Embodiment
The locking fixed structure, insulating sleeve and apply its electronic installation of the present embodiment, it is the insulating sleeve utilizing to have a rotation stopping function, what make screw rod locks electrical isolation between fixed structure and metal shell, to overcome the problem of aerial signal decay, and the rotation caused when can prevent screw rod from locking torsion.
Please refer to Fig. 1 and 2 figure, its illustrate respectively according to an embodiment the decomposing schematic representation locking fixed structure and assembling schematic diagram.Lock fixed structure 10 and comprise insulating sleeve 100 and a spline nut 140.Insulating sleeve 100 comprises hollow cylinder 110,1 first spline platform 120 and a projection 130.First spline platform 120 protrudes from the lateral margin of hollow cylinder 110.Projection 130 is configured at a horizontal surface 122 of the first spline platform 120, to form one second spline platform 130.Spline nut 140 is configured in hollow cylinder 110.The top of spline nut 140 has a flange 142, and flange 142 is connected to the horizontal surface 122 of the first spline platform 120, and contact with each other with the second spline platform 130 (or against).
Then, please refer to Fig. 3 and 4 figure, its illustrate respectively according to the electronic installation of an embodiment decomposing schematic representation and assembling schematic diagram.Electronic installation 20 is such as having the portable electric device of communication function, and it has an antenna coverage area 22, in order to receive or to send radio signal, to carry out mobile communication or online.Electronic installation 20 inside comprises a metal shell 16 and and locks fixed structure 10.Metal shell 16 is provided with a fixed part 162, and it is positioned at antenna coverage area 22.In one embodiment, fixed structure 10 is locked configurable in a perforation 162a of fixed part 162.As shown in Fig. 1 and 2 figure, insulating sleeve 100 comprises hollow cylinder 110,1 first spline platform 120 and a projection 130.Hollow cylinder 110 is arranged in perforation 162a, to make hollow cylinder 110 and fixed part 162 fluid-tight engagement.In addition, the first spline platform 120 protrudes from the lateral margin of hollow cylinder 110, and contacts with each other with fixed part 162.
Please refer to Fig. 2, in one embodiment, the first spline platform 120 such as has one first arc-shaped surface 124 and one first vertical plane 126, becomes D shape structure to make the first spline platform 120.The outer diameter D 1 of the first arc-shaped surface 124 is greater than the outer diameter D 2 of hollow cylinder 110, with the lateral margin making the first spline platform 120 protrude from hollow cylinder 110.In the diagram, because the first vertical plane 126 and a sidewall 162b of fixed part 162 contact with each other (or against), insulating sleeve 100 cannot be rotated relative to fixed part 162.Therefore, insulating sleeve 100 can be avoided stressed and rotate in perforation 162a.
In addition, the second spline platform 130 such as has one second arc-shaped surface 132 and one second vertical plane 134, becomes D shape structure to make the second spline platform 130.In Fig. 1 and Fig. 2, the outer diameter D 3 due to flange 142 is greater than the outer diameter D 4 of spline nut 140, and flange 142 can be made to be connected on the horizontal surface 122 of the first spline platform 120.In addition, a sidewall 144 of flange 142 and the second vertical plane 134 contact with each other (or against), spline nut 140 cannot be rotated relative to insulating sleeve 100.Therefore, spline nut 140 can be avoided stressed and rotate in hollow cylinder 110.
Then, please refer to Fig. 3 and Fig. 5, wherein Fig. 5 illustrates the generalized section locking fixed structure according to an embodiment.Lock fixed structure 10 and more comprise a screw rod 150, the bottom of screw rod 150 is bolted in spline nut 140.In one embodiment, electronic installation 20 more comprises a shell body 18, covering metal housing 16, to form a cavity 17 between shell body 18 and metal shell 16.When the bottom of screw rod 150 is placed in cavity 17 through a location hole 18a of shell body 18, locks by screw rod 150 and locking on fixed structure 10, be fixed between shell body 18 and spline nut 140 to make screw rod 150.Also, because insulating sleeve 100 has rotation stopping function, therefore, when screw rod 150 rotates and locks in spline nut 140, insulating sleeve 100 can avoid spline nut 140 to rotate by torsion.
In addition, insulating sleeve 100 is electrical insulator, has the function be electrically insulated.Therefore, when screw rod 150 locks in spline nut 140, insulating sleeve 100 also can electrical isolation between screw rod 150 and metal shell 16 (or fixed part 162), the problem decayed to avoid aerial signal.
Locking fixed structure, insulating sleeve and applying its electronic installation disclosed by the above embodiment of the present invention, it is the insulating sleeve utilizing to have a rotation stopping function, what make screw rod locks electrical isolation between fixed structure and metal shell, to overcome the problem of aerial signal decay.Because the first spline platform of insulating sleeve and the second spline platform can contact with each other with the fixed part of metal shell and spline nut respectively, therefore lock for fixed structure and metal shell relative to the existing screw rod be interconnected, insulating sleeve not only has the function be electrically insulated, the rotation caused when screw rod also can be avoided to lock torsion, to reach effect of rapid-assembling and location.
Certainly; the present invention also can have other various embodiments; when not deviating from the present invention's spirit and essence thereof; those of ordinary skill in the art can make various corresponding change and distortion according to the present invention, but these change accordingly and are out of shape the protection range that all should belong to the claims in the present invention.
