Abstract
Abstract A seamless one-piece shield is provided for an electrical connector to prevent electromagnetic leakage. The connector includes a dielectric housing, with the shield substantially surrounding the housing. The shield is stamped and formed from sheet metal material and includes a base wall integrally joined to a pair of opposite side walls and a pair of opposite end walls, defining a generally box-like structure having an open side at a mating side of the connector housing opposite the base wall of the shield. The shield is void of any open seams and includes flap portions integrally joining the side walls to the end walls of the shield. Each flap portion is disposed in a folded condition against one of the side walls or the end walls of the shield.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
122 words
In a one-piece shield for an electrical connector which includes a dielectric housing with the shield substantially surrounding the housing, the shield being stamped and formed from sheet metal material and including a base wall integrally joined to a pair of opposite side walls and a pair of opposite end walls defining a generally box-like structure having an open side at a mating side of the connector housing opposite the base wall of the shield, wherein the improvement comprises said shield being void of open seams and including flap portions integrally joining the side walls to the end walls of the shield and each flap portion being disposed in a folded condition against one of the side walls and the end walls.
Claim 2
Dependent Claim
122 words
In a one-piece shield for an electrical connector which includes a dielectric housing with the shield substantially surrounding the housing, the shield being stamped and formed from sheet metal material and including a base wall integrally joined to a pair of opposite side walls and a pair of opposite end walls defining a generally box-like structure having an open side at a mating side of the connector housing opposite the base wall of the shield, wherein the improvement comprises said shield being void of open seams and including flap portions integrally joining the side walls to the end walls of the shield and each flap portion being disposed in a folded condition against one of the side walls and the end walls.
Claim 3
Dependent Claim
54 words
In a one-piece shield as set forth in claim 1, wherein said flap portions each comprise a pair of juxtaposed triangular portions integrally joined to each other at a fold line and each triangular portion being integrally joined to a respective one of an adjacent side wall and end wall at a fold line.
Claim 4
Dependent Claim
26 words
In a one-piece shield as set forth in claim 2, wherein said flap portions are disposed in folded positions against the side walls of the shield.
Claim 5
Dependent Claim
85 words
In a one-piece shield for at least partially surrounding a dielectric housing of an electrical connector, the shield being stamped and formed from metal material and including a base wall, at least one side wall and at least one end wall integrally joined to the base wall, wherein the improvement comprises a flap portion integrally joining the side wall and the end wall and being disposed in a folded condition in juxtaposition to one of the side wall and the end wall of the shield.
Claim 6
Dependent Claim
85 words
In a one-piece shield for at least partially surrounding a dielectric housing of an electrical connector, the shield being stamped and formed from metal material and including a base wall, at least one side wall and at least one end wall integrally joined to the base wall, wherein the improvement comprises a flap portion integrally joining the side wall and the end wall and being disposed in a folded condition in juxtaposition to one of the side wall and the end wall of the shield.
Claim 7
Dependent Claim
50 words
In a one-piece shield as set forth in claim 4, wherein said flap portion comprises a pair of overlapped triangular portions integrally joined to each other at a fold line and each triangular portion being integrally joined to one of the side wall and the end wall of the shield.
Claim 8
Independent Claim
162 words
A method of forming a one-piece shield from sheet metal material such that the shield forms a box-like structure with a generally rectangular base wall integrally joined to a pair of generally rectangular opposite side walls and a pair of generally rectangular end walls for substantially surrounding a dielectric housing of an electrical connector, comprising the steps of: stamping a generally rectangularly shaped blank from the sheet metal material; folding side sections and end sections of the blank relative to a central section of the blank along respective fold lines to define the side walls, end walls and base wall, respectively, of the shield; and folding corner sections of the blank relative to the side sections, end sections and base section along fold lines to define flap portions integrally joining the side walls to the end walls of the shield and to dispose the flap portions in juxtaposition to respective ones of the side walls and the end walls of the shield.
Claim 9
Independent Claim
162 words
A method of forming a one-piece shield from sheet metal material such that the shield forms a box-like structure with a generally rectangular base wall integrally joined to a pair of generally rectangular opposite side walls and a pair of generally rectangular end walls for substantially surrounding a dielectric housing of an electrical connector, comprising the steps of: stamping a generally rectangularly shaped blank from the sheet metal material; folding side sections and end sections of the blank relative to a central section of the blank along respective fold lines to define the side walls, end walls and base wall, respectively, of the shield; and folding corner sections of the blank relative to the side sections, end sections and base section along fold lines to define flap portions integrally joining the side walls to the end walls of the shield and to dispose the flap portions in juxtaposition to respective ones of the side walls and the end walls of the shield.
Claim 10
Dependent Claim
27 words
The method of claim 6 wherein said side sections, end sections and corner sections all are folded relative to the center section of the blank substantially continuously.
Claim 11
Dependent Claim
32 words
The method of claim 6 wherein said corner sections are generally rectangular and each corner section is folded along a fold line bisecting the corner section into a pair of triangular portions.
Claim 12
Independent Claim
152 words
A method of forming a one-piece shield from sheet metal material such that the shield includes at least one side wall and at least one end wall integrally joined to a base wall, comprising the steps of: providing a blank of the sheet metal material of a size and configuration to define said side wall, end wall and base wall; folding a side section and an end section of the blank relative to an intermediate section of the blank along respective fold lines to define the side wall, end wall and base wall, respectively, of the shield; and folding a corner section of the blank relative to the side section, end section and intermediate section to define flap portions integrally joining the side wall and the end wall of the shield and to dispose the flap portion in juxtaposition to one of the end wall and the side wall of the shield.
Claim 13
Independent Claim
152 words
A method of forming a one-piece shield from sheet metal material such that the shield includes at least one side wall and at least one end wall integrally joined to a base wall, comprising the steps of: providing a blank of the sheet metal material of a size and configuration to define said side wall, end wall and base wall; folding a side section and an end section of the blank relative to an intermediate section of the blank along respective fold lines to define the side wall, end wall and base wall, respectively, of the shield; and folding a corner section of the blank relative to the side section, end section and intermediate section to define flap portions integrally joining the side wall and the end wall of the shield and to dispose the flap portion in juxtaposition to one of the end wall and the side wall of the shield.
Claim 14
Dependent Claim
20 words
The method of claim 9 wherein said corner section is folded along a fold line generally bisecting the corner section.
