Definitions

  • the invention relates to the termination of ribbon conductors and more particularly to the termination of flat cable having ribbon conductors sandwiched between layers of insulation.
  • a terminal comprises a first metal plate portion from which upstands a cable penetrating tab-like lance having parallel opposite edge portions and a second metal plate portion provided with a socket aligned with the lance and having lips pushed out of the plane of the plate and converging towards their free ends to define a lance receiving mouth, the lance being proportioned to pass through the cable and into the mouth.
  • a disadvantage of the prior terminal is that the force required to obtain a satisfactory electrical connection between the contact rings and the cable conductor is relatively high. Furthermore, as the lance-receiving mouth of the prior terminal is circular, there may be risk of relaxation of the connection in view of the small area of direct contact between the edge portions of the tab-like lance and the socket lip.
  • the terminal can be applied with simple tooling and without need for a high force. It is further preferred that the resulting terminations will have a relatively high current carrying capacity.
  • the lance receiving mouth is slot-form, the arrangement being such that, after penetration of the cable by the lance, a portion of the cable conductor will be drawn into the mouth by the lance compressed between and in direct contact with, a face of the lance and one lip by insertion of the lance into the socket.
  • the conductor portion is compressed between two metal parts for a distance equal to the entire width of the tab ensuring a good electrical connection.
  • Each interface of the connection is metal to metal resulting in a gas tight connection.
  • the lance has been struck out from the first metal plate portion providing an aperture into which a portion of the cable is deformed during termination, the face of the lance engaged by the conductor portion being adjacent the aperture.
  • an electrical connection between a ribbon conductor and first and second metal plate portions of an electrical terminal in which a tab-like lance having parallel opposite edge portions upstanding from the first metal plate portion and a free end penetrates the ribbon conductor and is received in a socket provided in the second plate portion, the socket having lips pushed out of the plane of the second plate portion and converging towards their free ends to define lance-receiving mouth, the lance passing through the cable and into the mouth, the lance-receiving mouth being slot-form and a portion of the conductor having been drawn into the mouth by the free end of the lance and compressed between and in direct contact with one lip and a face of the lance.
  • ribbon conductor material has been displaced from between the face of the tab and the one lip further into the socket.
  • a terminal for very thin foil-like conductors includes opposed metal plate portions each formed with raised teeth which engage the conductor where the plate portions are urged together.
  • a disadvantage of the known connector is that all of the teeth must pierce and tear the conductor during termination to effect connection with the result that not only is a relatively high termination force required but the conductor is substantially weakened by the piercing and tearing. It would not be practicable to use the known connector to terminate flat cable in which the ribbon conductor is relatively thick in view of the high force required.
  • the splice terminal 11 is stamped and formed from a single piece of sheet metal stock, (approximately 4 mm (.016 inches) thick Cu alloy 195), and comprises first and second plate portions 12, 12' and 13, 13' at respective opposite ends for terminating respective ends of flat cable 20, 20'.
  • Each first plate portion 12 or 12' is integrally joined to its respective second plate portion 13 or 13' by an integral web 14 or 14'.
  • a series of tab-form lances 15 and 15' having parallel opposite edge portions are located in cruciform fashion on respective first plate portions in alignment with a corresponding series of sockets 16 and 16' located on the respective second plate portions.
  • Each lance 15 or 15' is pushed out of the plane of the plate portion providing an aperture 17 or 17'.
  • Each socket 16 or 16' has lips 19 pushed out of the plane of the plate portion and converging towards their free ends to define a slot-form lance receiving mouth 21.
  • the edges 22 of the lips 19 are relatively sharp being defined by piercing through impressed portions of the plate to provide the mouth.
  • the flat cables comprise ribbon conductors 23 of 2.286 mm to 3.556 m (.009 to.014 inches) thick sandwiched between first and second layers of insulation 24 and 25 (Trade Mark: "Mylar”) approximately 1.778 mm (.007 inches) thick and a proprietary adhesive.
  • a cable is inserted between first and second plate portions 12 and 13 and a plier type tool having planar pressing faces is used to apply a force of approximately 4488 N (1,000 pounds) to the plate portions forcing the lances through the cable into the mouths drawing with them portions 27 of the ribbon conductor.
  • a portion 28 of the insulation is severed by the edge 22 of the lip 19 and ultimately expelled from between the conductor and lip.
  • Conductor material is displaced from between the faces of the lances and the lips 19 leaving portions 26 of reduced thickness compressed between and in direct contact with the faces of the lances and the lips.
  • Portions of ribbon conductor and the other layer 25 of insulation are deformed into the respective apertures 17. Forces acting on the free end 31 of the lance during termination broaden the free end assisting in preventing relaxation of the connection and are transmitted through the lance to the portion 26 of the conductor enhancing the compressive force.
  • the resulting termination is capable of carrying relatively high currents of up to 60 amps and yet the termination is of relatively low height.
  • the termination is particularly suitable for undercarpet flat cable.
