In order to realize the above purpose, the utility model discloses an exempt from welding formula FPC connector, including gluing core, a plurality of interval arrangement setting terminal piece in gluing the core, glue and be provided with the grafting chamber on the core, the one end of terminal piece have the first contact arm that bends of extension in the grafting intracavity, and be provided with the contact point on the first contact arm that bends, the inner wall in contact point and grafting chamber between be formed with first grafting space, the other end of terminal piece have the second contact arm that bends of extension outside gluing the core, and the second is bent and is formed with second grafting space between contact arm and the gluey core.
The beneficial effect of above-mentioned structure is: a first inserting space which is inserted with the flat cable is formed between the first bending contact arm of the terminal piece and the inner wall of the rubber core, a second inserting space which is inserted with the substrate is formed at the upper end of the second bending contact arm of the terminal piece and the upper end of the rubber core, and the FPC connector is convenient to install the flat cable and the substrate by adopting an inserting type connecting structure design. Therefore, the FPC connector has the advantages of simple structure, compact structure, stable and reliable performance, reliable connection and convenient and fast assembly.
Particularly, the two sides of the terminal piece are respectively provided with a limiting block, the rubber core is provided with a limiting groove corresponding to the limiting block, and the limiting blocks are clamped in the limiting grooves and form clamping fit of the terminal piece and the rubber core. The terminal piece is provided with a limiting block clamped with the rubber core, so that the connection between the terminal piece and the rubber core is more compact, and the terminal piece is not easy to loosen and fall off.
Particularly, two ends of the rubber core are respectively provided with a fixing lug, and the fixing lugs are provided with fixing holes. Be provided with fixed ear on gluing the core, be provided with the fixed orifices on the fixed ear to the installation of this FPC connector of being convenient for, it is more convenient to install.
Particularly, the insertion cavity of the rubber core is provided with grooves corresponding to the first bending contact arms of the terminal pieces, and the tail parts of the first bending contact arms are provided with bending guide arms extending in the grooves. The bending guide arm is inserted in the groove of the rubber core, and the bending guide arm can guide the flat cable, so that the flat cable is conveniently connected with the FPC connector.
