本発明は、端末接続構造に関する。 The present invention relates to a terminal connection structure.

コントロールケーブルのような長尺部材を相手部材に連結する構造の１つとして、特許文献１には、コントロールケーブルを連結する中継機構が開示されている。図８に示されるように、特許文献１の中継機構１００は、中継機構１００に対して一方の方向に延びるコントロールケーブル１０１ａと、他方の方向に延びるコントロールケーブル１０１ｂとを中継接続している。具体的には、一方のコントロールケーブル１０１ａのインナーケーブル１０２ａのケーブルエンド１０３がジョイント部材１０４の一端（図８中、左側）に係止される。他方のコントロールケーブル１０１ｂのインナーケーブル１０２ｂは、アタッチメント部材１０５に係止され、アタッチメント部材１０５がジョイント部材１０４に形成された挿通孔１０６に挿入されてジョイント部材１０４に取り付けられる。 As one structure for connecting a long member such as a control cable to a mating member, Patent Document 1 discloses a relay mechanism for connecting a control cable. As shown in FIG. 8, the relay mechanism 100 of Patent Document 1 relay-connects a control cable 101 a extending in one direction to the relay mechanism 100 and a control cable 101 b extending in the other direction. Specifically, the cable end 103 of the inner cable 102a of one control cable 101a is locked to one end (left side in FIG. 8) of the joint member 104. The inner cable 102 b of the other control cable 101 b is locked to the attachment member 105, and the attachment member 105 is inserted into the insertion hole 106 formed in the joint member 104 and attached to the joint member 104.

ジョイント部材１０４の挿通孔１０６に挿入されるアタッチメント部材１０５には、ばね部材１０７が設けられ、ばね部材１０７は部分的に周方向に広がった板ばね１０８を備えている。ばね部材１０７は、ジョイント部材１０４の挿通孔１０６に挿入されるときに弾性変形し、ジョイント部材１０４の内部に入った後に、ばね部材１０７の板ばね１０８が外向きに広がって、アタッチメント部材１０５がジョイント部材１０４に連結される。ばね部材１０７は、図９に示されるように、アタッチメント部材１０５の先端から圧入されて、アタッチメント部材１０５の軸状の部位のうち、径が細くなった取付部位１０９に嵌合されて取り付けられる。ばね部材１０７は、部分的に周方向に広がった板ばね１０８以外に、板ばね１０８の間に、取付部位１０９の軸方向両側に形成された段差１０９ａ、１０９ｂの部分に挟み込まれる規制部１１０が設けられており、ジョイント部材１０４の挿通孔１０６にアタッチメント部材１０５が挿入されるときに、ばね部材１０７のアタッチメント部材１０５に対する軸方向の移動を規制している。 The attachment member 105 inserted into the insertion hole 106 of the joint member 104 is provided with a spring member 107, and the spring member 107 includes a leaf spring 108 that partially extends in the circumferential direction. The spring member 107 is elastically deformed when inserted into the insertion hole 106 of the joint member 104, and after entering the inside of the joint member 104, the leaf spring 108 of the spring member 107 spreads outward, and the attachment member 105 is It is connected to the joint member 104.

しかしながら、アタッチメント部材１０５の先端からばね部材１０７を圧入する際に、アタッチメント部材１０５とばね部材１０７の軸心とが傾斜した状態で圧入した場合など、圧入の仕方によっては、規制部１１０が塑性変形して、本来外側には広がっていない規制部１１０が外側に広がった状態となってしまい、取付部位１０９の段差１０９ａ、１０９ｂ（特に段差１０９ｂ）とうまく係合しない場合がある。このような場合、アタッチメント部材１０５をジョイント部材１０４の挿通孔１０６へ挿入する時に、ばね部材１０７がアタッチメント部材１０５の取付部位１０９に対して軸方向（図８中、右側）にずれてしまい、アタッチメント部材１０５とジョイント部材１０４との連結がうまくいかず、ばね部材１０７を後加工、修正加工して取り付ける必要となる場合があるため、より確実にばね部材１０７とアタッチメント部材１０５とを取り付けることができる構造が望まれている。 However, when the spring member 107 is press-fitted from the tip of the attachment member 105, the restricting portion 110 may be plastically deformed depending on the method of press-fitting, such as when the attachment member 105 and the shaft center of the spring member 107 are inclined. As a result, the restricting portion 110 that does not originally spread outward may be expanded outward, and may not engage well with the steps 109a and 109b (particularly the step 109b) of the attachment site 109. In such a case, when the attachment member 105 is inserted into the insertion hole 106 of the joint member 104, the spring member 107 is displaced in the axial direction (right side in FIG. 8) with respect to the attachment portion 109 of the attachment member 105. The connection between the member 105 and the joint member 104 is not successful, and it may be necessary to attach the spring member 107 by post-processing or correction processing. Therefore, the spring member 107 and the attachment member 105 can be attached more reliably. A structure is desired.

そこで、本発明はかかる問題点に鑑みて、弾性片と規制部を有した、端末部材本体に嵌合される嵌合子が、端末部材本体に対して軸方向に移動することを規制することができる端末接続構造の提供を目的とする。 Therefore, in view of such a problem, the present invention can regulate the movement of the fitting member fitted to the terminal member main body having the elastic piece and the restricting portion in the axial direction with respect to the terminal member main body. The purpose is to provide a terminal connection structure that can be used.

また、前記連結部が、前記複数の規制部のうち、前記挿入部の基端側の端部同士を連結することが好ましい。 Moreover, it is preferable that the said connection part connects the edge parts of the base end side of the said insertion part among these control parts.

また、前記長尺部材がコントロールケーブルであり、前記端末部材本体の取付部が、前記挿入部よりも大きい柱状に形成され、前記取付部に、前記コントロールケーブルのインナーケーブルのケーブルエンドが係止される係止凹部が形成され、前記係止凹部は、前記取付部のうち、前記挿入部が延びる側の端面において開口し、前記連結部が前記取付部の端面に係合するとともに、前記連結部が前記取付部の端面における係止凹部の開口幅よりも長く形成されていることが好ましい。 Further, the long member is a control cable, the attachment portion of the terminal member main body is formed in a column shape larger than the insertion portion, and the cable end of the inner cable of the control cable is locked to the attachment portion. A locking recess is formed at the end of the mounting portion on the side where the insertion portion extends, and the connecting portion engages with an end surface of the mounting portion, and the connecting portion Is preferably formed longer than the opening width of the locking recess in the end face of the mounting portion.

It is inserted into the insertion opening 3 a of the mating member 3 and connected to the mating member 3. The terminal connection structure 1 is used to connect the mating member 3 and the long member 2 via the terminal member 4. For example, a vehicle seat operation device for connecting a plurality of control cables to each other, a fuel lid, or the like The present invention can be applied to an opening / closing mechanism of a trunk and an opening / closing mechanism of a trunk. Moreover, it is possible to apply also to uses other than for vehicles.

長尺部材２は、所定の長さを有し、端末部材４を介して離れた地点間を接続するために用いられる。また、長尺部材２は、たとえば、一方側に加えられた操作力を、離れた位置にある他方側へと伝達するために用いることができる。長尺部材２は、離れた地点を接続するものであれば、特に限定されないが、たとえば、図１および図２に示すように、インナーケーブル２２ａ、２２ｂとアウターケーシング２３ａ、２３ｂとを備えたコントロールケーブルや、操作力を伝達するロッド状の部材であっても構わない。なお、本実施形態では、コントロールケーブルのインナーケーブル２２ａ、２２ｂの一端側の端末２１ａ、２１ｂが端末部材４に取り付けられているが、アウターケーシング２３ａ、２３ｂの端末が端末部材４に取り付けられても構わない。また、図１では、端末部材４には、長尺部材２が２つ取り付けられているが、端末部材４に取り付けられる長尺部材２の数は特に限定されず、１つでも、３つ以上であってもよい。 The elongate member 2 has a predetermined length and is used to connect points separated from each other via the terminal member 4. Moreover, the elongate member 2 can be used in order to transmit the operating force applied to one side to the other side in the distant position, for example. The long member 2 is not particularly limited as long as it connects distant points. For example, as shown in FIGS. 1 and 2, a control including inner cables 22a and 22b and outer casings 23a and 23b. It may be a cable or a rod-shaped member that transmits operating force. In the present embodiment, the terminals 21 a and 21 b on one end side of the inner cables 22 a and 22 b of the control cable are attached to the terminal member 4, but even if the terminals of the outer casings 23 a and 23 b are attached to the terminal member 4.

If the other party member 3 can connect the terminal member 4 according to the use of the terminal connection structure 1, the shape and structure will not be limited. The insertion opening 3a can be appropriately changed according to the shape of the terminal member 4 to be inserted. As will be described later, the elastic piece 61 of the fitting 6 of the terminal member 4 is inserted into the terminal member 4. When the elastic piece 61 spreads out after the end of the insertion of the terminal member 4 and the elastic piece 61 spreads out when it is inserted into the opening 3a and the end piece 4 is inserted, the elastic piece 61 is provided on the inner side of the insertion opening 3a. The terminal member 4 is sized to engage with the engaging portion 3 b and engage with the elastic piece 61 to prevent the terminal member 4 from coming out of the mating member 3.

The member 2 is connected by a mating member 3 (joint member). Although the connection structure between the mating member 3 and the terminal member 4 will be described later, in the case of this embodiment, when a pulling operation is applied to the other inner cable 22c, the mating member 3 (joint member) is connected to 2 The two long members 2 are configured to be pulled. More specifically, as shown in FIG. 1, the mating member 3 has the terminal member 4 connected to one end of the mating member 3 and the terminal 21 c of the other inner cable 22 c locked to the other end. It is slidably accommodated in a cylindrical joint case C.

As described above, such a relay mechanism can be applied to a vehicle seat operating device, for example. In this embodiment, one long member (outer casing 23c, inner cable 22c) and two long members 2 (outer casing 23a, inner cable 22a, outer casing 23b, inner cable 22b) are relayed. The connecting relay mechanism is shown. However, the present invention is not limited to such a structure, and may be applied to a relay mechanism that relay-connects one long member and one long member, such as an opening / closing mechanism of a fuel lid. And two long members may be connected.

It is attached. When the terminals 21a and 21b of the long member 2 are attached to the attachment portion 51 by engagement, the method for fixing the engagement is not particularly limited, but may be engaged from the outer peripheral side of the attachment portion 51, or the long member 2 may be engaged. When there is only one, the cavity is provided inside the insertion part 52 of the terminal member body 5, and the terminals 21 a and 21 b of the long member 2 are engaged with the attachment part 51 through the insertion part 52. May be. In this embodiment, as shown in FIGS. 3A and 3B, the attachment portion 51 of the terminal member body 5 is formed in a column shape larger than the insertion portion 52, and the control cable is connected to the attachment portion 51. A locking recess 51a for locking the cable ends (terminals 21a, 21b) of the inner cables 22a, 22b is formed. The locking recess 51a opens on the end surface 51b (see FIG. 3B) on the side from which the insertion portion 52 extends out of the both end surfaces of the mounting portion 51, shortens the axial length of the mounting portion 51, and The member body 5 is reduced in size and weight. As shown in FIGS. 3A and 3B, the locking recess 51 a is open to the outer peripheral side of the mounting portion 51 and the end surface 51 b. Ends 21a and 21b of the inner cables 22a and 22b are engaged with the locking recess 51a from the outer peripheral side of the mounting portion 51, and guide grooves 51c that guide the inner cables 22a and 22b when the inner cables 22a and 22b are mounted. The inner cables 22a and 22b are attached along the cable.

また、図３（ａ）および（ｂ）に示す端末部材本体５の形状は、あくまで一例であり、取付部５１と挿入部５２の大きさ（軸方向、軸周りの大きさ）は、特に限定されるものではない。また、係止凹部５１ａの形状も、図示した形状に限られず、長尺部材２の端末２１ａ、２１ｂの形状等に応じて適宜変更が可能である。また、本実施形態では、ガイド溝５１ｃは、図３（ａ）に示されるように、係止凹部５１ａから、取付部５１の周方向に沿って延びた後、取付部５１の軸方向に延びたものを示しているが、ガイド溝５１ｃの形状は、特に図示した形状に限定されるものではない。その他、長尺部材２の端末２１ａ、２１ｂの取付部５１への係合構造は、用いられる長尺部材２の本数や、端末２１ａ、２１ｂの形状や大きさ、端末部材本体５の形状や大きさに応じて適宜変更が可能であり、公知の係合構造を用いることができる。 Moreover, the shape of the terminal member main body 5 shown to FIG. 3 (a) and (b) is an example to the last, and the magnitude | size (axial direction and the magnitude | size around an axis) of the attaching part 51 and the insertion part 52 is especially limited. Is not to be done. Further, the shape of the locking recess 51a is not limited to the illustrated shape, and can be appropriately changed according to the shape of the terminals 21a and 21b of the long member 2. In the present embodiment, as shown in FIG. 3A, the guide groove 51 c extends from the locking recess 51 a along the circumferential direction of the mounting portion 51 and then extends in the axial direction of the mounting portion 51. However, the shape of the guide groove 51c is not particularly limited to the illustrated shape. In addition, the engagement structure of the long member 2 to the attachment portions 51 of the terminals 21a and 21b includes the number of the long members 2 used, the shapes and sizes of the terminals 21a and 21b, and the shapes and sizes of the terminal member main body 5. Changes can be made accordingly, and a known engagement structure can be used.

図２、図３（ａ）および（ｂ）に示されるように、取付部５１からは挿入部５２が取付部５１と同軸上に延びている。挿入部５２は、図１に示されるように、嵌合子６が嵌合され、相手部材３の挿入開口部３ａに挿入される部位である。挿入部５２は、嵌合子６を嵌合することができ、嵌合子６を嵌合した後に、相手部材３の挿入開口部３ａに挿入することができれば、その形状は特に限定されない。たとえば、挿入部５２は挿入開口部３ａに挿入しやすくするために、軸状に形成することができ、図３（ａ）および（ｂ）に示されるように、略円柱状に形成してもよいし、略角柱状に形成してもよいし、内部に空洞を有した略円筒状、略角筒状に形成してもよい。 As shown in FIGS. 2, 3 (a) and 3 (b), an insertion portion 52 extends coaxially with the attachment portion 51 from the attachment portion 51. As shown in FIG. 1, the insertion portion 52 is a portion into which the fitting 6 is fitted and inserted into the insertion opening 3 a of the mating member 3. The shape of the insertion portion 52 is not particularly limited as long as it can be fitted into the fitting 6 and can be inserted into the insertion opening 3 a of the mating member 3 after fitting the fitting 6. For example, the insertion portion 52 can be formed in a shaft shape so that it can be easily inserted into the insertion opening 3a, and can be formed in a substantially cylindrical shape as shown in FIGS. 3 (a) and 3 (b). Alternatively, it may be formed in a substantially prismatic shape, or may be formed in a substantially cylindrical shape or a substantially rectangular tube shape having a cavity inside.

挿入部５２は、端末部材本体５の先端側に位置する先端部位５２ａと、先端部位５２ａと軸方向で連続し、嵌合子６が嵌合される嵌合部位５２ｂとを有している。詳細は後述するが、嵌合部位５２ｂには、嵌合子６が嵌合するとともに、嵌合子６が軸方向に移動しないように、嵌合部位５２ｂの先端側（図３（ａ）および（ｂ）中、左側）と、基端側（取付部５１側。図３（ａ）および（ｂ）中、右側）に段部Ｓｔ１、Ｓｔ２が形成されている。段部Ｓｔ１、Ｓｔ２のうち、基端側の段部Ｓｔ２は、図２、図３（ａ）および（ｂ）に示されるように、挿入部５２の途中にあってもよいし、後述する他の実施形態（図７（ａ）および（ｂ）参照）のように、挿入部５２と取付部５１の境界部を段部Ｓｔ２としてもよい。 The insertion portion 52 includes a distal end portion 52a located on the distal end side of the terminal member main body 5, and a fitting portion 52b that is continuous with the distal end portion 52a in the axial direction and into which the fitting 6 is fitted. Although the details will be described later, the fitting portion 52b is fitted with the fitting 6 and the fitting portion 52b is not moved in the axial direction so that the distal end side of the fitting portion 52b (see FIGS. 3A and 3B). Steps St1 and St2 are formed on the left side) and the base end side (on the mounting portion 51 side, on the right side in FIGS. 3A and 3B). Of the stepped portions St1 and St2, the stepped portion St2 on the proximal end side may be in the middle of the insertion portion 52 as shown in FIG. 2, FIG. 3A and FIG. As in the embodiment (see FIGS. 7A and 7B), the boundary between the insertion portion 52 and the attachment portion 51 may be a stepped portion St2.

つぎに、挿入部５２に取り付けられる嵌合子６について説明する。嵌合子６は、挿入部５２に嵌合して取り付けられて、挿入部５２を挿入開口部３ａに挿入した後、端末部材４が、操作時などに挿入開口部３ａから抜け出ないようにする機能を有する。嵌合子６は、図４（ａ）〜（ｃ）に示されるように、複数の弾性片６１と、複数の弾性片６１の間で挿入部５２の軸方向に延びる複数の規制部６２と、複数の規制部６２を、挿入部５２の周方向で互いに連結する連結部６３とを備えている。嵌合子６は、図１に示されるように、端末部材本体５の挿入部５２の嵌合部位５２ｂに嵌合できるように、嵌合部位５２ｂの形状に対応した全体形状（略円筒形状）を呈し、嵌合部位５２ｂへの嵌合時や、挿入開口部３ａへの挿入時などに弾性変形可能なように、金属や合成樹脂など、所定の強度を有し、弾性変形可能な材料から構成されている。より詳細に説明すると、本実施形態の嵌合子６は、嵌合部位５２ｂの先端側（図４（ａ）、（ｃ）中、左側）において、弾性片６１および規制部６２が周方向で連結されて、略環状の基部６４を形成している。略環状の基部６４には、嵌合子６を挿入部５２の先端部位５２ａから嵌合する際に、基部６４が拡径可能なように、軸方向に沿ってスリットＳＬが設けられている。嵌合子６の挿入部５２への嵌合は、嵌合子６が挿入部５２から外れないように嵌め込まれるものであればよく、たとえば、図２に示されるように、嵌合子６の基端部側（図２中、右側）を挿入部５２の先端部位５２ａから、規制部６２や基部６４を外側に広げながら圧入して嵌め込み、嵌め込み後に規制部６２や基部６４が元の状態に復元することにより嵌合することができる。 Next, the fitting 6 attached to the insertion portion 52 will be described. The fitting 6 is fitted and attached to the insertion portion 52, and after the insertion portion 52 is inserted into the insertion opening 3a, the terminal member 4 is prevented from coming out of the insertion opening 3a during operation or the like. Have As shown in FIGS. 4A to 4C, the fitting 6 includes a plurality of elastic pieces 61, a plurality of restricting portions 62 that extend between the plurality of elastic pieces 61 in the axial direction of the insertion portion 52, and A plurality of restricting portions 62 are provided with a connecting portion 63 that connects the restricting portions 62 to each other in the circumferential direction of the inserting portion 52. As shown in FIG. 1, the fitting 6 has an overall shape (substantially cylindrical shape) corresponding to the shape of the fitting portion 52 b so that it can be fitted into the fitting portion 52 b of the insertion portion 52 of the terminal member body 5. It is made of an elastically deformable material having a predetermined strength, such as metal or synthetic resin, so that it can be elastically deformed when it is fitted to the fitting part 52b or inserted into the insertion opening 3a. Has been. More specifically, in the fitting 6 of this embodiment, the elastic piece 61 and the restricting portion 62 are connected in the circumferential direction on the distal end side (the left side in FIGS. 4A and 4C) of the fitting portion 52b. As a result, a substantially annular base 64 is formed. The substantially annular base 64 is provided with a slit SL along the axial direction so that the diameter of the base 64 can be expanded when the fitting 6 is fitted from the distal end portion 52 a of the insertion portion 52. The fitting of the fitting 6 to the insertion portion 52 may be performed as long as the fitting 6 is fitted so that it does not come off the insertion portion 52. For example, as shown in FIG. The side (the right side in FIG. 2) is inserted from the distal end portion 52a of the insertion portion 52 with the restricting portion 62 and the base portion 64 being outwardly expanded, and the restricting portion 62 and the base portion 64 are restored to the original state after the fitting. Can be fitted.

複数の弾性片６１は、図５（ａ）〜（ｃ）に示されるように、挿入開口部３ａへの挿入時に弾性変形して挿入開口部３ａに挿入され、挿入開口部３ａに挿入された後に広がり、相手部材３の内側係合部３ｂと係合する。弾性片６１が、相手部材３の内側係合部３ｂと係合することにより、嵌合子６が嵌合された端末部材本体５が、長尺部材２が操作されたときなどに相手部材３の挿入開口部３ａから抜け出ることが防止される。弾性片６１は、図４（ａ）、図５（ａ）〜（ｃ）に示されるように、基部６４から挿入部５２の基端側に向かって外側に広がって延びた板バネ状に形成され、複数の（２つの）弾性片６１が周方向でほぼ均等に離間するように設けられている。弾性片６１は、図５（ａ）に示されるように、挿入開口部３ａへの挿入時に、挿入開口部３ａの開口縁と当接するように外側に広がっており、図５（ｂ）に示されるように、挿入開口部３ａの開口縁と当接した後、挿入部５２を挿入開口部３ａにさらに押し込むことにより、外側に広がった弾性片６１が、挿入部５２の軸心方向に向かって内側に弾性変形して挿入開口部３ａに挿入される。挿入された後は、図５（ｃ）に示されるように、弾性変形した弾性片６１は元の状態に戻って外側に広がる。元の状態に戻った弾性片６１は、図５（ｃ）に示されるように、相手部材３の内側係合部３ｂと係合可能となり、端末部材４に取り付けられた長尺部材２が引き操作されても、端末部材本体５は、挿入開口部３ａから抜け出ることがない。そして、たとえば、図１において、図中左側のインナーケーブル２２ｃが左側に引き操作されると、相手部材３もジョイントケースＣ内を左側に移動する。相手部材３が左側に移動すると、弾性片６１が相手部材３の内側係合部３ｂと係合しているため、端末部材４も相手部材３とともに左側に移動する。これにより、図１中、右側の２つの長尺部材２（インナーケーブル２２ａ、２２ｂ）が操作される。 As shown in FIGS. 5A to 5C, the plurality of elastic pieces 61 are elastically deformed when inserted into the insertion opening 3a, inserted into the insertion opening 3a, and inserted into the insertion opening 3a. It spreads later and engages with the inner engagement portion 3b of the counterpart member 3. When the elastic member 61 engages with the inner engagement portion 3b of the mating member 3, the terminal member main body 5 fitted with the mating member 6 is brought into contact with the mating member 3 when the long member 2 is operated. It is prevented from coming out of the insertion opening 3a. As shown in FIGS. 4A and 5A to 5C, the elastic piece 61 is formed in a leaf spring shape that extends outward from the base portion 64 toward the base end side of the insertion portion 52. The plurality of (two) elastic pieces 61 are provided so as to be substantially evenly spaced in the circumferential direction. As shown in FIG. 5A, the elastic piece 61 spreads outward so as to contact the opening edge of the insertion opening 3a when inserted into the insertion opening 3a, as shown in FIG. 5B. As described above, after contacting the opening edge of the insertion opening 3 a, the insertion portion 52 is further pushed into the insertion opening 3 a, so that the elastic piece 61 spreading outward is directed toward the axial center of the insertion portion 52. It is elastically deformed inward and inserted into the insertion opening 3a. After the insertion, as shown in FIG. 5C, the elastically deformed elastic piece 61 returns to its original state and spreads outward. As shown in FIG. 5C, the elastic piece 61 that has returned to the original state can be engaged with the inner engagement portion 3 b of the counterpart member 3, and the long member 2 attached to the terminal member 4 is pulled. Even if operated, the terminal member main body 5 does not come out of the insertion opening 3a. For example, in FIG. 1, when the left inner cable 22c is pulled to the left in the drawing, the mating member 3 also moves to the left in the joint case C. When the counterpart member 3 moves to the left side, since the elastic piece 61 is engaged with the inner engagement portion 3b of the counterpart member 3, the terminal member 4 also moves to the left side together with the counterpart member 3. Thereby, the two long members 2 (inner cables 22a and 22b) on the right side in FIG. 1 are operated.

図４（ａ）〜（ｃ）に示した嵌合子６では、弾性片６１は、略環状の基部６４から直線的に延びたものを示しているが、挿入部５２の挿入開口部３ａへの挿入時に弾性変形し、挿入後は相手部材３の内側係合部３ｂと係合して、端末部材本体５が挿入開口部３ａから抜け出ることを防止することができるものであれば、その形状は特に限定されない。また、嵌合子６に設けられる弾性片６１の数は、端末部材本体５が相手部材３の挿入開口部３ａから抜け出ないように、弾性片６１が相手部材３の内側係合部３ｂと係合するものであれば、特に限定されるものではなく、図４（ａ）〜（ｃ）に示されるように２つであってもよいし、３つ以上であっても構わない。 In the fitting 6 shown in FIGS. 4A to 4C, the elastic piece 61 is linearly extended from the substantially annular base portion 64, but the insertion portion 52 is inserted into the insertion opening 3 a. If it is elastically deformed at the time of insertion and can be engaged with the inner engagement portion 3b of the mating member 3 after insertion to prevent the terminal member body 5 from coming out of the insertion opening 3a, its shape is There is no particular limitation. Further, the number of elastic pieces 61 provided in the fitting 6 is such that the elastic pieces 61 engage with the inner engagement portions 3b of the counterpart member 3 so that the terminal member main body 5 does not come out of the insertion opening 3a of the counterpart member 3. If it does, it will not specifically limit, Two may be sufficient as shown by Fig.4 (a)-(c), and three or more may be sufficient.

弾性片６１は、図５（ｂ）に示されるように、挿入部５２を挿入開口部３ａに挿入するときに、挿入開口部３ａの開口縁と当接しながら挿入されるため、弾性片６１は挿入開口部３ａの開口縁から挿入方向（図５中、左側）とは反対方向（図５中、右側）の反力を受ける。したがって、弾性片６１が受けた挿入方向とは反対方向の反力により、嵌合子６が挿入部５２に対して軸方向でずれないように、嵌合子６の軸方向両端が端末部材本体５と係合して嵌合子６の挿入部５２に対する軸方向の移動を規制する複数の規制部６２が設けられている。 As shown in FIG. 5B, the elastic piece 61 is inserted while contacting the opening edge of the insertion opening 3a when the insertion portion 52 is inserted into the insertion opening 3a. A reaction force in a direction opposite to the insertion direction (left side in FIG. 5) (right side in FIG. 5) is received from the opening edge of the insertion opening 3a. Therefore, both ends in the axial direction of the fitting 6 and the terminal member main body 5 are prevented so that the fitting 6 does not shift in the axial direction with respect to the insertion portion 52 due to a reaction force opposite to the insertion direction received by the elastic piece 61. A plurality of restricting portions 62 that are engaged to restrict the axial movement of the fitting 6 with respect to the insertion portion 52 are provided.

規制部６２は、図５（ａ）〜（ｃ）に示されるように、規制部６２の軸方向両端が端末部材本体５と係合しており、規制部６２の先端側の端部６２ａが、嵌合部位５２ｂの先端側の段差Ｓｔ１と係合し、規制部６２の基端側の端部６２ｂが、嵌合部位５２ｂの基端側の段差Ｓｔ２と係合する。これにより規制部６２は、挿入部５２が挿入開口部３ａへ挿入されるときには、規制部６２の基端側の端部６２ｂと嵌合部位５２ｂの基端側の段差Ｓｔ２とが係合して、嵌合子６が、挿入部５２に対して基端側に移動することを規制する。そして、挿入部５２が挿入開口部３ａに挿入された後に、長尺部材２の操作などにより、相手部材３の内側係合部３ｂと弾性片６１が係合すると、嵌合子６は内側係合部３ｂからの反力により、嵌合子６を、挿入部５２に対して挿入部５２の先端方向に移動させる方向の力が加わるが、規制部６２の先端側の端部６２ａと嵌合部位５２ｂの先端側の段差Ｓｔ１とが係合して、嵌合子６が、挿入部５２に対して先端側に移動することを規制する。 As shown in FIGS. 5A to 5C, the restricting portion 62 has both end portions in the axial direction of the restricting portion 62 engaged with the terminal member main body 5, and the end portion 62 a on the distal end side of the restricting portion 62 is The engagement portion 52b is engaged with the step St1 on the distal end side, and the proximal end 62b of the restriction portion 62 is engaged with the step St2 on the proximal end side of the engagement portion 52b. As a result, when the insertion portion 52 is inserted into the insertion opening 3a, the restriction portion 62 is engaged with the end portion 62b on the proximal end side of the restriction portion 62 and the step St2 on the proximal end side of the fitting portion 52b. The fitting 6 is restricted from moving to the proximal end side with respect to the insertion portion 52. Then, after the insertion portion 52 is inserted into the insertion opening 3a, when the inner engagement portion 3b of the mating member 3 and the elastic piece 61 are engaged by operating the long member 2, the fitting 6 is engaged in the inner direction. The reaction force from the portion 3b applies a force in the direction of moving the fitting 6 in the distal direction of the insertion portion 52 with respect to the insertion portion 52, but the distal end 62a and the fitting portion 52b of the restriction portion 62 are applied. The front end side step St <b> 1 is engaged, and the fitting 6 is restricted from moving toward the front end side with respect to the insertion portion 52.

ここで、規制部６２における「軸方向の移動を規制する」とは、上述したように、嵌合子６が挿入部５２（嵌合部位５２ｂ）から外れるような軸方向の移動を規制するという意味である。なお、嵌合子６が挿入部５２の嵌合部位５２ｂとの間のわずかなクリアランス間で軸方向に移動するような場合など、規制部６２の長さが嵌合部位５２ｂよりも短く形成されていることにより、嵌合子６が嵌合部位５２ｂにおいて、嵌合部位５２ｂから外れることなく軸方向に移動するような場合は、ここでいう「軸方向の移動」には含まれない。 Here, “restricting movement in the axial direction” in the restricting portion 62 means restricting movement in the axial direction such that the fitting 6 is disengaged from the insertion portion 52 (fitting portion 52b) as described above. It is. The length of the restricting portion 62 is shorter than the fitting portion 52b, such as when the fitting 6 moves in the axial direction with a slight clearance between the fitting portion 52b and the fitting portion 52b. Therefore, the case where the fitting 6 moves in the axial direction in the fitting portion 52b without moving away from the fitting portion 52b is not included in the “movement in the axial direction” here.

規制部６２は、嵌合子６に設けられた複数の弾性片６１の間に設けられている。すなわち、弾性片６１から周方向で離間して、または隣接して、複数の弾性片６１の間に設けられる。本実施形態では、図４（ａ）〜（ｃ）に示されるように、２つの弾性片６１の間に、２つの規制部６２が設けられている。しかしながら、規制部６２の数は特に限定されず、たとえば、４つの弾性片６１が設けられる場合には、４つの弾性片６１の間の４つの空間全てに規制部６２を設ける必要はなく、少なくとも２つの規制部６２が設けられていればよい。規制部６２は、本実施形態では、挿入部５２の嵌合部位５２ｂの軸方向長さとほぼ同じ長さを有し、挿入部５２の形状に沿って軸方向に直線的に設けられているが、嵌合子６の挿入部５２に対する軸方向の移動を規制することができる形状であれば、規制部６２の形状は適宜変更することが可能である。 The restricting portion 62 is provided between the plurality of elastic pieces 61 provided on the fitting 6. That is, the elastic pieces 61 are provided between the elastic pieces 61 so as to be separated from or adjacent to the elastic pieces 61 in the circumferential direction. In the present embodiment, as shown in FIGS. 4A to 4C, two restricting portions 62 are provided between the two elastic pieces 61. However, the number of the restricting portions 62 is not particularly limited. For example, when four elastic pieces 61 are provided, it is not necessary to provide the restricting portions 62 in all four spaces between the four elastic pieces 61. It is only necessary that two restricting portions 62 are provided. In the present embodiment, the restricting portion 62 has substantially the same length as the axial length of the fitting portion 52b of the insertion portion 52, and is linearly provided in the axial direction along the shape of the insertion portion 52. The shape of the restricting portion 62 can be appropriately changed as long as the shape can restrict the axial movement of the fitting 6 with respect to the insertion portion 52.

なお、複数の規制部６２は、連結部６３により連結されているが、この連結部６３の詳細については後述する。 In addition, although the some control part 62 is connected by the connection part 63, the detail of this connection part 63 is mentioned later.

嵌合子６は、図２に示されるように、挿入部５２の先端側（先端部位５２ａ）から嵌め込まれる。このとき、嵌合子６の規制部６２は弾性変形しながら径方向外側に広がり、そのまま嵌合子６を挿入部５２の基端側に向けて嵌め込んでいくと、挿入部５２の先端部位５２ａにより略環状の基部６４が弾性変形して広がる。略環状の基部６４が先端部位５２ａを越えると、嵌合子６は元の形状に復元し、嵌合部位５２ｂに嵌め込まれる。この状態で、環状の基部６４の先端側、規制部６２の先端側の端部６２ａと、連結部６３の基端側と、規制部６２の基端側の端部６２ｂが、両段部Ｓｔ１、Ｓｔ２に挟み込まれて挿入部５２の嵌合部位５２ｂに嵌合し、嵌合子６が端末部材本体５に取り付けられる。 As shown in FIG. 2, the fitting 6 is fitted from the distal end side (the distal end portion 52 a) of the insertion portion 52. At this time, the restricting portion 62 of the fitting 6 spreads radially outward while being elastically deformed. If the fitting 6 is fitted toward the proximal end side of the insertion portion 52 as it is, the distal end portion 52a of the insertion portion 52 The substantially annular base 64 expands due to elastic deformation. When the substantially annular base 64 exceeds the tip portion 52a, the fitting 6 is restored to its original shape and is fitted into the fitting portion 52b. In this state, the distal end side of the annular base portion 64, the distal end portion 62a of the restricting portion 62, the proximal end side of the connecting portion 63, and the proximal end end portion 62b of the restricting portion 62 are both stepped portions St1. The fitting 6 is attached to the terminal member main body 5 by being sandwiched between St2 and fitted into the fitting portion 52b of the insertion portion 52.

従来の構造の場合も、上述した特許文献１に示されるように、略環状の基部と規制部とを有した構造は存在し、同様の取り付け方法で取り付けられていた。この従来の構造で、嵌合子を挿入部に取り付ける場合について、図６ａ〜図６ｆを用いて説明する。 Also in the case of the conventional structure, as shown in Patent Document 1 described above, there is a structure having a substantially annular base portion and a restricting portion, which are attached by the same attachment method. A case where the fitting is attached to the insertion portion with this conventional structure will be described with reference to FIGS. 6a to 6f.

従来の構造では、図６ａに示す状態から、嵌合子６００の規制部６２０の先端部を、挿入部５２０の先端部位５２０ａに押し込んで取り付ける。しかし、嵌合子６００を挿入部５２０に対して強く押し込んだ際に、嵌合子６００と挿入部５２０の軸が合うように、しかも均一に力を加えて押し込まなければ、図６ｂに示されるように、挿入部５２０の軸に対して嵌合子６００の軸が傾いてしまうことがある。この状態のまま嵌合子６００が挿入部５２０に強く押し込まれると、図６ｃに示されるように、少なくとも一方の規制部６２０（図６ｃにおいては図中、下側の規制部６２０）が塑性変形してしまう場合がある。このような場合に、嵌合子６００をそのまま挿入部５２０に差し込んでいくと、図６ｄに示されるように、嵌合子６００は挿入部５２０の嵌合部位５２０ｂに取り付けられるが、塑性変形した規制部６２０は、挿入部５２０の嵌合部位５２０ｂの基端側の段部Ｓｔ２に係合せず、嵌合子６００の挿入部５２０に対する軸方向の移動が規制できなくなる。すなわち、図６ｅに示されるように、規制部６２０の基端側の端部が嵌合部位５２０ｂの基端側の段部Ｓｔ２に係合できない状態で、相手部材３００の挿入開口部３００ａに挿入していくと、挿入開口部３００ａの開口縁と外側に広がった弾性片６１０とが当接する。挿入開口部３００ａの開口縁と弾性片６１０とが当接した後、そのまま挿入していくと、弾性片６１０は、挿入開口部３００ａの開口縁から、図中右側に向かって反力を受けて、嵌合子６００は開口縁から右側に力を受ける。嵌合子６００の規制部６２０のうちの一方は、塑性変形して段部Ｓｔ２と係合しておらず、嵌合子６００の嵌合部位５２０ｂへの嵌合が不安定となっている。したがって、そのまま挿入部５２０を挿入開口部３００ａに挿入していくと、図６ｆに示されるように、不安定な嵌合状態となっている嵌合子６００が嵌合部位５２０ｂの段差Ｓｔ２を越えて嵌合部位５２０ｂの軸方向外側に乗り上げてしまう。このような場合には、端末部材を相手部材にうまく取り付けることができなくなる場合があり、後加工、修正加工して取り付けたり、嵌合子６００を交換して再度取り付け作業をしなければならない場合もある。 In the conventional structure, from the state shown in FIG. 6 a, the distal end portion of the restriction portion 620 of the fitting 600 is pushed into the distal end portion 520 a of the insertion portion 520 and attached. However, as shown in FIG. 6b, when the fitting 600 is strongly pushed into the insertion portion 520, the fitting 600 and the insertion portion 520 are aligned so that the axes of the fitting 600 and the insertion portion 520 are not pushed in evenly. The shaft of the fitting 600 may be inclined with respect to the shaft of the insertion portion 520. When the fitting 600 is strongly pushed into the insertion portion 520 in this state, as shown in FIG. 6c, at least one restricting portion 620 (in FIG. 6c, the lower restricting portion 620 in the drawing) is plastically deformed. May end up. In such a case, when the fitting 600 is inserted into the insertion portion 520 as it is, the fitting 600 is attached to the fitting portion 520b of the insertion portion 520 as shown in FIG. 620 does not engage with the stepped portion St2 on the proximal end side of the fitting portion 520b of the insertion portion 520, and the axial movement of the fitting 600 with respect to the insertion portion 520 cannot be restricted. That is, as shown in FIG. 6e, the proximal end of the restricting portion 620 is inserted into the insertion opening 300a of the mating member 300 in a state where the proximal end of the fitting portion 520b cannot be engaged with the step St2. As a result, the opening edge of the insertion opening 300a comes into contact with the elastic piece 610 spreading outward. When the opening edge of the insertion opening 300a and the elastic piece 610 come into contact with each other and are inserted as they are, the elastic piece 610 receives a reaction force from the opening edge of the insertion opening 300a toward the right side in the figure. The fitting 600 receives a force from the opening edge to the right side. One of the restricting portions 620 of the fitting 600 is plastically deformed and is not engaged with the stepped portion St2, and the fitting of the fitting 600 to the fitting portion 520b is unstable. Therefore, when the insertion portion 520 is inserted into the insertion opening 300a as it is, the fitting 600 in an unstable fitting state exceeds the step St2 of the fitting portion 520b as shown in FIG. 6f. It rides on the outside in the axial direction of the fitting part 520b. In such a case, the terminal member may not be successfully attached to the mating member, and may be post-processed, corrected and attached, or the fitting 600 may need to be replaced and reattached. is there.

一方、本発明の嵌合子６は、図４（ａ）〜（ｃ）に示されるように、複数の規制部６２を、挿入部５２の周方向で互いに連結する連結部６３を有している。すなわち、規制部６２は、図６ａ〜図６ｆに示される従来のものとは異なり、規制部６２同士が周方向で互いに連結されている。規制部６２が塑性変形してしまうのは、規制部６２が挿入部５２に嵌合する際に、外側に広がりすぎてしまうからであるが、規制部６２同士が周方向で互いに連結されている場合は、連結された規制部６２のうち、一方の規制部６２が外側に広がろうとしても、その広がろうとする一方の規制部６２と連結された他方の規制部６２と連結部６３により、一方の規制部６２の広がりが抑制される。したがって、一方の規制部６２が塑性変形してしまうような変形位置まで移動することを防止することができるとともに、挿入部５２に嵌合するときに挿入部５２から受ける力を、それぞれの規制部６２だけで受けるのではなく、連結された他方の規制部６２や、連結部６３により分散させることができる。また、規制部６２が一時的に弾性変形したとしても、連結部６３の弾性復元力も手伝って、規制部６２が元の位置へ戻りやすくなっている。したがって、嵌合子６が挿入部５２に嵌合されるときに、規制部６２が一時的に外周側に広がったとしても、連結部６３が規制部６２同士を連結することにより、規制部６２の端部が確実に端末部材本体５と係合する元の位置まで戻すことができる。それにより、規制部６２の基端側の端部６２ｂが確実に挿入部５２の嵌合部位５２ｂの基端側の段部Ｓｔ２と確実に係合する。したがって、嵌合子６の挿入部５２に対する軸方向の移動を確実に規制することができ、図５（ａ）〜（ｃ）に示したように、嵌合子６が嵌合された挿入部５２を相手部材３の挿入開口部３ａに挿入するときに、弾性片６１が挿入開口部３ａの開口縁から反力を受けても、嵌合子６が挿入部５２に対して軸方向にずれることがない。これにより、端末部材４を相手部材３に対して、確実に接続することができる。また、嵌合子６が挿入部５２に対して軸方向にずれることがないので、嵌合子６と端末部材本体５との間でのガタが抑制され、ガタに起因する異音も抑制することができる。 On the other hand, as shown in FIGS. 4A to 4C, the fitting 6 of the present invention has a connecting portion 63 that connects a plurality of restricting portions 62 to each other in the circumferential direction of the inserting portion 52. . That is, the restricting portion 62 is connected to each other in the circumferential direction, unlike the conventional one shown in FIGS. 6a to 6f. The reason why the restricting portion 62 is plastically deformed is that when the restricting portion 62 is fitted to the insertion portion 52, the restricting portion 62 is excessively spread outward, but the restricting portions 62 are connected to each other in the circumferential direction. In this case, even if one of the restricting portions 62 is connected to the outside, the other restricting portion 62 and the connecting portion 63 connected to the one restricting portion 62 that is going to spread. , The spread of one restricting portion 62 is suppressed. Accordingly, it is possible to prevent one of the restricting portions 62 from moving to a deformation position where the restricting portion 62 is plastically deformed, and the force received from the insertion portion 52 when fitted to the insertion portion 52 is reduced to each restricting portion. Instead of being received only by 62, it can be dispersed by the other restricting portion 62 connected or the connecting portion 63. Further, even if the restricting portion 62 is temporarily elastically deformed, the restricting portion 62 is easily returned to the original position with the help of the elastic restoring force of the connecting portion 63. Therefore, when the fitting 6 is fitted into the insertion portion 52, the connecting portion 63 connects the restricting portions 62 to each other even if the restricting portion 62 temporarily spreads to the outer peripheral side. The end portion can be reliably returned to the original position where it engages with the terminal member main body 5. Thereby, the end 62b on the proximal end side of the restricting portion 62 is reliably engaged with the stepped portion St2 on the proximal end side of the fitting portion 52b of the insertion portion 52. Therefore, the axial movement of the fitting 6 with respect to the insertion portion 52 can be surely restricted, and the insertion portion 52 with the fitting 6 fitted therein can be moved as shown in FIGS. Even when the elastic piece 61 receives a reaction force from the opening edge of the insertion opening 3 a when inserted into the insertion opening 3 a of the mating member 3, the fitting 6 does not shift in the axial direction with respect to the insertion part 52. . Thereby, the terminal member 4 can be reliably connected to the counterpart member 3. Moreover, since the fitting 6 does not shift in the axial direction with respect to the insertion portion 52, backlash between the fitting 6 and the terminal member main body 5 is suppressed, and abnormal noise caused by backlash is also suppressed. it can.

連結部６３は、上述したように、複数の規制部６２を連結して、規制部６２の塑性変形を防止する部位である。したがって、連結部６３は、複数の規制部６２を連結して、規制部６２の塑性変形を防止することができるものであれば、その形状や位置、個数は特に限定されない。たとえば、本実施形態では、図４（ａ）〜（ｃ）に示されるように、嵌合子６に２つの規制部６２が設けられ、その２つの規制部６２を連結部６３により連結しているが、たとえば、嵌合子６に４つの規制部が設けられている場合、４つのうち２つの規制部を１つの連結部により連結し、さらに２つの規制部をもう１つの連結部により連結してもよいし、４つ全ての規制部を１つの連結部により連結しても構わない。また、本実施形態では、図４（ａ）〜（ｃ）に示されるように、連結部６３は、複数の規制部６２のうち、挿入部５２の基端側の端部６２ｂ同士を連結している。この場合、挿入部５２の基端側となる、規制部６２の端部６２ｂ同士を連結することにより、規制部６２の塑性変形を規制部６２の軸方向全体にわたって抑えることができる。しかしながら、連結部６３を設ける位置は、規制部６２の端部６２ｂに限定されず、規制部６２の長手方向の中央や、中央から端部６２ｂまでの間など、規制部６２の塑性変形を防止することができる位置に設けられていればよい。 As described above, the connecting portion 63 is a portion that connects the plurality of restricting portions 62 to prevent plastic deformation of the restricting portions 62. Therefore, the shape, position, and number of the connecting portion 63 are not particularly limited as long as the connecting portion 63 can connect the plurality of restricting portions 62 to prevent plastic deformation of the restricting portions 62. For example, in this embodiment, as shown in FIGS. 4A to 4C, the fitting 6 is provided with two restricting portions 62, and the two restricting portions 62 are connected by a connecting portion 63. However, for example, when the four restricting portions are provided in the fitting 6, two of the four restricting portions are connected by one connecting portion, and further two restricting portions are connected by another connecting portion. Alternatively, all four restricting portions may be connected by one connecting portion. In this embodiment, as shown in FIGS. 4A to 4C, the connecting portion 63 connects the end portions 62 b on the proximal end side of the insertion portion 52 among the plurality of restricting portions 62. ing. In this case, the plastic deformation of the restricting portion 62 can be suppressed over the entire axial direction of the restricting portion 62 by connecting the end portions 62b of the restricting portion 62, which are on the proximal end side of the insertion portion 52. However, the position where the connecting portion 63 is provided is not limited to the end portion 62b of the restricting portion 62, and prevents plastic deformation of the restricting portion 62 such as the center in the longitudinal direction of the restricting portion 62 or between the center and the end portion 62b. It suffices if it is provided at a position where it can be performed.

また、連結部６３は、挿入部５２の周方向で規制部６２同士を連結しているが、ここでいう挿入部５２の周方向とは、嵌合子６が挿入部５２に取り付けられた際の、挿入部５２の軸周りのことをいい、挿入部５２の軸周りで規制部６２同士が連結され、規制部６２の塑性変形を防止することができるように連結部６３が設けられていればよい。したがって、連結部６３が挿入部５２の外周に沿って挿入部５２の外周に接触するように設けられているものに限られず、挿入部５２の外周から離間するように連結部６３が設けられていても構わない。なお、本実施形態では、挿入部５２が略円柱状に形成され、連結部６３が、円柱状の挿入部５２の周方向に沿うように、円弧状に形成されている。連結部６３が、円弧状に形成されている場合、嵌合子６を挿入部５２に嵌合したときに、嵌合子６が略円柱状の挿入部５２の外周に確実に嵌合し、嵌合子６の挿入部５２への取り付けがより確実になる。また、連結部６３が円弧状に形成されていることにより、挿入部５２への嵌合時に、円弧状の連結部６３が、円弧の径が大きくなるように弾性変形しながら嵌合するため、連結部６３と連結されている規制部６２の塑性変形をより防止することができる。しかしながら、連結部６３の形状は円弧状に限定されるものではなく、挿入部５２の形状に応じて適宜変更が可能であるし、挿入部５２の形状とは異なる形状としても構わない。 The connecting portion 63 connects the restricting portions 62 to each other in the circumferential direction of the insertion portion 52. The circumferential direction of the insertion portion 52 referred to here means that the fitting 6 is attached to the insertion portion 52. If the connecting portion 63 is provided so that the restricting portions 62 are connected around the axis of the inserting portion 52 and plastic deformation of the restricting portion 62 can be prevented. Good. Accordingly, the connecting portion 63 is not limited to be provided so as to be in contact with the outer periphery of the insertion portion 52 along the outer periphery of the insertion portion 52, and the connecting portion 63 is provided so as to be separated from the outer periphery of the insertion portion 52. It doesn't matter. In the present embodiment, the insertion portion 52 is formed in a substantially cylindrical shape, and the connecting portion 63 is formed in an arc shape so as to follow the circumferential direction of the cylindrical insertion portion 52. When the connecting portion 63 is formed in an arc shape, when the fitting 6 is fitted to the insertion portion 52, the fitting 6 reliably fits to the outer periphery of the substantially cylindrical insertion portion 52, and the fitting 6 to the insertion part 52 becomes more reliable. In addition, since the connecting portion 63 is formed in an arc shape, the arc-shaped connecting portion 63 is fitted while being elastically deformed so that the diameter of the arc increases when fitting to the insertion portion 52. Plastic deformation of the restricting portion 62 connected to the connecting portion 63 can be further prevented. However, the shape of the connecting portion 63 is not limited to an arc shape, and can be changed as appropriate according to the shape of the insertion portion 52, or may be different from the shape of the insertion portion 52.

また、本実施形態では、図４（ａ）〜（ｃ）に示されるように、規制部６２が略円柱状の挿入部５２の外周に沿ってほぼ等間隔で２つ設けられ、連結部６３は、規制部６２の基端側同士を連結し、連結部６３は、挿入部５２の外周に沿ってアーチ状（半円状）に設けられている。アーチ状に設けられた連結部６３は、挿入部５２の周方向のうち約半分を覆い、周方向のうち約半分は開放している。また、弾性片６１の軸方向の長さは、規制部６２の長さよりも短くなっている。この場合、嵌合子６を挿入部５２に嵌合する場合、規制部６２の基端側の端部６２ｂ側から挿入部５２の先端部位５２ａに嵌め込んでもよいし、規制部６２の基端側の端部６２ｂ側から嵌め込まずに、図４（ａ）および（ｃ）に示す規制部６２の側部６２ｃ側から挿入部５２の軸方向に垂直な方向に挿入部５２を押し込むことにより嵌合することもできる。したがって、図４（ａ）〜（ｃ）に示した実施形態の構成によれば、端末部材本体５と嵌合子６との組み付けの自由度が高まり、かつ規制部６２の塑性変形を防止することができる。 In the present embodiment, as shown in FIGS. 4A to 4C, two restricting portions 62 are provided at substantially equal intervals along the outer periphery of the substantially cylindrical insertion portion 52, and the connecting portion 63. Connects the base end sides of the restricting portion 62, and the connecting portion 63 is provided in an arch shape (semicircular shape) along the outer periphery of the insertion portion 52. The connecting portion 63 provided in an arch shape covers approximately half of the circumferential direction of the insertion portion 52, and approximately half of the circumferential direction is open. Further, the length of the elastic piece 61 in the axial direction is shorter than the length of the restricting portion 62. In this case, when fitting the fitting 6 into the insertion portion 52, the fitting 6 may be fitted into the distal end portion 52 a of the insertion portion 52 from the proximal end side 62 b of the restriction portion 62, or the proximal end side of the restriction portion 62. The fitting portion 52 is fitted by pushing the insertion portion 52 in the direction perpendicular to the axial direction of the insertion portion 52 from the side portion 62c side of the restriction portion 62 shown in FIGS. 4A and 4C without being fitted from the end portion 62b side. You can also Therefore, according to the configuration of the embodiment shown in FIGS. 4A to 4C, the degree of freedom in assembling the terminal member main body 5 and the fitting 6 is increased, and plastic deformation of the restricting portion 62 is prevented. Can do.

図７（ａ）および（ｂ）は、上述の実施形態の変形例である。上述の実施形態では、嵌合部位５２ｂの基端側の段部Ｓｔ２が、取付部５１と挿入部５２の境界部からわずかに先端側に位置していたが、図７（ａ）および（ｂ）に示す変形例では、嵌合部位５２ｂの基端側の段部Ｓｔ２が取付部５１と挿入部５２の境界部に位置している。図７（ａ）および（ｂ）に示す変形例では、端末部材本体５の取付部５１が、挿入部５２よりも大きい柱状に形成され、取付部５１に、コントロールケーブルのインナーケーブル２２ａ、２２ｂのケーブルエンド（端末２１ａ、２１ｂ）が係止される係止凹部５１ａが形成されている。係止凹部５１ａは、取付部５１のうち、挿入部５２が延びる側の端面５１ｂにおいて開口し、連結部６３が取付部５１の端面５１ｂに係合するとともに、連結部６３が取付部５１の端面５１ｂにおける係止凹部５１ａの開口幅Ｗよりも長く形成されている。連結部６３が取付部５１の端面５１ｂに係合し、連結部６３が係止凹部５１ａの開口幅Ｗよりも長く形成されていることにより、挿入部５２を相手部材３の挿入開口部３ａに挿入する際に、規制部６２が取付部５１の端面５１ｂで係止凹部５１ａに嵌まり込まず、嵌合子６が挿入部５２に対して軸方向にずれることがなく、確実に係止される。すなわち、係止凹部５１ａの開口幅Ｗよりも幅広の連結部６３が設けられていることにより、係止凹部５１ａが端面５１ｂで開口している場合であっても、規制部６２が係止凹部５１ａの端面５１ｂの開口に嵌まり込んで、嵌合子６が軸方向にずれてしまうことがなくなる。よって、係止凹部５１ａを、取付部５１の端面５１ｂにおいて開口させることにより、取付部５１の軸方向の長さを短くすることができ、さらに、嵌合子６の挿入部５２に対する軸方向でのずれを確実に防止することができる。 FIGS. 7A and 7B are modifications of the above-described embodiment. In the above-described embodiment, the stepped portion St2 on the proximal end side of the fitting portion 52b is located slightly on the distal end side from the boundary portion between the attachment portion 51 and the insertion portion 52. However, FIGS. In the modification shown in FIG. 5, the stepped portion St <b> 2 on the proximal end side of the fitting portion 52 b is located at the boundary portion between the attachment portion 51 and the insertion portion 52. In the modification shown in FIGS. 7A and 7B, the attachment portion 51 of the terminal member body 5 is formed in a columnar shape larger than the insertion portion 52, and the inner cables 22a and 22b of the control cable are formed on the attachment portion 51. A locking recess 51a for locking the cable end (terminals 21a, 21b) is formed. The locking recess 51 a opens in the end surface 51 b on the side of the mounting portion 51 where the insertion portion 52 extends, the connecting portion 63 engages with the end surface 51 b of the mounting portion 51, and the connecting portion 63 is the end surface of the mounting portion 51. It is formed longer than the opening width W of the locking recess 51a in 51b. Since the connecting portion 63 engages with the end surface 51b of the mounting portion 51 and the connecting portion 63 is formed longer than the opening width W of the locking recess 51a, the insertion portion 52 becomes the insertion opening 3a of the mating member 3. When inserting, the restricting portion 62 does not fit into the locking recess 51 a at the end surface 51 b of the mounting portion 51, and the fitting 6 is securely locked without being displaced in the axial direction with respect to the inserting portion 52. . That is, by providing the connecting portion 63 wider than the opening width W of the locking recess 51a, even if the locking recess 51a is opened at the end surface 51b, the restricting portion 62 is locked to the locking recess. The fitting 6 is not displaced in the axial direction by fitting into the opening of the end surface 51b of the 51a. Therefore, by opening the locking recess 51a at the end surface 51b of the mounting portion 51, the axial length of the mounting portion 51 can be shortened, and further, the axial direction of the fitting 6 with respect to the insertion portion 52 can be reduced. Deviation can be reliably prevented.
