Description

本発明は、コネクタに関する。 The present invention relates to connectors.

雌端子を収容する雌ハウジングと、雄端子を収容する雄ハウジングとが嵌合されることで、雌端子と雄端子とが電気的に接続される嵌合コネクタが知られている。このような嵌合コネクタでは、車両の走行時等の振動により外力が加わると、雌端子と雄端子との間で微摺動摩耗を生じる虞がある。このような微摺動摩耗により生じた摩耗粉が雌端子と雄端子との間に介在すると、雌端子と雄端子との電気接続信頼性が低下する可能性がある。 2. Description of the Related Art There is known a mating connector in which a female terminal and a male terminal are electrically connected by fitting a female housing that accommodates a female terminal and a male housing that accommodates a male terminal. In such a fitting connector, when an external force is applied due to vibration during running of a vehicle, there is a possibility that fine sliding wear may occur between the female terminal and the male terminal. If abrasion powder generated by such fine sliding wear is interposed between the female terminal and the male terminal, there is a possibility that the reliability of the electrical connection between the female terminal and the male terminal will be lowered.

そこで、タブ(雄端子)の移動に起因する摩耗を抑制する端子金具を提供する技術が知られている(例えば、特許文献1)。
特許文献1に記載された端子金具は、相手側端子のタブが挿入される角筒部内に設けられた弾性接触片と受け部との間で、タブを厚さ方向に挟むように構成されている。更に、角筒部の側壁に形成された弾性片がタブの側縁を幅方向に押圧することで、タブの幅方向への変位が抑制されるように構成されている。
そこで、角筒部内に挿入された相手側端子のタブは、タブの幅方向への移動に起因するタブ、弾性接触片、受け部の摩耗を抑制することができる。
Therefore, there is known a technique for providing a terminal fitting that suppresses wear due to movement of a tab (male terminal) (for example, Patent Document 1).
The terminal metal fitting described in Patent Document 1 is configured such that the tab of the mating terminal is sandwiched in the thickness direction between an elastic contact piece and a receiving portion provided in a square tubular portion into which the tab of the mating terminal is inserted. there is Furthermore, the elastic piece formed on the side wall of the square tube presses the side edge of the tab in the width direction, thereby suppressing the displacement of the tab in the width direction.
Therefore, the tab of the mating terminal inserted into the rectangular tubular portion can suppress abrasion of the tab, the elastic contact piece, and the receiving portion due to the movement of the tab in the width direction.

しかしながら、上記特許文献1に記載された端子金具は、相手側端子のタブを角筒部内に挿入する際には、タブにより弾性接触片と弾性片とを同時に弾性変形させる必要があり、端子金具に相手側端子のタブを挿入する挿入力が高くなってしまう。そのため、端子金具と相手側端子を嵌合するコネクタ嵌合力が高くなり、作業性が低下するという問題がある。 However, in the terminal fitting described in Patent Document 1, when inserting the tab of the mating terminal into the rectangular tubular portion, it is necessary to elastically deform the elastic contact piece and the elastic piece at the same time by the tab. The insertion force for inserting the tab of the mating terminal into the Therefore, there is a problem that the connector fitting force for fitting the terminal fitting and the mating terminal is increased, and the workability is deteriorated.

図7は、図6に示したコネクタ10のコネクタアッセンブリ10Aと相手側コネクタ50とが嵌合された嵌合コネクタアッセンブリ1Aに、電線接続部材30が挿入される前の状態を示す縦断面図である。図8は、図7に示した電線接続部材30の挿入片37が嵌合コネクタアッセンブリ1Aの端子接続部材20に挿入される状態を示す要部拡大断面図、図9は図8に示した電線接続部材30の挿入片37が端子接続部材20の端子バネ25により抜け止め係止された状態を示す要部拡大断面図である。 FIG. 7 is a longitudinal sectional view showing a state before the wire connection member 30 is inserted into the mating connector assembly 1A in which the connector assembly 10A of the connector 10 shown in FIG. 6 and the mating connector 50 are mated. be. 8 is an enlarged cross-sectional view of a main part showing a state in which the insertion piece 37 of the wire connection member 30 shown in FIG. 7 is inserted into the terminal connection member 20 of the mating connector assembly 1A, and FIG. 4 is an enlarged cross-sectional view of a main part showing a state in which an insertion piece 37 of a connection member 30 is retained by a terminal spring 25 of a terminal connection member 20 to prevent it from slipping off; FIG.

コネクタアッセンブリ10Aと相手側コネクタ50との嵌合過程では、ハウジング12の端子挿入口13から端子収容室18に挿入された相手側端子70のタブ77が、端子本体部22内に挿入され、端子バネ25を弾性変形させる。 In the process of fitting the connector assembly 10A and the mating connector 50, the tabs 77 of the mating terminals 70 inserted into the terminal receiving chambers 18 from the terminal insertion openings 13 of the housing 12 are inserted into the terminal body portions 22, and the terminals are fitted together. The spring 25 is elastically deformed.

図7に示したように、コネクタアッセンブリ10Aと相手側コネクタ50との嵌合が完了すると、端子バネ25の弾性変形による復元力により、相手側端子70のタブ77と端子接続部材20の端子バネ25が接触する。そこで、相手側端子70は、タブ77が端子接続部材20における端子バネ25と接触凸部27とに挟持される状態で、端子接続部材20に電気的に接続される。 As shown in FIG. 7, when the mating of the connector assembly 10A and the mating connector 50 is completed, the elastic deformation of the terminal spring 25 causes the tab 77 of the mating terminal 70 and the terminal spring of the terminal connection member 20 to move. 25 come into contact. Therefore, the mating terminal 70 is electrically connected to the terminal connecting member 20 while the tab 77 is sandwiched between the terminal spring 25 and the contact protrusion 27 of the terminal connecting member 20 .

コネクタアッセンブリ10Aと相手側コネクタ50とが嵌合されると、相手側ハウジング52の被ロック突起(図示せず)がハウジング12のロックアーム16に係止され、相手側ハウジング52とハウジング12との嵌合状態が維持される。 When the connector assembly 10A and the mating connector 50 are mated, the locking projection (not shown) of the mating housing 52 is engaged with the lock arm 16 of the housing 12, and the mating housing 52 and the housing 12 are locked. The mated state is maintained.

次に、図7に示すように、電線60の端末に接続された電線接続部材30が、ハウジング12の端子収容室18に挿入され、コネクタアッセンブリ10Aと相手側コネクタ50とが嵌合された嵌合コネクタアッセンブリ1Aの端子接続部材20に組み付けられる。 Next, as shown in FIG. 7, the wire connection member 30 connected to the end of the wire 60 is inserted into the terminal receiving chamber 18 of the housing 12, and the connector assembly 10A and the mating connector 50 are fitted together. It is attached to the terminal connection member 20 of the mating connector assembly 1A.

端子接続部材20と電線接続部材30との結合過程では、図8に示すように、後方開口24から端子本体部22内に挿入された挿入片37の押圧突起39が、端子バネ25の先端に形成された湾曲部28に当接する。 In the process of connecting the terminal connection member 20 and the wire connection member 30, as shown in FIG. It abuts on the formed curved portion 28 .

そして、電線接続部材30の挿入片37が端子本体部22内にさらに挿入されることで、押圧突起39は端子バネ25の湾曲部28を押し上げながら通過する。そして、図9に示すように、端子接続部材20と電線接続部材30との結合が完了すると、押圧突起39は端子バネ25の傾斜部26に達する。このように、端子接続部材20と電線接続部材30とは、互いの結合が完了することで、一体的に連結されると共に電気的に接続されて端子40になる。 By further inserting the insertion piece 37 of the wire connection member 30 into the terminal main body 22 , the pressing protrusion 39 pushes up the curved portion 28 of the terminal spring 25 and passes through. Then, as shown in FIG. 9 , when the connection between the terminal connection member 20 and the wire connection member 30 is completed, the pressing projection 39 reaches the inclined portion 26 of the terminal spring 25 . In this manner, the terminal connection member 20 and the wire connection member 30 are integrally connected and electrically connected to form the terminal 40 by completing the mutual coupling.

尚、電線接続部30の挿入片37が端子本体部22内に挿入された状態において、電線接続部30と端子本体部22との間には、係合機構が設けられている方が望ましい。係合機構としては、例えば図9中に示したように、端子本体部22の底壁22aに係合突起Xが設けられ(図4、参照)、導体圧着部31の底壁に係合孔Yが設けられる(図2、参照)。係合突起Xと係合孔Yとの係合により、電線接続部30と端子本体部22とが、より一体的に連結された状態を維持できる。 It is desirable that an engagement mechanism be provided between the wire connection portion 30 and the terminal body portion 22 when the insertion piece 37 of the wire connection portion 30 is inserted into the terminal body portion 22 . As an engaging mechanism, for example, as shown in FIG. Y is provided (see FIG. 2). Due to the engagement between the engaging protrusion X and the engaging hole Y, the wire connection portion 30 and the terminal main body portion 22 can be maintained in a more integrally connected state.

端子接続部材20と電線接続部材30との結合が完了して端子バネ25の傾斜部26に係合した挿入片37の押圧突起39は、端子バネ25の傾斜部26を押圧する。そして、端子バネ25の弾性変形による復元力と、端子バネ25の傾斜部26を押圧する押圧突起39の押圧力とにより、相手側端子70のタブ77と端子接続部材20の端子バネ25とが接触する。
そこで、相手側端子70は、タブ77が端子接続部材20における端子バネ25と接触凸部27とに挟持される状態で、端子40に電気的に接続される。
After the connection between the terminal connection member 20 and the wire connection member 30 is completed, the pressing protrusion 39 of the insertion piece 37 engaged with the inclined portion 26 of the terminal spring 25 presses the inclined portion 26 of the terminal spring 25 . Then, the tab 77 of the mating terminal 70 and the terminal spring 25 of the terminal connecting member 20 are pulled together by the restoring force due to the elastic deformation of the terminal spring 25 and the pressing force of the pressing projection 39 pressing the inclined portion 26 of the terminal spring 25 . Contact.
Therefore, the mating terminal 70 is electrically connected to the terminal 40 while the tab 77 is sandwiched between the terminal spring 25 and the contact protrusion 27 of the terminal connecting member 20 .

図10は、本第1実施形態に係るコネクタ10と相手側コネクタ50とが電気的に接続された状態を示す嵌合コネクタ1の縦断面図である。
図10に示すように、嵌合コネクタアッセンブリ1Aは、3つの電線接続部材30が端子接続部材20にそれぞれ組み付けられることで、嵌合コネクタ1が組み立てられたことになる。
FIG. 10 is a longitudinal sectional view of the mating connector 1 showing a state in which the connector 10 and the mating connector 50 are electrically connected according to the first embodiment.
As shown in FIG. 10, the fitting connector assembly 1A is assembled by assembling the three wire connection members 30 to the terminal connection members 20, respectively.

なお、嵌合コネクタ1は、被ロック突起(図示せず)とロックアーム16のロックにより、相手側コネクタ50とコネクタ10との嵌合状態が維持されている。嵌合コネクタ1の離脱は、ロックアーム16を操作して被ロック突起とロックアーム16のロックを解除し、相手側コネクタ50の嵌合空間58からコネクタ10を引き抜くことにより行われる。 In the mating connector 1 , the mating state of the mating connector 50 and the connector 10 is maintained by locking the locking projection (not shown) and the lock arm 16 . Disengagement of the mating connector 1 is performed by operating the lock arm 16 to unlock the locked projection and the lock arm 16 and pulling out the connector 10 from the mating space 58 of the mating connector 50 .

次に、本第1実施形態に係るコネクタ10の作用効果を説明する。
上述したように、本第1実施形態に係るコネクタ10によれば、ハウジング12の端子収容室18に収容される端子40は、図2に示したように、端子接続部材20と電線接続部材30の2部品で構成されている。
Next, functions and effects of the connector 10 according to the first embodiment will be described.
As described above, according to the connector 10 according to the first embodiment, the terminals 40 accommodated in the terminal accommodating chambers 18 of the housing 12 are composed of the terminal connection member 20 and the wire connection member 30 as shown in FIG. consists of two parts.

そこで、先ずは3つの端子接続部材20をハウジング12の端子収容室18にそれぞれ挿入して可撓係止片15に抜け止め係止させることにより、コネクタ10のコネクタアッセンブリ10Aが組み立てられる。 First, the connector assembly 10A of the connector 10 is assembled by inserting the three terminal connecting members 20 into the terminal receiving chambers 18 of the housing 12 and locking them with the flexible locking pieces 15 to prevent them from coming off.

次に、図6に示したように、コネクタアッセンブリ10Aが、相手側コネクタ50に嵌合される。この際、相手側端子70のタブ77が、端子接続部材20の端子本体部22内に挿入されて端子バネ25を弾性変形させる。そこで、端子バネ25の弾性変形による復元力により、相手側端子70のタブ77と端子接続部材20の端子バネ25が接触する。 Next, the connector assembly 10A is mated with the mating connector 50 as shown in FIG. At this time, the tab 77 of the mating terminal 70 is inserted into the terminal body portion 22 of the terminal connecting member 20 to elastically deform the terminal spring 25 . Therefore, the tab 77 of the mating terminal 70 and the terminal spring 25 of the terminal connecting member 20 come into contact with each other due to the restoring force due to the elastic deformation of the terminal spring 25 .

即ち、端子接続部材20の端子本体部22内に挿入される相手側端子70のタブ77に対しては、端子バネ25の弾性変形による復元力だけが作用し、端子接続部材20の端子本体部22内に相手側端子70のタブ77を挿入する挿入力が高くなるのを抑えることができる。そのため、コネクタ10と相手側コネクタ50とを嵌合するコネクタ嵌合力も、高くなるのを抑えることができる。 That is, only the restoring force due to the elastic deformation of the terminal spring 25 acts on the tab 77 of the mating terminal 70 inserted into the terminal body portion 22 of the terminal connection member 20 , and the terminal body portion of the terminal connection member 20 is retained. It is possible to suppress an increase in the insertion force for inserting the tab 77 of the mating terminal 70 into the 22 . Therefore, it is possible to prevent the connector fitting force for fitting the connector 10 and the mating connector 50 from increasing.

そして、図7に示したように、電線60の端末に接続された電線接続部材30が、コネクタアッセンブリ10Aと相手側コネクタ50とが嵌合された嵌合コネクタアッセンブリ1Aの端子接続部材20に組み付けられる。この際、電線接続部材30の挿入片37が端子接続部材20の端子本体部22内に挿入され、端子バネ25の傾斜部26に係合した挿入片37の押圧突起39は、端子バネ25の傾斜部26を押圧する。 Then, as shown in FIG. 7, the wire connection member 30 connected to the end of the wire 60 is assembled to the terminal connection member 20 of the fitting connector assembly 1A to which the connector assembly 10A and the mating connector 50 are fitted. be done. At this time, the insertion piece 37 of the wire connection member 30 is inserted into the terminal body portion 22 of the terminal connection member 20 , and the pressing protrusion 39 of the insertion piece 37 engaged with the inclined portion 26 of the terminal spring 25 is pushed into the terminal spring 25 . The inclined portion 26 is pressed.

即ち、端子接続部材20における端子バネ25と接触凸部27とに挟持される相手側端子70のタブ77に対しては、端子バネ25の弾性変形による復元力と、端子バネ25の傾斜部26を押圧する押圧突起39の押圧力とが作用し、相手側端子70のタブ77と端子接続部材20の端子バネ25とは強く接触することができる。 That is, the tab 77 of the mating terminal 70 sandwiched between the terminal spring 25 and the contact protrusion 27 of the terminal connection member 20 is subjected to the restoring force due to the elastic deformation of the terminal spring 25 and the inclined portion 26 of the terminal spring 25 . The tab 77 of the mating terminal 70 and the terminal spring 25 of the terminal connecting member 20 can strongly contact each other.

そこで、3つの電線接続部材30が嵌合コネクタアッセンブリ1Aの端子接続部材20にそれぞれ接続されて組み立てられた嵌合コネクタ1は、端子40と相手側端子70とのガタ付きによる端子バネ25とタブ77との間での微摺動摩耗が抑制される。この微摺動摩耗の抑制により、微摺動摩耗により生じる摩耗粉が端子バネ25とタブ77との間に介在してしまうことが防止される。このため、端子40と相手側端子70の電気接続信頼性が低下することを抑制できる。
従って、本第1実施形態に係るコネクタ10によれば、コネクタ嵌合力が高くなるのを抑えつつ、端子40の微摺動摩耗を抑制することができる。
Therefore, the mating connector 1 assembled by connecting the three wire connecting members 30 to the terminal connecting members 20 of the mating connector assembly 1A has the terminal springs 25 and the tabs caused by looseness between the terminals 40 and the mating terminals 70. 77 is suppressed. Suppression of this micro-sliding wear prevents abrasion dust generated by the micro-sliding wear from intervening between the terminal spring 25 and the tab 77 . Therefore, it is possible to suppress the deterioration of the electrical connection reliability between the terminal 40 and the mating terminal 70 .
Therefore, according to the connector 10 according to the first embodiment, it is possible to suppress fine sliding wear of the terminals 40 while suppressing an increase in the connector fitting force.

図11は本発明の第2実施形態に係るコネクタ110のコネクタアッセンブリ110Aに、電線接続部材30が挿入される状態を示す縦断面図、図12は図11に示したコネクタ110と相手側コネクタ50との嵌合途中状態を示す縦断面図である。なお、本第2実施形態に係るコネクタ110は、端子40に代えて端子40Aが用いられた以外は上記第1実施形態のコネクタ10と同様の構成であるので、同様の構成部材には同符号を付して詳細な説明を省略する。 11 is a longitudinal sectional view showing a state in which the wire connection member 30 is inserted into the connector assembly 110A of the connector 110 according to the second embodiment of the present invention, and FIG. 12 shows the connector 110 and the mating connector 50 shown in FIG. It is a vertical cross-sectional view showing a state in the middle of fitting with. Note that the connector 110 according to the second embodiment has the same configuration as the connector 10 of the first embodiment except that the terminal 40A is used instead of the terminal 40, so the same reference numerals are used for the same constituent members. and detailed description is omitted.

本第2実施形態に係るコネクタ110の端子40Aは、図11に示すように、端子接続部材20Aと電線接続部材30の2部品で構成されている。
端子接続部材20Aは、端子本体部22内に設けられた端子バネ25と、抜け止め片21とを有する。そして、端子接続部材20Aがハウジング12の端子収容室18に収容されることで、コネクタ110のコネクタアッセンブリ110Aが構成される。
The terminal 40A of the connector 110 according to the second embodiment is composed of two parts, a terminal connection member 20A and a wire connection member 30, as shown in FIG.
The terminal connection member 20</b>A has a terminal spring 25 provided inside the terminal main body 22 and a retaining piece 21 . A connector assembly 110A of the connector 110 is constructed by accommodating the terminal connecting member 20A in the terminal accommodating chamber 18 of the housing 12. As shown in FIG.

抜け止め片21は、端子バネ25に対向する上壁22bに切り起こし形成されて先端が内方へ突出する矩形状の突出片である。抜け止め片21は、端子接続部材20Aの端子本体部22内に電線接続部材30の挿入片37が挿入された際、挿入片37の押圧突起39を端子バネ25の湾曲部28より後方位置で抜け止め係止する。 The retainer piece 21 is a rectangular protruding piece formed by cutting and raising an upper wall 22b facing the terminal spring 25 and protruding inward at its tip. When the insertion piece 37 of the wire connection member 30 is inserted into the terminal main body portion 22 of the terminal connection member 20A, the retaining piece 21 pushes the pressing projection 39 of the insertion piece 37 at a position behind the curved portion 28 of the terminal spring 25. Lock it to prevent it from coming off.

そこで、図12に示すように、コネクタアッセンブリ110Aの端子収容室18に挿入されて端子接続部材20Aの抜け止め片21によって挿入片37の押圧突起39が抜け止め係止された電線接続部材30は、端子接続部材20Aに対して挿入方向に相対的なスライドが可能な仮組み付け状態で端子40Aを構成することができる。 Therefore, as shown in FIG. 12, the wire connecting member 30 is inserted into the terminal accommodating chamber 18 of the connector assembly 110A and the pressing protrusion 39 of the insertion piece 37 is retained by the retaining piece 21 of the terminal connecting member 20A. , the terminal 40A can be configured in a temporarily assembled state in which it is possible to slide relative to the terminal connection member 20A in the insertion direction.

即ち、電線接続部材30がコネクタアッセンブリ110Aの端子収容室18に挿入されて、仮組み付け状態として端子接続部材20Aに組み付けられることで、コネクタアッセンブリ110Aは端子40Aを端子収容室18に収容したコネクタ110となる。 That is, the wire connecting member 30 is inserted into the terminal accommodating chamber 18 of the connector assembly 110A and attached to the terminal connecting member 20A in a temporary assembly state. becomes.

次に、図12~図14を参照しながら上記コネクタ110と相手側コネクタ50とを嵌合する嵌合コネクタ101の組立手順を説明する。
図13は図12に示した電線接続部材30の挿入片37が端子接続部材20Aの抜け止め片21により抜け止め係止された状態を示す要部拡大断面図、図14は図13に示した電線接続部材30の挿入片37が端子接続部材20Aの端子バネ25により抜け止め係止された状態を示す要部拡大断面図である。
Next, the procedure for assembling the fitting connector 101 for fitting the connector 110 and the mating connector 50 will be described with reference to FIGS. 12 to 14. FIG.
13 is an enlarged cross-sectional view of a main part showing a state in which the insertion piece 37 of the wire connection member 30 shown in FIG. 12 is retained by the retaining piece 21 of the terminal connection member 20A, and FIG. 4 is an enlarged cross-sectional view of a main part showing a state in which an insertion piece 37 of a wire connection member 30 is retained by a terminal spring 25 of a terminal connection member 20A to prevent it from slipping out; FIG.

先ず、図11に示したように、電線60の端末に接続された電線接続部材30が、コネクタアッセンブリ110Aの端子収容室18にそれぞれ挿入される。そして、挿入片37の押圧突起39が端子接続部材20Aの抜け止め片21を押し上げながら通過し、押圧突起39は端子バネ25の湾曲部28と抜け止め片21との間まで挿入される。 First, as shown in FIG. 11, the wire connecting members 30 connected to the ends of the wires 60 are inserted into the terminal accommodating chambers 18 of the connector assembly 110A. Then, the pressing protrusion 39 of the insertion piece 37 pushes up and passes through the retaining piece 21 of the terminal connection member 20A, and the pressing protrusion 39 is inserted between the curved portion 28 of the terminal spring 25 and the retaining piece 21 .

すると、端子接続部材20Aの抜け止め片21に挿入片37の押圧突起39が抜け止め係止された電線接続部材30は、端子接続部材20Aに対して挿入方向に相対的なスライドが可能な仮組み付け状態となった端子40Aを構成する。即ち、コネクタアッセンブリ110Aの端子収容室18に収容された端子40Aは、電線接続部材30が端子接続部材20Aに対して仮組み付け状態とされたコネクタ110を構成する。この電線接続部材30が端子接続部材20Aに対して仮組み付け状態とされたコネクタ110は、運搬などにより取り扱う際、電線接続部材30と端子接続部材20Aとが不用意に分離してしまうことがない。 Then, the wire connecting member 30, in which the pressing projection 39 of the insertion piece 37 is retained by the retaining piece 21 of the terminal connecting member 20A, is temporarily slidable relative to the terminal connecting member 20A in the insertion direction. The assembled terminal 40A is constructed. That is, the terminal 40A housed in the terminal housing chamber 18 of the connector assembly 110A constitutes the connector 110 in which the wire connecting member 30 is temporarily attached to the terminal connecting member 20A. The connector 110 in which the wire connection member 30 is temporarily attached to the terminal connection member 20A prevents the wire connection member 30 and the terminal connection member 20A from being separated inadvertently during handling such as transportation. .

次に、図12に示すように、相手側ハウジング52の嵌合空間58内にコネクタ110のハウジング12が嵌入される。この際、電線60の端末に接続された電線接続部材30は、挿入片37の押圧突起39が端子接続部材20Aの抜け止め片21に抜け止め係止されている。そこで、端子40Aの電線接続部材30は、コネクタ110から不用意に抜け落ちてしまうことがなく、コネクタの嵌合作業性がよい。 Next, as shown in FIG. 12, the housing 12 of the connector 110 is fitted into the mating space 58 of the mating housing 52 . At this time, the wire connection member 30 connected to the end of the wire 60 has the pressing protrusion 39 of the insertion piece 37 retained by the retaining piece 21 of the terminal connection member 20A. Therefore, the wire connection member 30 of the terminal 40A is prevented from accidentally falling out of the connector 110, and the fitting workability of the connector is excellent.

コネクタ110と相手側コネクタ50との嵌合過程では、ハウジング12の端子挿入口13から端子収容室18に挿入された相手側端子70のタブ77が、端子本体部22内に挿入され、端子バネ25を弾性変形させる。そして、図13に示したように、コネクタ110と相手側コネクタ50との嵌合が完了すると、端子バネ25の弾性変形による復元力により、相手側端子70のタブ77と端子接続部材20Aの端子バネ25が接触する。 In the mating process of the connector 110 and the mating connector 50, the tab 77 of the mating terminal 70 inserted into the terminal receiving chamber 18 from the terminal insertion opening 13 of the housing 12 is inserted into the terminal body portion 22, and the terminal spring is pressed. 25 is elastically deformed. As shown in FIG. 13, when the mating of the connector 110 and the mating connector 50 is completed, the elastic deformation of the terminal spring 25 causes the tab 77 of the mating terminal 70 and the terminal of the terminal connecting member 20A to be pulled together. Spring 25 comes into contact.

次に、電線接続部材30の挿入片37が端子本体部22内にさらに挿入されることで、押圧突起39は端子バネ25の湾曲部28を押し上げながら通過する。そして、図14に示すように、端子接続部材20Aと電線接続部材30との結合が完了すると、押圧突起39は端子バネ25の傾斜部26に達する。このように、端子接続部材20Aと電線接続部材30とは、互いの結合が完了することで、一体的に連結されると共に電気的に接続されて本組み付け状態の端子40Aになる。 Next, the insertion piece 37 of the wire connection member 30 is further inserted into the terminal main body 22 , so that the pressing protrusion 39 passes while pushing up the curved portion 28 of the terminal spring 25 . Then, as shown in FIG. 14, when the connection between the terminal connection member 20A and the wire connection member 30 is completed, the pressing protrusion 39 reaches the inclined portion 26 of the terminal spring 25. As shown in FIG. In this manner, the terminal connection member 20A and the wire connection member 30 are integrally connected and electrically connected by completing their mutual coupling to form the fully assembled terminal 40A.

端子接続部材20Aと電線接続部材30との結合が完了して端子バネ25の傾斜部26に係合した挿入片37の押圧突起39は、端子バネ25の傾斜部26を押圧する。そして、端子バネ25の弾性変形による復元力と、端子バネ25の傾斜部26を押圧する押圧突起39の押圧力とにより、相手側端子70のタブ77と端子接続部材20Aの端子バネ25とが接触する。
そこで、相手側端子70は、タブ77が端子接続部材20Aにおける端子バネ25と接触凸部27とに挟持される状態で、端子40Aに電気的に接続される。
After the connection between the terminal connection member 20A and the wire connection member 30 is completed, the pressing protrusion 39 of the insertion piece 37 engaged with the inclined portion 26 of the terminal spring 25 presses the inclined portion 26 of the terminal spring 25 . Then, the tab 77 of the mating terminal 70 and the terminal spring 25 of the terminal connection member 20A are pulled together by the restoring force due to the elastic deformation of the terminal spring 25 and the pressing force of the pressing projection 39 pressing the inclined portion 26 of the terminal spring 25. Contact.
Therefore, the mating terminal 70 is electrically connected to the terminal 40A while the tab 77 is sandwiched between the terminal spring 25 and the contact protrusion 27 of the terminal connecting member 20A.

次に、本第2実施形態に係るコネクタ110の作用効果を説明する。
上述したように、本第2実施形態に係るコネクタ110によれば、ハウジング12の端子収容室18に収容される端子40Aは、図11に示したように、端子接続部材20Aと電線接続部材30の2部品で構成されている。
Next, functions and effects of the connector 110 according to the second embodiment will be described.
As described above, according to the connector 110 of the second embodiment, the terminals 40A accommodated in the terminal accommodating chambers 18 of the housing 12 are connected to the terminal connection member 20A and the wire connection member 30 as shown in FIG. consists of two parts.

そこで、先ずは3つの端子接続部材20Aをハウジング12の端子収容室18にそれぞれ挿入して可撓係止片15に抜け止め係止させることにより、コネクタ110のコネクタアッセンブリ110Aが組み立てられる。 Therefore, the connector assembly 110A of the connector 110 is assembled by first inserting the three terminal connection members 20A into the terminal accommodating chambers 18 of the housing 12 and locking them with the flexible locking pieces 15 to prevent them from coming off.

次に、電線60の端末に接続された電線接続部材30が、コネクタアッセンブリ110Aの端子収容室18にそれぞれ挿入される。この際、挿入片37の押圧突起39が、端子接続部材20Aにおける端子バネ25の湾曲部28と抜け止め片21との間まで挿入される。 Next, the wire connecting members 30 connected to the ends of the wires 60 are inserted into the terminal accommodating chambers 18 of the connector assembly 110A. At this time, the pressing protrusion 39 of the insertion piece 37 is inserted between the curved portion 28 of the terminal spring 25 and the retainer piece 21 in the terminal connection member 20A.

そして、電線接続部材30が端子接続部材20Aに対して挿入方向に相対的なスライドが可能な仮組み付け状態となった端子40Aが構成される。即ち、端子40Aがコネクタアッセンブリ110Aの端子収容室18に収容されることにより、電線接続部材30が端子接続部材20Aに対して仮組み付け状態とされたコネクタ110が組み立てられる。 Then, the terminal 40A is formed in a temporarily assembled state in which the wire connection member 30 can slide relative to the terminal connection member 20A in the insertion direction. That is, the connector 110 is assembled in which the wire connection member 30 is temporarily attached to the terminal connection member 20A by accommodating the terminal 40A in the terminal accommodation chamber 18 of the connector assembly 110A.

そこで、端子40Aの電線接続部材30が端子接続部材20Aに対して仮組み付け状態とされたコネクタ110は、運搬などにより取り扱う際、電線接続部材30と端子接続部材20Aとが不用意に分離してしまうのを防止できる。 Therefore, in the connector 110 in which the wire connection member 30 of the terminal 40A is temporarily attached to the terminal connection member 20A, the wire connection member 30 and the terminal connection member 20A are inadvertently separated from each other during transportation. You can prevent it from slipping.

次に、図12に示したように、コネクタ110が、相手側コネクタ50に嵌合される。この際、相手側端子70のタブ77が、端子接続部材20Aの端子本体部22内に挿入されて端子バネ25を弾性変形させる。そこで、端子バネ25の弾性変形による復元力により、相手側端子70のタブ77と端子接続部材20Aの端子バネ25が接触する。 Next, as shown in FIG. 12, connector 110 is mated with mating connector 50 . At this time, the tab 77 of the mating terminal 70 is inserted into the terminal body portion 22 of the terminal connecting member 20A to elastically deform the terminal spring 25 . Therefore, the tab 77 of the mating terminal 70 and the terminal spring 25 of the terminal connecting member 20A come into contact with each other due to the restoring force due to the elastic deformation of the terminal spring 25 .

即ち、図13に示したように、端子接続部材20Aの端子本体部22内に挿入される相手側端子70のタブ77に対しては、端子バネ25の弾性変形による復元力だけが作用し、端子接続部材20Aの端子本体部22内に相手側端子70のタブ77を挿入する挿入力が高くなるのを抑えることができる。そのため、コネクタ110と相手側コネクタ50とを嵌合するコネクタ嵌合力も、高くなるのを抑えることができる。 That is, as shown in FIG. 13, only the restoring force due to the elastic deformation of the terminal spring 25 acts on the tab 77 of the mating terminal 70 inserted into the terminal body portion 22 of the terminal connection member 20A. It is possible to suppress an increase in the insertion force for inserting the tab 77 of the mating terminal 70 into the terminal body portion 22 of the terminal connection member 20A. Therefore, it is possible to prevent the connector fitting force for fitting the connector 110 and the mating connector 50 from increasing.

さらに、コネクタ110が相手側コネクタ50に嵌合される際、電線60の端末に接続された電線接続部材30は、挿入片37の押圧突起39が端子接続部材20Aの抜け止め片21に抜け止め係止されている。そこで、端子40Aの電線接続部材30は、コネクタ嵌合作業中にコネクタ110から不用意に抜け落ちてしまうことがなく、コネクタの嵌合作業性がよい。 Furthermore, when the connector 110 is fitted to the mating connector 50, the wire connection member 30 connected to the end of the wire 60 is prevented from slipping off by the pressing protrusion 39 of the insertion piece 37 and the stopper piece 21 of the terminal connection member 20A. Locked. Therefore, the wire connecting member 30 of the terminal 40A is prevented from accidentally falling out of the connector 110 during the connector fitting operation, and the fitting workability of the connector is excellent.

そして、電線接続部材30の挿入片37が端子本体部22内にさらに挿入されることで、押圧突起39は端子バネ25の湾曲部28を押し上げながら通過する。そして、図14に示すように、端子接続部材20Aと電線接続部材30との結合が完了すると、押圧突起39は端子バネ25の傾斜部26に達する。端子バネ25の傾斜部26に係合した挿入片37の押圧突起39は、端子バネ25の傾斜部26を押圧する。 By further inserting the insertion piece 37 of the wire connection member 30 into the terminal main body 22 , the pressing protrusion 39 pushes up the curved portion 28 of the terminal spring 25 and passes through. Then, as shown in FIG. 14, when the connection between the terminal connection member 20A and the wire connection member 30 is completed, the pressing protrusion 39 reaches the inclined portion 26 of the terminal spring 25. As shown in FIG. The pressing protrusion 39 of the insertion piece 37 engaged with the inclined portion 26 of the terminal spring 25 presses the inclined portion 26 of the terminal spring 25 .

即ち、端子接続部材20Aにおける端子バネ25と接触凸部27とに挟持される相手側端子70のタブ77に対しては、端子バネ25の弾性変形による復元力と、端子バネ25の傾斜部26を押圧する押圧突起39の押圧力とが作用し、相手側端子70のタブ77と端子接続部材20Aの端子バネ25とは強く接触することができる。 That is, the tab 77 of the mating terminal 70 sandwiched between the terminal spring 25 and the contact projection 27 of the terminal connection member 20A is subjected to the restoring force due to the elastic deformation of the terminal spring 25 and the inclined portion 26 of the terminal spring 25. The tab 77 of the mating terminal 70 and the terminal spring 25 of the terminal connection member 20A can strongly contact each other.

そこで、3つの電線接続部材30がコネクタ110の端子接続部材20Aにそれぞれ接続されて組み立てられた嵌合コネクタ101は、端子40Aと相手側端子70とのガタ付きによる端子バネ25とタブ77との間での微摺動摩耗が抑制される。この微摺動摩耗の抑制により、微摺動摩耗により生じる摩耗粉が端子バネ25とタブ77との間に介在してしまうことが防止される。このため、端子40Aと相手側端子70の電気接続信頼性が低下することを抑制できる。
従って、本第2実施形態に係るコネクタ110によれば、コネクタ嵌合力が高くなるのを抑えつつ、端子40Aの微摺動摩耗を抑制することができる。
Therefore, in the mating connector 101 assembled by connecting the three wire connection members 30 to the terminal connection members 20A of the connector 110, the terminal springs 25 and the tabs 77 become loose due to the looseness between the terminals 40A and the mating terminals 70. Sliding wear between them is suppressed. Suppression of this micro-sliding wear prevents abrasion dust generated by the micro-sliding wear from intervening between the terminal spring 25 and the tab 77 . Therefore, it is possible to suppress the deterioration of the electrical connection reliability between the terminal 40A and the mating terminal 70 .
Therefore, according to the connector 110 according to the second embodiment, it is possible to suppress fine sliding wear of the terminals 40A while suppressing an increase in the connector fitting force.

図15は本発明の第3実施形態に係るコネクタ210のコネクタアッセンブリ210Aに、電線接続部材30が挿入される状態を示す縦断面図、図16は、図15に示したコネクタアッセンブリ210Aと相手側コネクタ50との嵌合途中状態を示す縦断面図である。なお、本第3実施形態に係るコネクタ210は、端子40に代えて端子40Bが用いられた以外は上記第1実施形態のコネクタ10と同様の構成であるので、同様の構成部材には同符号を付して詳細な説明を省略する。 15 is a longitudinal sectional view showing a state in which the wire connecting member 30 is inserted into the connector assembly 210A of the connector 210 according to the third embodiment of the present invention, and FIG. 16 is the connector assembly 210A shown in FIG. 5 is a longitudinal sectional view showing a state in the middle of fitting with the connector 50. FIG. Note that the connector 210 according to the third embodiment has the same configuration as the connector 10 of the first embodiment except that the terminal 40B is used instead of the terminal 40, so the same reference numerals are used for the same constituent members. and detailed description is omitted.

本第3実施形態に係るコネクタ210の端子40Bは、図15に示すように、端子接続部材20Bと電線接続部材30の2部品で構成されている。
端子接続部材20Bは、端子本体部22内に設けられた端子バネ25と、抜け止め片21Aと、スライド防止片29とを有する。そして、端子接続部材20Bがハウジング12の端子収容室18に収容されることで、コネクタ210のコネクタアッセンブリ210Aが構成される。
As shown in FIG. 15, the terminal 40B of the connector 210 according to the third embodiment is composed of two parts, a terminal connecting member 20B and a wire connecting member 30. As shown in FIG.
The terminal connection member 20B has a terminal spring 25 provided inside the terminal main body 22, a retaining piece 21A, and a slide preventing piece 29. As shown in FIG. A connector assembly 210A of the connector 210 is constructed by housing the terminal connection member 20B in the terminal housing chamber 18 of the housing 12. As shown in FIG.

抜け止め片21Aは、端子本体部22を構成する側壁部である側壁22cに切り起こし形成されて先端が内方へ突出する矩形状の突出片である。抜け止め片21Aは、端子接続部材20Bの端子本体部22内に電線接続部材30の挿入片37が挿入された際、挿入片37の押圧突起39を端子バネ25の湾曲部28より後方位置で抜け止め係止する。 The retaining piece 21A is a rectangular protruding piece formed by cutting and raising a side wall 22c, which is a side wall portion of the terminal body portion 22, and protruding inward at the tip. When the insertion piece 37 of the wire connection member 30 is inserted into the terminal main body portion 22 of the terminal connection member 20B, the retaining piece 21A presses the pressing projection 39 of the insertion piece 37 at a position behind the curved portion 28 of the terminal spring 25. Lock it to prevent it from coming off.

スライド防止片29は、端子バネ25に対向する上壁22bに切り起こし形成されて先端が内方へ突出する矩形状の突出片であり、抜け止め片21Aよりも突出位置が端子本体部22の前方側とされる。スライド防止片29は、抜け止め片21Aにより抜け止め係止された電線接続部材30の挿入片37が挿入方向へ移動した際には、押圧突起39と係合して押圧突起39が端子バネ25の傾斜部26に抜け止め係止されるのを阻止する。また、スライド防止片29は、コネクタ210と相手側コネクタ50とが嵌合された際には、端子本体部22内に挿入された相手側端子70のタブ77によって押圧突起39と係合不可能な状態に弾性変形される。 The slide prevention piece 29 is a rectangular protruding piece that is formed by cutting and raising the upper wall 22b facing the terminal spring 25 and protruding inward at its tip. Front side. When the insertion piece 37 of the wire connection member 30 locked by the retaining piece 21A moves in the insertion direction, the slide preventing piece 29 engages with the pressing projection 39 so that the pressing projection 39 is held by the terminal spring 25. to prevent it from being retained by the inclined portion 26 of the . Further, when the connector 210 and the mating connector 50 are mated, the slide preventing piece 29 cannot be engaged with the pressing projection 39 by the tab 77 of the mating terminal 70 inserted into the terminal main body 22. elastically deformed into a

そこで、図16に示すように、コネクタアッセンブリ210Aの端子収容室18に挿入された電線接続部材30は、端子接続部材20Bの抜け止め片21及びスライド防止片29によって、挿入片37の押圧突起39が端子接続部材20Bから抜け止め係止されると共に端子バネ25の傾斜部26に不用意に抜け止め係止されるのを阻止される。即ち、電線接続部材30は、端子接続部材20Bに対して不用意に結合することなく挿入方向に相対的なスライドが可能な仮保持状態で端子40Bを構成することができる。 Therefore, as shown in FIG. 16, the wire connecting member 30 inserted into the terminal receiving chamber 18 of the connector assembly 210A is pushed by the pressing protrusion 39 of the insertion piece 37 by the retaining piece 21 and the slide preventing piece 29 of the terminal connecting member 20B. is retained from the terminal connection member 20B and is prevented from being accidentally retained by the inclined portion 26 of the terminal spring 25. As shown in FIG. That is, the wire connection member 30 can configure the terminal 40B in a temporary holding state in which the wire connection member 30 can be relatively slid in the insertion direction without being inadvertently coupled to the terminal connection member 20B.

即ち、電線接続部材30がコネクタアッセンブリ210Aの端子収容室18に挿入されて、仮保持状態として端子接続部材20Bに組み付けられることで、コネクタアッセンブリ210Aは端子40Bを端子収容室18に収容したコネクタ210となる。 That is, the wire connecting member 30 is inserted into the terminal accommodating chamber 18 of the connector assembly 210A and assembled to the terminal connecting member 20B in a temporarily held state, whereby the connector assembly 210A is configured as the connector 210 with the terminal 40B accommodated in the terminal accommodating chamber 18. becomes.

次に、図15~図19を参照しながら上記コネクタ210と相手側コネクタ50とを嵌合する嵌合コネクタ201の組立手順を説明する。
図17は図16に示した電線接続部材30の挿入片37が端子接続部材20Bの抜け止め片21Aにより抜け止め係止され、挿入片37の押圧突起39が端子接続部材20Bの端子バネ25により抜け止め係止されるのを端子接続部材20Bのスライド防止片29により阻止された状態を示す要部拡大断面図、図18は図17に示した端子接続部材20Bのスライド防止片29が、相手側端子70のタブ77により挿入片37の押圧突起39と係合不可能な状態に弾性変形された状態を示す要部拡大断面図、図19は、図18に示した電線接続部材30の挿入片37が、端子接続部材20Bの端子バネ25により抜け止め係止された状態を示す要部拡大断面図である。
Next, the procedure for assembling the fitting connector 201 for fitting the connector 210 and the mating connector 50 will be described with reference to FIGS. 15 to 19. FIG.
FIG. 17 shows that the insertion piece 37 of the wire connection member 30 shown in FIG. FIG. 18 is an enlarged cross-sectional view of a main part showing a state in which the anti-slip piece 29 of the terminal connection member 20B prevents the terminal connection member 20B from being locked. FIG. FIG. 19 is an enlarged cross-sectional view of a main part showing a state in which the tab 77 of the side terminal 70 is elastically deformed so as not to be able to engage with the pressing projection 39 of the insertion piece 37. FIG. FIG. 4 is an enlarged cross-sectional view of a main part showing a state in which a piece 37 is retained by a terminal spring 25 of a terminal connection member 20B.

先ず、図15に示したように、電線60の端末に接続された電線接続部材30が、コネクタアッセンブリ210Aの端子収容室18にそれぞれ挿入される。そして、挿入片37の押圧突起39が端子接続部材20Bの抜け止め片21Aを押し広げながら通過し、押圧突起39はスライド防止片29と抜け止め片21Aとの間まで挿入される。 First, as shown in FIG. 15, the wire connecting members 30 connected to the ends of the wires 60 are inserted into the terminal accommodating chambers 18 of the connector assembly 210A. Then, the pressing protrusion 39 of the insertion piece 37 passes while spreading the retaining piece 21A of the terminal connection member 20B, and the pressing protrusion 39 is inserted between the slide preventing piece 29 and the retaining piece 21A.

すると、端子接続部材20Bの抜け止め片21及びスライド防止片29によって挿入片37の押圧突起39が抜け止め係止されると共に端子バネ25の傾斜部26に不用意に抜け止め係止されるのを阻止された電線接続部材30は、端子接続部材20Bに対して不用意に結合することなく挿入方向に相対的なスライドが可能な仮保持状態となった端子40Bを構成する。即ち、コネクタアッセンブリ210Aの端子収容室18に収容された端子40Bは、電線接続部材30が端子接続部材20Bに対して仮保持状態とされたコネクタ210を構成する。この電線接続部材30が端子接続部材20Bに対して仮保持状態とされたコネクタ210は、運搬などにより取り扱う際、電線接続部材30と端子接続部材20Bとが不用意に分離してしまったり、不用意に結合してしまったりすることがない。 As a result, the pressing projection 39 of the insertion piece 37 is retained by the retaining piece 21 and the slide preventing piece 29 of the terminal connection member 20B, and is also retained by the inclined portion 26 of the terminal spring 25 to prevent accidental removal. The wire connection member 30 blocked from the above constitutes a terminal 40B in a temporarily held state that allows relative sliding in the insertion direction without being inadvertently coupled to the terminal connection member 20B. That is, the terminal 40B housed in the terminal housing chamber 18 of the connector assembly 210A constitutes the connector 210 in which the wire connecting member 30 is temporarily held with respect to the terminal connecting member 20B. When the connector 210 in which the wire connection member 30 is temporarily held with respect to the terminal connection member 20B is handled during transportation, the wire connection member 30 and the terminal connection member 20B may be separated from each other inadvertently. There is no preparatory combination.

次に、図16に示すように、相手側ハウジング52の嵌合空間58内にコネクタ210のハウジング12が嵌入される。この際、電線60の端末に接続された電線接続部材30は、挿入片37の押圧突起39が端子接続部材20Bの抜け止め片21及びスライド防止片29によって仮保持状態とされている。そこで、端子40Bの電線接続部材30は、コネクタ110から不用意に抜け落ちてしまったり、不用意に結合されてしまったりすることがなく、コネクタの嵌合作業性がよい。 Next, as shown in FIG. 16, the housing 12 of the connector 210 is fitted into the fitting space 58 of the mating housing 52 . At this time, the wire connecting member 30 connected to the end of the wire 60 is temporarily held by the pressing projection 39 of the insertion piece 37 by the retaining piece 21 and the slide preventing piece 29 of the terminal connecting member 20B. Therefore, the wire connection member 30 of the terminal 40B is prevented from being accidentally pulled off from the connector 110 or unintentionally coupled, and the fitting workability of the connector is excellent.

コネクタ210と相手側コネクタ50との嵌合過程では、図17に示すように、ハウジング12の端子挿入口13から端子収容室18に挿入された相手側端子70のタブ77が、端子本体部22内に挿入され、端子バネ25を弾性変形させる。 In the process of fitting the connector 210 and the mating connector 50, as shown in FIG. inside to elastically deform the terminal spring 25 .

そして、図18に示したように、コネクタ210と相手側コネクタ50との嵌合が完了すると、スライド防止片29は、端子本体部22内に挿入された相手側端子70のタブ77によって押圧突起39と係合不可能な状態に弾性変形される。また、端子バネ25の弾性変形による復元力により、相手側端子70のタブ77と端子接続部材20Bの端子バネ25が接触する。 Then, as shown in FIG. 18, when the connector 210 and the mating connector 50 are completely mated, the slide preventing piece 29 is pressed by the tab 77 of the mating terminal 70 inserted into the terminal main body 22 . 39 is elastically deformed so that it cannot be engaged. Further, the tab 77 of the mating terminal 70 and the terminal spring 25 of the terminal connection member 20B are brought into contact with each other due to the restoring force due to the elastic deformation of the terminal spring 25 .

次に、電線接続部材30の挿入片37が端子本体部22内にさらに挿入されることで、押圧突起39は端子バネ25の湾曲部28を押し上げながら通過する。そして、図19に示すように、端子接続部材20Bと電線接続部材30との結合が完了すると、押圧突起39は端子バネ25の傾斜部26に達する。このように、端子接続部材20Bと電線接続部材30とは、互いの結合が完了することで、一体的に連結されると共に電気的に接続されて本組み付け状態の端子40Bになる。 Next, the insertion piece 37 of the wire connection member 30 is further inserted into the terminal main body 22 , so that the pressing protrusion 39 passes while pushing up the curved portion 28 of the terminal spring 25 . 19, when the connection between the terminal connection member 20B and the wire connection member 30 is completed, the pressing projection 39 reaches the inclined portion 26 of the terminal spring 25. As shown in FIG. In this manner, the terminal connection member 20B and the wire connection member 30 are integrally connected and electrically connected by completing their mutual coupling to form the fully assembled terminal 40B.

端子接続部材20Bと電線接続部材30との結合が完了して端子バネ25の傾斜部26に係合した挿入片37の押圧突起39は、端子バネ25の傾斜部26を押圧する。そして、端子バネ25の弾性変形による復元力と、端子バネ25の傾斜部26を押圧する押圧突起39の押圧力とにより、相手側端子70のタブ77と端子接続部材20Bの端子バネ25とが接触する。
そこで、相手側端子70は、タブ77が端子接続部材20Bにおける端子バネ25と接触凸部27とに挟持される状態で、端子40Bに電気的に接続される。
After the connection between the terminal connection member 20B and the wire connection member 30 is completed, the pressing protrusion 39 of the insertion piece 37 engaged with the inclined portion 26 of the terminal spring 25 presses the inclined portion 26 of the terminal spring 25 . Then, the tab 77 of the mating terminal 70 and the terminal spring 25 of the terminal connecting member 20B are pulled together by the restoring force due to the elastic deformation of the terminal spring 25 and the pressing force of the pressing projection 39 pressing the inclined portion 26 of the terminal spring 25. Contact.
Therefore, the mating terminal 70 is electrically connected to the terminal 40B with the tab 77 sandwiched between the terminal spring 25 and the contact projection 27 of the terminal connecting member 20B.

次に、本第3実施形態に係るコネクタ210の作用効果を説明する。
上述したように、本第3実施形態に係るコネクタ210によれば、ハウジング12の端子収容室18に収容される端子40Bは、図15に示したように、端子接続部材20Bと電線接続部材30の2部品で構成されている。
Next, functions and effects of the connector 210 according to the third embodiment will be described.
As described above, according to the connector 210 according to the third embodiment, the terminals 40B accommodated in the terminal accommodating chambers 18 of the housing 12 are separated from the terminal connection member 20B and the wire connection member 30 as shown in FIG. consists of two parts.

そこで、先ずは3つの端子接続部材20Bをハウジング12の端子収容室18にそれぞれ挿入して可撓係止片15に抜け止め係止させることにより、コネクタ210のコネクタアッセンブリ210Aが組み立てられる。 First, the connector assembly 210A of the connector 210 is assembled by inserting the three terminal connection members 20B into the terminal accommodating chambers 18 of the housing 12 and locking them with the flexible locking pieces 15 to prevent them from coming off.

次に、電線60の端末に接続された電線接続部材30が、コネクタアッセンブリ210Aの端子収容室18にそれぞれ挿入される。この際、挿入片37の押圧突起39が、端子接続部材20Bにおけるスライド防止片29と抜け止め片21との間まで挿入される。 Next, the wire connecting members 30 connected to the ends of the wires 60 are inserted into the terminal accommodating chambers 18 of the connector assembly 210A. At this time, the pressing protrusion 39 of the insertion piece 37 is inserted between the slide preventing piece 29 and the retaining piece 21 in the terminal connection member 20B.

そして、電線接続部材30が端子接続部材20Bに対して不用意に結合することなく挿入方向に相対的なスライドが可能な仮保持状態となった端子40Bが構成される。即ち、端子40Bがコネクタアッセンブリ210Aの端子収容室18に収容されることにより、電線接続部材30が端子接続部材20Bに対して仮保持状態とされたコネクタ210が組み立てられる。 Thus, the terminal 40B is formed in a temporarily held state in which the wire connection member 30 is relatively slidable in the insertion direction without being inadvertently coupled to the terminal connection member 20B. That is, the connector 210 is assembled in which the wire connecting member 30 is temporarily held with respect to the terminal connecting member 20B by housing the terminal 40B in the terminal housing chamber 18 of the connector assembly 210A.

そこで、端子40Bの電線接続部材30が端子接続部材20Bに対して仮保持状態とされたコネクタ210は、運搬などにより取り扱う際、電線接続部材30と端子接続部材20Bとが不用意に分離してしまったり、不用意に結合してしまったりするのを防止できる。 Therefore, in the connector 210 in which the wire connection member 30 of the terminal 40B is temporarily held with respect to the terminal connection member 20B, the wire connection member 30 and the terminal connection member 20B are inadvertently separated during transportation. It is possible to prevent them from being put together or unintentionally being combined.

次に、図16に示したように、コネクタ210が、相手側コネクタ50に嵌合される。この際、相手側端子70のタブ77が、端子接続部材20Bの端子本体部22内に挿入されて端子バネ25を弾性変形させる。そこで、端子バネ25の弾性変形による復元力により、相手側端子70のタブ77と端子接続部材20Bの端子バネ25が接触する。 Next, as shown in FIG. 16, connector 210 is mated with mating connector 50 . At this time, the tab 77 of the mating terminal 70 is inserted into the terminal body portion 22 of the terminal connecting member 20B to elastically deform the terminal spring 25 . Therefore, the tab 77 of the mating terminal 70 and the terminal spring 25 of the terminal connection member 20B come into contact with each other due to the restoring force due to the elastic deformation of the terminal spring 25 .

即ち、図17及び図18に示したように、端子接続部材20Bの端子本体部22内に挿入される相手側端子70のタブ77に対しては、端子バネ25の弾性変形による復元力だけが作用し、端子接続部材20Bの端子本体部22内に相手側端子70のタブ77を挿入する挿入力が高くなるのを抑えることができる。そのため、コネクタ210と相手側コネクタ50とを嵌合するコネクタ嵌合力も、高くなるのを抑えることができる。 That is, as shown in FIGS. 17 and 18, only the restoring force due to the elastic deformation of the terminal spring 25 is applied to the tab 77 of the mating terminal 70 inserted into the terminal body portion 22 of the terminal connection member 20B. As a result, the insertion force for inserting the tab 77 of the mating terminal 70 into the terminal main body portion 22 of the terminal connection member 20B can be suppressed from increasing. Therefore, it is possible to prevent the connector fitting force for fitting the connector 210 and the mating connector 50 from increasing.

さらに、コネクタ210が相手側コネクタ50に嵌合される際、電線60の端末に接続された電線接続部材30は、挿入片37の押圧突起39が端子接続部材20Bの抜け止め片21に抜け止め係止されると共に端子バネ25の傾斜部26に不用意に抜け止め係止されるのを阻止されている。そこで、端子40Bの電線接続部材30は、コネクタ嵌合作業中にコネクタ210から不用意に抜け落ちてしまうことがなく、コネクタの嵌合作業性がよい。 Furthermore, when the connector 210 is fitted to the mating connector 50, the wire connection member 30 connected to the end of the wire 60 is prevented from slipping off by the pressing projection 39 of the insertion piece 37 and the stopper piece 21 of the terminal connection member 20B. As well as being locked, the terminal spring 25 is prevented from being unintentionally retained by the slanted portion 26 of the terminal spring 25 . Therefore, the wire connection member 30 of the terminal 40B is not accidentally pulled off from the connector 210 during the connector fitting work, and the fitting workability of the connector is excellent.

そして、電線接続部材30の挿入片37が端子本体部22内にさらに挿入されることで、押圧突起39は端子バネ25の湾曲部28を押し上げながら通過する。そして、図19に示すように、端子接続部材20Bと電線接続部材30との結合が完了すると、押圧突起39は端子バネ25の傾斜部26に達する。端子バネ25の傾斜部26に係合した挿入片37の押圧突起39は、端子バネ25の傾斜部26を押圧する。 By further inserting the insertion piece 37 of the wire connection member 30 into the terminal main body 22 , the pressing protrusion 39 pushes up the curved portion 28 of the terminal spring 25 and passes through. 19, when the connection between the terminal connection member 20B and the wire connection member 30 is completed, the pressing projection 39 reaches the inclined portion 26 of the terminal spring 25. As shown in FIG. The pressing protrusion 39 of the insertion piece 37 engaged with the inclined portion 26 of the terminal spring 25 presses the inclined portion 26 of the terminal spring 25 .

即ち、端子接続部材20Bにおける端子バネ25と接触凸部27とに挟持される相手側端子70のタブ77に対しては、端子バネ25の弾性変形による復元力と、端子バネ25の傾斜部26を押圧する押圧突起39の押圧力とが作用し、相手側端子70のタブ77と端子接続部材20Bの端子バネ25とは強く接触することができる。 That is, the tab 77 of the mating terminal 70 sandwiched between the terminal spring 25 and the contact protrusion 27 of the terminal connection member 20B is subjected to the restoring force due to the elastic deformation of the terminal spring 25 and the inclined portion 26 of the terminal spring 25. The tab 77 of the mating terminal 70 and the terminal spring 25 of the terminal connecting member 20B can strongly contact each other.

そこで、3つの電線接続部材30がコネクタ210の端子接続部材20Bにそれぞれ接続されて組み立てられた嵌合コネクタ201は、端子40Bと相手側端子70とのガタ付きによる端子バネ25とタブ77との間での微摺動摩耗が抑制される。この微摺動摩耗の抑制により、微摺動摩耗により生じる摩耗粉が端子バネ25とタブ77との間に介在してしまうことが防止される。このため、端子40Bと相手側端子70の電気接続信頼性が低下することを抑制できる。
従って、本第3実施形態に係るコネクタ210によれば、コネクタ嵌合力が高くなるのを抑えつつ、端子40Bの微摺動摩耗を抑制することができる。
Therefore, in the mating connector 201 assembled by connecting the three wire connection members 30 to the terminal connection members 20B of the connector 210, the terminal springs 25 and the tabs 77 become loose due to the looseness between the terminals 40B and the mating terminals 70. Sliding wear between them is suppressed. Suppression of this micro-sliding wear prevents abrasion dust generated by the micro-sliding wear from intervening between the terminal spring 25 and the tab 77 . Therefore, it is possible to suppress the deterioration of the electrical connection reliability between the terminal 40B and the mating terminal 70 .
Therefore, according to the connector 210 according to the third embodiment, it is possible to suppress fine sliding wear of the terminals 40B while suppressing an increase in the connector fitting force.

例えば、上記実施形態では、相手側端子のタブとして雄端子である相手側端子70のタブ77を例に説明したが、これに限定されず相手側ハウジングに圧入されたバスバ端子とすることもできる。 For example, in the above embodiment, the tab 77 of the mating terminal 70, which is a male terminal, was described as an example of the tab of the mating terminal. .
