[0002] In the prior art, cable television, also known as cable TV, is developed from wireless television. Since television signals are transmitted through cables and are not blocked by high buildings or mountains, the viewing quality is good. The cable television network system is a television network system that uses radio frequency cables, optical cables, multi-channel microwave distribution systems or a combination of them to transmit, distribute and exchange sound, image and data signals.

[0003] The cable TV network uses coaxial cables laid by cable TV to transmit data signals. It has the advantages of wide bandwidth, large capacity and low cost. When cable TV is in use, connectors are needed to connect the cables. However, the existing connectors have the following shortcomings when in use: the outward end of the cable TV connector at the end is prone to signal leakage, affecting the signal transmission quality. Utility Model Content

[0004] The utility model aims to provide a cable TV connector signal plug which can be used for a cable TV digital signal output port to prevent signal leakage and improve the cable TV signal transmission quality.

[0005] The purpose of the utility model is achieved as follows: a cable TV connector signal plug, including a connector, the connector is sleeve-shaped, and openings are provided at both the front and rear ends of the connector. A connecting piece is connected to the connector, and a plug is provided at the other end of the connecting piece. A mounting hole is opened on the plug, and the mounting hole coincides with the central axis of the plug. The depth of the mounting hole is less than the height of the plug, an insulating sleeve is provided on the inner wall of the mounting hole, and an external thread is provided on the outer periphery of the plug.

[0006] The plug of the utility model is installed on the cable TV connector through the connecting piece. When the opening of the cable TV connector needs to be blocked, the plug's insertion tube is inserted into the cable TV connector, and the plug is rotated. The clearance between the plug and the second connecting ring provides space for the plug to rotate, so that the external thread of the insertion tube is engaged and fixed with the internal thread of the connector. The back seat of the plug abuts against the end of the connector, and the signal is shielded by the insulating sleeve in the mounting hole. The material of the insulating sleeve is PP (polypropylene T3OS), which avoids signal leakage and improves the quality of cable TV signal transmission. Compared with the prior art, the utility model has the beneficial effect that it can be used for the cable TV digital signal output port, prevents signal leakage, and improves the quality of cable TV signal transmission.
