Abstract

<P>PROBLEM TO BE SOLVED: To make a female contact stably retained without overturning in the cross-sectional face direction in a housing. <P>SOLUTION: This female contact 1 comprises a socket 10 having a male contact housing space. The socket 10 includes a bottom wall 11 and two side walls 12, and the respective side walls 12 have the side wall main body 12a of the male contact insertion port side and an extension part 12b installed at the neighborhood of the upper end of the down stream end part of this male contact insertion direction. While elastic force is given to the side wall main body 12a, a contact part 12x that can come into contact with a male contact is installed. Because the outer side face spacing with regard to the y direction of the side wall 12 is substantially equal to an inside face spacing of the respectively corresponding housing 40 at the extension part 12b and in the vicinity of the bottom wall 11, when the female contact 1 is stored in the housing 40, the respective extension part 12b and the neighborhood of the connection part of the bottom wall 11 in the side wall main body 12a are nearly contacted with the housing 40, respectively. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

本発明は、雄コンタクトをソケットに挿抜自在に収容して電気的に接触させる雌コンタクトに関し、より詳細には、ソケット内に板バネを有さずソケットの内壁で雄コンタクトを挟持する雌コンタクトに関する。   The present invention relates to a female contact in which a male contact is removably received in a socket and electrically contacted, and more particularly to a female contact that does not have a leaf spring in the socket and holds the male contact on the inner wall of the socket. .

雌コンタクトとしては、雄コンタクトの収容空間を画定するソケット内に板バネを有し、板バネとソケットの内壁とによって雄コンタクトを挟持するものと、ソケット内に板バネを有さず、ソケットの内壁によって雄コンタクトを挟持するもの（特許文献１参照）とがある。前者の場合は板バネの弾性力により、後者の場合はソケットの一部に形成された接触部の弾性力により、それぞれ雄コンタクトを所定の接触圧にて導通可能に保持する。つまり、前者は雄コンタクトに弾性力を付与する機能を板バネが担い、後者はソケットに形成された接触部が担う。このため後者におけるソケットには、雄コンタクトに弾性力を付与して確実に保持できるよう、上述の接触部として、内壁の対向間隔が比較的小さい部分を形成する必要がある。   As female contacts, there are plate springs in a socket that defines a housing space for male contacts, and male contacts are sandwiched between the plate spring and the inner wall of the socket, and there are no plate springs in the socket. Some have male contacts sandwiched between inner walls (see Patent Document 1). In the former case, the male contact is held continually at a predetermined contact pressure by the elastic force of the leaf spring, and in the latter case by the elastic force of the contact portion formed on a part of the socket. That is, the former is responsible for the function of applying an elastic force to the male contact, and the latter is the contact portion formed on the socket. For this reason, in the latter socket, it is necessary to form a portion having a relatively small facing distance between the inner walls as the above-mentioned contact portion so that the male contact can be securely held by applying an elastic force.

例えば上記文献における雌コンタクトのソケットは、略矩形の底壁、及び、当該底壁におけるソケット幅方向両端から互いに対向するよう延出した２つの側壁を含む。両側壁は、ソケットの長手方向中心軸に関して対称に、湾曲している。より詳細には、側壁の底壁との接続部から若干上側に、内側に凸となる屈曲部が雄コンタクト挿入方向に沿って形成されている。側壁におけるこの屈曲部より上側が、端部を近接させつつ外側に凸に湾曲し、この湾曲した部分に内側に凸になるよう窪んだ接触部が形成されている。また、対向方向に関する２つの側壁の外側面間隔は、側壁の底壁との接続部近傍において最も大きく、これより上側では当該接続部近傍よりも小さい。
実開平１−１２６０６９号公報 For example, the socket of the female contact in the above document includes a substantially rectangular bottom wall and two side walls extending from the both ends of the bottom wall in the socket width direction so as to face each other. The side walls are curved symmetrically with respect to the longitudinal central axis of the socket. More specifically, a bent portion that protrudes inward slightly is formed along the male contact insertion direction slightly above the connecting portion with the bottom wall of the side wall. The upper side of the bent portion of the side wall is convexly curved outward while the end portions are close to each other, and a concave contact portion is formed in the curved portion so as to be convex inward. In addition, the distance between the outer surfaces of the two side walls in the opposing direction is the largest in the vicinity of the connection portion with the bottom wall of the side wall, and is smaller than the vicinity of the connection portion above this.
Japanese Utility Model Publication No. 1-126069

雌コンタクトは、ハウジング内に格納された状態で使用されるので、対応するハウジングに合った形状に設計する必要がある。上述した雌コンタクトのように、側壁の対向方向に関する外側面間隔が側壁の底壁との接続部近傍において最も大きい場合、一般に、この接続部近傍における外側面間隔をハウジングの内側面間隔と一致させる。このように設計された雌コンタクトがハウジング内に格納されると、ソケットの下部、より詳細にはソケットの底壁及び側壁の底壁との接続部近傍のみがハウジングとほぼ接触し、ソケットの上部はハウジングと接触せずに離隔する。このため、例えばソケット内に収容された雄コンタクトや、雌コンタクトに接続された電線に対して外力がかかった場合などに、この力が雌コンタクトに加わり、雌コンタクトがハウジング内でその横断面方向に横転してしまうことがある。雌コンタクトがハウジング内にて横転すると、接触不良などの問題が生じ得る。   Since the female contact is used in a state of being stored in the housing, it is necessary to design the female contact in a shape suitable for the corresponding housing. When the outer surface spacing in the opposite direction of the side wall is the largest in the vicinity of the connecting portion with the bottom wall of the side wall as in the female contact described above, the outer surface spacing in the vicinity of the connecting portion is generally matched with the inner surface spacing of the housing. . When the female contact designed in this way is housed in the housing, only the lower part of the socket, more specifically, only the vicinity of the connection between the bottom wall of the socket and the bottom wall of the side wall substantially contacts the housing, Are separated without contact with the housing. For this reason, for example, when an external force is applied to the male contact housed in the socket or the electric wire connected to the female contact, this force is applied to the female contact, and the female contact is in the transverse direction in the housing. May overturn. If the female contact rolls over in the housing, problems such as poor contact may occur.

そこで、本発明の目的は、ハウジング内において横断面方向に横転することなく安定して保持される雌コンタクトを提供することである。   SUMMARY OF THE INVENTION An object of the present invention is to provide a female contact that is stably held in a housing without overturning in the cross-sectional direction.

課題を解決するための手段及び効果Means and effects for solving the problems

本発明の雌コンタクトは、ハウジング内に格納可能であると共に、雄コンタクトの収容空間を有するソケットを備えており、前記ソケットが、底壁、及び、前記底壁における雄コンタクト挿抜方向と直交する方向の両端から互いに対向するよう延出した２つの側壁を含み、前記側壁がそれぞれ、前記底壁との接続部近傍を除いた位置に、弾性力を付与しつつ雄コンタクトと接触可能な接触部と、対向方向に関する互いの内側面間隔が前記接触部より大きく、雄コンタクト収容時に雄コンタクトから離隔する拡張部と、を有し、前記拡張部が、前記側壁の延出方向端部近傍にあって、前記拡張部、及び、前記底壁との接続部近傍における、前記対向方向に関する前記側壁の外側面間隔が、それぞれ対応するハウジングの内側面間隔と実質的に等しい。   The female contact of the present invention includes a socket that can be stored in a housing and has a male contact housing space, and the socket is a bottom wall and a direction perpendicular to the male contact insertion / extraction direction of the bottom wall. A contact portion that can contact the male contact while applying an elastic force to a position excluding the vicinity of the connection portion with the bottom wall. Each of the inner side surfaces in the opposite direction is larger than the contact part, and has an extension part that is separated from the male contact when the male contact is accommodated, and the extension part is in the vicinity of the end of the side wall in the extending direction. The outer surface spacing of the side walls in the opposing direction in the vicinity of the connecting portion with the extension portion and the bottom wall is substantially equal to the inner surface spacing of the corresponding housing, respectively. There.

この構成による雌コンタクトがハウジング内に格納されると、ソケットの底壁及び側壁の底壁との接続部近傍に加え、側壁の延出方向端部近傍に設けられた拡張部もまた、ハウジングとほぼ接触する。このようにソケットがその上部及び下部両方においてハウジングとほぼ接触する場合、ソケットの収容空間内に収容された雄コンタクト、または雌コンタクトに接続された電線に外力がかかり、雌コンタクトにその横断面方向の力が加わっても、雌コンタクトのハウジング内での横転が防止される。つまり上記構成によると、雌コンタクトをハウジング内にて安定して保持することができる。   When the female contact according to this configuration is stored in the housing, in addition to the socket bottom wall and the vicinity of the connection portion of the side wall with the bottom wall, the extended portion provided in the vicinity of the end portion in the extending direction of the side wall also includes the housing. Almost touch. In this way, when the socket is almost in contact with the housing at both the upper part and the lower part, external force is applied to the male contact accommodated in the socket accommodating space or the electric wire connected to the female contact, and the female contact is oriented in the transverse direction. Even if this force is applied, the rollover of the female contact in the housing is prevented. That is, according to the above configuration, the female contact can be stably held in the housing.

本発明の雌コンタクトは、前記拡張部が、前記側壁の雄コンタクト挿抜方向末端に設けられていることが好ましい。この構成によると、側壁に拡張部を形成するにあたり、その雄コンタクト挿抜方向末端を適宜の器具で外側に押し広げるなどすればよく、拡張部を比較的簡単に形成することができる。   In the female contact according to the present invention, it is preferable that the extended portion is provided at the end of the side wall in the male contact insertion / extraction direction. According to this configuration, when forming the extended portion on the side wall, the male contact insertion / extraction end may be pushed outward with an appropriate tool, and the extended portion can be formed relatively easily.

本発明の雌コンタクトは、前記接触部及び前記拡張部が、雄コンタクト挿入方向に沿って順に設けられており、前記側壁の延出方向端部における前記対向方向に関する互いの内側面間隔が、前記接触部よりも雄コンタクト挿入口において大きいことが好ましい。この構成によると、ソケット側壁の雄コンタクト挿入口の上記間隔が比較的大きいので、雄コンタクトをソケット内に挿入するときその先端が側壁に当接するのが防止され、雄コンタクトの挿入作業を円滑に行うことができる。つまり、雄コンタクト挿入口では側壁の内側面間隔を雄コンタクトの幅より大きくすることによって雄コンタクトを挿入しやすくすると共に、これより挿入方向下流側にある接触部では側壁の内側面間隔を小さくすることで、雄コンタクトに弾性力を付与しつつこれを挟持し、雄コンタクトとの接続信頼性を高めることができる。   In the female contact of the present invention, the contact portion and the extension portion are provided in order along the male contact insertion direction, and the inner side surface interval with respect to the facing direction at the end portion in the extending direction of the side wall is It is preferable that the male contact insertion opening is larger than the contact portion. According to this configuration, since the above-mentioned distance between the male contact insertion holes on the socket side wall is relatively large, when the male contact is inserted into the socket, the tip of the male contact is prevented from coming into contact with the side wall, and the male contact can be inserted smoothly. It can be carried out. In other words, the male contact insertion opening makes it easier to insert the male contact by making the inner surface interval between the side walls larger than the width of the male contact, and the inner surface interval between the side walls is made smaller at the contact portion downstream in the insertion direction. Thus, the male contact can be sandwiched while applying an elastic force, and the connection reliability with the male contact can be improved.

本発明の雌コンタクトは、前記ソケットが、横断面視において、前記側壁の延出方向に細長であることが好ましい。この構成によると、ソケットにおける側壁の対向方向に沿った長さが比較的小さくなるので、省スペース化に有効である。また、この構成のようにソケットの横断面が細長である場合、ハウジング内での雌コンタクトの安定性が確保されにくく、上述のような横転の問題が顕著になるが、本発明ではこのような場合でも雌コンタクトの横断面方向への横転を防止し、これを安定して保持することができる。   In the female contact according to the present invention, it is preferable that the socket is elongated in the extending direction of the side wall in a cross-sectional view. According to this configuration, the length of the socket along the opposing direction of the side wall is relatively small, which is effective for space saving. In addition, when the socket has a long and narrow cross section as in this configuration, it is difficult to ensure the stability of the female contact in the housing, and the problem of rollover as described above becomes significant. Even in this case, it is possible to prevent the female contact from overturning in the cross-sectional direction and to hold it stably.

以下、本発明の好適な一実施の形態について、図面を参照しつつ説明する。   A preferred embodiment of the present invention will be described below with reference to the drawings.

先ず、図１、図２、図３、及び図４を参照しつつ、本実施形態に係る雌コンタクト１の全体構成について説明する。図１〜図４において互いに直交する矢印ｘ，ｙ，ｚは、それぞれ本実施の形態に係る雌コンタクト１の長手方向、幅方向、上下方向を示す。また、ｘ，ｙ，ｚ方向はそれぞれ、雄コンタクトの挿抜方向、後述する雌コンタクトのソケットにおける側壁の対向方向、及び、ソケットにおける側壁の延出方向と一致する。   First, the overall configuration of the female contact 1 according to the present embodiment will be described with reference to FIGS. 1, 2, 3, and 4. 1 to 4, arrows x, y, and z that are orthogonal to each other indicate the longitudinal direction, the width direction, and the vertical direction of the female contact 1 according to the present embodiment, respectively. The x, y, and z directions coincide with the insertion / extraction direction of the male contact, the opposing direction of the side wall of the socket of the female contact, which will be described later, and the extending direction of the side wall of the socket.

雌コンタクト１は、ｘ方向に沿って、図１及び図２の右側から順に、当該ｘ方向に細長い筒状のソケット１０と、ソケット１０の一端と連結部２０ａを介して接続された導体圧着部２０と、導体圧着部２０の連結部２０ａとは反対側の端部と連結部３０ａを介して接続された絶縁体圧着部３０とを備えている。雌コンタクト１の各部は、いずれも同一の導電性材料、例えば比較的弾性の高い銅合金等からなる。より詳細には、雌コンタクト１の各部は、上記材料からなる１枚の平板を折り曲げるなどして形成されたものである。   The female contact 1 includes a cylindrical socket 10 elongated in the x direction and a conductor crimping portion connected to one end of the socket 10 via a connecting portion 20a in order from the right side of FIGS. 1 and 2 along the x direction. 20 and an insulator crimping portion 30 connected to the end of the conductor crimping portion 20 opposite to the coupling portion 20a via a coupling portion 30a. Each part of the female contact 1 is made of the same conductive material, for example, a copper alloy having relatively high elasticity. More specifically, each part of the female contact 1 is formed by bending one flat plate made of the above material.

ソケット１０は、略長方形平面の底壁１１と、底壁１１の幅方向（ｙ方向）両端から互いに対向するようｚ方向に延出した２つの側壁１２とを含む。これら底壁１１及び２つの側壁１２に囲まれた空間が雄コンタクト収容空間であり、図１及び図２の右側が雄コンタクト挿入口となる。そしてこの挿入口から、ｘ方向に沿って雄コンタクト１００をソケット１０の内に挿抜することができる。また、図１及び図２に示す太矢印Ａは、雄コンタクト１００の挿入方向である。本実施形態の雄コンタクト１００は板状である。   The socket 10 includes a bottom wall 11 having a substantially rectangular plane and two side walls 12 extending in the z direction so as to face each other from both ends in the width direction (y direction) of the bottom wall 11. A space surrounded by the bottom wall 11 and the two side walls 12 is a male contact accommodating space, and the right side of FIGS. 1 and 2 is a male contact insertion opening. Then, the male contact 100 can be inserted into and removed from the socket 10 along the x direction from the insertion port. Moreover, the thick arrow A shown in FIG.1 and FIG.2 is the insertion direction of the male contact 100. FIG. The male contact 100 of this embodiment is plate-shaped.

ソケット１０の底壁１１には、Ａ方向下流側に入れられた切込み１１ｂ（図１参照）を介して一部が下方に突出することにより、ランス１１ａが形成されている。ランス１１ａは、雌コンタクト１を格納する後述のハウジング４０（図５（Ａ），（Ｂ）及び図６参照）に当該雌コンタクト１を係止させるものであり、雌コンタクト１はハウジング４０に係止され、ハウジング４０からの抜け落ちが防止される。   A lance 11a is formed on the bottom wall 11 of the socket 10 by protruding partly downward through a notch 11b (see FIG. 1) inserted downstream in the A direction. The lance 11 a locks the female contact 1 in a housing 40 (see FIGS. 5A, 5 B, and 6) that stores the female contact 1, which will be described later. It is stopped and falling off from the housing 40 is prevented.

ソケット１０の各側壁１２は、図２に示すように、下部が連結部２０ａと接続され、雄コンタクト収容空間の大部分を画定する略矩形の側壁本体１２ａと、側壁本体１２ａのＡ方向下流側末端の上端近傍からＡ方向に向けて連結部２０ａのｘ方向略中央に対応する位置まで延出された略台形の拡張部１２ｂとを含む。拡張部１２ｂの上端は側壁本体１２ａの上端と同一面上にあり、その下端はＡ方向下流側にいくにつれて上方に傾斜している。ｙ方向から見て、側壁本体１２ａの雄コンタクト挿入口側（図２右側）端部、及び、拡張部１２ｂのＡ方向下流側端部は、共に底壁１１に対して垂直である。また、側壁本体１２ａにおける上端近傍のｘ方向略中央には、後に詳述する内側に凸となった接触部１２ｘが形成されている。   As shown in FIG. 2, each side wall 12 of the socket 10 is connected to the connecting portion 20a at the lower part, and has a substantially rectangular side wall body 12a that defines most of the male contact accommodating space, and a downstream side in the A direction of the side wall body 12a. A substantially trapezoidal extension portion 12b extending from the vicinity of the upper end of the end toward the A direction to a position corresponding to the approximate center of the connecting portion 20a in the x direction. The upper end of the extended portion 12b is on the same plane as the upper end of the side wall body 12a, and the lower end of the extended portion 12b is inclined upward as it goes downstream in the A direction. As viewed from the y direction, the male contact insertion port side end (right side in FIG. 2) of the side wall main body 12a and the downstream end in the A direction of the extended portion 12b are both perpendicular to the bottom wall 11. Further, a contact portion 12x that protrudes inward, which will be described in detail later, is formed at the approximate center in the x direction near the upper end of the side wall body 12a.

ここで図３及び図４を参照しつつ、Ａ方向から見た側壁１２各部の形状について述べる。これらの図から、底壁１１のｙ方向長さに比べて側壁１２のｚ方向長さが大きく、ソケット１０が横断面視においてｚ方向に細長であること、両側壁１２はソケット１０のｘ方向中心軸に関して対称形状であることなどがわかる。   Here, the shape of each part of the side wall 12 viewed from the A direction will be described with reference to FIGS. 3 and 4. From these figures, the z-direction length of the side wall 12 is larger than the y-direction length of the bottom wall 11, the socket 10 is elongated in the z-direction in a cross-sectional view, and both side walls 12 are in the x-direction of the socket 10. It can be seen that the shape is symmetrical about the central axis.

各側壁本体１２ａは底壁１１との接続部より若干上方において内側に屈曲し、ｘ方向に沿った屈曲線（図２参照）が形成されている。そしてこれより上方は、上端に近づくほど互いのｙ方向に関する間隔が小さくなるよう、内側に傾斜している。換言すると、両側壁本体１２ａにおける上記屈曲線の上方は、横断面視でハの字状となっている。両側壁本体１２ａのｙ方向に関する外側面間隔は、底壁１１との接続部近傍において最も大きく、これをＤｏ１とする。Ｄｏ１は底壁１１の幅とほぼ等しい。   Each side wall body 12a bends inward slightly above the connection with the bottom wall 11, and a bend line (see FIG. 2) along the x direction is formed. And the upper part is inclined inward so that the interval in the y direction becomes smaller toward the upper end. In other words, the upper side of the bent line in the both side wall main body 12a has a square shape in a cross sectional view. The outer surface spacing in the y direction of both side wall main bodies 12a is the largest in the vicinity of the connecting portion with the bottom wall 11, and this is Do1. Do1 is approximately equal to the width of the bottom wall 11.

両側壁本体１２ａのｙ方向に関する内側面間隔は、接触部１２ｘにおいて最も小さくなっており、これをＤｉ３とする。Ｄｉ３は雄コンタクト１００のｙ方向長さ（即ち幅Ｗ、図１参照）より小さいので、接触部１２ｘは後に詳述するように弾性力を付与しつつ雄コンタクト１００と接触可能であって、これにより雄コンタクト１００を所定の接触圧にて導通可能に保持することができる。   The distance between the inner side surfaces of the side wall bodies 12a in the y direction is the smallest at the contact portion 12x, and this is Di3. Since Di3 is smaller than the length of the male contact 100 in the y direction (ie, width W, see FIG. 1), the contact portion 12x can contact the male contact 100 while applying an elastic force, as will be described in detail later. Thus, the male contact 100 can be held conductive at a predetermined contact pressure.

拡張部１２ｂは底壁１１に対してほぼ垂直であり、両拡張部１２ｂのｙ方向に関する内側面間隔はＤｉ３より大きい。そのため、後述のように雄コンタクト１００を当該雌コンタクト１のソケット１０内に収容した時、拡張部１２ｂは雄コンタクト１００から離隔する。両拡張部１２ｂのｙ方向に関する外側面間隔をＤｏ２とする。   The extended portion 12b is substantially perpendicular to the bottom wall 11, and the distance between the inner surfaces of both the extended portions 12b in the y direction is larger than Di3. Therefore, when the male contact 100 is accommodated in the socket 10 of the female contact 1 as will be described later, the expansion portion 12 b is separated from the male contact 100. The distance between the outer surfaces in the y direction of both the extended portions 12b is Do2.

上方から見ると（図１参照）、側壁１２の上端が曲線を描いているのがわかる。より詳細には、両側壁１２の上端は、接触部１２ｘより雄コンタクト挿入口側に近づくにつれて、また接触部１２ｘから拡張部１２ｂのＡ方向末端に近づくにつれて、ｙ方向の内外両側面間隔が大きくなっている。特に側壁１２の雄コンタクト挿入口側の上端部近傍は、壁厚が小さくなるように面取り加工されている。   When viewed from above (see FIG. 1), it can be seen that the upper end of the side wall 12 is curved. More specifically, the distance between the inner and outer side surfaces in the y direction increases as the upper ends of the side walls 12 approach the male contact insertion port side from the contact portion 12x and approach the end in the A direction of the extension portion 12b from the contact portion 12x. It has become. In particular, the vicinity of the upper end of the side wall 12 on the male contact insertion port side is chamfered so that the wall thickness is reduced.

導体圧着部２０及び絶縁体圧着部３０は、図１〜図３に示すように、いずれも上方が開放されたＵ字型に形成されている。導体圧着部２０及び絶縁体圧着部３０は、雌コンタクト１の使用時には、図５（Ａ）及び図６に示すように、電線５０の導体５１及び絶縁体外皮５２をそれぞれ圧着固定する。   As shown in FIGS. 1 to 3, the conductor crimping portion 20 and the insulator crimping portion 30 are each formed in a U-shape with the top opened. When the female contact 1 is used, the conductor crimping portion 20 and the insulator crimping portion 30 crimp and fix the conductor 51 and the insulator outer sheath 52 of the electric wire 50, respectively, as shown in FIGS.

次に、図５（Ａ），（Ｂ）及び図６を参照しつつ、雌コンタクト１がハウジング４０内に格納された状態、及び、雌コンタクト１内に雄コンタクト１００が収容された状態について説明する。本実施形態において、ハウジング４０は３つの雌コンタクト１を格納する。そこで図５（Ａ）及び図６では３つの雌コンタクト１のうち紙面奥側の雌コンタクト１のみに符番を付し、その他紙面手前側の２つの雌コンタクト１についてはこれと同様として符番を省略する。   Next, a state in which the female contact 1 is stored in the housing 40 and a state in which the male contact 100 is accommodated in the female contact 1 will be described with reference to FIGS. To do. In the present embodiment, the housing 40 stores three female contacts 1. Therefore, in FIGS. 5A and 6, only the female contact 1 on the back side of the sheet of the three female contacts 1 is numbered, and the other two female contacts 1 on the front side of the sheet are numbered similarly. Is omitted.

先ず、ハウジング４０の構成について説明する。図５（Ａ）に示すように、ハウジング４０は、雌コンタクト１を格納するための略直方体状の雌コンタクト格納室４１を３つ有している。各雌コンタクト格納室４１は、ｘ方向に延在し、図５（Ａ）の左側にあるハウジング４０のｘ方向一端に開口している。この開口から、ソケット１０を先端として雌コンタクト１を挿入可能であると共に、雌コンタクト１が格納されたときには導体圧着部２０及び絶縁体圧着部３０で圧着固定された導線５０が外部に引き出される。この開口のハウジング４０端面近傍は、その周縁が切り欠かれることにより、開口面積が大きくなっている。   First, the configuration of the housing 40 will be described. As shown in FIG. 5A, the housing 40 has three female contact storage chambers 41 each having a substantially rectangular parallelepiped shape for storing the female contacts 1. Each female contact storage chamber 41 extends in the x direction and opens at one end in the x direction of the housing 40 on the left side of FIG. From this opening, the female contact 1 can be inserted with the socket 10 as the tip, and when the female contact 1 is stored, the lead wire 50 crimped and fixed by the conductor crimping portion 20 and the insulator crimping portion 30 is drawn out. In the vicinity of the end face of the housing 40 of the opening, the opening area is increased by cutting out the peripheral edge.

一方、図５（Ａ）の右側にあるハウジング４０のｘ方向他端には、各雌コンタクト格納室４１に連通するように、雄コンタクト挿入口４５が３つ形成されている。雄コンタクト挿入口４５は、雄コンタクト１００（図６参照）を挿抜可能なように雄コンタクト１００の横断面より若干大きな相似形状を有すると共に、上記開口と同様にそのハウジング４０端面近傍は切り欠かれて開口面積が大きくなっている。   On the other hand, three male contact insertion ports 45 are formed at the other end in the x direction of the housing 40 on the right side of FIG. 5A so as to communicate with each female contact storage chamber 41. The male contact insertion opening 45 has a similar shape slightly larger than the cross section of the male contact 100 so that the male contact 100 (see FIG. 6) can be inserted and removed, and the vicinity of the end face of the housing 40 is cut out in the same manner as the opening. The opening area is large.

各雌コンタクト格納室４１は、ソケット１０を保持する部分において、図５（Ｂ）に示すような横断面形状を有する。より詳細には、雌コンタクト格納室４１は、下部に形成された幅広空間４１ａと上部に形成された幅狭空間４１ｂとを有する。幅広空間４１ａ及び幅狭空間４１ｂの幅（即ちｙ方向の長さ）は、それぞれＤｏ１（両側壁本体１２ａの底壁１１との接続部近傍におけるｙ方向に関する外側面間隔）及びＤｏ２（両拡張部１２ｂのｙ方向に関する外側面間隔）にほぼ等しい。このような幅の異なる空間４１ａ，４１ｂにより、ハウジング４０には段差が形成されている。幅広空間４１ａ及び幅狭空間４１ｂの高さ（即ちｚ方向の長さ）はほぼ同じであり、両方でソケット１０の高さより若干大きくなっている。   Each female contact storage chamber 41 has a cross-sectional shape as shown in FIG. More specifically, the female contact storage chamber 41 has a wide space 41a formed in the lower portion and a narrow space 41b formed in the upper portion. The widths of the wide space 41a and the narrow space 41b (that is, the length in the y direction) are Do1 (interval between outer surfaces in the y direction in the vicinity of the connecting portion with the bottom wall 11 of both side wall bodies 12a) and Do2 (both extended portions) 12b is substantially equal to the outer surface interval in the y direction). A step is formed in the housing 40 by the spaces 41a and 41b having different widths. The widths of the wide space 41a and the narrow space 41b (that is, the length in the z direction) are substantially the same, and both are slightly larger than the height of the socket 10.

雌コンタクト１が格納室４１に格納された状態において、ソケット１０の底壁１１は幅広空間４１ａの下部に位置するハウジング４０内壁に支持され、側壁本体１２ａにおける底壁１１との接続部近傍は幅広空間４１ａ両側のハウジング４０内壁とほぼ接触している。これにより、ソケット１０の下部は雌コンタクト格納室４１内に安定して保持される。一方、ソケット１０の上部については、拡張部１２ｂが幅狭空間４１ｂ両側のハウジング４０内壁にほぼ接触することになる。   In a state where the female contact 1 is stored in the storage chamber 41, the bottom wall 11 of the socket 10 is supported by the inner wall of the housing 40 positioned at the lower part of the wide space 41a, and the vicinity of the connection portion with the bottom wall 11 in the side wall body 12a is wide. It is substantially in contact with the inner walls of the housing 40 on both sides of the space 41a. Thereby, the lower part of the socket 10 is stably held in the female contact storage chamber 41. On the other hand, about the upper part of the socket 10, the expansion part 12b substantially contacts the inner wall of the housing 40 on both sides of the narrow space 41b.

雌コンタクト１と電気的に接触させる雄コンタクト１００は、図６に示すように、予めハウジング１４０に係止されている。そしてハウジング４０，１４０同士を係合させる作業に伴って、両コンタクト１，１００間の電気的接触が実現される。より詳細には、雄コンタクト用ハウジング１４０が雌コンタクト用ハウジング４０を覆うようにこれと係合するのに伴って、各雄コンタクト１００はハウジング４０の雄コンタクト挿入口４５、雌コンタクト１のソケット１０における側壁本体１２ａの間を順次通過し、さらに接触部１２ｘと接触してこれを外側に押し広げつつ挿入され、ハウジング４０，１４０同士の係合が完了する。このとき雄コンタクト１００は、接触部１２ｘが付与する弾性力によってソケット１０内において確実に固定され、所定の接触圧にて導通可能に保持される。これにより、両コンタクト１、１００間の良好な電気的接触が保たれる。一方、拡張部１２ｂはこのとき雄コンタクト１００と接触することなく離隔している。   As shown in FIG. 6, the male contact 100 that makes electrical contact with the female contact 1 is locked to the housing 140 in advance. And the electrical contact between both the contacts 1 and 100 is implement | achieved with the operation | work which engages housings 40 and 140 with each other. More specifically, as the male contact housing 140 is engaged with the female contact housing 40 so as to cover it, each male contact 100 is connected to the male contact insertion slot 45 of the housing 40 and the socket 10 of the female contact 1. Are sequentially passed between the side wall main bodies 12a, and further inserted into the contact portion 12x in contact with the contact portion 12x, spreading the outside outward, thereby completing the engagement between the housings 40 and 140. At this time, the male contact 100 is securely fixed in the socket 10 by the elastic force applied by the contact portion 12x, and held so as to be conductive at a predetermined contact pressure. Thereby, the favorable electrical contact between both the contacts 1 and 100 is maintained. On the other hand, the extended part 12b is separated without contacting the male contact 100 at this time.

以上に述べたように、本実施形態の雌コンタクト１によると、雌コンタクト１がハウジング４０内に格納されると、図５（Ｂ）に示すように、ソケット１０の底壁１１及び側壁本体１２ａの底壁１１との接続部近傍に加え、拡張部１２ｂもハウジング４０とほぼ接触する。このようにソケット１０がその上部及び下部両方においてハウジング４０とほぼ接触する場合、図６のようにソケット１０の収容空間内に収容された雄コンタクト１００、または雌コンタクト１に接続された電線５０に外力がかかり、雌コンタクト１にその横断面方向の力が加わっても、雌コンタクト１のハウジング４０内での横転が防止される。つまり本実施形態の構成によると、雌コンタクト１をハウジング４０内にて安定して保持することができる。   As described above, according to the female contact 1 of the present embodiment, when the female contact 1 is stored in the housing 40, the bottom wall 11 and the side wall body 12a of the socket 10 as shown in FIG. In addition to the vicinity of the connecting portion with the bottom wall 11, the extended portion 12 b also substantially contacts the housing 40. Thus, when the socket 10 substantially contacts the housing 40 in both the upper part and the lower part, the male contact 100 accommodated in the accommodating space of the socket 10 or the electric wire 50 connected to the female contact 1 as shown in FIG. Even if an external force is applied and a force in the cross-sectional direction is applied to the female contact 1, the female contact 1 is prevented from rolling over in the housing 40. That is, according to the configuration of the present embodiment, the female contact 1 can be stably held in the housing 40.

また本実施形態の拡張部１２ｂは、図１及び図２に示すように、側壁１２のｘ向末端に設けられている。この構成によると、側壁１２に拡張部１２ｂを形成するにあたり、そのｘ方向末端を適宜の器具で外側に押し広げるなどすればよく、拡張部１２ｂを比較的簡単に形成することができる。   Further, the extension portion 12b of the present embodiment is provided at the end of the side wall 12 in the x direction as shown in FIGS. According to this configuration, in forming the extension portion 12b on the side wall 12, the extension portion 12b can be formed relatively easily by pushing the x-direction end outward with an appropriate tool.

側壁１２に形成された接触部１２ｘ及び拡張部１２ｂはＡ方向に沿って順に設けられている。また側壁１２の雄コンタクト挿入口側の上端部近傍が面取り加工されていることにより、図１に示すように、側壁１２の上端におけるｙ方向に関する互いの内側面間隔が接触部１２ｘよりも雄コンタクト挿入口において大きい。したがって、雄コンタクト１００をソケット１０内に挿入するときその先端が側壁に当接するのが防止され、雄コンタクト１００の挿入作業を円滑に行うことができる。つまり、雄コンタクト挿入口では側壁１２の内側面間隔を雄コンタクト１００の幅Ｗより大きくすることによって雄コンタクト１００を挿入しやすくすると共に、これよりＡ方向下流側にある接触部１２ｘでは側壁１２の内側面間隔を小さくすることで、雄コンタクト１００に弾性力を付与しつつこれを挟持し、雄コンタクト１００との接続信頼性を高めることができる。   The contact portion 12x and the extended portion 12b formed on the side wall 12 are provided in order along the A direction. Further, since the vicinity of the upper end portion of the side wall 12 on the male contact insertion port side is chamfered, as shown in FIG. 1, the distance between the inner side surfaces in the y direction at the upper end of the side wall 12 is greater than that of the contact portion 12x. Big in the insertion slot. Therefore, when the male contact 100 is inserted into the socket 10, the tip thereof is prevented from coming into contact with the side wall, and the male contact 100 can be inserted smoothly. That is, in the male contact insertion opening, the inner surface interval of the side wall 12 is made larger than the width W of the male contact 100 so that the male contact 100 can be easily inserted. By reducing the interval between the inner side surfaces, the male contact 100 can be clamped while applying an elastic force, and the connection reliability with the male contact 100 can be improved.

また図３及び図４に示すように、ソケット１０は横断面視においてｚ方向に細長である。つまり、ソケット１０における側壁１２のｙ方向に沿った長さが比較的小さいので、省スペース化に有効である。さらにこの構成のようにソケット１０の横断面が細長である場合、ハウジング４０内での雌コンタクト１の安定性が確保されにくく、上述のような横転の問題が顕著になるが、本実施形態ではこのような場合でも雌コンタクト１の横断面方向への横転を防止し、これを安定して保持することができる。   As shown in FIGS. 3 and 4, the socket 10 is elongated in the z direction in a cross-sectional view. That is, since the length along the y direction of the side wall 12 in the socket 10 is relatively small, it is effective for space saving. Further, when the cross section of the socket 10 is elongated like this configuration, it is difficult to ensure the stability of the female contact 1 in the housing 40, and the problem of rollover as described above becomes significant. Even in such a case, the female contact 1 can be prevented from rolling over in the cross-sectional direction and can be stably held.

以上、本発明の好適な一実施の形態について説明したが、本発明は上述の実施の形態に限られるものではなく、特許請求の範囲に記載した限りにおいて、様々な設計変更を行うことが可能なものである。特に、以下のような変更が考えられる。   The preferred embodiment of the present invention has been described above. However, the present invention is not limited to the above-described embodiment, and various design changes can be made as long as they are described in the claims. It is a thing. In particular, the following changes can be considered.

ソケット１０は横断面視においてｚ方向に細長でなくてよい。   The socket 10 does not have to be elongated in the z direction in a cross-sectional view.

また、拡張部１２ｂは側壁１２のｘ向末端に設けられなくてもよいし、接触部１２ｘ及び拡張部１２ｂはＡ方向に沿って順に設けられなくてもよい。つまり、拡張部１２ｂは側壁１２の上端近傍にあればよく、拡張部１２ｂのｘ方向に関する位置は特に限定されない。例えば雄コンタクト挿入口近傍において側壁１２をｙ方向外側に広げることで拡張部１２ｂを形成してもよいし、接触部１２ｘを側壁のｚ方向中央近傍に設けてその上端近傍をｙ方向外側に広げることで拡張部１２ｂを形成してもよい。   Moreover, the extended part 12b does not need to be provided in the x direction terminal of the side wall 12, and the contact part 12x and the extended part 12b do not need to be provided in order along the A direction. That is, the extended portion 12b only needs to be near the upper end of the side wall 12, and the position of the extended portion 12b in the x direction is not particularly limited. For example, the extended portion 12b may be formed by expanding the side wall 12 in the vicinity of the male contact insertion opening in the y direction, or the contact portion 12x may be provided in the vicinity of the center of the side wall in the z direction and the vicinity of the upper end may be expanded outward in the y direction. Thus, the extended portion 12b may be formed.

上述の実施の形態では、雄コンタクト１００の挿入作業を円滑に行えるように、側壁１２の上端におけるｙ方向に関する互いの内側面間隔が接触部１２ｘよりも雄コンタクト挿入口において大きいが、これに限定されず、雄コンタクト挿入口における上記内側面間隔が雄コンタクト１００の幅Ｗとほぼ同一であってもよい。   In the above-described embodiment, the inner surface spacing in the y direction at the upper end of the side wall 12 is larger at the male contact insertion port than at the contact portion 12x so that the male contact 100 can be inserted smoothly. Instead, the inner surface spacing at the male contact insertion opening may be substantially the same as the width W of the male contact 100.

雄コンタクト１００の形状は板状に限定されず、ピン状であってもよい。そして雄コンタクト１００の形状に応じ、本発明の主旨を逸脱しない範囲で、雌コンタクト１の形状、特にソケット１０の形状を適宜変更してよい。   The shape of the male contact 100 is not limited to a plate shape, and may be a pin shape. Depending on the shape of the male contact 100, the shape of the female contact 1, especially the shape of the socket 10, may be changed as appropriate without departing from the spirit of the present invention.

雌コンタクト１の各部は１枚の平板から形成されると説明したが、これに限定されず、例えばランス１１ａを別部材としてもよい。また、雌コンタクト１の各部は同一の材料からなることに限定されず、異なる材料からなってもよい。   Although it has been described that each part of the female contact 1 is formed of a single flat plate, the present invention is not limited to this, and the lance 11a may be a separate member, for example. Moreover, each part of the female contact 1 is not limited to being made of the same material, and may be made of different materials.
