Description

本発明は、例えば自動車のエンジンルームと車室側とを接続するシールド電線のアース用のドレン線の素線間の止水を行わせるシールド電線の止水構造に関するものである。   The present invention relates to a water stop structure for a shielded electric wire for stopping water between the strands of a drain wire for grounding a shielded electric wire that connects, for example, an engine room and a vehicle compartment side of an automobile.

図10(a)(b)は、従来の電線の止水構造の一形態を示すものである(特許文献1参照)。   10 (a) and 10 (b) show one form of a conventional water stop structure for electric wires (see Patent Document 1).

この構造は、図10(a)の如く、電線71の一端に丸型板端子(LA端子)72を接続し、電線71の他端に防水コネクタ73を接続し、電線71の中間部を皮剥きして芯線部71aを露出させ、図10(b)の如く、芯線部71aに分岐線74をジョイント接続すると共に、芯線部71aの周囲にシール剤75を充填して防水フィルム76で封止したものである。   In this structure, as shown in FIG. 10A, a round plate terminal (LA terminal) 72 is connected to one end of an electric wire 71, a waterproof connector 73 is connected to the other end of the electric wire 71, and an intermediate portion of the electric wire 71 is cut off. The core wire portion 71a is exposed by peeling, and the branch wire 74 is jointly connected to the core wire portion 71a as shown in FIG. 10B, and a sealing agent 75 is filled around the core wire portion 71a and sealed with a waterproof film 76. It is a thing.

芯線部71aは複数の素線で構成され、シール剤75で各素線間が防水され、水が素線間を毛細管現象で伝わることが抑止される。図10(a)の端子72は非防水であり、自動車のエンジンルーム内のボディパネル等に接続され、防水コネクタ73は車室側に配置される。   The core wire portion 71a is composed of a plurality of strands. The sealant 75 waterproofs the strands, and water is prevented from being transmitted between the strands by a capillary phenomenon. The terminal 72 in FIG. 10A is non-waterproof, and is connected to a body panel or the like in an automobile engine room, and the waterproof connector 73 is disposed on the vehicle compartment side.

上記以外の電線の止水構造として、例えば特許文献2には、電線の芯線部を挿入する端子内に導電性接着剤を充填したことが記載され、特許文献3には、丸型板端子の電線接続部分の外周に接着剤付きの熱収縮チューブを被せることが記載されている(図示せず)。   For example, Patent Document 2 describes that a conductive adhesive is filled in a terminal into which a core wire portion of an electric wire is inserted, and Patent Document 3 describes a round plate terminal as a water-stop structure other than the above. It is described that a heat-shrinkable tube with an adhesive is placed on the outer periphery of the electric wire connecting portion (not shown).

図11は、本出願人が実施している既存のシールド電線の止水構造の一形態を示すものである。   FIG. 11 shows one form of a water-stop structure for an existing shielded electric wire implemented by the present applicant.

この構造は、シールド電線1のアース用のドレン線2に突き合わせ用の中間電線77を介して延長電線(一般電線)5’をジョイント接続し、ドレン線2と中間電線77との接続部78は非防水とし、中間電線77と延長電線5’との接続部79は素線間止水用の接着剤と熱収縮チューブとで防水し、延長電線5’の先端側の端子9とシールド電線1の主線3側の端子19とを各防水ゴム栓10と共に防水コネクタ11内に挿入するものである。   In this structure, an extension wire (general wire) 5 ′ is joint-connected to the grounding drain wire 2 of the shielded wire 1 through an abutting intermediate wire 77, and a connecting portion 78 between the drain wire 2 and the intermediate wire 77 is The connection portion 79 between the intermediate wire 77 and the extension wire 5 ′ is waterproofed with an adhesive for waterproofing between strands and a heat-shrinkable tube, and the terminal 9 on the distal end side of the extension wire 5 ′ and the shield wire 1 The terminal 19 on the main line 3 side is inserted into the waterproof connector 11 together with each waterproof rubber plug 10.

中間電線77を用いることで、ドレン線2と延長電線5’とが分断されて、ドレン線2の各素線間を伝わる水が延長電線5’の各素線間に浸入することが阻止される。これにより、エンジンルーム内の気圧や温度変化等に伴う素線間の呼吸作用による水の浸入が防止される。   By using the intermediate electric wire 77, the drain wire 2 and the extended electric wire 5 ′ are separated, and water transmitted between the strands of the drain wire 2 is prevented from entering between the individual wires of the extended electric wire 5 ′. The This prevents water from entering due to the breathing action between the wires due to changes in atmospheric pressure and temperature in the engine room.

しかしながら、上記従来の図11のシールド電線の止水構造にあっては、中間電線77とジョイント端子とジョイントテープと、熱溶着等の接続手段と、接着剤と熱収縮チューブといった多くの部品やジョイント接続工数及び止水工数を必要とし、コスト高になるという問題があった。また、延長電線との防水作業性を上げるために中間電線77を長めに形成しなければならず、ドレン線2と中間電線77と延長電線5’との総長さが増大して、構造が肥大化・重量化するという問題があった。   However, in the conventional water blocking structure of the shielded wire shown in FIG. 11, the intermediate wire 77, the joint terminal, the joint tape, the connection means such as heat welding, the adhesive, the heat shrinkable tube, and other parts and joints. There is a problem in that it requires a connection man-hour and a water stop man-hour, resulting in high costs. Moreover, in order to improve the waterproof workability with the extension wire, the intermediate wire 77 must be formed longer, the total length of the drain wire 2, the intermediate wire 77, and the extension wire 5 'increases, and the structure is enlarged. There was a problem of increasing the weight and weight.

本発明は、上記した点に鑑み、ドレン線から延長電線への素線間の水の浸入を確実に防止することができることは勿論のこと、ドレン線と延長電線との接続や防水処理を少ない部品と工数でコンパクトに行うことができるシールド電線の止水構造を提供することを目的とする。   In view of the above points, the present invention can reliably prevent water from entering between the strands from the drain wire to the extension wire, as well as reducing the connection between the drain wire and the extension wire and waterproofing treatment. It aims at providing the waterproof structure of the shield electric wire which can be performed compactly by parts and man-hours.

上記目的を達成するために、本発明の請求項1に係るシールド電線の止水構造は、シールド電線のドレン線に端子を介して延長電線の一端部を接続し、該延長電線の他端部を防水コネクタ内に配置する構造において、前記端子が、前記延長電線の一端部を液密に挿入するための筒状部と、該筒状部内に該一端部を閉じ込める空間を形成する封止壁とを備え、該一端部と前記ドレン線とが該封止壁を介して隔絶されたことを特徴とする。   In order to achieve the above-mentioned object, a water stop structure for a shielded wire according to claim 1 of the present invention is such that one end of an extension wire is connected to the drain wire of the shield wire via a terminal, and the other end of the extension wire. In the structure in which the terminal is disposed in the waterproof connector, the terminal forms a cylindrical part for liquid-tightly inserting one end part of the extension wire, and a sealing wall that forms a space for confining the one end part in the cylindrical part The one end and the drain wire are isolated from each other through the sealing wall.

上記構成により、ドレン線の内部(例えば各素線間や編組線間)を伝わった水が端子の封止壁で遮られて延長電線の一端部への水の伝播が阻止される。これにより、ドレン線からの水が延長電線を伝わって防水コネクタ内に浸入することが防止される。延長電線の一端部は例えばその絶縁被覆の外周面が筒状部の内周面に弾性的に液密に接触(密着)する。あるいは、絶縁被覆と筒状部とをシール剤や接着剤やゴム栓等の防水手段を介して液密化することも可能である。   With the above configuration, the water transmitted through the drain wire (for example, between the individual wires or between the braided wires) is blocked by the sealing wall of the terminal, and the water is prevented from propagating to one end of the extension wire. This prevents water from the drain wire from passing through the extension wire and entering the waterproof connector. At one end of the extension wire, for example, the outer peripheral surface of the insulating coating is elastically liquid-tightly contacted (adhered) to the inner peripheral surface of the cylindrical portion. Alternatively, the insulating coating and the cylindrical portion can be liquid-tight via a waterproofing means such as a sealing agent, an adhesive, or a rubber plug.

請求項2に係るシールド電線の止水構造は、請求項1記載のシールド電線の止水構造において、前記封止壁から前記筒状部とは反対側に突出した端子部に前記ドレン線側の端子部又はドレン線が接続されたことを特徴とする。   The water stop structure for a shielded electric wire according to claim 2 is the water stop structure for the shielded electric wire according to claim 1, wherein a terminal portion protruding from the sealing wall to the side opposite to the tubular portion is provided on the drain wire side. A terminal portion or a drain wire is connected.

上記構成により、端子の封止壁から突出した端子部(例えば雄端子部)にドレン線側の端子部(雌端子部)が挿入接続兼係止され、あるいは、端子の封止壁から突出した端子部(例えば前記筒状部を一方とした場合の他方の筒状部やオープンバレル部)にドレン線(露出芯線)が加締め等で接続される。他方の筒状部の開口は一方の筒状部の開口から大きく離間するので、筒状部に沿う水の沿面距離が増大し、ドレン線に沿う水が他方の開口から外部に出たとしても、一方の開口に届く心配はない。   With the above configuration, the drain wire side terminal portion (female terminal portion) is inserted and connected and locked to the terminal portion (for example, male terminal portion) protruding from the terminal sealing wall, or protruded from the terminal sealing wall. A drain wire (exposed core wire) is connected to a terminal portion (for example, the other cylindrical portion or the open barrel portion where the cylindrical portion is one side) by caulking or the like. Since the opening of the other cylindrical part is far away from the opening of the one cylindrical part, the creeping distance of the water along the cylindrical part increases, and even if the water along the drain line comes out of the other opening. No worries about reaching one of the openings.

請求項3に係るシールド電線の止水構造は、請求項1記載のシールド電線の止水構造において、前記端子としての導電パイプの中間に前記封止壁又は封止壁としての封止ゴム栓が設けられ、該導電パイプの一方の前記筒状部に前記延長電線の一端部、他方に前記ドレン線がそれぞれ挿入接続されたことを特徴とする。   The waterproof structure of the shielded electric wire according to claim 3 is the waterproof structure of the shielded electric wire according to claim 1, wherein the sealing wall or the sealing rubber plug as the sealing wall is provided in the middle of the conductive pipe as the terminal. One end of the extension wire is inserted into one cylindrical portion of the conductive pipe, and the drain wire is inserted and connected to the other.

上記構成により、導電パイプが一体又は別体の封止壁又は別体の封止ゴム栓で区画され、導電パイプの他方に挿入されて加締め等で接続されたドレン線を伝わる水が封止壁又は封止ゴム栓で遮断され、導電パイプの一方に挿入された延長電線の一端部への水の伝播が封止壁又は封止ゴム栓で阻止される。封止ゴム栓も封止壁の一種である。導電パイプの他方の筒状部の開口は一方の筒状部の開口から大きく離間するので、筒状部に沿う水の沿面距離が増大し、ドレン線を伝わる水が他方の開口から外部に出たとしても、一方の開口に届く心配はない。   With the above configuration, the conductive pipe is partitioned by an integral or separate sealing wall or a separate sealing rubber plug, and the water transmitted through the drain wire inserted into the other side of the conductive pipe and connected by caulking or the like is sealed. Water is blocked by a wall or a sealing rubber stopper, and the propagation of water to one end of the extension wire inserted into one of the conductive pipes is blocked by the sealing wall or the sealing rubber stopper. A sealing rubber stopper is also a kind of sealing wall. Since the opening of the other cylindrical portion of the conductive pipe is greatly separated from the opening of the one cylindrical portion, the creeping distance of the water along the cylindrical portion is increased, and the water transmitted through the drain wire is discharged to the outside from the other opening. Even so, there is no worry of reaching one of the openings.

請求項4に係るシールド電線の止水構造は、請求項1〜3の何れかに記載のシールド電線の止水構造において、前記筒状部の開口と前記延長電線の一端部の外周面とがシール剤や接着剤や防水ゴム栓等の防水手段で液密に封止されたことを特徴とする。   The water stop structure for a shielded wire according to claim 4 is the water stop structure for a shielded wire according to any one of claims 1 to 3, wherein the opening of the tubular portion and the outer peripheral surface of one end of the extension wire are It is characterized by being liquid-tightly sealed with a waterproofing means such as a sealing agent, an adhesive, or a waterproof rubber stopper.

上記構成により、ドレン線の素線間止水とは別に、筒状部の延長電線挿入用の開口から筒状部内への外部の水の浸入がシール剤や接着剤や防水ゴム栓等といった防水手段で確実に防止される。   With the above configuration, in addition to the drain water between drain wires, the penetration of external water from the opening for inserting the extension wire into the cylindrical portion into the cylindrical portion is waterproof, such as a sealant, adhesive, waterproof rubber plug, etc. It is reliably prevented by means.

請求項1記載の発明によれば、端子の封止壁によってドレン線から延長電線への素線間浸水を確実に阻止することができ、これにより、防水コネクタの電気的接続の信頼性を高めることができる。また、従来の中間電線やそのジョイント接続が不要であるから、ドレン線と延長電線との接続や防水処理を少ない部品と工数で低コストに行うことができると共に、ドレン線と延長電線との総長さを短縮して構造をコンパクト化することができる。   According to the first aspect of the present invention, inter-element flooding from the drain wire to the extension wire can be reliably prevented by the sealing wall of the terminal, thereby improving the reliability of the electrical connection of the waterproof connector. be able to. In addition, since conventional intermediate wires and their joints are not required, connection between drain wires and extension wires and waterproofing can be performed at low cost with few parts and man-hours, and the total length of drain wires and extension wires The structure can be made compact by shortening the length.

請求項2記載の発明によれば、例えば延長電線に接続した端子の端子部にドレン線側の端子部を挿入して接続係止させることで、延長電線とドレン線との接続を容易に行うことができる。あるいは、延長電線に接続した端子の端子部にドレン線を直接加締め等で接続させることで、ドレン線側の端子部を不要として部品点数をさらに削減することができる。   According to the second aspect of the invention, for example, the drain wire side terminal portion is inserted into the terminal portion of the terminal connected to the extension wire, and the connection is locked, thereby easily connecting the extension wire and the drain wire. be able to. Alternatively, by connecting the drain wire directly to the terminal portion of the terminal connected to the extension wire by caulking or the like, the terminal portion on the drain wire side is unnecessary, and the number of parts can be further reduced.

請求項3記載の発明によれば、導電パイプ内に封止壁又は封止ゴム栓を介して延長電線とドレン線との両方を収容することで、導電パイプ内のドレン線内を伝わる水から延長電線までの沿面距離を増して、延長電線への水の伝播を確実に防止することができる。また、別体の封止壁や封止ゴム栓を用いることで、端子の形成を容易に行うことができる。   According to the invention described in claim 3, by accommodating both the extension wire and the drain wire through the sealing wall or the sealing rubber plug in the conductive pipe, the water transmitted through the drain wire in the conductive pipe can be used. The creepage distance to the extension wire can be increased, and the propagation of water to the extension wire can be reliably prevented. Further, the terminal can be easily formed by using a separate sealing wall or sealing rubber plug.

請求項4記載の発明によれば、ドレン線の素線間止水とは別に、筒状部の延長電線挿入用の開口から筒状部内への外部の水の浸入をシール剤や接着剤や防水ゴム栓等といった防水手段で確実に防止することができる。   According to the invention described in claim 4, in addition to the inter-strand water stop of the drain wire, the entry of external water into the cylindrical portion from the opening for inserting the extension wire in the cylindrical portion is prevented with a sealing agent, an adhesive, It can be reliably prevented by waterproof means such as a waterproof rubber stopper.

図1の如く、封止壁14の内面側に延長電線5の基端が位置し、封止壁14の外面側にドレン線2の先端が位置し、封止壁14で延長電線5の基端とドレン線2の先端とが隔絶されることで、雌端子6側から筒状部13内への水の浸入が阻止される。   As shown in FIG. 1, the proximal end of the extension wire 5 is located on the inner surface side of the sealing wall 14, and the distal end of the drain wire 2 is located on the outer surface side of the sealing wall 14. Since the end and the tip of the drain wire 2 are isolated from each other, the intrusion of water from the female terminal 6 side into the tubular portion 13 is prevented.

また、延長電線5の基端側の絶縁被覆8aの外周面が筒状部13の内周面に弾性的に密着し、好ましくは絶縁被覆8aの外周面が筒状部13の内周面13aにシール剤や接着剤で接着されることで、絶縁被覆8に沿う筒状部13内への水の浸入が防止される。   In addition, the outer peripheral surface of the insulating coating 8a on the proximal end side of the extension wire 5 is elastically adhered to the inner peripheral surface of the cylindrical portion 13, and preferably the outer peripheral surface of the insulating coating 8a is the inner peripheral surface 13a of the cylindrical portion 13. By adhering to each other with a sealing agent or an adhesive, water can be prevented from entering the cylindrical portion 13 along the insulating coating 8.

延長電線5の先端側の端子9は雄端子でも雌端子でもよく(図では端子9を簡略化して示している)、延長電線5に圧着接続されている(圧接接続する場合は絶縁被覆8の皮剥きは不要である)。防水ゴム栓10は、延長電線5の絶縁被覆8の表面に密着する内径部(図示せず)と、絶縁樹脂製のコネクタハウジング(符号11で代用)の端子収容室(図示せず)の内面に密着する外径部(リップ)10aとを有している。端子9は例えば左右各一対の前側の芯線圧着片と後側の絶縁被覆圧着片(図示せず)とを有し、絶縁被覆圧着片は防水ゴム栓10の先端部を絶縁被覆8に共締め固定する。主電線3の先端側の端子19と防水ゴム栓10も同様のものである(主端子19をアース端子9よりも大型とすることも可能である)。   The terminal 9 on the distal end side of the extension wire 5 may be a male terminal or a female terminal (the terminal 9 is shown in a simplified manner in the figure), and is crimped to the extension wire 5 (in the case of pressure connection, the insulation coating 8 is provided). Skinning is not necessary). The waterproof rubber plug 10 includes an inner diameter portion (not shown) that is in close contact with the surface of the insulating coating 8 of the extension wire 5 and an inner surface of a terminal housing chamber (not shown) of an insulating resin connector housing (represented by reference numeral 11). And an outer diameter portion (lip) 10a that is in close contact with each other. The terminal 9 has, for example, a pair of left and right front core wire crimping pieces and a rear insulation coating crimping piece (not shown). The insulation coating crimping piece is fastened together with the insulating coating 8 at the tip of the waterproof rubber plug 10. Fix it. The terminal 19 on the front end side of the main electric wire 3 and the waterproof rubber plug 10 are the same (the main terminal 19 can be made larger than the ground terminal 9).

両端子9,19は両防水ゴム栓10と共にコネクタハウジング11の各端子収容室内に挿入されて端子収容室内の係止ランス(図示せず)で係止され、少なくともコネクタハウジング11と各端子9,19と各防水ゴム栓10とで防水コネクタが構成される。シールド電線1は、通電用の主電線3とアース用のドレン線2と、両電線2,3を覆う絶縁外皮4とを備えている。ドレン線2として編組線を用いる場合、編組線は主電線3を覆い、編組線を絶縁外皮4が覆う。   Both terminals 9 and 19 are inserted into the terminal housing chambers of the connector housing 11 together with the waterproof rubber plugs 10 and locked by locking lances (not shown) in the terminal housing chamber, and at least the connector housing 11 and the terminals 9 and 9 19 and each waterproof rubber plug 10 constitute a waterproof connector. The shielded electric wire 1 includes a main electric wire 3 for energization, a drain wire 2 for grounding, and an insulating sheath 4 that covers both electric wires 2 and 3. When a braided wire is used as the drain wire 2, the braided wire covers the main electric wire 3, and the braided wire is covered by the insulating sheath 4.

図1の実施形態によれば、従来の中間電線が不要となるから、ドレン線2と延長電線5との総長さ(全長)が短縮される。ドレン線2への雌端子6の接続(圧着)はドレン線2が短くても行うことができる。また、延長電線5の基端部5a側を従来のように折り返さず、延長電線5よりも絶縁被覆がなく柔軟なドレン線2の先端側を折り返せばよいから(折り返し部を符号2bで示す)、接続作業性が良い。延長電線5を主電線3よりも短く形成すれば、ドレン線2をS字状に折り返す必要もなくなる。   According to the embodiment of FIG. 1, the conventional intermediate wire is not required, so the total length (full length) of the drain wire 2 and the extension wire 5 is shortened. The connection (crimping) of the female terminal 6 to the drain wire 2 can be performed even if the drain wire 2 is short. Further, the proximal end portion 5a side of the extension wire 5 is not folded back as in the conventional case, and the distal end side of the flexible drain wire 2 having no insulation coating than the extension wire 5 may be folded back (the folded portion is indicated by reference numeral 2b). Good connection workability. If the extension wire 5 is formed shorter than the main wire 3, it is not necessary to fold the drain wire 2 into an S shape.

また、延長電線5へのクローズドバレル端子12の圧着と、ドレン線2への雌端子6の圧着とは自動機で行うことができ、且つクローズドバレル端子12と雌端子6との接続も自動機で行うことができる。また、延長電線5としてアルミ電線を用いる場合、クローズドバレル端子12内で湿気を防いで、アルミ電線の基端部5aの酸化皮膜の発生を防止することができる。これらの効果は後述の各実施形態においても同様に奏されるものである。   The crimping of the closed barrel terminal 12 to the extension wire 5 and the crimping of the female terminal 6 to the drain wire 2 can be performed by an automatic machine, and the connection between the closed barrel terminal 12 and the female terminal 6 is also automated. Can be done. Moreover, when using an aluminum electric wire as the extension electric wire 5, moisture can be prevented in the closed barrel terminal 12, and the generation | occurrence | production of the oxide film of the base end part 5a of an aluminum electric wire can be prevented. These effects are also exhibited in each embodiment described later.
