Embodiment

Please refer to Fig. 2, the utility model provides a kind of shielding fixture 1, and it is to fix a shield 3.Usually shielding fixture 1 is to be welded on motherboard 2, and 3 of shields are also to be fixed on motherboard 2 by shielding fixture 1.Therefore another embodiment of the present utility model is to provide a kind of shielding fixed combination, and it comprises shielding fixture 1 described above and shield 3.

Please refer to Fig. 3 A, shielding fixture 1 of the present utility model comprises: a base 10, a clamping part 13 and a limiting section 11.Clamping part 13 is to extend from a side direction of base 10.Limiting section 11 is to extend upward from the opposite side of base 10.Clamping part 13 also is provided with a groove 15.

The preferably, clamping part 13 also comprises a clamping tail end 16, it is positioned at the tail end of the bearing of trend of this clamping part 13, and this clamping tail end 16 is towards the reverse extension (example right side) as shown in Figure 3A of clamping direction, makes the integral body of clamping part 13 slightly be < type.Limiting section 11 comprises a spacing tail end 12, and it is positioned at the tail end of the bearing of trend of this limiting section 11, and this spacing tail end 12 slightly is the integral body of this limiting section 11 towards the reverse extension of clamping direction > type.Spacing tail end 12 extends towards different directions respectively with clamping tail end 16.

Please refer to Fig. 3 B, the short h2 of the height in clamping part 13 of the upwardly extending height h1 of limiting section 11.Thus, the elasticity of clamping part 13 can be relatively good, and the elasticity of limiting section 11 is poor, even may be because the height of limiting section 11 is too low and nonelastic.Beneath by further specified.

Please refer to Fig. 4, shield 3 comprises a wall 30, and wall 30 is provided with a protuberance 31.

Please refer to Fig. 5, the protuberance 31 of shield 3 is the grooves 15 corresponding to clamping part 13.When shielding fixture 1 fixed shield 3, protuberance 31 is the grooves 15 that are positioned at clamping part 13, so that wall 30 is clamped between clamping part 13 and limiting section 11.

When the user will be assembled into shield 3 on shielding fixture 1, because spacing tail end 12 and clamping tail end 16 extend towards different directions respectively, therefore produce a large opening, the user is easy to just the wall of shield 3 30 to be placed between spacing tail end 12 and clamping tail end 16.And as mentioned above, because clamping part 13 is to have flexiblely, once slide into the groove 15 that is positioned at clamping part 13 when protuberance 31, clamping part 13 just can provide chucking power, make wall 30 by being clamped between clamping part 13 and limiting section 11 tightly.

When the user will be when shielding fixture 1 be removed shield 3, as mentioned above, because the elasticity of limiting section 11 bad (even nonelastic), the user only needs to press the clamping tail end 16 of clamping part 13, can make easily protuberance 31 break away from the groove 15 of clamping part 13.Now, the user only need by shield 3 up movement can complete dismounting.

Please get back to Fig. 2, in another embodiment, shielding fixture 1 ' of the present utility model comprises two clamping parts arranged side by side 13, increases whereby the contact area of the wall 30 of itself and shield 3, to strengthen chucking power.Other element at the present embodiment is all same as the previously described embodiments, therefore no longer repeats to repeat.

Same in order to strengthen chucking power, the shielding fixed combination of another embodiment of the utility model includes shielding fixture 1 ' and the shield 3 of above-mentioned paragraph containing two clamping parts 13 arranged side by side.Other element is all same as the previously described embodiments, therefore no longer repeat to repeat.

Certainly; the utility model also can have other various embodiments; in the situation that do 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 to the protection range of the utility model claim.
