Electrical device comprising a connecting cable and method for producing said device
View Patent ↗The invention relates to an electrical device ( 1 ), especially for a motor vehicle. Said device comprises an electrical component ( 2 ) and a connecting cable ( 5 ) which is connected to the component ( 2 ) and is surrounded by a sheathing ( 8 ), the end ( 9 ) of said sheathing being at a distance from the component ( 2 ). The sheath end ( 9 ) and the respectively connected regions ( 13, 14 ) of the sheathing ( 8 ) and the connecting cable ( 5 ) comprise a sealing coating ( 16 ). The aim of the invention is to improve the sealing and to increase the durability thereof. To this end, another section ( 10 ) of the sheathing ( 8 ), embodied in a sleeve-shaped manner, is arranged between the sheath end ( 9 ) and the component ( 2 ), and the coating ( 16 ) extends over a sleeve end ( 11 ) facing the sheath end ( 9 ) and over the region ( 17 ) of the sleeve-shaped section ( 10 ) of the sheathing ( 8 ) connected thereto. The invention also relates to a method for producing one such device.
1. An electrical apparatus for a motor vehicle, comprising:
an electrical component;
a connecting cable connected to said electrical component;
a sheath having first and second sheath sections arranged on said connecting cable, said first sheath section ending at a sheath end arranged at a distance from said electrical component, said second sheath section comprising a sleeve arranged on said connecting cable between said sheath end of said first sheath section and said electrical component such that a section of said connecting cable between said first and second sheath sections and another section of said connecting cable between said second sheath section and said electrical component is not covered by said sheath; and
a sealing covering extending from the first sheath section over a sleeve end of said second sheath section and over a portion of said second sheath section adjacent to said sleeve end such that said sealing covering covers said section of said connecting cable between said first and second sheath sections, and said sealing covering extends over said second sheath section and at least a portion of said section of said connecting cable between said second sheath section and said electrical component.
2. The electrical apparatus of claim 1 , wherein said sealing covering is a shrink sleeve.
3. The electrical apparatus of claim 1 , further comprising an adhesive arranged between said sealing covering and said sheath, and between said sealing covering and said connecting cable.
4. The electrical apparatus of claim 1 , wherein said electrical component has an electrical plug element with a plug connection.
5. The electrical apparatus of claim 1 , wherein said connecting cable is a multiconductor cable including at least first and second conductors.
6. The electrical apparatus of claim 1 , further comprising a sensor, wherein an end of said connecting cable facing away from said electrical component is connected to said sensor.
7. A method for producing of an electrical apparatus as claimed in one of the preceding claims, said method comprising the steps of:
cutting a sheath circumferentially forming first and second sheath sections, the sheath being arranged on a connecting cable connected to an electrical component, the second sheath section being in the form of a sleeve;
pulling the second sheath section free toward the electrical component so that the second sheath section is arranged at a distance from an end area of the first sheath section and facing the electrical component, whereby a section of the connecting cable between the first and second sheath sections is not covered by the sheath;
drawing a shrink sleeve over the sheath so that the shrink sleeve extends from the first sheath section to the second sheath section and covers the section of the connecting cable, between the first and second sheath sections, and so that the shrink sleeve is drawn over the second sheath sections and over at least a portion of the section of the connecting cable between the second sheath section and the electrical component; and
shrinking the shrink sleeve under the influence of heat onto the connecting cable and the sheath, thereby forming a sealing covering.
