High-speed connectors are widely used in communication technology. They are a common type of connector for large communication equipment, ultra-high performance servers and supercomputers, industrial computers, high-end storage devices, etc. Their main function is to transmit high-speed differential signals, single-ended signals, large currents, etc. Existing connectors usually include an insulating body, a conductive terminal, a built-in circuit board, an insulating inner mold, a metal shell, and a cable extending backward from the metal shell. The conductive terminal is arranged on the insulating body. The conductive terminal has a contact portion located at the front end and a welding portion located at the rear end. The welding portion is welded to the front end of the built-in circuit board, and the front end of the cable is welded to the rear end of the built-in circuit board. The cable is electrically connected to the conductive terminal through the built-in circuit board. The insulating inner mold is overmolded at the welding point between the built-in circuit board and the cable. However, when the existing high-speed connector is used in a narrow space, when there is interference between the mainboard connector and the connector, it is not convenient to pull out and disassemble the high-speed connector, and it is difficult to extend into the narrow space, resulting in reduced unlocking efficiency.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figures 1 to 5 The present invention provides a technical solution: a multi-scenario unlocking device for a high-speed connector, comprising a shell body 1, a connecting rear shell 2 is installed on one side of the shell body 1, a PCB circuit board 9 is installed on the inner side of the shell body 1, the PCB circuit board 9 is connected to the connecting rear shell 2, a high-speed cable 11 is equidistantly arranged on one side of the PCB circuit board 9, a mounting slot 21 is opened on the top of the connecting rear shell 2, a mounting base plate 12 is installed on the inner side of the mounting slot 21, a spring plate 16 is fixedly connected to the top of the mounting base plate 12, and a connecting spring plate 16 is fixedly connected to one side of the spring plate 16 Plate 13, the top of the mounting base plate 12 is fixedly connected with a connecting frame 18, a No. 1 passband opening 14 is opened inside the connecting plate 13, a No. 2 passband opening 20 is opened inside the connecting plate 13, and a drawstring body 15 is arranged inside the No. 1 passband opening 14 and the No. 2 passband opening 20, and the drawstring body 15 passes through the inner side of the connecting frame 18. By pulling the drawstring body 15 outward, the mounting base plate 12, the spring plate 16 and the connecting plate 13 can be pulled outward, and the shell body 1 and the connected rear shell 2 are pulled outward by the mounting base plate 12 to be separated and disassembled from the host.

[0022] Among them, four No. 1 positioning rods 7 are symmetrically fixedly connected to one side of the rear shell 2, and the installation and fixing position of the rear shell 2 is restricted by the No. 1 positioning rods 7.

[0023] Among them, two No. 2 positioning rods 8 are symmetrically fixedly connected to one side of the connected rear shell 2, and the installation and fixing position of the connected rear shell 2 is restricted by the No. 2 positioning rods 8.

[0024] Among them, the top and the bottom of the rear shell 2 are fixedly connected with anti-skid strips 3, which improve the anti-skid effect when the rear shell 2 is disassembled and installed.

[0025] A groove 10 is provided on one side of the PCB circuit board 9 to facilitate better installation and positioning of the PCB circuit board 9 .

[0026] Among them, both sides of the mounting base plate 12 are fixedly connected with bevel chamfer blocks 17. By adding the bevel chamfer blocks 17, the assembly will be easier to enter along the bevel, so that the mounting base plate 12 and the mounting slot 21 are easy to install and difficult to remove, and the overall stability of the high-speed connector after extraction is increased. The mounting base plate 12, the spring plate 16 and the connecting plate 13 are not easy to move back during the insertion process, thereby improving the overall stability.

[0027] Among them, two mounting blocks 5 are symmetrically fixedly connected to the top of the spring plate 16, and two bayonet holes 4 that cooperate with the mounting blocks 5 are symmetrically opened inside the connecting rear shell 2. The installation position between the spring plate 16 and the connecting rear shell 2 is restricted by the cooperation between the mounting blocks 5 and the bayonet holes 4, so that the shell body 1, the connecting rear shell 2 and the spring plate 16 are installed and fixed more stably.

[0028] Among them, guide plates 19 are equidistantly arranged on the outer side of the PCB circuit board 9, and data connection and transmission processing is performed on the PCB circuit board 9 through the guide plates 19.

[0029] Among them, an electrical contact head 6 is provided on one side connected to the rear shell 2, and the electrical contact head 6 is connected to the guide plate 19. Through the cooperation between the guide plate 19 and the electrical contact head 6, the PCB circuit board 9 is better powered and data is transmitted.

[0030] Specifically, when in use, when a motherboard with sufficient space is used, there is no interference between the motherboard connector and the high-speed connector, and there is enough space. When there is enough space, the connector can be placed in the motherboard by pinching the connector with fingers. In this way, the connecting plate 13, the spring plate 16 and the mounting base plate 12 can be directly pressed to install the connector into the motherboard for plugging and unplugging. When the installation and use space is small, the pull belt body 15 passes through the connecting frame 18, the No. 2 passband port 20 and the No. 1 passband port 14 to connect and fix the mounting base plate 12 and the connecting plate 13. By pulling the pull belt body 15 outward, the mounting base plate 12, the spring plate 16 and the connecting plate 13 can be pulled outward. Through the restriction of the bevel chamfer block 17, the mounting base plate 12 and the mounting slot 21 are easy to install and difficult to pull out, which increases the stability of the high-speed connector after extraction. The mounting base plate 12, the spring plate 16 and the connecting plate 13 are not easy to retreat during the insertion process, which improves the overall stability. The shell body 1 and the connected rear shell 2 are pulled outward by the mounting base plate 12 to be separated and disassembled from the host.
