Abstract

A double cross control waterproof socket capable of effectively avoiding misplug mainly comprises a socket body, a socket cover, rotating covers, a torsional spring, a small rotating shaft, convex bosses, a spring, contact strips, transition connecting strips and external terminal strips. When a plug is inserted in the socket, the rotating cover 5 is turned so that the contact strip 11 contacts with the transition connecting strip 7; the rotating cover 14 is turned so that the contact strip 10 contacts with the transition connecting strip 12; and then the convex boss 6 is pressed downwards so that the transition connecting strip 7 contacts with the external terminal strip, and the convex boss 15 is pressed downwards so that the transition connecting strip 12 contacts with the external terminal strip 13, thus, the plug is energized completely. Electric shock cannot be caused in a single object misplug hole under the condition of not simultaneously pressing down the convex boss at one side and not turning the rotating cover.

Description

Double cross control waterproof socket

Technical field

The utility model relates to a kind of double cross control safety of single phase poaer supply socket and the device of waterproof, the safety socket that can effectively avoid children to misplug.

Background technology

Common in the market popular safety socket is to have increased by one level and smooth skewback device to cover jack in socket aperture basically.But this device still has many shortcomings, at first is to use inconvenience, because parallel sliding often has stuck phenomenon, secondly; still have potential safety hazard,, may have an accident, once more if there is conductor to misplug in the hole; can not waterproof, if there is water to sprinkle, may cause short circuit.

The utility model content

At above shortcoming, the socket that the utility model provides, not only coefficient of safety improves, and easy to use, waterproof.

The technical scheme that its technical problem that solves the utility model adopts is: design according to the double cross control principle, at bilateral contact chip, transition brace, external wiring piece and the projection installed respectively of pedestal, the outer jack periphery has sealing ring to cling in the flap, the flap jack is by little rotating shaft, and the hub cap of torsion spring assembling activity covers.The projection that protrudes flap is withstood on the sealing ring by spring, plays waterproof action.The grounding wafer cavity of pedestal and positive and negative two utmost point cavitys separate, and pedestal and flap are tightened with self-tapping screw.

When object inserts wherein on one side jack, stir hub cap, depress the contact chip that extends through from another side seat hole by hub cap and contact, simultaneously, the projection in other hole, hole is depressed with the transition brace, transition plate is contacted with external wiring piece, at this moment, just the other side of conduction is the interior contact chip of jack on one side, and a side who inserts, owing to do not rotate the other side's hub cap and depress projection, still do not have.Because the action that plug inserts is bilaterally to carry out simultaneously, and is inserted into the end, so can conduct electricity.In the ordinary course of things, children can not insert two objects to two holes simultaneously, and, depress two projections simultaneously, so coefficient of safety improves obviously.

The beneficial effects of the utility model are: can avoid children to misplug and cause electric shock accidents, and waterproof, use flexibly.

Embodiment

Below in conjunction with description of drawings enforcement of the present utility model is described in further detail.

In Fig. 1, Fig. 2, be assemblied in of the effect of the interior hub cap 5,14 of flap 1 positive and negative second hole by torsion spring 4,17, cover jack and be close to sealing ring 18, projection 6,15 also is close to sealing ring because of spring 9 and is protruded the flap surface,

contact chip

10,11

transition braces

7,12 elasticity by self are former beginning and end conducting state, and pedestal 2 is tightened with flap 1 usefulness self tapping sieve silk 20.

Fig. 3, embodiment illustrated in fig. 4 in, when inserting the seat holes, stir the hub cap 5,14 bilateral hole in plug 19, by the effect of hub cap, depress the contact chip 10 that the other side's extension comes respectively and contact with transition brace 12, contact chip 11 contacts with transition brace 7; Then, in deep process, two projections 6,15 are depressed in the baseplane of plug, and be close to flap face seal circle 18, under the effect of projection, force transition brace 7 to contact with external wiring piece 8, transition brace 12 contacts conducting with external wiring piece 13, so far, the whole conductings of plug 19 positive and negative secondarys.

Claims

1, a kind of waterproof socket of double cross control, movable hub cap 5,14 is installed in flap, the bilateral installation contact chip 10,11 of pedestal, transition brace 7,12, external wiring piece 8,13, and the projection 6,15 that protrudes the flap surface are on one side respectively extend to the other side at contact chip one position, it is characterized in that: the hub cap on the flap 1 respectively is the contacting of control the other side contact chip and transition brace, and projection is respectively for controlling contacting of the other side's transition brace and external connection.

2, double cross control waterproof socket according to claim 1, it is characterized in that: the neighboring is stained with sealing ring 18 in the flap jack, and movable hub cap also covers jack with little rotating shaft 3,16, torsion spring 4,17 assemblings.

3, double cross control waterproof socket according to claim 1 is characterized in that: the bilateral projection of respectively installing in the pedestal, and owing to spring protrudes the flap surface.

4, double cross control waterproof socket according to claim 1 is characterized in that: contact chip 10, the 11 one positions of bilateral installation extend to the other side's another side in the pedestal.

5, double cross control waterproof socket according to claim 1 is characterized in that: bilateral installation is used to connect the transition brace of conducting contact chip and external wiring piece in the pedestal.
