Interface extension structure for expanding computer case

Abstract

The invention provides an interface extension structure for expanding a computer case. The interface extension structure comprises a first case component, a second case component, a mainboard and an extension suite, the first machine shell part and the second machine shell part are arranged in a combined mode, the mainboard is arranged in the first machine shell part and provided with an installation position, and an extension distance is formed between the installation position and the second machine shell part so that the extension sleeve part can be arranged. The extension suite comprises an interface circuit board electrically connected with the mainboard, an interface connector arranged on the interface circuit board, and at least one extension piece for supporting the interface circuit board; wherein the second machine shell piece is provided with an opening corresponding to the interface connector, and the extension piece is matched with the extension distance to be arranged at the installation position, so that the interface connector is exposed out of the surface of the second machine shell piece through the opening. The interface extension structure is used in cooperation with the expansion machine shell, and corresponding extension structures can be provided according to different thicknesses so as to meet the requirement for arranging expansion interfaces on the machine shell.

Description

【Technical field】 [0001] The invention relates to a connection interface, in particular to an interface extension structure for expanding a computer case, especially for the interface exposed on the surface of the case. 【Background technique】 [0002] General commercially available notebook computers and other products are usually designed with fixed hardware and specifications when they leave the factory, and can only be expanded within a limited range. However, in order to meet the needs of industrial computers with special specifications, by increasing the distance between the "C part" and "D part" commonly known in the notebook computer industry, the thickness of the shell can be increased to increase its internal space. , and then can expand other electronic components such as batteries, hard disks, etc. [0003] Yet, because aforementioned expansion must increase the thickness of housing, so if want when disposing various expansion interface on the surface of computer...

Problems solved by technology

[0003] Yet, because aforementioned expansion must increase the thickness of housing, so if want when disposing various expansion interface on the surface of computer case, can make the distance between expansion interface and motherboard because of increasing the thickness of housing. With the increase, this is not only a problem of electrical connection, because the space generated in the distance will also affect the impact of the expansion interface under the force of plugging and unplugging, so this design must have a certain strength complementary structure to solve the problem at the same time. Problems such as electrical connection and plugging force caused by distance
