Definitions

  • This invention relates to electrical connector blocks for a flat ribbon cable having a plurality of conductors lying side by side in an insulating ribbon.
  • Transient protectors absorb this energy and minimise damage or prevent excessive voltage from leaving the equipment.
  • the transient protectors are soldered onto a circuit board or to a connector. High density boards, however, have little room for such transient protectors.
  • standard insulation displacement connectors do not have exposed metal where the transient protectors can be added.
  • CRTs cathode ray tubes
  • high voltage in CRTs could propagate outside the enclosure of the devices via signal lines connected to the devices. Such propagation can cause fire, shock and/or equipment damage.
  • the high voltage in the signal wires can arc over to other circuits or bare metal. If these wires are connected to equipment in a hazardous location, such as in the proximity of flammable or explosive material, this arc can cause ignition of this material.
  • any voltage on any signal leading out of a CRT be less than 250 volts ac with respect to ground (earth).
  • the anode voltage in a CRT could be 14,000 to 35,000 volts.
  • the capacitance of the anode could be 500 to 2,500 pF.
  • Transient protectors for lines leaving a CRT would thus be desirable, particularly in view of the small amount of space which is generally available on circuit boards of such devices.
  • EP-A-0 043 627 discloses an electrical connector block in which terminal contacts having insulation-piercing ends for connection with conductors of a flat ribbon cable are arranged in two staggered rows.
  • the prior art does not teach the placement of components such as signal conducting resistors or surge suppression devices in shunt or parallel with two or more conductors in a ribbon cable.
  • an electrical connector block for a flat ribbon cable having a plurality of conductors lying side-by-side in an insulating ribbon comprising:
  • Preferred embodiments of the present invention described in detail hereinbelow provide a connector block which is particularly suited for a ribbon cable and provides contact to conductors in the cable as well as locations for mounting components on the block, which components are connected between conductors in the cable or between a conductor and a ground connection.
  • the preferred connector blocks are provided on the ribbon itself so that there is no need for access to or space on a circuit board to which the ribbon may be connected. This also facilitates retrofitting of pre-existing assemblies.
  • the preferred electrical connector blocks are simple in design, rugged in construction and economical to manufacture.
  • Figures 1, 2 and 3 show an electrical connector block 10 for a flat ribbon cable 12 having a plurality of side-by-side conductors 14 to 17 which are enclosed within an insulating ribbon 22.
  • the block 10 comprises a top cover 30 which covers components connected to a base member or base 32.
  • the top cover 30 includes arms 34 with hooks or shoulders 36 which engage under a bottom cover 38.
  • the arms 34 have the dual purpose of holding the cover 30 on the base 32 as well as holding the bottom cover 38 up into engagement with the ribbon 12.
  • Spring metal clips 40 are provided on both ends of the block 10 and on either side of the arms 34 for holding the base 32 to the bottom cover 38.
  • the base 32 includes a plurality of terminals or contacts 42 to 46.
  • Each contact 42 to 46 extends through the base 32 and includes a lower insulation piercing end.
  • the lower insulation piercing end can be bifurcated (not shown) or tine-shaped. It is important the insulation piercing end of each of the terminals or contacts 42 to 46 be sufficiently long to pierce the insulation of the ribbon 22 and come into contact with one of the conductors 14 to 17 in the ribbon.
  • the bottom cover 38 is provided with a plurality of cavities or recess slots 50 which are disposed under each conductor to accommodate any displacement of the ribbon 22 after it has been pierced by the insulation-piercing ends of the terminals or contacts 42 to 46.
  • the terminals or contacts 42 to 46 automatically pierce the insulation and come into contact with the conductors 14 to 17 when the block 10 is assembled.
  • a plurality of components 52, 53 and 54 can be connected, for example by soldering, between terminals in a first row of terminals containing the contacts 42, 43 and 44 and a second row of terminals containing the contacts 45 and 46.
  • These components may, for example, be resistors or diodes.
  • the component 52 is shown connected between adjacent conductors 14 and 15 by virtue of its being connected to the terminals 42 and 45.
  • the component 53 is shown connected between terminals 43 and 46 and thus interconnects adjacent conductors 16 and 17.
  • Components can be arranged in other manners, however, to connect any one conductor with any other conductor and also to provide this connection with a selected component, such as a resistor or diode.
  • Figures 5 and 6 illustrate an embodiment of the invention used as a transient protector.
  • the base 72 includes a first row of terminals or contacts at 74 and a second row at 76.
  • a bus line 78 having slots 80 is fixed near the centre of the base 72.
  • Transient protection for each conductor including conductors 19, 20 and 21 is provided by a ground wire 82 which has one end fixed, for example by clamping or soldering, to the bus line 78.
  • Figure 7 shows a ribbon cable 12 connected between a circuit board 90 and a standard displacement connector 92.
  • the connector block or box 10 is engaged and is shown with the ground wire 82 connected by a nut and bolt combination to a chassis 94 which supports the circuit board 90.
