In the conventional rotary positioning radio frequency coaxial connector, the shells are usually formed by injection molding of high polymer materials, and the two shells are positioned by virtue of elastic matching of the grooves and the ribs when rotating. Although this material has better self-lubricity and elasticity than metallic materials, it has advantages in terms of life and wear resistance over the outer shell of metallic materials. It still has disadvantages: the hand feeling force of the rotary positioning is insufficient, and the rotary positioning effect is not obvious particularly after the rotary positioning is used for a certain number of times; the holes of the shell passing through the cable do not take cable protection measures, and the cable is easily damaged by the edges of the shell in the use process; a smaller housing bend radius than the minimum bend radius of the cable is also one of the causes of cable damage; the two shells are riveted through rivets made of metal materials, and the rivets are easy to loosen or lead to the opening and failure of the rivet holes of the shells after the shells work for a period of time due to different materials. Today, there are also metal-shell rotationally fixed rf coaxial connectors on the market, but this structure cannot be rotationally fixed by means of elastic deformation of the metal shell, so an intermediate mechanism with better elasticity and wear-resistant material design is needed to achieve this, the intermediate mechanism of rotationally fixed rf coaxial connectors of this structure is complex in structure, and the cable is severely twisted by bending in a narrow space, resulting in easy damage of the cable.
