Surface Solder Harcon Connector

      Disclosed is a bifurcated spring connector that can be surface
soldered to a circuit board.

      Presently this type of connector exists as a soldered pin in
hole connector.  There is a need to have a bifurcated spring
connector on the opposite side of the circuit board, but board real
estate limits the design of more PTH's.  This dictates the use of a
surface soldered connector that can use the existing soldered PTH's.

      Figure 1 shows us a surface mounting type harcon connector.
Instead of a long tail which is placed into a PTH, a round base at
the bottom of the tail is fixtured and soldered to the surface of the
PTH.  The hole in the base allows solder to flow up and over the base
to form the bond. Figure 2 shows a cross-section of a surface
soldered harcon. Here one can see how the solder flows up the hole in
the base to form a bond.  Figure 3 shows us that the base diameter is
larger than the bifurcated spring area, allowing easy assembly and
removal of the location fixturing device used in the solder assembly
operation.
