The below of the bottom surface front end of connection terminal is equipped with blocks the piece, block the upper end of piece with the bottom surface front end of connection terminal is connected, just block the upper end of piece and follow the connection terminal removes jointly, block piece bottom and wiring mouth below shell inner wall connection, block the bottom of piece with the hookup location of shell is in between the lower extreme and the regulation hole of wiring mouth.

Furthermore, the stop piece is the folding piece, just the bottom of folding piece with the junction of shell is in between the lower extreme and the regulation hole of wiring mouth.

Further, the folding piece is folded toward the inside of the housing.

Further, the material thickness of the folding sheet is smaller than that of the wire holder.

(III) compared with the prior art, has the following beneficial effects

The utility model has the advantages of simple structure, the modern design, the commonality is high, not only can stop the condition emergence of misconnection line completely and still do not occupy the installation space of circuit breaker, practices thrift the cost of manufacture, is fit for generally promoting.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 4-5, the present invention provides a technical solution: a miniature circuit breaker prevents mistake line ball component, including the wire holder 2, set up the screw 1 on the said wire holder 2, the screw 1 adopts the threaded connection with wire holder 2; the wire holder 2 and the screw 1 are arranged inside the shell 4, and the wire holder 2 moves up and down in the shell 4.

The below of the bottom surface front end of connection terminal 2 is equipped with blocks the piece, block the upper end of piece with the bottom surface front end of connection terminal 2 is connected, just the upper end that blocks the piece is followed connection terminal 2 moves jointly, block piece bottom and wiring mouth below 4 interior wall connection of shell, block the bottom of piece with the hookup location of shell 4 is in between the lower extreme and the regulation hole 6 of wiring mouth. The blocking piece is a folding piece 5, and the joint of the bottom end of the folding piece 5 and the shell 4 is positioned between the lower end of the wiring port and the adjusting hole 6; the folding piece 5 is folded toward the inside of the housing 4; the material thickness of the folding sheet 5 is smaller than that of the wire holder 2;

on many miniature circuit breakers, there is a hole under the wire holder 2, the adjusting hole 6 can be an adjusting hole for adjusting the overload characteristic of the bimetallic strip or an arc outlet for leading out the arc, the structure of the prior art will interfere with the hole, which results in the difficulty of adjusting the former or the difficulty of leading out the arc of the latter, and affects the product life, so that the prior structure can only be used in the miniature circuit breakers without overload and short-circuit protection, the miniature circuit breakers with overload and short-circuit protection cannot solve the problem of mis-wiring, in order to solve the technical problem, a foldable folding sheet 5 is arranged between the front end of the bottom surface of the wire holder 2 and the shell 4, the wire holder 2 can be moved together with the wire holder 2 at any position by the design of the folding sheet 5, so that the mis-wiring area of the circuit breaker interface wire is always in a closed state, therefore, the condition of wrong wiring is avoided, and after the folding sheet 5 is folded, the folding sheet cannot interfere with the adjusting hole 6, namely, the adjustment of the overload characteristic of the miniature circuit breaker is not influenced or the electric arc is not influenced to be smoothly led out from the cavity of the miniature circuit breaker.
