Abstract

A multiple pin connector includes a printed circuit board positioned between insulating components of a connector insert. The printed circuit board electrically connects together contacts of the connector and is affixed to the insulating components by a bonding material. The contacts pass through the insert and are soldered to traces on the circuit board to thereby group circuits at a first end of the connector into fewer circuits at an opposite end of the connector.

Claims

1. A connector for electrically connecting a first electrical component to a second electrical component, comprising:

contact means including a plurality of socket/pin contacts for carrying electrical signals between said first electrical component and said second electrical component;

means for grouping circuits at a first end of said connector into fewer circuits at an opposite end, including a circuit board having a plurality of holes equal in number to the number of said socket/pin contacts, said circuit board having on at least one surface a plurality of continuous conductive traces connecting together at least two, but less than the total number, of said holes in said circuit board, said socket/pin contacts extending through said holes;

means for electrically connecting said socket/pin contacts to said traces;

connector shell means for housing said circuit board and said socket/pin contacts; and

means including at least one dielectric insert bonded to said circuit board to form an integral assembly for retaining said circuit board and said socket/pin contacts in said shell means.

2. A connector as claimed in claim 1, further comprising means including an environmental seal positioned between said shell means and said dielectric insert for environmentally sealing interior components of said connector.

3. A connector as claimed in claim 1, wherein said at least one dielectric insert comprises two dielectric inserts which sandwich said board and are secured thereto by an adhesive.

4. A connector as claimed in claim 1, wherein said traces comprise conductive material deposited directly on said circuit board.

5. A connector as claimed in claim 1, wherein said traces comprise conductive foil adhered to said circuit board.

6. A connector as claimed in claim 1, wherein said socket/pin contacts comprise a plurality of mating contact halves, including means permitting coupling of said mating contact halves with corresponding contacts in said first electrical component.

7. A connector as claimed in claim 6, wherein said socket/pin contacts further comprise a plurality of rear contact halves including means for electrically connecting said rear contact halves to wires of an electrical cable.

8. A connector as claimed in claim 1, wherein said socket/pin contacts comprise a plurality of rear contact halves including means for electrically connecting said rear contact halves to wires of an electrical cable.

9. A connector as claimed in claim 8, wherein said at least one dielectric insert comprises two dielectric inserts, each having a plurality of passages extending therethrough at positions corresponding to positions of said holes in said circuit board, said dielectric inserts sandwiching said circuit board, said mating contact halves being positioned in the passages in a first one of said dielectric inserts and including extensions which pass through said holes in said circuit board and engage said rear contact halves which are positioned in passages in a second one of said dielectric inserts.

10. A connector as claimed in claim 9, wherein one of said dielelectric inserts includes resilient retaining means for retaining said socket/pin contacts in said connector.

11. A connector as claimed in claim 9, wherein one of said dielectric inserts are secured to said circuit board by an adhesive.

12. A connector as claimed in claim 11, wherein said rear contact halves each includes an annular shoulder extending therefrom which engages said resilient members to retain said rear contact halves in said connector.

13. A connector as claimed in claim 1, further comprising means including a grommet positioned at said opposite end of said connector for environmentally sealing said connector against infiltration of contaminants through said opposite end of said connector.

14. A connector as claimed in claim 13, wherein said socket/pin contacts comprise a plurality of rear contact halves including means for electrically connecting said rear contact halves to wires of an electrical cable, said wires extending through passages in said grommet.

15. A connector as claimed in claim 1, wherein said shell means is cylindrical and said circuit board is circular.

16. A connector as claimed in claim 15, wherein said plurality of holes consists of 128 holes.

17. A connector as claimed in claim 1, wherein said means for electrically connecting said contact pins to said circuit board comprises solder fillets which form solder joints between said traces and said contacts.

18. A connector as claimed in claim 17, wherein said at least one dielectric insert comprises two dielectric inserts which sandwich said board and are secured thereto by an adhesive which surrounds said solder fillets to protect the solder joints from overstress and also to protect said circuit board traces.
