## Title
Positive locking mechanism for USB connected devices

## Abstract

The present invention is a positive locking mechanism for a universal serial bus (USB) connector which includes at least one mounting portion connected to the USB connector with the mounting portion having an aperture. The present invention also includes at least one flange in proximity to the mounting portion, with the flange having an aperture, as well as a fastener inserted through the aperture of the flange and the aperture of the mounting portion, where the fastener is used to connect the mounting portion to a structure.

## Background
FIELD OF THE INVENTION
The present invention relates to universal serial bus (USB) connectors. More particularly, the present invention relates to a positive locking mechanism for a USB connector for securing a USB connector to a device used for communicating with a computer.
BACKGROUND OF THE INVENTION
USB connectors and cables are generally known. There are two common types of USB connectors. One type of connector is called an “A connector,” and the other type of connector is what is referred to as a “B type connector.” The first type of connector, an A connector, is used for heading “upstream” toward the computer, and the second type of connector, the B connector, heads “downstream” and connects to an individual device used for communicating with the computer. These types of connectors are used to allow various external devices, such as printers, scanners, fax machines, keyboards, a mouse, a personal digital assistant (PDA), and other devices to communicate with the computer. To connect the USB cable to the device and the computer, each connector of the USB cable simply plugs in to a corresponding port on the computer or the device. However, with typical USB connectors, there is no locking mechanism used for securing the connection between the connector and the connector's corresponding port. Therefore, certain types of handheld devices, such as PDAs or diagnostic tools, which are used and moved around quite frequently, can become inadvertently disconnected from the USB connector.
Therefore, there exists a need for an improved USB connector which can be secured to a device that is used to communicate with a computer.
SUMMARY OF THE INVENTION
The present invention is a positive locking mechanism for a universal serial bus (USB) connector which includes at least one mounting portion connected to the USB connector, with the mounting portion having an aperture. The present invention also includes at least one flange in proximity to the mounting portion, with the flange having an aperture, as well as a fastener, inserted through the aperture of the flange and the aperture of the mounting portion, where the fastener is used to connect the mounting portion to a structure.
Further areas of applicability of the present invention will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The following description of the preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.
A universal serial bus (USB) connector cable incorporating a positive locking mechanism according to the present invention is shown in the Figures generally at 10. The cable 10 includes two different types of standard connectors, the standard “A connector” 12, and the standard “B connector” 14, with the exception that a positive locking mechanism, according to the present invention and generally shown at 16, is incorporated into the B connector 14. The A connector is typically connected to a computer (not shown) and the B connector 14 is typically connected to a device (not shown) which is used for communicating with the computer.
The operation of the USB cable 10 is similar any other standard USB cable, and therefore is not described herein. The B connector 14 includes a protective molding 18. A portion of the molding 18 is part of the positive locking mechanism 16. Formed in the molding 18 is a mounting portion in the form of a pair of mounting blocks 20, which are part of the positive locking mechanism 16. Each of the mounting blocks 20 has an aperture 22 which extends through each of the mounting blocks 20. The positive locking mechanism 16 also includes a fastener, such as a bolt 24, which extends through each of the apertures 22; each bolt 24 has a threaded portion 26 and a head portion 28. Each of the mounting blocks 20 also includes a first mounting face 30 and a second mounting face 32.
Also included in the positive locking mechanism 16 are a pair of flanges, shown generally at 34, each of the flanges 34 includes a flat portion 36 which has an aperture 38 through which each of the bolts 24 extend, as shown in FIGS. 3 and 4. Each of the flanges 34 also includes two angled portions 40. The flat portions 36 of the flanges 34 serve the purpose of distributing the load applied from the bolts 24 as they are tightened (the purpose of which will be described later).
When the USB cable 10 is to be attached to a device for use, the A connector 12 is plugged into a computer and the B connector 14 is plugged into a device which will be used to communicate with the computer, such as a diagnostic tool, shown schematically at 42. Once the B connector 14 is attached, the bolts 24 will be screwed into a corresponding threaded aperture (not shown) attached the device such that a tension force is applied to the bolt 24, thereby fixedly mounting the B connector 14 to the device. The bolts 24 are tightened so each of the first mounting faces 30 is in contact with the device the B connector 14 is to be connected to, and each of the second mounting faces 32 is in contact with the flat portion 36. The tension force from the bolts 24 being attached to the device is transferred through the flat portions 36 of the flanges 34 and to the mounting blocks 20, thereby applying a compressive force to the mounting blocks 20. The flat portions 36 of the flanges 34 aid in disbursing the tension load onto the mounting blocks 20 from the bolt 24, this prevents the heads 28 of the bolts 24 from being forced into the apertures 22 of the mounting blocks 20 when the bolts 24 are under load.
The threaded portion 26 of the bolt 24 does not extend the entire length of the bolt 24. The threaded portion 26 is limited to the area of the bolt 24 which is received into the threaded aperture of the device the B connector 14 is connected to. The remaining portion of the bolt 24 that is not threaded is disposed within the apertures 22 of each of the mounting blocks 20.
The description of the invention is merely exemplary in nature and, thus, variations that do not depart from the gist of the invention are intended to be within the scope of the invention. Such variations are not to be regarded as a departure from the spirit and scope of the invention.
