| 20110163530 | TAPERED TYPE CONNECTOR FOR A FLEXIBLE TUBE - A tapered type connector for a flexible tube, comprising: a) a coupling body having an external threaded portion and a stranded portion at one side thereof, an annular cavity being formed in the external threaded portion such that the stranded portion is extended into the annular cavity, the defining wall of the annular cavity being tapered inward to form a first external fastening cone, the end portion of the flexible tube fitting over the stranded portion; b) a clamp ring having at the internal end thereof a fist internal fastening cone facing to the first external fastening cone of the coupling body and at the external end thereof a second internal fastening cone, a clamp indentation being formed axially in the clamp ring, the clamp ring slipping over the periphery of the outer end of the flexible tube; and c) a clamp nut having an internal threaded portion (corresponding to the external threaded portion of the coupling body) and a second external fastening cone (corresponding to the second internal fastening cone of the clamp ring). The clamp nut includes an opening at the external end thereof. In this way, the connection strength tends to be enhanced to solve the problem of poor connection strength of the conventional connector. | 07-07-2011 |
