Abstract
The invention provides a novel screw hole structure of an intelligent terminal. The novel screw hole structure includes a circuit board, a screw hole is arranged in the circuit board, and tin blocks are arranged around the screw hole. A copper-exposing part of the circuit board adopts petal type tin adding, and thus an effect that stress of each direction is close and even consistent can be effectively ensured. Soldering tin has certain softness, thereby preventing stress and deformation of the circuit board. After the copper-exposing part of the circuit board is subjected to tin adding, during screwing, soldering tin can be caused to be in a stretched flattened state, and oxygen is extruded, thereby achieving an effect of preventing oxidation. The soldering tin is flattened after being stressed, contact is fully ensured and a good grounding effect is achieved.
Description
Technical field
The application is related to a kind of novel screw hole structure of intelligent terminal.
Background technology
Smart mobile phone mainboard needs to be fixed on magnesium alloy, and generally we can be realized by the way of screwing.Leading
On plate, we also can reach the effect of mainboard ground connection by the way of dew copper.
Common mainboard screw dead earth mode：In the exposed annulus pad in mainboard screw hole both sides, side weldering during assembling
Disk is contacted with stud, and opposite side is contacted with cap nut.
Another kind is：Exposed annulus pad side is contacted with stud, and opposite side is connected with fixing metal steel disc
Touch.The deficiencies in the prior art are as follows：
1. not resistance to oxidation
Cap nut with dew copper/steel disc with dew copper ＆ cap nut, stud with dew copper in the middle of easily enter air lead to leak 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 above modes are and are contacted by the way of very stiff and demanding, easily due to reasons such as burr, stud unevennesses
Circuit board is led to deform.
3. earthing effect is poor
By the way of very stiff and demanding it is easy to lead to mainboard and stud, mainboard and nut/steel disc be single-contact or
Contact surface very little.Even because lid oil leads to steel disc not contact with leakage copper higher than dew copper.Above a variety of will lead to ground connection effect
Really undesirable impact working effect.
Content of the invention
The main purpose of the application is to provide a kind of novel screw hole structure being applied to intelligent terminal.
The present invention provides a kind of novel screw hole structure of intelligent terminal, including circuit board, described circuit board has screw, institute
State and around screw, have block tin.
Preferably, described block tin is connected with described screw periphery.
Preferably, described block tin is trapezoidal.
Preferably, described block tin is connected in screw periphery for petal type.
Preferably, described block tin quantity is 8 pieces.
Preferably, the narrow length of side of described trapezoidal block tin is connected with described screw periphery.
Preferably, it is symmetrical arranged centered on described block tin.
Preferably, the quantity of described block tin is not more than 8 pieces.
Beneficial effects of the present invention are that 1. circuit board dew copper part adds tin by the way of petal type, can effectively ensure
All directions stress is close or even consistent.And scolding tin has certain softness thus avoiding circuit board stress deformation.2. circuit board dew
After copper part adds tin, scolding tin when screwing, is may result in be in stretching Yangjing state extrusion oxygen thus playing anti-oxidation well
Effect.3. scolding tin due to after stress Yangjing can fully ensure that contact reaches good earthing effect.
Brief description
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
Have technology description in required use accompanying drawing be briefly described it should be apparent that, drawings in the following description are these
Some bright embodiments, for those of ordinary skill in the art, without having to pay creative labor, acceptable
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is the novel screw hole structural representation of intelligent terminal of the present invention.
Specific embodiment
Purpose, technical scheme and advantage for making the embodiment of the present invention are clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described it is clear that described embodiment is
The a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment being obtained under the premise of not making creative work, broadly falls into the scope of protection of the invention.
As shown in figure 1, a kind of novel screw hole structure of intelligent terminal, including circuit board, described circuit board has screw, institute
State and around screw, have block tin 1.Preferably, described block tin is connected with described screw periphery.Further, described block tin 1 is trapezoidal.
Described block tin is connected in screw periphery for petal type.Described block tin 1 quantity is preferably 8 pieces.The narrow length of side of described trapezoidal block tin 1 with
Described screw periphery linking.It is symmetrical arranged centered on described block tin 1.Skilled person will appreciate that, the quantity of described block tin 1 is
It is not more than 8 pieces.
In sum, beneficial effects of the present invention are, 1. circuit board dew copper part adds tin by the way of petal type, can have
The guarantee all directions stress of effect is close or even consistent.And scolding tin has certain softness thus avoiding circuit board stress deformation.2.
After circuit board dew copper part adds tin, scolding tin when screwing, is may result in be in stretching Yangjing state extrusion oxygen thus playing well
The effect of 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 only in order to technical scheme to be described, is not intended to limit；To the greatest extent
Pipe has been described in detail to the present invention with reference to foregoing embodiments, it will be understood by those within the art that：Its according to
So the technical scheme described in foregoing embodiments can be modified, or wherein some or all of technical characteristic is entered
Row equivalent；And these modifications or replacement, do not make the essence of appropriate technical solution depart from various embodiments of the present invention technology
The scope of scheme.
