次に、本実施形態に係る電線１０の端末構造の組み付け方法等を説明する。
まず、両かしめ片２４を電線１０の芯線１１にかしめ付け、電線１０の端部に端子金具２０を接続する。また、電線１０の被覆１２にリング部材３０をかしめ付ける。このとき、リング部材３０の前方にブラケット４０を位置させる。続いて、ブラケット４０を後退させる。すると、リング部材３０に係止爪５４が乗り上げられ、弾性片５３が外側に撓み変形される。ブラケット４０が正規の装着位置に到達すると、弾性片５３が弾性復帰し、係止爪５４がリング部材３０の第２段差３６に当接可能に配置されて、ブラケット４０の前進が規制される。また、係止縁５６がリング部材３０の第１段差３５に当接可能に配置されて、ブラケット４０の後退が規制される。これにより、ブラケット４０が電線１０に対して前後方向に位置決めされた状態で保持される。さらに、弾性片５３の内面が対向辺部３２の外面に略面接触状態で当接して、リング部材３０ひいては電線１０に対するブラケット４０の軸回りの回転が規制される。 Next, a method for assembling the terminal structure of the electric wire 10 according to the present embodiment will be described.
First, the both caulking pieces 24 are caulked to the core wire 11 of the electric wire 10, and the terminal fitting 20 is connected to the end of the electric wire 10. Further, the ring member 30 is caulked to the covering 12 of the electric wire 10. At this time, the bracket 40 is positioned in front of the ring member 30. Subsequently, the bracket 40 is retracted. Then, the locking claw 54 rides on the ring member 30, and the elastic piece 53 is bent outward and deformed. When the bracket 40 reaches the proper mounting position, the elastic piece 53 is elastically restored, and the locking claw 54 is disposed so as to be able to contact the second step 36 of the ring member 30, thereby restricting the forward movement of the bracket 40. Further, the locking edge 56 is disposed so as to be able to contact the first step 35 of the ring member 30, and the backward movement of the bracket 40 is restricted. Thereby, the bracket 40 is held in a state of being positioned in the front-rear direction with respect to the electric wire 10. Furthermore, the inner surface of the elastic piece 53 is brought into contact with the outer surface of the opposed side portion 32 in a substantially surface contact state, and the rotation of the bracket member 40 and the bracket 40 relative to the electric wire 10 is restricted.

そして、適宜タイミングでブラケット４０のゴム栓収容空間４７に後方からゴム栓８０を挿入し、続いて、ブラケット４０の後端部に後方からキャップ９０を取り付ける。また、ブラケット４０の保持溝４６にシールリング７０を嵌着させる。   Then, the rubber plug 80 is inserted into the rubber plug housing space 47 of the bracket 40 from the rear at an appropriate timing, and then the cap 90 is attached to the rear end portion of the bracket 40 from the rear. Further, the seal ring 70 is fitted into the holding groove 46 of the bracket 40.

次いで、シールドケース１０１の内部に、取付孔１０２を介して、後方から端子金具２０を挿入し、かつシールドケース１０１の側壁外面に取付部４２を当て付ける。その状態で、ねじ部材４００を挿通孔４３から雌ねじ孔１０３にねじ込み、ブラケット４０をシールドケース１０１の側壁に取り付ける。また、ボルト３００をボルト孔２３から導電部２００にねじ込み、導電部２００に端子金具２０を接続させる。   Next, the terminal fitting 20 is inserted into the inside of the shield case 101 from the rear via the attachment hole 102, and the attachment portion 42 is applied to the outer surface of the side wall of the shield case 101. In this state, the screw member 400 is screwed into the female screw hole 103 from the insertion hole 43, and the bracket 40 is attached to the side wall of the shield case 101. Further, the bolt 300 is screwed into the conductive portion 200 from the bolt hole 23 and the terminal fitting 20 is connected to the conductive portion 200.

以上説明したように、本実施形態によれば、リング部材３０が電線１０に締結され、リング部材３０の第１、第２段差３５、３６に係止縁５６及び弾性片５３の係止爪５４がそれぞれ当接することにより、ブラケット４０が電線１０に対して軸方向に変位するのが規制されるため、機器１００への取り付け前に、電線１０に対するブラケット４０の位置変動が抑えられ、モールド構造が廃止されても、取り扱い性の良好な、電線１０の端末構造が提供される。   As described above, according to the present embodiment, the ring member 30 is fastened to the electric wire 10, and the locking edge 56 and the locking claw 54 of the elastic piece 53 are connected to the first and second steps 35 and 36 of the ring member 30. , The bracket 40 is restricted from being displaced in the axial direction with respect to the electric wire 10, so that the position variation of the bracket 40 with respect to the electric wire 10 can be suppressed before being attached to the device 100, and the mold structure can be reduced. Even if it is abolished, the terminal structure of the electric wire 10 with good handleability is provided.

また、電線１０に沿ってブラケット４０をスライドさせることにより、弾性片５３の係止爪５４が第２段差３６を弾性的に係止して、ブラケット４０がリング部材３０に保持されるから、組み付けの作業性が良好となる。   Further, by sliding the bracket 40 along the electric wire 10, the locking claw 54 of the elastic piece 53 elastically locks the second step 36, and the bracket 40 is held by the ring member 30. The workability is improved.

また、リング部材３０の対向辺部３２の外面が弾性片５３の内面と当接することにより、電線１０に対するブラケット４０の軸回りの回転が規制されるため、ブラケット４０の取り扱い性がより良好となる。   Further, since the outer surface of the opposite side portion 32 of the ring member 30 is in contact with the inner surface of the elastic piece 53, the rotation of the bracket 40 around the axis with respect to the electric wire 10 is restricted, so that the handleability of the bracket 40 becomes better. .

さらに、ゴム栓８０の内周面が電線１０の外周面に密着するとともに、ゴム栓８０の外周面が電線挿通孔４５の内周面に密着するため、ブラケット４０内のシールがとられる。したがって、モールド構造をとらずとも、所定の防水性が確保される。   Furthermore, since the inner peripheral surface of the rubber plug 80 is in close contact with the outer peripheral surface of the electric wire 10 and the outer peripheral surface of the rubber plug 80 is in close contact with the inner peripheral surface of the electric wire insertion hole 45, the seal in the bracket 40 is taken. Therefore, even if it does not take a mold structure, predetermined waterproofness is ensured.
