Abstract
The utility model discloses a shield part combined structure, which comprises a main board, pads, a first shield part and a second shield part. The pads are arranged on the main board. The first shield part and the second shield part are welded on the main board through the pads. Welded pins at the joint of the first shield part and the second shield part are distributed on the same welding line alternately. A pad group consisting of single pads is arranged at the joint of the first shield part and the second shield part. Compared with the prior art, the integral large shield member is demounted into a plurality of shield parts on the premise of constant space, the flatness of each shield part is well controlled, and two or more than two shield parts are welded on the main board in a seamless manner. On the intersection surface, the welded pins of the two shield parts are welded on the main board alternately and arranged on the pads of the same welding line. Space for the main board is saved. Besides, the shield part combined structure is high in reliability, simple in structure and easy to realize.
Description
Technical field
The utility model relates to a kind of cell phone mainboard shielding part device, particularly relates to a kind of combination shielding part structure.
Background technology
In the prior art, the mainboard of mobile phone is provided with pad, and shielding part is welded on the mainboard through pad; Common welding manner is like Fig. 7, shown in 8; Described shielding part structure comprises mainboard 1, and mainboard 1 is provided with pad 2, and shielding part 1 is welded on the mainboard through pad with shielding part 24; But there is the gap between existing structure two shielding parts, causes the space on the mainboard to fail fully to be used.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art; A kind of combination shielding part structure is provided; A complete shielding part is split as a plurality of little shielding part combinations under the situation of space invariance, can better controls, make things convenient for the SMT paster the flatness of shielding part; Simple in structure, be easy to realize.
In order to achieve the above object; The technical scheme that the utility model adopts is: a kind of combination shielding part structure; Comprise mainboard, be arranged at the pad on the mainboard; Be welded on shielding part one and shielding part two on the mainboard through pad, described shielding part one and shielding part are welded on the above the leg interlaced arrangement of shielding part one and shielding part two junctions of mainboard on same bonding wire.
Further, described shielding part one is provided with the pad group that row are made up of single pad with shielding part two junctions.
Compared with prior art, the beneficial effect of the utility model is: whole big shielding part is split as a plurality of little shielding parts under the situation of space invariance, makes the flatness of shielding part be controlled better; And two or more shielding parts are seamless to be welded on the mainboard, is handing on the cross section, and two shielding part leg zigzag welds are connected on the pad of mainboard; Saved the mainboard space; Reliability is high, and simple in structure, is easy to realize.

Embodiment
Be elaborated with reference to accompanying drawing below in conjunction with embodiment, so that the technical characterictic and the advantage of the utility model are carried out more deep annotation.
Like Fig. 1, shown in 2, a kind of combination shielding part structure comprises mainboard 1, is arranged at the pad 2 on the mainboard 1, is welded on shielding part 1 and shielding part 24 on the mainboard 1 through pad 2.Shielding part 1 and shielding part 24 are welded on the mainboard 1.
Like Fig. 3,4,5, shown in 6, further, leg interlaced arrangement on same bonding wire of described shielding part 1 and shielding part 24 junctions.
Further, described shielding part 1 only need be provided with the pad group that row are made up of single pad 2 with shielding part 24 junctions.
The utility model is compared with Fig. 7,8, compares this structure, the shielding part configuration saves mainboard space of the utility model; Compare with the single shielding part of large tracts of land, this kind version is equivalent to a big shielding part is split a plurality of little shielding parts under the situation of space invariance, and the flatness of shielding part can better be controlled like this; Two or above shielding part is seamless is welded on the mainboard, handing on the cross section, will be originally independently two assembly welding dishes change an assembly welding dish into, two shielding part leg zigzag welds are connected on the pad of mainboard.Saved the mainboard space, reliability is high, and simple in structure, is easy to realize.
The content of mentioning in the foregoing description is not to be the qualification to the utility model, and under the prerequisite of the utility model design that does not break away from the utility model, any conspicuous replacement is all within the protection range of the utility model.
