Embodiment

See also Figure 1 and Figure 2, electric connector of the present utility model includes insulating body 1, its central part is provided with terminal slots 11, and both sides are equipped with protuberance 12, plural lower fixed hole 13 and latching device 14, wherein, be installed with plural terminals 2 in this terminal slots 11, each terminal 2 all has contact site 21 and pressure contact portion 22, and this latching device 14 is to include holder 141, press section 142 and trip 143;

Flexible flat cable 3 is to coat the structure that complex lead constituted by insulating barrier, and it is simultaneously gone up in end and forms the plural contact 31 that exposes, and respectively convexes with lug 32 in dual-side;

Locating piece 4, can from top to bottom cooperate and be assembled on the insulating body 1, it has a depression platform 41, platform 41 the place aheads are provided with a stopper section 42, both sides respectively are provided with a groove 43 in caving in, with respect to locating of aforementioned dielectric body 1 protuberance 12 and lower fixed hole 13, be provided with corresponding breach 43 and go up fixing hole 45;

Metal top cover 5 is to cover to be overlying on the locating piece 4 and with insulating body 1 formation to interfix, and its both sides are provided with the stator 51 of plural number with respect to aforementioned upper and

lower fixing hole
