Description

Technical Field

[0001] The utility model relates to the technical field of wires, in particular to a video cable with a connector pressing function. Background Art

[0002] A video cable is a coaxial cable used to transmit analog video baseband signals. Video cables typically have impedances of 75 ohms and 50 ohms, and are categorized by thickness, such as -3, -5, -7, and -9. Video cables generally refer to television cables, but they can also be used for surveillance cameras in security settings. Problems with video cables can lead to signal degradation, mismatches, and device desynchronization.

[0003] In actual use, the above problem is caused not only by the poor quality of the video cable itself, but also by the stability of its connector. Existing video cables use standard plug-in connectors, but their poor tensile and pull-out resistance when subjected to external forces can easily cause the plug to come out, affecting usage.

[0004] The patent with application number CN202322199561.6 and publication (announcement) number CN220731916U discloses a video cable with a connector clamping function, which can fix the video cable through a clamping seat. However, the above patent has the following disadvantages: additional components are required to achieve clamping, which not only increases the occupied space but also is not easy to operate; the end of the video cable is usually hard metal, and a good anti-torsion effect cannot be achieved by simple extrusion; in summary, there is room for improvement. Utility Model Content

[0005] The utility model aims to solve the technical problem of poor firmness of the joints of the video cable in the prior art, and provides a video cable with a joint pressing function.

[0006] In order to solve the above technical problems, the utility model provides a technical solution: a video cable with a connector pressing function, comprising a line 1 and a line 2; the line 1 and the line 2 are provided with connectors 1 and 2 at opposite ends respectively;

[0007] A connecting structure is provided between the first and second joints, and the connecting structure includes mounting rings provided on the outer sides of the ends of the first and second joints close to each other, a sealing ring is provided between the mounting rings, and a plurality of assembly holes are provided on the mounting rings along the circumference, and the corresponding assembly holes are installed by bolts; a limiting groove is provided in the first joint, and the inner side surface of the limiting groove is serrated; a limiting ring is provided on the outer side of the second joint, and the outer side of the limiting ring is serrated, and the limiting ring can be inserted into the limiting groove;

[0008] A plurality of arc-shaped inserting plates are provided on the outer side of the limiting ring along the circumferential direction, and an arc-shaped slot capable of accommodating the arc-shaped inserting plates is provided inside the joint and outside the limiting groove.

[0009] Furthermore, rubber protective sleeves are provided on the outer sides of the first and second connectors.

[0010] Furthermore, a plurality of cells are provided in the limiting groove and in communication with line one, and a cell slot capable of accommodating the cells is provided in the limiting ring, and the cell slots are all extended into line two.

[0011] Furthermore, a plurality of anti-slip grooves are provided on the outer sides of the joint 1 and the joint 2.

[0012] Furthermore, the shapes, positions and quantities of the arc-shaped inserting plates and arc-shaped slots correspond to each other.

[0013] Furthermore, a through groove capable of communicating with the limiting ring and the second line is provided in the second connector.

[0014] The advantages of this utility model compared with the prior art are:

[0015] The adjacent joints are used for secure installation, without the need for separate clamping components. This makes the structure compact and easy to install and use.

[0016] The mutual cooperation of the serrations can greatly improve the torsional resistance of the connection, and the radial tensile resistance can be achieved through the installation ring, so that it is firm and stable after installation and is not easy to be disengaged or rotated by external forces.

[0024] Combined with attachment Figure 2-4 A connecting structure is provided between the joint 1 3 and the joint 2 4. The connecting structure includes mounting rings 6 provided on the outer sides of the ends of the joint 1 3 and the joint 2 4 that are close to each other. A sealing ring 7 is provided between the mounting rings 6. Several assembly holes are provided on the mounting rings 6 along the circumferential direction, and the corresponding assembly holes are installed by bolts; the sealing ring 7 can avoid the two mounting rings 6 from hard extrusion contact, forming a buffer, and is not easily damaged after long-term use.

[0025] Combined with attachment Figure 2-4 A limiting groove 8 is provided in the connector 1 3, and the inner side surface of the limiting groove 8 is serrated. A limiting ring 9 is provided on the outer side of the connector 2 4, and the outer side of the limiting ring 9 is serrated. The limiting ring 9 can be inserted into the limiting groove 8, so that the serrations on the outer side of the limiting ring 9 and the serrations on the inner side of the limiting groove 8 restrict each other and cannot deflect when subjected to force, so as not to affect the firmness of the installation; a through groove that can be connected with the limiting ring 9 and the line 2 2 is provided in the connector 2 4, so that the internal circuit can pass through.
