Description

本発明は、コネクタに関する。 The present invention relates to a connector.

従来、雄端子に設けられた雄側接続部が挿入される接続筒部を備えた雌端子として、特許文献１に記載のものが知られている。
接続筒部内には、雄側接続部に弾性的に接触することで、雄側接続部と電気的に接続される弾性接触片が形成されている。弾性接触片の幅方向中央には突部が形成されており、この突部は、雄側接続部の挿入方向に延びる形態で雄側接続部の下面に形成された凹溝に嵌合可能とされている。そして、雄側接続部と弾性接触片とが電気的に接続されると、突部が凹溝内に嵌合され、雄側接続部と弾性接触片とが互いに幅方向に移動することが阻止されることにより、雄側接続部と弾性接触片との間の微摺動が抑制されている。 Conventionally, the thing of patent document 1 is known as a female terminal provided with the connection cylinder part in which the male side connection part provided in the male terminal is inserted.
In the connection cylinder part, the elastic contact piece electrically connected with the male side connection part by elastically contacting with the male side connection part is formed. A protrusion is formed at the center in the width direction of the elastic contact piece, and this protrusion can be fitted in a groove formed on the lower surface of the male connection part in a form extending in the insertion direction of the male connection part. Has been. Then, when the male side connection portion and the elastic contact piece are electrically connected, the protrusion is fitted in the concave groove, and the male side connection portion and the elastic contact piece are prevented from moving in the width direction. By doing so, the fine sliding between the male side connection part and the elastic contact piece is suppressed.

ところで、これらの端子をハウジング内に抜け止めする手段としては、例えば、ハウジング内に設けられたランスによって端子を後方から係止する方法がある。
ところが、一般に、ランスは、ランスの基端部を支点にランスの前端部が円弧状を描くように弾性変形可能に構成されているから、端子の挿入過程において、ランスは端子との干渉により、ランスの前端部が斜め前方に変位するように弾性変形し、端子が正規に挿入されると弾性復帰することで、端子を後方から係止する。このため、端子が正規の位置まで挿入されてランスが弾性復帰した状態では、端子とランスとの間にランスが斜め前方に変位した分だけクリアランスが存在することになる。したがって、雄端子を収容する雄ハウジングと雌端子を収容する雌ハウジングとが嵌合された状態で振動を受けると、各ハウジング内において端子が前後方向にがたつき、雌端子の弾性接触片と雄端子のタブとの間でいわゆる微摺動摩耗が生じて、端子間の接触抵抗が増大してしまう虞がある。 By the way, as a means for preventing these terminals from coming off in the housing, for example, there is a method of locking the terminals from the rear by a lance provided in the housing.
However, in general, the lance is configured to be elastically deformed so that the front end of the lance forms an arc shape with the basal end of the lance as a fulcrum. The front end portion of the lance is elastically deformed so as to be displaced obliquely forward, and when the terminal is properly inserted, the terminal is elastically restored to lock the terminal from the rear. For this reason, in a state where the terminal is inserted to the proper position and the lance is elastically restored, there is a clearance between the terminal and the lance so as to be displaced obliquely forward. Therefore, when vibration is received in a state in which the male housing that accommodates the male terminal and the female housing that accommodates the female terminal are fitted, the terminal rattles in the front-rear direction within each housing, and the elastic contact piece of the female terminal There is a possibility that so-called fine sliding wear occurs between the tabs of the male terminals, and the contact resistance between the terminals increases.

本発明は上記のような事情に基づいて完成されたものであって、端子間における微摺動摩耗を抑制することを目的とする。 The present invention has been completed based on the above situation, and an object thereof is to suppress fine sliding wear between terminals.

上記の目的を達成するための手段として本発明は、フード部を有する雄ハウジングと、前記フード部内に嵌合される雌ハウジングと、前記雌ハウジング内に後側から収容され、前記雌ハウジングが前記フード部内に嵌合された際に、前記雄ハウジングに収容された雄端子に接続される雌端子とを備えたコネクタであって、前記雌端子は、前記雄端子に設けられた雄側接続部が挿入されて接続される接続筒部を有しており、前記雌ハウジングの外壁には、前記フード部内に前記雌ハウジングが嵌合されると、前記フード部の内壁に押圧されることで、前記雌ハウジング内に向かって変位し、前記雌端子を前側に向かって押圧する押圧部が設けられており、前記雌端子には、前記押圧部に押圧されることにより、前記接続筒部内に挿入された前記雄側接続部を前側に押し出して前記雄端子を前記雄ハウジングに押しつける押し出し部が設けられているところに特徴を有する。 As means for achieving the above object, the present invention includes a male housing having a hood portion, a female housing fitted in the hood portion, and a rear housing in the female housing, wherein the female housing is And a female terminal connected to the male terminal accommodated in the male housing when fitted into the hood, wherein the female terminal is provided on the male terminal. Is connected to the outer wall of the female housing, and when the female housing is fitted into the hood, the inner wall of the hood is pressed. A pressing portion that is displaced toward the inside of the female housing and presses the female terminal toward the front side is provided, and the female terminal is inserted into the connecting tube portion by being pressed by the pressing portion. Said Having characterized in that the extrusion unit to press the male terminal to the male housing by extruding side connecting portion to the front is provided.

このような構成のコネクタによると、雄端子を雄ハウジングに押しつけることで、雄ハウジングにおける雄端子の前後方向のがたつきを抑制すると共に、雄側接続部と雌ハウジングの押圧部とによって雌端子を前後方向に挟み付けることで、雌ハウジングにおける雌端子の前後方向のがたつきをなくすことができる。これにより、接続筒部と雄側接続部との間において微摺動摩耗が生じることを抑制し、端子間の接触抵抗の増加を抑制することができる。 According to the connector having such a configuration, the male terminal is pressed against the male housing, thereby suppressing the rattling of the male terminal in the front-rear direction of the male housing and the female terminal by the male side connection portion and the pressing portion of the female housing. The back and forth rattling of the female terminal in the female housing can be eliminated. Thereby, it can suppress that fine sliding wear arises between a connection cylinder part and a male side connection part, and can suppress the increase in the contact resistance between terminals.

本発明の実施の態様として、以下の構成が好ましい。
前記押圧部は、前記雌端子を前記雌ハウジング内に挿入する過程において、前記雌端子と干渉することで外側に向かって弾性変形し、前記雌端子が前記雌ハウジング内の正規の位置まで至ると、前記雌端子との干渉状態が解除されて弾性復帰することで、前記雌端子を後側から係止するランスである構成としてもよい。
このような構成によると、雌端子を後側から係止するランスを、押圧部として兼用することができる。これにより、押圧部を雌ハウジングに別途設ける場合に比べて、雌ハウジングの構造を簡素化することができ、雌ハウジングが大型化することを抑制することができる。 The following configuration is preferable as an embodiment of the present invention.
In the process of inserting the female terminal into the female housing, the pressing portion elastically deforms outward by interfering with the female terminal, and the female terminal reaches a proper position in the female housing. The lance that locks the female terminal from the rear side when the interference state with the female terminal is released and elastically restored may be adopted.
According to such a structure, the lance which latches a female terminal from the rear side can be used as a press part. Thereby, compared with the case where a press part is separately provided in a female housing, the structure of a female housing can be simplified and it can suppress that a female housing enlarges.

前記雌端子は、前記接続筒部の後端縁から前側に向かって屈曲させた延出片を有しており、前記延出片の後端部が前記押圧部に押圧される被押圧部とされ、前記延出片の前端部が前記押し出し部とされている構成としてもよい。
このような構成によると、押圧部によって押圧される押圧力を、延出片のみを介して雄側接続部に伝えることができるから、例えば、接続筒部において、押し出し部と被押圧部とを個別に形成する場合に比べて、押圧部によって被押圧部を確実に押圧することができると共に、接続筒部の構造を簡素化することができる。 The female terminal has an extending piece bent toward the front side from the rear end edge of the connecting cylinder part, and a pressed part in which the rear end part of the extending piece is pressed against the pressing part; Further, the front end portion of the extending piece may be configured as the pushing portion.
According to such a configuration, since the pressing force pressed by the pressing portion can be transmitted to the male side connection portion only through the extension piece, for example, in the connection tube portion, the extrusion portion and the pressed portion are connected. Compared with the case of forming individually, the pressed portion can be surely pressed by the pressing portion, and the structure of the connecting tube portion can be simplified.

前記押し出し部は、前記雄側接続部の挿入方向と交差する方向に前記延出片を屈曲させて形成されている構成としてもよい。
このような構成によると、接続筒部内において雄側接続部が挿入方向と交差する方向に位置ずれしたとしても、雄側接続部と押し出し部とを当接し易くすると共に、雄側接続部を押し出し部によって確実に押し出すことができる。 The pushing portion may be formed by bending the extending piece in a direction intersecting the insertion direction of the male side connecting portion.
According to such a configuration, even if the male side connecting portion is displaced in the direction intersecting the insertion direction in the connecting cylinder portion, the male side connecting portion and the pushing portion are easily brought into contact with each other, and the male side connecting portion is pushed out. It can be reliably pushed out by the part.

前記接続筒部において前記延出片の側方には、前記雌端子が後側に引っ張られた際に、前記押圧部によって後側から係止される被係止部が形成されている構成としてもよい。
例えば、延出片の後端部である被押圧部のみが押圧部によって後側から係止される場合、雌端子が後側に強く引っ張られると、延出片が前側に向かって過度撓みすることで、延出片が破損する虞がある。ところが上記の構成によると、雌端子が後側に強く引っ張られた際には、被係止部が押圧部によって後側から係止されるから、延出片を破損させることなく、雌端子を確実に抜け止めすることができる。 In the connecting tube portion, a side portion of the extending piece is formed with a locked portion that is locked from the rear side by the pressing portion when the female terminal is pulled rearward. Also good.
For example, when only the pressed portion that is the rear end portion of the extended piece is locked from the rear side by the pressing portion, when the female terminal is strongly pulled to the rear side, the extended piece is excessively bent toward the front side. As a result, the extended piece may be damaged. However, according to the above configuration, when the female terminal is strongly pulled to the rear side, the locked portion is locked from the rear side by the pressing portion. It can be surely retained.

前記押圧部の前記雌端子と当接する位置には、前記雌ハウジングの内側から外側に向かうほど前方に向かって傾斜するテーパ状の押圧面が形成されている構成としてもよい。
このような構成によると、押圧部が変位する際に、押圧面によって端子を滑らかに前側に押圧することができる。これにより、雄ハウジングのフード部へ雌ハウジングを円滑に挿入することができ、作業性・操作感に優れる。 It is good also as a structure which the taper-shaped press surface which inclines toward the front is formed in the position which contact | abuts with the said female terminal of the said press part toward the outer side from the inner side of the said female housing.
According to such a configuration, when the pressing portion is displaced, the terminal can be smoothly pressed to the front side by the pressing surface. Thereby, a female housing can be smoothly inserted in the hood part of a male housing, and it is excellent in workability | operativity and operation feeling.

前記押圧部には、前記雌ハウジングの外面より外方に突出する突出部が設けられており、前記雌ハウジングが前記フード部内に嵌合されると前記突出部が前記フード部の内壁に押圧されることで前記押圧部が前記雌ハウジング内に向かって変位する構成としてもよい。
例えば、押圧部を雌ハウジング内に向かって変位させる手段として、フード部内に突起を設け、フード部と雌ハウジングとが正規の嵌合状態に至った際に、突起によって押圧部を雌ハウジング内に押圧するといった方法も考えられる。しかしながら、このような構成によると、フード部内に突起を設けるための型抜き孔を設ける必要ある。
ところが、上記の構成によると、押圧部に突出部を設けるだけで、押圧部を雌ハウジング内に向かって変位させることができる。すなわち、雄ハウジングの構成を変更することなく、押圧部を雌ハウジング内に向かって変位させることができる。 The pressing portion is provided with a protruding portion that protrudes outward from the outer surface of the female housing. When the female housing is fitted into the hood portion, the protruding portion is pressed against the inner wall of the hood portion. Thus, the pressing portion may be displaced toward the inside of the female housing.
For example, as a means for displacing the pressing portion into the female housing, a protrusion is provided in the hood portion, and when the hood portion and the female housing reach a normal fitting state, the pressing portion is inserted into the female housing by the protrusion. A method of pressing is also conceivable. However, according to such a configuration, it is necessary to provide a punching hole for providing a protrusion in the hood portion.
However, according to the above configuration, the pressing portion can be displaced toward the inside of the female housing simply by providing the pressing portion with the protrusion. That is, the pressing portion can be displaced toward the inside of the female housing without changing the configuration of the male housing.

前記押圧部は、前記雌端子が前記雌ハウジングに対して半挿入状態のときに、前記フード部の開口縁に当接することで前記フード部内への前記雌ハウジングの挿入を規制する半挿入検知面を有している構成としてもよい。
このような構成によると、雄ハウジングのフード部と雌ハウジングとが嵌合できないことで、雌端子が半挿入であることを検知することができる。すなわち、雌端子および雄端子のがたを詰めると共に、雌端子を後側から係止するランスを、雌端子の半挿入検知機構として兼用することができる。これにより、３つの機能を個別に設ける場合に比べて、コネクタの構造を格段に簡素化することができる。 The pressing portion is a semi-insertion detection surface that restricts insertion of the female housing into the hood portion by abutting against an opening edge of the hood portion when the female terminal is in a semi-insertion state with respect to the female housing. It is good also as a structure which has.
According to such a configuration, since the hood portion of the male housing and the female housing cannot be fitted, it can be detected that the female terminal is half-inserted. In other words, the female terminal and male terminal can be packed together, and a lance that locks the female terminal from the rear side can also be used as a half-insertion detection mechanism of the female terminal. Thereby, compared with the case where three functions are provided separately, the structure of the connector can be greatly simplified.

本発明によれば、端子間における微摺動摩耗を抑制することができる。 According to the present invention, fine sliding wear between terminals can be suppressed.

＜実施形態１＞
本発明の実施形態１について図１乃至図５を参照して説明する。
本実施形態のコネクタは、図１に示すように、電線Ｗの端末に接続される雄コネクタ５０と、雄コネクタ５０に嵌合される雌コネクタ３０とを備えて構成されている。なお、以下の説明において、上下方向とは、図１における上下方向を基準とし、前後方向とは図１における左右方向を基準とし、雌コネクタ３０と雄コネクタ５０とが互いに嵌合する側を前側として説明する。 <Embodiment 1>
Embodiment 1 of the present invention will be described with reference to FIGS.
As shown in FIG. 1, the connector of the present embodiment includes a male connector 50 connected to the end of the electric wire W and a female connector 30 fitted to the male connector 50. In the following description, the vertical direction is based on the vertical direction in FIG. 1, the front-back direction is based on the horizontal direction in FIG. 1, and the side on which the female connector 30 and the male connector 50 are fitted together is the front side. Will be described.

雄コネクタ５０は、図１に示すように、合成樹脂製の雄ハウジング５１と、雄ハウジング５１内に収容される雄端子６０とを備えて構成されている。
雄端子６０は、導電性を有する金属板材をプレス加工することにより形成されており、前後方向に延びる幅広なタブ状の雄側接続部６１と、雄側接続部６１の後方に連なる箱形状の本体部６２と、本体部６２の後方に連なる雄側電線接続部６３とを備えて構成されている。
雄側電線接続部６３は、電線Ｗの端末に露出された芯線に圧着されるワイヤバレル部６４と、電線Ｗの絶縁被覆に圧着されるインシュレーションバレル部６５とを備えて構成されており、ワイヤバレル部６４とインシュレーションバレル部６５とが電線Ｗに圧着されることで、雄端子６０が電線Ｗに対して電気的に接続されている。 As shown in FIG. 1, the male connector 50 includes a male housing 51 made of synthetic resin and a male terminal 60 accommodated in the male housing 51.
The male terminal 60 is formed by pressing a conductive metal plate, and has a wide tab-like male side connection portion 61 extending in the front-rear direction, and a box-like shape connected to the rear side of the male side connection portion 61. The main body 62 and the male electric wire connecting part 63 connected to the rear of the main body 62 are provided.
The male-side electric wire connecting portion 63 includes a wire barrel portion 64 that is crimped to the core wire exposed at the end of the electric wire W, and an insulation barrel portion 65 that is crimped to the insulating coating of the electric wire W. The male terminal 60 is electrically connected to the electric wire W by crimping the wire barrel portion 64 and the insulation barrel portion 65 to the electric wire W.

雄ハウジング５１は、前後方向に長い形態をなしており、雄端子６０を収容する端子収容部５２と、端子収容部５２の前方に連なって設けられたフード部５３とを備えて構成されている。
端子収容部５２の内部には、前後方向に貫通する雄側キャビティ５４が設けられており、この雄側キャビティ５４内には、後方から雄端子６０が収容されるようになっている。また、雄側キャビティ５４内には、雄側キャビティ５４に収容された雄端子６０を後方から係止する雄側ランス５５が設けられている。雄側ランス５５は、雄側キャビティ５４の下側内壁から前方に向かって斜め上方に片持ち状に延びる形態をなしており、下方向に弾性変形可能とされている。そして、雄側ランス５５は、雄側キャビティ５４内に後方から雄端子６０が挿入されると、雄端子６０の本体部６２と干渉して下方に向かって弾性変形する。また、雄端子６０が正規の位置まで挿入されると、雄側ランス５５と本体部６２との干渉状態が解除され、雄側ランス５５が弾性復帰することで雄側ランス５５が本体部６２の下端部に設けられたランス孔６６に嵌まり込み本体部６２を後方から係止している。 The male housing 51 has a shape that is long in the front-rear direction, and includes a terminal accommodating portion 52 that accommodates the male terminal 60, and a hood portion 53 that is provided in front of the terminal accommodating portion 52. .
A male side cavity 54 penetrating in the front-rear direction is provided inside the terminal accommodating portion 52, and the male terminal 60 is accommodated from the rear side in the male side cavity 54. In the male cavity 54, a male lance 55 for locking the male terminal 60 accommodated in the male cavity 54 from the rear is provided. The male lance 55 has a form extending in a cantilever manner obliquely upward from the lower inner wall of the male cavity 54 and is elastically deformable downward. When the male terminal 60 is inserted into the male cavity 54 from behind, the male lance 55 interferes with the main body 62 of the male terminal 60 and elastically deforms downward. Further, when the male terminal 60 is inserted to the proper position, the interference state between the male lance 55 and the main body portion 62 is released, and the male lance 55 is elastically restored, so that the male lance 55 is attached to the main body portion 62. It fits into a lance hole 66 provided at the lower end and locks the main body 62 from the rear.

なお、雄側ランス５５は片持ち状をなしているため、雄側ランス５５の基端部を支点に雄側ランス５５の前端部が斜め前方に変位するように弾性変形する。このため、雄端子６０が正規の位置まで挿入されて雄側ランス５５が弾性復帰した状態では、図１に示すように、ランス孔６６の前側内壁と雄側ランス５５との間には雄側ランス５５が斜め前方に変位した分だけクリアランスＣが生じている。 Since the male lance 55 is cantilevered, the male lance 55 is elastically deformed so that the front end of the male lance 55 is displaced obliquely forward with the base end of the male lance 55 as a fulcrum. Therefore, in the state where the male terminal 60 is inserted to the proper position and the male lance 55 is elastically restored, the male side lance 55 has a male side lance 55 between the front inner wall and the male lance 55 as shown in FIG. A clearance C is generated as much as the lance 55 is displaced obliquely forward.

フード部５３は、前方に向かって略矩形状に開口しており、フード部５３の奥壁５３Ａからは端子収容部５２に収容された雄端子６０の雄側接続部６１が前方に突出している。 The hood part 53 opens in a substantially rectangular shape toward the front, and the male side connection part 61 of the male terminal 60 accommodated in the terminal accommodating part 52 projects forward from the rear wall 53A of the hood part 53. .

雌コネクタ３０は、電線Ｗの端末に接続される雌端子２０と、雌端子２０が収容される雌ハウジング３１とを備えて構成されている。
雌端子２０は、導電性を有する金属板材をプレス加工することにより形成されており、図４および図５に示すように、雄端子６０の雄側接続部６１が挿入される接続筒部２１と、接続筒部２１の後方に連なって設けられた電線接続部２２とを備えて構成されている。 The female connector 30 includes a female terminal 20 connected to the end of the electric wire W and a female housing 31 in which the female terminal 20 is accommodated.
The female terminal 20 is formed by pressing a conductive metal plate material, and as shown in FIGS. 4 and 5, the connection cylinder portion 21 into which the male side connection portion 61 of the male terminal 60 is inserted, The electric wire connecting part 22 is provided to be connected to the rear of the connecting cylinder part 21.

接続筒部２１は、横方向に幅広な略角筒状をなし、接続筒部２１の内部には、前端上縁から後方に向かって折り返された弾性接触片２３が設けられている。弾性接触片２３は、上方向に弾性変形可能とされており、弾性接触片２３の下面には、下方に向かって膨出する接点部２３Ａが設けられている。そして、雄側接続部６１が接続筒部２１内に挿入されると、図２に示すように、接続筒部２１の底板２１Ａと弾性接触片２３とが上下方向に雄側接続部６１を弾性的に挟み付け、接点部２３Ａが雄側接続部６１に接触することで、雄側接続部６１と弾性接触片２３とが電気的に接続されるようになっている。
接続筒部２１の後端下縁における幅方向両側には、図３乃至図５に示すように、後述する雌ハウジング３１のランス(「押圧部」の一例)３４によって後方から係止される一対の被係止部２６が形成されている。これらの被係止部２６は、前方に向かうほど内側から外側に向かって傾斜するテーパ状に形成されている。 The connecting tube portion 21 has a substantially rectangular tube shape that is wide in the horizontal direction, and an elastic contact piece 23 that is folded back from the upper edge of the front end is provided inside the connecting tube portion 21. The elastic contact piece 23 can be elastically deformed upward, and a contact portion 23 </ b> A that bulges downward is provided on the lower surface of the elastic contact piece 23. When the male side connecting portion 61 is inserted into the connecting tube portion 21, as shown in FIG. 2, the bottom plate 21A of the connecting tube portion 21 and the elastic contact piece 23 elastically move the male side connecting portion 61 in the vertical direction. Thus, the male side connecting portion 61 and the elastic contact piece 23 are electrically connected to each other when the contact portion 23A contacts the male side connecting portion 61.
On both sides in the width direction at the lower edge of the rear end of the connecting tube portion 21, as shown in FIGS. 3 to 5, a pair locked from behind by a lance (an example of a “pressing portion”) 34 of a female housing 31 described later. The to-be-latched part 26 is formed. These locked portions 26 are formed in a tapered shape that inclines from the inside toward the outside as it goes forward.

電線接続部２２は、電線Ｗの端末に露出された芯線に圧着されるワイヤバレル部２４と、電線Ｗの絶縁被覆に圧着されるインシュレーションバレル部２５とを備えて構成されており、ワイヤバレル部２４とインシュレーションバレル部２５とが電線Ｗに圧着されることで、雌端子２０が電線Ｗに対して電気的に接続されている。 The electric wire connection portion 22 includes a wire barrel portion 24 that is crimped to the core wire exposed at the end of the electric wire W, and an insulation barrel portion 25 that is crimped to the insulating coating of the electric wire W. The female terminal 20 is electrically connected to the electric wire W by the portion 24 and the insulation barrel portion 25 being crimped to the electric wire W.

雌ハウジング３１は、図１および図４に示すように、前後方向に長いブロック状をなしており、雄ハウジング５１のフード部５３内に適合して嵌合されるようになっている。なお、図示省略されているが、雌ハウジング３１と雄ハウジング５１とは、両ハウジング３１，５１に亘って設けられたロック機構によって嵌合状態にロックされるようになっている。 As shown in FIGS. 1 and 4, the female housing 31 has a long block shape in the front-rear direction, and is fitted and fitted into the hood portion 53 of the male housing 51. Although not shown, the female housing 31 and the male housing 51 are locked in a fitted state by a lock mechanism provided across the housings 31 and 51.

雌ハウジング３１の内部には、前後方向に開口するキャビティ３２が形成されており、キャビティ３２の後端開口から雌端子２０が収容されるようになっている。また、キャビティ３２の前端開口は、雌ハウジング３１の前壁３１Ａに設けられた端子挿通孔３３とされ、フード部５３内に雌ハウジング３１が嵌合されると、図２に示すように、雄端子６０の雄側接続部６１が端子挿通孔３３を通して雌端子２０の接続筒部２１に挿入されるようになっている。
また、雌ハウジング３１には、図１乃至図４に示すように、キャビティ３２内に収容された雌端子２０を後方から係止するランス（「押圧部」の一例）３４が形成されている。このランス３４は、雌ハウジング３１の底壁３１Ｂにスリット３５を設けることで前後方向に延びる片持ち状に形成されており、ランス３４の前端部は自由端とされている。また、ランス３４は、上下方向に弾性変形可能とされており、雌ハウジング３１の前後方向略中央部に位置している。 A cavity 32 that opens in the front-rear direction is formed inside the female housing 31, and the female terminal 20 is received from the rear end opening of the cavity 32. Further, the front end opening of the cavity 32 is a terminal insertion hole 33 provided in the front wall 31A of the female housing 31, and when the female housing 31 is fitted into the hood portion 53, as shown in FIG. The male connection portion 61 of the terminal 60 is inserted into the connection tube portion 21 of the female terminal 20 through the terminal insertion hole 33.
Further, as shown in FIGS. 1 to 4, the female housing 31 is formed with a lance (an example of a “pressing portion”) 34 for locking the female terminal 20 accommodated in the cavity 32 from the rear. The lance 34 is formed in a cantilever shape extending in the front-rear direction by providing a slit 35 in the bottom wall 31B of the female housing 31, and a front end portion of the lance 34 is a free end. The lance 34 can be elastically deformed in the vertical direction, and is located at a substantially central portion in the front-rear direction of the female housing 31.

ランス３４の前側上端部には、上方に突出した形態の端子係止部３６が設けられている。この端子係止部３６は、前後方向略中央部に頂点を有する山形状に形成されている。このため、端子係止部３６の前面は、前側に向かうほど下側(雌ハウジング３１の内側から外側）に向かって傾斜するテーパ状をなし、端子係止部３６の後面は、後側に向かうほど下側に向かって傾斜するテーパ状をなしている。そして、キャビティ３２内に雌端子２０が後方から挿入されると、雌端子２０の接続筒部２１が端子係止部３６の後面に後方から当接して、接続筒部２１が端子係止部３６に乗り上げ、ランス３４を下方に向かって弾性変形させる。そして、雌端子２０が正規の位置に至ると、接続筒部２１と端子係止部３６との干渉状態が解除されてランス３４が弾性復帰し、接続筒部２１の後端下縁における一対の被係止部２６が端子係止部３６によって後方から係止され、雌端子２０が雌ハウジング３１内に抜け止めされる。 A terminal locking portion 36 that protrudes upward is provided at the front upper end of the lance 34. The terminal locking portion 36 is formed in a mountain shape having a vertex at a substantially central portion in the front-rear direction. For this reason, the front surface of the terminal locking portion 36 has a tapered shape that is inclined downward (as viewed from the inside to the outside of the female housing 31) toward the front side, and the rear surface of the terminal locking portion 36 is directed to the rear side. The taper is inclined toward the lower side. When the female terminal 20 is inserted into the cavity 32 from the rear, the connecting tube portion 21 of the female terminal 20 comes into contact with the rear surface of the terminal locking portion 36 from the rear, and the connecting tube portion 21 is connected to the terminal locking portion 36. The lance 34 is elastically deformed downward. When the female terminal 20 reaches the proper position, the interference state between the connecting tube portion 21 and the terminal locking portion 36 is released, and the lance 34 is elastically restored, and a pair of lower ends of the connecting tube portion 21 at the rear edge of the connecting tube portion 21 is restored. The locked portion 26 is locked from the rear by the terminal locking portion 36, and the female terminal 20 is prevented from coming off in the female housing 31.

また、ランス３４の前端面は、雌ハウジング３１の底壁３１Ｂにおける外底面と略直交となる切り立った半挿入検知面３７とされている。
この半挿入検知面３７は、雌端子２０がキャビティ３２内において正規の位置よりも後方に配置された半挿入状態のときに、端子係止部３６と接続筒部２１とが干渉してランス３４が下方に弾性変形した状態となることで下方に突出し、雌ハウジング３１の底壁３１Ｂにおける外底面と略直交に交差した状態となるように設定されている。したがって、雌端子２０が半挿入状態で雌ハウジング３１をフード部５３内に挿入しようとすると、半挿入検知面３７がフード部５３の開口縁に当接して、フード部５３内への雌ハウジング３１の挿入が規制されるようになっている。つまり、雌端子２０が半挿入状態の雌コネクタ３０が雄コネクタ５０に嵌合されることを規制することができるようになっている。 Further, the front end surface of the lance 34 is a half-insertion detection surface 37 that is substantially perpendicular to the outer bottom surface of the bottom wall 31 </ b> B of the female housing 31.
When the female terminal 20 is in a half-inserted state in which the female terminal 20 is disposed behind the normal position in the cavity 32, the terminal insertion portion 36 and the connecting tube portion 21 interfere with each other to detect the lance 34. Is set to be in a state of projecting downward by being elastically deformed downward and intersecting the outer bottom surface of the bottom wall 31B of the female housing 31 substantially orthogonally. Therefore, when the female terminal 31 is to be inserted into the hood portion 53 with the female terminal 20 in the half-inserted state, the half-insertion detection surface 37 comes into contact with the opening edge of the hood portion 53, and the female housing 31 into the hood portion 53. Insertion is regulated. That is, the female connector 30 in which the female terminal 20 is half inserted can be restricted from being fitted into the male connector 50.

さて、ランス３４の前側下端部（端子係止部３６が設けられた位置の下側）には、図１に示すように、ランス３４が弾性変形しない自然状態において、雌ハウジング３１の底壁３１Ｂにおける外底面よりも下方に突出する突出部３８が設けられている。この突出部３８は、前後方向略中央部に頂点を有して前後方向に傾斜する山形状に形成されており、雌ハウジング３１がフード部５３内に嵌合されると、図２に示すように、フード部５３の下側内壁によって上方に押圧され、ランス３４を雌ハウジング３１の内側である上方に向かって弾性変形させるようになっている。 Now, at the front lower end of the lance 34 (below the position where the terminal locking portion 36 is provided), as shown in FIG. 1, the bottom wall 31B of the female housing 31 is in a natural state where the lance 34 is not elastically deformed. A projecting portion 38 projecting downward from the outer bottom surface is provided. The protruding portion 38 is formed in a mountain shape having a vertex at a substantially central portion in the front-rear direction and inclined in the front-rear direction. When the female housing 31 is fitted in the hood portion 53, as shown in FIG. The lance 34 is pressed upward by the lower inner wall of the hood 53 and elastically deforms the lance 34 upward, which is the inner side of the female housing 31.

一方、接続筒部２１の後端下縁における幅方向略中央部には、ランス３４が上方に弾性変形した際に、端子係止部３６の前面である押圧面３９によって斜め前上方に押圧される延出片２７が設けられている。
延出片２７は、接続筒部２１の後端下縁から斜め前上方に向かって折り返すように屈曲されて真っ直ぐ延出された形態をなしており、延出片２７の後端部に位置する屈曲された部分が押圧面３９によって押圧される被押圧部２８とされている。 On the other hand, in the substantially central portion in the width direction at the lower edge of the rear end of the connecting tube portion 21, when the lance 34 is elastically deformed upward, it is pressed obliquely forward and upward by the pressing surface 39 which is the front surface of the terminal locking portion 36. An extending piece 27 is provided.
The extending piece 27 is bent and straightly extended from the lower edge of the rear end of the connecting cylinder portion 21 toward the upper front obliquely, and is positioned at the rear end portion of the extending piece 27. The bent portion is a pressed portion 28 that is pressed by the pressing surface 39.

また、延出片２７における前端部は、延出片２７がランス３４の押圧面３９によって押圧された際に、接続筒部２１内に挿入された雄端子６０の雄側接続部６１を前側（雄コネクタ５０側）に向かって押し出し、雄端子６０を雄ハウジング５１の雄側ランス５５に押しつける押し出し部２９とされている。 Further, the front end portion of the extending piece 27 has a front side (on the male side connecting portion 61 of the male terminal 60 inserted into the connecting tube portion 21 when the extending piece 27 is pressed by the pressing surface 39 of the lance 34 ( The pushing portion 29 is pushed out toward the male connector 50 side and pushes the male terminal 60 against the male lance 55 of the male housing 51.

詳細には、押し出し部２９は、ランス３４が弾性変形しない自然状態では、接続筒部２１における底板２１Ａの高さ位置と弾性接触片２３における接点部２３Ａの高さ位置との間の高さ位置に配されている。そして、雌ハウジング３１がフード部５３内に挿入されて、フード部５３の下側内壁とランス３４の突出部３８とが干渉することによりランス３４が上方に弾性変形すると、延出片２７がランス３４の押圧面３９によって押圧され、僅かに斜め前上方に弾性変位する。そして、雌ハウジング３１と雄ハウジング５１のフード部５３とが正規に嵌合されると、図２に示すように、押し出し部２９の下面が接続筒部２１内に進入した雄側接続部６１の先端に当接し、雄側接続部６１を雄ハウジング５１側に弾性的に押し出す。すると、雄ハウジング５１内における雄端子６０が後方に移動して雄端子６０と雄側ランス５５との間のクリアランスＣが詰められ、雄端子６０が雄側ランス５５に押しつけられるようになっている。 Specifically, the pushing portion 29 is a height position between the height position of the bottom plate 21A in the connection cylinder portion 21 and the height position of the contact portion 23A in the elastic contact piece 23 in a natural state where the lance 34 is not elastically deformed. It is arranged in. Then, when the female housing 31 is inserted into the hood portion 53 and the lower inner wall of the hood portion 53 interferes with the protruding portion 38 of the lance 34, the lance 34 is elastically deformed upward, whereby the extending piece 27 is moved to the lance portion. It is pressed by the pressing surface 39 of 34 and is elastically displaced slightly diagonally forward and upward. Then, when the female housing 31 and the hood portion 53 of the male housing 51 are properly fitted, as shown in FIG. 2, the lower surface of the pushing portion 29 of the male side connecting portion 61 that has entered the connecting tube portion 21. It abuts on the tip and elastically pushes the male side connecting portion 61 toward the male housing 51 side. Then, the male terminal 60 in the male housing 51 moves rearward to close the clearance C between the male terminal 60 and the male lance 55, and the male terminal 60 is pressed against the male lance 55. .

すなわち、両ハウジング３１，５１が正規の嵌合状態に至ると、雄端子６０の雄側接続部６１と雌端子２０の延出片２７とが前後方向に当たり合うと共に、前後方向に当たり合った雄端子６０と雌端子２０とが、雄ハウジング５１の雄側ランス５５と雌ハウジング３１のランス３４とによって前後方向に挟持されるようになっている。
なお、延出片２７が前側に向かって弾性変形した変位量が、ランス孔６６の前側内壁と雄側ランス５５との間のクリアランスＣの寸法よりも大きい場合には、延出片２７が斜め上後方に弾性変形することにより、変位量とクリアランスＣとの差分を吸収することができるようになっている。 That is, when both the housings 31 and 51 are in the proper fitting state, the male side connection portion 61 of the male terminal 60 and the extending piece 27 of the female terminal 20 are in contact with each other in the front-rear direction, and the male terminal is in contact with the front-rear direction. 60 and the female terminal 20 are sandwiched between the male lance 55 of the male housing 51 and the lance 34 of the female housing 31 in the front-rear direction.
When the amount of displacement of the extended piece 27 elastically deformed toward the front side is larger than the dimension of the clearance C between the front inner wall of the lance hole 66 and the male lance 55, the extended piece 27 is inclined. By elastically deforming upward and backward, the difference between the displacement amount and the clearance C can be absorbed.

本実施形態のコネクタは、以上のような構成であって、続いてその作用を説明する。
まず、雌コネクタ３０の組み付け手順を説明する。
図４に示すように、電線Ｗに接続された雌端子２０と、雌ハウジング３１とを準備し、雌ハウジング３１のキャビティ３２に雌端子２０を後方から挿入する。
キャビティ３２に対して雌端子２０が半分程度挿入されると、接続筒部２１の前側下端部がランス３４の端子係止部３６に後方から当接して接続筒部２１が端子係止部３６に乗り上げ、ランス３４を下方に向かって弾性変形させる。そして、雌端子２０が正規の位置に至ると、接続筒部２１と端子係止部３６との当接状態が解除され、ランス３４が弾性復帰することで、接続筒部２１の一対の被係止部２６が端子係止部３６によって後方から係止される。これにより、雌端子２０が雌ハウジング３１内に抜け止めされ、雌コネクタ３０が完成する。 The connector of the present embodiment is configured as described above, and its operation will be described subsequently.
First, the assembly procedure of the female connector 30 will be described.
As shown in FIG. 4, the female terminal 20 connected to the electric wire W and the female housing 31 are prepared, and the female terminal 20 is inserted into the cavity 32 of the female housing 31 from the rear.
When about half of the female terminal 20 is inserted into the cavity 32, the lower end on the front side of the connecting tube portion 21 abuts against the terminal locking portion 36 of the lance 34 from the rear, so that the connecting tube portion 21 becomes the terminal locking portion 36. It rides and elastically deforms the lance 34 downward. When the female terminal 20 reaches the proper position, the contact state between the connecting tube portion 21 and the terminal locking portion 36 is released, and the lance 34 is elastically restored, so that the pair of engaged portions of the connecting tube portion 21 are released. The stop portion 26 is locked from behind by the terminal locking portion 36. Thereby, the female terminal 20 is prevented from coming off in the female housing 31, and the female connector 30 is completed.

次に、雄コネクタ５０の組み付け手順を説明する。
雄ハウジング５１と、電線Ｗに接続された雄端子６０とを準備し、雄側キャビティ５４内に雄端子６０を後方から挿入する。すると、挿入過程において、雄端子６０の本体部６２が雄側ランス５５に後方から当接して雄側ランス５５に乗り上げ、雄側ランス５５が斜め前方に変位するように弾性変形する。そして、雄端子６０が正規の位置まで挿入されると、雄側ランス５５と本体部６２との干渉状態が解除されて雄側ランス５５が弾性復帰することにより、雄側ランス５５が本体部６２のランス孔６６に嵌まり込んで後方から係止される。これにより、雄端子６０が雄ハウジング５１に抜け止めされ、雄コネクタ５０が完成する。また、この段階では、雄側ランス５５とランス孔６６の前側内壁との間には、雄側ランス５５が斜め前方に変位した分だけクリアランスＣを有した状態となっている。 Next, a procedure for assembling the male connector 50 will be described.
A male housing 51 and a male terminal 60 connected to the electric wire W are prepared, and the male terminal 60 is inserted into the male side cavity 54 from behind. Then, in the insertion process, the main body 62 of the male terminal 60 abuts on the male lance 55 from behind and rides on the male lance 55, and the male lance 55 is elastically deformed so as to be displaced obliquely forward. When the male terminal 60 is inserted to the proper position, the interference state between the male lance 55 and the main body 62 is released, and the male lance 55 is elastically restored, so that the male lance 55 is restored to the main body 62. It fits into the lance hole 66 and is locked from behind. Thereby, the male terminal 60 is prevented from being detached from the male housing 51, and the male connector 50 is completed. Further, at this stage, a clearance C is provided between the male lance 55 and the front inner wall of the lance hole 66 by the amount that the male lance 55 is displaced obliquely forward.

雌コネクタ３０と雄コネクタ５０とが完成したところで、図１に示すように、両コネクタ３０，５０を向かい合わせに配置し、雄ハウジング５１のフード部５３内に雌コネクタ３０を挿入して嵌合させる。
ここで、フード部５３に対して雌ハウジング３１が半分程度挿入されると、フード部５３の開口縁に雌ハウジング３１のランス３４における突出部３８が後方から当接して乗り上げ、フード部５３の下側内壁によって突出部３８が上方に押圧され、ランス３４が雌ハウジング３１の内側である上方に向かって弾性変形する。 When the female connector 30 and the male connector 50 are completed, as shown in FIG. 1, both the connectors 30 and 50 are arranged facing each other, and the female connector 30 is inserted into the hood portion 53 of the male housing 51 and fitted. Let
Here, when about half of the female housing 31 is inserted into the hood portion 53, the protruding portion 38 of the lance 34 of the female housing 31 comes into contact with the opening edge of the hood portion 53 from behind and rides up, and below the hood portion 53. The projecting portion 38 is pressed upward by the side inner wall, and the lance 34 is elastically deformed upward, which is the inner side of the female housing 31.

ところが、仮に雌端子２０がキャビティ３２に対して半挿入状態の場合には、端子係止部３６と接続筒部２１との当接状態が解除されず、ランス３４が下方に弾性変形した状態のままとなって、半挿入検知面３７が下方に突出した状態となる。つまり、フード部５３に雌ハウジング３１を挿入する際に、半挿入検知面３７がフード部５３の開口縁に当接し、雌端子２０が半挿入状態の雌コネクタ３０の挿入を規制することができる。すなわち、ランス３４を半挿入検知機構として兼用することで、雌端子２０が半挿入状態のままの雌コネクタ３０を雄コネクタ５０に嵌合させることを防ぐことができる。 However, if the female terminal 20 is in a half-inserted state with respect to the cavity 32, the contact state between the terminal locking portion 36 and the connecting tube portion 21 is not released, and the lance 34 is elastically deformed downward. As it is, the half-insertion detection surface 37 protrudes downward. That is, when the female housing 31 is inserted into the hood portion 53, the half-insertion detection surface 37 abuts on the opening edge of the hood portion 53, and the insertion of the female connector 30 in which the female terminal 20 is in the half-inserted state can be restricted. . That is, by using the lance 34 as a half-insertion detection mechanism, it is possible to prevent the female connector 30 with the female terminal 20 in the half-inserted state from being fitted to the male connector 50.

また、フード部５３に対して雌ハウジング３１が嵌合され、ランス３４が上方に向かって弾性変形すると、端子係止部３６の押圧面３９が延出片２７の被押圧部２８を斜め下後方から押圧し、延出片２７が斜め前上方に向かって僅かに弾性変形する。 Further, when the female housing 31 is fitted to the hood portion 53 and the lance 34 is elastically deformed upward, the pressing surface 39 of the terminal locking portion 36 causes the pressed portion 28 of the extending piece 27 to move obliquely downward and rearward. The extension piece 27 is slightly elastically deformed diagonally forward and upward.

この状態のまま、更に雄ハウジング５１と雌ハウジング３１とを嵌合させ、両ハウジング３１，５１が正規の嵌合状態に至ると、図２に示すように、雄端子６０の雄側接続部６１が雌ハウジング３１の端子挿通孔３３を通して雌端子２０の接続筒部２１内に進入し、接続筒部２１の弾性接触片２３と雄側接続部６１とが電気的に接続される。
また、これと同時に、延出片２７の押し出し部２９が雄側接続部６１の先端に当接し、押し出し部２９が雄側接続部６１を雄ハウジング５１側に弾性的に押圧する。すると、雄ハウジング５１内における雄端子６０が後方に移動し、本体部６２におけるランス孔６６の前側内壁と雄側ランス５５との間のクリアランスＣが詰められて、雄端子６０が雄側ランス５５に押しつけられる。 In this state, when the male housing 51 and the female housing 31 are further fitted to each other, and both the housings 31 and 51 reach the proper fitting state, as shown in FIG. Enters the connecting tube portion 21 of the female terminal 20 through the terminal insertion hole 33 of the female housing 31, and the elastic contact piece 23 of the connecting tube portion 21 and the male side connecting portion 61 are electrically connected.
At the same time, the pushing portion 29 of the extending piece 27 comes into contact with the tip of the male side connecting portion 61, and the pushing portion 29 elastically presses the male side connecting portion 61 toward the male housing 51 side. Then, the male terminal 60 in the male housing 51 moves rearward, the clearance C between the front inner wall of the lance hole 66 in the main body 62 and the male lance 55 is filled, and the male terminal 60 is connected to the male lance 55. Pressed against.

これにより、前後方向に当たり合った雄端子６０と雌端子２０とが、雄ハウジング５１の雄側ランス５５と雌ハウジング３１のランス３４とによって前後方向に挟持され、両ハウジング３１，５１内において雄端子６０および雌端子２０が前後方向にがたつくことを防ぐことができる。ひいては、接続筒部２１の弾性接触片２３と雄側接続部６１との間において微摺動摩耗が生じることを抑制し、端子２０，６０間の接触抵抗の増加を抑制することができる。 As a result, the male terminal 60 and the female terminal 20 that have come into contact with each other in the front-rear direction are sandwiched in the front-rear direction by the male-side lance 55 of the male housing 51 and the lance 34 of the female housing 31. 60 and the female terminal 20 can be prevented from rattling in the front-rear direction. As a result, it is possible to suppress the occurrence of fine sliding wear between the elastic contact piece 23 of the connection cylinder portion 21 and the male side connection portion 61, and to suppress an increase in contact resistance between the terminals 20 and 60.

また、本実施形態によると、延出片２７の前端部が雄側接続部６１を押圧する押し出し部２９とされ、延出片２７の後端部がランス３４の押圧面３９に押圧される被押圧部２８とされているから、ランス３４によって押圧される押圧力を、延出片２７のみを介して雄側接続部６１に伝えることができる。すなわち、例えば、接続筒部の上下に押し出し部と被押圧部とが分かれて形成される場合に比べて、押圧力を雄側接続部６１に確実に伝えることができると共に、接続筒部２１の構造を簡素化することができる。 Further, according to the present embodiment, the front end portion of the extending piece 27 is the pushing portion 29 that presses the male side connecting portion 61, and the rear end portion of the extending piece 27 is pressed against the pressing surface 39 of the lance 34. Since the pressing portion 28 is used, the pressing force pressed by the lance 34 can be transmitted to the male side connecting portion 61 only through the extending piece 27. That is, for example, the pressing force can be reliably transmitted to the male side connecting portion 61 as compared with the case where the extruded portion and the pressed portion are formed separately above and below the connecting tube portion, and the connecting tube portion 21 The structure can be simplified.

また、フード部５３への雌ハウジング３１の挿入過程において、延出片２７の被押圧部２８を押圧するランス３４の押圧面３９がテーパ状に形成されているから、押圧面３９によって接続筒部２１を雄ハウジング５１側に向かって滑らかに押し出すことができる。つまり、フード部５３に対して雌ハウジング３１を円滑に挿入することができ、作業性・操作感に優れる。
また、延出片２７の後端部に位置する屈曲された部分を被押圧部２８としているから、例えば、被押圧部が角部として形成される場合に比べて、押圧面３９が被押圧部２８に削られて損傷することを抑制することができる。 Further, in the process of inserting the female housing 31 into the hood portion 53, the pressing surface 39 of the lance 34 that presses the pressed portion 28 of the extending piece 27 is formed in a tapered shape. 21 can be smoothly pushed out toward the male housing 51 side. That is, the female housing 31 can be smoothly inserted into the hood portion 53, and the workability and operational feeling are excellent.
Moreover, since the bent part located in the rear-end part of the extension piece 27 is made into the to-be-pressed part 28, compared with the case where a to-be-pressed part is formed as a corner | angular part, for example, the pressing surface 39 is a to-be-pressed part. It can suppress that it is cut | disconnected by 28 and is damaged.

以上のように、本実施形態では、雌ハウジング３１と雄ハウジング５１のフード部５３とを嵌合させるだけで、前後方向に当たり合った雄端子６０と雌端子２０とを、雄ハウジング５１の雄側ランス５５と雌ハウジング３１のランス３４とによって前後方向に挟持することができる。これにより、両ハウジング３１，５１内において雄端子６０および雌端子２０が前後方向にがたつくことを防ぐことができ、接続筒部２１の弾性接触片２３と雄側接続部６１との間において微摺動摩耗が生じることを抑制することができる。 As described above, in the present embodiment, the male terminal 60 and the female terminal 20 that are in contact with each other in the front-rear direction can be connected to the male side of the male housing 51 only by fitting the female housing 31 and the hood portion 53 of the male housing 51. The lance 55 and the lance 34 of the female housing 31 can be held in the front-rear direction. Thereby, it is possible to prevent the male terminal 60 and the female terminal 20 from shaking in the front-rear direction in both the housings 31, 51, and finely slide between the elastic contact piece 23 of the connection tube portion 21 and the male-side connection portion 61. The occurrence of dynamic wear can be suppressed.

また、雌端子２０の半挿入状態を検知すると共に、雌端子２０を後側から係止するランス３４を、雌端子２０の延出片２７を押圧する押圧部として兼用することができるから、機能毎に部材を個別に設ける場合に比べて、雌コネクタ３０の構造を格段に簡素化することができる。これにより、雌コネクタ３０と共に、雄コネクタ５０が大型化することを抑制することができる。 In addition, the half-insertion state of the female terminal 20 can be detected, and the lance 34 that locks the female terminal 20 from the rear side can also be used as a pressing portion that presses the extension piece 27 of the female terminal 20. The structure of the female connector 30 can be greatly simplified as compared with the case where the members are provided individually for each time. Thereby, it can suppress that the male connector 50 enlarges with the female connector 30. FIG.

ところで、例えば、雌ハウジングのランスを上方に向かって変位させる手段としては、フード部内に突起を設け、フード部と雌ハウジングとが正規の嵌合状態に至った際に、突起によってランスを上方に弾性変形させるといった方法も考えられる。しかしながら、このような構成によると、フード部に突起を設けるための型抜き孔を設ける必要ある。ところが、本実施形態によると、フード部５３の下側内壁によって押圧される突出部３８を、ランス３４の前側下端部に設けるだけで、ランス３４を上方に向かって変位させることができる。すなわち、雄コネクタ５０の構成を変更することなく、ランス３４を上方に向かって弾性変形させることができる。 By the way, for example, as a means for displacing the lance of the female housing upward, a protrusion is provided in the hood portion, and when the hood portion and the female housing reach a proper fitting state, the lance is moved upward by the protrusion. A method of elastic deformation is also conceivable. However, according to such a configuration, it is necessary to provide a die-cutting hole for providing a protrusion on the hood portion. However, according to the present embodiment, the lance 34 can be displaced upward only by providing the protruding portion 38 pressed by the lower inner wall of the hood portion 53 at the front lower end portion of the lance 34. That is, the lance 34 can be elastically deformed upward without changing the configuration of the male connector 50.

また、例えば、延出片の後端部である被押圧部のみを端子係止部によって後側から係止することで、雌端子を雌ハウジング内に抜け止めする方法も考えられるが、電線が引っ張られるなどして雌端子が後側に強く引っ張られると、延出片が前側に向かって過度撓みすることで、延出片が破損する虞がある。ところが本実施形態によると、雌端子２０が後側に強く引っ張られた際には、延出片２７の両側に設けられた一対の被係止部２６が端子係止部３６によって後側から係止されるから、延出片２７を破損させることなく、雌端子２０を確実に抜け止めすることができる。 In addition, for example, a method of locking the female terminal into the female housing by locking only the pressed portion that is the rear end portion of the extending piece from the rear side by the terminal locking portion is conceivable. When the female terminal is strongly pulled rearward by being pulled or the like, the extended piece may be excessively bent toward the front side, and the extended piece may be damaged. However, according to the present embodiment, when the female terminal 20 is pulled strongly to the rear side, the pair of locked portions 26 provided on both sides of the extension piece 27 are engaged from the rear side by the terminal locking portions 36. Therefore, the female terminal 20 can be reliably prevented from coming off without damaging the extending piece 27.

＜実施形態２＞
次に、本発明の実施形態２について図６を参照して説明する。
実施形態２の雌コネクタ１３０は、実施形態１における延出片２７の押し出し部２９の形状を変更したものであって、実施形態１と共通する構成、作用、および効果については重複するため、その説明を省略する。また、実施形態１と同じ構成については同一の符号を用いるものとする。 <Embodiment 2>
Next, Embodiment 2 of the present invention will be described with reference to FIG.
The female connector 130 of the second embodiment is obtained by changing the shape of the pushing portion 29 of the extending piece 27 in the first embodiment, and the configuration, operation, and effect common to the first embodiment are duplicated. Description is omitted. The same reference numerals are used for the same configurations as those in the first embodiment.

実施形態２の延出片１２７における押し出し部１２９は、延出片１２７の前端部を上方に向かって屈曲させることにより形成されており、押し出し部１２９の前面が雄端子６０の挿入方向である前後方向と略直交に交差した状態となっている。
