Layer includes the first sticking part, along the rake that extends downwardly out of right part of the first sticking part, along the right part level of rake
The second sticking part extending to the right；Described first sticking part is arranged on the lower surface of described copper cash, described second sticking part,
Formation one receiving space is enclosed between the lower surface of rake and described copper cash；Described stiffening plate is arranged on described receiving space
Interior.Because stiffening plate itself is high temperature resistant, under hot conditions, hardness is also harder, directly supports copper cash, prevents copper cash from sinking；Under
Layer the second insulation glue-line is class zigzag, when strong extruding copper cash contact head, pressure is dispersed in the stiffening plate of lower section
On, stiffening plate has downtrend, and now, rake can provide pull-back forces to support stiffening plate, so effectively prevents
In FFC, copper cash occurs sinking under the high temperature conditions.
2nd, stiffening plate of the present utility model by PET and coat PET outer surface on polyester hot-melt adhesive be prepared from.Institute
State the weight of PET and polyester hot-melt adhesive than for 1：2, improve that it is high temperature resistant further, ageing-resistant.
