Description

Technical Field

[0001] The present disclosure relates to optoelectronic connector assemblies. Background Art

[0002] Sensors can be used to measure various parameters to be measured, such as temperature, pressure, humidity, etc. Some types of sensors convert the state of the parameter to be measured into a sensor signal, and a sensor demodulation device demodulates the sensor signal to obtain the measurement value.

[0003] Before the sensor demodulation device can perform demodulation, it needs to know the parameters of each sensor, such as identifying the sensor model and serial number to enable the corresponding demodulation algorithm, or obtaining the calibration parameters of each individual sensor to obtain more accurate measurements. For this reason, currently commonly used sensors are usually accompanied by a label containing the sensor parameters. Before inserting the sensor into the sensor demodulation device, the information on the sensor label needs to be manually input into the demodulation device so that it can know the sensor parameters. This manual reading of information is cumbersome, inefficient, and prone to errors. Utility Model Content

Existing information can be erased and reprogrammed on a computer or a dedicated device, and the application is flexible.

[0039] The printed circuit board with integrated information storage chip is set in the needle seat connector. After the needle seat connector is inserted into the flange connector, the remote device information connected to the needle seat connector, such as sensor information or host information, is loaded onto the host connected to the flange connector, so that the remote device can be plug-and-play without manual input or code scanning to load the remote device information, thus reducing the operation time. For equipment manufacturers, the identity information of the remote device can be written into the information storage chip, which can achieve anti-counterfeiting and traceability.

[0040] The needle seat connector includes a needle seat end ceramic ferrule 2, which is arranged in the optical hole 11 and passes through the needle seat connector body 1, and can be arranged near the center of the needle seat connector body 1. The needle seat end ceramic ferrule tail end 22 located at the first end 13 of the needle seat connector body is connected to an optical cable (not shown in the figure), and the needle seat end ceramic ferrule 2 is a structure of a ceramic tube covering an optical fiber, and is optically connected to the optical cable through the optical fiber. The needle seat end ceramic ferrule head end 21 located at the second end 14 of the needle seat connector body is installed with a ceramic socket 5, and the needle seat end ceramic ferrule head end 21 is inserted into a part of the length of the ceramic socket 5. When the needle seat connector is plugged into the flange connector, the flange end ceramic ferrule head end 81 is plugged into the remaining length of the ceramic socket 5 and docked with the needle seat end ceramic ferrule head end 21. The ceramic socket 5 is a fragile item and is easy to break. Compared with setting the ceramic socket on the flange connector, the fragile and vulnerable parts are placed at the consumable end, which reduces the risk of damage to the device end connector and effectively extends the service life.

[0041] The ceramic socket 5 can be a cylindrical structure such as a C-shaped cylinder. The cylindrical ceramic socket 5 can clamp the needle seat end ceramic ferrule 2 and the flange end ceramic ferrule 8, thereby ensuring that the optical fiber in the needle seat end ceramic ferrule 2 and the flange end ceramic ferrule 8 is coaxial.

Such an arrangement can reduce the volume of the flange connector and the needle holder connector, and accommodate multiple cables and optical cables in a smaller volume.

[0044] The electrical socket 71 corresponding to the metal pin electrically connected to the power supply pin of the information storage chip can be used for grounding and 3-4VDC connection respectively. The electrical socket corresponding to the metal pin electrically connected to the programming pin of the information storage chip can be used to connect to the input port of the external host. When the needle seat connector is inserted into the flange connector, the host can read the information in the information storage chip. The inner wall of the annular boss of the flange connector can be set to an asymmetric shape, and the inner side wall of the corresponding annular groove 12 of the needle seat connector can be set to a matching asymmetric shape, such as a horseshoe shape, to indicate the plugging direction, to ensure that the metal pin electrically connected to the power supply pin of the information storage chip is plugged into the electrical socket of the external power supply, and to ensure that the metal pin electrically connected to the programming pin of the information storage chip is plugged into the electrical socket of the input port of the external host.

[0045] When in use, the optical cable connected to the tail end of the ceramic ferrule at the needle seat end can be connected to the optical cable of the sensor or medical device, the optical cable connected to the tail end of the ceramic ferrule at the flange end can be connected to the optical cable of the demodulation device, and the cable electrically connected to the electrical jack of the flange connector can be connected to the input port of the external host and the power supply respectively.
