US 5,346,403 A · Connector grounding arrangement

Abstract

A grounding clip (60, FIG. 3 ) is described for mounting in a connector insert (20) to connect the outside of a coaxial contact (26) to a metal shell that surrounds the insert. The clip is formed of a strip of sheet metal with a middle (82) bent into a circle to form a band that closely surrounds and contacts the coaxial contact, the strip having opposite end portions (90, 92) that are each bent in a reverse curve and extend to the outside of the insert to engage the shell. The forward edge (162, FIG. 5 ) of the band has axiallyextending slits (164), with a sheet metal portion (166) at one side of each slit being bent about an inclined bend line (168) to project radially inwardly towards the axis (84) of the band to provide a small area of high pressure contact with the coaxial contact. The band has slots (180) that form retainer tines (182) which extend forwardly and radially inwardly, to abut a shoulder on a flange (80, FIG. 3 ) of the coaxial contact. The clip end portions (90, 92, FIG. 3 ) which lie outside the insert, each includes an arm (116, 118) that extends rearwardly and that has a rearward end (120, 122) that is bent to lie on a rearwardly-facing shoulder (126) of the insert. The connector includes a holdown plate (36, 38, FIG. 2 ) which is fastened to the shell (16), and when so fastened presses firmly against the arm ends (120, 122) to provide an area of high pressure contact between the clip and the shell.

Dependent claims

A connector which includes a conductive shell having a cavity, a dielectric insert lying in said shell cavity and having sides at the outside of the insert and having forward and rearward ends and having a passage extending between its ends with the passage having a passage axis, a grounded contact which lies in said insert passage and which has a grounded outer surface and which has a rear end for connection to a cable having a grounded part, and a clip which is formed of sheet metal and which has a band part that lies around and in engagement with said contact and which has an outside part which extends to the outside of said insert and engages said shell, characterized by:

said band part is bent in substantially a circle about said axis with the thickness dimension of said sheet metal extending radial to said axis, and said band has forward and rearward edges, and said band has a plurality of slits at a first of said edges, with a sheet metal portion at one side of each slit being bent to form a location that is positioned substantially along a side of the slit so said location lies closer to said axis than adjacent parts of said band and so said location contacts said grounded contact.

A connector which includes a conductive shell having a cavity, a dielectric insert lying in said shell cavity and having sides at the outside of said insert, said insert having forward and rearward ends and having a passage extending between its ends with said passage having a passage axis, a grounded contact which lies in said insert passage and which has a grounded outer surface and which has a rear end for connection to a cable having a grounded part, and a sheet metal clip which has a band portion that has opposite ends and that is bent substantially in a circle about said passage axis with the thickness dimension of said sheet metal extending radial to said axis, with said band portion lying around and engaging said contact and with said clip having an outside portion which extends outside said passage to the outside of said insert and engages the walls of said shell cavity, characterized by:

a holdown plate which is fastened to one of said ends of said shell at a location adjacent to a first of said sides of said insert;
said insert having a generally axially facing shoulder at said first side thereof, said outside portion of said clip having an arm which has an arm end that lies against said shoulder, and said holdown plate presses axially against said arm end;
said clip outside portion including inner parts that each extends from one of said band portion ends, with said inner parts each bent about an axis extending parallel to said passage axis to lie beyond said circle and extend largely away from each other, and said clip outside portion including outer .parts extending from said inner parts and lying largely in a common plane and forming arm devices, with a first of said arm devices forming said arm.
