Method for connecting cable and miniature plug and miniature cable plug thereof

Abstract

The invention relates to a method for connecting a cable and a miniature plug and a miniature cable plug thereof. A core wire of the cable is connected with a contact body of the plug; a shielding layer (2) of the cable is clamped in a conical surface annular clearance between a plug shell (3) and a compression connecting sleeve (5); a binding cavity of the cable is arranged between the tail section of the plug shell (3) and the cable; the diameter of a through hole of the plug shell (3) is smaller than the inner diameter of the binding cavity, and a step structure is formed between the through hole of the cable and the binding cavity; and the cable surface between a root part with a conical structure of the shielding layer of the cable and the through hole of the cable is bound by a binding wire and combined with the step surface of the plug shell (3) to prevent the cable from being pulled away. The invention conducts the pulling force of the cable to the step surface by the binding wire by simply binding, prevents force from applying on the core wire, prevents the cable from being pulled away and solves the problem of the cable pulling of the miniature plug without designing anyspecial pulling prevention part. The invention solves the problem by a binding method, thereby simplifying a plug structure and reducing the manufacture difficulty and the manufacture cost.

Description

technical field [0001] The invention relates to a connection method between a cable and a small plug and the small cable plug, belonging to the field of electrical technology. Background technique [0002] At present, for the connection between the cable and the plug, in order to prevent the cable from protruding, a special anti-protrusion component is provided at the tail of the plug housing. The shell, so as to avoid the core wire and the shielding layer from coming out under force. For a plug with a larger structure, the internal space of this structure is sufficient, and it is not a problem to arrange a special anti-loosening component, but it is more difficult to realize for a small plug. Contents of the invention [0003] The task of the present invention is to provide a method for connecting a cable to a miniature plug, which solves the problem of the cable coming out with a simple structure. At the same time, the present invention correspondingly provides a small...
