Description

Technical Field

[0001] This utility model relates to the field of quick-connect cable technology, and in particular to a quick-connect device for signal cables used in broadcasting and television engineering. Background Technology

[0002] In broadcast television engineering, reliable connection of coaxial signal cables is crucial. Traditional connection methods often employ spiral inlet plugs or simple plug-in structures. These existing technologies have significant shortcomings in practical applications: First, spiral connections are cumbersome to operate, inefficient in special environments such as underground and overhead where faulty equipment needs replacing or lines need adjustment, increasing operation time and technical barriers; second, traditional connection structures are prone to loosening under vibration, leading to unstable or even interrupted signal transmission; third, most connection devices lack effective anti-misinsertion and anti-rotation designs, easily resulting in poor contact or damage due to improper operation. Although some fields have adopted F or BNC plug-type connection devices, their structural design is not well-matched to the special requirements of broadcast television engineering signal cables, especially failing to provide targeted solutions for frequent plugging and unplugging and vibration resistance. Furthermore, existing connection devices often fail to adequately consider the balance between quick plugging and unplugging and reliable locking, either sacrificing stability for connection speed or complicating operation to ensure stability.

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.

[0026] Please refer to Figures 1 to 4 :

[0027] Example 1: This utility model proposes a quick connection device for signal cables used in broadcasting and television engineering, including: terminal A 1 and terminal B 2; terminal A 1 and terminal B 2 are connected to each other; terminal A 1 has a metal female terminal 101 embedded in it, and terminal B 2 has a metal male terminal 4 slidably embedded in it; when terminal A 1 and terminal B 2 are connected to each other, the female terminal 101 and the male terminal 4 are connected to each other, so that terminal A 1 and terminal B 2 are locked together.

[0028] The outer end of the female terminal 101 is provided with an internal thread 102, which is connected to the external cable terminal.

[0029] The inner end of the female terminal 101 is a T-shaped mating plug 103. The mating plug 103 has a flat structure. A U-shaped slot 1031 is provided in the middle of the end of the mating plug 103. A mating core groove 1032 is recessed in the middle of the slot 1031. The mating core groove 1032 is electrically connected to the internal thread 102 of the female terminal 101.

[0030] Among them, horizontal movable slots 201 are respectively opened in the left and right side walls of the wiring B end 2, the outer end of the wiring B end 2 is an external screw connector 202, and the inner cavity of the wiring B end 2 is provided with a rotating cavity 203 with an enlarged diameter at the end near the wiring A end 1. The mating plug 103 can rotate in the rotating cavity 203. The part of the rotating cavity 203 perpendicular to the wiring B end 2 is provided with a platform groove for stopping the mating plug 103 from moving outward.

[0031] In Example 2, based on Example 1, an external wiring 401 is provided at the outer end of the connector 4. The external wiring 401 passes outward through the external threaded connector 202. A spring 402 is provided in the cavity of the connector B end 2 between the connector 4 and the external threaded connector 202. An anti-rotation insert plate 403 is fixedly provided at the inner end of the connector 4. The left and right ends of the anti-rotation insert plate 403 slide through the corresponding movable strip holes 201 respectively. The end of the anti-rotation insert plate 403 is inserted into the slot 1031 of the docking block 103. At this time, the docking block 103 cannot move outward and is stopped by the platform groove of the rotating cavity 203. Anti-slip side strips 4031 are provided on the side walls of the left and right ends of the anti-rotation insert plate 403. A docking core post 4032 is embedded in the middle of the anti-rotation insert plate 403. One end of the docking core post 4032 is electrically connected to the external wiring 401, and the other end is connected and inserted into the docking core groove 1032.

[0032] A ring-shaped alignment ring 3 is fixedly provided on the ring wall of the opposite end of the wiring A terminal 1 and the wiring B terminal 2. A triangular mark is provided on the alignment ring 3. The triangular mark on the alignment ring 3 of the wiring A terminal 1 corresponds to the flat surface of the mating plug 103, and the triangular mark on the alignment ring 3 of the wiring B terminal 2 corresponds to the flat surface of the anti-rotation plug plate 403.

[0033] The following provides further explanation and description of the functions and effects of each structure mentioned above, to help those skilled in the art better understand the technical solution:

[0034] The embedded metal female terminal 101 at terminal A and the slidingly integrated metal male terminal 4 at terminal B constitute the main electrical connection components. The choice of metal material ensures good conductivity and durability, while the sliding integrated design provides the necessary fault tolerance and a smooth plugging and unplugging experience during the connection process.

[0035] The internal thread 102 on the outer end of the female connector 101 is used for a secure connection with the external cable connector. The threaded connection provides reliable mechanical fastening and electrical contact, effectively resisting loosening caused by vibration and ensuring the stability of signal transmission. The T-shaped flat mating plug 103 at its inner end, the U-shaped slot 1031 at its outer end, and the mating groove 1032 in the middle constitute a precision mating interface. The T-shaped structure prevents mis-insertion, the U-shaped slot 1031 accommodates the anti-rotation plug 403, and the mating groove 1032 ensures precise alignment and electrical connection of the mating core 4032. This design guarantees the accuracy of signal transmission.

[0036] On terminal B 2, the horizontal movable slots 201 on the left and right sidewalls provide sliding tracks for the anti-rotation insert 403, restricting its movement path and ensuring that the insert can only move horizontally to accurately connect with the slot 1031. The external threaded connector 202 at the outer end of terminal B 2 is used to connect external cables. The internal rotating cavity 203 allows the mating insert 103 to rotate within a certain range, and its end slot cooperates with the anti-rotation insert 403 to prevent the mating insert 103 from accidentally coming out after connection, enhancing the mechanical reliability of the connection.

[0037] The connector terminal 4 connects to an external cable via its external connector 401. A spring 402 within the cavity between the connector terminal 4 and the external threaded connector 202 provides continuous contact pressure for the entire connection. This pressure ensures a tight electrical contact between the connector terminal 4 and the female connector 101 even under vibration, while also buffering the impact during insertion and removal, reducing wear. This function is similar to the considerations in some connectors to prevent cable damage from frequent insertion and removal. The anti-rotation plate 403 fixed inside the connector terminal 4 is a key locking and anti-rotation component. After being inserted into the slot 1031 of the mating block 103, it effectively prevents relative rotation between the two, thus maintaining a stable connection. Anti-slip side strips 4031 on the left and right side walls of the anti-rotation plate 403 increase the frictional resistance between it and the movable strip hole 201, further enhancing the reliability of the locking mechanism. The mating core post 4032, embedded in the middle of the anti-rotation insert plate 403, is a key signal conduction component. It is electrically connected to the external wiring 401 and is electrically connected to the wiring female terminal 101 by inserting into the mating core groove 1032, thus completing the signal transmission path.

[0038] In summary, this quick-connect device for signal cables used in broadcasting and television engineering achieves multiple benefits, including quick plugging and unplugging, reliable locking, anti-rotation, stable electrical connection, and vibration resistance, through the ingenious collaborative design of components such as the female connector 101, mating plug 103, slot 1031, mating core groove 1032, female connector 4, anti-rotation plate 403, mating core post 4032, and spring 402. This integrated design significantly improves the efficiency and reliability of on-site line connection, adjustment, and maintenance in broadcasting and television engineering, while lowering the operational threshold and technical requirements.
