Definitions
- the invention relates to an electrical connector with a plug, which comprises a plug housing with a plug contact receiving part and a plug approach, wherein the plug contact receiving part SteckerANDaufnah men for receiving a main contact pin and additional plug receptacles for receiving a connector auxiliary contact arrangement, and the connector extension comprises the main contact pins and the auxiliary contact arrangements surrounds, and with a socket which comprises a socket housing with a socket contact receiving part and a socket attachment, the socket contact receiving element comprising can contact receptacles for receiving a respective main contact sleeve and additional receptacles for receiving an auxiliary can contact arrangement, and the socket extension surrounds the main contact sleeves and the can auxiliary contact arrangement.
- Such an electrical connector is known for example from DE 296 12 378 U1. It is used in particular to establish the electrical connection between the accumulators of electric industrial trucks such as forklifts or automobiles and control and regulating devices for the drives of the electric industrial trucks or automobiles. Furthermore, this electrical plug connector is used to establish the electrical connections between these accumulators and charging devices for the same.
- the main contact pins and main contact sleeves are used to establish the electrical connection to Transmission of the charging or operating current and the auxiliary contact arrangements of the electrical connection of electrical wires, which are used, for example, to transmit signals between a charging station or a consumer and the accumulator.
- the invention is therefore based on the object of developing an electrical connector of the type mentioned in such a way that it is suitable for transmitting a larger amount of signals or data with unchanged ease of use and unchanged robustness.
- the plug auxiliary contact arrangements and the socket auxiliary contact arrangements now comprise a plurality of wires, in other words they are designed with more poles.
- a plurality of wires for example five wires with a cross-section sufficient for signal or data transmission in a parallel arrangement does not require more space than a conventional, single-pole auxiliary plug contact arrangement.
- the plurality of wires can then, for example, be used for parallel data transmission, or several components, for example a charging station, can be electrically connected to one another in parallel with several components, for example a battery arrangement. In both cases, considerably more signals or data can be transmitted per unit of time compared to a, for example, only two-pole design of the auxiliary contact arrangements.
- the plug contact receiving part comprises exactly two additional plug receptacles and the socket contact receiving part comprises exactly two additional socket receptacles.
- the electrical connector according to the invention is designed exactly as the Conventional electrical connectors described above, so that the conventional plugs and sockets can be used unchanged.
- At least one, preferably both of the plug auxiliary contact arrangements and the socket auxiliary contact arrangements comprises a plug auxiliary contact adapter or a socket auxiliary contact adapter, each of which has adapter extensions that are each received by one of the additional plug receptacles or one of the additional receptacle receptacles and one each Include part of the veins.
- a plug auxiliary contact adapter or a socket auxiliary contact adapter each of which has adapter extensions that are each received by one of the additional plug receptacles or one of the additional receptacle receptacles and one each Include part of the veins.
- plug and socket auxiliary contact adapters have to be mounted by introducing the adapter extensions into the plug and socket additional receptacles instead of the previously single-pole plug and socket auxiliary contact arrangements.
- plug and socket auxiliary contact adapters With the provision of such plug and socket auxiliary contact adapters, it is even possible to retrofit existing electrical connectors of the above-mentioned conventional type by replacing the single-pole plug and socket auxiliary contact arrangements with the corresponding auxiliary contact adapters.
- plug and socket additional receptacles which were previously used to accommodate single-pole auxiliary contact arrangements and which are surrounded by the plug or socket attachment, for now multi-pole auxiliary contact arrangements has the further advantage that this does not increase the volume of the electrical Plug connector goes hand in hand, as is the case, for example, with "piggyback solutions", in which additional auxiliary contact arrangements are attached to the outside of plug and socket housings.
- Such a plug connector is known, for example, from DE 10 2005 037 864 A1.
- At least one, preferably both of the plug auxiliary contact adapter and the socket auxiliary contact adapter has a connection part which includes all of the wires.
- the wires of the adapter extensions are combined in a single connection part.
- the adapter extensions are integrally formed on the connector and extend approximately parallel to each other from this.
- the handling of the respective contact adapter is considerably facilitated in that it can be mounted in a single operation, for example by pushing the adapter extensions into the corresponding additional receptacles of the corresponding contact receiving part.
- connection parts of at least one, preferably both, of the auxiliary plug contact adapter and the auxiliary socket contact adapter are arranged on the side of the plug housing or the socket housing opposite the plug attachment or socket attachment.
- the multi-core cables connected to the plug or the socket for signal or data transmission can then be connected in a particularly space-saving manner.
- the connecting part of a plug or auxiliary contact adapter particularly preferably has a measure for strain relief of the connected electrical cable.
- the measure for strain relief comprises - particularly preferably - a thread with which a mating thread of the electrical connection device provided on the electrical cable can be brought into engagement.
- an external thread is provided on the connection part and the electrical connection device comprises a union nut which can be screwed onto the external thread.
- means are provided for fixing the plug auxiliary contact adapter in the additional plug receptacle and / or the auxiliary socket contact adapter in the additional receptacle receptacle. Due to these means, it is prevented that the corresponding auxiliary contact adapter can move undesirably, for example when plugging the plug and socket, which could possibly hinder contact between the plug and the socket auxiliary contact arrangements.
- the means for fixing preferably comprise a fixing recess or a fixing extension on at least one adapter extension and on the housing a housing extension engaging in the fixing recess or a housing extension in which the fixing extension engages.
- an electrical cable comprising all electrical wires is passed through a bore of the connection part having an inner jacket surface.
- the cable ends inside the connector.
- the wires are divided between the two adapter extensions.
- the cable can have a pre-assembled length that corresponds, for example, to the length of cables connected to the main contact pins or to the main contact sleeves.
- the cable passed through the bore preferably comprises a man tel with an outer jacket surface.
- the outer jacket surface of the jacket is materially bonded to the inner jacket surface of the bore. This creates a particularly reliable fixation of the cable in the drilling of the connector and thus a particularly secure strain relief.
- the material coherent connection is effected by encapsulating the cable with the material of the connecting part.
