[Prior art]

 The Pentium II has one CPU and an external cache on one board, and the outside of the board is connected to the motherboard in the form of a PLGA package and a cartridge gold finger connector. However, the PLGA packaging step of the CPU is cumbersome and time consuming, and the packaging method has increased the price of the CPU. As a result, computer manufacturers not only had to wait for the delivery of CPUs, but also lost the business opportunity because they could not lower the selling price of computers and increase their competitiveness in the market. In order to improve such a situation, a board-type CPU without a PLGA package, that is, a CPU board has been sold. This type of CPU does not require additional PLGA package processing, so that the delivery time of the CPU can be shortened, but has a problem in assembly.

The CPU of the PLGA package is mounted upright, and the CPU mounting base 10 (see FIG. 1) of the motherboard is used as a support portion for the CPU 20, and the CPU 20 is fixed. Stop holes 11 are provided at appropriate positions on both sides of the CPU mounting base 10, respectively. Operation portions 21 operable inward and outward are provided on both sides of the upper end of the CPU, so that the stopping portions 22 are protruded from both sides of the CPU or can be built in. When the CPU 20 is inserted into the CPU mounting base 10, when the stop portion 22 reaches the position of the stop hole 11 due to the restriction of the CPU mounting base 10, it is engaged with the stop hole 11 by elasticity. Fixed to 10. When attaching the heat radiating piece 30, the heat radiating piece 30 is attached to the stopper hole 23 provided in the CPU with the fastener 40. It needs to be built in and taken out. However, no locking member is provided on the no-package type CPU board without the PLGA package, and the thickness is much thinner than the PLGA package. It could not be attached, and the radiating piece 30 could not be attached with the fastener 40. Therefore, there has been a demand for a CPU mounting base suitable for mounting a no-package type CPU board and a heat radiation piece. If realized, it would be possible to mount the CPU package on a no-package type CPU board without any packaging, thereby reducing the manufacturing cost and the manufacturing time of the CPU.

【Example】

 As shown in FIGS. 2 and 3, the present invention includes a mounting base 50, which is composed of a fixing plate 51 and a pedestal 52, wherein holes 521 are provided on both sides of the pedestal 52. Are provided at both ends of the slot A of the motherboard with mounting parts 523, and form mounting racks 524 on both sides of the slot A. The elastic piece 511 is extended, and an inclined piece 512 is provided at an upper end of the elastic piece 511. A first stopper 513 is formed inside the elastic piece 511 of the inclined piece 512, and a second stopper 514 is formed at an outer bottom end. An inclined surface 515 corresponding to the inclination angle of the inclined piece 512 is formed at the upper end of the fixed plate 51, and a reinforcing piece 516 is provided on the inner surface of the fixed plate 51 in order to strengthen the support strength of the fixed plate 51. I have.

The present invention further includes a CPU board 60, which includes a CPU chip 61 (not shown in the figure) and a gold finger 62, and a holding member 70 between the heat dissipation piece 80 and the auxiliary piece 90. It is sandwiched.

The present invention further includes the heat dissipating piece 80, which covers the surface of the CPU chip 61, and has two mutually symmetrical openings 81 formed on both sides thereof to form two stop pieces 82. A slope 83 having an appropriate angle is formed on an edge of each of the stopper pieces 82.

The present invention further includes the auxiliary piece 90, which covers the back surface of the CPU board 60 and distributes the holding force of the holding device 70 to prevent the CPU board 60 from being damaged by directly holding the CPU board 60. I do.

At the time of assembling, the heat radiating piece 80, the CPU board 60 and the auxiliary piece 90 are held by the holding member 70 to form one combined body. Then, when this combined body is directly inserted into the slot A, the first stopper 513 is formed. When the gold finger 62 is inserted into the slot A when the elastic piece 511 is obstructed and moves outward, the first stopper 513 is placed on the stopper 82. Thus, the combination of the CPU board 60, the heat radiating piece 80 and the auxiliary piece 90 is fixed in the two mounts 50 (see FIGS. 2 and 4).

After the CPU board 60 is combined with the mounting base 50, the CPU chip 61 has a certain height, so that there is one gap after the heat radiating piece 80 is covered, and the CPU chip 61 is provided on the heat radiating piece 80. The stopper piece 82 is inserted into a mounting frame 524 provided on the pedestal 52. Thus, the left and right sides of the heat radiating piece 80 receive the elastic piece 511, the upper and lower ends are fixed to the first stopper 513, the front and rear both sides are fixed to the mounting frame 524, and the heat radiating piece 80 is stably and firmly fixed. It is fixed in one of the mounting bases 50, so that displacement, detachment from the holding member 70, and unstable swing after the insertion of the gold finger 62 do not occur.

Further, as shown in FIG. 6, when the combined body is removed from the mounting table 50, the inclined piece 512 is turned outward to rotate the second stopper 514 of the inclined piece 512 and the inclined surface 515 at the upper end of the fixing plate 51. When the position of the elastic piece 511 is fixed, the first stopper 513 separates from the stoppers 82 on both sides of the heat radiating piece 80. Therefore, if the user merely pulls the combination upward, the slot is removed. The combination can be taken out from A, and it is not necessary to simultaneously operate the inclined pieces 512 with fingers, so that the combination can be conveniently taken out easily and quickly.
