Description

ANTI-SHOCK OUTLET

APPLICATION FIELD

[001] This application for a patent for invention deals with an anti-shock socket, particularly a socket designed to be used with zero risk of shocks, which is particularly useful for children, and its field of application is aimed at electricity area.

BRIEF INTRODUCTION

[002] The socket that motivates this patent application comprises a device of mechanical construction equipped with a fixed part arranged inside the socket, and the electrical contact is in the upper part of the said device which, when pulled, causes them to be made the electrical contacts releasing the electric current; when the movable part is pushed into the socket, there is a complete cut with the electrical connector, completely excluding the risk of electric shock; this set includes protective latches that make it difficult to remove the device easily. Optionally, the movable part can be locked when pushed and, with a quick click in the same pushing direction, unlocked and released mechanically.

STATE OF THE TECHNIQUE

[003] It is known to all those affected in the area that, particularly, children from 1 (one) to 7 (seven) years are the biggest victims of accidental electric shocks in sockets or similar. In addition to fingers, children can make use of conductive materials such as nails, staples or other metallic materials.

[004] Some means are used in the state of the art in order to avoid the occurrence of electric shocks in socket areas, notably for the protection of children or other users, being certain that inadvertently placing fingers in socket holes can generate electrical discharges unwanted actions, the consequences of which can be serious.

[005] In this sense, plastic devices fitted into the socket holes are known, in order to prevent the insertion of body parts in these areas. However, these means, in addition to being able to be removed with certain ease, also have the inconvenience of requiring complete removal when the use of the socket is desired, which can lead to forgetting when replacing it; being certain that this placement and removal movement is not always executed with due necessity. [006] It is known from the prior art document US2002104745, published on 08/08/2002, which describes a shock-resistant electrical outlet designed to prevent the application of energy to the outlet only when a standard electrical plug is inserted almost entirely into the Jack. This is accomplished by providing at least two normally open switches in series circuit between the line voltage contact and an internal voltage contact which is actuated by the voltage pin of an electrical plug inserted into the outlet. The switches are closed by switch actuators located for simultaneous engagement by the neutral and voltage pins of an electrical plug when it is almost fully inserted into the outlet to complete a circuit between the line voltage contact and the internal voltage contact in the switch slot. outlet voltage. [007] This previous document, although efficiently shown, has a complex construction, including many components and not having the simplicity of construction and use observed in the present invention, where only through a linear movement, it is possible to take the device from a condition of impediment to a condition of use. [008] Document US5944542, published on 08/31/1999, shows an electric shock safety plug, which follows conventional safety standards, that is, it must be placed and removed from a socket in order to prevent the passage electrical current or release it.

INVENTION

[009] The present invention comprises a system with intelligent mechanical control, through which it is possible to block 100% in the cut of electrical energy, reassuring users about the possibility of shock by introducing conductive material such as hairpin, wires bare metal, nails, pins and any pointed conductive material, normally used by children inside a residence, thus avoiding any kind of threat of electric shocks and, consequently, bringing total safety to users and/or consumers.

[010] Technically, the new invention comprises a totally different modality, with a different purpose in relation to the state of the art, given that the currently known products offer power outlets with energy present in their terminals, constantly; on the contrary, the object of the present invention does not contain energy, under normal conditions of rest, which leads to the safety of use advocated and inherent to the object of the invention, for which the present patent is claimed. ADVANTAGES OF THE INVENTION

[011] In addition to those evident from the preceding description, the following advantages can be highlighted:

- Simple and practical device;

- Device that completely eliminates the possibility of any accidental electric shock, without the need to remove the device from the socket;

- Device that locks the plug of the equipment to be connected to the electrical network;

- Device that, after removing the plug from the equipment, makes it possible for the socket to be exempt from the passage of electric current;

- The device is installed to the socket, and its use condition only changes from a linear movement between the mobile part and the fixed part of the device.

GENERAL DESCRIPTION OF THE INVENTION

[012] The present invention stands out for being essentially composed of two parts, one that is installed in the socket of the electrical installation in a fixed way and another that is applied, by sliding fit, to the said first part; in this second part, or mobile part, the elements of metallic contact to the electrical connectors are arranged, and a locking device is also foreseen, through which, once the plug of the equipment to be connected to the power network is inserted, it is moved to a position electric current transmission position, and in this position, the plug of the equipment remains locked, preventing its removal. When the plug of the equipment to be powered is introduced into the moving part, the lock that retains the aforementioned plug is activated, in addition to providing the passage of energy; at this time, the moving part can be moved outwards and the plug can no longer be pulled out, until the moving part is moved inwards, when the latch is released and the plug can be pulled out freely, simultaneously with this, no there is a passage of electrical energy. This position will be used as a way to avoid electric shocks, even when inserting conductive materials in the holes.

DETAILED DESCRIPTION OF THE INVENTION

[014] The shockproof socket, object of this patent application, comprises a device composed of a fixed part (1) and a mobile part (2), the aforementioned fixed part (1) being coupled to a conventional socket (T) , said movable part (2) being provided with metal rods (3) that pass through the fixed part (1); said movable part (2) provided with holes (4) for receiving a conventional plug (P) of equipment to be connected to the power grid.

[015] The set projects metal power connection rods (5) that connect the mobile part (2) to the fixed part (1), existing between the same helical springs (6); the aforementioned metal power connection rods (5) have "L" configurations at the ends (7), acting, when in power passage mode, to the metal contactors (8) provided for in the fixed part (1) and interconnected to the power supply.

[016] Inside the movable part (2) are inserted plates (9), bearing in transverse axes (10), while, centrally, a lock assembly (11) is arranged, where an arm (12) is articulated on a support (13), supported by a pin (14); said arm (12) having a tip (15) arranged next to a spring (16) and a flap (16') at the other end, so that, when activated by the interaction between the mobile part (2) and the fixed part ( 1 ), as well as by applying the conventional plug (P) to the mobile part (2), promotes the locking of said plug (P) preventing its removal. That is, when the plug (P) is inserted into the mobile part (2), the lock set (11) is released so that the mobile part can be moved towards the outside of the environment, promoting the connection for the passage of energy. At this moment, the withdrawal of the plug (P) is prevented by the action of the locking set (11); the release of the latter will only occur when the mobile part (2) is moved inwards, a movement that, similarly, prevents the passage of electrical energy. [017] At the moment when the outward movement occurs, the metal power connection rods (5) whose ends (7) are located away from the metal contactors (8), are moved until they find and plug into the aforementioned metal contactors (8 ), so that the passage of energy is promoted; Simultaneously, the lock assembly (11), through the flap (16'), prevents the removal of the plug (P), which is temporarily retained by said flap (16').

[018] Therefore, once the plug (P) is removed from the inside of the device, which requires linear displacement of the moving part (2) towards the inside until the metal power connection rods (5) are disconnected from the metal contactors (8), so that the passage of electric energy no longer occurs, this being the position to be used as a way to avoid electric shocks, even by inserting conductive materials in the holes, considering that the decoupling between the metallic parts disables the passage of energy completely, even inserting metal parts inside the device.

[019] Thus, the present invention is composed of a shockproof socket of very simple construction and highly efficient operation, given that, once coupled to a conventional electrical socket, it no longer needs to have any separate part of the socket, but only a displacement linear movement of the mobile part (2) in relation to the fixed part (1), all in a very practical way and without the risk of the socket being unprotected at any time.
