Described novel auxiliary switch, cam gear comprises drive block 9 and the cam 8 that matches and be connected, the centre bore inner ring of described cam 8 is provided with ratchet, drive block 9 centers have the prismatic hole that is complementary and is connected with transaxle 7 profiles, the top of drive block 9 is provided with toothed disc 13, and described toothed disc 13 is meshed with the ratchet of cam 8 centre bore inner rings.
Described novel auxiliary switch, transaxle 7 tops of conversion operating mechanism are fixed with ring flange 10, turn of bilge 2 connections place are provided with axle sleeve 11 and sheath 12 on transaxle 7 and the mounting panel, described cam gear is nested on the transaxle 7 successively, is provided with between topmost cam 8 and axle sleeve 11 and compresses spring 14.
Described novel auxiliary switch is provided with adjustment cushion block 6 between two sensitive switches topmost of both sides on the connecting screw rod between the upper and lower turn of bilge 2,3 of mounting panel and last turn of bilge or two sensitive switches bottom and downward bent part.
The beneficial effects of the utility model:
1, the utility model auxiliary switch contact unit adopts sensitive switch, and every docking point is relatively independent, and reliable in action, good airproof performance, replacing are conveniently.Sensitive switch is corresponding one by one with cam set, utilizes cam to control the action of sensitive switch, and is directly simple, can guarantee the reliability of the action of each docking point; Because every docking point is independent adjustable, can flexibly contacts status be carried out the conversion of normally-open normally-close as required.
2, the utility model auxiliary switch contact adopts sensitive switch, because the mechanical endurance and the electrical endurance of sensitive switch all surpass 300,000 times, therefore in the useful life of having improved auxiliary switch greatly, the contact favorable sealing property of sensitive switch more can adapt to complicated environment for use simultaneously.Compare reliable in action height, long service life with F6 series auxiliary switch.
3, the utility model auxiliary switch cam gear has adopted adjustable design, each cam gear is made up of cam and drive block respectively, adopting some little teeth to be meshing with each other between them is assembled together, cam can be adjusted as required with respect to the position of drive block, make it corresponding contact sensitive switch and shift to an earlier date or hysteresis motion, thereby satisfy some particular requirements.
4, be directly to connect between the operating mechanism of the ring flange of the utility model auxiliary switch, square shaft composition and the cam set, do not have the clutch tripping mechanism, can reflect the motion state of high-voltage switch gear truly.
