Description

本発明は、端子片をハウジングに組み付けて構成されるコネクタに関するものである。 The present invention relates to a connector configured by assembling a terminal piece to a housing.

従来、電気的接続を行う部位に使用されるコネクタにおいて、導電性金属板を打ち抜き加工して適所で折り曲げて端子片を形成し、合成樹脂製のハウジングに端子片を組み付けるようにしたものがある。そのような構造のコネクタでは、端子片をハウジングに組み付けた状態で端子片がハウジングから外れることを防止する必要があり、例えば、ハウジングに形成した端子挿入孔に端子片を挿入し、端子片の挿入方向に交差する向きにリテーナを差し込み、リテーナと端子片の凹部との係合により端子片を抜け止めするようにしたものがある（例えば特許文献１参照）。 2. Description of the Related Art Conventionally, there is a connector used in an electrical connection part, in which a conductive metal plate is punched and bent at an appropriate place to form a terminal piece, and the terminal piece is assembled to a synthetic resin housing. . In the connector having such a structure, it is necessary to prevent the terminal piece from being detached from the housing in a state where the terminal piece is assembled to the housing. For example, the terminal piece is inserted into a terminal insertion hole formed in the housing, and the terminal piece There is one in which a retainer is inserted in a direction crossing the insertion direction, and the terminal piece is prevented from coming off by engagement between the retainer and a recess of the terminal piece (see, for example, Patent Document 1).

特開２０１０−４９８４４号公報JP 2010-49844 A

上記特許文献１の技術では、ハウジング及び端子片とは別にリテーナを用いており、部品点数が増加すると共に、組み付けが煩雑化するという問題がある。また、端子片の所定部位にリテーナを差し込むため、端子片を端子挿入孔に対して挿入方向の所定位置に仮止めするべく、端子片に、切り起こした形状のランスを設け、ハウジングに、ランスが弾性的に嵌ることで端子片を抜け止めし得る係止溝を設けている。この係止溝はハウジング内に形成されており、ランスと係止溝との係合状態ではランスが端子挿入孔から係止溝側へ弾性的に突入しているため、リテーナを外しても外部からランスと係止溝との係合を解除することは困難であり、端子片のみの交換ができないという不都合もある。 In the technique of the above-mentioned Patent Document 1, a retainer is used separately from the housing and the terminal piece, and there are problems that the number of parts increases and the assembly becomes complicated. In addition, in order to insert the retainer into a predetermined portion of the terminal piece, a lance having a cut and raised shape is provided on the terminal piece in order to temporarily fix the terminal piece at a predetermined position in the insertion direction with respect to the terminal insertion hole. Is provided with a locking groove that can be elastically fitted to prevent the terminal piece from coming off. This locking groove is formed in the housing. When the lance is engaged with the locking groove, the lance elastically protrudes from the terminal insertion hole toward the locking groove, so that even if the retainer is removed, Therefore, it is difficult to release the engagement between the lance and the locking groove, and there is an inconvenience that only the terminal piece cannot be replaced.

本発明は、以上の背景に鑑み、端子片をハウジングに組み付けるコネクタにおいて、部品点数を増加することなく抜け止めし、かつ組み付けを容易にすることを課題とする。 In view of the above background, it is an object of the present invention to prevent a terminal piece from being detached without increasing the number of parts and to facilitate assembly in a connector for assembling a terminal piece to a housing.

上記課題を解決するために、本発明は、金属製板状体を曲げ加工して形成された端子片（４）と、前記端子片を保持するハウジング（３１）とを有するコネクタ（３３）であって、前記端子片は、長板状の基部（１３）と、前記基部の長手方向の一端から反転する向きに折り曲げられ、前記基部の他端に向けて延出することにより、前記基部に対して離間して対峙して、相手端子に弾性的に接触するように構成された接触部（４ａ）とを有し、前記基部は、第１の嵌合孔（３７）と、前記第１の嵌合孔に対して前記基部の長手方向に所定の間隔をおいて設けられた第２の嵌合孔（３８）とを有し、前記ハウジングは、前記基部を載置状態に支持する底面（３２ａ）と、前記底面の所定の位置に突設され、前記基部が前記底面に載置された状態で前記両嵌合孔のいずれにも嵌入可能であり、当該嵌入した状態では前記基部の前記長手方向へのスライドを規制する嵌入突部（３６）と、前記基部を受容しかつ前記底面上に載置し得るように構成された側壁（３２ｂ）とを有し、前記側壁が、前記嵌入突部が前記第１の嵌合孔に嵌入した状態では、前記基部の所定の縁部（１３ａ・１３ｂ・１３ｃ）に係合せず、前記嵌入突部が前記第２の嵌合孔に嵌入した状態では、前記所定の縁部に係合するオーバハング部（３４ａ・３４ｂ）を有し、前記基部を、前記嵌入突部が前記第１の嵌合孔に嵌入した状態から前記第２の嵌合孔に嵌入する状態に向かうスライド方向に移動可能とするために、前記嵌入突部の前記スライド方向に相反する側又は前記第１の嵌合孔の前記スライド方向に相反する側に前記底面に向かう斜面（３６ａ・３７ａ）又は曲面（３６ｂ）が設けられていることを特徴とする。 In order to solve the above problems, the present invention provides a connector (33) having a terminal piece (4) formed by bending a metal plate-like body and a housing (31) for holding the terminal piece. The terminal piece is bent in a direction to be inverted from one end in the longitudinal direction of the long plate-like base (13) and the base, and extends toward the other end of the base, thereby extending the base to the base. A contact portion (4a) configured to elastically contact a mating terminal while facing away from each other, and the base portion includes a first fitting hole (37) and the first portion A second fitting hole (38) provided at a predetermined interval in the longitudinal direction of the base portion with respect to the fitting hole, and the housing is a bottom surface for supporting the base portion in a mounted state. (32a) and a state where the base is placed at a predetermined position on the bottom surface and the base is placed on the bottom surface It is possible to fit into both of the fitting holes, and in the fitted state, a fitting projection (36) for restricting sliding of the base portion in the longitudinal direction, and receiving the base portion and mounting on the bottom surface. A side wall (32b) configured to be able to be placed, and the side wall has a predetermined edge (13a, 13b) of the base in a state where the fitting protrusion is fitted into the first fitting hole. In the state where the fitting protrusion does not engage with 13c) and the fitting protrusion is fitted into the second fitting hole, it has an overhang portion (34a, 34b) that engages with the predetermined edge portion, and the base portion is In order to enable the insertion protrusion to move in the sliding direction from the state of being inserted into the first fitting hole to the state of being inserted into the second fitting hole, the insertion protrusion is opposite to the sliding direction. Opposite to the sliding direction of the first fitting hole or the first fitting hole Slope toward the bottom surface (36a · 37a) or a curved surface (36b) is characterized in that provided in the.

この構成によれば、端子片の基部をハウジング内の底面に載置状態にすることにより、底面の嵌入突部が基部の第１の嵌合孔に嵌入した状態となり、その状態では基部の所定の縁部がハウジングのオーバハング部に係合せず、その状態から基部をスライドさせることにより、嵌入突部が第２の嵌合孔に嵌入した組み付け状態になり、その組み付け状態では、基部の所定の縁部がオーバハング部に係合して基部が底面から離反することが防止され、かつ嵌入突部が第２の嵌合孔に嵌入した状態になることにより、基部が反対側へスライドすることが防止されるため、端子片がハウジング内に抜け止め状態に保持される。上記基部のスライドにおいて、嵌入突部又は第１の嵌合孔のスライド方向に相反する側に面取り部が設けられていることから、基部を容易にスライド方向に移動させることができる。このように、端子片の基部をハウジングの底面に載置状態にした後にスライドさせるという簡単な作業で、ハウジングに端子片が組み付けられたコネクタを構成することができるため、リテーナ等の別部品を用いる必要がなく、部品点数が増加することなく、端子片をハウジングに対して位置決めかつ抜け止め状態に組み付けることができる。 According to this configuration, by placing the base portion of the terminal piece on the bottom surface in the housing, the fitting protrusion on the bottom surface is fitted into the first fitting hole of the base portion, and in this state, the predetermined portion of the base portion is set. By sliding the base from that state without engaging the overhanging portion of the housing, the fitting protrusion is fitted into the second fitting hole, and in this assembled state, It is possible to prevent the base portion from separating from the bottom surface by engaging the edge with the overhang portion, and the base portion can slide to the opposite side when the insertion protrusion is inserted into the second fitting hole. Therefore, the terminal piece is held in the housing so as not to be detached. In the slide of the base portion, since the chamfered portion is provided on the side opposite to the sliding direction of the fitting protrusion or the first fitting hole, the base portion can be easily moved in the sliding direction. In this way, since the base part of the terminal piece is placed on the bottom surface of the housing and then slid, it is possible to constitute a connector in which the terminal piece is assembled to the housing. It is not necessary to use the terminal piece and the terminal piece can be assembled to the housing in a positioning and retaining state without increasing the number of parts.

また、上記の発明において、前記所定の縁部が、第１の係合縁部（１３ａ）と、前記第１の係合縁部に対して長手方向に間隔をおいた位置に設けられた第２の係合縁部（１３ｂ・１３ｄ）とにより構成され、前記オーバハング部が、前記第１の係合縁部と係合する第１のオーバハング部（３４ａ）と、前記第２の係合縁部と係合する第２のオーバハング部（３４ｂ・３４ｃ）とにより構成されているとよい。 In the above invention, the predetermined edge portion is provided at a position that is spaced apart in the longitudinal direction from the first engagement edge portion (13a) and the first engagement edge portion. The first engagement edge (34a) engaging with the first engagement edge, and the second engagement edge. It is good to be comprised by the 2nd overhang part (34b * 34c) engaged with a part.

この構成によれば、嵌入突部が第２の嵌合孔に嵌入した状態で、第１の係合縁部と第１のオーバハング部との係合に加えて、更に第２の係合縁部と第２のオーバハング部とが係合することから、嵌入突部が第２の嵌合孔に嵌入した組み付け状態において、基部の縁部に対して複数箇所でオーバハング部と係合するため、基部を安定して保持することができる。 According to this configuration, in addition to the engagement between the first engagement edge portion and the first overhang portion in the state where the insertion protrusion is fitted into the second fitting hole, the second engagement edge is further provided. Since the engagement portion is engaged with the second overhang portion, in the assembled state in which the fitting protrusion is fitted into the second fitting hole, the overhang portion is engaged with the edge portion of the base portion at a plurality of locations. The base can be stably held.

また、上記の発明において、前記第１及び第２の係合縁部（１３ａ・１３ｂ・１３ｄ）が、長手方向について前記第２の嵌合孔（３８）に対して互いに異なる側に配置されているとよい。 In the above invention, the first and second engaging edge portions (13a, 13b, 13d) are arranged on different sides with respect to the second fitting hole (38) in the longitudinal direction. It is good to be.

この構成によれば、嵌入突部が第２の嵌合孔に嵌入した状態で、その嵌入部位に対して、第１及び第２の係合縁部が互いに異なる側となる両側で対応する各オーバハング部と係合することから、基部における第２の嵌合孔が設けられた部分の浮き上がりが防止され、第２の嵌合孔への嵌入突部の嵌入状態を安定して保持することができる。 According to this configuration, in a state where the fitting protrusion is fitted into the second fitting hole, each of the fitting portions corresponding to both sides where the first and second engaging edge portions are different from each other. Since it engages with the overhang portion, it is possible to prevent the portion of the base portion provided with the second fitting hole from being lifted, and to stably hold the fitting state of the fitting protrusion into the second fitting hole. it can.

また、上記の発明において、前記所定の縁部が、前記基部の左右に拡幅された一対の係合縁部（１３ａ・１３ｂ）からなり、前記オーバハング部（３４ａ・３４ｂ）が、左右の前記側壁に一対設けられているとよい。この構成によれば、基部の左右で係合縁部とオーバハング部とを係合させることができ、基部の左右方向の揺動変位が防止され、第２の嵌合孔への嵌入突部の嵌入状態を安定して保持することができる。 Further, in the above invention, the predetermined edge portion includes a pair of engagement edge portions (13a and 13b) widened to the left and right of the base portion, and the overhang portions (34a and 34b) are formed on the left and right side walls. A pair may be provided. According to this configuration, the engagement edge portion and the overhang portion can be engaged with each other on the left and right sides of the base portion, and the rocking displacement of the base portion in the left-right direction can be prevented, and the fitting protrusion into the second fitting hole can be prevented. The inserted state can be stably maintained.

また、上記の発明において、前記所定の縁部が、前記基部の長手方向の前記一端の近傍から長手方向に延出する一対の係合縁部（１３ｄ）からなり、前記オーバハング部（３４ｃ）が、前記側壁における前記基部の長手方向の前記一端側に設けられているとよい。この構成によれば、基部を、嵌入突部が第１の嵌合孔に嵌入した状態から第２の嵌合孔に嵌入する状態に向けてスライドさせる際に、基部の両嵌合孔間となる部分が嵌入突部を一旦乗り越えるため基部の一部が浮き上がり、それに伴って所定の縁部がオーバハング部による係合部位に入り難くなる虞があるが、基部の上記乗り越える部分から離れる方向に所定の縁部が延出していることにより、上記浮き上がりによる影響が抑制されるためオーバハング部による係合部位に所定の縁部を入れ易くなる。 In the above invention, the predetermined edge portion includes a pair of engagement edge portions (13d) extending in the longitudinal direction from the vicinity of the one end in the longitudinal direction of the base portion, and the overhang portion (34c) is formed. It is good to provide in the one end side of the longitudinal direction of the base in the side wall. According to this configuration, when the base is slid from the state in which the fitting protrusion is fitted into the first fitting hole to the state in which the fitting is fitted into the second fitting hole, Part of the base part rises and the part of the base part rises, and there is a possibility that the predetermined edge part will not easily enter the engagement part by the overhang part, but it is predetermined in the direction away from the part of the base part to get over. Since the influence of the above-described lifting is suppressed, the predetermined edge can be easily put in the engagement portion by the overhang portion.

また、上記の発明において、前記ハウジングに、前記嵌入突部が前記第２の嵌合孔に嵌入した位置で、前記基部の前記スライド方向の限度を定めるストッパ（３２ｃ）が設けられているとよい。この構成によれば、第１の嵌合孔に嵌入突部が突入した状態から基部をスライドさせると、嵌入突部が第２の嵌合孔に嵌入した状態で基部の長手方向の一端側へのスライドが止められるため、ハウジングに組み付ける基部の位置決めを確実かつ容易に行うことができる。 In the above invention, the housing may be provided with a stopper (32c) that defines a limit in the sliding direction of the base at a position where the fitting protrusion is fitted into the second fitting hole. . According to this configuration, when the base is slid from the state in which the fitting protrusion is inserted into the first fitting hole, the one end side in the longitudinal direction of the base is inserted in the state in which the fitting protrusion is inserted into the second fitting hole. Therefore, the base portion to be assembled to the housing can be positioned reliably and easily.

このように本発明によれば、端子片の基部をハウジング内の底面に載置した状態でスライドさせるという簡単な作業で、ハウジングに端子片が組み付けられたコネクタとすることができ、端子片のハウジングへの組み付け作業が容易であると共に、リテーナ等の別部品を用いる必要がなく、部品点数が増加することなく、端子片をハウジングに対して位置決めかつ抜け止め状態に組み付けることができる。 Thus, according to the present invention, it is possible to provide a connector in which the terminal piece is assembled to the housing by a simple operation of sliding the base of the terminal piece placed on the bottom surface in the housing. Assembling work to the housing is easy, it is not necessary to use separate parts such as a retainer, and the terminal piece can be positioned and assembled with respect to the housing without increasing the number of parts.

以下、本発明の実施の形態を、図面を参照しながら説明する。図１は、本発明に基づく連鎖状端子１となる前の打ち抜き加工後の展開状態を示す要部平面図であり、図２は、図1の展開状態から折り曲げ加工された連鎖状端子１を示す要部斜視図である。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a main part plan view showing a developed state after punching before becoming a chained terminal 1 according to the present invention, and FIG. 2 shows a chained terminal 1 bent from the developed state of FIG. It is a principal part perspective view shown.

図１に示されるように、例えばりん青銅の薄板状金属板から打ち抜き加工されることにより、後記するリールのハブにコイル状に巻回される巻回方向に帯状に形成された帯状のキャリア部２と、キャリア部２の長手方向に所定のピッチで並べられた複数の展開形状体３とが１枚の板状に形成されている。展開形状体３の所定の部分（図１の二点鎖線で示された部分）で折り曲げ加工することにより、図２に示される端子片４が形成される。 As shown in FIG. 1, for example, a band-shaped carrier portion formed in a band shape in a winding direction wound in a coil shape on a hub of a reel described later by being punched from a thin sheet metal plate of phosphor bronze. 2 and a plurality of developed shapes 3 arranged at a predetermined pitch in the longitudinal direction of the carrier portion 2 are formed in a single plate shape. A terminal piece 4 shown in FIG. 2 is formed by bending a predetermined portion of the developed shape body 3 (portion shown by a two-dot chain line in FIG. 1).

展開形状体３は、キャリア部２の長手方向に延在する両側縁の一方から横方向（キャリア部２の長手方向に直交する向き）に延出するように形成されている。なお、展開形状体３は、キャリア部２から狭幅部分を介して同一面内で横方向に延出された接続部１１を介してキャリア部２と結合されている。接続部１１には、切り起こされる前の展開状態に形成されたかしめ片１２ａ・１２ｂが設けられている。接続部１１のキャリア部２とは相反する側には、キャリア部２の長手方向にオフセットして接続部１１から横方向に更に延出され、かつ接続部１１に対して延出方向（横方向）に沿う軸線Ｌ周り（軸線Ｌの周方向）に折り曲げられた基部１３と、接触部展開部１４とがこの順に一体に形成されている。 The developed shape body 3 is formed so as to extend in the lateral direction (direction perpendicular to the longitudinal direction of the carrier portion 2) from one of both side edges extending in the longitudinal direction of the carrier portion 2. Note that the developed shape body 3 is coupled to the carrier portion 2 via a connection portion 11 extending in the lateral direction within the same plane from the carrier portion 2 via a narrow width portion. The connecting portion 11 is provided with crimped pieces 12a and 12b formed in an unfolded state before being cut and raised. On the side opposite to the carrier part 2 of the connection part 11, the carrier part 2 is offset in the longitudinal direction and further extends in the lateral direction from the connection part 11, and extends in the lateral direction with respect to the connection part 11 (lateral direction). ) Along the axis L (circumferential direction of the axis L) and the contact portion expanding portion 14 are integrally formed in this order.

このように形成された展開形状体３を、図１の二点鎖線で示される部分で所定方向に折り曲げることにより、図２に示される端子片４が形成される。なお、各二点鎖線は折り曲げの概略位置を示すものであり、必ずしも二点鎖線で折り曲げなくてもよい。例えば、二点鎖線を含む部分または隣り合う二点鎖線間で円弧状に曲成したりする場合を含むものとする。また、本実施形態の説明では円弧状に曲げる場合を曲成するとして用いるが、特に円弧状に限定するものではない。 The developed shape body 3 formed in this way is bent in a predetermined direction at a portion indicated by a two-dot chain line in FIG. 1, thereby forming a terminal piece 4 shown in FIG. 2. In addition, each two-dot chain line shows the approximate position of folding, and it is not always necessary to bend the two-dot chain line. For example, a case where a portion including a two-dot chain line or an adjacent two-dot chain line is bent in an arc shape is included. In the description of the present embodiment, the case of bending in an arc shape is used as a bend, but it is not particularly limited to an arc shape.

接続部１１は、キャリア部２と同一面となる矩形長板状に形成された部分と、その長板状のキャリア部２側で両側方に延出する一対の上記かしめ片１２ａと、基部１３側で両側方に突出する一対の上記かしめ片１２ｂとを有する。キャリア部２側のかしめ片１２ａは、後記するケーブル２２の被覆をかしめにより把持するものであり、基部１３側のかしめ片１２ｂはケーブル２２の芯線をかしめにより把持するものである。 The connection portion 11 includes a portion formed in a rectangular long plate shape that is the same surface as the carrier portion 2, a pair of the above caulking pieces 12 a extending to both sides on the long plate-like carrier portion 2 side, and a base portion 13. And a pair of the above caulking pieces 12b protruding on both sides on the side. The caulking piece 12a on the carrier portion 2 side grips the cover of the cable 22 described later by caulking, and the caulking piece 12b on the base portion 13 side grips the core wire of the cable 22 by caulking.

基部１３は、上述したように接続部１１からキャリア部２の長手方向にオフセットして、キャリア部２の長手方向に対して直交する側方となる横方向に帯状に延出するように形成されている。基部１３には、基部１３の延出方向である長手方向に直交する左右方向に拡幅された一対の第１の係合縁部１３ａと、第１の係合縁部１３ａに対して基部１３の長手方向であってキャリア部２側とは相反する側に所定の間隔をおいた位置で左右に拡幅された一対の第２の係合縁部１３ｂとが形成されている。これら各係合縁部１３ａ・１３ｂは、それぞれ所定の縁部に対応する。 As described above, the base portion 13 is formed so as to be offset in the longitudinal direction of the carrier portion 2 from the connecting portion 11 and to extend in a strip shape in a lateral direction orthogonal to the longitudinal direction of the carrier portion 2. ing. The base portion 13 includes a pair of first engagement edge portions 13a widened in the left-right direction orthogonal to the longitudinal direction that is the extending direction of the base portion 13, and the base portion 13 with respect to the first engagement edge portion 13a. A pair of second engagement edge portions 13b that are widened to the left and right at a predetermined interval are formed on the side opposite to the carrier portion 2 side in the longitudinal direction. Each of the engagement edge portions 13a and 13b corresponds to a predetermined edge portion.

図示例では、第１及び第２の係合縁部１３ａ・１３ｂが設けられた部分の幅は、それぞれ同一の一定の幅に形成されているが、それぞれ異なる幅であってもよい。また、基部１３における第１の係合縁部１３ａと第２の係合縁部１３ｂとの間の胴部１３ｃは各係合縁部１３ａ・１３ｂによる幅よりも狭い一定の幅に形成されている。 In the illustrated example, the widths of the portions where the first and second engaging edge portions 13a and 13b are provided are the same constant width, but may be different widths. Further, the body portion 13c between the first engagement edge portion 13a and the second engagement edge portion 13b in the base portion 13 is formed to have a constant width that is narrower than the width of the engagement edge portions 13a and 13b. Yes.

接触部展開部１４は、基部１３の長手方向の一端から基部１３の延出方向に延出される。接触部展開部１４には、基部１３側から、第１の係合縁部１３ａにおける幅よりも両側を狭められた反転部１４ａと、反転部１４ａに対して両側を緩やかな円弧状に狭められた逆反り部１４ｂと、反転部１４ａと略同じ幅の接点部１４ｃと、延出方向に至るに連れて幅が狭まるようにされた折り返し部１４ｄと、先細り形状の延出端部１４ｅとが、この順に連続して形成されている。 The contact portion expanding portion 14 extends in the extending direction of the base portion 13 from one end in the longitudinal direction of the base portion 13. The contact portion expanding portion 14 is narrowed from the base portion 13 side to a reversing portion 14a narrowed on both sides than the width of the first engagement edge portion 13a, and to both sides of the reversing portion 14a in a gentle arc shape. A reverse warped portion 14b, a contact portion 14c having substantially the same width as the reversing portion 14a, a folded portion 14d whose width is narrowed in the extending direction, and a tapered extending end portion 14e. These are formed successively in this order.

このようにして形成された展開形状体３を上記した軸線Ｌ及び各二点鎖線で適宜折り曲げて、図２に示されるように基部１３と接触部４ａとからなる端子片４が形成される。 The developed shape body 3 formed in this manner is appropriately bent along the axis L and the two-dot chain lines described above to form the terminal strip 4 composed of the base portion 13 and the contact portion 4a as shown in FIG.

ここで、接触部展開部１４を曲成して形成される接触部４ａの形成要領について説明する。基部１３の長手方向の一端である第２の係合縁部１３ｂとの境界部分から、反転部１４ａが接続部１１側に反転する向きに半円状に曲成される。逆反り部１４ｂは、基部１３における第１の係合縁部１３ａが設けられた部分と略平行に対峙した状態で接続部１１側に延出された後、基部１３から離反する向きに折り曲げられ、斜め後方（第２の係合縁部１３ｂ側）に延出される。逆反り部１４ｂに連続する接点部１４ｃは、基部１３に対して最も離反して位置し、逆反り部１４ｂの延出方向に対してＵターンして基部１３側に向かうように略半円状に曲成される。接点部１４ｃに連続する折り返し部１４ｄは、接点部１４ｃから基部１３に向けて近付く向きに延出されるが、途中までは逆反り部１４ｂの接点部１４ｃ側部分と平行し、その後、斜め後方（基部１３における第１の係合縁部１３ａが設けられた部分）に延出される。折り返し部１４ｄに連続する延出端部１４ｅは、基部１３に接近した位置で反転する向きに曲成される。このようにして、端子片４における接触部４ａが形成される。 Here, the formation point of the contact part 4a formed by bending the contact part expansion | deployment part 14 is demonstrated. A reversing portion 14a is bent in a semicircular shape from the boundary portion with the second engagement edge portion 13b, which is one end in the longitudinal direction of the base portion 13, in a direction to be reversed to the connection portion 11 side. The reverse warped portion 14b is extended toward the connecting portion 11 in a state of facing the portion in the base 13 where the first engagement edge 13a is provided, and then bent in a direction away from the base 13. , Extending obliquely rearward (second engagement edge 13b side). The contact portion 14c that continues to the reverse warp portion 14b is located farthest away from the base portion 13, and is substantially semicircular so as to make a U-turn toward the base portion 13 side in the extending direction of the reverse warp portion 14b. It is composed. The folded portion 14d continuous with the contact portion 14c extends in a direction approaching the base portion 13 from the contact portion 14c, but is partially parallel to the contact portion 14c side portion of the reverse warped portion 14b, and then obliquely rearward ( The base portion 13 is extended to a portion provided with the first engagement edge portion 13a. The extended end portion 14e continuing to the folded portion 14d is bent in a direction that is reversed at a position close to the base portion 13. Thus, the contact part 4a in the terminal piece 4 is formed.

また、基部１３は、接続部１１に対して上記した軸線Ｌの周方向となる軸線Ｌ周りに折り曲げられている。本実施形態では接続部１１及び基部１３の主面同士が互いに直交するように、基部１３が、接続部１１すなわちキャリア部２の主面（表裏面）に対して直角に折り曲げられている。なお、接続部１１と基部１３とは、軸線Ｌで直角に折り曲げられる必要は無く、例えば円弧状の曲面を有するように緩やかに折り曲げられていてもよい。 The base portion 13 is bent around the axis L that is the circumferential direction of the axis L described above with respect to the connecting portion 11. In the present embodiment, the base portion 13 is bent at a right angle with respect to the connection portion 11, that is, the main surface (front and back surfaces) of the carrier portion 2 so that the main surfaces of the connection portion 11 and the base portion 13 are orthogonal to each other. Note that the connecting portion 11 and the base portion 13 do not need to be bent at a right angle along the axis L, and may be gently bent so as to have, for example, an arcuate curved surface.

このように展開形状体３を折り曲げ加工して形成された端子片４は、図３（ａ）に示されるように形成される。図３（ａ）は端子片４を接触部４ａ側から見た図であり、図３（ｂ）は、図３（ａ）のIIIｂ線の矢印方向から見たケーブル結合状態の図であり、図３（ｃ）は、図３（ｂ）のIIIｃ線の矢印方向から見た図である。 The terminal piece 4 formed by bending the developed shape body 3 in this way is formed as shown in FIG. 3 (a) is a view of the terminal piece 4 as viewed from the contact portion 4a side, and FIG. 3 (b) is a view of the cable connection state as seen from the direction of the arrow of the IIIb line in FIG. 3 (a). FIG.3 (c) is the figure seen from the arrow direction of the IIIc line | wire of FIG.3 (b).

端子片４は、キャリア部２の長手方向に所定のピッチで複数並べられ、キャリア部２とは接続部１１を介してそれぞれ連結され、連鎖状端子１となる。連鎖状端子１は、図４に示されるように、リール２１のハブ２１ａにコイル状に巻回されてユーザに提供される。このようにリール２１に巻かれた状態では、端子片４には積層方向（図３（ａ）の矢印Ｆにより示される方向）に圧力が掛かることになる。この積層方向は、キャリア部２の主面に直交する軸線（図３（ａ）の軸線Ｃｃ）方向である。 A plurality of terminal pieces 4 are arranged at a predetermined pitch in the longitudinal direction of the carrier part 2, and are connected to the carrier part 2 via connection parts 11 to form a chain terminal 1. As shown in FIG. 4, the chain terminal 1 is provided to the user by being wound around the hub 21 a of the reel 21 in a coil shape. Thus, in the state wound on the reel 21, pressure is applied to the terminal pieces 4 in the stacking direction (the direction indicated by the arrow F in FIG. 3A). This stacking direction is the direction of the axis (axis Cc in FIG. 3A) orthogonal to the main surface of the carrier portion 2.

従来例のものでは、りん青銅等の金属製薄板から打ち抜かれた帯状の板状体を、その表裏面側に折り曲げて接触部を形成しており、そのように形成された連鎖状端子をリールに巻いた場合には、接触部の折り曲げによる変形方向において積層方向となる部分が生じるため、積層方向の圧力（上記Ｆ）により接触部に新たな変形が生じる場合がある。接触部に変形が生じた場合には、相手端子との接触において設計通りの適切な接触圧が得られなくなるという虞がある。 In the conventional example, a strip-shaped plate punched out from a thin metal plate such as phosphor bronze is bent to the front and back sides to form a contact portion, and the chained terminal thus formed is reeled. In the case where the contact portion is wound, a portion that becomes the stacking direction is generated in the deformation direction due to the bending of the contact portion, and thus the contact portion may be newly deformed by the pressure in the stacking direction (F). When the contact portion is deformed, there is a possibility that an appropriate contact pressure as designed cannot be obtained in contact with the mating terminal.

それに対して、本発明による基部１３及び接触部４ａは、連鎖状端子１の端子片４として形成された場合には、積層方向（リール２１の半径方向）に起立する壁として形成される。連鎖状端子１がリール２１のハブ２１ａに巻かれた状態で積層方向に加わる圧力（図３（ａ）の矢印Ｆ）は、基部１３及び接触部４ａの壁として起立する方向に加わることになる。壁はその起立方向に加わる圧力に対しては大きな耐力を有するため、上記積層方向に加わる圧力に対して基部１３及び接触部４ａは変形し難い。 On the other hand, when the base portion 13 and the contact portion 4a according to the present invention are formed as the terminal pieces 4 of the chain terminal 1, they are formed as walls that stand in the stacking direction (the radial direction of the reel 21). The pressure (arrow F in FIG. 3A) applied in the stacking direction in a state where the chain terminal 1 is wound around the hub 21a of the reel 21 is applied in the direction in which the base terminal 13 and the contact portion 4a stand up. . Since the wall has a large proof strength against the pressure applied in the standing direction, the base 13 and the contact portion 4a are not easily deformed against the pressure applied in the stacking direction.

また、図３（ａ）に示されるように、積層方向（軸線Ｃｃ方向）に対して、基部１３の最大幅（各係合縁部１３ａ・１３ｂにおける幅）が接触部４ａの最大幅（図示例では接点部１４ｃの幅）よりも大きく、基部１３の最大幅内に接触部４ａの全体が収まっている。これにより、基部１３が接触部４ａの変形を防止する防止片としての機能を有し、特に従来例のように専用の端子変形防止片を形成する必要が無い。 As shown in FIG. 3A, the maximum width of the base portion 13 (the width at each of the engagement edge portions 13a and 13b) is the maximum width of the contact portion 4a (see FIG. 3) with respect to the stacking direction (axis Cc direction). In the example shown, the width of the contact portion 14 c is larger), and the entire contact portion 4 a is within the maximum width of the base portion 13. Thereby, the base 13 has a function as a prevention piece for preventing the deformation of the contact portion 4a, and it is not particularly necessary to form a dedicated terminal deformation prevention piece as in the conventional example.

なお、図３（ｂ）に示されるように、一方のかしめ片１２ａをケーブル２２の被覆部分にかしめ、他方のかしめ片１２ｂをケーブル２２の芯線にかしめることにより、端子片４にケーブル２２が結合される。端子片４の使用状態の一例としては、図３（ｂ）に示されるように、接触部４ａの接点部１４ｃが相手端子２３の被接触部２３ａと当接する。接点部１４ｃと被接触部２３ａとの接触圧を大きくするためには、接触部４ａの当接方向（図の矢印Ａ方向）の変形量を大きくするとよい。 3B, the caulking piece 12a is caulked to the covering portion of the cable 22, and the other caulking piece 12b is caulked to the core wire of the cable 22, whereby the cable 22 is attached to the terminal piece 4. As shown in FIG. Combined. As an example of the usage state of the terminal piece 4, as shown in FIG. 3B, the contact portion 14 c of the contact portion 4 a comes into contact with the contacted portion 23 a of the mating terminal 23. In order to increase the contact pressure between the contact portion 14c and the contacted portion 23a, the amount of deformation in the contact direction of the contact portion 4a (the direction of arrow A in the figure) may be increased.

端子片４の材質や肉厚を変えない場合には、接触部４ａの当接方向の変形量を大きくするべく基部１３から接点部１４ｃまでの距離を大きくすることが考えられる。従来の連鎖状端子のように接触部の当接方向がリール２１に対する積層方向になっている場合には、接触部の当接方向の変形量を増大すると、層間隔が拡がることになり、同一径のリールに対する巻き付け量が減少してしまう。 When the material and thickness of the terminal piece 4 are not changed, it is conceivable to increase the distance from the base portion 13 to the contact portion 14c in order to increase the amount of deformation in the contact direction of the contact portion 4a. In the case where the contact direction of the contact portion is the stacking direction with respect to the reel 21 as in the conventional chain terminal, when the amount of deformation in the contact direction of the contact portion is increased, the layer spacing is increased and the same. The winding amount with respect to the reel of the diameter is reduced.

それに対して、本発明による連鎖状端子１の場合には、接触部４ａの当接方向は積層方向ではなく、巻回方向（リール２１の円周方向）になるため、積層間隔が拡がらない。なお、巻回方向である各端子片４のピッチ間隔が拡がることになるが、径方向に対しては基部１３の幅で一定であり、基部１３の幅は、本実施形態のような接触部４ａの突出量（基部１３から接点部１４ｃに至る長さ）に対して小さいため、リール２１への巻回数（周回数）を増大し得ることにより、同一径のリールに対する巻き付け量の減少を抑制し得る。 On the other hand, in the case of the chain terminal 1 according to the present invention, the contact direction of the contact portion 4a is not the stacking direction but the winding direction (circumferential direction of the reels 21), so that the stacking interval does not increase. . In addition, although the pitch space | interval of each terminal piece 4 which is a winding direction expands, it is constant with the width | variety of the base 13 with respect to radial direction, and the width | variety of the base 13 is a contact part like this embodiment. 4a is small with respect to the protruding amount (the length from the base portion 13 to the contact portion 14c), so that the number of windings (number of laps) around the reel 21 can be increased, thereby suppressing a decrease in the winding amount with respect to the reel having the same diameter. Can do.

また、使用時において相手端子２３に当接して接触部４ａが変形することにより、接点部１４ｃが基部１３に大きく近付く。それにより延出端部１４ｅは、基部１３に当接した後、図３（ｂ）・（ｃ）の矢印Ｂにより示されるようにかしめ片１２ｂに近付く向きに変位する。 In addition, the contact portion 14 c comes close to the base portion 13 by contacting the mating terminal 23 and deforming the contact portion 4 a during use. As a result, the extended end portion 14e contacts the base portion 13, and then is displaced in a direction approaching the caulking piece 12b as indicated by an arrow B in FIGS. 3 (b) and 3 (c).

一方、延出端部１４ｅに近い方となるかしめ片１２ｂは、ケーブル２２の芯線に対してかしめた場合には、図３（ｃ）に示されるように、高さ（接続部１１からの突出量）が低くなる。かしめ片１２ｂの接続部１１からの高さ方向は延出端部１４ｅの上記矢印Ｂの変位方向と干渉する方向であるが、かしめ片１２ｂの高さが低くなるため、延出端部１４ｅの上記変位におけるかしめ片１２ｂとの干渉が回避される。これは、基部１３に対して側方に接続部１１が位置することによる効果であり、接触部４ａの変形量を大きくすることができるため、相手端子２３との接触圧の設定に対して容易に対応でき、汎用性の高い連鎖状端子１を提供し得る。 On the other hand, when the caulking piece 12b that is closer to the extended end portion 14e is caulked with respect to the core wire of the cable 22, as shown in FIG. Quantity) is low. The height direction of the caulking piece 12b from the connecting portion 11 is a direction that interferes with the displacement direction of the arrow B of the extending end portion 14e. However, since the height of the caulking piece 12b is reduced, the extending end portion 14e Interference with the caulking piece 12b in the displacement is avoided. This is an effect due to the connection portion 11 being positioned laterally with respect to the base portion 13, and since the deformation amount of the contact portion 4 a can be increased, it is easy to set the contact pressure with the mating terminal 23. It is possible to provide a highly versatile chain terminal 1.

図５は、端子片４をハウジング３１に組み付ける要領を示す斜視図である。なお、端子片４には、図３（ｂ）・（ｃ）と同様にケーブル２２が結合されている。ハウジング３１は、図６に併せて示されるように、端子片４の基部１３を受容する凹部３２を有する箱型の矩形ブロック状に形成されている。ハウジング３１に端子片４が組み付けられて、図７に示されるコネクタ（本図示例では雄型コネクタ）３３となり、ユーザ側での取扱い単位となる。なお、ハウジング３１の外形は、図示例に限られるものではなく、コネクタ３３が取り付けられる相手部材に応じて種々の形状に形成される。 FIG. 5 is a perspective view showing a procedure for assembling the terminal piece 4 to the housing 31. In addition, the cable 22 is couple | bonded with the terminal piece 4 similarly to FIG.3 (b) * (c). The housing 31 is formed in a box-shaped rectangular block shape having a recess 32 for receiving the base portion 13 of the terminal piece 4 as shown in FIG. The terminal piece 4 is assembled to the housing 31 to form a connector 33 (male connector in the illustrated example) shown in FIG. 7, which is a handling unit on the user side. Note that the outer shape of the housing 31 is not limited to the illustrated example, and may be formed in various shapes according to a mating member to which the connector 33 is attached.

凹部３２は、基部１３の平面形状（図５における上面視）に対応した形状の底面３２ａと、底面３２ａにおける長手方向（基部１３の長手方向に対応）に直交する幅方向（図５における左右方向）の両側縁で立ち上げられた両側壁３２ｂと、底面３２ａにおける基部１３の長手方向の一端部側（図５における前側）で立ち上げられた端壁３２ｃとにより、底面３２ａに基部１３が載置された状態の端子片４を三方から受容するように形成されている。また、凹部３２は、底面３２ａとは相反する側に開放された開口３２ｄを有する。なお、凹部３２の端壁３２ｃとは相反する側には、両側壁３２ｂよりも幅が狭くされ、かつ幅方向の一側（図５の左側）に偏倚して端壁３２ｃとは相反する側に開口する小幅凹部３２ｅが設けられている。この小幅凹部３２ｅの偏倚は、基部１３の幅方向一側にて曲折された接続部１１に対応するものである。 The concave portion 32 has a bottom surface 32a having a shape corresponding to the planar shape of the base portion 13 (viewed from the top in FIG. 5), and a width direction orthogonal to the longitudinal direction (corresponding to the longitudinal direction of the base portion 13) in the bottom surface 32a ) And the end wall 32c raised on one end side in the longitudinal direction of the base portion 13 on the bottom surface 32a (front side in FIG. 5), the base portion 13 is mounted on the bottom surface 32a. The terminal piece 4 in the placed state is formed so as to be received from three directions. Moreover, the recessed part 32 has the opening 32d opened on the opposite side to the bottom face 32a. The side opposite to the end wall 32c of the recess 32 is narrower than the side walls 32b and is biased to one side in the width direction (left side in FIG. 5) and is opposite to the end wall 32c. A small-width concave portion 32e that is open at the top is provided. The deviation of the small-width concave portion 32e corresponds to the connection portion 11 bent on one side in the width direction of the base portion 13.

両側壁３２ｂには、凹部３２内に互いに対向して突出するように形成されたそれぞれ一対の第１及び第２のオーバハング部３４ａ・３４ｂが、凹部３２の長手方向（図５における前後方向）に所定長（図５の距離ｂ）離隔して配設されている。第１及び第２のオーバハング部３４ａ・３４ｂの側壁３２ｂからの突出量は、接触部４ａの幅よりは広い間隔で対向し、基部１３の第１及び第２の係合縁部１３ａ・１３ｂによる幅よりは狭い。第１及び第２のオーバハング部３４ａ・３４ｂの端壁３２ｃ側は底面３２ａから立ち上げられているが、第１及び第２のオーバハング部３４ａ・３４ｂの小幅凹部３２ｅ側には、底面３２ａとの間に隙間を形成する第１及び第２の係合溝３５ａ・３５ｂがそれぞれ設けられている。第１及び第２の係合溝３５ａ・３５ｂの幅（隙間）は、第１及び第２の係合縁部１３ａ・１３ｂが大きくがたつかない程度に差し込み可能な大きさであってよい。 A pair of first and second overhang portions 34a and 34b formed on both side walls 32b so as to protrude opposite to each other in the recess 32 are provided in the longitudinal direction of the recess 32 (the front-rear direction in FIG. 5). They are spaced apart by a predetermined length (distance b in FIG. 5). The protrusion amounts of the first and second overhang portions 34a and 34b from the side wall 32b are opposed to each other at a distance wider than the width of the contact portion 4a, and are caused by the first and second engagement edge portions 13a and 13b of the base portion 13. It is narrower than the width. The end wall 32c side of the first and second overhang portions 34a and 34b is raised from the bottom surface 32a. However, the first and second overhang portions 34a and 34b are formed on the side of the narrow recess 32e with the bottom surface 32a. First and second engaging grooves 35a and 35b are formed to form a gap therebetween. The width (gap) of the first and second engagement grooves 35a and 35b may be a size that allows the first and second engagement edges 13a and 13b to be inserted so as not to be greatly rattled.

また、底面３２ａには、第１のオーバハング部３４ａと第２のオーバハング部３４ｂとの間となる位置に嵌入突部３６が突設されている。嵌入突部３６は、図５の上方向から見た平面視で矩形状に形成されていると共に、図６（ａ）に示されるようにハウジング３１の側面視で、基部１３の長手方向他側となる小幅凹部３２ｅ側に、底面３２ａに向かうように後傾する斜面３６ａが形成され、端壁３２ｃ側では底面３２ａから直立に立ち上がる面が形成された台形断面形状を有する。 In addition, a fitting protrusion 36 projects from the bottom surface 32a at a position between the first overhang portion 34a and the second overhang portion 34b. The insertion protrusion 36 is formed in a rectangular shape in a plan view as viewed from above in FIG. 5, and the other side in the longitudinal direction of the base 13 in a side view of the housing 31 as shown in FIG. On the side of the narrow recess 32e to be formed, a slope 36a that is inclined backward toward the bottom surface 32a is formed, and on the end wall 32c side, a trapezoidal cross-sectional shape is formed that has a surface rising upright from the bottom surface 32a.

一方、端子片４の基部１３には、接続部１１とは相反する側から長手方向に所定の間隔で、第１の嵌合孔３７と第２の嵌合孔３８とがこの順に設けられている。各嵌合孔３７・３８は、図５の上方向から見た平面視で嵌入突部３６よりは大きく開口する矩形状に形成されている。 On the other hand, the base portion 13 of the terminal piece 4 is provided with a first fitting hole 37 and a second fitting hole 38 in this order at a predetermined interval in the longitudinal direction from the side opposite to the connection portion 11. Yes. Each fitting hole 37 and 38 is formed in the rectangular shape opened more largely than the fitting protrusion 36 in planar view seen from the upper direction of FIG.

次に、端子片４をハウジング３１に組み付ける要領を以下に説明する。先ず、図５の矢印Ｃに示されるように、端子片４を、基部１３からハウジング３１の凹部３２に入れるように、開口３２ｄから底面３２ａに向けて挿入する。なお、第１の係合縁部１３ａにおける基部１３の長手方向に対する長さ（図５の距離ａ）が第１及び第２のオーバハング部３４ａ・３４ｂの間隔（図５の距離ｂ）よりも少しだけ短くなるように設定されていると共に、第１及び第２の係合縁部１３ａ・１３ｂの間隔（図５の距離ｃ）が第２のオーバハング部３４ｂの長さ（図５の距離ｄ）よりも少しだけ長くなるように設定されている。また、小幅凹部３２ｅは、ケーブル２２が結合された状態の接続部１１を受容し得る大きさに形成されている。 Next, the procedure for assembling the terminal piece 4 to the housing 31 will be described below. First, as shown by an arrow C in FIG. 5, the terminal piece 4 is inserted from the opening 32 d toward the bottom surface 32 a so as to enter the recess 32 of the housing 31 from the base portion 13. Note that the length of the first engagement edge portion 13a in the longitudinal direction of the base portion 13 (distance a in FIG. 5) is slightly smaller than the distance between the first and second overhang portions 34a and 34b (distance b in FIG. 5). The distance between the first and second engagement edge portions 13a and 13b (distance c in FIG. 5) is the length of the second overhang portion 34b (distance d in FIG. 5). It is set to be slightly longer than. Further, the narrow recess 32e is formed to have a size that can receive the connecting portion 11 in a state where the cable 22 is coupled.

これにより、矢印Ｃの方向となる上面視で、第１及び第２の係合縁部１３ａ・１３ｂと胴部１３ｃとによる凹形状部分により第１のオーバハング部３４ａが受容され、第２の係合縁部１３ｂによる凸形状部分が、側壁３２ｂにおける両オーバハング部３４ａ・３４ｂ間の凹形状部分により受容され、第１の係合縁部１３ａが、側壁３２ｂにおける第１のオーバハング部３４ａと小幅凹部３２ｅとの間の部分により受容される。 As a result, the first overhang portion 34a is received by the concave portion formed by the first and second engagement edge portions 13a and 13b and the body portion 13c in a top view in the direction of the arrow C, and the second engagement. The convex portion formed by the edge portion 13b is received by the concave portion between the overhang portions 34a and 34b in the side wall 32b, and the first engagement edge portion 13a is connected to the first overhang portion 34a and the small-width concave portion in the side wall 32b. 32e is received by the part between.

このように、基部１３の外形と凹部３２の内壁の形状とが互いに補完的形状に形成されていることから、基部１３を凹部３２に上記矢印Ｃの方向に挿入することにより、基部１３が底面３２ａに載置される。底面３２ａに基部１３が載置され、第１の係合縁部１３ａが第１及び第２のオーバハング部３４ａ・３４ｂ間に位置した状態で、第１の嵌合孔３７に嵌入突部３６が嵌入するように第１の嵌合孔３７と嵌入突部３６との位置関係が設定されている。これにより、嵌入突部３６が基部１３の下面に突き当たって基部１３を押し上げてしまうことが回避され、第２の係合縁部１３ｂが底面３２ａから浮き上がることが防止され、基部１３が底面３２ａに載置状態になる。 Thus, since the outer shape of the base 13 and the shape of the inner wall of the recess 32 are complementary to each other, the base 13 is inserted into the recess 32 in the direction of the arrow C, so that the base 13 is 32a. With the base 13 placed on the bottom surface 32a and the first engagement edge 13a positioned between the first and second overhang portions 34a and 34b, the fitting protrusion 36 is inserted into the first fitting hole 37. The positional relationship between the first fitting hole 37 and the fitting protrusion 36 is set so as to be fitted. This prevents the fitting protrusion 36 from abutting against the lower surface of the base portion 13 and pushing up the base portion 13, preventing the second engagement edge portion 13 b from floating from the bottom surface 32 a, and the base portion 13 to the bottom surface 32 a. It will be placed.

この底面３２ａに基部１３が載置された状態により、ハウジング３１に対して端子片４が組み付け準備状態になる。この組み付け準備状態では、第１の係合縁部１３ａが第１の係合溝３５ａに、第２の係合縁部１３ｂが第２の係合溝３５ｂにそれぞれ対向して位置する。 With the base 13 placed on the bottom surface 32 a, the terminal piece 4 is ready for assembly with respect to the housing 31. In this assembly preparation state, the first engagement edge 13a is positioned opposite to the first engagement groove 35a, and the second engagement edge 13b is positioned opposite to the second engagement groove 35b.

次に、組み付け準備状態から、端子片４を図６の矢印Ｄにより示される前側にスライドさせることにより、第１の係合縁部１３ａが第１の係合溝３５ａに、第２の係合縁部１３ｂが第２の係合溝３５ｂにそれぞれ差し込まれる。各係合溝３５ａ・３５ｂのスライド方向に相反する側は、上縁部において斜め上方に向かうように形成された斜面によりそれぞれ拡開されている。スライド時に、基部１３における両嵌合孔３７・３８間の部分が嵌入突部３６を一旦乗り越えるため、その影響により各係合縁部１３ａ・１３ｂが底面３２ａから多少浮いた状態になる虞がある。それに対して、各係合溝３５ａ・３５ｂの上記拡開部分により各係合縁部１３ａ・１３ｂがガイドされるため、係合縁部１３ａ・１３ｂを各係合溝３５ａ・３５ｂに何等問題無く差し込むことができる。 Next, when the terminal piece 4 is slid to the front side indicated by the arrow D in FIG. 6 from the assembly preparation state, the first engagement edge portion 13a is engaged with the first engagement groove 35a in the second engagement. The edge portion 13b is inserted into the second engagement groove 35b. The opposite sides of the engaging grooves 35a and 35b in the sliding direction are expanded by slopes formed so as to extend obliquely upward at the upper edge portion. At the time of sliding, the portion between the fitting holes 37 and 38 in the base portion 13 temporarily gets over the fitting protrusion 36, and therefore, the engagement edge portions 13a and 13b may be slightly lifted from the bottom surface 32a due to the influence thereof. . On the other hand, since the engagement edge portions 13a and 13b are guided by the expanded portions of the engagement grooves 35a and 35b, the engagement edge portions 13a and 13b can be inserted into the engagement grooves 35a and 35b without any problem. Can be plugged in.

また、嵌入突部３６は嵌入状態の第１の嵌合孔３７にスライド方向に相反する側に係合するが、上述したように嵌入突部３６には端子片４の上記スライド方向に相反する側（小幅凹部３２ｅ側）に、底面３２ａに向けて傾斜する斜面３６ａが形成されている。これにより、第１の嵌合孔３７の縁は斜面３６ａ上を移動し得るため、大きな抵抗を受けることなく端子片４をスライドさせることができる。 Further, the fitting protrusion 36 engages with the first fitting hole 37 in the fitting state on the side opposite to the sliding direction, but as described above, the fitting protrusion 36 is opposite to the sliding direction of the terminal piece 4. On the side (the narrow recess 32e side), an inclined surface 36a that is inclined toward the bottom surface 32a is formed. Thereby, since the edge of the 1st fitting hole 37 can move on the slope 36a, the terminal piece 4 can be slid without receiving big resistance.

なお、嵌入突部３６に斜面３６ａを設けただけでも上記スライド時の抵抗感を無くす効果を有するが、本図示例では、図８（ａ）に示されるように第１の嵌合孔３７の下側の縁であって上記スライド方向に相反する側（接続部１１側）にも角を斜めに落とした面取り部３７ａが形成されている。これにより、斜面３６ａに面取り部３７ａが対峙するようになり、スライド時に斜面３６ａに面取り部３７ａが乗り上げ易くなり、端子片４をより円滑にスライドさせることができる。なお、斜面３６ａ及び面取り部３７ａの形状としては、図示例では平面からなる斜面としたが、例えば図８（ｂ）に示されるように、上記斜面３６ａに代えて円弧状断面等の曲面３６ｂであってもよい。 In addition, although it has the effect which eliminates the feeling of resistance at the time of the slide only by providing the slope 36a in the insertion protrusion 36, in this illustrated example, as shown in FIG. A chamfered portion 37a is formed on the lower edge and on the side opposite to the sliding direction (on the side of the connecting portion 11) with the corners obliquely dropped. Thereby, the chamfered portion 37a comes to face the inclined surface 36a, and the chamfered portion 37a can easily ride on the inclined surface 36a at the time of sliding, and the terminal piece 4 can be slid more smoothly. The shape of the inclined surface 36a and the chamfered portion 37a is a flat inclined surface in the illustrated example. However, as shown in FIG. 8B, for example, a curved surface 36b such as an arc-shaped cross section is used instead of the inclined surface 36a. There may be.

底面３２ａに基部１３が載置状態の端子片４を図６・図７の矢印Ｂで示される前側にスライドさせることにより、第１の嵌合孔３７が嵌入突部３６を乗り越えた後に、第２の嵌合孔３８が嵌入突部３６の位置まで移動してくる。 By sliding the terminal piece 4 with the base portion 13 placed on the bottom surface 32a to the front side indicated by the arrow B in FIGS. 6 and 7, after the first fitting hole 37 gets over the fitting protrusion 36, The second fitting hole 38 moves to the position of the fitting protrusion 36.

図９（ａ）及び図１０に示されるように、第２の嵌合孔３８に嵌入突部３６が嵌入した状態で、端子片４がハウジング３１に位置決めされる。この位置決め状態では、図９（ｂ）に併せて示されるように第１のオーバハング部３４ａによる第1の係合溝３５ａに第１の係合縁部１３ａが十分に差し込まれると共に、図９（ｃ）に併せて示されるように第２のオーバハング部３４ｂによる第２の係合溝３５ｂに第２の係合縁部１３ｂが十分に差し込まれるため、基部１３すなわち端子片４がハウジング３１の上方（開口３２ｄ側）に対して抜け止めされる。本実施形態では、各係合縁部１３ａ・１３ｂを基部１３の左右の一対設けており、対応するオーバハング部３４ａ・３４ｂもそれぞれ左右一対設けられており、基部１３の左右に係合部位が配置されているため、基部１３の左右方向の揺動が防止される。これにより、第２の嵌合孔３８への嵌入突部３６の嵌入状態が確実に保持され、ハウジング３１に対する基部１３の位置決め状態が確実に保持される。 As shown in FIGS. 9A and 10, the terminal piece 4 is positioned on the housing 31 in a state where the fitting protrusion 36 is fitted in the second fitting hole 38. In this positioning state, as shown in FIG. 9B, the first engagement edge portion 13a is sufficiently inserted into the first engagement groove 35a by the first overhang portion 34a, and FIG. c), the second engagement edge portion 13b is sufficiently inserted into the second engagement groove 35b formed by the second overhang portion 34b, so that the base portion 13, that is, the terminal piece 4 is located above the housing 31. It is prevented from coming off with respect to (opening 32d side). In the present embodiment, a pair of left and right engagement edges 13a and 13b are provided on the base 13, and a pair of corresponding overhangs 34a and 34b are also provided on the left and right, respectively. Therefore, the base 13 is prevented from swinging in the left-right direction. Thereby, the fitting state of the fitting protrusion 36 in the second fitting hole 38 is reliably held, and the positioning state of the base 13 with respect to the housing 31 is reliably held.

なお、端子片４の前側へのスライドに対しては端壁３２ｃがストッパとして機能する。仮止め状態から端子片４を端壁３２ｃ側にスライドさせた際に、端子片４の反転部１４ａが図９（ａ）の二点鎖線で示されるように端壁３２ｃに当接する。端壁３２ｃに反転部１４ａが当接した位置においても、第２の嵌合孔３８に嵌入突部３６が嵌入した状態が保持されるようになっており、端子片４をスライドさせ過ぎて第２の嵌合孔３８から嵌入突部３６が外れてしまうことが防止される。 Note that the end wall 32c functions as a stopper for sliding the terminal piece 4 forward. When the terminal piece 4 is slid to the end wall 32c side from the temporarily fixed state, the reversing portion 14a of the terminal piece 4 contacts the end wall 32c as shown by a two-dot chain line in FIG. Even at the position where the reversing portion 14a is in contact with the end wall 32c, the state in which the fitting protrusion 36 is fitted in the second fitting hole 38 is maintained, and the terminal piece 4 is slid excessively. The fitting protrusion 36 is prevented from being detached from the second fitting hole 38.

また、嵌入突部３６のスライド方向側（端壁３２ｃ側）は底面３２ａから垂直に立ち上がる壁面状に形成されており、端子片４の図６の後方（小幅凹部３２ｅ側）への変位に対しては、第２の嵌合孔３８の内周面が嵌入突部３６の上記壁面に当接するため、端子片４の後方への変位が規制される。なお、第２の嵌合孔３８の縁は、基部１３の主面に対して直交する壁面により形成されていてよい。このようにして、ハウジング３１に端子片４が位置決めかつ固定された状態に組み付けられて、コネクタ３３が構成される。 Moreover, the sliding direction side (end wall 32c side) of the insertion protrusion 36 is formed in the shape of the wall surface which stands | starts up perpendicularly | vertically from the bottom face 32a, and with respect to the displacement to the back (small-width recessed part 32e side) of FIG. As a result, the inner peripheral surface of the second fitting hole 38 abuts against the wall surface of the fitting projection 36, so that the rearward displacement of the terminal piece 4 is restricted. The edge of the second fitting hole 38 may be formed by a wall surface orthogonal to the main surface of the base portion 13. In this way, the connector 33 is configured by assembling the terminal piece 4 to the housing 31 in a state where the terminal piece 4 is positioned and fixed.

なお、上記第１実施形態では、第１の係合縁部１３ａの他に第２の係合縁部１３ｂを設けて、基部１３の底面３２ａからの浮き上がりを確実に防止するようにしたが、第１の係合縁部１３ａのみであってもよい。例えば、第１の係合縁部１３ａを第２の嵌合孔３８の略側方位置で長手方向に延在するように配設することにより、第２の嵌合孔３８の近傍における基部１３の浮き上がりが抑制されるため、ハウジング３１に対して端子片４が好適に抜け止めされる。 In the first embodiment, the second engagement edge 13b is provided in addition to the first engagement edge 13a to reliably prevent the base 13 from lifting from the bottom surface 32a. Only the first engagement edge 13a may be used. For example, the base 13 in the vicinity of the second fitting hole 38 is disposed by extending the first engaging edge 13 a so as to extend in the longitudinal direction at a substantially lateral position of the second fitting hole 38. Therefore, the terminal piece 4 is preferably prevented from coming off from the housing 31.

また、第１及び第２の係合縁部１３ａ・１３ｂが、基部１３の長手方向について第２の嵌合孔３８に対して異なる側に配置されている。図示例では、第２の係合縁部１３ｂを形成する拡幅部分が、基部１３の長手方向に対して第２の嵌合孔３８と重なるように延在しているが、第２の係合縁部１３ｂにおける第２のオーバハング部３４ｂと係合する部分は、第２の嵌合孔３８に対して第１の係合縁部１３ａとは基部１３の長手方向について相反する側（異なる側）に位置している。これにより、第２の嵌合孔３８に嵌入突部３６が嵌入した位置決め状態では、その嵌入部位に対して、両係合縁部１３ａ・１３ｂと両オーバハング部３４ａ・３４ｂとの各係合位置が互いに異なる側すなわち両側に位置するため、基部１３において、第２の嵌合孔３８を設けた部分の浮き上がりに対して両側で押さえ付けることから、基部１３の長手方向に対する位置決め状態が確実に保持される。 Further, the first and second engaging edge portions 13 a and 13 b are arranged on different sides with respect to the second fitting hole 38 in the longitudinal direction of the base portion 13. In the illustrated example, the widened portion forming the second engagement edge 13b extends so as to overlap the second fitting hole 38 with respect to the longitudinal direction of the base 13, but the second engagement The portion of the edge portion 13b that engages with the second overhang portion 34b is opposite to the first engagement edge portion 13a with respect to the second fitting hole 38 in the longitudinal direction of the base portion 13 (different side). Is located. Thereby, in the positioning state in which the fitting projection 36 is fitted in the second fitting hole 38, the respective engagement positions of both the engagement edge portions 13a and 13b and the both overhang portions 34a and 34b with respect to the insertion portion. Are positioned on different sides, that is, on both sides, the base 13 is pressed against the lift of the portion where the second fitting hole 38 is provided, so that the positioning of the base 13 in the longitudinal direction is reliably maintained. Is done.

このようにしてハウジング３１に端子片４が組み付けられたコネクタ３３は、例えば図１１に示されるようにコネクタハウジング４１に組み付けられる。コネクタハウジング４１の形状は、使用される部位に応じて種々の形状となり、図示例は一例である。 The connector 33 in which the terminal piece 4 is assembled to the housing 31 in this way is assembled to the connector housing 41 as shown in FIG. 11, for example. The shape of the connector housing 41 has various shapes depending on the part to be used, and the illustrated example is an example.

コネクタハウジング４１には、ハウジング３１を長手方向（図の矢印Ｅ方向）に挿入可能であり、かつ挿入方向端が閉塞された保持溝４２が形成されている。保持溝４２は、ハウジング３１を受容する矩形断面形状部分４２ａと、コネクタ３３においてハウジング３１の上方に突出する接触部４ａを外方に突出可能にするべく、ハウジング３１の幅よりも狭くされているが、接触部４ａの幅よりも広いスリット４２ｂとによる凸状断面形状に形成されている。これにより、保持溝４２に挿入された状態のハウジング３１はスリット４２ｂ側となる上方に対して抜け止めされる。 The connector housing 41 is formed with a holding groove 42 in which the housing 31 can be inserted in the longitudinal direction (the direction of arrow E in the figure) and the end in the insertion direction is closed. The holding groove 42 is made narrower than the width of the housing 31 so that the rectangular cross-section portion 42 a that receives the housing 31 and the contact portion 4 a that protrudes above the housing 31 in the connector 33 can protrude outward. However, it is formed in the convex cross-sectional shape by the slit 42b wider than the width | variety of the contact part 4a. As a result, the housing 31 inserted into the holding groove 42 is prevented from coming off from the upper side on the slit 42b side.

また、コネクタ３３のハウジング３１の両側面にはそれぞれ側方に突出する係合突部４３が設けられており、保持溝４２における矩形断面形状部分４２ａの対応する両内側面には係合凹部４４がそれぞれ設けられている。保持溝４２の矩形断面形状部分４２ａに挿入されたハウジング３１が所定位置に達した際に係合凹部４４に係合突部４３が突入して互いに係合することにより、ハウジング３１は挿入方向反対側に対して抜け止めされる。 Engaging protrusions 43 projecting sideways are provided on both side surfaces of the housing 31 of the connector 33, and engaging recesses 44 are formed on both inner side surfaces of the holding groove 42 corresponding to the rectangular cross-section portion 42 a. Are provided. When the housing 31 inserted into the rectangular cross-section portion 42a of the holding groove 42 reaches a predetermined position, the engaging protrusion 43 enters the engaging recess 44 and engages with each other, so that the housing 31 is opposite to the insertion direction. It is secured against the side.

図１２は使用状態の一例を説明する部分側面図である。コネクタハウジング４１にコネクタ３３が組み付けられた状態で、例えば図の矢印に示されるように相手コネクタ４５をコネクタハウジング４１に積層状態に結合する等して、接触部４ａを相手コネクタ４５の相手端子２３に接触させる。 FIG. 12 is a partial side view for explaining an example of the usage state. In a state where the connector 33 is assembled to the connector housing 41, the contact portion 4a is connected to the mating terminal 23 of the mating connector 45 by, for example, coupling the mating connector 45 to the connector housing 41 in a stacked state as indicated by the arrows in the figure. Contact.

図１３は、本発明が適用された第２実施形態を示す図９に対応する要部破断斜視図であり、図１４（ａ）は図１３のXIVａ−XIVａ線に沿って破断して矢印方向に見た要部側断面図であり、図１４（ｂ）は端子片４の位置決め状態を示す図１４（ａ）に対応する図である。なお、上記と同様の部分については同一の符号を付してその詳しい説明を省略する。 FIG. 13 is a fragmentary perspective view corresponding to FIG. 9 showing a second embodiment to which the present invention is applied, and FIG. 14A is broken along the XIVa-XIVa line in FIG. FIG. 14B is a view corresponding to FIG. 14A showing a positioning state of the terminal piece 4. In addition, about the part similar to the above, the same code | symbol is attached | subjected and the detailed description is abbreviate | omitted.

この第２実施形態では、上記第２の係合縁部１３ｂに対応する第２の係合縁部１３ｄが基部１３の延出方向端から延出方向に左右一対の舌片状に延出するように形成されている。なお、この第２実施形態では、上記第１実施形態における胴部１３ｃが基部１３の延出端まで延長された形状であり、それに伴って、接触部４ａにおける反転部１４ａから接点部１４ｃ及び折り返し部１４ｄに至る部分は上記第１実施形態の同部分に対して幅が狭くなるように形成されている。 In the second embodiment, a second engagement edge 13d corresponding to the second engagement edge 13b extends from the end of the base 13 in the extending direction into a pair of left and right tongue pieces in the extending direction. It is formed as follows. In addition, in this 2nd Embodiment, the trunk | drum 13c in the said 1st Embodiment is the shape extended to the extension end of the base 13, and in connection with it, from the inversion part 14a in the contact part 4a, the contact part 14c and folding | turning back The portion reaching the portion 14d is formed so as to be narrower than the same portion of the first embodiment.

側壁３２ｂの端壁３２ｃ側には上記第２のオーバハング部３４ｂに対応する第２のオーバハング部３４ｃが形成されている。底面３２ａと第２のオーバハング部３４ｃとの間には第２の係合溝３５ｃが形成されている。これら第２のオーバハング部３４ｃ及び第２の係合溝３５ｃは、上記第１実施形態に対して配設された位置が異なるだけで、第１実施形態における第２のオーバハング部３４ｂ及び第２の係合溝３５ｂと同一の形状であってよい。 A second overhang portion 34c corresponding to the second overhang portion 34b is formed on the side wall 32b on the end wall 32c side. A second engagement groove 35c is formed between the bottom surface 32a and the second overhang portion 34c. The second overhang portion 34c and the second engagement groove 35c are different from each other only in the position of the second overhang portion 34c and the second engagement groove 35c. The shape may be the same as that of the engaging groove 35b.

このように構成された第２実施形態においても、端子片４を図６及び図７の仮止め状態から矢印Ｄに示される向きにスライドさせることにより、上記第１実施形態と同様に第１の係合縁部１３ａが第１の係合溝３５ａに差し込まれると共に、端壁３２ｃに設けられた第２の係合溝３５ｃに第２の係合縁部１３ｄが突入するように差し込まれる。上記第１実施形態では、基部１３のスライド時に、基部１３における両嵌合孔３７・３８間の部分が嵌入突部３６を一旦乗り越える際に各係合縁部１３ａ・１３ｂが底面３２ａから多少浮いた状態になる虞があるのに対して、第２の係合縁部１３ｄが上記両嵌合孔３７・３８間の部分から離れた部位でありかつ離れる向きに延出していることから、上記乗り越える際の浮き上がりが抑制され、第２の係合縁部１３ｄを第２の係合溝３５ｃに容易に差し込むことができる。 Also in the second embodiment configured as described above, the terminal piece 4 is slid in the direction indicated by the arrow D from the temporarily fixed state of FIGS. The engagement edge portion 13a is inserted into the first engagement groove 35a, and the second engagement edge portion 13d is inserted into the second engagement groove 35c provided in the end wall 32c. In the first embodiment, when the base portion 13 is slid, the engagement edge portions 13a and 13b are slightly lifted from the bottom surface 32a when the portion between the fitting holes 37 and 38 in the base portion 13 once gets over the fitting protrusion 36. The second engagement edge 13d is a part away from the part between the two fitting holes 37 and 38 and extends away from the part. Lifting when getting over is suppressed, and the second engagement edge 13d can be easily inserted into the second engagement groove 35c.

なお、図示例では、第２のオーバハング部３４ｃは、両側壁３２ｂ間に亘って連続するように端壁３２ｃと一体化されているが、各第２の係合縁部１３ｄが差し込まれて係合可能な第２の係合縁部１３ｄが設けられていればよく、両側壁３２ｂ間の中間部で分断されていてもよい。また、各嵌合孔３７・３８と嵌入突部３６との関係は第１実施形態と同じであり、第２の嵌合孔３８に嵌入突部３６が嵌入した位置決め状態で、第１実施形態と同様にハウジング３１に端子片４が固定状態に組み付けられる。この第２実施形態においても、上記第１実施形態と同様の作用効果を奏し得る。 In the illustrated example, the second overhang portion 34c is integrated with the end wall 32c so as to continue between both side walls 32b. However, each second engagement edge portion 13d is inserted into the second overhang portion 34c. It is only necessary to provide a second engaging edge portion 13d that can be joined, and it may be divided at an intermediate portion between both side walls 32b. The relationship between each fitting hole 37 and 38 and the fitting projection 36 is the same as that of the first embodiment. In the positioning state in which the fitting projection 36 is fitted into the second fitting hole 38, the first embodiment. Similarly, the terminal piece 4 is assembled to the housing 31 in a fixed state. Also in the second embodiment, the same operational effects as those of the first embodiment can be obtained.

以上、本発明を、その好適実施形態の実施例について説明したが、当業者であれば容易に理解できるように、本発明はこのような実施例に限定されるものではなく、本発明の趣旨を逸脱しない範囲で適宜変更可能である。例えば、上記実施形態では端子片４をケーブル２２側とは反対となる前側にスライドさせたが、ケーブル２２側となる後側にスライドさせるようにしてもよい。この場合には、第１のオーバハング部３４ａに第２の係合縁部１３ｂが差し込まれる第２の係合溝３５ｂを設け、第２のオーバハング部３４ｂには係合溝を設けずに、ハウジング３１の小幅凹部３２ｅを形成する部分に第１の係合縁部１３ａが差し込まれる第１の係合溝３５ａを設ければよく、また、適所に設けた斜面や面取り部も反対側に設けることで対応し得る。 Although the present invention has been described with reference to the preferred embodiments, the present invention is not limited to such embodiments and can be easily understood by those skilled in the art. As long as it does not deviate from the above, it can be appropriately changed. For example, in the above embodiment, the terminal piece 4 is slid to the front side opposite to the cable 22 side, but may be slid to the rear side to be the cable 22 side. In this case, the second overhang portion 34a is provided with a second engagement groove 35b into which the second engagement edge portion 13b is inserted, and the second overhang portion 34b is not provided with an engagement groove. The first engagement groove 35a into which the first engagement edge 13a is inserted may be provided in the portion of the 31 where the small-width recess 32e is formed, and a slope or a chamfered portion provided at an appropriate position is also provided on the opposite side. Can respond.

また、上記実施形態に示した構成要素は必ずしも全てが必須なものではなく、本発明の趣旨を逸脱しない限りにおいて適宜取捨選択することが可能である。例えば、第１及び第２実施形態では、基部１３の長手方向に各一対の係合縁部１３ａ・１３ｂ（１３ａ・１３ｃ）を設けたが、それぞれいずれか一方、更に左右のいずれか一方となる１箇所だけを所定の縁部として設けてもよい。所定の縁部を１箇所とする場合には、対応するオーバハング部を、第２の嵌合孔３８の近傍であって、基部１３の中央付近まで大きく覆い被さるように設けることにより、基部１３の浮き上がりを抑制し得るようにすればよい。 In addition, all the components shown in the above embodiment are not necessarily essential, and can be appropriately selected without departing from the gist of the present invention. For example, in the first and second embodiments, each pair of engagement edge portions 13a and 13b (13a and 13c) is provided in the longitudinal direction of the base portion 13, but either one or both of the left and right sides are provided. Only one place may be provided as a predetermined edge. In the case where the predetermined edge portion is provided at one place, the corresponding overhang portion is provided so as to largely cover the vicinity of the second fitting hole 38 and the vicinity of the center of the base portion 13. What is necessary is just to be able to suppress a lift.
