It connects and unstable.Therefore in actual use, especially in such as mobile phone portable electronic product application, loosening is easy tod produce very
To the phenomenon that falling off, so as to cause the electromagnetic interference between device, the phenomenon that influencing the working performance of product.
Therefore, how to provide a kind of shielding case connection structure that fixation is more firm becomes that this field is urgently to be resolved hurrily to ask
Topic.
Utility model content
The purpose of the utility model is to overcome it is above-mentioned in the prior art the shortcomings that, it is high to provide a kind of bonding strength, is not easy
It loosens, to avoid the electromagnetic interference between device, ensures the shielding case connection structure of product working performance.
In order to achieve the above purpose, the shielding case connection structure of the utility model has following constitute：
In the shielding case connection structure, the shielding case includes top plate and the side plate that is set to around the top plate, described
Shielding case connection structure further include the shielding case clip being set on circuit board, the side plate is inserted and fixed in described
In shielding case clip, horizontal convex ribs are additionally provided on the side plate, it is convex that shielding case clip abutting is fixed on the level
Muscle position.
In the shielding case connection structure, shielding case clip includes a pair of of contact pad and a center shell foot, the central elastic
Foot is fixed on the contact pad in outside, and contact pad direction of the center shell foot from the contact pad in the outside inwardly
Extend, the side plate of the shielding case is inserted into and is held between a pair of of contact pad, and the center shell foot abuts
Position above the horizontal convex ribs.
In the shielding case connection structure, the side plate of the shielding case is inserted and fixed to be pressed from both sides in more than two shielding cases
In son.
In the shielding case connection structure, the shielding case is rectangle, on the rectangular shield cover at least two opposite sides
Side plate is inserted and fixed in the shielding case clip.
The shielding case connection structure for using the utility model, due to being provided with horizontal convex ribs, the screen on its side plate
Cover clip abutting is covered to be fixed on the horizontal convex ribs position and to strengthen the frictional force between shielding case clip and shielding case make
Bonding strength is high, and shielding case is not easy to loosen, and to avoid the electromagnetic interference between device, ensures product working performance, and this practicality
The structure of novel shielding case connection structure is simple, and production method is easy, and of low cost, application range is very extensive.
Description of the drawings
Fig. 1 is the partial schematic diagram of shielding case connection structure in the prior art.
Fig. 2 is the structural schematic diagram of the shielding case in the shielding case connection structure of the utility model.
Fig. 3 is the partial schematic diagram of the shielding case connection structure of the utility model.
Specific implementation mode
In order to be more clearly understood that the technology contents of the utility model, spy are lifted following embodiment and are described in detail.
It please refers to shown in Fig. 2, for the structural schematic diagram of the shielding case in the shielding case connection structure of the utility model.
In one embodiment, the shielding case 3 includes top plate 31 and the side plate 32 being set to around the top plate 31,
The shielding case connection structure further includes the shielding case clip 2 being set on circuit board, and the side plate 32 is inserted and fixed
In in the shielding case clip 2, being provided with horizontal convex ribs 33 on the side plate 32, the shielding case clip 2 abuts solid
Due to 33 position of horizontal convex ribs.
In a preferred embodiment, as shown in figure 3, shielding case clip 2 includes a pair of of contact pad 21 and a center
Shell foot 22, which is fixed on the contact pad 21 in outside, and the center shell foot 22 is from the Contact welding in the outside
21 direction of contact pad of disk 21 inwardly extends, and the side plate 32 of the shielding case 3 is inserted into and is held on a docking
Between touching pad 21, the center shell foot 22 abuts the position of 33 top of horizontal convex ribs.
In further preferred embodiment, the side plate 32 of the shielding case is inserted and fixed in more than two described
In shielding case clip 2.
In preferred embodiment, the shielding case 3 is rectangle, the rectangular shield cover 3 at least two opposite sides
On side plate 32 be inserted and fixed in the shielding case clip 2.
In practical applications, the shielding case production program of the utility model is to do one to outside plate in center shrapnel position
Convex slot, when shielding case is inserted into bottom, shell foot is fallen at card slot, is played the role of one and is blocked fixed, and the shielding muscle of evagination
Increase with shielding case clip contact area, increases frictional force.
Shielding case in the prior art, the position folded by shielding case clip are being inserted using straight production method
After entering, it is to carry out fixed mask cover by four contact pads of shielding case clip and the snap-in force to shielding case of center shell foot, stings
Frictional force after conjunction pops up come shielding case when preventing from falling.Drop number is more or usage time is grown, and can lead to shielding case
It is detached from mainboard, to impaired performance or even nonfunctional.The shielding case production method of the utility model makes in cooperation shielding case clip
There is very big promotion in used time in the reliability of the intensity of connection, and is not limited to be applied on mobile phone, can also be applied to need to prevent
Electromagnetic interference and the electronic product that the component in pcb board factory is protected, such as tablet, notebook.Make shielding case
More preferable with the junction intensity of shielding case clip, anti-drop ability is stronger.Also meet the market demand, end-user experience simultaneously
Effect is good.
The shielding case connection structure for using the utility model, due to being provided with horizontal convex ribs, the screen on its side plate
Cover clip abutting is covered to be fixed on the horizontal convex ribs position and to strengthen the frictional force between shielding case clip and shielding case make
Bonding strength is high, and shielding case is not easy to loosen, and to avoid the electromagnetic interference between device, ensures product working performance, and this practicality
The structure of novel shielding case connection structure is simple, and production method is easy, and of low cost, application range is very extensive.
In this description, the utility model is described with reference to its specific embodiment.But it is clear that still can be with
The spirit and scope that various modification can be adapted and converts without departing from the utility model.Therefore, the description and the appended drawings should be considered as
It is illustrative and not restrictive.
