Description

  The present invention relates to an AC cord drop prevention tool for preventing an AC cord plug inserted into an AC inlet of a communication device or a personal computer from being accidentally dropped from an AC inlet or outlet.

  Many connectors used in electronic equipment such as communication equipment, measuring equipment, medical equipment, and personal computers are connected to the mating connector in the connector itself so that the cable inserted into the connector is not accidentally disconnected during use. Equipped with a pair of connectors. Such a connector is considered so that the connector does not come off during use and trouble does not occur. However, some connectors are not equipped with the above-described recesses, and some connectors are easy to disconnect. Among such connectors, there is a combination of an AC inlet or outlet and an AC cord used for an input / output unit of a power supply unit.

  Originally, the AC cord, which is a cable with a plug inserted into the AC inlet or outlet, is required to be securely inserted into the AC inlet or outlet and not easily fall off. Since there is no drop-off prevention mechanism, there is a drawback that the AC cord is easily dropped from the AC inlet or outlet.

  There has been devised and proposed an AC cord drop-off prevention tool that can prevent the AC cord from dropping by being attached to such an AC inlet or outlet (see, for example, Patent Documents 1 to 4).

  These AC cord drop-off prevention tools are used to fasten part of the drop-off prevention tool with a fixing screw for fixing the AC inlet or outlet to the apparatus, or to insert a part of the drop-off prevention tool between the AC inlet or outlet and the apparatus. The AC cord drop-off prevention device is attached to the AC inlet or outlet. However, in order to emphasize the appearance of the device, the AC inlet or outlet is covered with a decorative board, or the AC plug of the AC inlet or outlet is inserted. There is an apparatus in which an opening that exposes only the peripheral part of the recess is provided and the apparatus is fixed to the inside of the main body housing so that only the peripheral part of the AC inlet or outlet AC plug is exposed. The one using the main unit can operate other than the AC inlet or outlet. In some cases the purpose of preventing the risk of such reduced reliability and operation errors Jill device. When the periphery of such an AC inlet or outlet is covered with a decorative plate or the outer peripheral material of the housing of the main unit, the conventional AC cord drop prevention tool and the AC inlet or outlet cannot be captured each other, and the AC cord drop prevention tool is used. Cannot be installed. In such a case, there are some devices that are equipped with anti-drop-off tools using adhesive tape on the top and bottom or left and right sides of the device perpendicular to the mounting surface of the AC inlet or outlet, but the adhesive tape is reliable for permanent mounting. At the same time, there is a problem that the adhesive tape is rubbed and peeled off or damaged when the apparatus is mounted in a plurality of stages on a rack or when the housing is taken in and out using a slide rail.

  In these cases, an AC cord that is hard to insert is selected to prevent the AC cord from falling off. However, there is a problem with certainty, and manufacturing equipment that requires reliability, such as infrastructure equipment and medical equipment. It has become a big problem with devices.

  There are two methods for fixing the AC inlet or outlet to the device: a screw fixing type and a non-screw fixing insertion fixing type. The AC inlet or outlet is covered with a decorative plate or a casing outer peripheral material of the main unit. In this case, the AC inlet or outlet fixing screw and the gap between the AC inlet or outlet and the slight contact portion formed by the device are generally covered with the decorative plate and the casing outer peripheral material of the main body device, so that the conventional AC cord is prevented from falling off. In any fixed type, the mounting tool for mounting itself on the AC inlet or outlet cannot directly capture the AC inlet or outlet.

  In addition, in the case where the appearance is emphasized in the device in which the periphery of the AC inlet or outlet is covered with the decorative plate or the casing outer peripheral material of the main body device, the addition of screws is not allowed easily, and the case where safety and reliability are important is similarly applied. The addition of a screw is not preferable, and in the conventional AC cord drop prevention tool, the mounting tool for mounting itself on the AC inlet or outlet cannot capture the AC inlet or outlet. Furthermore, it is not known what kind of device exists under the decorative plate or the outer peripheral material of the housing of the main unit, and there is a risk of chips entering the device by drilling to use new screws for mounting etc. In some cases, it is not preferable, and the manufacturer's warranty may be terminated due to the processing of the equipment. Therefore, it is impossible to inadvertently add new screw holes for mounting the AC cord fall-off prevention tool, realizing an effective AC cord fall-out prevention measure. Have difficulty.

  Furthermore, if a fall prevention device is attached using adhesive tape to a device in which the periphery of the AC inlet or outlet is covered with a decorative board or outer peripheral material of the casing, there is a problem that the permanent deterioration cannot be secured and the permanentity cannot be secured. It cannot be used when reliability is required.

  According to the present invention, an AC plug to which an AC cable is connected is inserted into an AC inlet or outlet covered with a decorative plate or a casing outer peripheral material of the main body device and fixed around the main body recessed portion of the electronic device. It was realized in the AC cord dropout prevention tool used sometimes.

  Note that the AC cord drop prevention device of the present invention can be attached to the AC inlet and the outlet in exactly the same manner. Therefore, in the description of the embodiment, description on the AC inlet is omitted, and the description using the AC outlet is omitted in the following description. Outlet is simply described as inlet.

  A first embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 shows a mounting state of a non-screw-fixed insertion-fixed inlet whose periphery is covered with a decorative board to a device before application of the present invention, (A) is a perspective view thereof, and (B) is a perspective view thereof. It is sectional drawing. FIG. 2 shows the mounting state of the screw-fixed inlet, the periphery of which is covered with a decorative board, to the device before application of the present invention, (A) is a perspective view thereof, and (B) is a sectional view thereof.

  From FIGS. 1A and 1B and FIGS. 2A and 2B, the peripheral portion 20b of the recessed portion 20a on which the electrode 21 of the inlet 20 into which the plug portion 40 of the AC cord is inserted is mounted on the decorative board 13 Inlet fixing screws 22a and 22b that are exposed from the provided opening 15 but are used to attach a conventional AC cord drop-off prevention tool together or an insertion piece for insertion are inserted. It can be seen that the existing AC cord drop-off prevention device cannot be mounted because the contact portion between the lower edge of the inlet peripheral portion 20b and the opening peripheral portion 12b of the apparatus in which the inlet 20 is mounted is not exposed. Further, the exposed peripheral edge portion 20b of the inlet 20 and the opening 15 of the decorative plate 13 covering the periphery of the inlet are made to have substantially the same size and shape, but in practice, the decorative plate 13 is intended to easily cover the inlet 20 with the decorative plate 13. The opening 15 is usually designed with a small but sufficient dimension margin. As a result, there is a gap 13d between the inlet 20 and the edge 13b of the opening 15 of the decorative board 13. .

  FIG. 3 (A) is a perspective view showing a process of mounting the mounting tool 30 of the present invention on the device 12 mounted with the inlet 20 covered with the decorative board 13, and FIG. 3 (B) is after the above process is completed. It is a perspective view which shows the state of the mounting tool 30 in which mounting | wearing was completed.

  4 (A) and 4 (B) are mounted in a gap 13d due to a dimensional margin between the inlet 20 mounted on the apparatus 12 and the decorative plate 13 in the present invention, which is opposite to FIGS. 1 (B) and 2 (B), respectively. FIG. 6 is a cross-sectional view showing a state in which the mounting tool 30 of the AC cord dropout prevention tool fixed to the inlet 20 by a sandwiching piece 35;

  FIG. 5 is a perspective view showing a usage form of the AC cord drop-off preventing device of the present invention in which the AC plug 40 is fixed to the inlet 20 by combining the mounting device 30 of the present invention with a simple and general wire fixing device 100. .

  In order to fix the AC cord plug 40 to the inlet 20 and prevent the AC cord from falling off, the AC plug 40 is first removed from the inlet 20, the screw 14 is removed, and the decorative plate 13 is mounted on the inlet 12. Remove from. Next, the attachment tool 30 of the present invention is fitted into the peripheral portion 12c of the peripheral edge portion 12b of the inlet 20 so as to be in close contact and temporarily attached to the inlet 20, and the plate-like rectangular surface 31 of the attachment tool 30 is inserted into the opening portion 15. The decorative board 13 that has passed through 32, 33, and 34 is put on the periphery of the inlet 20, and the screw 14 is tightened back to fix the mounting tool 30 to the inlet 20. Subsequently, the AC plug 40 is inserted into the concave portion 20a of the inlet 20, the center portion of the fixture 100 is hung on the shoulder portion 42 of the AC plug 40, and the bent portions 100b and 100b at the ends of the leg portions 100a and 100a are connected to the inlet 20 respectively. The AC cord to which the AC plug 40 is connected is pressed from the inlet by the fixture 100 pressing the AC plug 40 toward the inlet by passing through the fixing device locking round holes 31a and 33a of the mounting tool 30 while pulling the AC cord 40 toward the inlet. Can be prevented from falling off.

  Here, the wire-made fixture 100 is preferably made of stainless steel or steel wire having a strength that does not easily deform, and a bent portion 100b bent outward at the tip of each leg portion 100a, 100a at both ends in the longitudinal direction. , 100b. The distance between the leg portions 100a, 100a at both ends of the fixing device 100 is formed in advance so as to be wider than the interval between the locking round holes 31a, 33a of the mounting device 30, so that the bent portions 100b at the tips of both legs 100a, 100a are formed. , 100b is inserted into the locking holes 31a, 33a of the mounting tool 30, respectively, so that the fixing tool 100 is securely coupled to the mounting tool 30.

  Next, with reference to FIG. 6 (A) and FIG. 6 (B), Example 2 of the AC cord drop-off preventing device of the present invention will be described. The fixing device 100 combined with the mounting device 30 is obtained by adding the improvement of the bending angle of the bent portion to the fixing device described in the first embodiment of the present invention.

  FIG. 6A is a perspective view showing a usage form of the AC cord dropout prevention device of the present invention, which is composed of the mounting device 30 divided into the mounting elements 30a and 30b and the fixing device 100 to which the AC cord plug 40 is fixed. FIG. 6B is a perspective view showing details of the mounting tool 30 by the mounting element 30a and the mounting element 30b divided into two parts. In these drawings, the same components as those shown in FIGS. 1 to 5 are denoted by the same reference numerals.

  In order to fix the AC cord plug 40 to the inlet 20 and prevent the AC cord from falling off, first remove the AC plug 40 from the inlet, remove one end of the screw 14 and remove the decorative plate 13 from the main body. The two open ends of the elements 30a and 30b are opposed to each other, and are temporarily attached to the peripheral portion 20c of the inlet 20 so as to be temporarily attached to the main body. Next, the decorative plate 13 is covered with the inlet 20 on which the mounting tool 30 is temporarily mounted so that the opening 15 of the decorative plate 13 penetrates the plate-like rectangular surfaces 31, 32 a, 32 b, 33, 34 b, 34 a of the mounting tool 30. Then, the screw 14 is tightened and the mounting tool 30 is fully mounted, and then the AC plug 40 is inserted back into the inlet 20.

  Subsequently, the bent portions 100b and 100b provided at the tips of the leg portions 100a and 100a at both ends in the longitudinal direction of the fixture 100 are inserted into the locking holes 31a and 33a for fixing the fixture of the mounting device 30, and then Since the central portion 100c of the fixture 100 is raised and pulled away from the inlet 20, the fixture 100 presses the AC plug 40 toward the inlet 20 by hooking it on the shoulder portion 42 of the AC cord plug 40. The AC cord to which 40 is connected can be prevented from falling off the inlet 20 without any processing on the decorative board.

  When the mounting elements 30a and 30b obtained by dividing the mounting tool 30 are mounted on the inlet 20 with the same shape and size, the plate-like rectangular surfaces 32b and 32b and 34a and 34b are designed to have a space between them. Therefore, the plate-like rectangular surfaces 31 and 33 can be brought into close contact with or substantially in close contact with the inlet 20 having different dimensions, and the mounting tool 30 is preferably made of a thin metal plate having a thickness of about 0.5 mm. Thus, the mounting tool 30 can be mounted using a slight gap 13d due to a dimension allowance that is taken into consideration when the decorative plate opening 15 between the decorative plate 13 and the inlet 20 is designed, and further, the skirt portion of the plate-shaped rectangular surface. Since the sandwiching part that stands up vertically is designed to have a size that cannot pass through the gap 13d, the decorative board 13 and the device 12 are mounted without any processing. 30 can be securely fixed to the inlet 20, so that dropping of the AC cord can be prevented.

  At the same time, the mounting tool 30 of the present invention has a simple structure that can be manufactured by punching and bending a thin metal plate, and can be manufactured at low cost.

  Here, the fixture 100 is preferably made of a stainless steel or steel wire having a strength that does not easily deform, and is formed into a substantially U shape by a central portion and a side portion 100d bent at a right angle adjacent to the longitudinal direction. The molded plug supplement part holds the cord plug part 41 of the AC plug 40 so as to surround the cord plug part 41 and presses the shoulder part 42 of the AC plug. Further, the protruding parts 100e adjacent to each other in the longitudinal direction of the side part 100d are once perpendicular to each other. It is bent toward the outside and further bent in the inlet direction at a right angle to reach the leg portions 100a and 100a, and bent portions 100b and 100b are provided at the ends thereof. Since the distance between the leg portions 100a and 100a at both ends of the fixture 100 is previously formed wider than the interval between the locking round holes 31a and 33a of the mounting tool 30, the bent portions 100b at the tips of both legs 100a and 100a, The fixing tool 100 is securely coupled to the mounting tool 30 simply by inserting 100b into the locking holes 31a and 33a of the mounting tool 30, respectively. Further, the angle between the U-shaped portion of the fixture 100 and the legs 100a and 100a when the pressing portion is viewed from the leg 100a side is slightly sharper than a right angle, preferably 80 to 85 degrees. 40 is convenient because it is appropriately pressed against the inlet by the pressing portion of the fixture.

  Next, with reference to FIG. 7 (A) and FIG. 7 (B), Example 3 of the AC cord drop-off preventing device of the present invention will be described. The fixture 100 combined with the mounting tool 30 is the same as the fixture described in the second embodiment of the present invention.

  FIG. 7A is a perspective view showing a usage form of the AC cord drop-off preventing device of the present invention, which is composed of the mounting device 30 divided into the mounting elements 30a and 30b and the fixing device 100 to which the AC cord plug 40 is fixed. FIG. 7B is a perspective view showing details of the mounting tool 30 by the mounting element 30a and the mounting element 30b divided into two parts. In these drawings, the same components as those shown in FIGS. 1 to 5 are denoted by the same reference numerals.

  In order to fix the AC cord plug 40 to the inlet 20 and prevent the AC cord from falling off, the AC plug 40 is first removed from the inlet, the screw 14 is removed at one end, and the decorative plate 13 is removed from the main body 12. Subsequently, the open ends of the two mounting elements 30a and 30b are opposed to each other so as to surround the peripheral portion 20c of the inlet 20 and the serrated engagement portions 35a21 and 35b31 of both mounting elements and 32a and 32b in FIG. 7B. 35a31 and 35b21 are fixed to the inlet mounted on the device 12 by pressing the mounting elements 30a and 30b against the decorative plate 13 by the sandwiching pieces 35a1, 35a2, 35a3, 35b1, 35b2, and 35b3, respectively. While being engaged so as to maintain the mutual connection until it is done, it is brought into close contact with the peripheral portion 20c of the inlet 20 or is temporarily attached. Next, the decorative plate 13 is covered with the inlet 20 on which the mounting tool 30 is temporarily mounted so that the opening 15 of the decorative plate 13 penetrates the plate-like rectangular surfaces 31, 32 a, 32 b, 33, 34 b, 34 a of the mounting tool 30. Then, the screw 14 is tightened and the mounting tool 30 is fully mounted, and then the AC plug 40 is inserted back into the inlet 20.

Subsequently, the bent portions 100b and 100b provided at the ends of the leg portions 100a and 100a at both ends in the longitudinal direction of the fixture 100 are inserted into the fixing device locking round holes 31a and 33a of the mounting device 30, and then fixed. The fixing device 100 presses the AC plug 40 toward the inlet 20 by hooking the shoulder portion 42 of the AC cord plug 40 while raising the central portion 100c of the tool 100 and pulling it away from the inlet 20, so that the AC plug 40 The AC cord connected to can be prevented from falling off the inlet 20 without any processing on the decorative board.

  The two mounting elements 30a and 30b that divide the mounting tool 30 are designed to have dimensions that allow space between the plate-like rectangular surfaces 32a and 32b and 34a and 34b when mounted on the inlet 20 with the same shape and dimensions. Accordingly, the plate-like rectangular surfaces 31 and 33 can be brought into close contact or almost tight contact with the inlet 20 having different dimensions, and the mounting tool 30 is preferably made of a thin metal plate having a plate thickness of about 0.5 mm. By doing so, the mounting tool 30 can be mounted using the slight gap 13d due to the dimension allowance considered at the time of designing the decorative plate opening 15 between the decorative plate 13 and the inlet 20, and the hem of the plate-like rectangular surface Since the sandwiched portion that rises perpendicularly to the outside of the unit is designed to have a size that cannot pass through the gap 13d, the decorative plate 13 and the device 12 are not processed at all. The Chakugu 30 can be fixed to the inlet 20 can be prevented from falling off the resulting AC cord.

  Further, the mounting tool 30 is provided with trapezoidal overhanging portions 31c and 33c in the opposite direction of the sandwiched portion at the center of each of the plate-like rectangular surfaces 31 and 33, and both sides thereof are perpendicular to the inside from the rectangular surface. When the bending portion is provided as the reinforcing portions 31d, 31d, 33d, and 33d and the mounting tool is made of a thin metal plate, the tensile force received from the fixing tool is sandwiched between the entire pieces 35a1 and 35b1, and the rectangular surface 31, By strengthening 33 to prevent distortion, it is possible to prevent the AC cord from falling off more reliably.

  Here, the fixture 100 is preferably made of a stainless steel or steel wire having a strength that does not easily deform, and is formed into a substantially U shape by a central portion and a side portion 100d bent at a right angle adjacent to the longitudinal direction. The shoulder portion 42 of the AC plug is pressed while being caught so as to surround the cord lead portion 41 of the molded AC plug 40, and the protruding portions 100e adjacent to each other in the longitudinal direction of the side portion 100d are once directed outward at a right angle. It is bent and further bent at right angles in the inlet direction to reach the leg portions 100a and 100a, and bent portions 100b and 100b are provided at the ends thereof. Since the distance between the leg portions 100a, 100a at both ends of the fixture 100 is previously formed wider than the interval between the locking round holes 31a, 33a of the mounting tool 30, the bent portion 100b at the tip of both legs 100a, 100a. , 100b is inserted into the locking holes 31a, 33a of the mounting tool 30, respectively, so that the fixing tool 100 is securely coupled to the mounting tool 30.

  In addition, the angle between the part of the fixing tool 100 on the shoulder of the AC plug and the legs 100a and 100a when the pressing part is viewed from the leg 100a side is formed to be slightly acute, preferably 80 to 85 degrees. The AC plug 40 can be conveniently stopped at the inlet, which is convenient.

  Next, with reference to FIG. 8 (A) and FIG. 8 (B), Example 4 of the AC cord drop prevention device of the present invention will be described.

  FIG. 8A is a perspective view showing a usage form of the AC cord drop-off preventing device of the present invention, which is composed of the mounting device 30 divided into the mounting elements 30a and 30b and the fixing device 100 to which the AC cord plug 40 is fixed. FIG. 8B is a perspective view showing details of the mounting tool 30 by the mounting element 30a and the mounting element 30b divided into two parts. In these drawings, the same components as those shown in FIGS. 1 to 5 are denoted by the same reference numerals.

  In order to fix the AC cord plug 40 to the inlet 20 and prevent the AC cord from falling off, the AC plug 40 is first removed from the inlet, the screw 14 is removed at one end, and the decorative plate 13 is removed from the main body. Subsequently, the open ends of the two mounting elements 30a and 30b in the longitudinal direction face each other so as to surround the peripheral portion 20c of the inlet 20 and the serrated engagement portions 35a21 and 35b31 of the both mounting elements as well as 32a and 32b in FIG. 8B. 35a31 and 35b21 are fixed to the inlet mounted on the device 12 by pressing the mounting elements 30a and 30b against the decorative plate 13 by the sandwiching pieces 35a1, 35a2, 35a3, 35b1, 35b2, and 35b3, respectively. While being engaged so as to maintain the mutual connection until it is done, it is brought into close contact with the peripheral portion 20c of the inlet 20 or is temporarily attached. Next, the decorative plate 13 is covered with the inlet 20 on which the mounting tool 30 is temporarily mounted so that the opening 15 of the decorative plate 13 penetrates the plate-like rectangular surfaces 31, 32 a, 32 b, 33, 34 b, 34 a of the mounting tool 30. Then, the screw 14 is tightened and the mounting tool 30 is fully mounted, and then the AC plug 40 is inserted back into the inlet 20.

Subsequently, two tie wraps are used as locking synthetic resin tying strings 180, each of which is preferably a square for locking provided on the protruding portions of the plate-like rectangular surfaces 31 and 33 facing each other of the mounting tool 30. A loop is loosely formed by passing the tip of the bundling string 180 through the hole and through the detent feed section 180b in which the detent is incorporated. Subsequently, the base portion of the AC cord 41 of the AC plug 40 is surrounded by a plug capturing portion formed in a substantially U shape by a side portion 190d bent at a right angle adjacent to the central portion 190c of the pressing metal 190 in the longitudinal direction. Placed on the shoulder portion 42 of the AC plug, the arms 190a, 190a provided with the respective longitudinally extending portions of the plug catching portion are hung with the above-mentioned loosely looped synthetic resin binding cord 180, and each is tied evenly. The fastener 100 presses the AC plug 40 toward the inlet 20 by sending 180a and tightening the ring, so that the AC cord to which the AC plug 40 is connected falls off the inlet 20 without any processing on the decorative plate. Can be prevented.

  The two mounting elements 30a and 30b that divide the mounting tool 30 are designed to have dimensions that allow space between the plate-like rectangular surfaces 32a and 32b and 34a and 34b when mounted on the inlet 20 with the same shape and dimensions. Accordingly, the plate-like rectangular surfaces 31 and 33 can be brought into close contact with or substantially in close contact with the inlet 20 having different dimensions, and preferably made of a thin metal plate having a thickness of about 0.5 millimeters after mounting. Thus, the mounting tool 30 can be mounted using a slight gap 13d due to a dimension allowance that is taken into consideration when the decorative plate opening 15 between the decorative plate 13 and the inlet 20 is designed, and further, the skirt portion of the plate-shaped rectangular surface. The sandwiched part that stands vertically outside is designed to have a size that cannot pass through the gap 13d, so that the decorative board 13 and the device 12 are mounted without being processed at all. 30 can be fixed to the inlet 20 can be prevented from falling off the resulting AC cord.

  Further, the mounting tool 30 is provided with trapezoidal overhanging portions 31c and 33c in the opposite direction of the sandwiched portion at the center of each of the plate-like rectangular surfaces 31 and 33, and both sides thereof are perpendicular to the inside from the rectangular surface. When the bending portion is provided as the reinforcing portions 31d, 31d, 33d, and 33d and the mounting tool is made of a thin metal plate, the tensile force received from the fixing tool is sandwiched between the entire pieces 35a1 and 35b1, and the rectangular surface 31, By strengthening 33 to prevent distortion, it is possible to prevent the AC cord from falling off more reliably.

  The pressing metal 190 is preferably made of a stainless steel or steel wire having a diameter of 2φ or more and has a strength that does not easily deform. The pressing metal 190 is formed by a central portion 190c adjacent to each side portion 190d bent at a right angle. A U-shaped plug catching portion is formed, and the extension portion is once bent at right angles on both outer sides of the U-shape to form projecting portions 190e and 190e, and further 80 to 85 degrees with respect to the horizontal catching portion. To the vertical joints 190f and 190f, and further bent at a right angle to form arms 190a and 190a substantially parallel to the side 190d, and a bent portion is formed with the tip bent upward at a right angle. Has been.

  The plug capturing part reliably captures the plug 40 with such a size that the base part 41 of the plug of the AC cord can be deeply surrounded from three directions. Further, the side part 190d and the arm part 190a reciprocate beyond the center of the plug 40, and the arm part 190a of the pressing metal 190 acts as a lever with the connecting part of the side part 190d and the projecting part 190e as a fulcrum. At the same time, due to the structure of the side portion 190d and the vertical connecting portion 190f that make the mutual angle acute, when the arm portion 190a is pressed in the direction of the inlet 40 with a strong force, the entire catching portion is more reliably pressed against the shoulder portion 42 of the plug. . At the same time, since both ends of the arm portion 190a are bent upward, the binding string locked to the arm portion 190a is stably locked without falling off the arm portion 190a.

  Next, with reference to FIG. 9 (A) and FIG. 9 (B), Example 5 of the AC cord drop-off preventing device of the present invention will be described. The mounting tool 30 is the same as the mounting tool described in the fourth embodiment of the present invention.

  FIG. 9A is a perspective view showing a usage form of the AC cord drop-off preventing device of the present invention, which is composed of the mounting device 30 divided into the mounting elements 30a and 30b and the fixing device 100 to which the AC cord plug 40 is fixed. FIG. 9 (B) is a diagram showing a synthetic resin closure fastener 185a on a flat plate, and FIG. 9 (C) is a drawing showing a synthetic resin detent feeder 185b of a fastener. In these drawings, the same components as those shown in FIGS. 1 to 5 are denoted by the same reference numerals.

  In order to fix the AC cord plug 40 to the inlet 20 and prevent the AC cord from falling off, the AC plug 40 is first removed from the inlet, the screw 14 is removed at one end, and the decorative plate 13 is removed from the main body. Subsequently, the open ends of the two mounting elements 30a and 30b are opposed to each other so as to surround the peripheral portion 20c of the inlet 20, and the serrated engagement portions 35a21 and 35b31 and 35a31 and 35b21 of the both mounting elements are sandwiched, respectively. 35a1, 35a2, 35a3, 35b1, 35b2, and 35b3 are engaged so that the mounting elements 30a and 30b are pressed against the decorative board 13 and fixed to the inlet mounted on the device 12 so as to maintain mutual connection. Temporarily attached to the peripheral portion 20c in close contact with or substantially in close contact. Next, the decorative plate 13 is covered with the inlet 20 on which the mounting tool 30 is temporarily mounted so that the opening 15 of the decorative plate 13 penetrates the plate-like rectangular surfaces 31, 32 a, 32 b, 33, 34 b, 34 a of the mounting tool 30. Then, the screw 14 is tightened and the mounting tool 30 is fully mounted, and then the AC plug 40 is inserted back into the inlet 20.

  Subsequently, each of the two flat plate-like locking strings 185a constituting the synthetic resin fastener 185 is used for locking provided on the protruding portions of the respective plate-like rectangular surfaces 31 and 33 facing the mounting tool 30. Preferably, it is inserted into the square locking hole until it stops at the retaining portion 185a2. Subsequently, the base portion of the AC cord 41 of the AC plug 40 is surrounded by a plug capturing portion formed in a substantially U shape by a side portion 190d bent at a right angle adjacent to the central portion 190c of the pressing metal 190 in the longitudinal direction. Insert the tip of the flat-shaped locking string 185a into the feeding tool 185b with a detent mounted on the shoulder part 42 of the AC plug 190a, and press each of the locking strings 185a evenly. The fastener 100 presses the AC plug 40 toward the inlet 20 by tightening the metal fitting 190 to the shoulder portion 42 of the AC plug, so that the AC cord to which the AC plug 40 is connected is the device 12 or the decorative plate on which the inlet is mounted. 13 can be prevented from falling off the inlet 20 without any processing.

  The two mounting elements 30a and 30b that divide the mounting tool 30 are designed to have dimensions that allow space between the plate-like rectangular surfaces 32a and 32b and 34a and 34b when mounted on the inlet 20 with the same shape and dimensions. Therefore, the plate-like rectangular surfaces 31 and 33 can be brought into close contact or almost tight contact with the inlet 20 having different dimensions, and the attachment is preferably made of a thin metal plate of about 0.5 mm. The tool 30 can be mounted using a slight gap 13d due to the dimension allowance considered at the time of designing the decorative plate opening 15 between the decorative plate 13 and the inlet 20, and further perpendicular to the bottom of the plate-like rectangular surface. Since the sandwiched portion that has risen is designed to have a size that cannot pass through the gap 13d, the decorative plate 13 and the device 12 are not processed at all, and the mounting tool 30 is inserted. It can be fixed to let 20 can be prevented from falling off the resulting AC cord.

  Further, the mounting tool 30 is provided with trapezoidal overhanging portions 31c and 33c in the opposite direction of the sandwiched portion at the center of each of the plate-like rectangular surfaces 31 and 33, and both sides thereof are perpendicular to the inside from the rectangular surface. When the bending portion is provided as the reinforcing portions 31d, 31d, 33d, and 33d and the mounting tool is made of a thin metal plate, the tensile force received from the fixing tool is sandwiched between the entire pieces 35a1 and 35b1, and the rectangular surface 31, By strengthening 33 to prevent distortion, the AC cord was more reliably dropped.

  The pressing metal 190 is preferably made of a stainless steel or steel wire having a diameter of 2φ or more and has a strength that does not easily deform. The pressing metal 190 is formed by a central portion 190c adjacent to each side portion 190d bent at a right angle. A U-shaped plug catching portion is formed, and the extension portion is once bent at right angles on both outer sides of the U-shape to form projecting portions 190e and 190e, and further 80 to 85 degrees with respect to the horizontal catching portion. To the vertical joints 190f, 190f downward at an angle of, and further bent at a right angle to form arms 190a, 190a substantially parallel to the side 190d, with their tips bent at a right angle upward. Bent part is formed

The plug capturing part reliably captures the plug 40 with such a size that the base part 41 of the plug of the AC cord can be deeply surrounded from three directions. Further, the side part 190d and the arm part 190a reciprocate beyond the center of the plug 40, and the arm part 190a of the pressing metal 190 acts as a lever with the connecting part of the side part 190d and the projecting part 190e as a fulcrum. At the same time, due to the structure of the side portion 190d and the vertical connecting portion 190f that make the mutual angle acute, when the arm portion 190a is pressed in the direction of the inlet 40 with a strong force, the entire catching portion is more reliably pressed against the shoulder portion 42 of the plug. . At the same time, the leg portion 190f and the bent portion 190b are formed in parallel so that the feeding device with the detent can be fitted conveniently.

  Next, with reference to FIG. 7B of Example 3 in addition to FIG. 10A and FIG. 10B, Example 6 of the AC cord drop prevention device of the present invention will be described. The mounting tool 30 is the same as the mounting tool described in the third embodiment of the present invention.

  FIG. 10A is a perspective view showing a usage form of the AC cord drop-off preventing device of the present invention constituted by the mounting device 30 divided into the mounting elements 30a and 30b and the fixing device 100 to which the AC cord plug 40 is fixed. FIG. 10B is an exploded perspective view of the fixture 100. In these drawings, the same components as those shown in FIGS. 1 to 5 are denoted by the same reference numerals.

  In order to fix the AC cord plug 40 to the inlet 20 and prevent the AC cord from falling off, the AC plug 40 is first removed from the inlet, the screw 14 is removed at one end, and the decorative plate 13 is removed from the main body. Subsequently, the open ends of the two mounting elements 30a and 30b are opposed to each other so as to surround the peripheral portion 20c of the inlet 20, and the serrated engagement portions 35a21 and 35b31 and 35a31 and 35b21 of the both mounting elements are sandwiched, respectively. 35a1, 35a2, 35a3, 35b1, 35b2, and 35b3 are engaged so that the mounting elements 30a and 30b are pressed against the decorative board 13 and fixed to the inlet mounted on the device 12 so as to maintain mutual connection. Temporarily attached to the peripheral portion 20c in close contact with or substantially in close contact. Next, the decorative plate 13 is covered with the inlet 20 on which the mounting tool 30 is temporarily mounted so that the opening 15 of the decorative plate 13 penetrates the plate-like rectangular surfaces 31, 32 a, 32 b, 33, 34 b, 34 a of the mounting tool 30. Then, the screw 14 is tightened and the mounting tool 30 is fully mounted, and then the AC plug 40 is inserted back into the inlet 20.

  Subsequently, the bent portions 110b at one ends of the two bent rod-like locking rods 110 which are constituent elements of the fixing device 100 are inserted into the fixing device locking round holes 31a and 33a of the mounting device 30, respectively, and the E-rings are inserted. At 37, the locking rod 110 is prevented from falling off the mounting tool 30. Subsequently, the male threaded portion 110a at the other end of each of the bending rod-like locking rods 110 is passed through substantially annular hole receiving portions 190b1 provided at both ends in the longitudinal direction of the pressing metal 190, and along the internal axis. A cylindrical knob 130 having a female screw is screwed in.

  Subsequently, the fixing tool 100 is raised and the central portion 190c of the pressing metal 190 is hung on the shoulder 42 of the AC plug 40, and the two cylindrical knobs are turned to press the pressing metal 190 evenly toward the AC plug 40. The AC cord to which the AC plug 40 is connected can be prevented from falling off the inlet 20 without any processing on the device 12 or the decorative board 13 on which the inlet is mounted. When the shape and dimensions of the AC plug are different, the position of the pressing bracket can be changed over a wide range by turning the cylindrical knob.

  In this embodiment, when the length of the bent bar-shaped locking bar is about 30 mm and the length of the cylindrical knob is about 20 mm, the range in which the position of the pressing bracket can be changed by turning the cylindrical knob is approximately. Since it can be used for almost all general AC plugs marketed in about 20 millimeters, it is not necessary to manufacture a fixture for each plug, which is convenient. By increasing the length of the bent bar-like locking bar and the cylindrical knob, the range of change of the angle can be further increased.

  Further, when the mounting elements 30a and 30b obtained by dividing the mounting tool 30 are mounted on the inlet 30, the plate-like rectangular surfaces 31a, 32b and 34a are designed to have a space between them, so that the dimensions of the inlet 20 are the same. Even if they are different, the plate-like rectangular surfaces 31 and 33 can be brought into close or close contact with the inlet. Preferably, the mounting tool 30 is made of a thin metal plate having a thickness of about 0.5 mm so that the mounting tool 30 and the inlet 13 It can be mounted in a slight gap 13d due to a dimensional margin taken into account when designing the opening portion of the decorative plate between 20. Further, the sandwiching piece rising perpendicularly to the bottom of the plate-like rectangular surface cannot pass through the gap 13d. Since it is designed to have the possible dimensions, the mounting tool 30 can be fixed to the inlet 20 without any processing of the decorative board 13 or the device 12, and as a result, the AC cord Dropping can be prevented of.

  Further, the mounting tool 30 is provided with trapezoidal overhanging portions 31c and 33c in the opposite direction to the sandwiching portions of the central extension surfaces of the plate-like rectangular surfaces 31 and 33, and both sides thereof face inward from the rectangular surface. When the bent portions are provided as the reinforcing portions 31d, 31d, 33d, and 33d perpendicularly to the mounting member and the mounting tool is made of a thin metal plate, the tensile force received from the fixing tool is sandwiched between the entire pieces 35a1 and 35b1, and at the same time, the rectangular surface By strengthening 31 and 33 to prevent distortion, the AC cord was more reliably prevented from falling off.

  The pressing metal 190 is preferably made of a stainless steel or steel wire having a diameter of 2φ or more and has a strength that does not easily deform. The pressing metal 190 is formed by a central portion 190c adjacent to each side portion 190d bent at a right angle. A U-shaped plug catching portion is formed, and the extension portion is once bent at right angles on both outer sides of the U-shape to form projecting portions 190e and 190e, and further 80 to 85 degrees with respect to the horizontal catching portion. The arm portions 190a and 190a are formed substantially parallel to the side portion 190d by being bent at a right angle, and are provided with substantially annular holes at the tips thereof. Knob receiving portions 190b1 and 190b1 are provided.

  The plug capturing part reliably captures the plug 40 with such a size that the base part 41 of the plug of the AC cord can be deeply surrounded from three directions. Further, the side part 190d and the arm part 190a reciprocate beyond the center of the plug 40, and the arm part 190a of the pressing metal 190 acts as a lever with the connecting part of the side part 190d and the projecting part 190e as a fulcrum. At the same time, due to the structure of the side portion 190d and the vertical connecting portion 190f that make the mutual angle acute, when the arm portion 190a is pressed in the direction of the inlet 40 with a strong force, the entire catching portion is more reliably pressed against the shoulder portion 42 of the plug. .

  Next, with reference to FIG. 11 (A) and FIG. 11 (B), Example 6 of the AC cord drop-off preventing device of the present invention will be described. The mounting tool 30 is the same as the mounting tool described in the third embodiment of the present invention.

  FIG. 11A is a perspective view showing a usage form of the AC cord drop-off prevention device of the present invention constituted by the mounting device 30 divided into the mounting elements 30a and 30b and the fixing device 100 to which the AC cord plug 40 is fixed. FIG. 11B is an exploded perspective view of the fixture 100 of the present embodiment.

  The wearing tool 30 of the seventh embodiment is the same as the wearing tool of the third embodiment. Moreover, the plug pressing tool 200 which is an element constituting the fixing tool 100 is obtained by adding the hole knob receiving metal 120 to the pressing metal 190 of the fourth embodiment and sharing the pressing metal 190 with the sixth embodiment. In these drawings, the same components as those shown in FIGS. 1 to 5 are denoted by the same reference numerals.

  In order to fix the AC cord plug 40 to the inlet 20 and prevent the AC cord from falling off, the AC plug 40 is first removed from the inlet, the screw 14 is removed at one end, and the decorative plate 13 is removed from the main body. Subsequently, the open ends of the two mounting elements 30a and 30b are opposed to each other so as to surround the peripheral portion 20c of the inlet 20, and the serrated engagement portions 35a21 and 35b31 and 35a31 and 35b21 of the both mounting elements are sandwiched, respectively. 35a1, 35a2, 35a3, 35b1, 35b2, and 35b3 are engaged so that the mounting elements 30a and 30b are pressed against the decorative board 13 and fixed to the inlet mounted on the device 12 so as to maintain mutual connection. Temporarily attached to the peripheral portion 20c in close contact with or substantially in close contact. Next, the decorative plate 13 is covered with the inlet 20 on which the mounting tool 30 is temporarily mounted so that the opening 15 of the decorative plate 13 penetrates the plate-like rectangular surfaces 31, 32 a, 32 b, 33, 34 b, 34 a of the mounting tool 30. Then, the screw 14 is tightened and the mounting tool 30 is fully mounted, and then the AC plug 40 is inserted back into the inlet 20.

  Subsequently, the bent portions 110b at one ends of the two bent rod-like locking rods 110 which are constituent elements of the fixing device 100 are inserted into the fixing device locking round holes 31a and 33a of the mounting device 30, respectively, and the E-rings are inserted. At 37, the locking rod 110 is prevented from falling off the mounting tool 30. Subsequently, a pressing member in which a knob receiving member 120 with a hole is attached in advance so that the knob receiving piece 120b provided with a round hole is placed on the arm portion 190a near both ends in the longitudinal direction and is bent and fixed so as to be held from below by a holding claw 120c. The other end provided with the external thread of the capture rod 110 while capturing so as to surround the base 41 of the AC cord at a portion formed in a substantially U shape by the side portions 190d and 190d adjacent to the central portion 190c of the metal fitting 190. The tip is passed through the round hole of the hole-attached knob receiving bracket, and the cylindrical knob is screwed.

  Subsequently, the AC cord to which the AC plug 40 is connected is removed from the inlet 20 without applying any processing to the decorative plate 13 by rotating the two cylindrical knobs to uniformly press the pressing fitting 190 toward the AC plug 40. Can be prevented. When the shape and dimensions of the AC plug are different, the cylindrical knob can be turned to change the position of the pressing bracket over a wide range, so that it can be shared with almost all AC plugs on the market. This is much more convenient than a drop-out prevention tool that has been re-made and adjusted in size.

  By attaching the perforated knob receiving metal fitting, the pressing metal fitting used in the tie wrap and the fastener of the fifth and sixth embodiments can be shared, and the manufacturing cost can be reduced.

  Further, the mounting tool 30 is provided with trapezoidal overhanging portions 31c and 33c in the opposite direction of the sandwiched portion at the center of each of the plate-like rectangular surfaces 31 and 33, and both sides thereof are perpendicular to the inside from the rectangular surface. When the bending portion is provided as the reinforcing portions 31d, 31d, 33d, and 33d and the mounting tool is made of a thin metal plate, the tensile force received from the fixing tool is sandwiched between the entire pieces 35a1 and 35b1, and the rectangular surface 31, By strengthening 33 to prevent distortion, the AC cord was more reliably dropped.

  Here, the bent bar-shaped locking bar 110 and the pressing metal 190 are preferably made of a stainless steel or steel wire having a strength that does not easily deform, and the bent bar-shaped locking bar is 1.6 φ or more. Is preferably 2φ or more. A substantially U-shaped plug catching portion is formed by the side portion 190d bent at a right angle adjacent to the center portion 190c of the pressing metal, and the extension portion is once bent at right angles to both outer sides of the U shape. Protruding portions 190e and 190e are formed, and further vertically connected to the vertical capturing portions 190f and 190f at an angle of 80 to 85 degrees with respect to the capturing portion which is further horizontal, and further bent at a right angle to be substantially parallel to the side portion 190d. Arm portions 190a and 190a are formed in parallel, and a bent portion is formed by bending the tip thereof upward at a right angle.

  The plug capturing part reliably captures the plug 40 with such a size that the base part 41 of the plug of the AC cord can be deeply surrounded from three directions. Further, the side part 190d and the arm part 190a reciprocate beyond the center of the plug 40, and the arm part 190a of the pressing metal 190 acts as a lever with the connecting part of the side part 190d and the projecting part 190e as a fulcrum. At the same time, due to the structure of the side portion 190d and the vertical connecting portion 190f that make the mutual angle acute, when the arm portion 190a is pressed in the direction of the inlet 40 with a strong force, the entire catching portion is more reliably pressed against the shoulder portion 42 of the plug. . At the same time, the leg portion 190f and the bent portion 190b are formed in parallel, so that the hole-attached knob bracket can be conveniently fitted.

  Next, with reference to FIG. 12 (A) to FIG. 12 (D), an AC cord dropout prevention device according to an eighth embodiment of the present invention will be described.

  FIG. 12A is a perspective view showing a usage form of the AC cord drop-off prevention device of the present invention, which is composed of the mounting device 30 divided into the mounting elements 30a and 30b and the fixing device 100 to which the AC cord plug 40 is fixed. FIG. 12B is a front view of a bearing auxiliary tool 371 which is an improved E-ring of the present embodiment, and a cross-sectional view taken along line AA ′. FIG. 12C is a cross-sectional view in which the improved E-ring of this embodiment is mounted by inserting the bent portion 110b of the locking rod 110 into the mounting tool having the round locking hole of FIG. FIG. 12D shows the modified E-ring of this embodiment in which the locking hole is mounted on a square mounting tool and the bent portion 110b of the wire locking rod 110 is inserted as shown in FIG. 8 of the fourth embodiment. FIG.

  The wearing tool 30 of the eighth embodiment is the same as the wearing tool of the third embodiment. Further, the pressing tool 200 which is an element constituting the fixing tool 100 is obtained by adding a hole knob receiving bracket 120 to the pressing bracket 190 of the fourth embodiment to share the pressing bracket with the seventh embodiment. This is the same as described in. In these drawings, the same components as those shown in FIGS. 1 to 5 are denoted by the same reference numerals.

  In order to fix the AC cord plug 40 to the inlet 20 and prevent the AC cord from falling off, the AC plug 40 is first removed from the inlet, the screw 14 is removed at one end, and the decorative plate 13 is removed from the main body. Subsequently, the open ends of the two mounting elements 30a and 30b are opposed to each other so as to surround the peripheral portion 20c of the inlet 20, and the serrated engagement portions 35a21 and 35b31 and 35a31 and 35b21 of the both mounting elements are sandwiched, respectively. 35a1, 35a2, 35a3, 35b1, 35b2, and 35b3 are engaged so that the mounting elements 30a and 30b are pressed against the decorative board 13 and fixed to the inlet mounted on the device 12 so as to maintain mutual connection. Temporarily attached to the peripheral portion 20c in close contact with or substantially in close contact. Next, the decorative plate 13 is covered with the inlet 20 on which the mounting tool 30 is temporarily mounted so that the opening 15 of the decorative plate 13 penetrates the plate-like rectangular surfaces 31, 32 a, 32 b, 33, 34 b, 34 a of the mounting tool 30. Then, the screw 14 is tightened and the mounting tool 30 is fully mounted, and then the AC plug 40 is inserted back into the inlet 20.

  Subsequently, the bent portions 110b at one ends of the two bent rod-like locking rods 110 which are constituent elements of the fixing device 100 are inserted into the fixing device locking round holes 31a and 33a of the mounting device 30, respectively, and the E-rings are inserted. The bearing auxiliary tool 371 having a function is mounted by being engaged with the E-ring groove of the bending portion 110b of the bending locking bar across the position of the locking hole of the mounting tool, and the locking bar 110 falls off the mounting tool 30. To prevent.

  Since the bearing auxiliary tool 371 has an effect of increasing the thickness of the locking hole portion of the mounting tool 30 made of a thin metal plate, the bent portion 110b of the bending bar-shaped locking bar 110 can be reliably locked to the mounting tool 30 vertically. To.

  Moreover, it can mount | wear to the mounting tool with which a locking hole is not a round hole, and the locking | rock of the bending rod shaped locking bar which requires the locking hole of a round hole can be enabled. In this case, when the fixture 100 presses the AC plug in the inlet direction, a strong force generated in the direction of the holding bracket by the bent portion of the locking rod is received by the locking hole of the mounting tool 30 and is not applied to the bearing auxiliary tool. The tool can be made of a thin plate with a simple structure.

  Subsequently, a pressing member in which a knob receiving member 120 with a hole is attached in advance so that the knob receiving piece 120b provided with a round hole is placed on the arm portion 190a near both ends in the longitudinal direction and is bent and fixed so as to be held from below by a holding claw 120c. Other than providing the external thread of the capture rod 110 while capturing so as to surround the lead portion 41 of the AC cord at the portion formed in a substantially U shape by the side portions 190d and 190d adjacent to the central portion 190c of the metal fitting 190 The end of the end is passed through the round hole of the hole-attached knob receiving bracket, and the cylindrical knob is screwed. Subsequently, the AC cord to which the AC plug 40 is connected is removed from the inlet 20 without applying any processing to the decorative plate 13 by rotating the two cylindrical knobs to uniformly press the pressing fitting 190 toward the AC plug 40. Can be prevented. When the shape and dimensions of the AC plug are different, the position of the pressing bracket can be changed over a wide range by turning the cylindrical knob, so it can be used for almost any AC plug on the market. This is much more convenient than a drop-out prevention tool that has been re-made and adjusted in size.

  When the mounting elements 30a and 30b obtained by dividing the mounting tool 30 are mounted on the inlet 30, the plate-like rectangular surfaces 31a, 32b, and 34a are designed to have a space between them, and therefore the inlet 20 has different dimensions. However, the plate-like rectangular surfaces 31 and 33 can be brought into close or close contact with the inlet. Preferably, the mounting tool 30 is made of a thin metal plate of about 0.5 mm so that the mounting tool 30 is a decorative plate between the decorative plate 13 and the inlet 20. It can be mounted in a slight gap 13d due to the dimension allowance taken into account when designing the opening, and the sandwiched part that rises perpendicularly to the bottom of the plate-like rectangular surface is designed so that it cannot pass through the gap 13d. Therefore, it is possible to fix the mounting tool 30 to the inlet 20 without processing the decorative plate 13 or the device 12 at all, thereby preventing the AC cord from dropping off. It can be.

  Further, the mounting tool 30 is provided with trapezoidal overhanging portions 31c and 33c in the opposite direction of the sandwiched portion at the center of each of the plate-like rectangular surfaces 31 and 33, and both sides thereof are perpendicular to the inside from the rectangular surface. When the bending portion is provided as the reinforcing portions 31d, 31d, 33d, and 33d and the mounting tool is made of a thin metal plate, the tensile force received from the fixing tool is sandwiched between the entire pieces 35a1 and 35b1, and the rectangular surface 31, By strengthening 33 to prevent distortion, it was possible to prevent the AC cord from falling off more reliably.

  Here, the bent bar-shaped locking bar 110 and the pressing metal 190 are preferably made of a stainless steel or steel wire having a strength that does not easily deform, and the bent bar-shaped locking bar is 1.6 φ or more. Is preferably 2φ or more. A substantially U-shaped plug catching portion is formed by the side portion 190d bent at a right angle adjacent to the center portion 190c of the pressing metal, and the extension portion is once bent at right angles to both outer sides of the U shape. Protruding portions 190e and 190e are formed, and further to the above horizontal capturing portion, the vertical connecting portions 190f and 190f are directed downward at an angle of 80 to 85 degrees, and further bent at a right angle so as to be substantially parallel to the side portion 190d. Arm portions 190a and 190a are formed in parallel, and a bent portion is formed by bending the tip thereof upward at a right angle.

  The plug capturing part reliably captures the plug 40 with such a size that the base part 41 of the plug of the AC cord can be deeply surrounded from three directions. Further, the side part 190d and the arm part 190a reciprocate beyond the center of the plug 40, and the arm part 190a of the pressing metal 190 acts as a lever with the connecting part of the side part 190d and the projecting part 190e as a fulcrum. At the same time, when the arm portion 190a is pressed in the direction of the inlet 40 with a strong force due to the structure of the side portion 190d and the vertical connecting portion 190f that make the mutual angle acute, the entire capturing portion is more reliably pressed against the shoulder portion 42 of the plug. . At the same time, the leg portion 190f and the bent portion 190b are formed in parallel, so that the hole-attached knob bracket can be conveniently fitted.
