Utility model content
In order to overcome above-mentioned defect, the utility model provides a kind of earphone base reinforced protection architecture, and this earphone base reinforced protection architecture has effectively strengthened the resistance of failure of earphone base.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of earphone base reinforced protection architecture; plastic parts one end of earphone base is formed with the earphone jack plugging for headset plug; the elastic tip of some terminals stretches in this earphone jack; also be provided with a metal-back; this metal-back fixed packet is overlying on earphone base and arranges the plastic parts outside of earphone jack section; and metal-back is radially respectively equipped with at least one leg in two opposite sides along earphone base jack, and this leg be able to be welded on circuit board.
As further improvement of the utility model, the described metal-back structure that takes the shape of the letter U, leg is to be arranged at respectively the bending edges extending to open outer side on this U-shaped structural openings both sides sidewall.
As further improvement of the utility model, described metal-back is positioned at the earphone jack openend of earphone base.
As further improvement of the utility model, described earphone base plastic parts has been provided with inner groovy structure on the surface of earphone jack section, metal-back is just placed in this inner groovy, and metal-back is distinguished backstop in the madial wall of earphone base plastic parts inner groovy along the axial both ends of the surface of earphone jack.
As further improvement of the utility model, on described earphone base plastic parts lateral wall, be also provided with at least one bulge-structure, metal-back is provided with and earphone base plastic parts projection locations of structures and the draw-in groove that mate of size, the bulge-structure on earphone base plastic parts be able to metal-back on draw-in groove fix engagement connection.
As further improvement of the utility model, if an earphone base plastic parts dorsad side surface of circuit board is upper surface, be front end face towards a side surface of earphone jack opening direction, described earphone base plastic parts upper surface and front end face joint be formed with one with axially vertical protruding stiffener of earphone jack, metal-back front end face backstop is in this projection stiffener.
The beneficial effects of the utility model are: the utility model by overlapping a metal-back on the plastic parts of earphone base, and metal-back by leg together with welding circuit board, metal-back plays constraint effect to plastic parts earphone jack sidewall, improve the intensity of plastic parts earphone jack sidewall, avoid earphone base to be in use subject to the external force damage of breaking, metal-back has strengthened the bonding strength of earphone base and circuit board together with welding circuit board, effectively avoid earphone base to cause the situation that terminal soldering portion tension is snapped to occur because pulling capacity is excessive, it is simple in structure, intensity is high, long service life.
