Connector installation self-buckling structure

The invention discloses a connector installation self-buckling structure which comprises an upper cover and a lower shell, a plurality of bayonets are formed in the peripheral side of an opening of the upper cover, clamping blocks matched with the bayonets to achieve buckling are arranged on the peripheral side of an opening of the lower shell, and the outer surfaces of the clamping blocks are arranged to be arc surfaces. When a product is buckled and assembled, the attached arc surface of the upper cover is clamped downwards, the situation that the outer supporting force is too large due to excessive clamping of corners is avoided, the risk that the upper cover is cracked due to supporting when the four corners are pressed downwards in the assembling process is avoided, and the yield in actual production is 100%; in the downward pressing process, due to the fact that no corner is excessively rotated in the middle, the phenomenon that one corner of a product is not pressed in and is clamped and deformed is av
