Description

【0001】
【産業上の利用分野】
この発明は、自動車、家電製品等に使用される電気コネクタ、特に端子金具を挿入可能にした仮結合状態にリテーナを置きうる電気コネクタに関するものである。
【0002】
【従来の技術】
従来この種の電気コネクタとしては、例えば、特開平5−226025号公報に開示されたものがある。これによれば電気コネクタは合成樹脂で射出成形等の手段で成形されており、図11から図13に示すように、ハウジング10とリテーナ20とがバンドヒンジ30を介して一体に形成されている。ハウジング10内には端子収容室40があり、ここに端子金具50を係止する可撓係止片41およびリテーナ20を挿入させる開口42が形成されている。
【0003】
リテーナ20には、端子係止突起21、本係止突起22が形成され、端子係止突起21には仮係止突起23が形成されている。端子金具50が挿入される以前において、リテーナ20がバンドヒンジ30でハウジング10から離れた状態で積み重ねられ、移動させられたときには、電気コネクタが互いに絡み合ったりするため、リテーナ20が開口42に差し込まれ、バンドヒンジ30の弾撥性で仮係止突起23が開口42の周縁と係止し図12のような仮結合状態で集積され移動される。仮係止突起23は、図11に示すように挿入方向および離脱方向にテーパ面23aが形成され開口42幅より幾分大きくされたこの部分が通過し易くされている。
【0004】
仮結合状態の電気コネクタは、端子金具50が端子収容室40内に挿入され、可撓係止片41と係止し、次いでリテーナ20が押し込まれ、端子係止突起21が端子金具50を押さえ込み、本係止突起22が開口42の周縁に係止されて組み付けが完成する。
【0005】
【発明が解決しようとする課題】
しかしながら、バンドヒンジ30の弾撥性を利用してリヤホルダ20を開口42の周縁に係止しているだけのため、集積移動の過程で、リヤホルダ20が押され、仮結合状態からより端子収容室40内に押し込まれ、図13のように端子係止突起21が開口42の周縁と係止して斜めに挿入されたままになるものがあった。このため端子金具50の挿入に際して端子金具50が可撓係止片41と係止する所定位置まで挿入できず、組み付け不良が発生したり、修正のため組み付け工数が増加するという問題点があった。
【0006】
そこで、この発明の目的は、集積移動の過程でも他のものに絡み付くことがない様にリテーナが仮結合状態のままで、端子金具の挿入組み付けが確実で容易な電気コネクタを提供することにある。
【0007】
【課題を解決するための手段】
この目的を達成するために、請求項1の発明は、コネクタハウジングに少なくとも一個の端子収容室が形成され、該端子収容室に対応してリテーナが前記コネクタハウジングにバンドヒンジを介して一体に形成され、前記リテーナの仮結合状態で端子金具が前記端子収容室に挿入され可撓係止片に係止された後、前記リテーナで前記端子金具を押圧固定する本結合状態にする電気コネクタにおいて、
前記端子収容室に連通し前記リテーナを挿入させ係止させて前記端子金具を押圧固定状態にさせる開口を前記コネクタハウジングに形成し、前記リテーナを仮結合状態にするリブを前記開口の壁面に形成し、前記リテーナを前記開口と係止させて本結合状態にさせる切欠部を前記リブに形成し、前記端子収容室方向への押圧により前記リブを乗り越える第一突起と、該第一突起との間に前記リブを挟んで位置させた仮結合状態とし、かつ押し込み、前記切欠部を通過させ、押しやって本結合状態にさせる第二突起とを前記リテーナに押しやり方向にずらして形成したことを特徴とする電気コネクタとしている。
【0008】
また、請求項2の発明は、請求項1において、前記リブは前記リテーナ仮結合状態にさせる前記端子収容室への挿入方向に対して直交する平行二面を有し、前記第一突起は前記リブを乗り越え容易にするテーパ面と前記仮結合状態で前記リブと平行に対面する対向面とを有し、前記第二突起は前記仮結合状態で前記リブと平行に対面する対向面を有することを特徴とする電気コネクタとしている。
【0009】
また、請求項3の発明は、請求項1または2において、前記リテーナの少なくとも2個が一体に連結されて連結リテーナを形成し、該連結リテーナのうちの少なくとも2個のリテーナの対向側あるいは反対向側に前記第一突起および前記第二突起を形成したことを特徴とする電気コネクタとしている。
【0010】
さらに、請求項4の発明は、請求項1または2において、前記リブに、前記第突起の前記端子金具挿入方向先端と係合し、仮結合状態を維持させる仮結合保持部を形成したことを特徴とする電気コネクタとしている。
【0011】
【発明の実施の形態】
以下、この発明の実施の形態を図面に基づいて説明する。
【0012】
図1〜図10まではこの発明の実施の形態の一例である。従来と同一ないし均等な部位または部材については同一符号を付して重複した説明を省略する。
【0013】
コネクタハウジング10には少なくとも1個の端子収容室40が形成されており、ここに示される電気コネクタでは、コネクタハウジング10に、端子金具50をそれぞれに挿入できる5個の端子収容室40を下段に3個水平に、上段に2個垂直に有している。
【0014】
この端子収容室40に対応してリテーナ60がコネクタハウジング10にバンドヒンジ30を介して一体に形成されている。リテーナ60は、1個で直接バンドヒンジ30を介してコネクタハウジング10に接続されていても良いが、複数個がまとめられて連結リテーナ70を形成して接続されていても良い。ここでは、少なくとも2個のリテーナ60、すなわちコネクタハウジング10の下側に3個のリテーナ60が、側方に2個のリテーナ60が一体に連結されてそれぞれ連結リテーナ70を形成している。
【0015】
コネクタハウジング10には、端子収容室40に連通しリテーナ60を挿入させ係止させて端子金具50を押圧固定状態にさせる開口42が形成されている。開口42に、リテーナ60を図7のように仮結合状態にするリブ43が形成されている。リブ43は、リテーナ60の仮結合状態にさせる端子収容室40への挿入方向に対して直交する平行二面43a,43bを有し、角を有した矩形断面を呈している。また、このリブ43には、リテーナ60を仮結合状態から本結合状態に移行させ得る切欠部44が形成されている。
【0016】
一方、リテーナ60には、端子収容室40方向への押圧によりリブ43を乗り越える第一突起61と、第一突起61との間にリブ43を緩く挟むように位置させた図7の仮結合状態とし、且つ切欠部44を通過させて図9に示すような本結合状態にさせる第二突起62とが形成されている。第二突起62は、押し込み方向と直交する方向(押しやり方向)で第一突起61とはずれて形成されている。第一突起61が形成されたリテーナ60の部分が通過する開口42の幅は、リテーナ60のこの部分の厚みよりほんのわずかに狭く作られており、強引に押し込むことによって通過し抜けないようにされている。
【0017】
リテーナ60の先端部とリブ43との係合関係は、図10に模式的に拡大して示されている。第一突起61には、リブ43を乗り越え容易にするためのテーパ面61aと仮結合状態でリブ43と平行に対面する対向面61bとが形成されている。また、第二突起62には、仮結合状態でリブ43と平行に対面する対向面62aが形成されている。
【0018】
なお、開口42は図1、図2により明らかであるが、ほぼ長い長方形を呈しており、リブ43に沿ってリテーナ60の長手方向を受け入れる部分と切欠部44で広げられた部分とで構成されている。この開口42の長手方向前後端では、本結合状態でそれぞれ第二突起62の位置する先端部および後端係止部63が係止される。
【0019】
また、図3に示すように、連結リテーナ70は少なくとも2個のリテーナ60が一体に連結されており、このうち少なくとも2個のリテーナ60の同一方向側でなく、対向側あるいは反対向側に第一突起61および第二突起62が形成されている。
【0020】
さらに、図4から図9に示すように、リブ43には、第二突起62の端子金具50の挿入方向先端と係合し、図7に示す仮結合状態を維持させる仮結合保持部43cが形成されている。ここに仮結合保持部43cは、平行面43aより端子収容室40内に突出する段差であるが、壁でも突起でもリテーナ60,70が簡単に仮結合状態を解除せず維持させるものであれば形状は問わない。段差あるいは仮結合保持部43cの高さは、第一突起61と第二突起62との間隔からリブ43の厚さを引いた高さ以下に設定されている。
〈作用〉
次に図6〜図9を用いて端子金具50を押圧固定する方法を説明する。
【0021】
図6に示す電気コネクタは、射出成形によりリテーナ60、連結リテーナ70がバンドヒンジ30を介してハウジング10に一体成形された樹脂製品の状態である。この状態で積み上げ、移動などをすると細く柔らかなバンドヒンジ30の部分で他のものと絡まったりする恐れがある。
【0022】
そこで図6の状態から、連結リテーナ70を端子収容室40方向へ押し込むと、リテーナ60の第一突起61は、そのテーパ面61aにより容易にしかし充分な抵抗を持って開口42のリブ43を乗り越え、リブ43を第二突起62と挟むようになり、図7のように何時でも端子金具50を端子収容室40へ挿入できる仮結合状態となる。リブ43は矩形断面であり、その平行二面43a,43bは対向面61b、62aとそれぞれ平行に対面するため、またバンドヒンジ30の弾撥性のために、少々の力が加わった程度ではさらに端子収容室40へ入り込むことはない。また、この状態で少々手荒に取り扱われても電気コネクタ同士で絡み合うことがない。また、少なくとも2個のリテーナ60の対向側あるいは反対向側に第一突起61、第二突起62を設けたので、移動可能な遊びが少なく、リテーナ60が抜け出る可能性が少なく、仮結合状態をより一層確実に保持する(図2、3参照)。
【0023】
第一突起61,第二突起62を設けることにより仮結合状態を確実に保持し、その状態からリテーナ60が抜け出る可能性は少ないが、この状態で梱包、搬送がなされるとき、他のコネクタに押され、係合が外れてリテーナ60の半挿入状態になるかもしれない。この様なことを一層少なくするために、仮結合保持部43cをリブ43に形成している。
【0024】
次に、図7の状態で端子金具50を端子収容室40内に挿入し、可撓係止片41と係止させ、所定位置に着かせる。この状態でリテーナ60を前方に押しやって第二突起62がリブ43の切欠部44に位置するようにし、さらに端子収容室40に押し込むようにすると、図8に示すようなリテーナ挿入過程となる。
【0025】
さらにリテーナ60を前方へ押しやりながら端子収容室40へ押し込むと、図9に示すようにリテーナ60が端子金具50を押圧固定するとともに、開口42の長手方向前後端でそれぞれ第二突起62の位置するリテーナ60の先端部と後端係止部63を受けて本結合状態とする。また、リブ43に仮結合保持部43cが形成されているコネクタの場合は、リテーナ60をより深く押し込み、この仮結合保持部43cとの係合を解除して本結合状態位置に進める。
【0026】
【発明の効果】
以上説明したように、請求項1の発明は、仮結合状態ではリテーナが抜け出ることもさらに端子収容室へ入り込むこともないため、積み上げ、移動などの取扱中に電気コネクタ同士が絡み合ったり、端子金具の挿入が出来なかったり、失敗したりすることがなく、組み付け作業が容易確実に出来る。
【0027】
請求項2の発明は、請求項1の効果に加えて、小さな力で仮結合状態に出来、しかもその状態を確実に保持することが出来る。
【0028】
請求項3の発明は、請求項1または2の効果に加えて、同一方向に第一突起、第二突起を設けるのに較べてリテーナが抜け出ることが難しく仮結合状態の保持が一層確実となる。
【0029】
請求項4の発明は、請求項1又は2の効果に加え、さらに一層仮結合状態から容易に抜け出てしまうということがなく、仮結合状態の保持が一層確実になる。

[Industrial application fields]
The present invention relates to an electrical connector used for automobiles, home appliances, and the like, and more particularly to an electrical connector in which a retainer can be placed in a temporarily coupled state in which a terminal fitting can be inserted.
[0002]
[Prior art]
Conventionally, as this type of electrical connector, for example, there is one disclosed in JP-A-5-226025. According to this, the electrical connector is formed of synthetic resin by means such as injection molding, and the housing 10 and the retainer 20 are integrally formed via the band hinge 30 as shown in FIGS. . Inside the housing 10 is a terminal accommodating chamber 40 in which a flexible locking piece 41 for locking the terminal fitting 50 and an opening 42 for inserting the retainer 20 are formed.
[0003]
The retainer 20 is formed with a terminal locking protrusion 21 and a main locking protrusion 22, and the terminal locking protrusion 21 is formed with a temporary locking protrusion 23. Before the terminal fitting 50 is inserted, when the retainer 20 is stacked and moved away from the housing 10 by the band hinge 30, the electrical connectors are entangled with each other, so that the retainer 20 is inserted into the opening 42. Due to the elasticity of the band hinge 30, the temporary locking projections 23 are locked to the periphery of the opening 42, and are accumulated and moved in a temporarily coupled state as shown in FIG. 12. As shown in FIG. 11, the provisional locking protrusion 23 is formed with a tapered surface 23 a in the insertion direction and the removal direction so that this portion somewhat larger than the width of the opening 42 can easily pass therethrough.
[0004]
In the electrical connector in the temporarily coupled state, the terminal fitting 50 is inserted into the terminal accommodating chamber 40 and locked with the flexible locking piece 41, then the retainer 20 is pushed in, and the terminal locking projection 21 holds down the terminal fitting 50. The main locking projection 22 is locked to the peripheral edge of the opening 42 to complete the assembly.
[0005]
[Problems to be solved by the invention]
However, since the rear holder 20 is merely locked to the periphery of the opening 42 by utilizing the elasticity of the band hinge 30, the rear holder 20 is pushed during the accumulation movement process, and the terminal accommodating chamber is further moved from the temporarily coupled state. In some cases, the terminal locking projections 21 were pushed into the inner wall 40 and remained inserted obliquely as shown in FIG. For this reason, when the terminal fitting 50 is inserted, the terminal fitting 50 cannot be inserted to a predetermined position where the terminal fitting 50 is locked with the flexible locking piece 41, and there is a problem that an assembly failure occurs or the number of assembling steps increases for correction. .
[0006]
Accordingly, an object of the present invention is to provide an electrical connector in which the terminal fitting can be inserted and assembled reliably and easily while the retainer remains in a temporarily coupled state so that the retainer does not get entangled in the process of accumulation and movement. .
[0007]
[Means for Solving the Problems]
In order to achieve this object, according to the first aspect of the present invention, at least one terminal accommodating chamber is formed in the connector housing, and a retainer corresponding to the terminal accommodating chamber is formed integrally with the connector housing via a band hinge. In the electrical connector to be in a final coupled state in which the terminal fitting is inserted into the terminal accommodating chamber in the temporarily coupled state of the retainer and locked to the flexible locking piece, and then the terminal bracket is pressed and fixed by the retainer .
An opening is formed in the connector housing in communication with the terminal accommodating chamber to lock the terminal fitting by inserting and locking the retainer, and a rib for temporarily connecting the retainer is formed on the wall surface of the opening. A notch for locking the retainer with the opening to be in a fully coupled state is formed in the rib, and a first protrusion that overcomes the rib by pressing toward the terminal accommodating chamber, and the first protrusion A temporary coupling state with the rib interposed therebetween, and a second protrusion that is pushed in, passed through the notch, and pushed into the final coupling state is formed by shifting the retainer in the pushing direction. The electrical connector is a feature.
[0008]
According to a second aspect of the present invention, in the first aspect, the rib has two parallel surfaces orthogonal to an insertion direction into the terminal accommodating chamber that causes the retainer to be temporarily coupled, and the first protrusion is A taper surface for facilitating overcoming the rib and an opposing surface facing the rib in the temporarily coupled state; and the second protrusion has an opposing surface facing the rib in the temporarily coupled state. The electrical connector is characterized by this.
[0009]
According to a third aspect of the present invention, in the first or second aspect, at least two of the retainers are integrally connected to form a connected retainer, and at least two of the connected retainers are opposed to or opposite to each other. The electrical connector is characterized in that the first protrusion and the second protrusion are formed on the opposite side.
[0010]
Furthermore, the invention of claim 4 is the invention according to claim 1 or 2, wherein the rib is formed with a temporary coupling holding portion that engages with the tip end of the first protrusion in the terminal fitting insertion direction and maintains the temporary coupling state. The electrical connector is characterized by
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0012]
1 to 10 show an example of an embodiment of the present invention. Parts or members that are the same as or equivalent to those of the prior art are assigned the same reference numerals, and redundant descriptions are omitted.
[0013]
At least one terminal accommodating chamber 40 is formed in the connector housing 10. In the electrical connector shown here, the connector housing 10 has five terminal accommodating chambers 40 into which the terminal fittings 50 can be respectively inserted. There are three horizontally and two vertically on the top.
[0014]
A retainer 60 is integrally formed with the connector housing 10 via the band hinge 30 so as to correspond to the terminal accommodating chamber 40. One retainer 60 may be directly connected to the connector housing 10 via the band hinge 30, but a plurality of retainers 60 may be connected together to form a connecting retainer 70. Here, at least two retainers 60, that is, three retainers 60 on the lower side of the connector housing 10, and two retainers 60 on the side are integrally connected to form a connected retainer 70.
[0015]
The connector housing 10 is formed with an opening 42 that communicates with the terminal accommodating chamber 40 and inserts and retains the retainer 60 so that the terminal fitting 50 is pressed and fixed. Ribs 43 are formed in the opening 42 to place the retainer 60 in a temporarily coupled state as shown in FIG. The rib 43 has parallel two surfaces 43a and 43b orthogonal to the insertion direction to the terminal accommodating chamber 40 in which the retainer 60 is temporarily connected, and has a rectangular cross section with corners. Further, the rib 43 is formed with a notch 44 capable of shifting the retainer 60 from the temporarily coupled state to the fully coupled state.
[0016]
On the other hand, in the retainer 60, the first protrusion 61 that gets over the rib 43 by pressing toward the terminal accommodating chamber 40 and the first protrusion 61 are positioned so as to sandwich the rib 43 loosely. And a second protrusion 62 is formed which passes through the notch 44 and is brought into a main coupling state as shown in FIG. The second protrusion 62 is formed away from the first protrusion 61 in a direction ( pushing direction ) orthogonal to the pressing direction. The width of the opening 42 through which the portion of the retainer 60 on which the first protrusion 61 is formed passes is made slightly narrower than the thickness of this portion of the retainer 60 and is prevented from passing through by forcibly pushing. ing.
[0017]
The engagement relationship between the distal end portion of the retainer 60 and the rib 43 is schematically enlarged and shown in FIG. The first protrusion 61 is formed with a tapered surface 61a for facilitating overcoming the rib 43 and an opposing surface 61b facing the rib 43 in a temporarily coupled state. The second protrusion 62 is formed with a facing surface 62a that faces the rib 43 in a temporarily coupled state.
[0018]
1 and 2, the opening 42 has a substantially long rectangular shape, and includes a portion that receives the longitudinal direction of the retainer 60 along the rib 43 and a portion that is widened by the notch 44. ing. At the front and rear ends of the opening 42 in the longitudinal direction, the front end portion and the rear end locking portion 63 where the second protrusions 62 are respectively positioned are locked in the combined state.
[0019]
In addition, as shown in FIG. 3, the connecting retainer 70 has at least two retainers 60 integrally connected, and of these, at least two retainers 60 are not on the same direction side but on the opposite side or the opposite side. One protrusion 61 and a second protrusion 62 are formed.
[0020]
Further, as shown in FIGS. 4 to 9, the rib 43 has a temporary coupling holding portion 43c that engages with the distal end of the terminal fitting 50 of the second protrusion 62 in the insertion direction and maintains the temporary coupling state shown in FIG. Is formed. Here, the temporary coupling holding portion 43c is a step protruding into the terminal accommodating chamber 40 from the parallel surface 43a, but the retainers 60 and 70 can easily maintain the temporary coupling state without releasing the temporary coupling state regardless of the wall or the protrusion. The shape does not matter. The height of the step or the temporary coupling holding portion 43 c is set to be equal to or less than the height obtained by subtracting the thickness of the rib 43 from the distance between the first protrusion 61 and the second protrusion 62.
<Action>
Next, a method for pressing and fixing the terminal fitting 50 will be described with reference to FIGS.
[0021]
The electrical connector shown in FIG. 6 is a state of a resin product in which a retainer 60 and a connecting retainer 70 are integrally formed on the housing 10 via the band hinge 30 by injection molding. If they are stacked and moved in this state, they may get tangled with other things at the thin and soft band hinge 30 portion.
[0022]
Then, when the connecting retainer 70 is pushed in the direction of the terminal accommodating chamber 40 from the state of FIG. 6, the first protrusion 61 of the retainer 60 easily gets over the rib 43 of the opening 42 with sufficient resistance by the tapered surface 61a. The rib 43 is sandwiched between the second protrusions 62, and the terminal fitting 50 can be inserted into the terminal accommodating chamber 40 at any time as shown in FIG. The rib 43 has a rectangular cross section, and its parallel two surfaces 43a and 43b face each other in parallel with the opposing surfaces 61b and 62a, and because of the resilience of the band hinge 30, it is further increased to the extent that a little force is applied. It does not enter the terminal accommodating chamber 40. Moreover, even if it is handled a little roughly in this state, the electrical connectors are not entangled with each other. In addition, since the first protrusion 61 and the second protrusion 62 are provided on the opposite side or the opposite side of at least two retainers 60, there is little play that can be moved, and there is little possibility that the retainer 60 will come out. Hold it even more securely (see FIGS. 2 and 3).
[0023]
By providing the first protrusion 61 and the second protrusion 62, it is possible to securely maintain the temporarily connected state, and the retainer 60 is less likely to come out from this state. However, when packing and transporting in this state, It may be pushed and disengaged and the retainer 60 may be half inserted. In order to further reduce such a situation, the temporary coupling holding portion 43 c is formed on the rib 43.
[0024]
Next, in the state of FIG. 7, the terminal fitting 50 is inserted into the terminal accommodating chamber 40, is engaged with the flexible locking piece 41, and is placed at a predetermined position. In this state, when the retainer 60 is pushed forward so that the second protrusion 62 is positioned at the notch 44 of the rib 43 and further pushed into the terminal accommodating chamber 40, the retainer insertion process shown in FIG.
[0025]
When the retainer 60 is further pushed forward and pushed into the terminal accommodating chamber 40, the retainer 60 presses and fixes the terminal fitting 50 as shown in FIG. 9 and the positions of the second protrusions 62 at the longitudinal front and rear ends of the opening 42. The front end portion and the rear end locking portion 63 of the retainer 60 to be engaged are received and brought into the final coupled state. Further, in the case of a connector in which the temporary coupling holding portion 43c is formed on the rib 43, the retainer 60 is pushed deeper, the engagement with the temporary coupling holding portion 43c is released, and the main coupling state position is advanced.
[0026]
【The invention's effect】
As described above, according to the first aspect of the present invention, since the retainer does not come out and does not enter the terminal accommodating chamber in the temporarily coupled state, the electrical connectors are entangled during handling such as stacking and moving, and the terminal fittings. Assembling work can be done easily and reliably without failing to insert or fail.
