Technical Field

The invention relates to a connecting device, in particular to an anti-drop cable joint for an electric power system, and belongs to electric power equipment.

Background

Cable is a generic term for optical cables, electrical cables, and the like. The cable has many purposes, is mainly used for controlling installation, connecting equipment, transmitting power and other multiple functions, and is a common and indispensable object in daily life. Installation requires special care since the cable is live. The power cable is formed by extruding (winding) an insulating layer outside a conductor, such as an overhead insulated cable, or twisting several cores (corresponding to a phase line, a zero line and a ground wire of a power system), such as an overhead insulated cable with more than two cores, or additionally arranging a sheath layer, such as a plastic/rubber sleeve wire cable. The main process technologies include drawing, twisting, insulation extrusion (lapping), cabling, armoring, sheath extrusion and the like, and different process combinations of various products have certain differences. In electric power system, often need connect the cable end and increase the length of cable, constitute overall structure and realize the transmission of electric power, because the cable all adopts the wire to make, when two cables are connected, only twine two cables each other, because the toughness of metal etc. lead to the winding nature between the cable not enough, produce after working a period and drop etc. easily, cause the inefficacy of connecting.

Disclosure of Invention

The invention aims to solve the problem that the connection between the existing cables is easy to fall off, and designs an anti-falling cable joint for an electric power system.

The purpose of the invention is realized by the following technical scheme: a anticreep type cable joint for electric power system, including interconnect's connector one and connector two, the terminal surface of connector one and the end face contact of connector two, and the central line of connector one and the central line setting of connector two are on same straight line, the equal indent of one end that connector one and connector two kept away from each other forms the recess, the recess communicates with the wall of corresponding connector one or connector two respectively, all set up the spooler in the recess, and the both ends of spooler all are fixed with the wall of recess, there is the clearance bottom of spooler and recess. Through all setting up the spooler in connector one and connector two, correspond the winding on the spooler with the cable, and the clearance that exists in the bottom of spooler and recess will be greater than the diameter of cable, this is the cable of being convenient for passes, the cable winding is on the spooler and fix on the spooler, because connector one and connector two fixed connection, just so realized the connection of two cables, the problem that the contact fixation drops easily between the traditional cable has been solved, utilize this connector, can be connected with two cables respectively, it is fixed effectual, make the cable long-term work also can not drop.

The winder comprises a roller, a rotating shaft is arranged in the roller, two ends of the rotating shaft penetrate through the roller and then are arranged in the side walls of the corresponding grooves, the roller can rotate around the rotating shaft, a gap exists between the wheel surface of the roller and the bottom of the groove, and the central line of the rotating shaft is perpendicular to the central line of the first connector or the second connector; two ends of the rotating shaft respectively penetrate through the corresponding first connecting head or the second connecting head; the wheel surface of the roller is concave to form an annular groove, and the bottom surface of the annular groove is arc-shaped. The utilization sets up the wheel face with the gyro wheel for behind the arc recess, conveniently compresses tightly the cable on the gyro wheel along the cambered surface, along with the rotation of pivot, can twine on the gyro wheel fast, accomplishes the end of cable and twines a week after, fixes the cable end through buckle etc. realizes like this that two cables pass through the connection of connector, and the electric current can transmit.

One end of the first connector, which is in contact with the second connector, is provided with a threaded column, one end of the threaded column is arranged outside the first connector, the threaded column is vertically welded on the end face, and the center line of the threaded column is superposed with the center line of the first connector; and one end of the second connector, which is contacted with the first connector, is recessed inwards to form a threaded hole, the central line of the threaded hole is superposed with the central line of the second connector, and the threaded column is screwed in the threaded hole. Utilize the cooperation of screw thread post and screw hole, link together connector two and connector one, close the back at the screw thread post soon simultaneously, connector two is the contact with the terminal surface of connector one, just so can realize the wholeness of connecting, guarantees that the electric current can transmit.

In conclusion, the beneficial effects of the invention are as follows: the connecting device is simple in structure, can be connected and fixed with two cables by utilizing the two connectors, is good in fixing effect, enables the cables not to fall off even in long-term work, and realizes electric power transmission.
