Abstract
The utility model relates to an insertion type signal-phase earth leakage protection switch. The insertion type signal-phase earth leakage protection switch comprises an earth leakage protection switch main body from which electroconductive pins extend, and one side of the bottom is provided with a buckle. The insertion type single-phase earth leakage protection switch is used on an insertion type single-phase distribution box base which is provided with insertion holes and a clamping groove corresponding to the pins and the buckle, in use, as long as the pins and the buckle of the earth leakage protection switch are aligned with the insertion holes and the clamping groove on the insertion type single-phase distribution box base, and is pushed directly, and then screws are used to fix the pins in the insertion holes, the earth leakage protection switch is directly fixed. The design of the insertion type single-phase earth leakage protection switch facilitates mounting, dismounting, replacement and maintenance of the distribution box, the insertion type single-phase earth leakage protection switch is very simple, convenient and safe, and connecting wires are greatly reduced, thereby enabling the overall distribution box to be beautiful.
Description
Technical field
The utility model relates to a kind of plug-in type single-phase earth leakage protection switch.
Background technology
In supply line, distribution box is for controlling power supply, be provided with a battery main switch in current single-phase indoor distribution box, battery main switch is generally the 2p circuit device, in the downstream of battery main switch, connects many circuit breakers, and an 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 the distribution box metal shell.Connecting line is too many, brings very large inconvenience and potential safety hazard to the 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 earth leakage protection switch is provided.
The technical scheme that realizes the utility model purpose is: a kind of plug-in type single-phase earth leakage protection switch, comprise the earth leakage circuit-breaker main body, and extend the pin of conduction on described earth leakage circuit-breaker main body.
Further, described pin is the sheet metal that the earth leakage circuit-breaker main body is extended conduction.
Further, described earth leakage circuit-breaker bottom is provided with buckle.
Further, the buckle of described earth leakage circuit-breaker is arranged on a side of bottom.
The utlity model has positive effect: the utility model is used on plug-in type single-phase distribution box base, be provided with the jointing holes corresponding with pin and buckle and draw-in groove on plug-in type single-phase distribution box base, need only during use the pin of earth leakage 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 the key screw pin, be fixed in jointing holes, earth leakage 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, the installation of distribution box is convenient in the design of plug-in type earth leakage 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.Again due to frequent grafting 1p circuit breaker and 1p+N circuit breaker on single-phase distribution box; so the buckle of earth leakage circuit-breaker bottom is located to a side; size, length and width are identical with the buckle on 1p circuit breaker, 1p+N circuit breaker; when plug-in type single-phase earth leakage protection switch patches on plug-in type single-phase distribution box base; take a draw-in groove and covered a draw-in groove that faces limit; in the situation that do not change the distribution box base; earth leakage circuit-breaker, 1p circuit breaker and 1p+N circuit breaker can exchange at any time, very practical.
The accompanying drawing explanation
For content of the present utility model more easily is expressly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein
Fig. 1 is structural representation of the present utility model.
Wherein: 32, pin, 33, buckle.
Embodiment
As shown in Figure 1; the utility model is a kind of plug-in type single-phase earth leakage protection switch, comprises the earth leakage circuit-breaker main body, extends the sheet metal pin 32 of conduction on the earth leakage circuit-breaker main body; the earth leakage circuit-breaker bottom is provided with buckle 33, and buckle 33 is arranged on a side of earth leakage circuit-breaker bottom.
The utility model is used on plug-in type single-phase distribution box base, be provided with jointing holes and the draw-in groove corresponding with pin 32 and buckle 33 on plug-in type single-phase distribution box base, need only during use the pin 32 of earth leakage circuit-breaker and buckle 33 are aimed to jointing holes and the draw-in groove on plug-in type single-phase distribution box bases, direct one pushes away, then with key screw pin 32, be fixed in jointing holes, earth leakage 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, the installation of distribution box is convenient in the design of plug-in type earth leakage 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.Again due to frequent grafting 1p circuit breaker and 1p+N circuit breaker on single-phase distribution box; so the buckle 33 of earth leakage circuit-breaker bottom is located to a side; size, length and width are identical with the buckle 33 on 1p circuit breaker, 1p+N circuit breaker; when plug-in type single-phase earth leakage protection switch patches on plug-in type single-phase distribution box base; take a draw-in groove and covered a draw-in groove that faces limit; in the situation that do not change the distribution box base; earth leakage circuit-breaker, 1p circuit breaker and 1p+N circuit breaker can exchange at any time, very practical.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
