さらに、重合板４８の下面４８Ａ（内側面）が上壁１８の左接点４０右側の配置面１８Ａに比し筒体１６内周側に配置されると共に、重合板４８の上面４８Ｂ（外側面）が上壁１８の配置面１８Ａと同一面上に配置されている。このため、筒体１６の上部の肉厚Ｗを効果的に小さくでき、筒体１６を効果的に小型化できて、メスターミナル１０及びメスコネクタを効果的に小型化できる。   Furthermore, the lower surface 48A (inner surface) of the overlapping plate 48 is disposed on the inner peripheral side of the cylindrical body 16 as compared with the disposing surface 18A on the right side of the left contact 40 of the upper wall 18, and the upper surface 48B (outer surface) of the overlapping plate 48. Are arranged on the same plane as the arrangement surface 18 </ b> A of the upper wall 18. For this reason, the wall thickness W of the upper part of the cylinder 16 can be made small effectively, the cylinder 16 can be reduced in size effectively, and the female terminal 10 and the female connector can be reduced in size effectively.

また、左接点４０が条材５２の挿入穴４４形成部位に設けられている。このため、条材５２への挿入穴４４の形成によって左接点４０を設けることができ、左接点４０を容易に設けることができる。しかも、左接点４０に重合板４８が重合されるため、筒体１６内に挿入されたオスターミナル２６の押圧力に対する筒体１６の強度を大きくできる。   Further, the left contact 40 is provided in the insertion hole 44 forming portion of the strip 52. For this reason, the left contact 40 can be provided by forming the insertion hole 44 in the strip 52, and the left contact 40 can be easily provided. Moreover, since the overlapping plate 48 is superposed on the left contact 40, the strength of the cylindrical body 16 against the pressing force of the male terminal 26 inserted into the cylindrical body 16 can be increased.

さらに、上壁１８の内薄肉部４２と重合板４８とが重合されることで、左接点４０の係止部４６と重合板４８の係合部５０と係合可能にされている。このため、筒体１６の成形状態（組立状態）を効果的に維持できる。   Further, the inner thin portion 42 of the upper wall 18 and the overlapping plate 48 are superposed so that the engaging portion 46 of the left contact 40 and the engaging portion 50 of the overlapping plate 48 can be engaged. For this reason, the molding state (assembly state) of the cylindrical body 16 can be effectively maintained.

また、金型によるプレス加工により条材５２を形成する際に、条材５２の内薄肉部４２及び重合板４８の部分を潰し加工する。このため、内薄肉部４２及び重合板４８を条材５２の他の部分に比し容易に薄肉にできる。   Further, when the strip material 52 is formed by press working with a mold, the inner thin portion 42 and the overlapping plate 48 of the strip material 52 are crushed. For this reason, the inner thin part 42 and the superposition | polymerization board 48 can be made thin easily compared with the other part of the strip 52. FIG.

なお、本実施の形態では、本発明をメスターミナル１０に設けられた筒体１６（箱体）に適用した構成としたが、本発明をオスターミナル２６（ターミナル）に設けられた筒体１６（箱体）に適用した構成としてもよい。   In the present embodiment, the present invention is applied to the cylinder 16 (box) provided in the female terminal 10, but the present invention is applied to the cylinder 16 (provided in the male terminal 26 (terminal)). It is good also as a structure applied to the box.
