Description

Technical Field

[0001] The present invention relates to the technical field of high-speed connectors, and in particular to a high-speed cable assembly and an assembly and use method thereof. Background Art

[0002] A board-type high-speed connector is a type of high-speed connector, which is usually used for high-speed transmission of data and signals, with a higher transmission rate and lower signal distortion. Board-type high-speed connectors are often used as components to connect circuit boards in electronic devices, and are usually suitable for high-speed data communications, computer networks, communication equipment, industrial control systems and other fields.

[0003] The current board-type high-speed connector generally includes a PCB board and a cable assembly. During installation, bolts or screws are usually used to fix the cable assembly to the PCB board. However, since most of its application scenarios are servers, there may be a small installation space, and it is impossible to use tools such as screwdrivers and wrenches to tighten the screws or bolts. At the same time, the current board-type high-speed connector body is becoming more and more miniaturized, and the use of screws or bolts will cause inconvenience in installation and use.

[0004] A splint-type connector structure is disclosed in the utility model with application number: CN202320599035.6 and publication number: CN220233495U, including a connector body and a PCB board. A groove is provided on the connector body, and a limit hook and a positioning protrusion are provided in the groove. A limit hole and a positioning groove are provided on one side edge of the PCB board, and the positioning protrusion can be inserted into the positioning groove, and the limit hook can slide into the limit hole and engage with the limit hole. The positioning protrusion is plugged into the positioning groove, which can play a positioning and guiding role to prevent the connector body and the PCB board from being misaligned during plugging. Bolts or screws are still required to connect the connector body to the PCB, so it still has the problem of inconvenience in installation and use when in use. Summary of the invention

[0045] The present invention sets a plurality of plug-in rods 103 at the bottom of the installation shell 10, and sets a plurality of plug-in rings 104 that cooperate with the plug-in rods 103 on the PCB board.

Then, the installation shell 10 is pressed by hand to complete the connection between the installation shell 10 and the PCB board, that is, the connection between the high-speed cable assembly and the PCB board is completed. Compared with the traditional connection method of bolts or screws, the present invention no longer needs to use auxiliary installation tools such as screwdrivers or wrenches, and is more suitable for use scenarios with smaller installation spaces and more miniaturized board-type high-speed connectors. The problem of inconvenient installation and use of board-type high-speed connectors caused by the current use scenarios of board-type high-speed connectors, which usually have smaller installation spaces and are increasingly miniaturized, is solved.

[0046] By using the structure of the high-speed cable assembly described in the present invention, the overall size of the high-speed cable assembly can be made very small, thereby making the high-speed cable assembly more suitable for servers in the prior art.

[0047] Among them, one end of the high-speed cable 50 can be fixedly connected to the terminal assembly 30 by laser welding, and the mounting shell 10 and the connector 102 are both made of metal.

[0049] When in use, the plug rod 103 at the bottom of the mounting housing 10 can be inserted into the plug ring 104 on the PCB board by pressing the rubber pad 112 and the pressing plane 109, thereby facilitating the installation of the mounting housing 10 and the PCB board. The provision of the trigger block 110 can facilitate the removal of the mounting housing 10 from the PCB board, thereby facilitating the replacement of the high-speed cable assembly.

[0050] like Figures 7 to 12 As shown, in order to facilitate making the size of the high-speed cable assembly described in the present invention smaller and to solve the problem that the current board-type connector is not suitable for installation and use in a smaller space, this embodiment is improved on the basis of the above embodiment. The difference from the above embodiment is that the terminal assembly 30 includes a plastic-encapsulated body 300, a terminal mounting block 301, a plurality of signal terminals 302 and a plurality of grounding terminals 303, and the plurality of signal terminals 302 and the plurality of grounding terminals 303 are arranged on the terminal mounting block 301, and are fixedly connected to the terminal mounting block 301 through the plastic-encapsulated body 300, and a pair of signal terminals 302 is provided between every two adjacent grounding terminals 303.

[0051] The signal terminal 302 and the ground terminal 303 are both U-shaped structures, including an integrally formed welding arm 304, a connecting arm 305 and a contact arm 306.

A mounting slot 113 is provided on one side of the mounting shell 10. One end of the two groups of high-speed cables 50 are respectively passed through the mounting slot 113 and welded to the welding arm 304.

[0052] The provision of the elastic contact arm 400 on the shielding body 40 can enable the grounding terminal 303 to form better contact with the shielding body 40 .

[0053] A plurality of first mounting grooves 307 are provided on one side of the terminal mounting block 301, and the connecting arm 305 can be snapped into the first mounting groove 307. A plurality of second mounting grooves 308 are provided on the top of the terminal mounting block 301, and the welding arm 304 can be snapped into the second mounting groove 308. A plurality of first deformation grooves 309 and a plurality of second deformation grooves 310 are provided on the bottom of the terminal mounting block 301, and a pair of second deformation grooves 310 are provided between every two adjacent first deformation grooves 309. The first deformation groove 309 is arranged in cooperation with the contact arm 306 in the grounding terminal 303, and the first deformation groove 309 is arranged in cooperation with the contact arm 306 in the grounding terminal 303. The two deformation grooves 310 are arranged in cooperation with the contact arms 306 in the signal terminal 302, wherein an opening 311 is provided at one end of the first deformation groove 309, and the elastic contact arms 400 on the shielding body 40 can extend into the first deformation groove 309.

When the contact arms 306 on the grounding terminals 303 enter the first deformation groove 309, they can contact the elastic contact arms 400 on the shielding body 40.

[0054] The provision of the first deformation groove 309 can also provide space for the deformation of the elastic contact arm 400 on the shielding body 40 .

[0055] The terminal mounting block 301 is provided with an L-shaped limiting groove 312 on one side of the first mounting groove 307. The L-shaped limiting groove 312 is located above the first mounting groove 307 and on one side of the second mounting groove 308.
