Abstract
The utility model discloses a small circuit breaker, wherein, a circuit breaker and a base of which are an inserting and dialing type. The utility model is mainly composed of the circuit breaker and the base. The utility model is characterized in that connecting plates at a wire inlet end and a wire outlet end in the circuit breaker are projected out of the bottom of an outer shell and form a pin shape; electric conduction clamps at a wire inlet end and a wire outlet end in the base matched with the connecting plates form a socket shape. The utility model has the advantages of artful design, reasonable structure, complete protection functions, excellent performances and safe operation. The utility model has the functions of a small circuit breaker, an isolation switch and a fuse. In a low-voltage terminal power distribution system, the isolation switch and the fuse can be cancelled, which reduces the volume of a distributing box.
Description
The utility model relates to a kind of low-voltage electrical apparatus that is used for low-voltage distribution system, particularly relates to the miniature circuit breaker that a kind of circuit breaker and base are pulling and inserting type.
The popular in the market small-sized residual current circuit breaker or the mounting means of miniature circuit breaker adopt screw, pressing plate or guide rail, electric connecting mode is that lead or busbar are linked to each other with the junction block or the pressing plate seat of device at small-sized residual current circuit breaker or miniature circuit breaker, be screwed connection, it installs with being electrically connected all is fixed, and installation, maintenance is not too convenient.In addition, the dynamic and static contact of small-sized residual current circuit breaker or miniature circuit breaker all is installed on enclosure, with regard to small-sized residual current circuit breaker, even when contact is in disconnected position, people also can't see tangible cut-off point, this does not just meet the safety requirements of power supply department, and electrical repair personnel's safety is had certain hidden danger.
The purpose of this utility model provides and a kind ofly can effectively overcome above-mentioned defective, and installation, maintenance is the pulling and inserting type miniature circuit breaker easily.
The technical solution of the utility model is, a kind of pulling and inserting type miniature circuit breaker, mainly be made up of circuit breaker and base, its characteristics are: the connecting plate of the turnover line end in the circuit breaker protrudes in outer casing bottom and is the pin shape, and the conductive clip of the turnover line end in the base that matches is receptacle-shaped.
Owing to adopt such scheme; be not difficult to draw as drawing a conclusion: the utility model is skillfully constructed; rational in infrastructure, can integrate the function of miniature circuit breaker, isolating switch and fuse, it is complete to have a defencive function; superior performance; safe and reliable, in low pressure terminal distribution system, can save isolating switch and fuse; dwindled the volume of distribution box, the tool practical and popularizing value.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the right view of Fig. 1.
Referring to Fig. 1, the upper end of circuit breaker 2 of the present utility model is provided with operating grip 12, and the connecting plate 8 of its turnover line end protrudes in the plastic casing bottom and is the pin shape.The turnover line end of the base of being made by engineering plastics 1 is equipped with the conductive clip 6 that copper coin is made, and is receptacle-shaped with the conductive clip 6 of connecting plate 8 couplings, O shape spring 7 is housed, to increase the elastic force of conductive clip 6 on the conductive clip 6.Junction block 4 is equipped with in the outside of conductive clip 6, is connected with joint cover 3 between conductive clip 6 and the junction block 4, with screw 5 conductive clip 6 is fixed on the base 1.The connecting plate 8 that is the pin shape is designed to have only the identification direction could insert conductive clip 6.Referring to Fig. 2, protective cover 11 is stuck in the two ends of base 1, and conductive component is not exposed.Referring to Fig. 3, clamp 9 is equipped with in the bottom of base 1, and a cylinder-shaped compression spring 10 is housed between clamp and the base 1.
Of the present utility model to install and use step as follows: base is stuck on the TH35 mounting rail that meets the JB6525-92 standard, the turnover line of phase line is connected in the junction block that the base upper and lower side indicates " L ", screw terminal screw, the turnover line of the neutral line is connected in the junction block that the base upper and lower side indicates " N ", screw terminal screw, again handle is in " branch " position, the connecting plate that is the pin shape is inserted to be in the conductive clip of receptacle-shaped, handle is pushed into " closing " position, gets final product normal power supply.
The utility model is when circuit or power consumption equipment need overhaul, the operating grip of miniature circuit breaker is pulled to " branch " position, again circuit breaker is extracted from base, can have obvious cut-off point, play the insulating power supply effect, can overhaul circuit or power consumption equipment safely, Awaiting Overhaul finishes, circuit breaker is inserted base again, push to operating grip, restore electricity.
Claims (2)
1, a kind of pulling and inserting type miniature circuit breaker mainly is made up of circuit breaker and base, it is characterized in that: the connecting plate of the turnover line end in the circuit breaker protrudes in outer casing bottom and is the pin shape, and the conductive clip of the turnover line end in the base that matches is receptacle-shaped.
2, by the described a kind of pulling and inserting type miniature circuit breaker of claim 1, it is characterized in that: O shape spring is housed on the conductive clip.
