Description

Technical Field

[0001] This utility model belongs to the field of industrial sensor technology, and in particular relates to a fast interface for a highly interference-resistant industrial sensor. Background Technology

[0002] In the current era of rapid development in industrial automation and intelligent manufacturing, industrial sensors play an indispensable role in all aspects of industrial production. By accurately collecting key data such as temperature, pressure, and flow rate, they provide crucial information for monitoring and controlling production processes. The interface between industrial sensors and equipment, serving as a bridge for data transmission, directly impacts the stability and reliability of the entire industrial system.

[0003] When faced with strong electromagnetic interference, ordinary industrial sensor interfaces are unable to effectively block external electromagnetic signals from interfering with the transmitted data, which can easily cause signal distortion and data loss, leading to misjudgments by production equipment and causing production accidents or product quality problems. At the same time, existing interface connection methods usually rely on traditional forms such as screw fastening and plug-in connection. Screw fastening is cumbersome and consumes a lot of time and manpower. Although plug-in interfaces are relatively simple to operate, they lack a precise positioning structure, which can easily lead to deviations during connection, resulting in poor contact and poor connection stability. In the case of equipment vibration, the interface is prone to loosening, affecting signal transmission.

[0004] To address these issues, we provide a fast interface for highly interference-resistant industrial sensors. Utility Model Content

[0005] The purpose of this invention is to provide a fast interface for a highly interference-resistant industrial sensor. By combining a shielding component and a fast positioning mechanism, it solves the problem that the shielding design of existing industrial sensors is difficult to effectively block external electromagnetic signals from interfering with the transmitted data when facing strong electromagnetic interference. Traditional plug-in structures lack a precise positioning structure, which can easily lead to deviations and poor contact during the connection process.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a quick interface for a high-interference-resistance industrial sensor, comprising a plug and a socket. The plug has a shielding assembly on its surface. Quick positioning mechanisms are provided at both the front and rear ends of the plug. A sealing seat is fixedly connected to one side of the plug, and a connector is fixedly connected to the inner cavity of the sealing seat. The shielding assembly includes a shielding cover fitted onto the surface of the plug. Connecting posts are fixedly connected to the top and bottom of one side of the shielding cover. Connecting seats are fixedly connected to the top and bottom of the plug. The side of the connecting post away from the shielding cover extends into the inner cavity of the connecting seat. A connector is fixedly connected to one side of the connecting post. The first spring is fixedly connected to the connecting seat on one side. The shield and the plug form a resettable shield structure through the combination of the connecting post, the connecting seat and the first spring. When the plug and the socket are connected, as the socket contacts the shield and compresses the shield, the first spring pushes the shield to tightly wrap the connection part of the plug and the socket after reaching the predetermined position. Combined with the guiding and limiting functions of the slider and the slide groove, it ensures that the shield covers the connection area without gaps, which can effectively isolate external electromagnetic interference signals, greatly improve the stability of signal transmission in complex electromagnetic environments, and ensure the accuracy of data collected by industrial sensors.

[0008] The present invention is further configured such that the quick positioning mechanism includes a push block, the push block being disposed at the front end and rear end of the plug, one side of the push block penetrating into the inner cavity of the plug, a connecting plate being fixedly connected to one side of the push block, a locking block being fixedly connected to one side of the surface of the connecting plate, the side of the locking block away from the connecting plate penetrating into the outside of the plug, and a second spring being fixedly connected to both sides of the rear end of the connecting plate, one side of the second spring being fixedly connected to the inner wall of the plug. When the push block is pressed, the push block drives the connecting plate to move in the inner cavity of the plug, causing the locking block to retract into the plug. At this time, the plug is aligned with the socket and inserted. After the push block is released, the second spring, by its own elastic force, pushes the connecting plate and the locking block outward, and the locking block is engaged in the locking hole of the socket. Compared with traditional screw fastening and other connection methods, the connection time is greatly shortened.

[0009] The present invention is further configured such that sliding grooves are provided on both sides of the top and both sides of the bottom of the plug, and sliders that cooperate with the sliding grooves are fixedly connected to the top and bottom of the inner cavity of the shield. The sliding grooves and sliders cooperate with each other, and when the socket squeezes the shield, the sliders can slide smoothly along the plug axis in the sliding groove to ensure that the shield is always in the correct position.

[0010] The present invention is further configured such that the front and rear ends of the socket are provided with locking holes, the locking holes are adapted to the locking blocks, and when the plug is inserted into the socket, the locking blocks can accurately lock into the locking holes, effectively avoiding poor contact problems caused by connection deviation.

[0011] The present invention is further configured such that a mounting plate is fixedly connected to one side of the socket, and positioning holes are provided at the four corners of the surface of the mounting plate. The mounting plate and positioning holes enable the socket to be quickly and conveniently fixedly installed in the designated position of the industrial equipment without complicated installation tools and operating procedures, making the installation process simple and efficient.

[0012] The present invention is further configured such that a connecting block is fixedly connected to the other side of the plug, and a connecting wire is fixedly connected to one side of the connecting block. The connecting block provides a stable installation base for the connecting wire. It is fixedly connected to the plug and can withstand external forces such as pulling and bending that the connecting wire is subjected to during use, thus protecting the reliability of the connection point between the connecting wire and the plug.

[0013] The present invention is further configured such that a socket is provided on one side of the socket, and a sealing ring is fixedly connected to the inner wall of the socket. The sealing ring enhances the sealing and protection performance of the interface. When the plug is inserted into the socket, the sealing ring is squeezed and deformed, tightly fitting the surface of the plug, which can effectively prevent external impurities such as water vapor, dust, and oil from entering the interface.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model achieves effective protection through a resettable and movable shielding cover. During the insertion process, the socket contacts the shielding cover and applies pressure to compress it. When it reaches the predetermined position, the first spring pushes the shielding cover to fit tightly against the plug, and at the same time completely wraps the connection between the socket and the plug, thereby providing all-round shielding protection for this part. It can effectively shield external electromagnetic interference. The shielding cover can isolate interference signals, greatly improving the stability and accuracy of signal transmission in complex electromagnetic environments, and providing reliable data protection for industrial production.

[0016] 2. This utility model achieves rapid and accurate connection between the plug and socket through a quick positioning mechanism. The reset force provided by the second spring ensures stable engagement of the locking block and prevents loosening of the connection. At the same time, the guide design of the plug and socket can guide the plug to be accurately inserted into the socket, reduce connection deviation, significantly shorten connection time, improve the installation and replacement efficiency of industrial sensors, reduce equipment downtime, and improve industrial production efficiency.

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figure 1-6 This utility model is a quick interface for a high-interference-resistant industrial sensor, including a plug 1 and a socket 2. The surface of the plug 1 is provided with a shielding component 3. The front end and the rear end of the plug 1 are provided with quick positioning mechanisms 4. A sealing seat 5 is fixedly connected to one side of the plug 1. A connector 6 is fixedly connected to the inner cavity of the sealing seat 5. The shielding component 3 includes a shielding cover 301, which is sleeved on the surface of the plug 1. A connecting post 302 is fixedly connected to the top and bottom of one side of the shielding cover 301. A connecting seat 303 is fixedly connected to the top and bottom of the plug 1. The side of the connecting post 302 away from the shielding cover 301 extends into the inner cavity of the connecting seat 303. A first spring 304 is fixedly connected to one side of the connecting post 302. One side of the first spring 304 is fixedly connected to the connecting seat 303.

[0028] Specifically, the shielding cover 301 and the plug 1 form a resettable shielding structure through the combination of the connecting post 302, the connecting seat 303, and the first spring 304. When the plug 1 is connected to the socket 2, as the socket 2 contacts and compresses the shielding cover 301, the first spring 304 pushes the shielding cover 301 to tightly wrap the connection part of the plug 1 and the socket 2 after reaching the predetermined position. Combined with the guiding and limiting functions of the slider 8 and the slide groove 7, it ensures that the shielding cover 301 covers the connection area without gaps, which can effectively isolate external electromagnetic interference signals, greatly improve the stability of signal transmission in complex electromagnetic environments, and ensure the accuracy of data collected by industrial sensors.

[0029] Example 2

[0030] Please see Figure 1-6 Based on Embodiment 1, the quick positioning mechanism 4 includes a push block 401, which is disposed at the front and rear ends of the plug 1. One side of the push block 401 extends into the inner cavity of the plug 1. A connecting plate 402 is fixedly connected to one side of the push block 401. A locking block 403 is fixedly connected to one side of the surface of the connecting plate 402. The side of the locking block 403 away from the connecting plate 402 extends into the outside of the plug 1. Second springs 404 are fixedly connected to both sides of the rear end of the connecting plate 402. One side of the second spring 404 is fixedly connected to the inner wall of the plug 1. The top of the plug 1... The two sides and the bottom of the plug 2 are provided with sliding grooves 7. The top and bottom of the inner cavity of the shielding cover 301 are fixedly connected with sliders 8 that cooperate with the sliding grooves 7. The front and rear ends of the socket 2 are provided with locking holes 9, which are adapted to the locking block 403. The side of the socket 2 is fixedly connected with a mounting plate 10. The four corners of the surface of the mounting plate 10 are provided with positioning holes 11. The other side of the plug 1 is fixedly connected with a connecting block 12. The side of the connecting block 12 is fixedly connected with a connecting wire 13. The side of the socket 2 is provided with a socket hole. The inner wall of the socket hole is fixedly connected with a sealing ring.

[0031] Specifically: When the button 401 is pressed, the button 401 moves the connecting plate 402 within the inner cavity of the plug 1, causing the locking block 403 to retract into the plug 1. At this time, the plug 1 is aligned with the socket 2 and inserted. After releasing the button 401, the second spring 404, using its own elastic force, pushes the connecting plate 402 and the locking block 403 outward. The locking block 403 then engages in the locking hole 9 of the socket 2. Compared to traditional screw fastening and other connection methods, this significantly shortens the connection time. The sliding groove 7 and the slider 8 cooperate with each other. When the socket 2 presses against the shielding cover 301, the slider 8 can slide smoothly along the axial direction of the plug 1 within the sliding groove 7, ensuring that the shielding cover 301 is always in the correct position. When the plug 1 is inserted into the socket 2, the locking block 403 can accurately engage in the locking hole 9. The mounting plate 10 and positioning holes 11 effectively avoid poor contact caused by connection deviation. The socket 2 can be quickly and conveniently fixed in the designated position of the industrial equipment without complicated installation tools and operating procedures. The installation process is simple and efficient. The connecting block 12 provides a stable installation base for the connecting wire 13. It is fixedly connected to the plug 1 and can withstand the external forces such as pulling and bending that the connecting wire 13 is subjected to during use, protecting the reliability of the connection point between the connecting wire 13 and the plug 1. The sealing ring enhances the sealing and protection performance of the interface. When the plug 1 is inserted into the socket 2, the sealing ring is squeezed and deformed, tightly fitting the surface of the plug 1, which can effectively prevent external impurities such as water vapor, dust, and oil from entering the interface.

[0032] The working principle of this utility model is as follows: The operator connects the plug 1 and the socket 2, aligning the plug 1 with the socket 2's insertion hole. As the plug 1 is inserted into the socket 2, the squeezing force applied by the socket 2 to the plug 1 acts on the quick positioning mechanism 4. When the push block 401 is squeezed, it drives the connecting plate 402 to move within the plug 1's cavity, thereby causing the locking block 403 on one side of the connecting plate 402 to retract into the plug 1. When the plug 1 is further inserted to the predetermined position, the squeezing force is eliminated, and the second spring 404 pushes the connecting plate 402 and the locking block 403 outward by its own elastic force. The locking block 403 engages in the pre-drilled locking holes 9 at the front and rear ends of the socket 2, completing the quick positioning and connection of the plug 1 and the socket 2.

[0033] During the connection process between plug 1 and socket 2, socket 2 simultaneously contacts and applies pressure to the shielding cover 301 on the surface of plug 1. Since the shielding cover 301 is connected to plug 1 through connecting post 302, connecting seat 303 and first spring 304, the first spring 304 is compressed under pressure, and the shielding cover 301 moves towards plug 1. When plug 1 and socket 2 reach the predetermined connection position, the first spring 304 pushes the shielding cover 301 to tightly wrap the connection part of plug 1 and socket 2, forming a complete electromagnetic shielding space.

[0034] When it is necessary to disassemble the industrial sensor interface, the operator presses the front and rear buttons 401 of the plug 1. The buttons 401 drive the connecting plate 402 to move inside the plug 1, causing the locking block 403 to retract into the plug 1 and release the locking state with the locking hole 9 of the socket 2. The plug 1 can then be easily pulled out of the socket 2 to complete the disassembly operation. The entire disassembly process is simple and convenient for staff to perform maintenance work such as inspection and replacement of industrial sensors.
