  • FIG. 6 shows the connector of FIG. 5 in the position adopted when mounted in a device. [0018]
    • DETAILED DESCRIPTION OF THE INVENTION
  • 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. [0019]
  • The connector is generally extended in form. The [0020] connector 2 of FIG. 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), housed in the second part of the mobile phone.
  • The second portion [0021] 8 is designed to form a helical turn in the connector when mounted in the two parts of a device.
  • FIG. 2 shows a second embodiment of the connector. Parts that are common to FIG. 1 are labelled with the same numerals. In the embodiment shown in FIG. 2, the end [0022] 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 [0023] third portion 10 leads to a fourth portion 24 which is at right 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 FIGS. 2 and 3, the [0024] 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 (PCB) between the PCB and the housing. The connector does not therefore make contact with components mounted on the PCB. 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.
  • FIG. 3 shows the connector of FIG. 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 FIG. 3 does not show the parts of the electronic device. FIG. 4 shows a side view of such a device in a closed position with the [0025] connector 2 in dotted outline.
  • When positioned within the hinge elements of the first and second parts of the device, the [0026] connector 2, from the first end 4, executes a 180° 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 9 mm.
  • As shown in FIG. 4, a device [0027] 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 [0028] first portion 10 and the second portion 12 of the connector 2 are so proportioned that the loop 30 and the helical turn 32 are sufficiently slack to allow for the opening of the two part device.
  • FIG. 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 [0029] 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 24 mm for a connector for a typical mobile phone.
  • As shown in FIG. 6 when the connector shown in FIG. 5 is assembled, the [0030] connector 2, from the first end 4, executes a 360° 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 9 mm.
