【０００３】[0003]
このような従来の端子抜け防止コネクタでは、第２の端子係止突起ホルダー４ には各第２の端子係止突起６が単に固設されていただけなので、各第２の端子係 止突起６が端子の抜けを検知しても、第２の端子係止突起ホルダー４が図７に示 すようにアーチ型に変形しながらロック具５ａ，５ｂで該コネクタハウジング１ にロックされしまう問題点があった。このため図８に示すように、該端子抜け防 止コネクタは第２の端子係止突起ホルダー４が変形しつつ導通チエッカー７にも セットされてしまい、端子抜けが結果的に検知されないことがあり、端子抜け検 知の信頼性が低い問題点があった。 In such a conventional terminal detachment prevention connector, since each second terminal locking projection 6 is simply fixed to the second terminal locking projection holder 4, each second terminal locking projection 6 is not fixed. Even if the disconnection of the terminal is detected, there is a problem that the second terminal locking projection holder 4 is deformed into an arch shape as shown in FIG. 7 and is locked to the connector housing 1 by the locks 5a and 5b. It was Therefore, as shown in FIG. 8, the terminal disconnection prevention connector may be set in the conduction checker 7 while the second terminal locking projection holder 4 is deformed, and the terminal disconnection may not be detected as a result. However, there was a problem that the reliability of the pin disconnection detection was low.

【実施例】 図１〜図５は、本考案に係る端子抜け防止コネクタの一実施例を示したもので ある。本実施例の端子抜け防止コネクタは、コネクタハウジング１内に複数の端 子収容室２が並設され、各端子収容室２には収容する端子８を第１の端子係止突 起９で係止する第１の端子係止アーム１０が片持ち支持でそれぞれ設けられてい る。第１の端子係止突起９は、端子８の図示しない係止窓に挿入されて係止が行 われるようになっている。また、コネクタハウジング１にはヒンジ部３で第２の 端子係止突起ホルダー４の基端側が回動自在に支持されている。該第２の端子係 止突起ホルダー４の自由端側はロック具５ａ，５ｂでコネクタハウジング１にロ ックされるようになっている。Embodiment FIG. 1 to FIG. 5 show an embodiment of a terminal disconnection prevention connector according to the present invention. In the terminal slip-out preventing connector of this embodiment, a plurality of terminal accommodating chambers 2 are arranged side by side in a connector housing 1, and terminals 8 to be accommodated in each terminal accommodating chamber 2 are engaged by a first terminal locking protrusion 9. A first terminal locking arm 10 for stopping is provided by cantilever support. The first terminal locking projection 9 is inserted into a locking window (not shown) of the terminal 8 so as to be locked. A hinge portion 3 of the connector housing 1 rotatably supports a base end side of a second terminal locking projection holder 4. The free end side of the second terminal locking projection holder 4 is adapted to be locked to the connector housing 1 by locks 5a and 5b.
【０００８】 該第２の端子係止突起ホルダー４には，各端子収容室２に対応して第２の端子 係止アーム１１がスリット１２による区画で片持ち支持構造にそれぞれ設けられ ている。これら各第２の端子係止アーム１１の自由端には、第２の端子係止突起 ６がそれぞれ設けられている コネクタハウジング１には、各第２の端子係止突起６を各端子収容室２内に挿 入する窓１３が設けられている。各端子収容室２内に挿入された第２の端子係止 突起６は、端子８の筒状接触部８ａの後部に係止され、端子抜けが防止されるよ うになっている。The second terminal locking projection holder 4 is provided with a second terminal locking arm 11 corresponding to each terminal accommodating chamber 2 in a cantilevered support structure in a partition defined by slits 12. The second terminal locking protrusions 6 are provided at the free ends of the respective second terminal locking arms 11, and the connector housing 1 is provided with the second terminal locking protrusions 6. A window 13 is provided to be inserted into the inside 2. The second terminal locking projection 6 inserted into each terminal accommodating chamber 2 is locked to the rear portion of the cylindrical contact portion 8a of the terminal 8 to prevent the terminal from coming off.
【０００９】 なお、１４は端子８の後部に接続されているリード線である。Reference numeral 14 is a lead wire connected to the rear portion of the terminal 8.
【００１０】 このような端子抜け防止コネクタは、図３に示すように第２の端子係止突起ホ ルダー４をコネクタハウジング１から立ち上げた状態で、該コネクタハウジング １の後部から各端子８を各端子収容室２内に挿入する。Such a terminal slip-out preventing connector has a structure in which the second terminal locking projection holder 4 is raised from the connector housing 1 as shown in FIG. It is inserted into each terminal accommodating chamber 2.
【００１１】 このとき図４に示すように端子８の挿入が不十分な状態で、第２の端子係止突 起ホルダー４を倒して該第２の端子係止突起ホルダー４をロック具５ａ，５ｂで コネクタハウジング１にロックした場合には、第２の端子係止突起６が端子８に 当たり、端子収容室２内に挿入できず、このためスリット１２で自由端側がフリ ーになっている第２の端子係止アーム１１の該自由端側が該図４に示すように該 第２の端子係止突起ホルダー４の表面に突出する。At this time, as shown in FIG. 4, in a state where the terminal 8 is not sufficiently inserted, the second terminal locking projection holder 4 is tilted down to lock the second terminal locking projection holder 4 into the locking tool 5a, When the connector housing 1 is locked by 5b, the second terminal locking projection 6 hits the terminal 8 and cannot be inserted into the terminal accommodating chamber 2, so that the slit 12 is free on the free end side. The free end side of the second terminal locking arm 11 projects to the surface of the second terminal locking projection holder 4 as shown in FIG.
【００１２】 このため該第２の端子係止アーム１１の自由端側が第２の端子係止突起ホルダ ー４の外に突出していることを知ることにより、端子抜けが検知できる。Therefore, by knowing that the free end side of the second terminal locking arm 11 is projected to the outside of the second terminal locking projection holder 4, it is possible to detect the terminal omission.
【００１３】 また、図５に示すように端子８が端子収容室２内に十分に挿入され、該端子８ が第１の端子係止アーム１０の自由端の第１の端子係止突起９で係止された状態 で、第２の端子係止突起ホルダー４を倒して該第２の端子係止突起ホルダー４を ロック具５ａ，５ｂでコネクタハウジング１にロックした場合には、第２の端子 係止突起６が端子８の筒状接触部８ａの後部に係止され、端子抜けが２重に防止 される。この状態では、第２の端子係止アーム１１の自由端側は、第２の端子係 止突起ホルダー４の表面には突出しない。Further, as shown in FIG. 5, the terminal 8 is fully inserted into the terminal accommodating chamber 2, and the terminal 8 is formed by the first terminal locking protrusion 9 at the free end of the first terminal locking arm 10. In the locked state, the second terminal locking projection holder 4 is tilted down to lock the second terminal locking projection holder 4 on the connector housing 1 with the locks 5a and 5b. The locking projection 6 is locked to the rear portion of the cylindrical contact portion 8a of the terminal 8 to prevent the terminal from falling off twice. In this state, the free end side of the second terminal locking arm 11 does not project to the surface of the second terminal locking projection holder 4.
