The indicator provided by the utility model comprises an indicator board and a hinge part which are connected through a connecting plate. One side of the connecting plate is integrally connected with an elastic band plate, the other end of which is in a location fit with a shell. The indicator provided by the utility model has characteristics of convenient assembling, stable operation and long service life.
Description
Technical field
The utility model relates to a kind of miniature circuit breaker, refers in particular to a kind of miniature circuit breaker and carries the indicating device of returning device.
Background technology
Switch switchgear for power department is to guarantee Electrical Safety, carries out circuit and switches imperative equipment.The switching of breaker circuit shows that by the indicating device that is positioned at the circuit breaker upper end when contact closure, indicating device presents redness; When contact of breaker disconnected, indicating device presented green.Right existing indicating device is for being controlled the mode of the design that resets by the back-moving spring of peripheral hardware, assemble loaded down with trivial detailsly, and back-moving spring is the unsteady defective that comes off easily.
The utility model content
In order to overcome deficiency and the defective in the background technology, the utility model provides a kind of miniature circuit breaker and carries the indicating device of returning device, mainly solves existing miniature circuit breaker indicating device and has loaded down with trivial details, the poor stability of structure, the problem that back-moving spring easily floats and comes off.
The technical solution of the utility model is: a kind of indicating device that carries returning device, comprise indicator board and articulated section, described indicator board is connected by connecting plate with the articulated section, and a side of described connecting plate is connected with the elasticity band plate, and the other end of described elasticity band plate cooperates with the housing location.
Described elasticity band plate bending two ends forms the S shape.
The opposite side S profile of the corresponding connecting plate of described elasticity band plate is provided with the positioning round table that cooperates with the housing location.
Described technical scheme also includes: a kind of miniature circuit breaker, comprise housing, tripping, snap close and above-mentioned indicating device, central shaft rotation on described snap close and the housing cooperates, be hinged with the support seat corresponding with snap close on the described central shaft, described tripping is hinged with supporting the seat upper end, described support seat upper end is provided with spacing cylinder, and described indicating device is provided with the spacing draw-in groove that matches with spacing cylinder, and described indicating device cooperates with the housing location by the elasticity band plate.
The beneficial effects of the utility model: owing to take such scheme, a kind of miniature circuit breaker of the present utility model and carry the indicating device of returning device, the elastic webbing plate structure design that is wholely set has the effect of spring, change the mode that existing indicating device and its back-moving spring design respectively, had the characteristics of easy to assembly, stable operation and long service life.
Description of drawings
Fig. 1 is the structural representation of indicating device in the utility model.
Fig. 2 is the structural representation of the middle-size and small-size circuit breaker of the utility model.
Fig. 3 is the structural representation of supporting seat among Fig. 2.
Among the figure, indicator board 1, articulated section 2, connecting plate 3, positioning round table 4, elasticity band plate 5 is supported seat 6, spacing draw-in groove 7, spacing cylinder 8, housing 9, tripping 10, snap close 11, central shaft 12.
Embodiment
At accompanying drawing embodiment of the present utility model is described further below.
Carry the specific embodiment of the indicating device of returning device:
Shown in figure, the indicating device that this carries returning device comprises indicator board 1 and articulated section 2, and described indicator board 1 is connected by connecting plate 3 with articulated section 2, one side of described connecting plate 3 is connected with elasticity band plate 5, and the other end of described elasticity band plate 5 cooperates with housing 9 location.The elasticity band plate that is wholely set 5 adopts the material with elastic performance to make, and has the effect of spring, has changed the mode of existing indicating device and its back-moving spring split-type design, has the characteristics of easy to assembly, stable operation and long service life.
Described elasticity band plate 5 bending two ends form the S shape, and the structural design of special " S shape " has the effect of spring, and stable operation is good.
The opposite side S profile of described elasticity band plate 5 corresponding connecting plates 3 is provided with the positioning round table 4 that cooperates with housing 9 location.Positioning round table is higher than the setting of " S " profile, and not positioning when guaranteeing product work is not turned on one's side, and has the characteristics of simple in structure, working stability and long service life.
The specific embodiment of miniature circuit breaker:
Shown in figure, a kind of miniature circuit breaker, comprise housing 9, tripping 10, snap close 11 and above-mentioned indicating device, central shaft 12 rotations on described snap close 11 and the housing 9 cooperate, be hinged with the support seat 6 corresponding with snap close 11 on the described central shaft 12, described tripping 10 is hinged with supporting seat 6 upper ends, and described supports 6 upper end are provided with spacing cylinder 8, described indicating device is provided with the spacing draw-in groove 7 that matches with spacing cylinder 8, and described indicating device cooperates with housing 9 location by elasticity band plate 5.
At circuit breaker in closing course, drive tripping 10 rotations by handle, support seat 6 with tripping 10 interlocks, 8 pairs of spacing draw-in groove 7 inwalls of described spacing cylinder carry out the phase clamping to be promoted, make indicating device along the articulated section 2 the rotation, elasticity band plate 5 on the indicating device and the crooked deformation of housing 9 extruding, indicating device presents redness, shows " closure state "; , in the disconnection process, because tripping 10 is threaded off or handle resets, drive the spacing cylinder of supporting on the seat 68 thereupon and reset at circuit breaker, elasticity band plate 5 on the indicating device stretches deformation and discharges, make indicating device 2 reverse rotations along the articulated section, indicating device presents green, shows " off-state ".The design of elasticity band plate 5 and indicating device holding has changed the mode that existing indicating device and its back-moving spring design respectively, has the characteristics of easy to assembly, stable operation and long service life.
Embodiment should not be considered as the restriction to utility model, but any improvement of doing based on spirit of the present utility model, all should be within protection range of the present utility model.
