In order to facilitate understanding of the above-described technical aspects of the present invention, the above-described technical aspects of the present invention will be described in detail below in terms of specific usage.

The high-frequency connector comprises a socket 1 and a plug, wherein the socket 1 comprises a shell, a U-shaped magnet 2, a D-shaped matching port 3, a coaxial terminal 4 and the like.

The D-shaped matching port is used for forming a trapezoidal butt joint surface, so that reverse insertion and misplugging are avoided; the socket 1 is used with the plug cooperation, and the structure of plug is: the plug is provided with the trapezoidal inner sleeve, the trapezoidal inner sleeve is matched with the D-shaped matching port, and the D-shaped matching port is accurately positioned, so that the socket 1 and the plug can be vertically inserted and separated when being plugged and unplugged, the pins and the jacks cannot be damaged, and the service life of a product is ensured.

The upper bottom edge and the lower bottom edge of the D-shaped matching port are respectively provided with a guide groove 7, the guide grooves 7 protrude towards the inside of the D-shaped matching port, and the two guide grooves 7 are oppositely arranged. The plug is provided with a trapezoidal inner sleeve, the upper bottom edge and the lower bottom edge of the trapezoidal inner sleeve are respectively provided with an arc-shaped groove, and the guide groove 7 is matched with the arc-shaped grooves. Therefore, the socket 1 and the plug can be accurately positioned, and the socket 1 and the plug can be vertically inserted and separated when plugged. Since the guide groove 7 is in line contact with the arc-shaped groove at this time, it is possible to reduce frictional resistance when pushing in and pulling out the plug, making it easier to handle.

Since the magnetic poles of the two U-shaped magnets 2 are in a different state, a dense magnetic line distribution is formed at the adjacent position of the two U-shaped magnets 2, so that the magnetic flux flowing through the coaxial terminal 4 can be restricted, and a weak magnetic region 6 and a strong magnetic region 5 having a large difference in magnetic field strength can be formed on the housing. By arranging the coaxial terminal 4 in the weak magnetic region 6, it is possible to prevent dense magnetic lines of force from flowing therethrough, thereby reducing the interference of the magnetic field. Therefore, when the high frequency connector performs signal transmission, i.e. the contact pin and the coaxial terminal 4 are electrically connected, since the coaxial terminal 4 is disposed in the weak magnetic region 6 with weaker magnetic field strength, the electromagnetic interference can be limited, and the interference of the electromagnetic field on the signal transmission can be reduced and the signal transmission performance can be improved.
