Description

【0001】
【発明の属する技術分野】
本発明は、防水用のコネクタハウジングに関する。
【0002】
【従来の技術】
防水コネクタの一般的な構造は、雌ハウジング側では、複数のキャビティの設けられたタワー状の端子収容部の回りに大フード部が設けられる一方、相手の雄ハウジング側では、端子収容部に外嵌される小フード部が設けられた構造であって、雌雄のハウジングが嵌合された場合に、端子収容部の付け根部分の外周に嵌着されたシールリングを小フード部との間で弾性的に挟持することによって、両ハウジングの嵌合周面の間のシールを取るようになっている。
【0003】
一方、端子金具並びにそれを収容するキャビティは漸次小型化される傾向にあり、係る小型化に対応しつつ細かい部位で形状に自由度を増したいような場合には、端子収容部について、キャビティの前止まり壁や側壁の一部を欠落した主部と、その欠落部分の補完部分を備えた補助部との2ピースに分けて製造し、後から一体に組み付けるようにしたものがある。なお、この種の2ピースのコネクタハウジングは、特開2000−294334号等に開示されている。
このように端子収容部が2ピースにされると、その外周面が寸断されたような状態になるため、例えば端子収容部の主部の回りに、連続した周面を備えた環形をなすリング装着壁を形成し、そこにシールリングを装着するといった手当を施す必要がある。
【0004】
【発明が解決しようとする課題】
しかるに、コネクタが高温雰囲気で放置されて使用されるようなものである場合、特に多極でリング装着壁が横長形状となるものでは、長辺側の壁面が撓み変形しやすく、例えば変形した部分ではそこに装着されたシールリングが相手の小フード部に対して押し付けられる場合の密着力が不足し、シール性が損なわれるおそれがあった。
尤も、リング装着壁を厚肉とすれば撓み変形は避けられるが、逆にシールリングの装着面にヒケが生じてシールリングとの間に隙間ができるおそれがあるため、簡単には対応できない。
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、その目的は、リング装着壁の変形を有効に防止するところにある。
【0005】
【課題を解決するための手段】
上記の目的を達成するための手段として、請求項1の発明は、端子金具が挿入されるキャビティが複数設けられた端子収容部の回りには、環形をなすリング装着壁が間隔を開けて形成され、このリング装着壁の外周面にシールリングが装着され、このシールリングの外側に相手側のコネクタハウジングのフード部が嵌合されて、前記シールリングが前記リング装着壁と前記フード部との間で弾性的に挟持されることにより防水が図られるようにしたコネクタハウジングであって、前記リング装着壁の内面には補強用のリブが立てられている構成としたところに特徴を有する。
【0006】
請求項2の発明は、請求項1に記載のものにおいて、前記リブが前記端子収容部の外面からは離間しているところに特徴を有する。
請求項3の発明は、請求項1または請求項2に記載のものにおいて、前記端子収容部が、前記キャビティの側壁等の一部を欠落させた主部と、その欠落部分の補完部分を備えて前記主部に対して後付けされる補助部との2ピースから構成されているところに特徴を有する。
【0007】
【発明の作用及び効果】
<請求項1の発明>
内面側にリブを立てたことでリング装着壁の剛性が高められ、撓み変形することが防止される。リング装着壁に装着されたシールリングを全周にわたって相手部材に強固に密着させることができ、シール性が確保される。
<請求項2の発明>
端子収容部側が引っ張られてキャビティ等に変形を来すといったことが防止される。
<請求項3の発明>
端子収容部が2ピースで構成されたものにも適用できる。
【0008】
【発明の実施の形態】
以下、本発明の一実施形態を図1ないし図7に基づいて説明する。この実施形態ではレバー式の防水コネクタを例示しており、そのうち、図1及び図2に示すような雌側のコネクタハウジング10(以下、雌ハウジングという)に本発明が適用されている。
雌ハウジング10は合成樹脂製であって、図3ないし図6に示すように、ハウジング本体11と、前止まり部材12との2ピースから構成されている。
【0009】
ハウジング本体11には、図3に示すように、正面から見て横方向に扁平となった端子収容部14が形成されている。この端子収容部14には、同正面から見た右側の2/3強の領域に、小雌端子(図示せず)を収容する小キャビティ15Sを設けた小型の端子収容筒16S(以下、小収容筒という)が、図示10個ずつの列となって3段に分かれ、基板17を貫通して形成されている。
各小収容筒16Sの小キャビティ15Sには小雌端子が後方から挿入可能とされ、その底面には小雌端子に一次係止する小ランス18Sが撓み変形可能に形成されているとともに、前壁には、相手の小雄端子(図示せず)のタブが挿入される端子挿入口19Sが形成されている。ただし、この小収容筒16Sでは、先端側のほぼ下半分の壁面が欠落されている。
【0010】
端子収容部14における残りの領域には、大雌端子(図示せず)を収容する大キャビティ15Lを設けた大型の端子収容筒16L(以下、大収容筒という)が、図示4個格子状に配されて、同じく基板17を貫通して形成されている。各大収容筒16Lの大キャビティ15Lには大雌端子が後方から挿入可能とされ、その天井面には大雌端子に一次係止する大ランス18Lが撓み変形可能に形成されているとともに、前壁には、相手の大雄端子(図示せず)のタブが挿入される端子挿入口19Lが形成されている。
なお、この端子収容部14の回りには、基板17の配設位置付近よりも前方の部分を覆うようにして、大フード部20が形成されている。
【0011】
前止まり部材12は同じく合成樹脂製であって、上記した端子収容部14の先端側の外周に嵌着されるキャップ状に形成されている。この前止まり部材12の正面壁における図4の左端の領域には、大収容筒16Lの先端を内側に嵌めて、各大キャビティ15Lの端子挿入口19Lを前面に開口する窓孔22が形成されている。この窓孔22の裏面側の上縁からは、図6に示すように、大ランス18Lの撓み空間24Lに突入してその撓み変形を規制する規制片25Lが突設されている。
【0012】
前止まり部材12の正面壁における残りの領域には、各小収容筒16Sの先端を個別にまたは左右2個まとめて嵌めて、各端子挿入口19Sを前面に開口する通孔27が形成されている。各通孔27の裏面側の下縁からは、図5に示すように、上記した各小収容筒16Sで欠落されているところ(欠落部29)の、先端側の下半分の壁面を構成する補完部28が突設されているとともに、小ランス18Sの撓み空間24Sに突入してその撓み変形を規制する規制片25Sが突設されている。
【0013】
前止まり部材12における正面から見た左側壁の内面には、図6に示すように、下側の後縁寄りの位置に仮係止突起30が、上側のそれよりも前方の位置に本係止突起31がそれぞれ形成されている。
一方、上記した前止まり部材12の左側壁が摺接する左側の上下2個の大収容筒16Lの左側面には、下側に仮係止溝32が、上側に本係止溝33がそれぞれ係止されている。
すなわち、前止まり部材12が端子収容部14に嵌められ、本係止突起31が上側の大収容筒16Lの前面の左側縁に当たる一方、仮係止突起30が仮係止溝32に嵌まってその前縁に手前側への抜け止め状に係止することで、前止まり部材12は仮係止位置に保持される。この仮係止位置では、前止まり部材12に設けられた大小の規制片25L,25Sがそれぞれ対応するランス18L,18Sの撓み空間24L,24Sの手前に留まって、その撓み変形を許容するようになっている。
【0014】
前止まり部材12が上記の仮係止位置からさらにハウジング本体11側に突き当たるまで押し込まれると、仮係止突起30が仮係止溝32の奥方に逃がされる一方、本係止突起31が本係止溝33に嵌まってその前縁に手前側への抜け止め状に係止することで、本係止位置に保持される。この本係止位置では、大小の規制片25L,25Sがそれぞれ対応するランス18L,18Sの撓み空間24L,24Sに進入して、その撓み変形を規制する。それとともに、補完部28が欠落部29に嵌まって各小収容筒16Sが所定形状に形成されるようになっている。
【0015】
また、上記した端子収容部14における大フード部20内の付け根部分の回りには、図3に示すように、横長の環形をなすリング装着壁40が形成されている。このリング装着壁40は、基板17の前面に突出するようにして端子収容部14の外周面との間に所定の間隔を開けて形成されており、その外周面にシールリング41(図2参照)が嵌着されるようになっているとともに、その外側に、相手の雄側のコネクタハウジング50(図2の鎖線参照)の小フード部51が嵌合されるようになっている。
そして、このリング装着壁40の上下の辺の内面には、図3に示すように、前後方向を向いた複数のリブ43が、左右方向に間隔を開けて突設されている。各リブ43の突出端は、端子収容部14の外面、すなわち大小の収容筒16L,16Sの外面から離間して形成されている。
【0016】
本実施形態は上記のような構造であって、その作用を組み付け手順とともに説明する。
雌ハウジング10を組み付ける場合は、まずハウジング本体11に形成されたリング装着壁40の外周面にシールリング41が嵌着される。続いて端子収容部14の先端側に前止まり部材12が嵌められて、まず図7に示すように仮係止位置に保持される。次に、電線の端末に圧着された大小の雌端子が対応するキャビティ15L,15S内に挿入され、各ランス18L,18Sを撓み空間24L,24Sに向けて撓み変形させつつ押し込まれて、各雌端子が正規位置まで押し込まれたところで、ランス18L,18Sが復元変形しつつ対応する雌端子に一次係止する。
【0017】
全雌端子の挿入が完了したら、前止まり部材12がさらに押し込まれて、図2に示すように本係止位置に保持される。これにより、規制片25L,25Sが各ランス18L,18Sの撓み空間24L,24Sに突入してその撓み変形を規制し、もって各雌端子は抜け止め状態に二重係止される。それとともに、小収容筒16S側ではそれぞれ正規形状に形成される。また、前止まり部材12が、シールリング41の外れ止めの機能を果たす。
さらに、雌ハウジング10には、所定のカム溝46の形成されたレバー45が軸47に対して回動可能に支持され、始端位置に保持される。雄ハウジング50にも雄端子が装着される。
【0018】
雌雄のハウジング10,50を嵌合する場合は、図2に示すように両ハウジング10,50を対向させ、初期嵌合させると、雄ハウジング50に設けられたフォロワピン52がカム溝46内に係合し、続いてレバー45を終端位置に向けて回動すると、カム機能によって両ハウジング10,50が互いに引き寄せられて嵌合する。このとき雄ハウジング50の小フード部51が雌ハウジング10側のリング装着壁40の外側に進入し、シールリング41を両者の間で弾縮させて挟持することにより、両ハウジング10,50の嵌合周面の間がシールされる。
【0019】
ここでリング装着壁40は、特にその上下の辺が左右方向に長い形状であり、またヒケができることを回避すべく比較的薄肉に形成されているため、例えばこのコネクタが高温雰囲気で放置されて使用されるような場合には、撓み変形することが懸念される。
その点この実施形態では、リング装着壁40の上下の辺の内面に前後方向を向いたリブ43が形成されているからその剛性が高められ、撓み変形することが防止される。その結果、リング装着壁40に装着されたシールリング41を、全周にわたって雄ハウジング50の小フード部51の内面に対して強固に密着でき、シール性を確保することができる。
また、補強用のリブ43は、敢えて大小の収容筒16L,16Sの外面から離間して形成される設定となっており、これにより成形時において収容筒16L,16Sが引っ張られてその変形を来すといったことが防止される。
【0020】
<他の実施形態>
本発明は上記記述及び図面によって説明した実施形態に限定されるものではなく、例えば次のような実施形態も本発明の技術的範囲に含まれ、さらに、下記以外にも要旨を逸脱しない範囲内で種々変更して実施することができる。
(1)上記実施形態では端子収容部が2ピースにより構成されている場合を例示したが、これに限らず、要はシールリングを装着するリング装着壁が比較的薄肉の環形に形成されている場合全般に適用することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a waterproof connector housing.
[0002]
[Prior art]
On the female housing side, the general structure of the waterproof connector is such that a large hood portion is provided around a tower-like terminal accommodating portion provided with a plurality of cavities, while the mating male housing side is external to the terminal accommodating portion. When the male and female housings are fitted, the seal ring fitted on the outer periphery of the base portion of the terminal accommodating portion is elastic with the small hood portion. Thus, a seal between the fitting peripheral surfaces of both housings is taken.
[0003]
On the other hand, terminal fittings and cavities that accommodate the terminal fittings tend to be gradually reduced in size, and in cases where it is desired to increase the degree of freedom in shape at a fine part while corresponding to such downsizing, the terminal accommodating part is placed in front of the cavity. There are parts that are manufactured in two pieces, a main part that lacks a part of the stop wall or side wall, and an auxiliary part that is provided with a complementary part of the missing part, and is assembled together later. A two-piece connector housing of this type is disclosed in Japanese Patent Application Laid-Open No. 2000-294334.
When the terminal accommodating portion is made into two pieces in this way, the outer peripheral surface thereof is in a state of being cut off. For example, a ring having a continuous peripheral surface around the main portion of the terminal accommodating portion. It is necessary to take care of forming a mounting wall and mounting a seal ring there.
[0004]
[Problems to be solved by the invention]
However, when the connector is left to be used in a high-temperature atmosphere, the wall on the long side is easily bent and deformed, especially when the ring mounting wall has a horizontally long shape, for example, a deformed portion. Then, when the seal ring mounted on the seal ring is pressed against the other small hood portion, there is a fear that the sealing force may be impaired due to insufficient adhesion.
However, if the ring mounting wall is made thick, bending deformation can be avoided, but conversely, there is a possibility that a sink will occur on the mounting surface of the seal ring and a gap may be formed between it and the seal ring.
The present invention has been completed based on the above circumstances, and an object thereof is to effectively prevent deformation of the ring mounting wall.
[0005]
[Means for Solving the Problems]
As a means for achieving the above object, the invention according to claim 1 is characterized in that an annular ring mounting wall is formed at intervals around a terminal accommodating portion provided with a plurality of cavities into which terminal fittings are inserted. A seal ring is mounted on the outer peripheral surface of the ring mounting wall , and a hood portion of the mating connector housing is fitted to the outside of the seal ring, so that the seal ring is connected to the ring mounting wall and the hood portion. The connector housing is designed to be waterproofed by being elastically sandwiched between them, and is characterized in that a reinforcing rib is provided on the inner surface of the ring mounting wall.
[0006]
The invention of claim 2 is characterized in that, in the invention of claim 1, the rib is separated from the outer surface of the terminal accommodating portion.
According to a third aspect of the present invention, in the first or second aspect of the present invention, the terminal accommodating portion includes a main portion in which a part of a side wall or the like of the cavity is missing, and a complementary portion of the missing portion. It is characterized in that it is composed of two pieces with an auxiliary part retrofitted to the main part.
[0007]
[Action and effect of the invention]
<Invention of Claim 1>
Raising the ribs on the inner surface side increases the rigidity of the ring mounting wall and prevents deformation. The seal ring mounted on the ring mounting wall can be firmly adhered to the mating member over the entire circumference, and sealing performance is ensured.
<Invention of Claim 2>
It is possible to prevent the cavity from being deformed due to the terminal accommodating portion being pulled.
<Invention of Claim 3>
The present invention can also be applied to a case in which the terminal accommodating portion is composed of two pieces.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS. In this embodiment, a lever-type waterproof connector is illustrated, and the present invention is applied to a female connector housing 10 (hereinafter referred to as a female housing) as shown in FIGS.
The female housing 10 is made of synthetic resin, and as shown in FIGS. 3 to 6, is constituted by two pieces, that is, a housing main body 11 and a front stop member 12.
[0009]
As shown in FIG. 3, the housing main body 11 is formed with a terminal accommodating portion 14 that is flat in the lateral direction when viewed from the front. The terminal accommodating portion 14 has a small terminal accommodating cylinder 16S (hereinafter referred to as a small-sized terminal cylinder 16S) in which a small cavity 15S for accommodating a small female terminal (not shown) is provided in an area slightly more than 2/3 on the right side when viewed from the front. (Referred to as “accommodating cylinders”), each of which is shown in FIG.
A small female terminal can be inserted into the small cavity 15S of each small accommodating cylinder 16S from the rear, and a small lance 18S that is primarily locked to the small female terminal is formed on the bottom surface so as to be able to bend and deform. Is formed with a terminal insertion slot 19S into which a tab of a mating male terminal (not shown) is inserted. However, in the small accommodating cylinder 16S, the substantially lower half wall surface on the tip side is missing.
[0010]
In the remaining area of the terminal accommodating portion 14, large terminal accommodating cylinders 16L (hereinafter referred to as large accommodating cylinders) provided with large cavities 15L for accommodating large female terminals (not shown) are arranged in a lattice shape in the figure. Similarly, it is formed through the substrate 17. A large female terminal can be inserted into the large cavity 15L of each large accommodating cylinder 16L from behind, and a large lance 18L that is primarily locked to the large female terminal is formed on the ceiling surface so as to be able to bend and deform. The wall is formed with a terminal insertion port 19L into which a tab of a mating male terminal (not shown) is inserted.
A large hood portion 20 is formed around the terminal accommodating portion 14 so as to cover a portion in front of the vicinity of the position where the substrate 17 is disposed.
[0011]
The front stop member 12 is also made of a synthetic resin, and is formed in a cap shape that is fitted to the outer periphery on the distal end side of the terminal accommodating portion 14 described above. In the left end region of FIG. 4 on the front wall of the front stop member 12, a window hole 22 is formed in which the tip of the large accommodating cylinder 16L is fitted inward and the terminal insertion port 19L of each large cavity 15L is opened to the front. ing. As shown in FIG. 6, a restricting piece 25 </ b> L that protrudes into the bending space 24 </ b> L of the large lance 18 </ b> L and restricts the bending deformation is protruded from the upper edge of the rear surface side of the window hole 22.
[0012]
In the remaining area of the front wall of the front stop member 12, through holes 27 are formed in which the front ends of the small accommodating cylinders 16S are individually or collectively fitted to the left and right to open the terminal insertion ports 19S on the front surface. Yes. From the lower edge of the back surface side of each through-hole 27, as shown in FIG. 5, the wall surface of the lower half of the tip side where it is missing in each of the small accommodating cylinders 16S (the missing portion 29) is formed. A supplementary portion 28 is provided in a protruding manner, and a restricting piece 25S that protrudes into the bending space 24S of the small lance 18S and restricts the bending deformation is provided in a protruding manner.
[0013]
On the inner surface of the left side wall as viewed from the front of the front stop member 12, as shown in FIG. 6, a temporary locking projection 30 is located at a position near the lower rear edge, and the main engagement protrusion 30 is located at a position ahead of that on the upper side. Stop protrusions 31 are respectively formed.
On the other hand, the temporary locking groove 32 on the lower side and the main locking groove 33 on the upper side are respectively engaged with the left side surfaces of the two large housing cylinders 16L on the left side where the left side wall of the front stop member 12 is in sliding contact. It has been stopped.
That is, the front stop member 12 is fitted into the terminal accommodating portion 14, and the main locking projection 31 hits the left edge of the front surface of the upper large receiving cylinder 16 </ b> L, while the temporary locking projection 30 is fitted into the temporary locking groove 32. The front stop member 12 is held at the temporary locking position by being locked to the front edge so as to prevent the front edge from coming off. In this temporary locking position, the large and small restricting pieces 25L and 25S provided on the front stop member 12 remain in front of the corresponding bending spaces 24L and 24S of the corresponding lances 18L and 18S so as to allow the bending deformation. It has become.
[0014]
When the front stop member 12 is pushed in from the temporary locking position until it comes into contact with the housing body 11, the temporary locking protrusion 30 is released to the back of the temporary locking groove 32, while the main locking protrusion 31 is connected to the main locking protrusion 31. By being fitted in the stop groove 33 and locked to the front edge thereof so as to prevent it from coming out to the near side, it is held at the main locking position. At the main locking position, the large and small restricting pieces 25L and 25S enter the bending spaces 24L and 24S of the corresponding lances 18L and 18S, respectively, and restrict the bending deformation. At the same time, the complementary portion 28 is fitted into the missing portion 29 so that each small accommodating cylinder 16S is formed in a predetermined shape.
[0015]
Further, as shown in FIG. 3, a ring mounting wall 40 having a horizontally long ring shape is formed around the base portion in the large hood portion 20 in the terminal accommodating portion 14 described above. The ring mounting wall 40 is formed with a predetermined gap between the ring mounting wall 40 and the outer peripheral surface of the terminal accommodating portion 14 so as to protrude from the front surface of the substrate 17, and a seal ring 41 (see FIG. 2). ), And a small hood portion 51 of the mating male connector housing 50 (see the chain line in FIG. 2) is fitted to the outside thereof.
As shown in FIG. 3, a plurality of ribs 43 facing in the front-rear direction are provided on the inner surfaces of the upper and lower sides of the ring mounting wall 40 so as to protrude in the left-right direction. The protruding end of each rib 43 is formed away from the outer surface of the terminal accommodating portion 14, that is, the outer surfaces of the large and small accommodating cylinders 16L and 16S.
[0016]
The present embodiment has the structure as described above, and its operation will be described together with the assembling procedure.
When the female housing 10 is assembled, the seal ring 41 is first fitted on the outer peripheral surface of the ring mounting wall 40 formed on the housing body 11. Subsequently, the front stop member 12 is fitted to the distal end side of the terminal accommodating portion 14, and is first held in the temporary locking position as shown in FIG. Next, large and small female terminals crimped to the ends of the electric wires are inserted into the corresponding cavities 15L and 15S, and the lances 18L and 18S are pushed into the bending spaces 24L and 24S while being bent and deformed. When the terminal is pushed to the normal position, the lances 18L and 18S are primarily deformed and deformed to the corresponding female terminals.
[0017]
When the insertion of all the female terminals is completed, the front stop member 12 is further pushed in and held in the final locking position as shown in FIG. As a result, the restricting pieces 25L and 25S enter the bending spaces 24L and 24S of the lances 18L and 18S to restrict the bending deformation, and thus the female terminals are double-locked in a retaining state. At the same time, the small accommodating cylinder 16S is formed in a regular shape. Further, the front stop member 12 functions to prevent the seal ring 41 from coming off.
Further, a lever 45 formed with a predetermined cam groove 46 is supported on the female housing 10 so as to be rotatable with respect to the shaft 47 and is held at the start position. A male terminal is also attached to the male housing 50.
[0018]
When the male and female housings 10 and 50 are fitted, when the two housings 10 and 50 are opposed to each other and initially fitted as shown in FIG. 2, the follower pin 52 provided on the male housing 50 is engaged in the cam groove 46. Subsequently, when the lever 45 is rotated toward the end position, the two housings 10 and 50 are attracted and fitted to each other by the cam function. At this time, the small hood portion 51 of the male housing 50 enters the outside of the ring mounting wall 40 on the female housing 10 side, and the seal ring 41 is elastically clamped between the two so that the housings 10 and 50 are fitted. The gap between the peripheral surfaces is sealed.
[0019]
Here, the ring mounting wall 40 has a shape in which the upper and lower sides are particularly long in the left-right direction, and is formed to be relatively thin so as to avoid the occurrence of sink marks. For example, this connector is left in a high-temperature atmosphere. When it is used, there is a concern about bending deformation.
In this respect, in this embodiment, since the ribs 43 facing in the front-rear direction are formed on the inner surfaces of the upper and lower sides of the ring mounting wall 40, the rigidity thereof is increased, and bending deformation is prevented. As a result, the seal ring 41 mounted on the ring mounting wall 40 can be firmly adhered to the inner surface of the small hood portion 51 of the male housing 50 over the entire circumference, and sealing performance can be ensured.
Further, the reinforcing rib 43 is set so as to be separated from the outer surfaces of the large and small accommodating cylinders 16L and 16S, and this causes the accommodating cylinders 16L and 16S to be pulled and deformed during molding. Is prevented.
