Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a current connector for a multipole conductor which is guided in a casing, for example an electric rotary joint consisting of a stator and a rotor, more particularly in the area of the casing wall of the conductor. It concerns an electric current connector which is connected to an external power source or a conductor guided to the consumer.

[0002]

BACKGROUND OF THE INVENTION Current connectors of this kind are used, in particular in motor vehicles, for electrically connecting the connections of a rotating conductor coupling provided between the steering wheel and the steering column. In this case, in addition to a large number of functions, for example, a signal horn of the traveling direction display member and a wiper, when a large number of functional parts are controlled from the steering wheel, or when an airbag collision protection device is further incorporated, Such a connector has a big problem. In the case of known connectors of this kind, the conductors to be connected are provided with bushings or pin plugs or are brazed directly to one another. In this case, in particular, the connecting method must already be determined when the connecting element is manufactured. That is, the user is bound by the connection method set by the manufacturer, or the manufacturer has to make a number of different connectors and keep them in stock.

[0003]

SUMMARY OF THE INVENTION The problem underlying the present invention allows for a greater standardization of production, where the producer or user selectively adapts the connecting element later to a bayonet or brazed joint. It is to provide a current connector that can be easily manufactured.

[0004]

This object is achieved in that the connector is formed by a bush and a plug, each free-standing holding a tubular pin connected to a conductor, the plug having the same inner dimensions as the bush. The problem is solved by having insert-in pins in the form of a casing with outer dimensions, which can be fitted into the tubular pins and which are connected respectively to a conductor plate, in this plug.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention having the features described in the claims will be described in more detail with reference to the accompanying drawings.

[0006] A multi-pole conductor 3 guided in the casing, for example, in an electrical rotary joint consisting of a stator 1 and a rotor 2.
The current connector shown in the figure for connecting the two connections provided in the stator 1 or the rotor 2. This connection is connected to the power supply or the consumer by means of outer and inner conductors, respectively. The connector comprises a bush 4 holding a tubular pin 6 free-standing (freely or without auxiliary means), as can be seen in particular in FIGS. The end pieces of this tubular pin each form a conductor 5. The bush serves for accommodating a plug in the form of a casing 8 with lid. This lidded casing has an outer dimension which corresponds to the inner dimension of the bush 4. In the casing with a lid, insertion pins 10 that can be inserted into the tubular pins 6 and that can be connected to the respective lead wires are held.

The elements of the connector according to the invention can be mounted in any state of manufacture of the electrical rotary joint element, so that the final preparation can be staggered until the point of final assembly, depending on the respective technical requirements, The connection can be made by direct brazing or bayonet fitting if desired. To do so, simply attach the bush by pinching and fixing or brazing the conductor wire 5 to the tube pin 6, clip the plug 8 or 9 to the mating conductor 7, and combine it with the unit shown in FIG. Only needed. In this case, the bayonet pin 10 may be attached to the casing as a separate element, or if the thickness is sufficient, it may be formed by the exposed conductor itself, with the insulation removed.

The casing of the stator 1 or of the rotor 2 preferably comprises a housing for holding the bush 4 or the plugs 8, 9 in a frictionally connected or complementary manner. Further, the casing 8 and the casing lid 9 are connected to each other by the film hinge 12, and the clip locking member 1
3 and 14 are provided. This greatly simplifies the mounting on the corresponding conductor end. It suffices to insert the conductors into an open casing, connect the conductors with the insulation partially removed to the bayonet pins, fold back the film hinge 12 and then clip the lid 9 onto the casing 8.

An insulating web 16 or a separating web 17 is provided in the bush 4 and the plugs 8 and 9. These webs ensure an electrically insulating retention of the conductors and at the same time act as an insertion limit, whereby the insulating web 16 and the bushes themselves strike the separating web during assembly of the parts, which limits the insertion depth. , And forms a current flow portion to the transmission path connected to the adjacent conductor.

Required in the case of this type of current conducting connector
By being able to attach the anti-bow deforming member 18 directly to the plugs 8, 9, the production and the assembly which is nowadays very expensive is greatly simplified.

[0011]

As described above, the current connector of the present invention allows for greater standardization of fabrication and allows the manufacturer or user to later selectively fit the connecting element to a bayonet or braze joint. Has the advantage that it can be done easily.
