Description

Technical Field

[0001] The utility model relates to the technical field of testers, in particular to a simulated NTC temperature sensor tester. Background Art

[0002] NTC temperature sensor is a thermistor and probe, and its principle is that the resistance value decreases rapidly as the temperature rises. It is usually composed of 2 or 3 metal oxides, mixed in a fluid-like clay, and sintered into a dense sintered ceramic in a high-temperature furnace. The test environment usually refers to the equipment or environment where the NTC temperature sensor is located, such as electronic equipment, automobiles, environmental monitoring, etc. Different test environments will have different effects on the performance and reliability of the NTC temperature sensor. And applied to the tester, the NTC temperature sensor is used as the core component of the tester so that the tester can detect temperature characteristics in real time.

[0003] In the prior art, the display screen on the tester is basically exposed to the outside, and there is no corresponding structure to protect the display screen. This causes the display screen to be easily damaged by external foreign objects when not in use, or to be worn by external foreign objects, resulting in damage or scratches on the display screen, making the tester unable to display the test results. Therefore, an analog NTC temperature sensor tester is proposed. Utility Model Content

[0023] The following is a detailed description of the specific settings and functions of this embodiment. The setting of the protective plate 21 can block the display screen 14, prevent external foreign objects from causing impact or friction on the display screen 14, increase the service life of the display screen 14, and facilitate the staff to observe the results on the display screen 14. At the same time, when the fixing plate 27 moves to the middle of the two groups of fixing seats 272, by rotating the two groups of bolts 273 one by one, the two groups of bolts 273 are respectively rotated inside the two groups of fixing seats 272, and one end of the two groups of bolts 273 will be threaded inside the two groups of limiting L plates 29, respectively, so that the protective plate 21 can be fixed in the middle of the two groups of fixing seats 272, thereby preventing the protective plate 21 from swinging and improving the stability of the protective plate 21.
