Description

本発明は、ハウジング本体の端子収容孔、リアホルダの端子挿通孔の配置を工夫して、小型で使い易い電気コネクタハウジングに関するものである。 The present invention relates to an electric connector housing that is small and easy to use by devising the arrangement of terminal receiving holes of a housing body and terminal insertion holes of a rear holder.

図６に示すように、接続端子１の接続部２にスタビライザ部３を設けて、ハウジングに収納した後の接続端子１のハウジング内での揺動防止と、ハウジングに挿入する際の逆挿し防止を持たせている場合がある。 As shown in FIG. 6, the stabilizer 3 is provided in the connection part 2 of the connection terminal 1 to prevent the connection terminal 1 from swinging in the housing after being housed in the housing, and to prevent reverse insertion when inserted into the housing. May be held.

この場合のハウジングにおける接続端子１に対する端子収容孔４の断面は、図７に示すように四角状の断面であり、内部の上部に壁部５が設けられ、スタビライザ部３を収納するためのスタビライザ収納部６が付設されている。 The cross section of the terminal receiving hole 4 with respect to the connection terminal 1 in the housing in this case is a square cross section as shown in FIG. 7, and a wall portion 5 is provided in the upper part inside, and a stabilizer for housing the stabilizer portion 3. A storage unit 6 is attached.

ハウジング内に収納した接続端子を個々に固定するために、ハウジングにリアホルダを付設する場合がある。通常のリアホルダの端子挿通孔は、複数の接続端子を一括して挿入するように大きい開口となっているか、或いは接続端子ごとに端子挿通孔を設けているとしても、スタビライザ部の形状まで考慮されてはいない。 In order to individually fix the connection terminals housed in the housing, a rear holder may be attached to the housing. The terminal insertion hole of a normal rear holder has a large opening so that a plurality of connection terminals can be inserted all at once, or even if a terminal insertion hole is provided for each connection terminal, the shape of the stabilizer portion is considered. Not.

しかし、ハウジング本体にリアホルダを係止した状態で、接続端子をリアホルダを経由してハウジング本体の端子収容孔に挿通するには、リアホルダが邪魔になって奥部のハウジング本体の端子収容孔の位置、スタビライザ部の向きが十分に確認できないために、接続端子の挿入に難渋する。 However, in order to insert the connection terminal into the terminal receiving hole of the housing main body via the rear holder while the rear holder is locked to the housing main body, the position of the terminal receiving hole of the housing main body at the back is obstructed by the rear holder. Since the orientation of the stabilizer portion cannot be sufficiently confirmed, it is difficult to insert the connection terminal.

特許文献１には、ハウジングにおけるこのような上下の端子収容孔のスタビライザ収納部を向き合わせることにより効率的に配置して、ハウジングの高さを低くすることが開示されている。 Patent Document 1 discloses that the height of the housing is lowered by efficiently arranging the stabilizer accommodating portions of the upper and lower terminal accommodating holes in the housing.

本発明の目的は、上述の課題を解消し、ハウジング本体に付設したリアホルダの端子挿通孔パターンをハウジング本体のスタビライザ収納部を含む端子収容孔パターンと同形状とし、接続端子挿入の容易性をもたらし、ハウジング高を低くできる電気コネクタハウジングを提供することにある。 The object of the present invention is to solve the above-mentioned problems, and to make the terminal insertion hole pattern of the rear holder attached to the housing body the same shape as the terminal accommodation hole pattern including the stabilizer housing portion of the housing body, thereby facilitating the insertion of the connection terminal. An object of the present invention is to provide an electrical connector housing that can reduce the height of the housing.

上記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、接続部の上方又は下方の片側にスタビライザ部を突設した複数の受け用接続端子を収容する複数段の端子収容孔をハウジング本体に形成し、該ハウジング本体の後部に別体のリアホルダを付設可能とし、前記端子収容孔は上下対称に前記端子収容孔のスタビライザ収納部が向かい合うように配置して、前記上下の端子収容孔間の隔壁に段差を設け、前記リアホルダの端子挿通孔は前記ハウジング本体に設けた前記端子収容孔の断面と同形状に形成して同じに配列し、前記リアホルダを前記ハウジング本体に連結した状態において、前記リアホルダの端子挿通孔と前記ハウジング本体の端子収容孔は個々に同形状に連通するようにしたことにある。 In order to achieve the above object, the technical feature of the electrical connector housing according to the present invention is that a plurality of stages of terminal receiving holes for receiving a plurality of receiving connection terminals having a stabilizer portion projecting from one side above or below the connecting portion. Is formed in the housing body, and a separate rear holder can be attached to the rear part of the housing body. The terminal housing holes are symmetrically arranged so that the stabilizer housing portions of the terminal housing holes face each other, and the upper and lower terminals are arranged. Steps are provided in the partition walls between the receiving holes, and the terminal insertion holes of the rear holder are formed in the same shape as the cross-section of the terminal receiving holes provided in the housing body, and the rear holder is connected to the housing body. In this state, the terminal insertion hole of the rear holder and the terminal receiving hole of the housing body are individually communicated with each other in the same shape.

本発明に係る電気コネクタハウジングによれば、ハウジングの高さを低くできると共に、リアホルダを付加したハウジングであっても、スタビライザ部を有する接続端子をハウジング内に容易に挿入することができる。 According to the electrical connector housing of the present invention, the height of the housing can be reduced, and even if the housing is provided with a rear holder, the connection terminal having the stabilizer portion can be easily inserted into the housing.

本発明を図１〜図５に図示の実施の形態に基づいて詳細に説明する。
図１はハウジング本体及びリアホルダの斜視図であり、接続端子をハウジング本体１１の端子収容孔１２内に挿入する際には、予め図２に示すようにハウジング本体１１の後部に別体のリアホルダ２１を連結させておく。この連結は図示を省略しているが、爪部、凹部などの連結機構により、リアホルダ２１をハウジング１１の後部に押し込むことによりなされる。 The present invention will be described in detail based on the embodiment shown in FIGS.
FIG. 1 is a perspective view of a housing body and a rear holder. When inserting a connection terminal into the terminal receiving hole 12 of the housing body 11, a separate rear holder 21 is provided at the rear of the housing body 11 as shown in FIG. Are connected. Although not shown, this connection is made by pushing the rear holder 21 into the rear part of the housing 11 by a connection mechanism such as a claw or a recess.

リアホルダ２１には、接続端子を通過させるための端子挿通孔２２が形成されており、この端子挿通孔２２はハウジング本体１１の端子収容孔１２の形状と一致し、かつ配列も一致している。従って、リアホルダ２１をハウジング本体に連結した状態で、端子挿通孔２２と端子収容孔１２は同形状に連通するようになっている。 The rear holder 21 is formed with a terminal insertion hole 22 for allowing the connection terminal to pass through. The terminal insertion hole 22 matches the shape of the terminal receiving hole 12 of the housing body 11 and the arrangement also matches. Therefore, the terminal insertion hole 22 and the terminal receiving hole 12 communicate with each other in the same shape with the rear holder 21 connected to the housing body.

端子収容孔１２は図３に示すように、ハウジング本体１１の背面に多数の入口部が２段に開口されている。これらの各端子収容孔１２の入口部は図４に拡大して示すように、四角状の収容孔本体１３の上部又は下部の片寄った位置にスタビライザ収納部１４が設けられている。上下の端子収容孔１２においては、スタビライザ収納部１４同士が向き合うように、つまり上方の端子収容孔１２のスタビライザ収納部１４がない部分と、下方の端子収容孔１２のスタビライザ収納部１４とが相互に向き合うようにして隔壁１５が設けられ、この隔壁１５には段差が形成されている。 As shown in FIG. 3, the terminal accommodating hole 12 has a large number of inlet portions opened in two stages on the back surface of the housing body 11. As shown in the enlarged view of FIG. 4, the inlet portion of each terminal accommodating hole 12 is provided with a stabilizer accommodating portion 14 at an offset position on the upper or lower portion of the rectangular accommodating hole main body 13. In the upper and lower terminal accommodating holes 12, the stabilizer accommodating portions 14 face each other, that is, the portion without the stabilizer accommodating portion 14 of the upper terminal accommodating hole 12 and the stabilizer accommodating portion 14 of the lower terminal accommodating hole 12 are mutually connected. A partition wall 15 is provided so as to face each other, and a step is formed in the partition wall 15.

ここで、端子収容孔１２の高さをｈ、隔壁１５の厚みをｄとし、スタビライザ収納部１４の高さをｈ’とすると、上下２個の端子収容孔１２を合わせた大きさＴは、Ｔ＝２ｈ＋ｄ−ｈ’となり、図７に示した端子収容孔４を単に並べただけの例えば図５と比較して、一方のスタビライザ収納部１４の高さｈ’分だけ端子収容孔１２を合わせた大きさを小さくすることができる。 Here, when the height of the terminal accommodating hole 12 is h, the thickness of the partition 15 is d, and the height of the stabilizer accommodating portion 14 is h ′, the size T of the two upper and lower terminal accommodating holes 12 is given by T = 2h + d−h ′, and the terminal accommodating hole 12 is aligned by the height h ′ of one stabilizer accommodating portion 14 as compared with, for example, FIG. 5 in which the terminal accommodating holes 4 shown in FIG. 7 are simply arranged. The size can be reduced.

この図３に示す端子収容孔１２のパターンは、上述したようにリアホルダ２１の端子挿通孔２２にスタビライザ挿通孔を設けた同一形状とされており、リアホルダ２１をハウジング本体１１の後方に連結すれば、接続端子１はリアホルダ２１の端子挿通孔２２にスタビライザ部３の位置を合わせて挿入すると、ハウジング本体１１の端子収容孔１２にそのまま押し込むことができる。 The pattern of the terminal receiving hole 12 shown in FIG. 3 is the same shape in which the stabilizer insertion hole is provided in the terminal insertion hole 22 of the rear holder 21 as described above, and if the rear holder 21 is connected to the rear of the housing body 11. When the connection terminal 1 is inserted into the terminal insertion hole 22 of the rear holder 21 with the position of the stabilizer 3 aligned, the connection terminal 1 can be pushed into the terminal accommodation hole 12 of the housing body 11 as it is.

なお、図６においては、接続端子１のスタビライザ部３は接続部２の上部に形成されたものについて説明したが、スタビライザ部３を接続部２の下部に設けた場合でも同様である。 In FIG. 6, the stabilizer portion 3 of the connection terminal 1 has been described as being formed on the upper portion of the connection portion 2, but the same applies to the case where the stabilizer portion 3 is provided on the lower portion of the connection portion 2.

また、ハウジング本体１１内の接続端子１の端子収納孔１２は、実施例のように２段にするとは限らず、３段以上に配置する場合においても同様に適用できる。なお、これらの場合に特に偶数段に配置する場合が、スラビライザ収納部１４の一方の高さｈ’を相殺できるので効果が大きい。 Further, the terminal receiving holes 12 of the connection terminals 1 in the housing body 11 are not limited to two stages as in the embodiment, and can be similarly applied to the case where they are arranged in three or more stages. Note that, in these cases, the arrangement in the even-numbered stages is particularly effective because one height h ′ of the stabilizer housing portion 14 can be offset.
