The basic configuration is provided with four insulated signal input electrodes 12, 13, 14, 15.

More specifically, the signal input electrodes 12 and 13
14 and 15 are formed by dividing the pin 10a into two in the radial direction and the axial direction, and are integrated via electric insulating plates 16, 17, and 18, thereby forming the ground electrode 11 Together with the pin 10a. In this embodiment, the signal input electrode 12 is a light channel and the signal input electrode 13
Are assigned to the rear right channel, the signal input electrode 14 is assigned to the left channel, and the signal input electrode 15 is assigned to the rear left channel.

In this embodiment, a pin plug
A pin jar having connection terminals 19 to 23 (see FIG. 3) into which the pin plug 10 is inserted and the respective electrodes 11 to 15 of the pin plug 10 are electrically connected to the base end of the pin 10.
With the pin plug 10 and the pin jack 2
4 is provided with a positioning projection 25 for positioning around the axis. And this positioning projection 25 is
Locking groove 26 formed at the tip of pin jack 24
, The above-described function is obtained.

A right channel signal line 28 is connected to the connection terminal 20, a left channel signal line 29 is connected to the connection terminal 22, and a right channel signal line is connected to the connection terminal 21 via a contact a of a changeover switch 30. The line 28 is also selectively connected to the rear right channel signal line 31 via the contact b of the changeover switch 30. Further, the connection terminal 23 is connected to the left side of the switch a through the contact a of the changeover switch 32. Channel signal line 2
9, a rear left channel signal line 33 is selectively connected via a contact b of the changeover switch 32.

The changeover switches 30 and 31
Are connected in an interlocked state, and as a whole,
The four-channel switch 34 is constituted, and these switches 30 and 31 are always kept connected to the contact a when no operation force is applied.

Meanwhile, the tip portion of the electrically insulating plate 18 disposed along the axial direction of the pin plug 10 is provided to protrude from the tip of the pin 10a, Pinji the pin plug 10
When inserted into the jack 24, the operating member 18 for switching the changeover switches 30 and 32 to the contact b side in cooperation with the 2 channel / 4 channel changeover switch 34.
a.

According to the present embodiment configured as described above.
Insert the pin plug 10 into the pin jack 24 and the positioning protrusion 2
5 and the locking groove 26 are inserted so as to fit each other,
Earth electrode 11 of the pin 10a, the signal input electrode 12 (right channel) signal input electrode 13 (rear right channel), signal input electrode 14 (left channel), and, the signal input electrode 15 (rear left channel), peak
Connection terminal 19, connection terminal 20, connection terminal 21, connection terminal 22, and connection terminal 23 of the connection jack 24, respectively.
The changeover switches 30 and 32 of the channel / 4 channel changeover switch 34 are switched to the contact b side.

In this state, the ground electrode 11 of the pin plug 10 is connected to the ground wire 27 of the pin jack 24, the signal input electrode 12 (light channel) is connected to the light channel signal line 28, and the signal input electrode 13 (rear light channel). To the rear light channel signal line 31,
The signal input electrode 14 (left channel) is connected to the left channel signal line 29, and the signal input electrode 15 (rear left channel) is connected to the rear left channel signal line 33, and independent signals are sent to the signal input electrodes 12 to 15. It becomes possible to input. In addition, since the four types of signals described above can be output by one pin plug 10, only one pin jack 24 is required, so that the mounting space can be reduced, and the size and thickness of the device can be reduced. There is no such thing as an obstacle.

[0014] On the other hand, in the present embodiment, when the pin plug 1 of the conventional structure shown in FIG. 4 has been inserted, the pimp
Since the lug 1 does not have the operating member 18a like the pin plug 10 of the present embodiment, the pin jack 24
The switching operation of the channel / 4 channel changeover switch 34 is not performed, and the changeover switches 30 and 32 are held at the contact a side, whereby the light channel signal line 28 is connected to the light channel electrode 4.
Only the left channel signal line 29 is connected to the left channel electrode 5.
Therefore, compatibility can be ensured even for signal transmission / reception using the conventional two-channel pin plug .

Note that the shapes, dimensions, and the like of each component shown in the above embodiment are merely examples, and can be variously changed based on design requirements and the like. For example, as shown in FIG. 5, the signal input electrodes 40, 41, 42 and 43 are connected to the pins 44.
Can be configured by dividing into four in the axial direction. Further, it is also possible to use two of the four signal transmission paths for audio signals and use the other two as signal lines for digital signals for information processing, for example.

[0016]

As described above, according to the first aspect of the present invention,
According to the four-speaker pin plug and the pin jack according to any one of the eighth to eighth aspects, four independent signal transmission paths can be formed by the four signal input electrodes provided on the pin plug . As a result, only one pin jack for connecting the pin plug to the device is required, and the mounting space is reduced as much as possible, so that the device can be applied to a miniaturized and thinned device. In particular, as described in claim 2, the signal input electrode is formed by dividing the pin into two in the radial direction and the axial direction, so that the outer shape of the signal input electrode is the same as that of the conventional pin plug . Since a signal transmission path can be secured, compatibility with the conventional structure can be secured.
