Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.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.
As shown in Figure 3 and Figure 4, a kind of turn-break type screening cover that the utility model embodiment provides, for being hidden by the electric elements of electronic product inside, the interfere with electromagnetic field produced when working to prevent electric elements affects the reliability that Total Product uses to outdiffusion.This screening cover comprises lid 11; the both sides that lid 11 is relative are bent to form the container cavity (not indicating in figure) for holding electric elements in the same way; during installation; electric elements are arranged in container cavity the covering that can realize electric elements, also serve the function of protective device element simultaneously.And in order to realize the electrical connection with other electron component, lid 11 is provided with and accesses for flexible PCB 20 the connection breach 12 carrying out with electric elements being connected, during connection, one end of flexible PCB 20 is accessed by this connection breach 12, convenient and swift.
When actual production is assembled, because of the needs of paster SMT (surface mounting technology) technique, screening cover need be prevented to be distorted in paster SMT process, to be out of shape and to produce the problem of paster bad hidden danger, thus screening cover must ensure good integral planar degree, and higher high temperature ability of anti-deformation.As shown in Figures 3 to 6, in the present embodiment, in order to overcome the low defect of screening cover structural strength, the opening part connecting breach 12 is provided with the support arm 13 for strengthening lid 11 structural strength, the two ends of this support arm 13 are connected on the two side of connection breach 12, the opening connecting breach 12 is connected, thus serve the function strengthening overall construction intensity, ensure that overall flatness, in the middle of the process of paster SMT, whole screening cover can not deform, and reaches good consistency, improves the qualification rate of paster.And according to the matching requirements of reality, after completing paster, if this support arm 13 exists always, but interference is created to assembling, thus after completing paster, need this support arm 13 to remove, to prevent from, in the middle of the process used, occurring that support arm 13 is by the problem of flexible PCB 20 scratch.In the present embodiment, conveniently support arm 13 is removed, support arm 13 is provided with can after flexible PCB 20 accesses, just self can be twisted off and come off with lid 11, structure 14 is twisted off with what prevent its scratch flexible PCB 20, structure 14 is twisted off by this, just can be simple, safe twists off removal by this support arm 13, and damage can not be caused to lid 11, after removing simultaneously, as shown in Figure 7, other component is not had in whole connection breach 12, eliminate the potential safety hazard of scratch flexible PCB 20, ensure that the fail safe that flexible PCB 20 uses.
A kind of screening cover turn-break type screening cover that the utility model provides, by being provided with support arm 13 in the connection breach 12 on lid 11, thus improve the structural strength of screening cover entirety, can not there is deformation in screening cover in paster process, support screening cover and keep good flatness, ensure that the consistency of paster.Meanwhile, twist off structure 14 by being provided with at the two ends of support arm 13, thus after paster completes, support arm 13 can be twisted off removal, ensure that support arm 13 can not disturb assembling, also can not scratch flexible PCB 20, eliminate potential safety hazard.By such setting, achieve the ability of anti-deformation of screening cover when can ensure paster, after paster, support arm 13 can be twisted off again, reach the technique effect eliminating quality hidden danger, and do not increase the technology difficulty of screening cover, reach the effect made the best of both worlds.
Particularly, as shown in Figure 4, in the middle of specific design, lid 11 can be an overall structure, also can be the structure that a decentralized photo coordinates.When as a whole structure, the connection breach 12 for accessing for flexible PCB 20 can be opened in the sidewall of lid.And in the present embodiment, the conveniently access of flexible PCB 20, is arranged to comprise upper cover 111 and lower cover 112 by lid 11, and connects breach 12 and be arranged on lower cover 112.During assembling, upper cover 111 is covered at lower cover 112, make that the end face of lower cover 112 is covered is sealed to a complete face, connect breach 12 on the sidewall of lower cover 112, meanwhile, the position of upper cover 111 correspondence is also provided with an empty avoiding district, thus can not stop interference flexible PCB 20.
Particularly, as shown in Figure 5 and Figure 6, in the present embodiment, this twists off structure 14 for being arranged on the stamped recess on support arm 13 two ends.Like this, the stamped recess formed on support arm 13 by the mode of punching press, is lessened the thickness at support arm 13 two ends, thus is convenient to twist off.Further, the two ends of support arm 13 do not cut off with the connection be connected between breach 12 sidewall by this stamped recess completely, and structural strength herein can maintain the flatness of screening cover entirety, meets the demand of paster.
Particularly, when actual setting, according to actual processing, can be that only this stamped recess is set in the one side of support arm 13, and in the present embodiment, as shown in Figure 8, for improving the convenience twisted off, being just provided with on the lateral surface that support arm 13 liang is relative and twisting off structure 14, thus under the prerequisite ensureing structural strength, reduce further the thickness at support arm 13 two ends, thus be convenient to twist off.
Preferably, this cross section twisting off structure 14 is obtained in " trapezoidal " vertically to twist off the length direction of structure 14.In other embodiments, the shape of cross section in the direction in which in " arc " can also be arranged to by twisting off structure 14.Certainly, can also be other shape, only need ensure to play the function strengthening structural strength, also be convenient to twist off, do not limit at this.
Concrete, as shown in Figure 9, also can be set to be arranged on support arm 13 two ends and the tear line that combines of the break-make mouth 141 on through support arm 13 two sides relatively by multiple by twisting off structure 14.Each break-make mouth 141 interval is arranged, thus both ensure that overall structural strength, and conveniently twists off removal.
Particularly, when specifically arranging, first the two ends of support arm 13 can also be provided with groove, and the relative lateral surface of support arm 13 liang is provided with this groove, then tear line is arranged at the bottom of groove, further increase the convenience twisted off.
The utility model additionally provides a kind of electronic product, comprises above-mentioned screening cover turn-break type screening cover.Because above-mentioned screening cover is provided with support arm 13, overall structural strength can be ensured when paster, can not be out of shape, thus ensure that the consistency of paster.And be provided with and twist off structure 14, after paster, support arm 13 can be removed, just can eliminate the interference of support arm 13, ensure that the quality of electronic product complete machine.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace or improvement etc., all should be included within protection range of the present utility model.
