Abstract
A high density connector for connecting to the edge of a printed circuit board uses two different contact terminals, one of which is reversible, and a spacing block to guide the contact terminals into the connector and to maintain close spacing of the contacts on each side of the printed circuit board. The connector housing has openings in the center of the housing to allow for expansion of the housing material and to provide for an optional grounding bus.
Claims12
A multi row connector adapted for electrical connection to contact pads disposed on opposed sides of one edge of a printed circuit board, comprising:
- an insulator having an underside, a central region and first and second sets of contact cavities formed therein in symmetrical disposition about said central region of said insulator, and wherein each of said first and second sets of contact cavities are formed as plural rows of contact cavities in symmetrical disposition about said central region;
- a first and second plurality of contacts disposed in said plural rows of contact cavities of said first and second sets, respectively, and wherein said first and second plurality of contacts include contact ends extending out from said underside of said insulator, said contacts ends of said first and second plurality of contacts adapted for surface mounting to the contact pads disposed on the opposed sides of the one edge of the printed circuit board;
- a first spacing block disposed adjacent said underside of said insulator coacting with said contact ends of said first plurality of contacts to properly space and position said contact ends of said first plurality of contacts in a single row for surface mounting to the contact pads disposed on one side of the one edge of the printed circuit board;
- and
- a second spacing block disposed adjacent said underside of said insulator coacting with said contact ends of said second plurality of contacts to properly space and position said contact ends of said second plurality of contacts in a single row for surface mounting to the contact pads disposed on the opposed side of the one edge of the printed circuit board, and wherein
- said first and second spacing blocks in combination with said insulator form a slot adjacent said underside of said insulator for insertion of the printed circuit board.

A multi row connector adapted for electrical connection to contact pads disposed on opposed sides of one edge of a printed circuit board, comprising;
- an insulator having a central region and a plurality of rows of contact cavities symmetrically disposed about said central region, said insulator further including an underside having a first and second plurality of post-receiving openings formed therein on each side of said central region;
- a first and second spacing block, each of said first and second spacing blocks having a first and second plurality of posts depending therefrom for insertion into respective ones of said first and second plurality of post-receiving openings to dispose said first and second spacing blocks adjacent said underside of said insulator, said first and second spacing blocks in combination forming a slot adjacent said underside of said insulator for insertion of the printed circuit board, and wherein each said first and second spacing blocks has a first and second plurality of grooves formed in a side facing said slot and a third plurality of grooves formed in the side opposed to the side facing said slot;
- a first plurality of contacts disposed in respective rows of said plurality of rows of contact cavities symmetrically about said central region, said first plurality of contacts having contact ends disposed in said third plurality of grooves of said first and second spacing blocks;
- a second plurality of contacts disposed in respective rows of said plurality of rows of contact cavities symmetrically about said central region, said second plurality of contacts having contact ends disposed in said first plurality of grooves of said first and second spacing blocks;
- and
- a third plurality of contacts disposed in respective rows of said plurality of rows of contact cavities symmetrically about said central region, said third plurality of contacts having contact ends disposed in said second plurality of grooves of said first and second spacing blocks;
- and wherein
- said contact ends of said first, second and third plurality of contacts disposed in said third, first and second plurality of grooves of said first and second spacing blocks, respectively, form a single row of contact ends associated with each said first and second spacing blocks for surface mounting to the contact pads disposed on the opposed sides of the one edge of the printed circuit board.
