(1) Overview Each drawing described in the following embodiments is a schematic drawing, and the ratio of the size and thickness of each component in each drawing does not necessarily reflect the actual dimensional ratio. Not necessarily.

As shown in FIGS. 1, 3 and 4, the power strip 1 according to this embodiment includes a body 40, a cover 50, and an outlet block A1. The body 40 has an opening 40A and an internal space SP1 connected to the opening 40A, and is elongated in the first direction D1 (see FIG. 2).

The cover 50, as shown in FIG. 2, has an insertion opening 21 into which the conductor 202 of the plug 200 is inserted, and covers the opening 40A. The outlet block A1 is accommodated in the internal space SP1 and electrically connected to the conductor 202 inserted from the receptacle 21. As shown in FIG. That is, the table tap 1 is a device into which a (plug) plug 200 can be inserted and which supplies power to the plug 200 inserted through the outlet block A1. As shown in FIG. 2, the table tap 1 has three sockets 2 (outlets) to which plugs 200 (first plugs P1) of power cords 201 pulled out from electrical equipment or the like can be connected. ing. That is, the table tap 1 can be inserted with up to three first plugs P1 at the same time. However, the number of outlets 2 is not limited to three.

The cover 50 has three insertion openings 21 (21A). Each insertion port 21A has three insertion holes 21a, 21b, 21c into which the plurality of conductors 202 of the first plug P1 are inserted. Here, the multiple conductors 202 of the first plug P1 include a pair of electrodes (plug blades or round pins) 202A and one ground terminal 202B.

In this embodiment, the plug 200 includes a second plug P2 in addition to the first plug P1. That is, the plug 200 includes a USB (Universal Serial Bus) plug (second plug P2). The outlet block A1 includes a USB connector C1 to which the conductor 202 (202C) of the second plug P2 is electrically connected to supply DC power to the conductor 202C. Here, the table tap 1 has two USB connectors C1, as shown in FIG. 2, and up to two second plugs P2 can be inserted at the same time. However, the number of USB connectors C1 is not limited to two. The cover 50 has two insertion openings 21 (21B) for inserting the second plugs P2. The USB connector C1 is a socket into which the second plug P2 can be inserted and connected. In short, the table tap 1 has a USB port so as to supply DC power for charging a battery built in, for example, a mobile terminal device.

AC power can be supplied from an external power supply (for example, a commercial AC power supply) by connecting the power cable 5 pulled out from the body 40 to, for example, an outlet provided on a wall or the like. In other words, even if the electrical equipment is installed in a place away from the outlet provided on the wall, by inserting the plug 200 into the socket 21 of the power strip 1, the electrical equipment can be supplied with AC power through the power strip 1. (In the case of the outlet 21B, it can receive DC power). The power cable 5 may have a harness plug connected to a joint box instead of a power plug connected to an outlet provided on a wall or the like.

Here, the body 40 of this embodiment has at least one wall portion 60 along the second direction D2 intersecting the first direction D1 on the bottom surface 400 of the internal space SP1. Here, as an example, the number of wall portions 60 is two (see FIG. 3). However, the number of wall portions 60 is not limited to two.

As shown in FIGS. 1 and 6, the wall portion 60 has a first portion 61 contacting a portion of the outlet block A1 and a height relative to the bottom surface 400 in the direction D3 in which the bottom surface 400 and the cover 50 are arranged side by side. and a second portion 62 lower than the first portion 61 .

According to this configuration, there is a high possibility that a foreign object that has entered the table tap 1 will pass through the gap G1 (see FIG. 1) surrounded by the first portion 61 and the second portion 62 . In other words, by securing the path for foreign matter, it is possible to reduce the possibility of foreign matter coming into contact with the outlet block A1. Therefore, it is possible to suppress deterioration in electrical reliability when foreign matter enters. In the following description, it is assumed that foreign matter that enters the table tap 1 is, for example, "liquid" such as water (including water droplets, condensed water, etc.) or beverages. However, the foreign matter may be solid matter such as dust or food dregs in addition to the liquid.

As shown in FIG. 1, the body 40 includes a pair of inner side surfaces 401 (corresponding to the inner surfaces of the left side wall 42 and the right side wall 43 here) facing each other in the second direction D2 via the internal space SP1.

The bottom wall 41 is in the shape of an oblong disk elongated in the front-rear direction. The left side wall 42 and the right side wall 43 rise upward from both ends of the bottom wall 41 in the short direction (horizontal direction). The front side wall 44 and the rear side wall 45 rise upward from both ends of the bottom wall 41 in the longitudinal direction (front-rear direction).

The front wall 44 is curved, for example, in a semi-cylindrical shape that protrudes forward along the arc shape of the front end of the bottom wall 41 . The rear wall 45 is, for example, curved in a semi-cylindrical shape that protrudes rearward along the arc shape of the rear end of the bottom wall 41 .

The outline of the opening of the through hole 4 is, for example, circular. The entire perimeter of the contour of the opening of the through hole 4 is closed. Since the perimeter of the through hole 4 is closed, the strength and rigidity of the body 40 are less likely to decrease.

As shown in FIG. 1, the body 40 has an outer peripheral edge portion 40C and an inner peripheral edge portion 40D as the peripheral edge portion 40B of the opening 40A. The outer peripheral edge portion 40C is the outer half of the peripheral edge portion 40B in the width direction, and the inner peripheral edge portion 40D is the inner half of the peripheral edge portion 40B in the width direction. The inner peripheral edge portion 40D is one step lower than the outer peripheral edge portion 40C. Thereby, a stepped portion 40E is formed between the outer peripheral edge portion 40C and the inner peripheral edge portion 40D. When the opening 40A of the body 40 is closed by the cover 50, the later-described outer wall portion 51 of the cover 50 is caught on the stepped portion 40E.

Left and right upper end portions of the U-shape of each first rib 6A extend to the vicinity of the peripheral edge portion 40B.

As shown in FIG. 5B, the five first ribs 6A are arranged so as to partition adjacent partitioned regions in the second to seventh partitioned regions 15B to 15G. Of the five first ribs 6A, the frontmost first rib 6A is separated by two fixing portions B1. The third and fourth first ribs 6A among the five first ribs 6A are each separated by one fixing portion B1.

Two second ribs 6B protrude upward from the bottom surface 400 . The two second ribs 6B are arranged side by side in the front-rear direction and are displaced from each other in the left-right direction. Each second rib 6B has a rectangular plate shape elongated along the first direction D1 when viewed along the second direction D2. The front second rib 6B of the two second ribs 6B extends from the partition wall Q1 to the rearmost first rib 6A of the five first ribs 6A. However, the front second rib 6B is separated by two fixing portions B1. The rear second rib 6B of the two second ribs 6B extends from the rearmost first rib 6A of the five first ribs 6A to the first sandwiching wall J1.

The pair of third ribs 6C are arranged in a region corresponding to the seventh partitioned region 15G on the pair of inner side surfaces 401 (the inner surfaces of the left side wall 42 and the right side wall 43). The pair of third ribs 6C are opposed to each other in the second direction D2. The pair of third ribs 6C protrude from the pair of inner side surfaces 401 toward each other (inward). The pair of third ribs 6C has a long plate-like shape extending along the alignment direction D3 when viewed along the first direction D1, and extends from the vicinity of the bottom surface 400 to the vicinity of the peripheral edge portion 40B.

The five first ribs 6A and the pair of third ribs 6C are arranged such that their upper ends 600 (see FIG. 1) are positioned between the outer peripheral edge 40C and the inner peripheral edge 40D of the peripheral edge 40B of the body 40. is formed. Further, each upper end portion 600 is provided with a recess 601 (see FIG. 1) in which the outer wall portion 51 of the cover 50 is fitted. The bottom surface of the concave portion 601 is flat and connected to the inner peripheral edge portion 40D of the body 40 . Accordingly, when the cover 50 closes the opening 40A of the body 40, the lower end of the outer wall portion 51 of the cover 50 is fitted between the recess 601 and the stepped portion 40E. As a result, positioning of the cover 50 with respect to the body 40 can be achieved.

The first holding wall portion J1 is provided on the back side of the through hole 4 of the body 40 (that is, the back side of the rear side wall 45) in a region of the bottom surface 400 corresponding to the seventh partitioned region 15G. The first sandwiching wall portion J1 protrudes like a wall from the bottom surface 400 to the vicinity of the lower end of the opening of the through hole 4 . The first sandwiching wall J1 is a member that sandwiches the power cable 5 pulled into the body 40 from the outside through the through-hole 4 of the body 40 and the second sandwiching wall J2 of the cover 50, which will be described later. . In this embodiment, the clamping portion 17 that clamps the power cable 5 passing through the through hole 4 is configured by the first clamping wall portion J1 and the second clamping wall portion J2. Since the power cable 5 is clamped by the clamping part 17 , even if the power cable 5 is pulled outside the housing 3 , the tension at that time can be stopped by the clamping part 17 . As a result, even if the power cable 5 is pulled, disconnection between the outlet block A1 in the housing 3 and the power cable 5 can be suppressed.

A plurality of (here, six) fixing portions B1 (boss portions) are portions that are fastened to later-described boss portions 54 of the cover 50 to fix the body 40 and the cover 50 to each other. Each fixing part B1 protrudes upward from the bottom surface 400 . The six fixing portions B1 are provided so as to be distributed over the entire bottom wall 41 .

Further, of the six fixing portions B1, the two fixing portions B1 located substantially in the center are the first rib 6A that separates the fourth partitioned region 15D and the fifth partitioned region 15E, and the fifth partitioned region 15E and the sixth partitioned region. The first ribs 6A that separate the regions 15F are arranged so as to be separated from each other. Among the six fixing portions B1, the two fixing portions B1 located on the rear side are arranged in the seventh partitioned region 15G, and particularly formed integrally with the left and right end portions of the first holding wall portion J1. there is

Each fixing portion B1 is provided with a through hole B10 penetrating along its central axis. The through hole B10 is a hole through which a screw for fixing the body 40 and the cover 50 to each other passes. The through hole B<b>10 further penetrates the bottom wall 41 and connects the internal space SP<b>1 and the outside of the body 40 . In other words, the body 40 has a fixing portion B<b>1 for fixing the cover 50 and the body 40 on the bottom surface 400 .

A plurality of (for example, nine) protrusions L1 contact the lower surface of the core 13 in the outlet block A1 in a state where the cover 50 closes the opening 40A of the body 40 . The projecting portion L1 is a portion that positions the core 13 of the outlet block A1 in the body 40 in the vertical direction together with the later-described positioning portion 55 of the cover 50 . Each protrusion L1 protrudes from the bottom surface 400 in a substantially cylindrical shape. The nine protrusions L1 are divided into three and arranged in each of the fourth to sixth partitioned regions 15D to 15F.

By the way, the body 40 further includes, on the bottom surface 400, a discharge portion E0 for discharging foreign matter (liquid in this case) that has entered the internal space SP1 to the outside of the body 40. As shown in FIG. The discharge part E0 includes a first discharge hole E1 and a second discharge hole E2, as shown in FIG. 5B.

As shown in FIG. 7, the first discharge hole E1 is located at the base end portion (base) of the fixed portion B1 at the boundary between the fourth partitioned area 15D and the fifth partitioned area 15E. The first discharge hole E1 has its opening at the base end portion of the fixing portion B1 in the fourth partitioned area 15D. The first discharge hole E1 connects the internal space SP1 and the outside of the body 40 . The first discharge hole E1 is arranged substantially in the center of the body 40 in the first direction D1, as shown in FIG. 5B.

In front of the opening of the first discharge hole E1 in the bottom surface 400, an arc-shaped wall 402 projects upward when the bottom surface 400 is viewed from the front. Therefore, foreign substances other than liquid are more likely to be blocked by the wall 402 even toward the first discharge hole E1, and a situation occurs in which the first discharge hole E1 is blocked by foreign substances other than liquid. can be suppressed.

The second discharge hole E2 is arranged in the center of the first partitioned area 15A on the bottom surface 400, as shown in FIG. 5B. The second discharge hole E2 connects the internal space SP1 and the outside of the body 40 . Further, the body 40 has a tubular wall 403 on the bottom surface 400 whose outline protrudes upward in the shape of a cannonball when the bottom surface 400 is viewed from the front. A second discharge hole E2 is formed within the area surrounded by the wall 403 . The wall 403 also has a tongue 404 that protrudes from its inner surface and partially covers the opening of the second discharge hole E2 when the bottom surface 400 is viewed from the front. Therefore, foreign substances other than liquid are more likely to be blocked by the wall 403 and the tongue portion 404 toward the second discharge hole E2, and the second discharge hole E2 is blocked by foreign substances other than liquid. It is possible to suppress the occurrence of such a situation as

As shown in FIGS. 3, 4 and 5A, the circuit block H1 includes a first substrate H11 and a second substrate H12 electrically connected to each other by a plurality of lead wires 121, and various components mounted on these substrates. of electronic components 16 .

The first board H11 is a printed wiring board on which a plurality of electronic components 16 forming a conversion circuit are mounted. The first substrate H11 is arranged in the third partitioned region 15C. The conversion circuit, for example, uses AC power (for example, 100 V) received from the electrode units 10A and 10B to generate a high-frequency AC voltage, and then generates a DC voltage that is rectified and smoothed by diodes, electrolytic capacitors, and the like. Then, the conversion circuit outputs a stabilized DC voltage (for example, 5 V) by performing switching adjustment on the generated DC voltage. In short, the conversion circuit is configured to convert AC power from the electrode units 10A and 10B into DC power. A pair of AC input terminals of the conversion circuit are electrically connected to electrode sections 10A and 10B via lead wires 120 and 120, respectively, as shown in FIG. The conversion circuit supplies a stabilized DC voltage of 5V to the second substrate H12 through the DC output terminal.

The second substrate H12 is arranged in the first partitioned region 15A. Each USB connector C1 is a connector (socket) connectable with a second plug P2 (for example, a USB type A plug). The conductor 202C of the second plug P2 is electrically connected to the USB connector C1 to supply DC power to the conductor 202C. However, the type of USB connector is not particularly limited. In this embodiment, the pair of USB connectors C1 are arranged on the second substrate H12 so that their directions are aligned. That is, the plastic substrates on which the four terminals (VBUS, −DATA, +DATA, GND) in the pair of USB connectors C1 are formed are oriented along the horizontal direction. A power terminal (VBUS) and a ground terminal (GND) of each USB connector C1 are connected by soldering to wiring conductors (for example, copper foil) formed on the second substrate H12.

Cut off. The cut-off switch S1 may have a contact inserted in the middle of the electric wire 5A electrically connected to the electrode portion 10A to conduct or cut off the electric wire 5A. The cut-off switch S<b>1 can manually switch the state of the contact through the operation part exposed from the exposure window 18 . In addition, when a current exceeding a predetermined current value (that is, an overcurrent) flows through the electric wire 5B, the cutoff switch S1 automatically switches the contact from the closed state to the open state to cut off the energization of each electric wire 5B ( overcurrent protection function).

(2.7) Path of Foreign Matter By the way, in the table tap 1, for example, foreign matter (liquid here) enters the housing 3 via the plurality of insertion openings 21 (21A, 21B) of the cover 50. intrusion is possible.

For example, if a foreign object enters the housing 3 through the two insertion openings 21B that face the two USB connectors C1, the foreign object falls onto the upper surface of the second substrate H12 in the first partitioned area 15A. Become. Even if the liquid splashes on the second substrate H12 (substrate on the weak current side), it will only cause a contact failure in the USB connector C1. Situation is unlikely.

The foreign matter falls below the second substrate H12 along the upper surface of the second substrate H12. Here, since the second discharge hole E2 of the discharge part E0 is provided under the second substrate H12, the foreign matter that has entered the first partitioned region 15A can be discharged from the second discharge hole E2.

In particular, a relatively tall partition Q1 extending to the lower surface of the second substrate H12 is provided at the boundary between the first partitioned region 15A and the second partitioned region 15B. As a result, foreign matter in the first partitioned region 15A is suppressed from spreading toward the second partitioned region 15B, that is, toward the first substrate H11 (high voltage side substrate).

Further, even if foreign matter enters the second to seventh partitioned regions 15B to 15G, the plurality of ribs 6 provided between the adjacent partitioned regions 15 can prevent the foreign matter from spreading.

Here, of the five first ribs 6A, the two first ribs 6A at the boundary between the fourth partitioned region 15D and the fifth partitioned region 15E and the boundary between the fifth partitioned region 15E and the sixth partitioned region 15F (This is hereinafter referred to as a "specific rib 6X" (see FIG. 6)). Since the two specific ribs 6X have substantially the same shape and size, the front specific rib 6X will be described with reference to FIGS. 1 and 6. FIG.

The specific rib 6X has, as shown in FIG. 1, a wall portion 60 and a pair of extending pieces 63 arranged in the second direction D2 (horizontal direction). In other words, the body 40 has a wall portion 60 along the second direction D2 at the bottom surface 400 of the internal space SP1.

The wall portion 60 is arranged so as to sandwich the fixing portion B1 (boss portion) therebetween in the second direction D2. The wall portion 60 is formed integrally with the fixed portion B1.

Here, the wall portion 60 has a pair of first portions 61 and a pair of second portions 62 . The pair of second parts 62 are arranged so as to sandwich the pair of first parts 61 therebetween in the second direction D2. Here, as an example, the first part 61 (61A) and the second part 62 (62A) on the left side of the fixed part B1 are integrally formed with each other, and their front surfaces are flush with each other. Likewise, their rear faces are flush with each other. A first portion 61 (61B) and a second portion 62 (62B) located on the right side of the fixed portion B1 are formed integrally with each other, and their front surfaces are flush with each other. The rear surfaces are flush with each other.

Each first portion 61 has a rectangular plate shape with its thickness direction facing the front-rear direction. The pair of first portions 61 are arranged in the second direction D2 so as to sandwich the fixing portion B1 therebetween. The pair of first parts 61A and 61B are configured to contact a part of the outlet block A1 in the arranging direction D3 (vertical direction). Here, as an example, "a portion of the outlet block A1" corresponds to the lead portion 80A of the electrode portion 10A and the lead portion 80B of the electrode portion 10B. Specifically, the lead portion 80A is placed on the upper end portion of the first portion 61A, and the lead portion 80B is placed on the upper end portion of the first portion 61B. In short, the lead portions 80A and 80B are restrained from moving downward by the pair of first portions 61, and are stably positioned. Each first portion 61 is arranged on the center side of the bottom surface 400 in the second direction D2. Here, the pair of first parts 61A and 61B are formed integrally with the fixing part B1.

The second portion 62A is arranged between the left inner surface 401 and the first portion 61A, and the second portion 62B is arranged between the right inner surface 401 and the first portion 61B. In other words, each second portion 62 is arranged between one of the pair of inner side surfaces 401 and the first portion 61 . Each second portion 62 has a rectangular plate shape with its thickness direction facing the front-rear direction. The upper end of each second portion 62 is curved upward with distance from the first portion 61 . Each second portion 62 is configured to be lower than the first portion 61 with respect to the bottom surface 400 . The second portion 62A is formed continuously so as to protrude leftward from the lower left edge of the first portion 61A. It has an inverted L shape. The second portion 62B is formed continuously so as to protrude rightward from the lower right edge of the first portion 61B. It is L-shaped.

Since the fixing portion B1 is located slightly leftward from the center in the horizontal direction, the second portion 62B is formed longer than the second portion 62A in the horizontal direction.

Each extending piece 63 has a rectangular plate shape with its thickness direction facing the front-rear direction. Each extending piece 63 is formed integrally with the wall portion 60 on one (corresponding) side of the pair of inner side surfaces 401 and extends toward the opening portion 40A. A left extending piece 63A of the pair of extending pieces 63 is formed continuously with the second portion 62A, and a right extending piece 63B of the pair of extending pieces 63 is formed continuously with the second portion 62B. formed by The upper end portion of each extending piece 63 corresponds to the upper end portion 600 of the first rib 6A described above.

In this embodiment, when a foreign object exceeding the height of the second portion 62 enters the table tap 1, the gap G1 ( (see Figure 1: two locations here). In other words, in the present embodiment, since the wall portion 60 has the first portion 61 and the second portion 62, the path (gap G1) for foreign matter is secured below the outlet block A1, thereby can reduce the possibility of contact with the outlet block A1. Therefore, it is possible to suppress deterioration in electrical reliability when foreign matter enters.

Here, wall 60 is part of rib 6 configured to reinforce the stiffness and strength of body 40 . In other words, the wall portion 60 has a structure that secures the gap G1, a structure that reinforces the body 40, and a structure that positions a portion of the outlet block A1 (the lead portions 80A and 80B).

Further, since the pair of first portions 61 are arranged so as to sandwich the fixing portion B1 therebetween in the second direction D2, they can also serve as portions that reinforce the fixing portion B1. Furthermore, since the extension piece 63 formed integrally with the wall portion 60 is provided, the long body 40 as a whole is further reinforced by the wall portion 60 and the extension piece 63 .

Also, the first portion 61 is arranged on the center side in the second direction D2, and the second portion 62 is arranged between the inner surface 401 and the first portion 61 . As a result, the contact position between the first portion 61 and the electrode portion (10A or 10B) can be set at the center side, and the path for intruding foreign matter can be set at the inner side surface 401 side, thereby preventing deterioration in electrical reliability. can be suppressed further.

In addition, since the fourth partitioned area 15D is provided with the first ejection hole E1 of the ejection part E0, foreign matter that has entered the fourth partitioned area 15D can be ejected from the first ejection hole E1. As a result, deterioration in electrical reliability can be further suppressed.

Of the five first ribs 6A, the rearmost first rib 6A has a wall portion 65 (see FIG. 6) whose height from the bottom surface 400 is substantially equal to the height of the first portion 61. there is A rear end portion of the lead portion 80B is placed on the upper end of the wall portion 65 . Further, of the five first ribs 6A, the two first ribs 6A located in front of the two specific ribs 6X have a height from the bottom surface 400 substantially equal to the height of the second portion 62 ( 6). That is, the wall portion 66 is lower in height than the wall portion 65 .

Due to the configuration of the five first ribs 6A in this way, the amount of foreign matter that has entered the second to sixth partitioned regions 15B to 15F does not exceed the second portion 62 or the wall portion 66. It has a structure that does not easily move to the adjacent partitioned area 15 . However, foreign matter that has entered the fourth partitioned area 15D beyond the second portion 62 or the wall portion 66 is discharged from the first discharge hole E1. In addition, the structure is such that foreign matter that has entered the sixth partitioned region 15F is unlikely to move to the seventh partitioned region 15G side unless an amount of foreign matter exceeding the wall portion 65 enters in a short period of time.
