Description

本発明は、回路基板用電気コネクタに関する。   The present invention relates to an electrical connector for a circuit board.

回路基板上に配され、ハウジングの対を成す二つの側壁で複数の端子が配列保持される回路基板用電気コネクタとして、例えば、特許文献１のコネクタが知られている。この特許文献１のコネクタは、周壁によって囲まれた受入空間に相手コネクタを上方から受入可能な略直方体外形のハウジングと、該ハウジングの周壁のうち互いに対向してハウジング長手方向に延びる二つの側壁で配列保持される複数の端子とを有している。   For example, a connector disclosed in Patent Document 1 is known as an electrical connector for a circuit board that is arranged on a circuit board and has a plurality of terminals arranged and held by two side walls forming a pair of housings. The connector disclosed in Patent Document 1 includes a substantially rectangular parallelepiped housing capable of receiving a mating connector from above in a receiving space surrounded by a peripheral wall, and two side walls extending in the longitudinal direction of the housing so as to face each other. And a plurality of terminals held in an array.

この特許文献１のコネクタは、端子は逆Ｕ状部を有していて、該逆Ｕ字状部がハウジングの側壁へ下方から圧入されあるいは該側壁と一体成形されて保持されている。該逆Ｕ字状部の二つの脚部は、二つの側壁の対向方向（コネクタ幅方向）で所定の間隔をもって互いに平行をなし上下方向で真っ直ぐに延びている。上記対向方向にて外側に位置する外側脚部はその下端で屈曲されていて、回路基板上の対応回路部に半田接続可能な接続部が上記対向方向外側へ向けてハウジング外へ延びている。   In the connector of Patent Document 1, the terminal has an inverted U-shaped portion, and the inverted U-shaped portion is press-fitted into the side wall of the housing from below or is integrally formed with the side wall and held. The two leg portions of the inverted U-shaped portion are parallel to each other at a predetermined interval in the opposing direction of the two side walls (connector width direction) and extend straight in the vertical direction. The outer leg portion located outside in the facing direction is bent at the lower end thereof, and a connecting portion capable of being soldered to the corresponding circuit portion on the circuit board extends out of the housing toward the outside in the facing direction.

特開２００２−０３３１４５JP2002-033145

通常、回路基板用コネクタは、低背化すなわち回路基板の面に対して直角な方向での寸法が小さいことが要請されるが、これとともに、回路基板上で他の電子部品を設置するためのスペースを確保するという要請から、回路基板に平行な方向でも小型化されていることが好ましい。上述した特許文献１のコネクタは、端子の接続部が、外側脚部の下端から側壁の対向方向外側へ延出してハウジング外に位置しているので、延出分だけ上記対向方向での寸法が大きくなっており、この点で、該対向方向でのコネクタの小型化について改善の余地がある。しかし、仮に、上記接続部を単純に短くしてコネクタの小型化を図ろうとすると、該接続部での半田接続できる部分の面積が小さくなってしまい、コネクタと回路基板との電気的な導通が不安定になるとともに、回路基板へのコネクタの固定強度が低下するおそれがある。   Usually, a circuit board connector is required to have a low profile, that is, a small size in a direction perpendicular to the surface of the circuit board. At the same time, it is necessary to install other electronic components on the circuit board. In order to secure a space, it is preferable that the size is reduced even in a direction parallel to the circuit board. In the connector of Patent Document 1 described above, the terminal connection portion extends from the lower end of the outer leg portion to the outside in the opposite direction of the side wall and is positioned outside the housing. In this respect, there is room for improvement in terms of downsizing the connector in the opposite direction. However, if it is attempted to reduce the size of the connector by simply shortening the connecting portion, the area of the connecting portion that can be soldered is reduced, and the electrical connection between the connector and the circuit board is reduced. In addition to being unstable, the strength of fixing the connector to the circuit board may be reduced.

このような事情に鑑みて、本発明は、接続部を短くすることなく、ハウジングの側壁の対向方向でコネクタを小型化できる回路基板用コネクタを提供することを目的とする。   In view of such circumstances, an object of the present invention is to provide a circuit board connector capable of reducing the size of the connector in the facing direction of the side wall of the housing without shortening the connecting portion.

本発明に係る回路基板用電気コネクタは、回路基板上に配され上方から相手コネクタを受け入れて該相手コネクタと嵌合接続される電気コネクタであって、上下方向に起立し互いに対向して回路基板の面と平行に延びる二つの側壁を有するハウジングと、上記二つの側壁のうち少なくとも一方の側壁に配列保持された複数の端子とを備え、上記ハウジングは、上記二つの側壁の互いに対向する内側面同士間に、上記相手コネクタを受け入れるための受入空間が形成されており、上記端子は、上記側壁に保持されており、側壁同士の対向方向にて受入空間側の位置で上下方向に延びる内側脚部と、上記対向方向にて上記内側脚部よりも外側位置で上下方向に延びる外側脚部と、上記内側脚部および外側脚部の上端同士を連結する連結部と、上記外側脚部の下端から上記対向方向外側に向け延び回路基板上の対応回路部に半田接続される接続部とを有している。   An electrical connector for a circuit board according to the present invention is an electrical connector that is disposed on a circuit board, receives the mating connector from above, and is fitted and connected to the mating connector. The circuit board stands up and down and faces each other. And a plurality of terminals arranged and held on at least one of the two side walls, wherein the housing is an inner surface of the two side walls facing each other. A receiving space for receiving the mating connector is formed between them, the terminal is held by the side wall, and an inner leg that extends in the vertical direction at a position on the receiving space side in a facing direction of the side walls. A connecting portion that connects upper ends of the inner leg portion and the outer leg portion, and an outer leg portion that extends in the up-down direction at a position outside the inner leg portion in the opposing direction; From the lower end of the side leg portions and a connecting portion which is connected by soldering to a corresponding circuit portion of the circuit board extends toward the opposite direction outside.

かかる回路基板用電気コネクタにおいて、本発明では、上記外側脚部は、該外側脚部の下端が上端よりも上記対向方向で内側に位置しており、上記接続部は、少なくとも一部が上記対向方向で外側脚部と重複する範囲内に位置していることを特徴としている。   In such an electrical connector for a circuit board, in the present invention, the outer leg has the lower end of the outer leg positioned on the inner side in the opposing direction with respect to the upper end, and at least a part of the connecting part is opposed to the upper end. It is located in the range which overlaps with an outer leg part in the direction.

本発明では、端子の外側脚部は、該外側脚部の下端が上端よりも二つの側壁の対向方向で内側に位置しており、かつ、接続部が、該外側脚部の下端から上記対向方向外側へ向けて延びており、接続部の少なくとも一部が外側脚部の下方にて、上記対向方向で外側脚部と重複して位置している。したがって、従来のような、外側脚部が内側脚部と平行に上下方向で真っ直ぐに延び、該外側脚部の下端から接続部がハウジング外へ延出している場合と比較して、本発明では、接続部が、上記対向方向で外側脚部と重複して位置している分だけ、上記対向方向で内側に寄って位置することとなる。この結果、接続部の長さを変えなくても、該接続部は、ハウジング外に位置する部分の長さが短くなるので、上記対向方向でコネクタが小さくなる。また、接続部自体の長さは短くならないので、コネクタと回路基板との電気的な導通が不安定にならず、回路基板へのコネクタの固定強度が低下することもない。   In the present invention, the outer leg portion of the terminal has the lower end of the outer leg portion positioned on the inner side in the opposing direction of the two side walls with respect to the upper end, and the connecting portion is opposed to the lower end of the outer leg portion. It extends toward the outer side in the direction, and at least a part of the connecting portion is located below the outer leg portion and overlaps with the outer leg portion in the facing direction. Therefore, compared with the conventional case where the outer leg portion extends straight in the vertical direction parallel to the inner leg portion, and the connection portion extends out of the housing from the lower end of the outer leg portion, The connecting portion is located closer to the inside in the facing direction by the amount that overlaps with the outer leg portion in the facing direction. As a result, even if the length of the connecting portion is not changed, the length of the portion of the connecting portion located outside the housing is shortened, so that the connector becomes small in the facing direction. Further, since the length of the connection portion itself is not shortened, the electrical continuity between the connector and the circuit board does not become unstable, and the fixing strength of the connector to the circuit board does not decrease.

本発明において、外側脚部は、側壁の対向方向にて、下端の少なくとも一部が内側脚部と重複して位置していることが好ましい。このように外側脚部の下端の少なくとも一部が側壁の対向方向で内側脚部と重複させることにより、その重複した分だけ、端子の接続部を、さらに上記対向方向で内側に位置させることができ、接続部のハウジング外方へ延出する部分の長さを短くできる。したがって、上記対向方向でコネクタをさらに小さくできる。   In the present invention, it is preferable that at least a part of the lower end of the outer leg portion overlaps with the inner leg portion in the opposite direction of the side wall. Thus, by making at least a part of the lower end of the outer leg part overlap with the inner leg part in the opposing direction of the side wall, the terminal connection part can be positioned further inward in the opposing direction by the overlap. And the length of the portion of the connecting portion extending outward from the housing can be shortened. Therefore, the connector can be further reduced in the facing direction.

本発明において、外側脚部は、上端から下端に向け内側脚部に近づくように傾斜または屈曲していることが好ましい。   In the present invention, the outer leg is preferably inclined or bent so as to approach the inner leg from the upper end toward the lower end.

本発明において、内側脚部は、受入空間内に向けて露呈して上端寄り位置で相手コネクタの端子と接触可能に位置していることとしてもよい。内側脚部が上端寄り位置で相手コネクタの端子（相手端子）と接触可能となっている場合、コネクタ同士を嵌合する際、該内側脚部および側壁は、相手端子や該相手端子を保持するハウジングから側壁の対向方向で外側へ向けた押圧力を受け、上記側壁が下部を支点として外側へ撓む。従来のように、内側脚部と外側脚部とが上下方向全域にわたって所定の間隔をもって平行に真っ直ぐ延びている場合、両脚部の下端同士においても上端と同じく上記所定の間隔が形成されており、該間隔によって外側脚部が上記押圧力に対して抗する対抗モーメントを生じるように作用するので、側壁は外側へ撓みにくい。したがって、相手コネクタの端子との接触時にて内側脚部も撓みにくいので、相手コネクタの挿入に必要な挿入力が大きくなってしまう。   In the present invention, the inner leg portion may be exposed to the inside of the receiving space and positioned so as to be in contact with the terminal of the mating connector at a position near the upper end. When the inner leg is in contact with the terminal of the mating connector (mating terminal) near the upper end, the inner leg and the side wall hold the mating terminal and the mating terminal when the connectors are fitted together. Upon receiving a pressing force directed outward from the housing in the opposite direction of the side wall, the side wall bends outward with the lower part as a fulcrum. As in the prior art, when the inner leg portion and the outer leg portion extend straight in parallel at a predetermined interval across the entire vertical direction, the predetermined interval is formed at the lower ends of both leg portions in the same manner as the upper ends. Since the outer legs act so as to generate a counter-moment against the pressing force by the distance, the side wall is not easily bent outward. Therefore, the inner leg portion is also difficult to bend when contacting the terminal of the mating connector, and the insertion force required for inserting the mating connector is increased.

一方、本発明では、外側脚部の下端が上端よりも上記対向方向で内側、すなわち内側脚部寄りに位置していて、下端同士の間隔が生じないあるいは小さいので、外側脚部が生じる対抗モーメントが作用しにくい。したがって、側壁そして内側脚部は下部を支点として外側へ撓みやすいので、コネクタ嵌合時において相手コネクタの挿入に必要な挿入力を小さくすることができる。   On the other hand, in the present invention, the lower end of the outer leg is located in the opposite direction from the upper end, that is, closer to the inner leg, and the distance between the lower ends does not occur or is small. Is hard to act. Therefore, since the side wall and the inner leg portion are easily bent outward with the lower portion as a fulcrum, the insertion force required for inserting the mating connector can be reduced when the connector is fitted.

本発明において、端子は、ハウジングとの一体成形で被保持部が該ハウジングにより保持されてもよい。また、端子は、被保持部が内側脚部、外側脚部および連結脚部の少なくとも一つに形成され、該被保持部にて側壁へ圧入保持されてもよい。   In the present invention, the held portion may be held by the housing by integral molding with the housing. The terminal may be formed such that the held portion is formed on at least one of the inner leg portion, the outer leg portion, and the connecting leg portion, and press-fitted and held on the side wall by the held portion.

以上のように、本発明では、端子の外側脚部が、該外側脚部の下端が上端よりも側壁の対向方向で内側に位置しているので、接続部の少なくとも一部が外側脚部の下方位置にて上記対向方向で該外側脚部と重複する分だけ、該接続部を該対向方向で内側に位置させることができる。したがって、接続部の長さを変えなくても、該接続部のハウジング外に位置する部分の長さを短くでき、該対向方向でコネクタを小型化することができる。また、接続部自体の長さを短くしないで済むので、コネクタと回路基板との電気的な導通が不安定なることそして回路基板へのコネクタの固定強度が低下することを回避できる。   As described above, in the present invention, since the outer leg portion of the terminal is located on the inner side in the opposing direction of the side wall with respect to the upper end, the lower end of the outer leg portion is at least part of the outer leg portion. The connecting portion can be positioned inward in the facing direction by an amount overlapping the outer leg in the facing direction at the lower position. Therefore, even without changing the length of the connecting portion, the length of the portion of the connecting portion located outside the housing can be shortened, and the connector can be miniaturized in the facing direction. In addition, since it is not necessary to shorten the length of the connection portion itself, it is possible to avoid unstable electrical conduction between the connector and the circuit board and a decrease in the strength of fixing the connector to the circuit board.

以下、添付図面に基づいて本発明に係る回路基板用電気コネクタの実施形態を説明する。   Embodiments of an electrical connector for a circuit board according to the present invention will be described below with reference to the accompanying drawings.

＜第一実施形態＞
［コネクタの構成］
図１は、本実施形態に係るコネクタ１の斜視図であり、ハウジング長手方向における端子２０の位置での断面を示している。また、図２は、本実施形態に係るコネクタ１および相手コネクタ２のハウジング長手方向における端子２０の位置での断面図であり、コネクタ嵌合前の状態を示している。 <First embodiment>
[Connector configuration]
FIG. 1 is a perspective view of the connector 1 according to the present embodiment, and shows a cross section at the position of the terminal 20 in the longitudinal direction of the housing. FIG. 2 is a cross-sectional view of the connector 1 and the mating connector 2 according to this embodiment at the position of the terminal 20 in the housing longitudinal direction, and shows a state before the connector is fitted.

本実施形態に係るコネクタ１は、回路基板（図示せず）上に配され上方から相手コネクタ２を受け入れて該相手コネクタ２と嵌合接続される電気コネクタであり、略直方体外形をなす合成樹脂製のハウジング１０と、該ハウジング１０の長手方向で該ハウジング１０に配列保持される複数の金属製の端子２０と、該ハウジング１０の長手方向、すなわち端子配列方向で端子２０の配列範囲に対して両方の外側位置で該ハウジング１０に保持される固定金具３０とを有している。   A connector 1 according to this embodiment is an electrical connector that is arranged on a circuit board (not shown), receives the mating connector 2 from above, and is fitted and connected to the mating connector 2, and is a synthetic resin having a substantially rectangular parallelepiped outer shape. Housing 10, a plurality of metal terminals 20 arranged and held in the housing 10 in the longitudinal direction of the housing 10, and the longitudinal direction of the housing 10, that is, in the terminal arrangement direction with respect to the arrangement range of the terminals 20 It has a fixture 30 held by the housing 10 at both outer positions.

図１および図２に示されているように、上記ハウジング１０は、回路基板（図示せず）の面に対面し端子配列方向を長手方向として延びる底壁１１と、後述の二つの側壁１３の間で該長手方向に延びるとともに該底壁１１から上方へ向け突出する突壁部１２と、該底壁１１から上方に起立し該突壁部１２を囲む周壁とを有している。該周壁は、互いに対向して上記長手方向に延びる二つの側壁１３と、該二つの側壁１３の端部同士を連結し該長手方向に対して直角な短手方向に延びる二つの端壁１４とを有している。上記周壁と突壁部１２との間で上方に開口した四角環状の空間は、相手コネクタ２の嵌合部を受け入れるための受入凹部１５として形成されている。   As shown in FIGS. 1 and 2, the housing 10 has a bottom wall 11 facing a surface of a circuit board (not shown) and extending in the terminal arrangement direction as a longitudinal direction, and two side walls 13 described later. A protruding wall portion 12 extending in the longitudinal direction and projecting upward from the bottom wall 11, and a peripheral wall standing upward from the bottom wall 11 and surrounding the protruding wall portion 12. The peripheral wall includes two side walls 13 that extend in the longitudinal direction so as to face each other, and two end walls 14 that connect ends of the two side walls 13 and extend in a short direction perpendicular to the longitudinal direction. have. A square annular space opened upward between the peripheral wall and the projecting wall portion 12 is formed as a receiving recess 15 for receiving the fitting portion of the mating connector 2.

上記突壁部１２は、上記長手方向にて隣接する端子２０同士間に対応する位置で規制突部１２Ａを有している。該規制突部１２Ａは、上記側壁１３の内側面と対面する突壁部１２の側面から上記短手方向に突出し上下方向に延びている。該規制突部１２Ａは、コネクタ嵌合過程そしてコネクタ嵌合状態にて、その突出頂部が、ハウジング１０の短手方向で、相手コネクタ２の嵌合部と当接することにより、該短手方向での該相手コネクタ２の位置を規制するようになっている。その結果、後述する端子２０の弾性腕部２２が相手端子５０に過度に押圧されて変位することに起因して該弾性腕部が損傷する、いわゆる「へたり」を防止することができる。   The protruding wall portion 12 has a restriction protruding portion 12A at a position corresponding to between the terminals 20 adjacent in the longitudinal direction. The restricting protrusion 12A protrudes from the side surface of the protruding wall portion 12 facing the inner surface of the side wall 13 in the short direction and extends in the vertical direction. In the connector fitting process and in the connector fitting state, the restricting protrusion 12A has a protruding top portion in the short direction of the housing 10 and abuts the fitting portion of the mating connector 2 in the short direction. The position of the mating connector 2 is regulated. As a result, it is possible to prevent so-called “sagging” in which the elastic arm portion 22 of the terminal 20 described later is damaged by being excessively pressed and displaced by the mating terminal 50.

上記突壁部１２は、隣接する規制突部１２Ａ同士間の位置で側面が上記短手方向で没していて、後述の端子２０の弾性腕部２２の弾性変位を許容可能とする変位許容溝部１２Ｂが形成されている。該変位許容溝部１２Ｂは、図１および図２に見られるように、突壁部１２の両側面にそれぞれ形成されていて、該両側面の変位許容溝部１２Ｂは、該突壁部１２の上部では、上端から下方に向け延びる隔壁部１２Ｃによって短手方向（図２での左右方向）で隔てられていて、それぞれ上下方向に延びる溝部をなしており、下部では、両方の変位許容溝部１２Ｂが上記短手方向で互いに連通して、下方に開放された一つのスリット状の空間を形成している。   The protruding wall portion 12 has a side surface that is submerged in the short direction at a position between adjacent restricting protruding portions 12A, and a displacement-permissible groove portion that allows an elastic displacement of an elastic arm portion 22 of a terminal 20 described later. 12B is formed. As shown in FIGS. 1 and 2, the displacement-permissible groove portion 12B is formed on both side surfaces of the projecting wall portion 12, and the displacement-permissible groove portion 12B on both side surfaces is formed on the upper portion of the projecting wall portion 12. 2 are separated in the short direction (left-right direction in FIG. 2) by partition walls 12C extending downward from the upper end, and each form a groove extending in the up-down direction. One slit-shaped space opened downward is communicated with each other in the short direction.

Has been. The terminal 20 has an inverted U-shaped held portion 21 held on the side wall 13 of the housing 10 and an elastic member having a free end extending in the vertical direction near the protruding wall portion 12 in the short direction of the housing 10. A base portion 23 that connects the arm portion 22 and one leg portion (an inner leg portion 21A described later) of the held portion 21 and the elastic arm portion 22 that is held in the bottom wall 11 of the housing 10 and extends in the short-side direction. And a connecting portion 24 that extends from the other leg portion (outer leg portion 21B described later) of the held portion 21 to the outside of the housing 10 and is solder-connected to a corresponding circuit portion on the circuit board. As often seen in FIGS. 1 and 2, the terminal 20 is held by the held portion 21 and the base portion 23 by integral molding with the housing 10.

上記弾性腕部２２は、上記基部２３から移行部２５を経て屈曲されていて上記突壁部１２に沿って上方へ向けて延びており、その板厚方向での撓みにより、上記短手方向に弾性変位可能となっている。弾性腕部２２は、その自由端側たる上端部分が側壁１３に向けて凸湾曲して、後述する相手コネクタ２の相手端子５０と接触するための接触部２２Ａとして形成されている。上記接触部２２Ａの湾曲頂部は、上記短手方向でハウジング１０の規制突部１２Ａの突出頂部よりも突出している。   The elastic arm portion 22 is bent from the base portion 23 through the transition portion 25 and extends upward along the protruding wall portion 12, and is bent in the lateral direction by bending in the plate thickness direction. Elastic displacement is possible. The elastic arm portion 22 is formed as a contact portion 22 </ b> A for the upper end portion on the free end side thereof to bend toward the side wall 13 so as to contact a mating terminal 50 of the mating connector 2 described later. The curved top portion of the contact portion 22A protrudes from the protruding top portion of the restricting protrusion 12A of the housing 10 in the short direction.

基部２３は、図１に見られるように、ハウジング１０の底壁１１に一体モールド成形により保持されている。該基部２３は、該基部２３の上面と底壁１１の上面とが同一レベル面を形成していて、該基部２３の上面が受入凹部１５に露呈し、該上面より下方部分が底壁１１に埋没している。   As shown in FIG. 1, the base 23 is held on the bottom wall 11 of the housing 10 by integral molding. In the base 23, the upper surface of the base 23 and the upper surface of the bottom wall 11 form the same level surface, the upper surface of the base 23 is exposed to the receiving recess 15, and the lower part of the base 23 is exposed to the bottom wall 11. Buried.

被保持部２１は、図２によく見られるように、上述したように逆Ｕ字状をなしており、側壁１３の内側面に沿って上下方向に延びる一方の脚部２１Ａ（以下「内側脚部２１Ａ」という）と、上記短手方向にて上記内側脚部２１Ａよりも外側位置で上下方向に延びる他方の脚部２１Ｂ（以下「外側脚部２１Ｂ」という）と、上記内側脚部２１Ａの上端２１Ａ−１と外側脚部２１Ｂの上端２１Ｂ−１とを連結する連結部２１Ｃとを有している。   As shown in FIG. 2, the held portion 21 has an inverted U shape as described above, and has one leg portion 21 </ b> A (hereinafter referred to as “inner leg”) extending in the vertical direction along the inner surface of the side wall 13. Portion 21A ”), the other leg portion 21B (hereinafter referred to as“ outer leg portion 21B ”) extending in the vertical direction at a position outside the inner leg portion 21A in the short direction, and the inner leg portion 21A. It has a connecting portion 21C that connects the upper end 21A-1 and the upper end 21B-1 of the outer leg 21B.

上記内側脚部２１Ａは、受入凹部１５内に向けて露呈して、その上端２１Ａ−１寄り位置にて上記接触部２２Ａと対向するように受入凹部１５内に突出するロック部２１Ａ−３が形成されている。図１に見られるように、該ロック部２１Ａ−３は、例えば、プレス加工等により形成されており、その幅寸法（ハウジングの長手方向での寸法）は上記内側脚部２１Ａの幅寸法より小さくなっている（図１参照）。該ロック部２１Ａ−３は、後述する相手コネクタ２の相手端子５０の被ロック部５１Ｂ−１に係止することにより、コネクタ嵌合状態を維持してコネクタの抜けを防止するとともに、該被ロック部５１Ｂ−１との係止時に接触して電気的に導通することにより、上記接触部２２Ａを補助する役割も果たす。   The inner leg portion 21A is exposed toward the receiving recess 15 and is formed with a lock portion 21A-3 protruding into the receiving recess 15 so as to face the contact portion 22A at a position near the upper end 21A-1. Has been. As shown in FIG. 1, the lock portion 21A-3 is formed by, for example, press working or the like, and its width dimension (dimension in the longitudinal direction of the housing) is smaller than the width dimension of the inner leg portion 21A. (See FIG. 1). The locking portion 21A-3 is engaged with a locked portion 51B-1 of a mating terminal 50 of the mating connector 2 to be described later, thereby maintaining the connector fitting state and preventing the connector from being pulled out. It also plays a role of assisting the contact portion 22A by contacting and electrically conducting at the time of locking with the portion 51B-1.

上記外側脚部２１Ｂは、図１，２に見られるように、ハウジング１０の短手方向にて側壁１３の範囲内に位置しており、上端２１Ｂ−１から下端２１Ｂ−２に向け内側脚部２１Ａに近づくように傾斜して、下端２１Ｂ−２が上端２１Ｂ−１よりも上記短手方向で内側に位置している。図２によく見られるように、外側脚部２１Ｂは、上記短手方向にて、下端２１Ｂ−２の一部が内側脚部２１Ａと重複して位置している。   As shown in FIGS. 1 and 2, the outer leg portion 21B is located within the side wall 13 in the short direction of the housing 10, and the inner leg portion extends from the upper end 21B-1 toward the lower end 21B-2. It inclines so that it may approach 21A, and lower end 21B-2 is located inside in the said transversal direction rather than upper end 21B-1. As is often seen in FIG. 2, the outer leg 21B is positioned such that a part of the lower end 21B-2 overlaps the inner leg 21A in the short direction.

上記被保持部２１が側壁１３に一体モールド成形により保持された状態において、上記内側脚部２１Ａは、両側端面（ハウジングの長手方向での両側の端面）と外側脚部２１Ｂに対向する板面とが側壁１３に接面保持されていて、側壁１３から露呈した板面が、側壁１３の内側面と同一の面をなすように位置している。また、外側脚部２１Ｂおよび連結部２１Ｃは、側壁１３に埋設保持されている。   In a state where the held portion 21 is held on the side wall 13 by integral molding, the inner leg portion 21A includes both side end surfaces (end surfaces on both sides in the longitudinal direction of the housing) and a plate surface facing the outer leg portion 21B. Is held in contact with the side wall 13, and the plate surface exposed from the side wall 13 is positioned so as to form the same surface as the inner side surface of the side wall 13. Further, the outer leg portion 21 </ b> B and the connecting portion 21 </ b> C are embedded and held in the side wall 13.

接続部２４は、図１および図２に見られるように、既述の側壁１３の下端直下に形成された空間で上記短手方向での外側へ向けて屈曲されて延びており、該接続部２４の下面が底壁１１の下面とほぼ同じ高さに位置していて、回路基板の対応回路部との半田接続が可能となっている。図２によく見られるように、該接続部２４の先端（自由端）は、外側から見て目視可能な程度に、上記短手方向にて側壁１３の外側面の位置よりも若干外側に位置している。   As shown in FIGS. 1 and 2, the connecting portion 24 is bent and extended outward in the lateral direction in the space formed immediately below the lower end of the side wall 13 described above. The lower surface of 24 is positioned at substantially the same height as the lower surface of the bottom wall 11, and solder connection with the corresponding circuit portion of the circuit board is possible. As is often seen in FIG. 2, the distal end (free end) of the connecting portion 24 is located slightly outside the position of the outer surface of the side wall 13 in the short direction so that it can be seen from the outside. doing.

上述したように、上記外側脚部２１Ｂは、上端２１Ｂ−１から下端２１Ｂ−２に向け内側脚部２１Ａに近づくように傾斜しているので、該外側脚部２１Ｂの下端２１Ｂ−２から上記短手方向での外側へ向けて延びる接続部２４は、図１，２に見られるように、その一部が該短手方向で外側脚部２１Ｂと重複する範囲内に位置している。したがって、従来のような、外側脚部が内側脚部と平行に上下方向で真っ直ぐに延び、該外側脚部の下端から接続部がハウジング外へ延出している場合と比較して、本実施形態では、接続部２４が、外側脚部２１Ｂと重複して位置している分だけ、上記短手方向で内側に位置する。   As described above, the outer leg portion 21B is inclined so as to approach the inner leg portion 21A from the upper end 21B-1 toward the lower end 21B-2, so that the short end from the lower end 21B-2 of the outer leg portion 21B is shortened. As shown in FIGS. 1 and 2, a part of the connecting portion 24 extending outward in the hand direction is located within a range overlapping with the outer leg 21 </ b> B in the short direction. Therefore, as compared with the conventional case where the outer leg portion extends straight in the vertical direction parallel to the inner leg portion, and the connection portion extends out of the housing from the lower end of the outer leg portion, this embodiment. Then, the connection part 24 is located on the inner side in the short direction as much as the overlapping with the outer leg part 21B.

この結果、接続部２４の長さを変えなくても、該接続部２４は、ハウジング外に位置する部分の長さが短くなるので、上記短手方向でコネクタ１を小さくすることができる。また、既述したように、外側脚部２１Ｂの下端２１Ｂ−２の一部が上記短手方向で内側脚部２１Ａと重複して位置しているので、その重複した分だけ、接続部２４を、さらに上記短手方向で内側に位置させることができ、接続部２４のハウジング１０外方へ延出する部分の長さを短くできる。したがって、上記短手方向でコネクタをさらに小さくできる。また、本実施形態に代えて、外側脚部２１Ｂの下端２１Ｂ−２の一部でなく全部が上記短手方向で内側脚部２１Ａと重複して位置するような構成とすれば、コネクタ１を上記短手方向でさらに小型化できることは言うまでもない。   As a result, even if the length of the connecting portion 24 is not changed, the length of the portion of the connecting portion 24 located outside the housing is shortened, so that the connector 1 can be reduced in the short direction. Further, as described above, a part of the lower end 21B-2 of the outer leg portion 21B is overlapped with the inner leg portion 21A in the short direction, so that the connecting portion 24 is provided by the overlapped portion. Furthermore, it can be located inside in the short direction, and the length of the portion of the connecting portion 24 extending outward from the housing 10 can be shortened. Therefore, the connector can be further reduced in the short direction. Further, instead of the present embodiment, if the configuration is such that not all of the lower end 21B-2 of the outer leg 21B but all of them overlap with the inner leg 21A in the short direction, the connector 1 is Needless to say, the size can be further reduced in the short direction.

本実施形態では、接続部２４自体の長さは従来のものと比較して短くならないので、該接続部２４が回路基板と半田接続された状態において、コネクタ１と回路基板との電気的な導通は不安定にならず、回路基板へのコネクタ１の固定強度が低下することもない。   In the present embodiment, since the length of the connecting portion 24 itself is not shortened compared to the conventional one, the electrical continuity between the connector 1 and the circuit board in a state where the connecting portion 24 is solder-connected to the circuit board. Does not become unstable, and the fixing strength of the connector 1 to the circuit board does not decrease.

固定金具３０は、金属板条片を板厚方向に屈曲して作られていて、コネクタ１の平面形状における四隅に設けられている。該固定金具３０は、一体モールド成形により端壁１４に保持される被保持部（図示せず）と、該被保持部の下端で屈曲され上記短手方向で外側へ向けて延びる固定部３１とを有している。該固定金具３０は、固定部３１が回路基板の上面に半田固定されることにより、回路基板へのコネクタ１の固定強度の向上に寄与する。該固定部３１の先端（自由端）は、上記短手方向にて端子２０の接続部の先端と同位置にある。   The fixing bracket 30 is made by bending a metal plate strip in the plate thickness direction, and is provided at four corners in the planar shape of the connector 1. The fixing bracket 30 includes a held portion (not shown) held by the end wall 14 by integral molding, and a fixing portion 31 that is bent at the lower end of the held portion and extends outward in the short direction. have. The fixing bracket 30 contributes to the improvement of the fixing strength of the connector 1 to the circuit board by fixing the fixing portion 31 to the upper surface of the circuit board by soldering. The distal end (free end) of the fixing portion 31 is at the same position as the distal end of the connection portion of the terminal 20 in the short direction.

［相手コネクタの構成］
図２に示される相手コネクタ２は、他の回路基板（図示せず）に取り付けられるコネクタであって、コネクタ１の受入凹部１５に適合した枠状の嵌合部を有しており、該嵌合部が上記受入凹部１５内に嵌入することにより、コネクタ同士が嵌合接続されるようになっている。該相手コネクタ２は、図２に示されるように、略直方体外形の合成樹脂製のハウジング４０と、該ハウジング４０の長手方向で該ハウジング４０に一体モールド成形により配列保持される複数の金属製の端子５０（以下、「相手端子５０」という）とを有している。 [Configuration of mating connector]
The mating connector 2 shown in FIG. 2 is a connector that is attached to another circuit board (not shown), and has a frame-like fitting portion that fits into the receiving recess 15 of the connector 1. When the joint portion is inserted into the receiving recess 15, the connectors are fitted and connected. As shown in FIG. 2, the mating connector 2 is made of a synthetic resin housing 40 having a substantially rectangular parallelepiped outer shape, and a plurality of metal plates arranged and held in the housing 40 by integral molding in the longitudinal direction of the housing 40. And a terminal 50 (hereinafter referred to as “mating terminal 50”).

ハウジング４０は、上記他の回路基板に対面する底壁４１と該底壁４１から起立する周壁とを有しており、該底壁４１と周壁によって囲まれ図２での下方に開口する空間が、コネクタ嵌合状態でコネクタ１のハウジング１０の突壁部１２を受け入れる受入凹部４５として形成されている。上記周壁は、互いに対向して上記長手方向に延びる二つの側壁４３を有しており、該側壁４３が相手端子５０を配列保持している。   The housing 40 has a bottom wall 41 facing the other circuit board and a peripheral wall rising from the bottom wall 41. A space surrounded by the bottom wall 41 and the peripheral wall and opened downward in FIG. The receiving recess 45 is formed so as to receive the protruding wall 12 of the housing 10 of the connector 1 in the connector fitting state. The peripheral wall has two side walls 43 that face each other and extend in the longitudinal direction, and the side walls 43 hold the mating terminals 50 in an array.

相手端子５０は、金属板条片を板厚方向に屈曲して作られており、ハウジング４０の短手方向（図２での左右方向）で対称な二列をなして該ハウジング４０の長手方向に配列された状態で上記ハウジング４０に保持されている。上記側壁４３に保持されるＵ字状の嵌入部５１と、該嵌入部５１の二つの脚部のうち受入凹部４５側に位置する一方の脚部５１Ａ（以下、「内側脚部５１Ａ」という）から、屈曲された移行部５５を経て上記短手方向に延び上記他の回路基板の対応回路部に半田接続される接続部５４とを有している。図２によく見られるように、相手端子５０は、上記嵌入部５１および移行部５５で、ハウジング４０との一体モールド成形により保持されている。   The mating terminal 50 is made by bending a metal plate strip in the plate thickness direction, and forms two symmetrical rows in the short direction (left and right direction in FIG. 2) of the housing 40 in the longitudinal direction of the housing 40. Are held in the housing 40 in a state of being arranged in a row. The U-shaped fitting part 51 held by the side wall 43 and one leg part 51A located on the receiving concave part 45 side of the two leg parts of the fitting part 51 (hereinafter referred to as “inner leg part 51A”). And a connecting portion 54 that extends in the short direction through the bent transition portion 55 and is solder-connected to the corresponding circuit portion of the other circuit board. As is often seen in FIG. 2, the mating terminal 50 is held at the fitting portion 51 and the transition portion 55 by integral molding with the housing 40.

上記嵌入部５１は、側壁４３を下方から跨ぐようにして該側壁４３に埋没されている。該嵌入部５１は、Ｕ字状部分の内側板面および側縁が側壁４３に保持されていて、該側壁４３から露呈した上記Ｕ字状部分の外側板面が、側壁４３の外面と同一の面をなすように位置している。ハウジング４０の短手方向（図２での左右方向）での上記嵌入部５１の寸法は、コネクタ１の端子２０の接触部２２Ａとロック部２１Ａ−３との間隔よりも若干大きくなっている。   The fitting portion 51 is buried in the side wall 43 so as to straddle the side wall 43 from below. In the fitting portion 51, the inner plate surface and the side edge of the U-shaped portion are held by the side wall 43, and the outer plate surface of the U-shaped portion exposed from the side wall 43 is the same as the outer surface of the side wall 43. It is located so as to make a plane. The dimension of the fitting portion 51 in the short direction of the housing 40 (left and right direction in FIG. 2) is slightly larger than the distance between the contact portion 22A of the terminal 20 of the connector 1 and the lock portion 21A-3.

上記嵌入部５１の内側脚部５１Ａの、受入凹部４５側に位置して露呈する板面は、底壁４１寄り位置（図２での上側位置）の部分が、コネクタ嵌合状態にてコネクタ１の端子２０の接触部２２Ａと接圧をもって接触する対応接触部５１Ａ−１として形成されている。また、上記嵌入部５１の他方の脚部５１Ｂ（以下、「外側脚部５１Ｂ」という）の、受入凹部４５から離れて位置する板面は、底壁４１寄り位置（図２での上側位置）の部分が没して凹部が形成されていて、該凹部が上記端子２０のロック部２１Ａ−３と係止する被ロック部５１Ｂ−１として機能する。   The plate surface of the inner leg portion 51A of the fitting portion 51 that is exposed on the receiving recess 45 side is exposed to the connector 1 when the portion close to the bottom wall 41 (upper position in FIG. 2) is in the connector fitting state. The corresponding contact portion 51A-1 is in contact with the contact portion 22A of the terminal 20 with contact pressure. Further, the plate surface of the other leg 51B (hereinafter referred to as “outer leg 51B”) of the fitting portion 51 that is located away from the receiving recess 45 is a position closer to the bottom wall 41 (upper position in FIG. 2). Is recessed to form a recessed portion, and the recessed portion functions as a locked portion 51B-1 that engages with the locking portion 21A-3 of the terminal 20.

接続部５４は、図２に見られるように、該接続部５４の下面（図２での上面）が底壁４１の下面（図２での上面）とほぼ同じ高さに位置していて、回路基板の対応回路部との半田接続が可能となっている。   As shown in FIG. 2, the connection portion 54 has a lower surface (upper surface in FIG. 2) of the connection portion 54 located substantially at the same height as a lower surface of the bottom wall 41 (upper surface in FIG. 2). Solder connection with the corresponding circuit part of the circuit board is possible.

［コネクタの嵌合動作］
以下、コネクタ１と相手コネクタ２との嵌合動作について説明する。まず、コネクタ１の端子２０そして固定金具３０および相手コネクタ２の端子５０をそれぞれ対応する回路基板に半田接続する。次に、図２に見られるように、コネクタ１を受入凹部１５が上方へ開口した姿勢とするとともに、相手コネクタ２を受入凹部４５が下方へ開口した姿勢として該コネクタ１の上方位置へもたらす。そして、図２にて矢印で示されるように、相手コネクタ２を下方へ移動させ、相手コネクタ２の嵌合部をコネクタ１の受入凹部４５内へ嵌入させる。 [Connector mating operation]
Hereinafter, the fitting operation between the connector 1 and the mating connector 2 will be described. First, the terminal 20 of the connector 1, the fixing bracket 30, and the terminal 50 of the mating connector 2 are soldered to the corresponding circuit boards. Next, as shown in FIG. 2, the connector 1 is brought into an attitude in which the receiving recess 15 is opened upward, and the mating connector 2 is brought to an upper position of the connector 1 in an attitude in which the receiving recess 45 is opened downward. Then, as shown by an arrow in FIG. 2, the mating connector 2 is moved downward, and the fitting portion of the mating connector 2 is fitted into the receiving recess 45 of the connector 1.

この結果、相手コネクタ２の相手端子５０の嵌入部５１は、コネクタ１の端子２０の接触部２２Ａおよびロック部２１Ａ−３との間を押し拡げて進入する。そして、接触部２２Ａが変位許容溝部１２Ｂ内へ向けて押圧されることにより、弾性腕部２２が該変位許容溝部１２Ｂ内へ進入するように弾性変位する。さらに、嵌入部５１の進入が進行すると、上記接触部２２Ａが上記嵌入部５１の対応接触部５１Ａ−１と接圧をもって接触するとともに、上記ロック部２１Ａ−３が該嵌入部５１の被ロック部５１Ｂ−１と上下方向で係止する。この結果、コネクタの端子同士が電気的に導通するとともに互いにロックされ、コネクタ同士の嵌合接続が完了する。   As a result, the fitting portion 51 of the mating terminal 50 of the mating connector 2 enters between the contact portion 22A and the lock portion 21A-3 of the terminal 20 of the connector 1 while expanding. When the contact portion 22A is pressed toward the displacement allowable groove portion 12B, the elastic arm portion 22 is elastically displaced so as to enter the displacement allowable groove portion 12B. Further, when the insertion of the insertion portion 51 proceeds, the contact portion 22A comes into contact with the corresponding contact portion 51A-1 of the insertion portion 51 with a contact pressure, and the lock portion 21A-3 is a locked portion of the insertion portion 51. Locks with 51B-1 in the vertical direction. As a result, the terminals of the connectors are electrically connected and locked to each other, and the fitting connection between the connectors is completed.

上述したように、相手コネクタ２の嵌入部５１はコネクタ１の端子２０の接触部２２Ａおよびロック部２１Ａ−３との間を押し拡げて進入するので、コネクタ嵌合時において、コネクタ１の内側脚部２１Ａは、該嵌入部５１からハウジング１０の短手方向で外側へ向けた押圧力を受け、既述したように側壁１３が下部を支点として外側へ撓む。   As described above, since the fitting portion 51 of the mating connector 2 enters between the contact portion 22A of the terminal 20 of the connector 1 and the lock portion 21A-3, the inner leg of the connector 1 is fitted when the connector is fitted. The portion 21A receives a pressing force directed outward in the short direction of the housing 10 from the fitting portion 51, and as described above, the side wall 13 bends outward with the lower portion as a fulcrum.

本実施形態では、外側脚部２１Ｂの下端２１Ｂ−２が上端２１Ｂ−１よりも上記短手方向で内側、すなわち内側脚部２１Ａ寄りに位置していて、内側脚部２１Ａの下端２１Ａ−２と外側脚部２１Ｂの下端２１Ｂ−２との間隔が小さいので、外側脚部２１Ｂが生じる対抗モーメントが作用しにくい。したがって、側壁１３そして内側脚部２１Ａはそれらの下部を支点として外側へ撓みやすいので、コネクタ嵌合時において相手コネクタ２の挿入に必要な挿入力を小さくすることができる。   In the present embodiment, the lower end 21B-2 of the outer leg 21B is located on the inner side in the short direction than the upper end 21B-1, that is, closer to the inner leg 21A, and the lower end 21A-2 of the inner leg 21A Since the distance between the outer leg 21B and the lower end 21B-2 is small, the counter-moment generated by the outer leg 21B is difficult to act. Therefore, since the side wall 13 and the inner leg portion 21A are easily bent outward with their lower portions as fulcrums, the insertion force required for inserting the mating connector 2 when the connector is fitted can be reduced.

＜第二実施形態＞
本実施形態は、端子がハウジングの側壁へ上方から圧入されて該ハウジングに保持されている点で、該端子が一体モールド成形によってハウジングに保持されている第一実施形態と異なっている。 <Second embodiment>
This embodiment is different from the first embodiment in which the terminal is held in the housing by integral molding, in that the terminal is press-fitted into the side wall of the housing from above and held in the housing.

図３（Ａ）は、第二実施形態に係るコネクタの斜視図であり、ハウジング長手方向における端子の位置での断面を示しており、図３（Ｂ）は、図３（Ａ）のコネクタの断面をハウジング長手方向から見た図である。本実施形態に係るコネクタ３は、ハウジング６０の側壁６３へ端子７０を上方から圧入保持した構成となっている。図３（Ａ），（Ｂ）では、端子７０について、第一実施形態の端子２０の各部分と対応する部分に、該端子２０の各部分の符号に「５０」を加えた符号を付している。   FIG. 3A is a perspective view of the connector according to the second embodiment, showing a cross-section at the position of the terminal in the longitudinal direction of the housing, and FIG. 3B is a view of the connector of FIG. It is the figure which looked at the cross section from the housing longitudinal direction. The connector 3 according to the present embodiment has a configuration in which the terminal 70 is press-fitted and held from above on the side wall 63 of the housing 60. 3 (A) and 3 (B), with respect to the terminal 70, a part corresponding to each part of the terminal 20 of the first embodiment is given a reference sign obtained by adding “50” to the reference sign of each part of the terminal 20. ing.

本実施形態におけるハウジング６０は、底壁６１、突壁部６２、側壁６３、端壁６４および受入凹部６５を有しており、基本的な形状は第一実施形態のハウジング１０と同様であるが、本実施形態の底壁６１、突壁部６２および側壁６３の形状が第一実施形態の上記底壁１１、突壁部１２、側壁１３の形状と異なっている。ここでは、上記底壁６１、突壁部６２および側壁６３の形状を中心に説明する。   The housing 60 in this embodiment has a bottom wall 61, a protruding wall portion 62, a side wall 63, an end wall 64, and a receiving recess 65, and the basic shape is the same as that of the housing 10 of the first embodiment. The shapes of the bottom wall 61, the protruding wall portion 62, and the side wall 63 of the present embodiment are different from the shapes of the bottom wall 11, the protruding wall portion 12, and the side wall 13 of the first embodiment. Here, the shape of the bottom wall 61, the protruding wall portion 62, and the side wall 63 will be mainly described.

底壁６１は、図３（Ａ），（Ｂ）に見られるように、ハウジング６０の短手方向（図３（Ｂ）の左右方向）にて、互いに対向する二つの側壁６３の内側面同士間にわたる範囲の全域で延びており、ハウジング６０の長手方向での端子７０の位置において、第一実施形態のように上記短手方向での中央位置にて外部と連通するように上下方向で貫通してはいない。また、該底壁６１は、図３によく見られるように、上記短手方向での両端が側壁６３の下方までは及んでおらず、該側壁６３の下方に形成される空間に、後述の端子７０の接続部７４が位置している。また、該底壁６１の上面には、上記短手方向で受入凹部６５に対応する位置に、後述の端子７０の基部７３を収容するための底溝６１Ａが上記短手方向に延びて形成されている。   As can be seen in FIGS. 3 (A) and 3 (B), the bottom wall 61 is formed between two inner surfaces of two side walls 63 facing each other in the short direction of the housing 60 (left and right direction in FIG. 3 (B)). It extends over the entire range, and penetrates in the vertical direction so that it communicates with the outside at the central position in the short direction at the position of the terminal 70 in the longitudinal direction of the housing 60 as in the first embodiment. Not done. Further, as can be seen in FIG. 3, the bottom wall 61 does not reach the lower side of the side wall 63 at both ends in the short side direction, and will be described later in a space formed below the side wall 63. The connection part 74 of the terminal 70 is located. Further, a bottom groove 61A for accommodating a base portion 73 of a terminal 70 described later is formed on the upper surface of the bottom wall 61 at a position corresponding to the receiving recess 65 in the short direction, extending in the short direction. ing.

突壁部６２は、上記長手方向での端子７０に対応する位置にて、両側面が上下方向全域にわたり受入空間６５に向け開口して没する溝部を有している。この溝部を形成することで、互いに隣接する端子７０同士間に対応する位置で、上下方向全域にわたって延び受入空間６５に向け突出する条壁部６２Ａが形成されている。該条壁部６２Ａは、第一実施形態の規制突部１２Ａと同様に、上記短手方向での端子７０の弾性腕部７２の「へたり」を防止する機能を有している。また、上記突壁部６２は、互いに隣接する条壁部６２Ａ同士間、すなわち、上記長手方向で端子７０に対応する位置で上下方向全域にわたる上述の溝部が、端子７０の弾性腕部７２を収容するとともに、該弾性腕部７２の弾性変位を許容可能とする変位許容溝部６２Ｂとして形成されている。   The protruding wall portion 62 has a groove portion whose both side surfaces open and sink toward the receiving space 65 over the entire vertical direction at a position corresponding to the terminal 70 in the longitudinal direction. By forming this groove portion, a strip wall portion 62 </ b> A that extends over the entire vertical direction and protrudes toward the receiving space 65 is formed at a position corresponding to between the terminals 70 adjacent to each other. The strip wall portion 62A has a function of preventing the “sagging” of the elastic arm portion 72 of the terminal 70 in the short direction, similarly to the restricting projection portion 12A of the first embodiment. Further, the protruding wall portion 62 accommodates the elastic arm portion 72 of the terminal 70 between the adjacent strip wall portions 62 </ b> A, that is, the above-described groove portion extending in the entire vertical direction at a position corresponding to the terminal 70 in the longitudinal direction. In addition, the elastic arm portion 72 is formed as a displacement-permissible groove portion 62B that allows the elastic displacement.

側壁６３は、上記長手方向で端子７０と対応する位置にて、上下方向に貫通して延びる端子保持溝６３Ａが形成されている。後述するように、該端子保持溝６３Ａは、上記長手方向で対向する二つの溝内面に対して端子７０の被保持部７１が上方から圧入されて、該被保持部７１を該溝内面で保持するようになっている。該端子保持溝６３Ａと、底壁６１の底溝６１Ａと、突壁部６２の変位許容溝６２Ｂとは互いに連通して、全体としてＵ字状の溝部を形成しており、該溝部が端子７０を収容するための端子収容溝として機能している。   The side wall 63 is formed with a terminal holding groove 63 </ b> A extending through in the vertical direction at a position corresponding to the terminal 70 in the longitudinal direction. As will be described later, in the terminal holding groove 63A, the held portion 71 of the terminal 70 is press-fitted from above into the two groove inner surfaces opposed in the longitudinal direction, and the held portion 71 is held by the groove inner surface. It is supposed to be. The terminal holding groove 63A, the bottom groove 61A of the bottom wall 61, and the displacement allowance groove 62B of the protruding wall portion 62 communicate with each other to form a U-shaped groove portion as a whole. It functions as a terminal accommodating groove for accommodating the.

端子７０は、突壁部１２に対して対称な二列をなしてハウジング６０の長手方向に配列された状態で上記ハウジング６０に保持されている。該端子７０は、金属板条片を板厚方向で略横Ｓ字状に屈曲して作られていて、逆Ｕ字状部７１、弾性腕部７２、基部７３および接続部７４を有している点で、第一実施形態の端子２０と基本的な構成は同じである。上記端子７０の逆Ｕ字状部７１は、第一実施形態の被保持部２１と同様に、内側脚部７１Ａ、外側脚部７１Ｂおよび連結部７１Ｃを有している。   The terminals 70 are held by the housing 60 in a state where the terminals 70 are arranged in the longitudinal direction of the housing 60 in two rows symmetrical to the protruding wall portion 12. The terminal 70 is formed by bending a metal strip into a substantially horizontal S shape in the thickness direction, and has an inverted U-shaped portion 71, an elastic arm portion 72, a base portion 73, and a connecting portion 74. In that respect, the basic configuration is the same as the terminal 20 of the first embodiment. The inverted U-shaped portion 71 of the terminal 70 has an inner leg portion 71A, an outer leg portion 71B, and a connecting portion 71C, similarly to the held portion 21 of the first embodiment.

上記外側脚部７１Ｂは、図３（Ｂ）によく見られるように、ハウジング６０の短手方向（図３（Ｂ）にて左右方向）にてハウジング６０の側壁６３の範囲内に位置しており、上端７１Ｂ−１から下端７１Ｂ−２に向け内側脚部７１Ａに近づくように傾斜して、下端７１Ｂ−２が上端７１Ｂ−１よりも上記短手方向で内側に位置している。したがって、該外側脚部７１Ｂの下端７１Ｂ−２から上記短手方向で外側へ向けて延びる接続部７４は、第一実施形態と同様に、その一部が該短手方向で外側脚部７１Ｂと重複する範囲内に位置している。この結果、接続部７４が、外側脚部７１Ｂと重複して位置している分だけ上記短手方向で内側に位置し、その分、上記短手方向でコネクタ３を小さくすることができる。   The outer leg 71B is located within the range of the side wall 63 of the housing 60 in the short direction of the housing 60 (left and right in FIG. 3B), as can be seen in FIG. 3B. The upper end 71B-1 is inclined so as to approach the inner leg 71A from the upper end 71B-1 toward the lower end 71B-2, and the lower end 71B-2 is located on the inner side in the short direction than the upper end 71B-1. Therefore, the connecting portion 74 extending outward in the short direction from the lower end 71B-2 of the outer leg 71B is partially connected to the outer leg 71B in the short direction, as in the first embodiment. It is located within the overlapping range. As a result, the connection portion 74 is positioned inward in the short direction by the amount overlapping with the outer leg portion 71B, and the connector 3 can be made smaller in the short direction accordingly.

本実施形態では、外側脚部７１Ｂの下端７１Ｂ−２が上記短手方向にて内側脚部７１Ａと重複しておらず、この点で、外側脚部２１Ｂの下端２１Ｂ−２の一部が内側脚部２１Ａと重複して位置している第一実施形態と異なっている。しかし、外側脚部７１Ｂの下端７１Ｂ−２を内側脚部７１Ａに重複するように位置させて、上記短手方向でのコネクタのさらなる小型化を図ることも可能であることは言うまでもない。   In this embodiment, the lower end 71B-2 of the outer leg 71B does not overlap the inner leg 71A in the short direction, and in this respect, a part of the lower end 21B-2 of the outer leg 21B is on the inner side. This is different from the first embodiment located overlapping the leg portion 21A. However, it goes without saying that it is possible to further reduce the size of the connector in the short direction by positioning the lower end 71B-2 of the outer leg 71B so as to overlap the inner leg 71A.

上記外側脚部７１Ｂは、図３（Ａ）に見られるように、両側端面（ハウジングの長手方向での両側の端面）から突出する被保持部としての圧入突部７１Ｂ−３を有している。本実施形態では、端子保持溝６３Ａに上方から圧入された外側脚部７１Ｂの圧入突部７１Ｂ−３が該端子保持溝６３Ａの互いに対向する二つの溝内面に喰い込むことにより、端子７０がハウジング６０に保持される。また、端子７０がハウジング６０に保持された状態において、該端子７０の逆Ｕ字状部７１、弾性腕部７２、基部７３は、それぞれハウジング６０の端子保持溝６３Ａ、変位許容溝部６２Ｂ、底溝６１Ａに収容される。本実施形態では、上記圧入突部７１Ｂ−３が外側脚部７１Ｂの両側端面に形成されていることとしたが、これに代えてあるいは該圧入突部７１Ｂ−３とともに、例えば、内側脚部７１Ａの両側端面や連結部７１Ｃの両側端面に圧入突部が形成されていてもよい。   As shown in FIG. 3A, the outer leg 71B has press-fitting protrusions 71B-3 as held parts that protrude from both end faces (end faces on both sides in the longitudinal direction of the housing). . In the present embodiment, the press fitting protrusion 71B-3 of the outer leg 71B press-fitted into the terminal holding groove 63A from above is bitten into the inner surfaces of the two opposite holding grooves 63A, whereby the terminal 70 is housed in the housing. 60. Further, in a state where the terminal 70 is held by the housing 60, the inverted U-shaped portion 71, the elastic arm portion 72, and the base portion 73 of the terminal 70 are the terminal holding groove 63A, the displacement allowable groove portion 62B, and the bottom groove of the housing 60, respectively. 61A. In the present embodiment, the press-fitting protrusion 71B-3 is formed on both end faces of the outer leg 71B. Instead of this or together with the press-fitting protrusion 71B-3, for example, the inner leg 71A. The press-fitting protrusions may be formed on both side end surfaces and on both side end surfaces of the connecting portion 71C.

本実施形態においても、第一実施形態と同様に、外側脚部７１Ｂの下端７１Ｂ−２が上端７１Ｂ−１よりも上記短手方向で内側、内側脚部７１Ａ寄りに位置していて、コネクタ嵌合時に、ハウジング６０の側壁がその下部を支点として相手コネクタ（図示せず）の外側へ撓みやすくなっているので、該相手コネクタの挿入力を小さくすることができる。   Also in the present embodiment, as in the first embodiment, the lower end 71B-2 of the outer leg 71B is located closer to the inner side and the inner leg 71A in the short direction than the upper end 71B-1, and the connector is fitted. At the time, the side wall of the housing 60 is easily bent to the outside of the mating connector (not shown) with the lower portion as a fulcrum, so that the insertion force of the mating connector can be reduced.

＜第三実施形態＞
第三実施形態は、端子がハウジングへ下方から圧入される点で、端子が上方から圧入される第二実施形態と異なっている。本実施形態のコネクタは、ハウジングの底壁と突壁部を除き、第二実施形態のコネクタと構成が同じである。以下、ハウジングについては、第二実施形態と同じ部分には第二実施形態の符号に「２０」を加えた符号を付して説明を省略し、上記底壁および突壁部の構成を中心に説明する。また、本実施形態の端子は、第二実施形態の端子と全く同じ形状であるので、第二実施形態と同じ符号を付して説明を省略する。 <Third embodiment>
The third embodiment is different from the second embodiment in which the terminal is press-fitted from above in that the terminal is press-fitted into the housing from below. The connector of the present embodiment has the same configuration as the connector of the second embodiment except for the bottom wall and the protruding wall portion of the housing. Hereinafter, for the housing, the same parts as those of the second embodiment are denoted by reference numerals obtained by adding “20” to the reference numerals of the second embodiment, and the description thereof will be omitted. The configuration of the bottom wall and the protruding wall portion will be mainly described. explain. Moreover, since the terminal of this embodiment is the completely same shape as the terminal of 2nd embodiment, the same code | symbol as 2nd embodiment is attached | subjected and description is abbreviate | omitted.

図４（Ａ）は、本実施形態に係るコネクタ４の斜視図であり、ハウジング８０の長手方向における端子７０の位置での断面を示しており、図４（Ｂ）は、図４（Ａ）のコネクタ４の断面をハウジング８０の長手方向から見た図である。図４（Ａ），（Ｂ）に見られるように、本実施形態に係るコネクタ４のハウジング８０の底壁８１は、該ハウジング８０の長手方向で端子７０に対応する位置では、該ハウジング８０の短手方向（図４（Ｂ）での左右方向）での突壁部８２の中央位置にのみ形成されている。したがって、ハウジング８０は該突壁部８２の中央位置以外では下方に開放しており、下方からの端子７０の圧入を可能としている。本実施形態では、上記突壁部８２は上壁８２Ｃを有していて、上記長手方向に対して直角な断面がＴ字状をなしており、変位許容溝部８２Ｂの上部は該上壁８２Ｃによって塞がれている。   FIG. 4A is a perspective view of the connector 4 according to the present embodiment, showing a cross section at the position of the terminal 70 in the longitudinal direction of the housing 80, and FIG. 4B is FIG. FIG. 6 is a view of a cross section of the connector 4 as viewed from the longitudinal direction of the housing 80. 4A and 4B, the bottom wall 81 of the housing 80 of the connector 4 according to this embodiment is located at a position corresponding to the terminal 70 in the longitudinal direction of the housing 80. It is formed only at the center position of the protruding wall portion 82 in the short direction (left and right direction in FIG. 4B). Therefore, the housing 80 is opened downward except for the central position of the protruding wall portion 82, and the terminal 70 can be press-fitted from below. In the present embodiment, the protruding wall portion 82 has an upper wall 82C, a cross section perpendicular to the longitudinal direction has a T shape, and the upper portion of the displacement allowable groove portion 82B is formed by the upper wall 82C. It is blocked.

本実施形態も、第二実施形態と同様に、端子７０の逆Ｕ字状部７１がハウジング８０の側壁８３で圧入保持されていて、外側脚部７１Ｂの下端７１Ｂ−２が内側脚部７１Ａの下端７１Ａ−２に近づいて位置し、接続部７４の一部が上記短手方向で外側脚部７１Ｂと重複する範囲内に位置している。したがって、その重複している分だけ上記短手方向でコネクタ４を小さくすることができる。また、コネクタ嵌合時にて側壁が撓みやすくなるので、相手コネクタの挿入力を小さくすることができる。   In the present embodiment, similarly to the second embodiment, the inverted U-shaped portion 71 of the terminal 70 is press-fitted and held by the side wall 83 of the housing 80, and the lower end 71B-2 of the outer leg 71B is the inner leg 71A. It is located close to the lower end 71A-2, and a part of the connecting portion 74 is located within a range overlapping with the outer leg 71B in the short direction. Therefore, the connector 4 can be made smaller in the short direction by the overlapping amount. Moreover, since the side wall is easily bent when the connector is fitted, the insertion force of the mating connector can be reduced.

第一ないし第三実施形態では、互いに対向する二つの側壁部の両方で端子が配列保持されていることとしたが、これに代えて、一方の側壁部のみに端子が配列されていることとしてもよい。   In the first to third embodiments, the terminals are arranged and held on both of the two side wall portions facing each other. Instead, the terminals are arranged only on one side wall portion. Also good.

第一ないし第三実施形態では、本発明をレセプタクルコネクタに適用した例を説明したが、本発明を適用可能なコネクタはこれに限らず、例えば、図２に示される相手コネクタ２のようなプラグコネクタに適用することも可能である。この場合、例えば、第一ないし第三実施形態の端子から弾性腕部および基部を省略したような形状の端子をハウジングの側壁に保持させてもよい。   In the first to third embodiments, the example in which the present invention is applied to the receptacle connector has been described. However, the connector to which the present invention is applicable is not limited to this, for example, a plug such as the mating connector 2 shown in FIG. It is also possible to apply to connectors. In this case, for example, a terminal having a shape in which the elastic arm portion and the base portion are omitted from the terminals of the first to third embodiments may be held on the side wall of the housing.

第一ないし第三実施形態では、端子の外側脚部は、上端から下端に向かうにつれて内側脚部に近づくように傾斜することとしたが、これに代えて、外側脚部は、上端から下端に向け内側脚部に近づくように屈曲されていてもよい。例えば、外側脚部が上下方向での中間位置で屈曲され下側部分が内側脚部へ向けて傾斜して延びていてもよいし、外側脚部が中間位置でクランク状に屈曲され下側部分が内側脚部寄り位置で真っ直ぐに延びていてもよい。すなわち、外側脚部の下端が上端よりも内側に位置していればよい。   In the first to third embodiments, the outer leg of the terminal is inclined so as to approach the inner leg as it goes from the upper end to the lower end. Instead, the outer leg is changed from the upper end to the lower end. You may be bent so that it may approach a direction inner leg part. For example, the outer leg may be bent at an intermediate position in the vertical direction and the lower part may be inclined and extended toward the inner leg, or the outer leg may be bent in a crank shape at the intermediate position. May extend straight at the position near the inner leg. That is, it is only necessary that the lower end of the outer leg portion is positioned inside the upper end.
