INVENTION 1. Field of the Invention The present invention relates to an AC cord fall-off preventing device for preventing an AC cord plug inserted into an AC outlet such as a communication device or a personal computer from being accidentally dropped from an AC outlet. [Prior Art] Most of the connectors used in communication devices or personal computers are equipped with a connector anti-shedding device to prevent the electric plug inserted into the connector from falling out during use. Objects form a group. However, since some of the connectors are not provided with the anti-dropout device as described above, they are easily detached. Among such connectors, there is a combination of an AC outlet and an AC line for use in the input unit of the power supply unit. The AC cable, which is originally a cable inserted into an AC outlet, must be plugged into an AC outlet to prevent it from coming off easily. However, in reality, there is a disadvantage that the AC cable is easily detached from the AC outlet because there is no drop prevention mechanism. The screw-on AC power socket is equipped with a fixing screw to mount the AC outlet. The AC wire drop prevention device of the type in which the AC socket itself is attached to the device body while being fixed to the device body or attached to the screw body has been proposed (for example, see Patent Document). The non-screw type (inserted type) AC power socket has no fixing screws that are inevitable in order to fix the AC wire drop prevention tool, and the above-mentioned AC wire drop prevention can not be used, because the soil is selected to be inserted in a state stronger than 201110479. The AC wire prevents the AC wire from falling off, but there is a fear of a problem of solidity. 'The infrastructure device that requires reliability is a major problem. Patent Document 1: Japanese Unexamined Patent Publication No. Hei No. Hei No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. One is that when the non-screw type or plug-in type AC outlet is used due to the allowable construction area of the AC outlet, there is no space in the vicinity, so it is not possible to fix the AC line. It is difficult to achieve an effective countermeasure against the disconnection of the AC line by re-preparing the screw fixing portion with the falling prevention tool. Therefore, when the limitation of the construction area is prioritized, there are still many devices that are manufactured and used without the possibility of the disconnection of the AC wire and the potential danger of the AC wire drop accident. The present invention has been made in view of the above problems, and an object thereof is to provide an AC wire drop prevention device capable of: (1) designing a structure in which an AC wire drop prevention device is fixed to an AC outlet without a fixing screw, thereby even inserting a fixed type The AC power outlet can also prevent the disconnection of the AC power cord, and (2) the present invention has been manufactured and operated without the AC wire drop prevention tool because there is still no AC wire drop prevention tool for inserting the fixed AC outlet. In many of the devices, the package can be added without disassembling the main unit or removing the AC outlet. In order to achieve the above object, the AC wire fall-off preventing device of the present invention is inserted into an AC wire of a socket mounted in a recess of the main body to be detached from the socket, and is characterized in that it has: (1) Mounting device, mounted on a peripheral portion of the opening of the body recess; and (2) a fixture for fixing the mounting member and the AC wire. Here, the attachment member may be composed of four rectangular plate-like members which are protruded from the peripheral edge portion of the opening and whose adjacent sides are connected to each other; (4) among the plate-shaped members A poorly formed form has a locking fixture (5) that is mounted with a concave portion located therein. The pair of inserts are inserted into the gap between the peripheral members of the peripheral portion of the body surface and are fixed. The fixture may also have: the end is locked to the mounting device, and (6) two locking rods The direction of the long side - the other end of the long side direction is formed with two end portions of the thread formed with an insertion hole inserted at the end for pressing the pressing metal to the metal member of the (7) , in the direction of the long side, the other side of the two locking rods, the other AC wire is pressed against the socket; and (8) the knob-shaped screw is screwed into the screw, the socket is pressed, and The locking bar may be formed in a hole that is formed in the plate-like member with the anti-separation device attached to the attachment end (10)) at the through end, and the fixture may be provided with: 201110479 (π) resin binding strap; and (12) metal wire fixture formed in a central portion of the plug shoulder at a central portion in the longitudinal direction thereof, and for the bundle to pass through the long side thereof Both of the bent portions at both ends of the direction; (13) The mounting member is formed with an angular hole through which the binding band passes. Further, the term "socket according to the present invention" means a connector for an AC power input portion, which is generally referred to as an iron plate hole (concave portion) attached to a body device (e.g., a power supply unit or the like). The connector for the AC power output unit, i.e., the AC outlet, is also effective for the present invention. In the AC electric wire fall-off preventing device of the present invention, the mounting tool is attached to the peripheral edge portion of the opening of the main body recess by the insertion side of the mounting member inserted between the main body portion and the AC electric socket, and the mounting tool and the AC electric wire are fixed by the fixing device. . Therefore, the AC electric wire can be surely fixed to the socket even if the socket is fixed to the electronic device body without using a fixing screw. In this case, it is not necessary to add a new mounting area to the socket, that is, it can be additionally installed in the installed device. The mounting tool can be detached from the socket without the AC cord being attached to the socket, but it is safe to be disassembled when the AC cord is inserted into the socket. Moreover, the manufacturability of the fixture can be improved by making the fixture into a thin plate (made of metal or resin). [Embodiment] The present invention can realize an AC electric wire detachment preventing device which is used when a plug to which an AC electric wire is connected is inserted into a socket in which a recess of a main body of an electronic device is embedded and fixed. 6 201110479 [Embodiment] An embodiment of the present invention will be described with reference to Figs. 1 to 6 .

When the AC wire detachment preventing device 1 using the fixing tool 180 is set to the socket 2 〇 (refer to _ 3), the plug 4G of the AC wire 4! is first inserted into the socket 2 ( ), the central portion 192 of the curved metal wire portion (10) is suspended from the shoulder portion 42 of the plug wire 4 of the AC electric wire 41, and the bundling band 182 is passed through the hole (10) at both ends in the longitudinal direction thereof. Step: The band 182 passes through the corner hole 31c and is strongly tightened as shown in FIG. Therefore, the plug of the AC electric wire 4 照 照 照 照 照 照 插座 ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( 交流 交流 交流 交流 交流 交流It is also possible to install a fixed-type AC socket with a mounting bracket. This point is the same as that of the embodiment 2, and can also replace the wire fixing device 19〇 shown in Fig. 9, using the bending of the fixture shown in 201110479 1 〇 a metal wire portion. The bent metal wire portion 1 90'' of the fixture has no hole 19〇a formed at both end portions in the longitudinal direction thereof, and the arm 190a' may be formed instead of the hole 190a, and the band 182 may be suspended. In the configuration of the arm 1 90a, even in this manner, the same effect as that of Fig. 9 can be obtained. The body device using the screw-type AC outlet also has an unequipped AC wire drop prevention device. When the AC wire is detached, the fixing screw must be temporarily removed completely. This is because the installed device cannot be accommodated. However, by using the above-mentioned mounting tool (the opening is also formed in the plate member 32). )) The screw can be loosened only when the fixing screw is removed, so that the mounting tool can be additionally attached to the screw-mounted AC power socket.
