Bus module and server

A server, comprising:

• a case, wherein a slot is formed in one side of the case;
• and
• a bus module configured to be plugged into the slot, comprising:
• a housing, having a first end and a second end opposite the first end;
• a second connector, connected to the first end of the housing, and configured to be plugged with a first connector arranged in the slot;
• a bus network interface card, arranged in the housing, wherein the bus network interface card comprises a network interface card body and a blocking piece, the blocking piece is connected to one end of the network interface card body away from the second connector, a first bending portion is formed at one end of the blocking piece, the first bending portion extends in a direction away from the network interface card body, and a first shielding portion arranged around the first bending portion is formed at a position on the housing corresponding to the first bending portion;
• and
• a lever structure, comprising a hinge end, an operating end, and a second bending portion, wherein the hinge end is hinged to one side of the second end away from the first bending portion, the second bending portion is connected to the operating end, the second bending portion is configured to be in contact with the first shielding portion and is detachably connected to the first shielding portion;
• wherein the hinge end is provided with a first abutting protrusion and a second abutting protrusion, wherein the first abutting protrusion is configured to contact and press a notch of the slot when the operating end rotates in a direction away from the housing, so as to remove the bus module from the slot, and wherein the second abutting protrusion is configured to engage a contact slot formed in a slot wall of the slot when the second bending portion is connected to the first shielding portion, so as to prevent the bus module from being removed from the slot, and to disengage the contact slot when the operating end rotates in the direction away from the housing, so as to allow the bus module to be removed from the slot.
