Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] As shown in Figure 1, the flexible sheath 1 made of plastic material hose can be equipped with fiber filler or double-layer stainless steel wire embedded in the plastic material. The function of the flexible sheath 1 is to install the electrical conductor 2 of the cable, and the electrical conductors 2 wrapped in an insulating layer can be twisted together, and a certain length margin is left in the sheath to allow its possible elongation Condition.

[0029] Insert the inner flange 4.3 end of the armor sleeve from the inner support 3 of the connector provided with the zigzag groove 3.1, stop at the end face of the outer flange 3.2 of the inner support 3 of the connector, and then insert the inner support 3 of the connector into the flexible The connection end of sheath 1 ends at its flange 3.3 end. By applying radial pressure in the ci...

Abstract

The invention discloses a draw-out type rotatable cable armoring connector, in particular relating to a cable connector which is used under severe environment of mining industry and the like, and resolves the technical problem that the existing armored cable connector can not rotate to adjust plugging angle. The draw-out type rotatable cable armoring connector comprises a flexible protective sheath filled with an electric conductor, the end of the protective sheath is sleeved on an internal support of the connector and clamped between the connector internal support and an armoring in tensile and sealing modes, the connector internal support is connected with the jacket of a connector filled with a plug head, the plug head is provided with a galvanic coupling connecting element which is electrically connected with the electric conductor of the cable and is composed of a socket and / or a plug, the inner wall of the connector jacket is provided with an internal arc-shaped ring groove, an external arc-shaped ring groove is arranged in a corresponding position of the outer wall of the connector internal support, and a ring-shaped spring steel wire is arranged in a ring groove formed by the internal arc-shaped ring groove and the external arc-shaped ring groove. The draw-out type rotatable cable armoring connector can be widely used in various cable connecting devices.

Description

technical field [0001] The invention relates to a cable connector, in particular to a cable connector used in harsh environmental conditions such as mining, and is mainly used for underground mine control equipment. Background technique [0002] Weak current cables are widely used in the downhole environment. Cables or electrical conductors covered with insulating layers are often set in flexible protective sheaths, generally using metal armor or rubber plastic sheaths filled with fiber layers. The mechanical strength of the cable joint is protected under tensile load, and the connection joint that realizes the electrical connection between the conductors is at the end of the sheath. [0003] The armored cable joint that people usually understand and use is an integral solid connection, which is used for the mechanical connection between the connecting part and the sheath and the mechanical and electrical connection with the matching connecting part, such as the armored Thi...
