Abstract

The invention relates to a connection system comprising an external cable guide for electrically connecting at least two components (4, 5) that are arranged at a distance from each other on a motor subassembly (1), the positions of said components being fixed in relation to the housing parts (2, 3) of the motor subassembly (1). Said connection system also comprises at least one electric cable (6) connecting the components (4, 5) that are arranged on the motor subassembly (1) and a support element (7) on the outer side of the housing (2, 3) of the motor subassembly (1) that defines the geometric path of the electric cable (6).

Claims

1. A connection system comprising an external cable guide for electrically connecting at least two components (4, 5) which are arranged at a distance from one another on a motor assembly (1) and whose positions in relation to two housing parts (2, 3) of the motor assembly (1) are fixed, comprising at least one electrical line (6), which connects the components (4, 5) which are arranged on the motor assembly (1), and a supporting element (7) on the outside of at least one of the housing parts (2, 3) of the motor assembly (1), which supporting element determines the geometric profile of the electrical line (6), the supporting element (7) being releasably secured to the motor assembly (1) by a plurality of connecting elements (16) engaging at least one of the housing parts (2, 3).

2. The connection system as claimed in claim 1, characterized in that the motor assembly (1) is a motor assembly of a wiper drive of a vehicle, and at least one of the components, whose positions in relation to the housing parts (2, 3) of the motor assembly are fixed, is a contact holder (13) with control contacts (12) for determining the position of at least one gear mechanism element.

3. The connection system as claimed in claim 1, characterized in that the supporting element (7) is a plastic channel (7′

) which is connected to at least one housing part (2) of the motor assembly (1).

4. The connection system as claimed in claim 3, characterized in that the plastic channel (7′

) contains at least one cable which is inserted in the plastic channel (7′

) or a conductive strip which is inserted in the plastic channel (7′

) as an electrical line (6).

5. The connection system as claimed in claim 3, characterized in that the plastic channel (7′

) contains at least one conductive strip which is injection-molded in the plastic channel (7′

) or a cable which is injection-molded in the plastic channel (7′

) as an electrical line (6).

6. The connection system as claimed in claim 1, characterized in that the supporting element (7) is connected firmly to the housing (15) of a plug or plugging slot by means of which connection is made with the motor assembly (1).

7. The connection system as claimed in claim 1, characterized in that the supporting element (7) is connected to a plugging adapter (17) which is coupled to a motor housing (3) of the housing parts (2, 3) and is configured to receive a plug, by means of which connection is made with the motor assembly (1).

8. The connection system as claimed in claim 1, characterized in that the supporting element (7) is connected firmly to a contact holder (13) with control contacts (12) for determining the position of at least one gear mechanism element.

9. The connection system as claimed in claim 1, characterized in that the plurality of connecting elements (16) extend from the supporting element (7).

10. A motor assembly (1) comprising housing parts (2, 3), at least two components (4, 5) which are arranged at a distance from one another, the positions of the components in relation to the housing parts (2, 3) being fixed, and a connection system including an external cable guide for electrically connecting the components (4, 5), at least one electrical line (6) which connects the components (4, 5), and a supporting element (7) on the outside of at least one of the housing parts (2, 3) of the motor assembly (1), which supporting element determines the geometric profile of the electrical line (6), the supporting element (7) being releasably secured to the motor assembly (1) by a plurality of connecting elements (16) engaging at least one of the housing parts (2, 3).

11. A motor assembly (1) as claimed in claim 10, characterized in that the motor assembly (1) is a motor assembly of a wiper drive of a vehicle, and at least one of the components, whose positions in relation to the housing parts (2, 3) of the motor assembly are fixed, is a contact holder (13) with control contacts (12) for determining the position of at least one gear mechanism element.

12. A motor assembly (1) as claimed in claim 10, characterized in that the supporting element (7) is a plastic channel (7′

) which is connected to at least one housing part (2) of the motor assembly (1).

13. A motor assembly (1) as claimed in claim 12, characterized in that the plastic channel (7′

) contains at least one cable which is inserted in the plastic channel (7′
