Is configured.

In the present invention, an electrical connector is used only for connecting and distributing a power cable, a connector used only for connecting and distributing a communication cable such as a LAN cable or a telephone line, or a power cable and a communication cable. Includes those used for both connection and distribution with. When used only for power supply, it becomes an outlet. Even when it is used for both power supply and communication connection, it can be said to be an outlet with a communication cable connection function when the power supply is the main one. Hubs and routers may also be included when used for connection of communication lines only.

The present invention includes various configurations, examples of which are specified in claims 2 and below. Of these, in the invention of claim 2, in claim 1,
"The shelves are supported by the right and left outer plates, a height position between the one of the right and left outer plates, and the shelf plate and desk surface at least one of the inner surface, the electrical The connector is fixed. ''
Is configured.

The invention of claim 3 is the same as that of claim 1 or 2,

An electrical connector for power supply or communication or both is fixed to one wide surface,
The electrical connector has a front surface and a rear surface that are vertically elongated and a top surface and a bottom surface that is longitudinally longitudinal, and has a thickness in the left-right direction that is much smaller than the front-rear dimension and the vertical dimension. On the front surface and the rear surface of the dynamic connector, connection ports that allow plugging and unplugging of plugs for electrical connection are arranged in the vertical direction.
Further, the shelf plate is supported by the left and right outer plates, and at the height position between the shelf plate and the desk top surface on the inner surface of at least one of the left and right outer plates, The electrical connector is fixed.''
In the basic configuration
``A female screw hole into which a laterally long horizontal screw penetrating the outer plate or the partition plate can be screwed is vertically separated at approximately the front-rear intermediate portion of one of the left and right wide surfaces of the electrical connector. Two of them are formed, and a positioning pin is screwed into one of the two female screw holes, while a pair of upper and lower through holes having the same spacing as the upper and lower female screw holes of the electrical connector are formed in the left and right outer plates. Is open, and one electrical connector is turned upside down and leftward and rightward without changing the front-back posture, and is attached to the left and right outer plates, and is fixed with one screw while holding the posture with the positioning pin. Is allowed. ''
Is configured.

In the present invention, since the electrical connector such as the outlet is fixed to the inner surface of the outer plate or the partition plate that constitutes the shelf device, an article such as a notebook can be stored deeply until it hits the back plate. Moreover, since the electrical connector has an elongated shape on both the front and rear surfaces and the upper and lower surfaces, and has a thin structure as a whole, the lateral dimension of the electrical connector in the shelf device is considerably reduced. As a result, the space for accommodating articles such as notebooks can be set as wide as possible in the left-right direction, and the storability of the articles is excellent.

Further, since the electrical connector can be arranged close to the front end side of the outer plate or the partition plate, the connection port formed on the front surface can be easily visually recognized and the plug can be easily inserted and removed. Further, since the electrical connector is provided on the side surface of the outer plate or the partition plate, for example, when the electrical connector is arranged below the shelf board, articles such as texts and notebooks are placed below the shelf board. In storing in space, even if the height of the article is high, the upper end of the article cannot be caught by the electrical connector. From this aspect as well, the product can be stored easily.

Now, electric and electronic devices used in a desk having a shelving device are often placed on the desk except for a lamp. Therefore, from the viewpoint of beautiful treatment of cables, it can be said that it is reasonable to arrange the electrical connector such as an outlet at a position close to the desk (lower part). In this respect, according to the second aspect, since the electrical connector is arranged between the shelf plate and the desk top surface, it is possible to prevent the cable from hanging down vertically for a clean wiring.

Generally, the connection port of a household power outlet has two sets of electrode holes, and correspondingly, the plug has two sets of electrodes. The size of the plug for the power source is large in the direction in which the electrodes are arranged, and the width crossing the direction in which the electrodes are arranged is generally narrow. Therefore, by adopting a configuration in which the connection ports are vertically arranged as in the present invention, the horizontal width of the connection ports can be made as small as possible, which can contribute to an increase in the amount of articles stored in the shelving device.

Moreover, if a pair of electrode holes are arranged vertically, the plugs can be inserted and removed by grasping from both left and right sides with fingers, but since the connection port is displaced to the side opposite to the outer plate or partition plate, It is possible to prevent the plug from hitting the outer plate or the partition plate, which makes it easier to insert and remove the plug.

Furthermore, even if the plug has a large contact area with the outlet, such as a plug with a built-in transformer, a plug with a grounding part, or an adapter for a deformed plug, the connection port is the outer plate or the partition plate. By being shifted to the opposite side (inner side of the shelf device), the plug can be inserted and removed without interfering with the outer plate and the partition plate. That is, a large plug can be used without increasing the left-right width dimension of the outlet.

A lighting device is usually installed in a shelf device for a learning desk, and when a switch of the lighting device is provided in an outlet as in Patent Document 2, the power of the lighting device can be turned on/off without extending the hand greatly. .. Therefore, it becomes easy to turn on/off the lamp. Also in the present invention, if the structure of claim 4 is adopted, the lamp can be turned on and off by extending the hand a little, so that the lamp is easy to use.

Further, according to claim 4, since the upper and lower connection ports sandwiching the switch are widely spaced, a normal power plug such as the above-mentioned transformer built-in plug or an adapter for connecting the round bar electrode plug is used. Even larger plugs can be connected without blocking other connection ports.

Also, for example, there are devices (stationary devices) that are often left on the desk, such as pencil sharpeners and desktop PCs. If these plugs are inserted into the front of the outlet, Device may become unusable or the stationary device may be unplugged by mistake. Of these, it can be said that the fact that other devices cannot be used can be dealt with by increasing the number of connection ports on the front surface of the outlet, but this causes a problem that the outlet becomes large.

On the other hand, if the configuration of claim 4 of the present application is adopted, the number of connection ports can be increased by effectively utilizing the space on the rear surface of the outlet, and the power plug of the stationary device can be connected to the rear surface of the outlet, It is possible to increase the number of devices that can be used (the number of connection ports) while preventing an increase in size, and prevent erroneous operation in which the power plug of a stationary device is accidentally pulled out.

The outlet can have a built-in breaker function that shuts off the power supply when an overcurrent flows, but the breaker must be reset by a button. When the connection port for the lamp and the connection port for the stationary device are provided on the upper and lower sides of the reset button as in claim 5, the interval between the connection port for the lamp and the connection port for the stationary device can be widened. Therefore, it is possible to connect even a large-sized plug without any trouble, and it is possible to eliminate the problem of touching another plug when inserting or removing one plug.

Electrical connectors such as outlets can be fixed to the right side plate fixed to the left outside plate, and can be used left or right depending on the user's preference and the relationship with equipment installed on the desk. It is user-friendly to keep it. In this case, if the right-use product and the left-use product are manufactured separately, the number of types of electrical connectors is increased accordingly, so that there is a problem that the cost increases and the management of the product increases. Further, it is necessary to hold the electrical connector in a state in which it does not rotate when the plug is inserted and removed, and it can be said that it may be fixed with two screws for that purpose, but this causes a problem that it takes time to screw it in. ..

On the other hand, if the configuration of claim 6 is adopted, one type can be used for left-handed use and right-handed use, thus preventing an increase in cost. Also, even if it is fixed using a single screw, the positioning of the electrical connector is held by the positioning pin so that the electrical connector is easy to install, but the plug can be inserted and removed stably. It can be carried out. The electrical connector can be used for right-hand use and left-hand use by turning it upside down, left-right, but if you want the screw height to be the same for both left-hand use and right-hand use, screw it into the electrical connector. You can change the vertical position of the pin.

In the present application, left and right and front and rear words are used to specify the direction, but these words are based on the orientation of a person who uses the desk in a normal posture. The front-back direction is the same as the depth direction, and the left-right direction is the same as the frontage direction.

This embodiment is applied to the wooden shelf device of the learning desk 1. The learning desk 1 has a top plate 2 that is a quadrangle in plan view (a horizontally long rectangular shape) and left and right legs 3 that support the top plate 2. Below the right side of the top plate 2, a plurality of upper and lower stages are provided. A sleeve cabinet portion (not shown) having a drawer is provided. A sleeve cabinet separate from the study desk may be provided, and in this case, the sleeve cabinet can be arranged at any of left and right portions of the space below the top plate 2.

A shelf device 4 is arranged at the rear of the top plate 2. The shelving device 4 includes left and right outer plates 5 and 6 forming left and right ends thereof, a shelf plate 7 horizontally arranged between the left and right outer plates 5 and 6, and rear ends of the left and right outer plates 5 and 6. And a back plate 8 disposed between the parts. The outer plates 5 and 6 are vertically long rectangles and stand upright on the desk top surface, and are fixed to the top plate 2 by clamp fittings ( not shown). The shelf plate 7 is divided into right and left parts by a vertical partition plate 9 at the right side portion.

Then, between the middle partition plate 9 and the right side outer plate 6 and below the shelf plate 7, two upper and lower drawers 10 are arranged. The drawer 10 is supported by rails provided on the middle partition plate 9 and the right outer plate 6 so as to be movable back and forth. Therefore, the lower end of the middle partition plate 9 does not reach the desk top surface, and there is a large gap between the middle partition plate 9 and the desk top surface. As shown in FIG. 3, the front end portion of the shelf board 7 is made of a wooden decorative edge member 7a.

The back plate 7 is upright with its lower end surface in contact with the top plate 2, and is fixed to the inner side surfaces of the left and right outer plates 5 and 6 with dowels or the like. As clearly shown in FIG. 3, the rear surface of the back plate 8 is slightly displaced from the rear end surfaces of the outer plates 5 and 6. Therefore, for example, when the outer plate 5 is applied to the wall of the building, a space is formed between the wall and the back plate 8 with a slight front-rear spacing. As shown in FIG. 2, wiring notches 11 for inserting cables are formed at the lower left and right corners of the back plate 8.

For example, as shown in FIG. 1, the left and right outer plates 5 and 6 are connected at their upper rear ends by a round bar-shaped reinforcing bar 12. The reinforcing bar 12 penetrates the upper rear end of the partition plate 9. The middle partition plate 9 meshes with the back plate 8 in the front and back, and both are fixed by dowels or the like.

A plurality of movable partition plates 13 are arranged in the shelf plate 7 between the left outer plate 5 and the middle partition plate 9 so as to be movable left and right. At the rear end and the lower end of the movable partition plate 13, a stabilizing member 14 whose side shape is shown in FIG. 3 is fixed, and the L-shaped left and right projecting portions 14 a provided on the stabilizing member 14 serve as a shelf board. He holds 7 from the back and from below. Therefore, a part of the shelf plate 7 between the left outer plate 5 and the partition plate 9 has a slight gap between it and the back plate 8.

A pair of left and right support plates 15 opposed to each other is fixed to the lower surface of the top plate 2 near the left outer plate 5, and two left and right support plates 15 support a two-stage plate 16 so as to be movable back and forth. .. The plate 16 is fitted in a groove formed in the support plate 15. On the plate 16, anything thin such as prints brought back from school by children, files of the child, notebooks, etc. can be placed and stored.

A lamp 18 is attached to the left outer plate 5. The lamp 18 includes a column 19, a forward arm 20 attached to the upper end of the column 19, and a shade 21 with a downward opening attached to the front end of the arm 20. Inside the shade 21, a straight tubular LED lamp or a fluorescent lamp is provided. Are arranged. A base body 22 having a downwardly facing foot portion 22a is attached to the lower end of the column 19, and the foot portion 22a is horizontally pivotable on a tubular portion 23a of a receiving metal fitting 23 fixed to the outer surface of the left outer plate 5. It is fitted.

The support column 19 is connected to the base body 22 so as to rotate back and forth around a horizontal axis, so that the support column 19 can be tilted back and forth. Further, the arm 20 is also connected to the upper end of the column 19 via a john int so that it can be rotated about a horizontal axis (so that it can be swung). Further, the shade 21 is connected to the front end of the arm 20 so that the shade 21 can be horizontally rotated.

(2). Outlet Structure As shown in FIGS. 2 and 3, a power distribution outlet 24, which is an example of an electrical connector, is attached to the inner side surface of the left outer plate 5 at the front side and near the lower end. Next, the outlet 24 will be described with reference to the drawings starting from FIG.

Outlet 24, the left and right sides are slightly vertically elongated rectangular in side view, forms a plate-like appearance as a whole. That is, the front surface 25, the rear surface 30, and the upper and lower surfaces form an outer circumference, and the outer peripheral surface and the left and right side surfaces are continuous, but the front surface 25 and the rear surface 30 are vertically long rectangles, and the upper and lower surfaces are long front and back. It has a rectangular shape, and the horizontal thickness is much smaller than the vertical height and front-back width.
As shown in FIGS. 4 and 5, a lamp switch 26 is provided on the front surface 25 at an upper and lower intermediate height position, and two upper and lower electrodes are provided on the front surface 25 at two upper and lower positions sandwiching the lamp switch 26. holes 27a, general coupling port 27 consisting 27b are formed side by side in a row.

Electric/electronic devices used on desks include portable devices such as game consoles, cell phone/smartphone chargers, notebook computers, and electronic learning machines, but these are always available at desk 1. a non equipment, where, call them for convenience generally equipment, are shown by reference numeral 28 a plug for supplying power to general equipment called common plug. The general-purpose connection port 27 is used to connect the general-purpose plug 28.

Although the switch 26 for a lamp of the embodiment is a circular push type and does not project from the front surface 25 of the outlet 24, it may project from the front surface 25. Further, as the lamp switch 26, a touch type switch that is turned on/off when a person touches a fingertip can be adopted, and in the case of the touch type switch, various forms such as a horizontally long form and a vertically long form can be adopted.

The general-purpose connection port 27 is composed of two electrode holes 27a and 27b arranged in parallel vertically, but in the embodiment, the upper and lower electrode holes 27a and 27b have different left and right lengths. This is because some plugs such as the general-purpose plug 28 have a lock function in which the tip of one of the two electrode plates is set to have a wide width. It can be locked and unlocked by twisting.

As clearly shown in FIG. 4 and FIG. 5, the lamp switch 26 is arranged at an intermediate portion of the outlet 24 in the left-right width direction. In other words, the center of the lamp switch 26 is located on the vertical centerline 29 of the outlet 24 (see FIG. 4B). On the other hand, the general-purpose connection port 27 is displaced by a slight dimension E on the side opposite to the left outer plate 5 (inside the shelf device 4) with the vertically long center line 29 interposed therebetween. It is possible to shift the lamp switch 26 to the inside of the shelf device 4 and arrange the general connection port 27 and the lamp switch 26 in a straight line.

As shown in FIG. 5(B), a breaker reset button 31 is provided on the rear surface 30 of the outlet 24 at an upper and lower intermediate height position, and a lamp connection port 32 is provided on both upper and lower sides sandwiching the reset button 31. In addition, the connection port 33 for stationary equipment is formed separately. The two electrode holes 32a, 32b forming the lamp connection port 32 have different left and right lengths, and the upper and lower two electrode holes 33a, 33b forming the other stationary device connection port 33 also have a left and right length. But they are different.

Since the lamp 18 is a stationary device that is always provided in the shelf device 4, the lamp connection port 32 is also a kind of stationary device connection port, but in the present embodiment, the outlet 24 has the lamp switch 26. However, since a dedicated lamp connection port 32 is required, the connection port used for supplying power to devices other than the lamp 18 is indicated as the other stationary device connection port 33.

The lamp connection port 32 is set with the lamp switch 26. Therefore, in order to eliminate an incorrect connection of the lamp plug 34 (see FIG. 3), as shown in FIG. 5(B) and FIG. 7(E), a portion of the lamp connection port 32 is slightly dropped. The concave portion 32c is formed. Instead of the recess 32c, it may be surrounded by a rib or a groove.

Other stationary equipment plugs 35 other than the lamp 18 can be connected to the other stationary equipment connection port 33. Other stationary equipment include electric pencil sharpeners, desktop computers, and auxiliary lighting. Of course, it is possible to connect the other stationary device plug 35 to the general connection port 27, but by connecting the other stationary device plug 35 to the other stationary device connection port 33 on the rear surface 30, It is convenient that the general-purpose connection port 27 on the front surface 25 of the outlet 24 can be used to feed two devices.

As shown in FIG. 6, the outlet 24 basically has a flat plate-shaped substrate 37 and a cover 38 fitted in a state of covering the plate-shaped substrate 37. It is configured. Both the substrate 37 and the cover 38 are made of synthetic resin.

Then, as shown in FIG. 7, on both the board 37 and the cover 38, the lamp switch arranging portions 39a and 39b located on the front and lower intermediate portions and the lamp switch arranging portions 39a and 39b on the front side. Two general electrode placement parts 40a, 40b located above and below, breaker placement parts 41a, 41b located at the rear upper and lower intermediate parts, and a lamp located behind and below the breaker placement parts 41a, 41b. The electrode placement portions 42a and 42b and the electrode placement portions 43a and 43b for other stationary devices located on the rear side and above the breaker placement portions 41a and 41b are formed.

The electrode plate (not shown), the lamp switch 44, and the breaker 45 are sandwiched and held by the substrate 37 and the cover 38. As shown in FIG. 7(A), screw insertion holes 51 pass through the electrode placement portions 40a to 43a of the substrate 37, while as shown in FIG. 7(D) , electrode placement portions of the cover 38 are provided. Female screw holes 52 are formed in 40b to 43b, and the screws inserted into the substrate 37 are screwed into the female screw holes 52 of the cover 38, whereby the substrate 37 and the cover 38 are held integrally.

As shown in FIG. 7(E) and FIG. 4(A), a notch groove 53 facing the substrate 37 is formed on the wall of the rear surface 30 of the cover 38, and the power cable is provided through the notch groove 53. 54 is pulled inside the outlet 24. On the other hand, as shown in FIG. 7A, the substrate 37 is formed with a projection 55 that closes the opening edge of the cutout groove 53, and the presence of the projection 55 causes the cutout groove 53 to be in the state of a hole. ing.

As can be understood from FIG. 7D, the power cable 54 is connected to the breaker 45, and the branch power line 56 branched from the breaker 45 is connected to each general electrode, other stationary equipment electrode, and lamp electrode, respectively. The lamp switch 26 is connected between the breaker 45 and the lamp electrode (the lamp electrode may be interposed between the breaker and the lamp switch 26). The cover 38 is provided with passage forming ribs 57 for organizing and wiring the branch power supply lines 56.

As shown in FIGS. 6(A) and 7(D), female screw holes 58 into which screws can be screwed from the outside are formed at the left and right intermediate portions of the substrate 37 and at two upper and lower portions. The female screw holes 58 are formed at vertically symmetrical positions. In the embodiment, the female screw hole 58 is formed by disposing the hexagon nut (square nut) 60 in the holder portion 59 provided on the substrate 37, and the nut 60 is formed by the tubular boss portion 61 provided on the cover 38. It is held immovable. It is also possible to directly form a female screw on the boss portion (or a simple hole) formed on the substrate 37 without using the nut 60.

Two front and rear mounting holes 62 are formed in the front side of the outer plates 5 and 6 at the same intervals as the vertical intervals of the upper and lower female screw holes 58 in the outlet 24. Then, the positioning pin 63 that substitutes the headed bolt is screwed into the upper female screw hole 58 of the outlet 24, and the positioning pin 63 is fitted into the upper mounting hole 62. The outlet 24 can be held non-rotatably around the horizontal axis.

In other words, if only one screw 64 is fastened and there is no positioning pin 63, the outlet 24 may swivel around the axis of the screw 64 when the plugs 28, 33, 35 are inserted or removed. Although fixing with a screw of a book takes time and effort for attachment and detachment, by using the positioning pin 63 as in the present embodiment, it is possible to hold the outlet 24 non-rotatable even though one screw 64 is fastened. ..

As shown by the alternate long and short dash line in FIG. 2, the outlet 24 can be replaced with the inner surface of the right outer plate 6. In this case, the upper and lower surfaces and the left and right surfaces are inverted by 180° so that the general-purpose connection port 27 is directed toward the front and the female screw hole 58 and the positioning pin 63 are directed toward the right outer side plate 5. It can be fastened with a screw 64 in the posture (the lighting fixture connection port 32 and the stationary device connection port 33 are upside down between left and right use).

Also, when the left outer plate 5 is turned over by 180° and the positioning pin 63 is positioned below, the screw 64 can be inserted into the lower mounting hole 62 by replacing the positioning pin 63 with the upper position. Yes, it is possible to screw the screw 64 into the upper female screw hole 58 with the positioning pin 63 facing down.

As described above, the positioning pin 63 is replaced with a headed bolt, and as shown in FIGS. 6B and 6C, a minus type engagement groove (slipping) 65 is formed on the top surface of the head 63a. As a result, it can be rotated with a flat-blade screwdriver or coin. In addition, the groove 63 is formed on the outer circumference of the head 63a so that the outer circumference of the head 63a has an uneven shape so that it can be easily picked and rotated by a finger (hooking on the finger). Has been improved.).

(3). Summary As described above, since the outlet 24 of the present embodiment is fixed to the inner side surfaces of the outer plates 5 and 6, when storing booklets such as notebooks and texts under the shelf plate 7. The booklets can be stored even in the state where they are brought close to the lower surface of the shelf plate 7. Further, since the outlet 24 is thin and the plugs 28, 33, 35 are directed forward or backward, the storage volume of booklets is not obstructed by the plugs 28, 33, 35. Also in this aspect, the storability of articles such as booklets can be improved.

Further, in the embodiment, the outlet 24 is arranged closer to the front side of the outer plates 5 and 6, while the front surface 25 of the outlet 24 is slightly rearwardly displaced from the front end faces of the outer plates 5 and 6, and therefore, As shown in FIG. 3, the general-purpose plug 28 overlaps with the outer plate 5 (6) in a side view. For this reason, the outer plate 5 (6) serves as a protection member for the general-purpose plug 28 while enhancing the ease of insertion and removal of the general-purpose plug 28, so that an object may accidentally hit the general-purpose plug 28 from the outside. Problems can be prevented or suppressed.

Further, since the general-purpose connection port 27 is displaced (eccentric) inside the shelving device 4, it is possible to prevent the fingers from hitting the outer plates 5 and 6 when the plugs 28, 33 and 35 are inserted and removed. The operability of inserting and removing the plugs 28, 33, 35 is improved, and as shown in FIG. 4(B), a large deformed plug 28' such as a plug with a transformer function can be attached. It is easy to connect an adapter for connecting different kinds of electrodes.

When such a large general-purpose plug 28 is connected, the general-purpose plug 28 may protrude to the inside of the shelving device 4 than the shelving device 4, but the outlet 24 is located closer to the front surface of the outer plates 5 and 6. Therefore, a large storage space can be secured behind the general-purpose plug 28. Therefore, the degree to which the general-purpose plug 28 interferes with the storage of the article can be reduced.

That is, if the front surface of the article is located behind the front surface of the outlet 24, the article can be stored in a state of being stacked on the outlet 24. Therefore, the general-purpose plug 28 is shown in FIG. Even if it projects inward as shown by, the degree to which the left and right inner sides of the outlet 24 can be used as the storage portion is increased.

Further, in the present embodiment, since the general-purpose plugs 28 are arranged above and below the lamp switch 26, the margin below the general-purpose plug 28 located above is lower than that of the general-purpose plug 28 located below. The upper margin also increases. In addition to this, the lamp switch 26 does not protrude from the front surface of the outlet 24, and even if it is a large-sized irregular plug 28' or an adapter for different types of plugs, it should be arranged vertically without interfering with the lamp switch 26. Is possible. Therefore, various plugs 28, 28' having different sizes can be connected with a margin.

In the present embodiment, since the lighting device connection port 32 and the other stationary device connection port 33 are separately arranged on the rear surface 30 of the outlet 24, there are other stationary devices other than the lighting device 18. Also, the other stationary device plug 35 can be held in a state where it is difficult for human hands or objects to touch. For this reason, it is possible to prevent other problems such as accidentally pulling out the stationary equipment plug 35 or deforming it by hitting an object.

In the embodiment, the notch groove 53 for pulling in the power cable 54 is formed close to the side of the outer plate 5(6). Therefore, the retracted portion of the power cable 54 is close to the outer plate 5(6). ing. Then, it is possible to prevent the power cable 54 from getting in the way when the plug 33 for the lamp and the plug 35 for other stationary devices are inserted and removed. Further, it is unlikely that the breaker reset button 31 will interfere with the operation of the bush. When the breaker reset button 31 and the cutout groove 53 are vertically displaced as in the embodiment, the operability of the breaker reset button 31 is further enhanced.

(4). Others The present invention can be embodied in various ways other than the above-described embodiment. As shown by the chain double-dashed line in FIG. 2, the outlet 24 can be fixed to the partition plate 8. The number of connection ports provided in the outlet is not limited, and for example, it is possible to provide three general-purpose connection ports on the front surface of the outlet.

Further, the present invention does not exclude provision of connection ports on the upper surface and the lower surface of the outlet. The provision of both upper and lower surfaces to the connection port of the outlet, when replaced on the outside plate 5 of the left and right in a state of close to the top plate, Oite to both, there is an advantage that can connect a plug from the top into the outlet.

Further, the present invention can be applied to connection of a communication line such as a telephone line or a LAN cable, and can be used together for connection of a power line and a communication line. For example, only the power supply connection port is provided on the front surface and the communication connection port is provided on the rear surface, or only the power supply connection port is provided on the front surface, and the power supply connection port and the communication connection port (for example, LAN cable connection) are provided on the rear surface. It is also possible to provide a mouth.

The shelving system also includes various structures. For example, there may be two or more shelves. It does not have to have drawers or plates. It is also possible to have a structure with a partition plate that reaches the top of the desk. In the embodiment, the screw inserted into the outer plate is screwed into the outlet, but the screw inserted into the outlet can be screwed into the outer plate or the partition plate, and the screw and nut are used to connect the outlet and the outer plate. It is also possible to tighten together.

The present invention can be embodied in an electrical connector such as an outlet. Therefore, it can be used industrially.
