Definitions

  • the invention is based on a tubular casing for the electrical insulation of components according to the preamble of claim 1.
  • Such casings are well known. They are used to isolate connections and encapsulate electrical components such as capacitors, relays, coils, thermal circuit breakers and the like. Their dielectric, mechanical and thermal properties are adapted to the respective application. Depending on the required thermal load capacity and the necessary dielectric strength, there are different versions with different dimensions. They preferably consist of a polyester or polyolefin material with or without shrinkage. The thermal resistance can be increased by lining the tubular sheaths with aramid paper. However, this reduces the shrinking capacity of the hose material, insofar as it has this property.
  • the above-described shells are usually already formed into a cap at one end, for example under the action of heat by flat pressing. After the component is inserted, the other is also End of the cap closed accordingly.
  • a hard crescent-shaped surface is formed at both ends, which protrudes outward beyond the tubular body with sharp edges.
  • the object of the invention is therefore to provide an insulating sheath for electrical components in which the risk of injury to adjacent components is reduced to a minimum by such an insulated component.
  • FIG. 3 shows a plan view of a tubular casing 1 which, according to a prior art, is welded at the end by simple flat pressing under, for example, the action of the two end regions 2 and 2a of the casing.
  • the end regions 2 and 2a are deformed in a crescent shape and have sharp-edged corners which also protrude laterally beyond the rest of the casing body.
  • FIG. 1 shows, on the other hand, a tubular casing 1, one end of which is also welded by flat pressing, but the end region 2 of which tapers towards the front in a wedge shape. This is achieved by folding the front casing end in a fold-shaped manner on opposite sides of the end region 2.
  • FIG. 2A shows the casing 1 of FIG. 1 with a view of the end face to be closed before pressing.
  • the envelope 1 is folded in the end region 2 on opposite sides towards the center in such a way that the end region 2 tapers towards the front due to the formation of the folds 3, as can be seen in FIG.
  • the casing end thus prepared is then pressed in a conventional manner using heat or adhesive.
  • FIG. 2B shows the casing 1 closed on one side with a wedge-shaped tapering end region 2 according to FIG. 1.
  • FIG. 4 shows a casing 1 according to FIG. 1, which is equipped with an electrical component 5, the connections 6 of which are led out on one side. With its open end, the cap-shaped casing 1 projects far beyond the component 5 so that the end region 2a is long enough to form folds 4.
  • FIG. 4A shows the FIG. 4 in a view of the end face with the connections 6 led out. As FIG the connections 6 is applied. The folds 4 are fixed by a subsequent shrinking process, the casing material simultaneously laying tightly around the component 5 and the connections 6.
  • FIG. 5 shows an electrical component 10 protected by a sheath 7, the connections 11 of which are led out on opposite sides.
  • the casing 7 is open on both sides for the purpose of fitting with a component 10.
  • the sleeve 7 is longer by the end regions 7a and 7b than the component 10 in order to ensure the formation of folds 8 and 9.
  • FIG. 5A shows FIG. 5 in the view of the end faces with the connections 11 led out. Since the views of both end faces are the same, a double representation is unnecessary.
  • the folds 8 and 9 are formed in the manner shown and described by FIGS. 2A and 2B.
  • the shrinking process which follows the fold formation and to which the sleeve 7 is subjected, is reduced 5A tightly around the component 10 and the connections 8 and 9.
  • the tubular casing material preferably consists of a polyester or polyolefin material with or without shrinking properties.
  • shrinkable tube material for the sheath 1 or 7
  • materials with different shrink rates are available.
  • the shrinking capacity decreases with increasing thermal load capacity of the hose material.
  • non-shrinkable aramid paper the shrinkability continues to decrease.
  • the folding of the sleeve 1 or 7, with the pressing of which a shrinking of the end regions 2 and 2a or 7a and 7b can be connected must take place to a degree which ensures that the sleeve 1 or 7 after the Shrink fit on an electrical component still has a tapered end regions 2 and 2a or 7a and 7b.
  • the folds 3 and 4 or 8 and 9 can be slightly folded be less.
  • the folding in of the casing ends ensures that when an electrical component protected by a casing 1 or 7 is inserted, damage to the insulation of adjacent electrical modules or lines is largely prevented due to the edge-free and wedge-shaped tapering ends of the casing.
  • the area of the folds 3 and 4 or 8 and 9 there is a multiple material thickness, which above all results in an increase in the dielectric values in this area.
