[0025] The present utility model provides a high-speed connector.

[0026] As Figures 1-4 shown, the high-speed connector provided by the embodiment of the present utility model includes a plastic housing 10, a main body 20, an insulator 30 and two center pins 40 which are arranged in sequence from outside to inside. An opening 11 is provided at the front end of the plastic housing 10, and an anti-fooling limit rib 13 is provided on the inner wall surface of the plastic housing 10. An anti-fooling limit platform 23 which can be cooperatively connected with the anti-fooling limit rib 13 is provided on the outer wall surface of the main body 20.

[0027] In this embodiment, the high-speed connector includes a plastic housing 10, a main body 20, an insulator 30, and two center pins 40 arranged in sequence from outside to inside. The front end of the plastic housing 10 is provided with an opening 11, and an anti-fooling limit rib 13 is provided on the inner wall surface of the plastic housing 10. An anti-fooling limit platform 23 that can be cooperatively connected with the anti-fooling limit rib 13 is provided on the outer wall surface of the main body 20. Therefore, in this technical solution, through the cooperation of the anti-fooling limit rib 13 and the anti-fooling limit platform 23, the installation efficiency between the plastic housing 10 and the main body 20 can be rapidly improved, and the production efficiency can be enhanced. That is to say, when assembling this connector, only when the anti-fooling limit rib 13 and the anti-fooling limit platform 23 are correctly paired (i.e., when the anti-fooling limit rib 13 is aligned with the anti-fooling limit platform 23) can the connector be correctly assembled, thereby improving the installation efficiency.

[0028] In addition, an insertion groove 12 is formed on the outer wall surface of the plastic housing 10, and a card slot 24 recessed circumferentially is provided on the outer wall surface of the main body 20. The high-speed connector further includes a latch 60 that can be inserted into the card slot 24 through the insertion groove 12. In this embodiment, the latch 60 can be inserted into the card slot 24 from the outside. The latch 60 has two deformable arc-shaped arms, and the arc-shaped arms can be closely fitted on the card slot 24 under the action of extrusion force, so that both sides of the card slot 24 limit it to achieve the purpose of limiting the main body 20 through the latch 60.

[0029] The main body 20 includes a spring piece portion 21 and a connecting portion 22 connected to each other. The spring piece portion 21 is arranged in the opening 11, and both the anti-fooling limit platform 23 and the card slot 24 are arranged on the connecting portion 22.

[0030] Please refer to Figures 3-4 , a first limit groove 31 extending along its axial direction is provided on the outer end surface of the insulator 30, and a limit post 25 that can be cooperatively connected with the first limit groove 31 is provided on the inner wall surface of the connecting portion 22. The high-speed connector further includes a connecting sleeve 50, and the connecting sleeve 50 is sleeved on the end portion of the insulator 30 and is located outside the insulator 30. A second limit groove 51 communicating with the first limit groove 31 is provided on the connecting sleeve 50, and the limit post 25 can be cooperatively connected with the second limit groove 51. In this embodiment, by providing the connecting sleeve 50, the second limit groove 51 and the first limit groove 31 on the connecting sleeve 50 are combined to form a whole. When the limit post 25 is clamped in this whole, the limit post 25 can limit both of them to prevent the phenomenon of disengagement.

[0031] In addition, in order to further improve stability, an anti-retreat groove 32 is provided on the insulator 30, and an anti-retreat portion 52 is provided on the connecting sleeve 50. The anti-retreat portion 52 is snap-connected in the anti-retreat groove 32. In this embodiment, the outer shape of the anti-retreat groove 32 is the same as that of the anti-retreat portion 52. By clamping the anti-retreat portion 52 in the anti-retreat groove 32 and cooperating with the limit post 25, the first limit groove 31 and the second limit groove 51, the stability is jointly improved.

[0032] Please refer to Figures 2-3 , the high-speed connector further includes a cable 70 connected to the end of the main body 20. The cable 70 and the main body 20 are connected by injection molding encapsulation 80. In this embodiment, the outer wall surface of the main body 20 has ribs and grooves. When injection molding encapsulation 80 is used for injection molding, it forms an integral body with the ribs and grooves on the outer wall surface of the main body 20, and forms an integral body when the injection molding encapsulation 80 connects the cable 70 and the main body 20, so as to prevent axial detachment between the injection molding encapsulation 80 and the main body 20 and increase the holding force.

[0033] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the concept of the present invention by using the content of the specification and drawings of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
