The utility model discloses a sectional embedded PCB convenient to ground relates to embedded PCB field, the utility model discloses a mainboard, the mainboard includes mainboard body, be equipped with a plurality of first embedded slot and a plurality of second embedded slot along the first direction extension along the second direction extension on the mainboard body, the utility model discloses a embedded board is set up, and embedded board combination can perfect fit the grid -like embedded channel of crisscross on the mainboard, and the interference fit further strengthens the connection stability. The detachable design of the pin and the pin slot, cooperate with the anti -drop boss and the arc concave structure, both stable electrical connection and convenient after -sales. In addition, the embedded board edge ladder guide structure and the two -way clamping, the disassembly gap formed by the extension of the welding ear, solve the many pain points of traditional grounding mode together, and the practicality, reliability and maintainability of grounding structure have been improved significantly.

This utility model discloses a multifunctional metal mobile phone cover, relating to the field of mobile phone cover technology. It includes a metal casing body, and its innovation lies in: an inwardly extending U-shaped dustproof protrusion integrally formed at the edge of the SIM card slot opening, covering the left and right sides and top edge of the opening; the inner wall of the dustproof protrusion has a sloping structure, with its end connected to a U-shaped sealing groove and fitted with an elastic sealing strip. When the SIM card tray is inserted, the sloping structure guides the tray to precise positioning and compresses the sealing strip, causing axial compression and radial expansion deformation, tightly filling the gap between the tray and the casing; simultaneously, the U-shaped sealing groove firmly fixes the sealing strip, forming a dynamic sealing interface. This design overcomes the technological limitations of precision molding of metal casings, effectively blocking the path of dust intrusion from the tray's mating gap through the integrated protrusion, sloping guidance, and sealing groove compression mechanism, thus solving the long-term sealing defects of metal covers in the SIM card slot area.
