Abstract
The utility model, which provides to have around screw, the screw on a kind of novel screw hole structure of intelligent terminal, including circuit board, the circuit board, block tin.Circuit board dew copper part adds tin by the way of petal type, can effectively ensure that all directions stress is close or even consistent.And scolding tin has certain softness to avoid circuit board stress deformation.Circuit board dew copper part adds after tin, and scolding tin can be caused to be in stretching Yangjing state extrusion oxygen to play the effect of anti-oxidation well when screwing.Scolding tin due to after stress Yangjing can fully ensure that contact reaches good earthing effect.
Description
Technical field
The application is related to a kind of novel screw hole structure of intelligent terminal.
Background technology
Smart mobile phone mainboard is needed to be fixed on magnesium alloy, and generally we can be realized by the way of screwing.In master
We can also reach the effect of mainboard ground connection by the way of dew copper on plate.
Common mainboard screw dead earth mode：In the exposed annulus pad in mainboard screw hole both sides, side is welded during assembling
Disk is in contact with stud, and opposite side is in contact with cap nut.
It is another to be：Exposed annulus pad side is in contact with stud, and opposite side connects with fixed metal steel disc
Touch.The deficiencies in the prior art are as follows：
1. not resistance to oxidation
Cap nut and dew copper/steel disc and dew copper ＆ cap nuts, stud with easily entered in the middle of dew copper air cause leakage copper,
Stud, cap nut, steel disc oxidation.In the course of time, the ground connection property of mainboard will be affected
2. it is easily caused circuit board deformation
Both modes above are to be contacted by the way of very stiff and demanding, easily due to reasons such as burr, stud unevennesses
Circuit board is caused to deform.
3. earthing effect is poor
By the way of very stiff and demanding, it is easy to cause mainboard and stud, mainboard and nut/steel disc be single-contact either
Contact surface very little.Even steel disc is caused not contacted with leakage copper because lid oil is higher than dew copper.It is a variety of above that ground connection will be caused to imitate
Really undesirable influence working effect.
Utility model content
The main purpose of the application is to provide a kind of novel screw hole structure suitable for intelligent terminal.
The utility model, which is provided on a kind of novel screw hole structure of intelligent terminal, including circuit board, the circuit board, spiral shell
There is block tin around hole, the screw.
Preferably, the block tin is connected with the screw periphery.
Preferably, the block tin is trapezoidal.
Preferably, the block tin is that petal type is connected in screw periphery.
Preferably, the block tin quantity is 8 pieces.
Preferably, the narrow length of side of the trapezoidal block tin is connected with the screw periphery.
Preferably, it is symmetrical arranged centered on the block tin.
Preferably, the quantity of the block tin is not more than 8 pieces.
The beneficial effects of the utility model are that 1. circuit boards dew copper part adds tin by the way of petal type, can be effective
Ensure that all directions stress is close or even consistent.And scolding tin has certain softness to avoid circuit board stress deformation.2. circuit
Plate dew copper part adds after tin, and scolding tin can be caused to be in stretching Yangjing state extrusion oxygen when screwing to be prevented so as to play well
The effect of oxidation.3. scolding tin due to after stress Yangjing can fully ensure that contact reaches good earthing effect.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the accompanying drawing used required in description of the prior art is briefly described, it should be apparent that, drawings in the following description are
Some embodiments of the present utility model, for those of ordinary skill in the art, are not paying the premise of creative labor
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the novel screw hole structural representation of the utility model intelligent terminal.
Embodiment
It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer
Accompanying drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that retouched
The embodiment stated is a part of embodiment of the utility model, rather than whole embodiments.Based on the implementation in the utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made is belonged to
The scope of the utility model protection.
As shown in figure 1, a kind of novel screw hole structure of intelligent terminal, including circuit board, there is screw on the circuit board, institute
Stating around screw has block tin 1.Preferably, the block tin is connected with the screw periphery.Further, the block tin 1 is trapezoidal.
The block tin is that petal type is connected in screw periphery.The quantity of block tin 1 is preferably 8 pieces.The narrow length of side of the trapezoidal block tin 1 with
The screw periphery linking.It is symmetrical arranged centered on the block tin 1.Skilled person will appreciate that, the quantity of the block tin 1 is
Not more than 8 pieces.
In summary, the beneficial effects of the utility model are that 1. circuit boards dew copper part adds tin by the way of petal type,
It can effectively ensure that all directions stress is close or even consistent.And scolding tin has certain softness to avoid circuit board stress from becoming
Shape.2. circuit board dew copper part adds after tin, scolding tin can be caused to be in stretching Yangjing state extrusion oxygen so as to very well when screwing
The effect for playing anti-oxidation.3. scolding tin due to after stress Yangjing can fully ensure that contact reaches good earthing effect.
Finally it should be noted that：Various embodiments above is only limited to illustrate the technical solution of the utility model, rather than to it
System；Although the utility model is described in detail with reference to foregoing embodiments, one of ordinary skill in the art should
Understand：It can still modify to the technical scheme described in foregoing embodiments, or to which part or whole
Technical characteristic carries out equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from this practicality newly
The scope of each embodiment technical scheme of type.
