Description

  The present invention relates to a connector holding device, an audio device, an adapter device, and a pressing member, and in particular, effectively suppresses external factor vibration and noise caused by self-vibration from occurring in an outlet portion to which a power cable is connected. About what you can do.

  In general, when an electric device or the like is connected to a power source, an insertion plug at the tip of a power cable extended from the electric device or the like is connected to an outlet. In addition, when connecting multiple electrical devices to the power supply, if there are not enough outlets prepared in advance, multiple electrical outlets can be connected so that multiple plugs can be connected to each electrical device. An outlet box equipped with a power supply is used in consideration of its electric capacity.

  However, in the connection in which the plug blade member of the plug is held between the blade receiving member of the outlet, the connection state may be loose and vibration may occur. In order to avoid noise caused by such vibration from getting on the power supply and affecting the characteristics of electrical equipment, especially in the audio field where improvement of sound quality is important, fixing tools for plugs have been used. Proposed. For example, Patent Document 1 proposes to sandwich a plate-shaped fixture between an outlet and an insertion plug.

  On the other hand, since the 1990s, for the purpose of improving the sound quality, there has been an increase in audio equipment using a grounding 3P type outlet for connecting medical equipment in which the spring holding force of the blade receiving member is reinforced. In recent years, audio outlets that can further improve sound quality have been marketed and gained popularity.

  For example, there is an audio outlet in which the spring holding force is strengthened by making the blade receiving member thick or using a blade receiving member made of beryllium copper having excellent springiness and rigidity. In addition, precious metal plating such as gold, silver and rhodium is applied to the blade receiving member to reduce contact resistance, strengthen the strength of the mounting bracket to the wall, and excellent vibration damping characteristics to avoid sound quality deterioration Audio outlets that use useful synthetic resin for parts.

  By the way, in the connection between a power cable and an electric device (which may include an electronic device), an outlet connected to one end of the power cable is inserted into an inlet provided in the casing of the electric device, and the inlet There is also a form in which the insertion blade member on the side is held by the blade receiving member on the outlet side. With regard to such a connection form, conventionally, there has been proposed an apparatus that restricts the outlet from being inadvertently pulled out of the inlet. For example, Patent Document 2 and Patent Document 3 propose a device that restricts the outlet from being completely pulled out from the inlet by hooking a wire member having elasticity to a power cable on the outlet side.

Also, wall outlets (model number CON-5) and outlets with plug fittings that are fixed by screwing the cylindrical curved part from both sides with a metal fitting that surrounds the cylindrical curved part of the plug with two sheets. Boxes (model number C-66R) and the like are commercially available from CSE Co., Ltd. (http://www.cse.ne.jp/).

  In such connection between the plug and the outlet, since the insertion blade member of the plug is sandwiched between the blade receiving member of the outlet by a spring holding force, looseness is likely to occur. For this reason, for example, the positional relationship between the insertion blade member and the blade receiving member is deviated, so that the contact area decreases and the contact electrical resistance increases, or the insertion blade member and the blade receiving member are exposed to the space through the gap. The problem is that the sound wave from the speaker of the audio device directly vibrates the insertion blade member and the blade support member, or the contact surface of the insertion blade member and the blade reception member because the insertion plug causes a pendulum movement vertically and horizontally There arises a problem that vibration occurs in the case. Such vibrations generate a voltage (Fleming's law) and cause noise in audio equipment.

  In addition, since the housing of a general outlet or an insertion plug is molded from a thin synthetic resin, there is a problem that a large resonance vibration is generated by itself and causes deterioration of sound quality. Here, supplementary explanation will be given for resonance vibration. Examples of vibrations that are deeply related to the present invention include external factor vibrations, self-vibrations, and resonance vibrations. First, external factor vibration is vibration transmitted from an adjacent object such as a sound pressure from a speaker when using audio. Self-vibration is vibration generated from the inside. Furthermore, although repulsive force is generated by a magnetic field generated when a current flows in a reverse direction in a parallel cable or the like, it is a vibration generated when an alternating current corresponding to a music signal flows when an audio device is connected. The resonance vibration is a vibration that is greatly enhanced in the natural frequency of the object by the resonance effect using the external factor vibration or the self-vibration as a trigger.

  Resonance vibration can be attenuated by the consumption of vibration energy, so vibration energy can be converted into thermal energy and consumed, or other adjacent objects can be vibrated to consume their own vibration energy and attenuate the vibration. preferable. However, when the consumption of vibration energy is insufficient, the conductive member is vibrated and finally noise is generated. That is, it is preferable to apply a large pressure so that the plug and the outlet are brought into close contact with each other without gaps, and to convert the vibration energy of both resonance vibrations into heat energy by friction to be consumed. Furthermore, there is a need for countermeasures such as newly preparing a heavy object, closely contacting it with a large pressure, and oscillating the heavy object to consume its own vibration energy.

  However, even if the spring holding force of the audio outlet is strengthened, it is difficult to completely eliminate the looseness. In recent years, there is a product using a very thick cable having a diameter of about 20 mm as a power cable for audio, and the insertion plug may be inclined due to its weight. Further, merely applying the noble metal plating to the blade receiving member is only a small improvement regarding the problem of contact electrical resistance and the problem of vibration due to friction based on the pendulum motion. In short, even if you aim to improve sound quality, it is not enough to use an audio outlet as described above. Actually, it is difficult to avoid sound quality degradation.

  Therefore, as described in Patent Document 1, even when a plate-shaped fixture is sandwiched, the plug blade member of the plug is sandwiched by the blade receiving member of the outlet and is in contact connection. Therefore, the problem caused by the structure in which the blade receiving member clamps the insertion blade member with the spring holding force cannot be solved. Further, assuming that the devices described in Patent Documents 2 and 3 are used, the elastic wire member only touches a power cable or the like unless a load to be pulled out is applied. The problem caused by the structure using the spring holding force of the member cannot be solved.

  Further, when the above-mentioned CSE plug fixing bracket is used, since the screwing is performed not in the outlet direction but in the direction sandwiching the cylindrical curved surface of the insertion plug, there is no pressure on the connection between the outlet and the insertion plug. Is not sufficient as a countermeasure against resonance vibration. In addition, gaps are also generated unless the screws are screwed very carefully. Furthermore, since the fixing bracket itself causes a considerable amount of resonance vibration, this is eventually reflected in the sound. In this case, the sound may become a “dislike sound” in the sense of an individual due to compatibility with the audio equipment. This problem is often solved by changing the frequency of resonance vibration by exchanging the material of the fixture, etc., but it is difficult to solve when the material of the fixture is not easily replaceable. is there. Therefore, although it is effective for a part of the problems caused by the structure in which the blade receiving member clamps the insertion blade member with the spring holding force, it is still insufficient, and the effect particularly in the portion related to the resonance vibration is very small. .

  Therefore, an object of the present invention is to provide a connector holding device or the like that can supply high-quality power to an electronic device by effectively attenuating vibration caused by sound pressure or the like. Here, the audio equipment is not limited to pure audio, but may include equipment used for so-called AV equipment including video and others. Such audio equipment may include power supply wiring equipment.

  A configuration of an invention that solves the above problem relates to a connector holding device, wherein a connector body portion that is disposed at one end portion of a power cable and incorporates a connection terminal that conducts to a conductive wire in the power cable is connected to the power cable. It has a pressing means for pressing from the connection direction of the connection terminal in a direction in which the connection terminal of the connection terminal is made to approach a counterpart member provided with a connected terminal.

  As described above, according to the present invention, the connector body portion connected to the one end portion of the power cable is approached from the connection direction to the counterpart member including the connected terminal to which the built-in connection terminal is connected. The connector body portion can be held in a state where it is pressed and pressed in the direction to be pressed, and the connector body portion is integrally connected to the mating member. For this reason, while maintaining the state in which the blade receiving member and the insertion blade member are in pressure contact with each other and electrically connected to each other, the connection state of the blade receiving member and the insertion blade member by the connection between the connector body portion and the mating member Can be held. At the same time, the resonance vibration of the connector body part and the mating member can be attenuated by the consumption of vibration energy due to friction. Generation | occurrence | production can be suppressed. From this, for example, even when used in an environment where the sound pressure is large, it is possible to suppress the vibration caused by the sound pressure from affecting the contact connection between the blade receiving member and the insertion blade member. Therefore, even if the sound pressure that causes the vibration is received, it is hardly affected, and a high-quality power source free from vibration noise can be supplied to an electronic device such as an audio device. As a result, the electronic device can be operated with high performance, and for example, high-quality music without noise can be enjoyed by the audio device.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the following description is made for explaining the embodiments of the present invention, and the present invention is limited to these embodiments. It is not a thing. The same or the same type of elements are denoted by the same or related symbols, and redundant description is omitted.

  1 to 4 are views showing a first embodiment of a connector holding device according to the present invention. In FIG. 1, a connector holding device 10 is a plate-like plate that is connected to one end of a power cable 100 and is set on the back side of an insertion plug (connector body portion) 110 that is connected to an outlet (mating member) 120. A member (pressing member) 21 and a mounting screw (screw member) 30 for fixing the plate member 21 to the outlet 120 by screws are configured. A commercially available general-purpose product is sufficient as the mounting screw 30 used here.

  Here, the insertion plug 110 has three (hot, cold, ground) insertion blade members (connection terminals) protruding vertically from the front side of the main body member 114.

  On the other hand, the outlet 120 is formed with three (hot, cold, ground) insertion holes in the corresponding relative positions for opening the three insertion blade members of the insertion plug 110 so that they can be inserted. Inside the insertion hole, a blade receiving member (connected terminal) (not shown) that is in electrical contact with the three insertion blade members to be inserted is sandwiched. The outlet 120 has a decorative plate 124 attached to the front side, and the connection block 125 in which a set of insertion holes is arranged is located in an exposed hole 124 a that opens in the decorative plate 124. The insertion blade member of the plug 110 is exposed so that it can be inserted. In this embodiment, two sets of grounded 3P type connection blocks 125 are provided, but may be one set or three or more sets. Further, the specification may be a groundless 2P type.

  As shown in FIG. 2, screw holes 131 and 132 into which the mounting screws 30 are screwed are formed in the decoration plate 124 of the outlet 120 at symmetrical positions around the connection block 125. The mounting screw 30 is produced so that the threaded portion 31 is longer than the height of the main body member 114 of the insertion plug 110 (the length in the direction in which the insertion blade member extends) plus the thickness of the plate member 21. Has been.

  The plate member 21 is formed in a plate shape as shown in FIG. 3, and has a substantially rectangular area and shape that can cover and cover the installation area of the connection block 125 and the screw holes 131 and 132 of the outlet 120. Have. And the short side of a rectangle is cut off in parallel so that the area | region corresponding to the screw holes 131 and 132 may be left, and the protrusion part (engagement part) 23 and 24 is left on both ends. Further, the plate member 21 is formed with a slit (cable cutout portion) 25 that is cut out from the center of one long side of the rectangle toward the center, and the protruding pieces 23 and 24 also have long sides. Slits (screw notches) 27 and 28 that are cut out from the side center toward the center are formed. The slit 25 allows the power cable 100 to be inserted from the opening side so as to be positioned at the center, and the main body portion of the plate member 21 on the rear end surface (back surface) of the plug 110 connected to the power cable 100. It is formed by cutting out a shape to face each other. In addition, the slits 27 and 28 can be positioned in the center by inserting the threaded portion 31 of the mounting screw 30 from the opening side, and are formed by being cut out in a shape that makes contact with the head portion 32 of the mounting screw 30. Has been. The head portion 32 is formed in a so-called knurled shape in which the groove shape is continuous so that the outer peripheral surface can be picked and rotated. In addition, in order to press the plug 110 to the outlet 120 with a large pressure and suppress each resonance vibration, it is preferable that the plate member 21 has a structure with high rigidity. For example, it is preferable to use a stainless plate having a thickness of 1 mm or more, a duralumin having a thickness of 2 mm or more, or the like. The same applies to the second embodiment described later.

  Accordingly, the plate member 21 can insert the power cable 100 adjacent to the plug 110 connected to the outlet 120 into the slit 25. Similarly, the threaded portion 31 of the mounting screw 30 that is screwed into the screw holes 131 and 132 of the outlet 120 in advance can be inserted into the slits 27 and 28. Therefore, the plate member 21 can easily put the main body portion (pressing portion) against the rear end surface of the insertion plug 110, and the projecting portions 23 and 24 are connected to the head portion 32 of the mounting screw 30. Can be face to face. As shown in FIG. 4, the plate member 21 can be easily attached in a state in which the mounting screw 30 is rotated to press-contact the head portion 32. Can be kept pressed against the outlet 120 side.

  Thus, in this embodiment, since the plug member 110 connected to the outlet 120 is held in a state where the plate member 21 is pressed and pressed, the connection plug 110 is integrated with the outlet 120. can do. For this reason, even if it receives the factor of vibration, maintaining the state which press-contacts the insertion blade member in the receptacle 120 in the outlet 120 without gap, and is electrically connected, even if it receives the factor of a vibration, it is the insertion plug 110 (insertion blade member). ) And the outlet 120 (blade receiving member), it is possible to suppress an increase in vibration that is relatively displaced. At the same time, the resonance vibration of the plug 110 and the resonance vibration of the outlet 120 can be attenuated by the consumption of vibration energy due to friction. Therefore, for example, even when used in an environment where a high output audio device is installed, the vibration of the plug 110 due to the sound pressure of the high output can be suppressed, and so-called noise is not generated. It is possible to supply high-quality power that does not ride on electronic equipment such as audio equipment. As a result, it is possible to enjoy high-quality music without noise.

  Next, FIGS. 5-8 is a figure which shows 2nd Embodiment of the connector holding | maintenance apparatus based on this invention. In FIG. 5, the connector holding device 20 fixes the plate member 21 with a mounting screw 30 via a pair of vertical pole members (auxiliary members) 11, 12 standing on the surface side of the outlet 120. It is like that. What is necessary is just to select the thing of required length for the thread part 31 of the attachment screw 30. FIG.

  The pole members 11 and 12 are made shorter than the height of the main body member 114 of the insertion plug 110 (the length in the direction in which the insertion blade member extends). FIG. 6 and FIG. ), Screws 11b and 12b are provided on the base end face side, and are fixed by being screwed and fixed to the screw holes 131 and 132 of the decorative plate 124. Screw holes 11a and 12a are formed so as to be screwed together. That is, the pole members 11 and 12 have the screw holes 11a and 12a positioned at symmetrical positions around the connection block 125 of the outlet 120, as in the first embodiment. The pole members 11 and 12 are not limited to the form in which the screws 11b and 12b are provided and screwed to the decorative plate 124, but screw holes are formed on the base end surface side to form screws from the back side of the decorative plate 124. The form to stop may be sufficient. Alternatively, the decorative plate 124 may be made of a resin material and may be firmly bonded by melting and bonding. A rib member may be used instead of the pole members 11 and 12. For example, in the connector holding device 60 shown in FIG. 7, the insertion plug 110 and the outlet 120 are connected by screwing the attachment screw 30 into the screw holes 61 a and 62 a formed in the rib members 61 and 62.

  Thereby, the plate member 21 can be made into the state which makes a main-body part face the rear-end surface of the insertion plug 110 similarly to the above-mentioned embodiment, Moreover, the projecting piece parts 23 and 24 are made into the pole members 11 and 12. It can be made to face the front end surface. Then, as shown in FIG. 8A, the plate member 21 can be easily mounted in a state where the mounting screw 30 is rotated and fastened to the tip surfaces of the pole members 11 and 12, and the pole members 11 and 12 are attached to each other. Since it is shorter than the main body member 114 of the insertion plug 110, the rear end surface of the insertion plug 110 can be pressed and the front end surface can be pressed against the outlet 120 side.

  Next, a method for dealing with the plug 110 having a different length will be described. Although a method of responding by simply preparing a plurality of mounting screws 30 and pole members 11 and 12 having different lengths may be used, a method of responding with deeper screw holes will be described here. As shown in FIG. 8 (a), the connector holding device 20 has a structure in which the main body member 114 is connected to the insertion plug 110 of a short type as shown in FIG. 8 (b). Even when a long insertion plug 110 is connected, the plate member 21 is fastened to the rear end surface of the main body member 114 by screwing the mounting screws 30 into the pole members 11 and 12, and the connection state of the insertion plug 110 is maintained. can do.

  In the first embodiment described above, the thread 31 of the mounting screw 30 passes through the screw holes 131 and 132 even when plugs having different lengths are used as in the present embodiment. It is possible to cope with.

  Thus, in this embodiment, in addition to being able to obtain the same operational effects as in the first embodiment described above, the weight increase of the pole members 11 and 12 acts positively on the suppression of resonance vibration. Vibration can be damped more effectively. Moreover, since the exposure of the thread part 31 of the attachment screw 30 decreases, the beauty can be maintained.

  Next, a third embodiment of the connector holding device according to the present invention will be described. Although not shown in the figure, in the third embodiment, in order to further suppress the resonance vibration of the outlet 120 and the plug 110, a method of consuming the vibration energy of itself by vibrating adjacent heavy objects is adopted. To do. The plate member 21 is made of a material that easily transmits vibrations, and is made heavy by increasing the plate thickness. For example, a stainless plate having a thickness of 5 to 20 mm may be used, and other materials such as tungsten, various copper alloys, titanium, duralumin, iron, and fine ceramics may be used. The same materials are preferable for the pole members 11 and 12, the rib member, the decorative plate 124, the mounting screw 30, the adapter shown in FIG. 13 to be described later, and the adapter in FIG. 17 to be described later.

  The plate member 21 itself causes some resonance vibration due to vibration from the plug 110. This causes a reverse flow and causes the outlet 120 and the plug 110 to vibrate in reverse, which also affects the sound quality. In order to suppress this, materials with high internal loss of vibration energy (materials that stop immediately even when squealing) can be used, but metal plating, multiple metal bonding materials, vibration-absorbing synthetic resin can be used. The resonance vibration of the plate itself can also be suppressed by the method of pasting.

  Further, by using this plate resonance vibration and preparing various plate members 21 and replacing them, the sound quality can be changed slightly differently. Furthermore, since the plate member 21 can be replaced even in an energized state, the audio system can be easily tuned by replacing the plate member 21 while listening to the sound to bring it closer to the desired sound.

  Thus, in the present embodiment, in addition to obtaining the same operational effects as the above-described embodiment, vibration can be more effectively suppressed by increasing the weight of the plate member 21. Further, by preparing a plurality of replacement plate members 21 using different materials, a subtle change in sound quality can be enjoyed.

  Next, FIG. 9 is a diagram showing a fourth embodiment of the connector holding device according to the present invention. The damping characteristics are further improved by combining the resonance vibration characteristics unique to each material by overlapping plate members made of different materials. That is, plate members 21a, 21b, and 21c made of different metals are prepared. Since the plate member 21b sandwiched between the one plate member 21a and the plate member 21c does not require strength, the plate member 21b is not limited to metal and may be made of a resin material having a vibration damping function.

  As described above, in the present embodiment, in addition to the operational effects of the above-described embodiment, the plate member 21 is composed of a plurality of different materials, so that the resonance vibration of the plate member 21 is reduced and more effectively. Vibration can be damped. Moreover, since all sounds change depending on the combination in tuning, the choices are greatly increased compared with the case of replacement with a single sheet.

  In the present embodiment, the case where the pole members 11 and 12 are used will be described as an example. However, the same operation can be achieved even when the mounting screw 30 is directly screwed to the outlet 120 as in the first embodiment. Needless to say, an effect can be obtained (the same applies to other embodiments described below).

  Next, FIG. 10 is a diagram showing a fifth embodiment of the connector holding device according to the present invention. As shown in FIG. 10, the pole members 11 and 12 are installed not on the decorative plate 124 but on the main body 120 a of the outlet 120. The present embodiment can be applied when the decoration plate 124 is not provided, or when the decoration plate 124 is used, a through hole that allows the pole members 11 and 12 to penetrate the decoration plate 124 is formed. Good.

  Thus, in this embodiment, since it has the same structure as the above-mentioned embodiment, the same effect can be obtained.

  Next, FIG. 11 is a diagram showing a sixth embodiment of the connector holding device according to the present invention. As shown in FIG. 11, pole members 11 and 12 are installed in an outlet box 200 in which a plurality of sets (one port) of connection blocks 125 are arranged in place of a two-port outlet 120 installed on a wall or the like. ing.

  The pole members 11 and 12 are also installed on both sides of a later-described IEC inlet 210 installed in the outlet box 200 so as to have the same positional relationship as the connection block 125 of the outlet 120 described above. Here, the IEC inlet 210 has three (hot, cold, ground) insertion blade members in the shape of the recess as well as the three (hot, cold, ground) insertion blade members of the insertion plug 110 described above. (See FIG. 15), the other end portion (connector body portion) 109 of the power cable 100 containing a blade receiving member as a connection terminal can be inserted and removed.

  Thus, in this embodiment, the plug 110 connected to the outlet box 200 can be pressed and pressed by the plate member 21 in the same manner as in the above-described embodiment, and similarly, The other end 109 of the power cable 100 connected to the IEC inlet 210 can also be held by being pressed by the plate member 21. Therefore, it can restrict | limit that the other end part 109 of the plug 110 or the power cable 100 vibrates.

  Here, in the present embodiment, the outlet box 200 in which only a plurality of connection blocks 125 are provided has been described as an example. However, the present invention is not limited to this. For example, as illustrated in FIG. The present invention can be similarly applied to the (electrical device) 300, and although it is omitted from the drawing, it is needless to say that the present invention can also be applied to a transformer device, an acoustic device, and the like. Further, the IEC inlet 210 has been described as an example. However, the present invention is not limited to this example. For example, another standard inlet such as a glasses-type inlet can be similarly applied.

  Next, FIGS. 13 to 16 are views showing a seventh embodiment of the connector holding device according to the present invention. In FIG. 13, the connector holding device 70 is ribs installed on both sides of the IEC inlet 210 included in the electronic apparatus 400 such as an audio amplifier and a CD player shown in FIG. 14 together with the pole members 11 and 12 (not shown) and the plate member 21. Members 65 and 66 are provided. Here, the IEC inlet 210 has a structure conforming to the standard of the International Electrotechnical Commission, and as shown in FIG. 15, three of the plugs 110 described above (hot, cold, ground) ), Three (hot, cold, ground) insertion blade members are housed. Thereby, the other end part (connector body part) 109 of the power cable 100 incorporating the blade receiving member is detachably connected to the IEC inlet 210.

  The rib members 65 and 66 are disposed on both ends of the installation plate 71 that is formed to be horizontally longer than the installation area of the IEC inlet 210, and are fixed in parallel with the short side of the installation plate 71. Further, a slit 72 is formed in the installation plate 71 at a position corresponding to the screw 230 for attaching the IEC inlet 210 to the electronic device 400, and the slit 72 extends from the long side end of the installation plate 71. It is formed by cutting inward in parallel with the short side. The rib members 65 and 66 are screw holes 65a and 66a into which the screws 11b and 12b of the pole members 11 and 12 are screwed so that the plate member 21 can be fastened and fixed by attaching the pole members 11 and 12. Are perforated.

  Accordingly, as shown in FIG. 16, the rib members 65 and 66 can be installed on both sides by inserting the installation plate 71 downward by simply loosening the screw 230 of the IEC inlet 210. The screw 30 can be easily attached.

  Thus, in the present embodiment, in addition to the operational effects of the above-described embodiment, the rib members 65 and 66 for mounting and fixing the pole members 11 and 12 can be installed on both sides of the IEC inlet 210. The plate member 21 can be fixed to the pole members 11 and 12. Accordingly, even at the other end 109 of the power cable 100 connected to the IEC inlet 210, vibration can be suppressed and noise generation can be easily limited.

  Here, in this embodiment, the case where the pole members 11 and 12 are installed and the plate member 21 is attached has been described as an example. However, the present invention is not limited to this. For example, the pole members 11 and 12 are not installed. Instead, the thickness of the rib members 65 and 66 may be increased in the direction of the other end 109 so that the plate member 21 can be directly attached and fixed to the rib members 65 and 66. In addition, the IEC inlet 210 has been described as an example. However, the present invention is not limited to this. For example, another standard inlet such as a glasses-type inlet can be similarly applied.

  FIG. 17 is a view showing an eighth embodiment of the connector holding device according to the present invention. In FIG. 17, the connector holding device 80 includes a fixture (adapter device) 81 in addition to the plate member 21 (not shown). The fixture 81 is connected to the upper facing plate 82 facing the upper surface of the electronic device 400, the lower facing plate 83 facing the lower surface of the electronic device 400, and both sides of one side of the facing plates 82 and 83. And the fixing screws 89 screwed into the screw holes 82a penetrating the upper facing plate 82. In addition, screw holes 85a and 86a are formed in the prism members 85 and 86 at the same positions as the screw holes 65a and 66a of the rib members 65 and 66 in the above-described embodiment.

  As a result, the fixture 81 causes the lower facing plate 83 to be brought into contact with the upper surface of the electronic device 400 by abutting the tip of the threaded portion 89a of the fixing screw 89 that is screwed into the screw hole 82a of the upper facing plate 82 and protrudes. The prismatic members 85 and 86 can be attached to the lower surface of the electronic device 400 so as to be parallel to the installation surface of the IEC inlet 210 and positioned on both sides. In other words, the prismatic members 85 and 86 have a horizontal bar shape with respect to the installation surface of the IEC inlet 210.
