clamping device

Abstract

The invention provides a clamping device. The clamping device comprises a shell, a pressing piece and two clamping pieces. the shell comprises an upper shell and a side shell which are connected witheach other, and one part of the side shell is bulged along a first direction to form a bulged part; The pressing piece moves relative to the shell, the pressing piece comprises a pressing part and twostopping parts, and the vertical projection of the stopping parts on the side shell is located in the protruding part. The clamping piece rotates relative to the shell and comprises two clamping parts and two clamping parts. wherein the clamping part is located above the upper shell, when the pressing part is located at the first position, the position of the stop part is overlapped with the action path of the clamping part, the pressing part is located above the upper shell, and when the pressing part is located at the second position, the position of the stop part is separated from the action path of the clamping part. When the clamping device is in use, the contact part can be shielded by the bulge part, and even if the contact part is abraded, the whole clamping device can be maintained to be attractive because a user cannot see the abraded part.

Description

technical field [0001] The invention relates to the field of printed circuit installation equipment, in particular to a clamping device. Background technique [0002] In recent years, with the development of data centers and clouds, more functions have been added to the servers and storages used in data centers and servers, so that the computing or data access capabilities and speeds can be faster. , so many small cards with different functions are also configured in the server and storage. Small cards are usually connected to the main board in the server or storage through the Peripheral Component Interconnect Express (PCIe) interface, but sometimes due to component configuration or connection interface factors, the small card will first To be fixed on the housing, for example, screws can be used to lock the small card on the housing. However, after the screws are attached to the casing, the screws may protrude from the casing, so that maintenance personnel may be cut by ...

Problems solved by technology

However, after the screws are attached to the casing, the screws may protrude from the casing, so that maintenance personnel may be cut by the protruding screws when performing maintenance. On the other hand, the protruding screws also reduce the overall appearance.

[0003] In this regard, an operable mechanism can also be used to fix the carrier board on the board body. However, if the operable mechanism involves the joint action relationship between multiple components, it may cause wear and tear between the components. , and thus degrades the overall aesthetic
