A protective cover for a connector is described herein. In one example, the protective cover can include an angled outer shell to envelop a connector, and a locking mechanism to prevent the angled outer shell from retracting to expose the connector. The protective cover can also include a plunger assembly coupled to a magnet, the magnet to disengage the locking mechanism to expose the connector, and a set of springs to return the angled outer shell to a locked position.
