The portion corresponding to b, the ring portion 23c, and the insulating portion 53 has the metal body 57 exposed, and serves as an electrode portion dedicated to identification. With such a configuration, the optical plug insulation identification pattern 43 is formed.

Further, the shape of the small single-headed electrical plug 45 for transmitting digital signals is
3 but with the exception of the sleeve 23a
Is provided with an insulating portion 59 for identifying a digital electric plug.

Thus, each of the plugs 23, 27, 45
By changing the position and width of each identification insulating part without affecting each transmission, each insulation identification pattern 43, 44, and 46 is different, so that each transmission system can be identified.

The metal plates 24b, 2 of the electric connection terminals 24
4c and 24d are electric signal transmission terminals similar to those of the first embodiment. The metal plate 24b is, as shown in FIGS. 8 and 9, disposed in contactable position with the metal body 57 of the tip portion 23b and the optical plug 27 of the electric plug 23,45. The metal plate 24c is provided with a ring portion 23c of the electric plugs 23 and 45.

And between the metal plate 24d and the metal plate 62 can be electrically connected to the electrode portions 23a and 23d of the electric plug 23, respectively.

When the digital electric plug 45 is inserted, as shown in FIG. 16, the metal plate 24d and the metal plate 62 can be electrically connected via the ring 23d of the single-headed electric plug. However, since the metal plate 61 is in contact with the insulating portion 59, the metal plate 24d and the metal plate 61 are insulated and cannot conduct.

By the combination of the above-mentioned continuity and non-conduction, it is possible to identify each plug type of the shared optical transmission device. As described above, the plugs 23, 27, and 45 can be automatically identified by the system identification means 41. However, before insertion into the insertion hole 36, the insulation identification patterns 43, 4
Needless to say, 4,46 can be visually identified.

[Third Embodiment] In the above-described second embodiment, a function of identifying whether or not a plug is inserted and a transmission method is provided.

Therefore, in the present embodiment, a short circuit between different electrical connection terminals is prevented to prevent an electrical trouble, and a terminal as the insertion identification means 42 is brought into contact without interposing the outer peripheral surface of the plug, so that external digital The purpose is to prevent circuit breakage and runaway.

The shared optical transmission device of this embodiment is similar to that shown in FIG.
And the optical plug 27, the three-pole analog electrical plug 23 of Figure 24, intended to selectively use the digital electrical plug 45 of Figure 15, as in FIGS. 17 to 21, electrical connection terminal 24 and the identification It is premised that a plurality of pairs of terminals 47 are provided by providing two terminals for each of the same number and corresponding to each other one by one. This is the same as the second embodiment except that at least some of the terminals 24 and 47 are arranged in different pairs of terminals 24 and 47.
Insulation identification patterns 4 of the plugs 23 and 27 prevent the 47 from being short-circuited through the outer peripheral surfaces of the plugs 23 and 27.
The position is shifted with respect to 3, 44.

This will be described in detail. As shown in FIG. 22, the light
If you want to use the plug 27, the metal plate 24b and the metal plate 24

That is, the insertion identification means 42 includes an outer terminal (second terminal) 71 disposed at a position where the insertion plug 36 is not in contact with the used plug 23, 27, 45 in the insertion hole 36 of the holder 25, and an inner terminal 71 of the outer terminal 71. And a mechanical contact composed of an inner terminal (first terminal) 72 disposed at the same position.

Here, the electrical connection terminals 24 and the like are connected to each plug 2

[Fourth Embodiment] As shown in FIGS. 25 to 29, a shared optical transmission apparatus according to a fourth embodiment of the present invention is capable of selecting an optical system, a digital electric system, and an analog electric system. In particular, the method is the same as that of the above-described embodiments. In particular, the method identification means 41 for identifying which method the plug inserted into the insertion hole 36 of the holder 25 is, Insertion identification means 4 for identifying whether or not it has been inserted into insertion hole 36
2 is provided in the same manner as the second and third embodiments and the third embodiment, and the electrical connection terminals 24 and the identification terminals 47 and the like have the same arrangement configuration as the third embodiment. However, this embodiment is different from the above embodiments in the current path for checking the electrical continuity of the terminals 24 and 47.

[0064] That is, the photoelectric shared transmission apparatus of this embodiment, as shown in FIG. 30, the inner terminal of the inserted identification means 42 (first
Terminal) 72 is grounded to the ground (GND) as a ground terminal, also metal plates 61 and 62 and the outside terminal
(2nd terminal) 71 is a resistance element (pull-up resistance) 8
1, 82 and 83 are connected to a constant voltage power supply Vref, respectively. As a result, the inner terminal 72 is
During the contact with the outside terminal 71, the potential (output) V71 of the outside terminal 71 is low because the outside terminal 71 is short-circuited to the ground, but when the inside terminal 72 is not in contact with the outside terminal 71, the potential of the outside terminal 71 is low. (Output) V71 goes high. Further, the inner terminal 72 is connected to the ring portion 2 of the electric plugs 23 and 45.
3d and the metal plate 62 is in contact with the ring portion 23d of the electric plugs 23 and 45, the metal plate 62 is short-circuited to the ground, so that the potential V62 is low. Is in a non-contact state with the ring portion 23d of the electric plugs 23 and 45, the potential V6 of the metal plate 62 is
2 goes high. Similarly, the inner terminal 72 is
3, while the metal plate 61 is in contact with the sleeve 23a of the electrical plug 23, the potential V61 is low because the metal plate 61 is short-circuited to the ground. The metal plate 61 is in a non-contact state with the portion 23 d or the metal plate 61 is
The potential V61 of the metal plate 61 becomes high when it is brought into a non-contact state with a.

The other structure is the same as that of each of the above embodiments. For example, the shape of each of the plugs 23, 27, and 45 is formed to have a single head and a constriction as in the first embodiment. . Further, the depth L1 of the insertion hole 36, the length L2 of the insertion portion to be inserted into the insertion hole 36 of the optical fiber plug 27, the insertion hole 36 of the small single-head plug 23 or the plug 45 having a shape similar thereto. The relationship with the length L3 of the insertion portion to be inserted into L1>L2>L1>L2> as in the first embodiment.
L3.

FIG. 31 shows plugs 23, 27, 45
FIG. 31 shows potentials V71, V62, V61 of the outer terminal 71 and the metal plates 61, 62 with respect to the types of FIG.
“H” in the middle indicates a high state, and “L” indicates a low state.

First, when the analog electric plug 23 is inserted, the inner terminal 72 is pushed by the plug 23 and comes into contact with the outer terminal 71, and the outer terminal 71 is short-circuited to the ground. Go low. Further, since the metal plate 62 contacts the ring portion 23d of the electric plug 23, the metal plate 62 is short-circuited to the ground via the ring portion 23d of the electric plug 23 and the inner terminal 72, and the potential V62
Goes low. Further, since the ring portion 23d of the plug 23 and the sleeve portion 23a are continuous as a metal portion, the metal plate 61 is short-circuited to ground via the sleeve portion 23a, the ring portion 23d and the inner terminal 72 of the electric plug 23, and the potential V61 Goes low. That is, all potentials V71, V62, V of the outer terminal 71 and the metal plates 61, 62
61 goes low.

Next, when the digital electric plug 45 is inserted, the outer terminal 71 and the inner terminal 72 are electrically connected similarly to the analog electric plug 23.
The metal plate 62 and the inner terminal 72 are electrically connected via the ring portion 23d of the plug 45. However, since the portion corresponding to the sleeve portion 23a of the analog electrical plug 23 is the insulating portion 59, The metal plate 61 and the inner terminal 72 are not electrically connected. Therefore, the potentials V71 and V62 of the outer terminal 71 and the metal plate 62 become low,
The potential V61 of the metal plate 61 becomes high.

[0069] When the optical plug 27 is inserted, since the portion corresponding to the ring portion 23d and the sleeve portion 23a of the analog electrical plug 23 is an insulating section 56, electrical inner terminal 72 Are connected only to the outer terminal 71. That is, the potential V of the outer terminal 71
Only 71 is low, and the potentials V61 and V62 of the metal plates 61 and 62 are high.

Then, any of the plugs 23, 27, 45
Is not inserted, the inner terminal 72 is
The metal plate 61, the outer terminal 71, and the metal plate 62 are not all connected to the ground because they do not come into contact with each other.
1, V62 and V61 are all high.

As described above, by detecting the potentials V61, V62, V71 of the metal plate 61, the metal plate 62 and the outer terminal 71, the types of the inserted plugs 23, 27, 45 and the presence / absence of the plug insertion are identified. be able to. This identification may be performed by an external circuit such as a microcomputer of the mounting board.

When a voltage is applied to the sleeve portion 23a and the ring portion 23d of the electric plugs 23 and 45, electric signals other than the original signals input to and output from the plugs 23 and 45 are input. Then, noise is mixed into the original signal. However, in the present embodiment, since the inner terminals 72 are grounded, the plugs 23, 27, and 45 can be connected with a small amount of current.
Type and the presence or absence of plug insertion can be identified. In this case, it is not necessary to apply a high voltage to the metal plate 61, the outer terminal 71, and the metal plate 62.
Noise of the plugs 23, 27, and 45 generated by applying a high voltage to 7, 45 can be reduced.

[0073] According to Fifth Embodiment] The structure of I that photoelectric shared transmission apparatus in the first embodiment to the fourth embodiment, FIGS. 1 to 4, 8 to 1
17 and FIG. 17 to FIG. 21, an optical fiber cable for optical transmission is mounted on a holding body 25 containing a plurality of metal plates 24a to 24d that are connected to a small single-headed electrical plug for electric transmission and perform electric exchange. The optical semiconductor element 22 which transmits and receives light between the holder 25 is housed and held, and the external connector 26 is bent once before reaching the bottom surface of the holder 25 and is folded.
5 are arranged so as to be flush with the bottom surface. For this reason, the height from the mounting substrate 84 of the shared optical transmission device is determined by the height of the transparent resin 22b of the optical semiconductor element 22 and the distance from the bottom surface of the transparent resin 22b of the external connector 26 to the bending position. Determined by the sum. Then, the distance from the bottom surface of the translucent resin 22b to the bending position,
This hindered a reduction in height.

Therefore, as shown in FIGS. 32 and 33, a proposal example in which the external connector 26 is arranged perpendicular to the bottom surface of the holder 25 and inserted directly into the mounting board 84 is also conceivable. However, in the proposal example shown in FIGS. 32 and 33, the height from the mounting substrate 84 of the shared optical transmission device is higher than the height of the light-transmitting resin 22b of the optical semiconductor element 22 and the bottom of the light-transmitting resin 22b. It is determined by the total of the external connector 26 and the distance to the tie bar uncut portion 26b. Therefore, it has become a limiting factor when further height reduction is desired. The shared optical transmission device of the present embodiment is configured so as not to be restricted by the height of the translucent resin 22b in order to enable a reduction in height.

That is, as shown in FIGS. 34 and 35, the shared optical transmission device of the present embodiment has a drawing surface (bottom surface) 85 from which the external connector 26 of the optical semiconductor element 22 is drawn.
Is the end face (bottom face) 8 of the holder 25 in contact with the mounting board 84.
6 and the external connector 2
6 is a drawer 87 drawn out perpendicular to the end face 86 of the holder 25, and a bent part 88 bent from the tip of the drawer 87 parallel to the end face 86 of the holder 25. The drawing dimension T1 of the drawing section 87 is set substantially equal to the thickness dimension T2 of the mounting board 84. That is, the external connector 26 is configured so that the lead-out portion 87 penetrates through the mounting substrate 84 and the tip of the bent portion 88 is pulled out from the back surface of the mounting substrate 84 in the lateral direction. For this reason, the mounting board 84 includes the metal plate 2
Not only a through hole 91 for an electric connection terminal passing through 4a to 24d, 61, and 62 but also a through hole 92 for a connector passing through the external connector 26 is used.

In the above configuration, when mounting on the mounting board 84, first, as shown in FIGS. 36 and 37, the bent portion 88 of the external connector 26 is connected to the connector through hole 9 of the mounting board 84.
Insert into 2. Then, when the drawer 87 is inserted into the connector through hole 92, the holding body 25 is pushed down while rotating downward. Then, while inserting the drawer portion 87 into the connector through hole 92 as it is, the metal plate 2
4a to 24d are inserted into the through holes 91 for electric connection terminals.
Thereafter, the metal plates 24a to 24d may be connected to a printed wiring circuit (not shown) on the back surface of the mounting board 84 by soldering or the like.

When the extraction surface 85 of the optical semiconductor element 22 and the bottom surface 86 of the holder 25 are arranged on substantially the same plane, the extraction surface 85 of the optical semiconductor element 22 comes into contact with the surface of the mounting substrate 84. And the optical semiconductor element 22 and the mounting substrate 84 as in the first to fourth embodiments.
Can be prevented from being generated. Therefore,
The height of the optical semiconductor element 22 from the front (upper) surface of the mounting substrate 84 can be reduced by the length of the lead-out portion 87, and therefore, the holder 25
, The height of the shared optical transmission device can be reduced, and in particular, the portable device can be made thinner.

The present invention is not limited to the above-described embodiment, and it goes without saying that many modifications and changes can be made to the above-described embodiment within the scope of the present invention.

[0079] For example, in the first embodiment, the optical plug 27
The distance between the tip surface of the optical semiconductor device 22 and the front surface of the optical semiconductor element 22 is about 0.2 m.
Although the distance was set to m, the optical characteristics of both can be favorably maintained within a range of 0.0 mm to 0.5 mm.

In the first embodiment, the four-pole type analog plug 23 has been described as an example. However, the present invention may be applied to a three-pole type or a two-pole type, for example. Conversely, in the second embodiment and the third embodiment,
Although the three-pole type is described as an example of the analog electrical plug 23, the invention may be applied to, for example, a four-pole type or a two-pole type.

Further, as shown in FIGS. 38 and 39, in order to be able to cope with solder reflow, the direction of taking out the metal plate from the holding body may be changed in consideration of the material of the optical semiconductor element and the like. .

Furthermore, the inner terminal 72 of the third embodiment and the fourth embodiment uses a bent piece having elasticity. For example, the outer terminal 71 is disposed above the holder 25 and the inner terminal 72 is disposed. May be arranged at the upper part of the insertion hole 36 so as to be detachable from the outer terminal 71, and may be brought into contact with the plugs 23, 27 and 45 by the weight of the inner terminal 72.

The resistance element 8 used in the fourth embodiment
1, 82 and 83 use ordinary resistors, but instead may use semiconductor elements such as diodes or capacitors or the like.

Further, in the fourth embodiment, the outer terminal 71
And one end of a constant voltage power supply Vref
Are connected to the pull-up resistors 81, 82, and 83, but instead of the pull-up resistors 81, 82, and 83, as shown in FIG.
The constant current power supply Ai is connected to the first and second terminals 62 and the outer terminals 71, and the resistance elements 81, 82 and 83 are connected to the connection intermediate points between the constant current power supply Ai and the respective metal plates 61 and 62 and the outer terminals 71. Good. In this case, the inner terminal 72 is
When the outer terminal 71 is short-circuited to the ground, current does not flow through the resistance element 81 while the outer terminal 71 is short-circuited to the ground. , 62 are short-circuited to the ground, so that no current flows through the resistance elements 82, 83. On the other hand, when the inner terminal 72 is not in contact with the outer terminal 71, the current from the constant current power supply Ai flows to the pull-up resistor 81 side.
Also, even if the inner terminal 72 is in contact with the outer terminal 71,
When there is no conduction between the outer terminal 71 and the metal plates 62, 61, current flows through the resistance elements 82, 83. in this way,
By detecting whether or not a current flows through each of the resistance elements 81, 82, and 83, the inserted plugs 23, 27, and 4 are detected.
5 and the presence or absence of plug insertion can be identified.

[0085]

As it is clear from the description above, according to the present invention, according <br/> to the onset bright, as insertion identification means, for example, the second as described above
By using a mechanical contact composed of the first terminal ( outer terminal ) and the first terminal ( inner terminal ) , it is possible to judge whether or not the plug can be inserted without passing electricity to the outer peripheral surface of the used plug. Therefore, it is possible to prevent an electrical trouble such as a signal from an external digital circuit not giving noise to an electrical connection terminal on the analog side.

Further, it is possible to prevent a short circuit between different electrical connection terminals to prevent an electrical trouble, and to prevent an optical plug
It is necessary to stabilize the optical coupling with conductive elements efficiently.
Door can be.
