Abstract

The invention relates to a hoop self-pressing fixing type binding post comprising a binding post body. One end of the binding post body is a cable inserting part, and the other end is an external connecting part or a cable inserting part. The external connecting part is provided with an installation hole. The external end part of the cable inserting part is the cylindrical connecting part, and the bottom part of the cable inserting hole is provided with the cable inserting fixing core groove, and the external surface of the cylindrical connecting part is provided with the external threads. The cylindrical connecting part is connected with a pressing nut in a screwed manner, and a hoop fixing ring is slidably disposed in the cable inserting hole. The hoop fixing ring is provided with an open type telescopic notch, and the inner surface of the hoop fixing ring is at least provided with the annular projection used for preventing the shedding of the cable. The hoop self-pressing fixing type binding post is advantageous in that the installation and the connection are convenient, the crimping area of the cable cannot be broken, and the reliable contact of the cable can be guaranteed; the requirement of the flowing of the enough current can be satisfied, and the safety hidden troubles and the phenomenon of the power interruption caused by the infirm connection can be reduced; the hoop self-pressing fixing type binding post can be used in a repeated manner, the use costs can be reduced, and the resource waste can be reduced.

Description

technical field [0001] The invention belongs to the technical field of power electronic wiring, and in particular relates to a hoop self-pressing fastening type terminal for fastening the lead-out ends of wire cores of electric wires and cables. Background technique [0002] As we all know, the transmission of electric energy is completed through wires and cables, and the terminal block is an accessory product used to realize electrical connections, which is divided into the category of connectors in the industry. With the increasing degree of industrial automation and stricter and more precise industrial control requirements, the amount of terminal blocks is gradually increasing. With the development of the electronics industry, the use of terminal blocks is increasing, and there are more and more types. At present, for large round cables with multi-strand spiral cores, the wire cores are generally inserted into the cable insertion holes of the terminal blocks when connect...
