Abstract
Abstract An electrical connector comprises an insulative housing, a shell, a number of terminals received in the housing and grounding means attached to the shell and engaging means. The housing comprises a mating surface with a number of terminal receiving passageways defined therein and an adjacent mounting surface perpendicular to the mating surface. One end of each terminal is received in the corresponding passageway of the housing and the other end is bent to extend through the mounting surface for connecting with a circuit board. The grounding means attached to the shell comprises at least a resilient spring finger appropriately bent and warped relative to the mating surface. After the circuit board is assembled within a computer with the connector mounted thereon extending through a corresponding slot formed in a computer panel, the spring finger of the grounding means reliably contacts an inner surface of the computer panel to establish a grounding path thereby eliminating interference caused by static electricity and ensuring stable signal transmission between the connector and a mating connector.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
253 words
An electrical connector mounted to a circuit board for connecting a mating connector to the circuit board through a corresponding slot disposed in a computer panel, comprising: an insulative housing comprising a mating surface, a mating portion projecting from the mating surface to extend through the slot of the computer panel, a plurality of terminal receiving passageways through the mating portion, and a mounting surface perpendicular to the mating surface; a metal shell abutting against the mating surface of the housing, the metal shell having a shroud enclosing the mating portion of the housing; a plurality of terminals each having one end received in corresponding passageway of the housing and having the other end bent perpendicularly to extend through the mounting surface of the housing for connecting to the circuit board; and grounding means in electrical connection with the metal shell and comprising at least one spring finger resiliently bent to contact an inner surface of the computer panel; wherein the grounding means comprises a metal sheet having an opening for entrance of the shroud of the shell, and two spring fingers are integrally formed on two opposite ends of a bottom edge of the metal sheet; wherein the metal sheet comprises a pair of apertures disposed in opposite ends thereof for extension of screw locks therethrough; wherein the mating surface of the housing comprises a pair of through holes disposed in opposite ends thereof for extension of the screw locks therethrough thereby fastening the grounding means, the shell and the housing together.
Claim 2
Dependent Claim
253 words
An electrical connector mounted to a circuit board for connecting a mating connector to the circuit board through a corresponding slot disposed in a computer panel, comprising: an insulative housing comprising a mating surface, a mating portion projecting from the mating surface to extend through the slot of the computer panel, a plurality of terminal receiving passageways through the mating portion, and a mounting surface perpendicular to the mating surface; a metal shell abutting against the mating surface of the housing, the metal shell having a shroud enclosing the mating portion of the housing; a plurality of terminals each having one end received in corresponding passageway of the housing and having the other end bent perpendicularly to extend through the mounting surface of the housing for connecting to the circuit board; and grounding means in electrical connection with the metal shell and comprising at least one spring finger resiliently bent to contact an inner surface of the computer panel; wherein the grounding means comprises a metal sheet having an opening for entrance of the shroud of the shell, and two spring fingers are integrally formed on two opposite ends of a bottom edge of the metal sheet; wherein the metal sheet comprises a pair of apertures disposed in opposite ends thereof for extension of screw locks therethrough; wherein the mating surface of the housing comprises a pair of through holes disposed in opposite ends thereof for extension of the screw locks therethrough thereby fastening the grounding means, the shell and the housing together.
Claim 3
Dependent Claim
181 words
An electrical connector mounted to a circuit board for connecting a mating connector to the circuit board through a corresponding slot disposed in a computer panel, comprising: an insulative housing comprising a mating surface, a mating portion projecting from the mating surface to extend through the slot of the computer panel; a plurality of terminals received within the housing; a metal shell abutting against the mating surface of the housing, the metal shell having a shroud enclosing the mating portion of the housing; and grounding means mechanically and electrically connected to the metal shell and comprising at least one spring finger resiliently bent to contact an inner surface of the computer panel; wherein said grounding means defines an opening surrounding the shroud of the shell; wherein said grounding means is fastened to the shell by a screw lock, and wherein said screw lock cooperates with a clinch nut to fasten the shell, the housing, the grounding means, and a board lock together; wherein said grounding means has two spring fingers integrally formed on two opposite ends of a bottom edge thereof.
