Cable television cable connection device

A cable television cable connection device belongs to the television signal transmission part technology field. The cable television cable connection device comprises a metal sheet. A near middle part of the metal sheet forms a tubular body. A first gap way is formed at a length direction of the tubular body. One end of the tubular body is extended so as to form a group of card line pieces whose middle parts tends to clamp and the two ends form a bell mouth. The adjacent card line pieces form a card slot. A guiding ring is formed at a tail end of the card line piece. A second gap way is formed at the length direction of the guiding ring. The other end of the tubular body is extended so as to form a stricture tubular body or fixedly connect with a round copper bar. A guiding cable core possesses a good positioning effect. The card line pieces possess a good elastic recovery function. Connection is convenient, rapid and firm. Active equipment can be guaranteed to provide power normally in a network so that a downstream cable television user can watch television. Intrusion of noise and interference can be avoided. A link index of an HFC network can be guaranteed so that the HFC network can operate stably and reliably.
