Connector accessory with shielding and sealing structure

The utility model synthesizes the performance characteristics of various connector accessories. An electric connection point which connects the shielding layer of a cable with the accessory is arranged at the tail of a sleeve to enlarge the inner space of the accessory, the shield of the cable is tightly pressed on the shell to guarantee the reliable connection after a sealing glue sheath is forced to deform, and a sealing rubber ring is tightly extruded at the end face at the tail of the sleeve and is tightly pressed on the wall of the inner hole of a screw nut and a leather sheath out of the cable, so that the sleeve is internally formed into a sealed inner cavity, therefore, the connector accessory realizes the 360 degrees shielding and the omni-directional sealing, effectively overcomes the defects of the existing cable accessory such as complex structure, large volume, inconvenient installation and the like, and solves the problems that various performance requirements are hard to unify such as the shielding, the sealing, the pull-off resisting and the like. The connector accessory with the shielding and sealing structure is attractive and streamline in appearance, simple in structure, small in volume, fast and convenient for installation and connection, and high in environment resistance.
