Abstract
The utility model discloses a waterproof dust-proof structure for a technological hole on an electronic product, which comprises a sealing plug made of resilient materials and used for blocking the technological hole on the electronic product, wherein the sealing plug is preferably made of silica gel, because the silica gel has good high/low temperature resistance and is easily not aged; the sealing plug can also be made of TPU, rubber or plastic. The sealing plug has a T-shaped and/or L-shaped cross-sectional shape and an external shape coinciding with the external profile of the technological hole. The sealing plug can easily realize an interference fit with a plastic shell by means of the elasticity of the sealing plug, and forms a sealing body with the plastic shell. The sealing body used for blocking salt mist and dust entering a product body thoroughly solves the influence of the dust on the product inside. The utility model can effectively avoid influence of salt fog test on the internal circuit of the product so as to ensure the quality and the lifetime of the product, and can be widely used on cell phones, video cameras, cameras and other products.
Description
Technical field
The utility model relates to a kind of waterproof and dustproof structure that is used on the electronic product, relates in particular to the waterproof and dustproof structure of electronic product fabrication holes such as a kind of mobile phone, video camera, camera, terminal type audio frequency apparatus, laptop computer, portable hard disk.
Background technology
Mobile phone (comprising mobile phone and the PDA mobile phone of being with camera); video camera; camera (containing digital camera); terminal type audio frequency apparatus (mp3 for example; mp4 etc.); laptop computer; regular meeting is applied to FPC (flexible PCB) on the portable hard disk digital products such as (containing USB flash disk); as clamshell phone; FPC will pass from fore shell during assembling; so on fore shell, will offer the assembly technology hole that FPC passes; and former many mobile phones are not all blocked this assembly technology hole after assembling; or paste a PVC sheet and keep off; but effect is undesirable, makes salt mist test; sand and dust test all is difficult to pass through.
The utility model content
Problem to be solved of the present utility model is the waterproof and dustproof structure that is to provide the effective electronic product fabrication hole of a kind of waterproof and dustproof simple and reliable for structure, that cost is low.
The technical scheme that the utility model adopted is: the waterproof and dustproof structure of described electronic product fabrication hole comprises the sealing plug of making in order to the elastomeric material that stops up fabrication hole on the electronic product, sealing plug preferably adopts silica gel, because silica gel high-and low-temperature resistance performance is preferable, be difficult for aging again, also can adopt TPU, rubber or plastic cement to make, the cross sectional shape of described sealing plug is "T"-shaped and/or " L " shape, and profile conforms to the appearance profile of fabrication hole.
Described sealing plug and fabrication hole are interference fit, and the magnitude of interference is preferably 0～0.1mm.
The hardness of described sealing plug is preferably 60 ± 20 degree.
The beneficial effects of the utility model are: because the utility model relies on the elasticity of sealing plug to make sealing plug realize interference fit like a cork with the plastic cement shell, sealing plug becomes a seal with the plastic cement hull shape, this seal is used to block salt fog, sand and dust enter the product fuselage interior, has thoroughly solved the influence of sand and dust to product inside.And effectively prevent the influence of salt mist test to the product internal circuit, thus guaranteed the quality and the life-span of product, can
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural representation of the sealing plug of the utility model embodiment
Fig. 2 is front, the schematic bottom view of the handset front case before the dress sealing plug;
Fig. 3 is the handset front case schematic diagram behind the sealing plug of packing into;
Fig. 4 is the install and fix schematic diagram of sealing plug in mobile phone inside.
Embodiment
The utility model can be applicable to mobile phone (comprising mobile phone and the PDA mobile phone of being with camera), video camera, camera (containing digital camera), terminal type audio frequency apparatus (for example mp3, mp4 etc.), laptop computer, portable hard disk digital products such as (containing USB flash disk), is that example describes to be applied to clamshell phone only at this.
As shown in Figure 1, for adapting to the positional structure of clamshell phone fabrication hole, present embodiment combines consideration with clamshell phone rotating shaft dismounting fabrication hole 2 and FPC installing technological hole 3, the waterproof and dustproof structure of electronic product fabrication hole is designed to the sealing plug 1 that a hardness that is " T+L " type structure is 60 degree ± 20 degree, sealing plug adopts silica gel to make in this embodiment, this sealing plug cooperates the employing interference fit with clamshell phone rotating shaft dismounting fabrication hole and FPC installing technological hole, and the magnitude of interference is 0～0.1mm.
As Fig. 2, shown in Figure 3, sealing plug 1 is packed into behind clamshell phone rotating shaft dismounting fabrication hole 2 and the FPC installing technological hole 3, protuberance on sealing plug 1 " T " or " L " is clamp-oned in clamshell phone rotating shaft dismounting fabrication hole 2 and the FPC installing technological hole 3, handset front case 5 is close on its base, sealing plug 1 forms a seal with fore shell 5, and this sealing physical efficiency is effective to block button, the main board that salt fog, sand and dust enter main frame.
Fig. 4 is the install and fix schematic diagram of sealing plug in mobile phone inside, and as shown in the figure, fixing of sealing plug 1 limits sealing plug mobile and rotation in the horizontal direction by positioning bar 4 screens in the horizontal direction; In vertical direction, the inner surface by main PCB plate and fore shell 5 clamps sealing plug 1, thus the moving and rotating of restriction sealing plug 1 in vertical direction.
Claims (4)
