Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described, so that those skilled in the art can be better understood from the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
Referring to shown in Fig. 1, Fig. 2, the disclosed a kind of expansion board fixed structure 20 of first embodiment of the invention, for fixing expansion board 10 on circuit board 11.
Circuit board 11 of the present invention, refers to and is applied to the electronic calculator mainboard of PC (PersonalComputer), circuit board etc., and the described expansion board 10 that expansion board 10 is a kind of bus standard connecting electronic calculator mainboard and external equipment.Except expansion board 10, circuit board 11 may also include other and constitutes electronic calculator mainboard, and makes mainboard can completely perform the necessary assembly of function.Those necessary assemblies are that tool usually intellectual can be done by according to the usual knowledge in this area, and the place of non-invention characterizing measures, and its details repeats no more in this.
In first embodiment, circuit board 11 arranges expansion slot 12 and fixing post 13, and, expansion board 10 has apical margin 101 parallel to each other and root edge 102, and root edge 102 arranges an edge connector 120, the edge connector 120 of expansion board 10 is used for being inserted in expansion slot 12, makes expansion board 10 be fixed on circuit board 11.Simultaneously, fixing post 13 and expansion slot 12 are arranged on circuit board 11 distance one extension length 1000, this extension length 1000 is a predetermined dimension length on circuit board 11, need to by conjunction with expansion board fixed structure 20, different size length expansion board 10 can be achieved on the circuit board 11 of another scale lengths the purpose plugged.
Consulting shown in Fig. 1 and Fig. 2, expansion board fixed structure 20 includes clamping piece 21 and a sliding part 22.
The apical margin 101 of one end contact expansion board 10 of clamping piece 21, it is possible to firmly fix expansion board fixed structure 20 on expansion board 10.
Sliding part 22 is slidably joined in the other end of above-mentioned clamping piece 21, and can slide along a glide direction 1200 relative to clamping piece 21.On the contrary, sliding part 22 can slide towards fixing post 13 along glide direction 1200 relative to clamping piece 21.
As shown in Figure 1, Figure 2 with shown in Fig. 3, sliding part 22 sets at least one perforate 200, this perforate 200 can use accommodating fixing post 13, fixes the sliding part 22 position on circuit board 11 by fixing post 13, makes expansion board fixed structure 20 be fixed on circuit board 11.
In a concrete application examples of the present invention, expansion board 10 is M.2 solid state hard disc in PCIe (PeripheralComponentInterconnect-Express) communications protocol.Expansion board 10 can also be display adapter, network interface card, sound card and memory card etc. any can the electronic installation form of coupled circuit plate 11, and be not limited.Further, PCIeM.2 specification district is divided into type2242, type3042, type2260, type2280 and type22110, wherein the width of expansion board 10 is 22mm and 30mm two kinds, and relatively length is divided into 42mm, 60mm, 80mm and 110mm tetra-kinds, this length is the length calculated from fixing post 13 to expansion slot 12.Therefore, refer to shown in Fig. 3, circuit board 11 is intended to the expansion board 10 of installing different size length, its corresponding specification demands, namely circuit board 11 is fixed post 13 and the spacing distance of expansion slot 12, must coordinate above-mentioned scale lengths, and the expansion board fixed structure 20 that the invention discloses, then can coordinate the expansion board 10 of different length.
