Abstract

The utility model discloses a breaker. The breaker comprises a shell, two ends of the shell are provided with screw installing holes, two sides of the shell are provided with two opposite outer wall surfaces, and the two outer wall surfaces are respectively provided with two dovetail grooves and two dovetail sliding tables matched with the dovetail grooves. When breakers are installed, adjacent breakers are connected via the dovetail grooves and the dovetail sliding tables, the installation and the dismounting can be conveniently performed, the breakers are not all needed to be unloaded, the connection is very reliable, and the numbers of the dovetail grooves and the dovetail sliding tables are both set as two so that the reliability of the connection is improved and the structure is simple.

Description

Circuit breaker

Technical field

The utility model relates to a kind of electric equipment, relates in particular to a kind of for cutting off or the circuit breaker of connection circuit.

Background technology

Circuit breaker is for cutting off or being communicated with road, and it is compared with switch, and inside is provided with anti-short circuit and current-limiting apparatus, and fail safe is higher, therefore in building circuit and various electric equipment, is widely used.On the bottom surface of existing circuit breaker, be provided with hanging groove or dovetail groove, in use, the support made from bonding jumper, through this dovetail groove or hook, is suspended on circuit breaker in electric box.If dovetail groove is set in its bottom, if while dismantling so one of them circuit breaker, all circuit breakers must be pulled down, middle circuit breaker could be extracted out, and adopt hook, circuit breaker installation reliability is not high, has limited its applicable situation.

Utility model content

For solving the deficiencies in the prior art, the utility model provides a kind of circuit breaker, and easy accessibility connects reliable.

For achieving the above object, circuit breaker of the present utility model, comprises that two ends are provided with the housing of screw mounting hole, and housing both sides have two relative outside wall surface, the dovetail slide unit that is respectively equipped with dovetail groove and coordinates with this dovetail groove in these two outside wall surface.

As to restriction of the present utility model, the quantity of the dovetail groove being provided with in outside wall surface and dovetail slide unit is two.

Adopt technique scheme, its beneficial effect is as follows: when circuit breaker is installed, between adjacent circuit breaker, by dovetail groove, be connected with dovetail slide unit, can carry out easily installing/dismounting, do not need circuit breaker all to unload, connection is simultaneously very reliable, and the quantity of dovetail groove and dovetail slide unit is made as two, can increase the reliability connecting, structure is simpler simultaneously.

Accompanying drawing explanation

Below in conjunction with the drawings and the specific embodiments, the utility model is done further to describe in detail:

Fig. 1 is the structural representation of circuit breaker of the present utility model;

Fig. 2 is the vertical view of circuit breaker of the present utility model;

Fig. 3 is the assembled state schematic diagram of circuit breaker of the present utility model.

In figure: 1, housing; 2, screw mounting hole; 3, dovetail groove; 4, dovetail slide unit.

Embodiment

As shown in Figure 1 to Figure 3, the utility model discloses a kind of circuit breaker, its housing 1 is made of plastics, roughly be rectangular-shaped, at the two ends of housing 1, be provided with screw mounting hole 2, the thickness direction both sides of housing 1 have two relative outside wall surface, in these two outside wall surface, are respectively equipped with dovetail groove 3 and dovetail slide unit 4, and dovetail groove 3 matches with dovetail slide unit 4.Dovetail groove 3 is provided with one with dovetail slide unit 4, and its quantity also can all be set to two.When assembling, dovetail groove 3 and the dovetail slide unit 4 of adjacent circuit breaker match, and by the size of dovetail groove 3 and dovetail slide unit 4 is set, make both combinations tight, are difficult for getting loose.Screw mounting hole 2 on outermost circuit breaker is arranged in electric box with screw respectively, can complete the installation of circuit breaker.If dismounting certain circuit breaker wherein only need be extracted out.

Claims

1. a circuit breaker, comprises that two ends are provided with the housing of screw mounting hole, and housing both sides have two relative outside wall surface, it is characterized in that: the dovetail slide unit that is respectively equipped with dovetail groove and coordinates with this dovetail groove in these two outside wall surface.

2. circuit breaker according to claim 1, is characterized in that: the quantity of the dovetail groove being provided with in outside wall surface and dovetail slide unit is two.
