【考案の詳細な説明】 本考案はコネクタハウジングに関し、雌端子を内挿する
端子収容室に改良を施して相手側の雄端子を常に整合す

したものである。[Detailed description of the invention] The present invention relates to a connector housing, and improves the terminal accommodating chamber into which the female terminal is inserted, so that the mating male terminal is always inserted and aligned, thereby preventing deformation and damage of the female terminal. It was designed to do so.

、従来の此種コネクタハウジングは、第１図に示すよう
に、端子収容室ａの前端における開口寸法ｔが雄端子Ａ
よりも大きく設計されている。, in the conventional connector housing of this type, as shown in FIG.
It is designed to be larger than the

。That is, a stopper wall e+c' is provided protruding from both the upper and lower walls S and b' of the accommodation chamber a that are opposed to each other, and is configured to prevent the inserted female terminal B from coming out from the front, but the stopper wall CvC' The dimension t between them is much larger than the thickness t of the male terminal A.

そのため、雄端子Ａの嵌挿に際しては、二点鎖線に示す

理に挿圧することが可能であり、雌端子Ｂの変形、破損
のみならずノ・ウジング自体を損傷する危険があり、か
つ雌端子Ｂが一旦変形すると、以後の使用が出来なくな
るという不都合があった。Therefore, when inserting the male terminal A, it is possible to forcefully insert the male terminal A in a misaligned state inclined to the axis of the female terminal B, as shown by the two-dot chain line, and the female terminal B will only be deformed and damaged. There was a risk of damaging the housing itself, and once the female terminal B was deformed, it could no longer be used.

本考案は以上に鑑みてなされたもので、雄端子が雌端子
に対して多少傾斜している場合でもこれを矯正し、整合
状態で嵌挿されるようにし、その変形や破損を防止し得
るコネクタノ・ウジングを提供せんとするものである。The present invention has been devised in view of the above, and is a connector that corrects even if the male terminal is slightly inclined with respect to the female terminal, allows the male terminal to be inserted in an aligned state, and prevents deformation and damage. The aim is to provide a sense of comfort.

以下１本考案の一実施例を図面と共に説明する。An embodiment of the present invention will be described below with reference to the drawings.

第２図において、Ｆは内部を端子収容室１としたコネク
タハウジング、Ｔは雌端子を示す。In FIG. 2, F indicates a connector housing with a terminal accommodating chamber 1 inside, and T indicates a female terminal.

端子収容室１において、その上壁２の後半部には先端に
係止突起５を有して前方にのびる可撓アーム４が突設さ
れ、また上壁２の前方開口端にはストッパ壁６が突設さ
れている。In the terminal accommodating chamber 1, a flexible arm 4 having a locking protrusion 5 at its tip and extending forward is provided in the rear half of the upper wall 2, and a stopper wall 6 is provided at the front open end of the upper wall 2. is installed protrudingly.

以上は従来と同様の構成であるが、本考案にあっては、
収容室１の底壁３に、前記ストッパ壁６と対向して可撓
性のストッパ壁７が設けである。The above is the same configuration as the conventional one, but in this invention,
A flexible stopper wall 7 is provided on the bottom wall 3 of the storage chamber 1, facing the stopper wall 6.

このストッパ壁７は、端子収容室１の内部に向けて断面
は文Ｕ字状で、その基部８を支点にして弾性的に変位す
る如く構成され、またストッパ壁７の上面と前記ストッ
パ壁６間の開口寸法りは前記雄端子Ａの厚さｔよりも充
分小さくとる。This stopper wall 7 has a U-shaped cross section toward the inside of the terminal storage chamber 1, and is configured to be elastically displaced about its base 8 as a fulcrum. The opening size between the two is set to be sufficiently smaller than the thickness t of the male terminal A.

一方、雌端子Ｔは、基板部１０の前部に雄端子に対する
電気接触部Ｔｌ、後部に電線接続部Ｔ２を有して構成さ
れ、電線接続部Ｔ２には導体加締片１１及び絶縁体加締
片１２によって電線Ｗが圧着されている。On the other hand, the female terminal T has an electrical contact part Tl for the male terminal at the front part of the board part 10, and an electric wire connection part T2 at the rear part, and the electric wire connection part T2 has a conductor clamping piece 11 and an insulator clamping part T2. The electric wire W is crimped by the clamping piece 12.

また、電気接触部ＴＩにおいて、上方に打出された基板
部１００両側に一対の弾性挾持腕１３，１３が折曲形成
されている。Further, in the electrical contact portion TI, a pair of elastic clamping arms 13, 13 are bent and formed on both sides of the substrate portion 100 that is punched out upward.

上記構成において、先ず雌端子Ｔを端子収容室１の後方
から挿入すれば、第３図に示すように、弾性挾持腕１３
の前端がストッパ壁６に衝合すると共に、鉄腕１３の後
端に可撓アーム４の係止突・起５が係合して前後方向へ
の抜出しが防止される。In the above configuration, if the female terminal T is first inserted from the rear of the terminal accommodating chamber 1, as shown in FIG.
The front end of the flexible arm 4 abuts against the stopper wall 6, and the locking protrusion/protuberance 5 of the flexible arm 4 engages with the rear end of the iron arm 13 to prevent it from being pulled out in the front-back direction.

一方、端子収容室１の前端における開口手法りは雄端子
Ａに比し充分／Ｊ＼さいので、作業者は雄端子Ａをこの
開口部に臨むように、即ち内部の雌端子Ｔと整合するよ
うに嵌挿すべく注意を喚起される（状態Ｘ）。On the other hand, since the opening at the front end of the terminal storage chamber 1 is sufficiently large compared to the male terminal A, the operator must align the male terminal A with the female terminal T inside so that it faces this opening. Attention is called to insert it in the correct way (state X).

また、開口部が小さいことから、第２図と同様に雄端子
Ａが開口部に対して著しく偏倚している場合には（状態
Ｙ）、その嵌挿ができず、従来のように無理な挿圧によ
る雄端子Ｔの変形等は未然に防止できる。In addition, since the opening is small, if the male terminal A is significantly biased against the opening as shown in Figure 2 (condition Y), it will not be possible to insert it, making it difficult to insert it. Deformation of the male terminal T due to pressurization can be prevented.

更に、雄端子Ａが開口部に面して僅かに傾斜しているよ
・うな場合は（状態２）、可撓性のストッパ壁７が弾性
的に変位して雄端子Ａを嵌挿することができ、同時にス
トッパ壁７０弾性復帰力により矯正力を受け、はぼ整合
する状態になる。Furthermore, if the male terminal A is slightly inclined facing the opening (state 2), the flexible stopper wall 7 will be elastically displaced to allow the male terminal A to be inserted. At the same time, the stopper wall 70 is subjected to a correction force by the elastic restoring force, and is brought into a state of alignment.

第４図は雌端子の他の例を示し、電気接触部Ｔ１におけ
る基板部１０の前端に段付の突片１４を設げたものであ
る。FIG. 4 shows another example of the female terminal, in which a stepped protrusion 14 is provided at the front end of the base plate 10 at the electrical contact portion T1.

なお、この段付の突片１４は、雌端子Ｔを通常帯状の金
属板から連結片を残して連鎖状に形成し、使用時に切断
、分離するものであるが、本考案にあっては前記可撓性

に形成することができる。Note that this stepped protrusion 14 is formed by forming the female terminal T in a chain shape from a band-shaped metal plate, leaving a connecting piece, and is cut and separated during use, but in the present invention, the above-mentioned It can be easily formed by leaving an uncut portion corresponding to the flexible stopper wall I.

このように、雌端子Ｔに段付の突片１４を設げである場
合には、第５図に示す如（、可撓性のストッパ壁１と底
壁３間に形成された溝部９に進入するので、雌端子Ｔは

が防止されることになる。In this way, when the stepped protrusion 14 is provided on the female terminal T, as shown in FIG. Since the female terminal T is inserted into the terminal receiving chamber 1, the female terminal T is positioned within the terminal housing chamber 1 and is prevented from shaking.

以上のように１本考案によれば端子収容室の前方開口端

形のみならずコネクタハウジングの損傷等を未然に防止
することが出来る。As described above, according to the present invention, a flexible stopper wall is provided at the front opening end of the terminal storage chamber, facing the stopper wall protruding and fixed to the upper wall of the storage chamber, and the opening size between both stopper walls is Since the diameter of the male terminal is smaller than that of the male terminal, the male terminal can be inserted in a state that is aligned with the internal female terminal. Not only deformation of the connector housing but also damage to the connector housing can be prevented.

また、雌端子の基板部前端に突片を設げておげば、可撓
性のストッパ壁によって端子収容室における位置決めお
よびガタッキが防止されるので、雄端子の嵌挿等を円滑
に行うことができる。In addition, if a protruding piece is provided at the front end of the female terminal's board, the flexible stopper wall will prevent positioning and wobbling in the terminal accommodation chamber, allowing smooth insertion and insertion of the male terminal. Can be done.
