The statement in the locations of structures such as directions such as upper and lower, top, bottom is not absolute, opposite.When in all parts such as figure
When shown arrangement, the statement of these directions is appropriate, but in figure when the position change of all parts, and the statement of these directions is also corresponding
Change.
Referring first to Fig. 1 to Fig. 6, a kind of leakage protecting plug of preferred embodiment according to the present invention is shown.The leakage
Electric protection plug includes the shell being made of upper cover 3 and pedestal 1, is provided with cartridge assemblies 2 and wire component 4 in shell.Machine core
Component 2 includes printed wiring board 23, the detection components that are set in printed wiring board 23 and trip assembley therefor, input plug piece 21,
22 and output moving contact arm be coupled respectively with cartridge assemblies 2.Wherein, as shown in Figure 3 and Figure 4, input plug piece 21,22 can
Support is fixed on plug plate rack 24, and welding ends 21A, 22A of input plug piece 21,22 may pass through printed wiring board 23
On pad hole 23B, 23A and be welded in printed wiring board 23, be achieved in reliable electrically connected.Wire component 4 can be with
With electric wire and the line card coated, line card is fixed by the bayonet being arranged in upper cover 3 and pedestal 1, to improve the anti-of product
Bending property.In addition, may be provided with reset button, test button between upper cover 3 and cartridge assemblies 2.When the intracorporal each component of shell
After assembly, the two can be positioned by respectively arranged clamping part in upper cover 3 and pedestal 1, and for example, by screw 11
Secure component the two is fixed.
Design according to the present invention is also provided with the inserted sheet set being set on pedestal 1 in leakage protecting plug, and should
Inserted sheet set is made of insulating temperature resistant meterial.Advantageously, inserted sheet set includes build-up member corresponding with the quantity of input plug piece,
Such as in Fig. 5 and embodiment shown in fig. 6, inserted sheet set 10 is made of integrally formed two build-up members 101,102, and is filled
