Arrangement for high voltage components located in a motor vehicle

Abstract

An arrangement for high voltage components located in a motor vehicle, which has a housing for receiving the high voltage components, is completely lockable, conductive and suitable for electromagnetically screening the high voltage components. The housing has openings for electromagnetically compatibly connecting electrical lines to the high voltage components. The housing consists of plastic material which has been rendered electrically conductive by the addition of metallic particles, and has at least on one of its walls at least one support element for the same. The housing is manufactured of the plastic material filled with metallic particles by injection molding, in the shape being adapted to the spatial configurations of the location of mounting in the motor vehicle.

Claims

1. Arrangement for high voltage components present in a motor vehicle, comprising: a housing for receiving the high voltage components, wherein said arrangement is completely lockable, and wherein said arrangement is electrically conductive and suitable for electromagnetically screening the high voltage components arranged in the housing, and wherein said arrangement has a box shape lower part having a bottom and four walls arranged on a bottom, wherein the surface area of the bottom is larger than the enclosed surface of the walls, a protending edge of the bottom being used for obtaining a conductive connection with the chassis of the motor vehicle, wherein the housing has in the bottom at least a further collared sleeve or threaded box to fasten the housing on the motor vehicle part and for contact with the chassis by means of screw, wherein the walls of said arrangement have openings of different types for electromagnetically compatibly fastening electrical lines to the high voltage components, wherein the housing is composed of plastic material, which, through the addition of metallic particles of any one of steel, copper, tin or a combination thereof, is rendered electrically conductive, wherein the housing has on its walls at least one support elements which mechanically stabilize the same, said support elements having a triangular shape, and wherein the housing is manufactured with the plastic material filled with metallic particles through injection molding into a shape having any desired configuration.

2. Arrangement according to claim 1, wherein the wall thickness of the housing is between 1 mm and 4 mm.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) An embodiment of the invention is illustrated in the drawings.

(2) They show:

(3) FIG. 1 a perspective view of the housing in accordance with an embodiment.

(4) FIG. 2 the housing according to FIG. 1 in the open state.

(5) In the drawings the same numbers correspond to the same technical features.

DETAILED DESCRIPTION

(6) In FIG. 1 a housing 1 is shown for high voltage components. The housing 1 consists essentially of a box shaped lower part 2 and a cover 3. In FIG. 2 the cover 3 and the lower part 2 are illustrated separately for clarity's sake. The illustrated example serves to illustrate the invention. As already mentioned, the housing 1 may advantageously have any chosen configuration.

(7) The box shaped lower part 2 consists of a bottom 4 and four walls 5 which are arranged in accordance with a right angle ground plan on the bottom 4. Of course the ground plan and the walls can have any configuration. The surface area of the bottom 4 is larger than the enclosed surface area of the walls 5. The all-around protruding edge 6 of the bottom 4 can, for example, be used to secure the housing 1 within the motor vehicle and/or for obtaining a conductive connection with the chassis in order to connect the housing 1 with the chassis. The cover 3 has a soft seal 12 which follows a circumferential groove and thus, the housing 1 can be tightly closed against water and dust.

(8) According to the illustrated embodiment the walls 5 have support elements 7. They serve to mechanically stabilize the walls 5. In the illustrated example the support elements 7 have an advantageous triangular shape. Through the presence of the support elements 7, a very small wall thickness can be achieved without impairing the mechanical stability of the housing 1. Because of this, the wall thickness may only be a few millimeters, for example in the range from 1 mm to 4 mm. Through the smaller wall thickness, the total weight of the housing 1 can advantageously be further reduced.

(9) As illustrated in FIGS. 1 and 2, the walls 5 have different types of openings 8. The openings 8 serve the purpose of connecting the high voltage components contained in the housing 1 or to guide the lines into the housing. The electrical lines, as well as the housing 1 itself, are screened electromagnetically. The connection between the housing 1 and the screen for the lines must be configured so that the total screening should not be interrupted. For example, injected molded metal parts or injection molded flanged bushings can be placed or inserted in the openings 8 into which the lines are screwed so that the screened lines are in contact with the metallic parts. Also, cable shoes which are equipped with self-cutting screws or threads fastened on the housing 1, is possible. Furthermore, the screen for the lines can be soldered or glued on to the housing 1.

(10) Each of the ends of the connecting cable are connected to a mounted threaded box 10 or 11 each in the lower part 2 and the cover 3 for effecting contact between the two parts 2 and 3 of the housing 1. In addition, the housing 1 has in its bottom 4 at least a further collared sleeve or threaded box 9 to fasten the housing 1 on the motor vehicle part and for contact with the chassis, for example, by means of a screw.

(11) A thermoplastic material is used for the housing 1. Suitable thermoplastic material is for example, polyamide, polypropylene or acrylnitril-butudene-styrene (ABS). The metallic particles are, for example, composed of high grade steel, copper or tin. These metals have a relatively high conductivity. They are present in the form of fibers.
