Abstract

The utility model provides a safety socket capable of preventing short circuit caused by entered water. The socket is connected with a power source plug; the socket comprises a circular arc-shaped rubber panel; the panel is provided with elastic jack protruding structures; jacks are arranged on the jack protruding structures; the width of each jack is smaller than that of a pin of a standard plug; and the length of each jack is slightly smaller than that of the pin of the standard plug. When the safety socket is used, the jack protruding structures can prevent water from lingering on the panel; the circular arc-shaped rubber panel can also prevent the water from lingering on the panel; the jack protruding structures can be adopted as water-prevention stages and enables water which has been splashed on the panel to be drained fast; and when the plug is inserted in the socket, the contact of the plug and the protruding structures can be maintained, and therefore, each pin can be sealed; and with the jacks which are slightly smaller than the plug adopted, liquid can be prevented from permeating the socket in a standby state by means of internal/external pressure difference and the tension of the liquid itself.

Description

Safety socket

Technical field

The utility model relates to socket.

Background technology

Socket is a kind of common daily living article.In daily use, the jack of socket is bigger, as runs into the liquid spilling, infiltrates easily, can produce as unsafe factors such as electric leakage, short circuits.Waterproof socket on the market is much now, as State Intellectual Property Office's novel practical patent that May 14, the disclosed patent No. was ZL 200720121286.4 in 2008, namely disclose a kind of socket with water-proof function, it is mainly by adding the function that the cover plate that has sealing rubber ring is realized absolute waterproof at socket.But the disclosed socket of this utility model patent also has certain defective: at first, add the cover plate that has sealing ring to socket socket is complicated, production cost increases; Secondly, the cover plate that has sealing ring can only be realized that is to say the function of waterproof when covering, and is opening cover plate, and when plugging in, cover plate can not be waterproof action.

Summary of the invention

The purpose of this utility model provides a kind of into safety socket of water short circuit that prevents, for this reason, the utility model by the following technical solutions:

The utility model comprises socket, described socket links to each other with attaching plug, described socket comprises the rubber panel of circular arc, described panel is provided with flexible jack bulge-structure, described jack is arranged on the jack bulge-structure, the width of each jack is less than the width of the pin of standard plug, and length is slightly less than the length of the pin of standard plug.

By above technical scheme, when the utility model used, the jack bulge-structure can be prevented the superincumbent stop of sealing.The arc rubber panel also is that the jack bulge-structure both can be used as the waterproof platform for the anti-stop of sealing on panel, can allow water drain fast after being got on by spilling again.Can when plug is plugged, keep the contact between plug and the raised structures again, thereby reach each stitch be sealed; The socket more smaller than plug, can prevent that under stand-by state liquid from infiltrating socket by self tension force of inner and outer air pressure difference and liquid, and under the use state, soft rubber panel can not cause excessive difficulty to the insertion of stitch, and can after inserting, plug reach the isolated effect of external seal in the socket.

Embodiment

Ask for an interview shown in the accompanying drawing, the utility model comprises raised structures 3, the integrated switch 4 on jack bulge-structure 1, arc rubber panel 2, the plug.

The utility model comprises socket, described socket links to each other with attaching plug, described socket comprises the rubber panel 1 of circular arc, described panel is provided with flexible jack bulge-structure 1, described jack is arranged on the jack bulge-structure 1, the width of each jack is less than the width of the pin of standard plug, and length is slightly less than the length of the pin of standard plug.

When the utility model used, jack bulge-structure 1 can be prevented the superincumbent stop of sealing.The arc rubber panel also is that jack bulge-structure 1 both can be used as the waterproof platform for the anti-stop of sealing on panel, can allow water drain fast after being got on by spilling again.Can when plug is plugged, keep the contact between plug and the raised structures again, thereby reach each stitch be sealed; The socket more smaller than plug, can prevent that under stand-by state liquid from infiltrating socket by self tension force of inner and outer air pressure difference and liquid, and under the use state, soft rubber panel can not cause excessive difficulty to the insertion of stitch, and can after inserting, plug reach the isolated effect of external seal in the socket.

Raised structures is also arranged on the attaching plug of socket, be used for guaranteeing the applying waterproof between attaching plug and the supply hub.There is not the space between integral switch and the socket panel, one-body molded.

The jack details as shown in Figure 2, the jack edge has the slope, is used for guiding the stitch of plug to strut jack.

The section of the projection of jack as shown in Figure 3.Such structure can also utilize the tension force of water and inner and outer air pressure difference to prevent that water droplet from infiltrating socket.Arc rubber panel following also has inner plastic front board, is used for keeping the shape of rubber panel.

Plug inserts state as shown in Figure 4, and when plug inserted, the plug stitch was big with the jack support, and the plane of plug and the raised structures on the socket panel are fitted, and reach the purpose of sealing and waterproof.

Above-mentioned embodiment is used for the utility model of explaining; rather than the utility model limited; in the protection range of spirit of the present utility model and claim, any modification and change to the utility model is made all fall into protection range of the present utility model.

Claims

1. safety socket, it is characterized in that, described socket links to each other with attaching plug, described socket comprises the rubber panel of circular arc, described panel is provided with flexible jack bulge-structure, described jack is arranged on the jack bulge-structure, and the width of each jack is less than the width of the pin of standard plug, and length is less than the length of the pin of standard plug.
