Substrate mounted flexible circuit board connector
The present application provides a connection device and a connector. The connector comprises a housing mounted on a circuit substrate and a plurality of terminals. The housing has a recessed region and a plurality of channels. The recessed region, together with the circuit substrate, forms a mating groove for mating a flexible circuit board, and the mating groove extends forwardly to a radius. The plurality of terminals correspond to the plurality of channels and each of the terminal includes a resilient contact arm. The resilient contact arm extends toward a surface of the circuit substrate in the corresponding channel of the housing and extends into the recessed region to form a contact portion. The connection device comprises the circuit substrate and the connector.
