[0066] ​The present disclosure relates to a bend type connection plug. In one embodiment, the bend type connection plug comprises a plug base and a plug signal assembly, the plug base is provided with a first mounting slot; the plug signal assembly is arranged in the first mounting slot, the plug signal assembly comprises a plug differential joint, a ground shield joint and a shield sheet, the ground shield joint and the shield sheet are connected with the inner wall of the first mounting slot respectively, the plug differential joint is located between the ground shield joint and the shield sheet, and the plug differential joint is connected with the ground shield joint and the shield sheet respectively; wherein the plug differential joint is used for being electrically connected with the differential signal end of the first PCB and the plug differential joint of the straight type connection socket respectively, and a bending inclined angle is formed between the two ends of the plug differential joint; the two ends of the ground shield joint correspond to the two ends of the plug differential joint, and the ground shield joint is used for being electrically connected with the ground end of the first PCB and the plug ground sheet of the straight type connection socket respectively. In the bend type connection plug, the ground shield joint and the shield sheet are respectively arranged on the two sides of the plug differential joint, so that the plug differential joint is located between the ground shield joint and the shield sheet, and the plug differential joint is shielded in all directions by the shielding effect of the ground shield joint and the shield sheet, thereby effectively reducing the interference between the differential signals in the plug.

[0067] Please refer to Figure 1 which is a structural schematic diagram of the bend type connection plug of one embodiment of the present disclosure.

[0068] The bend type connection plug of one embodiment, please refer to Figure 2 , the bend type connection plug 1 comprises a plug base 11 and a plug signal assembly 12. Please refer to Figure 3 , the plug base 11 is provided with a first mounting slot 111. The plug signal assembly 12 is arranged in the first mounting slot 111, please refer to Figure 4 , the plug signal assembly 12 comprises a plug differential joint 121, a ground shield joint 122 and a shield sheet 123. The ground shield joint 122 and the shield sheet 123 are connected with the inner wall of the first mounting slot 111 respectively, the plug differential joint 121 is located between the ground shield joint 122 and the shield sheet 123, and the plug differential joint 121 is connected with the ground shield joint 122 and the shield sheet 123 respectively. Wherein, the plug differential joint 121 is used for being electrically connected with the differential signal end of the first PCB and the plug differential joint of the straight type connection socket respectively, and a bending inclined angle is formed between the two ends of the plug differential joint 121. The two ends of the ground shield joint 122 correspond to the two ends of the plug differential joint 121, and the ground shield joint 122 is used for being electrically connected with the ground end of the first PCB and the plug ground sheet of the straight type connection socket respectively.

[0069] In the present embodiment, in the curved connection plug 1, the ground shielding joint 122 and the shielding sheet 123 are respectively arranged on both sides of the plug differential joint 121, so that the plug differential joint 121 is located between the ground shielding joint 122 and the shielding sheet 123. The shielding effect of the ground shielding joint 122 and the shielding sheet 123 facilitates the omnidirectional shielding of the plug differential joint 121, and effectively reduces the interference between the differential signals inside the plug.

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

[0071] In one of the embodiments, the bending inclination angle is 60° to 120°. In the present embodiment, the plug differential joint 121 has a bending structure, and the distribution position of the plug differential joint 121 on the plug base 11 has a bending direction, so that the two ends of the plug differential joint 121 are not on the same straight line, thereby enabling the two ends of the plug differential joint 121 to be connected to two PCBs arranged in a non-parallel manner. By adjusting the bending inclination angle of the plug differential joint 121, the two PCBs arranged in different poses can be adapted.

[0072] In another embodiment, as shown in Figure 4 , the two ends of the plug differential joint 121 are arranged perpendicular to each other. Since the two ends of the plug differential joint 121 are respectively electrically connected to the differential signal end of the first PCB and the socket differential joint of the straight connection socket, the straight connection socket is connected to the second PCB. In the case that the two ends of the plug differential joint 121 remain perpendicular, the first PCB and the second PCB can remain in a perpendicular state, thereby facilitating the arrangement of a connector at the perpendicular angle of the two PCBs to achieve high-speed transmission of differential signals.

[0073] In one of the embodiments, as shown in Figure 5 , the plug differential joint 121 includes a first insulating base 1212 and at least one plug differential signal pin 1211. Each plug differential signal pin 1211 is connected to the first insulating base 1212. The plug differential signal pin 1211 is respectively electrically connected to the differential signal end of the first PCB and the socket differential joint of the straight connection socket. The first insulating base 1212 is respectively connected to the ground shielding joint 122 and the shielding sheet 123. In the present embodiment, the first insulating base 1212 serves as a mounting base for the plug differential signal pin 1211. The first insulating base 1212 also insulates and protects the plug differential signal pin from the ground shielding joint 122 and the shielding sheet 123 to avoid signal crosstalk.

[0074] In another embodiment, as shown inFigure 6 Each of the plug differential signal pins 1211 includes two oppositely arranged plug differential signal pins 12111, and the two plug differential signal pins 12111 have a 90° bending structure, facilitating the plug differential signal pins 12111 to electrically conduct the differential signal ends on the PCBs placed in two different directions. The width of the plug differential signal pins 12111 at the bending position is less 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 of the plug differential signal pins 12111 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 at the bending position 1000 inside the bending is less than the length of the other plug differential signal pin 12111 at the bending position 1001 outside the bending, that is, in the plug differential signal pin pair, the length of the plug differential signal pin 12111 at the bending position 1000 on the bending inward side is less than the length of the plug differential signal pin 12111 at the bending position 1001 on the bending outward side, so that the differential signal transmission delay between the two plug differential signal pins in the plug differential signal pin pair is consistent, thereby effectively reducing the internal delay difference of the plug differential signal pin pair.

[0075] In another embodiment, the first insulating base 1212 is injection molded with the plug differential signal pin pair 1211, specifically, the middle part of the plug differential signal pin pair 1211 is injection molded with the first insulating base 1212, and the two ends of the plug differential signal pin pair 1211 are exposed for electrical connection with the differential signal ends of the first PCB and the plug differential assembly of the straight plug socket.
