200428709 玖、發明說明 (發明說明應敘明：發明所屬之技禅T領域、先前技術、內容、實施方式及圖式簡單說明) 【發明所屬之技術領域】 本發明涉及具備有壓接槽的接線板、將為絕緣包皮電 線的電線壓入接線板的壓接槽來連接的組合式插座。 5【先前技術】 迄今為止，作為信息通訊用的電纜廣泛使用將數對雙 紐線鎧裝地收放的雙紐電纜，提供具備連接雙紐電纜的接 線盒的組合式插座。作為這種接線盒，已知的有設置具有 壓接槽的接線板的接線盒。接線板在一個周邊做成具有開 10 口的壓接槽的二齒叉狀，如果將構成雙紐電纜的各電線壓 入壓接槽，電線的絕緣包皮在壓接槽的周邊被切去’芯線 就被壓接在壓接槽的周邊。也就是說，如第十三圖以及第 十四圖所示的那樣，在接線盒2上豎著設置從接線板24突 出來的面保護接線板24的數個保護壁23，使壓接槽24a 15 與相鄰的保護壁23之間對應來配置接線板24，如第十五 圖所示，將雙紐電纜4的電線5導入相鄰的保護壁23之 間，電線5就被壓入接線板24的壓接槽24a中。另外，壓 接槽24a的寬度設定為比電線5的芯線的直徑小。 這裏，由於需要比較大的力來把電線5壓入壓接槽 20 24a，所以一般使用第十六圖所示的壓擠工具7那樣的專用 工具來將電線5壓入壓接槽24a中。通過使用這種壓擠工 具7，能夠同時進行電線5的壓入和剩餘電線的切斷，具 有使接線作業變得容易的優點。 然而，存在所述壓擠工具7那樣的專用工具價格高昂 Μ續次頁（發明說明頁不敷使用時，請註記並使用續頁） -5- 200428709 發明說明®胃 的問題，對此，提供如第十七圖所示那樣的簡易工具8， 其具備在一對齒間有槽的二齒叉狀的前端部8a。這裏，在 使用第十七圖所示的簡易工具8進行接線作業的場合，利 用前端部8a將電線5壓入壓接槽24a之後，可以將剩餘電 5 線用剪鉗等工具切斷。 第十七圖所示的簡易工具8，與合成樹脂製的壓擠工 具7相比，雖然具有價格低廉的優點，但是，存在對數個 組合式插座在使用上的耐久性低下的問題，為了提高耐久 性，必須用金屬製品構成前端部8a，這相對於簡易工具來 10 說價格將升高。另外，在接線板24和電線5的接線作業中， 在使用第十六圖所示的壓擠工具7或者第十七圖所示的簡 易工具8等專用工具的場合，必須一直攜帶這些專用工具。 這裏，如第十八圖所示，針對能夠將4對8芯的絞合 電纜4的各電線5配置在相鄰的保護壁23之間的接線盒2 15 (也就是說，在該接線盒2上設有8個接線板24)，提供 了以下技術方案：為了分別覆蓋2對接線板24，在安裝有 第十九圖以及第二十圖所示的2個保護蓋3”上，各設置2 對將電線5壓入到壓接槽24a的簡易工具部37 (例如，參 照專利文獻1)，或者，為了覆蓋4對接線板24,在安裝有 20 第二十一圖以及第二十二圖所示的保護蓋3’上，各設置4 對將電線5壓入到壓接槽24a的簡易工具部37。 通過使用所述的保護蓋3’、3”，能夠將數根電線5集 中起來連接到接線板24上，而且，具有不必攜帶專用工具 的優點。另外，由於每個組合式插座都設有所述的保護蓋 -6- 200428709 發明說明,¾胃 3’、3”，所以不要求簡易工具部37的耐久性強，從而能夠 用合成樹脂構成，具有價格低廉的優點。另外，第十九圖 以及第二十圖所示的2個保護蓋3”，由於做成第二十一 圖以及第二十二圖所示的保護蓋3,的約一半大小，具有在 5 利用簡易工具部37將電線5壓入到壓接槽24a之際，能夠 使作用於保護盖的表面的力較小的優點。 「專利文獻1」 特開平5-13125號公報（第3頁、第一圖） 但是，在具備第十九圖以及第二十圖所示的2個保護 10蓋3”的組合式插座中，存在將2個保護蓋3”從接線盒2上 取下來後容易丟失的缺點。另外，第十九圖以及第二十圖 所示的保護蓋3”，存在按壓的表面面積小而不易按壓的問 題、和對4根電線5的施壓不平衡出現易引起前端不良而 導致接觸不良的問題。 另方面，在具備第二十一圖以及第二十二圖所示的 保護蓋3’的組合式插座中，由於用i個保護蓋3，就可以， 所以具有不易丟失保護蓋3,，以及用拇指按壓保護蓋3,時 有充足的工間等優點，但在接線作業時，由於必須將雙紐 電繞4的所用電線5同時壓人8個接線板24的壓接槽w 2〇中’與在使用第十九圖以及第二十圖所示的2個保護蓋3” 的場合所需要的力（約5kgf)相比將需要更大的力（碰紅 以上），需要用钳子等特殊的工具。鉗子不是一般攜帶的工 具，不能滿足施工人員希望減少攜帶的工具的需求。另外， 存在對8根電線5的施壓不平衡易引起前端不良導致接觸 -7- 200428709 發明說明#賣胃 不良的問題。 【發明内容】 本發明鑒於所述原因，其目的是提供一種無需壓擠工 5 具等專用工具或類似鉗子的工具就能夠進行接線作業而且 不易引起電線的前端不良的組合式插座。 第1項發明的組合式插座，其特徵在於，具備：開口 有插入組合式插頭的插頭插入口的外殼；排列在插頭插入 口中並可以與組合式插頭的接觸頭接觸的數根端子；豎立 10 設置有分別與各端子電連接的同時具有為連接絕緣包皮電 線的電線的壓接槽的數個接線板的接線盒；在接線盒上拆 裝自如並至少覆蓋接線盒中設置接線板的部位的保護蓋， 在保護蓋上突出設置簡易工具部，該簡易工具部在從接線 盒上取下保護蓋的狀態下，在從數個接線板中擇一選擇出 15 的一個接線板的壓接槽上壓入一根電線而使之電連接。採 用該結構，由於將從接線盒上取下來的保護蓋配置成簡易 工具部對應於一個接線板，利用簡易工具部將一根電線壓 入一個壓接槽，所以，與現有的那種將電線同時壓入所有 接線板或半數接線板中進行接線作業的情況相比，能夠使 20 作用於保護蓋的力減小，能夠不用壓擠工具等專用工具或 類似鉗子的工具進行接線作業，而且具有不易引起電線前 端部不良的效果。另外，由於也可以在從接線盒上摘下保 護蓋的狀態下，使用壓擠工具等專用工具進行接線作業， 就可以選擇接線作業的方法。 -8- 200428709 發明說明$賣Μ 第2項發明的組合式插座，其特徵在於，在第1項發 明中，所述保護蓋在安裝在所述接線盒的狀態下，在沒有 配置所述各電線的位置設置所述簡易工具部。採用該結 構，在接線作業結束後將保護蓋安裝到所述接線盒上時， 5 能夠防止所述簡易工具部碰到所述各電線。 第3項發明的組合式插座，其特徵在於，在第2項發 明中，所述接線盒，在與所述組合式插頭的插入方向正交 的方向的兩側部豎立設置所述接線板，所述簡易工具部被 收放在所述兩側部之間的部位内或該部位外的延長位置 10 的、沒有配置所述電線的一側位置上。採用該結構，能夠 防止所述簡易工具部碰到各接線板。 第4項發明的組合式插座，其特徵在於，在第2項發 明中，所述接線盒，在與所述組合式插頭的插入方向正交 的方向的兩側部豎立設置所述接線板，所述簡易工具部， 15 在安裝於所述接線盒上的狀態下配置在所述接線盒的外 側。採用該結構，能夠防止所述簡易工具部碰到各接線板。 第5項發明的組合式插座，其特徵在於，在第1至第 4項的發明中，所述簡易工具部，通過按壓所述保護蓋的 表面而將所述電線壓入所述壓接槽，所述保護蓋形成有在 20 按壓所述表面時放置手指的指肚的凹處。採用該結構，能 夠減輕在接線作業時按壓所述保護蓋的表面之際手指的負 擔。 第6項發明的組合式插座，其特徵在於，在第1至第 5項的發明中，所述保護蓋的、可以將各電線分別壓入壓 -9- 200428709 發明說明$賣胃 接槽的數個前端部分別突出設置在與各接線板相對應的位 置。採用該結構，與以往將電線同時壓入所有的接線板來 進行接線作業的場合相同，也可以使用鉗子那樣的普遍使 用的工具進行將電線同時壓入所有的接線板中的接線作 5 業，因此，增加了一種接線作業的方法的選擇。 第7項發明的組合式插座，其特徵在於，採用第6項 發明的結構，在所述接線盒上設置偶數對所述接線板，同 時在所述保護蓋上設置偶數對所述前端部，在所述保護蓋 上形成分離部，該分離部可以將所述保護蓋分割成所述前 10 端部的對數相等的兩個半個保護蓋。採用該結構，由於通 過分割所述保護蓋並按壓一邊的半個保護蓋的表面，將電 線同時壓入所有接線板的半數的接線板的壓接槽後，通過 按壓另一邊的半個保護蓋的表面，也可以進行將電線同時 壓入剩下的半數接線板的壓接槽中的接線作業，因此增加 15 了一種接線作業的方法的選擇。 【實施方式】 下面，參照第三圖以及第四圖對本實施方式的組合式 插座進行說明，與現有例相同的構成要素賦予同一符號來 20 進行說明。 本實施方式的組合式插座具備：插入組合式插頭的插 頭插入口 11a開口的外殼1 ;排列在插頭插入口 11a之中、 可以與組合式插頭的接觸頭接觸的數根（本實施方式中為 8根）線狀端子13 (參照第一圖）；豎立設置了分別與各端 -10- 200428709 發明說明®胃 子13電連接的同時連接絕緣包皮電線製的電線的多片（本 實施方式中為8片）接線板24 (參照第十三圖以及第十四 圖），並結合在外殼1上的接線盒2 ;在接線盒2上拆裝自 如、至少覆蓋接線盒2之中設有接線板24的部位的保護蓋 5 3 〇 外殼1，由具有絕緣性的合成樹脂製，具備長方體狀 的連接台11，所述插頭插入口 11a在連接台11的一面開 口。以下，以連接台11中插頭插入口 11a開口的一面為前 面，用第四圖中的上下方向來規定上下方向。從連接台11 10 的後面下部向後方連續一體突出設置與結合接線盒2的基 座12。 接線盒2配置在基座12的上面，各接線板24從接線 盒2的上面突出。這裏，8片接線板24在接線盒2的左右 兩側沿前後方向各配置4個。另外，各接線板24做成在上 15 部邊緣具有開口的壓接槽24a (參照第十三圖以及第十四 圖）的二齒叉狀，厚度方向配置成與接線盒2的左右方向 一致。另外，壓接槽24a的寬度設定為壓接槽24a的兩側 邊緣壓接到連接的電線5的芯線上的程度。因此，如果將 具有絕緣包皮的電線5從上方壓入壓接槽24a中，電線5 20 的絕緣包皮在壓接槽24a的兩側邊緣磨損，在壓接槽24a 中芯線壓接到接線板24。 並且，在接線盒2上面的左右兩側沿前後方向並列設 置突出於上面的尺寸比接線板24更大的數個保護壁23(參 照第五圖）。這裏，接線板24配置成使壓接槽24a在前後 -11- 200428709 發明說明$賣胃 與相鄰的保護壁23間相對應。另外，在前後方向相鄰的每 一對保護壁23的對向的面上沿上下方向形成保持接線板 24的保持槽23b (參照第一圖）。 另外，前後相鄰的每一對保護壁23之間的間隙尺寸設 5 定成能夠插入電線5。但是，每一對保護壁23間的間隙尺 寸與壓接槽24a的寬度尺寸相比要寬，而且，在每一對保 護壁23的上端形成傾斜的傾斜面以使上部間隙的尺寸擴 大，從而使雙紐電纜4的電線5易於導入每一對保護壁23 間的間隙。因此，將電線5從上方導入每一對保護壁23之 10 間的間隙，通過從上方將電線5壓入壓接槽24a，電線5 與接線板24的電連接也將變得容易進行。另外，在本實施 方式中，每一對保護壁23不僅具有作為保護接線板24的 保護部件的功能，還具有作為將電線5導入接線板24的壓 接槽24a的導向部件的功能。另外，位於前後方向正中間 15 的各保護壁23前後方向的寬度尺寸設定為與其它保護壁 23的前後方向寬度尺寸相比更大。 另外，如第五圖所示，在接線盒2的上面，在左右方 向的中間部位形成決定雙紐電纜4的鎧裝4a位置的定位凹 部22，在前後方向的最後面的左右保護壁23的相互對向 20 的面上分別設有將雙紐電纜4保持在與定位凹部22之間的 保持突起26。另外，保持突起26間的尺寸設定成略小於4 對8芯的雙紐電纜4的鎧裝4a的外徑。 因此，如果將4對8芯的雙紐電纜4的鎧裝4a從接線 盒2的上方導入定位凹部22,鎧裝4的局部被保持突起26 -12- 428709 發明說明,_胃 壓得凹進去，就能夠將雙紐電纜4挾持在定位凹部22的内 底面和一對保持突起26之間並保持，如果將雙紐電纜4的 各電線5壓入接線板24的壓接槽2如，電線5就和接線板 24電連接。 5 另外，在接線盒2前後方向正中間的各保護壁23的外 側面突出設有用於連結保護蓋3的連結爪27，使得保護蓋 3可以拆裝地連結。另外，在連結爪27 (參照第五圖）的 上部形成傾斜的導引面27a(參照第五圖）以使從接近上端 邊緣時從外側面的突出量減小。 10 另一方面，保護蓋3是合成樹脂的成形品，如第六圖 至第九圖所示，從所形成的覆蓋住接線盒2上面那麼大尺 寸的蓋體31左右兩側的下端邊緣，設有跨越數個導向壁 23的外側面而配置的側片32。在這裏，在側片32的前後 方向的中間部位形成與連結爪27進行凹凸配合的矩形連 15 結孔32a。另外，各側片32在前後方向在連結孔32a的兩 側形成下邊開口的切口槽32b，同時在前後方向在比切口 槽32b距離連結孔32a更遠的部位形成上邊開口的切口槽 32c，在側片32中相鄰的切口槽32b、32c間的部位容易向 前後方向彎曲。重要的是，側片32在前後方向在相鄰的一 20 對切口槽32b間的部位形成連結孔32a，切口槽32b之間的 部位構成用於與接線盒2進行連結的連結片32d。 另外，在各側片32中從前後兩側的切口槽32c之間的 部位的上端邊緣向上方延伸來設置解除片33,在蓋體31 的左右兩側面對應於解除片33的部位形成缺口部31 a。 -13- 200428709 發明說明®Μ 然後，在將保護蓋3安裝到接線盒2之際，通過使保 護蓋3從接線盒2的上方接近接線盒2，連結片32d沿導 引面27a彎曲，最後通過連結爪27與設在連結片32d上的 連結孔32a進行凹凸配合，保護蓋3就與接線盒2連結。 5 另一方面，在從接線盒2上取下保護蓋3之際，由於使解 除片33的上端部之間接近就能夠解除連結爪27和連結孔 32a的凹凸配合，所以能夠很容易地從接線盒2上取下保護 蓋3。 然而，由於所述電線5容易彎曲而難以用手壓入到接 10 線板24的壓接槽24a中，所以，為了使電線5很容易地壓 入到接線板24的壓接槽24a中，在本實施方式中，在將保 護蓋3從接線盒2取下來的狀態，在保護蓋3上設置簡易 工具部35將一根電線5壓入從數個接線板24選擇的一個 接線板24的壓接槽24a中來使之電連接。在這裏，簡易工 15 具部35做成具有向下邊開口的插入槽35a的二齒叉狀，在 寬度方向的兩側邊緣與其他部位相比形成更厚的加強部 35b。另外，加強部35b之間的尺寸設定為與左右方向的保 護壁23的寬度大致相同的尺寸，加強部35b沿前後方向的 尺寸設定為比前後方向相鄰的一對保護壁23間的尺寸還 20 略寬。 然後，如第一圖所示，在將電線5在前後方向導入相 鄰的一對保護壁23之間的間隙的狀態，將保護蓋3的簡易 工具部35配置成在一對保護壁23間的間隙與接線板24交 叉的形式（此時，保護壁23被左右一對加強部35b挾住）， -14- 200428709 發明說明$賣胃 如第二圖所示，如果把手指（例如大拇指）6的指肚放在 蓋主體31的上面（即保護蓋3的表面）並朝下方按壓，電 線5被簡易工具部35按壓而使得電線5被壓入接線板24 的壓接槽24a中。通過對每個接線板24分別進行這種操 5 作，就能夠將電線5壓入到所有的接線板24中。 如上所述，在通過對保護蓋3的蓋主體31的表面進行 按壓而將電線壓入各接線板24的壓接槽24a之際，由於各 接線板24被導入形成於簡易工具部35的插入槽35a内， 所以，電線5在接線板24的厚度方向兩側被簡易工具部 10 35按壓，在接線板24的厚度方向兩側電線5不彎曲就能 夠壓入壓接槽24a中。 總之，在本實施方式的組合式插座中，由於在在保護 蓋3上設置簡易工具部25來在將保護蓋3從接線盒2取下 來的狀態將電線5壓入從數個接線板24中選擇的一個接線 15 板24的壓接槽24a以使之電連接，所以，能夠將從接線盒 2上取下來的保護蓋3配置成簡易工具部35對應於一個接 線板24並利用簡易工具部35將一根電線5壓入一個壓接 槽24a中，與以往那種將電線5同時壓入所有接線板24或 者一半接線板24來進行接線作業的場合相比，能夠使作用 20 於保護蓋3的力減小，不使用壓擠工具7 (參照第十六圖） 等專用工具或者鉗子似的工具就能夠進行接線作業，而且 不易引起電線5的前端不良。在這裏，簡易工具部35通過 保護蓋3的表面被按壓而將電線5壓入壓接槽24a内，由 於保護蓋3在按壓表面之際在蓋主體表面31的表面形成放 -15- 200428709 發明說明 置手指6指肚的凹處31b，在接線作業時能夠減輕按壓保 護蓋3的表面之際手指6的負擔。 這襄，由於保護蓋3在將保護蓋3安裝在接線盒2上 的狀態，在沒有配置各電線5的突出位置設置簡易工具部 5 35，所以在接線作業結束後將保護蓋3安裝到接線盒2上 時，能夠防止簡易工具部35碰到各電線5。即，本實施方 式的接線盒2,如第十圖所示，在與保護蓋3的對向面（上 面），在與組合式插頭的插入方向正交方向的兩側部（也就 是左右兩側部）各豎著設有4片接線板24，由於簡易工具 10 部35如第十圖中虛線所示的那樣，設置在收放在所述兩側 之間的部位内沒有配置電線5的一側的位置（在前後方向 與決定雙紐電纜4的鎧裝4a位置的定位凹部22反對側的 位置），所以，具有能夠防止簡易工具部35碰到各接線板 24以及各電線5的優點。另外，在本實施方式中，由於將 15 簡易工具部35設在保護蓋3的中心轴上而使保護蓋3的整 體形狀成為左右對稱的形狀，所以，具有在按壓保護蓋3 的表面之際容易按壓保護蓋3的優點，而且，在保護蓋3 安裝在接線盒2上的狀態，具有能夠有效利用保護蓋3下 的空餘空間的優點。另外，簡易工具部35既可以如第十圖 20 中用雙點劃線所示的那樣設置在容納於所述兩側部之間的 部位内的位置，也可以如第十圖中用單點劃線所示的那 樣，設置在收放於所述兩側部之間的部位外的外延出來的 位置（也就是所述兩側部之間的部位的延長線上的位置） 沒有配置電線5的一側的位置，不論那種情況都具有同樣 -16- 200428709 發明說明_胃 的優點。另外，簡易工具部35，可以如第十一圖中用雙點 劃線所示的那樣，在從接線盒2上取下保護蓋的狀態設置 像配置在接線盒2的外側那樣的4個處所的任何一個，能 夠防止簡易工具部35碰到各接線板24。 5 而且，在從接線盒2上取下保護蓋的狀態，也可以利 用市場上出售的壓擠工具7將電線5連接到接線板24上。 重要的是，採用本實施方式的結構，能夠根據需要選擇接 線作業的方法。 另外，保護蓋3在蓋主體31的上壁的裏面設有格子狀 10 的加強肋34 (參照第九圖），在由蓋主體31覆蓋接線盒2 時使被導入相鄰的一對保護壁23之間的間隙的電線5可以 壓入到壓入縫隙24a的8個前端部37從加強肋34的下端 邊緣突出來。即保護蓋3在蓋主體31的下面分別設有突出 於左右的4個前端部37，由於各前端部37分別設置在對 15 應於各接線板24的位置，所以也可以將電線5同時壓入左 右各4個接線板24(也就是8個接線板24)的壓接槽24a， 與現有那種將電線5同時壓入所有的接線板24中進行接線 作業的場合相同，由於也可使用钳子之類普遍使用的工具 進行將電線5同時壓入到所有接線板24中的接線作業，所 20 以接線作業的方法將有更多的選擇。 另外，在前端部37形成有插入接線板24的上端部的 插入溝37a。因此，在電線5在被壓入到壓接槽24a的狀態， 通過保護蓋37按壓電線5,就能夠防止電線5沿壓接槽24a 拔脫，而且，通過保護蓋3覆蓋住接線板24就使接線板 -17- 發明說明#賣Μ 24得到保護。 在本實施方式的組合式插座中，在接線盒2上設有偶 數對（4對）接線板8，同時在保護蓋3上設有偶數對（4 對）前端部37，但是，如第十二圖所示，如果在保護蓋3 5 上做成可以將保護蓋3分割成前端部37的對數均等的兩個 半個保護蓋的分離部39，沿分離部39分割保護蓋3並且 通過按壓一邊的半個保護蓋的表面，將電線5同時壓入所 有的接線板24的半數接線板24的壓接槽後，通過按壓另 一邊的半個保護蓋的表面，由於也能夠進行將電線5同時 10 壓入到剩下的半數接線板24的壓接槽24a中的接線作業， 所以，接線作業的方法將增加一種選擇。 「發明效果」 第1項發明，具備：插入組合式插頭的插頭插入口開 15 口的外殼；排列在插頭插入口中、可以與組合式插頭的接 觸頭接觸的數根端子；分別豎立設置有與數個端子電連接 的同時具有與絕緣包皮電線製的電線連接的壓接槽的數個 接線板的接線盒；在接線盒上拆裝自如並覆蓋接線盒中至 少設有接線板部位的保護蓋，在從接線盒上摘下保護蓋的 20 狀態下，在保護蓋上設置將一根電線壓入從數個接線板中 選擇的一個接線板的壓接槽使之電連接的簡易工具部。由 於將從接線盒上取下來的保護蓋配置成簡易工具部對應於 一個接線板，利用簡易工具部將一根電線壓入一個壓接 槽，所以，與現有的那種將電線同時壓入所有接線板或半 200428709 數接線板中進行接線作業的情況相比，能夠使作用於保護 蓋的力減小，能夠不用壓擠工具等專用工具或類似鉗子的 工具進行接線作業，而且具有不易引起電線前端部不良的 效果。另外，由於也可以在從接線盒上摘下保護蓋的狀態 5 下，使用壓擠工具等專用工具進行接線作業，就可以選擇 接線作業的方法。 第2項發明，在第1項發明中，由於所述保護蓋在安 裝在所述接線盒的狀態下，在沒有配置所述各電線的位置 設置所述簡易工具部，所以在接線作業結束後將保護蓋安 10 裝到所述接線盒上時，具有能夠防止所述簡易工具部碰到 所述各電線的效果。 第3項發明，在第2項發明中，所述接線盒在與所述 組合式插頭的插入方向正交的方向的兩側豎立設置所述接 線板，由於簡易工具部被收放在所述兩側間的部位或該部 15 位外的延長位置沒有配置所述電線的一側位置，所以具有 能夠防止所述簡易工具部碰到各接線板的效果。 第4項發明，在第2項發明中，所述接線盒在與所述 組合式插頭的插入方向正交的方向的兩側豎立設置所述接 線板，由於所述簡易工具部在安裝在所述接線盒上的狀態 20 下配置在所述接線盒的外側，所以具有能夠防止所述簡易 工具部碰到各接線板的效果。

technical Zen T, the prior art, the content, the embodiment, and the diagrams of the invention) [Technical field to which the invention belongs] The present invention relates to a wiring provided with a crimping groove Board, a combination socket that presses the wires of the insulated sheathed wire into the crimping grooves of the terminal board to connect. 5 [Prior art] Hitherto, as a cable for information communication, a double-button cable that houses and retracts several pairs of double-button cables has been widely used, and a combination socket having a junction box for connecting the double-button cables has been widely used. As such a terminal box, a terminal box provided with a terminal board having a crimping groove is known. The terminal board is formed into a two-forked fork shape with a crimping groove with 10 openings on one periphery. If the wires constituting the double button cable are crimped into the crimping groove, the insulation sheath of the wire is cut off around the crimping groove ' The core wire is crimped around the crimping groove. That is, as shown in FIGS. 13 and 14, the terminal box 2 is provided with a plurality of protective walls 23 protruding from the terminal board 24 to protect the terminal board 24, so that the crimping grooves are formed. 24a 15 corresponds to the adjacent protective wall 23 to configure the wiring board 24. As shown in FIG. 15, the wires 5 of the double-button cable 4 are introduced between the adjacent protective walls 23, and the wires 5 are pressed in. In the crimping groove 24a of the terminal board 24. The width of the crimping groove 24a is set to be smaller than the diameter of the core wire of the electric wire 5. Here, since a relatively large force is required to press the electric wire 5 into the crimping groove 20a to 24a, a special tool such as the crimping tool 7 shown in Fig. 16 is generally used to press the electric wire 5 into the crimping groove 24a. By using such a squeezing tool 7, it is possible to simultaneously press in the electric wire 5 and cut off the remaining electric wires, and there is an advantage that the wiring work is easy. However, there is a high price for a special tool such as the pressing tool 7 (continued when the description page is insufficient, please note and use the continued page) -5- 200428709 Invention Note® Stomach problem, provide this The simple tool 8 as shown in FIG. 17 includes a bifurcated fork-shaped tip portion 8 a having a pair of teeth with a groove. Here, when the simple tool 8 shown in Fig. 17 is used for wiring work, the front end portion 8a is used to press the electric wire 5 into the crimping groove 24a, and then the remaining electric wire 5 can be cut with a cutter or the like. Although the simple tool 8 shown in FIG. 17 is cheaper than the synthetic resin pressing tool 7, it has a problem that the durability of a plurality of modular sockets is low. For durability, the front end portion 8a must be made of a metal product, which is more expensive than a simple tool. In addition, in the wiring operation of the wiring board 24 and the electric wire 5, when special tools such as the pressing tool 7 shown in FIG. 16 or the simple tool 8 shown in FIG. 17 are used, these special tools must always be carried . Here, as shown in FIG. 18, for each junction box 2 15 capable of arranging four pairs of 8-core twisted cables 4 between adjacent protective walls 23 (that is, in the junction box 2 are provided with 8 wiring boards 24), which provides the following technical solutions: In order to cover the two pairs of wiring boards 24 respectively, two protective covers 3 "shown in Figure 19 and Figure 20 are installed, each Two pairs of simple tool parts 37 (for example, refer to Patent Document 1) for crimping the electric wires 5 into the crimping groove 24a are provided, or to cover four pairs of wiring boards 24, 20 is installed in the twenty-first figure and the twentieth The protective cover 3 'shown in the second figure is provided with four pairs of simple tool parts 37 for crimping the electric wires 5 into the crimping groove 24a. By using the protective covers 3' and 3 "described above, several electric wires 5 can be They are collectively connected to the terminal board 24 and have the advantage of not having to carry special tools. In addition, since each of the combined sockets is provided with the above-mentioned protective cover-6-200428709 Invention Description, ¾ stomach 3 ', 3 ", the durability of the simple tool portion 37 is not required to be strong, so that it can be made of synthetic resin. It has the advantage of low price. In addition, the two protective covers 3 "shown in Figs. 19 and 20 are made about the protective cover 3 shown in Figs. 21 and 22. The half size has the advantage that the force applied to the surface of the protective cover can be made smaller when the electric wire 5 is pressed into the crimping groove 24 a by the simple tool portion 37. "Patent Document 1" Japanese Patent Application Laid-Open No. 5-13125 (page 3, first picture) However, in a combination socket having two protective 10 covers 3 "shown in the nineteenth and twentieth pictures, There is a disadvantage that two protective covers 3 "are easily lost after being removed from the junction box 2. In addition, the protective cover 3 "shown in the nineteenth and twentieth figures has the problem that the pressing surface area is small and it is not easy to press, and the imbalance of the pressing force on the four wires 5 is likely to cause the front end to be defective and cause contact. On the other hand, in the combination socket provided with the protective cover 3 'shown in Figs. 21 and 22, since i protective covers 3 can be used, it is difficult to lose the protective cover. 3, and there is sufficient work space when the protective cover 3 is pressed with the thumb, but when wiring work, because the used wire 5 of the double button winding 4 must be pressed to the crimping grooves of the 8 terminal boards 24 at the same time w 20 ′ will require more force (approximately 5kgf) than the force (approximately 5 kgf) required when using the two protective covers 3 ”shown in Figure 19 and Figure 20. Special tools such as pliers are required. Pliers are not a commonly carried tool and cannot meet the needs of construction workers who want to reduce the number of tools they carry. In addition, there is a problem that the imbalance of pressure applied to the eight wires 5 may cause a poor front end and cause contact. -7- 200428709 Invention Description #Selling stomach is not good. [Summary of the Invention] The present invention has been made in view of the above-mentioned reasons, and an object thereof is to provide a combined socket that can perform wiring work without the need for a special tool such as a squeezing tool or a tool like pliers, and does not easily cause a bad front end of a wire. The modular socket of the first invention is characterized by comprising: a housing having a plug insertion opening into which the modular plug is inserted; a plurality of terminals arranged in the plug insertion opening and capable of contacting the contacts of the modular plug; and erected 10 Junction box provided with several terminal boards which are electrically connected to each terminal and have crimping grooves for connecting the wires of the insulated sheathed wire; the terminal box is freely removable and covers at least the part where the terminal board is provided in the terminal box A protective cover is provided with a simple tool part protruding from the protective cover. When the protective cover is removed from the terminal box, one of the terminal board crimping grooves is selected from 15 of the several terminal boards. Push in a wire to make an electrical connection. With this structure, since the protective cover removed from the junction box is arranged so that the simple tool part corresponds to a terminal board, and a wire is pressed into a crimping groove by the simple tool part, the wire Compared to the case where all the terminal boards or half of the terminal boards are pressed at the same time for wiring work, the force on the protective cover can be reduced by 20, and the wiring work can be performed without using special tools such as pressing tools or pliers-like tools. It is not easy to cause a bad effect at the tip of the wire. In addition, since the protective cover can be removed from the terminal box and the wiring work can be performed using a special tool such as a squeeze tool, the wiring method can be selected. -8- 200428709 Description of the invention The combination socket of the second invention is characterized in that, in the first invention, the protective cover is installed in the junction box without disposing the various components. The position of the electric wire is provided with the simple tool section. With this structure, when the protective cover is attached to the junction box after the wiring operation is completed, the simple tool section can be prevented from hitting the electric wires. A modular socket according to a third invention is characterized in that, in the second invention, the terminal box is provided with the terminal board on both sides in a direction orthogonal to the insertion direction of the modular plug, The simple tool part is housed in a position between the two side parts or an extended position 10 outside the part on the side where the electric wire is not arranged.

A modular jack according to a fourth invention is characterized in that, in the second invention, the terminal box is provided with the terminal board on both sides in a direction orthogonal to the insertion direction of the modular plug, The simple tool part 15 is arranged outside the terminal box in a state of being mounted on the terminal box. With this structure, the simple tool portion can be prevented from hitting each wiring board. According to a fifth aspect of the invention, in the combined socket of the first to fourth aspects, the simple tool section presses the electric wire into the crimping groove by pressing a surface of the protective cover. The protective cover is formed with a recess in which a fingertip of a finger is placed when the surface is pressed. With this structure, the burden on the fingers when the surface of the protective cover is pressed during the wiring operation can be reduced. The combined socket of the sixth invention is characterized in that, in the inventions of the first to fifth inventions, the protective cover, which can press each electric wire separately, is -9-200428709 Invention Description A plurality of front end portions are respectively provided at positions corresponding to the respective wiring boards. With this structure, as in the conventional case where the wires are simultaneously pressed into all the wiring boards to perform the wiring operation, the commonly used tools such as pliers can also be used to perform the wiring of the wires into the wiring boards simultaneously. Therefore, a choice of a method of wiring work is added. A combined socket according to a seventh invention is characterized in that, using the structure of the sixth invention, an even number of pairs of the terminal boards are provided on the terminal box, and an even number of the front ends are provided on the protective cover, A separation portion is formed on the protection cover, and the separation portion can divide the protection cover into two and a half protective covers with the same number of pairs of the first 10 end portions. With this structure, since the protective cover is divided and the surface of one half of the protective cover is pressed, the wires are simultaneously pressed into the crimping grooves of half of the terminal boards of all the terminal boards, and then the other half of the protective cover is pressed. The surface can also be used to press the wires into the crimping grooves of the remaining half of the terminal boards at the same time. Therefore, a choice of 15 methods of wiring operations is added. [Embodiment] Hereinafter, a modular jack according to the present embodiment will be described with reference to the third and fourth figures, and the same components as those in the conventional example are assigned the same reference numerals and described. The modular jack of the present embodiment includes a housing 1 having an opening for the plug insertion port 11a of the modular plug, and a plurality of the rows arranged in the plug insertion port 11a so as to be in contact with the contacts of the modular plug (in this embodiment, 8) Wire-shaped terminals 13 (refer to the first figure); a plurality of pieces (in this embodiment) which are electrically connected to each end -10- 200428709 Description of the Invention® Weizi 13 and are connected to the insulated wire 8 pieces) terminal board 24 (refer to the thirteenth and fourteenth figures), and the junction box 2 combined with the housing 1; the junction box 2 is freely disassembled and at least covers the junction box 2 with wiring The protective cover 5 3 of the plate 24 is made of an insulating synthetic resin and has a rectangular parallelepiped connection base 11. The plug insertion opening 11 a is opened on one side of the connection base 11. Hereinafter, the open side of the plug insertion port 11a in the connection base 11 is used as the front surface, and the vertical direction is defined by the vertical direction in the fourth figure. A base 12 is provided continuously and integrally from the rear lower part of the connection base 11 10 to the rear and integrally with the junction box 2. The terminal box 2 is disposed on the upper surface of the base 12, and each terminal plate 24 projects from the upper surface of the terminal box 2. Here, eight terminal boards 24 are arranged on each of the left and right sides of the junction box 2 in the front-rear direction. In addition, each terminal board 24 is formed into a bifurcated fork-shaped groove having a crimping groove 24a (refer to Figs. 13 and 14) with openings at the upper 15 edges, and the thickness direction is arranged to coincide with the left-right direction of the terminal box 2. . The width of the crimping groove 24a is set to such an extent that the edges of both sides of the crimping groove 24a are crimped to the core wire of the connected electric wire 5. Therefore, if the electric wire 5 with an insulating covering is crimped into the crimping groove 24a from above, the insulating covering of the electric wire 5 20 is worn on both edges of the crimping groove 24a, and the core wire is crimped to the terminal board 24 in the crimping groove 24a. . In addition, on the left and right sides of the upper surface of the junction box 2, a plurality of protective walls 23 having a larger size than the junction plate 24 are juxtaposed in the front-rear direction (see the fifth figure). Here, the terminal board 24 is arranged so that the crimping groove 24a is located at the front and rear. In addition, a holding groove 23b (see the first figure) for holding the wiring board 24 is formed in the up-down direction on the facing surfaces of each pair of the protective walls 23 adjacent in the front-back direction. In addition, the size of the gap between each pair of protective walls 23 adjacent to each other is set so that the electric wires 5 can be inserted. However, the size of the gap between each pair of protective walls 23 is wider than the width of the crimping groove 24a, and an inclined inclined surface is formed at the upper ends of each pair of protective walls 23 to enlarge the size of the upper gap, thereby The wires 5 of the double twisted cable 4 are easily led into the gap between each pair of protective walls 23. Therefore, by inserting the electric wires 5 into the gap between each pair of the protective walls 23 from above, and by pressing the electric wires 5 into the crimping grooves 24a from above, the electric connection between the electric wires 5 and the terminal board 24 becomes easy. In addition, in this embodiment, each pair of protective walls 23 not only functions as a protective member for protecting the wiring board 24, but also functions as a guide member for introducing the electric wire 5 into the crimping groove 24a of the wiring board 24. In addition, the width dimension in the front-rear direction of each protective wall 23 located in the middle 15 in the front-back direction is set to be larger than the width dimension in the front-rear direction of the other protective walls 23. In addition, as shown in the fifth figure, a positioning recess 22 is formed on the upper surface of the junction box 2 at the middle portion in the left-right direction, which determines the position of the armor 4a of the double-button cable 4, and the left and right protective walls 23 on the rear surface in the front-rear direction. The surfaces 20 facing each other are respectively provided with holding protrusions 26 that hold the double button cable 4 between the positioning cables 22 and the positioning recess 22. In addition, the dimensions between the holding protrusions 26 are set to be slightly smaller than the outer diameter of the armor 4a of the four-pair, eight-core, double-stranded cable 4. Therefore, if the armor 4a of 4 pairs of 8-core double button cables 4 is introduced into the positioning recess 22 from above the junction box 2, a part of the armor 4 is held by the protrusion 26 -12- 428709 Description of the invention, the stomach pressure is recessed Then, the double button cable 4 can be held between the inner bottom surface of the positioning recess 22 and a pair of holding protrusions 26 and held. If the wires 5 of the double button cable 4 are pressed into the crimping groove 2 of the terminal board 24, for example, wires 5 is electrically connected to the wiring board 24. 5 In addition, a connecting claw 27 for connecting the protective cover 3 is protruded on the outer side surface of each protective wall 23 in the middle in the front-rear direction of the junction box 2, so that the protective cover 3 can be detachably connected. In addition, an inclined guide surface 27a (refer to the fifth figure) is formed on the upper portion of the coupling claw 27 (refer to the fifth figure) so that the amount of protrusion from the outer side surface when approaching the upper edge is reduced. 10 On the other hand, the protective cover 3 is a molded product of synthetic resin. As shown in FIGS. 6 to 9, from the lower end edges of the left and right sides of the cover body 31 covering the large size of the junction box 2, A side piece 32 is provided so as to span the outer side surfaces of the plurality of guide walls 23. Here, a rectangular coupling hole 32a is formed in the middle portion in the front-rear direction of the side piece 32 to engage the coupling claw 27 in a concave-convex manner. In addition, each side piece 32 forms a notch groove 32b opened at the lower side on both sides of the connection hole 32a in the front-rear direction, and at the same time forms a notch groove 32c opened at the upper side in the front-rear direction at a position farther from the connection hole 32a than the notch groove 32b. The portion between the adjacent notch grooves 32b and 32c in the side sheet 32 is easily bent in the forward and backward directions. It is important that the side pieces 32 form connection holes 32a in the portion between the adjacent pair of 20 notch grooves 32b in the front-rear direction, and the portions between the notch grooves 32b constitute the connection piece 32d for connection with the junction box 2. In addition, in each side piece 32, release pieces 33 are extended upward from the upper edge of the portion between the notch grooves 32c on the front and back sides, and cutout portions are formed on the left and right side surfaces of the cover body 31 corresponding to the release piece 33. 31 a. -13- 200428709 Description of the invention ®M Then, when attaching the protective cover 3 to the terminal box 2, the protective cover 3 approaches the terminal box 2 from above the terminal box 2, the connecting piece 32d is bent along the guide surface 27a, and finally The connection claw 27 is mated with the connection hole 32a provided in the connection piece 32d, so that the protective cover 3 is connected to the junction box 2. 5 On the other hand, when the protective cover 3 is removed from the junction box 2, since the upper and lower ends of the release piece 33 are brought close to each other, the concave-convex engagement of the connection claw 27 and the connection hole 32a can be released, so it can be easily removed Remove the protective cover 3 from the junction box 2. However, since the electric wires 5 are easy to bend and difficult to press into the crimping grooves 24 a of the 10-wire board 24 by hand, in order to easily press the electric wires 5 into the crimping grooves 24 a of the terminal board 24, In the present embodiment, in a state where the protective cover 3 is removed from the terminal box 2, a simple tool portion 35 is provided on the protective cover 3 to press a wire 5 into one of the terminal boards 24 selected from a plurality of terminal boards 24. The crimping groove 24a is electrically connected. Here, the simple tool part 35 is formed into a bifurcated fork-like shape having an insertion groove 35a opened downward, and both side edges in the width direction are formed with thicker reinforcing parts 35b than other parts. The size between the reinforcing portions 35b is set to be approximately the same as the width of the protective wall 23 in the left-right direction, and the size of the reinforcing portion 35b in the front-to-back direction is set to be larger than the size between a pair of protective walls 23 adjacent to the front-to-back direction. 20 Slightly wider. Then, as shown in the first figure, the simple tool portion 35 of the protective cover 3 is arranged between the pair of protective walls 23 in a state where the electric wire 5 is introduced into the gap between the adjacent pair of protective walls 23 in the front-rear direction. The form in which the gap intersects with the wiring board 24 (at this time, the protective wall 23 is held by the pair of left and right reinforcing portions 35b), -14-200428709 Description of the invention As shown in the second figure, if you put your finger (such as a thumb ) 6 is placed on the cover main body 31 (ie, the surface of the protective cover 3) and pressed downward, and the electric wire 5 is pressed by the simple tool part 35 so that the electric wire 5 is pressed into the crimping groove 24 a of the wiring board 24. By performing this operation separately for each wiring board 24, the electric wires 5 can be pressed into all the wiring boards 24. As described above, when the electric wire is pressed into the crimping groove 24 a of each terminal board 24 by pressing the surface of the cover main body 31 of the protective cover 3, each terminal board 24 is introduced into the insertion formed in the simple tool portion 35. In the groove 35a, the electric wire 5 is pressed by the simple tool part 1035 on both sides in the thickness direction of the terminal plate 24, and the electric wires 5 can be pressed into the crimping groove 24a without being bent on both sides in the thickness direction of the terminal plate 24. In short, in the modular socket of the present embodiment, since the simple tool part 25 is provided on the protective cover 3, the electric wire 5 is pressed into the several terminal boards 24 while the protective cover 3 is removed from the terminal box 2. The selected crimping groove 24a of the terminal 15 board 24 is selected for electrical connection. Therefore, the protective cover 3 removed from the terminal box 2 can be arranged as a simple tool section 35 corresponding to one terminal board 24 and the simple tool section can be used. 35 Pressing a wire 5 into a crimping groove 24a can make the action 20 on the protective cover compared to the conventional case where the wire 5 is simultaneously pressed into all or 24 of the terminal boards 24 for wiring operation. The force of 3 is reduced, the wiring work can be performed without using a special tool such as the pressing tool 7 (refer to FIG. 16) or a pliers-like tool, and the tip of the wire 5 is not easily caused. Here, the simple tool part 35 presses the electric wire 5 into the crimping groove 24a by pressing the surface of the protective cover 3. Since the protective cover 3 is formed on the surface of the cover main body surface 31 when the surface is pressed, it is -15-200428709 Invention It will be explained that the recess 31 b of the finger belly of the finger 6 can reduce the burden on the finger 6 when the surface of the protective cover 3 is pressed during the wiring operation. In this case, since the protective cover 3 is in a state where the protective cover 3 is mounted on the junction box 2 and the simple tool part 5 35 is provided at a protruding position where each electric wire 5 is not arranged, the protective cover 3 is attached to the wiring after the wiring work is completed. When the box 2 is mounted, the simple tool section 35 can be prevented from hitting each of the electric wires 5. That is, as shown in the tenth figure, the junction box 2 of the present embodiment is opposite to the protective cover 3 (upper surface) on both sides (that is, the left and right sides) in a direction orthogonal to the insertion direction of the modular plug. (Side) Each of the four wiring boards 24 is provided vertically. Since the simple tool 10, 35, as shown by the dashed line in the tenth figure, is provided in the place where the wires 5 are not arranged, The position on one side (the position on the opposite side to the positioning recess 22 that determines the position of the sheath 4a of the double-button cable 4 in the front-rear direction) has the advantage that the simple tool portion 35 can be prevented from hitting each of the terminal boards 24 and each of the wires 5 . In addition, in the present embodiment, since 15 simple tool portions 35 are provided on the central axis of the protective cover 3, the entire shape of the protective cover 3 becomes a left-right symmetrical shape. Therefore, when the surface of the protective cover 3 is pressed, The protective cover 3 is easy to press, and in a state where the protective cover 3 is mounted on the junction box 2, there is an advantage that the free space under the protective cover 3 can be effectively used. In addition, the simple tool portion 35 may be provided in a position accommodated between the two side portions as shown by a two-dot chain line in FIG. As indicated by the dashed line, it is provided at an extended position (that is, a position on the extension line of the portion between the two side portions) that is placed outside the portion that is stored between the two side portions. The position of one side has the same advantage regardless of the situation. In addition, the simple tool section 35 can be provided in four places like the outside of the terminal box 2 in a state where the protective cover is removed from the terminal box 2 as shown by a two-dot chain line in the eleventh figure. Either of these can prevent the simple tool section 35 from hitting each of the terminal boards 24. 5 Also, in a state where the protective cover is removed from the junction box 2, the electric wire 5 may be connected to the junction board 24 by using a commercially available pressing tool 7. It is important to adopt the structure of this embodiment that the method of connection work can be selected as required. In addition, the protective cover 3 is provided with reinforcing ribs 34 (see the ninth figure) having a lattice shape 10 on the inner surface of the upper wall of the cover main body 31. When the terminal block 2 is covered by the cover main body 31, a pair of adjacent protective walls are introduced. The electric wires 5 with a gap of 23 can be pressed into the eight front end portions 37 of the press-fitting slit 24 a to protrude from the lower end edge of the reinforcing rib 34. That is, the protective cover 3 is provided with four front end portions 37 protruding from the left and right under the cover main body 31. Since each front end portion 37 is provided at a position corresponding to 15 corresponding to each wiring board 24, the wire 5 can also be pressed at the same time. The crimping grooves 24a of the four terminal boards 24 (that is, eight terminal boards 24) on the left and right sides are the same as the conventional case where the wires 5 are pressed into all the terminal boards 24 at the same time to perform wiring operations. Tools such as pliers are commonly used to perform the wiring operation of simultaneously pressing the electric wires 5 into all the wiring boards 24, so there will be more options for the wiring operation method. In addition, an insertion groove 37a is formed in the front end portion 37 to insert the upper end portion of the terminal plate 24. Therefore, in a state where the electric wire 5 is press-fitted into the crimping groove 24a, pressing the electric wire 5 by the protective cover 37 can prevent the electric wire 5 from being pulled out along the crimping groove 24a, and the protective cover 3 covers the wiring board 24. The terminal board -17- invention description # 卖 Μ 24 is protected. In the modular socket of this embodiment, an even-numbered pair (4 pairs) of terminal boards 8 are provided on the junction box 2 and an even-numbered pair (4 pairs) of front ends 37 are provided on the protective cover 3, but as in the tenth As shown in the two figures, if the protective cover 3 5 is formed as a separating portion 39 that can divide the protective cover 3 into two equal half halves of the front end portion 37, divide the protective cover 3 along the separating portion 39 and press On the surface of the half protective cover on one side, the wires 5 are simultaneously pressed into the crimping grooves of half of the terminal plates 24 of all the terminal plates 24, and by pressing the surface of the half protective cover on the other side, the wires 5 can also be carried out. At the same time, 10 wiring operations are crimped into the crimping grooves 24a of the remaining half of the wiring board 24, so the wiring operation method will add an option. "Inventive effect" The first invention includes: a housing having a 15-port plug insertion opening for inserting the modular plug; a plurality of terminals arranged in the plug insertion opening and capable of contacting the contact points of the modular plug; Several terminals are electrically connected, and the terminal box is provided with several terminal boards with crimping grooves connected to the wires made of insulated and covered wires. The terminal box is detachably mounted and covers at least the terminal board in the terminal box. In the 20 state with the protective cover removed from the terminal box, a simple tool section is provided on the protective cover to press a wire into a crimping groove of one of the terminal boards selected from several terminal boards for electrical connection. Since the protective cover removed from the terminal box is arranged so that the simple tool part corresponds to one terminal board, and a wire is pressed into a crimping groove by the simple tool part, the wires are simultaneously pressed into all of the existing ones. Compared with the wiring operation in the terminal board or half 200428709 terminal board, the force acting on the protective cover can be reduced, the wiring operation can be performed without using special tools such as pressing tools or pliers-like tools, and it is not easy to cause wires Bad effect at the tip. In addition, since the protective cover can also be removed from the terminal box 5, you can use a special tool such as a squeezing tool to perform the wiring operation, so you can choose the wiring method. According to the second invention, in the first invention, since the protective cover is installed in the junction box, the simple tool section is provided at a position where the electric wires are not arranged, so after the wiring work is completed When the protective cover 10 is attached to the junction box, there is an effect that the simple tool part can be prevented from hitting the electric wires. According to a third invention, in the second invention, the terminal box is provided with the terminal board erected on both sides in a direction orthogonal to the insertion direction of the modular plug, and the simple tool portion is stored in the terminal box. The position between the two sides or the extended position beyond the 15th position of the part is not provided with the one side position of the electric wire, so that the simple tool part can be prevented from hitting each wiring board. According to a fourth invention, in the second invention, the terminal box is provided with the terminal board on both sides in a direction orthogonal to the insertion direction of the modular plug. The junction box 20 is disposed outside the junction box in a state of 20, so that the simple tool portion can be prevented from hitting each junction board. According to a fifth invention, in the first to fourth inventions, the simple tool section presses the electric wire into the crimping groove by pressing the surface of the protective cover, because the protective cover is formed on the surface that presses the protective cover. -19- 200428709 where the finger is placed

According to a sixth invention, in the first to fifth inventions, the protective cover is provided at a position corresponding to each of the terminal boards so that each of the electric wires can be pressed into the front ends of the crimping grooves. Therefore, as in the conventional case where the wires are simultaneously pressed into all the wiring boards to perform the wiring operation, a commonly used tool such as pliers can also be used to carry out the wiring work of pressing the wires into all the wiring boards at the same time. The effect of choosing a method of wiring work. 10 The seventh invention adopts the structure of the sixth invention. An even-numbered pair of the terminal board is provided on the junction box, and an even-numbered pair of the front end portion is provided on the protective cover. The protective cover is divided into separate portions of the two half protective covers with equal logarithms in the front end portion. Therefore, by dividing the protective cover and pressing the surface of the half protective cover 15 on one side, the electric wires are simultaneously pressed. After inserting the crimping grooves of half of the terminal boards of all the terminal boards, by pressing the surface of the other half of the protective cover, you can also press the wires into the crimping grooves of the remaining half of the terminal boards at the same time. This has the effect of increasing the choice of a method of wiring work. 20 -20- 200428709 Description of the invention If stomach [Brief description of the drawing] The first figure is an explanatory diagram of the wiring work in this embodiment.
