Description
2337874 1 ELECTRONIC DEVICE AND AN ELECTRICAL CONNECTOR THEREFOR This
invention relates to an electrical connector and especially a flexible connector for coupling together two electronic components to allow a certain degree of freedom of movement.
Many portable devices, such as mobile telephones and personal organisers, include two parts which are hinged together, an electrical connector being provided to connect the electrical components in the two parts. This electrical connector is clearly exposed to wear owing to the frequent opening and closing of the device.
An example of a flexible connector for use with a hinged device is shown in UK Patent application no. 2300 670. This flexible connector has an elongate body which passes though a cylinder in the hinge. This cylinder is designed to enable the connector to be routed so that the hinge elements move without the conductor being damaged.
US Patent no. 5606730 describes a coupler which comprises a wire-like elongate body which undergoes a torsional twisting and untwisting as the device is opened and closed. Thus the wire coupler twists and flexes when the device is opened.
In accordance with the invention there is provided an electronic device comprising: at least a first part and a second part, the first part and second part being movable between a first closed position and a second open position; a hinge for coupling together the first part and the second part, the hinge poviding an axis of rotation and including a knuckle on the first part and a knuckle on the second part; an electrical connector for connecting electronic components housed in the first part and the second part, said connector being routed via the hinge; wherein the electrical connector comprises an elongate 2 body having a helical turn along its length which helical turn extends from within the knuckle on the first part to within the knuckle on the second part.
Preferably the helical turn is a 3600 turn and a 1800 loop is provided adjacent to the helical turn.
In a second aspect of the invention, an electrical connector comprises an elongate body having a helical turn along its length.
In third aspect of the invention an electrical connector for connecting together at least two electronic components, comprises a first and a second end and a first section, one end of which is the first end connectable to a first component; a second section at an oblique angle to the first section for forming a helical turn in the connector; and a third section, parallel to the first, 15 for connection to a second component.
0 ' C 0 1 1 Preferably the electrical connector further comprises: a fourth section connected to the third, at right-angles to the third; a fifth section at fight-angles to the fourth section; a sixth section at right-angles to the fifth, the sixth section having an end connectable to a second component; the third, fourth, fifth and sixth sections being arranged in a step formation leading generally in the same direction as the second section.
In a further aspect of the invention a method of assembling an electronic device having at least two parts coupled together in a hinged manner, said method comprising: taking a connector according to the invention; connecting the first end of the connector to a first component of the device; forming a helical turn from the second oblique portion of the connector; locating the helical turn in a hinge element of the device; and attaching the second end of the connector to the second component.
3 Thus the invention provides a simple connector which may be assembled without additional parts and thus provides an easy assembly implementation. In addition such an electrical connector is able to withstand many open and shut operations of a device since it is only subjected to longitudinal forces 5 along the length of the connector.
The invention will now be described, by way of example only, with reference to the accompanying drawings, in which:
Figure 1 shows a plan view of a first embodiment of a connector according to the invention; q 1, 1 1 - 1--- q 15 1 Figure 2 shows a plan view of a second embodiment of a connector according to the invention in a flat state; Figure 3 shows the connector of Figure 2 in the position adopted when mounted in a device; Figure 4 shows the connector of Figure 2 and 3 in situ in a device; Figure 5 shows a plan view of a third embodiment of a connector according to the invention in a flat state; and Figure 6 shows the connector of Figure 5 in the position adopted when mounted in a device.
The electrical connector as shown in the figures is designed to fit an electronic device having two parts hinged together. One example of such a device is a mobile telephone of the so-called clam- or flip-type. A first part generally houses the display and loudspeaker components and the second part generally houses the keypad, the microphone and other components.
4 The connector is generally extended in form. The connector 2 of Figure 1 comprises a first end 4 for connection to the display and speaker components in a first part of a mobile phone. From the first end 4 of the connector, a first portion 6 leads to a portion 8 at an oblique angle to the first portion. The angled portion 8 is dimensioned so as to fit within the hinge of the device in a manner to be described below. A third portion 10, parallel to the first portion 6, generally extends away from the first portion 10 to provide an elongate body. The end 12 of the third portion of the connector is adapted for connection to components, such as the keypad and microphone (not shown), 10 housed in the second part of the mobile phone.
1.
The second portion 8 is designed to form a helical turn in the connector when mounted in the two parts of a device.
Figure 2 shows a second embodiment of the connector. Parts that are common to Figure 1 are labelled with the same numerals. In the embodiment shown in Figure 2, the end 4 is connected to a sheet 20 which has holes 22. These holes 22 engage with corresponding projections on the first part of the device housing (not shown) to allow for correct positioning of the connector 2 with respect to the housing of the first part and the electrical components therein.
The third portion 10 leads to a fourth portion 24 which is at fight angles to the third portion. The fourth portion 24 leads to a fifth portion 26 which is at right angles to the fourth portion. The fifth portion 26 leads to a sixth portion 28 which is at right angles to the fifth portion. The third, fourth, fifth and sixth portions 10, 24, 26, 28 together form a step arrangement in the connector 2. The distal end of the connector 12 is now the end of the sixth portion 28.
In the embodiment shown in Figures 2 and 3, the third portion 10 of the connector is designed to extend for around 30% of the length of the housing of the telephone and then to execute a 90' turn 29 along fourth portion 24.
This allows the third portion 10 of the connector to fit behind a printed circuit board (PC13) between the PCB and the housing. The connector does not therefore make contact with components mounted on the PC13. The connector is then connected to the surface of the PCB distant from the housing by plugging the end 12 into a connector on the board.
Figure 3 shows the connector of Figure 2 in the position adopted when mounted in a device having two parts coupled together in a hinged manner, the device being in a closed position. For clarity Figure 3 does not show the parts of the electronic device. Figure 4 shows a side view of such a device in a closed position with the connector 2 in dotted outline.
When positioned within the hinge elements of the first and second parts of the device, the connector 2, from the first end 4, executes a 1800 loop 30 formed by the first section 6 followed by a 360 helical turn 32 formed by the second section 8. This helical turn means that the connector travels along the longitudinal axis 34 of the hinge. In the embodiment shown, which is suitable for a mobile phone, the longitudinal extent of the helical turn 32 is of the order of gmm.
As shown in Figure 4, a device 40 comprises a first part 42 and a second part 43 which are coupled together by a hinge 44. The hinge comprises a knuckle 45 on the first part 43 and a knuckle 46 on the second part 44. The connector 2 is shown in position in dotted line. As can be seen, the helical turn 32 is located within the knuckles 45, 46 and allows the connector to connect components in the first part 42 and the second part 43 without getting jammed in the hinge 44 and without additional elements.
The first portion 10 and the second portion 12 of the connector 2 are so 30 proportioned that the loop 30 and the helical turn 32 are sufficiently slack to allow for the opening of the two part device.
6 Figure 5 shows a third embodiment of a connector according to the invention. Again, the same reference numerals are used for parts already described with reference to previous drawings. The connector shown has a first portion 6' which is dimensioned so at to accommodate the formation of a 360' loop from the first portion 6'. The length of the first portion 6' is around 24mm for a connector for a typical mobile phone.
As shown in Figure 6 when the connector shown in Figure 5 is assembled, the connector 2, from the first end 4, executes a 3600 loop 60 formed by the first section 6' followed by a 360' helical turn 62 formed by the second section 8.
This helical turn means that the connector travels along the longitudinal axis 64 of the hinge. In the embodiment shown, which is suitable for a mobile phone, the longitudinal extent of the helical turn 62 is of the order of 9mm.
