    The plug-in and plug-out operation is associated with high power consumption in the case of electrical plugs designed for high-current load. It is therefore the object of the present invention, weaker or one-armed disabled persons to facilitate the quick charging at Stromzapfsäulen in a simple way. A solution to the problem is made possible by the present invention by the cylindrical configuration of the electrical contacts (5, 6), so that the electrical connector (1) in each position in the corresponding electrical socket on and - can be unplugged. According to the invention contact during this process, the contacts (5,6) of the electrical plug (1) and electrical socket only weak, so that no force is required. In contrast, during charging via a pneumatic valve system by an expansion bellows (12), the electrical contacts (5, 6) of the electrical connector (1) against the electrical contacts (5, 6) of the electrical socket pressed, resulting in the necessary good contact and a tight fit in the electrical socket results. The completion of the charging process by releasing the excess pressure from the expansion bellows (12) by means of a on the electric plug (1) located ventilation button (8th).

    专利说明:

    The invention relates to an electric plug with socket, suitable for high currents, preferably for charging electrical energy harvesters powered by electrical energy vehicles, which are due to the requirement of Sehne1ladung and therefore necessary high current flow, the electrical contacts over a large area and for secure contact additionally mechanically , Especially by pneumatic expansion of a bellows (expansion bellows) are pressed against the mating contacts of an electrical outlet. As a result, a second aspect according to the invention, namely the safeguard against unintentional release of the electric plug during the charging process from the socket, becomes effective.
    From WO 2011/157841 Al a fuse of the plug in the socket by a mechanical lock is known.
    A suitable pneumatic device of the connector controls the expansion state of the bellows during insertion and removal, as well as in the state of current flow * This means that only during the charging process, the bellows is expanded and pressure is exerted on the contacts. As a result, a problem that usually occurs in large electrical plugs, namely that due to the clamping effect of the resilient contacts considerable force is necessary to operate circumvented and another of the invention inherent advantage is given, namely the weaker persons allowed to operate the plug effortlessly.
    Another essential development of the invention is that the current flow is released only when the plug is completely inserted into the socket. For this purpose, it is necessary that the plug bases is approached to the correspondingly shaped counter area of the socket so far that either via a sensor z. B. optically or magnetically a relay is controlled, which allows the Stromflüss, alternatively by mechanical actuation of a switching contact. A further control possibility of the current supply and disconnection can take place via an adjustable gas pressure switch connected to the gas line leading to the bellows,
    Which mechanically actuates a current pushbutton which, when activated, can be used
    Bellows is expanded, which connects plug contacts with the charging cables. Frequently, gas pressure switches are used which have built-in switching contacts, which produce the connection directly to the contacts when the predetermined setting pressure is reached, or cause this via the activation of a relay,
    A corresponding socket for the inventive embodiments of the electrical connector is characterized in that it has to the plug suitably shaped contacts, which by their arrangement, the high pressure of the plug contacts, which is exerted during the charging process by the bellows on the contacts withstand. This is achieved by supporting the central contact against the inward pressure of the inner plug contact by a pressure stable portion of the socket. The outer socket contact abuts against a tubular plastic carrier, which on the outside of a thin-walled steel cylinder protects against the outward pressure of the outer plug contact.
    A charging station for energy collectors which is suitable for the application of the electrical connector according to the invention must also have a connection for compressed air in addition to the components required for the charging operation, since only the compressed air caused by expansion of the bellows makes a secure contact, and the power supply is activated.
    The switch-on point for the beginning of the electrical charge is given by an adjustable gas pressure switch in the plug, which is connected to the compressed air supply line on the bellows. The charging process can be started without switching functions at the electric pump, due to the characteristics of the plug according to the invention. The completion of the charging process can be done at any time by hündische actuation of the vent valve and removing the plug from the socket. So it is in the simplest case of the application of the invention to perform no switching function on the Stromzapfsäule. 2 3/22
    In another way of handling the charging plug, after it is plugged into the socket, compressed air and power to the power pump on and. -Stopped * After delivery of a selected amount of charge or full charge, if there is a corresponding electronic devices in the Stromzapfsäule, be turned off by this power and compressed air supply.
    In the described embodiments of the charging connector actuation of the vent valve in the plug is necessary to safely remove the residual pressure in the bellows. Then the plug can be plugged in or removed from the socket.
    In all embodiments of the invention, the assurance that no current can take place before the electric plug is fully inserted into the socket, characterized in that a gas pressure switch registers the gas pressure in the bellows, does not make contact with the charging station until the set gas pressures in the bellows reached is.
    The switch-on is carried out via the control of the gas supply such that when inserting the plug of the plug base the central middle part of the socket according to the invention is so far approached that thereby the GasschieberansatzeS is pushed into the plug body and the valve piston releases the gas flow. After reaching the predetermined pressure in the bellows, the gas pressure switch switches off the power to the plug contacts via a high current relay. A shutdown before a desired full charge or Stromäbgabemenge is done, can be made by the ventilation valve is operated on the erfindüngsgemäßen plug, thereby reducing the pressure in the bellows, the gas pressure switch turns off the power supply from. As the overpressure drops, the pressure of the bellows stops on the plug contacts, which can easily pull the plug out of the socket. A spring in the throttle valve pushes the control piston to the starting position, which prevents the supply of compressed air. In the application of premature termination of the charging process, the possibility / on the pump to shut off compressed air and power, and then pull the venting valve on the plug to pull it out of the socket. * ··· ···· ♦ ··································································································· Concerning the charging of energy collectors at an electric fuel pump, criteria similar to refueling of a liquid fuel dispenser are expected, such as safe and easy operation and short stay.
    These requirements are met in the invention described by the following advantageous functions, effects and properties:
    The cylindrical embodiment of the electrical contacts preferably embodied in the invention enables large contact areas and thus high currents. By this shape of the contacts and any insertion position between 0 and 360 ° to the connector axis is possible, so you must not pay attention to a specific connector position, which contributes to the simplification of the operation.
    For secure contact in the plug according to the invention, the plug contacts as soon as the plug is fully inserted into the socket, pressed by a pneumatic-mechanical arrangement ah the contacts of the socket. This is at the same time causes the plug is held firmly in the socket and pulling out during the charging process is practically impossible. This fuse is necessary to ensure a high contact surface while the charging current flows, since if the contact surface is too small, the contacts could burn off.
    An essential aspect of the invention is therefore given by the fact that a current flow is allowed only when the plug is fully inserted into the socket and thus automatically by the expanded bellows a large-scale Kontaktschluß is given.
    Advantageous for the handling of the plug further proves that the contact pressure necessary for a secure contact is not reached by the clamping spring action of the contacts, but is achieved by the pressure of the inflated bellows and erf indungsgemäß by venting the bellows of the pressure on the Contacts can be lifted. As a result, the process of plugging in and out is also feasible for less powerful people. 4 5/22
    The construction of the electric plug has a one-piece cylindrical housing made of impact-resistant plastic, which includes an area for receiving the plug body, in which the electrical contacts for the load, the slide system for the compressed air control, the adjustable air pressure switch, the vent valve and the contact portion with the contacts and the expansion bellows are implemented, further a handle portion ergonomic dimensioning, through which the electrical leads to the contacts, the gas pressure switch and the compressed air line to the valve are guided. For mechanical securing of said lines a suitable for the electrical connector clamping device is provided in the region of the cable entry into the handle.
    The electrical lines and the compressed air line are to protect and to prevent the ingress of moisture into the plug, surrounded with a shrunk onto the plug handle thin-walled hoehflexibleh hose. The preferred embodiment of the electrical connector according to the invention is dimensioned in the accompanying drawings similar to a 32 A power plug and designed for a power of 30 kW and currents up to 600 A.
    Embodiments of the electric connector according to the invention for higher or lower powers, or the split version of the connector housing, can bring advantages depending on Anwendungsfal1 and are easy to perform. Alternatively to the use of the attached at the charging station described here electric plug this can also be attached to a lead on the electric vehicle and be plugged with a socket located at the charging station.
    With reference to the accompanying drawings of the electrical connector, its implementation and function will be described in the preferred embodiment:

    The socket body (27) made of dimensionally stable plastic carries both the outer socket contact (28) and the inner socket contact (29). The outer tubular part of the socket body is surrounded by a tight-fitting steel cylinder (30).
    The function of the electric plug shown in the unplugged state is described with reference to the sectional views of FIG.
    The expansion bellows (12) is due to its formation in this situation in the contracted state, since the valve piston (17) blocks the gas supply to the bellows.
    Consequently, no pressure is exerted on the outer (5), (28) and inner contacts (6), (29). This makes it effortless
    Plugging into the socket (26) guaranteed.
    This state continues as long as not by the insertion, wherein the central part of the socket body (27) the approach of the valve piston (18) in the plug body (11) zurückt.und thus the valve piston (17) the gas flow to the bellows (12). releases.
    When the plug is fully inserted, the gas filling of the bellows (12) begins, whereupon it expands and both the inner (6) and outer (5) plug contacts are pressed against the contacts of the socket (28), (29). After the intended pressure in the bellows is reached, the built-in gas pressure switch (23) contact is closed, via a relay line (4) actuates the relay in the Stromzapfsäule and thus turned on the charging current.
    The completion of the charging process can be initiated directly from the plug (1) by pressing the vent button (8) opens the vent valve (15) and the pressure from the bellows (12) drained, while the gas flow is shut off and the contacts of the plug ( 5) (6) no longer be pressed against the contacts of the socket (28) (29).
    At the same time, the gas pressure switch (23) shuts off the power supply to these when falling below the switching pressure via the relay in the Stromzapfsäule, which makes contact with the charging cables. 9 10/22
    Now the plug (1) can be easily pulled out of the socket (26). The Kölbenäusrückfeder brings (19) the valve piston (17) in the shut-off position.
    The charging process on a Stromzapfsäule will run in many cases similar to a fuel dispenser, where the fuel supply to detect the reaching of the tank filling and the fuel supply is stopped. In the case of an electric filling station, power supply and compressed air are switched off just after delivery of a certain amount of electricity.
