When projecting for a predetermined length, as shown in FIG. 11, a plurality of protrusions 62, each having a guide surface 62 a for guiding the tip portions 35 e, 36 e of the terminals 35, 36 in the concave terminal holder storage portion 25 of the cover 20, The terminal mounting jig 60 made of synthetic resin having 62 is accommodated and positioned on the insertion port 24a 'side of each terminal through hole 24a, and between the projections 62, 62 of the terminal mounting jig 60 Let's face it.

次に、ターミナル取付用治具60の各突起62,62のガイド面62aを介して各ターミナル貫通孔24aの差込口24a′に各ターミナル35,36の先端部35e,36eを差し込む。そして、カバー20の凹状のターミナルホルダ収納部25からターミナル取付用治具60を取り外した後で、各ターミナル貫通孔24aに各ターミナル35,36の中途部36b,36bを貫通させてコネクタ部23内に該各ターミナル35,36を所定長突出させる。   Next, the tip portions 35e and 36e of the terminals 35 and 36 are inserted into the insertion ports 24a 'of the terminal through holes 24a through the guide surfaces 62a of the protrusions 62 and 62 of the terminal mounting jig 60, respectively. Then, after the terminal mounting jig 60 is removed from the concave terminal holder storage portion 25 of the cover 20, the middle portions 36 b and 36 b of the terminals 35 and 36 are passed through the terminal through holes 24 a so that the inside of the connector portion 23. The terminals 35 and 36 are projected for a predetermined length.

次に、図7に示すように、カバー20の凹部ターミナルホルダ収納部25に合成樹脂製のターミナルホルダ40を収納して、各ターミナル35,36の中途部35b,36bを該ターミナルホルダ40の複数の突起45,46,47でそれぞれ保持する。   Next, as shown in FIG. 7, the terminal holder 40 made of synthetic resin is stored in the recessed terminal holder storage portion 25 of the cover 20, and the middle portions 35 b and 36 b of the terminals 35 and 36 are connected to the terminal holder 40. Are held by the projections 45, 46 and 47, respectively.

このように、カバー20のコネクタ部23の底壁24の複数のターミナル貫通孔24aの差込口24a′に複数のターミナル35,36の先端部35e,36eを差し込んで該コネクタ部23内に該複数のターミナル35,36を所定長突出させて組み付ける際に、コネクタ部23の底壁24の複数のターミナル貫通孔24aの差込口24a′側に複数のターミナル35,36の先端部35e,36eを案内するガイド面を形成することができない場合において、カバー20の凹状のターミナルホルダ収納部25に収納されたターミナル取付用治具60の複数の突起62のガイド面62aを介して複数のターミナル貫通孔24aの差込口24a′に複数のターミナル35,36の先端部35e,36eをそれぞれ差し込んで、各ターミナル貫通孔24aに各ターミナル35,36の中途部35b,36bを貫通させてコネクタ部23内に該各ターミナル35,36を所定長突出させることができる。このため、カバー20のコネクタ部23の底壁24の複数のターミナル貫通孔24aに複数のターミナル35,36を簡単かつ確実に組み付けることができ、その作業性を向上させることができる。   In this way, the tip portions 35e, 36e of the plurality of terminals 35, 36 are inserted into the insertion ports 24a 'of the plurality of terminal through holes 24a of the bottom wall 24 of the connector portion 23 of the cover 20, and the connector portion 23 is inserted into the connector portion 23. When assembling the plurality of terminals 35 and 36 so as to protrude by a predetermined length, the front end portions 35e and 36e of the plurality of terminals 35 and 36 are provided on the side of the insertion port 24a ′ of the plurality of terminal through holes 24a on the bottom wall 24 of the connector portion 23. When the guide surface for guiding the terminal cannot be formed, the plurality of terminals penetrate through the guide surfaces 62a of the plurality of protrusions 62 of the terminal mounting jig 60 housed in the concave terminal holder housing portion 25 of the cover 20. The tip portions 35e and 36e of the plurality of terminals 35 and 36 are respectively inserted into the insertion ports 24a 'of the holes 24a so that each terminal is inserted. Intermediate portion 35b of each terminal 35, 36 in the hole 24a, the respective terminals 35, 36 in the connector portion 23 is passed through a 36b can be predetermined length protrudes. Therefore, the plurality of terminals 35 and 36 can be easily and reliably assembled to the plurality of terminal through holes 24a of the bottom wall 24 of the connector portion 23 of the cover 20, and the workability thereof can be improved.

また、複数のターミナル35,36の中途部35b,36bを保持するターミナルホルダ40が収納されるカバー20の凹状のターミナルホルダ収納部25にターミナル取付用治具60を着脱自在に収納するようにしたので、カバー20のレイアウト性を向上させることができる。   Further, the terminal mounting jig 60 is detachably stored in the concave terminal holder storage portion 25 of the cover 20 in which the terminal holder 40 holding the middle portions 35b and 36b of the terminals 35 and 36 is stored. As a result, the layout of the cover 20 can be improved.

さらに、カバー20のコネクタ部23に複数のターミナル35,36を組み付けた後は、ターミナルホルダ40の各突起45,46,47で複数のターミナル35,36の中途部35b,36bをそれぞれ保持するようにしたので、各ターミナル35,36の中途部35b,36bに形成された凸部35c,36cの切欠き35d,36d内に、ターミナルホルダ40の各突起45,46,47が嵌め込まれ、カバー20のコネクタ部23内への相手コネクタ50の着脱時に各ターミナル35,36に加わる負荷は、カバー20の凹状のターミナルホルダ収納部25に収納されたターミナルホルダ40が受けるため、ブラシホルダ30のターミナル取付部としてのターミナル固定孔部31c及び溶着部31dに負荷が加わることがなく、該ターミナル取付部31c,31dの破損等を確実に防止することができる。特に、複数のターミナル35,36の略中央である中途部35b,36bをターミナルホルダ40の複数の突起45,46,47によりそれぞれ保持するようにしたので、長尺の複数のターミナル35,36の変形やガタ付きを確実に防止することができる。   Further, after the plurality of terminals 35 and 36 are assembled to the connector portion 23 of the cover 20, the middle portions 35 b and 36 b of the plurality of terminals 35 and 36 are respectively held by the projections 45, 46 and 47 of the terminal holder 40. Therefore, the protrusions 45, 46, 47 of the terminal holder 40 are fitted into the notches 35d, 36d of the convex portions 35c, 36c formed in the middle portions 35b, 36b of the terminals 35, 36, and the cover 20 Since the terminal holder 40 accommodated in the concave terminal holder accommodating portion 25 of the cover 20 receives a load applied to the terminals 35 and 36 when the mating connector 50 is attached to and detached from the connector portion 23 of the connector 23, the terminal attachment of the brush holder 30 is performed. No load is applied to the terminal fixing hole 31c and the welding part 31d as the parts, and Terminal attachment portions 31c, 31d of damage can be reliably prevented. In particular, the middle portions 35b and 36b, which are substantially the center of the plurality of terminals 35 and 36, are held by the plurality of protrusions 45, 46 and 47 of the terminal holder 40, respectively. Deformation and backlash can be reliably prevented.

さらに、カバー20の凹状のターミナルホルダ収納部25に各ターミナル35,36の先端部35e,36eを案内するガイド面62aを形成した複数の突起62,62を有した合成樹脂製のターミナル取付用治具60を着脱自在にしたので、各ターミナル貫通孔24aの差込口24a′側に例えばガイド板等をインサート成形して複数のターミナルを組み付ける場合に比べて、低コストで複数のターミナルを組み付けることができる。   Furthermore, the terminal mounting jig made of a synthetic resin having a plurality of projections 62 and 62 in which a guide surface 62a for guiding the tip portions 35e and 36e of the terminals 35 and 36 is formed in the concave terminal holder storage portion 25 of the cover 20. Since the tool 60 is made detachable, it is possible to assemble a plurality of terminals at a lower cost compared to a case where a plurality of terminals are assembled by insert molding of a guide plate or the like on the insertion port 24a 'side of each terminal through hole 24a. Can do.
