(Receptacle contact) 6 is formed. In the present embodiment, the terminal piece 61, the pair of side plates 62 and 62, and the blade receiving portion 6 including the pair of spring pieces 64 and 64 are integrally formed as the blade receiving spring 60. In the present embodiment, a metal material is used as the material of the blade receiving spring 60.
　端子片６１には、第１端子ねじ８ｃのねじ部が挿通される第１ねじ挿通孔６１ａが形成されている。図１Ｂの例では、第１ねじ挿通孔６１ａは、Ｕ状の切欠きであり、下側の端子片６１の端部に形成されている。 The terminal piece 61 is formed with a first screw insertion hole 61a through which the screw portion of the first terminal screw 8c is inserted. In the example of FIG. 1B, the first screw insertion hole 61 a is a U-shaped notch and is formed at the end of the lower terminal piece 61.
　端子片６１の第１表面側には、上述の第１ナット８ｄが配置されている。第１ナット８ｄは、端子片６１の他表面（第２表面）側（図１Ｂでは、下側）から第１ねじ挿通孔６１ａに挿通された第１端子ねじ８ｃのねじ部の先端部が螺合されている。言い換えれば、端子片６１の第２表面側には、第１端子ねじ８ｃの頭部が配置されている。なお、本実施形態では、端子片６１は、第１端子ねじ８ｃと第１ナット８ｄとともに、第１ねじ付き端子を構成している。 The first nut 8d described above is disposed on the first surface side of the terminal piece 61.
