Description

本発明は、自動車等に配索されるワイヤハーネスに用いられるコネクタに関するものである。 The present invention relates to a connector used for a wire harness distributed in an automobile or the like.

従来から、ワイヤハーネスの端末に取り付けられるコネクタは、ワイヤハーネスを構成する複数の電線端末にそれぞれ設けられた複数の接続端子と、かかる複数の接続端子をそれぞれ収容保持する複数の端子収容室を有するコネクタハウジングを備えている。ところで、コネクタハウジングの端子収容室は四方を周壁部に囲われた筒形状とされていることから、コネクタの製造時には、電線端末に設けられた複数の接続端子を１本ずつ端子収容室に挿入する作業が必要となることから、作業性の悪化を招いていた。 Conventionally, a connector attached to a terminal of a wire harness has a plurality of connection terminals provided on each of a plurality of electric wire terminals constituting the wire harness, and a plurality of terminal accommodating chambers for accommodating and holding the plurality of connection terminals. It has a connector housing. By the way, since the terminal accommodating chamber of the connector housing has a tubular shape surrounded by peripheral walls on all sides, a plurality of connection terminals provided on the electric wire terminal are inserted into the terminal accommodating chamber one by one at the time of manufacturing the connector. Since the work to be done is required, the workability is deteriorated.

これに対して、例えば、特開２００１−２３００３８号公報（特許文献１）に開示されているように、溝状の端子収容室を複数併設したプレート状のハウジングを採用して、ハウジングの上面に開口した複数の溝状の端子収容室に対して、上方から複数の接続端子を挿し入れる作業を行うことにより作業性の向上を図った構造が提案されている。 On the other hand, for example, as disclosed in Japanese Patent Application Laid-Open No. 2001-230038 (Patent Document 1), a plate-shaped housing provided with a plurality of groove-shaped terminal accommodating chambers is adopted, and the upper surface of the housing is covered with a plate-shaped housing. A structure has been proposed in which workability is improved by inserting a plurality of connection terminals from above into a plurality of open groove-shaped terminal accommodating chambers.

ところが、このような溝状の端子収容室を採用した場合には、端子収容室の上面が開口していることから、組み付け作業時や使用時において、端子収容室の後端開口部から延び出す電線へ応力が集中し易く、極細線等のように電線の強度自体が弱い場合には、電線の強度を担保し難くなって、溝状の端子収容室を採用すること自体が難しくなる場合があった。 However, when such a groove-shaped terminal accommodating chamber is adopted, since the upper surface of the terminal accommodating chamber is open, it extends from the rear end opening of the terminal accommodating chamber during assembly work or use. When stress tends to concentrate on the wire and the strength of the wire itself is weak, such as an ultra-fine wire, it may be difficult to secure the strength of the wire, and it may be difficult to adopt a groove-shaped terminal accommodating chamber. there were.

More specifically, the insulating coating 72 on the tip side (right side in FIG. 8) of the electric wire 12 is peeled off to expose the core wire 74, the core wire 74 is exposed to the core wire crimping portion 76 of the connection terminal 70, and the core wire 74 is exposed. By crimping the tip portion of the electric wire 12 to the electric wire crimping portion 78 of the connection terminal 70, the electric wire 12 is fixed and connected to the connection terminal 70. Further, a cylindrical connecting portion 80 that opens in the length direction (left-right direction in FIG. 8) is formed at the tip end portion (right side in FIG. 8) of the connection terminal 70. Then, as shown in FIG. 8, the connection terminal 70 has a recess 82 that opens in the surface of the terminal accommodating chamber 26 facing the bottom surface 28 between the core wire crimping portion 76 and the connection portion 80. Is provided. In addition, on the outer surface of the connecting portion 80, an engaging portion 83 extending along the outer surface is formed at the rear end portion (left end portion in FIG. 8) of the lower portion in FIG. 8, while the lower portion in FIG. At the front end portion (right end portion in FIG. 8), an engaging portion 84 extending diagonally outward and rearward is formed. Further, on the inner surface of the connecting portion 80, an elastic contact piece 86 extending along the inner surface from the rear end portion (left end portion in FIG. 8) at the upper part in FIG. 8 and extending inward diagonally forward is formed. There is. Further, an embossed portion 88 is formed on the inner surface of the connecting portion 80 by projecting the lower front end side (right end side in FIG. 8) inward in FIG. By sandwiching the mating terminal 89 between the elastic contact piece 86 and the embossed portion 88, the mating terminal 89 is connected to the mating connector. In FIG. 8, the counterpart terminal 89 is shown by a virtual line for easy understanding. Further, as shown in FIG. 2, a plurality of electric wires 12 extending from the connection terminal 70 are fixed to the sheet-shaped reinforcing member 90 in a state of being arranged in parallel. Positioning holes 92 having a substantially circular cross-sectional shape are formed on both sides in the width direction of the sheet-shaped reinforcing member 90 on both sides of the plurality of electric wires 12 on the front end side (right end side in FIG. 7).

なお、電線１２は、導体である銅やアルミニウムその他の金属線の複数を束ね合わせた芯線７４が、エチレン系樹脂やスチレン系樹脂等の電気絶縁性を有する絶縁被覆７２で覆われた構造とされている。一方、接続端子７０は、導電性を有しかつプレス加工や打抜き加工等が可能な種々の金属材料、例えば真鍮や銅、銅合金、アルミニウム、アルミニウム合金等を用いて一体的に形成されている。さらに、シート状補強部材９０として、例えばガラス繊維不織布やアラミド繊維不織布等に対してエポキシ樹脂やフェノール樹脂等を含浸させたものを用いて、ヒートプレス等でシート状補強部材９０を電線１２に押し付けることにより固着することが可能となっている。 The electric wire 12 has a structure in which a core wire 74 obtained by bundling a plurality of conductors such as copper, aluminum, and other metal wires is covered with an insulating coating 72 having electrical insulation properties such as ethylene resin and styrene resin. ing. On the other hand, the connection terminal 70 is integrally formed by using various metal materials having conductivity and capable of press working, punching, etc., for example, brass, copper, copper alloy, aluminum, aluminum alloy and the like. .. Further, as the sheet-shaped reinforcing member 90, for example, a glass fiber non-woven fabric, an aramid fiber non-woven fabric, or the like impregnated with an epoxy resin, a phenol resin, or the like is used, and the sheet-shaped reinforcing member 90 is pressed against the electric wire 12 by heat pressing or the like. This makes it possible to fix the fibers.

このような構成とされたコネクタ１０が、以下のようにして組み立てられる。まず、端末に接続端子７０が接続されている複数の電線１２がそれぞれ並列配置された状態でシート状補強部材９０に対して固着されているシート状補強部材付電線束９４を準備する。そして、かかるシート状補強部材付電線束９４における複数の電線１２の端末に設けられた複数の接続端子７０を、ハウジング本体１６に設けられた端子収容室２６にそれぞれ収容配置すると共に、シート状補強部材９０に貫設されている位置決め穴９２をハウジング本体１６の位置決め突起５６に嵌め入れる。この結果、端子収容室２６の後端側開口部５０から延び出す複数の電線１２が、電線支持部２２に設けられた電線収容溝５４に収容保持されると共に、シート状補強部材９０の前端部側（図７中、右端側）がハウジング本体１６の上面２４に載置される。より詳細には、接続端子７０を上方から端子収容室２６に対して一対の係合突起３０，３０が凹所８２に配置されるように挿入する。これにより、前方側（図８中、右側）に位置する係合爪３２を有する係合突起３０からなる弾性ロック爪３４が後方側に弾性変形されて接続端子７０の端子収容室２６への挿入を許容する。続いて、接続端子７０が端子収容室２６に載置された際には弾性ロック爪３４が弾性復帰して弾性ロック爪３４の係合爪３２が接続端子７０の接続部８０の内面に入り込んで係合することにより、接続端子７０が端子収容室２６から上方に抜け出すことが有利に阻止されている（図８参照）。この結果、一対の係合突起３０，３０が接続端子７０の凹所８２に挿入配置されて長手方向（図８中、左右方向）の両側で一対の係合突起３０，３０と凹所８２の形成面である芯線加締め部７６の前端部と接続部８０の後端部がそれぞれ当接することにより、長手方向両側で接続端子７０が端子収容室２６に対して位置決め保持されている。加えて、端子収容室２６の長手方向の先端側（図８中、右側）には、相手側端子８９が挿入される接続端子７０の筒状の接続部８０が配設されている。上述のように、弾性ロック爪３４が弾性復帰して弾性ロック爪３４の係合爪３２が接続端子７０の接続部８０の内面に入り込んで係合するようになっていることから、弾性ロック爪３４の接続部８０の内面への入り込み量が相手側端子８９に干渉しない範囲に設定されている。 The connector 10 having such a configuration is assembled as follows. First, a wire bundle 94 with a sheet-shaped reinforcing member is prepared, in which a plurality of electric wires 12 to which the connecting terminals 70 are connected to the terminal are arranged in parallel, respectively, and fixed to the sheet-shaped reinforcing member 90. Then, the plurality of connection terminals 70 provided at the terminals of the plurality of electric wires 12 in the electric wire bundle 94 with the sheet-shaped reinforcing member are accommodated and arranged in the terminal accommodating chamber 26 provided in the housing main body 16, and the sheet-shaped reinforcing member is reinforced. The positioning hole 92 penetrating the member 90 is fitted into the positioning protrusion 56 of the housing body 16. As a result, a plurality of electric wires 12 extending from the rear end side opening 50 of the terminal accommodating chamber 26 are accommodated and held in the electric wire accommodating groove 54 provided in the electric wire support portion 22, and the front end portion of the sheet-shaped reinforcing member 90 is accommodated and held. The side (right end side in FIG. 7) is placed on the upper surface 24 of the housing body 16. More specifically, the connection terminal 70 is inserted from above so that the pair of engaging projections 30 and 30 are arranged in the recess 82 with respect to the terminal accommodating chamber 26. As a result, the elastic lock claw 34 composed of the engaging protrusion 30 having the engaging claw 32 located on the front side (right side in FIG. 8) is elastically deformed to the rear side and the connection terminal 70 is inserted into the terminal accommodating chamber 26. Tolerate. Subsequently, when the connection terminal 70 is placed in the terminal accommodating chamber 26, the elastic lock claw 34 elastically returns, and the engagement claw 32 of the elastic lock claw 34 enters the inner surface of the connection portion 80 of the connection terminal 70. By engaging, the connection terminal 70 is advantageously prevented from coming out of the terminal accommodating chamber 26 upward (see FIG. 8). As a result, the pair of engaging protrusions 30, 30 are inserted and arranged in the recesses 82 of the connection terminal 70, and the pair of engaging protrusions 30, 30 and the recesses 82 are arranged on both sides in the longitudinal direction (left-right direction in FIG. 8). The connection terminals 70 are positioned and held with respect to the terminal accommodating chamber 26 on both sides in the longitudinal direction by abutting the front end portion of the core wire crimping portion 76, which is the forming surface, and the rear end portion of the connecting portion 80, respectively. In addition, on the distal end side (right side in FIG. 8) of the terminal accommodating chamber 26 in the longitudinal direction, a tubular connecting portion 80 of the connecting terminal 70 into which the mating terminal 89 is inserted is arranged. As described above, the elastic lock claw 34 is elastically restored so that the engagement claw 32 of the elastic lock claw 34 enters the inner surface of the connection portion 80 of the connection terminal 70 and engages with the elastic lock claw 34. The amount of penetration of the connecting portion 80 of 34 into the inner surface is set within a range that does not interfere with the mating terminal 89.

最後に、カバー部１８を上方からハウジング本体１６の上面２４に重ね合わせて、ハウジング本体１６に設けられた位置決め突起５６をカバー部１８の貫通孔６８に対して圧入する。この結果、カバー部１８によってハウジング本体１６の端子収容室２６が蓋覆されると共に、シート状補強部材付電線束９４のシート状補強部材９０の前端部がハウジング本体１６の電線支持部２２とカバー部１８の挟持部６６の間で挟持されるようになっている。ここで、ハウジング本体１６の位置決め突起５６が嵌め入れられる第一位置決め凹部が、カバー部１８の貫通孔６８によりカバー部１８の下面に開口形成されている。さらに、カバー部１８の側壁６０に設けられたロック機構を構成する係合枠体６２の貫通孔６１に対して、ハウジング本体１６の側壁４２に設けられたロック機構を構成するロック部４６が係合されている。すなわち、カバー部１８とハウジング本体１６がそれぞれの側壁６０，４２に設けられたロック機構６２，４６によって相互にロック嵌合されているのである。加えて、カバー部１８の側壁６０に設けられた係合枠体６２の嵌合凹部６４に対してハウジング本体１６の側壁４２に設けられた嵌合突起４４が嵌め込まれている。以上のことにより、カバー部１８とハウジング本体１６の重ね合わせ状態を安定して保持することができると共に、シート状補強部材９０をハウジング本体１６の電線支持部２２とカバー部１８の挟持部６６との間で一層安定して挟持することが可能となっている。 Finally, the cover portion 18 is superposed on the upper surface 24 of the housing body 16 from above, and the positioning protrusion 56 provided on the housing body 16 is press-fitted into the through hole 68 of the cover portion 18. As a result, the terminal accommodating chamber 26 of the housing body 16 is covered by the cover portion 18, and the front end portion of the sheet-shaped reinforcing member 90 of the wire bundle 94 with the sheet-shaped reinforcing member covers the wire support portion 22 of the housing body 16. It is designed to be sandwiched between the sandwiching portions 66 of the portions 18. Here, a first positioning recess into which the positioning protrusion 56 of the housing body 16 is fitted is formed as an opening on the lower surface of the cover portion 18 by the through hole 68 of the cover portion 18. Further, the lock portion 46 constituting the lock mechanism provided on the side wall 42 of the housing body 16 is engaged with the through hole 61 of the engaging frame body 62 forming the lock mechanism provided on the side wall 60 of the cover portion 18. It is matched. That is, the cover portion 18 and the housing main body 16 are locked and fitted to each other by the locking mechanisms 62 and 46 provided on the side walls 60 and 42, respectively. In addition, the fitting projection 44 provided on the side wall 42 of the housing body 16 is fitted into the fitting recess 64 of the engaging frame 62 provided on the side wall 60 of the cover portion 18. As described above, the overlapped state of the cover portion 18 and the housing main body 16 can be stably held, and the sheet-shaped reinforcing member 90 can be held between the electric wire support portion 22 of the housing main body 16 and the holding portion 66 of the cover portion 18. It is possible to hold it more stably between them.

このような構造とされたコネクタ１０によれば、端子収容室２６がハウジング本体１６の上面２４に開口する溝形状とされていることから、シート状補強部材付電線束９４の複数の電線１２の端末に設けられた接続端子７０を複数の端子収容室２６に対して一括して上方から嵌め入れることが可能となっている。それゆえ、従来の如き四方を周壁に囲まれた筒形状の端子収容室に１本ずつ接続端子を収容する場合に比して、飛躍的な作業性の向上を図ることができる。さらに、ハウジング本体１６の端子収容部２０の端子収容室２６から延び出す電線１２に対する応力の集中も、端子収容室２６の後端側開口部５０に連接する溝状の電線収容溝５４によって電線１２が収容保持されていることにより低減されている。加えて、接続端子７０から延び出す複数の電線１２がそれぞれ並列配置された状態でシート状補強部材９０に対して固着されると共に、シート状補強部材９０の前端部がカバー部１８の挟持部６６とハウジング本体１６の電線支持部２２との間で挟持されている。これにより、複数の電線１２に対して外力が加わることが確実に回避乃至は低減されており、かかる部位の電線１２の強度担保を確実に実現することができる。それゆえ、電線１２として例えば極細線を採用する場合であっても、かかる溝形状の端子収容室２６を採用することが可能となっている。 According to the connector 10 having such a structure, since the terminal accommodating chamber 26 has a groove shape that opens in the upper surface 24 of the housing main body 16, the plurality of electric wires 12 of the electric wire bundle 94 with the sheet-shaped reinforcing member The connection terminals 70 provided on the terminals can be collectively fitted into the plurality of terminal accommodating chambers 26 from above. Therefore, the workability can be dramatically improved as compared with the conventional case where the connection terminals are housed one by one in the tubular terminal storage chamber surrounded by the peripheral walls on all sides. Further, stress concentration on the electric wire 12 extending from the terminal accommodating chamber 26 of the terminal accommodating portion 20 of the housing body 16 is also caused by the groove-shaped electric wire accommodating groove 54 connected to the rear end side opening 50 of the terminal accommodating chamber 26. Is reduced by being housed and held. In addition, a plurality of electric wires 12 extending from the connection terminal 70 are fixed to the sheet-shaped reinforcing member 90 in a state where they are arranged in parallel, and the front end portion of the sheet-shaped reinforcing member 90 is a holding portion 66 of the cover portion 18. It is sandwiched between the wire support portion 22 of the housing body 16 and the electric wire support portion 22 of the housing body 16. As a result, the application of an external force to the plurality of electric wires 12 is surely avoided or reduced, and the strength of the electric wires 12 at such a portion can be surely guaranteed. Therefore, even when an ultrafine wire is used as the electric wire 12, it is possible to use the groove-shaped terminal accommodating chamber 26.

また、ハウジング本体１６とシート状補強部材９０とカバー部１８との間の位置決めを、ハウジング本体１６の位置決め突起５６とシート状補強部材９０の位置決め穴９２とカバー部１８の貫通孔６８の協働により、確実に行うことができる。それゆえ、シート状補強部材９０がハウジング本体１６とカバー部１８との間の所定位置に安定して保持されて、一層確実に電線１２の強度を確保することができる。特に、電線支持部２２の上面４８に突設された位置決め突起５６にシート状補強部材９０の位置決め穴９２を嵌め入れて係止できることから、カバー部１８を装着する前にシート状補強部材９０をハウジング本体１６の電線支持部２２に安定して保持でき、作業性の向上を図ることができる。 Further, the positioning between the housing body 16, the sheet-shaped reinforcing member 90, and the cover portion 18 is coordinated by the positioning protrusion 56 of the housing body 16, the positioning hole 92 of the sheet-shaped reinforcing member 90, and the through hole 68 of the cover portion 18. Therefore, it can be surely performed. Therefore, the sheet-shaped reinforcing member 90 is stably held at a predetermined position between the housing body 16 and the cover portion 18, and the strength of the electric wire 12 can be secured more reliably. In particular, since the positioning hole 92 of the sheet-shaped reinforcing member 90 can be fitted and locked in the positioning protrusion 56 projecting from the upper surface 48 of the electric wire supporting portion 22, the sheet-shaped reinforcing member 90 is placed before the cover portion 18 is attached. It can be stably held by the electric wire support portion 22 of the housing body 16, and workability can be improved.

以上、本発明の実施形態について詳述したが、本発明はこれらの具体的な記載によって限定されない。例えば、上記第一の実施形態では、ハウジング本体１６は１段のみであったが、図９〜１０に示す本発明の第二の実施形態としてのコネクタ９６のように、ハウジング本体９８，１６が上下に積層されて構成されていてもよい。より詳細には、図９〜１０に示されているように、ハウジング本体９８，１６が上下２段に積層されており、下側のハウジング本体１６に重ね合される上側のハウジング本体９８の下面が、下側のハウジング本体１６の上面２４に重ね合されてハウジング本体１６の端子収容室２６が蓋覆されている。さらに、ハウジング本体９８によって、シート状補強部材９０をハウジング本体１６の電線支持部２２との間で挟持する中間カバー部が構成されている一方、かかる中間カバー部には、下側のハウジング本体１６における電線支持部２２に突設された位置決め突起５６が嵌め入れられる第二位置決め凹部１００が設けられている（図１０参照）。そして、第二位置決め凹部１００への位置決め突起５６の圧入により、上下に積層されたハウジング本体９８，１６同士が位置決め固定されるようになっている。 Although the embodiments of the present invention have been described in detail above, the present invention is not limited by these specific descriptions. For example, in the first embodiment, the housing body 16 has only one stage, but as in the connector 96 as the second embodiment of the present invention shown in FIGS. 9 to 10, the housing bodies 98 and 16 are used. It may be configured by being stacked on top of each other. More specifically, as shown in FIGS. 9 to 10, the housing bodies 98 and 16 are stacked in two upper and lower stages, and the lower surface of the upper housing body 98 is overlapped with the lower housing body 16. However, the terminal accommodating chamber 26 of the housing body 16 is covered with the upper surface 24 of the housing body 16 on the lower side. Further, the housing main body 98 constitutes an intermediate cover portion for sandwiching the sheet-shaped reinforcing member 90 with the electric wire support portion 22 of the housing main body 16, while the intermediate cover portion includes the lower housing main body 16. A second positioning recess 100 into which the positioning protrusion 56 projecting from the electric wire support portion 22 is fitted is provided (see FIG. 10). Then, by press-fitting the positioning protrusion 56 into the second positioning recess 100, the housing bodies 98 and 16 stacked vertically are positioned and fixed to each other.

なお、カバー部１８と最下層のハウジング本体１６の間に配設されるハウジング本体９８は、最下層のハウジング本体１６に比してロック機構を構成する係合枠体６２を有している以外は同一形状である。それゆえ、金型コストを削減してハウジング本体１６，９８を製造することができる。また、ロック機構を設けない場合には、ハウジング本体１６のみの使用とできることから、一層の構成の簡素化や部品管理の容易化を図ることができる。さらに、図９〜１０に示す本発明の第二の実施形態では、ハウジング本体９８，１６は上下２段に積層されていたが、積層するハウジング本体９８を増やすことにより容易に積層する段数を増やすことができる。 The housing body 98 disposed between the cover portion 18 and the lowermost housing body 16 has an engaging frame 62 that constitutes a locking mechanism as compared with the lowermost housing body 16. Have the same shape. Therefore, the housing bodies 16, 98 can be manufactured at a reduced mold cost. Further, when the lock mechanism is not provided, only the housing body 16 can be used, so that the configuration can be further simplified and the parts management can be facilitated. Further, in the second embodiment of the present invention shown in FIGS. 9 to 10, the housing bodies 98 and 16 are laminated in two upper and lower stages, but the number of stages to be easily laminated is increased by increasing the number of stacked housing bodies 98. be able to.

また、上記実施形態では、第一位置決め凹部を構成する貫通孔６８や第二位置決め凹部１００への位置決め突起５６の嵌合は圧入とされていたが挿通とされていてもよく、その場合のシート状補強部材９０の挟持は例えばロック機構４６，６２等のロック機構によって構成されていてもよい。さらに、第一位置決め凹部は、上記第一の実施形態のように貫通孔６８であってもよいし、第二位置決め凹部１００のような凹所であってもよい。加えて、位置決め突起５６と第一位置決め凹部を構成する貫通孔６８と第二位置決め凹部１００における凸部と凹部の組合せは、逆に凹部と凸部の組合せであってもよい。すなわち、カバー部１８や中間カバー部であるハウジング本体９８側に位置決め突起５６が設けられ、ハウジング本体１６，９８の上面２４に凹部が形成されていてもよい。 Further, in the above embodiment, the fitting of the positioning protrusion 56 into the through hole 68 forming the first positioning recess and the second positioning recess 100 is press-fitted, but may be inserted, and the sheet in that case. The sandwiching of the shape reinforcing member 90 may be configured by, for example, a locking mechanism such as a locking mechanism 46, 62. Further, the first positioning recess may be a through hole 68 as in the first embodiment, or may be a recess such as the second positioning recess 100. In addition, the combination of the convex portion and the concave portion in the through hole 68 forming the positioning protrusion 56 and the first positioning concave portion and the second positioning concave portion 100 may be a combination of the concave portion and the convex portion. That is, the positioning protrusion 56 may be provided on the cover portion 18 or the housing main body 98 side which is the intermediate cover portion, and the concave portion may be formed on the upper surface 24 of the housing main bodies 16 and 98.

加えて、シート状補強部材９０は例示のものに限定されず、樹脂製のシート材に接着層が設けられて電線１２が固着されるようにしたものや、布製のシート材に対して電線１２をソーイングにより固着したもの等、シート状で電線１２を固着保持できるものであれば任意のものが採用可能である。 In addition, the sheet-shaped reinforcing member 90 is not limited to the example, and the sheet material made of resin is provided with an adhesive layer so that the electric wire 12 is fixed to the sheet material, or the electric wire 12 is attached to the sheet material made of cloth. Any material can be adopted as long as it is in the form of a sheet and can hold and hold the electric wire 12 by sewing.

なお、上記実施形態から把握できる技術的思想について以下に記載する。 The technical ideas that can be grasped from the above embodiments will be described below.

（１）プレート状のハウジング本体と、前記ハウジング本体の長さ方向の前端側に設けられて、該ハウジング本体の上面に開口して複数並列配置された溝状の端子収容室と、複数の電線の端末に設けられて前記端子収容室にそれぞれ収容配置された複数の接続端子と、前記ハウジング本体の長さ方向の後端側に設けられて、前記端子収容室の後端側開口部から延び出す前記複数の電線を支持する電線支持部と、前記電線支持部の上面に載置されると共に前記複数の電線がそれぞれ並列状態で固着されたシート状補強部材と、前記ハウジング本体の前記上面に重ね合されて前記端子収容室を蓋覆すると共に前記シート状補強部材を前記電線支持部との間で挟持するカバー部とを備えているコネクタである。 (1) A plate-shaped housing body, a groove-shaped terminal accommodating chamber provided on the front end side in the length direction of the housing body and opened in parallel on the upper surface of the housing body, and a plurality of electric wires. A plurality of connection terminals provided in the terminal and accommodated and arranged in the terminal accommodating chamber, and provided on the rear end side in the length direction of the housing body and extending from the rear end side opening of the terminal accommodating chamber. An electric wire support portion that supports the plurality of electric wires to be put out, a sheet-like reinforcing member that is placed on the upper surface of the electric wire support portion and to which the plurality of electric wires are fixed in parallel, and on the upper surface of the housing body. It is a connector provided with a cover portion that is overlapped to cover the terminal accommodating chamber and sandwiches the sheet-shaped reinforcing member with the electric wire support portion.

技術的思想（１）のコネクタでは、ハウジング本体に設けられた端子収容室が上方に開口する溝形状を有していることから、電線の端末に設けられた接続端子を収容する工程を複数の端子収容室に対して複数の接続端子を一括して上方から嵌め入れることが可能となり、従来のように四方を周壁に囲まれた筒形状の端子収容室に１本ずつ接続端子を収容する場合に比して、飛躍的な作業性の向上を図ることができる。さらに、溝形状を有する端子収容室を採用した場合に懸念される端子収容室から延び出す電線への応力の集中も、端子収容室の後端側開口部から延び出す電線支持部により複数の電線が支持されることにより低減されている。加えて、端子収容室の後端側開口部から延び出す複数の電線が、シート状補強部材に並列状態で固着されて電線支持部の上面に載置されており、かつハウジング本体の上面に重ね合されるカバー部とハウジング本体の上面との間で挟持されていることから複数の電線へ外力が加わることが確実に回避乃至は低減されて、かかる部位の電線の強度担保を確実に実現することができる。それゆえ、電線として極細線を採用する場合にも、溝形状の端子収容室を採用することが可能となる。 In the connector of the technical idea (1), since the terminal accommodating chamber provided in the housing body has a groove shape that opens upward, a plurality of steps for accommodating the connection terminals provided in the terminal of the electric wire are performed. When multiple connection terminals can be fitted into the terminal storage chamber from above at once, and one connection terminal is stored in the tubular terminal storage chamber surrounded by peripheral walls on all sides as in the past. Compared to the above, it is possible to dramatically improve workability. Further, the concentration of stress on the electric wire extending from the terminal accommodating chamber, which is a concern when the terminal accommodating chamber having a groove shape is adopted, is also caused by the electric wire support portion extending from the rear end side opening of the terminal accommodating chamber. Is reduced by being supported. In addition, a plurality of electric wires extending from the rear end side opening of the terminal accommodating chamber are fixed in parallel to the sheet-shaped reinforcing member and placed on the upper surface of the electric wire support portion, and are overlapped on the upper surface of the housing body. Since it is sandwiched between the combined cover and the upper surface of the housing body, it is surely avoided or reduced that an external force is applied to a plurality of electric wires, and the strength of the electric wire at such a part is surely guaranteed. be able to. Therefore, even when an ultrafine wire is used as the electric wire, it is possible to use a groove-shaped terminal accommodating chamber.
