Abstract
The utility model relates to a changeable two or three pins power supply plug. The utility model is characterized in that the earthing pin is provided with a through hole which is movably connected with a supporting axle. The middle part of a base is provided with a recess, and the earthing pin can be inserted into the base. The base is also provided with a through hole where the fire wire and the central line pins are desired to be rotated. The fire wire and the center line pins are provided with a rotating connecting block which can be rotated linking with the pins. The utility model has the advantages of strong applicability and flexibility. With simple transformation, the utility model can be used as a double connecting and inserting device as well as a three connecting and inserting device, thus the trouble of disassembling and assembling is avoided, on the other hand, the pins can not be twisted forcibly, increasing safety factor.
Description
The utility model relates to a kind of attaching plug, is specially adapted to the attaching plug of three pins that two pin plug that are made of live wire and center line pin or earth connection pin, live wire and center line pin constituted.
In the prior art, the pin of attaching plug is fixed form, and Two-feet plug and three plugs can not exchange, and promptly three-pin plug can not patch two hole socket, and simultaneously, Two-feet plug can not be used for three hole flat sockets.As fixing three-pin plug is changed system into Two-feet plug, the ground connection plug-in pin must be removed.As also need the pin of live wire and center line is forced torsional deflection when patching flat two receptacle electrical connectors.So both increased its unsafe factor, use is very inconvenient again.
The utility model purpose is to overcome above-mentioned shortcoming, and a kind of disposable two, three pin attaching plugs are provided.
The utility model is achieved through the following technical solutions its purpose, the attaching plug that is constituted by base, grounding pin, live wire and center line pin, cartridge fuse, indicator light, lid, grounding pin is the L shape, the end has breach, and on grounding pin, be equipped with a through hole, this through hole connects with bolster is movable, and bolster is fixed on the base by fixed block, and is equipped with back-moving spring.Base middle part is provided with a groove that grounding pin can be placed in it, and is equipped with one and can makes grounding pin be fixed on slide block in the base groove, also is equipped with a ground connection plate within it.Simultaneously, also be provided with on the base and can make live wire and the required through hole of center line pin rotation, be equipped with the rotation coupling block that the linkage pin rotates together on live wire and the center line pin.Live wire and center line pin connect with base and interior benevolence activity by rotating coupling block, and are equipped with the corner location on the rotation coupling block.
The utility model compared with prior art has following advantage; Applicability and flexibility are strong, and the utility model can be directly used in two and patch equipment by simple conversion, also can be directly used in three and patch equipment.Avoid the trouble of dismounting like this, do not forced again to reverse pin, increased safety factor.
Below in conjunction with drawings and Examples the utility model is elaborated:
Fig. 1 is that the utility model is removed the loam cake front view;
Fig. 2 is the utility model longitudinal sectional drawing:
Fig. 3 is that the utility model bottom surface is to view;
Fig. 4 is the utility model live wire and center line plug-in pin profile:
Fig. 5 is the utility model current limliting and power supply input discrimination principles figure:
With reference to accompanying drawing, the utility model helps pad 11, slide block 12, back-moving spring 13, location 14, rotation coupling block 15, fixed block 16, cartridge fuse 17, indicator light 18 to constitute by grounding pin 1, live wire pin 2, center line pin 3, base 4, lid 5, transparent removable cover 5, bolster 7, back-moving spring 8, interior benevolence 9, ground connection plate 10, plate.
Grounding pin 1 of the present utility model is shaped as the L type, the end has breach, can be around bolster 7 axis swings, bolster 7 is fixed on the base 4 by fixed block 15, and the back-moving spring 8 of grounding pin 1 is housed, can grounding pin 1 be fixed in base 4 grooves by slide block 12, and simultaneously L type presser feet opens circuit with ground connection plate 10, pin 1 resets under back-moving spring 8 acts on and contacts conducting with ground connection plate 10 when slide block 12 discharges.Live wire and center line pin 2,3 gaps connect rotation coupling block 15, offers pin 2,3 on base 4 and the interior benevolence 9 and rotate required through hole, and rotation coupling block 15 rotates the blind hole that is cooperated.Pin 2,3 linkages rotate coupling block 15 and rotate with respect to base 4 and interior benevolence 9 blind holes, on interior benevolence 9 and the rotation coupling block 15 location are set, and accurately put in place to guarantee that pin 2,3 rotates.Thereby reach the convertible purpose of two, three pins.
Former primary state is three pins, when need during with two pins, with grounding pin 1 in the bolster 7 that is fixed in fixed block 16 is rocked to base 4 grooves, simultaneously with slide block 12 to reverse mobile compression reseting spring 13, release slider 12 is inserted in the ground connection plug-in pin breach under back-moving spring 13 effects.Thereby grounding pin 1 is fixed in the groove.Then, with live wire pin 2 clockwise 14 positions, location to interior benevolence 9.Center line pin 3 is reversed 14 positions, fastening position.
Former primary state is two pins, when need during with three pins, will move behind the slide block 12 and discharge grounding pin 1, and grounding pin 1 resets under the effect of back-moving spring 8, and plate 10 of pressure holding ground connection and plate help pad 11, the contact conducting.Then live wire pin 2 is reversed 14 positions, fastening position, with 14 positions, the clockwise fastening of center line pin position.
With reference to Fig. 5, for safety and reliability in use, the utility model has also increased current-limiting apparatus and indicator light.When energized, indicator light 18 gets electroluminescence, cartridge fuse 17 overload cut outs during as the electric overcurrent of equipment, because cartridge fuse 17 its rated current perseverances of selecting for use are less than the main fuse rated current, so do not influence normal power supply to miscellaneous equipment, then transparent removable cover 6 is moved backward and open transposing cartridge fuse 17.
