Embodiment
Please with reference to Fig. 1.The buckle structure 100 that the utility model provides is used for sub-circuit board 30 is fixed in main circuit board 10.One of sub-circuit board 30 end is plugged in the connector 11 be located on the main circuit board 10 to realize being electrically connected with main circuit board 10.The other end of sub-circuit board 30 is provided with at least one location hole 31, is used for cooperating with buckle structure 100, thereby is positioned main circuit board 10.In this execution mode, sub-circuit board 30 is a wireless network card.
Please with reference to Fig. 2.Buckle structure 100 comprises operating portion 23 and at least one locking part 20.Each locking part 20 comprises elastic portion 21 and clamping part 22.Elastic portion 21 is through being fixedly welded on main circuit board 10.Clamping part 22 own elasticity portions 21 are towards extending away from the direction of said main circuit board 10 and cooperating sub-circuit board 30 is fastened in said locking part 20 with the location hole 31 of said sub-circuit board 30.Thereby said operating portion 23 is connected in the elastic portion 21 of said at least one locking part 20 makes said clamping part 22 withdraw from said location hole 31 to drive elastic portion 21 generation strains.
In this execution mode, buckle structure 100 comprises a pair of locking part 20, and correspondingly, said sub-circuit board 30 comprises a pair of location hole 31, cooperates so that said sub-circuit board 30 firmly is positioned main circuit board 10 with said locking part 20 respectively.
In this execution mode, clamping part 22 comprises support chip 221, trip 222 and spacer 223.Support chip 221 is used to support said sub-circuit board 30 between said elastic portion 21 and said spacer 223.Said spacer 223 is located between said trip 222 and the said elastic portion 21.
Please be simultaneously with reference to Fig. 3 and Fig. 4.During installation, said trip 222 is aimed at the location hole 31 of said sub-circuit board 30.Push sub-circuit board 30; Make trip 222 pass the location hole 31 of said sub-circuit board 30 and be fastened in the surface of said sub-circuit board 30; Spacer 223 is contained in the location hole 31 of sub-circuit board 30 and is held in wall within the said location hole 31; Said support chip 221 supports said sub-circuit board 30, thereby sub-circuit board 30 is positioned main circuit board 10.
