Abstract:
An electrical terminal structure is disclosed which is provided with a flow deposited quantity or band of solder adhered to a selected portion of the terminal and limited from spreading over the surface of the terminal by the presence of a soldernonwettable material adjacent to but not necessarily touching the terminal. A method of mounting the banded electrical terminals in plated apertures provided in a substrate is also disclosed, wherein the solder bands are applied to the terminals according to the above mentioned application technique. A technique of flattening the solder bands, and the resulting terminal structures having flattened solder bands adhered thereto are also disclosed. Flattening of the solder bands facilitates insertion of the banded terminals into the plated apertures by changing the shape of the solder bands and by reducing their structural integrity though the creation of numerous hairline fractures.
Abstract:
A unitary post and receptacle having at least one depending post and spaced longitudinal spring legs. The end portions of the legs are laterally flared and one of the legs is provided with spaced sidewall portions which are parallel or laterally flared. Together, the flared spring legs and sidewall portions define a tapered receptacle extending between the legs. A tab on one of the sidewall portions partially overlies one of the legs.
Abstract:
A low profile contact means stamped from a section of flat stock material and comprising an incomplete cylindrical portion having a C-shaped cross-sectional configuration and further having a flanged portion at one end thereof. A terminal pin extends from the other end of said cylindrical portion. The contact is inserted through an aperture in a printed circuit board with the flanged portion seated on the surface of said circuit board. A tang formed from the cylinder wall extends downwardly into said cylindrical section and towards the gap created by the incomplete cylindrical section. A male pin inserted in said cylindrical section will be pressed by said tang into said gap in said cylindrical section and against the wall of the printed circuit board aperture.
Abstract:
An electrically conducting spring receptacle contained within a cup forms a miniature electrically connecting device in the form of a socket receptacle adapted for mounting within a printed circuit board. A particular feature resides in the socket receptacle fabricated in depending relationship from a carrier strip together with a plurality of similar socket receptacles. These socket receptacles are spaced along a carrier strip in correspondence with the spaces between the corresponding apertures provided in the printed circuit board. The socket receptacles are thereby adapted for simultaneous insertion and mounting within corresponding apertures of the printed circuit board prior to severing the carrier strip from the inserted socket receptacle.
