Description

Technical Field

[0001] This utility model relates to a fiber optic FP sensor demodulation system, belonging to the field of sensor demodulation technology. Background Technology

[0002] In practical applications of fiber optic FP sensor demodulation systems, the connector is constantly exposed to the external environment. Due to the lack of effective dustproof design, dust easily penetrates the connector. Dust accumulation not only interferes with fiber optic signal transmission, reducing the accuracy and stability of sensor demodulation, but may also damage the precision electronic components inside the connector, shortening the equipment's lifespan. Furthermore, existing connector baffle structures are relatively simple and functionally limited, only providing basic shielding and failing to achieve stable fixation under different usage conditions. When the equipment is moved or subjected to external force, the baffle is prone to displacement, significantly reducing its dustproof effect. Therefore, a fiber optic FP sensor demodulation system is proposed. Utility Model Content

[0011] Preferably, a slider is slidably connected to the side wall of the outer casing and located on one side of the rotating groove by a spring. A pin is fixed on the side wall of the slider, and the end of the pin extends into the rotating groove. A first pin groove and a second pin groove are provided on the rotating frame, and the pin is movably engaged in the first pin groove or the second pin groove.

[0035] The present invention is illustrated below with specific embodiments, but these are not intended to limit the scope of the invention.

[0036] Example 1

[0037] like Figures 1-6 As shown in this embodiment, a fiber optic FP sensor demodulation system is provided, including a housing 1. The side wall of the housing 1 is provided with a plurality of sockets 101 for connecting plugs. In order to prevent dust from entering the sockets 101 when not in use, a dustproof component 2 is provided on the housing 1 and above the sockets 101. A plurality of dustproof components 2 are provided, and each dustproof component 2 corresponds to one socket 101.

[0038] The dustproof component 2 includes a rotating groove 201, a rotating frame 202, and a baffle 203. The rotating groove 201 is formed on the side wall of the housing 1. The rotating frame 202 is rotatably connected to the rotating groove 201. The baffle 203 is disposed on the rotating frame 202 and is used to cover the socket 101.

[0039] In actual use, when the socket 101 is not needed, the rotating frame 202 is rotated within the rotating groove 201, causing the baffle 203 to rotate synchronously until it covers the socket 101, effectively preventing dust from entering the socket 101. When the socket 101 needs to be used to insert a plug, the rotating frame 202 is rotated in the opposite direction, causing the baffle 203 to rotate and move away from the socket 101, exposing the socket 101. At this point, the plug can be easily inserted into the socket 101.

[0040] Example 2

[0041] Based on Example 1, this embodiment adds a structure for fixing the state of the baffle 203 to improve the stability of the system.

[0042] A slider 4 is slidably connected to the side wall of the outer casing 1, located on one side of the rotating groove 201, via a spring 3. A pin 401 is fixed to the side wall of the slider 4, with the end of the pin 401 extending into the rotating groove 201. The rotating frame 202 has a first pin groove 2021 and a second pin groove 2022, and the pin 401 is movably engaged in the first pin groove 2021 or the second pin groove 2022. The end of the pin 401 extending into the rotating groove 201 is spherical.

[0043] When it is necessary to fix the baffle 203 in the state of covering the socket 101, rotate the rotating frame 202. During the rotation, the rotating frame 202 will exert a pushing force on the pin 401. Since the slider 4 is slidably connected to the outer shell 1 through the spring 3, the pin 401 will drive the slider 4 to compress the spring 3, causing the pin 401 to temporarily exit its current position in the rotating groove 201. When the rotating frame 202 rotates to the point where the baffle 203 covers the socket 101, the first pin groove 2021 corresponds to the position of the pin 401. At this time, the spring 3 restores its elastic deformation, pushes the slider 4 to reset, and the slider 4 drives the pin 401 to insert into the first pin groove 2021, thereby fixing the rotating frame 202 and making the baffle 203 stably in the state of covering the socket 101.

[0044] When it is necessary to switch the baffle 203 to the open socket 101 state, the rotating frame 202 continues to rotate. The rotating frame 202 again exerts a pushing force on the pin 401. The pin 401 drives the slider 4 to compress the spring 3 and exit the first pin groove 2021. When the rotating frame 202 rotates to the baffle 203 open socket 101, the second pin groove 2022 corresponds to the position of the pin 401. The spring 3 pushes the slider 4 to reset, and the pin 401 is inserted into the second pin groove 2022, fixing the rotating frame 202 and making the baffle 203 stably in the open socket 101 state.

[0045] The end of the pin 401 is spherical. During the rotation of the rotating frame 202, the spherical end can reduce the friction between the pin and the rotating frame 202, making the pin 401 smoother when exiting and entering the pin groove, reducing wear and extending the service life of the component.

[0046] Example 3

[0047] Based on Example 2, this embodiment optimizes the structure of the baffle 203 and adds other functional components to the outer shell 1 to further improve the practicality of the system.

[0048] The baffle 203 is rotatably connected to the rotating frame 202 at its center. One end of the baffle 203 is a blocking part 2031, and the other end is an anti-detachment part 2032. A sealing ring 2033 for sealing is adhered to the side wall of the blocking part 2031, and a wire outlet groove 2034 for holding the plug wire is opened on the side wall of the anti-detachment part 2032. The wire outlet groove 2034 is U-shaped. In addition, a power port 102 and a switch 103 are provided on the side wall of the housing 1, heat dissipation fins 104 are provided on the upper surface, multiple lifting pads 105 are provided on the lower surface, and an indicator light 106 is also provided on the side wall.

[0049] During use, when no plug is inserted into the socket 101, the baffle 203 is rotated. Since the middle part of the baffle 203 is rotatably connected to the rotating frame 202, the shield 2031 can be rotated to a downward position. At this time, the shield 2031 covers the socket 101, and the sealing ring 2033 on the shield 2031 is tightly fitted with the side wall of the outer shell 1, sealing the connection between the shield 2031 and the outer shell 1, further enhancing the dustproof effect and preventing dust and moisture from entering the socket 101.

[0050] When the plug needs to be inserted, first rotate the baffle 203 to the open position. After inserting the plug, rotate the baffle 203 so that the anti-disconnection part 2032 rotates to the downward position. The plug's wire is led out from the U-shaped wire outlet groove 2034. The anti-disconnection part 2032 blocks the opening of the socket 101, which limits the plug and can effectively prevent the plug from coming out of the socket 101 due to accidental pulling or other situations during use, thus ensuring the stability of the plug connection.

[0051] The power port 102 on the outer casing 1 is used to connect to a power source, and the switch 103 is used to control the system's start and stop. The heat dissipation fins 104 increase the heat dissipation area, helping the system dissipate heat promptly during operation and maintain its normal operating temperature. The lifting pad 105 elevates the outer casing 1, preventing its lower surface from directly contacting the placement surface, reducing the impact of moisture and wear, and also facilitating airflow at the bottom for heat dissipation. The indicator light 106 uses different light colors or flashing patterns to indicate the system's operating status, such as normal operation or malfunction, allowing users to easily understand the system's status.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate and not limit the technical solutions of this utility model. Although this utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model without departing from the spirit and scope of this utility model. Any modifications or partial substitutions should be covered within the scope of the claims of this utility model.
