On the other hand, the terminal fitting is provided with a pair of stabilizers projecting downward from the lower surface thereof. When the terminal fitting is properly inserted into the cavity, the stabilizer is disposed in the vicinity of both side surfaces in the width direction of the lance.
JP-A-8-222321

ところで、ランスは、スタビライザと幅方向に関して非干渉となるべく両スタビライザの内側領域に配されるから、全体的に幅狭となる傾向にある。したがって、端子金具が接続した電線を後方へ強く引張ったりすると、ランスがその強度不足に起因して座屈する懸念があった。   By the way, since the lance is arranged in the inner region of both stabilizers so as to be non-interfering with the stabilizer in the width direction, it tends to be narrow as a whole. Therefore, when the electric wire connected with the terminal fitting is pulled backward strongly, there is a concern that the lance buckles due to insufficient strength.

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、ランスが座屈するのを防止することを目的とする。   The present invention has been completed based on the above circumstances, and an object thereof is to prevent the lance from buckling.

上記の目的を達成するための手段として、請求項１の発明は、端子金具を挿入可能なキャビティが形成されたハウジングを備え、このハウジングにおける前記キャビティの内側面に、前記端子金具に対して弾性的に係止可能なランスが形成されているコネクタにおいて、前記端子金具には、同端子金具の挿入動作を案内するためのスタビライザが突出して形成され、前記端子金具が前記キャビティ内に挿入された後には、前記スタビライザが前記ランスの幅方向外側に配されるものであって、前記ハウジングにおける前記キャビティの内側面には、前記ランスのうちの少なくとも根元部分に沿って一体的に延出するランス補強部が設けられていることに特徴を有する。   As a means for achieving the above object, the invention of claim 1 includes a housing in which a cavity into which a terminal fitting can be inserted is formed, and an inner surface of the cavity in the housing is elastic with respect to the terminal fitting. In the connector in which a lance that can be locked is formed, a stabilizer for guiding the insertion operation of the terminal fitting is formed on the terminal fitting so that the terminal fitting is inserted into the cavity. Later, the stabilizer is disposed on the outer side in the width direction of the lance, and the inner surface of the cavity in the housing has a lance that extends integrally along at least a root portion of the lance. It is characterized in that a reinforcing part is provided.

請求項２の発明は、請求項１に記載のものにおいて、前記ランス補強部は、前記端子金具が前記キャビティ内に挿入された後、前記スタビライザを支持可能に配置されているところに特徴を有する。
請求項３の発明は、請求項１または請求項２に記載のものにおいて、前記ランス補強部が前記ランスの幅方向両側面に一対設けられていることに特徴を有する。 The invention of claim 2 is characterized in that, in the invention of claim 1, the lance reinforcing portion is disposed so as to support the stabilizer after the terminal fitting is inserted into the cavity. .
The invention of claim 3 is characterized in that, in the invention of claim 1 or 2, a pair of the lance reinforcing portions are provided on both side surfaces in the width direction of the lance.

＜請求項１の発明＞
キャビティ内に端子金具を挿入すると、端子金具はスタビライザによって正規挿入位置に案内され、ランスにより弾性的に係止される。ハウジングにおけるキャビティの内側面には、ランスのうちの少なくとも根元部分に沿って一体的に延出するランス補強部が設けられているから、ランスの強度が増し、抜き方向の引張力に抗してランスが座屈するのを防止できる。 <Invention of Claim 1>
When the terminal fitting is inserted into the cavity, the terminal fitting is guided to the normal insertion position by the stabilizer and is elastically locked by the lance. The inner surface of the cavity in the housing is provided with a lance reinforcing portion that extends integrally along at least the root portion of the lance, so that the strength of the lance is increased and the tensile force in the pulling direction is resisted. It is possible to prevent the lance from buckling.

＜請求項２の発明＞
ランス補強部は、端子金具がキャビティ内に挿入された後、スタビライザを支持可能に配置されるから、スタビライザとランス補強部との隙間が詰められて端子金具のがた止めがなされる。
＜請求項３の発明＞
ランス補強部がランスの幅方向両側面に沿って一対設けられているから、ランスの強度がより一層高められる。 <Invention of Claim 2>
Since the lance reinforcing portion is disposed so that the stabilizer can be supported after the terminal fitting is inserted into the cavity, the gap between the stabilizer and the lance reinforcing portion is filled to prevent the terminal fitting from being rattled.
<Invention of Claim 3>
Since a pair of lance reinforcing portions are provided along both side surfaces in the width direction of the lance, the strength of the lance is further increased.

＜実施形態＞
本発明の実施形態を図１ないし図４によって説明する。この実施形態に係るコネクタは、雄コネクタと嵌合可能な雌コネクタであって、雌端子金具３０を収容可能なハウジング１０を備える。なお、以下の説明においては、雄コネクタに対する嵌合面側を前方とし、上下方向については図１を基準とする。 <Embodiment>
An embodiment of the present invention will be described with reference to FIGS. The connector according to this embodiment is a female connector that can be fitted to a male connector, and includes a housing 10 that can accommodate a female terminal fitting 30. In the following description, the fitting surface side with respect to the male connector is the front, and the vertical direction is based on FIG.

雌端子金具３０は、金属板材に折り曲げ加工等を施すことで所定の形状に成形され、図２に示すように、箱形の本体部３１とその後方に連成されて電線５０にかしめ付けられるバレル部３２とからなる。バレル部３２はさらに電線５０の芯線５１にかしめ接続されるワイヤーバレル３２Ａと電線５０の被覆５２にかしめ接続されるインシュレーションバレル３２Ｂとからなる。   The female terminal fitting 30 is formed into a predetermined shape by bending a metal plate material or the like, and as shown in FIG. It consists of a barrel part 32. The barrel portion 32 further includes a wire barrel 32A that is caulked and connected to the core wire 51 of the electric wire 50 and an insulation barrel 32B that is caulked and connected to the sheath 52 of the electric wire 50.

本体部３１は、図１に示すように、底壁３１Ａとその両側端から立ち上げられた左右の側壁３１Ｂとこのうちの一方の側壁３１Ｂから他方の側壁３１Ｂにかけて架け渡された天井壁３１Ｅとからなる。本体部３１の内部には底壁３１Ａの前端から後方へ向けて折り返し状に延出する弾性接触片３３が撓み可能に形成され、この弾性接触片３３の上面頂上付近には接点部３４が突設されている。天井壁３１Ｅには内側に向けて周囲から台形状に突き出る受け部３５が形成され、この受け部３５と接点部３４との間に雄端子金具のタブ（図示せず）が弾性的に挟み込まれることで雌雄の両端子金具の導通がとられる。天井壁３１Ｅの一側端部（図１に示す左側端部）には、板厚方向に二重に折り重ねられることで一段高くなった突部３６が設けられている。この突部３６は、後述するハウジング１０のキャビティ１１の内側面に形成された挿通溝１２に嵌入可能とされる。   As shown in FIG. 1, the main body 31 includes a bottom wall 31A, left and right side walls 31B raised from both side ends thereof, and a ceiling wall 31E extending from one side wall 31B to the other side wall 31B. Consists of. An elastic contact piece 33 extending in a folded shape from the front end of the bottom wall 31 </ b> A to the back is formed inside the main body portion 31 so as to be able to bend, and a contact portion 34 projects near the top of the upper surface of the elastic contact piece 33. It is installed. The ceiling wall 31E is formed with a receiving portion 35 protruding in the trapezoidal shape from the periphery toward the inside, and a tab (not shown) of a male terminal fitting is elastically sandwiched between the receiving portion 35 and the contact portion 34. Thus, the male and female terminal fittings are connected. At one end (the left end shown in FIG. 1) of the ceiling wall 31E, there is provided a protrusion 36 that is raised by double folding in the thickness direction. The protrusion 36 can be inserted into the insertion groove 12 formed on the inner surface of the cavity 11 of the housing 10 to be described later.

本体部３１の底壁３１Ａには、左右一対のスタビライザ３７が下方へ突出して形成されている。両スタビライザ３７は底壁３１Ａの一部を切り起こして形成され、これに伴って底壁３１Ａにおける両スタビライザ３７の間には窓孔（図示せず）が開口して形成される。底壁３１Ａにおける窓孔の孔縁には、後述するランス１３が弾性的に係止可能とされる。   A pair of left and right stabilizers 37 are formed on the bottom wall 31 </ b> A of the main body 31 so as to protrude downward. Both stabilizers 37 are formed by cutting and raising a part of the bottom wall 31A. Along with this, a window hole (not shown) is formed between the stabilizers 37 on the bottom wall 31A. A lance 13, which will be described later, can be elastically locked to a hole edge of the window hole in the bottom wall 31A.

両スタビライザ３７は、底壁３１Ａの幅方向両側端から幅方向中央側へ寄った位置に対称配置されている。ここで、両スタビライザ３７を底壁３１Ａの幅方向両側端に配する場合には、それに伴って窓孔の開口径が大きくなるから、雌端子金具３０の強度を充分に確保し難くなる。しかし、このように両スタビライザ３７を底壁３１Ａの幅方向中央側へ寄せて配すれば、窓孔の開口径をさほど大きくしなくて済むから、雌端子金具３０の強度を充分に維持できる。   Both the stabilizers 37 are symmetrically arranged at positions that approach the center in the width direction from both ends in the width direction of the bottom wall 31A. Here, when both the stabilizers 37 are disposed on both ends in the width direction of the bottom wall 31A, the opening diameter of the window hole is increased accordingly, so that it is difficult to sufficiently secure the strength of the female terminal fitting 30. However, if both stabilizers 37 are arranged close to the center in the width direction of the bottom wall 31A in this way, the opening diameter of the window hole does not have to be increased so much that the strength of the female terminal fitting 30 can be sufficiently maintained.

ハウジング１０は、合成樹脂材により一体形成され、雌端子金具３０を挿入可能なキャビティ１１が前後方向に貫通して形成されている。キャビティ１１の内側面の上壁一側端部には挿通溝１２が形成され、ここに雌端子金具３０の突部３６を嵌め入れることで雌端子金具３０が軸周りに誤った姿勢で挿入されるのを防止できるようになっている。   The housing 10 is integrally formed of a synthetic resin material, and a cavity 11 into which the female terminal fitting 30 can be inserted is formed so as to penetrate in the front-rear direction. An insertion groove 12 is formed at one end of the inner wall of the cavity 11 on the inner wall, and the female terminal fitting 30 is inserted in an incorrect posture around the axis by fitting the protrusion 36 of the female terminal fitting 30 therein. Can be prevented.

ハウジング１０におけるキャビティ１１の内側面には、上下方向に撓み変形可能なランス１３が延出して形成されている。雌端子金具３０がキャビティ１１内に挿入されると、雌端子金具３０とランス１３とが干渉してランス１３が下方（後述する撓み空間１５側）へ撓み変形される。その後、雌端子金具３０が正規挿入されると、ランス１３が弾性復帰して雌端子金具３０を抜け止め状態で係止するようになっている。   On the inner surface of the cavity 11 in the housing 10, a lance 13 that can be bent and deformed in the vertical direction is extended and formed. When the female terminal fitting 30 is inserted into the cavity 11, the female terminal fitting 30 and the lance 13 interfere with each other, and the lance 13 is bent and deformed downward (toward a bending space 15 described later). Thereafter, when the female terminal fitting 30 is properly inserted, the lance 13 is elastically restored to lock the female terminal fitting 30 in a retaining state.

ランス１３は、全長に亘ってほぼ同幅をもって構成され、その幅寸法は両スタビライザ３７間の距離よりも僅かに小さく設定されている。詳しくはランス１３は、図４に示すように、キャビティ１１の内側面の下壁１１Ａにその根元部１３Ａを一体的に接続させつつ前方へ向けて延出する片持ち状のアーム部１３Ｂと、そのアーム部１３Ｂの延出端側にて上方に突き出る係止部１３Ｅとからなる。係止部１３Ｅは、その前面がほぼ鉛直に切り立つ係止面１３Ｆとされ、かつその後面が前方へ向けて昇り勾配となるテーパ面１３Ｇとされる。係止面１３Ｅは雌端子金具３０が正規挿入されたときに窓孔の孔縁に係止可能とされ、テーパ面１３Ｇは雌端子金具３０の挿入途中で雌端子金具３０の前端と摺接可能とされる。アーム部１３Ｂのうち係止部１３Ｅより前方領域は、前端に行くにつれ下り勾配となる案内斜面１３Ｈとされ、ここに係止解除用の治具（図示せず）が摺接してランス１３の係止解除動作が案内可能とされる。   The lance 13 is configured with substantially the same width over the entire length, and the width dimension is set to be slightly smaller than the distance between the stabilizers 37. Specifically, as shown in FIG. 4, the lance 13 has a cantilevered arm portion 13 </ b> B extending forward while integrally connecting the base portion 13 </ b> A to the lower wall 11 </ b> A of the inner surface of the cavity 11, The arm portion 13B includes a locking portion 13E protruding upward on the extending end side. The locking portion 13E has a locking surface 13F whose front surface is substantially vertically cut, and a rear surface of the locking portion 13E is a tapered surface 13G that is inclined upward. The locking surface 13E can be locked to the hole edge of the window hole when the female terminal fitting 30 is properly inserted, and the tapered surface 13G can be slidably contacted with the front end of the female terminal fitting 30 while the female terminal fitting 30 is being inserted. It is said. A region in front of the locking portion 13E of the arm portion 13B is a guide slope 13H that becomes a downward slope as it goes to the front end, and a locking release jig (not shown) is brought into sliding contact therewith to engage the lance 13. The stop release operation can be guided.

アーム部１３Ｂの下面には、このアーム部１３Ｂの成形に伴いハウジング１０の前面に開口する撓み空間１５が形成されている。撓み空間１５は、ハウジング１０の前面に対向する垂直壁１６とアーム部１３Ｂの下面に平行する水平壁１７とにより区画されている。ランス１３の根元部１３Ａは、その後端位置が撓み空間１５よりも後退した位置に設定され、その後端面に雌端子金具３０の挿入動作を案内するための案内面１３Ｋを有している。   A bending space 15 that opens to the front surface of the housing 10 is formed on the lower surface of the arm portion 13B as the arm portion 13B is formed. The bending space 15 is defined by a vertical wall 16 facing the front surface of the housing 10 and a horizontal wall 17 parallel to the lower surface of the arm portion 13B. The root portion 13 </ b> A of the lance 13 is set at a position where the rear end position is retracted from the bending space 15, and has a guide surface 13 </ b> K for guiding the insertion operation of the female terminal fitting 30 on the rear end surface.

また、ハウジング１０におけるキャビティ１１の内側面の下壁１１Ａにおける開口両側端部には、図３に示すように、左右一対の端子受け台１８が形成されている。雌端子金具３０がキャビティ１１内に正規挿入されると、本体部３１が両端子受け台１８により下支えされ、もって雌端子金具３０が前のめりに倒れないようになっている。   Further, as shown in FIG. 3, a pair of left and right terminal cradles 18 are formed at both ends of the opening in the lower wall 11A of the inner side surface of the cavity 11 in the housing 10. When the female terminal fitting 30 is properly inserted into the cavity 11, the main body 31 is supported by the both terminal receiving bases 18 so that the female terminal fitting 30 does not fall forward.

ハウジング１０の内側面の下壁には、アーム部１３Ｂの長さ方向に沿ってランス補強部１９が形成されている。ランス補強部１９は、アーム部１３Ｂの両側端面に対応して左右一対が対称配置され、その根元部を垂直壁１６に一体的に接続させるとともにその内側面をアーム部１３Ｂの両側端面に一体的に接続させ、かつ、その前端位置をアーム部１３Ｂの前端位置に揃えて構成される。また、ランス補強部１９は、全体として薄肉板状をなし、アーム部１３Ｂの厚み方向に関する下半領域に接続され、両スタビライザ３７の進行路から外れた位置に設定されている。   A lance reinforcing portion 19 is formed on the lower wall of the inner side surface of the housing 10 along the length direction of the arm portion 13B. A pair of left and right lance reinforcing portions 19 are symmetrically arranged corresponding to both side end surfaces of the arm portion 13B, and the base portion thereof is integrally connected to the vertical wall 16 and the inner side surface thereof is integrated with both side end surfaces of the arm portion 13B. And the front end position thereof is aligned with the front end position of the arm portion 13B. Further, the lance reinforcing portion 19 has a thin plate shape as a whole, is connected to a lower half region in the thickness direction of the arm portion 13B, and is set at a position away from the traveling path of both stabilizers 37.

ここで、両スタビライザ３７は、雌端子金具３０の挿入途中で、ランス１３の幅方向両側外方で、かつランス補強部１９上に位置し、ランス補強部１９との干渉を回避可能とされる。そして、両スタビライザ３７は、雌端子金具３０の挿入後においても、ランス補強部１９上に位置し、このランス補強部１９によって下支え可能とされる。   Here, both stabilizers 37 are located on both sides of the lance 13 in the width direction and on the lance reinforcing portion 19 while the female terminal fitting 30 is being inserted, so that interference with the lance reinforcing portion 19 can be avoided. . Both stabilizers 37 are located on the lance reinforcing portion 19 and can be supported by the lance reinforcing portion 19 even after the female terminal fitting 30 is inserted.

次に本実施形態の作用効果を説明する。まず、電線５０の端末に雌端子金具３０を接続し、その状態で挿通溝１２に突部３６を嵌め入れつつ、後方からキャビティ１１内に雌端子金具３０を挿入する。その挿入途上では両スタビライザ３７がランス１３の幅方向両側面に沿うとともにランス補強部１９の上面に沿って移動し、もって雌端子金具３０の挿入姿勢が安定化する。ランス１３は、雌端子金具３０と干渉して下方（撓み空間１５側）へ撓み変形されるが、雌端子金具３０が正規挿入されると、弾性復帰してその係止部１３Ｅが雌端子金具３０の窓孔に嵌め入れられるとともに、窓孔の前縁に係止部１３Ｅの係止面が係止可能とされる。こうして正規挿入位置に至った雌端子金具３０は、端子受け台１８に載置されるとともにランス補強部１９に支持可能とされ、もって軸ずれを起こすことなく雄端子金具のタブを受け入れ可能に待機される。   Next, the effect of this embodiment is demonstrated. First, the female terminal fitting 30 is connected to the end of the electric wire 50, and the female terminal fitting 30 is inserted into the cavity 11 from the rear while fitting the protrusion 36 into the insertion groove 12 in this state. During the insertion process, both stabilizers 37 move along both side surfaces of the lance 13 in the width direction and along the upper surface of the lance reinforcing portion 19, thereby stabilizing the insertion posture of the female terminal fitting 30. The lance 13 interferes with the female terminal fitting 30 and bends and deforms downward (toward the bending space 15). However, when the female terminal fitting 30 is properly inserted, the lance 13 is elastically restored and the locking portion 13E becomes the female terminal fitting. In addition to being fitted into the 30 window holes, the locking surface of the locking portion 13E can be locked to the front edge of the window hole. The female terminal fitting 30 that has reached the normal insertion position in this manner is placed on the terminal cradle 18 and can be supported by the lance reinforcing portion 19 so that the male terminal fitting tab can be received without causing an axis shift. Is done.

ところで、電線５０を引張る等して雌端子金具３０に引き抜き方向の力を付与すると、これに連られてランス１３の係止部１３Ｅが後方へ引張られてランス１３の根元部分に圧縮方向の力が作用するが、本実施形態によれば、ランス補強部１９によってランス１３全体の強度が高められているから、かかる場合においても、ランス１３が座屈する事態を回避できる。   By the way, when a force in the pulling direction is applied to the female terminal fitting 30 by pulling the electric wire 50 or the like, the engaging portion 13E of the lance 13 is pulled rearward in conjunction with this, and a force in the compressing direction is applied to the root portion of the lance 13. However, according to this embodiment, since the strength of the entire lance 13 is enhanced by the lance reinforcing portion 19, even in such a case, the situation where the lance 13 is buckled can be avoided.

また、ランス補強部１９が両スタビライザ３７と対応する位置に一対設けられ、雌端子金具３０がキャビティ１１内に挿入された両スタビライザ３７を下支え可能とされるから、両スタビライザ３７とランス補強部１９との隙間が詰められて雌端子金具３０のがた止めが保障される。
さらに、ランス補強部１９がランス１３の幅方向両側面に沿って一対設けられているから、ランス１３の強度がより一層高められる。 In addition, a pair of lance reinforcing portions 19 are provided at positions corresponding to both the stabilizers 37, and the female terminal fitting 30 can support both the stabilizers 37 inserted into the cavity 11, so that both the stabilizers 37 and the lance reinforcing portion 19 are supported. The gap between the female terminal fitting 30 and the female terminal fitting 30 is secured.
Furthermore, since the lance reinforcement part 19 is provided in a pair along both sides of the lance 13 in the width direction, the strength of the lance 13 is further enhanced.
