Description

Technical Field

[0001] This utility model relates to the field of temperature sensor technology, specifically a spring-loaded automotive coolant NTC temperature sensor detection device. Background Technology

[0002] The growth of the temperature sensor industry in recent years has been primarily driven by the increasing demand for temperature sensors in the automotive sector. The expanding automotive and industrial manufacturing industries, in particular, have generated enormous demand for temperature sensors.

[0003] Furthermore, the "localization" strategies of major international auto parts manufacturers in recent years have driven domestic auto parts suppliers to optimize and innovate their products, bringing new development momentum and opportunities for domestic substitution. As a supporting industry in the automotive supply chain, automotive sensors are crucial for improving automobile manufacturing levels, and the automotive electronic sensor industry has a promising future of rapid development.

[0004] Existing automotive coolant NTC temperature sensor detection devices typically use a large number of screws for installation. While this method is relatively simple in structure, it is inconvenient to operate and requires tools. If too much force is applied when removing or installing the screws, the screw holes can be easily damaged, resulting in stripped threads. To address this issue, we designed a snap ring mounting type automotive coolant NTC temperature sensor detection device. Utility Model Content

[0005] The purpose of this invention is to provide a snap ring mounted automotive coolant NTC temperature sensor detection device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides a snap ring mounted automotive coolant NTC temperature sensor detection device, including a connector plastic shell and a temperature sensing component disposed at the bottom of the connector plastic shell. A mounting base is sleeved on the connector plastic shell, and both the connector plastic shell and the temperature sensing component are located inside the mounting base. A snap ring body is movably inserted into the mounting base, and the snap ring body abuts against the outside of the connector plastic shell.

[0007] Furthermore, a limiting groove is provided on the mounting base, the limiting groove is connected to the inside of the mounting base, and the main body of the retaining ring is movably inserted into the limiting groove.

[0008] Furthermore, a lead screw is threaded into one side of the snap ring body, a pusher is fixedly installed at one end of the lead screw, and a torsion block is provided at the other end of the snap ring body, the torsion block engaging with the outer surface of the snap ring body.

[0009] Furthermore, the twist block is provided with anti-slip texture.

[0010] Furthermore, both ends of the retaining ring body are integrally formed with protruding edges, which are located outside the limiting groove.

[0011] Furthermore, the temperature sensor includes a terminal that is inserted into the bottom of the connector's plastic housing. An NTC thermistor is disposed on the terminal. A brass outer shell is disposed at the bottom of the connector's plastic housing. The terminal and the NTC thermistor are located inside the brass outer shell. An outer sealing ring is also fitted onto the terminal. A gasket is also fitted at the connection between the connector's plastic housing and the brass outer shell. A thermally conductive material is disposed inside the brass outer shell and is connected to the NTC thermistor.

[0012] Furthermore, a glass shell is provided on the terminal, and the NTC thermistor is disposed on the terminal through the glass shell.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: Since the snap ring body has a certain elasticity, both ends of the snap ring body can be bent to deform it, and then the snap ring body can be movably inserted into the limiting groove. Then, the snap ring body can be released to restore its shape and snap onto the connector plastic shell, thus facilitating the installation of the connector plastic shell. Disassembly can be performed according to the above principle. This temperature sensor has the advantages of fast detection speed, stable operation, easy installation, strong anti-interference ability, high accuracy, and strong waterproof ability.

[0014] Compared with the prior art, the beneficial effects of this utility model are: by rotating the torsion block, the torsion block can drive the lead screw and the pusher to rotate and push one side of the snap ring body, so that the two ends of the snap ring body are far apart, which makes it easier for personnel to pry the snap ring body and further improves the ease of installation.

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a spring-loaded automotive coolant NTC temperature sensor detection device, including a connector plastic shell 1 and a temperature sensing component disposed at the bottom of the connector plastic shell 1. A mounting base 9 is sleeved on the connector plastic shell 1. The connector plastic shell 1 and the temperature sensing component are both located inside the mounting base 9. A spring-loaded body 11 is movably inserted into the mounting base 9. The spring-loaded body 11 abuts against the outside of the connector plastic shell 1. A limiting groove 10 is formed on the mounting base 9. The limiting groove 10 is connected to the inside of the mounting base 9. The spring-loaded body 11 is movably inserted into the limiting groove 10.

[0022] In practice, when it is necessary to install the temperature sensor structure, the retaining ring body 11 has a certain elasticity, so both ends of the retaining ring body 11 can be bent to deform it. Then, the retaining ring body 11 is movably inserted into the limiting groove 10. Then, the retaining ring body 11 is released, so that the retaining ring body 11 can be restored to its original shape and locked onto the connector plastic shell 1, making it easy to install the connector plastic shell 1. When disassembling, the retaining ring body 11 can be removed from the limiting groove 10 by moving away from it. This process is convenient and does not require tools.

[0023] See Figure 1-4 A lead screw 12 is threaded into one side of the snap ring body 11. A pusher 13 is fixedly installed at one end of the lead screw 12. A torsion block 14 is provided at the other end of the snap ring body 11. The torsion block 14 abuts against the outer surface of the snap ring body 11.

[0024] In practice, based on the above implementation, when it is necessary to pry open both ends of the snap ring body 11 and deform it, the torsion block 14 can be rotated, so that the torsion block 14 drives the lead screw 12 and the pusher 13 to rotate and push one side of the snap ring body 11, so that the two ends of the snap ring body 11 are far apart from each other, which makes it easier for personnel to pry open the snap ring body 11 and further improves the ease of installation.

[0025] See Figure 1-4 The twist block 14 is provided with anti-slip texture 15. This increases the friction between the user's hand and the twist block 14, thereby helping to apply force more effectively when the user rotates the twist block 14.

[0026] See Figure 1-4 Both ends of the retaining ring body 11 are integrally formed with protruding edges 16, which are located outside the limiting groove 10. This facilitates the pulling of the retaining ring body 11 by personnel.

[0027] The temperature sensor includes a terminal 2, which is inserted into the bottom of the connector plastic shell 1. An NTC thermistor 3 is disposed on the terminal 2. A brass shell 5 is disposed at the bottom of the connector plastic shell 1. The terminal 2 and the NTC thermistor 3 are located inside the brass shell 5. An outer sealing ring 6 is also fitted on the terminal 2. A gasket 4 is also fitted at the connection between the connector plastic shell 1 and the brass shell 5. A thermally conductive material 8 is disposed inside the brass shell 5. The thermally conductive material 8 is connected to the NTC thermistor 3. A glass shell 7 is disposed on the terminal 2. The NTC thermistor 3 is disposed on the terminal 2 through the glass shell 7.

[0028] In specific implementation, based on the above implementation, the connector plastic shell 1 and terminal 2 are connected to the external plug-in wire harness structure to achieve electrical connection. By setting an NTC thermistor 3 and placing it in the coolant temperature sensitive area, it can react to temperature changes in a timely manner. This signal is fed back to the control element to adjust the coolant working state in a timely manner. By setting a gasket 4, the pressure between the brass shell 5 and the connector plastic shell 1 can be pressed tightly, which can prevent moisture and water and play a sealing role. By setting an outer sealing ring 6, the sensor can be sealed.

[0029] Working principle: When it is necessary to install the temperature sensor structure, the retaining spring body 11 has a certain elasticity, so both ends of the retaining spring body 11 can be bent to deform it. Then, the retaining spring body 11 is movably inserted into the limiting groove 10. Then, the retaining spring body 11 is released, so that the retaining spring body 11 can be restored to its original shape and locked onto the connector plastic shell 1, so that the connector plastic shell 1 can be easily installed. When disassembling, the retaining spring body 11 can be removed from the limiting groove 10 by pressing the top away. This process is convenient and does not require tools.

[0030] During the above operation, when it is necessary to pry open both ends of the snap ring body 11 and deform it, the torsion block 14 can be rotated, so that the torsion block 14 drives the lead screw 12 and the pusher 13 to rotate and push one side of the snap ring body 11, so that the two ends of the snap ring body 11 are far apart from each other, which makes it easier for personnel to pry open the snap ring body 11 and further improves the ease of installation.

[0031] When the temperature sensing component is used, the connector plastic shell 1 and terminal 2 are first connected to the external plug-in wire harness structure to achieve electrical connection. By setting the NTC thermistor 3 and placing it in the coolant temperature sensitive area, it can react to temperature changes in a timely manner. This signal is fed back to the control element to adjust the coolant working state in a timely manner. By setting the gasket 4, the pressure between the brass shell 5 and the connector plastic shell 1 can be pressed tightly, which can prevent moisture and water and play a sealing role. By setting the outer sealing ring 6, the sensor can be sealed.
