A connector includes a housing and a release button. The housing defines a recess for receiving a latch member of a receptacle. The release button is operable to cause displacement of the latch member from the recess and has a surface that aligns with a surface portion of the housing when disconnected from the receptacle. The surface of the release button protrudes from the surface portion of the housing when the connector is connected to the receptacle to provide a visual indication that the connector is connected to the receptacle.

A connector with a built-in substrate includes a chain terminal including a chain portion, a first tab portion configured to protrude from the chain portion in a predetermined direction, a second tab portion configured to protrude from the chain portion in a direction different from a protrusion direction of the first tab portion; an inner housing in which the chain terminal is installed such that the first tab portion and the second tab portion protrude; and a substrate connected to the second tab portion protruding from the inner housing.

An edge connector includes a first row of golden fingers and a second row of golden fingers. The first row of golden fingers is adjacent to a plugging end of the edge connector, and the second row of golden fingers is adjacent to the first row of golden fingers. In a plugging direction of the edge connector, each golden finger in the first row of golden fingers has a first end proximate to the plugging end and a second end opposite to the first end. A first end of a grounded golden finger in the first row of golden fingers is protruded from other golden fingers, and second ends of two or more than two golden fingers in the first row of golden fingers are not aligned with each other.
