(1) Outline The configuration described below is merely an example of the present invention. The present invention is not limited to the following configuration, and the technical idea according to the present invention is not limited to the following configuration. As long as it does not deviate from the above, various changes can be made according to the design and the like.

  The table tap 1 of the present embodiment includes a long vessel body 10 along one direction. As shown in FIG. 2, the table tap 1 has four outlets to which a plug 101 (first plug) of a power cord such as an electric appliance can be connected. That is, the container 10 has four insertion ports 21 into which the conductors of the insertion plug 101 (the pair of plug blades 101A and the ground terminal 101B) are inserted. The table tap 1 includes connection portions (512, 522, 532) to which the conductors of the insertion plugs 101 inserted into the insertion ports 21 are electrically connected. By connecting the power cord 6 drawn out from the container body 10 to an outlet provided on a wall or the like, for example, AC power from an external power source (for example, commercial AC power source) can be supplied. That is, for example, even if the electric appliance is installed in a place away from the outlet provided on the wall, the electric appliance can be used by inserting the plug 101 of the electric appliance into the insertion port 21 of the table tap 1. AC power can be received via 1. The power cord 6 may have a harness plug connected to the joint box instead of a power plug connected to an outlet provided on a wall or the like.

  The container 10 further has an insertion port 22 (see FIG. 7A). The table tap 1 includes a conductive portion, a connector 7, a conversion circuit, a first substrate 11, and a second substrate 12. The conductive portion electrically connects the external power source and the connection portions (512, 522, 532), and supplies AC power received from the external power source to the conductor of the plug 101. The “conductive portion” referred to here corresponds to, for example, the power cord 6, the conductive portions 511, 521, 531, and the fixing pieces 513, 523, 533. The connector 7 is housed in the container 10 and is electrically connected to the conductor 1020 (see FIG. 13) of the plug 102 inserted into the insertion port 22, whereby DC power is supplied to the conductor 1020. The conversion circuit converts AC power into DC power and supplies the power to the conductor 1020 of the plug 102 through the connector 7.

  In the present embodiment, the “plug 102” inserted into the insertion port 22 is, for example, a USB (Universal Serial Bus) plug 102 (second plug) (see FIGS. 12 to 14). Therefore, the connector 7 is a USB connector 7 (socket) that can be connected by inserting the USB plug 102. In short, the table tap 1 includes USB ports (two as an example) so as to supply DC power for charging a battery built in, for example, a portable terminal device. However, the connector 7 may be, for example, a VGA connector to which a VGA (Video Graphics Array) terminal is connected in addition to the USB connector to which the USB plug 102 is connected.

  In the following description, in the table tap 1, in order to distinguish the insertion port 21 and the insertion port 22, they are referred to as “first insertion port 21” and “second insertion port 22”. Hereinafter, in order to simplify the description, a component for supplying AC power through the first insertion port 21 in the table tap 1 is referred to as a “first block 1A”. Further, in the table tap 1, a component for supplying DC power through the second insertion port 22 is referred to as “second block 1B”. The first block 1A corresponds to a portion on the left side of the container 10 with respect to the two-dot chain line A1 in FIGS. The second block 1B corresponds to a portion on the right side of the two-dot chain line A1.

  In the present embodiment, as shown in FIG. 4, the USB connector 7 is mounted on the first substrate 11, and the electronic component 15 constituting the conversion circuit is mounted on the second substrate 12. The first board 11 and the second board 12 do not overlap each other when viewed from one side in the insertion direction in which the conductor 1020 of the USB plug 102 is inserted. Are housed in the vessel 10 along the line-up direction.

  In this structure, the 1st board | substrate 11 and the 2nd board | substrate 12 are accommodated in the container 10 along with the said alignment direction. Therefore, even if a foreign object (for example, a liquid such as a drink) enters the container 10 from the second insertion port 22, the foreign object directly hits the second substrate 12 on which various electronic components 15 are mounted. Can be suppressed. As a result, it is possible to prevent the reliability from being deteriorated by the foreign matter that has entered the body 10.

The bottom plate 30B also has a locking claw 360 and a locking hole 361 on the inner bottom surface of the housing recess 36C, similarly to the housing recesses 36A and 36B of the bottom plate 30A.

  Here, as shown in FIGS. 5A and 5B, the bottom plate 30B has a pair of drainage ports (drainage) that connect the external space of the vessel 10 and the internal space of the vessel 10 like the drainage ports 18A and 18B of the bottom plate 30A. Hole) 18 (18C, 18C). The pair of drainage ports 18C penetrates in the vertical direction in the vicinity of the front end of the upper end surface of the protruding base 37C, and are aligned with each other in the left-right direction.

  Further, as shown in FIG. 5A, the bottom plate 30B has a plurality of regulating ribs protruding upward on the upper surface thereof. Specifically, the bottom plate 30B has a pair of first restriction ribs 371, a pair of second restriction ribs 372, a pair of third restriction ribs 373, and a pair of fourth restriction ribs 374. These regulating ribs are configured to sandwich the first substrate 11 in the vertical direction together with the plurality of regulating ribs 251 to 254 of the second outer cover 2B, and regulate the displacement of the first substrate 11 in the vertical direction.

  As shown in FIG. 5A, the first restriction rib 371, the second restriction rib 372, the third restriction rib 373, and the fourth restriction rib 374 are arranged in this order from the right end at the front edge and the rear edge of the upper surface of the bottom plate 30B. Is arranged.

  As shown in FIG. 5A, the two first restricting ribs 371 oppose each other in the front-rear direction in the vicinity of the right end of the upper surface of the bottom plate 30B (the left side of the protruding base 37C). Each first restriction rib 371 extends long in the vertical direction and is formed integrally with the first side plate 31B. Each first restriction rib 371 is formed in a T shape when viewed from one side in the vertical direction.

  The vertical dimension of each first regulating rib 371 is larger than the vertical dimension of the first side plate 31B. That is, the upper ends of the first restricting ribs 371 protrude above the upper end of the first side plate 31B (see FIG. 1). Further, as shown in FIG. 1, each first restriction rib 371 has a support recess 371 </ b> A for supporting the first substrate 11 at the upper end thereof. That is, the upper end rear part of the front side first regulating rib 371 and the upper end front part of the rear side first regulating rib 371 are cut out. The first substrate 11 is placed on the bottom surfaces of the support recesses 371A and 371A, so that displacement in the front-rear direction and the downward direction is restricted. Further, as shown in FIG. 1, each first restriction rib 371 has a support protrusion 371B protruding leftward. Since the left end surface in each recess 111 of the first substrate 11 is applied to the support protrusion 371B, the displacement of the first substrate 11 to the right is also restricted.

  As shown in FIG. 5A, the two second restriction ribs 372 face each other in the front-rear direction at a position slightly to the right of the center in the left-right direction of the upper surface of the bottom plate 30B. Each of the second restriction ribs 372 has a strip shape extending long in the vertical direction, and is formed integrally with the first side plate 31B. Each second restriction rib 372 has an upper end protruding upward from the upper end of the first side plate 31B (see FIG. 1). However, the dimension in the vertical direction of the second regulating rib 372 is smaller than the dimension in the vertical direction of the first regulating rib 371, and the distance from the upper surface of the bottom plate 30B to the inner bottom surface of the support recess 371A of the first regulating rib 371. Almost equal.

  The lower surface of the first substrate 11 is in contact with the second regulating ribs 372 and 372. That is, the second restriction rib 372 restricts the downward displacement of the first substrate 11 together with the other restriction ribs 371, 373 and 374.

  Here, as shown in FIG. 4, the second restriction ribs 372 and 372 are slightly on the right side of the right USB connector 7 </ b> B mounted on the first substrate 11 when viewed from one side in the vertical direction. Placed in position. Therefore, the stress received by the first substrate 11 when the USB plug 102 is inserted can be effectively released to the body 10 side. In short, deformation of the first substrate 11 can be suppressed.

  As shown in FIG. 5A, the two third restriction ribs 373 oppose each other in the front-rear direction at a position on the left side of the second restriction rib 372. Each of the third restriction ribs 373 has a strip shape extending long in the vertical direction, and is formed integrally with the first side plate 31B. The vertical dimension of the third regulating rib 373 is substantially the same as the vertical dimension of the second regulating rib 372. The lower surface of the first substrate 11 is in contact with the third regulating ribs 373 and 373. That is, the third restriction rib 373 restricts the downward displacement of the first substrate 11 together with the other restriction ribs 371, 372 and 374.

  Here, as shown in FIG. 4, the third regulating ribs 373 and 373 are arranged at positions between the USB connectors 7A and 7B mounted on the first substrate 11 when viewed from one side in the vertical direction. Has been. Therefore, the stress received by the first substrate 11 when the USB plug 102 is inserted can be effectively released to the body 10 side. In short, the third restriction rib 373 can suppress the deformation of the first substrate 11 together with the second restriction rib 372.

  As shown in FIG. 5A, the two fourth restriction ribs 374 oppose each other in the front-rear direction near the center in the left-right direction of the upper surface of the bottom plate 30B. Each fourth restriction rib 374 extends long along the vertical direction and is formed integrally with the first side plate 31B. Each fourth restriction rib 374 is formed in a T shape when viewed from one side in the vertical direction.

  The upper ends of the fourth regulating ribs 374 protrude upward from the upper end of the first side plate 31B (see FIG. 1). Furthermore, as shown in FIG. 1, each fourth regulating rib 374 has a support recess 374 </ b> A that supports the first substrate 11 at its upper end. That is, the upper end rear part of the front side fourth regulating rib 374 and the upper end front part of the rear side fourth regulating rib 374 are cut out. The first substrate 11 is placed on the bottom surfaces of the support recesses 374A and 374A, so that the displacement in the front-rear direction and the downward direction is restricted. Furthermore, as shown in FIG. 1, each fourth regulating rib 374 has a support protrusion 374B that protrudes to the right. Since the right end surface in each recess 112 of the first substrate 11 is in contact with the support protrusion 374B, the leftward displacement of the first substrate 11 is also restricted.

  Further, as shown in FIG. 4, the fourth regulating ribs 374 and 374 are arranged at a position slightly left of the USB connector 7A mounted on the first substrate 11 when viewed from one side in the vertical direction. Has been. Therefore, the stress received by the first substrate 11 when the USB plug 102 is inserted can be effectively released to the body 10 side. In short, the fourth restriction rib 374 can suppress deformation of the first substrate 11 together with the other restriction ribs 372 and 373.

  Here, as shown in FIG. 5A, the bottom plate 30B of the present embodiment has a third convex wall 173 on its lower surface. The third convex wall 173 is formed so as to protrude upward from the lower surface of the bottom plate 30B. The 3rd convex wall 173 comprises the partition 17 with the 1st convex wall 171 and the 2nd convex wall 172 of the 2nd outer cover 2B. The third convex wall 173 is formed in a substantially rectangular plate shape when viewed from one side in the left-right direction. The third convex wall 173 is formed so that its upper end protrudes above the upper end of the first side plate 31 </ b> B and is disposed above the upper surface of the first substrate 11. For example, the vertical dimension of the third convex wall 173 is slightly larger than the vertical dimension of the first regulating rib 371.

  The lower part of the front end and the lower part of the rear end of the third convex wall 173 are formed integrally with the first side plates 31B and 31B, respectively. The third convex wall 173 has depressions recessed downward at the front end and the rear end, respectively, and the second portion 171B of the first convex wall 171 and the second convex wall 172 are fitted into these depressions. Yes. The partition wall 17 constituted by these convex walls 171 to 173 is provided between the first substrate 11 and the second substrate 12 in the arrangement direction (left-right direction) in which the first substrate 11 and the second substrate 12 are arranged. (See FIG. 4). The partition wall 17 has an insertion port 174 that penetrates in the left-right direction. A plurality of lead wires 121 that electrically connect the input end of the first substrate 11 and the DC output end of the second substrate 12 are wired so as to pass through the insertion opening 174.

  Furthermore, as shown in FIG. 5A, the bottom plate 30B has seven support ribs 375 that protrude upward in a region on the left side of the third convex wall 173 on the top surface thereof. Of the seven support ribs 375, two are the front first side plate 31B, two are the rear first side plate 31B, two are the third convex walls 173, and the last is the boss 311, Each is integrally formed. None of the seven support ribs 375 extends to the upper end of the first side plate 31B, and is sufficiently short compared to the vertical dimension of the first side plate 31B (for example, about half the size of the first side plate 31B). have. In other words, the support rib 375 has a dimension that is sufficiently shorter than the dimension in the vertical direction of each of the second restriction rib 372 and the third restriction rib 373 on which the first substrate 11 is placed.

  The seven support ribs 375 are configured to sandwich the second substrate 12 placed on the upper end thereof in the vertical direction together with the five extension ribs 255 of the second outer cover 2B. In short, the support rib 375 and the extension rib 255 regulate the displacement of the second substrate 12 with respect to the vertical direction. Further, since the front end and the rear end of the second substrate 12 are in contact with a plurality of small protrusions slightly protruding inward from the first side plates 31B, the displacement in the front-rear direction of the second substrate 12 is also reduced. It is regulated. Furthermore, since the right end of the second substrate 12 is in contact with the third convex wall 173 of the partition wall 17 and the left end thereof is in contact with the boss 311, displacement of the second substrate 12 in the left-right direction is also restricted.

  In short, the container 10 of the present embodiment supports the first substrate 11 and the second substrate 12 in a state where the first substrate 11 and the second substrate 12 are arranged in the left-right direction, and further, the first substrate 11 and the second substrate 12 are accommodated by the partition wall 17. It is configured to divide the space that is being separated. Further, in terms of the height position in the vertical direction, the first substrate 11 is supported at a position higher than the second substrate 12 in the vessel body 10. Thereby, the two USB connectors 7 mounted on the first substrate 11 are opposed to the second insertion port 22 as close as possible. On the other hand, since the second substrate 12 is arranged as close to the bottom plate 30B as possible, a space capable of accommodating a plurality of electronic components 15 mounted on the upper surface of the second substrate 12 is formed in the body 10. Has been.

(2.3.5) Slit and Guide Groove As shown in FIG. 1, the outer body 3 has a fitting protrusion 312 that slightly protrudes upward at the peripheral edge of the opened upper surface. The fitting protrusion 312 is formed over the entire periphery. The fitting protrusion 312 is provided inside the outer surface of the outer body 3 (for example, the outer surface of the first side plate 31B). The fitting projection 312 is fitted into the outer cover 2 from the open lower surface of the outer cover 2 so that the outer surface of the outer body 3 and the outer surface of the outer cover 2 are substantially flush with each other.

  Here, as described above, each first side plate 21 </ b> B of the second outer cover 2 </ b> B has a recess 280 in the second end surface 2003. However, the fitting protrusion 312 is configured to be disposed inside the vessel body 10 relative to the recess 280 when viewed from one side in the vertical direction. In other words, a part of the fitting protrusion 312 is exposed through the recess 280 (see FIG. 7B). In short, the outer cover 2 and the outer body 3 are combined to form a guide groove 28 that is elongated in the left-right direction and is recessed inward.

  Further, as described above, the first side plates 21B of the second outer cover 2B are provided with the notches 270 and 270 that are recessed further upward than the upper surface in the recess 280. However, as shown in FIG. 7B, the fitting protrusion 312 does not extend upward enough to close the notch 270 when viewed from one side in the front-rear direction. Therefore, the outer cover 2 and the outer body 3 are combined to form a slit 27 that penetrates the side plate of the container body 10 in the thickness direction.

(2.3.6) Cover and Elastic Material The pair of covers 8 are the same molded product, and have the same shape and the same dimensions as each other. Each cover 8 is formed of a thermoplastic resin such as an ABS resin. Each cover 8 is attached to the container body 10, between a first position that covers the second insertion port 22 to be covered and a second position that exposes the second insertion port 22. The body 10 is configured to be slidable. In the present embodiment, the number of the second insertion ports 22 is two, and the number of the covers 8 is also two. That is, the number of the second insertion ports 22 to be covered by each cover 8 is one. Hereinafter, the cover 8 that covers the left second insertion port 221 is called “cover 8A”, and the cover 8 that covers the right second insertion port 222 is called “cover 8B”.

  Each cover 8 is configured to be slidable independently of the other cover 8 with respect to the second insertion port 22 to be covered. That is, the cover 8A and the cover 8B are movable independently of each other. Hereinafter, the direction in which the cover 8 slides may be referred to as “slide direction”. The “sliding direction” is a direction along (without intersecting) both a first facing surface 810 (lower surface) of the main body 81 described later and a second facing surface 820 (inner surface) of each side portion 82. . In the present embodiment, the “slide direction” corresponds to the left-right direction. Each cover 8 slides between the first position and the second position so that the first facing surface 810 is along the first end surface 2001 and the second facing surface 820 is along the second end surface 2003. Is configured to do.

  Each cover 8 has a main body 81 and a pair of side portions 82 (82A, 82B), as shown in FIGS. Further, each cover 8 includes guide ribs 83, 83, hooking claws 84, 84, a first protrusion 85 (protrusion), a pair of second protrusions 86, 86 (protrusion), and a guide piece 87. And a pressing piece 88.

  As shown in FIG. 8B, the main body 81 is formed in a substantially rectangular plate shape when viewed from one side in the vertical direction. As shown in FIG. 8A, the main body 81 is gently curved so as to protrude upward. The first facing surface 810 (lower surface) of the main body 81 faces the first end surface 2001 (upper surface) provided with the second insertion port 22 of the vessel body 10. A mark 80 (see FIG. 10) is provided on the upper surface of the main body 81 to indicate the sliding direction of the cover. The mark 80 is formed, for example, by projecting a part of the upper surface of the main body 81 upward in a triangular shape.

  As shown in FIG. 9, the side portions 82 </ b> A and 82 </ b> B protrude downward from both ends of the main body portion 81 in the front-rear direction. That is, the main body 81 and the side portions 82A and 82B have an inverted U shape as a whole when viewed from one side in the left-right direction. The second facing surface 820 (inner surface) of each side portion 82 faces the second end surface 2003 (outer surface) of the first side plate 21B.

  As shown in FIG. 9, the guide ribs 83, 83 protrude in a direction approaching each other along the front-rear direction at the lower portion of the second facing surface 820 of the side portions 82, 82. Each guide rib 83 is elongated along the left-right direction when viewed from one side in the front-rear direction, and the dimension in the left-right direction is substantially equal to the dimension in the left-right direction of the side portion 82.

  The guide ribs 83 and 83 are fitted in the guide grooves 28 and 28 of the container body 10 extending along the sliding direction. The movement of the cover 8 in the direction intersecting the sliding direction (for example, the vertical direction) along the second end surface 2003 of the first side plate 21B is restricted by the guide groove 28.

  As shown in FIG. 9, the hooking claws 84 and 84 are provided near the upper center of the guide rib 83 in the left-right direction on the second facing surface 820 of the side portions 82 and 82. Each hooking claw 84, 84 protrudes from the second facing surface 820 in a direction approaching each other along the front-rear direction. Each hooking claw 84 has a protruding piece 840 that protrudes downward from its tip. The protruding pieces 840 and 840 of the hooking claws 84 and 84 are respectively hooked on the edges of the slits 27 and 27 of the container 10. Therefore, the movement of the cover 8 in the direction intersecting the sliding direction (for example, the vertical direction) along the second end surface 2003 of the first side plate 21B is further restricted.

  The cover 8A is in the first position when the hooking claw 84 comes into contact with the right end surface in the slit 27, and is in the second position when the hooking claw 84 comes into contact with the left end surface in the slit 27. 27 horizontal dimensions are defined. The cover 8B is in the first position when the hooking claw 84 comes into contact with the left end surface in the slit 27, and is in the second position when the hooking claw 84 comes into contact with the right end surface in the slit 27. The dimensions of the slit 27 in the left-right direction are defined. In short, the movable range of each cover 8 in the left-right direction is limited by the hooking claws 84 and the slits 27.

  As shown in FIG. 9, the first projecting portion 85 is provided at one end of both ends in the sliding direction on the first facing surface 810 of the main body portion 81. On the other hand, the second projecting portions 86, 86 are provided on the other of the two ends on the first facing surface 810 of the main body portion 81. The first projecting portion 85 and the second projecting portions 86 and 86 both project in a direction approaching the first end surface 2001 of the top plate 20B. These protrusions are in contact with each other so as to be slidable on the first end surface 2001 or close to the first end surface 2001 so that they do not slightly contact each other.

  The first projecting portion 85 of the cover 8A is provided at the left end of the first facing surface 810, and the second projecting portions 86, 86 are provided at the right end of the first facing surface 810. On the other hand, the first protrusion 85 of the cover 8B is provided at the right end, and the second protrusions 86 and 86 are provided at the left end of the first facing surface 810. In short, the cover 8A and the cover 8B adopt a configuration that is plane-symmetric in the left-right direction in which they are arranged (see FIG. 10).

  The second protrusions 86 and 86 of each cover 8 are provided at a predetermined interval in the front-rear direction. This predetermined interval is slightly larger than the dimension of the cough portion 23 in the front-rear direction. In short, the second projecting portions 86 and 86 are configured not to be caught by the cough portion 23 around the second insertion port 22 to be covered when the cover 8 slides.

  As shown in FIG. 9, the guide piece 87 protrudes downward on the first facing surface 810 of the main body 81. The guide piece 87 has a substantially rectangular plate shape when viewed from one side in the left-right direction. In the present embodiment, the guide piece 87 is provided at the end of the first facing surface 810 near the side portion 82B among the side portions 82A and 82B (see FIG. 9). Therefore, the guide piece 87 of the cover 8A is disposed at the front end of the first facing surface 810, and the guide piece 87 of the cover 8B is disposed at the rear end of the first facing surface 810, respectively.

  As shown in FIG. 7A, the guide pieces 87 and 87 are fitted in the recesses 242 and 242 of the second outer cover 2B extending along the sliding direction, respectively. Therefore, the movement of the cover 8 in the direction (for example, the front-rear direction) intersecting the sliding direction along the first end surface 2001 of the top plate 20B is restricted by the recess 242.

  As shown in FIG. 9, the pressing piece 88 protrudes downward on the first facing surface 810 of the main body 81. The pressing piece 88 is provided at the center in the left-right direction and the front-rear direction of the first facing surface 810 of the main body 81. The pressing piece 88 has a rectangular plate shape when viewed from one side in the left-right direction. The pressing piece 88 is fitted in the housing part 241 so as to receive an elastic force from the elastic material 13 housed in the housing part 241 of the second outer cover 2B.

  The two elastic members 13 are, for example, helical coil springs. Each elastic member 13 applies to the cover 8 an elastic force through which the cover 8 slides from the second position to the first position through the pressing piece 88. Specifically, the cover 8 </ b> A receives a rightward elastic force from the elastic material 13, and the cover 8 </ b> B receives a leftward elastic force from the elastic material 13. Therefore, when the USB connector 7 is not used, as shown in FIGS. 7A and 7B, the covers 8A and 8B are both maintained in the first position.

  Here, the cover 8A and the cover 8B have one end portions facing each other in the sliding direction. That is, the cover 8A and the cover 8B are attached to the body 10 in a line along the left-right direction so that the right end of the cover 8A and the left end of the cover 8B face each other. In the present embodiment, the right end portion of the cover 8A corresponds to the right end of the main body portion 81 and the pair of side portions 82, and the left end portion of the cover 8B corresponds to the left ends of the main body portion 81 and the pair of side portions 82. . The cover 8A and the cover 8B are separated from the other cover 8 when one cover 8 slides from the first position to the second position, and one cover 8 slides from the second position to the first position. When it does, it is comprised so that the other cover 8 may be approached.

  When both the cover 8A and the cover 8B are in the first position, the left and right dimensions of the slit 27 and the elastic force of the elastic member 13 are set so that the right end and the left end facing each other are aligned with each other. Has been. Further, when both the cover 8A and the cover 8B are in the first position, the right end portion and the left end portion are aligned with each other along the groove 240 of the second outer cover 2B when viewed from one side in the vertical direction. (See FIG. 7A).

(2.4) Assembly Procedure of Outer Cover, Outer Body and Cover Hereinafter, an assembly procedure of the outer cover 2 and the cover 8 with respect to the outer body 3 will be briefly described. However, the 1st board | substrate 11, the 2nd board | substrate 12, the inside body 4B, and the terminal block 5 shall be accommodated in the outer body 3 previously. It is assumed that the electric wires 61 to 63 of the power cord 6 are connected to the terminal block 5 and the distal end portion of the sheath 60 is fitted in the second semicircular groove 320 (see FIG. 4) of the outer body 3. In addition, it is assumed that the three suction portions 9 are also fitted in the three receiving recesses on the lower surface of the outer body 3, respectively. The assembly procedures (A) to (F) described below are merely examples, and may be assembled by a procedure different from the following procedure.

  (A) The assembling worker first fits the elastic members 13 and 13 into the accommodating portions 241 and 241 of the outer cover 2, respectively. At this time, the elastic member 13 is fitted so that the compression direction of the coil spring matches the sliding direction (left-right direction) of the cover 8.

  (B) The assembly operator attaches the cover 8 </ b> A corresponding to the second insertion port 221 of the outer cover 2 to the outer cover 2. Specifically, the cover 8A is gripped so that the tip of the mark 80 of the cover 8A faces left. Then, in a state where the right end of the left elastic member 13 is bent to the left, the cover 8 </ b> A is attached to the first end surface 2001 and the second end surface 2003 of the outer cover 2 while bending the side portions 82 and 82 slightly outward. The cover 8A is fitted into the outer cover 2 so as to be wrapped, and the pressing piece 88 of the cover 8A is inserted into the accommodating portion 241. At this time, the hooking claw 84 of the cover 8A is inserted into the notch 270 as shown in FIG. 7B, and the guide piece 87 of the cover 8A is also inserted into the recess 242 as shown in FIG. 7A.

  In addition, since the through hole is provided in the bottom surface of the housing portion 241, the outer end of the elastic member 13 is bent leftward by inserting the tip of a tool such as a driver from the back side of the outer cover 2 into the insertion hole. The pressing piece 88 of the cover 8A can be inserted from the front side of the cover 2. When the bending of the elastic material 13 is released, the elastic material 13 is elastically restored and the right end pushes the pressing piece 88 to the right, so that the cover 8A is temporarily held by the outer cover 2.

  (C) Subsequently, the assembly operator attaches the cover 8 </ b> B corresponding to the second insertion port 222 of the outer cover 2 to the outer cover 2. Specifically, the cover 8B is gripped so that the tip of the mark 80 of the cover 8B faces right. Then, in a state where the left end of the right elastic member 13 is bent to the right, the cover 8 </ b> B is attached to the first end surface 2001 and the second end surface 2003 of the outer cover 2 while bending the side portions 82 and 82 slightly outward. The cover 8B is fitted into the outer cover 2 so as to be wrapped, and the pressing piece 88 of the cover 8B is inserted into the accommodating portion 241. Similarly to the cover 8A, the hooking claw 84 of the cover 8B is inserted into the notch 270, and the guide piece 87 of the cover 8B is also inserted into the recess 242. When the bending of the elastic material 13 is released, the elastic material 13 is elastically restored and the left end pushes the pressing piece 88 leftward, so that the cover 8B is temporarily held by the outer cover 2.

  (D) The assembly operator inserts the four middle covers 4 </ b> A into the four through holes 201 of the outer cover 2. That is, the hooking portions 204 and 204 at the front edge and the rear edge of each through-hole 201 are inserted into the concave portions 42 and 42 of the middle cover 4A, and the claws 204A of the hooking portion 204 are hooked on the middle cover 4A. As a result, the middle cover 4 </ b> A is attached to the outer cover 2.

  (E) The assembly operator grasps the outer cover 2 with the four middle covers 4A and the covers 8A and 8B attached to the outer cover 2, and opens the lower surface of the outer cover 2 to the outer body 3. Turn to the top surface. Then, the outer cover 2 is fitted into the outer body 3 so that the fitting protrusion 312 protruding over the entire peripheral edge of the upper surface of the outer body 3 enters the outer cover 2.

  (F) Finally, the assembly operator inserts the five screws 103 into the insertion holes 304 of the bosses 302, 303, 303, 310, 311 from the back side of the outer body 3 and screws them. As a result, the tips of the five screws 103 enter the screw holes of the bosses 203, 202, 202, 207, 208 on the outer cover 2 side. Thereby, the assembly of the outer body 3 and the outer cover 2 is completed.

(2.5) Attachment and Removal of USB Plug Hereinafter, attachment and removal of the USB plug 102 with respect to the table tap 1 will be described mainly with reference to FIGS. Here, for example, it is assumed that a user of a mobile terminal device such as a smartphone uses the table tap 1 to charge a battery built in the mobile terminal device.

  The user can selectively connect the USB plug 102 at the tip of the USB cable connected to the mobile terminal device side to one of the USB connectors 7A and 7B of the table tap 1. For example, when the USB plug 102 is connected to the USB connector 7B on the right side, as shown in FIG. 10, the user covers with the fingertip along the direction (right direction) pointed to by the tip of the triangular mark 80 of the cover 8B. Move 8B. Then, the cover 8 </ b> B slides rightward while the pressing piece 88 deflects the elastic material 13 against the elastic force of the elastic material 13 in the housing portion 241. At this time, the guide ribs 83, 83 of the cover 8B move rightward in the guide grooves 28, 28, and the hooking claws 84, 84 also move rightward in the slits 27, 27. Similarly, the guide piece 87 of the cover 8B moves in the recess 242 in the right direction. When the cover 8B slides to the right to some extent, each catching claw 84 hits the right end surface in the slit 27, and thus further movement of the cover 8B in the right direction is restricted.

  In this state, the right second insertion port 222 is exposed to the outside together with the cough portion 23. That is, the movement of the cover 8B from the first position (which covered the second insertion port 222) to the second position (exposing the second insertion port 222) is achieved (see FIG. 10).

  While maintaining this state with the fingertip, the user inserts the conductor 1020 (see FIG. 13) of the USB plug 102 into the second insertion port 222 as shown in FIG. Are electrically connected. Thereafter, when the user removes the fingertip from the cover 8B, the pressing piece 88 of the cover 8B is pushed leftward by the elastic return of the elastic member 13, and the cover 8B moves leftward. However, since the left end of the main body 81 of the cover 8B hits the metal portion 1030 (see FIG. 13) of the USB plug 102, the sliding movement of the cover 8B stops there. This completes the installation of the USB plug 102. At this time, it is desirable that the elastic force of the elastic member 13 is set so that the cover 8B does not press the USB plug 102 too strongly.

  When the charging of the battery of the mobile terminal device is completed, the user slides the cover 8B slightly to the right with the fingertip, and then removes the USB plug 102 from the second insertion port 222 and releases the cover 8B. . The cover 8B automatically returns to the first position (covering the second insertion port 222) by the elastic return of the elastic member 13.

  Although detailed description is omitted, when the user connects the USB plug 102 to the USB connector 7A on the left side, as shown in FIGS. 11 and 13, the tip of the triangular mark 80 of the cover 8A points. The cover 8A may be moved with the fingertip along the direction (leftward). After that, the second insertion port 222 on the left side is exposed to the outside together with the cough portion 23, so that the USB plug 102 and the USB connector 7A are electrically connected by inserting the conductor 1020 of the USB plug 102 into the second insertion port 221. Connected to.

  Needless to say, the user can use the USB connectors 7A and 7B simultaneously as shown in FIG. For example, in a state where the USB plug 102 on the mobile terminal device side is connected to the USB connector 7A, the USB plug 102 on the other mobile terminal device side can be connected to the USB connector 7B.

(2.6) Structure 1 against foreign matter
Hereinafter, the structure of the cover 8 and the body 10 for suppressing the entry of foreign matter (dust, liquid such as drinks, and food waste) from the second insertion port 22 in the table tap 1 will be described. .

  First, when the cover 8 is in the first position, that is, in a state where the cover 8 covers the second insertion port 22, the table tap 1 can prevent the foreign matter from dropping directly to the second insertion port 22. Further, the cover 8 does not simply cover the second insertion port 22 and its periphery. That is, the cover 8 is configured to cover both the first end surface 2001 of the top plate 20B provided with the second insertion port 22 and the second end surface 2003 of the first side plates 21B and 21B. Therefore, it is also suppressed that foreign matter enters the second insertion port 22 from the side (front-rear direction) of the container body 10.

  Further, the cover 8 has a first projecting portion 85 (projecting portion) at one end in the left-right direction, and a pair of second projecting portions 86 and 86 (projecting portions) at the other end. Accordingly, it is possible to prevent foreign matter from entering the second insertion port 22 from the sliding direction (left-right direction) of the container body 10. In particular, when the foreign substance is a liquid such as a drink, when the liquid is applied to the container body 10, the liquid tends to travel on the first end surface 2001 of the top plate 20 </ b> B to the second insertion port 22. , 86 more effectively suppress liquid intrusion.

  On the other hand, the container 10 has a cough portion 23 that protrudes upward from a region surrounding each second insertion port 22 in the first end surface 2001. Therefore, even if the liquid is applied to the container body 10 and travels on the first end surface 2001 of the top plate 20B toward the second insertion port 22, it can be blocked by the damming portion 23. Moreover, since the groove | channel 240 extended along the front-back direction is provided between the 2nd insertion ports 22 and 22, a liquid enters in the groove | channel 240, and it is easy to drain in the front-back direction along the groove | channel 240. FIG. In particular, the groove 240 is disposed immediately below the boundary where the right end and the left end meet when both the cover 8A and the cover 8B are in the first position. Therefore, even if the liquid flows down from a slight gap between the right end portion of the cover 8A and the left end portion of the cover 8B, the liquid is received by the groove 240 immediately below the liquid and is supplied to the second insertion port 22. Can be suppressed.

(2.7) Structure 2 against foreign matter
Hereinafter, the table tap 1 will be described with reference to FIGS. 15A and 15B, focusing on the internal structure of the container 10 with respect to a liquid (foreign matter) such as a drink that has entered the container 10. Dotted arrows B1 to B4 in FIG. 15B simply show the flow of the liquid.

  First, with respect to the first substrate 11, only the USB connector 7 and the display element 14 are mounted on the upper surface, and a relatively low DC voltage such as about 5 V is supplied (low-power-side substrate). Therefore, even if the liquid is applied to the first substrate 11, the USB connector 7 may cause a contact failure. For example, various electronic components may be damaged, or insulation may be reduced to reduce reliability. It is hard to happen.

  On the other hand, with respect to the second substrate 12, AC power (for example, 100V) for conversion to DC power is supplied from the terminal block 5 (high-power side substrate). Various electronic components 15 constituting the conversion circuit are mounted on the second substrate 12 (see FIG. 15A). Therefore, if the liquid is applied to the second substrate 12, various electronic components 15 are easily damaged, or the insulation is lowered to reduce the reliability.

  On the other hand, in the present embodiment, first, the first substrate 11 and the second substrate 12 are not accommodated side by side in the vertical direction in the vessel body 10, but the first insertion port. 21 and the second insertion port 22 are housed side by side along the arrangement direction, that is, the left-right direction. Specifically, when the first substrate 11, the second substrate 12, and the terminal block 5 (connection portions 512, 522, 532) are viewed from one side in the vertical direction, the first substrate 11, the second substrate 12, The terminal blocks 5 are accommodated in the container 10 in a line along the left-right direction in the order. That is, the board directly under the second insertion port 22 is only the first board 11 on which the USB connector 7 is mounted. Therefore, even if a liquid such as a drink enters the container 10 through the second insertion port 22 (dotted line arrow B1), it is possible to avoid a situation in which the liquid is directly applied to the second substrate 12.

  Furthermore, in the present embodiment, the first substrate 11 and the second substrate 12 are not only housed side by side in the left-right direction, but the second substrate 12 is housed in the first substrate 11 by the partition walls 17. It is isolated from the space. Therefore, as long as the liquid level does not enter a large amount of liquid that exceeds the insertion opening 174 of the partition wall 17 (the lead wire 121 passes), the liquid is prevented from flowing into the space in which the second substrate 12 is accommodated. Can do.

  Moreover, the container 10 of this embodiment has 3 sets (a total of six drains) of the drain outlets 18 which are connected with the external space of the container 10, and become a pair. Therefore, the liquid that has entered the container 10 can be discharged from the container 10.

  In particular, the drain ports (drain holes) 18C, 18C are arranged in a direction in which the first substrate 11 and the second substrate 12 are arranged on the bottom plate (second wall portion) of the vessel 10 when viewed from one of the vertical directions. The first substrate 11 is disposed in a region on the side opposite to the second substrate 12 (right end portion). The liquid that has entered the container 10 through the second insertion port 22 flows down on the first substrate 11 downward from the peripheral edge (dotted line arrow B2), and accumulates at the bottom of the container 10. Then, when the liquid accumulates to some extent at the bottom of the vessel 10 and the water level exceeds the upper end surface of the protruding base 37C at the right end of the vessel 10 (dotted arrow B3), the liquid is discharged from the drain ports 18C and 18C. (Dotted arrow B4). Therefore, it is possible to further suppress the liquid from flowing into the space side in which the second substrate 12 is accommodated.

  Further, the drain outlets 18B, 18B are arranged in a region between the second substrate 12 and the terminal block 5 on the bottom plate (second wall portion) of the container 10 when viewed from one side in the vertical direction. . Therefore, even if the liquid flows into the space side in which the second substrate 12 is accommodated, the liquid can be discharged from the drain ports 18B and 18B.

  By the way, in this embodiment, as shown to FIG. 15A and FIG. 15B, each drain outlet 18 is not directly provided in the lower surface of the baseplate 30B of the container 10, but is accommodated in which the adsorption part 9 is accommodated. It is provided in the recess 36. That is, the adsorbing portion 9 is disposed below each drain port 18. Therefore, for example, the suction part 9 can prevent foreign matters such as pins from entering the drain port 18 by mistake and damaging the electronic component 15 and the like in the container body 10.

(3) Modified Examples Below, several modified examples are listed. Hereinafter, the above-described embodiment is referred to as a “basic example”. The modifications described below can also be applied in appropriate combination with the basic examples described above.

  In the basic example, the number of outlets to which the plug 101 of the power cord such as an electric appliance can be connected is four as an example. However, the number of outlets is not particularly limited. In the basic example, the number of the USB connectors 7 and the second insertion ports 22 to which the USB plug 102 can be connected is two as an example. However, these numbers are not particularly limited.

  In the basic example, the cover target of one cover 8 is one second insertion port 22. However, the cover object of one cover 8 may be two or more second insertion ports 22. Moreover, the number of the 2nd insertion ports 22 is not specifically limited. That is, when the number of the second insertion ports 22 is one, the number of the covers 8 may be one.

  In the basic example, the groove 240 is formed by the first side walls (opposing walls) 233 and 233 of the two cough portions 23 facing each other. However, the groove 240 may be formed by denting a partial region of the first end surface 2001 of the top plate 20 </ b> B, separately from the cough portion 23. However, it is easier to manufacture the vessel 10 if the groove 240 is formed by the cough portion 23 as in the basic example.

  In the basic example, the covers 8A and 8B are slidable independently of each other. However, the covers 8A and 8B may be slidable in conjunction with each other. However, if the covers 8A and 8B are slidable independently of each other as in the basic example, the possibility of foreign matter entering can be further reduced.

  In the basic example, the first substrate 11 is in contact with the second restriction rib 252, the third restriction rib 253, and the fourth restriction rib 254 of the second outer cover 2 </ b> B in the vertical direction. However, the 1st board | substrate 11 may be accommodated in the container 10 in the state slightly separated from these control ribs.

  In the basic example, the first substrate 11 is not in contact with the first reinforcing rib 261 and the second reinforcing rib 262 of the second outer cover 2B in the vertical direction. However, the 1st board | substrate 11 may be accommodated in the container 10 in the state which contacted these reinforcement ribs.

  In the basic example, the second substrate 12 is in contact with the extending rib 255 of the second outer cover 2B in the vertical direction. However, the 2nd board | substrate 12 may be accommodated in the container 10 in the state slightly separated from these extension ribs.

  In the basic example, the protruding piece 840 of each hooking claw 84 of the cover 8 protrudes downward. However, the protruding piece 840 may protrude upward.
