Technical Field
The invention relates to the field of PCIE card mounting structures, in particular to a PCIE card fixing device.
Background
A PCIE card generally refers to a function expansion card or a switch card inserted into a PCIE interface. Is a new generation of bus interface. Compared with PCI and earlier shared parallel architecture of computer bus, each device has its own dedicated connection, and does not need to request bandwidth from the whole bus, and can raise data transmission rate to a very high frequency, so as to reach high bandwidth which can not be provided by PCI.
The traditional installation of PCIE card in the chassis is fixed through fixed support, especially when a plurality of PCIE cards are installed simultaneously, the PCIE card slides and inserts the casing to fix the sheet metal component of PCIE card outer end and the sheet metal component in the chassis through the screw, as shown in figure 1. However, the screws in the multiple PCIE card structures are cumbersome to disassemble and assemble and need tools such as a screwdriver, which brings inconvenience to practical use.

Connect the buckle and can fix closing device on the casing to realize detachable connection, compress tightly the side and be connected with PCIE card and compress tightly fixedly to it, the slip side then can realize compressing tightly the slip of closing device on the casing under the state, conveniently connect the connection of buckle and casing.
Preferably, the sliding side is provided with a support arm. When the pressing side applies pressure to the PCIE card, the pressing device inevitably receives a reaction force and tends to deflect, the supporting arm is used for propping against the shell and supporting the pressing device, and otherwise, the pressing device reduces the pressing force due to deflection.
Preferably, the support arm is U-shaped, one end of the support arm is connected with the pressing device body, the shell comprises a support plate, and the support plate is located in an opening of the U-shaped support arm. The support arm can support each other between a plurality of angles and backup pad through the U-shaped structure, further improves closing device and installs the stability on the casing.

The first spout of slip buckle cooperation is used, improves closing device's installation stability, installs through the second spout during the installation.
Preferably, the first sliding groove is arranged on one of the shell or the pressing device, and the other sliding groove is provided with a sliding convex strip matched with the first sliding groove. The connection distance of slip sand grip and first spout is longer, and the stability of structure is better.
Preferably, the pressing side is provided with at least one pressing protrusion along the length direction. The pressing bulge is used for pressing the sheet metal part on the PCIE card.
Preferably, a connecting buckle handle is arranged at the tail end of the extending direction of the connecting buckle. The connecting buckle handle is convenient to pull the connecting buckle to separate the connecting buckle from the fixed clamping groove.
Preferably, one end of the sliding buckle opposite to the extending direction is provided with a sliding buckle handle. The sliding buckle handle can be pressed to separate the sliding buckle from the second sliding groove in a lever mode.
The invention has the following beneficial effects:
1. the pressing device is detachably connected with the shell, so that the PCIE card is fixed and is convenient to disassemble and assemble;
2. the pressing device is fixed at multiple positions, so that the stability of installation of the PCIE card on the shell can be ensured;
3. the connecting buckle and the sliding buckle are both provided with handles, so that the operation is convenient.
