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

The jockey of cable TV terminal branch distributor and television signal line

Technical field:

The present invention relates to the cable TV accessory, the specifically a kind of novel cable TV terminal branch distributor and the jockey of television signal line.

Background technology:

Current cable terminal branch distributor and being connected of television signal line are the single strand of copper wire of TV signal wire terminal to be inserted in the metal intermediate plate of branch distributor input and output joint fastening nut fix.Such method of attachment: the one, contact area is little, causes resistance big, and electric current is little, and the TV signal decay is big; The 2nd, connect insecurely, loosening easily oxidation causes TV image fuzzy, snowflake and reticulate pattern; The 3rd, to install sometimes temporarily, secant length be difficult for to be grasped, and has lacked easily to take off disconnectedly, and when having grown outer nut and tightening, the single strand of copper wire bending is impaired, and runs into nut easily, causes short circuit etc.; The 4th, shield badly, cause leakage signal, tipping is loaded down with trivial details inconvenience etc. again.

Summary of the invention:

The objective of the invention is to disclose a kind of being connected firmly, TV signal is unattenuated, and view reception effect is good, the cable TV terminal branch distributor quick and easy for installation and the jockey of television signal line.

Jockey of the present invention comprises branch distributor input and output joint, be configured in the plastics fixed insulation spare in the joint, the television signal line single strand of copper wire, the television signal line collar nut, it is characterized in that: the inside of driving full tooth joint and the plastic insulation fixture in joint in the branch distributor input and output, a copper binding post is set, at the screwed screw hole that deeply reach binding post middle and lower part of plane processing more than 1 on the binding post, one termination of binding post and the input and output head on the branch distributor circuit board are welded as a whole, one of other end end surface central authorities processing is vertical with end face, lead to screw hole, access opening with television signal line single strand of copper wire coupling, in addition at 3/4 breach with top connection length wideer slightly of the top of branch distributor joint processing than screw hole, the omnidistance end socket nut of TV signal wire terminal is the limit with envelope full marks branch distributor joint, and at the not coplanar of the omnidistance end socket nut of television signal line, diverse location is opened more than 1 and with the hole or the breach of non-cap screw rod coupling needs is installed for circling round.

Use when installing, the single strand of copper wire of television signal line is inserted in the access opening of binding post, the omnidistance end socket nut of the TV signal of circling round wire terminal, hole or breach on the nut are aimed at the wherein hole on the binding post, screwed on non-cap screw rod, circle round omnidistance end socket nut shielding screw hole and breach again.

The advantage of the jockey of this wiring pillar is: be connected firmly, can not become flexible, shielding quick for installation is complete.The room for maneuver is big.Therefore, TV signal is unattenuated, and reception is good, and, clear picture clear as sound, picture are true to nature; The 2nd, because of the screw hole chain of rings on the binding post, open hole more than 1 or breach on the omnidistance end socket nut of television signal line on the diverse location of Different Plane, convenient and swift during installation, possible to make changes, not loaded down with trivial details, because of contacting, brightness and then can be turned down, energy-conservation source is difficult for becoming flexible in addition, is difficult for oxidation thereby reach, not only save material, also can be anti-lightning strike.

Fig. 1 is the enlarged diagram of binding post of the present invention;

Fig. 2 is binding post rigging position of the present invention and television signal line schematic diagram.

Embodiment:

The present invention includes the input and output joint (1) of cable TV terminal branch distributor, the plastic insulation fixture (3) in this joint, omnidistance end socket nut (6) of television signal line top connection and television signal line single strand of copper wire (5).Finger assignments input and output joint (1) is opened full tooth and in the inside of the plastic insulation fixture (3) of joint a binding post that is complementary (2) is set, the last plane central part processing of binding post (2) reaches the screw hole (2-2) of binding post middle and lower part deeply more than 1, wherein unnecessary several be standby hole, make the room for maneuver is installed, in binding post (2) end face central authorities outwardly, process one vertical with end face, sensible screw hole (2-2) and access opening (2-1) television signal line single strand of copper wire (5) coupling.Circuit input and output head welding on the end (2-4) that binding post (2) is inside and the circuit board of branch distributor; One 3/4 of upper top processing at the full tooth joints of finger assignments input and output (1) is long with top connection, is slightly wider than the breach (4) of non-cap screw rod (2-3), and the screw hole (2-2) of binding post (2) is displayed.Diverse location on the not coplanar of the omnidistance end socket nut of TV signal wire terminal is opened hole or the breach that mates with non-cap screw rod more than 1, passes for non-cap screw rod (2-3), and non-cap screw rod and screw hole coupling are equipped.

During use, the insertion access opening (2-1) that the single strand of copper wire (5) of television signal line is inserted binding post (2) the omnidistance end socket nut of television signal line (6) that circles round makes a hole on the nut aim at the wherein hole on the binding post, screws non-cap screw rod (2-3) and tightly suppresses television signal line single strand of copper wire (5) the conditioning signal line end socket nut that circles round again and shield breach (4) and non-cap screw hole (2-2).
