Description

The utility model relates to the field of electrical engineering and can be used to prevent a child from freely accessing the phase contacts of an electrical outlet. The device can find application both in residential premises and in kindergartens (kindergartens, nurseries, etc.).

Numerous designs of devices are known for preventing access to the contacts of an electrical outlet, including lockable locks [information can be found on the Internet at https://tech-svet.ru/cat/jung_cd_udaropr_svetlo-seriy_otkidnaya_krishka_s_zamkom_dlya_izdeliy_50h50] called plugs to protect children from electric shock. In particular, the Plug for the socket model 01IR.767556.015 is known [information can be found on the Internet at http://www.svetopribor.com.ua/s07/polystirol07.html], which is a three-dimensional figure of an elongated shape and equipped with pins designed for deepening into the contacts of an electrical outlet. The plug is easily installed in the socket, reliably closes the contacts, but does not have any devices for removing it from the socket. It is extremely difficult to extract such a plug from a deep socket of the Euro socket, not only for a child, but also for an adult.

The main direction of improving plugs is the use of various devices that facilitate the extraction of plugs for adults, but inaccessible to children.

The POMA plug is known [the information can be found on the Internet at https://www.wildberries.ru/catalog/2956317/detail.aspx], which looks like a disk with pins. In the disk along the axis perpendicular to the pins, two through holes are made. The plugs are removed from the socket outlets using plugs of electrical appliances, the plugs of which are inserted into the holes with force. The advantage of the design is its simplicity. The disadvantage is that during use, the holes are flared with plug plugs to such an extent that the plug becomes impossible to pick up with a plug and removed from the outlet.

Various designs of plugs with keys are known. Among them is the Baby Go plug [information can be found on the Internet at https://www.detmir.ru/product/index/id/541291/], made in the form of a convex disk with pins. The plug is removed from the outlet using the key included in the kit and inserted into a curly slot (keyhole) made in the body of the disk. The disadvantage of the design is the need to use a special key, which may be lost or broken.

There are various caps with protection against children with built-in devices for removing them from the outlet. Among them is a Daesung stub [the information can be found on the Internet at https://www.wildberries.ru/catalog/3133437/detail.aspx], which was adopted as a prototype. On the front surface of the stub there is a groove with a figured plate embedded in it along a pivotally mounted plate, on the edge of which there is a protrusion under the finger. In the closed position of the plug installed in the socket, the plate is recessed into the groove, the contacts are closed. To remove the plug, you need to pick up the edge of the plate with your finger, put it in a position perpendicular to the front surface, and pull on the plate. The main disadvantage of the design is its complexity, and therefore the high price. In addition, the miniature rotary mechanism with which the plate is fixed breaks off with time.

The utility model is based on the task of expanding the arsenal of tools and creating a reliable device that prevents a child from accessing the contacts of an electrical outlet.

The technical result achieved is a simplification of the design while making it possible to extract the plug from the socket of the socket with a publicly accessible curved wire product, in particular a paper clip, a hairpin, a hairpin, etc., available in every house.

The problem is solved in that the device for preventing unauthorized access to the contacts of the electrical outlet, made in the form of a plug, has pins designed to be inserted into the phase contacts of the electrical outlet. It differs from the prototype in that a recess is made on the surface of the plug opposite the font location, in which there is a pin with a hook at the end, while the surface of the hook facing the inward groove does not protrude beyond the edges of the recess.

The hooked pin may be in any shape suitable for these purposes. The main requirement is the inability to remove the plug from the outlet with your fingers, eliminating the possibility for the child to remove the plug by pulling the hook. Preferred is a design in which the pin with the hook is L-shaped with a tide at the end facing the indentation. Other designs are possible, for example, an arcuate bend (hook) of the pin inside the recess.

In the context of this application, the term "pin" is taken in the broadest sense, it can have a rounded or rectangular shape in cross section, can be made in the form of a plate having the same cross section as the hook.

It is also preferable to make pins buried in the contacts of the socket with longitudinal cuts, which allows the plug to be held equally well in different sockets (both in Euro sockets and in domestic ones designed for a smaller diameter of plug plugs).

The nature and scope of a true utility model can be understood based on the example below. It should be noted that the example is only illustrative and should not be construed as limiting the developed device.

An example implementation is illustrated by the Figures of the drawings, in which: FIG. 1 is a cross section of a plug; FIG. 2 is a plan view, FIG. 3 - removing the plug from the outlet using a paper clip.

The inventive device is made in the form of a plug made of a polymer material, the shape and dimensions of which allow it to be installed in the socket of an electrical outlet. To fix the plugs, it is equipped with two pins 1, intended for penetration into the phase contacts of the electrical outlet. A recess 2 is made on the surface of the body of the plug opposite to the location of the fonts 1, in which there is a pin 3 with a hook 4 at the end, together forming a L-shaped cross section. Moreover, the surface 5 of the hook facing the inward recess does not protrude beyond the edges 6 of the recess 2. At the end of the hook 4 there is a tide (roller) 7 facing the inside of the recess 2.

The pins have longitudinal cuts, which allows the plug to be installed and securely fixed in sockets of various designs due to the elastic convergence of the halves of the pins when inserted into the socket sockets. Such a plug cannot be removed by hand. No parts that could be caught by fingers protrude outward. The child cannot touch the contacts and cannot remove the plug from the outlet. At the same time, it is easily removed by adults - it is enough to hook, for example, a paper clip, a hairpin, etc., and pull it towards you. The roller prevents the paper clip from slipping off the hook. The simplicity of design and the absence of the need to use a special key is an advantage of this device.
