All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

In the description of the present invention, it should be noted that, if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings or the orientations or positional relationships that the products of the present invention are usually placed in when used, the terms are only used for convenience of describing the present invention and simplifying the description, and do not indicate or imply that the devices or elements indicated must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. Furthermore, the appearances of the terms "first," "second," and the like in the description of the present invention are only used for distinguishing between the descriptions and are not intended to indicate or imply relative importance.

Furthermore, the terms "horizontal", "vertical" and the like when used in the description of the present invention do not require that the components be absolutely horizontal or overhanging, but may be slightly inclined. For example, "horizontal" merely means that the direction is more horizontal than "vertical" and does not mean that the structure must be perfectly horizontal, but may be slightly inclined.

In the description of the present invention, it should be further noted that unless otherwise explicitly stated or limited, the terms "disposed," "mounted," "connected," and "connected" should be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 5 and 6, the high-frequency jack contact includes an outer conductor and an inner conductor, the outer conductor being designed as a combination of a sleeve 14 and a spring 15, the spring being caught on an outer surface of the sleeve. The end face of the sleeve 14 is designed into a horn-shaped round hole chamfering mode instead of the traditional petal structure, and the design mode completely avoids the problem of petal breakage caused by insertion deflection when a high-frequency pin contact element existing in an outer conductor of the traditional petal structure is inserted into a high-frequency jack contact element. Meanwhile, the existence of the reed 15 ensures good contact and conductivity of the outer conductor after the high-frequency pin contact element and the high-frequency jack contact element are oppositely inserted.

The existence of the end face form of chamfering the round hole in the inner conductor 18 avoids the problem of askew pin of the pin caused by oblique insertion when the high-frequency pin contact element and the high-frequency jack contact element are inserted oppositely in the traditional two-piece symmetrical inner conductor end face structure. Meanwhile, the notch 16 and the bulge 17 ensure good contact and conductivity of the inner conductor after the high-frequency pin and the high-frequency jack are oppositely inserted.

Preferably, the notch 16 is formed from the outer surface of the inner conductor in an inclined manner in the radial direction of the inner conductor, and stops after being formed to the center of the inner conductor and then is formed for a distance in the axial direction of the inner conductor.

As shown in fig. 12, the tail accessory 20 and the tail clip 21 are mounted at the tail of the multi-core plug connector 19, so that the stress on the welding point of the high-frequency contact element during bending and pulling of the cable assembly can be reduced, the welding point can be protected, and the reliability of high-frequency signal transmission can be improved.
