Description
Technical field
It is exactly specifically to be related to a kind of external small-sized open circuit of electric energy meter the invention belongs to circuit breaker accessory mounting technique field
Device power taking sampling structure, can reduce the difficulty of circuit breaker internal power taking sampling structure installation.
Background technology
Low-voltage circuit breaker is divided into miniature circuit breaker, breaker of plastic casing and air-break by it using scope, be it is a kind of both
The manual division circuit of energy, can carry out the electrical equipment of automatic protection, it is functionally equivalent to molten to failures such as circuit overloads, short circuits again
The combination of disconnected device and relay, and it is latter in disjunction fault current as need not change parts, be applied widely.
Miniature circuit breaker product is used by multipole erection method in actual applications, with the development of intelligent grid, in order to
The various specific functions of miniature circuit breaker product are extended, user is frequently necessary on miniature circuit breaker assembled various plug-in annexes, had
A little plug-in annexes are needed from the power taking of miniature circuit breaker major loop, sampling.At present, the common plug-in annex of in the market is from small-sized open circuit
The power taking of device major loop, sampling mainly have two ways, and one kind is to connect miniature circuit breaker and annex with conductive devices from the outside, separately
One kind is the perforate on annex and breaker, and wire is passed through, connection annex and miniature circuit breaker.But both modes are all present
Defect, first way can increase the volume of miniature circuit breaker in external connection cabling, influence the outward appearance of product, and can shadow
Ring user's terminated line；The second way internally threading, manufacturability is poor, and it is unreliable to connect, and easily causes phase fault.
The content of the invention
The purpose of the present invention is complicated aiming at existing breaker power taking sampling structure, and connection safety is poor, meeting
Increase the technological deficiency of breaker volume there is provided a kind of external miniature circuit breaker power taking sampling structure of electric energy meter, it is simple in construction, even
Connect mode convenient, safe operation does not increase breaker volume, the outward appearance of product is not influenceed.Conductive reed draws in the middle of breaker
Go out, simple in construction, conductive reed is generally applicable up and down, dielectric property is good, electrically operated device right spelling or left can both be spelled.
Technical scheme
In order to realize above-mentioned technical purpose, the external miniature circuit breaker power taking sampling structure of a kind of electric energy meter that the present invention is designed, it
Including shell, the end of incoming cables of the shell or/and leading-out terminal are equipped with conductive reed, it is characterised in that：The conductive reed is mounted in
In the mounting groove of shell front side end or/and rear side end, elastic foot one end of the conductive reed and the electric-conductor of circuit breaker internal
Contact, the leads ends of conductive reed stretch out shell.
Further, pin one end of the conductive reed and electronic circuit board elastic connection, electronic circuit board are mounted in shell
Front side end or/and rear side end.
Beneficial effect
The external miniature circuit breaker power taking sampling structure of a kind of electric energy meter that the present invention is provided, simple in construction, connected mode is convenient, behaviour
Make safety, do not increase breaker volume, the outward appearance of product is not influenceed.Conductive reed is drawn in the middle of breaker, simple in construction, on
Lower conductive reed is generally applicable, and dielectric property is good, and electrically operated device right spelling or left can both be spelled.
