Definitions
- the present invention relates to a device for connection of a power bar to a electrical conduction.
- the present invention relates to such a device which makes it possible to connect a power bar connected to an electronic circuit power, arranged in a housing, to a conduction member electric, external to the housing, via connecting connector means arranged on the outer face of a wall of the housing.
- clamping means comprise for example a screw-nut mechanism, adapted to be engaged in corresponding holes of these parts to fix them and connect to each other.
- devices of this type have a certain number of drawbacks, particularly in terms of their tightness, on the one hand to humidity and on the other hand to heat and mechanical stress transmitted by the bar to the electronic circuit.
- connections are made by cables copper electrical for example, insulated and cross-section important, at the end of which are crimped or brazed metal lugs.
- connection of these terminals at the battery or traction motor is a good technique known.
- This power chopper is made up of components power electronics assembled on a circuit printed according to known technology.
- This printed circuit is connected to the rest of the vehicle circuits by power bars.
- the current flowing in this chopper and the power bars can be for example of the order of 300 amps.
- the object of the invention is therefore to resolve these problems.
- the invention relates to a device connection according to claim 1.
- Figure 1 a device of connection of the state of the art, a bar of power designated by the general reference 1 on this figure, connected to a power electronic circuit 2 arranged in a housing 3, to an electrical conduction member, external to the housing and designated by the reference general 4, via connector means of connection, designated by the general reference 5.
- connection means are arranged on the face external wall of this housing 3.
- the housing 3 has a conventional structure of receiving for example a printed circuit board from power, on which portions are fixed or welded connection for example the, from the power 1.
- connection connector means At one end corresponding to an electrical cable with a large cross-section, constituting the electrical conduction member 4 described previously.
- connection device which makes it possible to connect a bar of power, designated by the general reference 10 on these figures, connected for example to an electronic circuit of power arranged in a housing, to a conduction member electric, designated for example by the reference general 11 in these figures, external to the housing, by by means of connection connector means, designated by the general reference 12 on these figures, and provided on the external face of a wall of the housing, this being designated by the general reference 13 in these figures.
- the connector means include next to a passage 14 of the housing 13, a cavity 15 adapted to receive sealing means 16 and a connecting piece 17, made of insulating material.
- This connecting piece 17 is fixed to the corresponding wall of the housing, for example via screwing means 18 and 19 (Fig. 5) which will described in more detail later.
- this connecting piece 17 is provided with a housing 20 for receiving the corresponding ends of the electrical conduction member 11 and of the power bar 10, which extends across the passage 14 of the corresponding wall of the housing 13 and the sealing means 16, and clamping means 21 of these ends of the member and of the bar, to fix and connect these to each other.
- the imprint 15 formed on the external surface of the corresponding wall of the housing 13, has a seat-shaped portion, designated by the reference general 22 in this figure, provided around passage 14 of the housing wall and adapted to cooperate with sealing means 16.
- sealing means are presented by example in the form of a ring or a washer in neoprene or other material, provided with a passage for the end matching the power bar 10 like this has was previously described.
- the connecting piece 17 is fixed to the wall of the housing 13 by means of screwing means 18 and 19 (Fig. 5).
- the clamping means extending into the housing 20 of the connecting piece 17, include as as previously stated, a screw-nut mechanism designated by the general reference 21.
- This mechanism includes a screw designated by example by the general reference 23 in these figures, this screw being adapted to be engaged in a hole corresponding side 24 of the connecting piece 17 and to cooperate with a nut 25, for example a prisoner in the housing 20, after having passed through this housing 20 of the connecting piece transversely.
- the electrical conduction unit designated by the general reference 11 can for example be presented under the shape of an electric cable whose end is provided of a terminal 26.
- the corresponding ends of the power bar 10 and this terminal 26, can be provided with holes 27 and 28 respectively, for the passage of the screw 23 of the screw-nut mechanism of the means tightening 21.
- the part connection 17 is fixed on the corresponding wall of the housing 13 by means of the screws 18 and 19, of so as to compress the seal 16 between this connecting piece 17 and the seat-shaped portion 22 of the corresponding imprint of the wall of the case.
- the corresponding end of the bar power 10 crosses passage 14 of the corresponding wall of the housing 13 and the seal 16 and extends in the housing 20 of the connecting piece.
- the corresponding end and more particularly the terminal 26 of the electrical conduction member 11 external to the housing, is also engaged in this housing 20 of the connecting piece, so that the holes 27 and 28 of these exhibits, on the one hand opposite one on the other and on the other hand opposite hole 24 of the screw 23 of the clamping means 21.
- the power bar 10 can be fixed on a printed circuit board, arranged in the housing 13 in a conventional manner, for example by welding of corresponding studs thereof, as has has been described with reference to Figure 1.
- connection device has a number of advantages over to devices of the state of the art.
- these power bars are immobilized along the three axes. In addition, these are electrically isolated from the housing.
