Description
Technical field
Invention relates to a kind of hand-held set, is specifically related to a kind of hand-held set with water resistance, belongs to electronic information technical field.
Background technology
Hand-held set on market all adopts dual-color forming or two-shot process now, and rubber and housing are integrated, and realizes water-proof function.This technique has higher requirements to Design of Dies, and is larger to the limitation of product design, and the process-cycle is long, realizes that cost is high.
Summary of the invention
In view of this, the invention provides a kind of watertight handheld machine, this hand-held set comprises mainboard, fore shell, back cover, display screen, keyboard, probe, battery cover, connector, tail is slotting and side switch.
Mainboard is the core component of this hand-held set, is arranged in the main frame that is comprised of fore shell and back cover.In order to guarantee the sealing of mainboard, be provided with sealing ring in the junction of fore shell and back cover, sealing ring is positioned at the seal groove on back cover, and the extruding after sealing ring is fastening by front and rear casing realizes waterproof.Because the girth of fore shell and back cover junction is larger, the conventional seals circle is difficult for coordinating with seal groove on back cover, so is provided with two above locating pieces in the inboard of sealing ring.Due to the restriction that sealing ring place size is installed, described locating piece vertical and plane, sealing ring place.According to the position of locating piece on sealing ring, be processed with the mounting groove of locating piece on the seal groove of back cover, when sealing ring is installed, only need first each locating piece to be fixed in corresponding mounting groove, just can complete the installation to sealing ring.
Display location has good water resistance in the upper surface of fore shell for guaranteeing display screen, prevents simultaneously main frame to the wearing and tearing of display screen, in the junction of display screen and fore shell, the sealing cushion blocking is installed.The sealing cushion blocking is the square structure that elastomeric material is made, and is processed with the groove that mates with screen size on the mating surface of sealing cushion blocking and display screen, and display location is in this groove.Be processed with the through hole with display screen screen size coupling on the mating surface of sealing cushion blocking and fore shell.Be processed with projection along this through hole surrounding simultaneously on the mating surface of sealing cushion blocking and hand fore shell, this projection and fore shell interference fit realize the water resistance of this position.
Keyboard is positioned at the upper surface of fore shell, the below of display screen.Install on fore shell in the groove of keyboard and be provided with flexible glue, after keyboard was installed, the projection of keyboard bottom contacted with flexible glue, and keyboard and fore shell are realized the waterproof of keyboard by the interference fit with flexible glue.
Connector is hand-held set mainboard and the extraneous interface unit that carries out transfer of data, and on connector, an end of pin is connected with mainboard, and the other end provides external interface.Be the safety and reliability that guarantees that hand-held set uses, middle connector has carried out the water proofing property design.Described connector is arranged on the afterbody of the main frame that is comprised of fore shell and back cover.Substrate and the pin of connector are carried out integrated processing by the method for in-mould injection, thereby eliminate the gap between pin and substrate, guarantee that extraneous liquid or dust can not enter mainboard, realize the water resistance of connector self.For guaranteeing the sealing between connector and hand-held set main frame, in the junction of connector base board and main frame, waterproof washer is installed simultaneously, is realized the waterproof between connector and main frame.
The tail slot is in the afterbody of the main frame that is comprised of fore shell and back cover.Tail insert to be used for providing hand-held set and the outside interface that carries out data interaction or charging, plugs the interface that is provided with external connection at tail, and these interfaces can not seal the hand-held set main frame fully, therefore needs to improve tail and inserts water resistance with the main frame junction.Tail is inserted and is whole plastic pressure forming structure, can guarantee the water resistance of himself.Tail is inserted and to be comprised pedestal, ring sealing base and pilot seal seat, and wherein ring sealing base and pilot seal seat all are positioned on pedestal and end face that main frame coordinates.Ring sealing base is the closed ring structure that is raised up by base plane, and ring sealing base inside arranges the pilot seal seat, and the pilot seal seat is the open circles annular of projection.After tail was inserted and installed, the pilot seal cover for seat was contained on the excircle of DC interface, realized the sealing to the DC interface, can also insert tail when the pilot seal seat coordinates with the DC interface simultaneously to play the guiding role.Simultaneously the notch cuttype step surface interference fit of the pedestal inserted of tail and ring sealing base and hand-held set main frame afterbody realizes the sealing of main frame and tail slotting junction.
The side button is positioned at the left and right side of hand-held set main frame, annular protrusion on side button silica gel main body contacts with the fore shell side, location hole on the silica gel main body positions with hot melt with reference column on body frame and is fixedly connected with, and the faying face of guaranteeing annular protrusion on the silica gel main body and body frame can fit tightly to realize the function of waterproof.
Probe is arranged on the top of main frame, and scan screen is bonded together by double faced adhesive tape and body frame, realizes the waterproof of this position.
Battery cover is arranged on the back of back cover, for guaranteeing the seal of battery, is processed with projection on the joint face of battery cover and back cover, and with after back cover is connected, the flexible glue interference fit on this projection and back cover realizes the waterproof of this position to battery cover by buckle.
Because the position that loudspeaker, microphone and buzzer are installed on main frame all is processed with through hole so that the appearing of sound, in by have the Air Filter of water-proof function in the lead to the hole site bonding, realize the waterproof of this type of position.
LED light is bonded together LED light-guiding pillar and fore shell by double faced adhesive tape, and then the mode by hot melt is fixed to light-guiding pillar on fore shell, realizes waterproof.
Beneficial effect:
(1) connector waterproofing design: the integrated processing of the pin of connector and substrate, eliminate the gap between pin and substrate, guarantee that extraneous liquid or dust can not enter mainboard, to realize the waterproof of connector self; Simultaneously between connector and main frame, waterproof washer is installed, is realized the waterproof between connector and main frame.
