Embodiment
Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The utility model provides a kind of shielding finger.
With reference to the local structural graph that figure 1 ~ 5, Fig. 1 is the utility model shielding finger installment state; Fig. 2 is the exploded perspective view of Fig. 1; Fig. 3 is the exploded perspective view of the utility model shielding finger and cover plate; Fig. 4 is the part-structure figure of the utility model shielding finger one angle; Fig. 5 is the sectional view of the utility model shielding finger.The shielding finger 10 that the present embodiment provides, this shielding finger 10 is formed by metal material manufacture, is located between Cross beam for plug-in box 20 and cover plate 30, keeps conducting electricity connectivity to make Cross beam for plug-in box 20 and cover plate 30.Particularly, the raw material of shielding finger 10 are thin spring stainless steel, manganese steel spring leaf (heat treated) or thin beryllium copper sheet.It should be noted that shielding finger 10 utilizes metal stamping die, by strip material continuous stamping, shaping, do not limit by length, can random length, free cutting.
Shielding finger 10 comprises: the first side plate 101, second side plate 102, connecting plate 103 and abutting part 104.
First side plate 101 and the second side plate 102 form by metal material manufacture, and both all have elasticity.In the present embodiment, the first side plate 101 and the second side plate 102 are oppositely arranged, for clamping the lower hem 301 of cover plate 30.Connecting plate 103 is located at the position between the first side plate 101 and the second side plate 102.Particularly, the first end of connecting plate 103 is connected with the first side plate 101, and the second end of connecting plate 103 and the connection of described second side plate 102, arranged to make the overall U-shaped shape of shielding finger.It should be noted that the shielding finger 10 of the shape setting that takes the shape of the letter U clamps the lower hem 301 of cover plate 30.Lower hem 301 comprises medial surface 3011 and lateral surface 3012.Can clamp lower hem 301, first side plate 101 of cover plate 30 for making shielding finger 10 and the minimum range of the second side plate 102 is S1, the minimum range between the lateral surface 3012 of cover plate 30 lower hem 301 and medial surface 3011 is that S2, S1 are less than S2.During installation, lateral surface 3012, second side plate 102 that the first side plate 101 is placed in lower hem 301 is placed in the medial surface 3011 of lower hem 301, thus the lower hem 301 of clamping cover plate 30.In this enforcement, the first side plate 101, second side plate 102 and connecting plate 103 one connect, thus improve overall structural stability.
Abutting part 104 is extended to form by the first side plate 101.Particularly, the first side plate 101 is free end relative to one end of connecting plate 103.This free end deviates from the second side plate 102 direction and extends thus form abutting part 104.During installation, this abutting part 104 abuts with the medial surface 201 of Cross beam for plug-in box 20, thus makes shielding finger 10 and Cross beam for plug-in box 20 keep conducting continuity.During for avoiding installing, abutting part 104 scratches Cross beam for plug-in box 20, and abutting part 104 has elasticity.When further avoiding installing, abutting part 104 scratches Cross beam for plug-in box 20, and the free end 1041 of abutting part 104 bends towards the second side plate 102, arranges in cambered surface to make abutting part 104.During installation, the cambered surface projection of abutting part 104 and the medial surface 201 of Cross beam for plug-in box 20 offset, thus realize the conducting continuity of shielding finger 10 and Cross beam for plug-in box 20.
Further, the lower hem 301 for convenience of cover plate 30 inserts the position between the first side plate 101 of shielding finger 10 and the second side plate 102, and the first side plate 101 is that chamfering is arranged with the junction of abutting part 104.
Further, defining the second side plate 102 relative to one end of connecting plate 103 is free end, and this free end deviates from the first side plate 101 and extends to form extension 105.Lower hem 301 for convenience of cover plate 30 inserts the position between the first side plate 101 of shielding finger 10 and the second side plate 102, and the junction of extension 105 and the second side plate 102 is that chamfering is arranged.
Further, for strengthening the bonding strength between shielding finger 10 and cover plate 30, avoid shielding finger 10 to come off from cover plate 30, extension 105 is provided with some hangnails 106.Some hangnails 106 equidistantly distribute along the length direction of extension 105.The end of some hangnails 106 is towards the first side plate 101 direction projection.During installation, the end of hangnail 106 abuts with the medial surface 3011 of the lower hem 301 of cover plate 30, thus improves the bonding strength between shielding finger 10 and cover plate 30, avoids shielding finger 10 to come off from cover plate 30.
Further, for the ease of batch production, user can shear corresponding length according to demand.For the ease of shearing, shielding finger 10 also comprises the sheared edge 107 of some hollow outs.Be provided with a sheared edge 107 between two adjacent hangnails 106, and distance between two adjacent sheared edges 107 is equal.User can arbitrarily according to demand shear from sheared edge 107.Sheared edge 107 is sheared, thus the efficiency of shearing can be improved.
Further, shielding finger 10 also comprises between the adjacent sheared edge 107 of some location holes 108, two and is provided with a location hole 108, and distance between two adjacent location holes 108 is equal.This location hole 108 is banded shielding finger 10 plays location and feeding effect when hardware dies is shaping.
The shielding finger 10 that the utility model provides, the first side plate 101 of this shielding finger 10 and the second side plate 102 clamp the lower hem 301 of cover plate 30, keep conducting continuity to make shielding finger 10 and cover plate 30.The abutting part 104 of this shielding finger 10 abuts with the medial surface 201 of Cross beam for plug-in box 20, to make shielding finger 10 and Cross beam for plug-in box 20 keep conducting continuity, thus ensures that whole electromagnetic-field-shielded body remains conducting continuity.The utility model can not only form effective electromagnetic-field-shielded body, and can improve the life-span of shielding finger 10 use.
These are only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
