Description

A kind of miniature circuit breaker remote control operation mechanism

Technical field

The invention belongs to small low-voltage construction of switch design field, be specifically related to a kind of miniature circuit breaker remote control operation mechanism.

Background technology

Small low-voltage switch (for example small low-voltage switch of C45 type or DZ47 type) is although in extensive use and the supply line of family, because the restriction of its small volume and self structure is difficult to install additional the electrodynamic type close/open machine at present.The small low-voltage switch that has individually electronic divide-shut brake function is also arranged in the market, its structure has following two kinds: (1) is built in electronic close/open machine in the small low-voltage switch case, also namely with the small low-voltage switch in binding post, operating mechanism, overload flow protection mechanism be arranged in the same housing, its structure is comparatively complicated, easily breaks down; In addition, because the market of present electronic opening and closing type small low-voltage switch is less, enterprise produces the electronic opening and closing type small low-voltage switch of this integral type, design brand-new structure, mould and production procedure, drops into larger; (2) external on small low-voltage switch case outer wall electronic close/open machine, the disclosed air switch controller of patent documentation CN201302949Y for example; The shortcoming of this structure is that profile is ugly, in addition owing to adopting the guide tracked installation of DIN on the small low-voltage switch main flow of C45 type or DZ47 type, the standardization of the installing space of its reservation generally is difficult to satisfy the required space requirement that takies of this outlet structure.

In addition, the guide tracked installation of DIN is the common a kind of mounting means of industrial electric element, and has formed at the international level certain standard, supports the electric component of this standard can be stuck in easily on the guide rail and need not to be screwed, dismounting and safeguard also very convenient.The width of common guide rail is 35mm, some novel air switches such as DZ47-63 series, and contactor CJX1,2,8 series, circuit breaker DZ-108 series, miniature relay, portion of time relay set have all adopted this standard.

Summary of the invention

The purpose of this invention is to provide a kind of profile comparatively attractive in appearance, install comparatively convenient, use comparatively easily miniature circuit breaker remote control operation mechanism.

The technical scheme that realizes the object of the invention is: a kind of miniature circuit breaker remote control operation mechanism is characterized in that: comprise insulation crust, stretch out dialling handle and being used for driving and dialling the motor drive mechanism that handle is back and forth stirred of insulation crust; Motor drive mechanism comprises the linkage gear assembly of motor with output gear, thumb wheel and interlock output gear and thumb wheel, and described motor drives the thumb wheel reciprocating rotation by the linkage gear assembly, and and then drive by thumb wheel and to dial handle and back and forth stir; Described linkage gear assembly comprises master gear and the pinion of coaxial setting, master gear and thumb wheel are the circumference gears that is equipped with the gear teeth on the whole excircle, pinion is to only have the partial arc place just to be provided with the sector gear of the gear teeth on the whole excircle, master gear and output gear engagement arrange, and pinion and thumb wheel engagement arrange.

In the such scheme, the linkage gear assembly also comprises and master gear, the coaxial setting of pinion, and is used for driving the bidirectional clutch of master gear and pinion.

The present invention is made of one separately part in the remote control operation mechanism miniature circuit breaker, in use, can install side by side with miniature circuit breaker, utilize motor drive mechanism to drive group handle and back and forth stir, recycling is dialled handle and is driven the manual trigger piece reciprocating rotation of divide-shut brake of miniature circuit breaker to realize the Long-distance Control of divide-shut brake.In addition, in order to simplify installation, also be provided with the guide tracked section that clamps of DIN at insulation crust.In concrete practice, can make insulation crust with the housing of adaptive small low-voltage Switch main body onesize, it can be snapped fitted on the external DIN guide rail side by side with the small low-voltage Switch main body, thereby have advantages of good looking appearance, installation facility, easy to use.Because the present invention and miniature circuit breaker split arrange, do not affect the manufacturing of original miniature circuit breaker in addition, concerning enterprise, can obtain the present invention by outsourcing or the mode of making separately, thereby effectively reduce fund input, reduce integrated cost.

Embodiment

(embodiment 1)

Fig. 1 to Fig. 3 has shown the first embodiment of the present invention, and wherein Fig. 1 is a kind of perspective view of the first structure of the present invention; A kind of perspective view of Fig. 2 when to be operating mechanism shown in Figure 1 from another angle observe; Fig. 3 is a kind of decomposing schematic representation of operating mechanism shown in Figure 1.

The present embodiment is a kind of miniature circuit breaker remote control operation mechanism, see Fig. 1 to shown in Figure 3, this operating mechanism 2 comprises insulation crust 3, stretch out dialling handle 4, being used for driving and dialling the motor drive mechanism 5 that handle back and forth stirs and be arranged on the guide tracked section 6 that clamps of DIN on the insulation crust of insulation crust.

Motor drive mechanism in the present embodiment comprises the linkage gear assembly 54 of motor 52, thumb wheel 53 and interlock output gear and thumb wheel with output gear 51, described motor drives the thumb wheel reciprocating rotation by the linkage gear assembly, and and then drive to dial the handle reciprocating rotation by thumb wheel, dial handle owing to being fixedly installed with manually trigger piece is relative, carry out the divide-shut brake action thereby drive manual trigger piece.Be fixed with plate 55 on the described thumb wheel, the outboard end of this plate stretches out insulation crust as dialling handle.
