Description
Technical Field
[0001] The utility model relates to a cantilever structure used for a mechanical brake booster. Background Art
[0002] A connector is a device used to establish a current or signal connection between two active devices. Connectors are widely used. Among them, a connector for a mechanical brake booster is usually provided with a shell and a locking assembly. The shell is provided with terminals and an inner cavity for installing the terminals. The adjustment assembly includes a swing arm and a follower with transmission cooperation. The movement of the follower is formed by the swing arm, and the connector corresponding to the connector and the follower are linked to cooperate with each other, so that the follower moves when the swing arm swings, driving the connector to be plugged in and out with the corresponding connector. However, the connector used for mechanical brake boosters in the prior art lacks a limiting structure in its adjustment assembly, so that the swing arm and the follower often swing before being plugged in and out with the corresponding connector, which is easy to cause bumps and damage when the two connectors are subsequently plugged in.
