  • Publication number: 20220279643
    Abstract: This application relates to the field of electronic device technologies, and provides an electronic component with an enclosure frame, a circuit board with an electronic component, and an electronic device, to effectively protect the circuit board from being corroded, thereby prolonging a service life of the electronic device. This application is applied to a charging pile for charging a new energy electric vehicle. An electronic component with an enclosure frame includes an enclosure frame and an electronic component. The enclosure frame defines a cavity that is closed or that has one open end; when the electronic component with an enclosure frame is connected to a circuit board, the enclosure frame and the circuit board can define a cavity that is closed or that has one open end.

  • Publication number: 20220240509
    Abstract: Disclosed are an oxazoline compound, a synthesis method therefor and an application thereof. The oxazoline compound has a structure represented by formula (I), wherein in the formula (I), R is selected from groups represented by formula (I-1), formula (I-2), and formula (I-3), where an oxazoline derivative having a novel molecular structure is obtained by introducing a nitrogen heterocycle, an ether bond or a sulfonate structure into the oxazoline compound. The oxazoline derivative is useful in the field of agricultural protection, and has higher acaricidal activity than etoxazole, can inhibit the synthesis of chitin from mites, and can effectively control the embryogenesis and development of eggs of Tetranychus cinnabarinus, as well as the ecdysis process from larvae to adults, and therefore has a significant effect in killing mite eggs and larvae.
