Abstract
Abstract An electromagnetic shield assembly for securing a circuit board having an electromagnetic shield; and an electrically-conductive gasket having a framework of planar limbs and opposing first and second projections upstanding laterally from at least one of the limbs to intimately contact side faces of the shield and inhibit movement of the shield in a direction between the first and second projections, wherein the first projection includes a barb engaging a side face of the shield to fasten the gasket to the shield.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
187 words
An electromagnetic shield assembly comprising a circuit board and a shield, the shield having at least one side wall defined by a pair of side faces each of said side faces defining an exposed edge extending in a given plane, said shield being mounted on the circuit board by means including: a gasket providing electromagnetic sealing therebetween and comprising a planar framework of limbs which extends on the surface of the circuit board in a plane extending parallel to the circuit board and extends parallel to the given plane of the exposed edge of the shield, said planar framework of limbs being disposed between the exposed edge of said shield and the circuit board, the gasket further having opposing first and second projections upstanding from and extending away from said at least one of the limbs in opposite directions therefrom to intimately contact the side faces of the shield and inhibit movement of the shield in a direction between said first and second projections, and said first projection engaging with and piercing one of said side faces of the shield to fasten the gasket to the shield.
Claim 2
Dependent Claim
187 words
An electromagnetic shield assembly comprising a circuit board and a shield, the shield having at least one side wall defined by a pair of side faces each of said side faces defining an exposed edge extending in a given plane, said shield being mounted on the circuit board by means including: a gasket providing electromagnetic sealing therebetween and comprising a planar framework of limbs which extends on the surface of the circuit board in a plane extending parallel to the circuit board and extends parallel to the given plane of the exposed edge of the shield, said planar framework of limbs being disposed between the exposed edge of said shield and the circuit board, the gasket further having opposing first and second projections upstanding from and extending away from said at least one of the limbs in opposite directions therefrom to intimately contact the side faces of the shield and inhibit movement of the shield in a direction between said first and second projections, and said first projection engaging with and piercing one of said side faces of the shield to fasten the gasket to the shield.
Claim 3
Dependent Claim
80 words
An assembly as defined in claim 1 further characterized by said framework of limbs having a first and an opposite second surface, said first surface facing said shield and said second surface facing said circuit board, said first surface being sized and shaped to match the size and shape of said exposed edge of said shield at least one side wall and being placed in confrontation therewith when said first projection engages with and fastens the gasket to the shield.
Claim 4
Dependent Claim
26 words
An assembly as in claim 1, wherein the second projection includes a barb engaging a face of the shield to fasten the gasket to the shield.
Claim 5
Dependent Claim
17 words
As assembly as in claim 1, wherein the barb is made from harder material than the shield.
Claim 6
Dependent Claim
20 words
An assembly as in claim 1, wherein the projections are bent out of a plane which includes an associated limb.
Claim 7
Dependent Claim
10 words
A gasket suitable for the assembly as in claim 1.
Claim 8
Dependent Claim
167 words
An electromagnetic shield assembly for securing a circuit board comprising: an electromagnetic shield, said shield having at least one side wall defined by a pair of side faces each of said side faces defining an exposed edge extending in a given plane; and an electrically-conductive gasket comprising a framework of planar limbs extending on the surface of the circuit board in a plane extending parallel to the circuit board and extending in a plane parallel to said given plane and located between said circuit board and said exposed edge of said shield side wall, first and second integrally formed projections upstanding laterally outwardly in opposite directions away from at least one of the limbs to intimately contact the side faces of the shield and inhibit movement of the shield in a direction between the first and second projections, wherein the first projection includes a barb engaging with and piercing a side face of the shield at least one side wall to fasten the gasket to the shield.
Claim 9
Dependent Claim
167 words
An electromagnetic shield assembly for securing a circuit board comprising: an electromagnetic shield, said shield having at least one side wall defined by a pair of side faces each of said side faces defining an exposed edge extending in a given plane; and an electrically-conductive gasket comprising a framework of planar limbs extending on the surface of the circuit board in a plane extending parallel to the circuit board and extending in a plane parallel to said given plane and located between said circuit board and said exposed edge of said shield side wall, first and second integrally formed projections upstanding laterally outwardly in opposite directions away from at least one of the limbs to intimately contact the side faces of the shield and inhibit movement of the shield in a direction between the first and second projections, wherein the first projection includes a barb engaging with and piercing a side face of the shield at least one side wall to fasten the gasket to the shield.
Claim 10
Dependent Claim
79 words
An assembly as defined in claim 7 further characterized by said framework of limbs having a first and an opposite second surface, said first surface facing said shield and said second surface facing said circuit board, said first surface being sized and shaped to match the size and shape of said exposed edge of said shield at least one side wall and is placed in confrontation therewith when said barb engages with and fastens the gasket to the shield.
