Description

The technical field of the invention

This invention relates to the provision of a unified system that contains a German-style hidden wiring socket (CEE 7/4) with grounding, a circular switch with on and off position, located around the socket, and horizontal (in a parallel plane to the bottom of the socket and the wall ) oscillating contact, whereby space and materials are saved.

State of the art

Power connectors are sockets into which a plug is inserted to receive electric current. Household sockets are divided into three types, depending on the application. These are power connectors for hidden wiring, outdoor wiring and power connectors for wet rooms.

Hidden wiring sockets are called power connectors / sockets, in which: external sockets are made of solid PC material, bakelite, thermoplastic with fire retardant property, etc .; external frames are made of plastic ABS material of different colors or as a decorative material; the contact node of the socket is made of ceramic or non-combustible polyamide material; the specified contact node of the socket is connected to electricity; the surface for connection and the outer surface of which is isolated from the electrically conductive connecting terminals to which the wires and their contacts will be attached; The internal mechanism is installed using flush mounting. They are divided into two groups - sockets with grounding and without grounding. In particular, in humid rooms, such as a bathroom, kitchen and appliances, the external parts of which are mostly made of metal, for safety reasons, ground outlets are most often used.

Worldwide, there are three types of applications for widespread household flush-mounted household sockets of various standards. These are the Italian type (CEI 23-16 / VII) of flush-mounted flush-mounted power sockets / connectors, the English type (BS 1363) of flush-mounted power sockets / connectors, and the German type (CEE 7/4) of flush-mounted power sockets / connectors.

The wall box, where the Italian-style flush-mounted socket is mounted, provides a space of 60 × 95 × 45 mm; the box of the socket of the hidden wiring of the English type provides a space of size 68 × 68 × 34 mm, the box of the socket of the hidden wiring of the English type provides a space of 59 × 59 × 32 mm. In Turkey, as in many other countries of the world, a German-style hidden wiring socket is used.

Each removal of the plug inserted into the outlet shortens the usability of the outlet, and this applies to all outlets. Whereas from German-style flush-mounted sockets, it is expected that after 10,000 insertion and removal of the plug, the socket must maintain normal operation (TS IEC 60884-1 Header 21, Normal functioning, page 47, note 4), for electric switches the minimum expected number of operations on and off assigned as 40,000 (TS 4915 EN 60669-1 Header 19, Normal operation, page 41, diagram 17).

Many modern electronic devices, despite being turned off, continue to consume power in standby mode until the plug is unplugged. An increase in the number and intensity of use of such devices in all areas also increases energy consumption. Many people do not remove the plug after turning off the device, and do not insert it again to turn it on again, due to the location of the connectors and the difficulty of inserting the plug again and again.

In the prior art, in order to prevent the aforementioned consumption of electrical energy, on some multi-socket splitters (i.e. extension cords with several outlets), a switch with an on and off position is located to turn off and connect the power supply to the plugs inserted into it. However, when only one device needs to be connected, no user prefers a multi-socket splitter, where the use of a multi-socket splitter is not necessary.

Again, in the prior art, in the utility model document number 2010/03964, entitled “Goliath Type Group Socket with Switch”, the goal was to place a switch on a Goliath type socket instead of a multi-socket splitter to turn off power to the devices. But this invention does not provide a solution for sockets that are used to connect only one device where there is no need for a multi-outlet splitter.

Due to the advantage of free space in Italian and English types of standard flush-mounted sockets, the use of sockets with a switch is common. The large overall dimensions in these types of sockets allow you to freely place a switch on the socket body and use the swing contact design with the location perpendicular to the wall plane, which can be found on all standard switches of hidden wiring. The use of switches on German-style flush-mounted outlets is not preferable because of the small overall dimensions of the flush-mounted zones.

In the prior art, in a patent document entitled “Power Socket with Activation Switch and Operation Method Thereof” under the number 2009/02193, it is disclosed that when said power connector is turned on by an integrated switch, electricity is supplied to a connector plug inserted therein. However, this invention does not provide a solution.

 for German-style flush-mounted sockets.

Again, in the prior art, in a patent document entitled “Switchable Socket” under DE 202005007901 U1, it is disclosed that the electric current supplied to the connector plug can be turned on or off by means of said switch with the on and off position of the outlet. But this invention, which can be used in German-type boxes, does not provide a solution for the English-type sockets in which the plug does not sink into the socket, as in German-style sockets, and which provide the advantage of free space in the flush-mounted area.

In currently used German-style covert wiring outlets with grounding and a switch, the socket and disconnect switch can be used together by proximity. These products not only make full use of the space in the wall, but also prevent large products such as voltage transformers from being connected to the socket because of the switch located next to the socket.

When installing modern German-style flush-mounted sockets with grounding and a switch, the electrical connection is first established with the switch and only then installed with the socket, and therefore creates certain problems associated with this work.

The fact that the design of the swinging contact of modern German-style flush-mounted sockets with grounding and a switch is used perpendicular to the wall plane and is mounted separately from the socket body, contributes to the use of additional housing and connecting parts, as well as labor costs.

In currently available German-style flush-mounted sockets with grounding and a switch, the socket of the socket is shifted to the sides, and the disconnecting switch is located on the front surface, so the socket of the socket cannot be located in the middle section, which gives the product an eccentric appearance.

The currently available German-style flush-mounted sockets with grounding and a switch can only be used with the decorative frame designed for this product, as the socket and switch are located close to the case. This, in turn, creates the need for each series of products with a different design to produce separate forms for the production of suitable frames, which in turn increases costs.

In modern German-style flush-mounted sockets with grounding and a switch, the swing contact design is used vertically; this, in turn, necessitates the installation of an additional contact system next to the mechanism of the socket for hidden wiring to the product. The specified adjacent structure does not allow the use of existing standard steel chassis. The non-use of steel chassis in earthed outlets necessitates the installation of products by screwing on the front side. This leaves the screws around the socket open, and not only the decorative appearance is violated, but also contributes to the need for insulating the heads of the conductive screws remaining on the outside for safety reasons.

A German-style flush-mounted socket with grounding and a switch according to the present invention eliminates the above drawbacks and allows the simple use of a switch with an on and off position on German-style flush-mounted sockets without the need for additional costs and also its application to structures of previous products.

The purpose of the invention

The aim of this invention is to turn on and off the electricity by means of a switch integrated into the housing of German-style covert wiring sockets with grounding.

Another objective of the invention is to achieve added safety by turning off the electricity when the socket is not used, or when devices connected to the socket, if any, are not used, by turning on and off the power supply to the plugs inserted into the German-type buried wiring sockets with grounding using a switch with the on and off position.

Another objective of this invention is to increase the service life of an outlet with grounding by at least 4 times, due to the elimination of the need to insert and remove the plug in the German-type underground wired sockets with grounding.

Another objective of the invention is the elimination of energy consumption by electronic devices that are plugged in but not used, i.e. during standby time, thus saving energy consumption.

Another objective of the invention is to ensure that the installation is completed in a shorter time, in a simpler way and with fewer materials, thanks to a single connection, instead of a two-stage connection, including connecting to the switch during the installation phase of the outlet, followed by connection from the switch to the outlet.

Another objective of the invention is to reduce the total cost of the product by reducing the number of parts used in production and labor by arranging a switch mechanism operating on the principle of a swing contact in parallel to the wall plane and the integrated location of this switch on the housing.

Another objective of this invention is to solve the problem of sufficiently large and wide plugs, for example voltage transformers, with large dimensions to cover the outer surface of the socket, by pressing the switches next to the socket, in German-type buried wiring sockets with grounding, thereby making them suitable for use.

Another objective of this invention is to reduce the cost of additional molds and to ensure their use with all decorative frames by using a very small area around the socket for the on / off function, through the use of a switch mechanism operating on the principle of flipping the contact parallel to the wall plane, and thanks to the integrated arrangement on the case.

Another objective of the invention is the possibility of locating the socket of the outlet in the center and thereby avoiding the eccentric appearance of the product, due to the fact that the functional parts of the outlet with grounding remaining inside the wall do not take up much space, these parts are provided there for the on / off function, as a result of parallel to the wall plane and the integrated arrangement on the case of the switch mechanism, working on the principle of throwing the contact.

Another objective of the invention is to create the possibility of using a standard steel chassis, which is used during installation for products from all series and provides stability due to the switch mechanism operating on the principle of contact reversal parallel to the wall surface and integrated on the housing.

Another objective of the invention is to preserve the decorative shape of the outlet by providing a switch with the on and off position on the front surface of the rounded outlet, so that it will surround the socket of the outlet.

Description of the invention

The invention comprises a circular switch (1) with the on and off position, suitable for turning on and off the electricity supplied to the ground outlet, a handle (1.1) of the switch helping to rotate the circular switch (1) with the on and off position manually clockwise and counterclockwise and at the same time showing the power going to the device is on or off; a switch foot (1.2), moving in a circle around the socket of the socket, the mechanism of contact flipping (11) during rotation of the circular switch (1) with the on and off position clockwise and counterclockwise, the socket (2) of the socket on which the circular switch (1) with the on and off position; mechanism (3) protection for children; a decorative case with conductive properties, while the specified case remains outside the wall and surrounds the outlet with grounding; a steel chassis (5) supporting the internal structure of the outlet, thus supporting it and allowing it to be fixed to the wall by screwing; a light module (6) mounted in the cover (7) of the housing and showing the on or off state of the outlet; a housing cover (7) covering the housing of the outlet with grounding and fixing the internal parts; grounding contact (8), which performs the function of grounding, a switched connecting element (10) of the socket, which transfers current to the plug as a result of connecting the contact end (12.1) of the swinging contact of the socket with the point (10.1) of the contact of the switched connecting element; the connecting element (9) of the socket, the mechanism (11) for flipping a contact moving in the socket (17) of the switch mechanism around the socket of the socket during switching on and off; a swinging contact (12) that rises and falls parallel to the plane of the wall as a result of the movement of the mechanism (11) of throwing the contact up and down in the socket (17) of the switch mechanism; a swing contact holder (13) connected to a cable in which a swing contact (12) is installed and a connection is made to a phase wire; body (14) of the socket.

Figure 1 shows an exploded isometric perspective view of a German-style hidden wiring socket with grounding and a switch. Installation of the product is carried out alternatively from the bottom up, the parts are attached using screws (16), rivets (15) and connecting elements in the form of latches (parts made with elastic snap elements).

When connecting electricity to German-style covert wiring sockets with grounding, the neutral wire connects to the connecting element (9) of the socket, the grounding wire connects to the grounding contact (8) and the phase wire connects to the swing contact holder (13) connected to the cable using bolts and nuts secured there by tightening.

The pins of the German-type electric plug with ground (CEE 7/4) are connected to the connecting element (9) of the socket and the switched connecting element (10) of the socket, and a ground connection to the grounding contact (8) is achieved.

The circular switch (1) with the on and off position of the German-style flush-mounted socket with grounding is rotated clockwise with the handle (1.1) of the switch and thus turns on, i.e. takes the position In figure 5. During this action, the handle (1.1) of the switch rotates clockwise and rotates the foot (1.2) of the switch in a circular direction clockwise. With this circular movement of the switch leg (1.2) in the switch leg socket (11.2), the contact flip mechanism (11) rotates clockwise in the socket (17) of the switch mechanism around the outlet socket. During this movement, the spring in the case of the contact reversing mechanism (11) first compresses and then expands, while continuing to apply the pressure applied by the contact pin (11.1) of the contact reversing mechanism to the swing contact (12). As a result of this pressure, the right side of the oscillating contact (12) is lowered down, and then the contact end (12.1) of the oscillating contact is connected to the contact point (10.1) of the switched connecting element of the socket, thereby allowing electric current to pass to the switched connecting element (10) of the socket. Thus, the electric current passes to the switched connecting element (10) of the outlet; In this way, electric current is transferred from the outlet to the plug.

The circular switch (1) with the on and off position of the German-style flush-mounted socket with grounding rotates counterclockwise with the handle (1.1) of the switch and thus turns off, i.e. takes position A in FIG. 5. During this action, the handle (1.1) of the switch rotates counterclockwise and rotates the foot (1.2) of the switch in a circular direction counterclockwise. With this circular movement of the switch foot (1.2) in the switch foot (11.2) of the switch foot, the contact flip mechanism (11) rotates counterclockwise in the socket (17) of the switch mechanism around the socket receptacle. During this movement, the spring (11.3) in the case of the contact reversing mechanism (11) first compresses and then expands, while continuing to apply the pressure applied by the contact pin (11.1) of the contact reversing mechanism to the oscillating contact (12). As a result of this pressure, the left side of the oscillating contact (12) falls down and the contact end (12.1) of the oscillating contact and the contact point (10.1) of the switched connecting element of the socket are separated from each other. Thus, the electric current does not pass to the switched connecting element (10) of the outlet; thus, the transmission of electric current from the outlet to the plug is blocked.

When connecting the swinging contact end (12.1) of a German-style flush-mounted socket to ground with the contact point (10.1) of the switched connecting element of the socket, an electric current passes to the plug and light module (6) located on the cover (7) of the housing. Thus, when the German-style flush-mounted socket is connected to ground, the light module (6) is already connected to the socket connecting element (9), and the switched socket connecting element (10) also turns on. The light of the LEDs on this light module (6) is emitted vertically upward, experiences refraction and dispersion inside the circular switch (1) with the on and off position made of transparent and light-conducting material, and thus the user sees the light in front of the outlet when it is turned on mode (Fig.5.A).
