Description of the Invention (1) Field of the Invention The present invention relates to a reel device for a receivable discharge wire. The present invention is particularly related to a small-sized retractable discharge wire reel device which is suitable for use in a handheld electronic device such as a mobile phone. BACKGROUND OF THE INVENTION A retractable discharge wire reel device can be used to send and automatically retrieve electrical wires used to connect parts of one device to another. This connection system can be electronic, as in the case of, for example, a small mobile phone, and in such an example, a releasable cable reel system can be used to connect a microphone with an earphone or a pair of earphones To the phone base unit printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs (please read the note on the back? Matters before filling out this page). Most of the wire spools include a rotating spool, and a receivable discharge wire is Hold on this spinning reel. Some conventional devices provide a rotating electrical contact between the spool and the spool housing or base element. In electronic devices, especially those that contain low-current signals, mobile contacts can cause static electricity and other unexpected signal interruptions. In addition, the contact system is not very durable, and the quality of electronic contacts will be affected by wear and tear. One solution to the rotary contact is to place a second cable (typically flat) in the wire reel, which is retracted and retracted when the retractable discharge cable is retracted and returned The system will expand and contract. For example, see U.S. Patent No. 5 '0 9 4' 3 96 of Pa U 1 C. Burke. However, this type of wire reel 4 paper size applies to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 473454 A7 B7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economy The use of small electronic devices, such as telephones, may appear to be too large. In particular, the scroll system disclosed in Burke's US Patent No. 5,094,396, has a plurality of compartments, and For retractable discharge wires, expandable cables, springs, and ratchets. Because the casing is quite large, it will not be suitable for integrating it into a small electronic device such as a mobile phone. Stomach_Earth The design in many conventional techniques does not properly address the issue of equivalent stress. This stress is a mobile part located on these small reels. ° When the headset is pulled out of the phone, a considerable amount of stress is generated. Large stress. After repeated use, this stress usually causes small braided wires (such as Litzwire) and other components used in conventional reel devices. Failure of the electrical connection or mechanical failure. Larger, more durable cables are not practical because I need a small reel size and because I need a lightweight for headphones and / or microphones The reason for flexible wires. Similarly, 'the wire reel device suitable for many small electronic devices in many conventional technologies does not provide sufficient shielding of electronic signals to prevent interference. This problem is for small phones and microphones that use very low voltage and It is particularly serious for headphones. Inadequate shielding can cause cross talk and other electronic noise. Many conventional braided wires, small cable reels, and small cable housings are sacrificed for the small size. Therefore, there is still an unresolved demand for the wire reel device, and this demand is in line with, for example, a mobile phone, etc. (Please read the precautions on the back before filling out this page )-— — — — 111 ^ OJ · 1111111 »— — — — — — — — — — — — — — — — —

The ratchet system may include a pawl 2 8 ′. The pawl 28 is pivotally mounted to the bottom plate 16 and the spring 29. The bobbin 2 is provided with a groove 8 2. The spring 29 is used to deflect the pawl 28 to engage the notches 82 and to selectively prevent the spool 2 from rotating in the direction in which the wire is retracted. A release lever (not shown) is provided for disengaging the pawl 28 from the notch 82 to allow the spring to rotate the bobbin 2 in the wire retracting direction. Ratcheting in this article is only one example of a suitable ratcheting. Other ratcheting mechanisms known in the art can be used. In addition, although the ratchet system is desirable in most applications, since the present invention can be operated without any ratchet teeth, the ratchet teeth are not required by the invention. The fourth figure is a cross-sectional view of the receivable discharge line 10. The receivable discharge wire 10 is preferably composed of a plurality of individually insulated inner conductors 50. At least one of the conductors is preferably shielded by a conductive layer 52. An outer reinforcing layer 54 surrounds these conductors. The shielding layer 5 2 is preferably composed of a copper braid layer. The reinforcing layer 54 is preferably composed of a nylon woven layer, and can have excellent strength, a relatively small size, and light weight. The fiber braid layer 54 is preferably connected to the bobbin 'to limit the stress / strain on the conductor, but in some applications it is not necessary to connect the reinforcement layer to the bobbin. The connection can be made in any way, for example by mechanically connecting the braided layer to the bobbin 2 via a bolt 80, as shown in the third figure. Mechanical connection can be achieved by pulling one of the end parts of the better nylon braid layer 5 4 back to 16 (please read the precautions on the back before filling this page) 0 11111 line-win paper size applicable to Chinese national standards (CNS ) A4 size (210 X 297 mm) 473454 A7 B7 printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 5.

Alternatively, the inner cable 22 may include a flat ribbon cable that is adhered to or separated from the spring, or a separate insulated conductor is attached to the spring 2 2 or the spring 2 2 becomes one. Other variations are quite obvious to those skilled in the art, including a spring made of a non-conductive polymer with a spring-like elastic memory, while the inner cable 2 4 includes There are separate conductors that are plated or deposited thereon. However, 'a metal spring system is preferred because polymer spring systems have been found to lose their elastic memory faster than metal springs. The inner cable 2 4 is opened through the bobbin annular wall 12 and is conductively connected to the conductor 50 of the receivable discharge wire. Conductive connections can occur by bonding, by terminal connections, or by other means known in the art. Alternatively, the conductive system of the receivable discharge wire 10 may be a single conductor with the conductor of the inner cable 24. At the junctions adjacent to the opening 12 of the annular wall, some gaps can be provided in the conductors to provide strain relief so that when the receivable discharge line 10 is dragged, The stressed mechanical load is carried by the fiber braid 54 instead of the conductors 50. This system helps prevent the failure of these conductors 50 and allows a relatively small braided conductor 50 to be used so that the receivable discharge wire 10 can be relatively small, lightweight, and flexible. Sexual. It should be understood that, although the retractable discharge line and the inner cable system shown and described have ends and are combined, the retractable discharge line and the inner 18 paper standards are applicable to the Chinese National Standard (CNS) A4 specification ( 210 X 297 mm) (Please read the precautions on the back before filling out this page). · # -------- Order_1 ------- 1 Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs System 473454 A7 B7 5. Description of the invention (A) The side cable can be a single wire. Therefore, the term 'receivable discharge line' shall refer to the part of the cable that can be retracted, and the term inside cable t shall refer to the part of the wire located in the inside compartment 6. In fact, in some applications it is acceptable, or even desirable, to have a flat ribbon retractable cable system, and in this example, the inner cable 24 and the retractable discharge cable 1 0 The system can be part of a single, continuous cable. It would also work to make a single wire that includes a flat section (like the inside cable) and a round section (like the retractable discharge wire). These and other variations are easily understood by those skilled in the art, and are intended to be included in the scope of the present invention with the scope of the attached patent application. In order to further improve the performance of the conductor of the present invention with respect to the degree of freedom from electromagnetic interference, the plurality of conductors 102 of the preferred inner cable 24 of the present invention includes at least one shielded conductor. In the case of mobile phones, the system requires two conductors, one for the headset and the other for the microphone. The inner cable shown in the fifth figure is composed of four conductors. The two conductors 106 and 108 on the left can be used for earphone signals, while the conductor on the far right 1 10 can be used for microphones. Between them is a shielded conductor 1 1 2. The low-output microphone signal carried by the conductor 1 10 is shielded by the shield conductor 1 导体 2 on the left side, shielded by the spring 2 2 on the upper and lower sides, and by the other on the right side. Shielded by a shield carried by the spool or housing. The shield conductor 1 1 2 is conductively connected to the spring 2 2, the bobbin shielding layer 4 8, and the retractable discharge wire shielding layer 5 2, thereby providing a common continuous shield.

Description of the Invention (Λ) The handset group in the figure does not require a shielded conductor 1 1 2. Although four separate conductors 102 are shown in the fourth figure, the present invention may include any number of conductors required for a particular application. Likewise, as discussed below, other configurations of the conductor 102, the insulating layers 104 and 100, and the spring 22 are within the scope of the present invention. The present invention solves several problems in the conventional technology by winding the inner cable 24 with a spring 22. First, precious space is saved; no separate chambers are needed. If, as is the case, the conductors 102 and the insulation layers 100 and 104 are supported by springs 2, the system can be relatively thin and flexible without the high risk of failure. . This department offers additional space savings. Furthermore, the conductors 102 are in an excellent EMI-R F I shielded environment without the need for a separate shield. In particular, above and below these conductors are metal springs 2 2, shield conductors 1 1 2 on one side, and cover 3 3 and / or spools on the other side. The nickel plating on the wall part can shield the EMI I-RFI. When separate shielding is not required for the individual conductors 102, additional space savings can be achieved. The advantages of the present invention can be achieved in an economical, practical, and easy manner.
