  • a card connector 2 for accommodating a PC card 1 is shown as having a card connector section 3 and a counter connector section 4 to be integrally connected thereto.
  • card connector section 3 includes an insulating housing 5 mounting two lateral arrays 7 of pin terminals 6 to be mated with corresponding receptacles of two mating PC cards 1 and two rows of grounding terminals 9 adapted to contact the outer casing of each card 1.
  • Lateral arrays 7 of pin terminals 6 are arranged vertically parallel to one another in upper and lower spaced-apart levels, and each array includes upper and lower rows of pin terminals 6 to mate to each card.
  • Grounding terminals 9 are similarly arranged at two levels, so that each row of grounding terminals 9 extends above each upper row of pin terminals in each lateral array.
  • Pin terminals 6 of both sets of lateral arrays are mounted in insulating housing 5 such that their "L"- shaped connection tails 8 are aligned in a single row on the rear side of insulating housing 5. The spacing between these in-line connection tails 8 is half the distance of the interval between pin terminals 6.
  • Grounding terminals 9 extend above each upper row of pin terminals 6 and are aligned vertically to make contact with the outer surface of each PC casing when PC cards 1 are inserted into the card connector.
  • each ground terminal rod 10 bridges two adjacent grounding terminals 9. Furthermore, as seen in FIG. 8, each ground terminal rod 10 projects from a bottom 5a of insulating housing 5 to provide two grounding ends 10a.
  • each card eject mechanism 12 comprises an eject rod 13, a push rod 14 with a push-button at one end thereof, and an intervening gear 15 between eject rod 13 and push rod 14.
  • Eject rod 13 has a hook 18 at one end to catch and eject the front end of the respective PC card.
  • push rod 14 is pushed rearward to drive eject rod 13 forward and eject the card.
  • a rectangular metal shell 19 is mounted on an upper surface of insulating housing 5.
  • At least one longitudinal sidewall of the rectangular shell has slots 11 which cooperate with longitudinal arm 5b of the housing to guide PC card 1, and rear wall 26 of rectangular shell 19 covers the rear side of counter connector section 4.
  • Insulating housing 5 has an opening 20 on its front side to accommodate insertion of the PC cards.
  • ground terminal rod 10 is mounted to insulating housing 5 in the direction indicated by arrow "A" and passes through both levels of grounding terminals 9.
  • grounding terminals 9 are fabricated by stamping and forming an elongated thin metal sheet. Each grounding terminal has an engagement aperture 9a offset relative to its longitudinal center axis to permit one leg of ground terminal rod 10 to pass therethrough.
  • Engagement aperture 9a has two cantilever-like contacts 9b formed therein to contact ground terminal rod 10.
  • counter connector section 4 includes signal terminals 22 and ground connection terminals 23 mounted in its generally "L"-shaped insulating housing 21.
  • One row of signal terminals 22 is inserted from the bottom of insulating housing 21 and extends along an upright wall 21a of insulating housing 21.
  • the other row of signal terminals 22 is inserted from the bottom of insulating housing and is spaced vertically away from upright wall 21a.
  • Signal terminals 22 are arranged at the same interval, i.e. have the same spacing, as connection tails 8 of pin terminals 6, and engagement tails 22a of signal terminals 22 extend to the front of the card connector. As seen in FIG.
  • each ground connection terminal 23 has two sections integrally connected by a central engagement piece 27, and these sections each have engagement apertures 24 to conform to and make contact with the two parallel legs of ground terminal rod 10.
  • Each engagement aperture 24 has a "U"-shaped cantilever-like contact 24a formed therein to contact one leg of the ground terminal rod.
  • Ground connection terminals 23 are fabricated by stamping and forming an elongated thin metal sheet. The ground connection terminals are mounted in housing 21 by inserting them into the horizontal wall of the housing 21. Each ground connection terminal 23 has a solder tail 23a extending forward from a lower surface of insulating housing 21. Horizontal wall 21b of insulating housing 21 includes through holes 25 to accommodate the ends of legs 10a of ground terminal rods 10.

  • the card connector 2 thus provided can be mounted on an underlying circuit board (not shown) by soldering solder tails 22b of signal terminals 22 to the signal conveying circuit conductors of the circuit board, and by soldering solder tails 23a of ground connection terminals 23 to the grounding circuit of the circuit board.
  • pin terminals 6 are connected to the signal conveying circuit of the circuit board via signal terminals 22 and grounding terminals 9 are connected to the grounding circuit of the circuit board via ground terminal rods 10 and ground connection-terminals 23.
  • ground terminal rods 10 are connected to the grounding circuit of a given circuit board via ground connection terminals 23. That is to say, ground terminal rods 10 are connected to the grounding circuit of the circuit board at the bottom of insulating housing 5.
  • This arrangement makes it unnecessary to use a relay circuit board on the rear side of card connector 2, thus providing a substantial reduction in the longitudinal size of card connector 2, and permitting the mounting of additional electronic components on the circuit board in place of the relay circuit board and connector.
  • additional electronic components can be mounted adjacent insulating housing 5 on the circuit board to allow for increased density of component mounting on the circuit board.
  • connection tails 8 of pin terminals 6 of card connector section 3 and engagement tails 22a of signal terminals 22 of counter connector section 2 make contact in a minimal space at the rear side of insulating housing 5 of card connector section 3 and the front side of insulating housing 21 of counter connector section 4, thus contributing to the reduction of the longitudinal size of the card connector.
  • a card connector 102 has pin terminals 106 arranged in-line at one level, thus forming a single lateral array of pin terminals 106. More specifically, card connector section 103 has a single array of upper and lower rows of pin terminals 106 mounted in its insulating housing 105, and their connection tails 108 extend to the rear side of insulating housing 105. No ground terminals are used in this embodiment.
  • Signal terminals 122 are aixangei at the same interval as connection tails 108 of pin terminals 106, and are mounted in insulating housing 121 of counter connector section 104 with their engagement tails 122a extending from the front of insulating housing 121 and with their solder tails 122b extending forward along a lower surface of insulating housing 121.
  • pin terminals 106 and confronting signal terminals 122 again make contact in a minimal space, permitting the reduction of the longitudinal size of card connector 102. Also, solder tails 122b to be soldered to the signal conveying circuit of the circuit board remain within the area in which insulating housing 105 of card connector section 102 and insulating housing 121 of the counter connector section are mated.

Abstract

Ce connecteur de carte perfectionné (2), servant à recevoir au moins deux cartes de circuit imprimé (1), comprend une section de connexion de carte (3) et une contre section de connexion (4). La section (3) comporte un boîtier isolant doté de deux groupes latéraux (7) de bornes à broches (6) à introduire dans les réceptacles correspondants des cartes, ainsi que de bornes de mise à la masse (9) destinées à entrer en contact avec le boîtier extérieur des cartes. Les groupes latéraux de bornes à broches sont agencés verticalement sur deux niveaux, ou davantage, les bornes de mise à la masse s'étendant au-dessus des agencements latéraux des bornes à broches. La section de connexion comprend encore des tiges (10) de mise à la masse, en forme de «U», traversant verticalement les agencements latéraux de bornes à broches, pour connecter ensemble des bornes adjacentes de mise à la masse. La contre section (4) comprend des bornes de connexion à la masse (23), permettant aux bornes de mise à la masse d'être connectées au circuit de mise à la masse d'une plaquette de circuit sous-jacente, par l'intermédiaire des tiges de bornes de connexion. Cet agencement permet de réduire grandement la dimension longitudinale du connecteur de carte.
