Technical Field
[0001] This utility model relates to the field of plastic sensor technology, specifically to a plastic sensor that is easy to weld. Background Technology
[0002] A plastic sensor is a sensor whose structure is partially or entirely made of plastic material. With the continuous development of materials science and sensor technology, plastic sensors have been increasingly widely used in various fields due to their unique advantages. Classified by the physical quantity they sense, they include temperature sensors, humidity sensors, pressure sensors, and light sensors. For example, plastic temperature sensors measure temperature by utilizing the principle that the thermal properties of plastic materials change with temperature; plastic pressure sensors sense pressure by detecting the deformation of the plastic structure under pressure. Classified by working principle, they include capacitive sensors, resistive sensors, and piezoelectric sensors. For instance, capacitive plastic sensors measure based on the change in capacitance caused by the plastic medium under the action of the measured quantity, while resistive plastic sensors work by utilizing the characteristic that the resistance of the plastic material changes with the measured quantity.
[0003] Existing plastic sensors, while capable of environmental detection, suffer from unstable output signals and reduced lifespan due to vibrations during use, causing internal movement or detachment. Therefore, we propose a weldable plastic sensor to address these issues. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-4 This utility model provides a technical solution: a plastic sensor that is easy to weld, including a sensor assembly 2, which is used to detect the environment; a placement assembly 1, which is disposed on the bottom surface of the sensor assembly 2 and is used to support and limit the sensor assembly 2; and a fixing assembly 3, which is disposed on the top surface of the placement assembly 1 and is used to limit and fix the sensor assembly 2.
[0023] When welding a plastic sensor is required, first place the placement component 1 in the preset position, and then place the sensor component 2 in the inner cavity of the placement component 1. Since the top surface of the placement component 1 is fixedly connected to the fixing component 3, the placement component 1 can provide support for the sensor component 2 and the fixing component 3, thereby enabling the placement component 1 and the fixing component 3 to be welded, so as to limit and fix the sensor component 2, thereby improving the stability of the sensor component 2.
[0024] See Figure 1 , Figure 2The placement component 1 includes a fixing plate 11, a placement plate 12 is provided on the top surface of the fixing plate 11, through holes 13 are provided near the four corners of the top surface of the fixing plate 11, and multiple insertion posts 14 are provided on the top surface of the fixing plate 11. The multiple insertion posts 14 are distributed in a rectangular array. A mounting groove 15 is provided in the center of the top surface of the placement plate 12. The mounting groove 15 is connected to the sensor component 2. Chamfers 17 are provided around the top surface of the placement plate 12 to facilitate welding. Clamping grooves 16 are provided on the lower part of both sides of the placement plate 12 to fix the external clamps during the welding process.
[0025] The fixing plate 11 in the placement component 1 can be placed in a preset position and also provides an installation base for the placement plate 12. Since the top surface of the fixing plate 11 has through holes 13 near the four corners, workers can fix the fixing plate 11 through the through holes 13, thereby fixing the placement plate 12 and improving the stability of the placement plate 12. Since the top surface of the fixing plate 11 is fixedly connected to multiple posts 14 arranged in a rectangular array, the fixing plate 11 can be connected to the fixing component 3, thus providing support for the fixing component 3 and increasing connection stability. The top surface of the placement plate 12 has an installation groove 1 at its center. 5. The mounting groove 15 is connected to the sensor assembly 2, thereby limiting the sensor assembly 2 and allowing the placement plate 12 to support the sensor assembly 2, so that the sensor assembly 2 can be fixedly connected to the inner cavity of the mounting groove 15. Since the top surface of the placement plate 12 is chamfered around all four sides, the welding area can be increased, thereby reducing stress concentration and enhancing mechanical strength. Since the lower part of both sides of the placement plate 12 is provided with clamping grooves 16, the placement plate 12 can be clamped by external clamps, thereby fixing the placement plate 12 during the welding process, and ensuring accurate alignment during the welding process, thus ensuring the accuracy and consistency of the welding position and improving the welding quality.
[0026] See Figure 1 , Figure 3 The sensor assembly 2 includes a support plate 21, which has an inner cavity of mounting groove 15. A limiting groove 22 is opened on the top surface of the support plate 21, and a sensor body 23 is provided in the inner cavity of the limiting groove 22. L-shaped brackets 24 are provided on the top surface of the support plate 21 near the four corners.
[0027] The support plate 21 in the sensor assembly 2 can be fixedly connected to the inner cavity of the mounting groove 15 and can also provide a foundation for opening the limiting groove 22. Since the sensor body 23 is connected to the inner cavity of the limiting groove 22, and L-shaped brackets 24 are fixedly connected to the top surface of the support plate 21 near the four corners, the support plate 21 can provide support for the L-shaped brackets 24. The L-shaped brackets 24 can then limit the sensor body 23 and fix it in place, so as to prevent the sensor body 23 from shaking in the inner cavity of the limiting groove 22 and improve the stability of the sensor body 23 during use.
[0028] See Figure 1 , Figure 4 The fixing component 3 includes a locking cover 31, which is disposed on the top surface of the placement plate 12. The bottom surface of the locking cover 31 has a slot 32, and multiple slots 32 are distributed in a rectangular array. The top surface of the inner cavity of the locking cover 31 is provided with a pressure plate 33, and a sealing plate 34 is provided at the lower position of the inner cavity of the locking cover 31. The sealing plate 34 is used to increase the sealing between the locking cover 31 and the placement plate 12.
[0029] The engaging cover 31 in the fixing component 3 can be fixedly connected to the top surface of the placement plate 12 and also provide a base for the slot 32. Since multiple slots 32 are provided and arranged in a rectangular array, and the slots 32 are connected to the inserts 14, the inserts 14 can be inserted into the inner cavity of the slots 32. This allows the bottom surface of the engaging cover 31 to fit against the top surface of the placement plate 12, facilitating welding. Since a pressure plate 33 is fixedly connected to the top surface of the inner cavity of the engaging cover 31, and the inner cavity of the engaging cover 31 is located at the bottom... A sealing plate 34 is fixedly connected to the position, so that the pressure plate 33 can be pressed on the top of the sensor body 23 while the locking cover 31 is being welded, thereby preventing the sensor body 23 from falling off during use and thus improving its service life. Then, through the sealing plate 34, the sealing plate 34 can be inserted into the mounting groove 15, thereby increasing the sealing between the locking cover 31 and the placement plate 12, so as to protect the internal electronic components from damage, extend the service life of the sensor, and ensure its long-term stable operation.
[0030] When welding a plastic sensor is required during operation, the placement component 1 is first placed in a preset position, and then the sensor component 2 is placed inside the placement component 1. Since the top surface of the placement component 1 is fixedly connected to the fixing component 3, the placement component 1 can provide support for the sensor component 2 and the fixing component 3, thereby enabling the placement component 1 and the fixing component 3 to be welded, so as to limit and fix the sensor component 2, thereby improving the stability of the sensor component 2.
[0031] The fixing plate 11 in the placement component 1 can be placed in a preset position and also provides an installation base for the placement plate 12. Since the top surface of the fixing plate 11 has through holes 13 near the four corners, workers can fix the fixing plate 11 through the through holes 13, thereby fixing the placement plate 12 and improving the stability of the placement plate 12. Since the top surface of the fixing plate 11 is fixedly connected to multiple posts 14 arranged in a rectangular array, the fixing plate 11 can be connected to the fixing component 3, thus providing support for the fixing component 3 and increasing connection stability. The top surface of the placement plate 12 has an installation groove 1 at its center. 5. The mounting groove 15 is connected to the sensor assembly 2, thereby limiting the sensor assembly 2 and allowing the placement plate 12 to support the sensor assembly 2, so that the sensor assembly 2 can be fixedly connected to the inner cavity of the mounting groove 15. Since the top surface of the placement plate 12 is chamfered around all four sides, the welding area can be increased, thereby reducing stress concentration and enhancing mechanical strength. Since the lower part of both sides of the placement plate 12 is provided with clamping grooves 16, the placement plate 12 can be clamped by external clamps, thereby fixing the placement plate 12 during the welding process, and ensuring accurate alignment during the welding process, thus ensuring the accuracy and consistency of the welding position and improving the welding quality.
[0032] The support plate 21 in the sensor assembly 2 can be fixedly connected to the inner cavity of the mounting groove 15 and can also provide a foundation for opening the limiting groove 22. Since the sensor body 23 is connected to the inner cavity of the limiting groove 22, and L-shaped brackets 24 are fixedly connected to the top surface of the support plate 21 near the four corners, the support plate 21 can provide support for the L-shaped brackets 24. The L-shaped brackets 24 can then limit the sensor body 23 and fix it in place, so as to prevent the sensor body 23 from shaking in the inner cavity of the limiting groove 22 and improve the stability of the sensor body 23 during use.
[0033] The engaging cover 31 in the fixing component 3 can be fixedly connected to the top surface of the placement plate 12 and also provide a base for the slot 32. Since multiple slots 32 are provided and arranged in a rectangular array, and the slots 32 are connected to the inserts 14, the inserts 14 can be inserted into the inner cavity of the slots 32. This allows the bottom surface of the engaging cover 31 to fit against the top surface of the placement plate 12, facilitating welding. Since a pressure plate 33 is fixedly connected to the top surface of the inner cavity of the engaging cover 31, and the inner cavity of the engaging cover 31 is located at the bottom... A sealing plate 34 is fixedly connected to the position, so that the pressure plate 33 can be pressed on the top of the sensor body 23 while the locking cover 31 is being welded, thereby preventing the sensor body 23 from falling off during use and thus improving its service life. Then, through the sealing plate 34, the sealing plate 34 can be inserted into the mounting groove 15, thereby increasing the sealing between the locking cover 31 and the placement plate 12, so as to protect the internal electronic components from damage, extend the service life of the sensor, and ensure its long-term stable operation.
[0034] In summary, this device enables the plastic sensor to detect the environment while preventing it from shaking or falling off during use, thus ensuring a stable output signal and extending its service life.
