Description

Technical Field

[0001] The present invention relates to the technical field of temperature sensors, and more specifically, to an NTC temperature sensor for automobile air conditioners. Background Art

[0002] NTC temperature sensor refers to a thermistor with a negative temperature coefficient, whose resistance value decreases with the increase of temperature. This characteristic enables the NTC temperature sensor to accurately detect temperature changes in the automobile air conditioning system and convert these changes into electrical signals, thereby controlling the cooling or heating function of the air conditioning system to maintain the constant temperature in the car. According to the patent document CN210005128U, a NTC temperature sensor for automobile air conditioning PTC heating includes a base plate, a shell cover and an NTC temperature sensor. The shell cover is fixedly installed on the upper end surface of the base plate, and the NTC temperature sensor is arranged inside the shell cover. A superconducting epoxy resin layer is arranged between the NTC temperature sensor, the shell cover and the base plate. The utility model is an NTC temperature sensor for automobile air conditioning PTC heating. By setting a hook, a superconducting epoxy resin layer and an encapsulating insulating layer, etc., it is convenient to install, improve the service life of the NTC temperature sensor, and improve the thermal conductivity efficiency. The effect solves the problems of low thermal conductivity and inconvenient installation of the current NTC temperature sensor for automobile air conditioning PTC heating.

[0003] NTC temperature sensors are usually connected to the control circuit of the car air-conditioning system through a female connector. During the connection process, it is necessary to ensure that the sensor wiring is correct to avoid signal transmission errors that may cause the air-conditioning system to malfunction.

This connection method has certain risks because the temperature sensor is installed in the car chassis. For example, in severe weather conditions, the staff's hand movements may not be stable enough, resulting in a loose connection. When the car encounters bumps, the sensor connection may become loose, affecting the normal operation of the air-conditioning system. Summary of the invention

The tape wrapping method is troublesome, and when the whole body needs to be disassembled for maintenance, it is also troublesome to cut the tape. If the tape encounters water or the temperature inside the chassis is high, it may cause the tape to lose its viscosity, thereby affecting the overall stability and safety. The connection mechanism 3 of the present invention can achieve a fast and stable connection through the use of a hydraulic push rod 34 and a push block 35. When installation is required, it only needs to be hydraulically The push rod 34 is started, and the push block 35 moves toward the bottom under the action of the hydraulic push rod 34, pushing the push plate 36 to move toward the bottom. When the push plate 36 moves toward the bottom, the pull block connecting block 385 is pressed to pull the pull block 384, thereby making the two right-side clamping jaws 381 rotate on the inner wall of the connecting mechanism hinge block 32, and through the tooth blocks 383 on the outer wall of the toothed disc 382 on both sides and the tooth blocks 383 on the outer wall of the toothed disc 382 on the other side, the two sets of clamping jaws 381 rotate, thereby making the two arc-shaped clamping plates 386 rotate inward, and clamped on other lines through the two sets of arc-shaped clamping plates 386, so that the device as a whole is connected to the outer wall of other lines.

[0022] Working principle of the present invention: when installing the temperature sensor body 1, the staff connects the female connector through the female connector connection mechanism 2 on the rear side of the temperature sensor body 1. The staff first aligns the female connector with the interface 2214, and then inserts the female connector into the inner wall of the interface 2214. When the female connector is inserted into the inner wall of the interface 2214, the outer wall of the female connector pushes against the front side of the inner side of the two V-shaped rotating rods 2216, so that the two V-shaped rotating rods 2216 rotate on the inner wall of the hinge block 2215, so that the positioning block 2217 on the rear side of the V-shaped rotating rod 2216 is tightly attached to the outer wall of the female connector, and then the female connector is preliminarily fixed. At this time, the female connector is fixed on the inner wall of the sliding frame 2211 and the rear connecting shell 214, and then the female connector is continued to be pushed to slide forward on the inner wall of the female connecting shell 21 so that the female connector is connected to the plug on the rear side of the temperature sensor body 1. When the frame 2211 and the interface 2214 and the female connector continue to move forward on the inner wall of the connecting shell 211, at this time, since the outer wall of one side of the two second rotating rods 2224 is hinged on the inner wall of the two sliding frame hinge grooves 2212 opened on the sliding frame 2211, when the sliding frame 2211 moves forward and pulls the two second rotating rods 2224 to drive the arc-shaped side plates 2221 to rotate inward, the two arc-shaped side plates 2221 rotate inward and then pull the rotating rod 2223 and the C-shaped fixing clamp connecting rod 2225 to move inward. When the female connector and the rear side of the temperature sensor body 1 are fully closed, the semicircular fixing grooves 2227 opened on the inner sides of the two C-shaped fixing clips 2226 fix the line on the rear side of the female connector to ensure the stability and sealing of the connection. The entire connection process is simple and quick, which greatly improves the installation efficiency and the convenience of operation. In addition, the design of the female connector also takes into account the needs of dust and water resistance. Through reasonable structural design, the female connector can maintain good working condition even in harsh environments, thus extending the service life of the sensor. After the temperature sensor body 1 is stably connected to the female connector, since the whole body is in the front chassis of the car, it is usually directly suspended in the front chassis of the car, or the whole body is wrapped around the outer wall of other lines by tape. The tape wrapping method is troublesome, and when the whole body needs to be disassembled for maintenance, it is also troublesome to cut the tape. If the tape encounters water or the temperature inside the chassis is high, it may cause the tape to lose its viscosity, thereby affecting the overall stability and safety. The connection mechanism 3 of the present invention can achieve a fast and stable connection through the use of a hydraulic push rod 34 and a push block 35. When installation is required, it only needs to be hydraulically The push rod 34 is started, and the push block 35 moves toward the bottom under the action of the hydraulic push rod 34, pushing the push plate 36 to move toward the bottom. When the push plate 36 moves toward the bottom, the pull block connecting block 385 is pressed to pull the pull block 384, thereby making the two right-side clamping jaws 381 rotate on the inner wall of the connecting mechanism hinge block 32, and through the tooth blocks 383 on the outer wall of the toothed disc 382 on both sides and the tooth blocks 383 on the outer wall of the toothed disc 382 on the other side, the two sets of clamping jaws 381 rotate, thereby making the two arc-shaped clamping plates 386 rotate inward, and clamped on other lines through the two sets of arc-shaped clamping plates 386, so that the device as a whole is connected to the outer wall of other lines.
