Abstract

<P>PROBLEM TO BE SOLVED: To prevent an insertion end from being deformed while locking force of a locking arm is kept. <P>SOLUTION: On the locking arm 14 of a rear holder 13 attached to a housing 11, a claw part 14a for locking the rear part of an intermediate part 16b of a connection terminal 16 is formed and a groove part 14b for passing the pin-like insertion end 16a of the connection terminal 16 is formed on the claw part 14a side along the longitudinal direction. When the connection terminal 16 is inserted from the rear side of the housing 11 and the insertion end 16a of the connection terminal 16 passes the locking arm 14, the insertion end 16a passes the groove part 14b and force is never applied to the insertion end 16a from the locking arm 14. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

本発明は、接続端子を内蔵し相手側コネクタハウジングと嵌合するコネクタハウジングに関するものである。   The present invention relates to a connector housing that incorporates a connection terminal and fits into a mating connector housing.

一般に、ハウジング内に収納された接続端子は、特許文献１のように後抜け防止のために、係止アームにより係止されている。   Generally, the connection terminal accommodated in the housing is locked by a locking arm in order to prevent rearward disconnection as in Patent Document 1.

例えば、図６は従来のハウジング１内に接続端子２を収納した電気コネクタハウジングの断面図を示し、接続端子２はハウジング１の後方から挿入されたリアホルダ３に形成された弾発性を有する係止アーム４により係止され、ハウジング１からの後抜けが防止されている。   For example, FIG. 6 shows a cross-sectional view of an electrical connector housing in which a connection terminal 2 is housed in a conventional housing 1, and the connection terminal 2 has a resilience formed on a rear holder 3 inserted from the rear of the housing 1. It is locked by the stop arm 4 to prevent the rearward removal from the housing 1.

特開２００２−１７０６２３号公報JP 2002-170623 A

接続端子２をハウジング１に収納するには、リアホルダ３をハウジングに固定してから、ハウジング１の後方から接続端子２を挿入し、図７に示すように係止アーム４を持ち上げながら、接続端子２を押し込む必要がある。   In order to store the connection terminal 2 in the housing 1, the rear holder 3 is fixed to the housing, the connection terminal 2 is inserted from the rear of the housing 1, and the connection terminal 2 is lifted while lifting the locking arm 4 as shown in FIG. 2 must be pushed in.

しかし、この場合に接続端子２の挿込端２ａが細径の場合などには、挿込端２ａが係止アーム４の弾発力により押し曲げられ、変形を生ずることがある。これは永久変形を与えることもあり、相手側の接続端子と嵌合を行う際の障害となり、場合によっては相手側接続端子と嵌合不能となることがある。   However, in this case, when the insertion end 2 a of the connection terminal 2 has a small diameter, the insertion end 2 a may be pushed and bent by the elastic force of the locking arm 4 and may be deformed. This may cause permanent deformation, which may be an obstacle when mating with the mating connection terminal, and in some cases may not be matable with the mating connection terminal.

また、挿込端２ａに変形を与えないように、係止アーム４の弾発力を小さくすると、接続端子２に対する係止力が弱くなる。   Further, if the elastic force of the locking arm 4 is reduced so as not to deform the insertion end 2a, the locking force for the connection terminal 2 is weakened.

本発明の目的は、上述の課題を解決し、係止アームの係止力を保持したまま、挿込端に変形を与えることのない電気コネクタハウジングを提供することにある。   An object of the present invention is to solve the above-described problems and provide an electrical connector housing that does not deform the insertion end while maintaining the locking force of the locking arm.

上述の目的を達成するための本発明に係る電気コネクタハウジングの技術的特徴は、先端にピン状の挿込端を有する雄型接続端子を内部に収納し、該接続端子を係止アームにより係止するコネクタハウジングにおいて、前記接続端子は中間に前記挿込端よりも幅広の中間部と、後端に電線を圧着する圧着部とを備え、前記係止アームは、前記接続端子の中間部の後部を係止する爪部を有し、該爪部の中央部に前記挿込端を通過させるための溝部を長手方向に形成したことにある。   The technical feature of the electrical connector housing according to the present invention for achieving the above-described object is that a male connection terminal having a pin-like insertion end at the tip is housed inside, and the connection terminal is engaged by a locking arm. In the connector housing to be stopped, the connection terminal includes a middle portion wider than the insertion end in the middle and a crimping portion for crimping the electric wire to the rear end, and the locking arm is provided in the middle portion of the connection terminal. It has a claw part which latches a rear part, and has formed in a longitudinal direction a slot for making the insertion end pass in the central part of the claw part.

本発明に係る電気コネクタハウジングによれば、係止アームの長手方向に溝部を設け、挿込端をこの溝部を通過させることにより、係止アームから挿込端に力が加わることなく接続端子をハウジングに収納できる。   According to the electrical connector housing of the present invention, by providing a groove in the longitudinal direction of the locking arm and passing the insertion end through the groove, the connection terminal can be connected without applying force from the locking arm to the insertion end. Can be stored in a housing.

本発明を図１〜図５に図示の実施例に基づいて詳細に説明する。
図１はハウジングの断面図であり、合成樹脂材から成るハウジング１１は、内部に上下方向に２個、左右方向に複数個の端子収容孔１２が設けられている。ハウジング１１の後部にはリアホルダ１３が固定されており、各端子収容孔１２内にはリアホルダ１３から弾発性を有する係止アーム１４が突設されている。各端子収容孔１２の前方には、接続端子の挿込端が通過する開口１５が設けられている。 The present invention will be described in detail based on the embodiment shown in FIGS.
FIG. 1 is a cross-sectional view of a housing. A housing 11 made of a synthetic resin material is provided with two terminal receiving holes 12 in the vertical direction and a plurality of terminal receiving holes 12 in the horizontal direction. A rear holder 13 is fixed to the rear part of the housing 11, and a locking arm 14 having elasticity is projected from the rear holder 13 in each terminal receiving hole 12. An opening 15 through which the insertion end of the connection terminal passes is provided in front of each terminal accommodating hole 12.

また、係止アーム１４には、接続端子の中間部を係止するための爪部１４ａが設けられ、図２に示すように爪部１４ａ側の長手方向に沿って、接続端子の挿込端を通過させるための溝部１４ｂが形成されている。   In addition, the locking arm 14 is provided with a claw portion 14a for locking the intermediate portion of the connection terminal, and the insertion end of the connection terminal along the longitudinal direction on the claw portion 14a side as shown in FIG. The groove part 14b for letting pass is formed.

図３は接続端子を示し、接続端子１６は導電金属板を打ち抜き、折曲して形成され、前端に断面略四角形のピン状の挿込端１６ａ、中間には挿込端１６ａよりも幅広で略箱型の中間部１６ｂ、後端に電線１７を圧着接続する圧着部１６ｃが設けられている。   FIG. 3 shows a connection terminal. The connection terminal 16 is formed by punching and bending a conductive metal plate. The front end is a pin-shaped insertion end 16a having a substantially square cross section, and the middle is wider than the insertion end 16a. A substantially box-shaped intermediate portion 16b and a crimping portion 16c for crimping and connecting the electric wire 17 to the rear end are provided.

このハウジング１１の端子収容孔１２に、ハウジング１１の後方から接続端子１６を挿入すると、図４に示すように、接続端子１６の挿込端１６ａが係止アーム１４を通過する際には、挿込端１６ａは溝部１４ｂ内を通過し、係止アーム１４から挿込端１６ａに力が加わることがない。   When the connection terminal 16 is inserted into the terminal receiving hole 12 of the housing 11 from the rear of the housing 11, the insertion end 16 a of the connection terminal 16 is inserted when passing through the locking arm 14 as shown in FIG. 4. The insertion end 16a passes through the groove 14b, and no force is applied from the locking arm 14 to the insertion end 16a.

更に、接続端子１６を押し込むと、今度は図５の上段に示すように係止アーム１４は接続端子１６の中間部１６ｂにより押し上げられ、続いて押し込むと挿込端１６ａは開口１５を通過し、図５の下段に示すように、挿込端１６ａは開口１５から前方に突出され正規の位置に収納される。この状態で、係止アーム１４は元の状態に復元して、爪部１４ａが中間部１６ｂの後部を係止し、接続端子１６の後方への抜け止めがなされる。   Further, when the connecting terminal 16 is pushed in, the locking arm 14 is pushed up by the intermediate portion 16b of the connecting terminal 16 as shown in the upper part of FIG. 5, and when the pushing is continued, the insertion end 16a passes through the opening 15, As shown in the lower part of FIG. 5, the insertion end 16 a protrudes forward from the opening 15 and is stored in a proper position. In this state, the locking arm 14 is restored to the original state, the claw portion 14a locks the rear portion of the intermediate portion 16b, and the connection terminal 16 is prevented from coming off backward.

このように、接続端子１６の挿入に際して、挿込端１６ａは係止アーム１４から力を受けることがないので、変形することもない。また、接続端子１６の挿入前に挿込端１６ａが例えば水平方向、或いは上方に変形している場合には、係止アーム１４の溝部１４ｂによりその曲りが矯正されることもある。   In this manner, when the connection terminal 16 is inserted, the insertion end 16a does not receive a force from the locking arm 14 and therefore does not deform. Further, when the insertion end 16 a is deformed, for example, in the horizontal direction or upward before the connection terminal 16 is inserted, the bending may be corrected by the groove portion 14 b of the locking arm 14.

なお、実施例では係止アーム１４はリアホルダ１３に設けたが、リアホルダを使用しない場合には、ハウジング１１に係止アーム１４を直接設けることもできる。   In the embodiment, the locking arm 14 is provided on the rear holder 13. However, when the rear holder is not used, the locking arm 14 may be provided directly on the housing 11.
