Description
Technical field
The utility model relates to a kind of switch assembly, particularly relates to a kind of switch assembly that can adjust degree of tightness and reduce the improvement of electric arc generation.
Background technology
The rotary switch assembly is used in many common electrical appliances, as electric oven, washing machine or gas oven etc., make inner cam rotate cooperation mutually by rotating rotary switch with inner different switched terminal, and then drive electrical appliance with different section speed or power effect, though rotary switch is quite common on various electrical appliance, structurally still has many defectives, causes user's inconvenience, very the person more can make the infringement of electrical appliance or cause dangerous generation.
Its first defective as shown in Figure 1, have the switch place generalized section of known switch assembly now, comprise a base A, one camshaft D, one latch E, an one setting circle post F1 and a location flexible member F2, make the rotation of this camshaft D chimeric mutually fixing by rotating this latch E to adjust different sections with this positioning cylinder F1, when the user rotates latch E, must be according to the coefficient of elasticity of location flexible member F2, bestow different torsion, if coefficient of elasticity is big, then the user must impose bigger strength, otherwise, if user's strength is less, then having the situation that is difficult to rotate takes place, relatively, if coefficient of elasticity is little, then can be because of rotation too easily, and skip more than one section because of carelessness, cause the inconvenience in the use.
Please continue to consult Fig. 2 again, be to have the cam of known switch assembly and the generalized section that opens circuit of terminal now, comprise a base A`, two contact terminal B, one and switch terminal C, crimping flexible member C1, a camshaft D` and a latch E`, driving this camshaft D` by this latch of rotation E` supports this switched terminal C and then compresses this crimping flexible member C1, make this contact terminal B and switched terminal C form and open circuit, by finding two point defects among the figure:
Contact terminal B can produce electric arc when contacting conducting with switched terminal C, both connect with single-point, the electric arc that is produced can only be put release whereby, if the electric arc that produces is crossed conference and is produced spark, cause contact point, close on the infringement of terminal and electrical appliance, more severe patient causes that fire causes causing harm of life.
Switched terminal C is by camshaft D` crimp, and separate with contact terminal B, when switched terminal C is extruded distortion for a long time, can cause switched terminal C to produce deformation, and camshaft D` and crimping flexible member C1 not same axially on to the switched terminal C application of force, of long duration may cause the fracture of switched terminal C and the infringement of crimping flexible member C1.
This shows that above-mentioned existing switch assembly obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.In order to solve the problem of above-mentioned existence, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product does not have appropriate structure to address the above problem, this obviously is the problem that the anxious desire of relevant dealer solves.Therefore how to found a kind of switch assembly of improvement of new structure, real one of the current important research and development problem that belongs to, also becoming the current industry utmost point needs improved target.
