Abstract
An electromagnetic interference shield having a main enclosure and at least one auxiliary enclosure. The auxiliary enclosure in the main enclosure and an interior that is continuous with each other. The auxiliary enclosure is made of elastic Faraday material. The outer layer and inner layer may be transparent to view the electronic device. An auxiliary cable with filtering mechanisms may be provided inside a sleeve to allow access and transfer of data from the electronic device while still in the main enclosure.
Claims18
An electromagnetic interference (EMI) shield, comprising:
- (a) a main enclosure to shield an electronic device from electromagnetic interference, the enclosure, comprising:
- (b) a protective layer having a transparent window,
- i. a shielding layer having a transparent portion overlapping the transparent window,
- ii. a first opening to receive the electronic device, and
- iii. an orifice through which a device cable connectable to the electronic device can exit;
- (c) a sleeve having a first end and a second end opposite the first end, the first end of the sleeve operatively associated with the enclosure for accessing and connecting to the electronic device while the electronic device is inside the enclosure, without compromising shielding from the electromagnetic interference, the sleeve, comprising:
- i. an inner layer for shielding;
- ii. an auxiliary cable housed inside the sleeve, the auxiliary cable, comprising a first cable-end connection at a first end and a second cable-end connection at a second end;
- iii. a metallic unit fastened to the second end of the sleeve, the metallic unit mated with the second cable-end connection;
- iv. an EMI filter connected to the first cable-end connection, wherein the first cable-end connector is connectable to the device cable;
- and
- (d) an auxiliary enclosure attached to a second opening in the main enclosure, the auxiliary enclosure fastened to the main enclosure with a shielded seam, the auxiliary enclosure made of a shielding material.
An electromagnetic interference (EMI) shield, comprising:
- (a) a main enclosure to shield an electronic device from electromagnetic interference, the main enclosure comprising:
- i. an outer layer;
- ii. an inner layer enveloped by the outer layer;
- iii. a first opening to receive the electronic device into the inner layer;
- and
- iv. a second opening;
- and
- (b) an auxiliary enclosure attached to the main enclosure at the second opening.
A method of using an electromagnetic interference (EMI) shield, comprising
- (a) being provided with the EMI shield, the EMI shield comprising a main enclosure to shield the electronic device from electromagnetic interference;
- and an auxiliary pouch attached to the main enclosure, wherein the main enclosure comprises:
- i. an outer layer;
- ii. an inner layer enveloped by the outer layer;
- iii. a first opening to receive the electronic device into the inner layer;
- and
- iv. a second opening through which the auxiliary pouch is attached to the main enclosure;
- (b) placing the electronic device through the first opening into the main enclosure of the EMI shield;
- and
- (c) sealing the first opening.
