EXTERNAL EXPANSION DEVICE FOR MAINFRAME COMPUTER EXPANSION CARD

Abstract

An external expansion device for a mainframe computer expansion card, which includes: a L-shaped expansion rack and a data line for connecting with expansion card. The expansion rack is provided outside the mainframe computer chassis. The expansion rack includes a fixed part, and at least one expansion card plug part vertical to the fixed part. The one end of the data line for connecting with expansion card is electrically connected with the expansion card plug part, the other end of the expansion card plug part is used to connect with a motherboard inside the mainframe computer chassis. It does not need to remove the cover of the chassis during the demolition process, so that the purpose of dust-proof is achieved. It has a fast speed to add, remove, and replace the expansion card just in several seconds and is easy to operate without professional operation.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] In order to make the purpose, technical solution and advantages of the disclosure more clearly, the disclosure, combined with drawings and embodiments, will be further detailed. It should be understood that the specific embodiments described herein are intended only to explain the disclosure and are not intended to qualify the disclosure.

[0015] As one aspect of the disclosure, it provides an external expansion device for a mainframe computer expansion card, which includes: a L-shaped expansion rack 1 and a data line 2 for connecting with expansion card. The expansion rack 1 is provided outside the mainframe computer chassis 3. The expansion rack 1 includes a fixed part 4, and at least one expansion card plug part 5 vertical to the fixed part 4. The one end of the data line 2 for connecting with expansion card is electrically connected with the expansion card plug part 5, the other end of the expansion card plug part 5 is used to connect with a motherboard 7 inside the mainframe computer chassis 3.

[0016] Preferably, the expansion rack 1 is connected with the outside of the mainframe computer chassis 3. Preferably, the expansion rack 1 is integratedly shaped with the mainframe computer chassis 3.

[0017] Preferably, the other end of the expansion card plug part 5 is connected with the motherboard 7 by an expansion card 6.

[0018] Please refer to FIG. 3 and FIG. 4, when using, firstly, connect the expansion rack 1 with the motherboard 7 inside the mainframe computer chassis 3 through the data line 2, and put the expansion rack 1 outside the mainframe computer chassis 3. Then, install the cover of the mainframe computer chassis 3 to seal the mainframe computer chassis 3. Next, insert the external expansion card 8 to be installed into expansion card plug part 5 of the expansion rack 1. Thus, the expansion card is installed completely.

[0019] As a result of the above-mentioned technical solution, the disclosure can add, removing, and replace the expansion card outside the mainframe computer chassis without using any tools, removing the cover of the chassis, and turning over the chassis. Therefore, it does not need to remove the cover of the chassis during the demolition process, so that the purpose of dust-proof is achieved. Additionally, it has a fast speed to add, remove, and replace the expansion card just in several seconds and is easy to operate without the need of professional operation.

[0020] The embodiments described above represent only a few embodiments of the disclosure, its description is more specific and detailed, but cannot be understood as a limitation on the scope of the patent of the disclosure. It should be pointed out that for ordinary technical personnel in the art, without departing from the concept of the disclosure, you can also make a number of deformations and improvements, these are the scope of protection of the disclosure. Therefore, the scope of protection of the patent of the disclosure shall be subject to the attached claim.
