Description

本発明は簡易防水コネクタに関し、詳しくは、自動車に配索するワイヤハーネスの端末に接続するコネクタに浸水が生じるのを防止するものである。   The present invention relates to a simple waterproof connector, and more particularly, to prevent water from entering a connector connected to a terminal of a wire harness arranged in an automobile.

浸水領域に配索するワイヤハーネス端末には防水コネクタが接続されており、該防水コネクタはコネクタハウジングに防水フードを付設したり、ワイヤハーネスの各電線に防水用ゴム栓を取り付け、コネクタ内部への浸水を確実に防止できる構造とされている。そのため、構造が複雑になり、重量が増加し、かつ、部品点数および取付作業手数がかかりコスト高になる。   A waterproof connector is connected to the wire harness terminal routed in the flooded area. The waterproof connector is provided with a waterproof hood attached to the connector housing, or a waterproof rubber plug is attached to each wire of the wire harness. It is structured to prevent flooding reliably. Therefore, the structure is complicated, the weight is increased, the number of parts and the number of mounting operations are increased, and the cost is increased.

また、近時、軽量化と低コスト化より、電線の芯線を銅系金属に代えてアルミニウム系金属が採用されつつあるが、銅系金属からなる端子との圧着接続部分は異種金属の接触となり腐食が発生しやすくなる。さらに、該異種金属の接触部分に水滴が付着すると腐食は急激に広い範囲で発生する。   In recent years, aluminum-based metals have been adopted instead of copper-based metals for lighter weight and lower cost, but the crimped connection parts with terminals made of copper-based metal are in contact with dissimilar metals. Corrosion is likely to occur. Further, when water droplets adhere to the contact portion of the different metal, corrosion occurs rapidly in a wide range.

よって、防水コネクタが必須となる浸水領域に配置するコネクタではないが、車室内での飲料水のこぼれ等で不用意に水がかかる恐れがある箇所に、前記アルミニウム系金属の芯線と接続した端子を挿入係止するコネクタを配置する場合、該コネクタを簡易防水コネクタとする必要がある。   Therefore, it is not a connector to be placed in a flooded area where a waterproof connector is essential, but a terminal connected to the aluminum metal core wire at a place where water may accidentally be splashed due to spilled drinking water in the passenger compartment. When a connector that inserts and locks the connector is disposed, the connector needs to be a simple waterproof connector.

この種の簡易防水コネクタとして、本出願人は図９（Ａ）（Ｂ）に示す防水コネクタを特開平７−７３９２６号公報（特許文献１）で提供すると共に、図１０（Ａ）（Ｂ）に示す防水コネクタを特開２００４−１４６１８１号公報（特許文献２）で提供している。   As this type of simple waterproof connector, the present applicant provides a waterproof connector shown in FIGS. 9A and 9B in Japanese Patent Laid-Open No. 7-73926 (Patent Document 1), and FIGS. 10A and 10B. JP, 2004-146181, A (patent documents 2) provides the waterproof connector shown in these.

前記特許文献１の防水コネクタでは、コネクタハウジングに取り付けた防水カバーに設けた各端子挿通穴に電線端末の端子を貫通している。即ち、特許文献１の防水コネクタでは電線端末の端子１２０をそれぞれ貫通する透穴１３０を設けた防水カバー１１０をコネクタハウジングに外嵌している。特許文献２の防水コネクタでは電線端末の端子１２０をそれぞれ貫通する端子挿入孔２０２を設けた一体型ゴム栓カバー２０１をコネクタハウジングに内嵌している。   In the waterproof connector of Patent Document 1, the terminal of the electric wire terminal is passed through each terminal insertion hole provided in the waterproof cover attached to the connector housing. That is, in the waterproof connector of Patent Document 1, the waterproof cover 110 provided with the through holes 130 penetrating the terminals 120 of the electric wire terminals is fitted on the connector housing. In the waterproof connector of Patent Document 2, an integrated rubber stopper cover 201 having terminal insertion holes 202 penetrating the terminals 120 of the electric wire terminals is fitted in the connector housing.

前記のように、従来の簡易防水コネクタでは、いずれも、電線端末に接続した端子をコネクタに嵌合している防水カバーの端子穴にそれぞれ先に通した後に、これら端子をコネクタの端子収容室に挿入係止している。このように、防水カバーをコネクタに先に取り付けているため、該防水カバーの各端子孔に電線端末の端子を通してコネクタ内に挿入する必要があり、作業手数がかかる問題がある。   As described above, in each of the conventional simple waterproof connectors, the terminals connected to the electric wire terminals are first passed through the terminal holes of the waterproof cover fitted to the connectors, and then these terminals are connected to the terminal receiving chamber of the connector. Is inserted and locked. As described above, since the waterproof cover is attached to the connector in advance, it is necessary to insert the terminal of the electric wire terminal into each terminal hole of the waterproof cover and insert it into the connector.

本発明は前記問題を解消するためになされたものであり、コネクタに電線端末の端子を挿入係止した後にコネクタに防水カバーを取り付け、該防水カバーに電線を一括して通してコネクタ内への浸水防止を図ることができる簡易防水コネクタを提供することを課題としている。   The present invention has been made to solve the above problems, and after inserting and locking the terminal of the electric wire terminal into the connector, a waterproof cover is attached to the connector, and the electric wires are collectively passed through the waterproof cover to the connector. An object of the present invention is to provide a simple waterproof connector that can prevent flooding.

前記課題を解決するため、本発明は、電線端末の端子を挿入係止したコネクタに後付けする防水材を備え、
前記防水材は樹脂製で、コネクタハウジングの端子挿入側の前面上部に押し当てられる上端連結枠部と、該上端連結枠部の下面に並列に垂設している差し込みピンを備えた櫛状防水材とし、
前記コネクタの端子収容室の前面側開口から引き出される電線群に前記櫛状防水材の差し込みピンを上方から差し込んで隣接する電線の間に挟みこんで該電線の外面に接触させる構造としていることを特徴とする簡易防水コネクタを提供している。 In order to solve the above problems, the present invention comprises a waterproof material that is retrofitted to a connector in which a terminal of an electric wire terminal is inserted and locked,
The waterproof material is made of resin, and has a comb-like waterproof structure having an upper end connecting frame portion pressed against the upper front surface of the connector housing on the terminal insertion side, and an insertion pin extending in parallel to the lower surface of the upper end connecting frame portion. Material,
Inserting the insertion pin of the comb-shaped waterproof material from above into an electric wire group drawn out from the front side opening of the terminal accommodating chamber of the connector, and sandwiching it between adjacent electric wires to make contact with the outer surface of the electric wire A simple waterproof connector is provided.

前記櫛状防水材は前記上端連結枠部をコネクタハウジングの前面上部に押し当てた位置で、隣接する前記差し込みピンの間は挟み込む電線により押し広げられる寸法をあけると共に、該電線との接触位置より上部では隣接する差し込みピンの間はスリット状隙間とし、かつ、各差し込みピンは下端に向けて収斂する方向に傾斜する形状とし、さらに、各差し込みピンは電線接触時に腰折れせずに傾斜しながら差し込まれる強度を有するものとしている。即ち、櫛状防水材の差し込みピンをコネクタから引き出される電線群に上方から差し込む過程で、差し込みピンを樹脂製として硬度を持たせ、電線と接触しても腰折れすることなく、隣接する電線の間に差し込むことができる強度を持たせている。   The comb-shaped waterproofing material is opened at a position where the upper end connecting frame portion is pressed against the front upper part of the connector housing, and is opened by a wire inserted between adjacent insertion pins. In the upper part, a slit-like gap is formed between adjacent insertion pins, and each insertion pin is inclined to converge toward the lower end. It is assumed that it has the strength. That is, in the process of inserting the insertion pin of the comb-like waterproof material into the electric wire group drawn out from the connector from above, the insertion pin is made of resin and has hardness so that it does not break even if it comes in contact with the electric wire, and between adjacent electric wires It has the strength that can be plugged into.

前記のように、本発明では、コネクタに電線端末の端子を挿入係止後に、該コネクタの端子挿入側前面に沿わせてコネクタから引き出される電線群に櫛状防水材の差し込みピンを差し込んでいる。言い換えると、櫛状防水材の差し込みピンを上方から電線群の間に差し込んで行く過程で、隣接する差し込みピンの間の電線通し空間に各電線を一括して通すことができる。よって、従来のコネクタに先付けされた防水カバーの電線通し穴に電線をそれぞれ挿通する作業が必要がある防水コネクタと比較して電線の通し作業を非常に簡単にでき、作業を短時間で効率よく行うことができる。   As described above, in the present invention, after inserting and locking the terminal of the electric wire terminal into the connector, the insertion pin of the comb-like waterproof material is inserted into the electric wire group drawn out from the connector along the front side of the terminal insertion side of the connector. . In other words, in the process of inserting the insertion pin of the comb-shaped waterproof material between the electric wire groups from above, the electric wires can be collectively passed through the electric wire passing space between the adjacent insertion pins. Therefore, compared to conventional waterproof connectors that require the work of inserting the wires into the wire holes of the waterproof cover that is attached to the conventional connector, the work of passing the wires can be made much easier and the work can be done quickly and efficiently. It can be carried out.

また、コネクタの端子収容室の開口より引き出された位置の電線の外面に前記差し込みピンを接触させることにより、上方からコネクタ前面に沿って垂れ落ちてくる水滴および電線外面を伝ってくる水滴を前記差し込みピンで受け止め、水滴がコネクタの端子収容室（キャビテイ）内に端子挿入用開口から浸水するのを防止することができる。かつ、隣接する差し込みピンを押し開いて電線を通すため、電線の太さ（電線径）が相違しても電線の外面に差し込みピンを押しあてて、水滴を受け止めることができる。よって、電線径の相違を吸収できる防水材となり、電線径の相違に応じる部品点数を削減できる。   In addition, by bringing the insertion pin into contact with the outer surface of the electric wire at a position drawn out from the opening of the terminal housing chamber of the connector, the water droplets dripping along the front surface of the connector from above and the water droplets traveling along the outer surface of the electric wire are It can be received by the insertion pin, and water droplets can be prevented from entering the terminal receiving chamber (cavity) of the connector from the terminal insertion opening. And since an adjacent insertion pin is pushed open and an electric wire passes, even if the thickness (electric wire diameter) of an electric wire differs, an insertion pin can be pressed against the outer surface of an electric wire, and a water drop can be received. Therefore, it becomes a waterproof material which can absorb the difference in the wire diameter, and the number of parts corresponding to the difference in the wire diameter can be reduced.

さらに、櫛状防水材は差し込みピンの間に挟みこむ複数の電線により支持され、該電線の端末に接続した端子をコネクタハウジング内に挿入係止して、これら電線をコネクタで支持していることより、コネクタハウジングの前面に前記櫛状防水材を接着剤や機械的固定手段で固定することなく取り付けることができる。   Further, the comb-like waterproof material is supported by a plurality of electric wires sandwiched between insertion pins, the terminals connected to the ends of the electric wires are inserted and locked in the connector housing, and these electric wires are supported by the connector Thus, the comb waterproof material can be attached to the front surface of the connector housing without being fixed by an adhesive or mechanical fixing means.

前記コネクタに接続する電線は、アルミニウム系金属からなる芯線を絶縁被覆で被覆している電線であり、該電線の端末で絶縁被覆を皮剥ぎして露出させた芯線に銅系金属からなる端子を圧着接続している場合に、本発明の簡易防水コネクタは好適に用いられる。   The electric wire connected to the connector is an electric wire in which a core wire made of an aluminum-based metal is covered with an insulating coating, and a terminal made of a copper-based metal is exposed to the core wire exposed by peeling off the insulating coating at the end of the electric wire. The simple waterproof connector of the present invention is preferably used when crimping is connected.

前記電線と端子の異種金属の接触部に水がかかると腐食が発生しやすくなる。そのため、前記電線端末の端子が挿入されるコネクタ内部への浸水を確実に防止して、腐食の発生を防止する必要がある。よって、非浸水領域であるが、乗員が水をこぼす等の要因で不用意に水滴が付着する恐れがある箇所に配置されるコネクタは、前記本発明の櫛状防水材を取り付けて簡易防水コネクタとし、コストおよび作業手数をかけずに確実に防水できる構造とすることが好ましい。   Corrosion is likely to occur when water is applied to the contact portion of the wire and terminal of the dissimilar metal. Therefore, it is necessary to reliably prevent water from entering the connector into which the terminal of the electric wire terminal is inserted, thereby preventing the occurrence of corrosion. Therefore, the connector disposed in a non-water-immersed area, but where the occupant may spill water or the like may be inadvertently attached with water droplets, attaches the comb waterproof material of the present invention and is a simple waterproof connector. It is preferable to have a structure that can be reliably waterproofed without cost and labor.

前記櫛状防水材の隣接する差し込みピンの隙間寸法は、電線と接触する位置で小径電線では小さくすると共に、大径電線では大きくし、
かつ、前記隣接する差し込みピンの隙間寸法を小さくする場合は、差し込みピンの表面に撥水剤塗布層を設け、または該櫛状防水材を撥水性樹脂製とする一方、
前記隣接する差し込みピンの隙間寸法を大きくする場合は、少なくとも電線を挟みこむ側面に羽毛状突片を密集させた吸水部を設けることが好ましい。 The gap between adjacent insertion pins of the comb-shaped waterproofing material is made smaller for a small-diameter electric wire at a position in contact with the electric wire, and larger for a large-diameter electric wire,
And when reducing the gap between adjacent insertion pins, a water repellent coating layer is provided on the surface of the insertion pin, or the comb waterproof material is made of a water repellent resin,
In the case of increasing the gap size between the adjacent insertion pins, it is preferable to provide a water-absorbing portion in which feather-shaped projecting pieces are densely arranged on at least the side surface sandwiching the electric wire.

前記のように、隣接する差し込みピンの隙間寸法が小さい場合は、該隙間に水滴が保持されないように、差し込みピンの表面の撥水剤塗布層で撥水することが好ましい。
一方、隣接する差し込みピンの隙間寸法が大きい場合は、水滴が溜まる空間が大きくなるため、該水滴を差し込みピンの表面から突設する羽毛状突片で吸水して、水滴がコネクタの端子収容室に浸入するのを防止することが好ましい。 As described above, when the gap between adjacent insertion pins is small, it is preferable that the water repellent coating layer on the surface of the insertion pin is water-repellent so that water droplets are not retained in the gap.
On the other hand, when the gap between adjacent insertion pins is large, the space in which the water droplets accumulate is large, so the water droplets are absorbed by the feather-shaped projecting pieces protruding from the surface of the insertion pin, and the water droplets are collected in the terminal housing chamber of the connector. It is preferable to prevent intrusion.

さらに、前記櫛状防水材の上端連結枠部に、傘部を一体に設け、または別体の傘部を取り付け、該傘部の一方側はコネクタハウジングの上面への搭載部とすると共に、他方側はコネクタハウジングより引き出される電線群の上方に位置させて、電線の外面への水滴の落下を防止する電線側傘部とすることが好ましい。   Further, an umbrella part is integrally provided on the upper end connecting frame part of the comb-shaped waterproof material, or a separate umbrella part is attached, and one side of the umbrella part is a mounting part on the upper surface of the connector housing, and the other The side is preferably positioned above the group of wires drawn out from the connector housing, and is preferably an electric wire umbrella that prevents water droplets from dropping onto the outer surface of the electric wire.

また、前記傘部の電線側傘部を電線群の配線方向へのガイド部となる方向に傾斜または湾曲させることが好ましい。例えば、コネクタハウジングから引き出す電線群を下向き傾斜させると、電線外面を伝う水滴を自重落下させて、コネクタハウジングの端子収容室に浸水するのを確実に防止できる。   Moreover, it is preferable to incline or curve the electric wire side umbrella part of the said umbrella part in the direction used as the guide part to the wiring direction of an electric wire group. For example, when the group of electric wires drawn out from the connector housing is inclined downward, it is possible to reliably prevent water droplets traveling on the outer surface of the electric wires from falling by their own weight and entering the terminal housing chamber of the connector housing.

前記櫛状防水材は連続物として成形しておき、コネクタに応じた長さに切断して用いることが好ましい。また、該櫛状防水材に傘部を付す場合も、一体または別体として連続成形しておき、切断して用いることが好ましい。即ち、コネクタ毎に専用の防水材を設ける必要はなく、安価に簡易防水コネクタを得ることができる。   It is preferable that the comb-like waterproof material is formed as a continuous material and is cut into a length corresponding to the connector. Moreover, when attaching an umbrella part to this comb-shaped waterproof material, it is preferable to continuously form it as an integral body or as a separate body, and to cut it. That is, it is not necessary to provide a dedicated waterproof material for each connector, and a simple waterproof connector can be obtained at a low cost.

本発明の簡易防水コネクタは、コネクタに電線端末の端子を挿入係止後に、櫛状防水材を後付けでコネクタに取り付け、該取り付け工程で櫛状防水材の差し込みピンを電線群に上方から差し込んでいく過程で電線をそれぞれ同時かつ一括で差し込みピンの間の電線通し部分に通すことができる。よって、従来のコネクタに先付けされた防水カバーの電線通し穴に電線をそれぞれ挿通する作業が必要がある防水コネクタと比較して電線の通し作業を非常に簡単にでき、作業を短時間で効率よく行うことができる。
かつ、コネクタ自体は非防水の汎用コネクタを用いることができると共に、櫛状防水材を簡単かつ安価に取得でき、製造コストを低減することができる。 In the simple waterproof connector of the present invention, after inserting and locking the terminal of the electric wire terminal into the connector, the comb waterproof material is attached to the connector by retrofitting, and the insertion pin of the comb waterproof material is inserted into the electric wire group from above in the attaching process. In the course of going, the wires can be simultaneously and collectively passed through the wire passing portion between the insertion pins. Therefore, compared to conventional waterproof connectors that require the work of inserting the wires into the wire holes of the waterproof cover that is attached to the conventional connector, the work of passing the wires can be made much easier and the work can be done quickly and efficiently. It can be carried out.
Moreover, a non-waterproof general-purpose connector can be used as the connector itself, and a comb-like waterproof material can be obtained easily and inexpensively, and the manufacturing cost can be reduced.

以下、本発明の簡易防水コネクタの実施形態を図面を参照して詳述する。
本発明の簡易防水コネクタ（以下、コネクタと略称する）は自動車内に配索されるワイヤハーネス端末に接続されると共に、乗員が持ち込む飲料水等がこぼれて浸水する可能性がある位置に配置するコネクタである。即ち、エンジンルーム内や床面下方等の雨水や路面の溜まり水、洗浄水が入りこむ浸水領域に配置する防水コネクタより簡易的に防水を図るコネクタである。 Hereinafter, embodiments of a simple waterproof connector of the present invention will be described in detail with reference to the drawings.
The simple waterproof connector (hereinafter abbreviated as “connector”) of the present invention is connected to a wire harness terminal that is routed in an automobile, and is disposed at a position where spilled drinking water or the like may be spilled. It is a connector. That is, the connector is designed to be waterproofed more easily than a waterproof connector disposed in a flooded area where rain water, road surface pool water, or cleaning water enters the engine room or below the floor.

図１乃至図４に示す第１実施形態では、図１（Ａ）〜（Ｃ）に示すように、コネクタ１のコネクタハウジング２の端子収容室（キャビテイ）３への水滴Ｑ（Ｑ１、Ｑ２、Ｑ３）の浸水を防止するため櫛状防水材１０を取り付けている。コネクタ１の端子収容室３内に浸水する水滴（Ｑ）として、コネクタハウジング２の上面２ａに垂れ落ちた水滴（Ｑ１）が端子挿入側開口２ｈを設けた前面２ｂに沿って流れ落ち、また該前面２ｂに沿う位置で上方から垂れ落ちてくる水滴（Ｑ２）、さらに、コネクタ１に接続する電線２０の外周面を伝ってくる水滴（Ｑ３）がある。これら水滴（Ｑ）がコネクタ１の端子収容室３内に侵入するのを防止するため櫛状防水材１０を取り付けている。   In the first embodiment shown in FIGS. 1 to 4, as shown in FIGS. 1A to 1C, water droplets Q (Q 1, Q 2, Q 2, Q 2, Q 2, Q 2) into the terminal housing chamber (cavity) 3 of the connector housing 2 of the connector 1. A comb-shaped waterproofing material 10 is attached to prevent the flooding of Q3). As water droplets (Q) immersed in the terminal accommodating chamber 3 of the connector 1, the water droplets (Q1) dropped on the upper surface 2a of the connector housing 2 flow down along the front surface 2b provided with the terminal insertion side opening 2h. There is a water drop (Q2) that hangs down from above at a position along 2b and a water drop (Q3) that travels along the outer peripheral surface of the electric wire 20 connected to the connector 1. In order to prevent these water droplets (Q) from entering the terminal accommodating chamber 3 of the connector 1, a comb-like waterproof material 10 is attached.

櫛状防水材１０は電線２０の端末の端子２５をコネクタ１の端子収容室３内に挿入した後にコネクタハウジング２に後付けで取り付けている。実施形態のコネクタ１は機器のコネクタ嵌合凹部に嵌合する雌コネクタである。なお、ワイヤハーネス端末に接続したコネクタ同士を嵌合する場合は、両方の雌雄コネクタの端子挿入側開口２ｈに櫛状防水材１０をそれぞれ取り付けるものとしている。また、アースジョイントコネクタ等に適用できる。   The comb-like waterproof material 10 is attached to the connector housing 2 after the terminal 25 of the electric wire 20 is inserted into the terminal accommodating chamber 3 of the connector 1. The connector 1 of the embodiment is a female connector that fits into a connector fitting recess of a device. In addition, when fitting the connectors connected to the wire harness terminal, the comb waterproof material 10 is attached to the terminal insertion side openings 2h of both male and female connectors, respectively. It can also be applied to earth joint connectors.

コネクタ１のコネクタハウジング２は樹脂成形品で、非防水用の汎用のコネクタとして汎用されているものである。該コネクタハウジング２は上下左右壁からなる外壁２ｃの内部に縦壁と横壁とからなる仕切壁２ｄを設け、上下２段で且つ左右方向に複数の端子収容室（所謂キャビテイ）３を備えている。本実施形態では、上段の端子収容室３Ｕと下段の端子収容室３Ｄは各段に６個の端子収容室を並設している。なお、コネクタ１は端子収容室３が１段であっても、３段以上であってもよく、かつ、並設する端子収容室の個数も限定されない。前記コネクタハウジング２は各端子収容室３内の底壁に端子係止用のランス（図示せず）を切り起こしで設け、端子挿入側開口２ｈから挿入する電線２０の端末の端子２５の係止穴に挿入係止するものとしている。   The connector housing 2 of the connector 1 is a resin-molded product and is widely used as a non-waterproof general-purpose connector. The connector housing 2 is provided with a partition wall 2d composed of a vertical wall and a lateral wall inside an outer wall 2c composed of upper, lower, left and right walls, and has a plurality of terminal housing chambers (so-called cavities) 3 in the upper and lower stages and in the left-right direction. . In the present embodiment, the upper terminal accommodating chamber 3U and the lower terminal accommodating chamber 3D have six terminal accommodating chambers arranged in parallel at each stage. The connector 1 may have one stage or three or more terminal accommodating chambers 3, and the number of terminal accommodating chambers arranged in parallel is not limited. The connector housing 2 is provided by cutting and raising a terminal locking lance (not shown) on the bottom wall of each terminal accommodating chamber 3 to lock the terminal 25 of the terminal of the electric wire 20 inserted from the terminal insertion side opening 2h. It is supposed to be inserted and locked in the hole.

図３に示す電線２０はアルミニウム系金属からなる芯線２０ａを絶縁被覆層２０ｂで被覆しているアルミ系電線からなる。該電線２０を端末側で絶縁被覆層２０ｂを皮剥ぎして芯線２０ａを露出させ、該芯線２０ａに銅系金属板からなる端子２５を加締め圧着して接続している。前記コネクタ１の全端子収容室３に電線２０の端末に圧着した端子２５を挿入係止するものとしている。   The electric wire 20 shown in FIG. 3 is made of an aluminum electric wire in which a core wire 20a made of an aluminum metal is covered with an insulating coating layer 20b. The insulation coating layer 20b is peeled off at the terminal side of the electric wire 20 to expose the core wire 20a, and a terminal 25 made of a copper-based metal plate is crimped and connected to the core wire 20a. The terminals 25 crimped to the ends of the electric wires 20 are inserted and locked in all the terminal accommodating chambers 3 of the connector 1.

前記櫛状防水材１０はポリエチレン、ポリプロピレン、ナイロン、テフロン（登録商標）等の樹脂で「櫛状」に形成した樹脂成形品からなる。該櫛状防水材１０は、コネクタハウジング２の端子挿入側の前面２ｂの上部に押し当てられる断面矩形状の上端連結枠部１１と、該上端連結枠部１１の下面に並列に垂設している差し込みピン１２を一体的に備えた形状としている。本実施形態ではＰＰ（ポリプロピレン製）とし、図２（Ｃ）に示すように、差し込みピン１２の表面にフッ素樹脂塗布層１２ｃを設けている。該櫛状防水材１０の幅方向Ｘの寸法はコネクタハウジング２の全幅寸法と同等とし、密に設ける前記差し込みピン１２でコネクタハウジング２の上下段の全端子収容室３の前面２ｂを覆う大きさとしている。   The comb-shaped waterproof material 10 is formed of a resin molded product formed in a “comb shape” with a resin such as polyethylene, polypropylene, nylon, Teflon (registered trademark). The comb-shaped waterproofing material 10 is provided in parallel with the upper end connection frame portion 11 having a rectangular cross section that is pressed against the upper portion of the front surface 2b on the terminal insertion side of the connector housing 2 and the lower surface of the upper end connection frame portion 11 in parallel. The insertion pin 12 is integrally provided. In the present embodiment, PP (made of polypropylene) is used, and as shown in FIG. 2C, a fluororesin coating layer 12c is provided on the surface of the insertion pin 12. The size of the comb waterproof material 10 in the width direction X is the same as the overall width of the connector housing 2, and the insertion pins 12 provided densely cover the front surface 2b of all the terminal accommodating chambers 3 in the upper and lower stages of the connector housing 2. It is said.

図２に示す櫛状防水材１０は、その上端連結枠部１１をコネクタハウジング２の上壁の前面全体に丁度押し当てられる大きさとしている。該上端連結枠部１１の下面から幅方向に密に並設する多数の差し込みピン１２は、上下２段の全端子収容室３の端子挿入側開口２ｈを覆う上下長さを有し、下端１２ｐに向けて収斂する方向に傾斜する形状としている。   The comb waterproof material 10 shown in FIG. 2 has a size that allows the upper end connecting frame portion 11 to be pressed just against the entire front surface of the upper wall of the connector housing 2. A number of insertion pins 12 densely arranged in the width direction from the lower surface of the upper end connection frame portion 11 have a vertical length that covers the terminal insertion side openings 2h of the upper and lower two-stage all terminal accommodating chambers 3 and have a lower end 12p. The shape is inclined in the direction of converging toward

前記差し込みピン１２は下端１２ｐよりコネクタ１から引き出される複数の電線２０に差し込まれ、図１（Ａ）に示すように、上端連結枠部１１がコネクタハウジング２の上壁前面に押し当てられた位置で挿入停止するものとしている。この位置で、隣接する差し込みピン１２、即ち、図１（Ｂ）中で差し込みピン１２−１と１２−２の間に上段の端子収容室３Ｕから引き出される電線２０ー１が差し挟まれ、電線２０−１の両側外面は差し込みピン１２−１と１２−２と接触しながら押し広げる。各差し込みピン１２は上端から前記電線２０−１の差し込み位置Ｈ１までは、隣接する差し込みピンとの間は殆ど空隙のないスリット状隙間としている。該位置Ｈ１から、挟み込む電線２０−１で押し広げても損傷および腰折れが発生しない隙間がある程度に下端１２ｐに向けて幅狭に傾斜させている。かつ、電線への差し込み時に差し込みピン１２が腰折れしたり、亀裂等の損傷が発生せずに、電線２０−１の外面に沿って傾斜して電線の間に差し込んでいく強度を有するものとしている。   The insertion pin 12 is inserted into a plurality of electric wires 20 drawn from the connector 1 from the lower end 12p, and the position where the upper end connecting frame portion 11 is pressed against the front surface of the upper wall of the connector housing 2 as shown in FIG. The insertion is supposed to stop. At this position, the adjacent insertion pin 12, that is, the electric wire 20-1 drawn from the upper terminal accommodating chamber 3U is inserted between the insertion pins 12-1 and 12-2 in FIG. The outer surfaces on both sides of 20-1 are spread while contacting the insertion pins 12-1 and 12-2. Each insertion pin 12 has a slit-like gap with almost no gap between the upper end and the insertion position H1 of the electric wire 20-1 between adjacent insertion pins. Even if the electric wire 20-1 is sandwiched from the position H1, it is inclined narrowly toward the lower end 12p. In addition, the insertion pin 12 does not break at the time of insertion into the electric wire or does not cause damage such as a crack, and has the strength to be inclined along the outer surface of the electric wire 20-1 and inserted between the electric wires. .

隣接する差し込みピン１２の前記位置Ｈ１から下端１２ｐまでの隙間寸法は、小径電線では小さくすると共に、大径電線では大きくし、かつ、電線２０に差し込みやすいように、下端に向けて差し込みピン１２の幅を狭くしているため、隣接する差し込みピンの隙間寸法を拡大する。よって、図１（Ｂ）に示すように、下段の端子収容室３Ｄから引き出される電線２０−２は、隣接する差し込みピン１２と密着しない。しかしながら、下段の電線２０−２は上段の電線２０−１の真下に位置するため、上方から垂れ落ちてくる水滴（Ｑ１、Ｑ２）は上段の電線２０−１で受け止められ、下段の電線２０−２に水滴が付着しない。よって、下段の電線２０−２が差し込みピン１２と接触しなくとも問題はない。   The gap dimension from the position H1 to the lower end 12p of the adjacent insertion pin 12 is made smaller for the small-diameter electric wire, larger for the large-diameter electric wire, and easily inserted into the electric wire 20 toward the lower end. Since the width is narrowed, the gap between adjacent insertion pins is enlarged. Therefore, as illustrated in FIG. 1B, the electric wire 20-2 drawn from the lower terminal accommodating chamber 3 </ b> D does not adhere to the adjacent insertion pin 12. However, since the lower wire 20-2 is located immediately below the upper wire 20-1, the water drops (Q1, Q2) dripping from above are received by the upper wire 20-1, and the lower wire 20-. No water droplets adhere to 2. Therefore, there is no problem even if the lower wire 20-2 does not contact the insertion pin 12.

コネクタ１への櫛状防水材１０の取り付けは以下の手順で行う。
まず、図４（Ａ）に示すように、端子２５を端末に圧着接続した電線２０をコネクタ１の上下２段の端子収容室３内にそれぞれ挿入係止する。この時点では、櫛状防水材１０をコネクタ１に取り付けていない。 The comb waterproof material 10 is attached to the connector 1 in the following procedure.
First, as shown in FIG. 4A, the electric wires 20 in which the terminals 25 are crimped and connected to the terminals are inserted and locked in the upper and lower terminal housing chambers 3 of the connector 1. At this time, the comb waterproof material 10 is not attached to the connector 1.

電線２０の端末に接続した端子２５をコネクタ１の各端子収容室３内に挿入し、ランスで所定位置に固定した後に、図４（Ｂ）に示すように、櫛状防水材１０をコネクタハウジング２に上方からコネクタハウジング２の前面２ｂに沿わせて下降させて取り付ける。即ち、櫛状防水材１０の上端連結枠１１を作業員が把持して、差し込みピン１２を下端１２ｐより端子収容室３から引き出される電線２０に上方から差し込んでいく。   After the terminal 25 connected to the terminal of the electric wire 20 is inserted into each terminal accommodating chamber 3 of the connector 1 and fixed in place with a lance, as shown in FIG. 4B, the comb waterproof material 10 is connected to the connector housing. 2 is attached by being lowered along the front surface 2b of the connector housing 2 from above. That is, an operator holds the upper end connection frame 11 of the comb waterproof material 10 and inserts the insertion pin 12 into the electric wire 20 drawn from the terminal accommodating chamber 3 from the lower end 12p from above.

差し込み過程で、差し込みピン１２の一部が上段の電線２０−１と接触すると、接触した差し込みピン１２は電線２０−１で両側に押し広げられ、図１（Ｂ）に示すように、隣接する差し込みピン１２の隙間が広がる方向に傾斜し、電線通し空間Ｃが形成される。この電線通し空間Ｃに下段の端子収容室３Ｄから引き出される下段の電線２０−２を通すことになる。このように、後付けする櫛状防水材１０をコネクタ１から引き出される電線２０に上方から差し込む操作だけで、電線２０を一括かつ同時に櫛状防水材１０の電線通し空間に通すことができる。   When a part of the insertion pin 12 comes into contact with the upper-stage electric wire 20-1 in the insertion process, the contact insertion pin 12 is spread to both sides by the electric wire 20-1, and is adjacent as shown in FIG. The wire insertion space 12 is inclined in the direction in which the gap between the insertion pins 12 is widened, and a wire passing space C is formed. The lower wire 20-2 drawn out from the lower terminal accommodating chamber 3D is passed through the wire passing space C. In this way, the electric wires 20 can be passed through the electric wire passing space of the comb-shaped waterproof material 10 all at once by simply inserting the comb-shaped waterproof material 10 to be retrofitted into the electric wires 20 drawn from the connector 1 from above.

電線２０に差し込みピン１２を差し込んで取り付ける櫛状防水材１０は、差し込みピン１２の間に挟みこむ複数の電線２０により支持され、これら電線２０の端末に接続した端子２５をコネクタハウジング２内に挿入係止して、電線２０をコネクタ１で支持している。よって、これら電線２０で支持される櫛状防水材１０の上端連結枠部１１をコネクタハウジング２の上壁前面２ｂに押し当てた位置で、櫛状防水材１０自体を保持することができる。よって、櫛状防水材１０を接着剤や機械的固定手段で固定することなくコネクタハウジング２に取り付けることができる。
なお、上端連結枠部１１のコネクタハウジング当接面に粘着剤を塗布した剥離紙を取り付けておき、該剥離紙を取り外して、上端連結枠部１１をコネクタハウジングの上壁前面に固着してもよい。 The comb-like waterproof material 10 attached by inserting the insertion pin 12 into the electric wire 20 is supported by a plurality of electric wires 20 sandwiched between the insertion pins 12, and the terminals 25 connected to the ends of these electric wires 20 are inserted into the connector housing 2. The electric wire 20 is supported by the connector 1 by being locked. Therefore, the comb waterproof material 10 itself can be held at a position where the upper end connecting frame portion 11 of the comb waterproof material 10 supported by the electric wires 20 is pressed against the upper surface 2b of the connector housing 2. Therefore, the comb waterproof material 10 can be attached to the connector housing 2 without being fixed with an adhesive or mechanical fixing means.
Note that a release paper coated with an adhesive may be attached to the connector housing contact surface of the upper end connection frame portion 11, and the release paper may be removed to fix the upper end connection frame portion 11 to the front surface of the upper wall of the connector housing. Good.

前記のように、本発明では、コネクタ１の端子収容室３内に電線端末の端子２５を挿入係止後に、該コネクタ１の端子挿入側前面に沿わせてコネクタ１から引き出される電線２０に櫛状防水材１０の差し込みピン１２を差し込んで簡易防水を行っている。この差し込みピン１２を上方から電線２０の間に差し込んで行く過程で、隣接する差し込みピンの間の電線通し空間Ｃに全電線２０を一括して通すことができる。よって、従来のコネクタに先付けされた防水カバーの電線通し穴に電線をそれぞれ挿通する作業が必要がある防水コネクタと比較して電線の通し作業を非常に簡単にでき、作業を短時間で効率よく行うことができる。   As described above, in the present invention, after inserting and locking the terminal 25 of the electric wire terminal into the terminal accommodating chamber 3 of the connector 1, the comb is applied to the electric wire 20 drawn from the connector 1 along the front surface of the terminal insertion side of the connector 1. Simple waterproofing is performed by inserting the insertion pin 12 of the water-proof waterproof material 10. In the process of inserting the insertion pin 12 between the electric wires 20 from above, all the electric wires 20 can be collectively passed through the electric wire passing space C between the adjacent insertion pins. Therefore, compared to conventional waterproof connectors that require the work of inserting the wires into the wire holes of the waterproof cover that is attached to the conventional connector, the work of passing the wires can be made much easier and the work can be done quickly and efficiently. It can be carried out.

また、コネクタの端子収容室３Ｕから引き出された位置の電線２０−１で隣接する差し込みピン１２を押し広げるため、該電線２０−１の外面と差し込みピン１２とは密着する。よって、上方からコネクタ前面に沿って垂れ落ちてくる水滴（Ｑ１、Ｑ２）および電線２０−１の外面を伝ってくる水滴（Ｑ３）を差し込みピン１２で受け止め、水滴（Ｑ）がコネクタ１の端子収容室３内に端子挿入側開口２ｈから浸水するのを防止することができる。   Moreover, in order to spread the adjacent insertion pin 12 with the electric wire 20-1 of the position pulled out from the terminal accommodating chamber 3U of the connector, the outer surface of the electric wire 20-1 and the insertion pin 12 are brought into close contact with each other. Therefore, water drops (Q1, Q2) dripping along the front surface of the connector from above and water drops (Q3) transmitted along the outer surface of the electric wire 20-1 are received by the insertion pin 12, and the water drops (Q) are the terminals of the connector 1. It is possible to prevent water from entering the storage chamber 3 from the terminal insertion side opening 2h.

図５に櫛状防水材１０の差し込みピンの変形例を示す。
上端連結枠部１１の下面に垂設する差し込みピン１２は 上段の電線２０−１と接触する位置Ｈ１までは、直線部１２ｄとして、隣接する差し込みピン１２の間に隙間がないスリットを設け、Ｈ１から下向き傾斜部１２ｅを設け、該下向き傾斜部１２ｅの下部１２ｆは下端１２ｐまで直線状としている。 FIG. 5 shows a modification of the insertion pin of the comb waterproof material 10.
The insertion pin 12 suspended from the lower surface of the upper end connecting frame portion 11 is provided with a slit having no gap between the adjacent insertion pins 12 as a straight portion 12d up to a position H1 in contact with the upper electric wire 20-1, H1 A downward inclined portion 12e is provided, and a lower portion 12f of the downward inclined portion 12e is linear up to the lower end 12p.

該形状とすると、図５（Ｂ）に示すように、コネクタ１に接続する上下段の電線２０−１と２０−２とが同一径の電線であると、下段の電線２０−２も隣接する差し込みピン１２と接触させることができる。よって、電線２０−２の外周面に沿う水滴を差し込みピン１２で受け止めて、端子収容室３に浸入するのを防止できる。   As shown in FIG. 5B, when the upper and lower wires 20-1 and 20-2 connected to the connector 1 have the same diameter, the lower wire 20-2 is adjacent to the connector 20 as shown in FIG. It can be brought into contact with the insertion pin 12. Therefore, it is possible to prevent water drops along the outer peripheral surface of the electric wire 20-2 from being received by the insertion pin 12 and entering the terminal accommodating chamber 3.

図６に第２実施形態を示す。
第２実施形態ではコネクタハウジング２に図６（Ｂ）に示す防水材３０を取り付けている。該防水材３０は前記櫛状防水材１０の上端連結枠部１１の上面に両側に延在する傘部３１を一体的に設けている。傘部３１は円弧形状で上端連結枠部１１から一方側に延在する部分はコネクタハウジング２の上面２ａに搭載する搭載部３１ａとすると共に、他方側はコネクタハウジング２より引き出される電線２の上方に位置させて電線外面への水滴の落下を防止する電線側傘部３１ｂとしている。
傘部３１の電線側傘部３１ｂは他方の搭載部３１ａより下方に湾曲して延在する寸法を大とし、コネクタ１から引き出される電線２０を下向きにガイドしている。
また、搭載部３１ａも緩い円弧状とし、その先端３１ａｐをコネクタハウジングの上面に押し付けるようにしている。 FIG. 6 shows a second embodiment.
In the second embodiment, the waterproof material 30 shown in FIG. 6B is attached to the connector housing 2. The waterproof material 30 is integrally provided with umbrella portions 31 extending on both sides on the upper surface of the upper end connecting frame portion 11 of the comb-shaped waterproof material 10. The umbrella portion 31 has an arc shape, and a portion extending from the upper end connecting frame portion 11 to one side is a mounting portion 31 a mounted on the upper surface 2 a of the connector housing 2, and the other side is above the electric wire 2 drawn out from the connector housing 2. It is set as the electric wire side umbrella part 31b which is located in and prevents the fall of the water drop to the outer surface of an electric wire.
The wire-side umbrella portion 31b of the umbrella portion 31 has a large dimension that curves and extends downward from the other mounting portion 31a, and guides the electric wire 20 drawn out from the connector 1 downward.
Further, the mounting portion 31a is also formed in a loose arc shape, and its tip 31ap is pressed against the upper surface of the connector housing.

前記のように、櫛状防水材１０の上部に傘部３１を設けると、搭載部３１ａをコネクタハウジングの上面２ａに設置するため、防水材３０をより安定した姿勢でコネクタハウジング２に取り付けることができる。また、電線側傘部３１ｂによりコネクタに近接する位置の電線２０に傘をかけているため、上方から水滴が垂れ落ちて電線２０の外面に付着するのを防止できる。かつ、電線側傘部３１ｂによりコネクタハウジング２から引き出される電線２０を下向き方向にガイドして配索できる。これにより、電線２０の外面に付着してコネクタ側へと伝ってくる水滴を、コネクタとの接続位置の直前で自重で落下させてコネクタの防水を図ることができる。   As described above, when the umbrella part 31 is provided on the upper part of the comb-shaped waterproof material 10, the mounting part 31a is installed on the upper surface 2a of the connector housing, so that the waterproof material 30 can be attached to the connector housing 2 in a more stable posture. it can. Moreover, since the electric wire side umbrella part 31b has umbrellad the electric wire 20 at a position close to the connector, it is possible to prevent water droplets from dropping and adhering to the outer surface of the electric wire 20 from above. And the electric wire 20 pulled out from the connector housing 2 by the electric wire side umbrella part 31b can be guided and routed in the downward direction. Thereby, the water droplet which adheres to the outer surface of the electric wire 20 and is transmitted to the connector side can be dropped by its own weight immediately before the connection position with the connector, and the connector can be waterproofed.

櫛状防水材１０の上端連結枠部１１の上面に取り付け穴１１ｈを設け、傘部３１の中央部の下面に突設したピン３１ｊを押し込んで連結している。かつ、傘部３１の電線側傘部３１ｂを下方湾曲部分を大きくし、コネクタから引き出す電線２０が真下向きに配線されるようにガイドしている。
このように、傘部３１と櫛状防水材１０とを別に設けておくと、コネクタに接続する電線２０の配線方向に応じた形状とした傘部３１を選択して用いることができる。 FIG. 7 shows a modification of the second embodiment.
The waterproof material 30 of the modification has the umbrella part 31 and the comb waterproof material 10 as separate bodies.
An attachment hole 11 h is provided on the upper surface of the upper end connection frame portion 11 of the comb waterproof material 10, and a pin 31 j protruding from the lower surface of the central portion of the umbrella portion 31 is pushed in and connected. And the electric wire side umbrella part 31b of the umbrella part 31 enlarges a downward curve part, and is guiding so that the electric wire 20 pulled out from a connector may be wired right below.
Thus, if the umbrella part 31 and the comb-shaped waterproofing material 10 are provided separately, the umbrella part 31 made into the shape according to the wiring direction of the electric wire 20 connected to a connector can be selected and used.

3rd Embodiment is used suitably when connecting the electric wire 20F thicker than the electric wire 20 connected to a connector in 1st Embodiment to a connector.
The shape of the insertion pin 12 that hangs down from the lower surface of the upper end connecting frame portion 11 of the comb-shaped waterproof material 10 is the same as that of the modified example shown in FIG.

前記差し込みピン１２は隣接する差し込みピン１２と対向する側面に羽毛状突片３５を密集させた状態で突設している。該羽毛状突片３５に水滴を吸収する機能を備え、隣接する差し込みピン１２の間の空間に溜まる水滴および電線２０Ｆ−１、２０Ｆ−２の外面に付着する水滴を羽毛状突片３５で吸水し、コネクタの端子収容室３内に浸水しないようにしている。   The insertion pin 12 protrudes in a state in which feather-like protrusions 35 are densely arranged on the side surface facing the adjacent insertion pin 12. The feather-like projecting piece 35 has a function of absorbing water droplets, and the feather-like projecting piece 35 absorbs water drops accumulated in the space between the adjacent insertion pins 12 and water drops attached to the outer surfaces of the electric wires 20F-1 and 20F-2. In addition, water is prevented from entering the terminal housing chamber 3 of the connector.
