As shown in fig. 1 and 2, an optical signal collecting apparatus for an optical communication device automation device includes: a housing 1 having an interior cavity 12, a photodetector 2, a circuit assembly 3, and a fixture 4.

A first opening 11 is formed on the wall surface of the casing 1; one end of the photodetector 2 is disposed through the first opening 11, and specifically, one end of the photodetector 2 may pass through the first opening 11 and protrude outside the housing 1, and one end of the photodetector 2 may also be disposed in the first opening 11 but not protrude outside the housing 1. After entering the first opening 11, an external optical signal is detected and sensed by the photoelectric detector 2, and the other end of the photoelectric detector 2 extends into the inner cavity 12; typically, the circuit assembly 3 is fixedly disposed within the interior cavity 12. The circuit component 3 may be a printed circuit board assembly (i.e., a PCBA board). The circuit assembly 3 includes a printed circuit board (i.e., a PCB board) and electronic components disposed on the printed circuit board. The circuit component 3 is electrically connected with the photoelectric detector 2 so as to convert the optical signal detected by the photoelectric detector 2 into an electric signal and send the electric signal to a control system (not shown) connected with the optical signal acquisition device; the fixing part 4 is fixedly arranged on the machine shell 1, and the quick assembly and disassembly of the machine shell 1 and the machine frame are realized through the quick assembly and disassembly of the fixing part 4 and the machine frame.

Mounting 4 can be magnet, sucking disc or magic subsides, compares in bolted connection's form, need not additionally prepare many parts and bolt instrument, and easy dismounting. Taking a suction cup as an example, the fixing piece 4 is tightly attached to the frame by air pressure to realize fixing. Taking the magic tape as an example, the fixing piece 4 can be one of a son surface or a mother surface, the other of the son surface or the mother surface is fixed at a position needing to be fixed on the rack, the fixing mode can be binding or glue bonding, and the fixing is realized by tightly attaching to the rack by air pressure. Taking the fixing member 4 as an example, a fixing hole is formed at one end of the base 16 far away from the shell 14, the fixing member 4 is embedded into the fixing hole, and the fixing member 4 is magnetically connected with the frame of the steel structure, so that rapid fixing and assembling and disassembling are realized.

In a possible embodiment, as shown in fig. 1 and 2, the housing 1 includes a base 16, two end caps 13 and a housing 14 with two open ends, the two end caps 13 correspondingly cover the openings of the housing 14 to form a closed inner cavity 12, and the first opening 11 is disposed on one of the end caps 13, so as to facilitate the insertion of one end of the photodetector 2; the base 16 is connected with the shell 14 in an integrated manner, so that the strength is good, and the base 16 and the shell 14 can also be detachably connected, so that the manufacturing process of the casing 1 can be reduced, for example, the connection by bolts is adopted. Specifically, a through hole 161 is formed in the base 16, a threaded hole (not shown) is formed in a side wall surface of the housing 14, and a bolt (not shown) is screwed into the threaded hole after passing through the through hole 161.

Fixing piece 4 sets firmly on base 16, and base 16 realizes fixedly through fixing piece 4 and frame, and then fixes circuit module 3 and photoelectric detector 2 in casing 14, and photoelectric detector 2 accomplishes the detection of light signal, and circuit module 3 accomplishes the photoelectric signal conversion.

It can be understood that, since different photodetectors 2 detect optical signals with different wavelengths, the circuit components 3 corresponding to the photodetectors 2 may also have different sizes, lines, and other electronic components attached thereto, so that different circuit components 3 and photodetectors 2 correspond to different housings 14, and a plurality of housings 14 correspond to one base 16, so as to reduce the cost of the housing 1; in addition, when the photoelectric detector 2 and/or the circuit component 3 are damaged, only the shell 14 needs to be replaced, the base 16 does not need to be replaced, and maintenance is facilitated.

In a possible embodiment, the optical signal collecting device includes a wire plug, and the other end cover 13 is formed with a second opening 15, and the wire plug is inserted into the second opening 15 and electrically connected to the circuit component 3.

One possible implementation mode is that the shell 14 is cylindrical, a positioning step is formed on the inner wall of the shell 14, the circuit assembly 3 is arranged on the positioning step, and the inner wall of the circuit assembly 3 and the inner wall of the shell 14 are prevented from having large gaps due to the fact that the circuit assembly 3 is fixedly connected through bolts, shaking occurs, and then the photoelectric detector 2 or the circuit assembly 3 is influenced, and damage is caused.

In one possible embodiment, the housing 14 is a metal housing and the end cap 13 is a metal cover plate. Specifically, the housing 14 may be an aluminum alloy housing, and the end cover 13 is an aluminum alloy cover plate, which is not only convenient to process, strong in strength, but also light in weight, and prevents the base 16 from being loosened from the frame under the action of gravity.

The shell 14 is connected with the end cover 13 through bolts; therefore, the photoelectric detector 2 and the circuit component 3 are sealed in a metal frame body, and external electromagnetic interference is shielded, so that the detected optical signal is accurate.
