Abstract

The utility model relates to a connector narrowing the width of a circuit board, and the connector is composed of a plastic body, a plurality of terminals, a shell body and a concave groove which is inwards arranged on the rear end surface of the plastic body; the terminals are embedded in the plastic body; the shell body consists of a bearing cavity to be in inosculation sleeved on the plastic body. A grounding pin is arranged in a radically bent manner at the rear part of the shell body and is projected between the both-side walls of the bearing cavity of the shell body. When grounding pins are embedded in the plastic body, the grounding pins go through the concave groove correspondingly and respectively; therefore, the width of the circuit board set by the connector is less than or equal to the width of the both-side walls of the shell body to reduce the volume of the product. The utility model ensures the width of the circuit board set by the connector less than or equal to the width of the both-side walls of the shell body and reduces the volume of the product.
