Abstract

Contact pins 10 of a circuit module 11 are mounted in electrical contact with spring conductors 12 supported in base block 13. Locking plate 14 is slidably received in a U-shaped upper portion 15 of base block 13, and is retained by lips 16 in a trapped relation on block 13. Plate 14 can be held in a load position where its corners 17 are received by ledges 18 of resilient arms 19 of the base block 13. In this load position, holes 20 in locking plate 14 are aligned with an open portion in block 13, such that pin 10 is inserted in block 13 without contacting spring 12.

Zero Insertion Force Mounting Device

Contact pins 10 of a circuit module 11 are mounted in electrical contact with spring conductors 12 supported in base block 13. Locking plate 14 is slidably received in a U-shaped upper portion 15 of base block 13, and is retained by lips 16 in a trapped relation on block 13. Plate 14 can be held in a load position where its corners 17 are received by ledges 18 of resilient arms 19 of the base block 13. In this load position, holes 20 in locking plate 14 are aligned with an open portion in block 13, such that pin 10 is inserted in block 13 without contacting spring 12.

When the circuit module 11 has been inserted on locking plate 14, plate 14 is manually displaced to its locked position where corners 17 are trapped by ledges 21 and pins 10 are pressed against the contact springs 12. Assembly of contact springs 12 in base 13 is facilitated by preformed grooves 22, which give lateral support and alignment to the spring contacts 12.
