- 4. The card connector described in claim 1 wherein:
- a plurality of said contact legs are each formed from a metal sheet, with most of each contact leg being of uniform width along an imaginary centerline of the leg, but with each contact leg including a forward portion having an enlargement containing said contact location with the enlargement being of greater width than the rest of the contact leg, and with said forward portion being twisted 90.degree. about said centerline.
- 5. The connector described in claim 1 wherein:
- said pair of interception plates comprise portions of an interceptor that includes a bridge connecting said plates and integral with them, said bridge having a mounted part projecting into a hole in said support.
- 6. A card connector for receiving and connecting to the conductive pads of traces of a circuit board card of predetermined thickness which has traces on its opposite faces and which has a leading edge, comprising:
- a housing which includes a support of insulative material;
- first and second rows of contacts with rearward portions held in said support and with said rows of contacts being spaced apart to receive said card between them, and each of said contacts having a contact location where it engages one of said traces on said card;

- 7. The card connector described in claim 6 wherein:
- the pads on each face of said card alternate in distance from said card leading edge, with a first group of pads spaced a first distance from said edge and a second group of pads spaced a larger second distance from said edge;
- a second plurality of said contacts are each formed of a metal sheet with a contact leg extending forwardly and having a greater first width in a direction along the corresponding row than its thickness perpendicular to the row, each contact leg having an outer portion with a region of greater thickness than said first width but said outer portion twisted by 90.degree. about the length of said first portion and with said region having said contact location, said region located so said contact location can engage a pad at said second distance from said card edge.
- 8. A connector for connecting first and second circuit boards lying in perpendicular planes, comprising:
- an insulative housing forming a support lying on said first circuit board and forming a space for receiving the second board at a final position;
- first and second rows of contacts lying on opposite sides of said second board final position, each contact having a mounted part mounted in said support and in the first circuit board, and each contact having a strip-shaped leg extending in a forward direction away from said support, the legs of the contacts in each row being spaced apart along the row and the legs of the contacts in said first and second rows having outer faces furthest from said second board final position, and the outer leg faces of the contacts in said first and second rows lying respectively in first and second imaginary planes;
- first and second interception plates, each having a predetermined potential, said plates having inner faces facing said contact leg outer faces, said plate inner faces lying in planes that are parallel respectively to said first and second planes;
- the inner face of each interception plate lying a distance from corresponding contact leg outer faces which is less than the spacing of said legs along the row, and each plate extending along most of the height of the corresponding contact legs;
- the space between the contacts of each row and an adjacent interception plate being substantially devoid of insulation, and said housing forming a stop that abuts a forward location of each contact leg to limit its movement toward a corresponding interception plate to a contact position wherein the contact leg extends parallel to the corresponding plate.
- 9. The connector described in claim 8 wherein:
- said first and second interception plates are parts of an interceptor that includes a pair of bridges lying against said support and connecting said plates, said interceptor including at least one pin extending through said support into said first circuit board.
- 10. A connector comprising:
- insulative support means;
- a row of contacts with each contact including a mounted part in said support means and an elongated leg extending primarily in a predetermined forward direction from said mounted part, with the legs of the contacts in said row lying substantially in an imaginary plane;
- an interception plate of electrically conductive material lying in a plane extending parallel to said imaginary plane of said row, said interception plate lying closer to the contacts of said row of contacts than the distance between said contacts in said row, and said interception plate having at least a portion adjacent to a plurality of said contacts and at a predetermined potential; and
