Definitions

  • the present invention relates to a contact device of the described type, by which the said disadvantages are eliminated and which may be used inorder to get a great number of contact possibilities in alimited space.
  • the contact device consists of one contact with a number of parts being elastic in a direction perpendicular to the contact surface and a second contact consisting of a contact pin.
  • the contact provided with elastical parts consists of a packet of metal laminas, the plates of which being provided with a slit from one edge of the plate in such a way that there is formed an aperture in the contact perpendicular to the surface of the separate laminas and into which the contact pin may be inserted.
  • the laminas are suitably of an oblong, rectangular form.
  • the slit in the laminas which at the edge of the plate or in the vicinity thereof suitably has a contraction is given such dimensions' that a contact pressure arises when the contact pin is brought into it as the material on each side of the slit is elastic.
  • the contact in spite of the little thickness of each lamina, has good stability as a number of plates are put together surface to surface and soldered or welded at the non-split parts of the laminas. It is evident' that a very great number of individual contact possibilities are produced by means of this construction.
  • the dimensions of the contact device can be made very small in the longitudinal direction of the complete contact strip,
  • the outer laminas in the packet may be made thicker than the inner ones.
  • Fig. l is a side elevational view of a flat pin which constitutes one of the contact elements.
  • Fig. 2 is a similar view taken at right angles 7 to the edge shown in Fig. 1.
  • 3 is a side elevational view of the laminated contact member.
  • Fig. 4 is a similar view showing the edges of the laminations.
  • the other contact member includes a plurality of relatively thin metal strips 2 arranged in facial relationship. 3 indicates the slit in the oblong rectangular metal strips 2, into which the contact pin I is to be inserted.
  • the legs I obtained in the plate by taking away the material in the slit 3, may suitably be provided with extensions 5 intended to produce small contact surfaces and a comparatively high contact pressure.
  • the slit 3 is of the same width as the pin 1 or somewhat wider and the distance between the extensions 5 on the legs somewhat smaller than the thickness of the pin.
  • the non-split parts of the laminas are wholly or partly soldered or welded together. In this manner a number of contact possibilities corresponding to the number of plates is obtained, each one with a comparatively high contact pressure although the dimensions of the contacts are very small in the longitudinal direction of the final contact strip.
  • a stack composed of a pin. ality of relatively thin flat elongated platelike members of flexible material arranged in facially contact relation, means joining said members together at one end to maintain the stack form thereof, said members having registering recesses at the opposite ends forming spaced legs capable of resilient motion in the direction of the plane of the members, said legs having extensions within the recesses presenting at the edges thereof a multiplicity of contact surfaces of small area capable of relative movement incident to the flexing of the legs in conformity with the surface irregularities of a contact member engaged therewith.
  • a contact device a plurality of juxtaposed elongated metal laminations, each of said laminations having a longitudinally arranged slot in an end portion, and means maintaining the metal laminations in said assembled relationship.
  • a contact assembly for a jack switch comprising, a plurality of elongated juxtaposed metal laminations, said laminations having substantially aligned lengthwise slots therethrough so as to be resilient in a. plane of the lamination, and means adjacent unslotted portions of the laminations for maintaining the laminations in said juxtaposed relationship.
