[0002] Broadcast television signal transmission cables are the core physical medium for carrying audio and video signals. Their performance directly affects signal quality and transmission stability. Televisions receive radio signals by connecting antennas through signal transmission cables. The connectors of the signal transmission cables are directly connected to the television signal receiving port. Their robustness is particularly important for the stability of television signal reception. If the cable connectors are damaged, the cable connectors need to be replaced.

[0003] In traditional broadcast television signal cable installation, tools are needed to securely fasten the metal wires at the cable end to the connector to ensure a firm installation. This process is inconvenient, results in low connection efficiency, and requires professional personnel to operate the tools. Utility Model Content

[0004] This utility model provides a quick-assembly and disassembly connection structure for broadcast television signal transmission cables, which solves the problem that in traditional broadcast television signal cables, when installing cable end connectors, tools are needed to fix and lock the metal wires at the cable end into the cable end connector in order to ensure the installation of the cable connector firmly. This operation is not convenient, the connection efficiency of the cable connector is low, and it requires professional personnel to operate with hand tools.

[0005] This utility model provides a quick-assembly and disassembly connection structure for broadcast television signal transmission cables, specifically including: a connector body, a wire end through hole longitudinally through the center of the connector body, a cable socket at the center of the bottom of the connector body, the wire end through hole being coaxial with the cable socket, an aluminum alloy spiral sleeve fixedly connected to the lower end of the connector body, two sleeve adjustment notches on the side wall of the spiral sleeve, an elastic locking plate fixedly connected inside the sleeve adjustment notches, and a tightening sleeve installed outside the spiral sleeve.

[0006] Furthermore, the outer surface of the spiral sleeve is provided with an external thread, and the lower edge of the inner wall of the spiral sleeve is provided with an adjustment notch.

[0007] Furthermore, the outer surface of the elastic locking plate is provided with a locking plate outer wedge surface with a beveled structure, and the lower end of the elastic locking plate is fixedly connected with a lower locking ring with an arc-shaped structure.

[0008] Furthermore, the lower locking ring is coaxial with the spiral sleeve, and the lower locking ring is located inside the inner edge groove.

[0009] Furthermore, the inner surface of the lower locking ring is provided with locking ring anti-slip texture, the cross-section of the locking ring anti-slip texture is triangular, and the conical end of the locking ring anti-slip texture faces obliquely upward.

[0010] Furthermore, the inner wall of the tightening sleeve is provided with an internal thread, which is helically connected to the external thread of the connecting sleeve.

[0011] Furthermore, the outer surface of the tightening sleeve is provided with a sleeve anti-slip strip, and the lower edge of the inner wall of the tightening sleeve is machined with a sleeve inner edge chamfer.

[0012] This utility model provides a broadcast television signal transmission cable connection structure that can be quickly assembled and disassembled, and has the following beneficial effects:

[0013] In this utility model, the connector of the television signal transmission cable has been improved. When the cable connector is connected to the cable, no special tools are required. Simply rotate the tightening sleeve located outside the spiral sleeve to retract the elastic locking plate and lock the cable through the tight contact between the locking ring anti-slip texture and the cable. For cable maintenance, the cable connector of this utility model is easier to install at the end of the cable, the operation is quick, the installation difficulty is low, and no professional personnel are required to operate and install it.

[0014] Furthermore, the spiral sleeve and tightening sleeve in this application are connected by a spiral connection between the external thread of the sleeve and the internal thread of the sleeve.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Example 1: Please refer to Figures 1 to 7 :

[0029] This utility model proposes a quick-assembly and disassembly connection structure for broadcast television signal transmission cables, comprising: a connector body 1, a wire end through hole 101 extending longitudinally through the center of the connector body 1, a cable socket 102 at the bottom center of the connector body 1, the wire end through hole 101 being coaxial with the cable socket 102, an aluminum alloy spiral sleeve 4 fixedly connected to the lower end of the connector body 1, two sleeve adjustment notches 401 on the side wall of the spiral sleeve 4, an elastic locking plate 5 fixedly connected inside the sleeve adjustment notches 401, a tightening sleeve 6 installed outside the spiral sleeve 4, an external thread 403 on the outer surface of the spiral sleeve 4, a sleeve adjustment notch 401 on the lower edge of the inner wall of the spiral sleeve 4, and the outer surface of the elastic locking plate 5... The locking plate 5 has an outer wedge surface 501 with a beveled structure. The lower end of the elastic locking plate 5 is fixedly connected to a lower locking ring 502 with an arc-shaped structure. When the tightening sleeve 6 is rotated, the tightening sleeve 6 moves away from the connector socket 103 and fits tightly against the outer wedge surface 501 of the locking plate when the inner thread 601 of the sleeve is threadedly connected to the outer thread 403 of the connector. As the tightening sleeve 6 continues to rotate and move, it continuously presses the outer wedge surface 501 of the locking plate inward, causing the elastic locking plate 5 to deform and bend towards the center of the spiral connector 4, so that the lower locking ring 502 approaches and contacts the outer surface of the cable. As the elastic locking plate 5 bends further, the anti-slip texture 503 of the locking ring fits tightly against the outer surface of the cable, and the cable is locked by the anti-slip texture 503 of the locking ring.

[0030] In this embodiment, the lower locking ring 502 is coaxial with the spiral sleeve 4, and the lower locking ring 502 is located inside the inner edge groove 402. Under normal conditions, the lower locking ring 502 is stored in the inner edge groove 402, so that the cable can be easily inserted into the spiral sleeve 4 and the cable socket 102.

[0031] In this embodiment, the inner surface of the lower locking ring 502 is provided with a locking ring anti-slip texture 503. The cross-section of the locking ring anti-slip texture 503 is triangular, and the conical end of the locking ring anti-slip texture 503 faces obliquely upward. Through the locking ring anti-slip texture 503 of the secondary structure, the elastic locking plate 5 deforms and bends towards the center of the spiral sleeve 4, so that the lower locking ring 502 approaches and contacts the outer surface of the cable. As the elastic locking plate 5 bends further, the locking ring anti-slip texture 503 fits tightly with the outer surface of the cable, and the cable is locked by the locking ring anti-slip texture 503. The locking ring anti-slip texture 503 with the conical end facing upward can lock the cable more effectively and prevent the cable from slipping out of the spiral sleeve 4.

[0032] In Example 2, based on Example 1, the inner wall of the tightening sleeve 6 is provided with an internal thread 601, which is helically connected to the external thread 403 of the connecting sleeve. The outer surface of the tightening sleeve 6 is provided with a sleeve anti-slip strip 602, and the lower edge of the inner wall of the tightening sleeve 6 is machined with a sleeve inner edge chamfer 603. The spiral connecting sleeve 4 and the tightening sleeve 6 are connected by the spiral connection between the external thread 403 of the connecting sleeve and the internal thread 601 of the sleeve. The spiral connecting sleeve 4 locks the elastic locking plate 5, limits the elastic locking plate 5, and keeps the anti-slip texture 503 of the locking ring tightly clamped to the cable. Compared with the traditional locking method that uses the deformation of the metal locking ring, the threaded connection method is more secure and will not deform or loosen due to external force.

[0033] The working principle of this embodiment is as follows: When connecting the cable and the connector, the cable end is cut with a tool to expose the internal metal wire end. The cable is then inserted into the spiral sleeve 4 into the cable socket 102. The metal wire end passes through the wire end through hole 101 into the connector socket 103. The spiral sleeve 6 is rotated and tightened. When the spiral sleeve 6 is threadedly connected to the external thread 403 of the sleeve through the internal thread 601, the tightening spiral sleeve 6 moves away from the connector socket 103 and fits tightly against the outer wedge surface 501 of the locking plate. As the tightening spiral sleeve 6 continues to rotate and move, it compresses the outer wedge surface 501 of the locking plate, causing the elastic locking plate 5 to deform and bend towards the center of the spiral sleeve 4. This causes the lower locking ring 502 to approach and contact the outer surface of the cable. As the elastic locking plate 5 bends further, the anti-slip texture 503 of the locking ring fits tightly against the outer surface of the cable. Under the action of friction, the connector and the cable are fixedly connected.
