Abstract
The invention discloses an isolating switch consisting of a base, a porcelain insulator, a moving contact (2) and a patch board (1). The isolating switch is characterized in that: the patch board (1) is provided with an extending section (11) which extends to the inner side of the porcelain insulator; an anti-release piece (3) is fixed on the extending section (11); and an auxiliary fixed contact (4) is fixed on the extending section (11). The isolating switch has a long service life.
Description
Technical field
The present invention relates to a kind of isolating switch, especially a kind of isolating switch that replaces spring mousing-hook and the auxiliary fixed contact of increase with the anti-avulsion sheet.
Background technology
At present, prior art isolating switch prevent deprotection with the spring mousing-hook.This isolating switch has following shortcoming: the first, because isolating switch generally is installed in outdoorly, spring corrosion with the passage of time, mousing-hook just lose protective effect, cause isolating switch to scrap, and the useful life of isolating switch is short; The second, because electric interface is few, the aging of isolating switch quickened in heating sparking easily, also is to cause isolating switch short reason in useful life.Therefore, designing a kind of isolating switch of long service life, is the present technical issues that need to address.
Summary of the invention
Technical problem to be solved by this invention provides a kind of isolating switch of long service life.
The technical scheme that the present invention solves its technical problem is:
A kind of isolating switch is made up of base, porcelain vase, fixed contact, moving contact and terminal block, and the extension that stretch out the oriented porcelain vase of terminal block inboard is fixed with the anti-avulsion sheet on the extension.
Because the anti-avulsion sheet is difficult for getting rusty, prolong the useful life of isolating switch.
Preferably, on the extension, be fixed with auxiliary fixed contact.
Owing to increased electric interface, avoided the heating spark phenomenon, further prolong the useful life of isolating switch.
Further preferably, described anti-avulsion sheet is processed by elastic steel sheet, has " V " shape anticreep protruding in the end of elastic steel sheet, and " V " shape anticreep convexity just in time catches on the outward flange of the moving contact that constitutes isolating switch when isolating switch is closed.
Again further preferably, be provided with the guide part that play the guiding role in the end of described auxiliary fixed contact to the bending of contact-making surface rightabout.
Further preferably, the extension that stretch out all oriented porcelain vase of the left and right terminal block inboard of isolating switch all is fixed with the anti-avulsion sheet on the extension; The extension that stretch out all oriented porcelain vase of the left and right terminal block inboard of isolating switch all is fixed with auxiliary fixed contact on the extension.

Fig. 1 is a structural representation front view of the present invention;
Fig. 2 is the rearview of Fig. 1;
Fig. 3 is along the profile of A-A line among Fig. 1;
Fig. 4 is the sketch map of background technology.
Embodiment
Like Fig. 1-shown in Figure 3, a kind of isolating switch is made up of base, porcelain vase, fixed contact, moving contact 2 and terminal block 1, and the extension 11 that stretch out terminal block 1 oriented porcelain vase inboard is fixed with anti-avulsion sheet 3 on extension 11.
On extension 11, be fixed with auxiliary fixed contact 4.
Described anti-avulsion sheet 3 is processed by elastic steel sheet, has " V " shape anticreep protruding 5 in the end of elastic steel sheet, and " V " shape anticreep protruding 5 just in time catches on the outward flange of the moving contact 2 that constitutes isolating switch when isolating switch is closed.
Be provided with the guide part 6 that play the guiding role to the bending of contact-making surface rightabout in the end of described auxiliary fixed contact 4.
The extension 11 that stretch out all oriented porcelain vase of left and right terminal block 1 inboard of isolating switch all is fixed with anti-avulsion sheet 3 on extension 11.
The extension 11 that stretch out all oriented porcelain vase of left and right terminal block 1 inboard of isolating switch all is fixed with auxiliary fixed contact 4 on extension 11.
