Abstract
The utility model relates to the field of eddy current retarder connecting box technology, specifically to a looseness-preventing and short circuit-preventing eddy current retarder connecting box comprising a connecting box base and a connecting box cover. The connecting box cover is installed on the outside of the connecting box base fixedly; a through groove in front-back direction is disposed in the connecting box base and front baffle plates are disposed in the through groove in a spaced manner; and a through groove in front-back direction is disposed in the rear portion of the connecting box cover and rear baffle plates corresponding to the front baffle plates are disposed in the through groove in the spaced manner. The looseness-preventing and short circuit-preventing eddy current retarder connecting box is reasonable in structure and easy to use, plays a role in fixing input leads and prevents touch short circuit through matching between the front baffle plates and the rear baffle plates, and achieves looseness-preventing and short circuit-preventing effects through studs and locknuts.
Description
Technical field
The utility model relates to current vortex retarder terminal box technical field, is a kind of locking anti-short circuit current vortex retarder terminal box.
Background technology
The eddy current retarder stators assembly causes conductor overheating to burn out broken string or short circuit phenomenon because operating current is large easily, therefore has serious potential safety hazard.
Summary of the invention
The utility model provides a kind of locking anti-short circuit current vortex retarder terminal box, has overcome the deficiency of above-mentioned prior art, and it can solve the eddy current retarder stators assembly because operating current is large, causes easily conductor overheating to burn out the problem of broken string or short circuit.
A kind of locking anti-short circuit current vortex retarder terminal box, comprise terminal box base and terminal box gland, the terminal box gland is fixedly mounted on the outside of terminal box base, the groove of fore-and-aft direction in terminal box base, in groove, be intervally distributed with front apron, the groove of fore-and-aft direction is arranged at the rear portion of terminal box gland, in groove, be intervally distributed with the backboard corresponding with front apron.
On the terminal box gland of above backboard top installing hole is arranged, terminal box base above front apron has the groove corresponding with installing hole, in installing hole and groove studs is arranged, terminal box gland and terminal box base are fixedly installed togather by studs, stop nut, pad.
The utility model is rational in infrastructure, and is easy to use, by the cooperation of front apron and backboard, input lead played positioning action, avoided the touching short circuit phenomenon, reached the effect of locking anti-short circuit by studs, stop nut.
