The connection slot 11 can be formed between one conductive elastic arm 12 and another supporting structure; or, as shown in FIGS. 2-3 and 5-9, the connection slot 11 is formed between two conductive elastic arms 12, and the two conductive elastic arms 12 apply a symmetrical clamping force to the second inner conductor 20, thereby improving the tightness of the mechanical connection between the second inner conductor 20 and the first inner conductor 10 and the reliability of current transmission.

Furthermore, the sheath 50 includes a sheath cavity 51. As shown in FIG. 1 and FIG. 11-12, the outer conductor 30 includes a transverse portion 31 and a vertical portion 32 distributed along the longitudinal direction of the sheath 50.

In one embodiment, the RF connector includes a pressing body 60, which is installed on the sheath 50. After the RF connector is docked with other conductive structures, the two are locked together. The operator can provide a pressing force by pressing the pressing body 60 to disengage the locking structure, thereby unlocking the RF connector and the conductive structure, making it easier for the RF connector to be separated from other conductive structures after docking.

Due to the limitation of the installation environment, especially the relatively small installation space of the RF connector in the car, the overall size of the RF connector is usually relatively small, which makes it difficult to press the operation when unlocking. The inventor has made further improvements to the RF connector: as shown in Figures 13-14, the pressing body 60 can move along the longitudinal direction of the sheath 50. The pressing body 60 shown in Figure 13 is in the working position, the pressing body 60 extends into the sheath 50, and is all located on the front side of the outer conductor 30, which will not interfere with the rotation of the outer conductor 30, and can ensure that the second inner conductor 20, the cable 43 and the outer conductor 30 can achieve 360° rotation, which is convenient for flexible adjustment of the RF connector during automobile assembly, meets the requirements of automated production, is conducive to reducing manufacturing costs, and reduces the overall longitudinal size of the RF connector. The pressing body 60 moves backward along the longitudinal direction of the sheath 50 to the unlocking position shown in Figure 14. At this time, the pressing body 60 is relatively far away from the conductive structure docking with the RF connector, and the lever arm of the pressing is lengthened, so that the force required for unlocking is small, which is convenient for unlocking.

When the pressing body 60 is in the working position, the second clamping structure 72 on the pressing body 60 is clamped with the first clamping structure 71 close to the front side, so that the position of the pressing body 60 on the sheath 50 remains stable, avoiding interference with the rotation of the outer conductor 30; when the pressing body 60 is in the unlocking position, the second clamping structure 72 on the pressing body 60 is clamped with the first clamping structure 71 close to the front side, so that the position of the pressing body 60 on the sheath 50 remains stable, avoiding interference with the rotation of the outer conductor 30; when the pressing body 60 is in the unlocking position, the second clamping structure 72 on the pressing body 60 is clamped with the first clamping structure 71 close to the front side, The structure 72 is engaged with the first engaging structure 71 close to the rear side, so as to facilitate pressing the pressing body 60 to achieve unlocking.

As shown in Fig. 15 to Fig. 17, the first clamping structure 71 includes a clamping protrusion column 711, and the second clamping structure 72 includes a clamping groove 721. By pushing the pressing body 60 along the longitudinal direction of the sheath 50, the pressing body 60 is squeezed, so that the clamping protrusion column 711 can be driven into the clamping groove 721. The clamping protrusion column 711 can be pushed out of the clamping groove 721 by pushing the pressing body 60 in the reverse direction or continuing. Preferably, the clamping protrusion column 711 extends along the radial direction of the sheath cavity 51, and the cross-section of the clamping protrusion column 711 is semicircular and the central angle is less than 180 degrees. In another embodiment, the first clamping structure 71 includes a clamping groove 721, and the second clamping structure 72 includes a clamping protrusion column 711 adapted to the clamping groove 721. The first clamping structure 71 and the second clamping structure 72 can also adopt other clamping structures.

The sheath 50 is provided with a pressing slot 52, and the pressing body 60 is provided with a shoulder body 61, which is provided in the pressing slot 52 and can move in the longitudinal direction of the sheath 50 in the pressing slot 52, and the shoulder body 61 and the pressing slot 52 play a guiding role to guide the pressing body 60 to move in the longitudinal direction of the sheath 50. The vertical height of the pressing slot 52 can be greater than the thickness of the shoulder body 61, so that the shoulder body 61 can move vertically in the pressing slot 52, which is convenient for the pressing body 60 to press vertically. The sheath 50 can be made by injection molding.

The pressing body 60 may be an injection molded part, and a square hole 62 may be provided on the pressing body 60 so that the pressing body 60 can be deformed when squeezed, making it easier to push the engaging protrusion 711 into the engaging groove 721 or push it out therefrom.
