Abstract
The invention provides a power plug with an electric leakage protection function. The power plug comprises a shell body and a machine core assembly (10) which is arranged in the shell body. The machine core assembly (10) comprises a moving contact frame (102) which is installed on a circuit board (101) to support a moving contact, and a release assembly which coordinately acts with the moving contact. The power plug is characterized in that the machine core assembly (10) further comprises an indicating assembly, wherein the indicating assembly comprises an indicating lamp (111), a light guide sheet (5) and a reflective member which is arranged between the indicating lamp (111) and the light guide sheet (5) in an inclination way; and pins of the indicating lamp are bent at a certain angle and are welded on the circuit board (101). With arrangement of the indicating assembly in the power plug, the position of the indicating lamp relative to the light guide sheet can be relatively flexible rather than be arranged exactly below the light guide sheet, thereby optimizing layout of all parts and components.
Description
Technical field
The present invention relates to a kind of attaching plug, particularly relate to a kind of attaching plug with creepage protection function.
Background technology
In daily life, the use of attaching plug is very general; to leak electricity the damage that power consumption equipment is caused to effectively avoid the power supply output line because of plug; and because of the electric shock injury caused the person of leaking electricity; developed many attaching plugs with creepage protection function in recent years, these attaching plugs are particularly suited for being arranged on the household electrical appliance such as air-conditioning, refrigerator and use.
Have the attaching plug of creepage protection function at present, although can play earth leakage protective function fairly perfectly, the defect still existed comprises:
First, light guide sheet must be positioned at directly over indicator light, and the light that indicator light sends could be received by sensitive film, and the relative position like this for indicator light and light guide sheet defines very large constraint.
Secondly, when the silver point folding on moving contact, can electric arc be produced, easily make indicator light sustain damage, shorten the use life of indicator light.
Again, the fixed form location of piezo-resistance is not very accurate, can have influence on production efficiency.
Finally, the live wire of the load power source line in wiring bin, zero line and ground wire can not be fixed exactly, thus produce inconvenience to follow-up welding operation.
Summary of the invention
For above-mentioned existing technological deficiency; the technical problem to be solved in the present invention is the attaching plug proposing a kind of improvement; while effectively realizing creepage protection function; can make indicator light can be relatively flexible relative to the position of light guide sheet; instead of must be positioned at immediately below light guide sheet, thus the layout of each parts can be optimized.
For this reason; the present invention proposes a kind of attaching plug with creepage protection function; it comprises housing and is arranged on the cartridge assemblies in described housing; described cartridge assemblies comprises the moving contact frame that is installed on and wiring board supports moving contact and the trip assembley therefor with moving contact co-operating; wherein; described cartridge assemblies also comprises indication component; described indication component comprises indicator light, light guide sheet and is obliquely installed in reflecting component between the two, and bending pins one angle of wherein said indicator light is also welded on described wiring board.By so arranging indication component, indicator light can be made not to be to be positioned at immediately below light guide sheet, thus indicator light can be relative flexible with the position of light guide sheet, and be conducive to the rational deployment of other parts.
According to a kind of execution mode; described indicator light is positioned in the indicator light protective cover on described moving contact frame; arc damage when indicator light can be made to avoid the silver point folding be subject at the duration of work of attaching plug on moving contact; the illumination that indicator light protective cover also can make indicator light send simultaneously is more intensively irradiated on reflecting component, effectively serves the effect of luminous instruction.
According to a kind of execution mode, described reflecting component is the reflective inclined-plane that described light guide sheet one end away from described indicator light is formed.Further, because reflective mirror is very common product, be easy to obtain, described reflective inclined-plane can adopt reflective mirror.It will be appreciated by those skilled in the art that described reflective inclined-plane also can utilize the reflex of other forms of optical equipment to realize the change of light path, such as, include but not limited to prism etc.Further, the angle on described reflective inclined-plane can be chosen for 45 degree.
According to a kind of execution mode, the pin of described indicator light can bend 90 degree.
According to a kind of execution mode, described cartridge assemblies also comprises piezo-resistance, and its pin is welded on described wiring board through after the location hole on described moving contact frame, piezo-resistance is located more exactly, enhances productivity.
According to a kind of execution mode, described housing comprises upper cover, bottom and bonnet, three wire blocking ports are provided with in wherein said upper cover, after the welding ends of the live wire of load power source line, zero line, ground wire is respectively put into welding hole, three heart yearns can be stuck in corresponding wire blocking port, effectively serve the effect that machinery is fixing, facilitate follow-up welding operation, enhance productivity.
By the improvement of above-mentioned each side; the attaching plug with creepage protection function provided by the invention can not only realize the function such as earth leakage protective, power line protection; still further provides the favourable layout to indicator light and protection; avoid the electric arc produced during the silver point folding on attaching plug duration of work moving contact to cause damage to indicator light, thus extend the use life of indicator light.In addition, the accurately fixing of the accurate location to piezo-resistance and the live wire to load power source line, zero line and ground wire can be realized, make the performance of attaching plug more reliable, use more safe and effective, ensure that the personal safety as well as the property safety of user.Meanwhile, Product Assembly is convenient, and product quality have also been obtained obvious raising.
