Please refer to FIGS. 7-13, which show schematic diagrams of the installation process of the board holder, a first board 3 and a second board 4, wherein the first board 3 is implemented as a printed circuit board, and the second board 4 When implemented, it is a circuit board with an M.2 solid state drive. When assembling, the assembler of the assembly plant first aligns the fixing structure 15 of the positioning member 1 with the plate hole 31 of the first plate 3 and inserts it (shown in FIG. 7), so that the fixing block of the pin 15 The piece 152 passes through the plate hole 31, and then the plate holder is rotated to make the locking tab 153a of one of the pair of elastic wings 153 move along the top surface of the first plate 3 until It falls into a preset limiting hole 32 on one side of the plate hole 31 to form a locking type that is buckled and cannot be rotated (shown in FIGS. 8 and 9).

Then, insert a contact portion 41 at one end of the second plate 4 into a connector 33 on the first plate 3; move a positioning recess 42 at the other end down and place it in the buckling groove 23 (Shown in Figure 10 and Figure 11). At this time, the assembler moves the toggle lever 24 in a counterclockwise direction to move the opposing buckling groove 23 in a clockwise direction, so that the positioning recess 42 of the second plate 4 is along the upright 161 The lower guiding inclined surface 162 of the top surface moves down and enters the supporting recess 16, and the hook 212 of the fastener 2 is snapped into the slot 122 of the positioning component 1 for the second The plate 4 forms the locking configuration, and the pressing piece 231 above the buckling groove 23 presses the second plate 4 (see FIGS. 12 and 13), so that the plate holder is fixed to the first plate 3, and allow the second plate 4 to form a stable positioning effect, except that it will not shake, and can ensure the electrical connection between the second plate 4 and the connector 33.

To release the locking type of the fixing structure 15 and the first plate 3, the user only needs to hold the unlocking handle 153b, and pull it upwards, so that the locking tab 153a comes out of the limiting hole 32 , To form an unlock pattern. At this time, the user can rotate the plate holder until the fixing baffle 152 is aligned with the plate hole 31, and then the plate holder can be pulled up to separate the plate holder from the first plate 3.

Therefore, through the implementation of this case, the gain effect is that the plate holder uses a fixing structure at the bottom to insert into a plate hole of a first plate, and then is fixed to the first plate by rotating and snapping. , So that the fixing structure will not rotate in the plate hole, so that the plate holder is not easy to shake, and can be applied to the first plate with different plate thickness. Furthermore, the installation and separation of the board holder and the first board are all performed above the first board, which is convenient for users to operate. In particular, the plate holder uses a special pivoting mechanism, such as the quick installation of the pivot and the shaft hole corresponding to the guide slope, which can effectively reduce the manufacturing cost, thereby achieving the advantages of reducing manpower and man-hours. It is comparable One of the most beautiful things you have never seen before.

The disclosure in this case is one of the preferred embodiments, and any partial changes or modifications that are derived from the technical ideas of the case and can be easily inferred by those who are familiar with the art do not deviate from the scope of the patent right of the case.
