Low frequency electric connector shielding afterbody clamping structure

The utility model relates to an electrical apparatus connecting device especially relates to low frequency electric connector shielding afterbody clamping structure, including nut, straight tube or return bend, line ball claw, tail nut and sheath. The one end of straight tube or return bend is located through the jump ring cover to the nut, and the other end of straight tube or return bend is located to line ball claw cover, and it is outside that the line ball claw is located to tail nut cover, on straight tube or return bend are located to the sheath cover, and wraps up the tail nut. The one end that the line ball claw is close to straight tube or return bend be the line ball cover, and the line ball cover is the round platform column structure, and the radial concave-convex structure in groove is split for the axial to the line ball claw other end, and the position that straight tube or return bend surface correspond the line ball cover has the inclined plane, through screwing up of tail nut, the line ball cover can make shielding layer circumference 360 evenly compress tightly with the inclined plane of straight tube or return bend, the line ball claw other end is radial evenly to be contract to the processing is shielded from straight tube or return bend outside to the shielding cable to the effect that reaches fine shielding and press from both sides tight cable, this mode, conveniently adjusts easy operation.
