The invention relates to a network plug-in connector to connect a network cable to the socket with earthing contact, with the body of the plug and the plug part which is placed in the rod connector plug connected with a network cable.

The mains plug connector type considered here known as the contour plug or in the absence of a grounding contact plug. With it the device of protection class I and II are connected to the electrical network. The plugs are re-connected, or if no reconnection run fully isolated plastic. Typical applications plug it devices such as for example, radio, lamps, vacuum cleaners, etc.

In the case of known network connectors cable is removed from the housing preferably at right angles to the plug-in fork (so-called angle plug connector).

At the transition between the housing and cable they have a device that prevents the loss of longitudinal stability, which should protect the cable from damage. Known network connectors are often removed from the socket for the cable. Thus on the cable there is a very large force, which, despite the device, preventing loss of longitudinal stability, can lead to damage inside the plug once the EMA. Such damage often items on the outside and when you re-insert the plug into the outlet are dangerous, for example, short circuit, etc.

To resolve this issue from the patent DE 102006029927 A1 is known a lever that when removing the connector for the cable that pushes the plug out of the socket. A disadvantage of the known network of plug connectors is that the lever is in the interval plugs and plug by pulling the cord is out of the plug connector and rests on the bottom of the socket. Thus, the known network plug connector can only be used for solutions that between the plug and the plug is not placed important for the functioning parts, such as contact with the ground. In addition, the network connector does not solve the problem of having enough effort during normal pulling the plug needed to extract it from the socket as the plug is very firmly seated in the socket, which can be difficult, particularly for older people. Support motion extraction is carried out only when improper unplugging of the connector for the cable.

In this case, the present invention eliminates this disadvantage. The basis of the invention is the purpose of such modification of a network of plug connectors of this type that is damaged is I was not permitted even when removing the plug for the cable and simultaneously decreased requirements for applied effort when removing the plug from the outlet. In accordance with the invention this task is solved by the fact that the main part is located on the housing of the connector with the possibility of rejection, and that the body of the plug has a cross member with a focus outside of the recess of the socket with earthing contact.

Using the present invention provides a network plug connector to connect a network cable to the socket with earthing contact, in case of extraction of the plug for the cable prevents damage to the plug. This is due to the fact that the main part fixed to the body with the possibility of rejection. As a result, when pulling the cable mainly in the axial direction of the plug plug plug yields, which prevents overloading the connection between the network cable and plug. Simultaneously with this pulling cable cross-bar based outside the recess of the socket, allowing additionally supported pulling motion, which prevents damage to the connection between the network cable and plug. In addition, due to the possibility of rejection of the body of the plug relative to the plug part and the possibilities it stops provided on the chassis cross member even when the normal extraction of the plug from the socket to the desired pressure force is significantly reduced. This significantly eases izvicinaties from the outlet, especially for older people. In addition, the account provided on the chassis cross member plug network connector remains unchanged compared to standard plugs, so plug in accordance with the invention can be used in all known variants of the network Jack.

In the modification of the present invention the possibility of rejection is implemented using anchor bolts, which are accommodated in the housing and the main part. The use of anchor bolts offers a simple and reliable form of security possible deviations.

In another modification of the invention the main part placed Rethimno with the case. This allows you to reconfigure the network connectors with regard to relevant national characteristics in the manufacture of plugs. With this event comes at a high flexibility in the production network plug for different countries.

Selected as an example, the network plug connector 1 for connecting the network cable 2 to the outlet 3 with the ground contact comprises a plug part 4 and the housing 5 of the connector. In the plug part 4 are rods 6 plug plug. Network plug connector 1 includes a compartment 7 for the connection cable, which is connected to the plug part 4.

Connector part 4 consists of a main part 41. The main part 41 has the contour of traditional eurostate and during normal operation of the network connector 1 retracts into the provided recess 31 of the socket 3 with ground contact. Through the main part 41 are rods 6 plug plug protruding from the main portion 41 at the opposite housing 5 of the connector side. Between terminals 6 plug plugs into the main portion 41 parallel to the rods 6 plug plug is a rivet 42. In addition, in the main part 41 in a known manner provides a ground contact 43.

Connector part 4, in turn, has a known manner by the at the perimeter of the slots 44, which serve to exit the ground contact 43. Similarly provided offset from the slots 44 90 degrees guides 45 on the perimeter of the plug part 4, which when inserted into the socket 3 are located there guides. In addition, the perimeter of the plug part 4 next to the guides 45 are the channels 46, which is at right angles to the longitudinal middle line of rods 6 plug plug. In facing the housing 5 of the connector area on the facing network cable 2 side at the plug part 4 made the projection 47, which is smaller compared to the main part 41 of the diameter.

The housing 5 of the connector has a base 51 on which at one end is provided a compartment 7 for cable connection. The base 51 is closed by a cover 52. Between the base 51 and the cover 52 is formed a cavity through which establishes connection of the network cable with 2 cores 6 plug plug. Based on 51 in the area of the plug portion 4 is located the slot 53 of a support consisting of two essentially semicircular jaws 54. Cheeks 54 have openings 55 in assembled condition, are in line with the channels 46 in the plug part 4. The connection between the plug part 4 and the housing 5 of the connector is carried out using anchor bolts 56, which through holes 55 are inserted into the channels 46. Plates 54 are components of passes p is the perimeter of the knob 57, located on the base 51. The knob 57 corresponds to the protrusion 47 of the plug part 4.

The housing 5 of the connector is on the opposite network cable 2 side of the crossmember 58, protruding from the plug part 4. In the embodiment, the cross member 58 is implemented in a simple way by lengthening the base 51. When plugged into the outlet 3 state of the connector 1, the cross member 58 abuts against the outside of the recesses 31 of the socket; in the embodiment, the cross member 58 abuts against the frame 32 of the socket 3.

When plugged into the outlet 3 the state of the network connector 1 (figure 4) connector part 4 retracts into the recess 31 of the socket. While the base 51 is partially covers the frame 31 of the socket 3. For a regular network retrieval of the plug connector 1 from the outlet 3, the corresponding user is taken to the body 5 of the connector between the plug part 4 and the cover 7 for cable connection or directly over the compartment 7 to connect the cable and makes essentially parallel to the direction of the rods 6 plug sockets movement. This movement causes deflection of the housing 5 of the connector relative to the connector portion 4 formed around the anchor bolts 56 axis. Thanks to the ledge 47 of the knob 57 prevents this deflecting movement.

Because the axis deviation between the plug part 4 and the housing 5 of the connector is located on the elongation prodelin the y axis rods 6 plug plug, and on the opposite the point of application of effort the user side of the reference axis provided by the cross member 58, the deviation around the reference axis leads to the emphasis of the cross member 58 out of the recesses 31 of the socket, in the example implementation on the frame 32. As the cross member 58 constitutes the outermost point of the housing 5 of the connector, the housing 5 of the connector also moves along the longitudinal axis of the rods 6 plug plug in the area of the support bolts 56 so that the housing 5 of the connector partially departs from the recess 31 of the socket. This movement continues until the connector part 4 is not completely depart from the recess 31 of the socket. Thanks to lever action when pulling the housing 5 of the connector in the compartment 7 to connect the cable and spaced far enough away from him the fulcrum of the housing 5 on the frame 32 is greatly reduced the effort to retrieve the mains plug connector 1 from the outlet 3.

In the case of noncompliant operation of pulling the network cable 2 to retrieve the mains plug connector 1 from the outlet 3, there is a similar effect. In this case, due to the cross member 58 of the lever also causes a reduction in effort to extract the plug. Due to the small effort required is significantly reduced damage due to improper plug pulling the network cable.
