Description

Technical Field

[0001] The present application relates to the technical field of jigs, and in particular to a contact heating device and a contact heating system for an aging jig. Background Art

[0002] High-temperature aging is to test product performance, discover product defects as early as possible, and improve them to prevent unqualified products from entering the market.

[0003] Aging tests are mainly high-intensity tests that simulate various harsh conditions that products may encounter during actual use. High-temperature aging tests are used to determine the suitability of products for storage, transportation, and use in high-temperature climate environments.

[0004] In existing high-temperature aging tests, heating jigs are constructed by embedding heating tubes inside the base plate of the heating jig, which are evenly distributed throughout the heating area. However, since the heating tubes and the jig are integrated, the jig base plate, in addition to its normal thickness, must also increase the space for burying the heating tubes and the thickness to ensure the heating effect and heat conductivity. This results in a thick base plate and a large overall size. In addition, the power supply for the heating tubes and the temperature sensor must be controlled by a PG provided through a PCB board. Therefore, the PCB board and PG board of the jig power supply system need to be designed independently, which is expensive and has low versatility. In addition, when replacing the heating tubes in existing heating jigs, the jig needs to be disassembled and assembled, which significantly reduces the lifespan and accuracy of the jig.
