The utility model proposes a kind of shielding constructions 100, applied to the pcb board 200 of mobile terminal, mainly to do each mould Isolating and protecting between block, anti-stop signal interfere with each other.

Referring to Fig.1 and 2, the shielding construction 100 includes: screen in 100 1 embodiment of the utility model shielding construction Lid 10 is covered, including cover board 11 and the side plate 13 extended from 11 edge of cover board towards side bending, bending place offers at least two and allows Position hole 111；With shield clip 30, it is installed on the plate face of pcb board 200, and is correspondingly arranged with relief hole 111.Shield clip 30 is held on Side plate 13, and shield clip 30 deviates from the end accommodation of pcb board 200 in relief hole 111.

Specifically, the material of screening cover 10 is metal material, and shape is consistent with the shape with screened circuit, optional Ground, screening cover 10 are rectangular metal lid.Generally, which is including the cover board 11 and by covering by stamping forming 11 edge of plate vertically bends the side plate 13 of extension towards side, can so reduce the gap of 13 junction of cover board 11 and side plate.Screen Covering folder 30 towards the surface of pcb board 200 is that welding plane is generally welded by surface mounting technology (SMT) technique securely In in the plate face of pcb board 200.Shield clip 30 is held on side plate 13 so that screening cover 10 to be fixed on pcb board 200, meanwhile, shielding Folder 30 deviates from the end accommodation of pcb board 200 in relief hole 111.So setting, the non-shielded folder 30 of the height of screening cover 10 Height limitation, height can be effectively reduced, and greatly reduce entire screening cover 10 occupies volume, so that mobile Terminal is more light and small, promotes user experience effect.

Accordingly, it is to be understood that, the technical solution of the utility model, by shielding in setting on the pcb board 200 of mobile terminal Shield structure 100, so that obtaining effective isolating and protecting between each module, and then anti-stop signal interferes with each other.The shielding construction 100 Including screening cover 10 and set on the shield clip 30 of pcb board 200, screening cover 10 includes cover board 11 and from 11 edge of cover board towards side The side plate 13 extended is bent, and its bending place offers relief hole 111；Shield clip 30 is held on side plate 13, and shield clip 30 is carried on the back End accommodation from pcb board 200 is in relief hole 111.So setting, the height of screening cover 10 is no longer by 30 height of shield clip Limitation, height can be effectively reduced, so that mobile terminal is more light and small, promote user experience effect.Meanwhile It is simpler effectively to may make the assembly and disassembly of shielding construction 100, also, in assembling process, can be clearly observed Screening cover 10 slides into shield clip 30, to be more convenient for judging whether screening cover 10 is held in place.

In order to further reduce the height of screening cover 10, clamping part 33 away from the mounting portion 31 end accommodation in allowing In the hole 111 of position, and protrude from the outer surface of cover board 11.It should be understood that since the height of screening cover 10 has obtained effective drop Low, shield clip 30 can protrude from the outer surface of cover board 11 away from the end of pcb board 200.In this way, screening cover 10 can be further decreased Occupy volume so that mobile terminal is further light and small, further promote user experience.

Referring to Fig. 2 and Fig. 3, shield clip 30 includes mounting portion 31 and at least two clamping parts set on mounting portion 31 33, mounting portion 31 is installed on the surface of pcb board 200；Relief hole 111 includes at least two sub- relief hole 111a, two sub- relief holes 111a is correspondingly arranged with two clamping parts 33 respectively；Two clamping parts 33 are held on side plate 13, and each clamping part 33 is away from installation The end accommodation in portion 31 is in a relief hole 111.

Specifically, the mounting portion 31 of shield clip 30 is smooth welding plane, and clamping part 33 is clamp structure, shield clip 30 Both ends respectively have a smooth welding plane, at least one welding plane between two fixtures is strong with enhancing assembling bonding Degree, mounting portion 31 (namely three smooth welding planes) are welded in pcb board by surface mounting technology (SMT) technique securely In 200 plate face；Each clamping part 33 (namely clamp structure) of shield clip 30 is held on side plate 13, and screening cover 10 is fixed On pcb board 200, meanwhile, clamping part 33 deviates from the end accommodation of mounting portion 31 in relief hole 111.

In an embodiment of the utility model, side plate 13 offers resigning breach 131 away from the side of cover board 11, steps down Notch 131 is correspondingly arranged with shield clip 30, and mounting portion 31 is placed in the resigning breach 131.

Specifically, the shape of resigning breach 131 can be rectangle, trapezoidal or other reasonable shapes.Resigning breach 131 Setting, can guarantee that the side plate 13 for not opening up resigning breach 131 is connected to the surface of pcb board 200 completely.Resigning breach 131, The mounting portion 31 of shield clip 30 and the corresponding setting of relief hole 111, shield clip 30 accommodates in resigning breach 131, clamping part 33 It is held on the side plate 13 of neighbouring resigning breach 131, and clamping part 33 is just placed in relief hole 111 away from the end of mounting portion 31 It is interior.

Further, shield clip 30 is provided with multiple, multiple being provided at circumferentially spaced along screening cover 10 of shield clip 30；It steps down Hole 111 is provided with multiple, and every two relief hole 111 is correspondingly arranged with two clamping parts 33 of a shield clip 30 respectively；Each shielding Folder 30 is held on side plate 13, and each shield clip 30 deviates from the end accommodation of pcb board 200 in a relief hole 111.Multiple screens It covers folder 30 and multiple relief holes 111 is correspondingly arranged, may make that the periphery of screening cover 10 can be gripped, thus into one Step reinforces the installation stability of screening cover 10.

Similarly, resigning breach 131 is also equipped with multiple, and each resigning breach 131 is correspondingly arranged with a shield clip 30, often The mounting portion 31 of one shield clip 30 is placed in resigning breach 131, and the side plate 13 for being not provided with resigning breach 131 is then connected to The plate face of PCB so can play the role of preferable isolating and protecting to the circuit module on pcb board 200.

Referring to Fig. 1 and Fig. 2, in an embodiment of the utility model, screening cover 10 further includes being connected to side plate 13 mounting lug 15, mounting lug 15 offer the first mounting hole 151；Pcb board 200 offers right with the first mounting hole 151 The second mounting hole 210 answered；Screening cover 10 is fixed by the cooperation of fastener and the first mounting hole 151 and the second mounting hole 210 In pcb board 200.

Specifically, mounting lug 15 is usually and is bent by side plate 13 to obtain outwardly, and the surface of mounting lug 15 is in parallel simultaneously It is connected to the plate face of PCB.The middle part of mounting lug 15 offers the first mounting hole 151, and pcb board 200 offers and first peace Fill corresponding second mounting hole 210 in hole 151, the second mounting hole 210 is generally threaded hole, and fastener is generally screw, screw according to It is secondary to be plugged in the first mounting hole 151 and the second mounting hole 210, it can realize being fixedly connected for screening cover 10 and pcb board 200. The setting of mounting lug 15 can further enhance the installation stability of screening cover 10.

In order to further enhance the installation stability of screening cover 10, mounting lug 15 is provided at least two, described in two 15 Relative distribution of mounting lug is in the two sides of the screening cover 10.Optionally, the shape of screening cover 10 is rectangular-shape, is installed convex Ear 15 is arranged adjacent to the four corners of screening cover 10, operation can be so easily installed, moreover, the production of mounting lug 15 is more square Just.
