New description: [New technical field] The present invention relates to an overcurrent power-off protection socket, in particular to an adjustable over-current power-off protection socket. [Prior Art] The power supply is inserted into the power supply by the socket, and the power supply is inserted to supply the power required for the operation of the electrical appliance. 1 is a schematic diagram of a conventional socket, which is provided with a pair of wires 200 extending to the outside and electrically connected to a power source. The socket body 100 is provided with a plurality of pairs of jacks 300. Parallel to the pair of wires 200. The plug of the electrical appliance is inserted into the socket 300 of the socket body 100 to obtain power. However, during the use of electrical appliances, there may be current overload, high temperature, or even fire due to leakage, short circuit, overload, and excessive contact resistance. The traditional socket has no overload protection device, and can not automatically cut off the power when the current is overloaded. The use of the upper pole is unsafe. In order to avoid the disadvantage that the conventional socket cannot automatically cut off the power when the current is overloaded, the manufacturer has designed a safety socket as As shown in FIG. 2, it is provided with a fuseless switch 240 on one of the wires of the pair of wires 200. When the current is overloaded and exceeds the rated current value set by the no-fuse opening 240, it will automatically break off ( OFF) to cut off the power. The fuseless switch 240 of the general safety socket is set to have a safe rating. 3 M418467 constant current value, usually set at ampere or 15 amps (depending on the wire diameter of 1.6mm or 2, Omm). 5毫米平方的的的的。 The electric wire of the electric wire may be 0. 75mm square (its safety current is 7 amps), and even the wire used by many gods may be only 0. 5mm square (its t The full current is 4 amps. 'The safety current value of the socket is 15 amps, which is significantly higher than the safe current value of the wires of the electrical appliance, such as 7 amps or 4 amps, which cannot function as overload protection. That is, when the electrical wire of the electrical appliance φ is overloaded (for example, more than 7 amps or 4 amps), since the overload current still does not reach the safe current value (15 amps) set by the socket, the socket is considered to be still safe. Within the scope of use, there is no immediate power failure and the protection of overload and power failure is achieved. That is to say, although the safety socket has an overload protection device on its own line, it is not possible to make different electrical load (such as a magic lamp and an electric heater) due to different load or matching extension wire diameters. The protection action of the current limit can not be surely achieved to achieve the overload and power failure. Another situation is that there is a conductive phenomenon on the wires and sockets. In the initial stage, the fault current may only be 2 amps, but it has been generated. 1GG ~ degree high temperature, at this time the plug may be in the stomach smoke but the protection switch does not cut off the power supply because the current value does not exceed 15 amps. The most ^, ^ example is the extension line with or without fuse protection, the wire will still be ignited due to the pollution of the conductive or gold insulation phenomenon. Due to the above reasons, the application of the conventional safety socket is not good. 4 M418467 [New content] In view of the shortcomings of the above-mentioned conventional safety sockets, the purpose of the present invention is to provide an adjustable overcurrent power-off protection socket that can adjust the rated current value according to the type of load and achieve the protection effect. According to the above object, an embodiment of the present invention provides an adjustable overcurrent power-off protection socket, comprising: a socket body; a pair of wires disposed inside the socket body and electrically connected to the socket body The power supply, the pair of * wires have a first wire and a second wire; at least one pair of sockets are opened in the socket body and are connected in parallel between the pair of wires, each pair of jacks has a first socket and a first socket The second jack is electrically connected to the first lead; and the at least one adjustable overcurrent protection unit is electrically connected between the second jack and the second lead. According to the adjustable over-current protection unit of each pair of jacks, the rated current value of each pair of jacks can be adjusted corresponding to the load of the electrical devices inserted in each pair of jacks, when any pair of jacks When the inserted electrical appliance is overloaded or the current rises abnormally, the power supply to the jack with the overload or current abnormality φ rises immediately, and the possible disaster is prevented. According to an embodiment of the invention, the adjustable overcurrent protection unit comprises: a plurality of fuses having different rated current values for each setting, and being separated from each other; and a switch, switching selected and electrically connected to the majority of the fuses•• One of the fuses electrically connects the switched selected fuse to the second jack and the second lead. Used to select a fuse that matches the rated current value relative to the load of the inserted appliance. According to an embodiment of the present invention, the switch is a manual switch or a power switch, and the cut M418467 switch can be operated manually or electronically. According to an embodiment of the present invention, the fuse is a self-resetting fuse (pptc), and when the overload condition is released, the fuse can automatically return to the on state. According to an embodiment of the present invention, the second wire is provided with a fuseless switch, which is set to have a safe rated current value to protect the socket from being overloaded when the load exceeds the safe rated current value to avoid a disaster. According to an embodiment of the invention, the pair of wires extend beyond the outer portion of the socket body and are provided with a plug for insertion into other sockets having a power source to obtain power. [Embodiment] The foregoing and other technical contents, features, and advantages of the present invention will be apparent from the following detailed description of embodiments referring to the drawings. 3 and 4 are respectively a circuit diagram of an adjustable φ-type overcurrent power-off protection socket according to an embodiment of the present invention, and a schematic structural view of the adjustable over-current protection unit. As shown in the drawings, an adjustable overcurrent power-off protection socket according to an embodiment of the present invention includes a socket, a body 100, a pair of wires 200, three pairs of jacks 300, and three adjustable over-current* flows. Protection unit 400. The pair of wires 200 are disposed inside the socket body 100, and the pair of wires 2b have a first wire 210 and a second wire 220. The pair of wires 200 are electrically connected to a power source (not shown). In practice, the pair of wires 200 can be directly electrically connected to a power source, or as shown, the pair of wires 200 extend 6 M418467 to the socket body 100. The outside is provided with a plug 230 for plugging into other sockets having a power source for power supply. In addition, the second wire 220 is provided with a no-fuse opening 240, which is set to have a safe rated current value, for example, 15 amps, as the maximum protection current value of the socket; when the load of the socket, the load flowing through the second wire 220 exceeds 15 amps. When the fuseless switch 240 is turned off, the power is turned off to protect the socket and its load to avoid high temperature, damage and fire caused by overload. The three pairs of jacks 300 are respectively a first pair of jacks 300A, a second pair of jacks 300B, and a third pair of jacks 300C; each pair of jacks 300 is formed in the socket body 100 and is connected in parallel between the pair of wires 200 . Each of the pair of jacks 300 has a first jack 310 and a second jack 320. The first jack 310 is electrically connected to the first lead 210, and the second jack 320 is connected to the adjustable overcurrent protection unit 400. The second wire 220 is electrically connected. The three adjustable overcurrent protection units 400 are respectively a first adjustable overcurrent protection unit 400A, a second adjustable overcurrent protection unit 400B and a φ3 adjustable overcurrent protection unit 400C, each adjustable overcurrent The protection units 400 each include a plurality of fuses 410 and a switch 420. For example, four fuses 410 are the first fuse 411, the second fuse 412, the third fuse 413, and the fourth fuse 414, which are disposed apart from each other, and each setting has a different rated current value, for example, 0. 05 amps (for example, suitable for appliances below 5W), 0 amps (for example, appliances suitable for 55W or less), 7 amps (for appliances suitable for 550W or less) and 15 amps (for example, appliances suitable for 1650W or less) Use the load value of the appliance. When each fuse 410 is equipped with an electrical load that exceeds the rated current value of 7 M418467 set by the fuse 410, each of the fuses forms an open circuit; for example, when the second fuse 4i2 is equipped with an electrical load of more than 0.5 amps, The second fuse 412 forms an open circuit. In practice, the fuse 41() can be selected from a self-resetting fuse (PPTC ^ Polymerlc Positive Te.perature Coefficient

The switch 420 is, for example, a knob switch, which is switchably selected and electrically connected to the recording security 4, such as the second fuse 412', electrically connecting the second fuse 412 selected by the broken switch to the first The second jack 320 and the second lead 22 are. The switcher can be a manual switcher, which can: operate the switch manually; the switch 42 can also be an electric switcher, which can operate the switch electronically. . That is to say, the switcher selects the switch of the fuse, in addition to the manual operation, it can also use the electronic signal to control the relay or the electronic circuit to switch the selection. For example, the TV or the electric appliance is in the _ (the basin is a cow) People can wake up at any time with the remote control. They can be sent synchronously by wire or wirelessly. The electronic (4) to the (4) on the socket will immediately switch to the fuse position of the current protection (depending on the power consumption value during standby). For example, the 'visible appliance switches the protection current in the standby state or the use state. For example, when people go out, they can simultaneously transmit the electronic signal to the switcher via the door's induction control, or wirelessly, depending on the demand. The protection limit is switched to small amp protection (for example, when the home is unmanned, the circuit is only used for standby power 1Gw, that is, about G.G1 ampere). If the electrical fault occurs or the M418467 line abnormality causes the current to rise, the power can be immediately cut off. The adjustable over-current power-off protection socket according to an embodiment of the present invention is adapted to adjust the adjustable over-current protection unit according to the load value of the electrical appliances to be inserted in each pair of jacks 3 4 〇〇 position. For example, in the first pair of jacks 3A, a small night light is to be inserted (not shown, its power is about 5W 'the rated current of the wire is about 〇. 〇5 amps), then it corresponds to the first The adjustable overcurrent protection unit 4〇〇a switches its position to the first fuse 411 with its switcher 420; a luminaire is inserted at the second pair of jacks 300B (not shown] its power is about 55W, the wire The rated current is about 〇5 amps', and the corresponding second adjustable overcurrent protection unit 4〇〇B is switched with its switch 420 to the position of the second fuse 412; at the third pair of jacks 300C When an electric cooker (not shown, the power is about 77 〇w, the rated current of the electric wire is about 7 amps), the corresponding third adjustable overcurrent protection unit 400C is switched to the third switch with its switch 420. The position of the fuse 413. According to this, when the small night light on the jack 300A causes the load current to exceed 0·05 amp due to line leakage or short circuit, the first adjustable overcurrent protection unit 4〇〇a is first. The fuse 411 forms an open circuit, and immediately stops the supply of the night light to avoid high temperature, damage, and fire; similarly, when the load current of the luminaire on the second pair of jacks 300B exceeds 〇. 5 amp - pe. The second fuse 412 of the first adjustable overcurrent protection unit 400B forms an open circuit; similarly, when the load of the electric cooker on the third pair of jacks 300C is more than 7 amps, the third adjustable overcurrent protection unit The second fuse 413 of 4〇〇c forms an open circuit, and the supply of the electric cooker is stopped immediately. In this way, when any of the electrical components inserted in any pair of jacks is overloaded, immediately 9 M418467 stops the power supply to the overloaded jacks to prevent possible disasters; and solves the problem of the conventional safety sockets in each pair. When the lower rated electric device that the hole is inserted is overloaded, the non-sparkling switch with higher rated current on the socket body fails to immediately power off. & This new type of Besch mode adjustable over-current power-off protection socket can be adjusted according to the load of the electrical components inserted in the sockets of the socket: the respective rated current values of the holes, when any pair of them are plugged The electricity inserted in the hole
