Abstract
Abstract A die cast metal shell for an electrical connector is made up of a base and cover. Cable braid deforming teeth are die cast into a cable entry passage at the rear of the shell, and a thin wall front shield is integrally die cast with the base to provide a low resistance path between the cable braid and the front shield. A circuit board may be positioned in a backshell portion of the base, the circuit board including traces to which wires of the cable are terminated and extending forwardly from the backshell through a relatively narrow front opening to form a set of contacts for the connector.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
218 words
A die cast metal connector shell, comprising: a backshell consisting of a base and a cover, said base consisting of a single seamless die cast base member including a bottom wall, a front wall, a rear portion, two side walls, and a front shield integrally formed from said base and extending from said front wall, wherein said base and cover together form a substantially enclosed chamber in which wires of a cable are connected to a set of electrical contacts, wherein said front wall forms a front wall of said chamber and includes an opening through which said set of electrical contacts exits said chamber, wherein said rear portion forms a rear wall of said chamber and includes an interior rear section which defines an interior arc-shaped passage section through which the cable enters the chamber; and wherein the front shield includes a shield wall having a trapezoidal shape, the shield wall extending forwardly from said front wall of said base, wherein the shield wall is thin relative to the front wall of the base, and surrounds said set of electrical contacts extending forwardly from said chamber through said opening in said front wall, and whereby said shield wall is integrally formed from said base to provide continuous shielding from said arc-shaped passage section to said front shield.
Claim 2
Dependent Claim
218 words
A die cast metal connector shell, comprising: a backshell consisting of a base and a cover, said base consisting of a single seamless die cast base member including a bottom wall, a front wall, a rear portion, two side walls, and a front shield integrally formed from said base and extending from said front wall, wherein said base and cover together form a substantially enclosed chamber in which wires of a cable are connected to a set of electrical contacts, wherein said front wall forms a front wall of said chamber and includes an opening through which said set of electrical contacts exits said chamber, wherein said rear portion forms a rear wall of said chamber and includes an interior rear section which defines an interior arc-shaped passage section through which the cable enters the chamber; and wherein the front shield includes a shield wall having a trapezoidal shape, the shield wall extending forwardly from said front wall of said base, wherein the shield wall is thin relative to the front wall of the base, and surrounds said set of electrical contacts extending forwardly from said chamber through said opening in said front wall, and whereby said shield wall is integrally formed from said base to provide continuous shielding from said arc-shaped passage section to said front shield.
Claim 3
Dependent Claim
50 words
A metal shell as claimed in claim 1, wherein said base further includes posts die cast into the base for supporting a circuit board, wherein said set of contacts is formed on the circuit board, and wherein said circuit board extends from the chamber through said opening into the shield.
Claim 4
Dependent Claim
25 words
A metal shell as claimed in claim 2, wherein said opening includes notches formed at edges of the opening to further support said circuit board.
Claim 5
Dependent Claim
14 words
A connector shell as claimed in claim 1, wherein said front shield is D-shaped.
Claim 6
Dependent Claim
233 words
An electrical connector, comprising: a metal shell; and a circuit board positioned in the metal shell, wherein the metal shell comprises: a backshell consisting of a base and a cover, said base consisting of a single seamless die cast base member including a bottom wall, a front wall, a rear portion, two side walls, and a front shield integrally formed from said base and extending forwardly from said front wall, wherein said base and cover together form a substantially enclosed chamber in which wires of a cable are terminated to a set of electrical contacts, wherein said front wall forms a front wall of said chamber and includes an opening through which said set of electrical contacts exits said chamber, wherein said rear portion forms a rear wall of said chamber and includes an interior rear section which defines an interior arc-shaped passage section through which the cable enters the chamber; and wherein the front shield includes a shield wall having a trapezoidal shape, the shield wall extending forwardly from said front wall of said base, wherein the shield wall is thin relative to the front wall of the base, and surrounds said set of electrical contacts extending forwardly from said chamber through said opening in said front wall, and whereby said shield wall is integrally formed from said base to provide continuous shielding from said arc-shaped passage section to said front shield.
Claim 7
Dependent Claim
233 words
An electrical connector, comprising: a metal shell; and a circuit board positioned in the metal shell, wherein the metal shell comprises: a backshell consisting of a base and a cover, said base consisting of a single seamless die cast base member including a bottom wall, a front wall, a rear portion, two side walls, and a front shield integrally formed from said base and extending forwardly from said front wall, wherein said base and cover together form a substantially enclosed chamber in which wires of a cable are terminated to a set of electrical contacts, wherein said front wall forms a front wall of said chamber and includes an opening through which said set of electrical contacts exits said chamber, wherein said rear portion forms a rear wall of said chamber and includes an interior rear section which defines an interior arc-shaped passage section through which the cable enters the chamber; and wherein the front shield includes a shield wall having a trapezoidal shape, the shield wall extending forwardly from said front wall of said base, wherein the shield wall is thin relative to the front wall of the base, and surrounds said set of electrical contacts extending forwardly from said chamber through said opening in said front wall, and whereby said shield wall is integrally formed from said base to provide continuous shielding from said arc-shaped passage section to said front shield.
Claim 8
Dependent Claim
50 words
A metal shell as claimed in claim 5, wherein said base further includes posts die cast into the base for supporting a circuit board, wherein said set of contacts is formed on the circuit board, and wherein said circuit board extends from the chamber through said opening into the shield.
Claim 9
Dependent Claim
24 words
A connector as claimed in claim 6, wherein said opening includes notches formed at edges of the opening to further support said circuit board.
Claim 10
Dependent Claim
57 words
A connector as claimed in claim 5, wherein said cover is generally planar and wherein a portion of said cover which defines an upper surface of the entry passage for the cable into the chamber is formed by a raised portion of said cover so that a thickness of a front portion of the backshell is minimized.
Claim 11
Dependent Claim
14 words
An electrical connector as claimed in claim 5, wherein said front shield is D-shaped.
