Description
Technical field
The invention belongs to the breaker structure design field, be specifically related to a kind of miniature circuit breaker with indicating device.
Background technology
Present common miniature circuit breaker contact shows it is to rely on the words identification that is arranged on the operating grip root to show contact state of living in, described words identification generally comprises two kinds of different signs, when operating grip rotates, corresponding sign just can be seen intuitively, but this display packing traditionally can not satisfy the contact indication requirement that is applicable to the small-sized short-circuiting device of isolating usefulness.Because though under normal circumstances operating grip and explicit identification can be consistent with contact state, but when contact generation melting welding, though operating grip can rotate, contact can not rotate thereupon, so display packing just can't correctly show contact state traditionally.
Summary of the invention
Even the purpose of this invention is to provide a kind of when contact generation melting welding also correct a kind of miniature circuit breaker of indicating operating status with indicating device.
The technical scheme that realizes the object of the invention is: a kind of miniature circuit breaker with indicating device comprises housing, is articulated in operating grip and operating mechanism on the housing; Described operating mechanism comprises the contact indication piece that is provided with the indicator, is being provided with display window with corresponding position, indicator on the described housing.
The tripping that described operating mechanism also comprises contact, contact supporter, articulate with the contact indication piece, the snap close that articulates with the contact indication piece, contact pressure torsion spring, disjunction spring and fore shaft torsion spring fast; Described contact indication piece and contact supporter are set on the rotating shaft and under the elastic force effect of contact pressure torsion spring and are combined together.
Be provided with the connecting rod that is used for linking each other between described operating grip and the operating mechanism, described connecting rod one end and operating grip are rotationally connected, and the other end and operating mechanism are rotationally connected.
One end of described connecting rod is provided with first articulated section, another disconnected second articulated section that is provided with; Described operating grip is provided with the axis hole that matches with first articulated section, and described tripping is provided with the axis hole that matches with second articulated section.
Indicator on the described contact indication piece comprises first indicator and second indicator of adjacent setting.
The present invention has positive effect: moving contact is contained on the contact supporter, contact indication piece and contact supporter are sleeved on axle and form a rotating shaft, answer on contact indication piece and the contact supporter with contact pressure torsion spring fitting together tightly, so the contact indication piece is consistent with the operating state of moving contact all the time; In the practice, can on the contact indication piece, coat red, green color mark, can be like clockwork show the operating state of contact with red, green color, provide safety guarantee maintenance and use at the display window place of housing.

Embodiment
(embodiment 1)
Fig. 1 to Fig. 9 has shown a kind of embodiment of the present invention, and wherein Fig. 1 is a kind of perspective view of the present invention; Fig. 2 is the decomposition texture schematic diagram with miniature circuit breaker of indicating device shown in Figure 1; Fig. 3 is a kind of perspective view of connecting rod in the miniature circuit breaker with indicating device shown in Figure 1; Fig. 4 is a kind of perspective view of operating mechanism in the miniature circuit breaker with indicating device shown in Figure 1; The perspective view that Fig. 5 is an operating mechanism shown in Figure 4 when another angle is observed; Fig. 6 is a kind of perspective view of operating grip in the miniature circuit breaker with indicating device shown in Figure 1; Fig. 7 is a kind of perspective view of tripping in the miniature circuit breaker with indicating device shown in Figure 1; Fig. 8 is that the miniature circuit breaker with indicating device shown in Figure 1 is in the structural representation when opening a way; Fig. 9 is that the miniature circuit breaker with indicating device shown in Figure 1 is in the structural representation when closed circuit.
Present embodiment is a kind of miniature circuit breaker with indicating device, sees Fig. 1 to Fig. 7, comprises housing 1, is articulated in operating grip 2 and operating mechanism 3 on the housing 1; The tripping 34 that described operating mechanism 3 comprises the contact indication piece 31 that is provided with indicator 311, contact 32, contact supporter 33, articulate with contact indication piece 31, the snap close 35 that articulates with contact indication piece 31, contact pressure torsion spring 36, disjunction spring 37 and fore shaft torsion spring 38 fast; Described contact indication piece 31 is set on the rotating shaft 5 and under the elastic force effect of contact pressure torsion spring 36 with contact supporter 33 and is combined together.Be provided with display window 11 with 311 corresponding positions, indicator on the described housing 1.Indicator 311 on the described contact indication piece comprises first indicator 3111 and second indicator 3112 of adjacent setting.First indicator 3111 in the present embodiment is coated the mark of red, green two kinds of different colors as different conditions respectively with second indicator 3112.
See Fig. 1 to Fig. 3, be provided with the connecting rod 4 that is used for linking each other between described operating grip 2 and the operating mechanism 3, described connecting rod 4 one ends and operating grip 2 are rotationally connected, and the other end and operating mechanism 3 are rotationally connected.One end of described connecting rod 4 is provided with first articulated section 41, another disconnected second articulated section 42 that is provided with; Described operating grip 2 is provided with the axis hole 21 that matches with first articulated section 41, and described tripping 34 is provided with the axis hole 341 that matches with second articulated section 42.In actual applications, also can adopt other pivot joint mode, only described connecting rod 4 one ends and operating grip 2 are rotationally connected, the other end and operating mechanism 3 are rotationally connected and get final product.
Fig. 8 and Fig. 9 have shown two kinds of operating states of present embodiment, a kind of when another kind transforms from these two kinds of operating states, only need pull operating grip 2 rotates to an angle, thereby can turn an angle by the indication piece 31 that connecting rod semi-finals system drives in the tripping 34 drive operating mechanisms 3, finally indicate correct operating state.
See Fig. 6, traditional display packing is at operating grip 2 both sides roots 22 places words identification to be set, rotation along with operating grip 2, the words identification of corresponding state exposes, and can observe intuitively, but its shortcoming also clearly, in case melting welding takes place in contact 32, because contact 32 is motionless, operating grip 2 still can rotate, so the words identification of this moment can not keep consistency with contact 32 states again; And unique texture design of the present invention can guarantee effectively that then operating grip 2, contact indication piece 31 and contact 32 keep consistency, and provides safety guarantee to maintenance and use.
