Abstract: Provided is a board-to-board socket, including a socket body, socket terminal, and socket strengthener. The socket body includes a bottom wall, socket side walls, socket guide parts formed at lateral ends of the socket body, and an island part protruding upwards from the bottom wall. Socket guide parts each include a plug guide part receiving cavity, longitudinal outer peripheral wall, and lateral outer peripheral walls. The socket strengthener includes a main body part, lateral outer peripheral wall, and elastic arm parts. Tops of the elastic arm parts bend and extend towards longitudinal outer sides to form hitching part cavities hitched on top faces of the lateral outer peripheral walls.

Abstract: An electronic atomizer includes a cartridge tube provided with an e-liquid storage cavity and a flue, a closure member closing the e-liquid storage cavity, a sealing member, an atomizing core provided in the closure member, and a base. The closure member includes a closure end, an accommodation end extending downward from closure end, a flow passage vertically penetrating through closure member, and an air passage separated from flow passage; the sealing member is integrally formed on closure member and includes a first sealing portion covering outer side of the atomizing core, a second sealing portion covering outer periphery of the closure end and abutting against inner wall surface of the cartridge tube, and a third sealing portion fitted to top end of the air passage and abutting against end edge of the flue; the e-liquid storage cavity communicates with upper end surface of atomizing core through the flow passage.

Abstract: A waterproof card holder includes a card holder frame and a cover plate located at top of the card holder frame. The waterproof card holder includes a sleeve integrated with and extending from an inner side of the cover plate and a through-hole penetrating through the sleeve and the cover plate. A waterproof mechanism is accommodated in the sleeve. The waterproof mechanism includes a main body, a first end portion located inside the sleeve, a second end portion protruding from the sleeve, and a waterproof ring located on a periphery of the main body and close to the first end portion. The waterproof ring and the sleeve form a sliding sealing structure therebetween.

Abstract: A waterproof card holder includes a card holder frame, a cover plate, a sleeve integrated with and extending from an inside of the cover plate, and a waterproof mechanism in the sleeve. A through-hole of the sleeve penetrates through the sleeve and cover plate. The waterproof mechanism includes a first end portion limited inside the sleeve, a second end portion having an outer diameter smaller than that of the first end portion, and a waterproof ring sleeved on a periphery of the first end portion and forming a sliding sealing structure with the sleeve. The sleeve includes first and second openings respectively disposed at two ends of a sleeve body. The first end portion is limited to be only movable within a stroke between the first and second openings. The second end portion being capable of passing through a first opening to be in contact with a card retracting mechanism.
