F型連接器典型用于75Ω電纜分配系統，特別是CATV，廣播電視網絡，它既可用于有阻抗匹配要求的場合，也可用于非匹配場合。其特點是螺紋連接、插合方便、價格適宜。

F型連接器可與國際上同類產品互換使用。FL10產品為M10X0.75螺紋，結構、性能與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 having 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.
