The anti-abscission shielding reed provided by the utility model is hard to abscise when in use and solves the problems of electromagnetic leakage due to the reed abscission of sheets in a communication device, short circuit of a circuit board, etc.
Description
Technical field
The utility model relates to a kind of shielding finger, relates in particular to a kind of shielding finger that clamps that the slit shields between the communication apparatus thin plate that is applied to.
Background technology
In electronic equipment or communication apparatus, for solving the caused electromagnetic shielding problem in slit between the sheet member that needs plug, the reliable electric when reed often is installed with assurance equipment operate as normal connects.Present car coat type (C type) reed commonly used in electronic equipment or the communication apparatus generally can both satisfy the performance requirement of shielding, and still, in the process of sheet member plug, the car coat type reed is because stress deformation is easy to come off poor stability.
As shown in Figure 1, be existing C type reed stereogram.This reed structure comprises elasticity circular arc spare 101 and bending straight flange spare 102, and elasticity circular arc spare 101 is one-body molded with bending straight flange spare 102.As shown in Figure 2, be that existing C type reed snaps in and do not compress the free state stereogram in the thin plate mounting groove; As shown in Figure 3, be that existing C type reed snaps in and do not compress the free state cutaway view in the thin plate mounting groove; As seen C type reed 01 is installed in the mounting groove 301 of installation thin plate 02 of communication apparatus, by this kind C type reed is installed, realizes the purpose of electromagnetic shielding between the plugged sheet member of communication apparatus.
As shown in Figure 4, be that existing C type reed is compressed in the cutaway view in the slit.When this C type reed 01 normal mounting was used between thin plate in the slit, C type reed 01 was restrained between the slit that thin plate 02 and relative fixed plate 03 are installed.Because the elasticity circular arc spare 101 stressed compressions of C type reed 01, radian become big, reed 01 broad ways stretches; Bending straight flange spare 102 outwards moves with pressure, keep contacting on a small quantity with the outer installed surface 103 that thin plate 02 is installed, and contact with the contact-making surface 104 of relative fixed plate 03 by elasticity circular arc spare 101, thereby form being electrically connected of thin plate 02 and relative fixed plate 03, and reduce electromagnetic leakage.But because it is shorter usually with the length of bending straight flange spare 102 overlaps of C type reed 01 that the outer installed surface 103 of thin plate 02 is installed, when thin plate 02 is installed with the 03 occurred level relative motion of relative fixed plate, C type reed 01 tangential stress deformation is very easily deviate from the mounting groove that thin plate is installed.
The utility model content
The purpose of this utility model is to provide a kind of shielding finger simple in structure, easy for installation, difficult drop-off in thin plate plug process.
For solving the problems of the technologies described above, slip-off preventing shielding finger of the present utility model comprises: elasticity circular arc spare and the bending straight flange spare and the bending hook member that are attached thereto.
Further, described bending hook member is arranged at described bending straight flange spare edge;
Further, described bending hook member is to distribute along described bending straight flange spare length direction, and acutangulate setting with described bending straight flange spare several slope inwardly and stretch out structure;
Further, described bending hook member is a square structure;
Further, described elasticity circular arc spare, described bending straight flange spare and the described bending hook member three structure that is formed in one;
Further, described reed is formed by conductive foil material bending successively.
The utility model provides a kind of slip-off preventing shielding finger, on the prior art basis, increased the bending hook structure, thereby the plug use in difficult drop-off, solved the communication apparatus thin plate because the electromagnetic leakage that reed comes off and causes, even problem such as circuit board short circuit, the reliability of raising equipment has reduced cost of equipment maintenance.This reed has the advantage that difficulty of processing is low, qualification rate is high, cost is low simultaneously.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
As shown in Figure 5, slip-off preventing shielding finger of the present utility model is formed by conductive foil material bending successively.Comprise the two bending straight flange spares 102 that are fitted on the thin plate, the C type elasticity circular arc spare 101 that connects two bending straight flanges, and bending hook member 111.Described bending hook member 111 along described bending straight flange spare 102 length directions distribute, and acutangulate with it several intilted square structures of stretching out.The utility model reed directly snaps in when using in the mounting groove of thin plate and gets final product.Bending hook member 111 can tightly block the edge that the thin plate mounting groove is installed, and in the use, can effectively prevent to install the reed that the thin plate plug causes and come off.
As shown in Figure 6, be that the utility model reed snaps in and do not compress the free state cutaway view in the thin plate mounting groove.In the present embodiment, thin plate 12 is installed and on the basis that thin plate 02 is installed, is had mounting groove 601.As seen, in the utility model reed 11 directly snaps in mounting groove 301 that thin plate 12 is installed and mounting groove 601 and when not compressing, block thin plate by bending straight flange spare 102, bending hook member 111 does not contact with the mounting groove groove face, does not stress.
As shown in Figure 7 and Figure 8, the utility model reed is compressed between the slit that thin plate 12 and relative fixed plate 03 are installed.C type elasticity circular arc spare 101 compressive deformations of reed 11, it is big that radian becomes, the bending hook member 111 of reed 11 hooks the installation groove face 115 that thin plate 12 is installed thereupon, and the bending straight flange spare 102 of reed 11 contacts with the installation groove face 114 that thin plate 12 is installed, and contacts with the contact-making surface 104 of relative fixed plate 03 by C type elasticity circular arc spare 101.When thin plate 12 is installed with the 03 generation relative motion of relative fixed plate, the C type elasticity circular arc spare 101 of the utility model reed 11 is subjected to tangential force, because the bending hook member 111 of reed 11 hooks the installation groove face 115 that thin plate 12 is installed, reed can not come off in the mounting groove or eject, and has improved the reliability of equipment.
For slip-off preventing shielding finger of the present utility model, can adopt the various conductive foils that are suitable for processing as producing material.
As other embodiment of the present utility model, the bending hook member of the utility model slip-off preventing shielding finger can also be other structure, as diamond structure, semicircular structure and trapezium structure etc.
Certainly; the utility model can also have other execution mode; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong in the protection range of the present utility model.
