Embodiment Construction

[0009] The invention comprises an input and output joint (1) of a cable TV terminal branch distributor, a plastic insulating fixing part (3) in the joint, a full-range head nut (6) of the joint on the TV signal line and a single-strand copper wire of the TV signal line (5). The branch distribution input and output connector (1) is fully cut and a matching terminal (2) is set inside the plastic insulating fixing part (3) of the connector, and the central part of the upper plane of the terminal (2) is processed more than 1 deep Reach the screw hole (2-2) in the lower part of the terminal, and the extra holes are spare holes, so that there is room for maneuver in the installation. In the center of the outward end of the terminal (2), process a piece perpendicular to the end surface to reach the screw hole. The channel hole (2-1) of (2-2) is matched with the single-strand copper wire (5) of the TV signal line. The inward end (2-4) of the binding post (2) is welded with the circui...

Abstract

Special points are: The input / output ports of the branch distributor (BD) use plugs with whole teeth. A connection pole (CP) resides in the plug plastic fixing part. There is more than one screw hole (SH) on the CP up plane. Reaching SH and holding the TV cable, a hole is at the center of one CP end and is vertical with the end face. After the cable inserts the hole, cap-less screws press it tightly. Another end of CP is soldered with the input / output of BD circuit. The advantages: (1) Connect solidly to ensure the current to flow freely and a good receiving effect without TV signal decaying. (2) Install fast. (3) Due to using more than one screw and the whole head-sealed screw-cap with several holes or nicks, there is much room during installation. The shield effect is perfect without signal leakage. (4) can turn down brightness to save energy but still bright enough. (5) Connection not loosen easily; not easy to oxidize; thunder proof and saves material and manpower.

Description

Technical field: [0001] The invention relates to a cable TV accessory, in particular to a novel connection device between a cable TV terminal branch distributor and a TV signal line. Background technique: [0002] At present, the connection between the cable TV terminal branch distributor and the TV signal line is to insert the single-strand copper wire of the TV signal line joint into the metal clip of the input and output joint of the branch distributor and tighten the nut to fix it. Such a connection method: first, the contact area is small, resulting in large resistance, small current, and large attenuation of the TV signal; The length of the secant line is difficult to grasp, and it is easy to break off if it is short. It is cumbersome and inconvenient to wait. Invention content: [0003] The purpose of the present invention is to disclose a connection device for a branch distributor of a cable TV terminal and a TV signal line which is firm in connection, does not a...
