Description

コネクタおよびコネクタのハウジングConnector and connector housing
　本発明は、コネクタおよびコネクタのハウジングに係り、特に、１つのハウジングに複数の端子が設置されるものに関する。 The present invention relates to a connector and a connector housing, and more particularly to a device in which a plurality of terminals are installed in one housing.
　従来、図１～図６で示すようなコネクタ３０１が知られている（特許文献１参照）。 Conventionally, a connector 301 as shown in FIGS. 1 to 6 is known (see Patent Document 1).
　コネクタ３０１は、ハウジング３０３内のキャビティ３０５に挿入される端子金具（端子）３０７と、キャビティ３０５の内壁に沿った形態であって、キャビティ３０５に対する端子金具３０７の挿入方向と交差する方向へ弾性撓み可能に形成したランス３０９とを備えて構成されている。 The connector 301 has a terminal fitting (terminal) 307 inserted into the cavity 305 in the housing 303 and a shape along the inner wall of the cavity 305, and is elastically bent in a direction intersecting the insertion direction of the terminal fitting 307 with respect to the cavity 305. The lance 309 is formed so as to be possible.
　そして、キャビティ３０５に挿入された端子金具３０７をランス３０９の係止作用により抜止め状態に保持するようになっている。 Then, the terminal fitting 307 inserted into the cavity 305 is held in a retaining state by the locking action of the lance 309.
　なお、コネクタ３０１では、ハウジング３０３に複数のキャビティ３０５が設けられており、ランス３０９が一極毎に成形されている。すなわち、複数のキャビティ３０５のそれぞれにランス３０９が設けられている（１つのキャビティ３０５に対して１つのランス３０９が設けられている）。 In the connector 301, a plurality of cavities 305 are provided in the housing 303, and a lance 309 is formed for each pole. That is, a lance 309 is provided in each of the plurality of cavities 305 (one lance 309 is provided for one cavity 305).
　そして、各キャビティ３０５のそれぞれに複数の端子３０７のそれぞれが挿入されて設置され、各ランス３０９のそれぞれによって、設置された各端子３０７の抜け止めがなされるようになっている。 Each of the plurality of terminals 307 is inserted and installed in each of the cavities 305, and each installed 307 is prevented from being detached by each lance 309.
特開２０１１－１８５６５号公報JP 2011-18565 A
　ところで、従来のコネクタ３０１では、キャビティ３０５に設けられているランス３０９を片持ち梁状にして、端子３０７をキャビティ３０５に挿入するときに端子３０７で押すことで撓ませる必要があるので、図１４（ａ）や図１（ｂ）で示すように、キャビティ３０５の側壁３１１とランス３０９との間に間隙３１３を形成する必要がある。 By the way, in the conventional connector 301, since the lance 309 provided in the cavity 305 needs to be cantilevered and the terminal 307 is inserted into the cavity 305, it is necessary to bend by pushing with the terminal 307. As shown in FIG. 1A and FIG. 1B, it is necessary to form a gap 313 between the side wall 311 of the cavity 305 and the lance 309.
　この間隙３１３によって、お互いが隣接しているキャビティ３０５間の距離（ピッチ）ＰＡ（図１４（ａ）、図５（ａ）参照）が大きくなってしまうという問題がある。 There is a problem that the distance (pitch) PA between the cavities 305 adjacent to each other (see FIG. 14A and FIG. 5A) increases due to the gap 313.
　本発明は、上記問題点に鑑みてなされたものであり、複数のキャビティが設けられているハウジングと、このハウジングのキャビティのそれぞれに挿入されて設置される複数の端子とを備えて構成されたコネクタにおいて、お互いが隣接しているキャビティ間の距離（ピッチ）を小さくすることができるコネクタを提供することを目的とする。 The present invention has been made in view of the above problems, and is configured to include a housing provided with a plurality of cavities and a plurality of terminals inserted and installed in the cavities of the housing. An object of the present invention is to provide a connector capable of reducing the distance (pitch) between cavities adjacent to each other.

That is, the two electric wires 27 with terminals are integrated by the seal member 13. Here, the sealing member 13 and the two electric wires with terminals 27 provided with and integrated with the sealing member 13 are referred to as the electric wires with terminals (terminal assemblies) 29 with the sealing members installed. In the terminal combined body 29, the two electric wires 27 with terminals are aligned in the lateral direction.
　端子結合体２９は、各端子付き電線２７の相手側端子接続部１４を前にして、ワイヤバレル部１７やインシュレーションバレル部１９や電線１１を後にして、ハウジング３の２つのキャビティ７に挿入する。端子結合体２９をハウジング３に設置したとき、シール部材１３の外周がハウジング３のキャビティ７の内周の所定の部位に接触し、この接触によってハウジング３とシール部材１３との間のシールがなされるように構成されている。 The terminal coupling body 29 is inserted into the two cavities 7 of the housing 3 with the wire barrel portion 17, the insulation barrel portion 19, and the electric wire 11 behind the mating terminal connection portion 14 of each terminal-attached electric wire 27.

One lance 9 engages with the terminal coupling body 29 (each of the two electric wires 27 with terminals) accommodated in each of the two cavities 7 to prevent the terminal coupling body 29 from coming off (behind the terminal coupling body 29). (Refer to FIG. 11).
　ランス９は、片持ち梁状に形成されており前後方向に延びている。ランス９の基端３３は、端子結合体２９の挿入方向（前後方向）で、キャビティ７に収容された端子結合体２９から離れて端子結合体２９前側に位置している。 The lance 9 is formed in a cantilever shape and extends in the front-rear direction. The base end 33 of the lance 9 is located on the front side of the terminal combination 29 away from the terminal combination 29 accommodated in the cavity 7 in the insertion direction (front-rear direction) of the terminal combination 29.
　ランス９の先端３５は、端子結合体２９の挿入方向（前後方向）で基端３３よりも後側に位置している。ランス９の先端部（後端部）には係止部３７が設けられている。 The distal end 35 of the lance 9 is located behind the proximal end 33 in the insertion direction (front-rear direction) of the terminal assembly 29. A locking portion 37 is provided at the front end portion (rear end portion) of the lance 9.
　そして、キャビティ７に収容された端子結合体２９の相手側端子接続部１４に係止部３７が係合することで、上述した端子５の抜け止めがなされるように構成されている。 Then, the above-described terminal 5 is prevented from coming off by engaging the engaging portion 37 with the mating terminal connecting portion 14 of the terminal assembly 29 accommodated in the cavity 7.
　１本のランス９には、図１０、図１２や図１４（ｂ）で示すように、２つの係止部３７が設けられており、２つの係止部３７は、横方向でお互いが離れている。端子結合体２９がキャビティ７に収容されランス９による抜け止めがされている状態では、端子結合体２９の２つの相手側端子接続部１４のそれぞれに、２つの係止部３７のそれぞれが係合し上述した端子結合体２９の抜け止めがなされるように構成されている。また、ランス９の先端（後端）３５と、シール部材１３とが、前後方向で僅かに離れている。 As shown in FIGS. 10, 12 and 14 (b), one lance 9 is provided with two locking portions 37. The two locking portions 37 are separated from each other in the lateral direction. ing. In a state where the terminal coupling body 29 is accommodated in the cavity 7 and is prevented from being detached by the lance 9, each of the two locking portions 37 is engaged with each of the two mating terminal connection portions 14 of the terminal coupling body 29. The terminal assembly 29 described above is configured to prevent the terminal assembly 29 from coming off. Moreover, the front-end | tip (rear end) 35 of the lance 9 and the sealing member 13 are slightly separated in the front-back direction.
　シール部材１３は、前後方向で、前端がワイヤバレル部１７のたとえば前端（中間部であってもよい）のところに位置し、後端がインシュレーションバレル部１９から僅かに後側のシース２５の箇所のところに位置している。端子結合体２９がキャビティ７に収容されランス９による抜け止めがなされている状態では、端子結合体２９がハウジング３に対してもっとも前側に位置しており、ランス９の後端とシール部材１３の前端とが僅かに離れている。 The seal member 13 has a front end located in the front and rear direction, for example, at a front end (may be an intermediate portion) of the wire barrel portion 17, and a rear end of the sheath 25 slightly behind the insulation barrel portion 19. Located at the place. In a state in which the terminal coupling body 29 is accommodated in the cavity 7 and is prevented from being detached by the lance 9, the terminal coupling body 29 is located on the most front side with respect to the housing 3, and the rear end of the lance 9 and the sealing member 13 The front end is slightly separated.
　端子５は、金属等の導電性材料で構成された板状の素材を所定形状にし、この所定形状にしたものに適宜折り曲げ加工を施すことで生成されている。相手側端子接続部１４は、矩形な筒状になっており、矩形な筒の内側には、弾性片４１が設けられている。また、相手側端子接続部１４の４つの側壁部のうちの１つの側壁部には、ランス９の係止部３７が係合する切り欠き４３が設けられている。 The terminal 5 is generated by making a plate-shaped material made of a conductive material such as metal into a predetermined shape and appropriately bending the formed material. The mating terminal connecting portion 14 has a rectangular tube shape, and an elastic piece 41 is provided inside the rectangular tube. Further, a notch 43 with which the locking portion 37 of the lance 9 is engaged is provided in one of the four side wall portions of the counterpart terminal connecting portion 14.
　１つの端子５におけるワイヤバレル部１７は、一対で形成されており、端子付き電線２７では、ワイヤバレル部１７が、シース２５が除去されて露出している芯線２３を囲んでいる。１つの端子５におけるインシュレーションバレル部１９も、一対で形成されており、端子付き電線２７では、インシュレーションバレル部１９が、シース２５の前端よりも僅かに後側の部位で電線１１のシース２５の外周のほぼ全周に被さっている。 The wire barrel portion 17 in one terminal 5 is formed as a pair, and in the electric wire 27 with a terminal, the wire barrel portion 17 surrounds the exposed core wire 23 from which the sheath 25 is removed. The insulation barrel portion 19 in one terminal 5 is also formed as a pair, and in the electric wire 27 with a terminal, the insulation barrel portion 19 is slightly behind the front end of the sheath 25 and the sheath 25 of the electric wire 11. It covers almost the entire circumference.
　ハウジング３は、たとえば合成樹脂等の絶縁性の材料で一体成形されている。キャビティ７は、ハウジング３の後端から前側に凹んで形成されており、前側部位４５と後側部位４７とを備えて構成されている。 The housing 3 is integrally formed of an insulating material such as synthetic resin. The cavity 7 is formed to be recessed from the rear end of the housing 3 to the front side, and includes a front side portion 45 and a rear side portion 47.
　前側部位４５は、端子５の相手側端子接続部１４の外形とほぼ同形状である四角柱状に形成されており、端子結合体２９における端子５の数に合わせてたとえば２つ形成されている。これにより、ハウジング３には、２つのキャビティが設けられているものと考えることができる。 The front side portion 45 is formed in a quadrangular prism shape that is substantially the same as the outer shape of the mating terminal connection portion 14 of the terminal 5, and for example, two are formed in accordance with the number of terminals 5 in the terminal combination 29. Thereby, it can be considered that the housing 3 is provided with two cavities.
　後側部位４７は、底面は長円状である柱状に形成されている。前側部位４５の一方の中心軸と後側部位４７の中心軸（長円の一方の円の中心軸）とはお互いが一致しており、前側部位４５の他方の中心軸と後側部位４７の中心軸（長円の他方の円の中心軸）とはお互いが一致している。長円状の後側部位４７を形成する円の内径は、四角柱状の前側部位４５の外径（たとえば、四角柱の底面の矩形の対角線の長さ）よりも大きくなっている。 The rear portion 47 is formed in a columnar shape having an oval bottom. One central axis of the front part 45 and the central axis of the rear part 47 (the central axis of one of the ellipses) coincide with each other, and the other central axis of the front part 45 and the rear part 47 The central axis (the central axis of the other ellipse) coincides with each other. The inner diameter of the circle forming the oval rear portion 47 is larger than the outer diameter of the square columnar front portion 45 (for example, the length of the diagonal diagonal line of the bottom surface of the square column).
　ランス９は、２つの前側部位４５にまたがって設けられており、前後方向では、ランス９の先端（後端）の位置と、前側部位４５の後端の位置とがお互いがほぼ一致している。前側部位４５の前端（キャビティ７の底）と、ハウジング３の前端との間には貫通孔４９が形成されている。 The lance 9 is provided across the two front portions 45, and the front end (rear end) position of the lance 9 and the rear end position of the front portion 45 substantially coincide with each other in the front-rear direction. . A through hole 49 is formed between the front end of the front portion 45 (the bottom of the cavity 7) and the front end of the housing 3.
　さらに説明すると、前側部位４５は、図１４（ｂ）で示すように、縦方向の一対の仕切り壁７３と、横方向の一対の仕切り壁７５とで囲まれているとともに、仕切り壁７１によって仕切られていることで２つになっている。 More specifically, as shown in FIG. 14B, the front side portion 45 is surrounded by a pair of vertical partition walls 73 and a pair of horizontal partition walls 75, and is partitioned by a partition wall 71. It has become two by being done.
　１本のランス９は、縦方向の一対の仕切り壁７３のうちの一方の仕切り壁７３のところに形成されている。一方の仕切り壁７３の横方向の両端部と前端部とには、切り欠き７７が形成されており、これによって、片持ち梁状のランス９が生成されている。なお、縦方向から見ると、切り欠き７７は「コ」字状（Ｕ－ｓｈａｐｅｄ）に形成されている。 The single lance 9 is formed at one partition wall 73 of the pair of partition walls 73 in the vertical direction. Cutouts 77 are formed at both lateral ends and front end portions of one partition wall 73, thereby generating a cantilever-shaped lance 9. When viewed from the vertical direction, the notch 77 is formed in a “U” shape.
　１本のランス９の先端部には、前述したように２つの係止部３７が形成されている。２つの係止部３７は、横方向の中央部に切り欠き７９があることで、横方向で仕切り壁７１の厚さとほぼ同程度離れている。なお、切り欠き７９を削除した構成であってもよい。また、ランス９との干渉を避けるための切り欠き８１が、仕切り壁７１に設けられている。切り欠き８１は、縦方向で仕切り壁７１の端部（ランス９側の端部）に設けられている。 As described above, two locking portions 37 are formed at the tip of one lance 9. The two locking portions 37 are approximately the same as the thickness of the partition wall 71 in the horizontal direction because of the notch 79 in the central portion in the horizontal direction. A configuration in which the notch 79 is deleted may be used. A notch 81 for avoiding interference with the lance 9 is provided in the partition wall 71. The notch 81 is provided at the end of the partition wall 71 (end on the lance 9 side) in the vertical direction.
　また、ハウジング３には、筒状の凹部５１が設けられている。凹部５１は、ハウジング３の前端から後側に凹んで形成されている。凹部５１が設けられていることで、ハウジング３には、凸部５３が形成されている。２つのキャビティ７（前側部位４５）やランス９は、凸部５３の内側に位置している。凸部５３の外周には、環状のパッキン５５が設置されている。筒状の凹部５１の外側には、弾性アーム５９が設けられている。 The housing 3 is provided with a cylindrical recess 51. The recess 51 is formed to be recessed from the front end of the housing 3 to the rear side. Protruding portions 53 are formed in the housing 3 by providing the recessed portions 51. The two cavities 7 (front side portions 45) and the lance 9 are located inside the convex portion 53. An annular packing 55 is installed on the outer periphery of the convex portion 53. An elastic arm 59 is provided outside the cylindrical recess 51.
　端子（たとえば２つのオス端子）が設置された相手側コネクタ（図示せず）が、端子結合体２９が設置されたハウジング３（コネクタ１）に設置されると、相手側コネクタは、凹部５１に入り込んでパッキン５５と弾性アーム５９とに係合する。これによって、コネクタ１と相手側コネクタとの間のシールがなされるとともに、相手側コネクタのコネクタ１からの抜け止めがなされるように構成されている。 When a mating connector (not shown) in which terminals (for example, two male terminals) are installed is installed in the housing 3 (connector 1) in which the terminal combined body 29 is installed, the mating connector is in the recess 51. It enters and engages with the packing 55 and the elastic arm 59. As a result, the connector 1 and the mating connector are sealed, and the mating connector is prevented from coming off from the connector 1.
　また、２つの端子が設置された相手側コネクタがコネクタ１に設置されると、相手側コネクタの端子のそれぞれがハウジング３の貫通孔４９のそれぞれを通って、２つの端子５それぞれの相手側端子接続部１４内に入り込む。これによって、相手側コネクタの端子のそれぞれと端子５それぞれとの接続がなされるようになっている。 Further, when the mating connector on which the two terminals are installed is installed on the connector 1, each of the terminals of the mating connector passes through each of the through holes 49 of the housing 3, and the mating terminal of each of the two terminals 5. It enters into the connection part 14. As a result, each of the terminals of the mating connector and each of the terminals 5 are connected.
　シール部材１３は、たとえば合成樹脂等の絶縁性の材料（ゴムを含む）で一体成形されている。ただし、シール部材１３の弾性係数はハウジング３の弾性係数よりも小さく、シール部材１３は、ハウジング３に比べて弾性変形しやすくなっている。 The seal member 13 is integrally formed of an insulating material (including rubber) such as synthetic resin. However, the elastic coefficient of the seal member 13 is smaller than the elastic coefficient of the housing 3, and the seal member 13 is more easily elastically deformed than the housing 3.
　シール部材１３は、たとえば、後側部位４７とほぼ同様な長円柱状に形成されている。シール部材１３の中心軸（２つの円の中心軸）のそれぞれと２本の電線１１の中心軸のそれぞれとはお互いが一致している。さらに説明すると、シール部材１３では、前後方向（柱の中心軸の延伸方向）で、大径部６１と小径部６３とが交互に繰り返されている。 The seal member 13 is formed in, for example, a long cylindrical shape that is substantially the same as the rear portion 47. Each of the central axes of the sealing member 13 (the central axes of the two circles) and each of the central axes of the two electric wires 11 coincide with each other. More specifically, in the seal member 13, the large diameter portion 61 and the small diameter portion 63 are alternately repeated in the front-rear direction (the extending direction of the central axis of the column).
　大径部６１の外径は、キャビティ７の後側部位４７の内径よりも僅かに大きくなっており、小径部６３の外径は、キャビティ７の後側部位４７の内径よりも僅かに小さくなっている。 The outer diameter of the large diameter portion 61 is slightly larger than the inner diameter of the rear portion 47 of the cavity 7, and the outer diameter of the small diameter portion 63 is slightly smaller than the inner diameter of the rear portion 47 of the cavity 7. ing.
　端子結合体２９をハウジング３に設置し終えたとき、後側部位４７の内壁で押圧されることで、大径部６１が潰れて、端子結合体２９とハウジング３の間のシールがなされるようになっている。 When the terminal assembly 29 has been installed in the housing 3, the large diameter portion 61 is crushed by being pressed by the inner wall of the rear portion 47, and a seal between the terminal assembly 29 and the housing 3 is achieved. It has become.
　ここで、端子結合体２９の製造について説明する。まず、電線１１のシース２５を適宜除去し、一端部で芯線２３を露出させる。続いて、端子５を電線１１に設置する。これによって端子付き電線２７が生成される。この端子付き電線２７を複数本（たとえば２本）生成する。 Here, the manufacture of the terminal assembly 29 will be described. First, the sheath 25 of the electric wire 11 is removed as appropriate, and the core wire 23 is exposed at one end. Subsequently, the terminal 5 is installed on the electric wire 11. Thereby, the electric wire 27 with a terminal is produced | generated. A plurality (for example, two) of the electric wires 27 with terminals are generated.
　続いて、複数本（たとえば２本）の端子付き電線２７を横方向にならべて、シール部材１３をたとえばモールドによって、２本の端子付き電線２７の端子５と電線１１とに密着させて一体的に設置する。これによって、端子結合体２９が生成される。 Subsequently, a plurality of (for example, two) electric wires 27 with terminals are arranged in the horizontal direction, and the sealing member 13 is brought into close contact with the terminals 5 and the electric wires 11 of the electric wires 27 with two terminals by, for example, molding. Install in. As a result, the terminal combination 29 is generated.
　次に、端子結合体２９のハウジング３への設置について説明する。 Next, installation of the terminal assembly 29 on the housing 3 will be described.
　初期状態として、図８で示すように、端子結合体２９がハウジング３の後方でハウジング３から離れているものとする。このとき、端子結合体２９は、相手側端子接続部１４が前側になり、電線１１が後側になっており、横方向および縦方方向で、２つのキャビティ７の位置と、端子結合体２９の２つの端子５の位置とがお互いに一致している。 As an initial state, it is assumed that the terminal assembly 29 is separated from the housing 3 behind the housing 3 as shown in FIG. At this time, the terminal coupling body 29 has the mating terminal connection portion 14 on the front side and the electric wire 11 on the rear side, the position of the two cavities 7 in the horizontal direction and the vertical direction, and the terminal coupling body 29. The positions of the two terminals 5 coincide with each other.
　上記初期状態において、ハウジング３に対して端子結合体２９を前方に移動すると、端子５がキャビティ７に入り込み、端子５の先端がランス９先端部の斜面６５に当接し、ランス９が弾性変形して撓み、シール部材１３がキャビティ７の後側部位４７に入り込み始める（図９、図１０参照）。 In the initial state, when the terminal assembly 29 is moved forward with respect to the housing 3, the terminal 5 enters the cavity 7, the tip of the terminal 5 comes into contact with the inclined surface 65 of the tip of the lance 9, and the lance 9 is elastically deformed. The seal member 13 begins to enter the rear portion 47 of the cavity 7 (see FIGS. 9 and 10).
　端子結合体２９をさらに前方に移動すると、端子５の前端がキャビティ７の底（前端面）に当接し、ランス９が復元し、１本のランス９の２つの係止部３７のそれぞれが２つの相手側端子接続部１４それぞれの切り欠き４３に入り込み、端子結合体２９の抜け止めがなされ、シール部材１３がキャビティ７の後側部位４７に入り込み、ハウジング３とシール部材１３との間のシール（止水）がなされる（図１１、図１２参照）。 When the terminal assembly 29 is moved further forward, the front end of the terminal 5 comes into contact with the bottom (front end surface) of the cavity 7, the lance 9 is restored, and each of the two locking portions 37 of the single lance 9 is 2. The terminal assembly 29 is prevented from coming off and the sealing member 13 enters the rear portion 47 of the cavity 7, and the seal between the housing 3 and the sealing member 13 is entered. (Water stoppage) is performed (see FIGS. 11 and 12).
　コネクタ１によれば、１本のランス９でハウジング３に設置された複数の端子５を係止するように構成されているので、従来のような間隙（ランス９とキャビティ７の側壁との間の間隙）が不要となり、お互いが隣接しているキャビティ７間の距離（ピッチ）を小さくすることができる。 According to the connector 1, a plurality of terminals 5 installed in the housing 3 are locked by a single lance 9, so that a conventional gap (between the lance 9 and the side wall of the cavity 7 is arranged). ) Is not necessary, and the distance (pitch) between the cavities 7 adjacent to each other can be reduced.
　これによって、お互いが隣接している２つのキャビティ７のそれぞれに２つの端子５のそれぞれが挿入されてランス９による抜け止めがなされる場合を例に掲げて詳しく説明する。お互いが隣接している２つのキャビティ７は前述したように横方向にならんでいる。 This will be described in detail by taking as an example a case where each of the two terminals 5 is inserted into each of the two cavities 7 adjacent to each other and the lance 9 prevents the detachment. The two cavities 7 adjacent to each other are aligned in the lateral direction as described above.
　従来のコネクタでは、お互いが隣接している２つのキャビティ２０３は、図１４（ａ）で示すように、側壁２０１で２つに仕切られている。そして、側壁２０１とランス２０５との間の空隙２０７によって、側壁２０１とランス２０５とが寸法Ｐ１だけ離れている。 In the conventional connector, the two cavities 203 adjacent to each other are divided into two by the side wall 201 as shown in FIG. The side wall 201 and the lance 205 are separated from each other by the dimension P1 due to the gap 207 between the side wall 201 and the lance 205.
　これに対して、コネクタ１では、図１４（ｂ）で示すように、仕切り壁（側壁）７１で各キャビティ７が仕切られているが、仕切り壁７１とランス９との間では、横方向で間隙が不要になっており空隙が非存在であるので、お互いが隣接している２つのキャビティ７のピッチＰＢ（図１４（ｂ）参照）を、図１４（ａ）に示すピッチＰＡよりも、「２×Ｐ１」だけ小さくすることができる。 On the other hand, in the connector 1, as shown in FIG. 14B, each cavity 7 is partitioned by a partition wall (side wall) 71, but between the partition wall 71 and the lance 9, in the lateral direction. Since the gap is unnecessary and there is no gap, the pitch PB (see FIG. 14B) of the two cavities 7 that are adjacent to each other is more than the pitch PA shown in FIG. It can be reduced by “2 × P1”.
　なお、図１４は、コネクタ１を模式的に示したものであるので、ランス９，２０５等の形態が、図８～図１２で示したものと相違している。 14 schematically shows the connector 1, the form of the lances 9, 205, etc. is different from that shown in FIGS. 8 to 12.
　また、コネクタ１によれば、１本のランス９で係止される複数の端子５が、これらの端子５と電線１１との接続部をシールしているシール部材１３によって一体化されているので、端子５のハウジング３への設置工数を削減することができ、端子５と電線１１との接続部のシールがなされているとともに、ハウジング３とシール部材１３（端子結合体２９）との間のシールがなされる。 Moreover, according to the connector 1, since the several terminal 5 latched by the one lance 9 is integrated by the sealing member 13 which has sealed the connection part of these terminals 5 and the electric wire 11. The number of installation steps of the terminal 5 to the housing 3 can be reduced, the connecting portion between the terminal 5 and the electric wire 11 is sealed, and the space between the housing 3 and the seal member 13 (terminal combined body 29). A seal is made.
