Embodiment
To clearly reveal spirit of the present utility model with graphic and detailed description below, those skilled in the art are after understanding preferred embodiment of the present utility model, can be by the technology of the utility model institute teaching, change and modification, it does not break away from spirit of the present utility model and scope.
Fig. 1 to Fig. 4 is the stereogram shown in each visual angle of an embodiment in the circuit board retention mechanism of the present utility model.As shown in Figures 1 to 4, circuit board retention mechanism of the present utility model comprises a base portion 100, a rake 110 and a sliding component 200.
Fig. 5 is the fastening schematic diagram of circuit board retention mechanism.As shown in Figure 5, circuit board retention mechanism of the present utility model is installed in the position in the casing 900, the position of the circuit board 902 that its corresponding desire is fastening and installing.When desire is inserted into circuit board 902 slot 901 in the casing 900 that is equiped with circuit board retention mechanism of the present utility model, sliding component 200 is positioned at the lower position of the rake 110 of base portion 100 earlier, be preferably placed at the extreme lower position of rake 110, make the fastening part 220 of sliding component 200 wider space be arranged, be convenient to the operation that circuit board 902 inserts slot 901 to fastening direction.At this moment, sliding component 200 is not to be in the state that fixture 210 is fixed, and just, sliding component 200 can be along rake 110 slippages of base portion 100.Then, after circuit board 902 insertion slots 901, make sliding component 200 along rake 110 to higher position slippage, when the fastening part 220 of sliding component 200 is butted on circuit board 902, by the fixing relative position of sliding component 200 and base portion 100 of fixture 210, then circuit board 902 is because fastening part 220 fastening can't be withdrawed from slot 901 to the rightabout that inserts slot 901, thereby circuit board 902 can firmly be inserted in slot 901 and keep excellent electrical property to connect.When desire removes slot 901 with circuit board 902 under this state, as long as can simply circuit board 902 be removed slot 901 with the reverse procedure of above-mentioned steps.
In technological thought scope of the present utility model, can carry out application implementation miscellaneous, for example, no matter sliding component 200 shown in Fig. 1 to Fig. 4 stops at the optional position of rake 110, fastening part 220 all is parallel to the bottom surface of base portion 100, and one side that is parallel to the fastening circuit board of desire, if but the circuit board that supports when casing and the desire signature of installing circuit board retention mechanism of the present utility model is not when being parallel situation, as shown in Figure 6, also can adopt fastening part 220 with circular arc camber, the fastening part (not shown) that perhaps has projection is with the fastening circuit board of the mode of one or more contacts.For the fastening part 220 of avoiding circuit board and hard is damaged the fastening part that also can apply liner (not shown) or adopt soft material on fastening part 220 because of unexpected the impact.Base portion 100 shown in Fig. 1 to Fig. 4 is structures of three place's complications, and the side of first groove 118 and base portion 100 almost vertically is provided with; But as shown in Figure 7, consider circuit board retention mechanism of the present utility model the saving that position, material cost are set, produce the factors such as shortening in man-hour, thereby the base portion 100 and the design of sliding component 200 are simplified, resulting circuit board retention mechanism feature also is contained in this case claim, can bring about the desired effect.In addition, take the stably fastening circuit board in the fastening part 220 that dwindles fastening area into account, can not skid off fastening part 220 because of accidents such as vibrations make circuit board, one recess 221 can be set on the fastening part, recess 221 preferably extends with the direction that is parallel to circuit board, it is fastening that circuit board is embedded recess 221 ground, avoids circuit board to skid off fastening part 220 thus.The above embodiments are that example describes with the part with respect to the sliding component 200 of base portion 100 bottom surface directions as fastening part 220 all, but in conjunction with the situations such as position that are provided with of the space in the casing, circuit board retention mechanism, the arbitrary portion of sliding component 200 all can be used as fastening part 220.Suchlike application implementation also is interpreted as being contained in the claim of the present utility model.
By the foregoing description as can be known, as use circuit board retention mechanism of the present utility model, the circuit board module that can will be inserted in the casing inside of desktop PC, server etc. firmly is anchored in the slot, keeps excellent electrical property and connects.
Though disclosed several embodiment of the present utility model as mentioned above; right its is not in order to limit the utility model; any those skilled in the art are not in breaking away from spirit and scope of the present utility model; can do various changes and retouching, therefore protection range of the present utility model should be as the criterion with subsidiary claim.
