Embodiment
For accompanying drawing, embodiments of the invention are described further below:
As shown in the figure, a kind of snap device of low-voltage electrical apparatus, described low-voltage electrical apparatus is miniature circuit breaker, contactor or relay, comprise pedestal 1 and buckle 2, described pedestal 1 is provided with guide rail, described pedestal 1 both sides are respectively equipped with the first slide rail 3 and the second slide rail 4, described first slide rail 3 is provided with the first tilted block 5 and the second tilted block 6 for the unidirectional slippage of buckle 2, described first tilted block 5 is provided with the first inclined plane 51, described second tilted block 6 is provided with the second inclined plane 61, inner side on described second slide rail 4 is provided with the chuck 8 for the unidirectional slippage of buckle 2, described buckle 2 comprises the card base 9 of both sides and is positioned at middle card article 10, the both sides of described card article 10 are provided with boss 11, the middle part of described card article 10 is provided with groove 12, and described boss 11 is positioned at the rear of card base 9 relative to buckle 2 glide direction, described second slide rail 4 is provided with stopper slot 13, described buckle 2 forms primary importance and the second place along guide rail slippage, described primary importance: push up press-fit for card base 9 and the first inclined plane 51 and shrink to the inside and slip over the second inclined plane 61 place that the first tilted block 5 is positioned at the second tilted block 6, the described second place: push up press-fit for card base 9 and the second inclined plane 61 and shrink to the inside and slip over the second tilted block 6, and shrink to through hole 12 place and slip over chuck 8 to terminate in stopper slot 13 for boss 11 pushes up pressure the 3rd inclined plane 81.Adopt said structure, due to the contraction in length of card base, its elastic force increases, and improves position stability, when buckle 2 is installed, buckle 2 is pushed from guide rail, and card base 9 is along the first slide rail 3 slippage, and first the card base of buckle both sides slides along the first tilted block 5, first inclined plane 51 push up pressure card base 9 make card base 9 to its inside shrink slide on the second tilted block 61, and now boss 11, along the second slide rail 4 slippage, is drawn close towards chuck, chuck plays the function of positive stop lug boss.Because boss 11 is arranged on the both sides of card article 10, the middle part of card article 10 is provided with groove 12, the shape of this groove 12 can be strip, ellipse or sidewall for the shape such as supply laterally, and boss 11 is understood groove 12 place when pushing up press with chuck 8 and shunk thus slip over chuck 8.Because boss 11 to chuck 8 stroke is comparatively large, when there will not be product to be installed on guide rail, occur that buckle can not automatically reset phenomenon, thus effectively avoid user to promote excessively to cause can not effectively screens.And according to such scheme, by the card base 9 of buckle 2 side, then position in conjunction with the boss 11 on two card articles 10 in the middle of buckle 2, thus increase the shift motion of buckle 2, effectively prevent buckle 2 slide transitional from causing location inaccurate, thus bring convenience to installation.
In the present embodiment, described boss 11 is provided with slip plane 111, first angled transition face 112 and the screens plane 113 of arc, described chuck 8 be provided with distribute successively the 3rd inclined plane 81, horizontal plane 82, second angled transition face 83 and vertical plane 84, described slip plane 111 coordinates with described 3rd inclined plane 81 slippage, and described screens plane 113 and described vertical plane 84 are unidirectional spacingly to be coordinated.During slippage, the slip plane 111 of boss 11 slides along described 3rd inclined plane 81 and through horizontal plane 82, and the first angled transition face 112 is corresponding with the second angled transition face 83, until boss 11 slips in stopper slot 13, and screens plane 113 forms spacing cooperation with vertical plane 84.Adopt above-mentioned Sliding Structures, have that positioning function is good, stability is high, accuracy is high and the advantage such as serviceability is good.
In the present embodiment, the front being positioned at described chuck 8 relative to buckle 2 glide direction is provided with the stopper slot 13 matched with described boss 11.Arrange stopper slot 13 by the front of the chuck 8 on the second guide rail of pedestal, make buckle 2 when sliding, boss 11 slips over chuck 8 and is positioned at stopper slot 13, plays the object of location.
In the present embodiment, a kind of miniature circuit breaker, comprises shell 7, also comprises described snap device, and pedestal 1 and the shell 7 of described snap device are wholely set.Pedestal 1 is the bottom of the shell 7 of this miniature circuit breaker, by arranging the snap device of said structure on shell, making this miniature circuit breaker when guide tracked installation, having easy for installation, accurate positioning and the high advantage of stability, effectively raise the serviceability of product.
Embodiment should not be considered as the restriction to invention, but anyly done based on spirit of the present invention
Improvement, all should within protection scope of the present invention.
