One-step buckling and molding type cable connector

Abstract

The invention discloses a one-step buckling and molding type cable connector which comprises a connecting head arranged at the end of a cable, wherein the connecting head consists of a step sleeve and a step core which are sequentially sleeved at the end of the cable from outside to inside; the peripheral surface of a small-diameter pipe of the step sleeve is provided with an annular boss, and a groove is formed between the annular boss and a step table of the step sleeve; a small-diameter pipe of the step core extends into a cable jacket, and a large-diameter pipe of the step core is sleevedon the small-diameter pipe of the step sleeve; the end part combining surfaces of the step core and the annular boss of the step sleeve are respectively provided with arc pin holes along the axial direction, and pin shafts are arranged in the pin holes; a protective sleeve extends from the groove of the small-diameter pipe of the step sleeve to the cable jacket; and a socket electrically connected with a conductor in the cable is inserted in the large-diameter pipe of the step sleeve. The invention solves the problems that the traditional cable connector cannot rotate, the jacket is easy to pull out, and molding cannot be finished at one step. The invention is suitable for connecting cables for equipment control under a coal mine well.

Description

technical field [0001] The invention relates to a cable connector used in underground coal mines, in particular to a one-time crimping type cable connector. Background technique [0002] The underground environment of coal mines is humid and dusty, and is vulnerable to solid falling objects such as crushed coal and gangue. The cables used for control equipment generally use metal armor sheaths or rubber plastic sheaths filled with fiber layers. The connection joint, which protects the mechanical strength of the cable end under tensile load and realizes the electrical connection between the conductors, is arranged at the end of the sheath. At present, the armored cable joints used in the underground are integrally consolidated, and require secondary assembly, and the processing is relatively cumbersome. At the same time, the cable joints cannot adjust the plugging angle, and the overall cable cannot be placed and twisted freely. Contents of the invention [0003] The purpo...
