Definitions

  • This invention relates generally to electrical connectors and, more particularly, to connectors into which the edge of a printed circuit card can be inserted with zero insertion force.
  • an edge card connector of the type having opposed rows of elongated terminals having spaced contacts at their free ends, a cam extending lengthwise of the rows and an an elongated cam follower for each row of terminals.
  • the followers are located outside the rows, beneath outwardly bowed portions in the lengths of the terminals, and are adapted to engage the bowed portions and move them into engagement with an inserted card. Then, the bowed portions are stressed to achieve a contact wipe.
  • Shank portions of the terminals extend through a terminal block and present rows of projecting tails below the block adapted for connection to a circuit board.
  • the cam followers are enclosed within a one-­piece, non-moving housing.
  • the terminals which are preferably staggered and alternately long and short in each row emerge from a surface of the terminal block.
  • the cams are longitudinally movable in channels defined by the rows of terminals, the housing and the terminal block.
  • the present invention provides a a zero insertion force connector for connecting the edge of a printed circuit card to a circuit board, having
  • the edge card connector is shown to include a housing 10 for a terminal block 12 and cams 14,15.
  • Housing 10 has openings 16 for detents 17 on terminal block 12.
  • a handle 18 is pivotally attached at 19 to block 12 and has pin fitted into slots 20 in the cams.
  • Handle 18 is grooved, as shown at 22, to receive one edge of a printed circuit card 24 when the handle is down to a horizontal position. From there, card 24 can be pushed laterally into an open-ended slot 26 in the top wall of housing 10 to the point where it is stopped by a pin 28 and another pin 30 on the card is seated in notches at the other end of housing 10. Then, cams 14,15 are moved to the positions shown in Fig. 1 by raising handle 18.
  • cam 14 has ramps 32 which coact with similarly but oppositely configured projections 34 on a cam follower 36 in housing 10. Fingers 38 on follower 36 limit the movements of cam 14 which movements raise and lower the follower.
  • follower 36 is shown in its lowered position in Fig. 2A and in the raised position in Fig. 2B.
  • each follower 40 there is another follower 40 associated with cam 15.
  • each follower is recessed to present a comb-like array of thin blades 42 adapted to engage and stress bowed portions 44 of terminals 46 when followers 36,40 are raised from the position shown in Fig. 3 to the position shown in Fig. 4.
  • Seats between the blades 42 engage and stress the bowed portions 48 of terminals 50.
  • the bowed portions are at different levels, alternately high and low, with a high bowed portion 44 in one row opposite a low bowed portion 48 in the other row.
  • the tops of blades 42 present high surfaces and the space between the blades present low surfaces positioned to engage the bowed portions of the terminals 46,50.
  • Terminals 50 are relatively short and have straight shank portions 52 leading to solder tails 54. Although solder tails have been shown herein, other configurations such as wire wrap tails, pins or posts could be used.
  • Longer terminals 46 have shank portions 56 bent outwardly (Figs. 3-5) to solder tails 58.
  • Shank portions 52,56 are embedded in the molded terminal block 12 and tails 54,58 project therefrom.
  • Tails 54,58 are adapted for placement in an apertured printed circuit board 59.
  • each terminal has a card-engaging contact 60 in the form of a coined dimple and is rounded to facilitate entry into the space between partitions 62 in housing 10 as the connector is assembled and as the contacts are spread.
  • Blades 42 on followers 36,40 are also confined between the partitions to insure alignment with the bowed portions. In addition, they prevent longitudinal movement of the followers as they are raised and lowered by cams 14,15.
  • each long terminal 46 has its tail 58 offset laterally from shank portion 56.
  • the short terminals 50 have similarly offset tails 54.
  • the terminals in adjacent longitudinal rows have their tails offset longitudinally in opposite directions. Because of that feature and because of the outwardly extending shank portions 56 in the long terminals 46, there are four tails in each lateral row, i.e., for two rows of opposed terminals, there are four longitudinal rows of tails.
  • cam followers 36,40 are enclosed within one-piece, non-moving housing having side walls attached to the sides of terminal block 12 and having top and end walls which are slotted to form slot 26 for the receipt of card 24.
  • the end walls also have openings to accommodate longitudinal movement of cams 14,15 within the housing.
  • terminals 46,50 emerge from the top of terminal block 12 in two rows, and the cams 14,15 are longitudinally movable within longitudinal channels defined by the rows of terminals, the housing 10 and the top surface of the terminal block 12.
