Definitions
- the invention relates to a method for connection a rod-shaped heating element with a tubular support element and glow plugs with such a rod-shaped Heating element in a tubular glow plug body.
- Rod-shaped heating elements which are tubular Carrier elements are stored; one of the most famous Examples are glow plugs, in which a rod-shaped Glow plug stored in a tubular glow plug body is.
- the glow plug is pressed into the glow plug body; only materials can be used here the sufficient ductility and dimensional stability for have such a pressing process.
- scoring can occur when pressing in, the leak between glow plug and glow plug body to lead.
- the invention has for its object methods for Connecting a rod-shaped heating element with a tubular one
- this method is not intended to be of a particular Component length to avoid kinking Be dependent on the component; in particular, ceramic should also rod-shaped heating elements with metallic support elements can be easily connected, the described Streaking should not occur.
- Forming is an essential feature of the invention of the rod-shaped heating element with a carrier ring by means of magnetic forming technology, this technology for example under the term “MagnetoPuls” from Magnet-Physik Dr. Steingroever GmbH, Cologne, Germany becomes.
- Figure 1 schematically shows a glow plug in side view 1 made of electrically conductive ceramic, on the by means of Magnetic forming a support ring 2 is formed, the Material of the carrier ring 2 electrically conductive and by means of Magnetic forming technology is deformable.
- a connecting pole 5 leads as a positive pole into the glow plug 1 in.
- the arrangement of Figure 1 is in one Glow plug body 3 introduced, this being done in this way can that the press-in or insertion force for insertion the arrangement in the glow plug body 3 on the carrier ring 2 is brought into effect, so that the risk of buckling of glow plug 1 with connection pin 5 does not occur at all can, and also quite thin glow plugs 1, and as in the present case, made of material that is easier to damage, how ceramics can be used.
- the glow plug body serves as a single pole 3 as ground or negative pole.
- Glow plug body 3 is preferred on the carrier ring 2 molded using magnetic forming technology, as in described a little later in Figures 4 and 5 becomes.
- FIG. 3 shows the arrangement of glow plug 1, carrier ring 4 and connection pole 5 of another glow plug shape according to the invention.
- a glow plug 1 made of ceramic used into which an internal pole 5 projects on the connection side, and extended on the connection side with a contact sleeve 6 is.
- the carrier ring 4 is indeed again from a material that uses magnetic forming technology is deformable; its surfaces, at least the ones facing outwards, however, are insulating, for example coated with an insulating ceramic layer, educated. Otherwise, the carrier ring 4 by means of magnetic forming technology applied to the glow plug 1; in the same The contact sleeve 6 is around the glow plug end region on the connection side formed.
- the glow plug 1 can also consist of steel, and then using an applied ceramic layer is electrically insulated.
- the contact sleeve 6 has the same outer diameter how the carrier ring 4 has, is its outward-facing Surface also formed isolated, for example provided with an insulating ceramic coating.
- the outer diameter of the carrier ring is preferred 4 larger than the outer diameter of the contact sleeve 6, so that the body 3 does not contact the sleeve 6.
- the carrier ring 4 preferably consists of a copper or Aluminum alloy, the ring 4 with an anodized layer or a layer of lacquer is insulated.
- FIG. 3 The arrangement according to FIG. 3 is broken down into one according to FIG Introduced glow plug body 3; this is what happens here again preferably by means of magnetic forming technology, the Arrangement according to Figure 3 in the glow plug body 3 in the intended Position is positioned; in the area of the carrier ring 4 a transmission ring 7 is arranged around the body 3, via which the magnetic forming takes place.
- the glow plug body 3 after removal the transmission ring 7 a cylindrical constriction 8, which over the inner carrier ring 4th with fixed connection of the arrangement of Figure 3 in the glow plug body 3 is formed.
- the contact sleeve 6, which protruding from the glow plug body 3 is as a minus contact connection trained while the glow plug housing 3 floating is.
- contact sleeve 6 and carrier and transmission ring 2, 4 or 7 made of copper, aluminum or light metal alloys.
