Definitions

  • the present invention is related to a connector assembly comprising an audio plug and a power plug, respectively, and a jack.
  • the jack is provided with a first and a second set of contacts.
  • the first set of contacts is arranged to mate with the power plug.
  • the second set of contacts is arranged to mate with the audio plug to connect sound reproducing means.
  • the sound reproducing means are appropriate for reproducing stereo acoustic signals.
  • the power plug is appropriate to connect the jack with a voltage supply.
  • each jack is a relatively expensive electromechanical component creating limitations for the mechanical design of the housing in terms of requirements of space and reduced stability.
  • a common approach to provide the necessary space is to make the housing larger. Providing enforcement ribs or similar mechanical elements can increase the stability.
  • both approaches are obstacles in the general trends to reduce the size of a housing even further and to reduce production costs of the device.
  • US patent US6109797A discloses a plug-jack type optical/electrical compatible transfer device used for the transfer of data between digital audio apparatuses or other apparatuses capable of transferring digital signals representing audio/visual information, control information, letters or characters, detected parameter values, image information or the like.
  • the transfer device is capable of identifying the type of inserted plug based on the potentials of electric terminals of the plug.
  • a connector assembly is suggested to solve this problem.
  • the inventive connector assembly comprises an audio plug and a power plug, respectively, and a jack.
  • the jack is provided with a first and a second set of contacts.
  • the first set of contacts is arranged to mate with the power plug.
  • the second set of contacts is arranged to mate with the audio plug to connect sound reproducing means.
  • the sound reproducing means are appropriate for reproducing stereo acoustic signals.
  • the power plug is appropriate to connect the jack with a voltage supply.
  • the jack is provided with a mechanical control means.
  • the mechanical control means is movable between two positions that are effective to enable the first set of contacts and to disable the second set of contacts when the power plug is inserted into the jack.
  • the mechanical control means is also movable between the two positions that are effective to disable the first set of contacts and to enable the second set of contacts when the audio plug is inserted into the jack.
  • the mechanical control means operates a switch enabling and/or disabling the first and second set of contacts, respectively.
  • the switch may comprise an electrical control circuit or it comprises with advantage a movable sleeve inside the jack.
  • the switch comprises a control pin, which is actuated by the audio plug.
  • the power plug is provided with a recess to accommodate the control pin when the power plug is inserted into the jack to prevent actuation of the control pin by the power plug.
  • control pin is resiliently biased into a position enabling the second set of contacts.
  • control pin is provided with a lug extending into a radial direction of the control pin and engaging a slanted slit in the sleeve.
  • the sleeve is rotatably mounted and that the lug and the slit are arranged such that a translational movement of the pin effects a rotational movement of the sleeve.
  • the switch comprises a slidable slider mounted in the jack such that a translational movement of the control pin effects a translational movement of the slider.
  • Fig. 1a shows a first embodiment of the inventive connector assembly, which is denoted as a whole with reference number 1.
  • the contact assembly 1 is incorporated in a housing of an electronic device not shown in the drawings.
  • the device may be e.g. a portable audio device.
  • the connector assembly comprises a jack 2 and a power plug 3.
  • the jack 2 has an outer mantle 4 carrying a plurality of contacts.
  • the two sets of contacts are arranged diametrically opposite on the outer mantle 4.
  • a rotatable sleeve 6 is mounted in a half circular slit 7.
  • the sleeve 6 extends only about 90 degrees in circumferential direction. Hence, the sleeve 6 fills in only half of the half circular slit 7.
  • the sleeve 6 can take two end positions in which it abuts at the respective ends of a circular slit 7.
  • the sleeve 6 is provided with four contact stripes 8a...8d extending on the inner and outer surface of the sleeve 6.
  • the sleeve is resiliently biased into its first end position, which will be described in more detail in connection with Fig. 1c.
  • the contact stripes 8a and 8d contact the power supply contact +, -.
  • contact areas 9a, 9b are contacting the contact stripes 8a, 8d and electric power is flowing from a power supply (not shown) via the power plug 3 and the jack 2 into the device.
  • the first end position is shown in the sectional view in the upper part of Fig. 1a. The section is along the line A - A.
  • the top 11 of the power plug 3 is provided with a central blind bore 12 or recess accommodating a control pin 13.
  • the control pin 13 is shown separate from the jack 2 for illustrative purposes only. In a real embodiment the control pin 13 is arranged inside the jack 2 as shown in Fig. 1c. When the power plug 3 is inserted into the jack 2 the control pin 13 penetrates into the blind bore 12 accommodating the control pin 13. In this way the power plug 3 does not exert any forces onto the control pin 13.
  • Fig. 1b shows the first embodiment of the inventive connector assembly associated with an audio plug 14 having a closed tip 16.
  • the sleeve 6 is rotated into the second end position such that the contact stripes 8a, 8b, 8c of the sleeve contact the second contact set providing the audio signals L, R, and G.
  • the tip 16 of the audio plug 14 abuts at a certain position on the way into the jack 2 against the control pin 13.
  • the control pin 13 is pushed backwards and drives the sleeve 6 from the first end position (Fig. 1a) into the second end position (Fig. 1b).
  • the audio plug 14 When the sleeve 6 reaches its second end position the audio plug 14 is completely inserted into the jack 2. Then, contact areas 17a, 17b, 17c of the audio plug 14 make contact to the contact stripes 8a, 8b, 8c.
  • the second end position is shown in the sectional view in the upper part of Fig. 1b. The section is along the line B - B.
  • Fig. 1c shows sectional views of the jack 2 and the arrangement of the sleeve 6 and the control pin 13 inside the jack 2.
  • the sleeve 6 and the control pin 13 are shown approximately in the middle of their respective travelling paths. I.e. the control pin 13 is approximately pushed half way backwards into the jack 2, and the sleeve 6 is approximately in the middle between its first and second end positions. The middle position is shown in the sectional view in the upper part of Fig. 1c. The section is along the line C - C.
  • the audio plug 14 exerting a translational driving force onto the control pin 13 is not shown in Fig. 1c.
  • a slanted slit 18 is provided in the sleeve 6.
  • a lug 19 fixedly connected with the control pin 13 reaches into the slanted slit 18.
  • a spring 21 resiliently biases the control pin 13 into the most forward position corresponding with a first end position of the sleeve 6 (Fig. 1a).
  • the lug in cooperation with the slanted slit 18 exert a rotational force onto the sleeve 6 until the control pin 13 reaches its most backward position and the sleeve 6 reaches its second end position (Fig. 1b).
  • a half circular sleeve 6 is rotated in a circular slit inside the jack 2.
  • Fig. 2a shows a schematic illustration of a second embodiment of the present invention. Similar or identical elements are denoted with the same reference numbers as in the first embodiment.
  • Fig. 2a shows a second embodiment in association with the power plug 3.
  • the main difference between the first and the second embodiment of the invention is that the second embodiment is provided with a slider 22 replacing the sleeve 6.
  • the power plug 3 can accommodate the control pin into its blind bore 12 and thus the insertion of the power plug 3 does not have any effect on the configuration of the jack.
  • Fig. 2b illustrates the second embodiment in association with the audio plug 14.
  • the insertion of the audio plug 14 pushes back the control pin 13 which then drives the slider 22 translationally into a forward direction, i.e. in an opposite direction of the movement of the audio plug 14.
  • An appropriate mechanical connection between the control pin 13 and the slider 22 is provided to achieve this reversal of the movement.
  • Such mechanical means are well-known in the art and do not make part of the subject matter of the present invention. Therefore, the details of this mechanism are not shown in Fig. 2a and 2b.
  • the translational movement of the slider 22 is effective to contact the appropriate contacts of the jack and the contact areas of the power plug 3 and the audio plug 14, respectively.
