Description

本発明は、コネクタの組立方法に関する。 The present invention relates to a method for assembling a connector.

一般に、複数の電気部品や電機機器等において、ケーブルを着脱自在に接続するためのコネクタが知られている（特許文献１参照）。
図１９に示すコネクタ５０１は、同軸ケーブル５０３の端部にそれぞれ取り付けられて軸方向に延出する接続部５０５に対し屈曲する端子部５０７によりＬ字型となる第１接続端子５０９及び第２接続端子５１１と、ハウジング５２３と、カバー５２５と、隔壁部材５３１と、を有する。ハウジング５２３は、接続部５０５を収容する収容凹部５１３が形成される本体部５１５と、本体部５１５に一体に形成されている突設部５２１とから成り、一体に形成されている。突設部５２１は、本体部５１５の先端部から相手側コネクタへの嵌合方向に突出形成されると共に端子部５０７を収容する第１収容孔部５１７及び第２収容孔部５１９が収容凹部５１３に連通形成されている。カバー５２５及び隔壁部材５３１は、収容凹部５１３、第１収容孔部５１７並びに第２収容孔部５１９を反嵌合方向から閉塞する。ハウジング５２３の第１収容孔部５１７及び第２収容孔部５１９は、反嵌合方向から挿入された端子部５０７を同軸ケーブル５０３の軸方向に位置決めして収容する。また、カバー５２５及び隔壁部材５３１は、第１収容孔部５１７及び第２収容孔部５１９に収容された端子部５０７の反嵌合方向側端部に当接し、端子部５０７の反嵌合方向への動きを拘束する支持部５２７及び支持部５２９を有する。 In general, connectors for detachably connecting cables to a plurality of electric parts, electric devices, and the like are known (see Patent Document 1).
The connector 501 shown in FIG. 19 has a first connection terminal 509 and a second connection that are L-shaped by a terminal portion 507 that is attached to the end of the coaxial cable 503 and bends with respect to the connection portion 505 that extends in the axial direction. It has a terminal 511, a housing 523, a cover 525, and a partition member 531. The housing 523 is integrally formed of a main body portion 515 in which a storage recess 513 for accommodating the connection portion 505 is formed and a projecting portion 521 integrally formed in the main body portion 515. The protrusion 521 is formed so as to project from the tip of the main body 515 in the fitting direction to the mating connector, and the first accommodating hole 517 and the second accommodating hole 519 accommodating the terminal portion 507 are accommodating recesses 513. It is formed in communication with. The cover 525 and the partition wall member 531 close the accommodating recess 513, the first accommodating hole 517, and the second accommodating hole 519 from the anti-fitting direction. The first accommodating hole 517 and the second accommodating hole 519 of the housing 523 accommodate the terminal portion 507 inserted from the anti-fitting direction by positioning it in the axial direction of the coaxial cable 503. Further, the cover 525 and the partition wall member 531 abut on the anti-fitting direction side end portion of the terminal portion 507 housed in the first accommodating hole portion 517 and the second accommodating hole portion 519, and the anti-fitting direction of the terminal portion 507. It has a support portion 527 and a support portion 529 that restrain the movement to.

このようなコネクタ５０１を組み立てるには、まず、作業者は、ハウジング５２３の収容凹部５１３及び第１収容孔部５１７に対し、上方から第１接続端子５０９を臨ませ、第１接続端子５０９の端子部５０７を第１収容孔部５１７に挿入し、第１接続端子５０９の接続部５０５を収容凹部５１３に挿入する。
次に、作業者は、ハウジング５２３の各収容凹部５１３及び各第１収容孔部５１７に対し、上方から隔壁部材５３１を臨ませ、隔壁部材５３１をハウジング５２３の内部に押下げる。第１接続端子５０９は、前壁５３３と支持部５２７とにより挟持された状態で、端子部５０７が第１収容孔部５１７に保持される。
次に、作業者は、隔壁部材５３１の各隔壁側収容凹部５３５及びハウジング５２３の各第２収容孔部５１９に対し、上方から第２接続端子５１１を臨ませ、第２接続端子５１１の端子部５０７を第２収容孔部５１９に挿入し、第２接続端子５１１の接続部５０５を隔壁側収容凹部５３５に挿入する。
次に、作業者は、ハウジング５２３の上端部に対し、上方からカバー５２５を取り付ける。第２接続端子５１１は、前壁５３３と支持部５２９とにより挟持された状態で、端子部５０７が第２収容孔部５１９に保持される。これにより、コネクタ５０１の組立が完了する。 In order to assemble such a connector 501, first, the operator makes the first connection terminal 509 face the accommodating recess 513 and the first accommodating hole 517 of the housing 523 from above, and the terminal of the first connection terminal 509. The portion 507 is inserted into the first accommodating hole portion 517, and the connecting portion 505 of the first connection terminal 509 is inserted into the accommodating recess 513.
Next, the operator makes the partition wall member 531 face from above with respect to each of the housing recesses 513 and the first storage hole 517 of the housing 523, and pushes the partition wall member 531 into the housing 523. The terminal portion 507 is held in the first accommodating hole portion 517 in a state where the first connection terminal 509 is sandwiched between the front wall 533 and the support portion 527.
Next, the operator makes the second connection terminal 511 face from above with respect to each of the partition wall side accommodating recesses 535 of the partition wall member 531 and each of the second accommodating holes 519 of the housing 523, and the terminal portion of the second connection terminal 511. The 507 is inserted into the second housing hole 519, and the connection 505 of the second connection terminal 511 is inserted into the partition wall side housing recess 535.
Next, the operator attaches the cover 525 to the upper end of the housing 523 from above. The second connection terminal 511 is sandwiched between the front wall 533 and the support portion 529, and the terminal portion 507 is held in the second accommodating hole portion 519. As a result, the assembly of the connector 501 is completed.

このようなコネクタ５０１によれば、端子部５０７が、ランス部等の係止手段である突起物を有していないため、第１収容孔部５１７及び第２収容孔部５１９は、端子部５０７のみを収容可能な最小限の大きさに形成することができる。すなわち、第１収容孔部５１７及び第２収容孔部５１９は、端子部５０７を非係止状態に収容することができる。これにより、ランス部を有する接続端子（端子部）を収容する場合と比して、突設部５２１を小型化できる。 According to such a connector 501, since the terminal portion 507 does not have a protrusion which is a locking means such as a lance portion, the first accommodating hole portion 517 and the second accommodating hole portion 519 have the terminal portion 507. It can be formed to the minimum size that can accommodate only. That is, the first accommodating hole portion 517 and the second accommodating hole portion 519 can accommodate the terminal portion 507 in a non-locked state. As a result, the projecting portion 521 can be miniaturized as compared with the case where the connection terminal (terminal portion) having the lance portion is accommodated.

しかしながら、複数の端子付電線５３９及び端子付電線５４１の端末部に接続された第１接続端子５０９及び第２接続端子５１１をハウジング５２３の第１収容孔部５１７及び第２収容孔部５１９（端子収容室）に順次収容する際、後挿入の端子付電線５４１は、電線同士が結束されていなく、端部で第２接続端子５１１がフリーとなる。このため、端子付電線５４１は、取り回しによって電線同士が絡んだり、接続端子同士が接触して傷が付いたりする可能性がある。また、端子付電線５３９及び端子付電線５４１は、第１接続端子５０９及び第２接続端子５１１をハウジング５２３の端子収容に順次挿入する際、端子を識別して対応する端子収容室に挿入する必要が有り、作業性が良くない。 However, the first connection terminal 509 and the second connection terminal 511 connected to the terminal portions of the plurality of terminal-equipped electric wires 539 and the terminal-attached electric wires 541 are connected to the first accommodating hole 517 and the second accommodating hole 519 (terminals) of the housing 523. When the wires are sequentially housed in the housing chamber), the wires 541 with terminals inserted afterwards are not bundled with each other, and the second connection terminal 511 becomes free at the end. Therefore, in the electric wire 541 with terminals, there is a possibility that the electric wires may be entangled with each other or the connection terminals may come into contact with each other and be damaged due to the routing. Further, when the first connection terminal 509 and the second connection terminal 511 are sequentially inserted into the terminal accommodation of the housing 523, the terminal-attached electric wire 539 and the terminal-attached electric wire 541 need to identify the terminals and insert them into the corresponding terminal accommodation chambers. There is, and workability is not good.

A method for assembling a connector including a cover attached to the connector housing so as to cover the terminal insertion ports of the plurality of terminal accommodating chambers, wherein the wire crimping portion and the wire crimping portion in the plurality of wires with first terminals are provided. The first step in which the portion of the electric wire extending from the terminal portion connected to the electric wire crimping portion is held in the vertical groove portion in the electric wire holding portion of the cover, and the plurality of first terminals held in the cover. the first connection terminal in the attached wires, a second step of respectively inserted before SL terminal receiving chamber, seen including a third step attached, to said cover said connector housing, said connector, said first The second connection terminal, which has a shorter terminal connection portion than the connection terminal, has an electric wire with a second terminal connected to the terminal portion, respectively, and before the first step, the terminal of the second connection terminal. The connection portion includes a fourth step of inserting the connection portion into the terminal accommodating chamber of the connector housing, and in the second step, the terminal connection portion of the first connection terminal held by the cover is inserted into the terminal accommodating chamber. After being guided, the guided portion of the cover is fitted to the guide portion of the connector housing to position the connector housing, and in the first step, the spacer attached to the cover causes the first connection terminal. The first connection terminal was held by the cover so as to be sandwiched between the cover and the spacer in the mounting direction of the cover to the connector housing, and was housed in the terminal accommodating chamber in the third step. A method for assembling a connector, characterized in that the cover is attached to the connector housing so that the second connection terminal is sandwiched between the connector housing and the spacer in the attachment direction .

上記（１）に記載のコネクタの組立方法によれば、複数の第１端子付電線が、カバーの電線保持部に保持される。この際、それぞれの第１端子付電線は、電線の端末部に第１接続端子が圧着等により接続された後、接続順にカバーへ保持させることができる。そのため、複数の第１端子付電線はフリーとならず、端子同士の接触や電線同士の絡みが生じない。
カバーは、全ての第１端子付電線を保持した状態で、コネクタハウジングに取り付けられる。カバーは、コネクタハウジングに取り付けられる際、先ず、保持している第１端子付電線の第１接続端子が、端子収容室に挿入される。この際、複数の第１端子付電線は、カバーによって既に第１接続端子が所定の順に並べられているので、例えば片側から順に第１接続端子をコネクタハウジングの端子収容室へ挿入していけばよく、挿入対象の端子収容室を確認する手間が省け、挿入作業を良好に行うことができる。 According to the connector assembly method described in (1) above, a plurality of electric wires with first terminals are held by the electric wire holding portion of the cover. At this time, each electric wire with a first terminal can be held by the cover in the order of connection after the first connection terminal is connected to the terminal portion of the electric wire by crimping or the like. Therefore, the plurality of electric wires with the first terminal are not free, and the terminals do not come into contact with each other or the electric wires do not get entangled with each other.
The cover is attached to the connector housing while holding all the wires with the first terminal. When the cover is attached to the connector housing, first, the first connection terminal of the electric wire with the first terminal held is inserted into the terminal accommodating chamber. At this time, since the first connection terminals of the plurality of electric wires with first terminals are already arranged in a predetermined order by the cover, for example, if the first connection terminals are inserted into the terminal accommodating chamber of the connector housing in order from one side. It is possible to save the trouble of checking the terminal accommodating chamber to be inserted and to perform the insertion work well.

更に、上記（１）に記載のコネクタの組立方法によれば、コネクタが、第１端子付電線と、第２端子付電線とを有する。第１端子付電線の端子接続部は、第２端子付電線の端子接続部よりも長い。端子接続部が短い第２端子付電線は、第１端子付電線よりも先に端子接続部がコネクタハウジングに挿入される。端子接続部が長い第１端子付電線は、カバーに保持された状態で、第２端子付電線の後方から重ねられてコネクタハウジングへ挿入することができる。この際、第１端子付電線は、先ず、端子接続部が端子収容室の端子挿入口に挿入されて挿入案内される。挿入過程において、続けてカバーの被ガイド部がコネクタハウジングのガイド部に嵌合される。これにより、カバーは、コネクタハウジングに対して位置規制されながらコネクタハウジングに取り付けられる。カバーは、クリアランスの大きい端子接続部と端子挿入口による規制、クリアランスの小さい被ガイド部とガイド部とによる規制と、徐々に規制範囲が小さくなるので、組み付け作業を良好に行うことができる。 Further, according to the connector assembly method described in ( 1 ) above, the connector has a wire with a first terminal and a wire with a second terminal. The terminal connection portion of the electric wire with the first terminal is longer than the terminal connection portion of the electric wire with the second terminal. In the electric wire with a second terminal having a short terminal connection portion, the terminal connection portion is inserted into the connector housing before the electric wire with the first terminal. The electric wire with the first terminal having a long terminal connection portion can be stacked from the rear of the electric wire with the second terminal and inserted into the connector housing while being held by the cover. At this time, in the electric wire with the first terminal, the terminal connection portion is first inserted into the terminal insertion port of the terminal accommodating chamber to guide the insertion. In the insertion process, the guided portion of the cover is subsequently fitted into the guide portion of the connector housing. As a result, the cover is attached to the connector housing while being positioned with respect to the connector housing. As for the cover, the regulation range is gradually reduced by the regulation by the terminal connection portion and the terminal insertion port having a large clearance and the regulation by the guided portion and the guide portion having a small clearance, so that the assembly work can be performed well.

更に、上記（１）に記載のコネクタの組立方法によれば、複数の第１端子付電線が、スペーサによりカバーの電線保持部に保持される。つまり、複数の第１端子付電線が、カバーにプリセットされる。これにより、複数の第１端子付電線はフリーとならず、端子同士の接触や電線同士の絡みが生じない。
カバーは、全ての第１端子付電線を保持した状態で、コネクタハウジングに取り付けられる。カバーは、コネクタハウジングに取り付けられた際、スペーサが第２接続端子に当接する。これにより、スペーサは、端子収容室に収容された第２接続端子の抜け止めをすることができる。 Further, according to the connector assembly method described in ( 1 ) above, a plurality of electric wires with first terminals are held by spacers in the electric wire holding portion of the cover. That is, a plurality of electric wires with first terminals are preset on the cover. As a result, the plurality of electric wires with first terminals are not free, and contact between terminals and entanglement between electric wires do not occur.
The cover is attached to the connector housing while holding all the wires with the first terminal. When the cover is attached to the connector housing, the spacer abuts on the second connection terminal. As a result, the spacer can prevent the second connection terminal housed in the terminal storage chamber from coming off.

本発明に係るコネクタの組立方法によれば、電線の絡みや端子の傷付きを防止して、端子挿入作業を良好に行うことができる。 According to the connector assembly method according to the present invention, it is possible to prevent entanglement of electric wires and damage to terminals, and to perform terminal insertion work satisfactorily.

(See (a)) is sandwiched between them, and the departure from the first terminal accommodating chamber 39 is restricted. As a result, the connector 100 is assembled.

次に、上記したコネクタの組立方法の作用を説明する。
本第１実施形態に係るコネクタの組立方法では、コネクタ１００が、第１端子付電線１３と、第２端子付電線１９とを有する。第１端子付電線１３の第１端子接続部２７は、第２端子付電線１９の第２端子接続部２９よりも長い。第２端子接続部２９が短い第２端子付電線１９は、第１端子付電線１３よりも先に第２端子接続部２９がコネクタハウジング１１の第２端子収容室４１に挿入される。第１端子接続部２７が長い第１端子付電線１３は、カバー１５に保持された状態で、第２端子付電線１９の後方から重ねられてコネクタハウジング１１の第１端子収容室３９へ挿入することができる。 Next, the operation of the above-mentioned connector assembly method will be described.
In the connector assembly method according to the first embodiment, the connector 100 has a first terminal-attached electric wire 13 and a second terminal-attached electric wire 19. The first terminal connection portion 27 of the first terminal-attached electric wire 13 is longer than the second terminal connection portion 29 of the second terminal-attached electric wire 19. In the electric wire 19 with a second terminal having a short second terminal connecting portion 29, the second terminal connecting portion 29 is inserted into the second terminal accommodating chamber 41 of the connector housing 11 before the electric wire 13 with the first terminal. The electric wire 13 with a first terminal having a long first terminal connecting portion 27 is stacked from the rear of the electric wire 19 with a second terminal and inserted into the first terminal accommodating chamber 39 of the connector housing 11 while being held by the cover 15. be able to.

この際、第１端子付電線１３は、先ず、第１端子接続部２７が第１端子収容室３９の端子挿入口４３に挿入されて挿入案内される。挿入過程において、続けてカバー１５の被ガイド部５１がコネクタハウジング１１のガイド部４９に嵌合される。これにより、カバー１５は、コネクタハウジング１１に対して位置規制されながらコネクタハウジング１１に取り付けられる。カバー１５は、クリアランスの大きい第１端子接続部２７と端子挿入口４３による規制、クリアランスの小さい被ガイド部５１とガイド部４９とによる規制と、徐々に規制範囲が小さくなるので、組み付け作業を段階的に良好に行うことができる。 At this time, in the electric wire 13 with the first terminal, first, the first terminal connecting portion 27 is inserted into the terminal insertion port 43 of the first terminal accommodating chamber 39 to guide the insertion. In the insertion process, the guided portion 51 of the cover 15 is subsequently fitted into the guide portion 49 of the connector housing 11. As a result, the cover 15 is attached to the connector housing 11 while being positioned with respect to the connector housing 11. The cover 15 is regulated by the first terminal connection portion 27 having a large clearance and the terminal insertion port 43, and is regulated by the guided portion 51 and the guide portion 49 having a small clearance, and the regulation range gradually becomes smaller. Can be done well.

また、本第１実施形態のコネクタの組立方法では、複数の第１端子付電線１３が、スペーサ１７によりカバー１５の一対の縦溝部５３からなる電線保持部７７（図３の（ａ）参照）に保持される。つまり、複数の第１端子付電線１３が、カバー１５にプリセットされる。これにより、複数の第１端子付電線１３はフリーとならず、端子同士の接触や電線同士の絡みが生じない。 Further, in the method of assembling the connector of the first embodiment, a plurality of electric wires 13 with first terminals are formed of a wire holding portion 77 composed of a pair of vertical groove portions 53 of the cover 15 by a spacer 17 (see (a) in FIG. 3). Is held in. That is, a plurality of electric wires 13 with first terminals are preset on the cover 15. As a result, the plurality of wires 13 with first terminals are not free, and contact between terminals and entanglement between wires do not occur.

また、カバー１５は、全ての第１端子付電線１３を保持した状態で、コネクタハウジング１１に取り付けられる。カバー１５は、コネクタハウジング１１に取り付けられる際、スペーサ１７が第２接続端子２５に当接する。これにより、スペーサ１７は、第２端子収容室４１に収容された第２接続端子２５の抜け止めをすることができる。 Further, the cover 15 is attached to the connector housing 11 while holding all the electric wires 13 with the first terminals. When the cover 15 is attached to the connector housing 11, the spacer 17 comes into contact with the second connection terminal 25. As a result, the spacer 17 can prevent the second connection terminal 25 housed in the second terminal storage chamber 41 from coming off.

また、カバー１５は、全ての第１端子付電線１３を保持した状態で、コネクタハウジング１１に取り付けられる。カバー１５は、コネクタハウジング１１に取り付けられる際、先ず、保持している第１端子付電線１３の第１接続端子２３が、第１端子収容室３９に挿入される。この際、２本の第１端子付電線１３は、カバー１５によって既に第１接続端子２３が所定の順に並べられているので、第１接続端子２３をコネクタハウジング１１の第１端子収容室３９へ挿入すればよく、挿入対象の第１端子収容室３９を確認する手間が省け、挿入作業を良好に行うことができる。 Further, the cover 15 is attached to the connector housing 11 while holding all the electric wires 13 with the first terminals. When the cover 15 is attached to the connector housing 11, the first connection terminal 23 of the electric wire 13 with the first terminal held is first inserted into the first terminal accommodating chamber 39. At this time, since the first connection terminals 23 of the two wires 13 with first terminals are already arranged in a predetermined order by the cover 15, the first connection terminals 23 are moved to the first terminal accommodating chamber 39 of the connector housing 11. It suffices to insert it, and it is possible to save the trouble of checking the first terminal accommodating chamber 39 to be inserted and to perform the insertion work satisfactorily.

本第２実施形態に係る第１端子付電線８１は、電線８７の端末部に、第１接続端子８９が接続されている。第１接続端子８９は、導電性の良好な金属板を板金加工して形成されている。第１接続端子８９は、先端側から箱状の電気接触部９１と、導体圧着部９３と、被覆電線圧着部９５と、が順に連設されている。第１接続端子８９は、電気接触部９１が箱状に形成されることで雌端子となる。電気接触部９１の内側には、相手側コネクタ（図示略）の雄タブ端子が進入する。本第２実施形態において、電線８７は、単一の導体が絶縁被覆により覆われた単線となる。電線８７は、端末部の絶縁被覆が剥かれることで露出した導体が導体圧着部９３に圧着される。電線８７は、導体より基端側の絶縁被覆が被覆電線圧着部９５に圧着されることにより端末部に第１接続端子８９が取り付けられた第１端子付電線８１となる。 In the electric wire 81 with a first terminal according to the second embodiment, the first connection terminal 89 is connected to the terminal portion of the electric wire 87. The first connection terminal 89 is formed by sheet metal processing of a metal plate having good conductivity. In the first connection terminal 89, a box-shaped electric contact portion 91, a conductor crimping portion 93, and a covered electric wire crimping portion 95 are connected in this order from the tip side. The first connection terminal 89 becomes a female terminal when the electrical contact portion 91 is formed in a box shape. The male tab terminal of the mating connector (not shown) enters the inside of the electrical contact portion 91. In the second embodiment, the electric wire 87 is a single wire in which a single conductor is covered with an insulating coating. In the electric wire 87, the exposed conductor is crimped to the conductor crimping portion 93 by stripping the insulating coating of the terminal portion. The electric wire 87 becomes an electric wire 81 with a first terminal to which the first connection terminal 89 is attached to the terminal portion by crimping the insulating coating on the base end side of the conductor to the coated electric wire crimping portion 95.

第１接続端子８９は、電気接触部９１と導体圧着部９３との間が、挿入方向後端部９７（図１５の（ｂ）参照）となる。この挿入方向後端部９７には、電気接触部９１の軸回りの挿入姿勢を規制する規制片９９（スタビライザ）が突設される。この規制片９９は、コネクタハウジング７９の第１端子収容室１０１に端子挿入方向で形成される規制溝（図示略）に進入する。これにより、第１接続端子８９は、軸回りの所定の挿入姿勢以外では、第１端子収容室１０１へ挿入できなくなっている。 The first connection terminal 89 has a rear end portion 97 in the insertion direction (see FIG. 15B) between the electrical contact portion 91 and the conductor crimping portion 93. A regulating piece 99 (stabilizer) that regulates the axial insertion posture of the electrical contact portion 91 is projected from the rear end portion 97 in the insertion direction. The regulation piece 99 enters the regulation groove (not shown) formed in the first terminal accommodation chamber 101 of the connector housing 79 in the terminal insertion direction. As a result, the first connection terminal 89 cannot be inserted into the first terminal accommodating chamber 101 except in a predetermined insertion posture around the axis.

コネクタハウジング７９は、絶縁樹脂材により一体成形される。コネクタハウジング７９は、平板状の嵌合部１０３の後端に、直角に垂下する平板状の電線収容箱部１０５が連設されたＬ字形に形成されている。コネクタハウジング７９の両側面には、上下一対のカバー係合凸部１０７が突設されている。カバー係合凸部１０７は、カバー８３をコネクタハウジング７９に係止する。嵌合部１０３には、左右方向に複数の第１端子収容室１０１が並設される。本第２実施形態では、４つの第１端子収容室１０１が形成されている。それぞれの第１端子収容室１０１には、電気接触部９１に係合するランス等の端子係合弾性部（図示略）が設けられている。 The connector housing 79 is integrally molded with an insulating resin material. The connector housing 79 is formed in an L shape in which a flat plate-shaped electric wire accommodating box portion 105 hanging at a right angle is continuously provided at the rear end of the flat plate-shaped fitting portion 103. A pair of upper and lower cover engaging protrusions 107 are projected on both side surfaces of the connector housing 79. The cover engaging protrusion 107 locks the cover 83 to the connector housing 79. A plurality of first terminal accommodating chambers 101 are arranged side by side in the fitting portion 103 in the left-right direction. In the second embodiment, four first terminal accommodating chambers 101 are formed. Each first terminal accommodating chamber 101 is provided with a terminal engaging elastic portion (not shown) such as a lance that engages with the electrical contact portion 91.

第１端子収容室１０１は、嵌合部１０３の先端面が相手端子進入口１０９となって開口している。また、第１端子収容室１０１は、嵌合部１０３の背面が端子挿入口１１１（図１５参照）となって開口している。電線収容箱部１０５の背面には、上下方向に延在する複数の電線収容溝１１３が平行に形成されている。電線収容溝１１３は、第１端子収容室１０１の数と同数（４本）で形成されている。電線収容溝１１３は、上端が端子挿入口１１１に接続される。コネクタハウジング７９は、第１端子収容室１０１に第１接続端子８９が装着された第１端子付電線８１の電線８７が、電線収容箱部１０５に沿って直角に曲げられることにより、それぞれの電線８７が電線収容溝１１３に収容される。 The first terminal accommodating chamber 101 is opened with the tip surface of the fitting portion 103 serving as the mating terminal entrance 109. Further, the first terminal accommodating chamber 101 is opened with the back surface of the fitting portion 103 serving as a terminal insertion port 111 (see FIG. 15). On the back surface of the electric wire accommodating box 105, a plurality of electric wire accommodating grooves 113 extending in the vertical direction are formed in parallel. The number of electric wire accommodating grooves 113 is the same as the number (4) of the first terminal accommodating chambers 101. The upper end of the electric wire accommodating groove 113 is connected to the terminal insertion port 111. In the connector housing 79, the electric wires 87 of the electric wires 81 with the first terminals to which the first connection terminals 89 are mounted in the first terminal accommodating chamber 101 are bent at right angles along the electric wire accommodating box 105, so that the respective electric wires are formed. 87 is accommodated in the electric wire accommodating groove 113.

カバー８３は、絶縁樹脂材により一体成形される。カバー８３は、前面及び下面が開口した箱状に形成されている。カバー８３は、第１端子収容室１０１の端子挿入口１１１及び電線収容溝１１３を覆うようにコネクタハウジング７９に取り付けられる。カバー８３の両側板には、コネクタハウジング７９のカバー係合凸部１０７に係止されるハウジング係止穴１１５と不図示の係止部が形成されている。カバー８３の上面板１１７には、左右方向に４つのＵ字状の切欠１１９が形成されている。この切欠１１９には、第１端子付電線８１の電線８７が挿入される。カバー８３の前面には、切欠１１９の下方に、４つの電線保持部１２１が形成されている。それぞれの電線保持部１２１は、一対の逆Ｌ字状の保持脚１２３（図１６参照）からなる。電線保持部１２１は、一対の保持脚１２３を弾性変形させて拡開させながら電線８７を挿入することで、電線８７を挟んで保持する。また、電線保持部１２１は、保持した電線８７が電線８７の延在方向に動けるように挟む。 The cover 83 is integrally molded with an insulating resin material. The cover 83 is formed in a box shape with the front surface and the lower surface open. The cover 83 is attached to the connector housing 79 so as to cover the terminal insertion port 111 and the electric wire accommodating groove 113 of the first terminal accommodating chamber 101. A housing locking hole 115 and a locking portion (not shown) that are locked to the cover engaging convex portion 107 of the connector housing 79 are formed on both side plates of the cover 83. The upper surface plate 117 of the cover 83 is formed with four U-shaped notches 119 in the left-right direction. The electric wire 87 of the electric wire 81 with the first terminal is inserted into the notch 119. On the front surface of the cover 83, four electric wire holding portions 121 are formed below the notch 119. Each wire holding portion 121 is composed of a pair of inverted L-shaped holding legs 123 (see FIG. 16). The electric wire holding portion 121 sandwiches and holds the electric wire 87 by inserting the electric wire 87 while elastically deforming and expanding the pair of holding legs 123. Further, the electric wire holding portion 121 sandwiches the held electric wire 87 so that the electric wire 87 can move in the extending direction of the electric wire 87.

カバー８３は、切欠１１９と電線保持部１２１との間の前面に、左右方向に長い突起挿通穴１２５が穿設されている。突起挿通穴１２５には、リテーナ８５に設けられた係止突起１２７が挿通される。 The cover 83 is provided with a protrusion insertion hole 125 long in the left-right direction on the front surface between the notch 119 and the electric wire holding portion 121. A locking protrusion 127 provided on the retainer 85 is inserted into the protrusion insertion hole 125.

図１４は図１３に示したカバー８３とリテーナ８５の分解斜視図である。
カバー８３の背面には、リテーナ嵌合凹部１２９が形成されている。リテーナ嵌合凹部１２９の上部には、上述の突起挿通穴１２５が開口する。リテーナ嵌合凹部１２９の左右には、上下に延在するリテーナ側板挿入溝１３１が形成されている。 FIG. 14 is an exploded perspective view of the cover 83 and the retainer 85 shown in FIG.
A retainer fitting recess 129 is formed on the back surface of the cover 83. The above-mentioned protrusion insertion hole 125 opens in the upper part of the retainer fitting recess 129. Retainer side plate insertion grooves 131 extending vertically are formed on the left and right sides of the retainer fitting recess 129.

リテーナ８５は、絶縁樹脂材により一体成形される。リテーナ８５は、左右方向に長い矩形状の基板部１３３の両側に、前方に向かって突出する一対の平行なリテーナ側板１３５が形成されている。リテーナ８５は、基板部１３３がカバー８３のリテーナ嵌合凹部１２９に嵌合し、一対のリテーナ側板１３５がカバー８３のリテーナ側板挿入溝１３１に挿入される。基板部１３３の上部前面には、前方に向かって突出する複数の係止突起１２７が左右方向に並設されている。本第２実施形態において、係止突起１２７は、４本となる。係止突起１２７は、リテーナ８５のリテーナ側板１３５がカバー８３のリテーナ側板挿入溝１３１に装着されることで、突起挿通穴１２５を貫通してカバー８３の前面から突出する。カバー８３の前面から突出した係止突起１２７は、カバー８３の電線保持部１２１に保持される第１端子付電線８１のそれぞれの電線８７を所定間隔に保持することができる。カバー８３は、リテーナ８５を装着した状態で、サブアッセンブリ品となる。 The retainer 85 is integrally molded with an insulating resin material. The retainer 85 is formed with a pair of parallel retainer side plates 135 projecting forward on both sides of a rectangular substrate portion 133 that is long in the left-right direction. In the retainer 85, the substrate portion 133 is fitted into the retainer fitting recess 129 of the cover 83, and the pair of retainer side plates 135 are inserted into the retainer side plate insertion groove 131 of the cover 83. A plurality of locking projections 127 projecting forward are arranged side by side in the left-right direction on the upper front surface of the substrate portion 133. In the second embodiment, the number of locking projections 127 is four. The locking projection 127 penetrates the projection insertion hole 125 and projects from the front surface of the cover 83 when the retainer side plate 135 of the retainer 85 is mounted in the retainer side plate insertion groove 131 of the cover 83. The locking projection 127 protruding from the front surface of the cover 83 can hold the respective electric wires 87 of the electric wire 81 with the first terminal held by the electric wire holding portion 121 of the cover 83 at predetermined intervals. The cover 83 is a sub-assembled product with the retainer 85 attached.

また、それぞれのリテーナ側板１３５の上端面には、係止爪１３７（図１４参照）が突設されている。この係止爪１３７は、カバー８３のリテーナ側板挿入溝１３１に形成される仮係止部（図示略）と本係止部（図示略）とに段階的に係止される。リテーナ８５は、係止爪１３７が仮係止部に係止されることで、基板部１３３がリテーナ嵌合凹部１２９に嵌る直前のプリセット位置に突出して保持される。リテーナ８５は、係止爪１３７が本係止部に係止されることで、基板部１３３がリテーナ嵌合凹部１２９に嵌着した本係止状態とされる。 Further, a locking claw 137 (see FIG. 14) is projected from the upper end surface of each retainer side plate 135. The locking claw 137 is stepwise locked to a temporary locking portion (not shown) and a main locking portion (not shown) formed in the retainer side plate insertion groove 131 of the cover 83. The retainer 85 is held in a preset position immediately before the substrate portion 133 is fitted into the retainer fitting recess 129 by locking the locking claw 137 to the temporary locking portion. The retainer 85 is brought into the main locked state in which the substrate portion 133 is fitted in the retainer fitting recess 129 by locking the locking claw 137 to the main locking portion.

ここで、リテーナ８５は、本係止状態で、係止突起１２７の先端が、第１端子収容室１０１の所定位置に進入することとなる。係止突起１２７は、第１端子収容室１０１の所定位置に進入することで、第１端子収容室１０１に装着されている第１接続端子８９の規制片９９に後方より当接する。すなわち、第１接続端子８９は、規制片９９に係止突起１２７が当接することにより、第１端子収容室１０１からの離脱が二重に規制される。 Here, in the retainer 85, the tip of the locking projection 127 enters a predetermined position of the first terminal accommodating chamber 101 in the locked state. By entering the predetermined position of the first terminal accommodating chamber 101, the locking projection 127 abuts from the rear on the regulation piece 99 of the first connection terminal 89 mounted in the first terminal accommodating chamber 101. That is, the first connection terminal 89 is doubly restricted from being separated from the first terminal accommodating chamber 101 by the locking projection 127 coming into contact with the regulation piece 99.

なお、本第２実施形態では、係止突起１２７が、規制片９９に当接する例を説明したが、係止突起１２７は、電気接触部９１の挿入方向後端部９７に直接当接することにより第１接続端子８９を二重係止する構成であってもよい。 In the second embodiment, the example in which the locking projection 127 abuts on the regulation piece 99 has been described, but the locking projection 127 directly abuts on the rear end portion 97 of the electrical contact portion 91 in the insertion direction. The first connection terminal 89 may be double-locked.

次に、上記構成を有する本第２実施形態に係るコネクタの組立方法を説明する。
図１５の（ａ）は第１端子付電線８１がセットされたカバー８３を表す手順説明図、図１５の（ｂ）はカバー８３に保持された第１端子付電線８１の第１接続端子８９が端子挿入口１１１に挿入される直前の状態を表す手順説明図である。
本第２実施形態のコネクタの組立方法では、図１３に示すように、電線８７の端末部に、先ず、第１接続端子８９が圧着される。電線８７は、絶縁被覆が除去されて導体に第１接続端子８９の導体圧着部９３が圧着され、絶縁被覆が被覆電線圧着部９５に圧着される。これにより、電線８７は、第１端子付電線８１となる。 Next, a method of assembling the connector according to the second embodiment having the above configuration will be described.
FIG. 15A is a procedure explanatory view showing a cover 83 in which the electric wire 81 with the first terminal is set, and FIG. 15B is the first connection terminal 89 of the electric wire 81 with the first terminal held by the cover 83. Is a procedure explanatory view showing a state immediately before being inserted into the terminal insertion port 111.
In the connector assembly method of the second embodiment, as shown in FIG. 13, the first connection terminal 89 is first crimped to the terminal portion of the electric wire 87. In the electric wire 87, the insulating coating is removed, the conductor crimping portion 93 of the first connection terminal 89 is crimped to the conductor, and the insulating coating is crimped to the coated electric wire crimping portion 95. As a result, the electric wire 87 becomes the electric wire 81 with the first terminal.

カバー８３には、リテーナ８５が、仮係止位置に装着されている。リテーナ８５が装着されたカバー８３のサブアッセンブリ品には、それぞれの電線保持部１２１に第１端子付電線８１がセットされる。第１端子付電線８１は、電線８７が電線保持部１２１に挟まれ、その先端側が切欠１１９に保持される。また、第１端子付電線８１は、電線保持部１２１と切欠１１９との間の電線８７が、リテーナ８５の係止突起１２７により離間して所定間隔に位置決めされる。すなわち、複数の第１端子付電線８１は、電線保持部１２１に保持されながら、カバー８３に仮係止位置でプリセットされているリテーナ８５の係止突起１２７によって所定間隔に保持された状態となる。 A retainer 85 is attached to the cover 83 at a temporary locking position. In the sub-assembled product of the cover 83 to which the retainer 85 is mounted, the electric wire 81 with the first terminal is set in each electric wire holding portion 121. In the electric wire 81 with the first terminal, the electric wire 87 is sandwiched between the electric wire holding portions 121, and the tip end side thereof is held by the notch 119. Further, in the electric wire 81 with the first terminal, the electric wire 87 between the electric wire holding portion 121 and the notch 119 is separated by the locking projection 127 of the retainer 85 and is positioned at a predetermined interval. That is, the plurality of electric wires 81 with the first terminal are held at predetermined intervals by the locking projections 127 of the retainer 85 preset in the cover 83 at the temporary locking position while being held by the electric wire holding portion 121. ..

図１６はカバー８３に設けられる電線保持部１２１の要部拡大図である。
第１端子付電線８１は、電線保持部１２１に挟まれた状態で、電線保持部１２１からの離脱が規制される。電線保持部１２１は、電線８７の離脱を規制する一方、電線８７の長手方向の移動は可能としている。従って、第１端子付電線８１は、図１５（ａ）の上下方向に沿って、電線保持部１２１に対する位置調整が可能となる。 FIG. 16 is an enlarged view of a main part of the electric wire holding portion 121 provided on the cover 83.
The wire 81 with the first terminal is restricted from being separated from the wire holding portion 121 while being sandwiched between the wire holding portions 121. The electric wire holding portion 121 regulates the detachment of the electric wire 87, while allowing the electric wire 87 to move in the longitudinal direction. Therefore, the position of the electric wire 81 with the first terminal can be adjusted with respect to the electric wire holding portion 121 along the vertical direction of FIG. 15A.

複数の第１端子付電線８１は、図１５（ｂ）に示すように、カバー８３に保持された状態で、それぞれの第１接続端子８９が、第１端子収容室１０１に順次挿入される。 As shown in FIG. 15B, the plurality of first terminal-attached electric wires 81 are held by the cover 83, and the first connection terminals 89 are sequentially inserted into the first terminal accommodating chamber 101.

図１７の（ａ）はリテーナ８５が仮係止位置のカバー８３及びコネクタハウジング７９を表す手順説明図、図１７の（ｂ）はリテーナ８５が本係止位置となったカバー８３及びコネクタハウジング７９を表す手順説明図である。
カバー８３は、全ての第１接続端子８９が第１端子収容室１０１に装着された後、電線保持部１２１に対して電線８７の位置が調整されて、図１７（ａ）に示すように、コネクタハウジング７９に装着される。すなわち、コネクタ２００では、電線保持部１２１に対する第１端子付電線８１の長手方向に沿った保持位置を調整しながら、第１端子収容室１０１に収容された第１接続端子８９を抜け止めすると共に、電線収容箱部１０５に沿って直角に曲げられて電線収容溝１１３に収容された電線８７を覆うため、カバー８３がコネクタハウジング７９に取り付けられる。 FIG. 17 (a) is a procedure explanatory view showing the cover 83 and the connector housing 79 in which the retainer 85 is temporarily locked, and FIG. 17 (b) is the cover 83 and the connector housing 79 in which the retainer 85 is in the main locked position. It is a procedure explanatory drawing which shows.
In the cover 83, after all the first connection terminals 89 are mounted in the first terminal accommodating chamber 101, the position of the electric wire 87 is adjusted with respect to the electric wire holding portion 121, and as shown in FIG. It is attached to the connector housing 79. That is, in the connector 200, while adjusting the holding position of the electric wire 81 with the first terminal with respect to the electric wire holding portion 121 along the longitudinal direction, the first connection terminal 89 housed in the first terminal accommodating chamber 101 is prevented from coming off. The cover 83 is attached to the connector housing 79 in order to cover the electric wire 87 accommodated in the electric wire accommodating groove 113 by being bent at a right angle along the electric wire accommodating box portion 105.

コネクタ２００は、図１７に示すように、カバー係合凸部１０７にハウジング係止穴１１５と不図示の係止部が係止されて、カバー８３がコネクタハウジング７９にセットされる。この際、リテーナ８５は、未だ仮係止位置とされ、基板部１３３がリテーナ嵌合凹部１２９から後方へ突出した状態となっている。コネクタ２００は、この状態で、リテーナ８５がリテーナ嵌合凹部１２９に押し込まれる。 In the connector 200, as shown in FIG. 17, a housing locking hole 115 and a locking portion (not shown) are locked to the cover engaging convex portion 107, and the cover 83 is set in the connector housing 79. At this time, the retainer 85 is still in the temporary locking position, and the substrate portion 133 is in a state of protruding rearward from the retainer fitting recess 129. In this state, the retainer 85 of the connector 200 is pushed into the retainer fitting recess 129.

図１８に示すように、コネクタ２００は、コネクタハウジング７９に取り付けられたカバー８３に、プリセットされているリテーナ８５が本係止位置に移動されることにより、第１端子収容室１０１に収容された第１接続端子８９の挿入方向後端部９７（本実施形態では規制片９９）がリテーナ８５の係止突起１２７に対向配置される。これにより、第１接続端子８９は、図示しないランスと係止突起１２７とにより二重に抜け止めされる。
コネクタ２００は、このリテーナ８５の本係止状態で、組み立てが完了する。 As shown in FIG. 18, the connector 200 is housed in the first terminal storage chamber 101 by moving the preset retainer 85 to the main locking position on the cover 83 attached to the connector housing 79. The rear end portion 97 of the first connection terminal 89 in the insertion direction (regulatory piece 99 in this embodiment) is arranged to face the locking projection 127 of the retainer 85. As a result, the first connection terminal 89 is double-locked by a lance and a locking projection 127 (not shown).
Assembly of the connector 200 is completed in the locked state of the retainer 85.

次に、上記したコネクタの組立方法の作用を説明する。
本第２実施形態に係るコネクタの組立方法では、複数の第１端子付電線８１が、カバー８３の電線保持部１２１に保持される。つまり、複数の第１端子付電線８１が、カバー８３にプリセットされる。それぞれの第１端子付電線８１は、第１接続端子８９が電線８７の端末部に圧着された後、圧着順にカバー８３へ保持させることができる。そのため、複数の第１端子付電線８１はフリーとならず、端子同士の接触や電線同士の絡みが生じない。 Next, the operation of the above-mentioned connector assembly method will be described.
In the connector assembly method according to the second embodiment, a plurality of electric wires 81 with first terminals are held by the electric wire holding portion 121 of the cover 83. That is, a plurality of electric wires 81 with first terminals are preset in the cover 83. Each electric wire 81 with a first terminal can be held by the cover 83 in the order of crimping after the first connection terminal 89 is crimped to the terminal portion of the electric wire 87. Therefore, the plurality of wires 81 with the first terminal are not free, and contact between the terminals and entanglement between the wires do not occur.

また、本第２実施形態のコネクタの組立方法では、ストレート形状の第１接続端子８９を設けた第１端子付電線８１において、電線８７を曲げることにより、Ｌ字タイプのコネクタ２００と、一般的な水平タイプのコネクタとで、第１端子付電線８１を共用できる。
また、電線８７を９０度曲げする際に、カバー８３（特に前方に突出するリテーナ８５の係止突起１２７）で位置規制することにより、カバー８３とコネクタハウジング７９を組み付ける際の電線８７の挟み込みを防止できる。 Further, in the method of assembling the connector of the second embodiment, in the electric wire 81 with the first terminal provided with the straight-shaped first connection terminal 89, the electric wire 87 is bent to form an L-shaped connector 200. The electric wire 81 with the first terminal can be shared with the horizontal type connector.
Further, when the electric wire 87 is bent 90 degrees, the position is regulated by the cover 83 (particularly, the locking projection 127 of the retainer 85 protruding forward), so that the electric wire 87 is sandwiched when the cover 83 and the connector housing 79 are assembled. Can be prevented.

また、本第２実施形態のコネクタの組立方法では、第１端子付電線８１が、カバー８３に保持される。カバー８３には、リテーナ８５が装着される。リテーナ８５は、カバー８３に対し、仮係止位置とコネクタハウジング７９に近接する位置の本係止位置とに、選択的に配置が可能となっている。また、リテーナ８５には、複数の係止突起１２７が並設される。係止突起１２７は、カバー８３を貫通し、電線保持部１２１に保持されている複数の第１端子付電線８１を、所定間隔に位置決め可能とする。これにより、コネクタ２００は、複数の第１端子付電線８１が、カバー８３の電線保持部１２１に保持される。つまり、カバー８３には、複数の第１端子付電線８１が、プリセットされる。それぞれの第１端子付電線８１は、第１接続端子８９が圧着された後、圧着順にカバー８３へ保持される。そのため、複数の第１端子付電線８１はフリーとならず、端子同士の接触や電線同士の絡みが生じない。 Further, in the connector assembly method of the second embodiment, the electric wire 81 with the first terminal is held by the cover 83. A retainer 85 is attached to the cover 83. The retainer 85 can be selectively arranged at a temporary locking position and a main locking position close to the connector housing 79 with respect to the cover 83. Further, a plurality of locking projections 127 are arranged side by side on the retainer 85. The locking projection 127 penetrates the cover 83 and enables the plurality of electric wires 81 with first terminals held by the electric wire holding portion 121 to be positioned at predetermined intervals. As a result, in the connector 200, a plurality of electric wires 81 with first terminals are held by the electric wire holding portion 121 of the cover 83. That is, a plurality of electric wires 81 with first terminals are preset on the cover 83. Each electric wire 81 with a first terminal is held on the cover 83 in the order of crimping after the first connection terminal 89 is crimped. Therefore, the plurality of wires 81 with the first terminal are not free, and contact between the terminals and entanglement between the wires do not occur.

カバー８３は、全ての第１端子付電線８１を保持した状態で、コネクタハウジング７９に取り付けられる。この際、複数の第１端子付電線８１は、カバー８３の電線保持部１２１とカバー８３に装着されたリテーナ８５の係止突起１２７とによって既に第１接続端子８９が所定の順に並べられている。このため、第１端子付電線８１は、例えば左側から順に第１接続端子８９をコネクタハウジング７９の第１端子収容室１０１へ挿入していけばよく、挿入対象の第１端子収容室１０１を確認する手間が省け、挿入作業を良好に行うことができる。 The cover 83 is attached to the connector housing 79 while holding all the electric wires 81 with the first terminals. At this time, in the plurality of electric wires 81 with first terminals, the first connection terminals 89 are already arranged in a predetermined order by the electric wire holding portion 121 of the cover 83 and the locking projection 127 of the retainer 85 mounted on the cover 83. .. Therefore, for the electric wire 81 with the first terminal, for example, the first connection terminal 89 may be inserted into the first terminal accommodating chamber 101 of the connector housing 79 in order from the left side, and the first terminal accommodating chamber 101 to be inserted is confirmed. You can save the trouble of doing it and perform the insertion work well.

リテーナ８５は、カバー８３がコネクタハウジング７９に取り付けられた後、本係止位置に移動される。リテーナ８５は、本係止位置に移動されると、係止突起１２７が第１接続端子８９の挿入方向後端部９７を係止する。これにより、リテーナ８５は、第１接続端子８９が第１端子収容室１０１から抜け出すのを阻止することができる。 The retainer 85 is moved to the main locking position after the cover 83 is attached to the connector housing 79. When the retainer 85 is moved to the main locking position, the locking projection 127 locks the rear end portion 97 of the first connection terminal 89 in the insertion direction. As a result, the retainer 85 can prevent the first connection terminal 89 from coming out of the first terminal accommodating chamber 101.

従って、上述した第１及び第２実施形態に係るコネクタの組立方法によれば、電線２１（８７）の絡みや端子２３，２５（８９）の傷付きを防止して、端子挿入作業を良好に行うことができる。 Therefore, according to the connector assembly method according to the first and second embodiments described above, it is possible to prevent the electric wire 21 (87) from being entangled and the terminals 23 and 25 (89) from being damaged, so that the terminal insertion work can be performed satisfactorily. It can be carried out.
