  • the invention has for its object to provide an immersion device of the type mentioned, which by means of its holding device in a simple manner fixed in relation to the pool edge of the process liquid
  • connection head of the immersion device Due to the straight holding recesses, the connection head of the immersion device is held in such a way that the immersion tube is also able to flow within the process liquid, even with strong currents
  • the dip tube 35 can not perform any unwanted movements that lead to contact with the edge of the pool. This in turn allows the dip tube to be in closer proximity to the Pool edge can be arranged without having to fear such unwanted contacts. This in turn creates a larger usable space with the same pool size.
  • the mounting of the immersion device is further improved. This takes place not only in two opposite side areas of the connection head, but also on a third side lying between them.
  • the immersion device Due to the characterizing feature of claim 3, a twist-proof mounting of the immersion device is possible, whereby the positional stability of the immersion device within the mounting is further improved.

  • the space available for accommodating electrical parts is enlarged.
  • a particularly secure mounting of the immersion device is guaranteed by the characterizing feature of claim 5; however, it is still possible to insert the immersion device smoothly into the holder. Due to the characterizing features of claims 6 and / or 7, a plurality of holding devices can be attached next to one another in a confined space on the edge of the pool. Due to the characterizing feature of claim 8, it is possible in a simple manner to side by side connect the relevant holding devices inseparably by mutual welding *. The Faskanten from each other thereby tangential side walls form with one another namely a V-shaped groove that simply execute by a weld bead 'are üllbar.
  • the holding brackets lie in the holding position with a prestress directed against the groove base in the recesses of the connection head. This in turn improves the strength of the bracket.
  • the resulting preload is also advantageous with regard to the high ambient temperature in electroplating baths, the holding device also being known to be made of plastic, as is known.
  • this makes it possible to remove and reinsert an immersion device from a holding crossbar without mutual hindrance, even if the holding devices are located next to one another and are possibly firmly connected to one another, without the associated, on the holding bracket of a holding crossbar exerted spreading movements are hindered by a bracket of an adjacent crossbar.
  • the characteristic feature of claim 10 reinforces the transition area between the supporting body and the holding bracket, as a result of which higher weights can be absorbed by the holding crossmember without the risk of breakage.
  • the immersion device can be optionally connected to the holding device in different height positions. This is particularly advantageous in view of the fact that the clearance available above the basin filled with the process liquid is often limited in electroplating systems. One will therefore always endeavor to use the immersion device with the To connect the holding device so that its connecting head protrudes as far as possible beyond the edge of the pool. With this feature of the invention, the fixation of the immersion device at the edge of the pool can be easily adapted to the height of the liquid level in the pool.
  • the distance of the immersion device from the pool edge can be adapted to the particular circumstances in operation. Due to the characterizing feature of claim 13, it is possible to fix the position of the connection cable outside the connection head so that no undesired deflection forces on the part of the connection cable are exerted on the connection head.
  • the retaining brackets can be additionally secured by a pulled-through connecting means.
  • the diving device can also be protected against unauthorized removal by a sealing wire between these holes.
  • the bore in the peripheral wall of the connection head for the connection cable described in the characterizing part of claim 20 also offers additional protection for this.
  • the immersion device can thereby be fixed directly and firmly, for example with a sealing wire, within the holding crossmember.
  • connection head is composed of a cap part and a flange part on the dip tube side. Both parts enclose the connection space for the electrical lines.
  • the snap-on cover offers advantages in the manufacture of the immersion device and in its use. During assembly, all electrical connections can easily be made through the opening at the top and the conductor wires can be laid neatly. After assembly, the terminal compartment is hermetically sealed against the mostly aggressive environment by the snap-on cover.
  • the cover can simply be lifted off again and the desired change made. By eliminating screwing movements when closing the cover, undesired twisting forces on the electrical leads are avoided.
  • additional control parts such as circuits or the like can be added to the inside of the cover if necessary. be accommodated.
  • An increase in the overhang dimension of the immersion device need not be associated with this if, in accordance with the characterizing feature of claim 19, height compensation is possible by selecting a different, higher holding recess for the engagement of the holding traverses.
  • the intermediate rings which can subsequently be inserted between the cap and flange part enable the bathroom heater to be better adapted to the particular operating conditions required. If, for example, a large height adjustment range is desired, this can be achieved by inserting several intermediate rings.
  • the volume of the connection space can also be increased as a result. If, however, the user attaches importance to a low overall height of the connection head, this can be achieved by removing all intermediate rings, deliberately dispensing with the possibility of height adjustment.
  • the characterizing feature of claim 23 prevents the screws arranged in the connection space from coming into contact with aggressive vapors or liquids. By means of the characterizing feature of claim 25, the immersion devices can be subsequently changed in a simple manner and thereby adapted to certain special tasks.
