BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to shielding and coupling and more particularly to an improved apparatus for shielding an electronic storage device and an improved apparatus for coupling an electronic device to a computer device.
2. Background of the Invention
USB flash drives are memory data storage devices integrated with a USB interface. USB flash drives are preferable over many other data storage devices in that the USB flash drives are typically small, lightweight, removable and rewritable. The USB flash drives consist of a small printed circuit board encased in a plastic or metal casing. A USB connection allows the USB flash drives to connect directly to a port on a personal computer. The plastic or metal casing makes the USB flash drives sturdy enough for transporting singularly or in conjunction with a lanyard or key ring. In a typical USB flash drive only the USB connector protrude from the plastic or metal casing.
Since the USB connector extends outside of the plastic or metal casing, the connector is vulnerable to damage by striking a foreign object or intrusion of particles or moisture. In addition, once the connector is engaged into the port on a personal computer, the casing extends outside of the personal computer. If the casing is stuck while the casing is engaged with the port on a personal computer, the USB connector and/or the port may be damaged. The following U.S. patents are examples of attempt of the prior art to solve these problems.

Furthermore, the plug cap 130, the housing cap 150 and the elastic tether 180 may be constructed from a translucent polymeric material 198 to permit transmission of light rays generated from the light emitting device 106 through the sleeve 10.
As best seen in FIGS. 1, 3, 5, 7-10, 34, 35 and 43, the elastic tether 180 is deformable for providing a first length 200 during the plug cap 130 engaging the plug 24 for concealing the plug 24. More specifically, the elastic tether 180 applies a compressive force between the plug cap 130 and the housing cap 150 for maintaining the first cap engaging surface 138 adjacent to the housing engaging surface 20, the second cap engaging surface 146 adjacent to the finger engaging surface 20 and the input end 25 of the plug 24 adjacent to the cap end 135 of the plug cap 130. The direct contact between the first cap engaging surface 138 with the housing engaging surface 20, between the second cap engaging surface 146 with the finger engaging surface 20 and between the input end 25 of the plug 24 with the cap end 135 of the plug cap 130 protects the plug 24 from moisture, debris and/or damage from striking a foreign object.
As seen in FIG. 44, the elastic tether 180 is deformable for providing a second length 202 during which the plug cap 130 is displaced above the plug 24 for inserting or removing the plug bore 132 from the plug 24. The operator 8 is able to seize the housing 14 without making contact with the sleeve 10 by positioning the operator's thumb 212 and index finger 214 of the operator's right hand 210 on the recessed concave portion 64 and raised convex portion 69 respectively. The operator is able to seize the plug cap 130 without making contact with the housing 14 by positioning the operator's thumb 222 and index finger 224 of the operator's left hand 220 on the cap concave portion 174 and cap convex surface 176 respectively. The operator 8 displaces the plug cap 24 from the housing 14 by applying opposing forces to the housing 14 and the plug cap 24. The elastic tether 180 expands in length to disengage the plug cap 24 from the housing 14. As seen in FIGS. 2, 4, 6, and 36-42 the elastic tether 180 is deformable for providing a third length 204 during removal of the plug cap 130 from the plug 24. The polymeric material 196 may include a high flexibility such that the plug cap 130 can be distance from the plug 24. While the plug cap 130 is removed from the housing 14, the elastic tether 180 is in a relaxed state. During the relaxed state, the third length 204 of the elastic tether 180 is less than the length of the first length 200 of the elastic tether 180 in order to provide a compressive force between the housing 14 and the plug cap 130 during the plug cap 130 engaged with the plug 24. The compressive force between the housing 14 and the plug cap 130 assures that the first cap engaging surface 138 remains adjacent to the housing engaging surface 20, the second cap engaging surface 146 remains adjacent to the finger engaging surface 20 and the input end 25 of the plug 24 remains adjacent to the cap end 135 of the plug cap 130. The direct contact between the first cap engaging surface 138 with the housing engaging surface 20, between the second cap engaging surface 146 with the finger engaging surface 20 and between the input end 25 of the plug 24 with the cap end 135 of the plug cap 130 protects the plug 24 from moisture, debris and/or damage from striking a foreign object. The engagement between the first orifice 160 with the first step 44 and between the second orifice 162 with the second step 46 prevents the sleeve 10 from being accidentally separated from the housing 14 while the plug cap 130 is removed from the housing 14.
As best seen in FIGS. 2, 4, 6, 44 and 45, when the plug cap 130 is engaged with the plug 24, a first majority portion 230 of the first elastic strand 182 is positioned adjacent to the bottom surface 32 and a first minority portion 232 of the first elastic strand 182 is positioned adjacent to the first side surface 34. Furthermore, when the plug cap 130 is engaged with the plug 24, a second majority portion 234 of the second elastic strand 182 is positioned adjacent to the bottom surface 32 and a second minority portion 236 of the first elastic strand 182 is positioned adjacent to the second side surface 36. The first and second majority portions 230 and 234 permits the plug 24 to be easily pivoted towards the bottom surface 32 of the housing 14 and hinders the plug 24 to be pivoted towards the top surface 30 of the housing 14.
