特開平9−213436号公報JP-A-9-213436

しかし、上記のものでは連結部の切り離しがコネクタのハウジング内においてなされるため、万一、除去された連結部がハウジング内に放置されてしまうと短絡の虞が生じる、という問題点があった。   However, in the above, since the connecting portion is disconnected in the housing of the connector, there is a problem that a short circuit may occur if the removed connecting portion is left in the housing.

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、連鎖状端子から切り離された連結部によって端子間が短絡してしまう事態を有効に回避することができるコネクタを提供することを目的とする。   The present invention has been completed based on the above situation, and provides a connector capable of effectively avoiding a situation in which terminals are short-circuited by a connecting portion cut off from a chained terminal. With the goal.

本発明のコネクタは、合成樹脂製のコネクタハウジングと、複数の端子が連結部を介して連鎖状に連なりかつ全体がコネクタハウジング内に組み込まれた状態で連結部が選択的に切り離される連鎖状端子とを備え、コネクタハウジングには切断された連結部を保持する保持部が形成されていることを特徴とする。   The connector of the present invention includes a connector housing made of synthetic resin, and a chained terminal in which a plurality of terminals are linked in a chained manner via a coupling portion, and the coupling portion is selectively disconnected in a state where the whole is incorporated in the connector housing The connector housing is formed with a holding portion for holding the cut connecting portion.

本発明によれば、複数の端子から連結部を選択的に切り離すことで、種々の短絡パターンを設定することができる。その場合において、切り離された連結部はコネクタハウジングの保持部によって保持されてずれることがないため、切り離された連結部によって端子同士が不用意に短絡してしまう事態を回避することができる。   According to the present invention, various short-circuit patterns can be set by selectively disconnecting the connecting portion from the plurality of terminals. In that case, since the separated connecting portion is not held and displaced by the holding portion of the connector housing, it is possible to avoid a situation where the terminals are inadvertently short-circuited by the separated connecting portion.

まず、本発明における好ましい実施の形態を説明する。
端子に相手端子と接続するタブ部が形成される一方、コネクタハウジングにはタブ部が圧入状態で貫通する端子支持壁が形成され、この端子支持壁のうち連結部と対向する部位が前記保持部とされ、端子支持壁には切り離された連結部とこの連結部によって連結されていた端子との間に介在される短絡防止壁が形成されている構成である。
このように、連結部と端子との間に短絡防止壁が介在されれば、万一、保持部による連結部の保持が緩んで変位するような事態が生じたとしても、連結部が誤って端子同士を短絡させてしまう事態を回避することができる。
First, a preferred embodiment in the present invention will be described.
While the terminal is formed with a tab portion that connects to the mating terminal, the connector housing is formed with a terminal support wall through which the tab portion penetrates in a press-fit state, and the portion of the terminal support wall that faces the connecting portion is the holding portion. The terminal support wall has a configuration in which a short-circuit prevention wall interposed between the disconnected connecting portion and the terminal connected by the connecting portion is formed.
In this way, if a short-circuit prevention wall is interposed between the connecting portion and the terminal, even if a situation occurs in which the holding portion is held loose by the holding portion and displaced, the connecting portion is erroneously A situation where the terminals are short-circuited can be avoided.

連結部には保持部に突き刺さって保持される突入部が突出して形成されるとともに、この突入部は先端側に尖るくさび状に形成されている構成としてもよい。   The connecting portion may be formed with a protruding portion that is pierced and held by the holding portion, and the protruding portion may be formed in a wedge shape that is pointed toward the distal end side.

このような構成によれば、連結部の突入部が保持部に突き刺さると、突入部の先端のくさび作用により、端子支持壁の肉がタブ部側へ寄せられるため、タブ部に対する保持力が高められる。   According to such a configuration, when the protruding portion of the connecting portion pierces the holding portion, the wedge support action at the tip of the protruding portion causes the meat of the terminal support wall to be moved toward the tab portion side, thereby increasing the holding force for the tab portion. It is done.

連結部の側縁部は短絡防止壁に圧入可能な構成としてもよい。
この構成によれば、連結部は保持部によって保持されることに加え、短絡防止壁にも圧着される。したがって、連結部自体の保持力が一層高められる。
It is good also as a structure which can press-fit the side edge part of a connection part in a short circuit prevention wall.
According to this structure, in addition to being held by the holding portion, the connecting portion is also crimped to the short-circuit prevention wall. Therefore, the holding power of the connecting portion itself is further enhanced.

<実施例>
次に、本発明のコネクタを具体化した実施例について図面を参照しつつ説明する。
本実施例のコネクタ(ジョイントコネクタ)は合成樹脂製のコネクタハウジング1を有している。コネクタハウジング1は図2に示すように、互いに反対方向へ開口する第1・第2のフード部2,3を有し、両フード部2,3は端子支持壁4によって区画されている。この端子支持壁4には複数の端子5が圧入によって支持されている。図1に示すように、端子5は両フード部2.3内において幅方向に6本、高さ方向に二段が配置されている。
<Example>
Next, an embodiment embodying the connector of the present invention will be described with reference to the drawings.
The connector (joint connector) of this embodiment has a connector housing 1 made of synthetic resin. As shown in FIG. 2, the connector housing 1 has first and second hood portions 2 and 3 that open in opposite directions, and both the hood portions 2 and 3 are partitioned by a terminal support wall 4. A plurality of terminals 5 are supported on the terminal support wall 4 by press-fitting. As shown in FIG. 1, six terminals 5 are arranged in the width direction and two stages in the height direction in both hood parts 2.3.

本実施例における各端子5は、コネクタハウジング1への組み込みの際には2本を一組とした連鎖状端子Tとなっている。すなわち、1対の端子5を切り離し可能な連結部10によって連結した構成となっている。なお、連鎖状端子Tにおける連鎖の数は限定されるべきものではない。   Each terminal 5 in the present embodiment is a chained terminal T that is a set of two when assembled into the connector housing 1. In other words, the pair of terminals 5 are connected by the detachable connecting portion 10. The number of chains in the chain terminal T should not be limited.

各端子5は金属製の平板材によって形成され、長手方向両側には第1・第2のタブ部6,7が形成され、それぞれ相手端子と接続可能である。第1タブ部6側は第2タブ部7よりも長く形成され、両タブ部6,7間には長手方向と直交する方向へ幅広部8が張出している。第1タブ部6において幅広部8寄りには抜け止め爪9が形成されている。   Each terminal 5 is formed of a metal flat plate material. First and second tab portions 6 and 7 are formed on both sides in the longitudinal direction, and can be connected to a mating terminal. The first tab portion 6 side is formed longer than the second tab portion 7, and the wide portion 8 projects between the tab portions 6 and 7 in a direction perpendicular to the longitudinal direction. A retaining tab 9 is formed near the wide portion 8 in the first tab portion 6.

連結部10は、連鎖状端子Tにおける両幅広部8の対向縁の奥側端部に薄肉部11を介して連結されている。連結部10の後縁(図2における下側の縁)は図示しない切断用治具によって押込みを行うための押込み縁12となっている。また、連結部10の幅方向両側縁は後端側に行くにつれ徐々に幅広となるようなくさび状に形成されて圧入縁13となっている。連結部10において、圧入縁13より先端側には段差を介して突入部14が突出形成されている。突入部14は先端が尖った矢じり状をなすとともに、圧入縁13と同様、後端へ行くにつれて幅広となるくさび形状に形成されている。   The connecting part 10 is connected to the back end part of the opposite edge of the both wide parts 8 in the chain terminal T via the thin part 11. The rear edge (lower edge in FIG. 2) of the connecting portion 10 is a pushing edge 12 for pushing with a cutting jig (not shown). Further, both side edges in the width direction of the connecting portion 10 are formed in a wedge shape so as to gradually increase in width toward the rear end side, thereby forming press-fit edges 13. In the connecting portion 10, a protruding portion 14 is formed protruding from the press-fit edge 13 through a step. The intrusion portion 14 has an arrowhead shape with a sharp tip, and is formed in a wedge shape that becomes wider as it goes to the rear end, like the press-in edge 13.

端子支持壁4において第2フード部3側の奥壁には、各連鎖状端子Tを取付けるための装着凹部15が凹み形成されている。各装着凹部15は図1に示すように、幅方向へ横長となるように形成され、図2に示すように、奥部へ行くにつれて段階的に幅狭となるように形成されている。装着凹部15における手前側部分の幅方向両端部にはストッパ面16が段差状に形成されている。両ストッパ面16は連鎖状端子Tを各装着凹部15へ圧入したときに、各端子5の幅広部8の先端縁が当接することで、連鎖状端子Tを正規組み付け位置において前止まりさせる。   In the terminal support wall 4, a mounting recess 15 for attaching each chained terminal T is formed in the back wall on the second hood portion 3 side. As shown in FIG. 1, each mounting recess 15 is formed so as to be horizontally long in the width direction, and as shown in FIG. Stopper surfaces 16 are formed in steps at both ends in the width direction of the front side portion of the mounting recess 15. When the chained terminals T are press-fitted into the respective mounting recesses 15, the both stopper surfaces 16 abut the leading edges of the wide portions 8 of the terminals 5 to stop the chained terminals T at the regular assembly position.

各装着凹部15においてストッパ面16より奥部でその幅方向内側に隣接した部位には第1フード部2内へ貫通する端子差し込み孔17が一対設けられている。両端子差し込み孔17の内部は第1タブ部6が圧入される程度の大きさである。   A pair of terminal insertion holes 17 penetrating into the first hood portion 2 is provided in a portion of each mounting recess 15 adjacent to the inner side in the width direction behind the stopper surface 16. The insides of both terminal insertion holes 17 are large enough to allow the first tab portion 6 to be press-fitted.

各装着凹部15の最も奥部で両端子差し込み孔17に挟まれた部位で、連結部10と対向する部位は連結部10を保持するための保持部18が凹み形成されている。この保持部18は、連鎖状端子Tが端子支持壁4に支持された状態で、連結部10の突入部14がほぼ付け根位置まで突っ込まれるようにしてある。また、図3に示すように、連鎖状端子Tから連結部10が切り離されたときには、突入部14の先端が保持部18の奥壁に突き刺さることで連結部10全体がコネクタハウジング1内に保持される。   A holding part 18 for holding the connecting part 10 is formed in a recessed part at a part that is sandwiched between both terminal insertion holes 17 at the innermost part of each mounting recess 15. The holding portion 18 is configured such that the protruding portion 14 of the connecting portion 10 is substantially pushed to the root position in a state where the chain terminal T is supported by the terminal support wall 4. Further, as shown in FIG. 3, when the connecting portion 10 is disconnected from the chained terminal T, the entire connecting portion 10 is held in the connector housing 1 by the tip of the protruding portion 14 being stuck into the back wall of the holding portion 18. Is done.

保持部18を構成する凹み部分の幅方向両側壁は短絡防止壁19となっている。すなわち、両短絡防止壁19は、切り離された連結部10と両端子5との間に位置することで、端子5同士が連結部10によって不用意に短絡されてしまう事態を回避している。また、対向する両短絡防止壁19の間は、切り離された連結部10の両圧入縁13が短絡防止壁19に食い込むことができるような間隔に設定されている。   Both side walls in the width direction of the recessed portion constituting the holding portion 18 are short-circuit prevention walls 19. That is, the two short-circuit prevention walls 19 are located between the disconnected connecting portion 10 and both terminals 5, thereby avoiding a situation where the terminals 5 are inadvertently short-circuited by the connecting portion 10. In addition, an interval between the opposing short-circuit prevention walls 19 is set such that both press-fitting edges 13 of the separated connecting portion 10 can bite into the short-circuit prevention wall 19.

次に、上記のように構成された本実施例の作用効果を説明する。コネクタハウジング1に各連鎖状端子Tを組み込む場合には、各連鎖状端子Tの第1タブ部6側から第2フード部内へ進入させるとともに、両第1タブ部6を対応する端子差し込み孔17へ適合させて圧入する。そして、幅広部8がストッパ面16に当接すれば、各端子5は端子差し込み孔17に対して正規深さまで差し込まれたことになる。この状態では、抜け止め爪9が端子差し込み孔17の孔壁に食い込むため、圧入による保持と併せて端子5の抜け止めがさらに強化される。   Next, the function and effect of the present embodiment configured as described above will be described. When the chained terminals T are assembled into the connector housing 1, the chained terminals T are caused to enter the second hood portion from the first tab portion 6 side and the first tab portions 6 are inserted into the corresponding terminal insertion holes 17. Press fit to fit. And if the wide part 8 contact | abuts to the stopper surface 16, each terminal 5 will be inserted in the terminal insertion hole 17 to the regular depth. In this state, since the retaining claw 9 bites into the hole wall of the terminal insertion hole 17, the retaining of the terminal 5 is further strengthened together with the holding by press fitting.

次に、予め設定された短絡パターンに基づいて連結部10を切り離すべき連鎖状端子Tが選択される(本実施例の場合、図3における幅方向の両端に位置する連鎖状端子T)。選択された連鎖状端子Tにおいては、連結部10の押込み縁12に図示しない切断用治具が当接されて押込みがなされる。これにより、薄肉部11が分断され両端子5から切り離された連結部10は、押圧状態のまま保持部18内を前進し、突入部14の先端が保持部18の奥壁に突き刺さる。この状態では、突入部14のやじり形状により、保持部18の奥壁内に引っ掛かりを持って食い込むため、連結部10は抜け止めされた状態で保持される。また、連結部10自体も突入部14の圧入に加えて、圧入縁13においても圧入されるため、連結部10自体の保持力も高められる。   Next, the chain terminal T which should disconnect the connection part 10 based on the preset short circuit pattern is selected (in the case of a present Example, the chain terminal T located in the both ends of the width direction in FIG. 3). In the selected chained terminal T, the cutting edge (not shown) is brought into contact with the pushing edge 12 of the connecting portion 10 and pushed. Thereby, the connection part 10 which the thin part 11 was parted and cut | disconnected from both the terminals 5 advances the inside of the holding | maintenance part 18 with a press state, and the front-end | tip of the protrusion part 14 pierces the inner wall of the holding | maintenance part 18. In this state, the linking portion 10 is held in a state where it is prevented from being pulled out because it is caught in the inner wall of the holding portion 18 due to the twisted shape of the entry portion 14. Further, since the connecting portion 10 itself is press-fitted at the press-fitting edge 13 in addition to the press-fitting of the rushing portion 14, the holding force of the connecting portion 10 itself is also increased.

さらに、両圧入縁13及び突入部14は共にくさび形状に形成されていることから、これらの圧入に伴って端子支持壁4の肉は両端子側に寄せられる。この結果、端子5に対する圧接力が高められて保持力が向上する。   Furthermore, since both the press-fit edges 13 and the protrusions 14 are both formed in a wedge shape, the thickness of the terminal support wall 4 is brought closer to the both terminals with the press-fitting. As a result, the pressure contact force against the terminal 5 is increased and the holding force is improved.

かくして、本実施例によれば、連鎖状端子Tから切り離された連結部10がコネクタハウジング1の保持部18に突き刺さって保持されるため、連結部10がずれ動き、これが原因で端子5同士が不用意に短絡してしまう事態を確実に回避することができる。   Thus, according to the present embodiment, since the connecting portion 10 separated from the chained terminal T is stuck and held in the holding portion 18 of the connector housing 1, the connecting portion 10 moves and causes the terminals 5 to move together. It is possible to reliably avoid a situation where a short circuit is accidentally short-circuited.
