開關單元70係在外殼72內具備:線圈73、可動鐵片74、觸發桿75、支撐桿76、作動板77、推壓彈簧78、動作構件79、壓接彈簧80、85、L相可動端子板81及L相可動端子部82、N相可動端子板83及N相可動端子部84、L相固定端子板86及L相固定端子部87、以及N相固定端子板88及N相固定端子部89。The
線圈73,係接收來自基板120的動作訊號而被供給電力。藉此,線圈73產生磁力。可動鐵片74,係設於外殼72中接近線圈73後方(圖7中為下方)的位置,並可沿著前後方向Y移動。可動鐵片74係固定於N相可動端子板83的一端部83a。又,N相導線54b之另一端係藉由焊接等與N相可動端子板83之一端部83a電性連接及機械連接。The
觸發桿75係具有略L字形的形狀,並設於外殼72之寬度方向側壁面,且能以軸部75a為中心轉動。觸發桿75之一端部,係配置於能與可動鐵片74卡合的位置。The

作動板77的一端部係抵接並被支撐於支撐桿76之另一端上。作動板77係和一端與操作桿71連接之略U字形的推壓彈簧78之另一端連接,並藉由此推壓彈簧78的推壓力而將作動板77之一端部壓接於支撐桿76之另一端上。One end of the operating
扭轉彈簧90係配置於操作桿71之轉動中心的周圍。如之後所敘述,當開關單元70動作而成為電力切斷狀態時,操作桿71係藉由扭轉彈簧90的偏壓力而轉動,進而如圖8所示,成為突出於插座10之前表面的狀態。The
如圖7所示,動作構件79,係與支撐桿76及作動板77鄰接而配置,並設於外殼72之寬度方向側壁面,且能以軸部79a為中心轉動。動作構件79的後端部(圖7中的下端部)係藉由壓接彈簧80賦予偏壓。藉此,動作構件79係藉由壓接彈簧80,朝圖7中之往逆時針方向轉動的方向賦予偏壓。As shown in FIG. 7, the actuating
動作構件79,其前後方向Y上的略中央部係設為可與L相可動端子板81卡合。L相導線54a的另一端係藉由焊接等與L相可動端子板81之一端電性連接及機械連接。又,L相可動端子部82係藉由例如鉚接等固定於L相可動端子板81的另一端。The actuating
L相可動端子板81,係藉由動作構件79抵抗壓接彈簧85的偏壓力,並被按壓於往順時針方向轉動的位置。藉此,如之後所敘述,當動作構件79藉由壓接彈簧80的偏壓力往逆時針方向轉動時,L相可動端子板81所受到之動作構件79的按壓乃被釋放,因而被壓接彈簧85的偏壓力往上推。The L-phase
又,動作構件79,係按壓並緊抵於N相可動端子板83的中間部分。N相可動端子部84係藉由例如鉚接等固定於N相可動端子板83之另一端部。如之後所敘述,當動作構件79往逆時針方向轉動時,N相可動端子板83會被動作構件79的後端部(圖7中的下端部)往上推,而N相可動端子部84會往前方(圖7中的上方)移動。In addition, the actuating
如圖7所示,L相可動端子部82,係與配置於外殼72內之L相固定端子部87抵接而電性連接。L相固定端子部87,係藉由例如鉚接等固定於L相固定端子板86之一端部。L相固定端子板86係伸出至外殼72的外部。As shown in FIG. 7, the L-phase

如此一來,觸發桿75之一端部會被可動鐵片74所推壓,而往順時針方向轉動,伴隨於此,支撐桿76之另一端部會被觸發桿75所推壓,而往逆時針方向轉動。In this way, one end of the
如此一來,原本被支撐桿76上端所支撐的作動板77之一端部會脫開,作動板77乃被推壓彈簧78的推壓力往後方(圖8中的下方)推壓而處於傾斜的狀態。此時,由於推壓彈簧78的反作用力及扭轉彈簧90的偏壓力,操作桿71乃轉動而使其端部成為突出於插座10之前表面的狀態。In this way, one end of the
由於作動板77已脫離藉由支撐桿76的支撐,故被作動板77往順時針方向按壓而支撐的動作構件79,會因為壓接彈簧80的偏壓力而往逆時針方向轉動。藉此,L相可動端子板81會因為壓接彈簧85的偏壓力而移動,並將L相可動端子部82自L相固定端子部87隔開。與此同時,N相可動端子板83係被往逆時針方向轉動的動作構件79所推壓,而以被往上推的方式移動。藉此,使N相可動端子部84自N相固定端子部89隔開。如此,藉由分別將L相可動端子部82及N相可動端子部84,自L相固定端子部87及N相固定端子部89隔開,而使開關單元70從關閉狀態切換為開啟狀態。其結果,會切斷對刃片承受彈簧插孔塊42a、42b的供給電力,而斷開從插座10經由***插頭供給至家電設備等負載的電力。當異常狀態解除,若以手動操作將操作桿71從圖8所示之狀態回到圖7所示之狀態,則開關單元70內部之各構成構件亦可從圖8所示之狀態恢復到圖7所示之狀態,並從開啟狀態回到關閉狀態。Since the
又,開關單元70,並不限定於上述構成,亦可使用習知的任意構成之電路切斷機構。In addition, the
圖9係顯示將插座10之端子部100之一部分分解之狀態的立體圖。插座10包含端子部100。端子部100係與外部電源線電性連接及機械連接的連接部。FIG. 9 is a perspective view showing a state in which a part of the
端子部100包含:L相固定端子板86、N相固定端子板88、鎖定彈簧92、94及解鎖構件96。L相固定端子板86在從開關單元70的外殼72伸出之另一端部,具有折彎成U字形的L相連接部86a。N相固定端子板88在從開關單元70的外殼72伸出之另一端部,具有折彎成U字形的N相連接部88a。在各相連接部86a、88a的內側係分別配置有鎖定彈簧92、94。藉此,各相連接部86a、88a,係藉由從後方分別***L相及N相之外部電源線的連接端子,而成為所謂可快速連接的速接端子。The
解鎖構件96,可藉由進行推入操作,而使鎖定彈簧92、94從各相連接部86a、88a脫離,其結果,可將L相及N相之外部電源線的連接端子從各相連接部86a、88a取出。The unlocking
又,端子部100包含接地用端子部102。接地用端子部102例如包含接地用端子板104,其係將銅板等金屬板進行衝孔加工及折彎加工而形成。在接地用端子板104之一端部,係與螺絲105螺合,並可使用此螺絲105將接地用外部電線與接地用端子部102連接。在接地用端子板104之另一端,係形成有接地用刃片承受彈簧106。此接地用刃片承受彈簧106,係配置於形成在插座本體蓋體12之頂部蓋體12a之下段的接地端子***口20c內側。藉此,從接地端子***口20c所***之***插頭的接地用端子,係成為與接地用端子板104連接的態樣。In addition, the

溫度感測器54較佳係以熱敏電阻、測溫電阻及熱電偶中的任一者所構成,此情況下,夾子56係使熱敏電阻、測溫電阻及熱電偶中的任一者,與溫度測量對象亦即連接端子部52密接而安裝。又,熱傳導構件亦可夾設於溫度感測器54與連接端子部52之間。熱傳導構件,較佳係例如以具有熱傳導性之片材或油膏等柔軟且薄的構件所構成。可藉由設置如此的熱傳導構件,使溫度感測器54更容易成為與溫度測量對象密接的狀態,而有助於溫度測量精度提高。The
又,在本實施態樣中,雖係列舉夾子56作為用於推壓溫度感測器54,而使其與溫度測量對象亦即連接端子部52密接之推壓構件的使用例,但並不限定於此。亦可使用線圈彈簧、板片彈簧等偏壓構件代替夾子56,將溫度感測器推壓於溫度測量對象。In addition, in this embodiment, although the
圖13係顯示一個刃片承受彈簧插孔塊42a組裝於主體構件44之狀態的立體圖。圖14係顯示一個刃片承受彈簧插孔塊42a與主體構件44的分解立體圖。又,在圖13及圖14中,係省略溫度感測器54及夾子56的圖式說明。FIG. 13 is a perspective view showing a state in which a blade receiving spring

又,刃片承受彈簧插孔塊42a,係一體地包含U字形的彎曲彈簧部49,其分隔並設於包含一對刃片承受片之刃片承受彈簧48的兩側。彎曲彈簧部49具有彎曲部49a,並同時具有一對延伸部49b,該彎曲部49a,係與一對刃片承受片之前端部位於同側,該一對延伸部49b,係從彎曲部49a向一對刃片承受片的基端部側延伸。In addition, the blade receiving spring
刃片承受彈簧插孔塊42a,係收納並配置於主體構件44。主體構件44,係以區劃成四個凹部45的方式形成。在區劃出凹部45的內壁面之中,二個肋部47a係隔著間隔並且在前後方向Y上延伸而形成於位在寬度方向X之中央側的壁面。可藉由該等肋部47a而使主體構件44的強度增加。The blade receives the spring
又,在分隔凹部45的內壁面之中,肋部47b係分別相向並形成於在上下方向Z上相向之內壁面。如圖13所示,該等肋部47b在刃片承受彈簧插孔塊42a組裝於主體構件44時,會成為被位於刃片承受彈簧48之上下方向Z兩側的彎曲彈簧部49的一對延伸部49b夾持的狀態。又,彎曲彈簧部49的彎曲部49a,係抵接於肋部47b的端部。In addition, among the inner wall surfaces of the
如此,可藉由將彎曲彈簧部49的彎曲部49a抵接並組裝於形成在主體構件44之肋部47b的端部,而在正確定位的狀態下,進行刃片承受彈簧插孔塊42a相對於主體構件44的組裝。又,可藉由彎曲彈簧部49之一對延伸部49b成為夾持肋部47b的狀態,而強化刃片承受彈簧插孔塊42a相對於主體構件44所進行的組裝。In this way, by abutting and assembling the
又,若將往寬度方向X的力作用在插拔於插座10的***插頭,則會導致一對刃片承受片塑性變形而異常打開,進而使刃片與刃片承受片的接觸壓力變弱。如此一來,便會產生因接觸不良的微小發光放電等,而成為異常過熱的原因。對此,在本實施態樣的插座10中,藉由使肋部47b被夾持於與刃片承受彈簧48一體形成的彎曲彈簧部49,即使上述開啟力作用於由一對刃片承受片所構成之刃片承受彈簧48,亦可防止或抑制異常打開及變形。In addition, if a force in the width direction X is applied to the plug in and out of the
又,在本實施態樣中,雖係用以彎曲彈簧部49夾持分別形成在與凹部45之上下方向Z相向之二個內壁面之肋部47b的例子加以說明,但並不限定於此。亦能以彎曲彈簧部49之一對延伸部夾持突出形成於凹部45之前後方向Y之內壁面(亦即,凹部45的底面)的肋部,或是亦可藉由一對刃片承受片之基端部(亦即,與前端部相反之一側的端部)夾持突出形成於此底面之肋部的構成。In addition, in this embodiment, although the

安裝於印刷電路板110的溫度感測器112a係與L相固定端子板86接合而設置,安裝於印刷電路板110的溫度感測器112b係與N相固定端子板88接合而設置。接著,藉由溫度感測器112a所測量到之L相固定端子板86的溫度,係經由訊號線114a傳輸至基板120。又,藉由溫度感測器112b所測量到之N相固定端子板88的溫度,係經由訊號線114b傳輸至基板120。The
設於基板120的控制部122,係判斷以溫度感測器112a、112b所測量到之固定端子溫度是否超過既定臨界值溫度。接著,控制部122,在固定端子板86、88中之至少一者的溫度超過既定臨界值溫度時,判斷插座10為過熱狀態,並經由訊號線60c將動作訊號傳輸至開關單元70。藉此,開關單元70會動作而成為開啟狀態,進而切斷對刃片承受彈簧插孔塊42a、42b的供給電力。此處的既定臨界值溫度,可採用和「與藉由上述刃片承受彈簧插孔塊42a、42b的溫度感測器54所測量到之溫度相對照者」相同的值,或是亦可設定為高於該值的值。The
又,在本實施態樣的插座10中,係在刃片承受彈簧插孔塊42a、42b及固定端子板86、88雙方皆配置有溫度感測器,但亦可只在刃片承受彈簧插孔塊42a、42b或固定端子板86、88中之任一者配置溫度感測器。In addition, in the
接著,參照圖16並說明第二實施態樣的插座10A。圖16係第二實施態樣之插座10A之一部分的剖面圖,其相當於圖2所示之第一實施態樣之插座10中之C-C的剖面。又,在圖16中,係省略夾持溫度感測器54之夾子56的圖式說明。Next, referring to FIG. 16, the
如圖16所示,插座10A包含構成插座本體蓋體12之一部分的頂部蓋體12a。頂部蓋體12a係形成有接受***插頭P之刃片S貫通的刃片***口(開口部)20a且由樹脂材料構成的蓋體構件。As shown in FIG. 16, the
在頂部蓋體12a的背面係一體地形成有突出部12c。頂部蓋體12a的突出部12c,係抵接於刃片承受彈簧插孔塊42a的連接部50。突出部12c,亦可係將刃片承受彈簧插孔塊42a推壓於主體構件44,藉此使刃片承受彈簧插孔塊42a相對於主體構件44固定者。此情況下,可省略在第一實施態樣之插座10中的固定構件46。A
在圖16中,雖未以圖式說明另一個刃片承受彈簧插孔塊42b,但形成於頂部蓋體12a之背面的突出部12c亦抵接於刃片承受彈簧插孔塊42b而配置。抵接於刃片承受彈簧插孔塊42b的突出部12c,可與抵接於刃片承受彈簧插孔塊42a的突出部12c一體地形成,亦可分開設置而形成。In FIG. 16, although the other blade receiving
又,插座10A之其他構成,係與上述第一實施態樣之插座10相同。In addition, the other structure of the
在本實施態樣的插座10A中,可在偵測刃片承受彈簧插孔塊42a、42b與***插頭P的刃片S兩者之間的發熱的同時,經由***插頭P的刃片S來偵測***刃片承受彈簧插孔塊42a、42b之***插頭P的發熱。具體而言,當***插頭P未正確***插座10A,在刃片S與刃片承受彈簧插孔塊42a、42b之間會有阻抗等變大的情況,在如此之情況下,可藉由溫度感測器54偵測因刃片承受彈簧插孔塊42a、42b與***插頭P的刃片S之間的發熱所導致的溫度上升。又,由於***插頭P自體隨時間劣化,或在插頭內部的電線壓接不足等熱劣化,會有異常發熱產生之情況。此情況下,經由***插頭P的刃片S或是與***插頭P接觸的頂部蓋體12a,而將熱量從***插頭P傳遞至刃片承受彈簧插孔塊42a、42b。藉此,亦可藉由設於刃片承受彈簧插孔塊42a、42b的溫度感測器54偵測在***插頭P中的異常發熱。In the
又,廣義而言,因為塵埃與濕氣會導致閃爍(微小發光放電)現象發生,而當該閃爍現象持續發生則會導致絕緣劣化,或是因為接觸不良所引起的發熱會使絕緣材料熱劣化,使構成插頭本體的氯乙稀等樹脂材料析出氯化鈣,並因該物質吸收濕氣而導致絕緣破壞;而單純因構造劣化所引起的發熱使導電通路形成之積污導電現象等,也會產生異常發熱。這般異常發熱亦會傳遞至刃片承受彈簧插孔塊42a、42b,而可藉由溫度感測器54進行偵測。In addition, in a broad sense, dust and moisture can cause flicker (micro-luminescence discharge), and when the flicker continues to occur, insulation degradation will occur, or the heat generated by poor contact will cause thermal degradation of the insulating material. , Make the resin material such as vinyl chloride that constitute the plug body precipitate calcium chloride, and cause insulation damage due to the absorption of moisture by this substance; and the pollution and conduction phenomenon formed by the conductive path caused by the heat caused by the structural deterioration, etc. Will produce abnormal heat. Such abnormal heat is also transmitted to the blade receiving
藉由溫度感測器54所偵測到之刃片承受彈簧42a、42b的溫度,係經由訊號線60a、60b傳輸至基板120的控制部122。在刃片承受彈簧插孔塊42a、42b的溫度達到既定臨界值溫度以上的情況下,安裝於基板120的控制部122,係進行下述中至少任一者:使蜂鳴器裝置動作並進行異常通報,或將動作訊號傳輸至開關單元70而切斷對刃片承受彈簧插孔塊42a、42b的供給電力。The blades detected by the
更詳而言之,控制部122,係從刃片承受彈簧插孔塊42a、42b的溫度,導出頂部蓋體12a中與刃片承受彈簧插孔塊42a、42b抵接之突出部12c的溫度。另外,將控制部122中用於判斷異常過熱的既定臨界值溫度,設定成使突出部12c的溫度低於構成頂部蓋體12a之樹脂材料的耐熱溫度。具體而言,上述既定臨界值溫度,係與刃片承受彈簧插孔塊42a、42b中,從溫度感測器54的設定位置到突出部12c抵接部分的熱傳遞有關,係可藉由熱解析而導出,該熱解析係將傳遞至刃片承受彈簧插孔塊42a、42b的熱量與傳熱長度相乘,並將值除以刃片承受彈簧插孔塊42a、42b各自之傳熱部分的剖面積與熱傳導率等。但是,本發明並不限定於此,亦可在實際組裝插座10A中,將加熱器***刃片承受彈簧48而加熱刃片承受彈簧插孔塊42a、42b時,從藉由溫度感測器54所偵測之溫度,與藉由配置於突出部12c之抵接位置之溫度感測器所實測到的溫度,求出兩者的相關性,並依照此相關性,將上述既定臨界值溫度,設定成使突出部12c的溫度低於構成頂部蓋體12a之樹脂材料的耐熱溫度。亦即,所謂兩者的相關性,係指例如當刃片承受彈簧48的溫度為110℃時,由於上述熱量等實體環境,而使突出部12c的溫度成為100℃等的相關性。更具體而言,在以加熱器加熱刃片承受彈簧48時,使該加熱器的加熱溫度變化,並就刃片承受彈簧48與突出部12c的溫度關係,取得複數之圖表而求出溫度相關(函數),或是將其儲存為表格,藉此進行設定。In more detail, the
在本實施態樣的插座10A中,與頂部蓋體12a的樹脂材料相比,主體構件44的樹脂材料,較佳係使用耐熱溫度較高的材料。另一方面,與主體構件44的樹脂材料相比,頂部蓋體12a樹脂材料,較佳係使用表面硬度較高,且耐電痕性較高的材料。具體而言,可使用尿素樹脂作為頂部蓋體12a的材料,可使用聚對苯二甲酸丁二醇酯系樹脂作為主體構件44的材料。In the
又,在本實施態樣的插座10A中,亦可如下階段性地進行異常發熱時之對使用者的通報動作。亦即,藉由溫度感測器54偵測到之溫度,在第一臨界值溫度以上的情況下,使蜂鳴器裝置鳴響,同時點亮異常燈發光部136,但開關單元70維持不動而繼續供給電力。若依如此,則使用者可在電源切斷前注意到插座的異常發熱,而可在開關單元70動作並切斷電源前,例如,在個人電腦採取將作業中的資料暫時保存等處置。其後,若使用者將異常發熱的原因移除而使刃片承受彈簧插孔塊42a、42b的溫度下降之後,將按壓開關132向下按壓進行操作,則可使蜂鳴器音停止,並同時使異常燈發光部136熄滅。又,在插座10A中,藉由溫度感測器54所偵測到之溫度,在高於第一臨界值溫度並達到第二臨界值溫度以上的情況下,使蜂鳴器裝置鳴響,同時使異常燈發光部136點滅,並使開關單元70動作而切斷供給電力。藉此,可防止頂部蓋體12a的熱變形等。In addition, in the
如上所述,在本實施態樣的插座10A中,進行下述中之至少一者:將溫度感測器54設於刃片承受彈簧插孔塊42a、42b,而偵測刃片承受彈簧插孔塊42a、42b與***插頭P的刃片S之間的發熱,或是經由***插頭P的刃片S偵測***於刃片承受彈簧插孔塊42a、42b之***插頭P的發熱。亦即,進行上述偵測中之任一者,或是進行「偵測刃片承受彈簧插孔塊42a、42b與***插頭P之間的發熱,及經由***插頭P的刃片S偵測***於刃片承受彈簧插孔塊42a、42b之***插頭P的發熱」兩者。接著,在該偵到之發熱達到既定臨界值溫度以上的情況下進行熱對策,亦即進行異常通報、及切斷對刃片承受彈簧插孔塊42a、42b的供給電力中之至少任一者。藉此,由於可偵測到***插頭P,或在該***插頭P的刃片S與插座10A的刃片承受彈簧插孔塊42a、42b之間所產生的異常發熱,而進行通報或供給電力的切斷,故可使室內之供給電力的安全性提高。As described above, in the
又,在本實施態樣的插座10A中,較佳係使刃片承受彈簧插孔塊42a、42b的至少一部分抵接於形成有接受***插頭P之刃片S貫通的刃片***口20a、20b且由樹脂材料構成的頂部蓋體12a,而從溫度感測器54之設置位置的溫度,導出頂部蓋體12a中與刃片承受彈簧插孔塊42a、42b抵接之突出部12c的溫度,並將既定臨界值溫度,設定成使該抵接之突出部12c的溫度小於頂部蓋體12a的耐熱溫度。若依如此,則可防止異常發熱所導致之頂部蓋體12a的熱變形等。In addition, in the
又,本揭露並不限定於上述實施態樣及其變形例,理所當然可在本案之申請專利範圍所記載之事項的範圍內進行各種的變形或改良。In addition, the present disclosure is not limited to the above-mentioned embodiments and modifications thereof, and it is of course possible to make various modifications or improvements within the scope of the matters described in the scope of the patent application of the present application.
