Abstract
The utility model provides a fastening type three -phase on -off device, including base, plug -in strip, contact piece and locking device, plug -in strip, contact piece and locking device all set up the upper surface at the base, and the plug -in strip includes 3 metal sheets and handle, and the upper end looks interval of 3 metal sheets is fixed on the handle, and the lower extreme of metal sheet is fixed on the base by fastening bolt, and the contact piece is 6 and is divided into 3 groups, set up respectively on the base that corresponds with the metal sheet position, and locking device is fixed plate and spring, the fixed plate setting in the both sides of contact piece, the spring setting is between fixed plate and the contact piece and between the 3 montage contacts, the fixed plate be bolted connection with the spring, contact piece and spring are welded connection. The utility model discloses a set locking device to parallel spring coupling for locking device is more firm, makes the plug -in strip be difficult for falling down, and spring structure life is longer.
Description
Technical field
The utility model relates to a kind of electrical device, particularly relates to a kind of fastening type three-phase break-make device.
Background technology
Knife switch is as a kind of important family and industrial circuit connecting valve, its stable type is also particularly important, existing most of knife switch does not all arrange loosing-proof device, to such an extent as to knife switch to use a period of time back switch blade just to there will be loosening, cause plug-in strip to fall, Circuit Interrupt, extremely bother, also have the knife switch being provided with locking device, but the anti-loosening component of existing Anti-loose knife switch is owing to being inclined design, so still firm not.
Summary of the invention
Main purpose of the present utility model is for prior art Problems existing, and proposes a kind of fastening type three-phase break-make device.
In order to achieve the above object, the technical solution of the utility model is as follows:
Break-make device involved by the utility model comprises base, plug-in strip, contact chip and locking device, described plug-in strip, contact chip and locking device are all arranged on the upper surface of base, described plug-in strip comprises 3 metallic plates and handle, the upper end of 3 described metallic plates is fixed on the upper of handle separately, the lower end of described metallic plate is fixed on base by fastening bolt, described contact chip is 6 and is divided into 3 groups, be separately positioned on the base corresponding with metallic plate position, described locking device is fixed head and spring, described fixed head is arranged on the both sides of described contact chip, described spring is arranged between fixed head and contact chip and between 3 groups of contact chips, described fixed head and spring are that bolt is connected, described contact chip and spring are for being welded to connect.
The described middle part often organizing two contact chips of contact chip is designed to the relative semicircular structure of circular arc, and leaves gap between semicircular structure.
Described contact chip is that copper alloy is made.
The thickness of described metallic plate is 2-3 times of the gap width of described two contact chips.
The spacing distance of described metallic plate is 20-30mm.
Described handle and base are that ceramic material is made.
The beneficial effects of the utility model are: the utility model connects by locking device being arranged to parallel spring, and make locking device more firm, in switch, plug-in strip not easily falls, and spring structure longer service life.
Accompanying drawing explanation
