Abstract
The utility model relates to a plug-in single-phase breaker including a breaker body where conductive pins extend from. The plug-in single-phase breaker is applied to a pedestal of a plug-in single-phase distribution box, and the pedestal of the plug-in single-phase distribution box is provided with a plug-in hole and a neck which correspond to the pins and a buckle. When the plug-in single-phase breaker is used, the breaker can be directly fixed by a way that the pins and the buckle are directed at the plug-in hole and the neck in the pedestal of the plug-in single-phase distribution box, the pins and the buckle are directly pushed in, and then the pins are fixed in the plug-in hole through screws. The design of the plug-in single-phase breaker facilitates installation, dismounting, replacement and maintenance of a distribution box, the installation, the dismounting, the replacement and the maintenance of the distribution box are easy and convenient, and connecting lines are reduced greatly to make the distribution box to be more beautiful.
Description
Technical field
The utility model relates to a kind of plug-in type single-phase circuit breaker.
Background technology
In supply line, distribution box is used for controlling power supply, in current single-phase indoor distribution box, be provided with a battery main switch, battery main switch is generally 2p circuit device, in the downstream of battery main switch, connects many circuit breakers, and one end inlet wire of these circuit breakers must parallel connection be linked into the output of battery main switch, but the aperture of battery main switch output is fixed, when one end inlet-wire parallel of circuit breaker accesses, because electric wire is many, can cause the problems such as wiring difficulty or loose contact.During practice of construction; electricians are for easy-to-connect; often by the inlet-wire parallel of 2 ~ 3 circuit breakers after single line; be linked into again the output of battery main switch; although the output of battery main switch access electric wire has reduced like this; but the maximum current that every wire can carry is limited, be parallel to the electric current that passes through that single line can increase this root line, electric current is excessive often can cause potential safety hazard.And zero terminal row of the necessary installation separately in distribution box the inside, zero terminal row will insulate with distribution box metal shell.Connecting line is too many, brings very large inconvenience and potential safety hazard to distribution box installation, maintenance.
Summary of the invention
The purpose of this utility model is to overcome the defect that prior art exists, and a kind of plug-in type single-phase circuit breaker is provided.
The technical scheme that realizes the utility model object is: a kind of plug-in type single-phase circuit breaker, comprise breaker body, and in described breaker body, extend the pin of conduction.
Further, described pin is the sheet metal that breaker body is extended conduction.
Further, described circuit breaker bottom is provided with buckle.
Further, described circuit breaker is divided into 1p circuit breaker, 1p+N circuit breaker and 2p circuit breaker, and buckle size, the length and width of described 1p circuit breaker and 1p+N circuit breaker bottom are identical, and the pin position of corresponding live wire is also identical.
The utlity model has positive effect: the utility model is used on plug-in type single-phase distribution box base, on plug-in type single-phase distribution box base, be provided with the jointing holes corresponding with pin and buckle and draw-in groove, during use, need only the pin of circuit breaker and buckle are aimed to jointing holes and the draw-in groove on plug-in type single-phase distribution box base, direct one pushes away, then with key screw pin, be fixed in jointing holes, circuit breaker has just directly been fixed, now in distribution box, only have total inlet wire and outlet, there is no other unnecessary connecting lines, and plug-in type single-phase distribution box base transverse ends is provided with into zero line plug terminal, when using 1p circuit breaker, also just no longer needing that zero terminal is installed has in addition arranged, the installation of distribution box is convenient in the design of plug-in type single-phase circuit breaker, dismounting, change and maintenance, very easy, safety, and a large amount of minimizings of connecting line, make distribution box integral body more attractive in appearance.And because buckle size, the length and width of 1p circuit breaker and 1p+N circuit breaker bottom are identical, the pin position of corresponding live wire is also identical, in the situation that not changing distribution box base, 1p circuit breaker and 1p+N circuit breaker can exchange at any time, very practical.
Accompanying drawing explanation
For content of the present utility model is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is 1p breaker structure schematic diagram of the present utility model.
Fig. 2 is 1p+N breaker structure schematic diagram of the present utility model.
