Detailed description of the invention
Below with reference to accompanying drawing, detailed description of the invention and embodiment to the present invention are described in detail, and described specific embodiment, only in order to explain the present invention, is not intended to limit the detailed description of the invention of the present invention.
As it is shown in figure 1, Fig. 1 quick detachable radome exploded view before assembling that is the present invention, on smart mobile phone mainboard as a example by the radome shielding BB chip, described quick detachable radome includes weldering frame 110 and the capping 120 of metal of metal；Described capping 120 is used for being fastened on described weldering frame 110 when assembling；Shown in Fig. 2, Fig. 2 is the quick detachable radome of present invention local structural graph after assembling, and described capping 120 is wrapped in the outside of described weldering frame 110, so that the BB chip 100 being positioned at after welding assembly within described weldering frame 110 to play shielding and the effect of auxiliary heat dissipation；Wherein, for the ease of disassembly and assembly, shown in Fig. 3, Fig. 3 is the partial structurtes enlarged drawing of the capping in the quick detachable radome of the present invention, the sidewall 121 of described capping 120 periphery is provided with the line of rabbet joint 123 being communicated to base 122, form the line of rabbet joint 123 of open type, the sidewall 121 of described capping 120 is carried out part segmentation, to reduce the bonding strength of itself and described weldering frame 110；The described line of rabbet joint 123 is longitudinally disposed, and such as, the described line of rabbet joint 123 is rectangular, and the base 122 of the vertical described capping 120 in long limit of the rectangle line of rabbet joint 123 is arranged.
In the preferred implementation of the quick detachable shielding of the present invention, as shown in Figure 1, the described line of rabbet joint 123 can arrange along the lateral separation, base 122 of described capping 120 sidewall 121, to reduce the firmness that described capping 120 is connected with described weldering frame 110 further, it is easier to dismounting.
It is preferred that arrange at equal intervals between multiple lines of rabbet joint 123, the distance between the most adjacent two lines of rabbet joint 123 is equal, and uniformly to weaken the rigidity of described capping 120 sidewall 121, homogenization reduces the bonding strength of itself and described weldering frame 110, it is ensured that fasten quality.
Further, the end face 114 at described weldering frame 110 is also provided with lightening core 115, for alleviating the weight of described weldering frame 110；And, described lightening core 115 can be provided with the connecting portion 116 being connected to each top side wall, for increasing the bulk strength of described weldering frame 110, described connecting portion 116 exceeds the end face 114 of described weldering frame 110 and arranges.
Accordingly, end face 124 in described capping 120 is provided with the rib 126 of adaptive described connecting portion 116, for strengthening the bulk strength of described capping 120, the end face 124 of the outwardly described capping 120 of described rib 126, to contain the connecting portion 116 exceeding described weldering frame 110 end face 114.
Concrete, connecting portion 116 on described weldering frame 110 includes connection strap 116a and 116b of two decussations；Rib 126 in described capping 120 includes that square convex edge 126a and the cross convex edge 126b, the cross convex edge 126b in described capping 120 that arrange on this square convex edge 126a are suitable with connection strap 116a and 116b of two decussations on described weldering frame 110.
Simultaneously, the lightening core 115 of described weldering frame 110 end face 114 may also function as improving further the effect of radome heavy industry performance, the size of the most described lightening core 115 requires more than shielded device such as BB chip 100 size, thus when needing rework, pull down described capping 120, cut off connection strap 116a and 116b on described weldering frame 110, can in the case of need not taking off described weldering frame 110 heavy industry BB chip 100, then after heavy industry, buckle described capping 120 again, and then also the shield effectiveness of radome will not be impacted.
Additionally, in order to improve welding performance, knot is also provided with being communicated to the breach 113 on base 112 on the sidewall 111 of described weldering frame 110 periphery, to coordinate the pad of PCB to increase the contact area with scolding tin, it is simple to climb stannum during welding.
In the preferred implementation that the above capping of the present invention and described weldering frame are fastened and connected, as shown in Figure 1, on the sidewall 121 of described capping 120, lateral separation is arranged with the salient point 127 that multiple inside side is prominent, such as spheric boss point etc., on the sidewall 111 of described weldering frame 110, also lateral separation is arranged with multiple through hole 117, with described salient point 127 one_to_one corresponding, such as corresponding with boss point circular hole etc.；When described capping 120 being fastened on described weldering frame 110, each salient point 127 being positioned on described capping 120 sidewall 121 is buckled in each through hole 117 on corresponding described weldering frame 110 sidewall 111 the most one by one, the reliability being fastened and connected with guarantee.
Shown in Fig. 2, preferably, in order to reduce technology difficulty, reduce production cost, the weldering frame 110 of the capping 120 of metal and metal all can molding by the way of bending, therefore, corner in described capping 120 can arrange technology groove 128, to avoid crossing two side 121 to produce the phenomenon interfered after bending, and, corner at described weldering frame 110 may also set up technology groove 118, to avoid crossing two side 111 to produce the phenomenon interfered after bending, thus avoid and by the way of stretching, described in molding, cover 120 and weld frame 110, the line of rabbet joint in described capping 120 and the breach on described weldering frame 110 all can be completed in its respective first time blanking operation, reduce technology difficulty, save production cost.
Shown in Fig. 3, preferably, salient point on described capping 120 sidewall 121 127 and the described interlaced arrangement of the line of rabbet joint 123, the inhomogeneities that described capping 120 both can have been avoided to be connected with described weldering frame 110, can ensure that again the concordance of described capping 120 sidewall 121 local strength；Concrete, as required 1 described line of rabbet joint 123 can be set every 1～3 described salient point 127.
Compared with radome of the prior art, the quick detachable radome of one provided by the present invention, owing to have employed the two-part construction being fastened and connected, and on the closure sidewall playing shielding action, have employed the line of rabbet joint design of opening, greatly reduce the bonding strength of capping and weldering frame, being easy to when heavy industry carry out disassembly and assembly, to improving, radome heavy industry performance after welding is highly beneficial.
Should be understood that; the foregoing is only presently preferred embodiments of the present invention; it is not sufficient to limit technical scheme; for those of ordinary skills; within the spirit and principles in the present invention; can be increased and decreased according to the above description, replaced, converted or be improved, and all these increase and decrease, replace, convert or improve after technical scheme, all should belong to the protection domain of claims of the present invention.
