Description
Technical field
The present invention relates to a kind of leakage protecting plug.
Background technology
Existing leakage protecting plug comprises shell, two power pins, grounding pin, wiring board, ground connection fixed contact, grounding wafer, ground connection moving contact, two power supply contacts, two power supply fixed contacts, two power supply moving contacts and switch depression bar; Described ground connection moving contact is arranged on one end of grounding wafer, and the other end of described grounding wafer is installed in the circuit board, and ground connection fixed contact is electrically connected to grounding pin, and ground connection moving contact can contact and be electrically connected to ground connection fixed contact under the effect of switch depression bar.Grounding wafer is strip in the prior art; in order to reach good resilience effect; the end that grounding wafer is installed ground connection moving contact needs wing to rise; while making grounding wafer, need select the width of thinner sheet metal and grounding wafer to need smaller; its resilience effect of guarantee; but simultaneously also there will be the overcurrent of grounding wafer little, useful life is short and the problem such as unreliable of working, and can affect like this quality of leakage protecting plug and the reliability of work.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art and provide a kind of grounding wafer to have good resilience effect, the overcurrent of grounding wafer is large, long service life and safe and reliable leakage protecting plug.
In order to achieve the above object, the present invention is achieved in that it is a kind of leakage protecting plug, is characterized in that comprising:
Shell, two power pins and grounding pin, described two power pins and grounding pin are all plugged on shell;
Wiring board and ground connection fixed contact, described wiring board and ground connection fixed contact are installed in shell, and described ground connection fixed contact is electrically connected to above-mentioned grounding pin;
Grounding wafer and ground connection moving contact, between described grounding wafer and wiring board, there is resilience gap, one end of grounding wafer is arranged on above-mentioned wiring board and is electrically connected to, this end at grounding wafer is provided with crooked resilient portion, described ground connection moving contact is arranged on the other end of grounding wafer, and ground connection moving contact can coordinate and be electrically connected to above-mentioned ground connection fixed contact; And
Switch depression bar, described switch depression bar is located in above-mentioned shell and can axially moves up and down, thereby the outer formation of shell press section is stretched out in the end of switch depression bar, thereby the pushing block on switch depression bar coordinates promotion ground connection moving contact and ground connection fixed contact electrically contact or disconnect with the other end of grounding wafer.
The resilient portion of above-mentioned bending is down " U " shape.
The present invention's advantage is compared with prior art: grounding wafer has good resilience effect, and the overcurrent of grounding wafer is large, long service life and safe and reliable, the like this long service life of product and safe and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is stereogram of the present invention;
Fig. 3 is the stereogram of decapsidate upper cover in Fig. 2.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.At this, it should be noted that, for the explanation of these execution modes, be used for helping to understand the present invention, but do not form limitation of the invention.In addition,, in each execution mode of described the present invention, involved technical characterictic just can not interosculate as long as do not form each other conflict.
In the present invention describes, term " on " and orientation or the position relationship of the indication such as D score be based on orientation shown in the drawings or position relationship, be only the present invention for convenience of description rather than require the present invention with specific orientation structure and operation, therefore can not be interpreted as limitation of the present invention.
As shown in Figures 1 to 3, it is a kind of leakage protecting plug, comprising:
Grounding wafer 7, ground connection moving contact 6, two power supply contacts 10 and two power supply moving contacts, between described grounding wafer 7 and wiring board 4, there is resilience gap, one end of grounding wafer 7 is arranged on above-mentioned wiring board 4 and is electrically connected to, this end at grounding wafer 7 is provided with crooked resilient portion 71, the resilient portion 71 of described bending has guaranteed the resilience effect of grounding wafer 7, and ground connection moving contact 6 can be well electrically connected to ground connection fixed contact 8; During making, grounding wafer 7 can be selected thicker metal derby, and grounding wafer 7 also can be done widelyr, and the overcurrent that grounding wafer 7 bears is like this also larger, and long service life is safe and reliable; Described ground connection moving contact 6 is arranged on the other end of grounding wafer 7, and ground connection moving contact 6 can coordinate and be electrically connected to above-mentioned ground connection fixed contact 8; One end of described two power supply contacts 10 is arranged on wiring board 9 and is electrically connected to, and two power supply moving contacts are arranged on respectively the other end of two power supply contacts 10 separately, and two power supply moving contacts can coordinate and be electrically connected to power supply fixed contact 9; And
Switch depression bar 5, described switch depression bar 5 is located in above-mentioned shell 3 and can axially moves up and down, on switch depression bar 5, be arranged with back-moving spring, thereby the outer press section that forms of shell 3 is stretched out in the end of switch depression bar 5, thereby the pushing block 51 on switch depression bar 5 coordinates promotion ground connection with the other end of grounding wafer 7, moving contact 6 electrically contacts or disconnects with ground connection fixed contact 8, thereby switch depression bar 5 also coordinates promotion power supply with power supply contact 10, fixed contact 9 electrically contacts or disconnects with power supply moving contact.
During work, manually switch depression bar 5 is pressed in shell 3, now switch depression bar 5 promotes two power supply contacts 10, grounding wafer 7 resets under the effect of resilient portion 71, make ground connection moving contact 6 contact and be electrically connected to ground connection fixed contact 8, make power supply fixed contact 9 electrically contact and be electrically connected to power supply moving contact, electrical equipment switches on power; When there is leaky, switch depression bar 5 resets under the effect of back-moving spring, and two power supply contacts 10 reset; grounding wafer 7 is promoted by switch depression bar 5; ground connection moving contact 6 and ground connection fixed contact 8 are disconnected, power supply fixed contact 9 and power supply moving contact are disconnected, reach earth leakage protective object.In this programme, owing to there being resilient portion 71, the resilience of grounding wafer 7 is good, and the overcurrent of bearing is large.
In the present embodiment, the resilient portion 71 of above-mentioned bending is down " U " shape.
Below by reference to the accompanying drawings embodiments of the present invention are made to detailed description, but the present invention is not limited to described execution mode.For the ordinary skill in the art, in the situation that not departing from principle of the present invention and aim, these execution modes being carried out to multiple variation, modification, replacement and distortion still falls within protection scope of the present invention.
