BACKGROUND OF THE INVENTION
1. Field of the Invention
The present disclosure relates to small electrical devices for connection to larger electrical apparatus such as computers. In particular, the present invention relates to devices for insertion into USB (Universal Serial Bus) or HDMI (High-Definition Multimedia Interface) sockets on laptop computers or any other electrical device.
2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 37 CFR 1.98.
Such devices are well known in the art. They include USB or HDMI cables, USB mass storage devices, radio modems and software dongles. Such devices comprise a plug portion and a main body portion housing electrical/electronic components.
When such a device is plugged into a computer or other electronic apparatus it protrudes from the electronic apparatus. There is therefore a risk of knocking the device in such a way that a sheer force may be applied to the electrical socket, causing the device's plug to snap off in the socket. This would cause damage to both the socket and device. Even if the plug does not break off in the socket, the shearing force applied to the plug when the device is knocked can damage the socket and/or the device. This could occur, for example, on dropping a laptop computer.
It is therefore an object to provide a means for reducing the chance of causing damage to a socket when a device plugged into that socket is knocked.
SUMMARY OF THE INVENTION
According to a first aspect there is provided a device for connection into a socket on an electronic apparatus, the device comprising:
a plug portion adapted to be inserted into the socket,
a substantially rigid body, and
a cover connecting the plug portion to the body, wherein the cover includes a flexible joint, and wherein the plug portion is electrically connected to the body through the joint,
wherein the plug portion protrudes from an edge of the cover, and wherein the joint can flex about an axis positioned a fixed distance of less than 15 mm from the edge of the cover from which the plug portion protrudes.
The rigid body houses electrical/electronic components of the device.
The flexible joint enables the substantially rigid body of the device to move about an axis. The flexible joint may be arranged such that there is a single predetermined axis about which the rigid body of the device can move.
When the device is plugged into a socket on an electronic apparatus and the device is hit so that a force is applied to the body, the body will be able to move about the axis in response to the force. This reduces the shearing force applied to the socket, reducing the chance of damaging the socket, and hence reducing the chance of breaking the plug portion off from the rest of the device.
Preferably, the cover is molded in one piece. Molding the cover in a single piece is advantageous as it enables the joint to be positioned close to the edge of the cover from which the plug portion protrudes. Preferably, the joint is formed by an area of reduced thickness in the cover.
The cover may also comprise a shoulder portion at the edge of the cover from which the plug protrudes.
The cover may partially or completely surround and encapsulate the rigid body. The rigid body and the cover surrounding it form a main body of the device.
Preferably, the thickness of the main body is greater than the distance between the axis of the joint and the edge of the cover. If the thickness of the main body of the device is greater than the distance of the joint from the edge of the cover, it will disperse impact energy into the body of the electrical equipment rather than into the socket. Most preferably, the thickness of the main body is about twice the distance of the joint from the edge of the cover.
The joint is preferably made of elastomeric material. More preferably, the cover is made of elastomeric material. All parts of the cover may be made of a single elastomeric material, or different parts may be made of different elastomers molded together. For example, the joint may be made of a different elastomer to the part of the cover from which the plug portion protrudes. The elastomeric material(s) should preferably be rigid enough to enable the plug portion, joint and main body to all lie substantially along the same axis when no force is applied (the rest position). The elastomeric material should also be rigid enough to maintain the rest position if a very small force (a force that could not possibly cause damage to the socket) is applied to the body. However, the elastomeric material must also be flexible enough to allow the joint to bend when a sufficiently large force is applied to the main body.
Having a joint that has an axis positioned less than 15 mm from the edge of the cover from which the plug portion protrudes is advantageous as this decreases the chance of snapping off the plug portion or damaging the socket. If the axis is positioned less than 15 mm from the edge of the cover, when the plug portion is inserted into a socket of an electronic apparatus, there is only a small distance between the edge of the electronic apparatus and the axis.
This is beneficial as it allows the joint to bend very close to the edge of the electronic apparatus, decreasing the shearing force applied to the socket of the electronic apparatus. It additionally decreases the chance that the force will be exerted directly on the portion of the cover of the device lying between the plug portion and the joint.
Therefore, the smaller the distance between the edge of the cover and the axis about which the joint can flex, the less chance the socket will be damaged in response to an external force. Preferably, the joint can flex about an axis positioned less than 10 mm from the edge of the cover from which the plug portion protrudes. More preferably, the joint can flex about an axis positioned about 5 mm from the edge of the cover from which the plug portion protrudes.
The joint may be adapted to flex through at least 45°. Preferably, the joint is adapted to flex through at least 90°.
The joint may be a universal joint. A universal joint is advantageous as it allows the body to flex in all directions relative to the cover. A universal joint may be provided simply by the flexibility of the material of the joint. With a universal joint a number of axes will be provided, all of which are a fixed distance from the edge of the cover from which the plug portion protrudes.
The plug portion may be a USB plug. A USB plug is a rectangular metal connector containing pins for making electrical connection in the socket of an electrical device such as a computer. The USB plug may be any type of USB plug, for example, a standard type A, a standard type B, a mini-A, a mini-B, a micro-A or a micro-B. All these types of USB plug comprise metal pins that are adapted to interact with connections provided in a corresponding USB socket.
Alternatively, the plug portion may be a HDMI plug, or any other plug that can be fitted into an electronic apparatus.
The substantially rigid body may be a USB socket. A USB socket comprises a metal box into which a USB plug can be inserted so that an electrical connection is formed between pins of the USB plug and the socket. Like USB plugs, USB sockets can be many different types, for example, type A, type B, mini-A, mini-B, micro-A or micro-B. A device according to the present invention may comprise a USB plug of one type, and a USB socket of the same or a different type.
Alternatively, the substantially rigid body may comprise a HDMI socket or any other type of socket that enables electronic devices to be connected to electronic apparatus such as laptop computers. It is the components of the socket, for example, the metal box forming part of the HDMI socket, that give the body its rigidity.
The body may alternatively contain a mass storage device, software dongle, or other electrical device. The device may then be a USB flash drive, for example. It is the internal components of the mass storage device, such as the memory storage unit, that give the body its rigidity.

DETAILED DESCRIPTION OF THE DRAWINGS
FIGS. 1 to 7 show two different embodiments of a device. The device shown in FIGS. 1 to 6 is a USB connector, and the device shown in FIG. 7 is a USB mass storage device.
Referring to FIGS. 1 to 6, there is a USB connector 10 for connection into a socket on an electronic apparatus. The USB connector 10 comprises a USB plug portion 12 adapted to be inserted into the socket, a substantially rigid body 15, and a cover 11 connecting the USB plug portion 12 to the body 15. The cover includes a flexible joint 14, and the USB plug portion 12 is electrically connected to the body 15 through the joint 14.
The USB plug portion 12 protrudes from an edge 11a of the cover 11, which may comprise a substantially planar face. In FIG. 1, the joint 14 can bend about an axis X positioned a fixed distance L from the edge 11a of the cover 11 from which the plug portion protrudes and parallel thereto. The distance L is less than 15 mm, preferably less than 10 mm, and most preferably about 5 mm.
The joint 14 is formed by an area of reduced thickness in the cover 11. The joint 14, therefore, forms a neck. The neck is preferably tapered from the direction of the plug towards the joint axis and from the direction of the body towards the joint axis. In this manner opposed upper and lower wedge surfaces are provided either side of the joint axis. Each of the wedge surfaces is preferably arranged at 45 degrees relative to line A-A of FIG. 2.
The area of the cover 11 from which the plug portion 12 protrudes forms a shoulder 13 which defines the edge 11a. The shoulder 13 of the cover 11 surrounds an end of the plug portion 12. The joint 14 provides a flexible hinge joint running across the device along the axis X which separates the shoulder 13 from the main body of the device.
The USB plug portion 12 is a rectangular metal connector containing pins for making an electrical connection in the socket of a computer etc.
FIG. 3 shows a cross sectional view of the connector 10 taken along line A-A of FIG. 2. FIG. 4 shows a cross sectional view of the connector 10 taken along line B-B of FIG. 1. In these cross sectional views, the substantially rigid body shown (15) is a USB socket. The USB socket 15 comprises a rigid metal box. It is the rigid metal box of the USB socket that makes the body substantially rigid. FIGS. 3 and 4 show the USB plug 12 connected to the USB socket 15 by an electrical connection 16 which passes through the joint 14. The cover partially encapsulates the rigid body 15 but leaves open access thereto for the insertion of the plug of another device. The rigid body 15 and the cover surrounding it form a main body of the device.
In the embodiment shown in FIGS. 1 to 6, the cover 11 extends over the USB socket 15 (shown in FIGS. 3 and 4) so that one side is exposed. The cover 11 has been made from a single moulding. Preferably, the cover 11 has been moulded from elastomeric material.
FIG. 5 shows the connector 10 in a bent configuration after it has come into contact with surface 17. The USB plug portion 12 of the connector 10 is shown inserted into a USB socket 19 in part of the body of a laptop computer 18.
Surface 17 was moved in direction C towards the connector. When the surface 17 came into contact with the connector 10, the joint 14 bent, enabling the body of the connector 10 to move in direction D thus reducing the sheer force applied to the USB plug portion. The joint 14 has flexed through at least 45°. As the sheer force is reduced, the chance of the USB plug portion 12 being broken off in the socket 19 of the computer 18 is reduced.
FIG. 6 shows the connector 10 in a bent configuration after it has come into contact with surface 17a. Surface 17a was moved in direction E towards the connector. When surface 17a came into contact with the connector 10, the joint 14 bent, enabling the body of the connector 10 to move in direction E.
In FIG. 6, the joint has flexed through slightly more than 90° so that the part of the cover 11 has come into contact with the edge of the computer. Because the thickness of the main body of the device is greater than the distance L, the distance L2 from the edge of the computer to the impact point 28 is also larger than the distance L from the edge of the computer to the flexible joint. As a result, most of the impact energy is transmitted from point 28 straight to the body of the computer at point 26. As the cover 11 is made from an elastometric material, this impact energy will be mostly absorbed, both by the cover 11 and by the case of the computer 18. The amount of energy transmitted to points 27 at the socket surface will be minimal, and not enough to cause damage to the socket. Preferably, the thickness of the main body is about twice the distance L. In the position shown in FIG. 6, the upper surface of the device has, by virtue of the joint (with its tapered surfaces either side of the axis) been brought into a position in which it is substantially co-planar with the front face 11a. The faces here are not fully co-planar, since the joint has allowed for a flex through slightly more than 900. With arrangements in accordance with the present disclosure it is preferable that these faces may be brought into close alignment.
Referring to the alternative embodiment shown in FIG. 7, there is a mass storage device 20 comprising a USB plug portion 22 adapted to be inserted into the socket, a substantially rigid body 25, and a cover 21 that connects the USB plug portion 22 to the body 25. The cover includes a flexible joint 24, and the USB plug portion 22 is electrically connected to the body 25 through the joint 24. The USB plug portion 22 protrudes from an edge 21a of the cover 21. The joint 24 can bend about an axis Y positioned a distance L3 from the edge 11a of the cover 21 from which the plug portion protrudes. The distance L3 is less than 15 mm, preferably less than 10 mm, and most preferably about 5 mm.
In this alternative embodiment, the body 25 is the electronics unit of the mass storage device 20. The cover 21 of the device completely surrounds the body. The cover 21 comprises a shoulder 23 at the end of the cover 21 from which the USB plug portion 22 protrudes. All features of the device of FIGS. 1 to 6 can be applied to the device of FIG. 7 as appropriate.
