Embodiment Construction
[0012] figure 1 A connection core 2a, 2b, 2c according to the prior art for connecting a very schematically shown three-core cable 1 (1a, 1b, 1c), such as a high-voltage cable, with a likewise very schematically shown electrical load 3 Electrically connected devices. "HV" in the figure stands for "High Voltage". Such high-voltage cable arrangements are used, for example, in automobile construction, in particular vehicles that operate or are driven with high voltages. High-voltage electrical energy is supplied by a high-voltage battery (not shown) via supply cable cores 1 a , 1 b , 1 c (also called phases) to an electrical load 3 , for example an electric motor.
[0013] The ends of the cable cores 1a, 1b, 1c are brought together by so-called cable guides 4 such that they are parallel to each other on the same plane and lead to busbars 5 at a specific or standard mutual distance. The busbar 5 is conventionally fastened to the load-bearing base 7 via through holes 6 in fasten...

The invention proposes a connector device for connecting a cable (1), in particular a high voltage cable, with two or more supply cable cores (1a, 1b, 1c) to the joint cores of an electrical load (3) (2a, 2b, 2c) electrical connection, wherein the mutually corresponding ends of the supply cable core (1a, 1b, 1c) and the joint cable core (2a, 2b, 2c) each have an electrically conductive joint element (8 , 9), and wherein the joint elements (8, 9) of the supply cable cores (1a, 1b, 1c) and joint cable cores (2a, 2b, 2c) corresponding to each other are in order to form the respective electrical conductors (12, 13, 14 ), are in electrical contact with each other and are fixedly connected by means of the connecting piece (15) passing through the through hole in the associated joint element (8, 9). Advantageously, the through-openings (10, 11) of the connection elements (8, 9) of at least two electrical conductors (12, 13, 14) to be formed are pierced by a common connecting piece (15), wherein the different electrical conductors Adjacent terminal elements (8, 9) of (12, 13, 14) are electrically insulated from one another.
Description
technical field [0001] The invention relates to a device according to the preamble of claim 1 for electrically connecting a cable having two or more supply cable cores, in particular a high-voltage cable, to a joint core of an electrical load. Background technique [0002] The electrical loads in the vehicle, in particular the electric motor, are supplied externally via so-called high-voltage cables, also called HV cables (HV=Hochvolt), the cores of which are led to the associated busbars of the vehicle The fixed positions arranged at a specific distance from each other, especially the screwed positions. The individual cable cores corresponding to each other are then brought together by the busbar and connected to one another in the screwed-on position described above to form electrical conductors. Busbar arrangements of this type are widely used and well known. In essence, for each conductor at least two mutually corresponding cable cores are electrically conductively con...
