Definitions
- Internal combustion engine having a connecting means for connecting a first to a second section of a wire harness on a cylinder head housing
- the invention relates to an internal combustion engine with a connecting means for connecting a first to a second section of a wire harness on a cylinder head housing according to the preamble of claim 1 and a method for installation.
- the fuel is injected into the combustion chamber by an injector.
- an electronic control unit determines the corresponding one
- the signals are transmitted via a cable harness. Since the injector is located inside the cylinder head housing, the wiring harness must be led through the cylinder head housing. This procedure is critical since the cylinder head housing must be lubricant and fuel-tight to the environment. Due to the motor vibrations, the wiring harness on the bushing is also exposed to mechanical stress.
- EP 0 454 895 B1 shows an implementation for a cable harness on a cylinder head.
- the wiring harness is melted into a gasket, which is arranged between the cylinder head and the hood.
- the wires of the wiring harness are pushed through holes in the seal. The problem here is the possible mechanical damage to the wiring harness due to excessive tightening torques when the hood is attached to the cylinder head.
- DE 197 34 970 A1 shows a central plug which is screwed to the cylinder head housing of the internal combustion engine.
- the wiring harness from the electronic control unit to the injector consists of a first and a second section.
- the first section extends from the electronic control unit to a mating connector.
- the second section of the wiring harness extends inside the cylinder head housing from the central connector to the injector.
- the central plug closes the cylinder head with a seal that is lubricant and fuel-tight.
- the problem with the plug-socket concept is the manufacturing costs of the parts themselves and the complex production of the first section of the cable harness with the mating connector.
- the invention is based on the object of providing a connection means for the cable harness / cylinder head-housing interface which is inexpensive, easy to assemble and leakproof.
- the connecting means comprises a clamp carrier and a hood and both the clamp carrier and the hood have means for self-locking.
- the hood is self-locking via a locking ring or locking lug.
- the self-locking mechanism on the clamping bracket is designed using locking lugs.
- the clamp bracket is fixed in the assembled state on the cylinder head housing by the catches engaging behind the cylinder head housing and sealing to the interior.
- the hood is then attached to the clamp bracket via the locking ring or locking lug. No further steps are required to fasten the clamp bracket and hood. Additional fasteners, such as screws and holes, are also omitted.
- the locking ring in the hood has the advantage that the hood, with a corrugated tube hose attached to it, allows any angular position on the clamping bracket.
- the lanyard is designed for the predicted service life of a large diesel engine, i. H. the lanyard is vibration stable for this period.
- the clamp support have clamps and covers, each clamp consisting of a compression spring and a busbar.
- the second section of the cable harness is permanently connected to the busbar, for example by soldering or crimping.
- the second section of the cable harness is cast in the clamp carrier. This guarantees tightness and vibration stability.
- the wires of the first section of the wiring harness will be held between the compression spring and the busbar due to the spring force.
- the advantage of this arrangement is that there is no mating connector at the end of the first section of the cable harness.
- a screwdriver is all that is required to attach the first section of the cable harness to the terminal support.
- the clamping effect of the compression spring guarantees a constant clamping effect even under
- FIG. 1 is an overview picture
- Figure 2 shows a connecting means, first embodiment (single part representation);
- Figure 3 shows a connecting means, first embodiment (assembly view);
- Figure 4 shows a connecting means, second embodiment (single part representation);
- FIG. 5 shows a connecting means, second embodiment (assembly representation);
- Figure 6 shows a procedure for installation.
- FIG. 1 the lower half of a cylinder head housing 2 is shown on a crankcase 1 of the internal combustion engine.
- An injector 3 and a valve train 24 are arranged in the cylinder head housing 2.
- the injector 3 is connected via a high-pressure line 22 • pressurized fuel supplied, for example from a high-pressure accumulator of a common rail system.
- the switching state of the injector 3 is determined by an electronic control unit 6 (EDC).
- EDC electronice control unit
- the signals are transmitted via a cable harness. This consists of a first section 4 and a second section 5.
- the first section 4 of the wiring harness extends from the electronic control unit 6 to the connecting means 7.
- the connecting means 7 represents the interface between the wiring harness and the cylinder head housing.
- the second section 5 of the wiring harness extends in the interior of the cylinder head housing 2 from the connecting means 7 to the injector 3.
- the end of the second section 5 facing away from the connecting means 7 is connected to the injector 3 via a plug contact 23.
- the connecting means 7 is shown before final assembly.
- a clamping bracket 8 is already in the fixed state on the cylinder head housing 2.
- the hood 9 and the first section 4 of the wiring harness are shown with stripped wires.
- FIGS. 2 and 3 shows the connecting means 7 in a first embodiment as an individual part representation and FIG. 3 as an assembly representation.
- the connecting means 7 is composed of the following components: a hood 9, clamps 16, cover 19, clamp carrier 8 and a corrugated tube hose 21.
- the corrugated tube hose 21 protects the wires of the wiring harness from mechanical damage due to the vibrations.
- the hood 9 consists of the I-shaped hood parts 9A and 9B. These are hingedly connected to each other via a plastic hinge. Each hood part carries a portion of a locking ring 11, reference numerals 1A and 11B in the interior. This locking ring 11 engages in a groove 12 in the clamping support 8, see FIG. 3 for this purpose 9 rotate 360 degrees on the clamping body 8. This achieves the advantage that the hood 9 with the corrugated tube hose 21 attached to it can assume any angular position after the attachment of the connecting means 7 to the cylinder head.
- Two clamps 16 are arranged in corresponding cutouts in the clamp carrier 8. Each clamp 16 comprises a compression spring 17 and a busbar 18.
- the clamps 16 are mounted in a corresponding contour on the upper side of the clamp carrier 8 and the cover 19.
- the cover is shown in FIG 19 executed in two parts, reference numerals 19A and 19B.
- a plurality of webs 26 with locking lugs 15 are arranged in one piece on a base body 25 of the clamping carrier 8.
- the clamping bracket 8 engages behind the wall of the cylinder head housing 2 via the locking lugs 15.
- the locking carrier 8 is thus self-locked via the locking lugs 15.
- a groove 20 for receiving an O-ring is provided to seal the clamping carrier 8 with respect to the cylinder head housing 2.
- the second section 5 of the wiring harness is permanently connected to the busbar 18, for example by soldering or crimping.
- the second section 5 of the wire harness is cast in the clamp carrier 8. This guarantees tightness and vibration stability.
- FIGS. 4 and 5 shows the connecting means 7 in a second embodiment as an individual part representation and FIG. 5 as an assembly representation.
- the first and second versions of the connecting means 7 differ in the design of the hood and an additional eyelet on the clamping bracket 8 (FIG. 4).
- the connecting means 7 is composed of the following components: a hood 10, cover 19, clamping bracket 8 and corrugated tube hose 21. Two webs 27 with locking lugs 13 are arranged on the hood 10.
- the hood 10 is fixed in eyelets 14 of the clamping bracket 8 after assembly via these locking lugs 13.
- the further functionality of the clamp carrier 8, the clamp 16 and the cover 19 correspond to the explanations in FIGS. 2 and 3.
- FIG. 6 shows a process sequence for installing the connecting means 7 in the cylinder head housing 2 of an internal combustion engine.
- a step S1 the clamping bracket 8 with the second section 5 of the wire harness is inserted into the cylinder head housing 2, the latching lugs 15 engaging behind the housing wall and the
