Connector for a leadless electronic package

Claim 2

A connector for an electronic package of the type having spaced conductive pads on tabs projecting outwardly from two opposing sides, said connector comprising: a. a frame-shaped housing having four spaced apart walls joined at the ends thereof to define the frame-shape and further to define a central opening therebetween with the distance between two opposing walls being approximately equal to the dimension of the electronic package between the outwardly projecting tabs, further, said two opposing walls having terminal-receiving cavities spaced along therein, said cavities having a vertical slot located in the lower portion of the walls and opening downwardly therefrom, said housing being of an insulating material; and b. a number of conductive terminals having a circular contact section and connecting means extending from and adapted for connecting the circular contact section to a printed circuit board, said terminals being positioned in the cavities with the circular contact sections being in the vertical slots and extending downwardly therefrom so that upon an electronic package being inserted into the central opening from below, the circular contact sections contact the pads on the tabs which extend below the two opposing walls.

Claim 3

The connector of claim 1 wherein said terminal-receiving cavities have a vertical shaft behind and in communication with the vertical slot and the connecting means on the terminals including a vertical section connected to and located behind the circular contact section and in the same vertical plane therewith, said vertical sections being received in the vertical shafts of said cavities with a lower part of the vertical section extending below the housing for insertion into a hole in a printed circuit board.

Claim 4

The connector of claim 2 further including probe openings extending into the two opposing walls and intersecting the cavities, said probe openings providing an upwardly facing floor positioned normal and open to the vertical shafts, said terminals further having a lance struck from and attached to the vertical section, said lance extending obliquely downwardly so that upon positioning a terminal in a cavity, said lance abuts the floor and prevents withdrawal of the terminal.

Claim 5

The connector of claim 2 wherein the lower part of the vertical section of the terminals include a jog for retaining the terminals in holes in a printed circuit board.

Claim 6

A method of making the terminals of the connector of claim 2 which comprises the steps of: a. stamping out from flat stock a predetermined shape comprising a contact section and a vertical section; b. bending the contact section ninety degrees so that it extends perpendicular to the vertical section; and c. curving the end of the contact section down and back around 360 degrees forming the circular contact section which is in front of and lies in the same plane as the vertical section.

Claim 7

A connector for an electronic package of the type having spaced conductive pads on tabs projecting outwardly from two opposing sides, said connector comprising: a. a frame-shaped housing having four spaced apart walls joined at the ends thereof to define the frame-shape and further to define a central opening therebetween with the distance between two opposing walls being approximately equal to the dimension of the electronic package between the outwardly projecting tabs, further, said two opposing walls having terminal-receiving cavities spaced along therein, said cavities having a vertical shaft and a connecting vertical slot, said slot being in the lower, inside portion of the walls and opening downwardly therefrom, said housing being of an insulative material; and b. a number of conductive terminals having a vertical section and a circular contact section, the latter section extending forwardly of the vertical section and lying in the same vertical plane therewith, said terminals being positioned in the cavities with the vertical section being in the vertical shaft and extending below the housing for connection to a printed circuit board and the circular contact section being in the vertical slot and extending downwardly therefrom, so that upon the electronic package being inserted into the central opening from below, the circular contact sections contact the pads on the tabs which underlie the two opposing walls.

Claim 8

A connector for an electronic package of the type having spaced conductive pads on tabs projecting outwardly from two opposing sides, said connector comprising: a. a frame-shaped housing having four spaced apart walls joined at the ends thereof to define the frame-shape and further to define a central opening therebetween with the distance between two opposing walls being approximately equal to the dimension of the electronic package between the outwardly projecting tabs, further, said two opposing walls having terminal-receiving cavities spaced along therein, said cavities having a vertical shaft and a connecting vertical slot, said slot being in the lower, inside portion of the walls and opening downwardly therefrom, said housing being of an insulative material; and b. a number of conductive terminals having a vertical section and a circular contact section, the latter section extending forwardly of the vertical section and lying in the same vertical plane therewith, said terminals being positioned in the cavities with the vertical section being in the vertical shaft and extending below the housing for connection to a printed circuit board and the circular contact section being in the vertical slot and extending downwardly therefrom, so that upon the electronic package being inserted into the central opening from below, the circular contact sections contact the pads on the tabs which underlie the two opposing walls.

Claim 9

A method of making the terminals of the connector of claim 6 which comprises the steps of: a. stamping out an elongated strip of predetermined shape from flat stock; b. bending an upper portion of the strip ninety degrees so it extends normally to the lower portion; and c. curving the end of the upper portion down and back around forming the circular contact section.

Claim 10

The connector of claims 1, 2, 3, 4 or 6 further including means for retaining the electronic package in the central opening of the housing.

Claim 11

The connector of claim 8 wherein the means includes a flat plate having a central opening of the same dimensions as the central opening in the connector housings and a support bar of insulative material on each of the two opposing sides of the central opening and means for attaching the plate to the connector housing so that the support bars bear against the underside of the tabs on the electronic package.
