Description

本発明は、コネクタの成形方法であって、例えば各種機器の隔壁に貫装されて当該機器内外の配線を接続するコネクタに関するものである。   The present invention relates to a method for forming a connector, for example, a connector that is inserted in a partition wall of various devices and connects wiring inside and outside the device.

例えば、自動車のエンジンルーム，オートマチックトランスミッション，燃料タンク等の各種機器の隔壁に貫装（コネクタ用の貫通孔に貫装）されて当該機器内外の配線を接続するコネクタとしては、防水性，防油性等のシール性を有するものが知られている。このようなシール構造のコネクタの一例としては、そのコネクタを構成するコネクタハウジングや中継端子等が、型成形（インサート成形等）により一体化されたものが挙げられる。コネクタハウジングは、筒状側壁の内部空間における機器内側と機器外側とが当該内部空間の中央部に形成された仕切り壁により仕切られたものであって、その筒状側壁の外周面にシール部材（筒状側壁の周方向に延在する環状のシール部材を）を設けて機器隔壁とのシール性を付与したものが知られている（例えば特許文献１〜３）。   For example, as a connector that penetrates through the partition walls of various devices such as automobile engine rooms, automatic transmissions, fuel tanks, etc. (penetrating through the connector through holes) and connects wiring inside and outside the device, it is waterproof and oilproof. Those having a sealing property such as the above are known. As an example of the connector having such a seal structure, a connector housing, a relay terminal and the like constituting the connector are integrated by die molding (insert molding or the like). The connector housing is a device in which the inside of the device and the outside of the device in the internal space of the cylindrical side wall are partitioned by a partition wall formed in the central portion of the internal space, and a seal member ( An annular seal member extending in the circumferential direction of a cylindrical side wall is provided to provide a sealing property with an apparatus partition wall (for example, Patent Documents 1 to 3).

型成形においては、複数の型部材を組み合わせた成形型（金型）が適用されるが、その適用される型の種類（型開き方向）に応じて、所謂パーティングラインが筒状側壁等に形成されてしまう。このパーティングラインが筒状側壁の軸心方向に延在するように形成されると、前記シール部材がパーティングラインの外周側と交差し段差を生じて取り付けられ、その交差した箇所において筒状側壁の外周側とシール部材との間のシール面に隙間が形成されるため、コネクタを機器の隔壁の貫通孔に貫装させた際（以下、貫装時と称する）に所望のシール性が得られなくなる虞がある。このため、パーティングラインとシール部材とが交差しないように型成形、例えば筒状側壁の外周側を成形する型部材として、その筒状側壁の軸心方向に型開きするものを適用することが考えられている（例えば特許文献１，４）。   In mold molding, a mold (mold) in which a plurality of mold members are combined is applied. Depending on the type of mold (mold opening direction), a so-called parting line is formed on the cylindrical side wall or the like. Will be formed. When the parting line is formed so as to extend in the axial direction of the cylindrical side wall, the sealing member is attached to the outer peripheral side of the parting line so as to form a step, and the cylindrical part is formed at the intersected portion. Since a gap is formed on the sealing surface between the outer peripheral side of the side wall and the sealing member, a desired sealing property is obtained when the connector is inserted into the through hole of the partition wall of the device (hereinafter referred to as “at the time of installation”). There is a risk that it will not be obtained. For this reason, it is possible to apply mold forming so that the parting line and the seal member do not intersect, for example, as a mold member for forming the outer peripheral side of the cylindrical side wall, which opens the mold in the axial direction of the cylindrical side wall. It is considered (for example, Patent Documents 1 and 4).

しかしながら、筒状側壁の外周側においてシール部材を嵌合（外嵌）させるための環状溝を形成する場合（例えば特許文献３）、その環状溝に対応する型部材として、前記のように筒状側壁の軸心方向に型開きする型部材を適用することはできない。したがって、例えば筒状側壁の径方向に型開きする型部材等（筒状側壁の周方向に分割された型）を適用することになるが、図５Ａ〜Ｃに示すコネクタのように、筒状側壁２１の軸心方向に延在するパーティングライン２２が環状溝２３内に形成（環状溝の延在方向と交差するように形成）されてしまうため、例えば型成形後にパーティングライン２２を研磨等により除去する必要があった。   However, when an annular groove for fitting (external fitting) a seal member is formed on the outer peripheral side of the cylindrical side wall (for example, Patent Document 3), as a mold member corresponding to the annular groove, a cylindrical shape as described above. A mold member that opens in the axial direction of the side wall cannot be applied. Therefore, for example, a mold member or the like that opens in the radial direction of the cylindrical side wall (a mold divided in the circumferential direction of the cylindrical side wall) is applied. However, like the connector shown in FIGS. Since the parting line 22 extending in the axial direction of the side wall 21 is formed in the annular groove 23 (formed so as to intersect the extending direction of the annular groove), for example, the parting line 22 is polished after molding. It was necessary to remove by such as.

本願発明者は、前記のような背景技術等に伴って、コネクタの成形方法においては、以下に示す課題があることに着目した。すなわち、コネクタハウジングの筒状側壁の周方向に延在する環状溝にシール部材が設けられたコネクタにおいて、パーティングラインに起因した隙間が形成されないように抑制し、所望のシール性が得られるようにすることが考えられる。   The inventor of the present application has paid attention to the following problems in the method for forming a connector in accordance with the background art as described above. That is, in the connector in which the seal member is provided in the annular groove extending in the circumferential direction of the cylindrical side wall of the connector housing, the gap due to the parting line is suppressed so that a desired sealing property can be obtained. Can be considered.

この発明に係るコネクタの成形方法は、前記の課題を解決できる創作であり、具体的に、この発明のコネクタの成形方法の一態様は、機器隔壁の貫通孔に貫装されて当該機器の内外の配線を接続するコネクタを型成形する方法であって、前記貫通孔に貫装される筒状側壁を有し、その筒状側壁の内部空間における機器内側と機器外側とが当該内部空間の中央部に形成される仕切り壁により仕切られ、前記筒状側壁の外周側において当該筒状側壁の周方向に延在する環状溝が形成されるコネクタハウジング、を成形する成形型内に、前記筒状側壁の軸心方向に沿って延在する端子であって仕切り壁を貫通し両端がそれぞれ前記内部空間における機器内側，機器外側に突出する少なくとも一つの中継端子を配置して型成形することにより一次成形体を形成した後、前記一次成形体に対し、前記環状溝内を溝埋めする部材であって当該部材の外周側が環状溝から突出する環状シール部材を、型成形することを特徴とする。   The connector molding method according to the present invention is a creation that can solve the above-described problems. Specifically, one aspect of the connector molding method according to the present invention is inserted through the through-hole of the device partition wall, and the inside and outside of the device. A connector for connecting the wiring of the apparatus has a cylindrical side wall penetrating the through hole, and the inside of the device and the outside of the device in the internal space of the cylindrical side wall are the center of the internal space. In the molding die for molding a connector housing, which is partitioned by a partition wall formed in a portion and formed with an annular groove extending in the circumferential direction of the cylindrical side wall on the outer peripheral side of the cylindrical side wall A terminal that extends along the axial direction of the side wall and is formed by placing and molding at least one relay terminal penetrating the partition wall and projecting at both ends inside and outside the device in the internal space, respectively. Molding After forming, said to primary molded body, the outer peripheral side of the member in said annular groove a member that fills grooves the annular sealing member protruding from the annular groove, characterized in that molding.

また、前記一次成形体に対し、前記仕切り壁における機器外側の表面に積層される部材であって前記中継端子における機器外側に突出した部位が貫通する層状シール部材を、環状シール部材と同一工程で型成形することとしても良い。さらに、前記環状溝は、前記筒状側壁の外周側で前記貫通孔内壁と対向する位置に形成されるものとしても良い。   In addition, a layered seal member that is a member laminated on the outer surface of the partition wall on the primary molded body and through which a portion projecting to the outer side of the relay terminal passes is formed in the same process as the annular seal member. It may be molded. Furthermore, the said annular groove is good also as what is formed in the position facing the said through-hole inner wall in the outer peripheral side of the said cylindrical side wall.

本発明に係るコネクタおよびコネクタの成形方法によれば、パーティングラインに起因する隙間が形成されないように抑制でき、所望のシール性が得られ易くなる。   According to the connector and the method for forming a connector according to the present invention, it is possible to suppress a gap due to the parting line from being formed, and a desired sealing property can be easily obtained.

本発明の実施形態に係るコネクタの成形方法は、筒状側壁が機器隔壁の貫通孔に貫装されるコネクタハウジングにおいて、単に筒状側壁の外周側で周方向に環状溝を形成して当該環状溝にシール部材を嵌合させるのではなく、まず、環状溝を有する一次成形体を形成した後、その前記一次成形体に対し、環状溝を溝埋めして環状シール部材を型成形するものである。   In the connector molding method according to the embodiment of the present invention, in the connector housing in which the cylindrical side wall is inserted into the through hole of the device partition wall, an annular groove is simply formed in the circumferential direction on the outer peripheral side of the cylindrical side wall. Instead of fitting a seal member into the groove, first, after forming a primary molded body having an annular groove, the annular groove is filled in the primary molded body to mold the annular seal member. is there.

このようなシール部材の型成形によれば、その型成形時に環状シール部材のシール材料を、一次成形体の環状溝内に対して当該環状溝を溝埋めしながら充填（環状溝内に隙間が形成されないように充填）することができる。そして、充填されたシール材料を固化して形成された環状シール部材においては、その環状溝内に位置する部位が当該環状溝と同じ形状となるため、例えば環状溝内にパーティングラインが形成されていたとしても、パーティングラインに起因する隙間（環状シール部材とパーティングラインとの間に形成され得る隙間）が形成されないように抑制できる。したがって、環状シール部材と環状溝とが互いに十分密着し、所望のシール性が得られ易くなる。   According to such molding of the seal member, the sealing material of the annular seal member is filled while filling the annular groove of the primary molded body while filling the annular groove in the mold (there is a gap in the annular groove). Filling) so that it is not formed. In the annular seal member formed by solidifying the filled sealing material, the part located in the annular groove has the same shape as the annular groove, so that, for example, a parting line is formed in the annular groove. Even if it exists, it can suppress that the clearance gap (gap | interval which can be formed between an annular sealing member and a parting line) resulting from a parting line is not formed. Therefore, the annular seal member and the annular groove are in close contact with each other, and a desired sealing property is easily obtained.

また、前記環状シール部材は環状溝と一体化しているため、貫装時の位置ズレが抑制される。例えば、単に筒状側壁の外周側にシール部材が取り付けられたコネクタにおいて、貫装時にシール部材が機器隔壁の貫通孔内壁と対向する位置までコネクタを貫装させる場合、当該シール部材が位置ズレを起こし易くなるが、本実施形態のように環状溝と一体化された環状シール部材によれば、前記のような位置ズレを抑制しながら、その環状シール部材（環状溝から突出した部位）を貫通孔内壁面に圧接させることが可能となる。   Moreover, since the said annular seal member is integrated with the annular groove, the position shift at the time of penetration is suppressed. For example, in a connector in which a sealing member is simply attached to the outer peripheral side of a cylindrical side wall, when the sealing member is inserted to a position facing the inner wall of the through hole of the device partition wall at the time of insertion, the sealing member is displaced. Although it is easy to cause, according to the annular seal member integrated with the annular groove as in the present embodiment, the annular seal member (part protruding from the annular groove) penetrates while suppressing the positional deviation as described above. It is possible to press the inner wall surface of the hole.

前記のように環状シール部材を型成形する他に、一次成形体の所望の箇所にシール部材を型成形しても良い。例えば、環状シール部材を型成形する工程において、一次成形体の仕切り壁の機器外側の表面をシール材料で被覆（例えば筒状側壁の機器外側開口の方向から注入）し固化することにより、中継端子における機器内側に突出した部位が貫通するように設けられる層状シール部材を、型成形することが挙げられる。このような層状シール部材によれば、中継端子と仕切り壁との接合面に形成され得る隙間により機器内外が連通しないように、シールすることが可能となる。   In addition to molding the annular seal member as described above, the seal member may be molded at a desired location of the primary molded body. For example, in the step of molding the annular seal member, the device outer surface of the partition wall of the primary molded body is coated with a sealing material (for example, injected from the direction of the device outer opening of the cylindrical side wall) and solidified, thereby forming the relay terminal The layered sealing member provided so that the site | part which protruded in the apparatus inside in may penetrate may be mentioned. According to such a layered sealing member, it is possible to seal the device so that the inside and outside of the device do not communicate with each other by a gap that can be formed on the joint surface between the relay terminal and the partition wall.

コネクタハウジングは、目的とする機器の貫通孔に貫装されて機器内外の配線を接続できるものであれば、種々の形態のものを適用することができる。例えば筒状側壁は、横断面形状が真円状に限定されるものではなく、機器の貫通孔や配線の形状等に応じて設計されるものである。また、筒状側壁の外周側から当該筒状側壁の径方向に突出した鍔状のフランジ部が形成されたものの場合には、そのフランジ部を単に目的とする機器の隔壁にコネクタを固定（例えば螺子締め等により固定）するために利用できるだけでなく、貫装時にコネクタを機器内側に対して埋め込み過ぎないように抑制するストッパーとして機能させることが可能となる。仕切り壁においては、筒状側壁の内部空間における機器内側と機器外側とを仕切り当該仕切り壁自体に中継端子が貫通されるものであり、機器内外の配線の接続を妨げない形状であれば良い。なお、前記の層状シール部材を型成形する場合も、前述のように配線の接続を妨げない形状にすることが考えられる。   The connector housing can be applied in various forms as long as it can be inserted into the through hole of the target device and connect the wiring inside and outside the device. For example, the cylindrical side wall is not limited to a perfect circular cross-sectional shape, and is designed according to the shape of the through-hole or wiring of the device. In the case where a flange-like flange portion protruding in the radial direction of the cylindrical side wall is formed from the outer peripheral side of the cylindrical side wall, the flange portion is simply fixed to the partition wall of the target device (for example, In addition to being used for fixing by screwing or the like, it is possible to function as a stopper that suppresses the connector from being embedded too much into the inside of the device during penetration. The partition wall may be any shape that partitions the inside of the device and the outside of the device in the internal space of the cylindrical side wall so that the relay terminal penetrates the partition wall itself and does not hinder the connection of wiring inside and outside the device. Even when the layered sealing member is molded, it is conceivable to have a shape that does not hinder the connection of the wiring as described above.

環状溝は、コネクタの貫装時に貫通孔内壁と対向して位置するように形成することが挙げられるが、前記のようにフランジ部が形成されている場合には、そのフランジ部よりも機器内側の筒状側壁に形成することになる。例えば、貫装時に貫通孔の開口部の縁部に近接する位置（例えば特許文献１の図１に示すシールリングが嵌合されている位置）に対して環状溝を形成した場合であっても、その環状溝に環状シール部材が型成形された状態で当該貫装時に機器内外をシールできれば良い。   The annular groove may be formed so as to be opposed to the inner wall of the through hole when the connector is inserted. When the flange portion is formed as described above, the annular groove is inside the device. It forms in the cylindrical side wall. For example, even when an annular groove is formed at a position close to the edge of the opening of the through hole (for example, a position where the seal ring shown in FIG. 1 of Patent Document 1 is fitted) at the time of penetration. As long as the annular seal member is molded in the annular groove, the inside and outside of the device can be sealed at the time of penetration.

前記のコネクタハウジング，中継端子，環状シール部材，層状シール部材に適用する材料においては、例えばコネクタの分野で利用されているものであれば特に限定されないが、目的とする機器に応じた特性（絶縁性，防水性，耐候性，耐腐食性，導電性，耐衝撃性等）を付与できる材料であって、それぞれ型成形により一体化されるものが挙げられる。その具体例として、コネクタハウジングには熱硬化性樹脂等の絶縁性材料を適用したり、中継端子には銅等の導電性材料を適用することが挙げられる。環状シール部材，層状シール部材においては、シリコーンゴム，アクリルゴム，ウレタンゴム等の弾性材料を適用することが挙げられ、環状シール部材においては、機器の隔壁側（例えば貫通孔内壁）と接する箇所（外周側）をリップ状となるように成形してシール性を高めた形状にすることも考えられる。また、前記の環状シール部材，積層シール部材の各種シール部材を型成形時に形成することにより、コネクタ成形の工程数の削減（例えばシール部材を嵌合する工程の削減）を図ることが可能となる。   The material applied to the connector housing, the relay terminal, the annular seal member, and the layered seal member is not particularly limited as long as it is used in the connector field, for example. Material, water resistance, weather resistance, corrosion resistance, conductivity, impact resistance, etc.), which can be integrated by molding. Specific examples thereof include applying an insulating material such as a thermosetting resin to the connector housing, and applying a conductive material such as copper to the relay terminal. In the annular seal member and the laminar seal member, it is possible to apply an elastic material such as silicone rubber, acrylic rubber, urethane rubber, etc., and in the annular seal member, the portion in contact with the partition wall side (for example, the inner wall of the through hole) ( It is also conceivable that the outer peripheral side) is shaped so as to have a lip shape so that the sealing performance is improved. Further, by forming the various seal members of the annular seal member and the laminated seal member at the time of mold forming, it becomes possible to reduce the number of connector forming steps (for example, reduction of the step of fitting the seal member). .

＜実施例＞
以下、本実施形態に係るコネクタの成形方法の一例を図面に基づいて説明する。なお、図５に示すものと同様のものには、同一符号等を用いて詳細な説明を省略する。 <Example>
Hereinafter, an example of a method for forming a connector according to the present embodiment will be described with reference to the drawings. Note that the same components as those shown in FIG.

まず、図１に示すように、コネクタハウジング２に対し中継端子３が型成形により一体化された一次成形体１１を形成する。コネクタハウジング２は、筒状側壁２１を有するものであって、その筒状側壁２１の内部空間の中央部には、その内部空間を横断する方向に延在した仕切り壁２４が形成されている。この仕切り壁２４により、前記の内部空間における機器内側に位置する空間部２５と機器外側に位置する空間部２６とが、互いに分離して形成されている。符号２７は、筒状側壁２１の外周側の中央部において当該筒状側壁２１の径方向に突出した鍔状のフランジ部を示すものである。筒状側壁２１の外周側でフランジ部２７よりも機器内側には、横断面凹字状の環状溝２３が、当該筒状側壁２１の周方向に沿って延設されている。   First, as shown in FIG. 1, a primary molded body 11 in which the relay terminals 3 are integrated with the connector housing 2 by molding is formed. The connector housing 2 has a cylindrical side wall 21, and a partition wall 24 extending in a direction crossing the internal space is formed at the center of the internal space of the cylindrical side wall 21. With this partition wall 24, a space portion 25 located inside the device and a space portion 26 located outside the device in the internal space are formed separately from each other. Reference numeral 27 denotes a flange-like flange portion protruding in the radial direction of the cylindrical side wall 21 at the central portion on the outer peripheral side of the cylindrical side wall 21. An annular groove 23 having a concave cross section is extended along the circumferential direction of the cylindrical side wall 21 on the outer peripheral side of the cylindrical side wall 21 and inside the device from the flange portion 27.

中継端子３は、目的とする機器内外の配線を電気的に中継するピン状の端子であって、前記仕切り壁２４を貫通して筒状側壁２１の軸心方向に沿って延在するように複数個設けられ、両端がそれぞれ仕切り壁２４から前記空間部２５，２６に突出している。   The relay terminal 3 is a pin-like terminal that electrically relays the wiring inside and outside the target device, and extends along the axial direction of the cylindrical side wall 21 through the partition wall 24. A plurality of them are provided, and both ends protrude from the partition wall 24 into the space portions 25 and 26, respectively.

一次成形体１１は、例えば、筒状側壁２１の外周側を成形する型部材として当該筒状側壁２１の径方向に型開きする型部材を適用した金型（図示省略）内に、インサート成形部材である中継端子３を充填してから、コネクタハウジング２の材料（熱硬化性樹脂等）を注入し固化することにより、図１に示すように中継端子３をコネクタハウジング２の所定位置に一体化させて形成することができる。   The primary molded body 11 is, for example, an insert molded member in a mold (not shown) in which a mold member that opens in the radial direction of the cylindrical side wall 21 is applied as a mold member that molds the outer peripheral side of the cylindrical side wall 21. After filling the relay terminal 3, the material of the connector housing 2 (thermosetting resin or the like) is injected and solidified to integrate the relay terminal 3 at a predetermined position of the connector housing 2 as shown in FIG. Can be formed.

次に、図２に示すように、一次成形体１１の環状溝２３を溝埋めして形成される環状シール部材５と、仕切り壁における空間部２６側の表面に対して積層される層状シール部材４と、を型成形により形成（一体化）して二次成形体１２を得る。環状シール部材５は外周側の部位５１が環状溝２３から突出するように形成され、層状シール部材４は中継端子３における空間部２６側に突出した部位が貫通するように形成される。   Next, as shown in FIG. 2, an annular seal member 5 formed by filling the annular groove 23 of the primary molded body 11, and a layered seal member laminated on the surface of the partition wall on the space portion 26 side. 4 are formed (integrated) by molding to obtain a secondary molded body 12. The annular seal member 5 is formed such that a portion 51 on the outer peripheral side protrudes from the annular groove 23, and the layered seal member 4 is formed so that a portion protruding toward the space 26 in the relay terminal 3 penetrates.

二次成形体１２の型成形には、一次成形体１１と同様の金型であって、環状シール部材５の外周側の部位５１を形成するためのキャビティ（材料が注入される空洞）を有し筒状側壁２１の軸心方向に型開きする型部材や、筒状側壁２１内の空間部２６側に挿入した際に中継端子３（突出した中継端子）が嵌入する嵌入孔を持つ部材であって当該挿入時に仕切り壁２４との間に所定厚さのキャビティを形成する型部材など、を備えた金型（図示省略）が用いられる。そして、この金型内に一次成形体１１が充填された状態で、環状シール部材５，層状シール部材４の材料（例えばシリコーンゴム，アクリルゴム，ウレタンゴム等の弾性材料）を注入し固化することにより、図２に示すように一次成形体１１の所定位置に環状シール部材５，層状シール部材４を一体化させて、二次成形体１２を形成することができる。   The mold of the secondary molded body 12 is a mold similar to the primary molded body 11 and has a cavity (a cavity into which material is injected) for forming the outer peripheral portion 51 of the annular seal member 5. A mold member that opens in the axial direction of the cylindrical side wall 21 or a member having a fitting hole into which the relay terminal 3 (protruding relay terminal) is fitted when inserted into the space 26 side in the cylindrical side wall 21. A mold (not shown) including a mold member that forms a cavity having a predetermined thickness between the partition wall 24 and the partition wall 24 at the time of insertion is used. Then, the material of the annular seal member 5 and the layered seal member 4 (for example, an elastic material such as silicone rubber, acrylic rubber, urethane rubber) is injected and solidified in a state where the primary molded body 11 is filled in the mold. Thus, as shown in FIG. 2, the secondary molded body 12 can be formed by integrating the annular seal member 5 and the layered seal member 4 at a predetermined position of the primary molded body 11.

以上示した型成形により一次成形体１１，二次成形体１２を順次形成して得たコネクタによれば、図３に示すように、たとえ環状溝２３内のパーティングライン２２により微小な段差２２ａが形成されていたとしても、環状シール部材５の型成形時に、段差２２ａを埋めるようにシール部材が環状溝２３に充填（溝埋め）され、その充填されたシール材料を固化して形成された環状シール部材における環状溝内に位置する部位は、その環状溝と同じ形状であって段差２２ａを反映した形状となる。このため、環状シール部材５と環状溝２３との間に隙間（例えば段差２２ａに起因する隙間）が形成されることはなく、互いに十分密着する。   According to the connector obtained by sequentially forming the primary molded body 11 and the secondary molded body 12 by the above-described mold forming, as shown in FIG. 3, a minute step 22a is formed by the parting line 22 in the annular groove 23. Even when the annular sealing member 5 is formed, the sealing member is filled (groove filled) in the annular groove 23 so as to fill the step 22a when the annular sealing member 5 is molded, and the filled sealing material is solidified. The part located in the annular groove in the annular seal member has the same shape as the annular groove and a shape reflecting the step 22a. For this reason, a gap (for example, a gap due to the step 22a) is not formed between the annular seal member 5 and the annular groove 23, and they are sufficiently in close contact with each other.

このように環状シール部材５が形成されたコネクタ（図４中の符号１０；所謂コネクタアッシー）においては、図４に示すように、機器の隔壁６０に穿設された貫通孔６に対して貫装して用いられ、空間部２５，２６に対して機器内外の各配線（図示省略）をそれぞれ嵌装し、中継端子３を介して各配線を互いに導通させる。この貫装時において、環状溝２３が貫通孔６の内壁面６１と対向して位置し、その内壁面６１に対してシール部材５が圧接した状態となり、機器内外のシール性が保持される。隔壁６０の機器外側面６２に係合されるフランジ部２７は、例えば螺子等の締め付け手段（図示省略）を用いて固定しても良い。   In the connector having the annular seal member 5 thus formed (reference numeral 10 in FIG. 4; so-called connector assembly), as shown in FIG. 4, it penetrates the through-hole 6 formed in the partition wall 60 of the device. Each wiring (not shown) inside and outside the device is fitted into the space portions 25 and 26, and the respective wirings are connected to each other via the relay terminal 3. At the time of this penetration, the annular groove 23 is positioned facing the inner wall surface 61 of the through hole 6, and the seal member 5 is in pressure contact with the inner wall surface 61, and the sealing performance inside and outside the device is maintained. The flange portion 27 engaged with the device outer surface 62 of the partition wall 60 may be fixed using a fastening means (not shown) such as a screw.
