Definitions

  • the contact elements are formed by a film made of conductive material and that on both sides of the insulating body the bore ends are surrounded by recesses into which extensions of the contact elements engage.
  • the plated-through holes can be produced galvanically in one operation.
  • the contact elements can be attached to the two sides of the insulating body in one work step. This eliminates the cumbersome insertion of the mm-sized button contacts made of tangled wire or wire felt into the holes in the insulating body, as is required in the known solution.
  • the contact elements preferably consist of separate sections of a contact element mat. The contact elements can thus be produced together in a simple manner, for example from a film made of spring bronze, aligned on the insulating body and fastened to the latter, as will be explained in more detail below.
  • the fastening takes place mechanically in that on both sides of the insulating body the bore ends are surrounded by recesses, into which extensions of the contact elements engage.
  • FIG. 1 shows a schematic partial cross section through two carriers of contact points and a contact arrangement according to the invention arranged between them, which is to establish the electrical connection between the contact points,
  • FIG. 3 shows a section through the insulating body shown in FIG. 2 along line III-III in FIG. 2,
  • Fig. 7 is a partial section through a single contact element along line VII-VII in Fig. 6 and
  • Fig. 8 is a plan view corresponding to FIGS. 2 and 4 of an insulating body with two contact elements attached to it.
  • 10 and 12 denote two carriers, each having a plurality of contact surfaces 18 and 20 on their flat surfaces 14 and 16 facing each other.
  • the diameter and the mutual distance between the contact surfaces 18 and 20 is in the range of 1 mm, so that the contact surfaces 18 and 20 further because of this small extent can be called contact points.
  • Several hundred of these contact points 18 and 20 are arranged on the surfaces 14 and 16 in a regular grid dimension.
  • the first carrier 10 can be an electronic component, for example a processor, while the second carrier 12 can be a printed circuit board on which the component 10 is to be mounted.
  • the contact arrangement 22 comprises an insulating body 24 in the form of a thin plate (FIGS. 2 and 3), in which through bores or holes 26 are formed in an arrangement corresponding to the grid arrangement of the contact points 18 and 20.
  • the bores 26 each lie in a field of a grid, which is formed by grooves 28 intersecting at right angles in the two surfaces of the insulating body 24.
  • Each bore 26 is surrounded by an annular recess 30 which continues outwards in four short channels 32. In other words, there are four elevations 34 in the four corners of each field, which surround the bore 26 at a distance and are separated from one another by the channels 32.
  • the insulating body 24 described so far can be produced as a molded part made of plastic.
  • the bores 26 are provided with a plated-through hole 36 (FIGS. 1 and 5). This forms a conductive layer 38 covering the bore wall, which is continued on both sides of the insulating body 24 in a ring 40 that circumvents the bore 26.
  • the contact element mat 42 After the contact element mat 42 has been placed on the insulating body 24 provided with the plated-through holes 36, so that the contact elements 46 lie exactly over the grid fields of the insulating body 24 containing the bores 26, they are cut in a single operation with the aid of a punching and pressing tool, not shown the material bridges 48 are separated and the extensions 50 of the individual contact elements 46 are pressed into the channels 32 between the elevations 34 in such a way that the extensions 50 with the pointed claws 52 hook onto the walls delimiting the channels 32.
  • the contact elements 46 are firmly attached to the insulating body 24 and rest on the rings 40 of the respective plated-through hole 36.
  • the line length between two contact elements assigned to one another is very short.
  • the electrical connection is low in induction and has a low capacity.
  • the contact arrangement is extremely flexible in use with different distances between the contact points to be contacted, i.e. it is practically irrelevant for the production of the electrical connections whether the insulating body is somewhat thicker or thinner.
  • the contact arrangement according to the invention is orders of magnitude cheaper to produce than the known solution described at the outset, in which a separate contact button has to be inserted into each bore, it being necessary to ensure that this contact button leaves the bore to a certain extent protrudes.

Abstract

L'invention concerne un système de contacts pour assurer une connexion électrique entre une pluralité de premiers points de contact électrique (18) placés sur une surface pratiquement plane (14) d'un premier support (10), et un nombre correspondant de deuxièmes points de contact électrique (20) placés sur une surface pratiquement plane (16) d'un deuxième support (12). Ce système de contacts comprend un corps isolant plat (24) dans lequel des trous (26) sont pratiqués dans l'espacement des premiers et deuxièmes points de contact (18, 20), lesdits trous étant traversés chacun par un conducteur électrique (36). Dans ce système de contacts, les trous (26) sont munis de connexions transversales (36). Des éléments de contact (46) raccordés électriquement à chaque connexion transversale (36) sont fixés aux extrémités des trous, des deux côtés du corps isolant (24). A cet effet, les extrémités des trous sont entourées, des deux côtés du corps isolant (24), d'évidements placés à une certaine distance, dans lesquels s'engagent des prolongements (50) des éléments de contact (46).
