Reference numeral 1 denotes an upper case, 2 denotes a lower case, and in the case, as shown in FIGS. 11A and 11B, a bus bar composed of a plurality of bus bars (circuit conductors) 3 having a desired circuit pattern and an insulating plate 4. A wiring board 5 is housed. In the upper case 1 or the lower case 2, a large number of electric parts such as the fuse 6, the relay 7, the circuit breaker 8 are mounted, and a plurality of connector insertion portions 9 are provided.

【0003】 コネクタ挿着部9には、前記ブスバー3から一体に形成されたタブ10がコネ クタ端子として収容配列されており、ワイヤハーネス(図示せず)の端末に装着 された外部のコネクタ11と嵌合されて、内部の雌端子12とタブ10との電気 的接続が行われる。A tab 10 integrally formed from the bus bar 3 is housed and arranged in the connector insertion portion 9 as a connector terminal, and an external connector 11 attached to a terminal of a wire harness (not shown) is arranged.

Then, by overcoming this and elastically returning, the locking projection 15 engages with the locking hole 14 as shown in FIG. 11B.

【0006】 しかし、コネクタ11の極数(雌端子12の本数)が多くなると、嵌合力が高 まるのと反対にロック時の感触が弱まり、作業者がこれを感覚的に確認しにくい こと、および結合すべきコネクタの数が極めて多いこと、などのために図11( a)のような半嵌合または不完全嵌合状態で看過され、各種制御機器の誤作動の 原因となる点が問題となっていた。とくに、エアバック装置のような安全装置で はこのような事態は許されない。However, when the number of poles of the connector 11 (the number of female terminals 12) is increased, the fitting force is increased and the feel at the time of locking is weakened, and it is difficult for an operator to visually check this. Also, because of the extremely large number of connectors to be connected, it is overlooked in the half-fitted state or incompletely fitted state as shown in FIG. 11 (a), which causes a malfunction of various control devices. It was. In particular, such a situation is not allowed with a safety device such as an airbag device.

【0007】 本考案は、上記の問題点に着目してなされたもので、コネクタの不完全嵌合を 事前に検知し、これを未然に防止することができる半嵌合検知機構付コネクタを 提供し、以て半嵌合検知機構付コネクタを備えた電気的接続の信頼性の高い電気 接続箱を製作できるようにする。The present invention has been made in view of the above problems, and provides a connector with a half-fitting detection mechanism capable of detecting incomplete fitting of the connector in advance and preventing it from occurring. Thus, it is possible to manufacture an electrical connection box having a connector with a half-fitting detection mechanism and having high electrical connection reliability.

【考案の実施の形態】[Embodiment of device]

以下、本考案の実施の形態の具体例を図面を参照して具体的に説明する。 図1において、Aは電気接続箱、B1 ,B2 (代表して示す場合はB、以下同 様である)は外部のコネクタ、Cは二つのコネクタBの嵌合状態の良否を検知す るチェック用コネクタを示す。なお、従来例(図10参照)におけるヒューズ、 リレー、サーキットブレーカなどの電気部品やこれらの回路を構成するブスバー は既知の構成に従えばよいので、図示を省略する。Hereinafter, specific examples of embodiments of the present invention will be specifically described with reference to the drawings. In FIG. 1, A is an electric junction box, B 1 and B 2 (B in the case of being representative, B is the same hereinafter) is an external connector, and C is a connection state of two connectors B. Shows a check connector. The electrical parts such as fuses, relays, circuit breakers, etc., and the busbars forming these circuits in the conventional example (see FIG. 10) may follow a known configuration, and are not shown.

【0012】 電気接続箱Aのケース20の上部には二つのコネクタB(B1 ,B2 )に対応 するコネクタ挿着部21(211 ,212 )とともにチェック用コネクタCに対 応するチェック用コネクタ挿着部22が設けられている。各コネクタBは一側面 に係止孔24を設けたロッキングアーム23を有し、コネクタ挿着部21の側面 21aには上記係止孔24に係合する係止突起25が設けられている。 これらのロック手段は従来の構成と同様であり、例えばコネクタB1 とコネク タ挿着部211 はいわゆる相対向して嵌合される一対のコネクタを構成する。On the upper part of the case 20 of the electrical junction box A, there is a connector insertion part 21 (21 1 , 21 2 ) corresponding to two connectors B (B 1 , B 2 ) and a check corresponding to a check connector C. The connector insertion portion 22 is provided. Each connector B has a locking arm 23 having a locking hole 24 on one side surface, and a side surface 21a of the connector insertion portion 21 is provided with a locking projection 25 that engages with the locking hole 24. These locking means are the same as in the conventional structure, and for example, the connector B 1 and the connector insertion portion 21 1 form a so-called pair of connectors that are fitted so as to face each other.

【0013】 各コネクタ挿着部21の側面21aには、係止突起25を挟んで一対の嵌合検 知用端子26,26が添設されている。そして、この一対の嵌合検知用端子26 ,26と共にスイッチ手段を構成する短絡用弾性接触子27が上記ロッキングア ーム23の自由端部の裏面に装着されている。A pair of fitting detection terminals 26, 26 is attached to the side surface 21 a of each connector insertion portion 21 with the locking projection 25 interposed therebetween. A short-circuit elastic contactor 27, which constitutes a switch together with the pair of fitting detection terminals 26, 26, is attached to the back surface of the free end of the locking arm 23.

【0014】 この短絡用弾性接触子27は図2(a),(b)に示すように、弧状に湾曲し た小片の一側縁に切欠27aを設けてなり、ロッキングアーム23に設けた差込 溝28に差し込み、その係止爪28aと切欠27aとの係合により係止されてい る。As shown in FIGS. 2 (a) and 2 (b), this short-circuit elastic contactor 27 is provided with a notch 27 a at one side edge of a small piece curved in an arc shape, and is provided with a notch 27 a provided on the locking arm 23. It is inserted into the insertion groove 28 and is locked by the engagement of the locking claw 28a and the notch 27a.

【0015】 29(291 ,292 ,293 )は嵌合検知回路Dを形成するブスバーであり 、ケース内の絶縁板30(図8参照)に配設されている。 ブスバー291 は、両端に起立タブ(31,26)を有し、一方のタブはチェ ック用端子31としてケース20(または絶縁板30)に設けられた端子挿通孔 20aを貫通してチェック用コネクタ挿着部22内にのび、他方のタブは同様に 端子挿通孔20aを貫通してコネクタ挿着部211 の側面21aに沿って延び、 前記一対の嵌合検知用端子26の一方を構成している。同様に、ブスバー292 の両端の起立タブ(26,26)はそれぞれコネクタ挿着部211 ,212 の嵌 合検知用端子を構成している。また、ブスバー293 の両端の起立タブ(26, 31)は、その一方のタブがコネクタ挿着部212 の嵌合検知用端子を、他方が コネクタ挿着部22のチェック用端子を構成している。Reference numeral 29 (29 1 , 29 2 , 29 3 ) is a bus bar forming the fitting detection circuit D, and is arranged on an insulating plate 30 (see FIG. 8) in the case. The bus bar 29 1 has standing tabs (31, 26) at both ends, and one tab passes through a terminal insertion hole 20a provided in the case 20 (or the insulating plate 30) as a check terminal 31 and is checked. The other tab similarly extends through the terminal insertion hole 20a and extends along the side surface 21a of the connector insertion portion 21 1 so that one of the pair of fitting detection terminals 26 is I am configuring. Similarly, the standing tabs (26, 26) at both ends of the bus bar 29 2 respectively constitute the fitting detection terminals of the connector insertion portions 21 1 , 21 2 . As for the standing tabs (26, 31) at both ends of the bus bar 29 3 , one tab constitutes a fitting detection terminal of the connector insertion portion 21 2 and the other tab constitutes a check terminal of the connector insertion portion 22. ing.

【0016】 上記構成において、図3(a)に示すように、たとえば外部のコネクタB1 が 対応するコネクタ挿着部211 に完全に嵌合されていない状態では、そのロッキ ングアーム23が係止突起25に乗り上げ、短絡用弾性接触子27が嵌合検知用 端子26と接触しないから、前記ブスバー291 とブスバー292 とは導通しな い。 そして、図3(b)のように、コネクタB1 の嵌合が完全になされると、ロッ キングアーム23は側面21a側に弾性復帰して、その係止孔24に係止突起2 5が係合してコネクタB1 はコネクタ挿着部211 にロックされる。同時に、短 絡用弾性接触子27が一対の嵌合検知用端子26,26と接触するから、二つの ブスバー291 ,292 が導通する。In the above structure, as shown in FIG. 3A, for example, when the external connector B 1 is not completely fitted to the corresponding connector insertion portion 21 1 , its locking arm 23 is locked. Since the short-circuiting elastic contactor 27 rides on the protrusion 25 and does not come into contact with the fitting detecting terminal 26, the busbar 29 1 and the busbar 29 2 are not electrically connected. Then, as shown in FIG. 3B, when the connector B 1 is completely fitted, the locking arm 23 elastically returns to the side surface 21 a side, and the locking projection 24 is fitted into the locking hole 24. When engaged, the connector B 1 is locked to the connector insertion portion 21 1 . At the same time, since the short-circuit elastic contactor 27 contacts the pair of fitting detection terminals 26, 26, the two bus bars 29 1 , 29 2 are electrically connected.

【0017】 このように、各コネクタ挿着部21と外部のコネクタBのスイッチ手段を構成 する一対の嵌合検知用端子26,26と短絡用弾性接触子27とは、図4に示す ように、嵌合検知回路Dに対して直列に接続されているから、コネクタB1 とB 2 の何れか一つでも不完全嵌合状態にあれば、該回路Dは導通しない。 したがって、たとえば警報ランプを備えたチェック用コネクタCをチェック用 コネクタ挿着部22に嵌合することにより、その点灯の有無からコネクタBの嵌 合状態の良否を電気的に検知し、これを未然に防止することができる。As described above, the connector insertion portion 21, the pair of fitting detection terminals 26, 26 and the short-circuiting elastic contactor 27, which constitute the switch means of the external connector B, are as shown in FIG. , The connector B is connected in series to the fitting detection circuit D.1And B 2 If any one of them is in the incompletely fitted state, the circuit D does not conduct. Therefore, for example, by fitting the check connector C equipped with an alarm lamp into the check connector insertion portion 22, it is possible to electrically detect the good or bad of the fitted state of the connector B from the presence or absence of the lighting, and to check this. Can be prevented.

【0018】 以上は二つのコネクタ挿着部211 ,212 にスイッチ手段を設けた例につい て説明したが、使用目的に応じてその数を増やすことができる。また、嵌合検知 回路Dは、ブスバーのほかプリント配線板、フレキシブルプリント配線板などの 既知の配線板に設けてもよく、或いは電気接続箱を構成するケース20の内面に 直接形成してもよい。Although the example in which the switch means is provided on the two connector insertion portions 21 1 and 21 2 has been described above, the number can be increased according to the purpose of use. Further, the fitting detection circuit D may be provided on a known wiring board such as a printed wiring board or a flexible printed wiring board in addition to the bus bar, or may be directly formed on the inner surface of the case 20 constituting the electric junction box. .

【0019】 図5に示す他の実施例は、前記合成樹脂製のロッキングアーム23に替えて、 弾性金属板製のロッキングアーム23′としたものである。 このロッキングアーム23′は、折り曲げ形成した取付基板32をコネクタ挿 着部21の側面21aの上端に設けた差込溝34に差し込んで、係止孔33と係 止爪35の係合により係止する。本実施例の場合には、ロッキングアーム23′ が金属製であるから、その弾性接触圧を高くし、ロック作業時の感触を良くする と共に、前記一対の嵌合検知用端子26,26との電気的接続を一層確実にする ことができる。In another embodiment shown in FIG. 5, the rocking arm 23 made of an elastic metal plate is used instead of the rocking arm 23 made of the synthetic resin. In this locking arm 23 ′, the bent mounting substrate 32 is inserted into the insertion groove 34 provided at the upper end of the side surface 21 a of the connector insertion portion 21, and the locking hole 33 and the locking claw 35 engage with each other. To do. In the case of the present embodiment, since the locking arm 23 'is made of metal, its elastic contact pressure is increased to improve the feel at the time of locking work, and at the same time, it can be connected to the pair of fitting detection terminals 26, 26. The electrical connection can be made more reliable.

【0020】 図6および図7に示す別の実施例は、一対の嵌合検知用端子26,26をコネ クタ挿着部21の内側面21bに沿って添設し、対応する短絡用弾性接触子27 を外部のコネクタBの差込溝36に装着したものである。本実施例の場合には、 第1実施例とは異なり、スイッチ手段を構成する嵌合検知用端子26と短絡用弾 性接触子27が、コネクタBの嵌合および使用状態においてコネクタ挿着部21 の内部に位置するので、外気による腐食等の影響を受けにくく、安定な電気的接 続状態が持続する。In another embodiment shown in FIGS. 6 and 7, a pair of fitting detection terminals 26, 26 are attached along the inner side surface 21b of the connector insertion portion 21, and the corresponding short-circuit elastic contacts are provided. The child 27 is mounted in the insertion groove 36 of the external connector B. In the case of the present embodiment, unlike the first embodiment, the fitting detection terminal 26 and the short-circuiting elastic contactor 27, which constitute the switch means, have the connector insertion portion when the connector B is fitted and used. Since it is located inside 21, it is unlikely to be affected by corrosion by the outside air, and a stable electrical connection state is maintained.

【0021】 図8および図9(a),(b)に示す更に別の実施例は、嵌合検知回路D′を 、弾性を有する導電性ゴムよりなる回路導体37(371 ,372 )と上下二層 のブスバー294 ,295 とから形成し、スイッチ手段を該回路導体37に設け たスイッチ部38とブスバー294 とから形成したものである。In yet another embodiment shown in FIGS. 8 and 9A and 9B, the fitting detection circuit D'is composed of a circuit conductor 37 (37 1 , 37 2 ) made of elastic conductive rubber. And busbars 29 4 and 29 5 which are two layers above and below, and the switch means is formed by a switch portion 38 provided on the circuit conductor 37 and a busbar 29 4 .

【0022】 各回路導体37は、図9(a),(b)に拡大して示されるように、隆起して 形成されたキャップ状の押しボタン38aとこれから下向きに延びる棒状突起3 8bとからなるスイッチ部38を有する。このスイッチ部38は各コネクタ挿着 部211 ,212 の底部21cに設けた孔21dに出没可能に挿着され、また、 回路導体37は棒状突起38bに対する孔30aを有する第1層の絶縁板30に 支持されている。As shown in the enlarged view of FIGS. 9 (a) and 9 (b), each circuit conductor 37 includes a cap-shaped push button 38a formed in a raised shape and a bar-shaped protrusion 38b extending downward from the cap-shaped push button 38a. It has a switch section 38. The switch portion 38 is removably inserted into a hole 21d provided in the bottom portion 21c of each of the connector insertion portions 21 1 and 21 2 , and the circuit conductor 37 has a hole 30a for the rod-shaped projection 38b. It is supported by the plate 30.

【0023】 一方の回路導体371 はコネクタ挿着部211 とチェック用コネクタ挿着部2 2との間に配設されて、該挿着部22における一方のチェック用端子31′の下 端部に形成された弾性接触片31aに接触している。他方の回路導体372 は、 下方に折り返され、その折り返し端37aはケース20の底部におけるリブ39 に支持されて、下層のブスバー295 と接触している。One circuit conductor 37 1 is arranged between the connector insertion portion 21 1 and the check connector insertion portion 22 and the lower end of one of the check terminals 31 ′ in the insertion portion 22. It contacts the elastic contact piece 31a formed in the section. The other circuit conductor 37 2 is folded back downward, and its folding end 37 a is supported by the rib 39 at the bottom of the case 20 and is in contact with the bus bar 29 5 in the lower layer.

【0024】 上記構成において、図9(b)に示すように、たとえば外部のコネクタB1 ′ が完全にコネクタ挿着部21に嵌合されて、ロッキングアーム40の係止突起4 1が係止孔42に係合してロックされたときに、コネクタB1 ′の底部が押しボ タン38aを押し下げて、その棒状突起38bが上層のブスバー294 と接触し 、チェック用端子31′とブスバー294 とが導通する。以下、第1の実施例の 場合と同様に、コネクタ挿着部211 ,212 に嵌合される全ての外部のコネク タB(B′…)の嵌合、ロック状態の良否をチェック用コネクタC′をチェック 用コネクタ挿着部22に嵌合することにより電気的に検知することができる。In the above structure, as shown in FIG. 9B, for example, the external connector B 1 ′ is completely fitted into the connector insertion portion 21, and the locking protrusion 41 of the locking arm 40 is locked. engages the hole 42 when it is locked, the connector B 1 'by depressing the bottom pushbutton 38a of contact that the rod-like protrusion 38b is an upper bus bar 29 4, check terminal 31' and the bus bar 29 Conducts with 4 . Hereafter, as in the case of the first embodiment, for checking the fit and lock state of all the external connectors B (B '...) Fitted to the connector insertion parts 21 1 and 21 2 By fitting the connector C'into the check connector insertion portion 22, it can be detected electrically.

【0025】 この第4実施例の場合には、スイッチ手段として第1ないし第3具体例のよう な嵌合検知用端子26や短絡用弾性接触子27を要しないので、外部コネクタB やコネクタ挿着部21の外形を従来と何ら変える必要がなく、またスイッチ手段 も内蔵されるから、外力による破損などのおそれが少ない。In the case of the fourth embodiment, since the fitting detecting terminal 26 and the short-circuiting elastic contact 27 as in the first to third embodiments are not required as the switch means, the external connector B and the connector insertion There is no need to change the outer shape of the attachment portion 21 from the conventional one, and since the switch means is also incorporated, there is little risk of damage due to external force.

【0026】 以上は相対向して嵌合される一対のコネクタを構成する外部のコネクタBとコ ネクタ挿着部21のうち、一方のコネクタ挿着部21がケース20と一体に設け てある例について説明したが、該コネクタ挿着部21をケース20から分離した 通常の一対の雌,雄コネクタに適用できることは容易に理解されるであろう。The above is an example in which one of the connector insertion portion 21 and the connector insertion portion 21 of the external connector B and the connector insertion portion 21 which form a pair of connectors fitted to face each other is provided integrally with the case 20. However, it will be easily understood that the connector insertion portion 21 can be applied to a normal pair of female and male connectors separated from the case 20.

【考案の効果】[Effect of device]

以上説明したように、本考案によれば、相互間のロック手段を備えた一対のコ ネクタは、完全嵌合しなければ、一対の嵌合検知用端子が短絡用弾性接触子と接 触せず、従ってスイッチ手段が閉成しないので、不完全嵌合であることを確実に 検知することができる(請求項1,2,3)。 従って、上記半嵌合検知機構付コネクタを電気接続箱に利用すると共に、電気 接続箱における複数のコネクタ挿着部のうち、選ばれた全てのコネクタ挿着部に 相手側のコネクタが完全に嵌合、ロックされたときにはじめて導通する嵌合検知 回路を設けることにより、コネクタの半嵌合状態を事前にチェックし、これを確 実に防止することができ、電気的接続の信頼性の高い電気接続箱を提供すること が可能となる。 As described above, according to the present invention, the pair of connectors provided with the interlocking means do not allow the pair of mating detection terminals to come into contact with the elastic contact for short circuit unless they are completely mated. Therefore, since the switch means is not closed, it is possible to reliably detect incomplete fitting (claims 1, 2, 3). Therefore, the connector with the half-fitting detection mechanism is used for the electrical connection box, and the mating connector is completely fitted to all of the connector insertion portions selected from the plurality of connector insertion portions in the electrical connection box. In this case, by providing a mating detection circuit that conducts only when it is locked, it is possible to check the half mated condition of the connector in advance and prevent this accurately, and to ensure reliable electrical connection. It is possible to provide a junction box.
