The fastener and the plastic frame have higher bonding strength. The invention also provides a shell adopting the fastener.
Description
Technical field
The present invention relates to a kind of fastener and adopt the housing of this fastener, relate in particular to a kind of fastener and adopt the case of electronic device of this fastener.
Background technology
Development along with mobile communication technology, various electronic installations such as mobile phone etc. competitively emerge in large numbers, make the consumer can enjoy all facilities that mobile technology is brought whenever and wherever possible, and people are to having higher requirement the useful life of electronic installation, and housing needs equally and can use for a long time as the critical piece of electronic installation.
A kind of mobile phone housing, it comprises plastic frame body and the fastener that combines with plastic frame body.This fastener is the metal lamellar body, and it combines with framework by mode one-body molded or that screw screws togather.
Yet fastener is generally the rectangle sheet, and itself and the integrated bond strength of plastic frame body are lower, and after repeatedly using, fastener is deviate from from plastic frame body easily.If the mode that the employing screw screws togather though can have bigger bond strength, is tightened fastener and plastic frame body one by one on screw and need be expended the more time, production efficiency is lower.
Summary of the invention
In view of above-mentioned condition, be necessary to provide a kind of big with the plastic frame body bond strength and be easy to the fastener that combines with plastic frame body and adopt the housing of this fastener.
A kind of fastener, it comprises main body and is formed at the hook portion of main body one end, offer at least one locking holes on the main body, has interface on the hole wall of locking holes, locking holes flows through for plastic material in injection moulding process, and described locking holes is filled to form the holding section of matching with interface in plastic material cooling back.
A kind of housing, it comprises that plastic frame body reaches and the integrated a plurality of fasteners of plastic frame body, fastener comprises main body and is formed at the hook portion of main body one end, offer at least one locking holes on the main body, have interface on the hole wall of locking holes, plastic frame body is formed with the holding section of matching with interface in locking holes.
When above-mentioned fastener and plastic frame body are one-body molded, but except the hook portion hook is located on the plastic frame body, after plastic material flows through the locking holes of fastener, also can forms the holding section and match, with the bond strength of further enhancing fastener and plastic frame body with interface.

Embodiment
Below in conjunction with drawings and Examples to fastener of the present invention and adopt the housing of this fastener to be described in further detail.
See also Fig. 1, the embodiment of the invention one provides a kind of fastener 30, the hook portion 33 that it comprises the main body 31 that is roughly the rectangle sheet and is formed at main body 31 1 ends.Fastener 30 offers a locking holes 35 in the position of main body 31 contiguous hook portions 33.This locking holes 35 is used for flowing through for plastic material at injection process.In the present embodiment, fastener 30 is a metalwork, and locking holes 35 is roughly isosceles trapezoid, and its size reduces gradually along the direction near hook portion 33.The hole wall of locking holes 35 has two relative linking planes 351.
See also Fig. 2, the embodiment of the invention two provides a kind of fastener 40, it has similar structure to the fastener 30 of embodiment one, and its difference is: main body 41 also offers an installing hole 46 away from an end of hook portion 43, and this installing hole 46 is used for passing and locating for other parts.
See also Fig. 3, the embodiment of the invention three provides a kind of fastener 50, and it has similar structure to the fastener 30 of embodiment one, and its difference is: fastener 50 offers two locking holes 55 side by side in the position of main body 51 contiguous hook portions 53.Be appreciated that and also can offer plural locking holes 55 on the fastener 50.
See also Fig. 4, the embodiment of the invention four provides a kind of fastener 60, and it has similar structure to the fastener 30 of embodiment one, and its difference is: locking holes 65 is half elliptic, and its size reduces gradually along the direction near hook portion 63.The hole wall of locking holes 65 has two relative arc interfaces 651.
See also Fig. 5, the embodiment of the invention five provides a kind of fastener 70, and it has similar structure to the fastener 40 of embodiment two, and its difference is: locking holes 75 is for being roughly rectangle, and its hole wall is formed with two relative coarse interfaces 751.
See also Fig. 6 to Fig. 9, the embodiment of the invention four provides a kind of housing 90, and it comprises integrated plastic frame body 91 and a plurality of fastener 30,40,50.
Above-mentioned housing 60 is made by following forming method:
A plurality of fasteners 30,40,50 are positioned in the injection mold (figure does not show);
Then by injection mold to the plastic material of mold-in injection fusion to form plastic frame body 31, at this moment, plastic material flows through locking holes 35 and the cooling back forms holding section 313.
In the housing 60 after the moulding, hook portion 33,43, the 53 equal hooks of fastener 30,40,50 are located on the plastic frame body 31, can guarantee that fastener 30,40,50 can not deviate from from plastic frame body 31 easily, and, the cross section of this holding section 313 is an isosceles trapezoid, it can support mutually with interface 351 after snapping in locking holes 35,45,55 on the fastener 30,40,50, with the bond strength of further enhancing plastic frame body 31 with fastener 30,40,50.
Be appreciated that, locking holes 35,45,55 also can be other shapes, as triangle, as long as guarantee to be formed with on the hole wall of locking holes 35,45,55 at least one interface 351,451,551 that cooperatively interacts with holding section 313 to increase the bond strength of plastic frame body 31 and fastener 30,40,50.
Be appreciated that, because the hole wall of fastener 60 has arc interface 651, the hole wall of fastener 70 has coarse interface 751, after fastener 60,70 and plastic frame body 31 are one-body molded, plastic frame body 31 can form holding section 313 equally offseting with interface 651,751 or to mesh in locking holes 65,75, thereby strengthens the bond strength of plastic frame body 31 and fastener 60,70.
In addition, those skilled in the art also can do other variation in spirit of the present invention, and certainly, the variation that these are done according to spirit of the present invention all should be included in the present invention's scope required for protection.
