Abstract
The utility model discloses a kind of improvement structures of timer for electric cooker switch, cam when including the reed switch being set on switch base and walking, reed switch is made of static contact spring piece and movable contact spring, static contact spring piece and movable contact spring cooperation are oppositely arranged, movable contact spring has enhancement layer, the triangle boss of the notch cooperation of cam, triangle boss are integrally bended by movable contact spring when being convexly equipped with and walk on movable contact spring.Service life can be improved in the improvement structure of timer for electric cooker switch.
Description
Technical field:
The utility model relates to a kind of timer switch, are especially a kind of improvement structure of timer for electric cooker switch.
Background technique:
The timer switch structure of the prior art, can only come cam when cooperating to walk by the injection-moulded plastic jacking block on movable contact spring
Reach 10,000 mechanical endurance tests, has been unable to meet client's quality requirements growing to timer.
Utility model content:
Technical problem to be solved by the utility model is to provide a kind of timer for electric cooker that service life can be improved
The improvement structure of switch.
The technical solution of the utility model is to provide a kind of improvement structure of timer for electric cooker switch, including sets
It is made of with cam, reed switch when walking static contact spring piece and movable contact spring in the reed switch on switch base, static contact spring piece and movable contact spring are matched
Conjunction is oppositely arranged, and movable contact spring has enhancement layer, the triangle boss of the notch cooperation of cam, triangle when being convexly equipped with and walk on movable contact spring
Boss is integrally bended by movable contact spring.
After using the above structure compared with prior art, the utility model has the advantage that by the way that enhancement layer is arranged, and increases
Movable contact spring song is added to take stress intensity, the molding triangle boss of projection is convex to substitute original plastics and movable contact spring integrally bends
Platform improves wear-resistant strength, so that timer is through 20,000 mechanical endurance test qualifications.
Preferably, enhancement layer is copper foil, copper foil is consistent with movable contact spring length and width, copper foil and movable contact spring one
Body formed setting makes movable contact spring with a thickness of 0.3mm.It improves song and takes stress intensity.
Preferably, the pointed surface of triangle boss is compounded with wearing layer.Enhance wearability.
Preferably, wearing layer is enamel layer, enamel layer is sintered in the pointed surface of movable contact spring.
Preferably, the rear end of movable contact spring and static contact spring piece is fastened on respectively in corresponding reed trough.
Further, the side wall of the notch of cam is arc surface when walking, and bottom wall is arc convex surface, side wall and the round and smooth mistake of bottom wall
It crosses.Cooperate with movable contact spring more smooth.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment:
The utility model is described in further detail with reference to the accompanying drawings and detailed description:
As shown in Figure 1, a kind of improvement structure of timer for electric cooker switch, including the reed switch being set on switch base 1
With cam 2 when walking, reed switch is made of static contact spring piece 3 and movable contact spring 4, and the rear end of movable contact spring 4 and static contact spring piece 3 is fastened on phase respectively
It answers in reed trough, static contact spring piece 3 and the cooperation of movable contact spring 4 are oppositely arranged, and take stress intensity to improve movable contact spring song, movable contact spring 4 has
Enhancement layer, enhancement layer are the copper foil of 0.5mm, and copper foil is consistent with movable contact spring length and width, copper foil and movable contact spring one
Molding setting makes movable contact spring thickness increase to 0.3mm, the triangle boss of the notch cooperation of cam when being convexly equipped with and walk on movable contact spring 4
41, triangle boss 41 is integrally bended by movable contact spring.
Also, in order to improve wearability, the pointed surface of triangle boss 41 is also compounded with wearing layer.Wearing layer is enamel
Layer, enamel layer are sintered in the pointed surface of movable contact spring.In order to which the notch of cam when making the triangle boss of movable contact spring and walking cooperates more
Smooth, the side wall of the notch 21 of cam is arc surface when walking, and bottom wall is arc convex surface, side wall and bottom wall rounding off.
Thickness by increasing movable contact spring can significantly improve song and take stress intensity to 0.3mm, and integrally be beaten by movable contact spring
When the triangle boss of roll forming and the notch of cam when walking cooperate, wearability is improved, and is prolonged the service life, after tested, timer
Through 20,000 mechanical endurance test qualifications.
Only the utility model preferred embodiment is described above, but is not to be construed as the limit to claim
System.All equivalent structure or equivalent flow shifts done using the utility model specification and accompanying drawing content are included in this
Within the scope of patent protection of utility model.
