Abstract
The utility model relates to a single-phase isolating switch on an outdoor pillar, which comprises a base and two insulating support pillars fixed on the base, wherein a left wiring plate and a right wiring plate are respectively arranged at the top ends of the insulating support pillars; a fixed contact is arranged on the left wiring plate; a shaft base is arranged on the right wiring plate; a switch blade is hinged with the shaft base; the switch blade is provided with two contact blades; a compression spring is arranged outside the switch blade; the single-phase isolating switch is characterized in that a latching device is arranged on the switch blade; and the fixed contact is provided with a position locking plate matched with the latching device. The latching device is arranged, so that the switch-on/off state of the product can be locked. The switch blade can be operated only after the latching device is unlocked, so that the safety in use of the product is ensured.
Description
Technical field
The utility model relates to single-phase isolating switch on a kind of outdoor post.
Background technology
Usually, single-phase isolating switch is the vertical Unclosing structure of single break on the outdoor post, mainly contains base, post insulator, main conductive circuit part.During operation, adopt gram to make the hook plate on the excellent hook moving knife lock, make its disengaging or be hooked on fixed contact anticreep draw-in groove.Isolating switch on the existing post does not have anti-misoperation apparatus, causes the accident that jeopardizes the person and device security easily.
Summary of the invention
The purpose of the utility model is to overcome the defective of prior art, provides a kind of and have latching device, can prevent single-phase isolating switch on the outdoor post of misoperation.
For realizing above-mentioned purpose, the utility model adopts single-phase isolating switch on a kind of so outdoor post, comprises base; Be fixed in two insulation columns on the described base, described insulation column top is respectively equipped with left terminal block and right terminal block, and described left terminal block is provided with fixed contact; Described right terminal block is provided with axle bed; Be hinged with plug-in strip on the described axle bed, described plug-in strip has two contact knife sheets, and the outside of described plug-in strip is provided with the compression spring; Described plug-in strip is provided with locker, and described fixed contact is provided with the lock-bit plate that cooperates with described locker.
Especially, the jointed shaft of described plug-in strip and described axle bed is provided with the separating brake limiting plate.
Especially, be equipped with one group of more than connection bolt of one on described left terminal block and the described right terminal block.
Compared with present technology, the beneficial effect of the utility model is embodied in:
Through locker is set, product can be locked close a floodgate and gate-dividing state, only after to the locker release, could operate plug-in strip, thus the fail safe of assurance product use.
In addition, the separating brake limiting plate is set on jointed shaft, the plug-in strip branch is had no progeny be still in the maximum angle position, reduced mechanical wear, prolonged the useful life of mechanism;
Left side terminal block and right terminal block adopt a more than connection bolt to fix, and the conducting wire is firmly installed, and reason external force does not influence and becomes flexible, and has improved the electric conductivity of product.
