Definitions

  • circuit board edge connector comprising an insulating housing defining an elongate cavity for receiving a daughter circuit board, the cavity having a base, a pair of parallel rows of passages extending through the base and communicating with the cavity on opposite sides thereof, and a plurality of electrical terminals each mounted in a respective passage and each having a mating portion in the cavity, a laterally offset portion adjacent the inner face of the base, and a connecting tail located beyond the outer face of the base and being laterally offset, by virtue of the offset portion, from the mating portion.
  • an electrical terminal provided with an enlarged laterally resilient mounting portion adapted to be force fitted into an internally metallically plated hole in a circuit board to make permanent electrical contact with the internal plating of the hole.
  • Such mounting portions are usually provided only on rectilinear pin or post terminals, in view of the high insertion force required to drive the mounting portions into the holes.
  • US-A-4 089 581 discloses a circuit board edge connector comprising an insulating housing defining an elongate cavity for receiving a daughter circuit board, the cavity having a base, a pair of parallel rows of passages extending through the base and communicating with the cavity on opposite sides thereof, and a plurality of terminals each mounted in a respective passage and each having a mating portion in the cavity, a laterally offset portion adjacent to an inner face of the base, and a connecting tail located beyond the outer face of the base, the connector being arranged in combination with a tool and a mother circuit board having a row of internally plated holes, each mating portion being spaced from that wall of the cavity which is adjacent the mating portion to permit insertion of a respective tool member between the wall and the mating portion to engage the offset portion of the terminal, each terminal being provided between its connecting tail and the outer face of the base with an enlarged laterally resilient mounting portion adapted to be force fitted into a respective hole in the mother board by driving the tool against the offset portion, the number and arrangement of the
  • the present invention is concerned with connectors having mounting sections adapted to make permanent or semi-permanent connections by effecting deformation of the holes and the hole plating on insertion and by means of resilient deformation exhibiting substantial stored energy to maintain good connection in a working environment.
  • Such mounting sections as disclosed in US-A-4 1 86 982 require substantial insertion forces, and it is an object to provide such a connector in which the relevant high forces can be applied whilst minimising risk of damage to the connector, the terminals and the board.
  • a circuit board edge connector comprising an insulating housing defining an elongate cavity for receiving a daughter circuit board, the cavity having a base, a pair of parallel rows of passages extending through the base and communicating with the cavity on opposite sides thereof, and a plurality of terminals each mounted in a respective passage and each having a mating portion in the cavity, a laterally offset portion adjacent an inner face of the base, and a connecting tail located beyond the outer face of the base, the connector being arranged in combination with a tool and a mother circuit board having a row of internally plated holes, each mating portion being spaced from that wall of the cavity which is adjacent the mating portion to permit insertion of a respective tool member between the wall and the mating portion to engage the offset portion of the terminal, each terminal being provided between its connecting tail and the outer face of the base with an enlarged laterally resilient mounting portion adapted to be force fitted into a respective hole in the mother board by driving the tool against the offset portion, the number and arrangement of the holes corresponding to the number and arrangement
  • a circuit board edge connector 10 comprises a rigid insulating housing 12 of plastics material, having a slot 14 opening into a mating face 16 of the housing along substantially its full length, for receiving a daughter circuit board (not shown).
  • the housing 12 has a base 26 ( Figures 2 and 3) through which extend passages 22 each communicating with one of the recesses 18.
  • Mounting flanges 28 are provided at the ends of the housing 12.
  • Each of electrical terminals 32 in the housing 12 comprises a mating portion in the form of a cantilever contact blade 34 for engaging the daughter circuit board, an intermediate offset portion 36 providing a shoulder, an enlarged resilient mounting portion 38 connected to the portion 36 by a rectilinear shank 37 extending substantially parallel to the mating portion 34 and a connecting tail 40 extending from the portion 38.
  • Each terminal 32 is mounted in one of the recesses 18, with its shank 37 extending through the corresponding passage 22, the mounting portion 38 of the terminal lying beyond the outer face 41 of the base 26 of the housing 12 and the portion 36 engaging the inner face 39 of the base 26.
  • the board 44 In order to mount the connector 10 on a mother circuit board 44 having internally metallically plated holes 42 therein, corresponding in spacing and arrangement to the connecting tails 40, the board 44 is positioned on a tool base 46, having spaced longitudinal grooves 48 therein, so that each hole 42 is aligned with one of these grooves.
  • the connector 10 is then aligned with the base 46 and is moved theretowards to insert each tail 40 of each terminal 32 through a respective hole 42 into the groove 48 aligned therewith, the portion 38 of the terminal resting on the plating of the hole 42, as shown in Figure 2.
  • a terminal driving tool 52 has legs 54, each leg 54 terminating in a shoulder 58 shaped snugly to engage the portion 36 of the corresponding terminal 32.
  • Each mating portion 34 is spaced from the adjacent wall 19 to permit the insertion of one of the legs 54 between the portion 34 and the adjacent wall 19.
  • Each mounting portion 38,_ which may be formed according to the teaching of US-A-4,186,982, comprises a pair of legs 60 joined at their ends and having surfaces which face and abut one another in a shear plane between the legs and with respect to which the legs are mutually laterally offset.
  • the legs 60 are compressed resiliently towards one another as the portion 38 is forced into the hole 42, in mutually contiguous frictional relationship.
