Technical Field

The invention relates to a wiring device, in particular to a variable chuck wiring device.

Background

At present, many devices applied to a power grid need to be tested through tests, for example, a mutual inductor needs to be tested in an electric connection mode. The testing devices are generally provided with wiring screw holes for connecting wires, but the wiring screw holes on the testing devices are different in aperture (the wiring screw holes on the testing devices of different models of the same type of testing devices are also different in aperture), so that a lot of time is consumed for searching bolts matched with the wiring screw holes of various testing devices in the test process, and the work efficiency of the test is reduced.

Disclosure of Invention

The invention aims to provide a variable chuck wiring device which can be suitable for wiring screw holes with different apertures on a test device so as to facilitate test wiring and improve the inspection working efficiency.

The technical scheme of the invention is as follows:

a variable collet termination comprising: the hand-tight chuck comprises a chuck body and a plurality of movable clamping jaws uniformly distributed on the chuck body, each movable clamping jaw is provided with a clamping arm, the chuck body, the movable clamping jaws and the clamping arms are made of conductive materials, and the hand-tight chuck drives the clamping arms to move radially by utilizing the radial movement of the movable clamping jaws so as to fix the hand-tight chuck on a wiring hole of a test device; wiring structure, wiring structure including set up the connection screw on the chuck body and with the wiring bolt of connection screw adaptation.

The variable chuck wiring device is specifically used as follows, a clamping arm is inserted into a wiring hole of a test device; then, the movable clamping jaws drive the clamping arms to move radially, so that the hand tightening chuck is fixed on a wiring hole of the test device; then, through wiring bolt with experimental wire fixed connection on the chuck body to the realization will be tested wire fixed connection and on experimental device, it can adapt to the wiring screw of various different apertures on experimental device and use, so that experimental wiring improves inspection work efficiency.

Preferably, the head of the wiring bolt is further provided with an insulating operating handle for screwing or unscrewing the wiring bolt. So, can be used for screwing up or loosening the wiring bolt through insulating operating handle, realize the fixed of experimental wire and dismantle, its convenient operation not only, insulating operating handle can provide the safety guarantee for the staff operation moreover.

Preferably, the connection screw hole is provided on an end surface of the chuck body, and the connection screw hole is located on an end surface of the chuck body facing away from the movable jaw. So, be convenient for experimental wire installation and with the lift operation of dismantling.

Preferably, the end face, back to the movable clamping jaws, of the chuck body is provided with a mounting boss, and the connecting screw hole is formed in the end face of the mounting boss. Therefore, the structural arrangement in the chuck body cannot be influenced by the structure of the connecting screw hole, and the actual production and manufacturing are facilitated.

Preferably, the insulated operating handle includes a metal handle connected to a head of the terminal bolt and an insulating layer coated on an outer surface of the metal handle.

Preferably, the hand-tight chuck is a three-jaw hand-tight chuck.

Preferably, the hand tightening chuck further comprises an adjusting hand wheel arranged on the chuck body, and the adjusting hand wheel is used for driving the movable clamping jaws to move radially. The movable clamping jaws are driven to move radially by rotating the adjusting hand wheel, and the operation is convenient.

Preferably, the hand-tightening chuck is made of a metal material.

The invention has the beneficial effects that: the testing device can adapt to the wiring screw holes with different apertures on the testing device for use, so that the testing wiring is facilitated, and the testing work efficiency is improved.
