Definitions
- the invention relates to a connection between a connecting line and a device to be electrically connected therewith, in particular with an electrically heatable catalyst.
- Such catalysts are known per se (DE-44 35 784). They have a metallic housing with an actual catalyst arranged therein, which is exposed to the exhaust gas flow and which is provided with an electrical resistance heater. Outside the housing, an electrical connection line is introduced through an opening, which is formed as a metal sheathed line with at least one of the metal anteln by means of a mineral electrically insulated inner conductor, which is non-positively connected to the electrical resistance heater, the metal sheath through the opening in the metal housing is inserted and is gas-tightly connected to it along the edge of the opening by welding or soldering.
- the invention is therefore based on the object of enabling reliable, long-term stable electrical contacting with at least one repair option (separation of device and connecting line).
- a two-part detachable connection one part of which is arranged on the device and the other part at the end of the metal sheathed line, is plugged into one another in the manner of a plug-socket connection and intimately connected to one another in this state, for example cohesively or by means of a press fit, whereby a secure long-term connection is achieved that is safe, permanent and can also be used at high temperatures.
- the good electrical connection in the case of a cohesive electrical connection is purchased through a more complex exchange of the (original) metal sheathed cable.
- the inner conductor of the metal sheathed line must be separated using a tool and then either a replacement metal sheathed line with a fitting sleeve at one end must be used, which encompasses the outside of one part (socket), in the inner part of which the cut-off inner conductor of the connecting line has remained, or else Fit sleeve on the separated end of the inner conductor of the metal sheathed line and fixed, for example welded.
- a second variant is provided to avoid a separate replacement metal jacket line with the adapter sleeve.
- an original metal sheathed cable that can be replaced as often as required can be used by means of a screw connection, for which purpose a screw-on section with a blind hole for receiving and for electrical connection (welding, soldering or press-fitting) of the inner conductor is provided on the part of the device.
- the easily detachable electrical connection to the device then takes place via the screw connection.
- either the inner conductor can be removed with a tool and then the section can be unscrewed and replaced with a new one - an (original) metal sheathed cable can then be used again, or the metal sheathed cable can be completely unscrewed and used several times.
- a third solution is to thread the inner conductor on its outside.
- the part designed as a connecting bolt on the device must be provided with an external thread adapted to the internal thread, with a different direction of rotation. Both parts are then pulled towards each other when the connecting sleeve is turned by means of a connecting sleeve which has two adapted internal threads with opposite directions of rotation. They are firmly clamped in the sleeve, so that on the one hand there is a well-protected, corrosion-free connection and, on the other hand, problem-free releasability in the event of a repair.
- connection is provided with an outer protective sleeve against dust and / or moisture, which is designed in the manner of a union nut and has an internal thread 98/01653
- one of the parts of the connection connection provided with an external thread can be screwed on.
- This part not only provides good protection, but also strain relief at the same time.
- the protective sleeve can overlap a collar placed on the metal jacket line and fixed there and have at least one sealing edge on the contact surfaces between these parts in order to improve the sealing function.
- the connecting bolt can furthermore have a hollow pin, which is concentric with it and designed as a connecting piece and comes into contact with the collar, thereby further improving the tightness.
- additional sealing edges can be provided on the contact surfaces.
- Figure 1 shows a catalyst with part of a connection connector, in schematic cross section
- Figure 2 shows the electrical connection line with the other part of the connection
- Figure 3 shows the replacement connection line with a fitting as another part of the connection
- Figure 4 shows a second embodiment of the connection, in schematic cross section
- FIG. 5 shows the connection according to FIG. 4, as a schematic exploded view
- Figure 6 shows a third embodiment of a connection
- FIG. 7 shows the connection according to FIG. 6, as a schematic explosive diagram.
- the catalytic converter designated overall by 10 in FIG. 1 has an actual catalytic converter 11 with a multiplicity of channels 12 which run parallel to one another and through which exhaust gas flows.
- individual, heatable foils are provided which have a connecting bar 13, a tab 14 bent at right angles and a connecting bolt 15 fastened thereon. This is provided with a blind hole 16 on its front side.
- a connector 17 is provided concentrically with the connecting bolt 15 and is provided with an external thread 18 at its front end. In the intermediate area, a mechanical and electrically insulating support 19 can be provided for the connecting bolt.
- the connecting line 20 is shown in Figures 2 and 3. It has a flexible inner conductor 21 which is separated from the outer metal jacket 22 by means of electrical insulation, preferably an electrically insulating mineral 23. To seal the Layer 23 may be provided with insulation 24 or an impregnation or a glass closure at the two ends of the metal jacket 22.
- a metal collar 25 with a U-shaped cross section is placed on one end of the connecting line 20 and is soldered or welded to the metal jacket 22.
- the inner conductor is also provided with a notch 26, which acts as a predetermined breaking point and on which the inner conductor can be separated by means of a tool.
- an outer protective sleeve 27 is placed, which is provided with an internal thread 28, de in the manner of a union nut as dust and moisture protection via the connection on the external thread 18 of the socket 17 can be screwed, the protective sleeve 27 via the collar 25 also serves as strain relief for the inner conductor 21.
- the free end 29 of the inner conductor 21 projects to such an extent that it projects into the blind hole 16 of one part of the connection and is welded or soldered there or fixed by means of an interference fit and at the same time can be connected in an electrically conductive manner, after which the protective sleeve 27 of the other Part of the connection can be screwed onto the external thread 18.
- the protective sleeve 27 is unscrewed and the free end 29 of the inner conductor 21 is cut off at the separation point 26 by means of a tool.
- the replacement line shown in FIG. 3, the free end of which is provided with a fitting sleeve 30 on the inner conductor 21, can then be used.
- the adapter sleeve 30 is formed so that the inside of it Grips outside of the connecting bolt 15 and in this state can also be soldered or welded or fixed by means of an interference fit, the adapter sleeve 30 also containing the part of the free end 29 of the inner conductor 21 of the connecting lead 20 which is separated and located in the blind hole 16. In this state, the adapter sleeve 30 is then soldered to the free end of the connecting bolt 15.
- FIGS. 4 and 5 An alternative second embodiment is shown in FIGS. 4 and 5, the same reference numerals denoting the same parts and therefore not being described again.
- a separate screw-on section 40 is provided, which is screwed into an internal thread 41 on the end face of the connecting bolt 15 with an external thread 42 and which contains the blind hole 16 for receiving the free end 29 of the inner conductor 21.
- the first and the second embodiment are the same, with the slight difference that the connection between the section 40 and the connecting bolt 15 is a screw connection.
- both the free end 50 of the connecting bolt 15 and the free end 29 of the inner conductor 21 each have an external thread 52, 53 on their surface 51, which have opposite directions of rotation.
- a connecting sleeve 60 each with an adapted internal thread 61, 62 and a region-wise outer shape 63, is connected to one another.
- the outer shape 63 is used to attack a tool, preferably a wrench.
