Connector device capable of meeting two-way transmission requirement of digital television

Abstract

The invention discloses a connector device capable of meeting two-way transmission requirement of a digital television. A metal sheet wraps a cylindrical copper rod, two ends of the cylindrical copper rod are arranged into two slightly-divided parts, the positions of a center of circle corresponding to the two parts are provided with grooves which are matched with TV signal wires, the grooves areclamping grooves, the metal sheet beyond the cylindrical copper rod is divided into three pieces and are arranged into a fusiform grabhook; or one metal sheet is rolled into a cylinder shape, two ends of the cylindrical metal sheet are arranged into grabhooks with a dumbbell shape with the thin middle part and two thick ends, and the thin part of the dumbbell shape is the clamping groove and is matched with the TV signal wire. The connector device can meet the two-way transmission requirement of the digital television, and has convenient, fast and firm connection, makes pictures clearer and more stable, and has no noise interference.

Description

technical field

[0001] The invention relates to a joint device of a television system, in particular to a joint device capable of meeting the requirements of bidirectional transmission of digital television. Background technique

[0002] The connecting device used in the existing TV receiving system, whether it is wireless satellite or cable, and whether it is analog TV or digital TV, it includes various wired cable connectors, patch cords, branches, distributors, user boxes , set-top boxes, various amplifiers, optical transmitters, receivers, etc., the F connectors and F connectors used have the following disadvantages: the TV signal line single-strand copper wire is twisted on the F head and the connection method is to rely on a thin hole in the product socket. The metal clip is connected by touch, the contact surface is very small, sometimes even the metal clip and the TV signal line are suspended from each other, the TV signal can only be transmitted by induction, and af...

Examples

Embodiment 1

[0012] refer to figure 1 , the present invention consists of a phosphor copper sheet 2 wrapped around a cylindrical copper rod 3, the end of the cylindrical copper rod 3 is divided into two semi-cylinders, in the shape of a slightly opened bell mouth, and the centers of the two semi-cylindrical bodies are arranged symmetrically Slightly thinner than 1 / 2 the groove of the half-strand copper wire of the TV line, the symmetrical grooves form the clamping groove 4, and the part of the phosphor copper sheet 2 beyond the cylindrical copper rod 3 is equally divided into 3 pieces, from the middle of the excess part It is bent into an included angle greater than 90°, and its ends are closed to form a spindle-shaped gripper 1 .

Embodiment 2

[0014] refer to figure 2 , the present invention rolls the phosphor copper sheet 2 into a cylindrical shape, 4-12 holes are arranged at both ends of the cylindrical shape, and a dumbbell-shaped gripper 5 with a thin middle part and thick ends at both ends is arranged, and the hollow part of the dumbbell-shaped detailed part is a clamp Tight groove 4.
