グコネクタ１６が構成される。In FIG. 4, a wire material having conductivity and elasticity is wound in a space-like manner in the shape of a truncated cone coil having a small winding diameter on the upper end side to form a spring portion 10a, and the lower end side thereof is a coil shaft. The spring terminal 10 is formed by bending it 90 degrees in the direction to form the insertion portion 10b. Then, a hole 12b is formed in the circuit board 12 on the back surface of which the circuit conductor 12a is disposed, and the insertion portion 10 of the spring terminal 10 is formed.
b is inserted, and the insertion portion 10b protruding from the back surface and the circuit conductor 12a are appropriately soldered 14. Therefore, the insertion portion 10b of the spring terminal 10 is electrically connected and fixed to the circuit conductor 12a of the circuit board 12. Therefore, the circuit board 12 and the spring terminal 10 form a spring connector 16.

る。In the conventional example shown in FIG. 4, when the soldering 14 is performed with the insertion portion 10b inserted in the hole 12b, the spring terminal 10 is lifted from the circuit board 12 and soldered. As a result, the stability of the spring terminal 10 may be deteriorated. Further, there is no problem if the position of the insertion portion 10b is coaxial with the coil axis of the spring terminal 10, but if it is deviated, the coil axis position of the spring terminal 10 varies with respect to the hole 12b. Further, the diameter of the hole 12b is small as long as the wire rod of the insertion portion 10b can be inserted, and is small, and it is difficult to form the hole. Then, in order that the insertion portion 10b can be smoothly inserted without buckling, the diameter of the hole 12b needs some dimensional margin with respect to the diameter of the wire. However, this dimensional margin deteriorates the positional accuracy of the spring terminal 10.

However, in the electrical connection between the circuit conductors of the circuit board, the plurality of terminals may be arranged at 0.8 mm pitch or even 0.5 mm pitch, and the positional accuracy of the spring connector 16 is important. It becomes a problem.
