A longitudinal groove 13a is formed on the front surface 11a of the insulating body 1a. A plurality of conductive terminals 2a located in the longitudinal grooves 13a are embedded on the rear surface 12a of the insulating body 1a, and are electrically connected with the inserted flexible circuit board 20a. The conductive terminal 2a is roughly "U"-shaped, and includes a top wall 21a, a bottom wall 22a, and welding arms 23a protruding from the insulating body 1a. There is also a pressing plate 3a that can move back and forth, and the pressing plate 3a includes a pushing portion 31a, a fixing portion 32a and hook portions 33a at both ends.
