Referring to fig. 1 and 2, a leakage detecting device suitable for use in a high temperature environment according to a preferred embodiment of the present invention will be described in detail below. The leakage detection device suitable for the high-temperature environment is used for detecting the leakage condition of an electronic element through a leakage detection graphic instrument, wherein the leakage detection graphic instrument is preferably implemented as a transistor graphic instrument, and the electronic element is correspondingly exemplified by a transistor.

The leakage detecting device comprises a hot plate 10, a heating element, a heat insulation element 20 and a temperature control element 30, wherein the heating element is arranged inside the hot plate 10 and is used for heating the hot plate 10, so that a specific high-temperature environment is provided for the leakage detecting electric operation of the electronic element. Meanwhile, the heat insulation element 20 is arranged to wrap the bottom and the side of the hot plate 10, so that the hot plate 10 is insulated at the bottom and the side, and a space is reserved on the upper surface of the hot plate 10 for bearing the electronic element, thereby facilitating the leak detection of the electronic element. In addition, the temperature control element 30 is connected to the heating element in a manner that the temperature of the heating element can be displayed and adjusted, so that a corresponding high-temperature environment can be simulated for different electronic elements or different requirements.

When the electronic element is subjected to leakage detection, one wire of the leakage graphic instrument is connected to the hot plate 10 to serve as a cathode; the electronic component is placed on the surface of the hot plate 10, and at the same time, another wire of the leak detector is used as an anode and connected to the surface of the electronic component to form a complete loop to test whether the electronic component leaks electricity. Obviously, the electrical leakage detection device also comprises a switch 31 for controlling the opening and closing of said temperature control element 30.

Therefore, aiming at various electronic elements and different high-temperature working requirements of the same electronic element, the leakage detection device can quickly and stably simulate different high-temperature environments, so that the leakage detection work of the electronic element is facilitated, the detection is simple, the test cost is low, the energy is saved, and the application range is wide.

In addition, the leakage detection device is convenient to carry out leakage detection, and the whole structure of the leakage detection device is more compact. Preferably, the leakage detecting device further comprises a main housing 40, wherein the main housing 40 forms a receiving groove 401 for receiving the heat plate 10 and the insulating member 20, so that the insulating member 20 can be tightly wrapped on the heat plate 10 and can effectively fix the heat plate 10. Meanwhile, the temperature control member 30 is disposed on the main housing 40 to form an integrated structure, which facilitates the movement and storage of the leakage detecting device.

Further preferably, the heat insulation element 20 is made of heat insulation cotton, which is not only resistant to high temperature and not easy to burn, but also has a low thermal conductivity, and can effectively keep the heat of the heat plate 10 warm.

It is worth mentioning that, in the process of performing a high-temperature test, the heat is more and is difficult to be dissipated quickly, which is likely to cause aging of various circuit parts and the like wrapped by the heat insulation element 20, and further, the fault is likely to occur, which affects the service life of the leakage detecting device. Further preferably, the side of the main housing 40 is provided with a plurality of heat dissipation holes 402 at intervals, which are communicated with the heat insulation element 20. The heat dissipation holes 402 are preferably implemented as bar-shaped holes, kidney-shaped holes, or densely-arranged circular holes or square holes. Therefore, in the testing process, slow heat dissipation does not affect the high-temperature test, and after the test is finished, the heat dissipation speed of each circuit part wrapped by the heat insulation element 20 can be effectively increased, the service life of each circuit part inside the heat insulation element is prolonged, and the heat insulation element is safer to use.

As a preferred embodiment, the surface of the heat plate 10 is flush with the opening of the receiving groove 401, or lower than the opening of the receiving groove 401, so as to facilitate the placement of the electronic component on the surface of the heat plate 10, and the heat insulating element 20 and the heat plate 10 are not easily touched, thereby improving the safety of operation.

In a preferred embodiment, the temperature control element 30 is implemented as a temperature control meter, and the temperature control element 30 is connected to the hot plate 10 by a thermocouple 32 and is electrically connected to the heating element by a wire. Thermocouples (thermocouples) are commonly used temperature measuring elements in temperature measuring instruments. It directly measures the temperature of the hot plate 10 and converts the temperature signal into a thermal electromotive force signal, which is converted into the temperature of the measured medium by an electrical instrument (secondary instrument), such as the temperature control meter 30, so that the temperature of the hot plate 10 can be displayed in real time by the temperature control element 30, and based on this, the temperature control element 30 in turn adjusts the temperature of the hot plate 10 by a wire and the heating element until the temperature of the high temperature environment to be simulated is reached. That is, the temperature control element 30 can not only display the temperature of the hot plate 10 in real time, but also flexibly adjust the temperature of the hot plate 10, and stabilize the hot plate 10 at a certain high temperature, so as to simulate a high temperature environment, and then test whether the electronic element leaks electricity in the high temperature environment.

Preferably, the electrical leakage detection device further comprises an alarm 50. The alarm 50 is mounted on the main housing 40 and electrically connected to the temperature control element 30 to give an alarm when the temperature of the heat plate 10 exceeds a predetermined temperature, so as to warn the operator to prevent the heat plate 10 and the electronic components from being damaged by further heating. The alarm 50 may be implemented as an acoustic alarm device, such as a buzzer; may also be implemented as a light warning device, such as a flashing light; or a combination of an audible alarm device and a light alarm device, and is not particularly limited herein.

In addition, the main housing 40 is preferably made of PPR material. PPR is an abbreviation for pentatricopeptide repeats, also known as random copolymer polypropylene (PPR), which has good product toughness, high strength, excellent processability, good creep resistance at higher temperatures, and has the advantage of high transparency peculiar to random copolymer polypropylene, making the main housing resistant to high temperatures and non-conductive, more resistant to high temperatures relative to plastic housings, and capable of preventing electrical leakage relative to metal housings.
