basic configuration in which four signal input electrodes 12, 13, 14, 15 electrically isolated from
each other are provided on the tip side.
[0007]
More specifically, the signal input electrodes 12, 13, 14 and 15 are formed by dividing the pin

[0008]
Further, in the present embodiment, the connection terminals 19 to 23 are inserted into the base
end portion of the pin jack 10 and the electrodes 11 to 15 of the pin jack 10 are electrically
connected (FIG. 3). And a positioning projection 25 for positioning the pin jack 10 and the
connector 24 about the axis in engagement with the connector 24 having the reference. The
positioning projection 25 is engaged with a locking groove 26 formed at the tip of the connector
24 to obtain the above-described function.
[0009]
Further, as shown in FIG. 3, the ground terminal 27 is connected to the connection terminal 19,
the light channel signal line 28 is connected to the connection terminal 20, and the left channel
10-05-2019

signal line 29 is connected to the connection terminal 22. Further, the light channel signal line
28 is selectively connected to the connection terminal 21 via the contact a of the changeover
switch 30, and the rear light channel signal line 31 is selectively connected via the contact b of
the changeover switch 30. Further, the left channel signal line 29 is selectively connected to the
connection terminal 23 via the contact a of the changeover switch 32, and the rear left channel
signal line 33 is selectively connected to the connection terminal 23 via the contact b of the
changeover switch 32. It has become.
[0010]
Then, the changeover switches 30 and 31 are connected in an interlocked state to constitute a 2channel and 4-channel changeover switch 34 as a whole, and these changeover switches 30 and
31 do not receive an operating force. , Is always held in the state of being connected to the
contact a side.
[0011]
On the other hand, the tip of the electrical insulating plate 18 disposed along the axial direction
of the pin jack 10 is made to project from the tip of the pin 10 a, and when the pin jack 10 is
inserted into the connector 24, the two channels In cooperation with the four-channel
changeover switch 34, the operation member 18a is configured to switch the changeover
switches 30 and 32 to the contact b side.
[0012]
When the pin jack 10 according to this embodiment configured as described above is inserted
into the connector 24 so that the positioning protrusion 25 and the locking groove 26 are fitted,
the ground electrode 11 of the pin 10 a and the signal input electrode 12 ( Signal input electrode
13 (rear light channel), signal input electrode 14 (left channel), and signal input electrode 15
(rear left channel) are connected to the connection terminal 19 of the connector 24, the
connection terminal 20, the connection terminal 21 While being electrically connected to the
connection terminal 22 and the connection terminal 23, the changeover switches 30 and 32 of
the 2-channel and 4-channel changeover switch 34 are switched to the contact b side by the
operation member 18a.

signal line 28, and the signal input electrode 13 (rear light channel) is rear A signal input
electrode 14 (left channel) is connected to the light channel signal line 31, a left channel signal
line 29 is connected, and a signal input electrode 15 (rear left channel) is connected to the rear
left channel signal line 33. It becomes possible to input an independent signal to.
Moreover, since the four types of signals described above can be output by one pin jack 10, only
one connector 24 is required, so that the mounting space can be reduced, and the size and
thickness of the device can be reduced. Never get in the way of
[0014]
On the other hand, in the present embodiment, when the pin jack 1 of the conventional structure
shown in FIG. 4 is inserted, the pin jack 1 does not have the operation member 18 a like the pin
jack 10 of the present embodiment. The switching operation of the 2-channel / 4-channel
changeover switch 34 of the connector 24 is not performed, and the changeover switches 30 and
32 are held on 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 also for signal transmission and reception using a
conventional two-channel pin jack.
[0015]
The shapes, dimensions, and the like of the constituent members shown in the embodiment are
merely examples, and various changes can be made based on design requirements and the like.
For example, as shown in FIG. 5, the signal input electrodes 40, 41, 42, 43 may be configured by
axially dividing the pin 44 into four.
It is also possible to use two of the four signal transmission paths as audio signals and the other
two as signal lines for digital signals for information processing, for example.

[0016]
As described above, according to the four-speaker compatible pin jack according to any one of
claims 1 to 8 of the present invention, the four signal input electrodes provided on the pin jack
can be used. Four independent signaling pathways can be formed. As a result, only one connector
for connecting the pin jack to the device can be used, and the mounting space can be made as
small as possible, making it possible to apply the device to the downsized and thinned device. In
particular, as described in claim 2, by forming the signal input electrode by dividing the pin into
two each in the radial direction and the axial direction, the outer shape is made the same as the
conventional pin jack 4 Since one signal transmission path can be secured, compatibility with the
conventional structure can be secured.
