DETAILED DESCRIPTION

[0016] Reference Figures 1 to 2 The embodiments of the present invention are further described.

[0017] A firmly fixed terminal comprises a base 1, a fixing mechanism 4, a limiting member 5 and a positioning member 6. The base 1 is provided with a fixing groove 2 and a feed groove 3 which are interconnected. The positioning member 6 is placed in the fixing groove 2. The fixing mechanism 4 is placed on the base 1. The fixing mechanism 4 cooperates with the positioning member 6. The limiting member 5 is placed in the feed groove 3.

[0018] The fixing mechanism 4 includes a knob 41, a screw rod 42, a fixing block 43 and a gasket 44. The knob 41 is placed on the base 1. The knob 41 is provided with anti-slip grooves and is rotatably connected to the base 1. The screw rod 42 is placed in the fixing groove 2 and is connected to the knob 41. The gasket 44 is placed in the fixing groove 2 and contacts the inner wall of the fixing groove 2. The gasket 44 has a threaded hole 7. The screw rod 42 passes through the threaded hole 7 and is threadedly connected to the threaded hole 7. The fixing block 43 is fixed to the gasket 44 and has a storage hole 8 corresponding to the threaded hole 7. The screw rod 42 extends into the storage hole 8.

[0019] By rotating the knob 41, the knob 41 drives the screw rod 42 to rotate. Since the screw rod 42 is threadedly connected to the threaded hole 7, the rotation of the screw rod 42 drives the gasket 44 to move, and the gasket 44 drives the fixing block 43 to move. At the same time, the screw rod 42 extends from the storage hole 8 until the fixing block 43 contacts the wire, thereby fixing the wire in the base 1. At the same time, the wire is fixed by providing a limit member 5, thereby effectively preventing the wire from detaching or loosening during the movement or use of the terminal, thereby greatly improving the stability and reliability of the connection.

[0020] The positioning member 6 includes a first spring 61, a telescopic rod 62 and a support plate 63. The telescopic rod 62 is placed in the fixed groove 2, and the two ends of the telescopic rod 62 are fixedly connected to the inner wall of the fixed groove 2 and the support plate 63 respectively. The first spring 61 is sleeved on the telescopic rod 62, and the two ends of the first spring 61 are respectively in contact with the support plate 63 and the inner wall of the fixed groove 2;

[0021] The fixed block 43 squeezes the wires, and the support plate 63 is forced to move, which drives the first spring 61 to squeeze and simultaneously drives the telescopic rod 62 to extend and retract until the telescopic rod 62 can no longer extend and retract, and then the movement of the fixed block 43 is stopped. Then, the elasticity of the first spring 61 and the squeezing of the wires by the fixed block 43 can better fix the wires in the base 1.

[0022] The limiting member 5 includes a first clamping plate 51, a second clamping plate 52, a second spring 53, a connecting rod 54, an annular piece 55 and a card 56. The first clamping plate 51 is fixed in the feed trough 3. The first clamping plate 51 is provided with a first groove 9. The base 1 is provided with a connecting hole 11 and a storage groove 12 that are interconnected. The storage groove 12 is connected to the feed trough 3. The second clamping plate 52 is placed in the storage groove 12. The connecting rod 54 passes through the connecting hole 11 and is fixed to the second clamping plate 52. The second clamping plate 52 is provided with a second groove 10. The annular piece 55 is fixed at both ends of the connecting hole 11. The card 56 is placed in the connecting hole 11 and fixed to the connecting rod 54. The second spring 53 is sleeved on the connecting rod 54. The card 56 cooperates with the annular piece 55.

[0023] By pulling the connecting rod 54, the connecting rod 54 drives the card 56 to move, and the card 56 squeezes the second spring 53. At the same time, the connecting rod 54 drives the second clamping plate 52 to move into the storage slot 12. When the wire extends into the feed slot 3 and passes through the first groove 9, the connecting rod 54 is loosened, and the squeezing force of the card 56 on the second spring 53 is reduced. The second spring 53 drives the card 56 to move, and the card 56 drives the connecting rod 54 to move, and the connecting rod 54 drives the second clamping plate 52 to move until the second groove 10 on the second clamping plate 52 and the first groove 9 on the first clamping plate 51 respectively contact the wire, thereby fixing the wire in the base 1, thereby effectively preventing the wire from detaching or loosening during the movement or use of the terminal, thereby greatly improving the stability and reliability of the connection.

[0024] Working principle: First, pull the connecting rod 54, and then the connecting rod 54 drives the card 56 to move in the connecting hole 11, and then the card 56 squeezes the second spring 53, and at the same time, the connecting rod 54 drives the second card plate 52 to move from the feed trough 3 to the storage slot 12, and then the wire is inserted into the feed trough 3 and passes through the first groove 9 of the first card plate 51 until it is inserted into the fixed slot 2 and placed on the support plate 63. At this time, the connecting rod 54 is released, and then the squeezing force of the card 56 on the second spring 53 is reduced, and then the second spring 53 drives the card 56 to move in the connecting hole 11, and the card 56 drives the connecting rod 54 to move, and then the connecting rod 54 drives the second card plate 52 to move from the storage slot 12 to the feed trough 3 until the second card The second groove 10 on the plate 52 contacts the surface of the wire, thereby fixing the wire, and then the knob 41 is rotated, and the knob 41 drives the screw rod 42 to rotate, and then the screw rod 42 drives the gasket 44 to move in the storage groove 12, and at the same time the gasket 44 drives the fixing block 43 to move, and at the same time the screw rod 42 extends into the storage hole 8 until the fixing block 43 contacts the wire, and the fixing block 43 squeezes the wire, so that the support plate 63 is forced to move downward, and then the support plate 63 drives the telescopic rod 62 to extend and retract, and the support plate 63 drives the first spring 61 to squeeze, until the telescopic rod 62 is no longer extended, and the elasticity of the first spring 61 drives the support plate 63 to move and squeeze the wire with the fixing block 43, thereby fixing the wire in the base 1.

Any common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
