.

[0070] In another embodiment, the plug base is a plastic head base.

[0071] In one embodiment, the bending angle is 60° to 120°. In this embodiment, the plug differential assembly 121 has a bending structure, and the distribution position of the plug differential assembly 121 on the plug base 11 has a bending direction, so that the two ends of the plug differential assembly 121 are not in the same straight line, so that the two ends of the plug differential assembly 121 can be connected to two PCB boards that are not arranged in parallel. By adjusting the bending angle of the plug differential assembly 121, it is convenient to transfer two PCB boards with different placement postures.

[0072] In another embodiment, see Figure 4 The two ends of the plug differential assembly 121 are arranged perpendicularly to each other. Since the two ends of the plug differential assembly 121 are electrically connected to the differential signal end of the first PCB board and the socket differential assembly of the straight connection socket respectively, and the straight connection socket is connected to the second PCB board, when the two ends of the plug differential assembly 121 remain vertical, the first PCB board and the second PCB board can be kept in a vertical state, which is convenient for arranging a connector at the vertical angle of the two PCB boards to realize high-speed transmission of differential signals.

[0073] In one embodiment, see Figure 5 , the plug differential assembly 121 includes a first insulating base 1212 and at least one plug differential signal pin 1211, each of the plug differential signal pins 1211 is connected to the first insulating base 1212, the plug differential signal pins 1211 are electrically connected to the differential signal end of the first PCB board and the socket differential assembly of the straight connection socket, and the first insulating base 1212 is respectively connected to the ground shield assembly 122 and the shielding sheet 123.

[0074] In another embodiment, see Figure 6 Each of the plug differential signal pins 1211 includes two oppositely disposed plug differential signal pins 12111, and the two plug differential signal pins 12111 have a 90° bending structure, so that the plug differential signal pins 12111 can electrically connect the differential signal ends on two PCBs placed in different directions. The width of the plug differential signal pins 12111 at the bending position is smaller than the width of the plug differential signal pins 12111 at the non-bending position, so that the impedance of the plug differential signal pins 12111 at the bending position is consistent with the impedance at the non-bending position, effectively improving the impedance mismatch phenomenon of the plug differential signal pins. The length of one of the plug differential signal pins 12111 on the inner side of the bend at the bending position 1000 is smaller than the length of one of the plug differential signal pins 12111 on the outer side of the bend at the bending position 1001, that is, in the plug differential signal pin pair, the length of the bending position 1000 of the plug differential signal pin 12111 on the inner side of the bend is smaller than the length of the bending position 1001 of the plug differential signal pin 12111 on the outer side of the bend, so that the differential signal transmission delay between the two plug differential signal pins in the plug differential signal pin pair remains consistent, thereby effectively reducing the internal delay difference of the plug differential signal pin pair.

[0075] In another embodiment, the first insulating base 1212 and the plug differential signal pin 1211 are injection molded.

Specifically, the second positioning structure 12122 is a positioning square cavity, and the positioning square cavity is disposed on the first insulating base 1212, and the positioning square cavity is aligned with the installation position of the ground shield assembly 122, that is, part of the ground shield assembly 122 is clamped in the positioning square cavity, so that the ground shield assembly 122 is clamped with the first insulating base 1212, so as to improve the connection stability between the ground shield assembly 122 and the first insulating base 1212.

[0078] Furthermore, the plug differential assembly 121 further includes at least one hook structure 12123 disposed on the first insulating base 1212, the plug base 11 is provided with at least one cantilever square cavity 113, and each hook structure 12123 is clamped in one of the cantilever square cavity 113. In this embodiment, the hook structure 12123 is protrudingly disposed on the first insulating base 1212, and the protruding direction of the hook structure 12123 faces the cantilever square cavity 113. When the plug differential assembly 121 is installed in the first installation groove 111 of the plug base 11, part of the hook structure 12123 is clamped in the cantilever square cavity 113, so that the hook structure 12123 and the plug base 11 are embedded, so as to improve the installation stability of the plug differential assembly 121 on the plug base 11.

[0079] In another embodiment, at least two of the hook structures 12123 are arranged opposite to each other, and the distribution direction of at least two of the hook structures 12123 is perpendicular to the notch direction of the first installation slot 111. In this embodiment, the hook structures 12123 are symmetrically arranged and distributed, and the distribution direction of the hook structures 12123 is perpendicular to the notch direction of the first installation slot 111, so as to facilitate the clamping in the upper and lower directions of the first installation slot 111, thereby facilitating the plug base 11 to provide two clamping forces perpendicular to the installation direction of the plug differential assembly 121, and effectively improving the installation stability of the plug differential assembly 121.
