なること等の欠点があつた。 In the conventional connection terminal of this type, as shown in Fig. 1, a pair of arc-shaped copper foil patterns B 1 and B 2 are printed in a circular shape on a circular substrate A, spaced apart from each other. . As shown in FIGS. 2 and 3, this board A is attached to the bottom surface of a yoke D constituting a dynamic headphone unit C.
A lead wire H of the voice coil G is arranged between the yoke D and the magnet E and is fixed to the diaphragm F.
is pulled out from the upper surface of a flange-shaped yoke D through a damper I, and then connected to copper foil patterns B 1 and B 2 on a substrate A by soldering or the like. However, in the structure of the board A as described above, the lead wire H is introduced into the copper foil patterns B 1 and B 2 via the edge part A 1 of the board A, as shown in FIG. As shown in the figure, if an external part J supporting the headphone unit C comes into contact with an edge part A1 of a board A, there is a risk that the lead wire H will be cut between the edge part A1 and the external part J. . Therefore, in order to prevent this breakage, adhesive K was applied to the lead wire H in contact with the edge portion A1 to protect the lead wire H.
There were disadvantages such as the need for adhesive K, the adhesive K adhering to other parts, and the need for additional work for this adhesion.
