Some connectors have a flat, plastic top that sits flush on top of their socket. Often, these connectors have multiple cables connected to them. Flat-topped connectors are usually on the larger side, and are typically used to connect batteries in laptops and larger gaming devices.

Sometimes, these connectors have a slide lock running across the top that holds the connector in place. If this is the case, push the lock away from the connector before trying to disconnect it.

Flat topped connectors can also have a metal locking bar that keeps the connector in place. Unclip and flip the locking bar up to disconnect it.
