Dynamic Conductive Connector

technical field

The invention relates to a dynamic conductive connection device used in electrical equipment for dynamic conductive connection.

Background technique

In all kinds of electrical equipment, it is often necessary to make conductive connections between relatively moving parts. For example, the cable reel used in power inspection and maintenance equipment to connect the temporary power supply of the electrical equipment, the cable input end on the cable reel needs to be connected to the temporary power supply during its use, and the connection with the electrical equipment When the cable drum is often moved or rotated, this dynamic connection method brings certain difficulties to on-site inspection and maintenance operations. Usually, the cables on the cable reel need to be released to the required length and position before wiring. Each wiring requires the operator to go back and forth between the electrical equipment and the temporary power supply many times, which reduces the work efficiency and improves the work intensity.

Contents of the invention

The technical problem to be solved by the present invention is to provide a dynamic conductive connection device with reliable connection and convenient operation and use.

The dynamic conductive connection device of the present invention includes a fixed shaft, at least one fixed disk is fixedly installed on the fixed shaft, and a stop ring connected to it is arranged at one end of the fixed disk; an annular arrangement formed between the stop ring and the fixed disk A moving ring coaxial with the fixed disk and rotatable is placed in the groove; one axial end of the moving ring is in plane contact with the surface of the fixed disk to form a conductive contact surface, and the other axial end of the moving ring is provided with a spring placement hole. A compression spring is arranged in the spring placement hole, and the outer end of the compression spring is pressed on the surface of the retaining ring through a ball; two installation holes for connecting with the moving terminal are arranged on the radially outer side of the moving ring.

The fixed shaft is the installation shaft of a cable reel, the body of the cable reel can rotate around the fixed shaft, the moving terminal on the moving ring is connected to the incoming cable of the cable reel, and the main body of the incoming cable is wound around the on the body of the cable reel.

The fixed plate is provided with a fixed terminal for connecting the outgoing cable, and the outgoing cable passes through the central hole on the fixed shaft and is led out from the end of the fixed shaft.

The present invention can realize the dynamic conductive connection through the relatively rotatable fixed disk and the moving ring; the structure of its rotation fit is especially suitable for the cable reel in the electric power overhaul and maintenance equipment, and the cable reel with this device can be used for temporary wiring. First connect the incoming cable to the temporary power supply, and then the body of the cable reel can be moved or rotated arbitrarily to retract the cable without affecting its conductive connection with the outgoing line end, without the operator's back and forth wiring and wiring, thereby reducing Increased work intensity and improved work efficiency.

Detailed ways

As shown in the figure, the dynamic conductive connection device includes a fixed shaft 1, on which a plurality of fixed disks 2 are fixedly installed, and one end of the fixed disk is provided with a retaining ring 3 connected thereto; between the retaining ring and the fixed disk A ring-shaped seating groove 4 formed is provided with a moving ring 5 coaxial with the fixed disk and rotatable; one axial end of the moving ring 5 is in plane contact with the surface of the fixed disk to form a conductive contact surface; A spring placement hole 6 is provided, and a compression spring 7 is arranged in the spring placement hole, and the outer end of the compression spring 7 is pressed on the surface of the retaining ring through a ball 8; The installation hole 10 connected with the connecting terminal 9, the moving connecting terminal can be connected with the temporary power supply or electrical equipment through the cable, and correspondingly, the fixed plate can be connected with the electrical equipment or the temporary power supply through the cable.

In the embodiment of the present invention, the fixed shaft 1 is the installation shaft of an ordinary cable reel, and the disc body of the cable reel can rotate around the fixed shaft 1, and the moving terminal 9 on the moving ring is connected with the incoming cable 11 to further The main body of the wire cable is wound on the cable drum. The fixed plate 2 is provided with a fixed terminal 13 for connecting the outgoing cable 12, and the outgoing cable 12 passes through the central hole on the fixed shaft 1 and is led out from the end of the fixed shaft. During the process of the reel rotating and releasing the incoming cable, the moving ring can rotate with the reel, which can keep the connection end of the incoming cable and the temporary power supply from being affected by the rotation of the cable reel, so it can be connected with the temporary power supply before the reel is released. Wiring without having to go back to the temporary power supply for wiring after payout is done the traditional way.
