1. A connecting device comprising:
a riser bracket having a first side wall; a positioning mechanism having a plurality of standoffs and a latch that are disposed on said first side wall, each of said standoffs having a head, a shoulder, and a neck that interconnects said head and said shoulder, said latch being movable relative to said first side wall between a locking position and a releasing position; and a riser card including a card body and an electrical connector that is disposed on said card body, said card body having a plurality of through holes that are slidably and respectively engaged with said standoffs, each of said through holes having a large hole portion for extension of said head of a respective one of said standoffs and a small hole portion that has an inner diameter being equal to an outer diameter of said neck of the respective one of said standoffs, said large hole portion and said small hole portion being arranged to be in communication with each other in a sliding direction; wherein, during assembling of said riser card, moving said riser card in the sliding direction after extension of said heads of said standoffs through said large hole portions of said through holes enables said necks of said standoffs to enter respectively said small hole portions of said through holes, so that a portion of said card body located around said small hole portion of each of said through holes is clamped between said head and said shoulder of a corresponding one of said standoffs, and moving said latch from the releasing position to the locking position prevents said riser card from moving reversely, thereby fixing said riser card. |
