Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
As shown in Fig. 1-Fig. 3, the utility model discloses a kind of N pole switch of miniature circuit breaker reclosing device, comprise stationary contact bonding jumper 2, movable contact spring 1 and axle sleeve handsetting gear, described stationary contact bonding jumper 2 comprises the first stationary contact bonding jumper 21 and the second stationary contact bonding jumper 22, breach 5 is provided with between first stationary contact bonding jumper 21 and the second stationary contact bonding jumper 22, first stationary contact bonding jumper is connected with the binding post at miniature circuit breaker two ends respectively with the other end of the second stationary contact bonding jumper, described axle sleeve handsetting gear comprises axle sleeve handsetting gear body 4, in the utility model specific embodiment, described movable contact spring touches phosphorus bronze sheet for dynamic, namely movable contact spring is made up of phosphor-copper material, wherein phosphor-copper adds degasser phosphorus P content 0.03 ~ 0.35% by bronze, Theil indices 5 ~ 8% and other trace element are as iron Fe, zinc Zn etc. form ductility, fatigue durability is all good be can be used for electrically and mechanical material, because phosphorus content is higher, its fatigue resistance is higher, elasticity and resistance to wear better, described axle sleeve handsetting gear body 4 is provided with fan-shaped drive division 3, described dynamic touch phosphorus bronze sheet 1 comprise connect successively connecting portion 11, convergence part 12 and curved portions 13, this connecting portion 11 is connected with the first stationary contact bonding jumper 21 electric welding, this connecting portion 11 and convergence part 12 are in obtuse angle, this curved portions 13 is arranged across breach 5, and curved portions 13 is positioned on the motion path of fan-shaped drive division 3, the first described stationary contact bonding jumper 21, second stationary contact bonding jumper 22, connecting portion 11 and convergence part 12 are tabular.
Stationary contact bonding jumper 2 and dynamic touching between phosphorus bronze sheet 1 are provided with the second phosphorus bronze sheet, this second phosphorus bronze sheet comprises the second connecting portion 14 and contact site 15, this second connecting portion 14 fits on connecting portion and convergence part, and contact site 15 and curved portions 13 form semiellipse shape cavity 16, described contact site 15 is tabular.
The vertical stroke of fan-shaped drive division 3 is greater than the vertical distance H between the end of contact site and the second stationary contact bonding jumper, ensure that dynamic phosphorus bronze sheet of touching effectively closes with stationary contact bonding jumper by fan-shaped drive division 3 on axle sleeve handsetting gear, dynamicly touch phosphorus bronze sheet and the second phosphorus bronze sheet to get back to initial position at axle sleeve handsetting gear be lean on elasticity own to upspring reset.
By adopting technique scheme, adopt flat modular construction to instead of the structure of original arc shape parts, in the course of processing, effectively reduce the requirement of quality of fit, processing technology is easy, thus reduces production cost.
The operation principle of this N pole switch is: the fan-shaped drive division on axle sleeve handsetting gear body is in rotation process, curved portions is driven to move to the second stationary contact bonding jumper direction, touch phosphorus bronze sheet and the second stationary contact bonding jumper electrical contact until dynamic, now achieve the closed of N pole switch; Otherwise when axle sleeve handsetting gear resets, the fan-shaped drive division now on axle sleeve handsetting gear body leaves curved portions, now dynamic tactile phosphorus bronze sheet utilizes the elastic force resilience of self, until recover ortho states, now achieves the disconnection of N pole switch.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
