The inclined-plane 91 of electric connector 90 has towards the inclined surface 911 of retaining member 81 and 82 (main body 95 1 sides of electric connector) decline up to the direction of FFC 40 insertions.

When the FFC 40 that flat cable joint 80 is installed when inserting electric connector 90 to a certain degree, the most advanced and sophisticated 85a of lock arm 85 abuts against on the inclined-plane 91 of electric connector 90.When FFC 40 further inserted electric connector 90, the inclined surface 911 on inclined-plane 91 caused main body 95 bendings of lock arm 85 beginnings towards electric connector 90.When finishing FFC 40 and insert electric connectors 90, lock arm 85 recovers from its case of bending by elasticity, and lock pawl 851 engagement ramp 91 that becomes, and produces the click sensation of rattling away.Therefore, the operator can rattle away by click and feel to confirm whether FFC 40 inserts electric connector 90 fully.The lock arm 85 of flat cable joint 80 has flexibility.

In order to dismantle FFC 40 from electric connector 90, the most advanced and sophisticated 85a of lock arm 85 presses down towards retaining member 81 and 82 (main body 95 1 sides of electric connector 90).Lock arm 85 is flexible till it abuts against on the main body 95 of electric connector 90, but no longer crooked after on abutting main body 95, this prevents lock arm 85 damages.According to the electric coupler component shown in Figure 11 of first embodiment also have towards flat cable joint 10 extend and with the fastener 313 of retaining member 11 and 12 opposite extensions.But compare with fastener 313, lock arm 85 shown in Figure 19 is not easy to damage more.In addition, in the electric coupler component according to first embodiment, fastener 313 is formed in the electric connector 30 that is welded on the circuit board.Therefore, if fastener 313 damages, electric connector 30 must be dismantled from the circuit board that is welded with electric connector 30, so that change fastener 313, this is loaded down with trivial details.On the other hand, in electric coupler component,, only need to change flat cable joint 80 even lock arm 85 damages according to the 4th embodiment.As long as flat cable joint 80 does not need welding, the replacing of lock arm 85 will be more prone to.

Described each embodiment although be installed in the situation of substrate surface with reference to electric connector, the electric connector that constitutes according to electric coupler component of the present invention is not limited to this.
