Abstract

The invention provides a tail sealing accessory and a connector employing the same. The connector comprises a connector shell and the tail sealing accessory, wherein the tail sealing accessory is connected to the rear end of the connector shell and comprises a tail sleeve and a sealing element, the tail sleeve is connected onto the connector shell by a spiral connection structure arranged at the front end, and a rotation stop structure is arranged at the front end of the sealing element and is used for matching with the connector shell during circumferential rotation stop. When the tail sleeve is connected to the connector shell by the spiral connection structure, the rotation stop structure at the front end of the sealing element and the connector shell circumferentially stop rotating, thus, the sealing element and the connector shell are enabled to be circumferentially fixed and cannot rotate with the rotation of the tail sleeve, and a cable tightly wrapped by the sealing element is prevented from being twisted and damaged.

Description
