Safety socket

A socket, particularly a safety socket that maintains an open state when the plug is not fully inserted.

Most of the traditional power outlets used in homes are often placed in a less conspicuous place or in a lower position for the visual aesthetics of the interior design. For example, most household power outlets are mostly placed on the wall from the ground to the height of 30 cm, so they are in a position that is easily touched by young members of the family. The most common case is that young members of the family are driven by curiosity to insert foreign objects into the socket of the power socket. If the foreign object is made of a conductive material, it may cause an accident of electric shock to the young member.

A common protective measure is to insert a plastic protective cover with a similar plug structure into the power socket. However, this will cause the user to remove the plastic protective cover every time the user uses the power socket, and must be re-used after use. It is not convenient for the user to insert the plastic protective cover. And the plastic protective cover can be easily removed by hand. Once the plastic protective cover is removed, the socket of the power socket will still be exposed, and young members may still be in danger of electric shock.

Another common protective measure is to close the entire power socket with a plastic cover. However, this will also cause the user to open the plastic protective cover every time the user uses the power socket. The plastic protective cover is not convenient for the user. Young members may still cover the plastic cover themselves. Once the plastic cover is opened, young members may still be at risk of electric shock.

In addition, when the plug of the electrical appliance is not fully inserted into the power socket, especially the high-power electrical appliance, it is easy to cause the plug part to heat and melt during use, and even cause serious injury or property damage.

In view of this, the present invention proposes a safety socket, which is not provided when only a single jack has an inserted item, or when the plug of the electrical appliance is not fully inserted into the jack, thereby solving the above problem. Personnel are prone to electric shock and problems such as heat and melting of the plug part that may result when the plug is not fully inserted into the power outlet.

A part of the second inner connecting portion 172a of the second elastic conductor 172 is located between the movable member 15 and the second metal electrode 132. When the movable member 15 is at the second position as shown in FIG. 5, the second elastic conductor 172 A part of the second inscribed portion 172a is pushed against the second metal electrode 132 by the enlarged portion 151.

In one embodiment of the present embodiment, the enlarged portion 151 includes an annular flat surface 151a, and the enlarged portion 151 is pushed against the first elastic conductor 171 and the second elastic conductor 172 by the annular flat surface 151a.

The first elastic conductor 171 of the present embodiment includes a first inner connecting portion 171a and a first outer connecting portion 171b. The first inner connecting portion 171a is erected on the inner surface 112d of the lower casing 112 and is located at the enlarged portion 151 and the first metal. Between the electrodes 131. When the movable member 15 is at the second position as shown in FIG. 5, the first inscribed portion 171a is pushed by the enlarged portion 151 to come into contact with the first metal electrode 131.

The second elastic conductor 172 of the embodiment includes a second inner connecting portion 172a and a second outer connecting portion 172b. The second inner connecting portion 172a is erected on the inner surface 112d of the lower casing 112 and is located at the enlarged portion 151 and the second metal. Between the electrodes 132, when the movable member 15 is at the second position as shown in FIG. 5, the second inner connecting portion 172a is pushed by the enlarged portion 151 to come into contact with the second metal electrode 132.

In one embodiment of the present embodiment, the first outer connecting portion 171b of the first elastic conductor 171 abuts against the outer surface 112e of the lower casing 112, and the second outer connecting portion 172b of the second elastic conductor 172 abuts the lower portion. The outer surface 112e of the housing 112.

The movable member 15 of the embodiment further includes a stopping portion 152. The size of the stopping portion 152 is larger than the through hole 111c of the upper casing 111. When the movable member 15 is at the first position as shown in FIG. 4, the stopping portion The 152 abuts against the inner surface 111d of the upper casing 111.

One of the functions that can be achieved by the safety socket 1 described in the above embodiment is that when only one single jack has an inserted item, or the plug 21 of the electric appliance 2 is not fully inserted into the jack of the safety socket 1, the present creation Safety socket 1 does not provide power. Further, as long as the end surface 15a of one end of the movable member 15 is not pushed by the plug 21 to be flush with the top surface 111e of the upper casing 111, the enlarged portion 151 is not pushed into the first inner portion of the first elastic conductor 171. The connecting portion 171a and the second inner connecting portion 172a of the second elastic conductor 172 are brought into contact with the first metal electrode 131 and the second metal electrode 132, respectively. At this time, even if a child inserts a foreign object into the jack of the safety socket 1 of the present embodiment, there is no risk of electric shock. Or when the plug 21 of the electric appliance 2 is not fully inserted into the safety socket 1, the same electrical appliance 2 cannot obtain electric power operation, and there is no need to worry about the plug 21 being overheated and melted.

Another effect that can be achieved by the safety socket described in the above embodiments is that since the color of the insulation skin of the mains power supply and the ground wire is not uniform, the skin color of the wire cannot be 100% confirmed to be powered. The fire line, which is the ground wire that is not powered. That is to say, once the power outlet is installed, even the originally installed electrician can not clearly determine which jack is connected to the power line by the naked eye without measuring the meter. Behind the jack is a ground wire that is not powered. The paradox is a general user. The embodiment of the present invention is that the two jacks are in an open state, so no matter how the socket is installed at the beginning, there is no fear that the electrically conductive foreign object may be accidentally inserted into the jack to be electrically shocked.

Although the technical content of the present invention is described above with respect to an embodiment having two jacks, for those of ordinary skill in the art, the teachings according to the above embodiments can be easily transferred to a three-hole socket. Because the third hole of the three-hole socket is only a grounding wire for guiding the leakage current of the electrical appliance to the earth, it is not the ground wire and the fire wire constituting the entire electrical circuit. Moreover, those of ordinary skill in the art can readily transfer to the sockets of the extension cords in accordance with the teachings of the above-described embodiments.

In conclusion, the present invention has been disclosed in the above preferred embodiments, but it is not intended to limit the present invention. Anyone who is familiar with the art, and some modifications and retouchings that do not depart from the spirit of the present invention should be included in the present disclosure. Within the scope of creation, the scope of protection of this creation is subject to the definition of the scope of the patent application attached.
