Cross the RCCB used on the market to power off not in time with the presence of part, reliability is not high, and tripping mechanism linkage is bad
Problem.
The content of the invention
The utility model is solution the deficiencies in the prior art, there is provided one kind power-off is timely, electric leakage possibility is small,
The tripping mechanism for the RCCB that reliability is high and usability is high.
To achieve the above object, a kind of tripping mechanism of RCCB, including a connecting rod, tripping mechanism also include threading off
Part and tripping coil, dropout part are made up of a connecting portion with slipping part, and connecting portion forms "u"-shaped groove, connecting rod one end at dropout part
It is arranged in the "u"-shaped groove, its slipping part, which is connected with tripping coil and formed therewith, to be connected.
The tripping mechanism of above-mentioned RCCB, the tripping mechanism pass through between connecting rod dropout part and tripping coil
Contact produces linkage, and the excessive situation of leakage current is worked as at tripping mechanism and is occurred, and tripping coil is an electromagnetic induction device, when
The device can produce suction or pulling force in the case of having electricity, so that dropout part moves, because connecting rod one end is connected with operating mechanism,
The other end is connected with dropout part connecting portion, and dropout part slipping part moves to tripping coil side, and then drives and be connected with dropout part
Portion is moved, so that operating mechanism tripping, i.e. RCCB are threaded off, the dropout part in the tripping mechanism is commonly threaded off to integrate
The intergrant that part and pull bar are formed, while the function of specific dropout part and pull bar, its be advantageous in that will not due to dropout part with
Pull bar links or contacts the bad situation for occurring threading off not in time, realizes the greater compactness of purpose of linkage, and the dropout is simple rapidly,
Linkage is reliable；And then solving RCCB power-off not in time, reliability is not high, and tripping mechanism links the problem of slower；It is logical
The reliability that the restriction to dropout part shape can ensure to thread off is crossed, causes to be not in that connection contact is improper, and occurring linking does not connect
The problem of passing through or taking off mouth not in time.
The utility model is further arranged to, and connecting rod is arranged above the connecting portion at dropout part, and bending passes through downwards one
Bending section is simultaneously extended in the "u"-shaped groove at connecting portion, is arranged at "u"-shaped groove inside connecting rod and is connected with "u"-shaped groove composition.
The tripping mechanism of above-mentioned RCCB, it is described to ensure that dropout part is certifiable under trip status by the setting
Drivening rod activity, furthermore the reliability threaded off by connecting rod with pneumatic operating mechanism.
The utility model is further arranged to, and is provided with a sliding movable part at tripping coil, the slipping part at dropout part
Radial displacement can be made in the sliding movable part.
The tripping mechanism of above-mentioned RCCB, the slipping part at the dropout part is placed in tripping coil, at dropout part
Connecting portion in be provided with connecting rod and coupled, the connecting rod other end is connected with operating mechanism, the sliding activity at tripping coil
The operating range of slipping part is distance needed for tripping mechanism is threaded off at portion.
The utility model is further arranged to, and slipping part one end at tripping coil with being connected at dropout part, the other end and company
Socket part end is connected, and the connecting portion is oppositely extending in connecting portion end, and the extension and slipping part are in 90 degree of angles, the company
The connecting rod side that socket part is extended in "u"-shaped groove, furthermore 90 degree of turning extends to connecting rod opposite side and bent upwards, furthermore to even
The bending of 90 degree of bar side, the kink bending length are located at "u"-shaped groove more than connecting rod and are engaged distance.
The tripping mechanism of above-mentioned RCCB, the described structure link institute between dropout part and connecting rod, tripping coil
If structure, the alternative former dropout part of the structure and pull bar, linked with connecting rod, tripping coil, this is rational in infrastructure reliable.
The utility model is further arranged to, and dropout part is that a sheet metal coiling forms.
The tripping mechanism of above-mentioned RCCB, the dropout part is that a sheet metal coiling forms, due to dropout part shape
Restriction, according to spliced dropout part, then its intensity is difficult to ensure that, using being integrally formed its tedious process, and is not easy to be formed,
And sheet metal is used, because dropout part is sheet metal, to cause to be placed in tripping coil around into the problem of above-mentioned can be avoided to occur
Splicing trace be present in interior " annulus ".
