Abstract
A contact assembly comprised of two parts bonded (e.g., welded) together, the first part including a male pin portion and the second part including a cylindrical jacket terminating in a flat end surface adapted for being electrically coupled (e.g., soldered) to a conductor (e.g., pad) on a substrate (e.g., PCB). Several contact assemblies may be positioned within a housing or substrate, to form a connector assembly which may then be positioned on and electrically coupled to a second substrate (e.g., a PCB), forming an electronic assembly.
Claims13
An electron assembly comprising:
- a first substrate;
- a second substrate with an electrical pad on a surface of said second substrate;
- a connector assembly comprising:
- a first contact having a first sleeve portion secured within a hole in said first substrate, said first contact having a pin portion integral with said first sleeve portion and protruding from said first sleeve portion external to said first substrate, said pin portion being designed to insert in a hole in a printed circuit board;
- a second contact having a second sleeve portion and an end portion integral with said sleeve portion, said pin portion being soldered or welded within said second sleeve portion, said end portion having a flat surface in a plane perpendicular to said pin portion and a tapered perimeter region around said flat surface leading outwardly to said second sleeve portion, said end portion being surface-mount soldered to said electrical pad on said surface of said second substrate, and wherein said second contact is free standing other than its soldered or welded connection to said pin portion and its solder connection to said electrical pad.
An electronic assembly comprising:
- a first substrate;
- a second substrate with an electrical pad on a surface of said second substrate;
- a connector assembly comprising:
- a first contact having a first sleeve portion secured within a hole in said first substrate, said first contact having a pin portion integral with said first sleeve portion and protruding from said first sleeve portion external to said first substrate;
- and
- a second contact having a second sleeve portion and an end portion integral with said sleeve portion, said pin portion being soldered or welded within said second sleeve portion, said end portion having a flat surface in a plane perpendicular to said pin portion and a tapered perimeter region around said flat surface leading outwardly to said second sleeve portion, said end portion being surface-mount soldered to said electrical pad on said surface of said second substrate, and wherein said second contact is free standing other than its soldered or welded connection to said pin portion and its solder connection to said electrical pad.
