Definitions

  • the present invention refers to a device for the connection and the electric contact of terminals of electric and/or electronic components.
  • Such known devices for holding and contacting are usually provided for working on the limit condition of the plastic field of the material which constitute them, whereupon they often suffer drawbacks in particular working conditions.
  • the electric contact between terminal and interfaces is subject to temporary interruptions, caused by the imperfect electric union of the parts; said imperfect union is due to the fact that the interface-terminal junction happens in a stress condition that can overcome the limit of the plastic field of the materials: this involves therefore the possibility of failure of the system in which the device is used, especially if a functional constraint of permanent electric junction is required.
  • the cited problem is increased by the mechanical working tolerances, which can determine a dispersion of the pressure characteristics with which the junction between interface and terminal occurs.
  • the contact interface is subject to one or more superficial coinings, the condition of high plasticity of the interface being the same: such solutions, however, do not allow for the complete elimination of the cited drawbacks.
  • a contact spring is known, of complex geometry, which is inserted in a coating of insulated material and has a couple of shear-shaped elements, between which a pin connector is to be inserted.
  • the details of the junction principle of this device are not described in the cited document; however it is clear that, being it a spring provided for retaining pin connectors which should be removable, the device is not suitable for assuring a functional constraint of permanent electric and mechanic junction; also said device therefore has the above mentioned problems.
  • a device is also know, which allows for the quick union of an electric wire to a connector, wherein the device is expressively provided for coated wire having in the inside a plurality of annularly arranged compressed strands.
  • the device comprises a contact portion having a slotted opening, the width of which is lower than the diameter of the insulated coating of the wire; for the connection, the wire is pressed in the slotted opening, so that the insulating coating of the wire is broken ad the sides of the slotted opening get in contact with the wire strands, which slightly expand without distorting their annularly arrangement.
  • the contact portion requires strength rather than resilience, being the electric wire which adapts to the contact portion, and not the contrary.
  • Said device being specifically provided for coated wires with a plurality of compressed strands, is not suitable for the use with other type of electric wires and above all for the use with terminals or rheophores.
  • the aim of the present invention is that of eliminating the cited drawbacks of the known art and in particular to indicate a device for the connection of a terminal of electric and/or electronic components which, working within the full elastic field, allows the absorption of any eventual deformation, deriving for example from vibrations and/or thermal shocks.
  • reference number 1 indicates the holding and contact device according to the present invention, composed in the shown case by a small foil of normal brass, for example of the type 67 H10 or 67 H20, duly shaped; in the shown case, such a device 1 is practically constituted by a classic terminal of the "faston" type, for example of the type of those used in relays for motor vehicles: in particular, in the case of figure 1, with 1A is shown an interfacing zone, or contact interface, while with 1B is shown the more properly said "faston" portion, i.e. a portion for the connection of the device 1 to another interlocked device.
  • a contact element which has to be coupled to the interface 1A, i.e. the terminal of an electric and/or electronic component: for example, the element 2 may be the rheophore of a resistor, or the terminal of a coil for relays; for exemplification purposes, the contact element 2 has been represented in the figures as having a round section, premising the possibility to adapt the device for other shapes.
  • two opposite planes are indicated, being slant, in the illustrated case of 60° one to the other, that converge from the top of the interface 1A up to two contact hemisurfaces 4; said hemisurfaces 4, which in the illustrated specific case have a curved shaped, realize the "heart" of the interface 1A, or a contact zone for containing the element or terminal 2 in the permanent working position.
  • the shape of the hemisurfaces 4 depends upon the section of the contact element or terminal 2 to be used in conjunction with the interface 1A, so as also the diameter delimited by the hemisurfaces 4, that it is slightly lower than the diameter of the contact element or terminal 2.
  • the two slant planes 3 have the function of facilitating the positioning and the insertion of the contact element 2 within the hemisurfaces 4, and the function of facilitating the elastic deformation being necessary for the right positioning of the two parts in contact.
  • Reference number 5 indicates a flexion slot, obtained in the interface 1A under the area defined by the contact hemisurfaces 4.
  • the slot 5 even if the device object of the invention is not of the type having a prevalent elastic holding, has the function of allowing the minimum elasticity that consents the insertion of the contact element 2 between the hemisurfaces 4 in a stress condition of the interface 1A.
  • Reference number 6 finally indicates a suitable tool, making up part of a machine suitably equipped, provided for carrying out the elastic deformation of the interface 1A, by means of the widening of the slant planes 4; in the illustrated case the tool 6 has in fact a trapezoidal profile with an attack angle of 75°, i.e. having a dimension being greater that the angle of 60° defined by the two slant planes 3.
  • the device object of the invention is realized through a foil in an electrically conductive material in which are present:
  • the operation of the device according to invention is the following.
  • the contact element or terminal 2 is inserted in the notch defined by the slant planes 3, so as to be guided downwardly for resting on the upper zone of the hemisurfaces 4 (as mentioned, the diameter A is lower than the diameter of 2); successively, such a notch is resiliently deformed due to the action of the tool 6, which pushes down with a predetermined force, for example in the order of 10 Newton, and for a determined stroke, for example under the control of a suitable force transducer; such a lowering of the tool 6 has the effect of slightly widening the hemisurfaces 4, allowing the element 2 to penetrate between the same hemisurfaces; the cited operation is carried out within the full elastic field of the material constituting the interface 1A: due to the presence of the flexion slot 5, expressly dimensioned for satisfying the scope, the positioning of the contact element 2 is obtained, in the permanent contact zone defined by the two hemisurfaces 4.
  • the tool 6 is raised and the contact element 2 remains rigidly coupled between the hemisurfaces 4, in a field of elastic stress.
  • the attack angle of the tool 6 shall be of 75° and the force being necessary for producing the desired flexion within the full elastic field of the device will be of 10 Newton.
  • the main advantage of the described device is due to the fact that, according to invention, it is possible to obtain the coupling and the permanent electric contact by using materials having a high electric conductivity, even if not properly adapt to the "spring" function, such as for example of the common brass of the type 67 H10 or 67 H20; on the contrary, as mentioned in the opening of the present description, the known devices requires constructive materials being highly plastic, inasmuch as such known devices base their functioning just upon the plasticity of the material: as mentioned, however, this is a source of drawbacks.
  • the device 1 can be obtained starting from a foil of electrically conductive material, advantageously punched for realizing the slant planes 3, the hemisurfaces 4 and the slot 5.
  • the slot 5 must have a reduced width E, which could make problematic or impossible the punching process, it is possible to proceed in one of the following ways:
  • the device object of the invention may be used with terminal 2 onto which tin is present, being used as protective galvanic coat; in such a case, after the execution of the coupling operation as described above, a remelting phase of said tin may be provided, being obtainable in a very simple way, for example by means of an heating element: in this way it is therefore possible to obtain the interaction between the electric conduction due to the remelting of the tin and the electric conduction obtained by the contact pressure between the parts as described above, with a further increasing of the functional reliability of the same device.
  • Such an application is particularly indicated for heavy conditions of use, among which for example the connection of the ends of the coil of a relay, or other similar ones, where the connection is critic.
