Description

M354944 VIII. New description: [New technical field] This creation side is used for the type of reeling device, especially for the use of at least - surge protection single-secret spur signal by - check protection device input and output The end-user interferes with or destroys the internal electronic tree, and detects the reel of the electronic device with detection and protection functions through a control unit and the ship-connecting unit. _ [Prior Art] At present, the signal transmission line f required for products such as computer peripherals and communication peripherals is incapable of passing the age, and the silkworms or the power cords are all transferred together - the use of 'scales easily causes each other's signals Transmission lines are staggered and complicated. Most people usually use bundles, rubber bands, ropes, etc. to bundle the signal transmission lines and release the required length when they are used. • The use of the aforementioned straps, rubber bands, ropes, etc. to bundle the signal lines is too complicated and troublesome, and the overall appearance is not good, which has caused great inconvenience and influence, which has led manufacturers to develop one. Single or double pull reel; and the structure of the conventional single or double pull reel can be found in the Republic of China Patent Bulletin No. M321426 "Single Pull Reel Structure", M263681 "Reel Structure Improvement" , No. 1285183 "Two-way reel" and No. 1285184 "Structure of bidirectional reel". When the general manufacturer assembles the reel, the assembler will cut the length of the required wire (such as the signal transmission line) and then wind the wire in the roll 5 M354944 to complete the assembly of the reel, but Due to the assembly process, the assembler may be slightly inadvertent and cause damage in the wire, resulting in a bad condition of the reel (such as: poor contact, disconnection, short circuit, etc.), and the defective reel is sold to use. On. When the user uses the reel, the end of the reel is connected to an electronic device (such as a computer, a notebook computer, etc.), and the other end is connected to an electronic product (such as a PDA, a mobile phone, an MP3 player, etc.). The product is connected to transfer the information of the electronic device and the electronic product by the reel. At this time, if one of the faults occurs, the user cannot immediately judge which one is damaged, but needs to be repeated by the user. Replace it to confirm which product is damaged. Therefore, users are quite troubled and troublesome, and it is not convenient to use. In addition, when the user starts up or generates a surge (such as Electrostatic Discharge (ESD), it will generate a very high instantaneous current or instantaneous voltage, resulting in an electronic product or electronic device connected to either end of the reel. The electronic components are damaged, which causes considerable inconvenience in use. ► Often, when users use them, they often encounter internal damage caused by electronic products or electronic devices themselves, causing short-circuit phenomena to cause damage to electronic products (or electronic devices). The generated short-circuit current flows to the undamaged electronic device (or electronic product) by the winder, so that the undamaged electronic device (or electronic product) is damaged or burned due to the current of the circuit. The user's psychological or physical face is extremely uncomfortable and inconvenient; therefore, the above-mentioned conventional reel has the following four disadvantages: 1. When the assembly personnel assemble, it is impossible to know whether the wire in the reel is damaged. 6 M3 54944 2. When the electronic production of private electronic shackles - the forest phase scales, the reel can not immediately protect the other - Fang Cong Road The electronic components in the other party are also damaged or burned. 3. When a surge occurs, an instantaneous current scale voltage is generated. At this time, the reel cannot immediately suppress the money or the electronic product. Or the electronic device's cause the electronic components in the electronic product or the electronic device to be damaged. 4. The damage rate is improved.

The role of protection and warning. Furthermore, when the user charges the static portable terminal through the computer (not shown), the chi 6G transmits a warning to the second pin SW' to drive the first-light diode D1.俾 After the user knows that the charging mode L is being charged, the control crystal will transmit a extinguishing signal and an alarm signal to the second pin position sw and the seventh pin position 〇υ τ the second pin position SW After receiving the extinguishing signal, the first light-emitting diode is annihilated,

Ik, that is, the seventh pin position OUT drives the second light-emitting diode to emit light according to the warning signal, so that the user knows that the charging has been completed; at this time, the following two situations occur during the charging process: 1. If the occurrence occurs The charging time exceeds the timing power-off time (such as 13 hours) in the control wafer 60. The control chip 6 immediately transmits the control signal to the seventh pin position OUT to automatically power off, so that the timing power-off and the warning can be achieved. . . 2. If the voltage on the computer is insufficient (that is, the voltage is unstable), the Mp 15 M354944 cannot be charged. By the third pin of the escape control chip 6Q, the sound is strobed and the light is swayed. The second pin is sw, so that the seventh pin is controlled to reduce the voltage output (ie, power off) to stop the charging. At the same time, the second pin SW receives the warning signal to drive the aforementioned first pole. Body D1 can be issued by male first, # % See 7^ 亚 M flashing way to warn the user, with high and low voltage protection and warning. <
