(1)概要 於以下實施形態說明的各圖,係示意圖;各圖中之各構成要素的大小及厚度之各自比例,未必反映實際的尺寸比例。(1) Overview The figures in the following description of the embodiments are schematic diagrams; the respective ratios of the sizes and thicknesses of the constituent elements in the figures do not necessarily reflect the actual dimensional ratios.

本實施形態之延長線1,如圖1、圖3及圖4所示,具備:本體40、罩蓋50、以及插線板A1。本體40,具有開口部40A、以及與開口部40A相連的內部空間SP1,並且沿著第1方向D1(參照圖2)呈長條形。As shown in FIG. 1 , FIG. 3 , and FIG. 4 , the extension cord 1 of the present embodiment includes a main body 40 , a cover 50 , and a power strip A1 . The main body 40 has an opening 40A and an internal space SP1 connected to the opening 40A, and has an elongated shape along the first direction D1 (see FIG. 2 ).

罩蓋50如圖2所示,具有供插頭200之導體202插入的插入口21,並覆蓋開口部40A。插線板A1,係容納在內部空間SP1,並與從插入口21插入的導體202電性連接。亦即,延長線1係可供「(插入)插頭200」插入,並經由插線板A1而對插入的插頭200供給電力的裝置。在此,延長線1如圖2所示,具有3口之插座2(outlet;電源插座),該3口之插座2可各自連接從電器等牽出之電源線201的插頭200(第1插頭P1)。也就是說,延長線1,同時最多可插入3個第1插頭P1。但是,插座2的個數,並不限定於3個。As shown in FIG. 2 , the cover 50 has an insertion opening 21 into which the conductor 202 of the plug 200 is inserted, and covers the opening 40A. The patch panel A1 is accommodated in the inner space SP1 and is electrically connected to the conductor 202 inserted from the insertion port 21 . That is, the extension cord 1 is a device that can be inserted into the "(inserted) plug 200" and supplies power to the inserted plug 200 via the power strip A1. Here, as shown in FIG. 2 , the extension cord 1 has a three-port socket 2 (outlet; power socket), and the three-port socket 2 can be connected to the plug 200 (first plug) of the power cord 201 drawn from the electrical appliance or the like. P1). That is to say, the extension cord 1 can be inserted into up to three first plugs P1 at the same time. However, the number of sockets 2 is not limited to three.

罩蓋50,具有3個插入口21(21A)。各插入口21A,具有第1插頭P1之複數個導體202所要插入的3個插入孔21a、21b、21c。在此,第1插頭P1之複數個導體202,包含一對電極(刃片或圓柱插腳)202A、以及1個接地端子202B。The cover 50 has three insertion ports 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 plurality of conductors 202 of the first plug P1 include a pair of electrodes (blade or cylindrical pins) 202A and one ground terminal 202B.

於本實施形態,插頭200除了第1插頭P1以外,亦包含第2插頭P2。亦即,插頭200包含USB(Universal Serial Bus)插頭(第2插頭P2)。插線板A1,包含USB連接器C1,供第2插頭P2之導體202(202C)電性連接,而對導體202C進行直流電力之供給。在此,延長線1如圖2所示,具備2個USB連接器C1,而同時最多可插入2個第2插頭P2。但是,USB連接器C1的個數,並不限定於2個。罩蓋50,具有2個用以插入第2插頭P2的插入口21(21B)。USB連接器C1,係可供第2插頭P2插入而連接的插槽。簡言之,延長線1具備USB埠,可供給直流電力,用以使得內建於例如可攜式終端機等的電池充電。In this embodiment, the plug 200 includes the second plug P2 in addition to the first plug P1. That is, the plug 200 includes a USB (Universal Serial Bus) plug (the second plug P2 ). The power strip A1 includes a USB connector C1 for electrically connecting the conductor 202 ( 202C) of the second plug P2, and supplies DC power to the conductor 202C. Here, as shown in FIG. 2 , the extension cord 1 includes two USB connectors C1, and at most two second plugs P2 can be inserted at the same time. However, the number of the USB connectors C1 is not limited to two. The cover 50 has two insertion ports 21 ( 21B) into which the second plug P2 is inserted. The USB connector C1 is a slot into which the second plug P2 can be inserted and connected. In short, the extension cable 1 has a USB port, which can supply DC power for charging a battery built in, for example, a portable terminal.

從本體40牽出的電源纜線5,藉由連接至例如設於牆壁等之插座,而可以供給來自外部電源(例如商用之交流電源)的交流電力。也就是說,即使電器設置在遠離設於牆壁之插座的場所,仍可藉由將插頭200插入至延長線1之插入口21,而使電器經由延長線1接收交流電力(若是插入口21B,則係直流電力)。電源纜線5,亦可具有並非連接至設於牆壁等之插座的電源插頭,而是連接至接線盒的線束插頭。The power cable 5 drawn from the main body 40 can supply AC power from an external power source (eg, a commercial AC power source) by being connected to a wall socket, for example. That is to say, even if the electrical appliance is installed in a place far away from the wall socket, the electrical appliance can still receive AC power through the extension cord 1 by inserting the plug 200 into the insertion port 21 of the extension cord 1 (if it is the insertion port 21B, is DC power). The power cable 5 may have a harness plug connected to a junction box instead of a power plug connected to a socket provided in a wall or the like.

此處,本實施形態的本體40,在內部空間SP1的底面400,具有沿著與第1方向D1交叉之第2方向D2的至少1個壁部60。在此,作為一例,壁部60的數量係2個(參照圖3)。但是,壁部60的數量,並不限定於2個。Here, the main body 40 of the present embodiment has at least one wall portion 60 along the second direction D2 intersecting with the first direction D1 on the bottom surface 400 of the internal space SP1. Here, as an example, the number of the wall portions 60 is two (see FIG. 3 ). However, the number of the wall portions 60 is not limited to two.

壁部60,如圖1及圖6所示,在底面400與罩蓋50所排列的排列方向D3上,具有與插線板A1之一部分接觸的第1部位61、以及相對於底面400之高度低於第1部位61的第2部位62。As shown in FIGS. 1 and 6 , the wall portion 60 has a first portion 61 that is in contact with a part of the power strip A1 and a height relative to the bottom surface 400 in the arrangement direction D3 in which the bottom surface 400 and the cover 50 are arranged. The second portion 62 is lower than the first portion 61 .

若藉由此構成,則侵入延長線1內的異物,通過第1部位61及第2部位62所圍繞而成的縫隙G1(參照圖1)的可能性會變高。換言之,藉由確保異物的通道,而可以降低異物接觸插線板A1的可能性。因此,可以謀求抑制在異物侵入之情況下的電氣可靠性之降低。於下文中,作為侵入延長線1內之異物,設想係例如水(亦包含水滴、結露水等)或飲料這類的「液體」。可是,除了液體以外,異物亦可係塵埃或食物等的殘渣等固態物質。With this configuration, the foreign matter that has penetrated into the extension cord 1 is more likely to pass through the gap G1 (see FIG. 1 ) surrounded by the first portion 61 and the second portion 62 . In other words, by ensuring the passage of foreign matter, the possibility of foreign matter contacting the wiring board A1 can be reduced. Therefore, it is possible to suppress a decrease in electrical reliability in the event of intrusion of foreign matter. Hereinafter, as the foreign matter intruding into the extension cord 1, it is assumed that it is a "liquid" such as water (including water droplets, dew condensation water, etc.) or beverages. However, in addition to liquid, the foreign matter may be solid matter such as dust or food residues.

(2)詳情 (2﹒1)前提 以下,針對本實施形態之延長線1,參照圖1~圖7,進行詳細說明。於下文中,在沒有特別聲明的情況下,對於延長線1的上下、左右、前後的方向,係使用圖2繪示之上下、左右、前後的箭頭來定義,而進行說明。也就是說,就一例而言,延長線1之機殼3(本體40及罩蓋50)的長邊方向係前後方向,機殼3的短邊方向(寬度方向)係左右方向。插入插頭200之導體202的插入方向係朝下方向。在此,第1方向D1相當於前後方向,第2方向D2相當於左右方向。再者,排列方向D3相當於上下方向。但是,這些方向之用意並不在於限定延長線1的使用方向。再者,標示圖式中之各方向的箭頭,只是為了說明而標記,並不具有實體。於本實施形態,係設想將延長線1放置在書桌等水平面而進行說明,但並非特別有所限定。(2) Details (2﹒1) Premise Hereinafter, the extension cord 1 of the present embodiment will be described in detail with reference to FIGS. 1 to 7 . Hereinafter, unless otherwise stated, the up-down, left-right, and front-rear directions of the extension line 1 are defined by using the arrows showing up-down, left-right, and front-rear directions in FIG. 2 , for description. That is, in one example, the longitudinal direction of the casing 3 (the main body 40 and the cover 50 ) of the extension cord 1 is the front-rear direction, and the short-side direction (width direction) of the casing 3 is the left-right direction. The insertion direction of the conductor 202 inserted into the plug 200 is the downward direction. Here, the first direction D1 corresponds to the front-rear direction, and the second direction D2 corresponds to the left-right direction. It should be noted that the arrangement direction D3 corresponds to the vertical direction. However, these directions are not intended to limit the usage directions of the extension cord 1 . In addition, the arrows which mark each direction in a figure are only marked for illustration, and do not have a substance. In the present embodiment, the extension cord 1 is assumed to be placed on a horizontal surface such as a desk and described, but it is not particularly limited.

(2﹒2)全體構成 延長線1,如圖2所示,具備:沿著第1方向D1呈長條形的機殼3、容納於機殼3的插線板A1(參照圖3)、電源纜線5、以及隔斷開關S1。機殼3係由本體40及罩蓋50所構成。(2﹒2) Overall composition As shown in FIG. 2 , the extension cord 1 includes a casing 3 having an elongated shape along the first direction D1 , a power strip A1 (see FIG. 3 ) accommodated in the casing 3 , a power cable 5 , and a partition switch S1. The casing 3 is composed of a main body 40 and a cover 50 .

(2﹒3)本體 本體40如圖6所示,具有開口部40A、以及與開口部40A相連的內部空間SP1,並且沿著第1方向D1呈長條形。(2﹒3) Main body As shown in FIG. 6 , the main body 40 has an opening 40A and an internal space SP1 connected to the opening 40A, and has an elongated shape along the first direction D1.

具體而言,本體40係由例如PCABS樹脂等的熱可塑性樹脂所形成。本體40,係在前後方向上延伸之大致長方體形狀,並係於頂面具有開口部40A、又有一定深度的盒狀。本體40,如圖1所示,沿著第2方向D2及排列方向D3切割之剖面呈杯形。本體40,在排列方向D3,具有大於罩蓋50的尺寸,因此易於使插線板A1全體容納於本體40側,而提升延長線1的組裝性。Specifically, the main body 40 is formed of thermoplastic resin such as PCABS resin. The main body 40 has a substantially rectangular parallelepiped shape extending in the front-rear direction, and has an opening 40A on the top surface and a box-like shape with a certain depth. As shown in FIG. 1 , the main body 40 has a cup-shaped cross-section cut along the second direction D2 and the arrangement direction D3. The main body 40 has a size larger than that of the cover 50 in the arrangement direction D3 , so that the entire power strip A1 can be easily accommodated on the main body 40 side, thereby improving the assemblability of the extension cord 1 .

本體40如圖2所示,具有:底壁41、左側壁42、右側壁43、前側壁44、以及後側壁45。內部空間SP1,係以底壁41、左側壁42、右側壁43、前側壁44、以及後側壁45所圍繞而成的空間。本體40如圖1所示,包含一對內側面401(在此,相當於左側壁42及右側壁43之內面),其隔著內部空間SP1,而在第2方向D2上彼此相向。As shown in FIG. 2 , the main body 40 has a bottom wall 41 , a left side wall 42 , a right side wall 43 , a front side wall 44 , and a rear side wall 45 . The inner space SP1 is a space surrounded by the bottom wall 41 , the left side wall 42 , the right side wall 43 , the front side wall 44 , and the rear side wall 45 . As shown in FIG. 1 , the main body 40 includes a pair of inner surfaces 401 (here, corresponding to the inner surfaces of the left side wall 42 and the right side wall 43 ), which face each other in the second direction D2 with the inner space SP1 interposed therebetween.

底壁41,係沿著前後方向呈長條形的橢圓板狀。左側壁42及右側壁43,係從底壁41之短邊方向(左右方向)的兩端,朝上方豎立。前側壁44及後側壁45,係從底壁41之長邊方向(前後方向)的兩端,朝上方豎立。The bottom wall 41 is in the shape of an elongated oval plate along the front-rear direction. The left side wall 42 and the right side wall 43 are erected upward from both ends of the bottom wall 41 in the short-side direction (left-right direction). The front side wall 44 and the rear side wall 45 are erected upward from both ends in the longitudinal direction (front-rear direction) of the bottom wall 41 .

前側壁44,係例如沿著底壁41之前端的圓弧形狀而彎曲成朝前方凸出的半圓筒狀。後側壁45,係例如沿著底壁41之後端的圓弧形狀而彎曲成朝後方凸出的半圓筒狀。底壁41,係例如形成為比起頂面之開口部40A小了一圈。因而,左側壁42、右側壁43、前側壁44、及後側壁45,就會從開口部40A側朝向底壁41側,往本體40之內側傾斜。The front side wall 44 is, for example, curved along the arc shape of the front end of the bottom wall 41 into a semi-cylindrical shape protruding forward. The rear side wall 45 is, for example, curved along the circular arc shape of the rear end of the bottom wall 41 into a semi-cylindrical shape protruding rearward. The bottom wall 41 is formed, for example, to be smaller than the opening 40A of the top surface. Therefore, the left side wall 42 , the right side wall 43 , the front side wall 44 , and the rear side wall 45 are inclined toward the inside of the main body 40 from the side of the opening 40A toward the side of the bottom wall 41 .

內部空間SP1,如圖5B所示,具有沿著第1方向D1(前後方向)排列的複數個(例如7個)區劃區域15。以下,有時會將7個區劃區域15,按照從前側往後側的順序,稱為第1~第7區劃區域15A~15G。隔斷開關S1(參照圖5A),係配置於第7區劃區域15G。插線板A1,係配置於第1~第6區劃區域15A~15F。尤其插線板A1當中,對應於3個插座2的零件(一對夾持座70A、70B及夾持座90等),係配置成各自一對一地對應於第4~第6區劃區域15D~15F。插線板A1之中,電路區間H1,係配置成綿延於第1~第3區劃區域15A~15C。As shown in FIG. 5B , the internal space SP1 has a plurality of (for example, seven) divisional regions 15 arranged along the first direction D1 (front-rear direction). Hereinafter, the seven divisional areas 15 may be referred to as the first to seventh divisional areas 15A to 15G in order from the front side to the rear side. The isolation switch S1 (see FIG. 5A ) is arranged in the seventh divisional area 15G. The patch panel A1 is arranged in the first to sixth divisional regions 15A to 15F. In particular, in the patch panel A1, the components corresponding to the three sockets 2 (a pair of clamping bases 70A, 70B and clamping base 90, etc.) are arranged so as to correspond to the fourth to sixth divisional regions 15D on a one-to-one basis, respectively. ~15F. In the patch panel A1, the circuit section H1 is arranged so as to extend over the first to third sub-regions 15A to 15C.

後側壁45,具有在其厚度方向貫穿以供電源纜線5插通的貫穿孔4(參照圖6)。貫穿孔4,係例如設在後側壁45的中央。貫穿孔4之開口的輪廓,係例如圓形。貫穿孔4之開口的輪廓的整圈係閉合。由於貫穿孔4的整圈係閉合,所以不易使本體40之強度及剛性降低。The rear side wall 45 has a through hole 4 (refer to FIG. 6 ) through which the power cable 5 is inserted in the thickness direction. The through hole 4 is provided, for example, in the center of the rear side wall 45 . The outline of the opening of the through hole 4 is, for example, a circle. The entire circle of the outline of the opening of the through hole 4 is closed. Since the entire circle of the through hole 4 is closed, the strength and rigidity of the main body 40 are not easily reduced.

本體40,如圖1所示,作為開口部40A之周緣部40B,具有外周緣部40C、以及內周緣部40D。外周緣部40C,係周緣部40B之寬度方向的外側那一半;內周緣部40D,係周緣部40B之寬度方向的內側那一半。內周緣部40D,比外周緣部40C矮了一截。藉此,會在外周緣部40C與內周緣部40D之間,形成高低差部40E。一旦以罩蓋50封住本體40之開口部40A,罩蓋50的後述之外側壁部51就會卡在高低差部40E上。As shown in FIG. 1 , the main 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 portion 40A. The outer peripheral portion 40C is the outer half in the width direction of the peripheral portion 40B, and the inner peripheral portion 40D is the inner half in the width direction of the peripheral portion 40B. The inner peripheral edge portion 40D is slightly shorter than the outer peripheral edge portion 40C. Thereby, the level difference part 40E is formed between the outer peripheral edge part 40C and the inner peripheral edge part 40D.

在位於底面400的第1排出孔E1之開口的近旁,有一屏障壁402朝向上方突出;從正面觀察底面400時該屏障壁402係圓弧狀。因此,即使有液體以外的異物朝向第1排出孔E1,也有很高的可能性會被屏障壁402攔截,而可以抑制第1排出孔E1被液體以外之異物阻塞之狀況的發生。In the vicinity of the opening of the first discharge hole E1 on the bottom surface 400, a barrier wall 402 protrudes upward; when the bottom surface 400 is viewed from the front, the barrier wall 402 is arc-shaped. Therefore, even if foreign matter other than liquid is directed toward the first discharge hole E1, there is a high possibility that it will be intercepted by the barrier wall 402, and the occurrence of a situation in which the first discharge hole E1 is blocked by foreign matter other than liquid can be suppressed.

第2排出孔E2,如圖5B所示,係配置在位於底面400之第1區劃區域15A內的中央。第2排出孔E2,使得內部空間SP1與本體40的外部相連。再者,本體40於底面400具有筒狀之屏障壁403;從正面觀察底面400時該屏障壁403之輪廓係砲彈狀地往上方突出。第2排出孔E2,係形成在以屏障壁403所圍繞而成的區域內。再者,屏障壁403具有舌部404,從其內面突出,由正面觀察底面400時該舌部404係包覆第2排出孔E2的開口之一部分。因此,即使有液體以外的異物朝向第2排出孔E2,也有很高的可能性會被屏障壁403及舌部404攔截,而可以抑制第2排出孔E2被液體以外之異物阻塞之狀況的發生。As shown in FIG. 5B , the second discharge hole E2 is arranged in the center of the first partition region 15A of the bottom surface 400 . The second discharge hole E2 connects the inner space SP1 to the outside of the main body 40 . Furthermore, the main body 40 has a cylindrical barrier wall 403 on the bottom surface 400 ; when the bottom surface 400 is viewed from the front, the outline of the barrier wall 403 protrudes upward like a cannonball. The second discharge hole E2 is formed in the area surrounded by the barrier wall 403 . Furthermore, the barrier wall 403 has a tongue portion 404 protruding from the inner surface thereof, and the tongue portion 404 covers a part of the opening of the second discharge hole E2 when the bottom surface 400 is viewed from the front. Therefore, even if foreign matter other than liquid is directed toward the second discharge hole E2, there is a high possibility that it will be intercepted by the barrier wall 403 and the tongue portion 404, and the occurrence of the blockage of the second discharge hole E2 by foreign matter other than liquid can be suppressed. .

The door piece 71 is accommodated in a state of being urged by the coil spring 72 . When the pair of electrodes 202A of the first plug P1 is pushed against the door piece 71, the door piece 71 is slid leftward against the pressing force of the coil spring 72, and the first plug P1 is connected. In short, when the socket 2 is not used, the insertion holes 21a and 21b are covered with the door piece 71 .

電路區間H1,如圖3、圖4及圖5A所示,具有藉由複數條引線121而彼此電性連接的第1基板H11及第2基板H12、以及嵌裝於這些基板的各種電子零件16。As shown in FIG. 3 , FIG. 4 , and FIG. 5A , the circuit section H1 includes a first substrate H11 and a second substrate H12 electrically connected to each other by a plurality of leads 121 , and various electronic components 16 embedded in these substrates .

第1基板H11,係印刷配線基板,嵌裝有構成轉換電路之複數個電子零件16。第1基板H11,配置於第3區劃區域15C。轉換電路,係例如使用接收自電極部10A、10B側的交流電力(例如100V),產生高頻的交流電壓後,再藉由二極體及電解電容器等,產生經過整流及平滑化的直流電壓。然後,轉換電路會藉由對於所產生之直流電壓進行切換調整,而輸出穩定化之直流電壓(例如5V)。簡言之,轉換電路係為了使得來自電極部10A、10B側的交流電力轉換成直流電力而構成。轉換電路之一對交流輸入端,如圖3所示,係經由引線120、120,而分別電性連接著電極部10A、10B。轉換電路,會通過直流輸出端,而對第2基板H12側供給已穩定化的5V之直流電壓。The 1st board|substrate H11 is a printed wiring board, and the some electronic component 16 which comprises a conversion circuit is embedded. The first substrate H11 is arranged in the third partition region 15C. The conversion circuit generates a high-frequency AC voltage using, for example, AC power (for example, 100V) received from the electrodes 10A and 10B, and then generates a rectified and smoothed DC voltage through a diode, an electrolytic capacitor, or the like. . Then, the conversion circuit will output a stabilized DC voltage (eg, 5V) by switching and adjusting the generated DC voltage. In short, the conversion circuit is configured to convert the AC power from the side of the electrode parts 10A and 10B into DC power. A pair of AC input terminals of the conversion circuit, as shown in FIG. 3 , are electrically connected to the electrode portions 10A, 10B through lead wires 120 , 120 , respectively. The conversion circuit supplies a stabilized DC voltage of 5V to the second substrate H12 side through the DC output terminal.

第2基板H12如圖3及圖5A所示,係於其頂面(嵌裝面)嵌裝了2個USB連接器C1的印刷配線基板。第2基板H12,係配置於第1區劃區域15A。各USB連接器C1,係可連接第2插頭P2(例如USB Type-A插頭)的連接器(插槽)。第2插頭P2的導體202C會被電性連接至USB連接器C1,而對導體202C進行直流電力之供給。但是,USB連接器的種類並無特別限定。於本實施形態,一對USB連接器C1,會方位一致地排列於第2基板H12。也就是說,已形成一對USB連接器C1內之4個端子(VBUS、-DATA、+DATA、GND)的塑膠基板,會方位一致而使各自皆係沿著左右方向。各USB連接器C1的電源端子(VBUS)與接地端子(GND),各自以銲接而連接至形成於第2基板H12的配線導體(例如銅箔)。各USB連接器C1,係經由第2基板H12的配線導體及複數個引線121等而電性連接至第1基板H11的直流輸出端。在此,第1基板H11相當於強電側基板;第2基板H12則相當於弱電側基板,而被供給5V左右這般較低之直流電壓。As shown in FIG. 3 and FIG. 5A , the second board H12 is a printed wiring board on which two USB connectors C1 are mounted on the top surface (embedding surface). The second substrate H12 is arranged in the first divisional region 15A. Each USB connector C1 is a connector (slot) to which a second plug P2 (eg, a USB Type-A plug) can be connected. 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 the USB connector is not particularly limited. In the present embodiment, the pair of USB connectors C1 are aligned on the second board H12 in the same orientation. That is to say, the plastic substrates on which the four terminals (VBUS, -DATA, +DATA, and GND) of a pair of USB connectors C1 have been formed will be oriented in the same direction so that they are all in the left and right directions. The power supply terminal (VBUS) and the ground terminal (GND) of each USB connector C1 are each connected to a wiring conductor (eg, copper foil) formed on the second substrate H12 by soldering. Each of the USB connectors C1 is electrically connected to the DC output terminal of the first substrate H11 via the wiring conductors of the second substrate H12 and the plurality of lead wires 121 and the like. Here, the first substrate H11 corresponds to the high-current side substrate; the second substrate H12 corresponds to the weak-current side substrate, and is supplied with a low DC voltage such as about 5V.

(2﹒6)隔斷開關 隔斷開關S1,係在電性連接至電極部10B的電線5B之途中,插入接點;藉由使得接點在閉狀態或開狀態間切換,而使電線5B接通或切離。隔斷開關S1,亦可係在電性連接至電極部10A的電線5A之途中,插入接點,而使電線5A接通或切離。隔斷開關S1可經由露出窗18所露出的操作部,而手動切換接點的狀態。再者,只要有既定電流值以上的電流(亦即過電流)在電線5B流動,隔斷開關S1就會使接點自動地從閉狀態切換成開狀態,而切離各電線5B的通電狀態(過電流防止機能)。(2﹒6) Disconnect switch The disconnecting switch S1 is inserted into the contact on the way of being electrically connected to the electric wire 5B of the electrode portion 10B; by switching the contact between the closed state and the open state, the electric wire 5B is connected or disconnected. The disconnect switch S1 may be connected to or disconnected from the electric wire 5A by inserting a contact point in the middle of being electrically connected to the electric wire 5A of the electrode portion 10A. The disconnection switch S1 can manually switch the state of the contact through the operation part exposed by the exposure window 18 . Furthermore, as long as a current of a predetermined current value or more (that is, an overcurrent) flows in the wire 5B, the disconnect switch S1 automatically switches the contact from the closed state to the open state, and cuts off the energized state of each wire 5B ( overcurrent prevention function).

(2﹒7)異物的通道 走筆至此,在延長線1,有可能會有異物(在此設定為液體)經由例如罩蓋50的複數個插入口21(21A、21B)等,侵入至機殼3內。(2﹒7) The passage of foreign matter At this point, the extension cord 1 may have foreign matter (here, liquid) intruding into the casing 3 through, for example, the plurality of insertion ports 21 ( 21A, 21B) of the cover 50 .

例如,當有異物從各自與2個USB連接器C1相向之2個插入口21B侵入至機殼3內的情況下,異物就會落下至位於第1區劃區域15A的第2基板H12之頂面。即使液體潑到第2基板H12(弱電側基板),也只是USB連接器C1發生接觸不良的程度,而不易引發例如各種電子零件破損、或者產生絕緣降低而使可靠性降低的事態。For example, when a foreign object intrudes into the casing 3 from the two insertion openings 21B facing the two USB connectors C1, the foreign object falls on the top surface of the second substrate H12 located in the first partition area 15A . Even if the liquid is spilled on the second substrate H12 (weak side substrate), it is only to the extent that the USB connector C1 has a poor contact, and various electronic components are not easily damaged, or insulation is lowered, which reduces reliability.

異物會經過第2基板H12之頂面,而落下到比起第2基板H12更為下方處。此處,由於在第2基板H12的下方,設有排出部E0的第2排出孔E2,所以侵入了第1區劃區域15A內的異物,就得以從第2排出孔E2排出。The foreign matter passes through the top surface of the second substrate H12 and falls to a lower position than the second substrate H12. Here, since the second discharge hole E2 of the discharge portion E0 is provided below the second substrate H12, foreign matter that has penetrated into the first partitioned region 15A can be discharged from the second discharge hole E2.

尤其在第1區劃區域15A與第2區劃區域15B間的境界,設有延伸至第2基板H12之底面的較高之隔板Q1。其結果,就會抑制第1區劃區域15A內的異物,擴散到第2區劃區域15B側,亦即第1基板H11(強電側基板)側的情形。In particular, at the boundary between the first partitioned region 15A and the second partitioned region 15B, there is provided a relatively high partition Q1 extending to the bottom surface of the second substrate H12. As a result, the foreign matter in the first compartmentalized region 15A is prevented from diffusing to the second compartmentalized region 15B side, that is, the first substrate H11 (high-current-side substrate) side.

再者,即使有異物侵入至第2~第7區劃區域15B~15G內,由於在相鄰之區劃區域15間,設有複數個肋條6,所以可以遏止異物之擴散。Furthermore, even if foreign matter penetrates into the second to seventh divisional regions 15B to 15G, since the plurality of ribs 6 are provided between the adjacent divisional regions 15, the diffusion of the foreign matter can be suppressed.

此處,在5個第1肋條6A之中,將著眼於位在第4區劃區域15D與第5區劃區域15E間的境界、以及位在第5區劃區域15E與第6區劃區域15F間的境界之2個第1肋條6A(以下,會將之稱為「特定肋條6X」(參照圖6))。由於2個特定肋條6X,係彼此大致同形狀、同大小,所以將針對位於前方的特定肋條6X,參照圖1及圖6以進行說明。Here, among the five first ribs 6A, attention will be paid to the boundary between the fourth divisional area 15D and the fifth divisional area 15E, and the boundary between the fifth divisional area 15E and the sixth divisional area 15F. The two first ribs 6A (hereinafter, referred to as "specific ribs 6X" (see FIG. 6 )). Since the two specific ribs 6X have substantially the same shape and size, the specific rib 6X located in the front will be described with reference to FIGS. 1 and 6 .

特定肋條6X如圖1所示,具有壁部60、以及在第2方向D2(左右方向)上排列之一對延伸片63。換言之,本體40在內部空間SP1的底面400,具有沿著第2方向D2的壁部60。As shown in FIG. 1 , the specific rib 6X has a wall portion 60 and a pair of extending pieces 63 arranged in the second direction D2 (left-right direction). In other words, the main body 40 has the wall portion 60 along the second direction D2 on the bottom surface 400 of the inner space SP1.

壁部60配置成在第2方向D2上,將固定部B1(螺絲柱)夾在中間。壁部60,係與固定部B1一體形成。The wall portion 60 is arranged in the second direction D2 so as to sandwich the fixing portion B1 (screw stud). The wall portion 60 is integrally formed with the fixing portion B1.

在此,壁部60分別具有一對第1部位61、以及一對第2部位62。一對第2部位62配置成在第2方向D2上,將一對第1部位61夾在中間。在此,作為一例,位在比起固定部B1更為左側處的第1部位61(61A)及第2部位62(62A),係彼此一體形成,該等之前表面彼此成為一個平面,同樣地該等之後表面彼此成為一個平面。再者,位在比起固定部B1更為右側的第1部位61(61B)及第2部位62(62B),係彼此一體形成,該等之前表面彼此成為一個平面,同樣地該等之後表面彼此成為一個平面。Here, the wall portion 60 has a pair of first sites 61 and a pair of second sites 62, respectively. The pair of second parts 62 are arranged in the second direction D2 so as to sandwich the pair of first parts 61 therebetween. Here, as an example, the first portion 61 ( 61A) and the second portion 62 ( 62A) located on the left side of the fixing portion B1 are integrally formed with each other, and these front surfaces are formed into a flat surface, and similarly The rear surfaces become one plane with each other. Furthermore, the first part 61 (61B) and the second part 62 (62B), which are located on the right side of the fixing part B1, are integrally formed with each other, and the front surfaces become one plane with each other, and similarly the rear surfaces become a plane with each other.

各個第1部位61,係厚度方向朝向前後方向的矩形板狀。一對第1部位61配置成在第2方向D2上,將固定部B1夾在中間。一對第1部位61A、61B,構成為在排列方向D3(上下方向)上,接觸插線板A1之一部分。在此,作為一例,所謂的「插線板A1之一部分」,係相當於電極部10A的導片部80A、及電極部10B的導片部80B。具體而言,導片部80A係載置於第1部位61A的上端部,導片部80B係載置於第1部位61B的上端部。簡言之,導片部80A、80B,係以一對第1部位61而限制住朝向下方的移動,穩定地定位。各個第1部位61,係配置於第2方向D2上的底面400之中央側。在此,一對第1部位61A、61B,係與固定部B1一體形成。Each of the first portions 61 is in the shape of a rectangular plate whose thickness direction is directed in 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. A pair of 1st parts 61A, 61B are comprised so that it may contact a part of the wiring board A1 in the arrangement direction D3 (vertical direction). Here, as an example, the so-called "part of the wiring board A1" corresponds to the lead portion 80A of the electrode portion 10A and the lead portion 80B of the electrode portion 10B. Specifically, the guide piece portion 80A is placed on the upper end portion of the first site 61A, and the guide piece portion 80B is placed on the upper end portion of the first site 61B. In short, the guide pieces 80A and 80B are stably positioned by restricting their downward movement by the pair of first parts 61 . Each of the first parts 61 is arranged on the center side of the bottom surface 400 in the second direction D2. Here, the pair of first portions 61A and 61B are integrally formed with the fixing portion B1.

第2部位62A,係配置於左側的內側面401、與第1部位61A之間;第2部位62B,係配置於右側的內側面401、與第1部位61B之間。換言之,各個第2部位62,係配置於一對內側面401之中的其中一個、與第1部位61之間。各個第2部位62,係厚度方向朝向前後方向的矩形板狀。各個第2部位62的上端,係彎曲成越遠離第1部位61越朝向上方。各個第2部位62,相對於底面400之高度構成為低於第1部位61。第2部位62A,從第1部位61A的左下之邊緣部往左方突出而連續地形成;第1部位61A及第2部位62A,從其正面觀察下,其整體呈反L字形。第2部位62B,從第1部位61B的右下之邊緣部往右方突出而連續地形成;第1部位61B及第2部位62B,從其正面觀察下,其整體呈L字狀。The second portion 62A is arranged between the left inner side surface 401 and the first portion 61A, and the second portion 62B is arranged between the right inner side surface 401 and the first portion 61B. In other words, each second site 62 is arranged between one of the pair of inner surfaces 401 and the first site 61 . Each of the second portions 62 is in the shape of a rectangular plate whose thickness direction is directed in the front-rear direction. The upper end of each second portion 62 is curved so as to be directed upward as it is farther away from the first portion 61 . The height of each second portion 62 with respect to the bottom surface 400 is configured to be lower than that of the first portion 61 . The second portion 62A is formed continuously to protrude leftward from the lower left edge of the first portion 61A. The first portion 61A and the second portion 62A have an inverted L-shape as a whole when viewed from the front. The second portion 62B is formed to protrude rightward from the lower right edge of the first portion 61B, and the first portion 61B and the second portion 62B are L-shaped as a whole when viewed from the front.

由於固定部B1之位置,比起左右方向的中心稍微偏左,所以第2部位62B在左右方向上,形成得比第2部位62A更長。Since the position of the fixing portion B1 is slightly leftward from the center in the left-right direction, the second portion 62B is formed longer than the second portion 62A in the left-right direction.

各延伸片63,係厚度方向朝向前後方向的矩形板狀。各延伸片63在一對內側面401之中的(對應之)其中一個,與壁部60一體形成,而朝向開口部40A延伸出去。一對延伸片63中之左側的延伸片63A,係與第2部位62A連續形成;一對延伸片63中之右側的延伸片63B,係與第2部位62B連續形成。各延伸片63的上端部,相當於上述之第1肋條6A的上端部600。Each of the extending pieces 63 is in the shape of a rectangular plate whose thickness direction is directed in the front-rear direction. Each extension piece 63 is formed integrally with the wall portion 60 on one (corresponding to) one of the pair of inner side surfaces 401 and extends toward the opening portion 40A. The left extension piece 63A of the pair of extension pieces 63 is formed continuously with the second portion 62A; the right extension piece 63B of the pair of extension pieces 63 is formed continuously with the second portion 62B. The upper end portion of each extension piece 63 corresponds to the upper end portion 600 of the first rib 6A described above.

於本實施形態,在高度超過第2部位62之程度的異物侵入延長線1內的情況下,通過各個第1部位61與其隔壁之第2部位62所圍繞而成的縫隙G1(參照圖1;在此係2處)的可能性就會變高。換言之,於本實施形態,由於壁部60具有第1部位61及第2部位62,所以藉由在比起插線板A1更為下側處確保異物的通道(縫隙G1),就可以降低異物接觸插線板A1的可能性。因此,可以謀求抑制在異物侵入之情況下的電氣可靠性之降低。In the present embodiment, when a foreign object with a height exceeding the second portion 62 intrudes into the extension cord 1, each first portion 61 and the second portion 62 of its partition wall pass through the gap G1 (refer to FIG. 1; In this department 2) the possibility will become higher. In other words, in this embodiment, since the wall portion 60 has the first portion 61 and the second portion 62, the foreign matter can be reduced by securing a passage (gap G1) for foreign matter on the lower side than the power strip A1. Possibility to contact patch panel A1. Therefore, it is possible to suppress a decrease in electrical reliability in the event of intrusion of foreign matter.

在此,壁部60係為了補強本體40的剛性及強度而構成之肋條6的一部分。也就是說,壁部60兼具:確保縫隙G1的結構、補強本體40的結構、以及使得插線板A1之一部分(導片部80A、80B)定位的結構。Here, the wall portion 60 is a part of the rib 6 formed to reinforce the rigidity and strength of the main body 40 . That is, the wall portion 60 has a structure for securing the gap G1 , a structure for reinforcing the main body 40 , and a structure for positioning a part of the plug board A1 (the guide pieces 80A, 80B).

再者,由於一對第1部位61係配置成在第2方向D2上將固定部B1夾在中間,所以可兼用作補強固定部B1的部位。更進一步地,藉由設置與壁部60一體形成之延伸片63,而能以壁部60與延伸片63,更為補強長條狀的本體40全體。Furthermore, since the pair of first portions 61 are arranged so as to sandwich the fixing portion B1 in the second direction D2, they can also serve as portions for reinforcing the fixing portion B1. Furthermore, by providing the extension piece 63 integrally formed with the wall portion 60 , the wall portion 60 and the extension piece 63 can further strengthen the entire elongated body 40 .

再者,第1部位61係配置於第2方向D2上的中央側,第2部位62係配置於內側面401與第1部位61之間。其結果,第1部位61與電極部(10A或10B)間的接觸位置會設定在中央側,而可以將侵入之異物所要通過的通道,設定在內側面401側,所以可以更進一步地抑制電氣可靠性之降低。In addition, the 1st part 61 is arrange|positioned at the center side in the 2nd direction D2, and the 2nd part 62 is arrange|positioned between the inner surface 401 and the 1st part 61. As shown in FIG. As a result, the contact position between the first portion 61 and the electrode portion ( 10A or 10B ) can be set on the center side, and the passage through which the foreign matter intruding can pass can be set on the inner side surface 401 side, so that the electric current can be further suppressed. Decreased reliability.

再者,由於在第4區劃區域15D設有排出部E0的第1排出孔E1,所以侵入了第4區劃區域15D內的異物,就可以從第1排出孔E1排出。其結果,可以更進一步地抑制電氣可靠性之降低。Moreover, since the 1st discharge hole E1 of the discharge part E0 is provided in the 4th division area 15D, the foreign matter which penetrated into the 4th division area 15D can be discharged from the 1st discharge hole E1. As a result, the decrease in electrical reliability can be further suppressed.

5個第1肋條6A之中,位在最後方的第1肋條6A,具有壁部65(參照圖6);該壁部65從底面400起算的高度,大致等於第1部位61的高度。在壁部65的上端,載置著導片部80B的後端部。再者,5個第1肋條6A之中,比起2個特定肋條6X更為位於前方的2個第1肋條6A,具有壁部66(參照圖6);該壁部66從底面400起算的高度,大致等於第2部位62的高度。也就是說,壁部66的高度,低於壁部65。Among 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 approximately equal to the height of the first portion 61 . On the upper end of the wall portion 65, the rear end portion of the guide piece portion 80B is placed. In addition, among the five first ribs 6A, the two first ribs 6A which are located more forward than the two specific ribs 6X have a wall portion 66 (see FIG. 6 ); the wall portion 66 is counted from the bottom surface 400 . The height is substantially equal to the height of the second portion 62 . That is, the height of the wall portion 66 is lower than the wall portion 65 .

藉由使得5個第1肋條6A如此這般地構成,而形成以下結構:侵入了第2~第6區劃區域15B~15F內的異物,只要份量沒有多到超過第2部位62或壁部66,就不容易移轉到隔壁的區劃區域15。但是,超過第2部位62或壁部66而進到第4區劃區域15D的異物,會從第1排出孔E1排出。再者,形成以下結構:侵入了第6區劃區域15F內的異物,只要侵入的份量沒有多到在短時間就會超過壁部65,則不容易移轉到第7區劃區域15G側。By configuring the five first ribs 6A in this manner, a structure is formed in which the foreign matter intruding into the second to sixth divisional regions 15B to 15F does not exceed the second portion 62 or the wall portion 66 in amount. , it is not easy to move to the partition area 15 next door. However, the foreign matter that has entered the fourth divisional region 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 the foreign matter that has penetrated into the sixth divisional area 15F is not easily moved to the seventh divisional area 15G side unless the amount of intrusion exceeds the wall portion 65 in a short time.

(3)變形例 上述實施形態,僅為本發明各種實施形態的一種。只要可達成本發明之目的,上述實施形態可因應設計等等而進行各種變更。以下將列舉上述實施形態的變形例。以下所說明之變形例,可適當組合而套用。於下文中,有時會將上述實施形態稱為「基本例」。(3) Modifications The above-described embodiment is only one of various embodiments of the present invention.

For example, the wall portion 60 may be configured in a comb-tooth shape in which the first portions 61 and the second portions 62 are alternately arranged.

於基本例,各個第2部位62,係配置於一對內側面401之中的其中一個、與第1部位61之間。可是,例如圖8所示,亦可對調第2部位62與第1部位61的位置關係。亦即,各個第1部位61,亦可係配置於一對內側面401之中的其中一個、與第2部位62之間,而各個第2部位62係與固定部B1一體形成。In the basic example, each second portion 62 is arranged between one of the pair of inner side surfaces 401 and the first portion 61 . However, for example, as shown in FIG. 8 , the positional relationship between the second portion 62 and the first portion 61 may be reversed.
