Problems solved by technology
[0002] At present, the common cable TV connectors on the market have problems such as unreliable connection, poor electrical performance, too much reflection, and cannot meet the national standard requirements during use, which makes the picture definition of cable TV obviously unable to meet the actual use. need
[0003] Therefore, it is particularly important to design a connector for the single-hole system output port of the cable TV system, and to overcome the reflection problem caused by the sudden change in the size of the inner and outer conductors by overcoming the above-mentioned defects in the prior art, and to improve the transmission performance of the cable TV system.

The invention relates to a cable television system single-hole system output port connector which is characterized by comprising a guide insulator, a shell, an inserting core, a fixing insulator and a crown spring. The guide insulator is installed on the shell in a way of being matched with the F-head internal hole of the shell in an interference mode. The inserting core is installed on the fixing insulator in a way of being pressed in the internal hole of the fixing insulator. The fixing insulator equipped with the inserting core is installed on the shell in a way of being pressed in the fixing insulator installing hole of the shell. The crown spring is clamped on the shell by the clamp spring lower end surface and the clamp spring upper end surface of the shell. The advantages are that 1) unidirectional installation connection is simple, convenient firm and rapid; 2) the fixing insulator is installed at the 9.52 type female head side so that the characteristic impedance of the connector and a connected cable is ensured to be consistent; and 3) reflection caused by step capacitance is low so that reflection in transmission of radio frequency signals can be effectively reduced.
