Description
Technical field
The utility model relates to plug technical field, particularly relates to a kind of plug with telescopic earth polar latch.
Background technology
The plug that existing converter jack is joined, is divided into two types: the first is the two poles of the earth plug latch not with ground, because of no ground protection, can not carry out available protecting to the electrical equipment of user, can bring certain potential safety hazard to the electrical equipment of user; The second is the two poles of the earth plug with ground, the earth polar latch of partial plug is virtual earth, though have ground pin but it can not be energized, portioned product earth polar latch is fixed, the two poles of the earth plug without earth polar latch can not be converted to, so just cannot mate with some converter jack without the need to earth polar latch, versatility is poor.
Utility model content
The utility model, in order to solve the aforementioned problems in the prior, provide between a kind of the two poles of the earth, three poles and can mutually change, the plug of the band telescopic earth polar latch of easy to operate, spacing stable, highly versatile.
To achieve these goals, the utility model adopts following technical scheme:
A kind of plug with telescopic earth polar latch, comprise Plug base, the two poles of the earth latch, described Plug base comprises substrate, the bayonet mount that bottom is communicated with substrate, described the two poles of the earth latch is arranged in bayonet mount, position in plug mount pad between the latch of the two poles of the earth is provided with earth polar latch fairlead, earth polar latch is provided with in described earth polar latch fairlead, the corresponding position of bayonet mount top and earth polar latch fairlead be provided with for earth polar latch flexible dodge hole, the bottom of described bayonet mount is also provided with supporting seat, bottom the latch of described earth polar and be provided with stage clip between supporting seat, be provided with for stretching out earth polar latch in described Plug base, the latch position-limit mechanism that retraction two extreme positions are spacing.When also spacing by latch position-limit mechanism in earth polar latch retraction fairlead, plug is now the no ground plugs in the two poles of the earth, when needs ground connection, throw off latch position-limit mechanism, earth polar latch stretches out outside Plug base from dodging hole under the effect of stage clip, and then spacing by latch position-limit mechanism, now become the two poles of the earth grounded plug, i.e. three-terminal polarized plus plug, thus can realize changing between the two poles of the earth, three poles, easy to operate, spacing stable, highly versatile.
As preferably, described latch position-limit mechanism comprise at base plate bottom and for the spacing movable banking stop of earth polar latch, be located in bayonet mount and fixing catch between active blade and earth polar latch fairlead, described earth polar latch fairlead is provided with in its side near fixing catch and dodges gap slot, the bottom of described earth polar latch is provided with guide vane end stop, when movable banking stop is adjusted to spacing state, the two ends up and down of movable banking stop respectively and fixing catch, formed between supporting seat and be used for the spacing upper limit portion of guide vane end stop, lower limit portion.When earth polar latch be in retraction, stretch out two extreme positions time, the guide vane end stop on the latch of earth polar is spacing respectively by lower limit portion, upper limit portion, thus to prevent in use procedure earth polar latch to loosen, departs from, uses safer, stablize.
As preferably, be rotationally connected between described movable banking stop and substrate.Movable banking stop inwardly rotates guide vane end stop spacing, cannot stretch after earth polar latch is spacing; When movable banking stop outwards rotates, guide vane end stop is cancelled spacing, and earth polar latch can stretch along earth polar latch fairlead.
As preferably, be slidably connected between described movable banking stop and substrate.Movable banking stop inwardly slides spacing to guide vane end stop, cannot stretch after earth polar latch is spacing; When movable banking stop outwards slides, guide vane end stop is cancelled spacing, and earth polar latch can stretch along earth polar latch fairlead.
As preferably, described the two poles of the earth latch, the top end face of earth polar latch are sphere.Sphere is convenient to be connected with jack.
As preferably, be provided with stage clip spacing hole vertically bottom the latch of described earth polar, the upper end of described stage clip is stretched in stage clip spacing hole.Stage clip upper end is stretched in the latch of earth polar, thus prevents stage clip pressurized and bend and throw off with earth polar latch, thus ensures that earth polar latch is flexible more stable.
As preferably, between described supporting seat, ground strip with plug substrate, bolt is connected.Bolt connects, assembling, convenient disassembly, changes parts convenient.
As preferably, be also provided with ground strip in described earth polar latch fairlead, described ground strip comprises elastic conducting strip, brace, and described elastic conducting strip contacts with earth polar latch side elastic, and described brace is connected with substrate.Earth polar latch is by ground strip ground connection.
Therefore, the utility model has between the two poles of the earth, three poles can be changed mutually, the beneficial effect of easy to operate, spacing stable, highly versatile.
