F型连接器典型用于75Ω电缆分配系统，特别是CATV，广播电视网络，它既可用于有阻抗匹配要求的场合，也可用于非匹配场合。其特点是螺纹连接、插合方便、价格适宜。
F型连接器可与国际上同类产品互换使用。FL10产品为M10X0.75螺纹，结构、性能与F型相同。
F type joining devices use for 75 Ω cable assign system, especially CATV, broadcast television network, It can already be used for h***ing impedance to mate the occasion required, can be used in not mating the occasion too. It is joined, inserts helping jointly that its characteristic is whorl , the price is suitable.
F type joining devices can exchange and use with the similar products in the world. FL10 products are M10X0.75 whorl, the structure, performance are the same as F type.
