Definitions
- Connection device for the plug connection of a plug part with a socket part
- the invention relates to a connecting device for the plug connection of a plug part with a socket part, in particular for automatic couplings of rail vehicles according to the preamble of claim 1.
- a connecting device is disclosed in DE-AS 15 63 964.
- Another connecting device is known from DE AS 1 016 736.
- the connecting device described in this document serves for the electrical coupling of the electrical cables of an automatic mechanical coupling of rail vehicles.
- the plunger moved by the guide cone of the mating coupling has a pawl which, during the coupling process, rotates a nose mounted on the main pin with the associated toggle linkage so far in the direction of the coupling until under the action of a compression spring standing toggle linkage has exceeded the dead center position.
- This actuating device initiates the coupling process for the electrical plug-in cable couplings through the counter-coupling, while the actual coupling and holding in the coupled position takes place independently of the mechanical coupling parts of the counter-coupling through the toggle linkage.
- the invention aims to further develop the generic connecting device in such a way that an electrical connection is ensured with a low plug-in force between the plug and socket part - in particular with low electrical resistance even after prolonged continuous operation.
- At least one intermediate element mounted on the plug or socket part and resiliently pretensionable is provided, which is designed such that it engages in a recess formed on the socket or plug side when the plug and socket part are brought together is clamped between the plug part and the socket part with spring tension.
- the electrical connection between the socket and plug part takes place via the intermediate element.
- the spring-mounted intermediate element is preferably designed in a mechanically uncomplicated manner as a pawl which is mounted in the socket part and is pressed against a stop by a spring.
- This jack is expediently and structurally simply supplemented by the fact that the plug part has a stepped shape with at least two stops, such that when the plug and socket part are brought together, one of the stops formed by the stepped shape takes the jack with it and rotates so far that a contact surface of the jack is pressed onto a contact surface before the plug part.
- a clamping effect between the socket part and the plug part can be realized.
- Fig. 4a - b is a schematic diagram of an automatic train coupling.
- Fig. 1a shows a socket part 1, the cross section of which is substantially L-shaped.
- a jack 2 is mounted in the socket part 1 and is pressed by a spring 3 against a stop 4 of the socket part 1. If a plug part 5 is pushed into the socket part 1 in the direction of arrow 6, the first stop 7 of the stepped plug part 5 moves without touching the pawl 2 of the socket part 1. Only a second stop 8 of the plug 5 takes the pawl 2 in the direction of arrow 6 with further movement of the plug part 5 and rotates the pawl 2 so far that its contact surface 9 is pressed onto the contact surface 10 in a recess 11 of the plug part 5 ( see Fig. 1b). The pawl 2 closes within the slot 12 in the storage against the spring 3rd
- the pawl 2 When disconnecting in the direction of arrow 13, the stop 7 of the plug 5 takes the pawl 2 so far that the spring 3 is pulled over the dead center. Thus, the pawl 2 is moved back to the original position - as shown in Fig. 1a.
- the pawl 2 according to FIG. 1 has an essentially bolt-like shape, the region of the pawl 2 pointing away from the slot 11 and facing away from the spring 3 in Direction of the stop 4 is angled.
- the edges of the pawl 2 in the area of the contact surface 9 are each rounded such that the pawl cannot jam when the socket and plug parts 1, 5 are plugged together at the stop 8 and in the recess 11 and engages in the recess 11 in a quasi-rolling manner.
- the embodiment of FIG. 2 differs from the embodiment of FIG. 1 only in that the pawl 2 in its end section, which faces the connector part 5, has a semicircular or hemispherical rounded shape and the recess 11 of the connector part has a corresponding geometry. This further facilitates the unwinding process of the pawl on the plug part 5 and prevents jamming even more reliably.
- the pawl 2 is rod-shaped and particularly easy to manufacture, for example it can be manufactured as a cast part or formed from sections of a rod.
- the complete connecting device can have pawls 2 and corresponding recesses 11 all around, that is to say offset from one another by 60 °, for example.
- the recess 11 can also be formed as a groove running around the plug part 5.
- FIG. 2a shows how the plug part 5 can be easily guided into the socket part 1 in the direction of the arrow 6.
- Both the plug and the socket part 5, 1 are designed so that they are always easily and safely merged when coupling or uncoupling. This is of the utmost importance for the connection device to function satisfactorily since the coupling takes place automatically.
- the pawl 2 When the plug part 5 moves further into the socket part 1, the pawl 2 finally touches the second stop 8, which picks and pivots the pawl 2 when the plug part 5 is further inserted into the socket part 1.
- 2 shows the end position of the pawl 2. In this position, the side region 2s of the pawl 2 lies securely on the stop 8. The movement of the plug part 5 into the socket part 1 is limited in this position.
- plug and socket parts 5, 1 are moved away from each other again (see arrow 6 ') in FIG. 2c.
- the contact surface 9 of the pawl 2 rotates in the recess 11, since the stop 7 supply of the connector part in the direction of arrow 6 '. Finally, it pushes the force of the spring 3 back into the position in FIG. 2a.
- FIG. 3 shows an exemplary embodiment of the invention, which has been structurally simplified further compared to the designs from FIGS. 1 and 2.
- 3 pawl 2 and spring 3 are replaced by a spring-like, elastic component 2 ', such that the functions of the spring 3 and the pawl 2 are integrated in the elastic component 2'.
- the component 2 ' can be designed similar to a plate spring or a toothed disc.
- the component 2 ' has an essentially cone-shaped contour.
- the function of the plug connection according to FIG. 3 corresponds to that of the exemplary embodiments according to FIGS. 1 and 2: when the plug part 5 is inserted into the socket part 1, the component 2 'is elastically deformed, while it springs back into its starting position when the plug connection device is disconnected.
- metal strips are used as elastic components, which are bent at one of their ends around a pin 14, with a flat section 2'b adjoining the curved section 2'a, which section is rounded off in a semicircular section 2'c ends.
- the components 2 ' are punched out of a sheet 23, for example, the gaps in the view in FIG. 3d having a keyhole-like contour.
- the design of the components 2 'in this variant of the invention is characterized by a particularly low design effort and manufacturing price, since there is no need for more complex latch elements 2.
- the section 2'c first passes the stop 7 and then hits the stop 8 with further movement.
- the plug connection is released, it resiliently returns to the position shown in FIG. 3b. This effect is supported by the stop 7.
- 4 illustrates the function of the plug-in device in the case of an automatic pull coupling on the basis of a schematic diagram, FIG. 4 a showing the uncoupled state and FIG. 4 b the coupled state.
- the automatic pull coupling comprises a coupling head 15 with a mechanical coupling center 16, a coupling arm 17 connecting to the coupling head 15 and a coupling joint 18 connected to this. Together with the mechanical clutch, an electric clutch 19 is coupled, which is arranged in an electric clutch frame 20.
- the spring 21 is used for coupling the electric coupling.
- the electric coupling center 22 can be provided with the plug devices according to the invention according to FIGS. 1 and 2.
