As shown in Figure 6, when the shaft 3 is first inserted into the larger hole 4a of the terminal 40 at the dashed line position and then slid toward the smaller hole 4b, the shaft 3 is inserted into the position shown by the solid line. come into position. At this time, the head of the shaft 30 is pressed into contact with the recess of the contact 6 by the elastic force of the contact 6.

A cross-sectional view of the state at this time seen from another angle is shown in Figures 1-5.

As described above, when the main body 1 and the speaker box 2 are used together, the engagement between the shaft 3 and the terminal 4 allows
Electrical connections are made.

However, if these are separated, electrical connection cannot be made through the shaft 6 and the terminal 4, so another means is provided.

This will be explained using Figure 7. Figure 7 is a perspective view of the main body 1 and the speaker box 2 seen from the back side.

A lead wire 9 is provided on the back side of the speaker box 2 and has one end electrically connected to the contact 6 and a plug 8 attached to the other end. On the other hand, a jack 10 electrically connected to the shaft 63 is provided on the back side of the main body 1.
is provided. When using the main unit 1 and speaker box 2 apart, take out the lead wire 9 from the speaker box 2 and insert the plug 8 into the jack 10 on the main unit side.
Insert. In this way, the main body 1 and the speaker box 2 are electrically connected.

However, in the conventional device described above, the shaft 3, the terminal 4°, and the plug 8. A lead wire 9 and a jack 10 were required, which had the disadvantage of requiring a large number of parts (and thus increasing costs).Furthermore, the structural connection method was not easy, but rather difficult. This connection had problems with the reliability of the contact between the shaft and the terminal.Furthermore, the electrical performance could deteriorate due to the wiring method of the lead wire, making it difficult to work.
