[0030] Example

[0031] like Figures 1-5As shown, this embodiment provides a proximity switch for a connector plate, specifically a novel device for signal feedback during connector plate earpiece connection in the biopharmaceutical industry. It includes: a connector plate 1, a plurality of proximity switches 2 installed inside the connector plate 1, and a plurality of earpieces 3 disposed on one side of each proximity switch 2. The connector plate 1 has a plurality of mounting bases 12 for connecting the earpieces 3. Each earpiece 3 is equipped with a sensing rod 31. When both ends of the earpiece 3 are connected to any two mounting bases 12, the sensing rod 31 is positioned directly opposite one of the proximity switches 2, enabling integrated installation of multiple proximity switches 2, thus improving the overall efficiency of the connector plate. The device is more compact and saves space. Multiple proximity switches 2 can work simultaneously, improving detection redundancy and reliability, making it suitable for complex application scenarios requiring multi-point detection. The sensing rod 31 facing the proximity switch 2 ensures accurate transmission of the sensing signal, thereby improving sensing sensitivity and accuracy. This ensures that the proximity switch 2 can accurately detect the presence or absence of the target object, reducing the possibility of misjudgment. One earpiece 3 requires only one proximity switch 2, greatly reducing costs. Furthermore, the earpiece 3 and the proximity switch 2 are not connected and have a certain distance between them, leaving sufficient operating space during installation to avoid collisions and ensure its service life.

[0032] The adapter plate 1 serves several purposes: connecting different pipelines; enabling connections between pipelines of different diameters, materials, or orientations, allowing the pipeline system to be laid out and extended according to design requirements; changing pipeline direction; allowing pipelines to change direction in space to avoid obstacles or meet specific process flows; distributing fluid; some adapter plates 1 have multiple interfaces, allowing one stream of fluid to be distributed to multiple different pipeline branches, achieving fluid diversion; and facilitating installation and maintenance; during the installation of the pipeline system, the adapter plate 1 can be installed and adjusted as an independent component, making it convenient for construction personnel and improving efficiency.

[0033] Meanwhile, the proximity switch 2 is used to detect whether the earpiece 3 of the adapter plate 1 has reached a specific position, and plays a role in detecting the connection status of the pipeline. During the production process, the process pipelines need to be converted and connected on the adapter plate 1. The proximity switch 2 can sense whether the conversion and connection of various process pipelines are in place, and thus give control commands to the PLC control device to determine whether the automatic control valve of the corresponding pipeline can be opened or closed, or to perform other operations.

[0034] In this embodiment, the two ends of the earpiece 3 are respectively mounted on the fixing base 12 of the adapter plate 1, and the sensing rod 31 is provided in the middle, which can ensure the stable installation of the earpiece 3. At the same time, the sensing rod 31 is located in the middle, which can keep its distance from the proximity switch 2 consistent, ensuring the consistency and accuracy of the sensing signal. The fixing base 12 can provide stable support for the earpiece 3, reducing vibration and displacement.

[0035] In this embodiment, a gap 32 is left between the sensing rod 31 and the proximity switch 2, that is, there is a certain distance between the two, which can prevent physical contact between the sensing rod 31 and the proximity switch 2, thereby avoiding wear or damage caused by contact. In addition, the existence of the gap 32 can reduce signal interference and ensure the stability and accuracy of the sensing signal.

[0036] In this embodiment, the proximity switch 2 is correspondingly disposed in the mounting hole 11 of the adapter plate 1, which facilitates the installation and fixation of the proximity switch 2, improves the stability and reliability of the installation, and the mounting hole 11 can provide precise positioning for the proximity switch 2, ensuring its stability during operation and reducing detection errors caused by position offset; installing the proximity switch 2 into the mounting hole 11 can also protect the precision instrument and greatly extend the service life of the adapter plate 1.

[0037] In this embodiment, the signal output line of the proximity switch 2 is located on the back of the adapter plate 1, that is, on the side opposite to the earpiece 3. This can avoid interference between the signal line and the sensing area, improve the stability of signal transmission, and the back wiring can make the entire device look neater, more beautiful and easier to maintain. The cable will not come into contact with the liquid medicine, which is hygienic, safe and easy to maintain and manage.

[0038] In this embodiment, the earpiece 3 is U-shaped. The U-shaped design can provide better support and protection for the sensing rod 31. At the same time, the U-shaped structure can increase the movement space of the sensing rod 31, enabling it to respond more flexibly to the approach of the target object.

[0039] In this embodiment, the various earpieces 3 do not interfere with each other, which can ensure that each earpiece 3 and its sensing rod 31 work independently, avoid mutual signal interference, improve the detection accuracy and reliability of the entire device, and is suitable for application scenarios that require multi-point independent detection.

[0040] In this embodiment, a water receiving tray 13 is provided at the lower part of the adapter plate 1. The water receiving tray 13 can collect any liquid that may drip, preventing liquid from entering the proximity switch 2 or other electronic components, thereby improving the waterproof performance and reliability of the device. It is particularly suitable for working environments with dampness or liquid dripping.

[0041] In this embodiment, the lowest point of the water receiving tray 13 is provided with a water outlet 14. More preferably, the interior of the water receiving tray 13 is inclined to ensure that the water can flow to the water outlet 14, which can easily drain the water in the water receiving tray 13, prevent excessive water accumulation from causing overflow or other problems, further improve the waterproof performance and reliability of the device, and ensure the long-term stable operation of the device in a humid environment.

[0042] In this embodiment, the proximity switch 2 and the mounting hole 11 are connected by a thread, which can provide a reliable fixing method, ensure the stability of the proximity switch 2 in the mounting hole 11, and the threaded connection is easy to install and remove, making it convenient for maintenance and replacement.

[0043] Of course, the two mounting bases 12 used to install the same earpiece 3 and the proximity switch 2 opposite to the sensing rod 31 on the earpiece 3 are all in a straight line, making disassembly and assembly convenient and the layout reasonable.

[0044] In addition, the sensing range of the proximity switch 2 is generally 2mm-5mm. The specific range can be selected according to the model of the proximity switch 2. Different proximity switches 2 have different sensing ranges. The gap 32 should be within this range, that is, it is necessary to ensure that the sensing rod 31 can quickly and accurately receive the signal and feed it back to the earpiece 3.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
