Description

本発明は、コネクタハウジング内に充填樹脂が充填されて防液される防液コネクタに関する。   The present invention relates to a liquid-proof connector that is filled with a filling resin in a connector housing and is liquid-proof.

従来、油等の液体が収容されたケース等に取りつけられ、ケース内の液体が外部にもれないようにして相手端子との接続を可能とするコネクタとして防液性を有するコネクタハウジング内に端子が保持収容される防液コネクタが用いられる。例えば、特許文献１には、車両用自動変速機ケースに装着されて、車両用自動変速機ケース内の電気部品と外部の電子コントロールユニットとの電気接続に用いられる防液コネクタが提案されている。   Conventionally, a terminal in a connector housing having a liquid-proof property is attached as a connector that is attached to a case or the like in which a liquid such as oil is accommodated, and that can be connected to a mating terminal so that the liquid in the case is not exposed to the outside. A liquid-proof connector that holds and accommodates is used. For example, Patent Document 1 proposes a liquid-proof connector that is attached to a vehicle automatic transmission case and is used for electrical connection between an electrical component in the vehicle automatic transmission case and an external electronic control unit. .

この特許文献１に記載された防液コネクタでは、充填樹脂が端子と電線との接続部分を覆うようにしてコネクタハウジング内に充填されることによって、防液性能が向上され、車輌用自動変速機ケース内の油がコネクタハウジングを介して外部に漏れないようになっている。   In the liquid-proof connector described in Patent Document 1, the liquid-proof performance is improved by filling the connector housing with the filling resin so as to cover the connection portion between the terminal and the electric wire, so that the vehicle automatic transmission is improved. Oil in the case is prevented from leaking outside through the connector housing.

特開２００２−２７０２８３号公報JP 2002-270283 A

ところで、このような防液コネクタのコネクタハウジングには、図１１に示すように、相手コネクタが嵌入される相手コネクタ嵌入部１２０と、端子１０が端子ホルダ１３０を介して内部に保持され、相手コネクタ嵌入部１２０が連通される端子挿入方向奥側位置１１１から端子１０の挿入口１１０ａに向けて端子１０の挿入方向Ｄに直交する断面が所定の大きさに拡大される断面拡大領域部１１２が形成されてなる端子収容部１１０を含むものがある。このような断面拡大領域部１１２は、コネクタハウジング１４０内に充填樹脂８０が充填される際、空気溜りが発生することを防止するため、傾斜面１１２ａが形成されている。
また、端子１０を端子ホルダ１３０内に係止するための係止部１３１を保護するための係止部保護リブ１３２が係止部１３１近傍から断面拡大領域１１２の傾斜面１１２ａを含むコネクタハウジング１４０の内面に向けて突出して設けられるようになっている。 By the way, in the connector housing of such a liquid-proof connector, as shown in FIG. 11, the mating connector insertion portion 120 into which the mating connector is fitted and the terminal 10 are held inside via the terminal holder 130. A cross-sectional enlarged region portion 112 is formed in which a cross section perpendicular to the insertion direction D of the terminal 10 is enlarged to a predetermined size from the position 111 in the terminal insertion direction where the insertion portion 120 is communicated to the insertion port 110a of the terminal 10. There are some which include the terminal accommodating portion 110 formed. In such an enlarged cross-sectional area portion 112, an inclined surface 112a is formed in order to prevent an air pocket from being generated when the filling resin 80 is filled in the connector housing 140.
In addition, the connector housing 140 includes a locking portion protection rib 132 for protecting the locking portion 131 for locking the terminal 10 in the terminal holder 130 from the vicinity of the locking portion 131 to the inclined surface 112 a of the cross-sectional enlarged region 112. It is provided so as to protrude toward the inner surface.

しかしながら、上述したような断面拡大領域部１１２を有してなる防液コネクタ１００は、コネクタハウジング１４０へ端子１０の挿入方向Ｄで端子１０の挿入方向Ｄに直交する断面が漸次変化されるため、しかも傾斜面１１２ａの近傍に係止部保護リブ１３２が配置されるため、コネクタハウジング１４０内の充填樹脂８０に伝わる温度の差が大きくなり、熱衝撃が与えられた場合、熱膨張の差に起因して断面拡大領域部１１２周辺の充填樹脂８０にクラックが発生し易くなり、結果的に防液性能が低下してしまうという問題があった。   However, in the liquid-proof connector 100 having the cross-sectional enlarged region portion 112 as described above, the cross section perpendicular to the insertion direction D of the terminal 10 is gradually changed in the insertion direction D of the terminal 10 to the connector housing 140. In addition, since the locking portion protection rib 132 is disposed in the vicinity of the inclined surface 112a, the difference in temperature transmitted to the filling resin 80 in the connector housing 140 increases, and when a thermal shock is applied, the difference is caused by the difference in thermal expansion. As a result, cracks are likely to occur in the filling resin 80 around the enlarged cross-sectional area 112, resulting in a problem that the liquid-proof performance is lowered.

本発明は、上記に鑑みてなされたものであって、防液性能が低下することを防止することができる防液コネクタを提供することを目的とする。   This invention is made | formed in view of the above, Comprising: It aims at providing the liquid-proof connector which can prevent liquid-proof performance falling.

上述した課題を解決し、目的を達成するために、本発明の請求項１に係る防液コネクタは、相手コネクタが嵌入される相手コネクタ嵌入部と、電線と接続されてなる端子が端子ホルダを介して内部に保持され、前記相手コネクタ嵌入部が連通される端子挿入方向奥側位置から前記端子の挿入口に向けて前記端子の挿入方向に直交する断面が所定の大きさに拡大される断面拡大領域部が形成されてなる端子収容部と、を含むコネクタハウジングを有し、該コネクタハウジング内に充填樹脂が充填されて防液される防液コネクタにおいて、前記端子ホルダは、前記端子を係止させる係止部の近傍から前記コネクタハウジングの内面に向けて突出されないように形成されてなり、前記断面拡大領域部は、内面が前記端子の挿入方向に直交する方向から挿入方向に平行にＲ状に屈曲されることによって所定の大きさの断面に拡大されることを特徴とする。   In order to solve the above-described problems and achieve the object, a liquid-proof connector according to claim 1 of the present invention is provided with a mating connector insertion portion into which a mating connector is fitted, and a terminal formed by connecting a wire with a terminal holder. Through which the cross-section orthogonal to the insertion direction of the terminal is enlarged to a predetermined size from the back side position in the terminal insertion direction where the mating connector insertion portion communicates with the insertion port of the terminal A connector housing including a terminal housing portion formed with an enlarged region portion, wherein the terminal holder is associated with the terminal.

本発明の請求項１に係る防液コネクタは、前記端子ホルダが前記端子を係止させる係止部の近傍から前記コネクタハウジングの内面に向けて突出されないように形成されてなり、前記断面拡大領域部が内面が前記端子の挿入方向に直交する方向から挿入方向に平行にＲ状に屈曲されることによって所定の大きさの断面に拡大されるので、前記端子の挿入方向の短い距離で所定の大きさの断面に拡大され前記コネクタハウジング内の前記充填樹脂を均一形状にすることができ、前記充填樹脂のクラックの発生が防止され、結果的に防液性能が低下することを防止することができる。   The liquid-proof connector according to claim 1 of the present invention is formed so that the terminal holder does not protrude toward the inner surface of the connector housing from the vicinity of a locking portion that locks the terminal. Since the inner surface is expanded in a cross section of a predetermined size by bending the inner surface from a direction perpendicular to the insertion direction of the terminal into an R shape parallel to the insertion direction, a predetermined distance is obtained at a short distance in the insertion direction of the terminal. The filling resin in the connector housing can be made to have a uniform shape by being enlarged to a cross section of the size, the occurrence of cracks in the filling resin can be prevented, and consequently the liquid-proof performance can be prevented from being lowered. it can.

Since the length in the insertion direction of the terminal of the terminal accommodating portion is constant, the cylindrical region portion is lengthened by the length of the enlarged cross-sectional area portion in the insertion direction of the terminal. It can be formed. Thereby, the area | region where the said filling resin with which the said connector housing is filled can be filled uniformly can be expanded.

本発明の請求項３に係る防液コネクタは、前記端子と電線との接続部が前記円筒状領域部に配置されるので、前記接続部が均一に形成された前記充填樹脂に覆われることによって、前記接続部の防液性能を向上させることができる。   In the liquid-proof connector according to claim 3 of the present invention, since the connection portion between the terminal and the electric wire is disposed in the cylindrical region portion, the connection portion is covered with the uniformly filled resin. The liquid-proof performance of the connecting part can be improved.

以下、図面を参照して、本発明に係る防液コネクタの好適な実施例を詳細に説明する。   Hereinafter, preferred embodiments of a liquid-proof connector according to the present invention will be described in detail with reference to the drawings.

図１は、本発明の実施例に係る防液コネクタ１の斜視図である。図２は、図１に示した防液コネクタ１の要部断面図である。図３は、図１に示した防液コネクタ１の要部断面を示した側面図である。図４は、図１に示した、コネクタハウジング４０に端子ホルダ３０が取り付けられた状態を示した断面図である。
本発明の実施例に係る防液コネクタ１は、不図示の相手コネクタが嵌入される相手コネクタ嵌入部５０と、端子１０が端子ホルダ３０を介して内部に保持される端子収容部６０とを含むコネクタハウジング４０を有し、コネクタハウジング４０内に充填樹脂８０が充填されるようになっている。 FIG. 1 is a perspective view of a liquid-proof connector 1 according to an embodiment of the present invention. FIG. 2 is a cross-sectional view of a main part of the liquid-proof connector 1 shown in FIG. FIG. 3 is a side view showing a cross section of the main part of the liquid-proof connector 1 shown in FIG. 4 is a cross-sectional view showing a state in which the terminal holder 30 is attached to the connector housing 40 shown in FIG.
The liquid-proof connector 1 according to the embodiment of the present invention includes a mating connector insertion portion 50 into which a mating connector (not shown) is inserted, and a terminal accommodating portion 60 in which the terminal 10 is held through the terminal holder 30. A connector housing 40 is provided, and the connector housing 40 is filled with a filling resin 80.

まず、端子１０について説明する。端子１０は、図３に示すように、電線２０に接続されるものであり、不図示の相手端子に接続される棒状の棒状接続部１１と、電線２０の端末部１０ａに圧着される片状の圧着部１２とを有してなる。圧着部１２は電線２０の端末部１０ａの露出された不図示の導線に圧着されるようになっている。圧着部１２によって接続された端子１０と電線２０との接続部１３は、不図示の導線の一部が外部に露出された状態になっている。このため、充填樹脂８０がコネクタハウジング４０内に充填されることによって、接続部１３が充填樹脂８０によって覆われるようになっている。
なお、この実施例の端子１０は雄型の端子を例示したが、これに限らず、雌型の端子を用いてもよい。 First, the terminal 10 will be described. As shown in FIG. 3, the terminal 10 is connected to the electric wire 20. The terminal 10 is connected to a non-illustrated counterpart terminal, and the piece 10 is crimped to the terminal portion 10 a of the electric wire 20. And the crimping portion 12. The crimping part 12 is crimped to a conductor (not shown) exposed at the terminal part 10 a of the electric wire 20. The connection part 13 between the terminal 10 and the electric wire 20 connected by the crimping part 12 is in a state in which a part of a conducting wire (not shown) is exposed to the outside. For this reason, the filling resin 80 is filled in the connector housing 40, so that the connection portion 13 is covered with the filling resin 80.
In addition, although the terminal 10 of this Example illustrated the male terminal, it is not restricted to this, You may use a female terminal.

次に、端子ホルダ３０について説明する。
端子ホルダ３０は、複数の端子１０をコネクタハウジング４０内の所定位置に保持するものである。この端子ホルダ３０は、合成樹脂からなる略直方体形状をなし、複数の端子収容室３１を有してなる。
各端子収容室３１は、コネクタハウジング４０内に保持される端子１０の数に応じて設けられ、各端子１０が各端子収容室３１内で絶縁可能に離間して保持されるようになっている。
また、各端子収容室３１は、内部の所定位置に端子１０を係止するための弾性片状の係止部３２と、各端子収容室３１に連通され、各端子１０の棒状接続部１１が挿通される端子挿通孔部３３とを有してなる。
この端子挿通孔部３３から相手コネクタ嵌入部５０内に先端が突出された棒状接続部１１が、相手コネクタ嵌入部５０内で不図示の相手端子と接続されるようになっている。
また、図４に示すように、端子ホルダ３０の各端子収容室３１に応じた位置に各端子収容室３１に充填樹脂８０が充填されるように開口された樹脂充填口３４が形成されている。 Next, the terminal holder 30 will be described.
The terminal holder 30 holds the plurality of terminals 10 at predetermined positions in the connector housing 40. The terminal holder 30 has a substantially rectangular parallelepiped shape made of synthetic resin and has a plurality of terminal accommodating chambers 31.
Each terminal accommodating chamber 31 is provided according to the number of terminals 10 held in the connector housing 40, and each terminal 10 is held in each terminal accommodating chamber 31 so as to be insulated and separated. .
Each terminal accommodating chamber 31 communicates with each terminal accommodating chamber 31 and an elastic piece-like engaging portion 32 for engaging the terminal 10 at a predetermined position inside, and the rod-like connecting portion 11 of each terminal 10 is connected to the terminal accommodating chamber 31. It has the terminal insertion hole part 33 penetrated.
The rod-like connecting portion 11 whose tip protrudes from the terminal insertion hole 33 into the mating connector insertion portion 50 is connected to a mating terminal (not shown) in the mating connector insertion portion 50.
Further, as shown in FIG. 4, a resin filling port 34 that is opened so that the filling resin 80 is filled in each terminal accommodating chamber 31 is formed at a position corresponding to each terminal accommodating chamber 31 of the terminal holder 30. .

なお、端子ホルダ３０は、係止部３２の近傍からコネクタハウジング４０の内面４０ｂに向けてリブ等が突出されないように形成されてなる。このため、コネクタハウジング４０と端子ホルダ３０との間に充填される充填樹脂８０が均一形状で充填されるようになっている。   Note that the terminal holder 30 is formed so that ribs and the like do not protrude from the vicinity of the locking portion 32 toward the inner surface 40 b of the connector housing 40. For this reason, the filling resin 80 filled between the connector housing 40 and the terminal holder 30 is filled in a uniform shape.

次に、コネクタハウジング４０について説明する。
コネクタハウジング４０は、相手コネクタ嵌入部５０と、端子収容部６０とを有してなる。 Next, the connector housing 40 will be described.
The connector housing 40 includes a mating connector insertion portion 50 and a terminal accommodating portion 60.

相手コネクタ嵌入部５０は、不図示の相手コネクタが嵌入される部分である。この相手コネクタ嵌入部５０は、ほぼ楕円筒形状をなし、内部に不図示の雄型の相手コネクタが嵌入されることによって、不図示の各相手端子と各端子１０とが接続されるようになっている。   The mating connector insertion portion 50 is a portion into which a mating connector (not shown) is inserted. The mating connector insertion portion 50 has a substantially elliptic cylindrical shape, and a mating mating connector (not shown) is fitted therein, whereby each mating terminal (not shown) and each terminal 10 are connected. ing.

端子収容部６０は、端子１０が端子ホルダ３０を介して内部に保持され、相手コネクタ嵌入部５０が連通される端子挿入方向奥側位置６１から端子１０の挿入口６２に向けて端子１０の挿入方向Ｄに直交する断面が所定の大きさに拡大される断面拡大領域部６３が形成されてなる。
より具体的には、端子収容部６０は、端子挿入方向奥側位置６１から端子１０の挿入口６２に向けて断面拡大領域部６３と、円筒形状の円筒状領域部６４とが順次形成されてなる。すなわち、円筒状領域部６４は、断面拡大領域部６３によって所定の大きさに拡大された断面を有してなる筒状部分である。 The terminal accommodating portion 60 is inserted into the terminal 10 from the back side position 61 in the terminal insertion direction where the terminal 10 is held inside via the terminal holder 30 and the mating connector insertion portion 50 communicates to the insertion port 62 of the terminal 10. A cross-sectional enlarged region 63 in which a cross section perpendicular to the direction D is enlarged to a predetermined size is formed.
More specifically, in the terminal accommodating portion 60, a cross-sectional enlarged region portion 63 and a cylindrical cylindrical region portion 64 are sequentially formed from the position 61 in the terminal insertion direction toward the insertion port 62 of the terminal 10. Become. That is, the cylindrical region portion 64 is a cylindrical portion having a cross section enlarged to a predetermined size by the cross sectional enlarged region portion 63.

断面拡大領域部６３は、内面６０ａが端子１０の挿入方向Ｄに直交する方向から挿入方向Ｄに平行にＲ状に屈曲されることによって所定の大きさの断面に拡大されるようになっている。このため、断面拡大領域部６３は、端子１０の挿入方向Ｄの短い距離で所定の大きさの断面に拡大されるようになっている。すなわち、端子収容部６０の端子１０の挿入方向Ｄの長さを一定とした場合、断面拡大領域部６３が端子１０の挿入方向Ｄで短くされた分、円筒状領域部６４を長く形成することができるようになっている。これにより、コネクタハウジング４０内に充填される充填樹脂８０が均一に充填される領域を広げることができる。   The cross-sectional enlarged region 63 is enlarged to a predetermined cross-section by bending the inner surface 60a from the direction orthogonal to the insertion direction D of the terminal 10 into an R shape parallel to the insertion direction D. . For this reason, the cross-sectional enlarged region 63 is enlarged to a cross section having a predetermined size at a short distance in the insertion direction D of the terminal 10. That is, if the length of the terminal 10 in the insertion direction D of the terminal 10 of the terminal accommodating portion 60 is constant, the cylindrical region portion 64 is formed longer by the length of the cross-sectional enlarged region portion 63 shortened in the insertion direction D of the terminal 10. Can be done. Thereby, the area | region where the filling resin 80 with which the connector housing 40 is filled is uniformly filled can be expanded.

また、断面拡大領域部６３は、図３に示すように、端子１０の挿入方向Ｄでコネクタハウジング４０内を区分けた場合、端子１０と電線２０との接続部１３が配置される区間Ｃから外れている。すなわち、接続部１３が円筒状領域部６４に配置されるようになっている。このため、接続部１３は、均一に形成されてクラックが発生し難くなっている充填樹脂８０に覆われるため、接続部１３のシール性が向上されるようになっている。   In addition, as shown in FIG. 3, when the inside of the connector housing 40 is divided in the insertion direction D of the terminal 10, the cross-sectional enlarged region portion 63 is separated from the section C in which the connection portion 13 between the terminal 10 and the electric wire 20 is disposed. ing. That is, the connecting portion 13 is arranged in the cylindrical region portion 64. For this reason, since the connection part 13 is covered with the filling resin 80 which is formed uniformly and is difficult to generate cracks, the sealing property of the connection part 13 is improved.

また、端子収容部６０は、端子１０の挿入口６２を塞ぐためのシール部材６５ａが配置されるシール部材配置部６５を有してなる。
このシール部材配置部６５は、挿入口６２の内周縁６２ａがシール部材６５ａの外形形状に対応して形成されることによって、シール部材６５ａが内周縁６２ａに密着して配置されるようになっている。 The terminal accommodating portion 60 includes a seal member disposing portion 65 in which a seal member 65a for closing the insertion port 62 of the terminal 10 is disposed.
The seal member placement portion 65 is arranged such that the seal member 65a is in close contact with the inner periphery 62a by forming the inner periphery 62a of the insertion port 62 corresponding to the outer shape of the seal member 65a. Yes.

このような構成の防液コネクタ１は、エポキシ樹脂等の充填樹脂８０が端子１０と電線２０との接続部１３を覆うようにコネクタハウジング４０内に充填されることによって、車輌用自動変速機ケース等の取り付け先となるケース内の油がコネクタハウジング４０を介して外部に漏れないようになっている。   The liquid-proof connector 1 having such a configuration is such that a filling resin 80 such as an epoxy resin is filled in the connector housing 40 so as to cover the connection portion 13 between the terminal 10 and the electric wire 20, so that an automatic transmission case for a vehicle is used. The oil in the case, which is the attachment destination, is prevented from leaking outside through the connector housing 40.

次に、本発明の実施例に係る防液コネクタ１の組み付け手順について、図５を用いて説明する。図５は、本発明の実施例に係る防液コネクタ１の組み付け手順を示した図である。   Next, the assembly procedure of the liquid-proof connector 1 according to the embodiment of the present invention will be described with reference to FIG. FIG. 5 is a diagram showing an assembly procedure of the liquid-proof connector 1 according to the embodiment of the present invention.

まず、作業者は、端子１０の挿入口６２から複数の端子１０をコネクタハウジング４０内に挿入することによって、コネクタハウジング４０内に取り付けられた端子ホルダ３０の各端子収容室３１内に各端子１０をセットする（図５（ａ）参照）。これにより、各端子１０が端子収容室３１内で係止部３２によって係止される。   First, the operator inserts the plurality of terminals 10 into the connector housing 40 from the insertion openings 62 of the terminals 10, whereby each terminal 10 is placed in each terminal accommodating chamber 31 of the terminal holder 30 attached in the connector housing 40. Is set (see FIG. 5A). Thereby, each terminal 10 is locked by the locking portion 32 in the terminal accommodating chamber 31.

その後、作業者は、シール部材６５ａをコネクタハウジング４０に取り付ける（図５（ｂ）参照）。これにより、挿入口６２が封止された状態となる。   Thereafter, the operator attaches the seal member 65a to the connector housing 40 (see FIG. 5B). As a result, the insertion port 62 is sealed.

その後、作業者は、充填樹脂８０をコネクタハウジング４０内に充填し、防液コネクタ１の組み付けが完了される（図５（ｃ）参照）。この充填樹脂８０の充填の際、充填樹脂８０は例えば、相手コネクタ嵌入部５０からコネクタハウジング４０内に注入される。なお、端子１０と電線２０との接続部１３は、端子ホルダ３０の樹脂充填口３４を介して端子収容室３１内に充填された充填樹脂８０によって覆われる。   Thereafter, the operator fills the connector housing 40 with the filling resin 80, and the assembly of the liquid-proof connector 1 is completed (see FIG. 5C). When the filling resin 80 is filled, the filling resin 80 is injected into the connector housing 40 from the mating connector insertion portion 50, for example. The connecting portion 13 between the terminal 10 and the electric wire 20 is covered with a filling resin 80 filled in the terminal accommodating chamber 31 via the resin filling port 34 of the terminal holder 30.

ここで、従来の防液コネクタ１００と、本発明に係る実施例の防液コネクタ１とのそれぞれのコネクタハウジング４０，１１０内にかかる応力を解析するために実施した応力解析試験の結果について図６−図１０を用いて説明する。
なお、この応力解析試験では、防液コネクタ１が設置されるエンジンルーム内の温度が−３０℃から１２０℃の範囲であることを想定して、−３０℃の温度条件にて行ったものである。
図６−図１０は、従来の防液コネクタ１００と、本発明に係る実施例の防液コネクタ１とのそれぞれのコネクタハウジング４０，１１０内にかかる応力分布を点線で示した応力分布図である。なお、図中の上段には従来の防液コネクタ１００を示し、下段には本発明の実施例に係る防液コネクタ１を示し、各応力分布図の左上にその断面位置を示している。また、相対的に最も高い応力がかかる領域を塗りつぶし領域で示している。なお、上下段の応力分布図の塗りつぶし領域は同程度の応力を示している。 Here, FIG. 6 shows the result of the stress analysis test performed to analyze the stress applied to the connector housings 40 and 110 of the conventional liquid-proof connector 100 and the liquid-proof connector 1 of the embodiment according to the present invention. -It demonstrates using FIG.
In this stress analysis test, the temperature in the engine room where the liquid-proof connector 1 is installed is assumed to be in the range of −30 ° C. to 120 ° C., and the temperature analysis is performed at −30 ° C. is there.
6 to 10 are stress distribution diagrams in which the stress distribution applied to the connector housings 40 and 110 of the conventional liquid-proof connector 100 and the liquid-proof connector 1 according to the embodiment of the present invention is indicated by dotted lines. . In addition, the conventional liquid-proof connector 100 is shown in the upper stage in the figure, the liquid-proof connector 1 according to the embodiment of the present invention is shown in the lower stage, and the cross-sectional position is shown in the upper left of each stress distribution diagram. In addition, a region where the highest stress is applied is indicated by a solid region. Note that the filled areas in the upper and lower stress distribution diagrams show the same level of stress.

図６−図１０に示すように、従来の防液コネクタ１００と、本発明に係る実施例の防液コネクタ１との応力分布図を比較すると、本発明の実施例に係る防液コネクタ１が従来の防液コネクタ１００に比して応力が高い領域が少なくなっていることがわかる。
これは、端子ホルダ３０が端子１０を係止させる係止部３２の近傍からコネクタハウジング４０の内面４０ｂに向けて突出される係止部保護リブが設けられないこと、および断面拡大領域部６３が端子１０の挿入方向Ｄに直交する方向から挿入方向Ｄに平行にＲ状に屈曲されることによって所定の大きさの断面に拡大されることによって、充填樹脂８０が端子１０の挿入方向Ｄで均一に形成されるようになっていることが原因であると推定される。
すなわち、コネクタハウジング４０内の充填樹脂８０に伝わる温度の差が小さくなることによって熱膨張の差に起因して発生される応力が低減されたとことが原因と推定される。 As shown in FIGS. 6 to 10, when the stress distribution diagrams of the conventional liquidproof connector 100 and the liquidproof connector 1 of the embodiment according to the present invention are compared, the liquidproof connector 1 according to the embodiment of the present invention is as follows. It can be seen that there are fewer areas where the stress is higher than in the conventional liquid-proof connector 100.
This is because there is no locking portion protection rib protruding from the vicinity of the locking portion 32 where the terminal holder 30 locks the terminal 10 toward the inner surface 40b of the connector housing 40, and the cross-sectional enlarged region portion 63 is The filling resin 80 is uniform in the insertion direction D of the terminal 10 by being bent in an R shape parallel to the insertion direction D from a direction perpendicular to the insertion direction D of the terminal 10 to be expanded to a predetermined size. It is presumed that this is caused by the fact that it is formed.
That is, it is presumed that the stress generated due to the difference in thermal expansion is reduced by reducing the difference in temperature transmitted to the filling resin 80 in the connector housing 40.

本発明の実施例に係る防液コネクタ１は、端子ホルダ３０が端子１０を係止させる係止部３２の近傍からコネクタハウジング４０の内面４０ｂ，６０ａに向けて突出されないように形成されてなり、断面拡大領域部６３が、内面６３ａが端子１０の挿入方向Ｄに直交する方向から挿入方向Ｄに平行にＲ状に屈曲されることによって所定の大きさの断面に拡大されるので、端子１０の挿入方向Ｄの短い距離で所定の大きさの断面に拡大されコネクタハウジング４０内の充填樹脂８０を均一形状にすることができ、充填樹脂８０のクラックの発生が防止され、結果的に防液性能が低下することを防止することができる。   The liquid-proof connector 1 according to the embodiment of the present invention is formed so that the terminal holder 30 does not protrude toward the inner surfaces 40b and 60a of the connector housing 40 from the vicinity of the locking portion 32 that locks the terminal 10. The cross-sectional enlarged region 63 is enlarged to a predetermined cross-section by bending the inner surface 63a from the direction orthogonal to the insertion direction D of the terminal 10 into an R shape parallel to the insertion direction D. The cross section of the connector housing 40 can be enlarged to a uniform cross-section with a short distance in the insertion direction D, and the filling resin 80 in the connector housing 40 can be made into a uniform shape. Can be prevented from decreasing.

また、本発明の実施例に係る防液コネクタ１は、端子収容部３１が端子挿入方向奥側位置６１から端子の挿入口に向けて断面拡大領域部６３と、円筒形状の円筒状領域部６４とが順次形成されてなるので、端子収容部６０の端子１０の挿入方向Ｄの長さを一定とした場合、断面拡大領域部６３が端子１０の挿入方向Ｄで短くされた分、円筒状領域部６４を長く形成することができるようになっている。これにより、コネクタハウジング４０内に充填される充填樹脂８０が均一に充填される領域を広げることができる。   Further, in the liquid-proof connector 1 according to the embodiment of the present invention, the terminal accommodating portion 31 has a cross-sectional enlarged region portion 63 and a cylindrical cylindrical region portion 64 from the rear side position 61 in the terminal insertion direction toward the terminal insertion port. Are formed sequentially, so that when the length of the terminal 10 of the terminal accommodating portion 60 in the insertion direction D is constant, the cylindrical enlarged region 63 is shortened in the insertion direction D of the terminal 10. The part 64 can be formed long. Thereby, the area | region where the filling resin 80 with which the connector housing 40 is filled is uniformly filled can be expanded.

また、本発明の実施例に係る防液コネクタ１は、端子１０と電線２０との接続部１３が円筒状領域部６４に配置されるので、接続部１３が均一に形成された充填樹脂８０に覆われることによって、接続部１３のシール性能を向上させることができる。   Moreover, since the connection part 13 of the terminal 10 and the electric wire 20 is arrange | positioned in the cylindrical area | region part 64, the liquid-proof connector 1 which concerns on the Example of this invention is the filling resin 80 in which the connection part 13 was formed uniformly. By being covered, the sealing performance of the connection part 13 can be improved.

なお、本発明の実施例に係る防液コネクタ１は、円筒形状の円筒状領域部６４を有してなるものを例示したが、これに限らない。すなわち、端子１０の挿入方向Ｄに直交する断面が所定の大きさであれば、その他の形状であってもよい。例えば、角筒形状であってもよい。   In addition, although the liquid-proof connector 1 which concerns on the Example of this invention illustrated what has the cylindrical area | region part 64 of a cylindrical shape, it is not restricted to this. That is, as long as the cross section orthogonal to the insertion direction D of the terminal 10 has a predetermined size, other shapes may be used. For example, a rectangular tube shape may be used.

また、本発明の実施例に係る防液コネクタ１は、複数の端子１０を保持するものを例示したがこれに限らず、１以上の端子１０を保持するものであればよい。   Moreover, although the liquid-proof connector 1 which concerns on the Example of this invention illustrated what hold | maintained the several terminal 10, it should just hold | maintain not only this but the 1 or more terminal 10.
