[0003] However, in the prior art, wiring terminals are generally required on the back of the display terminal, and plug-in terminals are used to connect to external input lines. The plug-in terminal input lines are prone to loosening or directly detaching from the clamping mechanism under the action of external pulling force. After disconnection, there is poor contact, which causes input and output failures. In addition, the connection between the terminal and the line body is slow to bend and connect. For this reason, we propose an audio and video display terminal. Utility Model Content

[0027] Working principle:
[0028] When in use, the hydraulic push rod 8 contracts after operation and drives the baffle 7 to move. After the baffle 7 moves, it drives the limit blocks 6 on both sides to slide smoothly in the limit groove 5, so that the positioning column 9 follows the movement driven by the baffle 7. After the positioning column 9 moves, it drives the insulating housing 1 to move toward the end away from the terminal wiring body 4 and separates from it. The external line is inserted from the front end of the insulating housing 1 to the limit frame 23 and then stops. After the external line is inserted, the hydraulic push rod 8 is controlled to operate again from the external controller. After the hydraulic push rod 8 is pushed out, it drives the baffle 7 to move. The stop block 6 moves in the stop groove 5, and the baffle 7 moves the positioning column 9, thereby driving the insulating housing 1 to move. When the insulating housing 1 moves, the driven gear 28 moves, so that the driven gear 28 rolls on the linkage rack 10. When the driven gear 28 rolls, the rotating rod 35 rotates. Under the rotation of the rotating rod 35, the reciprocating screw rod 34 rotates, so that the T-shaped slider 38 moves along the irregular groove of the reciprocating screw rod 34, thereby driving the T-shaped slider 38 to slide downward in the inner groove 37. After the T-shaped slider 38 is lowered, it drives the traction rod 41 to move downward, which is beneficial to the coordination of the internal components and has better linkage. When the insulating housing 1 drives the wire body 15 to enter the terminal wiring body 4, the limit frame 23 enters the bayonet 17 to improve the stability of the terminal. When the T-shaped slider 38 moves, it drives the cross bar 30 to descend. When the cross bar 30 descends, it drives the moving block 22 to slide smoothly in the side groove 27, so that when the cross bar 30 moves, it drives the joint 31 to move downward, and when the joint 31 moves, it drives the lifting rod 26 The bottom plate 24 slides down, and the lifting rod 26 drives the pressing piece 20 to move downward when it descends. After the pressing piece 20 moves, it contacts the wire body 15, and presses the wire body 15 onto the connecting bridge 19 after the pressing piece 20 is pressed down, which is beneficial to the limiting of the connection terminal and the external wire after the connection is completed, and the effect of preventing external force from pulling is better, and the connection quality is improved. The wire body 15 is pressed by the pressing piece 20, and the connecting bridge 19 is in an elastic state under the action of the spring 21, which is beneficial to reduce the wear of the external wire when the line moves, and increase the safety.
