FIG. 9 is a perspective view of the optical receiving terminal 1 in a movable state, and FIG. 9 is a side view of the optical receiving terminal 1 in a movable state. As shown in each of these drawings, the optical receiving terminal 1 is configured by providing an optical connector 10, a coaxial connector 20, and a photoelectric conversion unit (not shown) in a housing 30. In the following description, the direction shown in FIG. 1 is used as a reference, the Z direction is referred to as the height direction or the vertical direction, the X direction is referred to as the width direction or the horizontal direction, and the Y direction is referred to as the depth direction.

  The optical connector 10 is an optical input terminal for inputting an optical signal. The optical connector 10 can be configured in the same manner as a known optical connector as long as an optical cable can be connected and an optical signal input from the optical cable can be output to the photoelectric conversion unit. For example, the optical connector 10 is configured as an F04 type single-core optical fiber C1 connector (SC type connector) standardized by JIS 5973, and has a push-on type fastening structure based on a so-called slide lock structure.

  The coaxial connector 20 is an electrical output terminal that outputs an electrical signal. The coaxial connector 20 can be configured in the same manner as a known coaxial connector as long as a coaxial cable can be connected and an electric signal input from the photoelectric conversion unit can be output to the coaxial cable. For example, the coaxial connector 20 is configured as an F-type female connector for connecting an F-male coaxial connector attached to the tip of a coaxial cable.

  The photoelectric conversion unit is a photoelectric conversion unit that converts an optical signal input via the optical connector 10 into an electrical signal and outputs the electrical signal to the coaxial connector 20. The photoelectric conversion unit is configured to include a photodiode. The photodiode photoelectrically converts an optical signal input from the optical cable connected to the optical connector 10 and is connected to the coaxial connector 20. Output to. In practice, the photoelectric conversion unit is mounted on a circuit board accommodated in the housing 30. In addition to the photoelectric conversion unit, a known electrical component similar to that used for a conventional optical receiving terminal, such as a filter element, is mounted on the circuit board.

  The housing 30 is a basic structure of the optical receiving terminal 1, and houses a circuit board on which a photoelectric conversion unit is mounted. Here, the housing 30 is configured to include an electric side support portion 40 and a light side support portion 50.

  The electric side support part 40 supports the coaxial connector 20, and is formed as a hollow rectangular box-like body as a whole. The lower half portion (hereinafter referred to as the lower portion 41) of the electrical side support portion 40 is formed with a width and depth that is slightly smaller than the upper half portion (hereinafter referred to as the upper portion 42). As a result, a step 43 is formed between the lower portion 41 and the upper portion 42. The upper side portion 42 of the electrical side support portion 40 accommodates the circuit board and the photoelectric conversion portion described above, and the coaxial connector 20 is fixed to the upper surface thereof. Further, the lower portion 41 of the electric side support portion 40 is formed in a hollow shape, and the light side support portion 50 will be described later in a state in which the housing 30 is rotated via the movable portion 60 described later. The central piece 52 can enter the lower portion 41. The electrical side support portion 40 is formed by molding from light metal or resin, for example.

  The optical side support part 50 supports the optical connector 10, and as shown in FIGS. 8 and 9, a central piece 52 and a pair of left and right side pieces 53 are integrally extended from the bottom piece 51. The bottom piece 51 is a rectangular plate-like body having a shape substantially coinciding with the bottom shape of the electric side support portion 40, and the optical connector 10 is fixed to the bottom piece 51. The central piece 52 is a square plate-like body having a front shape substantially matching the front shape of the lower portion 41 of the electric side support portion 40. Each of the pair of side pieces 53 is a rectangular plate-like body having a side surface shape substantially matching the side surface shape of the lower portion 41 of the electric side support portion 40. The light-side support portion 50 is formed, for example, by punching plate-like light metal or resin and then bending the portions corresponding to the central piece 52 and the side piece 53. The optical connector 10 and the photoelectric conversion unit are connected via a line (an optical line or an electric line) (not shown) that extends through the light side support part 50 and reaches the lower part 41 of the electric side support part 40. Yes. This line has a sufficient margin length so that an optical signal input from the optical cable to the optical connector 10 can be output to the photoelectric conversion unit even when the housing 30 is rotated via the movable unit 60 described later. It is formed with strength.

  Next, a circuit configuration example of the optical receiving terminal 1 will be described. FIG. 7 is a circuit diagram of the optical receiving terminal 1. In FIG. 7, the optical receiving terminal 1 operates by supplying power from various devices such as a TV receiver connected to the optical receiving terminal 1, or when the power supply is stopped due to a power failure or the like, no power is supplied. It is comprised so that operation | movement is possible.

  Specifically, power is supplied to the optical receiving terminal 1 from the various devices such as a TV receiver connected to the optical receiving terminal 1 via the coaxial cable via the coaxial cable and the coaxial connector 20. By this power supply, a reverse bias is applied to the PD (Photo Diode) via the choke coil L1 and the protective resistor R1. The optical signal input to the optical connector 10 is photoelectrically converted by this PD into an electrical signal, and this electrical signal is output from the coaxial connector 20.

  The resistor R2 functions as a matching means for performing impedance matching with a subsequent device connected to the coaxial connector 20. That is, since the impedance when the optical receiving terminal 1 is viewed from the coaxial connector 20 side is the resistance value of the resistor R2, impedance matching is performed by matching the resistance value of the resistor R2 with the impedance of the subsequent device. be able to.

  Capacitor C1 and capacitor C2 are AC coupling capacitors. Ideally, the capacitors C1 and C2 are made infinite and the direct current component is dropped, so that only the alternating current component (RF signal) can be output to the coaxial connector 20. The position of the capacitor C1 can be arbitrarily changed as long as the resistor R2 can be AC-coupled. The coil L2 is an inductor that circulates the direct current component of the PD current to the PD.

  The switch SW is a switching unit that applies a reverse bias to the PD by opening the line when power is supplied, and closes the PD in a DC manner by closing the line when no power is supplied. This switch SW is specifically configured as a manual switch, and for example, the user can manually operate the switch SW as necessary. The switch SW is provided, for example, so as to be exposed to the outside of the housing 30 so that the user can operate it manually (however, the illustration of the switch SW is omitted except for FIG. 7).

  In the circuit configured as described above, at the time of power feeding, the switch SW is opened, and as described above, a reverse bias is applied to the PD, and a signal photoelectrically converted by the PD is output from the coaxial connector 20. .

  On the other hand, when no power is supplied due to a power failure or the like, the switch SW is closed and the PD functions as a photoelectric conversion means used in a no-bias mode without applying a reverse bias. That is, when light energy exceeding the energy band cap is incident on the PD, this light energy is absorbed by the depletion layer, and conduction electrons and holes are generated and drifted. Electric power is generated. As for this electromotive force, only the AC component is output to the coaxial connector 20 by dropping the DC component by AC coupling by the capacitor C1 and the capacitor C2. Therefore, the RF signal can be extracted from the coaxial connector 20 and supplied to the subsequent stage.

  In particular, in this circuit, the PD is short-circuited in a DC manner by closing the switch SW, so that the inter-terminal capacitance of the PD can be made as small as possible when no power is supplied, and the high-speed performance of the PD is maximized. Can be kept to a limit.

  Next, the movable structure of the optical receiving terminal 1 will be described. The housing 30 is provided with a movable part 60. The movable portion 60 is a movable means that can relatively displace the optical connector 10 and the coaxial connector 20, and either the optical connector 10 or the coaxial connector 20 (here, the optical connector 10) is connected to the optical connector 10 or the optical connector 10.

  The housing 30 is provided with a fixing portion 70. The fixing portion 70 is a fixing means that makes the optical connector 10 and the coaxial connector 20 relatively undisplaceable. One of the optical connector 10 and the coaxial connector 20 (here, the optical connector 10) is connected to the optical connector 10 or The other side of the coaxial connector 20 (here, the coaxial connector 20) can be fixed. Specifically, the fixing portion 70 includes a fixing protrusion 71 and a fixing piece 72. The fixing protrusion 71 is provided on the outer surface (here, the left and right side surfaces) of one of the light-side support portion 50 and the electric-side support portion 40 (here, the electric-side support portion 40), and is a short cylinder. It is a solid body and is formed integrally with the electric side support portion 40. The rotating piece 62 is provided on the other of the light side support part 50 or the electric side support part 40 and is fixed to the fixing protrusion 71. Here, the fixed piece 72 is constituted by the left and right side pieces 53 of the light side support portion 50. That is, each of the left and right side pieces 53 is provided on the other of the light side support part 50 or the electric side support part 40 (here, the light side support part 50) and has a shape corresponding to the fixed protrusion 71. The light-side support portion 50 is fixed to the electrical-side support portion 40 by locking the fixing protrusion 71 in the through-hole 53b.

  The housing 30 is provided with a cover piece 80. The cover piece 80 is disposed on the outer stepped portion 43 on one of the light side support portion 50 and the electric side support portion 40 (here, the electric side support portion 40) in the non-movable state, It is flush with the outer surface of one of the part 50 or the electric side support part 40 (here, the electric side support part 40). Here, the cover piece 80 is constituted by a central piece 52 and a side piece 53 of the light-side support portion 50. That is, the central piece 52 and the side piece 53 are formed with a thickness substantially equal to that of the stepped portion 43, arranged in the stepped portion 43 in a non-movable state, and flush with the outer surface of the electric side support portion 40. Thus, the stepped portion 43 is covered in an unexposed state with respect to the outside.

Further, in this state, the fixing protrusion 71 is locked in the through hole 53b, and the light side support portion 50 is fixed to the electric side support portion 40. Therefore, the light side support portion 50 is fixed to the electric side support portion 40. Inadvertent rocking is prevented.
