固定手段22としては、電線10の、端子13の圧着部14を固定するクランプなどが用いられる。また、固定手段23としては、電線10の被覆材12を固定するクランプなどが用いられる。
注入手段24としては、上記の圧着部14において、導体11と被覆材12との境界近傍に、流動性を有した流動性止水剤を定量注入(滴下)するためのノズル25を、その先端に有した注入器が用いられる。
そして、止水剤供給手段20によって、電線10の端子13の圧着部14において導体11と被覆材12との境界近傍(図1Aと図1Bとの破線部)に流動性止水剤を供給する。
上型31には、電線10の端子13と、圧着部14およびその近傍とを収容するための第一凹部33と;電線10の端子13が圧着固定されていない側の端末を収容するための第二凹部34と;が設けられている。
下型32には、電線10の端子13と、圧着部14およびその近傍とを収容するための第三凹部35と;電線10の端子13が圧着固定されていない側の端末を収容するための第四凹部36と;が設けられている。
さらに、第三凹部35の周囲と第四凹部36の周囲は、パッキンなどの封止部材38で囲まれている。
これらのガイド溝43,44の大きさは、電線10の被覆部を隙間無く係止するために、その被覆部の外径に応じて適宜調整される。
そして、この空気導入管45の、下型32と連設している側とは反対側の端末には、加圧手段(図示略)が接続されている。この加圧手段は、第一収容部39内に空気を送り込み、第一収容部39内を高圧雰囲気とする。これにより、第一収容部39内に収容した電線10の端子13が圧着固定されている一方の端末側から、他方の端末側に向けて、被覆材12の内側、すなわち、導体11及び被覆材12の間と、導体11をなす複数本の導線の間とに流動性止水剤を浸透させる。この加圧手段としては、例えば、エアコンプレッサーなどの圧縮空気発生装置などが用いられる。
圧力制御手段46としては、例えば、0MPa~0.5MPaの範囲で空気の圧力を、時間とともに任意に調整可能な電空レギュレータなどの電磁弁が用いられる。
流量検出手段47としては、一般的な空気の流量計が用いられる。
そして、この空気排出管48の中途には、電線10の端子13が圧着固定されている側とは反対側の端末から漏れ出した空気の流量を検出する、流量検出手段49が設けられている。
流量検出手段49としては、一般的な空気の流量計が用いられる。
圧力検出手段50としては、一般的な、検出部としての圧力センサを有する圧力計が用いられる。
一方、下型32の側面32a,32bには、上型31と下型32とを合わせた状態で、上記の上型31の突部51,51方向に回転可能に軸止された係止部52,52が設けられている。
すなわち、上型31と下型32とを合わせて、上記の突部51,51に、係止部52,52を係止することにより、下型32に対して上型31を固定することができる。
一方、下型32の正面32cには、この正面32cと垂直な方向に突出した突部54が設けられている。さらに、この突部54には、回転軸56により軸止され、上型31と下型32とを合わせ状態で、上記の上型31の突部53の上面53aと平行な方向に回転可能な係止部材55が設けられている。この係止部材55は、回転軸56を境にして、短い部分と長い部分とからなる。短い部分は、突部53に係止される係止部55aであり、長い部分は、この係止部材55を回転させる際に握るための把持部55bである。
なお、この実施形態では、第一収容部39および第二収容部40を密閉するための密閉手段は、上記の突部53と、突部54と、係止部55と、回転軸56とから構成されている。
すなわち、上型31と下型32とを合わせ、係止部材55を回転させて、上記の突部53に、係止部55aを係止する。これにより、下型32と上型31との密着度が増し、第一収容部39と第二収容部40とを密閉することができる。
次に、図2Aと、図2Bと、図5と、図6とを参照して、上述の電線端末の止水処理装置を用いた電線端末の止水処理方法を説明する。
まず、止水剤供給手段20のベース21に電線10をセットし、固定手段22,23により、端子13が圧着固定された側の電線端末を固定する。
次いで、ベース21に固定された電線10の、端子13の圧着部14において、導体11と被覆材12との境界近傍に、注入手段24により所定量の流動性止水剤を注入(滴下)する(止水剤供給工程)。
流動性止水剤の注入(滴下)量は、電線10の導体11の長さや直径(線径)に応じて、適宜調整される。
また、金型30の下型32の第二収容部40に、電線10の端子13が圧着固定されていない側の端末を収容するとともに、ガイド溝44に電線10の被覆部を嵌め込む。
次いで、上型31の突部51,51に、係止部52,52を係止することにより、下型32に対して上型31を固定する。
これにより、第一収容部39内に送り込まれる空気の圧力を、電線10の導体11の長さや直径(線径)に応じて、適宜調整する。
これにより、上型31と下型32とを合わせた状態で、第一収容部39内の様子を目視観察することなく、第一収容部39内にて流動性止水剤が電線10の被覆材12の内側に浸透しているか否かを確認することができる。
この流量検出工程において、電線10の端子13が圧着固定されている側とは反対側の端末からの空気の漏れ出しが検出された場合、流動性止水剤が電線10の被覆材12の内側、すなわち、導体11及び被覆材12の間と、導体11をなす複数本の導線の間とに正常に浸透していないと判断できる。一方、空気の漏れ出しが検出されなかった場合、流動性止水剤が電線10の被覆材12の内側、すなわち、導体11及び被覆材12の間と、導体11をなす複数本の導線の間とに正常に浸透していると判断できる。
なお、第一収容部39内の圧力が一定になるように、加圧手段から第一収容部39内に送り込まれる空気の量を圧力制御手段46で制御する場合、第一収容部39内へ送り込まれる空気の流量を流量検出手段47により検知して、流動性止水剤が電線10の被覆材12の内側、すなわち、導体11及び被覆材12の間と、導体11をなす複数本の導線の間とに正常に浸透しているか否かを判断することができる。
