Definitions
- the invention relates to a segmented electrical feedthrough for electrically contacting a heating conductor through a housing, with a heating conductor and an insulating section, the insulating section having an electrical conductor, an insulating means and an outer sleeve, the electrical conductor and the insulating means being arranged within the outer sleeve and the electrical conductor is electrically insulated from the outer sleeve by the insulation means, the heating conductor being connected to the electrical conductor at a predeterminable angle.
- heating catalysts which have a metallic structure connected to a voltage source or have a metallic-coated ceramic structure, which can be heated using the ohmic resistance.
- an electrical conductor must be introduced at least at one point through the housing of the exhaust gas line or a catalytic converter arranged in the exhaust gas line. It must be ensured that the feedthrough is gas-tight, that there is electrical insulation between the housing and the electrical conductor and that sufficient durability is guaranteed.
- the electrical conductor is regularly formed from a solid solid material, such as a metallic bolt.
- a particular disadvantage of the methods known in the prior art for producing an electrical feedthrough is that the compressed rod material used is very expensive because it has a multi-layer structure.
- the machining to free up the electrical conductor and to cut the electrical feedthrough to length a significant proportion of approximately two thirds of the bar material is destroyed by machining and is therefore wasted. The manufacturing process is therefore particularly complex and cost-intensive.
- segmented electrical feedthrough is solved by a segmented electrical feedthrough with the features of claim 1.
- An exemplary embodiment of the invention relates to a segmented electrical feedthrough for electrically contacting a heating conductor through a housing, with a heating conductor and an insulating section, the insulating section having an electrical conductor, an insulating means and an outer sleeve, the electrical conductor and the insulating means being inside the outer sleeve are arranged and the electrical conductor is electrically insulated from the outer sleeve by the insulation means, the heating conductor being connected to the electrical conductor at a predeterminable angle, the heating conductor and the insulation section being formed from two different elements, which are permanently connected to one another by means of a joining process , wherein the heating conductor has a recess into which the electrical conductor of the insulation section can be inserted.
- the electrical feedthrough serves to guide an electrical conductor through a housing of an exhaust pipe or a catalytic converter.
- the bushing must be able to withstand the temperatures that occur and be gas-tight so that no exhaust gas can escape.
- the electrical conductor should be electrically insulated from the housing so that a short circuit cannot occur.
- the electrical conductor is electrically connected to the heating conductor of the segmented electrical feedthrough.
- the electrical conductor and the heating conductor which are preferably formed by metallic bolts, are connected to one another at a predeterminable angle. This means in particular that the electrical conductor and the heating conductor are not connected to one another at the front, but rather the electrical conductor is preferably connected to a lateral outer surface of the heating conductor. With such an angled design, particularly space-saving designs can be created, which are particularly advantageous in the often very limited installation space.
- the heating conductor preferably has a recess, for example a hole, into which the electrical conductor can be inserted and permanently connected to the heating conductor.
- the recess on the heating conductor can, for example, form a press fit with the electrical conductor.
- the recess can also taper conically, for example, so that as the insertion depth increases, the force generated by the insertion and acting in the radial direction on the electrical conductor is increased.
- a preferred exemplary embodiment is characterized in that the recess tapers conically from the opening to the end face of the bore. This is advantageous in order to achieve a certain clamping effect between the electrical conductor and the heating conductor by plugging it in and thus create a stronger connection.
- the central axis of the heating conductor is arranged at an angle of 60 degrees to 120 degrees, particularly preferably approximately 90 degrees, to the central axis of the electrical conductor.
- a connection at an angle of 90 degrees to one another is advantageous in order to create the most compact design possible.
- the central axis of the hole forming the recess can also be tilted by the corresponding angle in order to ensure a precisely fitting connection at the desired angle.
- the insulation section is designed in several parts, with the electrical conductor in particular being designed in two parts, at least in two parts.
- the insulation section can preferably be designed in several parts. This makes it easier to assemble the electrical feedthrough.
- the part of the insulation section that acts as a contact to the heating conductor, in particular of the electrical conductor in the insulation section, is designed separately from the part of the electrical conductor arranged between the insulation means.
- both parts can, if necessary, be aligned with one another during production with the help of an auxiliary tool and, for example, be fixed to one another at certain points by welded connections. In a subsequent soldering process, both parts can then be connected to one another over the entire surface.
- one of the two parts preferably has a solder reservoir which is sufficiently dimensioned to accommodate the required amount of solder.
- the solder reservoir can be formed, for example, by a hole in the electrical conductor.
- the parts of the electrical conductor can be inserted into one another and can be permanently connected to one another using a joining process. By plugging them into one another, the two parts can be positioned in a simple manner relative to one another.
- a solder reservoir can also be provided on one of the parts in order to create a durable connection using a soldering process.
- An exemplary embodiment of the invention relates to a method for producing a segmented electrical feedthrough, wherein the two parts of the electrical conductor are fixed to one another by means of a welding process, wherein the two parts of the electrical conductor and the electrical conductor itself are connected to the heating conductor using a downstream soldering process .
- the electrical feedthrough is easy to produce and can be used advantageously, particularly in confined spaces.
- Fig. 1 shows a segmented electrical feedthrough, wherein the electrical conductor is formed in one piece and can be connected to the heating conductor at an angle of, for example, 90 degrees, and
- Fig. 2 shows a segmented electrical feedthrough, the electrical conductor being designed in several parts and being connectable to the heating conductor at a predeterminable angle.
- Figure 1 shows a segmented electrical feedthrough 1, wherein the feedthrough 1 has a heating conductor 2 and an insulating section 3.
- the heating conductor 2 is designed as a metallic bolt and has a recess 4 running in the radial direction of the heating conductor 2.
- the recess 4 can be created, for example, by a hole.
- a solder reservoir 5 is provided in the bottom of the recess 4, which can hold a defined amount of solder which is used to solder the heating conductor 2 to the electrical conductor 6 of the insulation section 3.
- the heating conductor 2 is shown separately from the insulation section 3.
- the insulation section 3 has a central electrical conductor 6, which is coaxially enclosed by an insulation medium 7, for example an oxide ceramic.
- the insulation means 7 is followed by an outer sleeve 8, which is preferably metallic and can be used to connect the bushing 1 to an external housing.
- the electrical conductor 6 is inserted into the recess 4 and thus a connection between the insulation section 3 and the heating conductor 2 has been created.
- the insulation section 3 is arranged at an angle of 90 degrees to the central axis of the heating conductor 2.
- Figure 2 shows a similar electrical feedthrough 10, whereby, in contrast to Figure 1, the electrical conductor 11 is designed in two parts.
- the electrical conductor 11 has a plug connection 12, with a solder reservoir being provided in the recess of the plug connection 12.
- connection of the lower part of the electrical conductor 11 to the heating conductor 2 takes place as in the exemplary embodiment in FIG.
- FIGS. 1 to 2 in particular do not have a restrictive character and serve to illustrate the idea of the invention.
