[Prior art]

 CPU execution speeds and efficiencies are becoming increasingly higher, evolving from early Intel's 80386, 80486, Pentium to Pentium Pro, which is now the mainstream in the market. However, since Pentium Pro provides a cache in the CPU to increase the execution speed, the area of the CPU, the number of pins are relatively increased, and the temperature and the defective rate are significantly increased. In order to improve this situation, Intel has abandoned the conventional structure and has designed a completely different type of P6 CPU, which is named Pentium II (PENTIUM II, hereinafter abbreviated as P2).

In P2, one CPU and an external cache are provided on one substrate, the outside thereof is packaged in a PLGA, and the motherboard is connected to a motherboard by a cartridge gold finger connector system. However, the PLGA package processing step of the CPU is cumbersome and time-consuming, and in addition, the cost of the CPU has been increased due to this packaging method. 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 has been sold. Since such a CPU does not require additional PLGA package processing, the delivery time of the CPU can be shortened, but it has a problem in assembly.

The CPU is mounted upright, and the CPU mounting base 10 (see FIG. 1) of the motherboard serves as a support portion for the CPU, and the CPU 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 20 package, respectively, so that the stopper portions 22 can be protruded from both sides of the package or can be built in. At the time of combination, the operation unit 21 is first turned inward to incorporate the stopper 22 into the PLGA package, the CPU 20 is inserted into the CPU mount 10, and then the operation unit 21 is turned outward to turn the stopper 22. By engaging the inside of the stopper hole 11, the CPU 20 can be fixed to the CPU mounting base 10. When attaching the heat radiating piece 30, the heat radiating piece 30 is assembled to the stopper hole 23 provided in the PLGA package by the fastener 40, but since the stopper hole 23 is provided only on one side of the PLGA package, The mounting position is limited, so the engineer must consider the size and area of the heat sink 30 in the circuit layout of the motherboard, and also select the electronic components, which leads to design and production problems. Was brought. Further, since the stop hole 23 is provided on the surface of the PLGA package, the fastener 40 must be provided so as to straddle the heat radiating piece 30, so that the heat radiating piece 30 has no position corresponding to the stop hole 23. The fin zone 31 had to be selected and it had to have a corresponding perforation 32 in this finless zone 31. Otherwise, it is necessary to further improve the structure of the fastener 40, and the types of the fastener 40 and the heat radiation piece 30 that can be used are clearly limited.

[0005]

[Problems to be solved by the invention]

 In view of the fact that there is still no cartridge form suitable for a board-type CPU, and in view of the limitation on assembling of a heat radiating piece provided by a PLGA package, the present invention is a CPU cartridge combining a board-type CPU with A new type of CPU cartridge structure that incorporates the CPU board, heat sink, and fasteners for attaching the heat sink, and allows the heat sinks to be combined regardless of the presence or absence of the finless area and the shape of the fastener. Is an issue.

Next, in the present invention, in the CPU cartridge, an elastic piece is extended on both sides of the cartridge, an operation portion is provided at an upper end of the elastic piece, a hook is provided at an appropriate position on an outer end surface, and the operation portion is provided. A locking piece is provided at the bottom end of the cartridge, and a projection corresponding to the locking piece is provided at the upper end of the cartridge, and the elastic piece is compressed so that the locking piece of the elastic piece engages with the projection of the cartridge. The position of the elastic piece can be fixed so that the engaging portion of the elastic piece of the cartridge is detachably engaged with the stop hole of the CPU mounting base on the motherboard, and the CPU cartridge is attached to and detached from the motherboard. The task is to make it convenient.

[0007] The present invention further provides the above-mentioned CPU cartridge, in which the heat radiating piece is in close contact with the surface of the CPU chip on the CPU board mounted on the cartridge, and heat is directly transmitted to the heat radiating piece to increase the heat radiation efficiency. That is the task.
