During installation, the second plug-in connector The connector 21 can be plug-fitted with the first plug connector 11 along the first direction 1 and the cover 2 are detachably connected, and the disassembly and assembly process is simple and fast without tools, thereby improving the efficiency of operation, maintenance or replacement of internal parts of the server.

Regarding the structures of the first clamping member 12 and the second clamping member 22, in this embodiment, the second clamping member 22 has a plate-like structure, and the first clamping member 12 includes an elastic part 121 and a stopper part 122. The stopper 122 can move between a release position that is separated from the cover 2 and a locking position that stops the second clamping member 22 from moving away from the box body 1 . The elastic portion 121 is used to stop the stopper 122 in the locking position. .

In the above arrangement, the second clamping member 22 and the cover 2 are integrally formed. The thickness of the second clamping member 22 is smaller than the thickness of the cover 2 . A groove is provided on the side of the cover 2 that cooperates with the stopper 122 . The bottom of the groove and the other side of the cover 2 form a second clamping connection. Item 22. Among them, the setting of the groove also serves as a mark to remind the staff to click here.

Optionally, the box body 1 is provided with a bottom sheet 17. When the second snap-in member 22 cooperates with the first snap-in member 12, one side of the second snap-in member 22 matches the stopper 122, and the other side matches the bottom sheet. 17, the stopper 122 is used to stop the second clamping member 22 from moving away from the box body 1, and the bottom sheet 17 is used to stop the second clamping member 22 from approaching the components inside the box body 1. Of course, in other implementations of this embodiment, when the second clamping member 22 and the first clamping member 12 cooperate, the second clamping member 22 can directly contact the box body 1 .

Specifically, the elastic part 121 has a long strip structure and generates elastic force when the elastic part 121 is bent. One end of the elastic part 121 is provided with a mounting part 123. The mounting part 123 is provided with a mounting hole. The box body 1 is provided with a mounting pin 13. The mounting pin 13 is provided with a screw hole 131 , the mounting pin 13 passes through the mounting hole, and the mounting screw is screwed into the screw hole 131 ; the stop portion 122 is provided at the other end of the elastic portion 121 . Among them, the elastic part 121 is made of plastic material or steel material. With the arrangement of the above structure, the first clamping member 12 has a simple structure, is easy to manufacture, and has low cost. Of course, in other implementations of this embodiment, the elastic part 121 can be a spring. In this implementation, the stopper 122 is slidably provided on the box body 1 , and the two ends of the spring respectively abut the stopper 122 and the box body. 1. Considering the simplicity and cost of the structure, in this embodiment, the elastic part 121 with a strip-shaped structure is preferred.

Since the elastic part 121 has a strip structure, when the elastic part 121 deforms too much, the connection with the mounting part 123 may break.

To this end, in this embodiment, the chassis further includes a stopper 14 , which is provided on the box body 1 and is located between the mounting part 123 and the stopper 122 to limit the bending range of the elastic part 121 . With the above arrangement, when the elastic part 121 is bent to a certain extent, it will contact the stopper 14. At this time, the elastic part 121 from the stopper 14 to the mounting part 123 will not continue to deform, preventing the elastic part from being deformed. 121 is broken at the connection with the mounting part 123. At this time, the elastic portion 121 can continue to undergo elastic deformation from the part between the stopper 14 and the stopper 122. Since the range in which elastic deformation can occur becomes smaller, at this time, a greater force is required to urge the elastic portion 121. The deformation occurs, thereby giving the operator a feedback that the operation is in place, and also preventing the elastic part 121 from breaking at the stopper 14 .

Regarding the structure of the stopper 14, in this embodiment, specifically, the elastic part 121 is provided with a stop groove 1211, and the stop groove 1211 is located between the mounting part 123 and the stop part 122. The chassis also includes a stopper 14, The stopper 14 includes a connecting piece 141 and a stopping piece 142 located at one end of the connecting piece 141 . The connecting piece 141 passes through the stopping groove 1211 , and the stopping piece 142 is located on the side of the elastic portion 121 away from the cover 2 . The connecting piece 141 and the stopper piece 142 are L-shaped. Optionally, the area of the stop groove 1211 is larger than the area of the stop piece 142. When installing, first pass the stop piece 142 of the stop member 14 through the stop groove 1211, and then move the first clamping member 12 to connect The piece 141 is in contact with the side wall of the stop groove 1211. In this state, when the elastic part 121 undergoes a certain deformation, it will be in contact with the stop piece 142. On the one hand, the above arrangement can act as a stopper for the elastic part 121. On the other hand, it also facilitates the installation of the first clamping member 12 and improves the installation efficiency.

In order to improve the assembly efficiency of the cover 2 and the box body 1 , in this embodiment, the stopper 122 is provided with a guide slope 1221 , and the guide slope 1221 is inclined toward the cover 2 in a direction approaching the box body 1 . With the help of the guide slope 1221, when installing the cover 2, insert the second connector 21 of the cover 2 into the first connector 11 and directly squeeze it toward the box body 1 to complete the second connector. The clamping member 22 and the first clamping member 12 are connected. Specifically, during the contact process between the second clamping member 22 and the guide slope 1221, the stopper 122 in the locking position will be pressed in a direction away from the first clamping member 12 until it reaches the release position. At this time, the second clamping member The component 22 will bypass the stopper 122 and fit with the bottom sheet 17, and then under the action of the elastic part 121, the stopper 122 will automatically return to the locking position to complete the snap connection.

In this embodiment, the first clamping member 12 further includes a holding portion 124 . The holding portion 124 is provided at an end of the stopper 122 away from the elastic portion 121 and is bent toward the cover 2 . With the arrangement of the holding portion 124 , it is convenient to grasp the stop portion 122 with your hand and move it away from the cover 2 .

The first plug-in piece 11 includes a first plug-in piece 111 and a second plug-in piece 112. The first plug-in piece 111 and the second plug-in piece 112 are formed into plug slots. The second plug-in piece 21 has a plate-like structure. And can be plugged into the plug slot. Among them, the plug-in piece can be welded or integrally formed with the box body 1 . In this embodiment, the structure of the second plug connector 21 may be similar to that of the second clamping member 22, except that each of the two sides of the cover 2 is connected to the first plug piece 111 or the second plug piece. A groove is provided at the contact position of 112. The structure of the groove can assist in marking and remind the staff to plug in here.

Among them, there are at least two first plug-in pieces 111 and at least two second plug-in pieces 112.

The plug connector 21 can deform to a certain extent to adapt to the twisted plug slot formed by the tolerance of the first plug piece 111 and the second plug piece 112 .

In the second embodiment, the side of the second plug-in piece 112 close to the first plug-in piece 111 is provided with a slope, and the width of the plug slot first remains unchanged and then increases along the opening direction. This arrangement allows the second clamping member 22 to be tilted when mated with the insertion slot, thereby improving the convenience of operation. The angle between the inclined surface and the plane formed by the first direction X and the second direction Y is 10 degrees to 15 degrees.

In the third embodiment, the first plug-in pieces 111 and the second plug-in pieces 112 are arranged staggeredly, and the second plug-in piece 112 is provided with a slope on a side close to the first plug-in piece 111. The width of the plug slot is Along the opening direction, it remains unchanged at first and then increases.
