Abstract
An aluminum alloy strain clamp is formed by a connector, a clamp body, a steel anchor, a drainage plate and a lead. The connector is an aluminum-alloy tubular body. A circumferential surface of the connector is provided with knurls. The clamp body is an aluminum-alloy tubular body whose front end is in a conical shape. A front end of the clamp body is provided with a conical crimping portion. A central rear portion of the clamp body is successively provided with a connector crimping portion and a steel anchor crimping portion. A front end of the steel anchor is a two-stage-step cylinder and a rear end is provided with an elliptical pulling ring. The two-stage-step cylinder is provided with several annular structures or annular grooves respectively. Positions of the clamp body, the steel anchor and an outer surface of the drainage plate, where corner angles should be located, are in an R angle design. One end of the lead is crimped with the connector. A rear half segment of the connector is crimped on a first step cylinder of the steel anchor. The drainage plate sleeves a rear-end step of the clamp body and is welded and fixed. Through crimping, the lead, the connector and the steel anchor are fixedly arranged in the clamp body. The structure is simple and installation is convenient.
