It is with one of the difference of above-mentioned embodiment, the breaker 6 in the embodiment is 2 pole breakers.It should be noted that the reality It is no substantially to apply breaker 6 and the fixed mechanism and electric connection mode of metering auxiliary device 7 and above-mentioned embodiment in example Difference, the quantity of electricity taking terminal or spring thimble only need to be accordingly adjusted according to the quantity of breaker power connecting column；This is 2 extremely disconnected The quantity of breaker power connecting column is 2 in the embodiment of road device, therefore the quantity of electricity taking terminal or spring thimble is also 2.

Incorporated by reference to referring to Figure 13 and Figure 14, Figure 14 is the installation of the intelligent breaker 500 of the embodiment of the utility model the 5th Schematic diagram.Intelligent breaker 500 includes breaker 6 and metering auxiliary device 7.Breaker 6 has end of incoming cables 60, end of incoming cables 60 In the top of breaker 6.Metering auxiliary device 7 is removably installed in the end of incoming cables 60 of breaker 6, and metering auxiliary device 7 wraps Include main body module 70, card accessory 71 and locking part 72.Main body module 70 by itself the first snap fit 701 and card accessory 71, Locking part 72 is fixed on the end of incoming cables 60 of breaker 6.Main body module 70 passes through electricity taking terminal or electricity-fetching module (being not illustrated in Figure 14) It is electrically connected with breaker 6.

Metering auxiliary device 7 also includes auxiliary housing 73, unlike the various embodiments described above, auxiliary housing 73 by itself Second snap fit 731 is fixed on main body module 70, rather than is directly fixed on the end of incoming cables 60 of breaker 6.This embodiment is applicable In the situation of neck deficiency on the end of incoming cables of breaker, auxiliary housing 73 can be used to supportive body module, protection wiring and make total Body is more attractive.

In addition, breaker either miniature circuit breaker, or breaker of plastic casing or frame circuit breaker, in different embodiments In, breaker installs the fixation of module additional with metering and is electrically connected with mode also without difference substantially, therefore the utility model is simultaneously It is not limited.

Metering auxiliary device and intelligent breaker of the present utility model based on breaker, connected by the machinery of innovative design Mode is connect and be electrically connected with, can be completed at lower cost and conveniently and efficiently on the basis of traditional breaker and distribution box The add-assembly of Intellectualized metering module, and space-consuming is smaller, fixed, is very suitable for a large amount of of intelligent breaker and pushes away Wide application.

The utility model is in terms of mechanical connecting structure, by the card for measuring the buckle and embedded breaker that install additional in module Accessory and locking part so that metering auxiliary device is combined into one with conventional circuit breaker.The utility model is solving to measure auxiliary In terms of the power supply of device, using two class ways to take power：A kind of is with the inserted sheet on circuit module, is directly connected to breaker and connects power port Interior binding post lock；Another kind is to use spring ejector pin connector, by the intraoral binding post screw of breaker power taking and circuit mould Shell fragment on block is electrically connected with.The utility model is in the embodiment using spring ejector pin connector, except aforementioned techniques are imitated Outside fruit, the transformation repacking that do not have a power failure of intelligent breaker can also be realized.

The utility model is described by above-mentioned related embodiment, but above-described embodiment is only to implement the utility model Example.It must be noted that the embodiment disclosed is not limiting as the scope of the utility model.On the contrary, this is not being departed from Change, combination and the retouching made in the spirit and scope of utility model, belong to scope of patent protection of the present utility model.
