Definitions

  • the invention concerns a laminated connector as used for connections carrying high currents, e.g., for connecting a generator circuit breaker with adjoining sections of an insulated phase bus duct.
  • Laminated connectors consisting essentially of copper or some other metal or alloy like aluminium or stainless steel are well known in the art, see, e.g., EP 0 695 012 Al, EP 0 959 546 Al and JP 2000-316 224 A.
  • a laminated connector according to the generic part of claim 1 is known where, at opposite end portions, the copper stripes are connected by press-welding to form solid contact blocks.
  • Each contact block is covered completely by a silver layer for improving contact with adjoining sections of a conductor.
  • the silver layer is applied after the welding step by electro-plating. Unless this step is carried out with the greatest care, however, fluids used therein can penetrate between the copper stripes where their residues may cause corrosion during storage and, as a consequence, quick deterioration of the connector under the thermal and mechanical strains occurring during use. Summary of the invention
  • the plating step is also simplified as the individual stripes are easier to handle than the connector as a whole. Silver can be applied more selectively, e.g., only to the exposed surfaces of the uppermost and lowermost stripes.
  • That the bonding step is simple and takes very little time, allowing faster and cheaper production, is another advantage of the connector according to the invention.
  • Fig. 1 shows a top view of a laminated connector according to the invention
  • Fig. 2 shows a side view of the laminated connector of Fig. 1,
  • Fig. 3 shows an enlarged top view of an end portion of the laminated connector of Fig. 1,
  • Fig. 4 shows an enlarged cross section along IV-IV in Fig. 3
  • Fig. 5 shows an enlarged cross section along V-V in Fig. 3.
  • the laminated connector essentially consists of a stack 1 of congruent rectangular stripes, preferably of copper or a copper alloy although other materials of high electrical conductivity, in particular, metals or alloys like aluminium or stainless steel, are also possible.
  • the stripes are unconnected at a wavy middle section of the stack 1 which exhibits two lateral minor crests 2a, b and at the centre an opposite major crest 3, the waviness improving the flexibility of the connector, they are rigidly connected at end portions, forming contact blocks 4a, b there.
  • Each of the contact blocks 4a, b is provided with two through holes 5 which can each take up a bolt for connection with adjoining rigid conductors, e.g., sections of an insulated phase bus duct connecting a generator to a generator circuit breaker.
  • the stripes 6 (Figs. 4, 5) have congruent patterns of rectangular bonding deformations 7, with superposed bonding deformations 7 in the stack 1 of stripes 6 being virtually equal, each with a displaced plane bottom portion 8 separated form the surrounding parts of the stripe 6 by straight longitudinal boundaries 9 where the stripe 6 is disrupted, the bottom portion 8 being entirely separated from the adjacent part of the same, and complementary straight perpendicular boundaries 10 where the deformation is more gradual such that the stripe 6 is continuous, the bottom portion 8 being connected to the adjacent portion of the same.
  • the bottom portion 8 is in each case, in a direction perpendicular to a plane of the stripe 6, displaced with respect to the surrounding portion of the same by a distance which is at least as large as the thickness of the stripe 6, preferably at least twice as large .
  • the bonding deformations 7 are, two at each side, arranged close to the lateral edges of the contact blocks 4a, b.
  • the uppermost stripe and the lowermost stripe each carry, on the exposed upper and lower surfaces, respectively, of their end portions a silver coating 11 providing a contact surface 12 which improves the electrical contact with adjoining conductors .
  • the stack 1 typically has a length of between 100mm and 250mm, a breadth of between 20mm and 50mm and a thickness of between 3mm and 15mm.
  • the stripes 6 are all of the same shape and dimension and may have a thickness of between 0.1mm and 0.5mm, e.g., 0.2mm each.
  • the bonding deformations 7 are, e.g., between 5mm and 10mm long with their breadth between lmm and 3mm.
  • the displacement distance i.e., the distance of the position of the bottom portion 8 with respect to the surrounding portion of the stripe 6 perpendicular to the plane defined by the latter is typically between 0.5mm and 2mm.
  • the distance of the crests 2a, b, 3 from a middle plane defined by the contact blocks 4a, b is between 5mm and 30mm.
  • the thickness of the silver coating is typically about 5 ⁇ m.
  • the laminated connector is produced from the stripes 6 in that silver coatings are applied to one surface of a stripe which is to become the uppermost stripe at its end portions and in the same way to one surface of a stripe which is to become the lowermost stripe to later form contact surfaces.
  • the stack 1 is formed with the silver-coated surface portions of the uppermost stripe and the lowermost stripe facing upwards and downwards, respectively.
  • the contact blocks 4a, b are then punch-formed, i.e., the end portions of the stack 1 are bonded in that they are pressed each by a stamp exhibiting a plane surface with isolated protrusions for forming the bonding deformations against a base with a parallel plane surface provided with complementary holes or recesses. In this way the congruent oblong bonding deformations 7 are produced in every one of the stripes 6.
  • the end portions of the stripes 6 are held tightly together by the bonding deformations 7, forming the rigid contact blocks 4a, b.

Abstract

La présente invention concerne des parties d'extrémité d'une pile (1) de bandes (6) affichant une épaisseur comprise entre 0,1 et 0,5 mm et composées essentiellement de cuivre, qui sont liées par poinçonnage, de manière à former des blocs de contact rigides (4a) avec les surfaces supérieure et inférieure, chacune étant recouverte d'un revêtement d'argent (11) appliqué avant la liaison pour fournir des surfaces de contact (12). Lors du poinçonnage, des déformations de liaison oblongues et congrues (7) sont produites dans chaque bande (6), chacune avec une partie inférieure déplacée sur une distance au moins égale à l'épaisseur de la bande et généralement comprise entre 0,5 et 2 mm par rapport à la partie environnante de la bande (6). Chaque déformation de liaison (7) est délimitée par des limites longitudinales, où la bande s'interrompt, et des limites perpendiculaires où elle se poursuit.
