Abstract
Abstract An electrical connector assembly 2 for use with a printed circuit board 6 includes an electrical connector 4, such as a standard miniature ribbon connector, and an injection molded lead positioning comb 48. Cantilever beams 54 in the lead positioning comb 48 form lead receiving slots 52 into which terminal leads 40 extending at right angles from terminals 26 inserted into a connector housing 8 precisely position rows of leads 40 for insertion into printed circuit board holes or on surface mount pads. The slots 52 on the lead positioning comb 48 face the connector housing 8 and the comb 48 is snapped to the housing from the rear. As the comb is snapped to the housing, the terminal leads enter the slots. Carrier strips 46 join terminals in each row during insertion of the leads into the slots to prevent deflection. The carrier strips 46 are removed after assembly of the comb 48 to the housing 4. Relief slots 55 are formed to permit adjacent beams 54 to deflect during simultaneous insertion of all of the terminal leads. The beams 54 are molded by two mold halves that are retracted perpendicular to the plane of the cantilever beams.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
176 words
An electrical connector assembly for use with a printed circuit board comprising: a housing including a plurality of cavities located in at least one row between opposite housing faces; terminals positioned in the cavities, each terminal extending from a corresponding cavity and then extending at a right angle relative to the corresponding cavity along one face of the housing and including a printed circuit board terminal lead at a distal end; and a lead positioning comb attachable to the housing, the comb including a plurality of side by side slots formed by cantilever beams located in a common plane and extending from a base toward the housing, the slots having respective open ends, facing the housing, through which the terminal leads enter as the comb is moved toward the housing for attachment to the housing, adjacent said cantilever beams defining adjacent said slots being spaced apart by relief slots which permit the adjacent beams to outwardly flex, in the common plane, as side by side terminal leads are simultaneously inserted into the side by side slots.
Claim 2
Dependent Claim
176 words
An electrical connector assembly for use with a printed circuit board comprising: a housing including a plurality of cavities located in at least one row between opposite housing faces; terminals positioned in the cavities, each terminal extending from a corresponding cavity and then extending at a right angle relative to the corresponding cavity along one face of the housing and including a printed circuit board terminal lead at a distal end; and a lead positioning comb attachable to the housing, the comb including a plurality of side by side slots formed by cantilever beams located in a common plane and extending from a base toward the housing, the slots having respective open ends, facing the housing, through which the terminal leads enter as the comb is moved toward the housing for attachment to the housing, adjacent said cantilever beams defining adjacent said slots being spaced apart by relief slots which permit the adjacent beams to outwardly flex, in the common plane, as side by side terminal leads are simultaneously inserted into the side by side slots.
