DETAILED DESCRIPTION

[0034] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments cited do not limit the present invention. In this embodiment, it should be understood that the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention.

[0035] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to the other element and integrated therewith, or there may be an intermediate element. The terms "mounted," "one end," "the other end," and similar expressions used in this utility model are for illustrative purposes only.

[0036] This embodiment provides a cable end connector, such as Figures 1 to 5 As shown, it includes a first connector 1 and a second connector 2.

One end of the first connector 1 and one end of the second connector 2 can be plugged into each other, and the other ends of the first connector 1 and the second connector 2 are both used to connect cables.

[0037] The first connector 1 is further provided with an optical signal detection module 5 , which is used to detect the signal strength of the optical fiber 4 in real time and feed back the signal strength of the optical fiber 4 to the host computer 9 .

[0038] The utility model sets an optical signal detection module 5 on the first connector 1, and the optical signal detection module 5 can feed back the signal strength of the optical fiber 4 detected by it in real time to the host computer 9, so that the connection status of the first connector 1 and the second connector 2 can be judged by checking the real-time signal strength of the optical fiber 4, thereby solving the problem that the existing cable connectors only realize the cable connection function but cannot monitor the connection status of the connectors.

[0039] In addition, by checking the real-time signal strength of optical fiber 4, the operating status of the cable can also be partially reflected, which makes it easier for staff to conduct daily monitoring and promptly detect cable faults, thereby improving the intelligence of connectors and cables.

[0040] It should be noted that in actual use, the male head of the connector is usually detachable and movable, while the female head is generally fixed in a certain position. It is preferred to use the first connector 1 as the female head and the second connector 2 as the male head. This can avoid damage to the detection module during movement after multiple disassembly.

The frequency detection module 503 is connected to the first output end signal of the signal stabilizer 502, and is used to output the signal strength detection value of the optical fiber 4. The two ends of the optical modulator 504 are respectively connected to the second output end of the signal stabilizer 502 and the optical fiber 4; the frequency detection module 503 is also used to communicate with the host computer 9. In this embodiment, the optical fiber 4 emits an optical signal of a certain wavelength, the photodiode 501 converts the optical signal into an electrical signal, the signal stabilizer 502 maintains the stability of the output voltage through the negative feedback principle, and the frequency detection module 503 detects the wave frequency of the electrical signal output from the first output end of the signal stabilizer 502 in real time to obtain the intensity value of the communication signal of the optical fiber 4; the electrical signal output from the second output end of the signal stabilizer 502 is converted into an optical signal by the optical modulator 504 and transmitted to the optical fiber 4 and then re-transmitted along the optical fiber 4; the optical signal emitted from the optical fiber 4 is processed by the photodiode 501, the signal stabilizer 502, and the frequency detection module 503 to obtain the optical fiber 4 signal strength detection value, and the optical fiber 4 signal strength detection value is sent to the host computer 9 through the frequency detection module 503.

The communication integration module 8 is also used to communicate with a host computer 9, and processes the detection signal output by the optical signal detection module 5 and transmits it to the host computer 9. By providing the communication integration module 8 in this embodiment, when the cable is provided with multiple optical fibers 4, each optical signal detection module 5 is separately connected to the communication integration module 8 for signal communication, thereby simplifying the internal circuit configuration and improving the integration of the connector.

In this embodiment, the voltage divider 6011 reduces the higher voltage, the RMS-DC conversion circuit 6012 rectifies and averages the AC voltage and converts it into a DC current. The RMS-DC conversion circuit 6012 converts the AC signal into a DC signal and sends it to the A / D converter 6013. The A / D converter 6013 measures the voltage value of the DC signal and sends it to the host computer 9. This embodiment is suitable for monitoring high and low voltage cables.

The A / D converter 6013 is also used for communication with the host computer 9. In this embodiment, the current signal can be converted into a voltage signal by the shunt resistor 6021, which is then amplified to an appropriate voltage value by the gain switching circuit 6022. The current value is then output by the A / D converter 6013 and sent to the host computer 9.

[0047] Furthermore, in an embodiment for a three-phase power cable, the first connector 1 is further provided with a communication integration module 8. There are three electrical conductors 3, each of which is provided with a corresponding current detection unit 602. Each current detection unit 602 is separately signal-connected to the communication integration module 8. The communication integration module 8 is also configured to communicate with a host computer 9, processing the detection signal received from the power detection module 6 and transmitting it to the host computer 9. Specifically, the analog signal is converted into a digital signal and then transmitted to the host computer 9. This embodiment can simultaneously detect the current values ​​of the three conductive wires in real time. By providing the communication integration module 8 and separately signal-connecting each current detection unit 602 to the communication integration module 8, the internal wiring configuration can be simplified and the connector's integration level can be improved.

In actual use, the first connector 1 and the second connector 2 are usually fastened by a threaded connection after being plugged in. In this embodiment, the tension detection module 7 is provided at the connection between the first connector 1 and the second connector 2. The tension detection module 7 monitors the change in the preload force at the connection in real time, thereby determining the tightness of the connection between the first connector 1 and the second connector 2.

[0049] Further, such as Figure 9 As shown, the first connector 1 is further provided with a communication integration module 8, which is signal-connected to the tension detection module 7, the optical signal detection module 5, and the power detection module 6, respectively.
