Figure 3 , Figure 4 The three-dimensional exploded schematic diagrams of an embodiment of the optical sensor communication terminal of the utility model at different angles are shown respectively. The optical sensor communication terminal 100 includes a housing component 110 , a vibration component 120 , and an electrical component 130 .

[0045] The housing assembly 110 includes an intermediate housing 113, a first housing 111, and a second housing 112. The intermediate housing 113 is sandwiched between the first housing 111 and the second housing 112. The intermediate housing 113 has a first surface S1 and a second surface S2 opposite to each other. An optical cable cavity A1 is enclosed between the first surface S1 of the intermediate housing 113 and the first housing 111. An electrical cavity A2 is enclosed between the second surface S2 of the intermediate housing 113 and the second housing 112. The optical cable 200 sandwiched between the intermediate housing 113 and the first housing 111 is arranged through the optical cable cavity A1.

[0046] The vibration assembly 120 is disposed in the optical cable cavity A1, and is used to abut against the optical cable 200 to apply vibration to the optical cable 200. The electrical assembly 130 is disposed in the electrical cavity A2 and is electrically connected to the vibration assembly 120, and the electrical assembly 130 can be connected to external devices for communication.

[0047] According to the optical sensing communication terminal 100 of the embodiment of the utility model, it includes a housing component 110, a vibration component 120 and an electrical component 130. The housing component 110 includes an intermediate housing 113, a first housing 111 and a second housing 112. The first surface S1 of the intermediate housing 113 and the first housing 111 enclose an optical cable cavity A1. The first housing 111 and the intermediate housing 113 can clamp the optical cable 200 together. The optical cable 200 clamped between the intermediate housing 113 and the first housing 111 passes through the optical cable cavity A1. The vibration component 120 is arranged in the optical cable cavity A1 and abuts against the optical cable 200 to apply vibration to the optical cable 200. The electrical component 130 is electrically connected to the vibration component 120 and can be connected to an external device for communication. When the optical sensing communication terminal 100 is in a normal working state, the electrical component 130 obtains the communication signal to be transmitted from the external device, and drives the vibration component 120 to apply vibration to the optical cable 200 according to the communication signal with a corresponding vibration signal. The base station 300 connected to the optical cable 200 can emit a laser signal. The vibration of the optical cable 200 by the vibration component 120 enables the optical signal in the optical cable 200 to generate reverse photons corresponding to the vibration signal, that is, a reflected light signal. The base station 300 collects the reflected light signal and can analyze it to obtain the corresponding vibration signal and communication signal, thereby realizing the transmission and demodulation of the communication signal and completing the optical sensing communication function.

[0048] The optical sensing communication terminal 100 of the embodiment of the utility model is installed on the optical cable 200 by clamping the first housing 111 and the intermediate housing 113, and realizes the coupling of the signal to the optical cable 200 through the cooperation of the electrical component 130 and the vibration component 120. The process of accessing the optical cable 200 does not require the optical cable 200 to be disconnected and connected, which improves the convenience of the optical sensing communication terminal 100 accessing the optical cable 200 and reduces the damage to the optical cable 200 during the access process. In addition, the vibration component 120 is arranged in the optical cable cavity A1, and the electrical component 130 is arranged in the electrical cavity A2. The components in the optical sensing communication terminal 100 are arranged in modules, which reduces the mutual influence of the sealing between the optical cable cavity A1 and the electrical cavity A2, thereby blocking the water vapor in the optical cable cavity A1 from flowing to the electrical cavity A2 to a certain extent, which is convenient for improving the overall sealing of the optical sensing communication terminal 100, and also reduces the influence of the water vapor in the optical sensing communication terminal 100 on the electrical component 130, and improves the waterproof performance of the optical sensing communication terminal 100.

[0050] In the optical cable cavity A1, the area corresponding to the vibration component 120 requires a larger accommodation space, while other areas do not require a larger accommodation space. In the above embodiment, the outer surface of the first shell 111 has a protrusion 1111, and the bottom of the first groove 1112 opposite to the first surface S1 is provided with a second groove 1113 at the protrusion 1111. The second groove 1113 forms a deeper accommodation space through the protrusion 1111, thereby meeting the accommodation requirements for the vibration component 120, while other areas of the first groove 1112 are relatively shallow, so that the optical sensing communication terminal 100 can be more miniaturized while meeting the functional component accommodation space requirements.

[0051] In some embodiments, the vibration assembly 120 includes a connection seat 121, a clamp 122, and a vibration member 123.

[0052] In this embodiment, the clamp 122 clamps the optical cable 200 and connects it between the clamp 122 and the connecting seat 121. The vibration of the vibrator 123 can be transmitted to the optical cable 200 through the connecting seat 121, thereby improving the installation stability of the vibration assembly 120 and the stability of vibration transduction.

[0053] In some embodiments, the first surface S1 of the intermediate housing 113 is provided with a connecting portion 1131, and the connecting portions 1131 are distributed on opposite sides of the vibration assembly 120 along the extension direction of the optical cable 200. In some embodiments, the optical sensing communication terminal 100 further includes a clamping member 140. The clamping member 140 is detachably connected to the connecting portion 1131, and can clamp the optical cable 200 together with the connecting portion 1131.

[0054] By providing the clamping member 140 and the connecting portion 1131 , the portion of the optical cable 200 inserted into the optical cable cavity A1 can be fixed to avoid unnecessary shaking of the portion of the optical cable 200 , thereby ensuring the accuracy of signal transmission when vibration is applied to the optical cable 200 .

[0055] In some embodiments, the optical cable 200 sandwiched between the intermediate housing 113 and the first housing 111 extends along the first direction X. The first surface S1 of the intermediate housing 113 is provided with a first sealing groove 1132 for accommodating a first sealing member. The first sealing groove 1132 is located at opposite sides of the optical cable cavity A1 along the second direction Y. The second direction Y is perpendicular to the first direction X.

[0056] When the intermediate housing 113 is connected to the first housing 111 , a first sealing member is disposed in the first sealing groove 1132 , and the first sealing member is clamped between the intermediate housing 113 and the first housing 111 , which can further improve the sealing performance of the optical cable cavity A1 after installation.
