When the third bracket 3 moves toward the cabinet together with the drawer, the first guide rod 23 is first inserted into the first guide hole 13 to guide the second bracket 2 to move relative to the first bracket 1, thereby realizing a one-time guiding function. During this process, the first plug assembly and the second plug assembly are inserted into place to realize connection and fixation. At this time, the connector device reaches the position shown in FIG. Figure 6 In the test position shown, the second bracket 2 is reliably connected to the first bracket 1. At this time, the limiting member 35 and / or the gasket set on the top of the second guide rod 24 in the limiting mechanism prevent the third bracket 3 from moving relative to the second bracket 2. As the drawer continues to move toward the cabinet, the guide members 34 on both sides of the through hole 33 move along the guide grooves 26 on both sides of the second clamping hole 22, and the elastic member 25 in the buffer mechanism is compressed. Under the action of the elastic member 25, the third bracket 3 continues to move toward the cabinet relative to the second bracket 2. At this time, the limiting member 35 and / or the gasket are separated from the top of the second guide hole 32, and the second guide rod 24 passes through the second guide hole 32 and moves in the opposite direction, finally reaching the state shown in FIG. Figure 7 Working position status.
