The technical solution provided below in conjunction with attached drawing, each embodiment that the present invention will be described in detail.
The embodiment of the invention discloses a kind of through-hole sealing structure, which can reside in various electronics and sets
In standby, such as television set, washing machine, smart mobile phone, tablet computer etc..It please refers to Fig.1 to Fig. 6, which includes
Mainboard bracket 1, containment member 2, covering 3 and component 4.
Referring to Fig. 1 and Fig. 4, mainboard bracket 1 generally includes plastic body 10 and stainless steel is embedding for connecting other components
Part 12, plastic body 10 is using the larger plastic material injection molding of hardness, and stainless steel inserts 12 then uses stainless steel punching press
Molding, according to differences such as the position of the component of required connection and performances, respectively with the plastic body of mainboard bracket 1 10 or stainless
Steel inserts 12 is attached.When manufacturing, plastic body 10 is molded by injection molding manner, by stainless steel in forming process
Inserts 12 is also placed in the corresponding position of injection mold, and stainless steel inserts 12 is embedded in certainly by plastic body 10 while injection molding
Inside body.
Through-hole 100 is provided on plastic body 10, component 4 is arranged on 10 rear of plastic body of mainboard bracket 1,
According to the difference of component 4, the effect of through-hole 100 also different from.For example, for optics such as camera and infrared sensors
For device, the main function of through-hole 100 is light transmission, and for receiver, the main function of through-hole 100 is then through sound
Wave.Covering 3 can then be arranged on the front of plastic body 10.
The top priority of containment member 2 is gap between sealing covering 3 and plastic body 10, prevent extraneous steam,
Dust etc. enters through-hole 100 by the gap and pollutes component 4.In the present embodiment, containment member 2 passes through injection molding
Mode is directly molded on plastic body 10.Specifically, there are one connection anchor rings 102 for the tool of plastic body 10, connect anchor ring 102 to enclose
It is set around through-hole 100, one can be formed on connection anchor ring 102 during injection molding containment member 2 fit closely connection anchor ring 102
The first sealing ring 20.Since by the way of injection molding, even if the area of connection anchor ring 102 is smaller, first seals
It also still can closely be connected, and be provided simultaneously with good sealing effect between circle 20 and connection anchor ring 102.
It treats that the first sealing ring 20 is molded on connection anchor ring 102 and then deviates from covering 3 by the first sealing ring 20 to connect
The side and the first sealing ring 20 for connecing anchor ring 102 are tightly connected, and can realize that gap is close between covering 3 and plastic body 10
Envelope.Covering 3 in the present embodiment can be blocked the block piece of containment member 2 merely or have decoration work(simultaneously
The case ring of energy also or with other functions and needs to be arranged on the component except containment member 2.
In the present embodiment, in order to make containment member 2 that there is good injection molding performance and sealing performance, structure is sealed
The material of part 2 is preferably plastic cement, such as TPU or TPE etc., and this kind of material has good plasticity, while has higher return
Elasticity is the ideal material of containment member 2.In addition to this, liquid-state silicon gel material can also be used.
However, no matter using which kind of material, with the plastic body 10 of ebonite material used by material exist it is apparent
Difference.Although the first sealing can be made in a manner that injection molding process directly forms containment member 2 on plastic body 10
There is larger bonding strength between circle 20 and connection anchor ring 102, however, since the two is face connection, before material is different
It puts, the bonding strength of two kinds of materials itself is limited after all, when meeting with stronger external force effect, however it remains tear disengaging
Risk, therefore the bonding strength further promoted between plastic body 10 and containment member 2 is significantly.
As shown in Figures 2 and 3, in the present embodiment, anticreep hole 104 is additionally provided on plastic body 10, it is at the same time, close
Seal component 2 in injection molding can also formed fastener 22 simultaneously, fixing piece 22 is molded in the anticreep hole 104, therefore fixing piece
22 can fill anticreep hole 104, and fixing piece 22 is connected with the first sealing ring 20, and the structure in anticreep hole 104 is used to prevent to fix
Part 22 towards the direction of covering 3 by being detached from anticreep hole 22.
Specifically, various structures may be used to prevent fixing piece 22 in anticreep hole 104, for example, anticreep hole 104 can include
Thin neck (not shown), the sectional dimension of thin neck are less than the sectional dimension of the one end of anticreep hole 104 far from covering 3.Due to
Fixing piece 22 is filled in anticreep hole 104, therefore thin neck can form position-limiting action to fixing piece 22, so as to prevent fixing piece 22
By being detached from anticreep hole 104 towards the direction of covering 3., can also be several along lineal layout there are one thin neck can only have, and
And the both ends of thin neck can be connected (such as ladder-type structure) by two in a certain angle facing directly, can also pass through song
Face or inclined-plane carry out transition.
When having thin neck inside anticreep hole 104, the active force between fixing piece 22 and anticreep hole 104 can be concentrated all
Thin neck region, therefore be easy to stress concentration and cause structural failure, also, if thin neck uses hierarchic structure, corner angle
Region is also not easy to be completely filled during injection molding, cause molding fixing piece 22 structural strength it is relatively low.
Therefore, anticreep hole 104 is preferably with uniformly tapered to the one end for closing on covering 3 by one end far from covering 3
Structure.It is this it is tapered can be carried out in a dimension it is tapered, can also be tapered simultaneously on two dimensions.Institute's shape in this way
Into anticreep hole 104 it is whole be all equivalent to a thin neck, the active force between fixing piece 22 and anticreep hole 104 can uniformly be divided
It is dispersed on the inner wall in anticreep hole 104, therefore can have stronger bonding strength.
In order to make the first sealing ring 20 that there is balanced bonding strength, can be set on plastic body 10 simultaneously to
Few two anticreep holes 104, these anticreep holes 104 are circumferentially distributed in connection anchor ring 102, so as to improve the first sealing ring 20
The bonding strength of each position.
