A connector has a casing and a circuit board structure. The circuit board structure is mounted through the casing and has a board main body, a projecting body, and multiple metal electrodes. The projecting body is mounted on a connecting end surface of the board main body and projects from the connecting end surface in an insertion direction of the connector. When the connector is connected to another device, the projecting body of the circuit board structure may push a part of pins of the device first, so the user may exert less force to insert the projecting body into the device. Then, when the circuit board structure is inserted further, the board main body may abut the remaining pins. Because part of the pins have been pushed away by the projecting body, the board main body only needs to counteract resistance from the remaining pins.
