Description

本発明は、防水機能を有する電気接続用のコネクタに関する。 The present invention relates to an electrical connection connector having a waterproof function.

図１ないし図５は、引用文献１などに見られる従来例の防水コネクタ１を示している。まず、図１および図２の防水コネクタ１は、ワイヤーシール２の２つの孔１５に圧着端子３付きの電線４を挿入してから、ワイヤーシール２の外周に位置保持用のリテーナ６を嵌め込み、これらのワイヤーシール２、圧着端子３、電線４およびリテーナ６をハウジング５の保持孔７に組み込んだ構造となっている。 1 to 5 show a waterproof connector 1 of a conventional example found in cited document 1 and the like. First, in the waterproof connector 1 of FIGS. 1 and 2, after inserting the electric wire 4 with the crimp terminal 3 into the two holes 15 of the wire seal 2, the retainer 6 for holding the position is fitted on the outer periphery of the wire seal 2, The wire seal 2, the crimp terminal 3, the electric wire 4, and the retainer 6 are assembled in the holding hole 7 of the housing 5.

組み込み状態でワイヤーシール２およびリテーナ６は、それらの弾性変形により保持孔７の内周面や電線４の外周面に弾力的に密着することにより、ハウジング５の保持孔７に防水機能を付与している。また、圧着端子３は、一例として雌型の端子であり、保持孔７の中線上で保持孔７に連通する端子収納孔８の内部に納まり、その位置で圧着端子３の係合溝９とハウジング５の係合片１０と係り合いによって、ハウジング５の端子収納孔８から抜け止め状態となり、圧着端子３の先端を端子収納孔８の先端開口面に位置させ、図示しない雄型の端子の受け入れに備える。この従来例の防水コネクタ１によると、リテーナ６が必要となることから、部品点数および組立工数の増加により、製造コストが高くなってしまう。 In the assembled state, the wire seal 2 and the retainer 6 provide a waterproof function to the holding hole 7 of the housing 5 by elastically contacting the inner peripheral surface of the holding hole 7 and the outer peripheral surface of the electric wire 4 by their elastic deformation. ing. In addition, the crimp terminal 3 is a female terminal as an example, and is accommodated in the terminal housing hole 8 communicating with the holding hole 7 on the middle line of the holding hole 7, and the engagement groove 9 of the crimp terminal 3 is located at that position. By engaging with the engaging piece 10 of the housing 5, the terminal 5 is prevented from being detached from the terminal receiving hole 8 of the housing 5, and the tip of the crimp terminal 3 is positioned at the tip opening surface of the terminal receiving hole 8. Prepare for acceptance. According to the waterproof connector 1 of this conventional example, the retainer 6 is required, so that the manufacturing cost increases due to an increase in the number of parts and the number of assembly steps.

つぎに、図３ないし図５の従来の防水コネクタ１は、ワイヤーシール２の２つの孔１５に圧着端子３付きの電線４を挿入してから、これらのワイヤーシール２、圧着端子３および電線４をハウジング５の保持孔７に組み込んだ構造となっている。組み込み状態でワイヤーシール２は、その外周方向の複数の突条１６の弾性変形により保持孔７の内周面に圧接し、同時にワイヤーシール２の２つの孔１５の内周面の弾性変形により電線４の外周面に密着することにより、防水機能を付与している。また、圧着端子３は、この例で雌型の端子であり、保持孔７の中心線上で保持孔７に連通する端子収納孔８の内部に納まり、その位置で圧着端子３の係合溝９とハウジング５の係合片１０と係り合いによってハウジング５の収納孔８から抜け止め状態となり、圧着端子３の先端を端子収納孔８のの先端開口面に位置させ、図示しない雄型の端子の受け入れる。 Next, in the conventional waterproof connector 1 of FIGS. 3 to 5, after inserting the electric wire 4 with the crimp terminal 3 into the two holes 15 of the wire seal 2, the wire seal 2, the crimp terminal 3 and the electric wire 4. Is incorporated in the holding hole 7 of the housing 5. In the assembled state, the wire seal 2 is pressed against the inner peripheral surface of the holding hole 7 by elastic deformation of the plurality of protrusions 16 in the outer peripheral direction, and at the same time, the electric wire is elastically deformed by the inner peripheral surface of the two holes 15 of the wire seal 2. By being in close contact with the outer peripheral surface of 4, the waterproof function is imparted. In addition, the crimp terminal 3 is a female terminal in this example, and is accommodated in the terminal housing hole 8 communicating with the holding hole 7 on the center line of the holding hole 7, and the engagement groove 9 of the crimp terminal 3 is located at that position. Is engaged with the engagement piece 10 of the housing 5 so as to be prevented from coming out of the housing hole 8 of the housing 5, and the tip of the crimp terminal 3 is positioned at the tip opening surface of the terminal housing hole 8. accept.

図３ないし図５の従来の防水コネクタ１によると、リテーナ６が不要であるから、部品点数および組立工数が少なくなり、製造コストを抑えることはできる。しかし、ワイヤーシール２とハウジング５との嵌まり合い位置を規制する手段がなく、その位置の保持は、保持孔７の内周面によるワイヤーシール２の外周面の締め付けによる摩擦的な手段によって行われている。このため、防水性能に限界があり、またハウジング２に組み込まれる圧着端子３や電線４の取り扱いによっては、ワイヤーシール２がハウジング５の正規の位置から離脱してしまい、耐久性や安定性に問題があった。
特開平２００５−２２２８１６号公報 According to the conventional waterproof connector 1 shown in FIGS. 3 to 5, since the retainer 6 is unnecessary, the number of parts and the number of assembling steps are reduced, and the manufacturing cost can be suppressed. However, there is no means for restricting the fitting position of the wire seal 2 and the housing 5, and the holding of the position is performed by frictional means by tightening the outer peripheral surface of the wire seal 2 by the inner peripheral surface of the holding hole 7. It has been broken. For this reason, there is a limit to the waterproof performance, and depending on the handling of the crimp terminal 3 and the electric wire 4 incorporated in the housing 2, the wire seal 2 is detached from the normal position of the housing 5, and there is a problem in durability and stability. was there.

図６ないし図８は、本発明に係る防水コネクタ１を示している。これらの図において、防水コネクタ１は、一例として雌型であり、防水性能付加用の弾性変形可能なワイヤーシール２の電線挿入用の２つの孔１５に、電気接続部品付きの２本の電線４を挿入し、ワイヤーシール２を弾性変形させながらハウジング５の保持孔７に組み込む構造となっている。なお、電気接続部品は、例えば圧着端子３であり、電線４の先端に圧着により接続されている。 6 to 8 show a waterproof connector 1 according to the present invention. In these drawings, the waterproof connector 1 is a female type as an example, and two electric wires 4 with electric connection parts are inserted into two holes 15 for inserting electric wires of an elastically deformable wire seal 2 for adding waterproof performance. Is inserted into the holding hole 7 of the housing 5 while elastically deforming the wire seal 2. The electrical connection component is, for example, a crimp terminal 3 and is connected to the tip of the electric wire 4 by crimping.

組み込み状態でワイヤーシール２は、その外周方向の複数の突条１６の弾性変形により保持孔７の内周面に圧接し、かつワイヤーシール２の孔１５の内周面の縮径方向の弾性変形により電線４の外周面に密着することにより、それらの隙間に高い防水機能を付与している。 In the assembled state, the wire seal 2 is pressed against the inner peripheral surface of the holding hole 7 by elastic deformation of the plurality of protrusions 16 in the outer peripheral direction, and the elastic deformation in the reduced diameter direction of the inner peripheral surface of the hole 15 of the wire seal 2. By adhering closely to the outer peripheral surface of the electric wire 4, a high waterproof function is imparted to the gaps.

この例で電気接続部品としての圧着端子３は、雌型の端子であり、保持孔７の中心線上で保持孔７に連通する端子収納孔８の内部に納まり、その位置で圧着端子３の係合溝９とハウジング５の係合片１０と係り合いによって、ハウジング５の端子収納孔８から抜け止め状態となる。圧着端子３の先端の開口部分は、保持孔７の先端開口面に位置しており、図示しない雄型の端子を受け入れて、それらの間で電気的な接続状態となる。 In this example, the crimp terminal 3 as an electrical connection component is a female terminal, and is accommodated in the terminal housing hole 8 communicating with the holding hole 7 on the center line of the holding hole 7. By engaging with the mating groove 9 and the engagement piece 10 of the housing 5, the terminal 5 is prevented from being detached from the terminal receiving hole 8 of the housing 5. The opening portion at the tip of the crimp terminal 3 is located on the tip opening surface of the holding hole 7 and receives a male terminal (not shown) and is in an electrically connected state between them.

本発明に係る防水コネクタ１は、特徴的な事項として、ハウジング５の保持孔７に組み込んだワイヤーシール２の組み込み位置を維持し、かつワイヤーシール２を抜け止め状態とするために、ワイヤーシール２とハウジング５との間に設けた位置規制手段１１を有している。この位置規制手段１１は、ハウジング５の保持孔７の内部の対向位置に向き合う状態として設けた一対の凹部１２、ワイヤーシール２の外周部に連続して設けた凸部１３の他に、ハウジング５の保持孔７の開口側内面の対向位置に、中心（内側）の方向に張り出す一対の突起１４により構成されている。 The waterproof connector 1 according to the present invention has, as a characteristic matter, the wire seal 2 in order to maintain the assembly position of the wire seal 2 incorporated in the holding hole 7 of the housing 5 and to prevent the wire seal 2 from coming off. And a position restricting means 11 provided between the housing 5 and the housing 5. The position restricting means 11 includes a housing 5 in addition to a pair of recesses 12 provided in a state of facing the opposing positions inside the holding hole 7 of the housing 5 and a protrusion 13 provided continuously on the outer periphery of the wire seal 2. A pair of protrusions 14 projecting in the direction of the center (inner side) at positions facing the opening-side inner surface of the holding hole 7.

この例において、一対の凹部１２は、四角筒状のハウジング５の隣接する稜角部分から対向辺の中程まで対向状態として設けられ、保持孔７から外部に通じる長い孔として形成されている。また凸部１３は、ハウジング５の保持孔７にワイヤーシール２を組み込んだ状態で、凹部１２に対応する位置にあって、外周方向に連続し、凹部１２に嵌まる大きさのフランジ状のものとして形成されている。 In this example, the pair of recesses 12 are provided as opposed states from the adjacent ridge angle portions of the rectangular tubular housing 5 to the middle of the opposite side, and are formed as long holes that lead from the holding holes 7 to the outside. Further, the convex portion 13 is in a flange-like shape that is located in a position corresponding to the concave portion 12 in a state where the wire seal 2 is incorporated in the holding hole 7 of the housing 5, is continuous in the outer peripheral direction, and fits into the concave portion 12. It is formed as.

ハウジング５に対する電線４および電気接続部品としての圧着端子３の組み込み過程で、ハウジング５の保持孔７の内部に、電線４および圧着端子３と一体のワイヤーシール２を弾性変形させながら挿入したときに、ワイヤーシール２の凸部１３は、挿入の最終位置でハウジング５の凹部１２に嵌まり合い、挿入方向に圧接する状態としてハウジング５を抜け止め状態とする。しかも、この挿入過程で、一対の突起１４は、ともに外側に変形しながら凸部１３の挿入を許容しているが、挿入完了時点で、各突起１４は、復帰方向の弾力によってワイヤーシール２の凸部１３の背面に当接して、ワイヤーシール２の後退を阻止し、その位置を規制している。 When the electric wire 4 and the crimp terminal 3 as an electrical connection component are assembled into the housing 5 and the wire seal 2 integrated with the electric wire 4 and the crimp terminal 3 is inserted into the holding hole 7 of the housing 5 while being elastically deformed. The convex portion 13 of the wire seal 2 fits into the concave portion 12 of the housing 5 at the final insertion position, and keeps the housing 5 in a state where it is pressed in the insertion direction. In addition, in this insertion process, the pair of protrusions 14 both allow the protrusions 13 to be inserted while being deformed outward. However, at the time when the insertion is completed, each protrusion 14 is deformed by the elasticity of the return direction. It abuts against the back surface of the convex portion 13 to prevent the wire seal 2 from retreating and restricts its position.

なお、この挿入時の抵抗を減少させるために、凸部１３の挿入方向前面、つまり保持孔７の開口縁に最初に当たる凸部１３の外周稜角部分は、面取りしてある。同様に、突起１４の外側面、つまりワイヤーシール２の挿入時に、ワイヤーシール２に最初に当たる突起１４の端縁部分も、面取りしてある。このため、保持孔７にワイヤーシール２を嵌め合わせるときの力は、小さくてよい。ワイヤーシール２がハウジング５の保持孔７の内部に嵌め合わされると、ワイヤーシール２は、位置規制手段１１の凹部１２、凸部１３および突起１４の係り合いによって抜け止め状態となる。 In order to reduce the resistance at the time of insertion, the front surface in the insertion direction of the convex portion 13, that is, the outer peripheral ridge angle portion of the convex portion 13 that first hits the opening edge of the holding hole 7 is chamfered. Similarly, the outer surface of the protrusion 14, that is, the edge portion of the protrusion 14 that first contacts the wire seal 2 when the wire seal 2 is inserted is also chamfered. For this reason, the force when fitting the wire seal 2 to the holding hole 7 may be small. When the wire seal 2 is fitted into the inside of the holding hole 7 of the housing 5, the wire seal 2 is prevented from coming off due to the engagement of the concave portion 12, the convex portion 13, and the protrusion 14 of the position regulating means 11.

次に、図９は、本発明に係る防水コネクタ１を雌雄型対のものとして構成し、それらを嵌め合わせて、両者を電気的に接続する使用例を示している。雌型の防水コネクタ１と雄型の防水コネクタ１とは、嵌まり合う両者のハウジング５の間に、防水性能付加用の弾性変形可能なリング状のハウジングシール１７を介在させながら、水密状態で嵌まり合う。このとき、雄型の防水コネクタ１の雄型の圧着端子３は、雌型の防水コネクタ１の雌型の圧着端子３に挿入され、電気的に導通状態となる。 Next, FIG. 9 shows a usage example in which the waterproof connector 1 according to the present invention is configured as a male and female pair, and they are fitted together to electrically connect them. The female waterproof connector 1 and the male waterproof connector 1 are in a watertight state with an elastically deformable ring-shaped housing seal 17 for adding waterproof performance interposed between the two housings 5 that fit together. Fit together. At this time, the male crimp terminal 3 of the male waterproof connector 1 is inserted into the female crimp terminal 3 of the female waterproof connector 1 and is electrically connected.

この雄型の防水コネクタ１でも、ワイヤーシール２は、雌型の防水コネクタ１と同様に位置規制手段１１としての凹部１２と凸部１３との嵌め合い、および一対の突起１４の係り止めによって、ハウジング５から抜け止め状態となる。雌型の防水コネクタ１と、雄型の防水コネクタ１との嵌め合わせ状態で、雌型の防水コネクタ１の係止片１８と雄型の防水コネクタ１の係止孔１９とは、係り合って抜け止め状態となっているが、必要に応じて手動または工具により係止片１８と係止孔１９との係り合いを解除すれば、両ハウジング５は、分離可能な状態となる。 Also in this male waterproof connector 1, the wire seal 2 is fitted by the concave portion 12 and the convex portion 13 as the position restricting means 11 and the pair of protrusions 14 are locked like the female waterproof connector 1. The housing 5 is prevented from coming off. When the female waterproof connector 1 and the male waterproof connector 1 are fitted together, the locking piece 18 of the female waterproof connector 1 and the locking hole 19 of the male waterproof connector 1 are engaged with each other. Although it is in a retaining state, both housings 5 can be separated if the engagement between the retaining piece 18 and the retaining hole 19 is released manually or by a tool as necessary.

本発明において、電気接続部品は、圧着端子３に限らず、その他の形式の接続具であってもよい。また、本発明は、ワイヤーシール２を用いて、電線４をハウジング５の内部に挿入する接続形態であれば、雄雌形式のものに限らず、広く応用できる。 In the present invention, the electrical connection component is not limited to the crimp terminal 3, but may be other types of connectors. In addition, the present invention is not limited to the male-female type and can be widely applied as long as it is a connection configuration in which the wire 4 is inserted into the housing 5 using the wire seal 2.
