Description

本発明は、基板用コネクタに関する。   The present invention relates to a board connector.

特許文献1には、基板用コネクタとしてのSMTコネクタ(表面実装型コネクタ)が開示されている。SMTコネクタは、樹脂製のケース(ハウジング)と、ケースの組付孔内に装着される固定部材としての金属製のペグとを備え、ペグがプリント配線板(回路基板)にはんだ付けにより固定されることで、プリント配線板に固定される。組付孔は、プリント配線板の板面とほぼ直交する縦方向に沿った挿通孔及び圧入孔を有し、ペグは、組付孔に縦方向に挿入される。   Patent Document 1 discloses an SMT connector (surface mount connector) as a board connector. The SMT connector includes a resin case (housing) and a metal peg as a fixing member mounted in the assembly hole of the case, and the peg is fixed to the printed wiring board (circuit board) by soldering. As a result, it is fixed to the printed wiring board. The assembly hole has an insertion hole and a press-fit hole along the vertical direction substantially orthogonal to the plate surface of the printed wiring board, and the peg is inserted into the assembly hole in the vertical direction.

特開2011−96438号公報JP 2011-96438 A

ところで、上記の場合、ペグの組付孔への装着方向が一方向のみに限定され、ペグに対してケースが専用部品化していた。このため、例えば、表面実装型からスルーホール型への仕様変更の要請がある場合には、別途金型を新設しなければならず、コストが高くつくという問題があった。   By the way, in the above case, the mounting direction of the peg into the assembly hole is limited to only one direction, and the case is a dedicated component for the peg. For this reason, for example, when there is a request to change the specification from the surface mount type to the through-hole type, there is a problem in that a new die must be newly installed, resulting in high costs.

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、仕様変更に容易に対応することができ、コスト高となるのを抑えることができる基板用コネクタを提供することを目的とする。   The present invention has been completed based on the above-described circumstances, and an object thereof is to provide a board connector that can easily cope with a specification change and suppress an increase in cost. To do.

本発明の基板用コネクタは、回路基板に電気的に接続される端子金具と、前記端子金具が装着されるハウジングと、前記ハウジングに装着されるハウジング装着部、及び前記回路基板に固定される基板固定部を有する固定部材とを備え、前記ハウジングには、前記回路基板の板面とほぼ直交する縦方向に延出して前記ハウジング装着部を前記縦方向に挿入可能となす縦挿入孔と、前記縦挿入孔と交差連通し、且つ前記回路基板の板面とほぼ平行な横方向の延出して前記ハウジング装着部を前記横方向に挿入可能となす横挿入孔とを有する固定部材受け部が設けられているところに特徴を有する。   The board connector of the present invention includes a terminal fitting electrically connected to a circuit board, a housing to which the terminal fitting is mounted, a housing mounting portion to be mounted on the housing, and a board to be fixed to the circuit board. A fixing member having a fixing portion, and the housing includes a vertical insertion hole extending in a vertical direction substantially orthogonal to a plate surface of the circuit board and allowing the housing mounting portion to be inserted in the vertical direction; There is provided a fixing member receiving portion having a lateral insertion hole that crosses the longitudinal insertion hole and extends in a lateral direction substantially parallel to the plate surface of the circuit board so that the housing mounting portion can be inserted in the lateral direction. It is characterized by

ハウジング装着部が縦挿入孔に縦方向に挿入されることにより、固定部材がハウジングに対して縦向き姿勢で装着される。また、ハウジング装着部が横挿入孔に横方向に挿入されることにより、固定部材がハウジングに対して横向き姿勢で装着される。このように、1つのハウジングに対する固定部材の装着姿勢を変更することにより、仕様変更に容易に対応することができる。また、固定部材の装着姿勢の変更時にハウジングを共用化できるため、コストが高くなるのを抑えることができる。さらに、縦挿入孔と横挿入孔とは互いに交差連通するため、固定部材受け部の大型化を回避することができる。   By inserting the housing mounting portion into the vertical insertion hole in the vertical direction, the fixing member is mounted in the vertical orientation with respect to the housing. In addition, the housing mounting portion is inserted in the lateral insertion hole in the lateral direction, so that the fixing member is mounted in a lateral orientation with respect to the housing. In this way, it is possible to easily cope with the specification change by changing the mounting posture of the fixing member with respect to one housing. Further, since the housing can be shared when the mounting posture of the fixing member is changed, it is possible to suppress an increase in cost. Furthermore, since the vertical insertion hole and the horizontal insertion hole communicate with each other, an increase in the size of the fixing member receiving portion can be avoided.

本発明の実施例1に係る基板用コネクタにおいて、端子金具が回路基板の板面に沿うように配置され、固定部材が横向き姿勢で配置された状態を示す側面図である。In the board connector according to the first embodiment of the present invention, the terminal fitting is arranged along the plate surface of the circuit board, and the fixing member is arranged in a sideways posture. 図1における固定部材受け部を破断した側面図である。It is the side view which fractured | ruptured the fixing member receiving part in FIG. 端子金具が回路基板の板面に沿うように配置され、固定部材が縦向き姿勢で配置された状態を示す側面図である。It is a side view which shows the state by which the terminal metal fitting is arrange | positioned along the board surface of a circuit board, and the fixing member is arrange | positioned in the vertical orientation. 図3における固定部材受け部を破断した側面図である。It is the side view which fractured | ruptured the fixing member receiving part in FIG. 固定部材受け部を破断したハウジングの側面図である。It is a side view of the housing which fractured | ruptured the fixing member receiving part. ハウジングの平面図である。It is a top view of a housing. 端子金具が回路基板を貫通して配置され、固定部材が縦向き姿勢で配置された状態を示す側面図である。It is a side view which shows the state by which the terminal metal fitting was arrange | positioned through the circuit board and the fixing member was arrange | positioned in the vertical orientation. 端子金具が回路基板を貫通して配置され、固定部材が横向き姿勢で配置された状態を示す側面図である。It is a side view which shows the state by which the terminal metal fitting was arrange | positioned through the circuit board and the fixing member was arrange | positioned in the horizontal attitude | position. 図8における固定部材受け部を破断した側面図である。It is the side view which fractured | ruptured the fixing member receiving part in FIG.

本発明の好ましい実施形態を以下に示す。
前記横挿入孔は、前記ハウジングに対して前記端子金具が装着される側となる後方に、前記ハウジング装着部の挿入口を有するとよい。これによれば、横挿入孔に対するハウジング装着部の挿入方向を、端子の装着方向と同じ方向に揃えることができるため、組み付け作業性が良好となる。
Preferred embodiments of the present invention are shown below.
The lateral insertion hole may have an insertion port for the housing mounting portion on the rear side of the housing on the side where the terminal fitting is mounted. According to this, since the insertion direction of the housing mounting part with respect to the horizontal insertion hole can be aligned in the same direction as the terminal mounting direction, the assembling workability is improved.

前記固定部材は、線状部材であって、前記ハウジング装着部が前記縦挿入孔に挿入された場合には前記基板固定部が前記回路基板の固定孔に差し込まれて半田固定され、前記ハウジング装着部が前記横挿入孔に挿入された場合には前記基板固定部の側面部分が前記回路基板の板面に沿って半田固定されるような形状になっているとよい。これによれば、固定部材の全体形状を簡単にすることができる。   The fixing member is a linear member, and when the housing mounting portion is inserted into the vertical insertion hole, the substrate fixing portion is inserted into the fixing hole of the circuit board and soldered, and the housing mounting When the portion is inserted into the lateral insertion hole, the side surface portion of the substrate fixing portion may be shaped to be soldered along the plate surface of the circuit board. According to this, the whole shape of the fixing member can be simplified.

<実施例1>
以下、実施例1を図1〜図9に基づいて説明する。本実施例1に係る基板用コネクタは、回路基板90に設置され、ハウジング10と、ハウジング10に装着される端子金具80A、80Bと、ハウジング10に装着され、且つ回路基板90に固定される固定部材60とを備えている。固定部材60はハウジング10に対する装着姿勢を変更可能とされる。また、ハウジング10は、回路基板90の設置された状態で、図示しない相手ハウジングと嵌合可能とされる。なお、以下の説明において、前後方向は、回路基板90の板面に沿う方向で且つ嵌合時に相手ハウジングを向く側を前側とし、上下方向は、回路基板90の板面と直交する方向で且つ回路基板90に対してハウジング10が位置する側を上側とする。
<Example 1>
Hereinafter, Example 1 is demonstrated based on FIGS. The board connector according to the first embodiment is installed on the circuit board 90, and is fixed to the housing 10, terminal fittings 80 </ b> A and 80 </ b> B attached to the housing 10, and attached to the housing 10 and fixed to the circuit board 90. And a member 60. The fixing member 60 can change the mounting posture with respect to the housing 10. Further, the housing 10 can be fitted with a mating housing (not shown) with the circuit board 90 installed. In the following description, the front-rear direction is a direction along the plate surface of the circuit board 90 and the side facing the mating housing when fitted is the front side, and the vertical direction is a direction orthogonal to the plate surface of the circuit board 90 and The side on which the housing 10 is located with respect to the circuit board 90 is the upper side.

ハウジング10は合成樹脂製であって、前方に開口するフード部11を有している。フード部11は、左右方向に長い扁平角筒状をなし、奥壁部分に、複数の端子金具80A、80Bが後方から圧入により装着される。フード部11の内部に相手ハウジングが嵌合されることにより、各端子金具80A、80Bが相手ハウジング内に配置された図示しない相手端子金具に電気的に接続されるようになっている。なお、本実施例1の場合、ハウジング10は、後述する表面実装型の端子金具80Aが装着されるものと、スルーホール型の端子金具80Bが装着されるものとで、サイズが異なる等の相違点を有するが(図1及び図7を参照)、上記基本構成が共通しており、特に区別する必要もないことから、同一符号を付して説明する。   The housing 10 is made of synthetic resin and has a hood portion 11 that opens forward. The hood portion 11 has a flat rectangular tube shape that is long in the left-right direction, and a plurality of terminal fittings 80A and 80B are attached to the back wall portion by press-fitting from the rear. By fitting the mating housing inside the hood portion 11, each terminal fitting 80A, 80B is electrically connected to a mating terminal fitting (not shown) disposed in the mating housing. In the case of the first embodiment, the housing 10 is different in size and the like between a housing 10 to which a surface mount type terminal fitting 80A described later is attached and a housing 10 to which a through hole type terminal fitting 80B is attached. Although there are points (see FIG. 1 and FIG. 7), the basic configuration is the same, and it is not necessary to distinguish between them.

端子金具80A、80Bは導電金属製の棒状部材であって、フード部11内に突出して相手端子金具に接続される部分を有し、且つ奥壁部分を貫通してフード部11より後方に露出状態で突出する部分を有している。端子金具80A、80Bは、後方への突出部分の形状を異にする2種類で構成され、いずれか1種が選択的にフード部11に装着される。2種類のうちの1種類の端子金具80Aは、図1に示すように、後方への突出する部分が長さ方向途中で2回折り曲げられ、下端部が回路基板90の表面(上側の板面)に沿って配置されて回路基板90の表面の導電部分に半田付けして接続される表面実装型である。また、他の1種類の端子金具80Bは、図7に示すように、後方への突出部分が長さ方向途中に1回折り曲げられ、下端部が回路基板90に設けられた接続孔91を貫通して接続孔91の導電部分に半田付けして接続されるスルーホール型である。   The terminal fittings 80A and 80B are bar members made of conductive metal, have a portion that protrudes into the hood portion 11 and is connected to the mating terminal fitting, and is exposed rearward from the hood portion 11 through the back wall portion. It has a part protruding in the state. The terminal fittings 80 </ b> A and 80 </ b> B are composed of two types having different shapes of the rearward protruding portions, and any one of them is selectively attached to the hood portion 11. As shown in FIG. 1, one type of terminal fitting 80A of the two types has a rearward protruding portion bent twice in the middle in the length direction, and a lower end portion of the surface of the circuit board 90 (upper plate surface). ) And is connected to the conductive portion on the surface of the circuit board 90 by soldering. Further, as shown in FIG. 7, the other one type of terminal fitting 80B has a rearward protruding portion bent once in the middle in the length direction and a lower end penetrating through a connection hole 91 provided in the circuit board 90. Then, it is a through-hole type that is connected to the conductive portion of the connection hole 91 by soldering.

フード部11の両側壁の外面には、図5及び図6に示すように、前後方向中央部より少し後方に、一対の固定部材受け部12が突出して設けられている。固定部材受け部12は、左右方向に扁平な角ブロック状をなし、図5に示すように、内部に、ほぼ上下方向に延出して上下両端に開口する互いにほぼ平行な一対の縦挿入孔13と、ほぼ前後方向に延出して前後両端に開口する1つの横挿入孔14とを有している。両縦挿入孔13及び横挿入孔14は、それぞれの延出方向途中でほぼ直角に互いに交差連通している。   As shown in FIGS. 5 and 6, a pair of fixing member receiving portions 12 are provided on the outer surfaces of both side walls of the hood portion 11 so as to protrude slightly behind the central portion in the front-rear direction. The fixing member receiving portion 12 has a rectangular block shape that is flat in the left-right direction. As shown in FIG. 5, the fixing member receiving portion 12 has a pair of substantially parallel vertical insertion holes 13 that extend substantially in the vertical direction and open at both the upper and lower ends. And one horizontal insertion hole 14 extending substantially in the front-rear direction and opening at both front-rear ends. Both the vertical insertion holes 13 and the horizontal insertion holes 14 cross and communicate with each other at substantially right angles in the middle of their extending directions.

両縦挿入孔13は、断面略矩形状であって、図5に示すように、固定部材受け部12の前後両側部にそれぞれ配置され、上端部の対向内縁に、後述する横溝17へ向けて傾斜状に拡幅する傾斜縁15を有している。横挿入孔14は、断面略矩形状であって、固定部材受け部12の上下方向略中央部に配置されている。固定部材受け部12の下端面は、横挿入孔14とほぼ平行に配置される平坦な固定部材沿面16とされている。固定部材沿面16とフード部11の底面との上下方向の離間距離は、固定部材60の後述する脚部62の上下方向の厚さよりも小さくされている。   Both vertical insertion holes 13 are substantially rectangular in cross section, and are respectively disposed on both front and rear side portions of the fixing member receiving portion 12 as shown in FIG. It has an inclined edge 15 that widens in an inclined manner. The lateral insertion hole 14 has a substantially rectangular cross section, and is disposed at a substantially central portion in the vertical direction of the fixing member receiving portion 12. The lower end surface of the fixing member receiving portion 12 is a flat fixing member creeping surface 16 disposed substantially parallel to the lateral insertion hole 14. The vertical separation distance between the fixing member creeping surface 16 and the bottom surface of the hood portion 11 is set to be smaller than the vertical thickness of a leg portion 62 described later of the fixing member 60.

また、図5に示すように、固定部材受け部12は、上端面に開口しつつ前後方向に延出し、両縦挿入孔13の上端と連通する横溝17と、後端面の略下半部に開口しつつ上下方向に延出し、横挿入孔14の後端と連通する縦溝18とを有している。横溝17と連通する両縦挿入孔13の上端と、縦溝18と連通する横挿入孔14の後端は、固定部材60の後述するハウジング装着部64の挿入口19、21として構成される。横溝17の前後両縁は、上方へ向けてテーパ状に拡開するテーパ縁22となっている。縦溝18の下端は、固定部材受け部12の下端面に開口し、固定部材沿面16と交差している。   Further, as shown in FIG. 5, the fixing member receiving portion 12 extends in the front-rear direction while opening at the upper end surface, and communicates with the lateral groove 17 communicating with the upper ends of the vertical insertion holes 13 and the substantially lower half of the rear end surface. While opening, it has a vertical groove 18 extending in the vertical direction and communicating with the rear end of the horizontal insertion hole 14. The upper ends of both vertical insertion holes 13 communicating with the horizontal grooves 17 and the rear ends of the horizontal insertion holes 14 communicating with the vertical grooves 18 are configured as insertion ports 19 and 21 of a housing mounting portion 64 described later of the fixing member 60. Both front and rear edges of the lateral groove 17 are tapered edges 22 that expand upward in a tapered shape. The lower end of the vertical groove 18 opens to the lower end surface of the fixing member receiving portion 12 and intersects the fixing member creeping surface 16.

続いて、固定部材60について説明する。固定部材60は、金属製の線状部材であって、断面略矩形状をなしている。具体的には、固定部材60は、長尺の線材をU字状(門型状)に屈曲してなるものであって、図2及び図4に示すように、連結部61と、連結部61の両端から互いにほぼ平行に突出する一対の脚部62とからなる。両脚部62は、縦挿入孔13及び横挿入孔14のそれぞれの延出長さを越える長さで構成されている。両脚部62の先端は、テーパ状に窄み形成されている。   Next, the fixing member 60 will be described. The fixing member 60 is a metal linear member and has a substantially rectangular cross section. Specifically, the fixing member 60 is formed by bending a long wire rod into a U shape (gate shape). As shown in FIGS. 2 and 4, the fixing member 60 includes a connecting portion 61 and a connecting portion. It consists of a pair of leg parts 62 projecting substantially parallel to each other from both ends of 61. Both leg portions 62 are configured to have a length exceeding the extension length of each of the vertical insertion hole 13 and the horizontal insertion hole 14. The tips of both leg portions 62 are tapered and formed.

図2及び図4に示すように、両脚部62のうちの一方又は両方には、連結部61寄りの位置に、係止部63が設けられている。係止部63は、詳細は図示しないが、脚部62の四角部を圧潰することによって周方向に複数のエッジを突出させてなるものである。   As shown in FIGS. 2 and 4, one or both of the leg portions 62 is provided with a locking portion 63 at a position near the connecting portion 61. Although not shown in detail, the locking part 63 is formed by projecting a plurality of edges in the circumferential direction by crushing the square part of the leg part 62.

脚部62は、固定部材受け部12に装着されるハウジング装着部64と、回路基板90に固定される基板固定部65とを有している。係止部63は、ハウジング装着部64に設けられている。ハウジング装着部64は、固定部材受け部12の縦挿入孔13と横挿入孔14のいずれかに選択的に挿入される。基板固定部65は、ハウジング装着部64が縦挿入孔13に挿入される場合と横挿入孔14に挿入される場合とで、回路基板90に対する固定部位を異ならせる。この点については後述する。   The leg portion 62 includes a housing mounting portion 64 that is mounted on the fixing member receiving portion 12 and a substrate fixing portion 65 that is fixed to the circuit board 90. The locking part 63 is provided on the housing mounting part 64. The housing mounting portion 64 is selectively inserted into either the vertical insertion hole 13 or the horizontal insertion hole 14 of the fixing member receiving portion 12. The board fixing portion 65 makes the fixing portion for the circuit board 90 different depending on whether the housing mounting portion 64 is inserted into the vertical insertion hole 13 or the horizontal insertion hole 14. This point will be described later.

製造に際し、図示しない長尺の線材にめっき処理を施した後、切断して折り曲げ、又は折り曲げて切断し、さらに、係止部63を圧潰形成して、複数の固定部材60を成形する。これにより、固定部材60の側面部分(外周面部分)は、めっき面となり、固定部材60の先端面は、非めっき面(破断面)となる。   In manufacturing, a long wire (not shown) is plated, and then cut and bent, or bent and cut, and further, the locking portions 63 are crushed to form a plurality of fixing members 60. Thereby, the side surface part (outer peripheral surface part) of the fixing member 60 becomes a plating surface, and the front end surface of the fixing member 60 becomes a non-plating surface (fracture surface).

続いて、本実施例1の作用効果を説明する。
本実施例1の基板用コネクタは、表面実装型の端子金具80Aがハウジング10に装着され、且つ固定部材60のハウジング装着部64が固定部材受け部12の横挿入孔14に挿入される第1態様(図1及び図2を参照)と、表面実装型の端子金具80Aがハウジング10に装着され、且つ固定部材60のハウジング装着部64が固定部材受け部12の縦挿入孔13に挿入される第2態様(図3及び図4を参照)と、スルーホール型の端子金具80Bがハウジング10に装着され、且つ固定部材60のハウジング装着部64が固定部材受け部12の縦挿入孔13に挿入される第3態様(図7を参照)と、スルーホール型の端子金具80Bがハウジング10に装着され、且つ固定部材60のハウジング装着部64が固定部材受け部12の横挿入孔14に挿入される第4態様(図8及び図9を参照)のうちのいずれかの態様を選択的にとり得る。
Then, the effect of the present Example 1 is demonstrated.
In the board connector according to the first embodiment, the surface mounting type terminal fitting 80A is mounted on the housing 10, and the housing mounting portion 64 of the fixing member 60 is inserted into the lateral insertion hole 14 of the fixing member receiving portion 12. The embodiment (see FIGS. 1 and 2), the surface mounting type terminal fitting 80A is mounted on the housing 10, and the housing mounting portion 64 of the fixing member 60 is inserted into the vertical insertion hole 13 of the fixing member receiving portion 12. In the second mode (see FIGS. 3 and 4), the through-hole type terminal fitting 80B is mounted on the housing 10, and the housing mounting portion 64 of the fixing member 60 is inserted into the vertical insertion hole 13 of the fixing member receiving portion 12. And the through hole type terminal fitting 80B is mounted on the housing 10, and the housing mounting portion 64 of the fixing member 60 is inserted laterally into the fixing member receiving portion 12. May selectively to take one of the embodiments of the fourth aspect (see FIGS. 8 and 9) inserted 14.

図1及ぶ図2に示す第1態様では、固定部材60が前後方向にほぼ沿った横向きの姿勢をとって固定部材受け部12に後方から挿入される。図2に示すように、連結部61が縦溝18に挿入され、両脚部62のうち、上側の脚部62が挿入口21から横挿入孔14を略水平に圧入状態で貫通するとともに、下側の脚部62における側面部分の上側面が固定部材沿面16に沿って配置され、且つ、両脚部62の先端部が固定部材受け部12よりも前方に突出して配置される。係止部63は、上側の脚部62にのみ設けられ、固定部材受け部12の内壁に食い込み係止される。これにより、固定部材60が固定部材受け部12に抜け止め状態に保持される。上側の脚部62のうち、固定部材受け部12の内部に挿入される部分がハウジング装着部64となるものである。   In the first mode shown in FIG. 1 and FIG. 2, the fixing member 60 is inserted into the fixing member receiving portion 12 from the rear in a lateral orientation substantially along the front-rear direction. As shown in FIG. 2, the connecting portion 61 is inserted into the longitudinal groove 18, and the upper leg portion 62 of both the leg portions 62 penetrates the horizontal insertion hole 14 from the insertion port 21 in a substantially horizontal press-fit state, and The upper side surface of the side surface portion of the leg portion 62 on the side is disposed along the fixing member creeping surface 16, and the distal end portions of both leg portions 62 are disposed so as to protrude forward from the fixing member receiving portion 12. The locking portion 63 is provided only on the upper leg portion 62 and is engaged with and locked to the inner wall of the fixing member receiving portion 12. As a result, the fixing member 60 is held by the fixing member receiving portion 12 in a retaining state. Of the upper leg portion 62, the portion inserted into the fixed member receiving portion 12 serves as the housing mounting portion 64.

回路基板90への実装時、回路基板90の表面には、下側の脚部62における側面部分の下側面が前後方向に沿って配置され、リフロー半田により下側の脚部62の側面部分に半田が付着して固定される。この場合、下側の脚部62には、固定部材沿面16に沿う部分を除いて、半田が付着する面が広範に確保されており、さらに、下側の脚部62の側面部分はめっき面であるため、半田濡れ性を良好にすることができる。なお、下側の脚部62の側面部分が基板固定部65となるものである。
各端子金具80Aは下端部が回路基板90の表面に前後方向に沿って配置され、上記リフロー半田時に回路基板90の導電部分に半田接続される。
When mounted on the circuit board 90, the lower surface of the side surface portion of the lower leg portion 62 is disposed along the front-rear direction on the surface of the circuit board 90, and the side surface portion of the lower leg portion 62 is formed by reflow soldering. Solder adheres and is fixed. In this case, the lower leg portion 62 has a wide surface to which the solder adheres except for the portion along the fixing member creeping surface 16, and the side portion of the lower leg portion 62 is a plated surface. Therefore, solder wettability can be improved. The side surface portion of the lower leg portion 62 becomes the substrate fixing portion 65.
Each terminal fitting 80A has a lower end portion disposed on the surface of the circuit board 90 along the front-rear direction, and is solder-connected to the conductive portion of the circuit board 90 during the reflow soldering.

図3及び図4に示す第2態様は、固定部材60が上下方向にほぼ沿った縦向きの姿勢をとって固定部材受け部12に上方から挿入される。図4に示すように、連結部61が横溝17に挿入され、両脚部62が挿入口19から縦挿入孔13を略垂直に圧入状態で貫通するとともに、両脚部62の先端部が固定部材60よりも下方に突出して配置される。このとき、両脚部62の先端は、テーパ縁22と傾斜縁15とにより縦挿入孔13に誘い込まれる。係止部63は、両脚部62に設けられ、固定部材受け部12の内壁に食い込み係止される。両脚部62のうち、固定部材受け部12の内部に挿入される部分がハウジング装着部64となるものである。   In the second mode shown in FIGS. 3 and 4, the fixing member 60 is inserted into the fixing member receiving portion 12 from above in a vertical orientation substantially along the vertical direction. As shown in FIG. 4, the connecting portion 61 is inserted into the lateral groove 17, the both leg portions 62 penetrate the vertical insertion hole 13 from the insertion port 19 in a substantially vertical press-fit state, and the distal end portions of both leg portions 62 are fixed members 60. It protrudes below and is arranged. At this time, the tips of both leg portions 62 are drawn into the vertical insertion hole 13 by the tapered edge 22 and the inclined edge 15. The locking part 63 is provided on the both leg parts 62 and is engaged with and locked to the inner wall of the fixing member receiving part 12. Of the both leg portions 62, the portion inserted into the fixing member receiving portion 12 is the housing mounting portion 64.

ハウジング10が回路基板90の表面に設置されるに伴い、両脚部62の先端部が回路基板90に設けられた固定孔92に上方から差し込まれ、両脚部62の先端部の側面部分に半田が施されて固定される。表面実装型の場合と同様、両脚部62の側面部分はめっき面であるため、半田濡れ性を良好にすることができる。端子金具80Aについては第1態様と同様である。   As the housing 10 is installed on the surface of the circuit board 90, the tip ends of both leg portions 62 are inserted from above into the fixing holes 92 provided in the circuit board 90, and solder is applied to the side portions of the tip portions of the both leg portions 62. Applied and fixed. As in the case of the surface mount type, since the side surfaces of both the leg portions 62 are plated surfaces, the solder wettability can be improved. The terminal fitting 80A is the same as in the first mode.

図7に示す第3態様は、固定部材60が上下方向にほぼ沿った縦向きの姿勢をとって固定部材受け部12に上方から挿入される。よって、固定部材60については第2態様と同様である。一方、端子金具80Bはスルーホール型であるため、ハウジング10が回路基板90の表面に設置されるに伴い、端子金具80Bの下端部が回路基板90に設けられた接続孔91に上方から差し込まれ、導電部分に半田接続される。   In the third mode shown in FIG. 7, the fixing member 60 is inserted into the fixing member receiving portion 12 from above in a vertical orientation substantially along the vertical direction. Therefore, the fixing member 60 is the same as in the second mode. On the other hand, since the terminal fitting 80B is a through-hole type, the lower end portion of the terminal fitting 80B is inserted into the connection hole 91 provided in the circuit board 90 from above as the housing 10 is installed on the surface of the circuit board 90. The solder is connected to the conductive portion.

図8及び図9に示す第4態様は、固定部材60が前後方向にほぼ沿った横向きの姿勢をとって固定部材受け部12に後方から挿入される。よって、固定部材60については第1態様と同様であり、端子金具80Bについては第3態様と同様である。   In the fourth mode shown in FIGS. 8 and 9, the fixing member 60 is inserted into the fixing member receiving portion 12 from the rear side in a lateral orientation substantially along the front-rear direction. Therefore, the fixing member 60 is the same as the first aspect, and the terminal fitting 80B is the same as the third aspect.

以上説明したように、本実施例1によれば、ハウジング装着部64が縦挿入孔13に挿入されることにより、固定部材60がハウジング10に対して縦向き姿勢の第2、第3態様をとることができるとともに、ハウジング装着部64が横挿入孔14に挿入されることにより、固定部材60がハウジング10に対して横向き姿勢の第1、第4態様をとることができる。このように、1つのハウジング10に対する固定部材60の装着姿勢を変更することにより、仕様変更の要請に容易且つ迅速に対応することができる。また、かかる固定部材60の姿勢変更時にハウジング10が共用化されるため、コストの上昇を抑えることができる。さらに、縦挿入孔13と横挿入孔14とが互いに交差連通するため、固定部材受け部12が左右方向に大きくなることがなく、コネクタの大型化を招来することがない。しかも、固定部材60はU字状の線状部材であるから、その全体形状が特別複雑になることもない。   As described above, according to the first embodiment, when the housing mounting portion 64 is inserted into the vertical insertion hole 13, the fixing member 60 has the second and third modes in the vertical orientation with respect to the housing 10. In addition, the housing mounting portion 64 is inserted into the lateral insertion hole 14, whereby the fixing member 60 can take the first and fourth modes in the lateral orientation with respect to the housing 10. Thus, by changing the mounting posture of the fixing member 60 with respect to one housing 10, it is possible to easily and quickly respond to a request for a specification change. Further, since the housing 10 is shared when the posture of the fixing member 60 is changed, an increase in cost can be suppressed. Furthermore, since the vertical insertion hole 13 and the horizontal insertion hole 14 are in cross communication with each other, the fixing member receiving portion 12 does not increase in the left-right direction, and the size of the connector does not increase. Moreover, since the fixing member 60 is a U-shaped linear member, the overall shape thereof is not particularly complicated.

さらにまた、横挿入孔14がハウジング10に対して端子金具80A、80Bが装着される側となる後方に、ハウジング装着部64の挿入口21を有するため、横挿入孔14に対するハウジング装着部64の挿入方向を、端子金具80A、80Bの装着方向と同じ向きに揃えることができるため、組み付け作業性が良好となる。   Furthermore, since the side insertion hole 14 has the insertion port 21 of the housing mounting portion 64 on the rear side where the terminal fittings 80A and 80B are mounted on the housing 10, the housing mounting portion 64 with respect to the side insertion hole 14 is provided. Since the insertion direction can be aligned in the same direction as the mounting direction of the terminal fittings 80A and 80B, assembly workability is improved.
