Description
Technical field
The invention belongs to breaker technical field more particularly to a kind of leakage circuit breakers.
Background technology
Leakage circuit breakers (residual current circuit-breaker):Leakage current is more than predetermined value in circuit
When can auto-action switch.Common leakage circuit breakers is divided into two class of voltage-type and current mode, and current mode is divided into as electromagnetism
Two kinds of type and electron type.Electron type breaker such as notification number is CN 104201067A currently on the market, and patent name is：It is a kind of
The shortcomings that breaker connection system, the product, has：
Electron type breaker magnet ring (current transformer) is mounted side by side on the side of breaker, either level-one or four
Pole will be connect by conducting wire with magnet ring per pole, is resulted in product in this way and is leaked electricity sufficiently bulky shared by part, product is using
When installation space it is very big；
Since every pole of multipole will access conducting wire to magnet ring, then just needing more growing from magnet ring more long-range guided missile line length, make
Increase at the material cost of product, and the connection resistance of conducting wire is made to become larger, the internal temperature rise for also resulting in product is higher；
Electric leakage part line plate is connect with main traverse line needs to carry out artificial spot-welded, the time-consuming load for also increasing main traverse line
Leakage resistance makes product Wen Sheng get higher；
The grafting that artificial progress magnet ring and main traverse line are needed in assembly, when using hard conducting wire, due to the access of every pole
Conductor length differs, so needing to make various types of conducting wires, difficulty is larger in producing assembly technology, production efficiency compared with
It is low；
It need to be filled in manually per polar conductor when assembled wiring at present in the market, also need to add protective cover, time-consuming, inefficiency；
Test loop in the market is protected without double breaking points, and reverse wiring is by can burn out resistance when test button.
Invention content
Purpose of the present invention is to be directed to, existing circuit breaker design is unreasonable to cause that shape is big, cost is big, resistance is big, inside temperature
The defects of raising, low production efficiency, provides a kind of relatively small leakage circuit breakers of shape, which is set due to special construction
Meter is so that the opposite reduction of breaker resistance, the internal production installation effectiveness that is also relatively small, greatly improving product that heats up, section
About cost.
The present invention is achieved by the following technical solution：
Leakage circuit breakers, including MCB modules and leakage, breaking module further include total outlet end module, leakage, breaking mould
Block middle magnetic ring is mounted in total outlet end module, directly passes through wiring between the total leading-out terminal of leading-out terminal and breaker of MCB modules
Plate connects, and terminal plate is arranged across magnet ring.
The magnet ring is hollow cyclic structure, and the length of horizontal direction is greater than short transverse.
The leakage, breaking module and MCB modules is two mutually independent modules, and the two is assembled structure, electric leakage
It is fixed by pin or rivet between turn-off module and MCB modules.
Described terminal plate one end is connected in total outlet end module, and the terminal plate other end extends to outside total outlet end module
Portion, terminal plate extend to total leading-out terminal module-external one end and are inserted into MCB modules, and terminal plate is pressed on MCB by screw
In module.
The terminal plate is connected to total outlet end module one end side screens with outward extension.
The one side that the terminal plate is inserted into one end in MCB modules is equipped with recessed striped groove.
The terminal plate is integral type one-pass molding structure.
Beneficial effects of the present invention：The present invention uses fixed width (18mm) Modular design, protects electric leakage part either 2
Pole or 4 extremely width immobilize, and overall dimension can obtain larger reduction, to eliminate material, reduce
Production cost；Electric leakage magnet ring is changed to long-elliptical by original circle；Electric leakage main traverse line originally adds terminal plate to be changed to directly
It with the form of terminal plate, saves welding, prick the processes such as magnet ring, product testing circuit is contacted by conventional one-point type, is updated to double
Breakpoint formula, duplicate protection.Due to improving product overall performance, improves problem of temperature rise, reduce small product size, improve the work of product
Reliability and stability.Product structure is simple, small, easy to produce, and internal temperature rise is secure, the equal bands of N of all plus product every
From function, the wiring board of the 2 extremely above products takes multiphase current-taking function, and stable and reliable in work, use is safer.

Embodiment
Leakage circuit breakers as Figure 1-Figure 5, including (MCB modules are the main part of breaker to MCB modules 1, are short
Road tripping mechanism, the mechanism do not do for the prior art and excessively elaborate herein) and (the leakage, breaking module of leakage, breaking module 2
Structure is essentially identical with traditional leakage circuit breakers modular structure principle, does not also do excessive elaboration herein, and difference is exactly magnetic
The structure and installation site of ring are different), further include total outlet end module 3, (magnet ring is exactly 2 middle magnetic ring 21 of leakage, breaking module
Current transformer) it is mounted in total outlet end module, it is straight between the total outlet end module 3 of leading-out terminal 11 and breaker of MCB modules
The connection of terminal plate 4 was connected, and terminal plate 4 is arranged across magnet ring 21.The magnet ring 21 is hollow cyclic structure, and horizontal
The length in direction is greater than short transverse, as oval or likeness in form elliptical shape structure.The leakage, breaking module 2 and MCB
Module 1 is two mutually independent modules, and the two is assembled structure, passes through pin between leakage, breaking module 2 and MCB modules 1
Nail or rivet are fixed.Described 4 one end of terminal plate is connected in total outlet end module 3, and 4 other end of terminal plate extends to total outlet
Outside end module 3, terminal plate 4 extends to 3 outside one end of total outlet end module and is inserted into MCB modules 1, by screw by wiring
Plate 4 is pressed in MCB modules 1.The terminal plate 4 is connected to total 3 one end side of outlet end module card with outward extension
