Description

本発明は、防水コネクタの内部に生じる膨張空気を開放するための構造に関する。   The present invention relates to a structure for releasing expanded air generated inside a waterproof connector.

下記特許文献１には、防水コネクタの防水栓に関する技術が開示されている。具体的には、防水コネクタの外部温度が急激に変化した際に生じるハウジング内外の圧力差を吸収することができるような防水栓の構造についての技術が開示されている。この防水栓は、端面中央に薄肉状の圧力吸収部が一体的に設けられる構造であって、ハウジング内外の圧力変化に応じて圧力吸収部が膨張収縮作用をするようになっている。   Patent Document 1 listed below discloses a technique related to a waterproof plug of a waterproof connector. Specifically, a technique for a waterproof plug structure that can absorb a pressure difference between the inside and outside of the housing that occurs when the external temperature of the waterproof connector changes rapidly is disclosed. This waterproof plug has a structure in which a thin pressure absorbing portion is integrally provided at the center of an end surface, and the pressure absorbing portion expands and contracts according to a pressure change inside and outside the housing.

防水コネクタが自動車配線用としてエンジンルーム内に設置される場合を考えると、圧力吸収部を有する防水栓を用いることにより、正圧状態及び負圧状態の繰り返し現象が生じて圧力変化があっても、防水栓がコネクタハウジングから脱落してしまうような不具合が防止されるという効果を奏する。
特公昭５７−１６４７４号公報 Considering the case where the waterproof connector is installed in the engine room for automobile wiring, even if there is a pressure change due to the repeated phenomenon of the positive pressure state and negative pressure state by using the waterproof plug having the pressure absorbing part There is an effect that the problem that the waterproof plug falls off the connector housing is prevented.
Japanese Patent Publication No.57-16474

ところで、上記従来技術にあっては、コネクタハウジングの内部に空気を完全に閉じこめた状態で圧力変化に対応するような構造になっている。従って、防水栓に常に圧力が掛かってしまう恐れがあり、防水栓の変形が懸念されるという問題点を有している。また、防水栓に常に圧力が掛かっている状態では、何らかの外力で容易に外れてしまうという問題点も有している。尚、これらの問題点は、防水構造の設計にも影響を来してしまうことになる。   By the way, in the said prior art, it has a structure which respond | corresponds to a pressure change in the state which enclosed air inside the connector housing completely. Therefore, there is a possibility that pressure is always applied to the waterproof plug, and there is a problem that the waterproof plug may be deformed. In addition, when the waterproof plug is always under pressure, there is also a problem that it can be easily removed by some external force. These problems will also affect the design of the waterproof structure.

本発明は、上述した事情に鑑みてなされたもので、防水栓の変形防止や外れ防止を図ることが可能な防水コネクタの膨張空気開放構造を提供することを課題とする。   This invention is made | formed in view of the situation mentioned above, and makes it a subject to provide the expansion | swelling air open | release structure of the waterproof connector which can aim at deformation | transformation prevention and removal prevention of a waterproof stopper.

上記課題を解決するためになされた請求項１記載の本発明の防水コネクタの膨張空気開放構造は、防水コネクタにおける所望の位置の防水栓に、一端がコネクタハウジング内に配置されるとともに他端が前記防水コネクタから離れて存在する被水無き区域に配置され、且つ前記コネクタハウジング内と前記被水無き区域との間の呼吸路を有する構造の線状部材を設けることを特徴としている。   According to a first aspect of the present invention, there is provided an inflating air release structure for a waterproof connector according to the present invention, wherein one end of the waterproof connector is disposed in the connector housing at a desired position and the other end is disposed in the connector housing. A linear member is provided which is disposed in a water-free area existing away from the waterproof connector and has a breathing path between the connector housing and the water-free area.

このような特徴を有する本発明によれば、防水コネクタのコネクタハウジング内において膨張した空気が線状部材を介して大気に開放される。大気に開放される位置は、防水コネクタから離れて存在する被水の無い区域であり、これによって防水コネクタとしての機能は十分に保たれる。コネクタハウジング内の膨張した空気が大気に開放されることにより、防水栓の変形や外れが防止される。   According to the present invention having such a feature, the air expanded in the connector housing of the waterproof connector is released to the atmosphere via the linear member. The position opened to the atmosphere is a water-free area that exists away from the waterproof connector, and thus the function as the waterproof connector is sufficiently maintained. When the expanded air in the connector housing is released to the atmosphere, the waterproof plug is prevented from being deformed or detached.

本発明において、線状部材として電線を用いれば、電線の素線間の微小な隙間により呼吸作用が確保されて大気開放が可能になる。線状部材は、電線若しくは電線と同等の径のチューブで対応することが可能であり、この場合に防水栓は専用のものを用いる必要性が無くなる。すなわち、一般的な防水栓を流用することができるようになる。線状部材として電線を用いる場合には、線状部材が防水コネクタにおいてダミー線のようなものとなる。   In the present invention, when an electric wire is used as the linear member, a breathing action is secured by a minute gap between the wires of the electric wire, and the atmosphere can be released. The linear member can be handled by an electric wire or a tube having a diameter equivalent to that of the electric wire. In this case, it is not necessary to use a dedicated waterproof plug. That is, a general waterproof plug can be used. When an electric wire is used as the linear member, the linear member becomes a dummy wire in the waterproof connector.

請求項２記載の本発明の防水コネクタの膨張空気開放構造は、請求項１に記載の防水コネクタの膨張空気開放構造において、前記所望の位置を、前記コネクタハウジングの空キャビティとすることを特徴としている。   The expansion air release structure of the waterproof connector according to claim 2 of the present invention is characterized in that, in the expansion air release structure of the waterproof connector according to claim 1, the desired position is an empty cavity of the connector housing. Yes.

このような特徴を有する本発明によれば、空キャビティを介してコネクタハウジング内の膨張した空気が大気に開放される。コネクタハウジングや防水栓自体に特別な構造を施さずに線状部材の取り付けが可能になる。   According to the present invention having such a feature, the expanded air in the connector housing is released to the atmosphere through the empty cavity. The linear member can be attached without providing a special structure to the connector housing or the waterproof plug itself.

請求項１に記載された本発明によれば、防水栓の変形や外れを防止することができるという効果を奏する。また、請求項２に記載された本発明によれば、より良い形態の例を提供することができるという効果を奏する。   According to the first aspect of the present invention, there is an effect that the waterproof plug can be prevented from being deformed or detached. Further, according to the present invention described in claim 2, there is an effect that an example of a better form can be provided.

以下、図面を参照しながら説明する。図１は本発明の防水コネクタの膨張空気開放構造の一実施の形態を示す図であり、（ａ）は模式的な全体構成図、（ｂ）は防水コネクタの要部断面図である。   Hereinafter, description will be given with reference to the drawings. 1A and 1B are diagrams showing an embodiment of an inflating air release structure for a waterproof connector according to the present invention. FIG. 1A is a schematic overall configuration diagram, and FIG.

図１において、引用符号１、２は、特に限定するものではないが、アースをするために用いる防水コネクタを示している。防水コネクタ１は、アース部３に直接接続するために設けられている。これに対して防水コネクタ２は、所望の回路４に接続されて、この状態で防水コネクタ１に嵌合し接続がなされるように設けられている。防水コネクタ２は、本発明に係る特徴的な構造を有している。以下、このような防水コネクタ１、２を参照しながら本発明について説明する。   In FIG. 1, reference numerals 1 and 2 indicate a waterproof connector used for grounding although not particularly limited. The waterproof connector 1 is provided for direct connection to the ground part 3. On the other hand, the waterproof connector 2 is provided so as to be connected to a desired circuit 4 and to be fitted and connected to the waterproof connector 1 in this state. The waterproof connector 2 has a characteristic structure according to the present invention. Hereinafter, the present invention will be described with reference to such waterproof connectors 1 and 2.

防水コネクタ１は、コネクタハウジング５と、このコネクタハウジング５に収容される雄端子６と、防水コネクタ２に密着するシール部材７とを備えて構成されている。コネクタハウジング５には、雄端子６に対する端子収容用のキャビティ（図示省略）と、防水コネクタ２に対する嵌合用の空間を形成するための嵌合部８とが形成されている。雄端子６は、アース部３に接続されている。雄端子６は、この電気接触部が防水コネクタ２と電気的に接続されるように配置固定されている。シール部材７は、嵌合部８に取り付けられている。シール部材７は、環状の部材となるように形成されている。   The waterproof connector 1 includes a connector housing 5, a male terminal 6 accommodated in the connector housing 5, and a seal member 7 that is in close contact with the waterproof connector 2. The connector housing 5 is formed with a terminal accommodating cavity (not shown) for the male terminal 6 and a fitting portion 8 for forming a fitting space for the waterproof connector 2. The male terminal 6 is connected to the ground part 3. The male terminal 6 is arranged and fixed so that the electrical contact portion is electrically connected to the waterproof connector 2. The seal member 7 is attached to the fitting portion 8. The seal member 7 is formed to be an annular member.

防水コネクタ２は、コネクタハウジング９と、このコネクタハウジング９に収容される雌端子１０と、防水栓１１、１２と、ダミー線（線状部材）１３とを備えて構成されている。コネクタハウジング９には、雌端子１０に対する端子収容用のキャビティ１４が上下二段に形成されている。上段のキャビティ１４には、雌端子１０が収容固定されている。これに対して下段のキャビティ１４には、雌端子１０が収容されず空のキャビティ、すなわち空キャビティとなっている。コネクタハウジング９は、この外面に防水コネクタ１のシール部材７が密着して水密及び気密構造を形成するようになっている。   The waterproof connector 2 includes a connector housing 9, a female terminal 10 accommodated in the connector housing 9, waterproof plugs 11 and 12, and a dummy wire (linear member) 13. In the connector housing 9, a terminal accommodating cavity 14 for the female terminal 10 is formed in two upper and lower stages. The female terminal 10 is accommodated and fixed in the upper cavity 14. On the other hand, the lower cavity 14 does not receive the female terminal 10 and is an empty cavity, that is, an empty cavity. The connector housing 9 is configured such that a sealing member 7 of the waterproof connector 1 is in close contact with the outer surface to form a watertight and airtight structure.

雌端子１０は、既知の電線１５の端末に設けられている。雌端子１０は、この電気接触部が防水コネクタ１の雄端子６と電気的に接続されるように配置固定されている。電線１５には、予めゴム製の防水栓１１が挿通されている。防水栓１１は、電線１５の端末に雌端子１０を接続した後に、この雌端子１０の位置まで移動させて取り付けがなされるようになっている。防水栓１１は、雌端子１０の取り付け収容の際にキャビティ１４に挿入されて、このキャビティ１４に密着し、水密及び気密構造を形成するようになっている。電線１５は、回路４に接続されている（一例であるものとする。電線１５は、例えばワイヤハーネスから分岐されたものであってもよいものとする）。   The female terminal 10 is provided at the end of a known electric wire 15. The female terminal 10 is arranged and fixed so that the electrical contact portion is electrically connected to the male terminal 6 of the waterproof connector 1. A rubber waterproof plug 11 is inserted into the electric wire 15 in advance. After the female terminal 10 is connected to the end of the electric wire 15, the waterproof plug 11 is moved to the position of the female terminal 10 and attached. The waterproof plug 11 is inserted into the cavity 14 when the female terminal 10 is mounted and accommodated, and is in close contact with the cavity 14 to form a watertight and airtight structure. The electric wire 15 is connected to the circuit 4 (assumed to be an example. The electric wire 15 may be branched from a wire harness, for example).

防水栓１２は、電線１５に挿通された防水栓１１と同じものであって、空キャビティとなる下段のキャビティ１４に挿入されている。防水栓１２は、空のキャビティ１４に密着して水密及び気密構造を形成するようになっている。このような防水栓１２は、予めダミー線（線状部材）１３に挿通されて、この後に空のキャビティ１４に挿入されるようになっている。   The waterproof plug 12 is the same as the waterproof plug 11 inserted through the electric wire 15, and is inserted into the lower cavity 14 serving as an empty cavity. The waterproof plug 12 is in close contact with the empty cavity 14 to form a watertight and airtight structure. Such a waterproof plug 12 is inserted through a dummy wire (linear member) 13 in advance and then inserted into an empty cavity 14.

ダミー線１３は、この一端が空のキャビティ１４内に配置されるとともに、他端が防水コネクタ２から離れて存在する被水無き区域１６に配置されている（防水コネクタ１、２は防水を必要とする区域１７に設置されている）。ダミー線１３は、被水無き区域１６までの配索に必要な長さを有している。ダミー線１３は、本形態において、電線１５と同じ既知の電線からなるものであって、素線間の微小な隙間により呼吸路（図示省略）が形成されて呼吸作用が確保されるようになっている（空のキャビティ１４内と被水無き区域１６との間において、呼吸路を介して呼吸作用が十分に確保できない場合には、電線に変えてチューブでダミー線１３を形成してもよいものとする）。   One end of the dummy wire 13 is disposed in an empty cavity 14 and the other end is disposed in a water-free area 16 that is separated from the waterproof connector 2 (the waterproof connectors 1 and 2 require waterproofing). It is installed in area 17). The dummy line 13 has a length necessary for wiring up to the area 16 without water. In this embodiment, the dummy wire 13 is made of the same known wire as the wire 15, and a breathing path (not shown) is formed by a minute gap between the strands so as to ensure a breathing action. (If the respiratory action cannot be sufficiently secured between the empty cavity 14 and the unwatered area 16 via the respiratory path, the dummy wire 13 may be formed of a tube instead of an electric wire. Suppose).

上記構成において、防水コネクタ１及び２を嵌合させると、シール部材７及び防水栓１１、１２の存在によって、防水コネクタ１及び２の内部に空気が閉じこめられる。そして、この状態のままでエンジンルーム内に防水コネクタ１及び２が設置されると、正圧状態及び負圧状態の繰り返し現象が生じた場合に、圧力変化を受けてしまうことになる。しかしながら本発明によれば、防水コネクタ１及び２の内部において膨張した空気は、この逃げ場としてダミー線１３の呼吸路（図示省略）を伝い、被水無き区域１６においてダミー線１３の他端から大気に放出される。従って、防水栓１１、１２等の変形防止や外れ防止を図ることができる。   In the above configuration, when the waterproof connectors 1 and 2 are fitted, air is trapped inside the waterproof connectors 1 and 2 due to the presence of the seal member 7 and the waterproof plugs 11 and 12. If the waterproof connectors 1 and 2 are installed in the engine room in this state, a pressure change is received when a repeated phenomenon of a positive pressure state and a negative pressure state occurs. However, according to the present invention, the air inflated inside the waterproof connectors 1 and 2 travels along the breathing path (not shown) of the dummy wire 13 as a refuge, and the atmosphere from the other end of the dummy wire 13 in the unwatered area 16 To be released. Accordingly, it is possible to prevent the waterproof plugs 11 and 12 from being deformed or prevented from coming off.

本発明によれば、防水コネクタ１、２の内部に生じる膨張空気を開放するための構造であり、防水栓１１、１２等の変形防止や外れ防止を図ることで、従来よりもコネクタとしての機能を高めたり維持したりすることができるという効果を奏する。   According to the present invention, it is a structure for releasing the expansion air generated inside the waterproof connectors 1 and 2, and prevents the deformation of the waterproof plugs 11, 12, etc., and prevents them from coming off, thereby functioning as a connector more than conventional ones. There is an effect that can be increased or maintained.

その他、本発明は本発明の主旨を変えない範囲で種々変更実施可能なことは勿論である。   In addition, it goes without saying that the present invention can be variously modified without departing from the spirit of the present invention.
