Interface card insertion and removal device

The present invention provides an interface card insertion and removal device, in particular, an interface card side assembly driving mechanism, which is driven forward and backward by the driving mechanism to drive the positioning plate and the interface card of the driving mechanism to be displaced up and down, so that the interface card is performed by the side of the chassis. Plug and unplug, to achieve the purpose of the interface card is easy to move and remove in the chassis.

According to the trend of network cloud technology, PC and server technologies are growing at an ever-changing speed. The development trend of PCs and servers is mainly toward the direction of computing power, speed and small size. The rack-mounting space of the rack server is such that the server chassis can be moved and stored, and the server units are connected to each other to generate a multiplex of the server. Therefore, the entire device servo system can be regarded as A large cabinet.

At present, the height of the server chassis is divided into four specifications: 1U, 2U, 3U, and 4U. The so-called U (unit) is used to define the height of a cabinet unit. The width of a 1U cabinet is 19 inches. It is 4.445cm, and the width of 2U is also 19 inches, and its height is 8.89cm. The specifications are the same. Therefore, the server can be selected according to the specifications of the uniform size space. The chassis is used for application, and most operators will install most server chassis together in a larger electrical cabinet. Internally, it is convenient for the management and maintenance of the server. However, when the interface card or hard disk installed in the server is to be inserted, removed, or replaced, the cover panel of the chassis must be disassembled. In order to allow the interface cards and hard disks to be inserted and removed vertically and vertically, it is not only troublesome for inserting and unloading interface cards or hard disks, but also easy to be subjected to various servers in the periphery of the electrical cabinet during actual operation. If the cover panel of the server chassis cannot be removed directly in the electrical cabinet, the server enclosure cover panel must be removed before the server is removed from the electrical cabinet for plugging and unplugging the interface card. After the replacement, the cover panel is covered on the server again, and then the server is reinstalled into the electrical cabinet. The operation is quite time-consuming, labor-intensive and inconvenient, and the operator must think about how to space in the limited space of the electrical cabinet. To reduce the difficulty of disassembly and replacement of the interface card or hard disk inside the multiple server chassis. If you can design the server without taking the server out of the electrical cabinet, you can directly interface the card or hard. It can effectively reduce the insertion, removal, maintenance or maintenance of electronic components (such as interface cards, hard disks, etc.) and connection interfaces in various chassis when it is plugged and unloaded, and has the effect of easier maintenance and replacement. The speed and cost are the key to the research and improvement of those who are still in the industry.

Therefore, in view of the problems and shortcomings in the quick disassembly and assembly of the above-mentioned conventional chassis panels, the new creators have collected and reviewed relevant materials through multi-party evaluation and consideration, and have continuously tried and modified the years of research and development experience in this industry. A new patent for the interface card insertion device was born.

The positioning member 237 can be used to position the substrate 23 and the positioning plate 21, and the positioning plate 21 is restricted by the limiting guide groove 236, so that the substrate 23 and the interface card 1 driven by the substrate 23 are only vertically displaced.

Please refer to the second, third, fourth, fifth, sixth, seventh and eighth figures, as shown in the figure. It is clear that when the interface card 1 and the driving mechanism 2 are horizontally displaced into the socket 301 of the chassis 3 and displaced into the insertion space 30, the substrate 23 slides along each of the guide grooves 310 of the inner frame 31, and the positioning plate 21 is slid. The positioning guide pins 215 are slid into the limit rails 33 of the chassis 3, and the docking side 11 of the interface card 1 does not correspond to the state of the electrical connector 321 . The positioning guide pins 215 are limited to the limit rails. 33. When the interface card 1 and the driving mechanism 2 are inserted into the predetermined position, the docking side 11 of the interface card 1 has been in the state of the electrical connector 321 , and the positioning guide pin 215 is displaced out of the limit rail 33, and the transition can be utilized. The hooking hole 2210 of the handle 22 is driven by an external force, that is, the driving and pushing member 22 is translated back and forth at the holding groove 235 of the substrate 23, and one of the pushing members 22 is located at one or more of the substrate 23 with the upper limit slot 220.

When the guide pin 215 is restricted by the limit slide rail 33, the positioning plate 21 cannot be driven. When the interface card 1 and the driving mechanism 2 are inserted into the predetermined position (the state in which the docking side 11 of the interface card 1 has been corresponding to the electrical connector 321), the positioning guide pin 215 is disengaged from the limiting slide rail 33, and the positioning plate 21 can be moved downward. In addition, the damage of the docking side 11 can be prevented from being damaged, and the purpose of protecting the docking side 11 can be achieved; and the card board 212 of the positioning board 21 is not inserted into the predetermined position when the interface card 1 and the driving mechanism 2 are not inserted. The locking slot 312 of the chassis 3 is removed from the inner frame 31 when the card 212 is moved down. When the interface card 1 and the driving mechanism 2 are inserted into the predetermined position, the card 212 can be moved down. By inserting the locking groove 312, damage to the collision of the butt side 11 can be avoided, and the purpose of protecting the butting side 11 can also be achieved.

When the interface card 1 inside the chassis 3 is inserted, removed, or repaired, the external cover panel outside the chassis 3 is not required to be disassembled, and the drive mechanism 2 can be used to complete the insertion and removal of the interface card 1, which can save the province.
