Electrical connector with mounting post

Claim 2

In an electrical connector adapted for surface mounting on a substrate such as a printed circuit board having a mounting hole of a given diameter, the connector including a dielectric housing having a board-mounting face, and an elongated mounting post projecting from said board-mounting face for insertion into the mounting hole in the substrate, wherein the improvement comprises: said elongated mounting post including a plurality of longitudinally extending, circumferentially spaced, generally rigid ribs defining a circle having a diameter approximately the same as said given diameter of the mounting hole, and a plurality of flexible, longitudinally extending ribs located alternatingly between said generally rigid ribs and defining a circle having a diameter at least slightly greater than said given diameter of the mounting hole.

Claim 3

In an electrical connector as set forth in claim 1, wherein said generally rigid ribs define a circle having a diameter slightly less than said given diameter of the mounting hole.

Claim 4

In an electrical connector as set forth in claim 1, wherein said dielectric housing is molded of plastic material with said mounting post being integral therewith.

Claim 5

In an electrical connector as set forth in claim 1, wherein said flexible ribs have outer peripheral areas extending oblique to the inside surface of the mounting hole to facilitate flexing of the flexible ribs upon insertion into the mounting hole.

Claim 6

In an electrical connector as set forth in claim 1, wherein each of said generally rigid ribs has an outer edge formed on a radius.

Claim 7

In an electrical connector as set forth in claim 1, wherein said mounting post has a distal end that is chamfered to facilitate guiding the mounting post into the mounting hole.

Claim 8

An electrical connector adapted for surface mounting on a substrate such as a printed circuit board having a mounting hole of a given diameter, comprising: a dielectric housing unitarily molded of plastic material and having a board-mounting face; an elongated mounting post integral with the housing and projecting from said board-mounting face for insertion into the mounting hole in the substrate; a plurality of longitudinally extending, circumferentially spaced, generally rigid ribs projecting radially of the elongated mounting post, each rib having an outer edge formed on a radius, and the combined outer edges of the ribs defining a circle having a diameter approximately equal to said given diameter of the mounting hole; and a plurality of flexible, longitudinally extending ribs located alternatingly between said generally rigid ribs and defining a circle having a diameter at least slightly greater than said given diameter of the mounting hole, the flexible ribs having outer peripheral areas extending oblique to the inside surface of the mounting hole to facilitate flexing of the flexible ribs upon insertion into the mounting hole.

Claim 9

An electrical connector adapted for surface mounting on a substrate such as a printed circuit board having a mounting hole of a given diameter, comprising: a dielectric housing unitarily molded of plastic material and having a board-mounting face; an elongated mounting post integral with the housing and projecting from said board-mounting face for insertion into the mounting hole in the substrate; a plurality of longitudinally extending, circumferentially spaced, generally rigid ribs projecting radially of the elongated mounting post, each rib having an outer edge formed on a radius, and the combined outer edges of the ribs defining a circle having a diameter approximately equal to said given diameter of the mounting hole; and a plurality of flexible, longitudinally extending ribs located alternatingly between said generally rigid ribs and defining a circle having a diameter at least slightly greater than said given diameter of the mounting hole, the flexible ribs having outer peripheral areas extending oblique to the inside surface of the mounting hole to facilitate flexing of the flexible ribs upon insertion into the mounting hole.

Claim 10

The electrical connector of claim 7 wherein said generally rigid ribs define a circle having a diameter slightly less than said given diameter of the mounting hole.

Claim 11

The electrical connector of claim 7 wherein said flexible ribs are thinner than said generally rigid ribs.

Claim 12

The electrical connector of claim 7 wherein said mounting post has a distal end that is chamfered to facilitate guiding the mounting post into the mounting hole.
