FR2498830A1 - Mains safety socket design to prevent electrocution - has sliding wedges which cover socket holes when plug is not engaged - Google Patents

Abstract

The receptacles of the safety socket are automatically blocked by sliding insulating wedges. When the plug is not inserted. The prongs of the plug fit through the holes of a secondary plug which has a large central pin made of insulating material. The central pin forces aside the sprung loaded wedges in which the holes for the passage of the plug are now aligned with those of the socket. When the plug is inserted, the edge of the insulation on the prongs moves beyond the surface of the socket before the metallic plug tips make electrical contact. Recesses in the central pin allow it to be held firmly in the inserted position by the wedges. The design prevents objects being accidentally or deliberately inserted into the socket holes.

Description

The present invention relates to a set of a female electrical outlet with or without earth connection and a male plug with semi-insulating pin with or without earth connection
In this area, there is no total safety device which makes it possible to avoid any source of electrocution accident, in particular for children. The existing protections currently leave a possibility of canceling them by the introduction of a metallic part, any conductive, in the hole or holes of the socket.

The problem to be solved consists in making a simple total safety device on the female socket, device only controlled by a push pin, adaptable on the inhaled plug.
The present invention has as its object to prevent any person or child from introducing any metallic conductive object into the receptive sockets of the socket, that it does so voluntarily ocl involuntarily; this thanks to a closing device automatic in the female socket This device can only be controlled by the push pin adaptable on the pins of the male plug
Figure 1 is a front view of the male plug with its 2 semi-insulating pins.

FIG. 2 is the following section DB of FIG. 5, of the adaptable push pin.
Figure 3 shows the exploded section of the parts of the safety mechanism mounted on the socket
Figure 4 is the section of the socket and plug half interlocked, having released the security system.

 Figure S is the bottom view of the push pin Figure 2, showing the adapter system on the male plug.

Fig. 4 shows the half-plugged sockets and the unlocking of the total security theme sys which is unlocked, without however the current passing
The plug 1 comprising the 2 semi-insulating conductive pins 2 on which the push pin 3 is adapted by the automatic retightening system 12, is inserted into the holes of the cover 5
The curved or rounded tip of the push pin 3 has separated the 2 safety drawers 7 by compressing the 2 return springs 6, in order to set the passage holes of the pins 2 and allow the introduction, n n.

these in the receiving sockets 11
In this first position, it can be seen that the electrical contact between the pins 2 and the sockets 11 is not yet ensured. It is also noted that the part is) lee of the pins 2 is already engaged in the cover 5; which sets up the second security
This cover fixed on the socket body 10 by the fixing means 4, serves as a guide for the drawers 7
The 2 receiving sockets 11 are fixed on the insulating body 9, itself fixed to the body of the socket 10 by the fixing means 8 The body 9 also serves as a guide for the drawer 7
When the male plug 1 is fully inserted, the pins 2, engaged in the sockets 11, ensure the passage of electric current The notches 3A of the push pin 3 engaged at the ends of the 2 sliding drawers 7, serve to effectively hold the male plug 1 in socket 10
The device, object of the invention, can be used in all electrical installations of buildings or other, domestic or industrial.

and in all electrical connections including sockets, this in order to respect the safety requirements required by applicable laws
