Definitions
- the invention is based on a cable bushing in an electrical device.
- a cable bushing is known from DE 40 32 280 AI in an application for an ignition coil.
- an ignition coil For the functionality of an ignition coil, it is essential that the insulation conditions in the ignition coil are not impaired by penetrating moisture. There is a risk of moisture penetrating into the ignition coil, particularly at the entry points of the ignition cable into the ignition coil, which is filled with a hardened, brittle cast resin, since the cast resin and the ignition cable only make a poor connection due to their material properties. Mechanical stress of the ignition cable, in particular due to bending and tensile forces on the movable part of the ignition cable protruding from the casting resin, can lead to detachment of the embedded part of the ignition cable from the casting resin. Moisture can get into the ignition coil along the resulting gap in the casting resin and lead to high voltage losses.
- the ignition cable is covered with a shrink tube before and after it emerges from the casting resin, passed through an opening in a holding element protruding from the casting resin, sealed with an adhesive at the transition point between the shrink tube and holding part, and at the exit point on Holding part covered with an additional molded shrink part.
- This type of cable entry in an electrical device is disadvantageously complex in terms of production technology and large in size.
- the cable bushing according to the invention with the characterizing features of claim 1 has the advantage that the aforementioned shortcomings are avoided.
- the cable bushing has a holding element in which a cable is non-positively fixed in a passage opening.
- a sealing compound formed by a tough-elastic sealing compound, surrounds the passage opening and a section of the cable emerging therefrom, the axial extent of the section being less than the diameter of the cable.
- the functionality is achieved in particular in that the cable at the outlet from the holding element, corresponding to the beginning of the section of the cable, is rigidly coupled to the holding element and the mobility of the cable at the end of the section, when leaving the sealing compound, as far as limited is that it is no longer possible to detach the cable from the resilient, viscoplastic sealing compound.
- FIG. 1 shows a side view of the cable feedthrough in an ignition device with an ignition coil and a device housing
- FIG. 2 shows a holding part of the ignition coil in a front view.
- the cable bushing according to the invention in an ignition device with an ignition cable for ignition elements is intended for use in gas discharge lamps which can be used in headlight systems in motor vehicles. So the Ignition device in a manner not shown, a plurality of ignition coils and at least one choke, which are connected to electronic switching components mounted on a printed circuit board.
- the ignition device is supplied with voltage via a separate control device and, via two ignition cables, one of which carries high voltage and the other represents the ground connection, represents the power supply for the connected gas discharge lamp.
- the ignition device according to FIGS. 1 and 2 has, in a plastic coil housing 11, one of a plurality of ignition coils 14 embedded in casting resin and containing a primary winding 12 and a secondary winding 13.
- a plastic coil housing 11 On one side wall 16 of the coil housing 11, an upper part 17 of a two-part holding element 18 is integrally attached to it as a projection.
- the upper part 17 has two hollow cylindrical half-shells 19 lying next to one another, which are used to hold one cable 20 each.
- the cable 20 is designed as a round cable and is provided with an insulating sleeve 22 made of silicone and enclosing a wire 21.
- the wire 21 is connected to a winding end of the secondary winding 13 via a contact part 23 fastened to the coil housing 11 and designed as a sheet metal angle.
- a lower part 24 With the upper part 17 of the holding element 18 is a lower part 24, which is in one piece as a plastic molded part on a box-shaped Connection body 25 is attached, connected by locking elements.
- the connecting body 25, which is connected to the coil housing 11 via the lower part 24, contains two metallic contact elements 26, which are electrically connected to one winding end of the primary winding 13 of the ignition coil 14.
- the lower part 24 contains, analogously to the upper part 17, two identically designed half-shells 19 which, however, are arranged in the opposite direction to those of the upper part 17 and which, after the two parts 17, 24 have been joined together, form internal passage openings 27 with circular cross-sectional areas ⁇ zen.
- the passage openings 27 each have an inner diameter that is smaller than the outer diameter of the cable 20, the difference in size being in the region of the deformability of the insulating sleeve 22 with annular pressure.
- the passage openings 27 can also have other cross-sectional areas, for example that of a lens, if the half-shells 19 are each formed as an arc of a segment of a circle.
- the coil housing 11 with the cables 20 clamped in the holding element 18 and further parts (not shown) are inserted in a pot-shaped device housing 28 in accordance with FIG. 1.
- This is poured out to form a sealing body for the entry of the ignition cable 20 into the ignition device with a sealing compound 29 which is thin in the initial state and, after a partial hardening in the functional state, is viscous-elastic in such a way that the sealing compound mirror as an end face 31 of the sealing compound 29 has one each from the passage openings 27 emerging part of the cable 20, the following is designated as section 32 and its axial extent is less than the diameter of the cable 20.
