Description

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

特許文献１には、コネクタハウジング内にキャビティが形成され、コネクタハウジングの後方から端子金具をキャビティ内に挿入する技術が開示されている。キャビティには、端子金具の挿入方向と交差する方向へ弾性変位可能なランスが形成され、端子金具をキャビティに挿入する過程では、ランスが端子金具と干渉して弾性撓みする。端子金具が正規位置まで挿入されると、ランスが弾性復帰して端子金具に係止することにより、端子金具が抜止め状態に保持される。 Patent Document 1 discloses a technique in which a cavity is formed in a connector housing and a terminal fitting is inserted into the cavity from the rear of the connector housing. A lance is formed in the cavity so as to be elastically displaceable in a direction intersecting the insertion direction of the terminal fitting, and in the process of inserting the terminal fitting into the cavity, the lance interferes with the terminal fitting and elastically bends. When the terminal fitting is inserted to the proper position, the lance elastically returns to engage with the terminal fitting, so that the terminal fitting is held in the pulled-out state.

特開２０１４−８２０１５号公報JP, 2014-82015, A

端子金具をコネクタハウジングに取り付ける際には、端子金具の後端部に固着した電線を摘んで端子金具をキャビティ内に押し込む。端子金具の挿入過程では、ランスが弾性撓みすると、ランスの弾性復元力に起因する挿入抵抗が端子金具に作用する。そのため、ランスの挿入抵抗によって電線が座屈し、端子金具の挿入作業に支障を来すことが懸念される。 When attaching the terminal fitting to the connector housing, pinch the wire fixed to the rear end of the terminal fitting and push the terminal fitting into the cavity. When the lance elastically bends in the process of inserting the terminal fitting, the insertion resistance resulting from the elastic restoring force of the lance acts on the terminal fitting. Therefore, there is a concern that the wire may buckle due to the insertion resistance of the lance, which may hinder the insertion work of the terminal fitting.

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、電線の座屈を防止することを目的とする。 The present invention was completed in view of the above circumstances, and an object thereof is to prevent buckling of electric wires.

収容室を貫通する電線に端子金具が固着された状態で、電線を後方へ引っ張ると、端子金具の少なくとも一部が収容室に収容され、保持部材がストッパに当たる。これにより、端子金具がハウジングに取り付けられる。端子金具をハウジングに取り付ける際には、電線を引っ張ればよいので、電線の座屈を防止することができる。 When the wire is pulled rearward while the terminal fitting is fixed to the wire penetrating the housing, at least a part of the terminal fitting is housed in the housing and the holding member hits the stopper. Thereby, the terminal fitting is attached to the housing. When the terminal fitting is attached to the housing, the electric wire only has to be pulled, so that the electric wire can be prevented from buckling.

The front surface of the first retaining portion 25A is a first locking surface 26A that is perpendicular to the front-rear direction (direction parallel to the mounting direction of the first terminal module 21A to the housing 10). The rear surface of the first retaining portion 25A is a first guide surface 27A that is inclined with respect to the front-back direction.

第１端子金具２８Ａは、細長い金属材料に曲げ加工を施したものである。第１端子金具２８Ａの側面視形状は段差状に屈曲した形状である。第１端子金具２８Ａは、第１保持部材２２Ａに対し後方から第１取付孔２３Ａに圧入することによって組み付けられて一体化されている。第１取付孔２３Ａには、第１端子金具２８Ａの第１被保持部２９Ａが収容されている。 The first terminal fitting 28A is formed by bending an elongated metal material.

次に、本実施例のコネクタの製造工程及び組付け工程を説明する。図４〜６に示すように、各保持部材２２Ａ，２２Ｂに対し複数の端子金具２８Ａ，２８Ｂを後方から組み付けて、端子モジュール２１Ａ，２１Ｂを構成する。また、端子モジュール２１Ａ，２１Ｂの製造工程と前後して、ハウジング１０の各貫通孔１４Ａ，１４Ｂに、夫々、電線３２Ａ，３２Ｂを挿通しておく。 Next, a manufacturing process and an assembling process of the connector of this embodiment will be described. As shown in FIGS. 4 to 6, a plurality of terminal fittings 28A and 28B are assembled to the holding members 22A and 22B from the rear to form terminal modules 21A and 21B. Before and after the manufacturing process of the terminal modules 21A and 21B, the electric wires 32A and 32B are inserted into the through holes 14A and 14B of the housing 10, respectively.

次に、ハウジング１０の前方において、各端子金具２８Ａ，２８Ｂの固着部３１Ａ，３１Ｂに電線３２Ａ，３２Ｂの前端部を接続する。これにより、図７に示すように、導電路２０Ａ，２０Ｂが、電線３２Ａ，３２Ｂをハウジング１０に貫通させた状態で製造される。この後、ハウジング１０の後方へ導出されている電線３２Ａ，３２Ｂを後方へ引っ張ると、導電路２０Ａ，２０Ｂがハウジング１０に対して後方へ相対移動し、導電路２０Ａ，２０Ｂがハウジング１０に組み付けられる。 Next, in front of the housing 10, the front ends of the electric wires 32A and 32B are connected to the fixing portions 31A and 31B of the terminal fittings 28A and 28B. As a result, as shown in FIG. 7, the conductive paths 20A and 20B are manufactured with the electric wires 32A and 32B penetrating the housing 10. After that, when the electric wires 32A, 32B led out to the rear of the housing 10 are pulled rearward, the conductive paths 20A, 20B relatively move rearward with respect to the housing 10, and the conductive paths 20A, 20B are assembled to the housing 10. .

導電路２０Ａ，２０Ｂがハウジング１０に組み付けられる過程では、保持部材２２Ａ，２２Ｂの誘導面２７Ａ，２７Ｂが抜止め突起１９Ａ，１９Ｂに摺接し、抜止め突起１９Ａ，１９Ｂが弾性変形することによって抜止め部２５Ａ，２５Ｂが抜止め突起１９Ａ，１９Ｂを通過する。この間、端子金具２８Ａ，２８Ｂの固着部３１Ａ，３１Ｂが貫通孔１４Ａ，１４Ｂ内に収容されるとともに、保持部材２２Ａ，２２Ｂの後端側部分が凹部１５Ａ，１５Ｂ内に嵌入される。 In the process of assembling the conductive paths 20A, 20B to the housing 10, the guide surfaces 27A, 27B of the holding members 22A, 22B are brought into sliding contact with the retaining projections 19A, 19B, and the retaining projections 19A, 19B are elastically deformed to prevent retaining. The parts 25A and 25B pass through the retaining projections 19A and 19B. During this time, the fixed portions 31A, 31B of the terminal fittings 28A, 28B are housed in the through holes 14A, 14B, and the rear end side portions of the holding members 22A, 22B are fitted in the recesses 15A, 15B.

導電路２０Ａ，２０Ｂが正規の組付け状態に至ると、保持部材２２Ａ，２２Ｂの後面がストッパ１６Ａ，１６Ｂに当接することにより、ハウジング１０に対する保持部材２２Ａ，２２Ｂ（導電路２０Ａ，２０Ｂ）の後方への相対移動が規制される。これと同時に、保持部材２２Ａ，２２Ｂの係止面２６Ａ，２６Ｂが抜止め突起１９Ａ，１９Ｂに対して後方から係止することにより、ハウジング１０に対する保持部材２２Ａ，２２Ｂ（導電路２０Ａ，２０Ｂ）の前方への相対移動（ハウジング１０からの離脱）が規制される。以上により、コネクタの製造と組付けが完了する。 When the conductive paths 20A and 20B reach the proper assembled state, the rear surfaces of the holding members 22A and 22B come into contact with the stoppers 16A and 16B, so that the holding members 22A and 22B (conductive paths 20A and 20B) are rearward relative to the housing 10. The movement relative to is restricted. At the same time, the engaging surfaces 26A, 26B of the holding members 22A, 22B engage with the retaining projections 19A, 19B from the rear, so that the holding members 22A, 22B (conductive paths 20A, 20B) with respect to the housing 10 are secured. Relative movement to the front (separation from the housing 10) is restricted. The above completes the manufacture and assembly of the connector.
