Abstract

The utility model relates to an anti-falling plug comprising a plug board and a conductor wire. Symmetrical metal plugging sheets are arranged at the upper end of the plug board; one ends of the metal plugging sheets are exposed out of the plug board and the other ends of the metal plugging sheets are fixed in the plug board and is connected with the conductor wire. Clamp grooves are arranged at the inner sides of the metal plugging sheets; anti-falling hooks are arranged inside the clamp grooves; and the anti-falling hooks and the metal plugging sheets are movably connected by an elastic button. The hooking portions of the anti-falling hooks are exposed out of the clamp grooves; and when the elastic button is pressed, the hooking portions of the anti-falling hooks enter the clamp grooves. The elastic button includes button keys and springs; the button keys are symmetrically distributed at the side portions of the plug board; the springs are arranged between the button keys and are also arranged in the plug board; and inner-side protruding columns of the button keys successively pass through the metal plugging sheets and the anti-falling hooks and then are abutted against the springs. The provided anti-falling plug has the advantages of uneasy falling, good security and stability, simple and reasonable structure, convenient usage, good security and reliability, and long service life.

Description

A kind of slip-off preventing plug

Technical field

The utility model relates to a kind of plug, especially relates to a kind of slip-off preventing plug.

Background technology

Plug refers to that a kind of and socket form the connector of plug connector, and it generally matches with socket, refer to unfixed half.According to its structure difference, generally be divided into two and insert or three insert, its any plug causes the insecurity of its use easily.The Chinese patent name is called a kind of new type of plug (application number CN201120455297.2) and discloses a kind of at existing like product poor stability, and the anti-plug that plugs the not good enough technical problem of structural design and design, its main points are that the plate outer end of copper plug is provided with through hole, and through hole is arranged at place, copper plug hole; Be provided with symmetrically arranged button spindle in the plate, be provided with spring between the button spindle, the both sides that the press-side of button spindle one end exposes plate respectively, the other end stretches out the copper plug hole of plate respectively, the inserting-plate hole place of this end is provided with the card post respectively, the card post passes and exposes the through hole of copper plug respectively, the card post of button bar tilts to plate, the through hole of the oblique insertion copper plug of card post, thus prevent plug by plug arbitrarily, but this plug can't have the outside double plug-and-socket of semicircle shape to fix, thereby can not play the effect of slip-off preventing, simultaneously this new type of plug in use, the card post need prepare the location enter in the through hole, cause misoperation easily, and the card column diameter is thinner, after long-time the use, fracture easily, the useful life of having reduced this plug.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of misoperation of avoiding, fail safe, good stability, and the slip-off preventing plug of long service life.

The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of slip-off preventing plug, comprise plate and conductor wire, described plate upper end is provided with the metal insert of symmetry, one end of described metal insert is exposed to described plate, the other end of described metal insert is fixed in the described plate and with described conductor wire and is connected, the inboard of described metal insert is provided with draw-in groove, be provided with dropping-proof hook in the described draw-in groove, described dropping-proof hook and described metal insert flexibly connect by elastic button, the hook portion of described dropping-proof hook is exposed to outside the described draw-in groove, press described elastic button, the hook portion of described dropping-proof hook enters in the described draw-in groove.

Described elastic button comprises button key and spring, described button key is symmetrically distributed in the both sides of described plate, described spring is between described button key and be positioned at described plate, and the inboard projection of described button key passes described metal insert and described dropping-proof hook and described spring successively and connects.

Described plate inboard is provided with spring groove, and described spring is symmetricly set in the both sides of described spring groove, and offsets with the inboard projection of described button key respectively.

Be provided with the button activity guide vane end stop between the inboard of described button key and the described metal insert.The space of the activity by the movable guide vane end stop control of button dropping-proof hook, like this can be accurately dropping-proof hook control in the space that limits, thereby embody the accuracy of design.

Compared with prior art, advantage of the present utility model is: a kind of slip-off preventing plug of the utility model, comprise plate and wiring, the plate upper end is provided with the metal insert of symmetry, one end of metal insert is exposed to plate, the other end of metal insert is fixed in the plate and with described conductor wire and is connected, the inboard of metal insert is provided with draw-in groove, be provided with dropping-proof hook in the draw-in groove, dropping-proof hook and metal insert flexibly connect by elastic button, with this slip-off preventing plug insertion socket, utilize the hook portion of dropping-proof hook to hook socket, difficult drop-off, fail safe, good stability is pressed elastic button, the hook portion of dropping-proof hook enters in the draw-in groove of metal insert, just can easily take off attaching plug, this slip-off preventing plug uses lever principle to drive hook and makes it do compound motion, have simple and reasonable, easy to use, safe and reliable, avoid misoperation, the advantage of long service life.
