Definitions

  • the present invention relates to an insulation displacement contact device which is suitable to provide an insulation displacement contact (IDC).
  • IDC is also known as insulation piercing contact (IPC) and usually denotes an electrical connector designed to be connected to at least one conductor of an isolated cable by a connection process which forces a selectively sharpened blade or blades through the insulation, bypassing the need to strip the conductors of insulation before connection. If carried out properly, the connector blade cold-welds the conductor, thereby making a theoretically reliable gas-tied connection.
  • IDC contact design usually applies an IDC contact which is traditionally made of a single thin metal plate, wherein a copper alloy is usually preferred to make said metal plate, which is provided with a contact slot adapted to receive the at least one conductor of the cable.
  • the mouth of said slot is usually designed to act as a blade to cut the insulation of the cable when the blade is inserted into the contact slot.
  • Examples of an IDC made of a single piece of thin metal plate are discussed e.g. in DE 90 06 417 U1 , disclosing various configurations of the mouth and the contact slot within the metal plate adapted to receive the cable, and e.g. in EP 1 177 603 B1 , EP 1 212 811 B1 , EP 1 122 820 B1 or EP 0 893 845 B1 , each disclosing an external clamping means adapted to force cooperating blade surfaces against each other to thereby press the blade surfaces against the cable received in the contact slot.
  • Those additional clamping means are to secure a good contact between the at least one conductor of the cable and the cooperating surfaces of the contact slot.
  • shock or vibration may loosen the at least one conductor within the slot. Strain relief within the conductor or the material forming the IDC will likewise affect the electrical contact during the desired working lifetime of the IDC.
  • EP 0 435 292 B1 discloses an IDC providing improved flexibility performance.
  • This prior art discloses an IDC made of a single piece of metal by cutting and bending. The contact slot is provided between two blade sections, which blade sections are defined at free ends of a basically U-cut sheet metal piece, which U-cut sheet metal piece is bent in a U-form to form blade sections parallel to a foot section with a bridge section extending perpendicular to the foot and the blade sections and interdisposed there between.
  • the blade sections are not directly connected to each other. The only direct connection is provided by the foot section at the end opposite to the blade section.
  • the foot section is provided with a hole adapted to receive and hold the cable to be contacted with the IDC by encompassing the insulation thereof and grasping the cable within the IDC. Due to the length of the bridge section, the IDC of this prior art provides increased flexibility and deflection capability.
  • Fig. 8 of the present application shows the behavior of prior art IDCs.
  • a "conventional IDC” the behavior of a single metal piece IDC essentially in accordance with DE 90 06 417 U1 or DE 10 2011 121 943 A1 is depicted.
  • "Improved IDC” shows the behavior for an IDC in accordance with the aforementioned prior art EP 0 435 292 B1 .
  • the present invention specifies an insulation displacement contact device having two blade surfaces defining the contact slot, wherein said blade surfaces are provided by a first blade element and a second blade element being physically separated from each other.
  • the different blade elements are movable relative to each other and biased against each other by spring means.
  • the first blade element provides the one and the second blade element provides the other of the two blade surfaces.
  • the IDC makes it possible to repeatedly repair the wire terminations by moving the blade surfaces away from each other against the force of the spring.
  • the blade elements are usually provided movable in a translational fashion such that the blade surfaces defining the contact slot are provided within a single plane and strictly move within said plane in longitudinal direction, i.e. without tilting as the prior art blade elements do, wherein the blade sections are pivotally connected to a common base or foot section of the sheet material.
  • the material forming the blade elements can be selected to be a material providing a good electrical conductivity, such as copper and copper alloys. The elasticity and strength of the material is not an important parameter for the selection of an appropriate material for forming a blade element.
  • the blade elements each can be made of different materials to e.g. provide blade surfaces made of a material having a good electrical conductivity and a low electrical transition resistance between the blade surface and the surface of the conductor, whereas the remaining parts of the blade elements can be made of a material selected to attain other required properties, such as e.g. the sliding properties for allowing relative movement of the first and the second blade elements relative to each other.
  • each separate blade element is usually made of a single sheet of metal, preferably copper or a copper alloy, by cutting and bending.
  • a coating may be applied to the surface of such sheet of metal, in particular to the surface defining the contact slot.
  • the spring means can be made of any suitable material providing sufficient elasticity, including metal or plastic.
  • the material defining the spring means does not necessarily have to be electrically conductive. Further, the spring means may be provided as a unitary portion of one of the first or the second blade elements.
  • the material and design of the spring means is selected in view of economical constraints and the desired flexibility and durability.
  • the spring means can in particular be made of steel, in particular spring steel.
  • At least one of the blade elements is to provide means for electrically contacting the IDC to a substrate, e.g. a PCB or another conductive device like a cable or a connector or the like.
  • a substrate e.g. a PCB or another conductive device like a cable or a connector or the like.
  • at least one of the first or the second blade elements defines a pin, usually made by cutting and bending sheet metal forming the respective blade elements, adapted to be received within a hole of a PCB, and electrically connected to a conductive path within said PCB.
  • the first blade element is formed by a terminal base element.
  • a terminal base element in the meaning of this preferred embodiment provides at least one guide surface for guiding a movement of the second blade element relative to the first blade element. More preferably, the terminal base element provides all means for connecting the IDC to a support, such as a PCB, whereas the second blade element is slidably held only by the first blade element, i.e. the terminal base element.
  • the first and the second blade elements each define a further blade section adapted to define there between a second slot adapted to either clamp the insulation or to contact the conductor of a cable.
  • the first and the second blade elements define two separate slots, one of which is a contact slot adapted to electrically contact the at least one conductor of the cable, whereas the other slot may provide additional electrical contact to the conductor of said cable by likewise contacting said conductor or mechanical clamping of the cable within the IDC by clamping the insulation of the cable.
  • the driving force of the blade sections against the outer circumference of the cable, i.e. the insulation thereof or the conductor is usually triggered by the same spring means, preferably a single spring element.
  • the first blade element is a bent sheet metal piece providing a first biasing arm.
  • the second blade element is likewise a bent sheet metal piece providing a second biasing arm.
  • Those first and second biasing arms usually extend essentially parallel to the longitudinal direction of the contact slot to thereby define an abutment face suitable to receive the spring force of a spring element.
  • a respective spring element is preferably arranged between the first and the second biasing arm.
  • the first biasing arm is arranged below the second blade surface in extension direction of the contact slot and the second biasing arm is arranged below the first blade element in respective extension direction of the contact slot.
  • the blade surfaces defining the contact slot do not necessarily have to be provided with a sharpened edge throughout their entire length to cut the insulation of the cable. However, on a regular basis, the blade surfaces define a chamfered mouth defining a cutting section and leading to the contact slot.
  • the insulation is usually perforated and cut such that the blade surfaces can directly contact the conductor of the cable upon insertion thereof into the contact slot.
  • the IDS comprises a spring element which is used to secure, i.e. hold, the first and second blade elements.
  • the spring element usually has a first fastening arm segment which is attached to the first element and a second fastening arm segment which is attached to the second blade element.
  • the spring element according to this constitution is made of a metal sheet which in turn is made of spring steel. Holding of the two blade elements is preferably attained by a form fit between the blade elements and the spring element.
  • the blade elements may have holes formed by cutting of the sheet metal defining the blade elements and projected by a fastening projection. This fastening projection may be the free end of the spring arms of the spring element.
  • the fastening projections may have smaller dimensions than the dimension of the respective spring arm.
  • the spring element is provided with a mounting projection.
  • This mounting projection is e.g. adapted to be received in a mounting hole of a support, such as a PCB, to mechanically secure the spring element to said support.
  • the mounting projection does not form part of the electrical path on a regular basis.
  • the mounting hole of the PCB is not electrically connected to the conductive paths of said PCB.
  • the blade elements are of course electrically connected to the PCB and the conductive paths thereof. While electrical contact between one of the first and the second blade elements and the PCB will be sufficient and can be embodied according to the present invention, two electrical contacts are usually and preferably selected such that both of the first and the second blade elements are both contacted with an electric path of the substrate.
  • the spring element supports the first and second blade elements
  • the mechanical support between those blade elements and the substrate can be weak.
  • an elastic support of the first and second blade elements relative to said substrate is preferred to allow relative movement of the blade elements.
  • At least one of the first and the second blade elements define an elastic section arranged between a pin provided by respective blade element and the blade surface such that the blade surface is allowed to move relative to the substrate/PCB.
  • the elastic section can e.g. be provided by a very thin but straight leg or beam made by cutting the sheet metal forming the blade element.
  • the elastic section may have a meandering or curved constitution to improve relative movement of the blade surfaces of the two blade elements relative to each other to cope with varying sizes of the cables to be inserted.
  • the spring element is only secured to the substrate via the first and the second blade elements.
  • the spring element is just a connection for connecting the separate blade elements with each other in an elastic way such that they can move relative to each other to define a varying contact slot adapted to receive cables of different size.
  • Mounting of the IDC and, thus, securing of the entire IDC to the substrate/PCB is attained by at least one pin provided by at least one of the first and the second blade elements and received in a hole of the substrate/PCB.
  • One of the blade elements can be arranged fixed relative to the substrate/PCB.
  • the other blade element can be movable and pretensioned against the first blade element and does not need to be connected to the substrate/PCB.
  • At least one of the first and the second blade element defines a guiding surface extending essentially perpendicular to a pin.
  • This guiding surface is adapted to be guided on the surface of the substrate/PCB such that the movement of the two blade elements relative to each other is achieved against the pretension of the spring element connecting the two elements with each other in an elastic way while further alignment of the two elements is provided by the guiding surface and, thus, the surface of the plain PCB.
  • At least one of the first and the second blade element is portably received within a receiving hole of the substrate/PCB.
  • the respective blade element has a pin which extends essentially perpendicular to the guiding surface and is received within the hole of the substrate/PCB.
  • the spring element may only be secured to the first and the second blade elements and not the PCB or another substrate.
  • the IDC device may only be connected to the substrate via one and only one pin received within the hole.
  • both blade elements are provided with a pin to be received in respective holes of the substrate/PCB for electrical and/or mechanical connection thereto.
  • the present invention provides an IDC device adapted to receive a wider range of cables.
  • the IDC device of the present invention is able to terminate considerably larger wires and/or wires with a high number of strands of different design.
  • the coupling of the connector to the IDC device is not limited by the material properties of the bent sheet material forming the IDC. Instead, movability is largely achieved by the spring performance of spring means bypassing two individually movable and physically separated blade elements against each other to thereby define a contact slot with blade surfaces limiting said contact slot, movable relative to each other to a great extent and pressed against each other by the force of the spring means.
  • the high contact deflection range provided by the inventive solution also makes repeated repairs of the wire terminations possible.
  • Fig. 1a and 1b illustrate the principle of the insulation displacement contact device according to the present invention consisting of a first blade element 10, a second blade element 20 and spring means 30 interdisposed between a first biasing arm 11 of the first blade element 10 and a second biasing arm 21 of the second blade element 20.
  • Each blade element 10, 20 has blade surfaces 12, 22 facing each other and defining a contact slot 40 adapted to receive a cable 50 in a fashion depicted in Fig. 1 b.
  • Fig. 1a The free end of the blade surfaces 12, 22 are diverging outwardly to define cutting sections 13, 23.

  • the two blade elements 10, 20 are physically separated from each other.
  • a blade section 24 of the second blade element 20 is depicted to be arranged above a first transverse beam of the first blade element 10 extending transverse to the longitudinal extension of the contact slot 40 and identified with reference numeral 15.
  • the assigned transverse beam 25 of the second blade element 20 is thus guided by an upper surface of the first transverse beam 15 to allow a sliding movement of the first blade element 10 relative to the second blade element 20. From the lateral ends of the transverse beams 15, 25, the biasing arms 11, 21 extend in a direction parallel to the extension direction of the contact slot 40.
  • the cable When inserting the cable 50 into the IDC device depicted in Fig. 1 , the cable abuts against the cutting sections 13, 23 and is usually cut such that a gap is formed in an insulating material 51 of the cable 50 to thereby expose multiple strands 52 providing the conductor of the cable 50.
  • the blade surfaces 12, 22 are biased against the strands 52 to make electrical contact between the first and second blade elements 10, 20 and the conductor 52 of the cable 50.
  • the force with which the blade surfaces 12, 22 abut against the conductor 52 depends on the force of the spring element 30, which force can be varied as required for providing the desired force, i.e. pressure, to electrically clamp the conductor 52 between the blade surfaces 12, 22.

An underside of the base section 16 opposite to the blade sections 14 is projected by four securing lugs 61 adapted to be inserted into an assigned fastening hole of a printed circuit board.
  • At least one of those lugs 61 defines a pin 62 for electrically contacting the terminal base element 10 to a conductive path of the PCB.
  • all lugs 61 can be pins, provided that all respective fastening holes of the PCB are connected to electric paths of the PCB.
