Description

Technical Field

[0001] The utility model relates to the technical field of wiring terminals, in particular to an anti-loosening wiring terminal. Background Art

[0002] The terminal block is a piece of metal sealed in insulating plastic. There are holes at both ends of the metal block to insert the wires. It can be tightened or loosened by screws. The terminal block can be used to connect two wires and can be disconnected at any time without welding or wrapping them together. It is suitable for interconnecting a large number of wires. When connecting the wires to the terminal block, it is usually necessary to bend the wires to prevent them from loosening.

[0003] For example, a utility model with authorization announcement number CN219874082U discloses an anti-loosening terminal, which places the wire between a gasket and a pressing plate, so that the wire contacts the round shaft, and the screw is turned to drive the pressing plate to rotate and move downward. The rotation of the pressing plate drives the dial shaft to rotate, thereby moving the wire to bend the wire, and the pressing plate moves downward to press the wire tightly, thereby preventing the wire from loosening.

[0004] This prior art also has the following problems when used:

[0005] When the device extends the wire between the gasket and the pressing plate, the dial shaft may block the movement of the wire, and it is necessary to visually inspect the position of the dial shaft and turn the screw to adjust the position of the dial shaft, resulting in inconvenience in operation. After the device bends the wire, the wire is likely to rebound or even return to its original state when the dial shaft continues to rotate, thereby reducing the degree of bending of the wire when the pressing plate presses the wire, increasing the risk of the wire loosening and falling off.

[0025] Please refer to Figure 1-Figure 4 As shown, the utility model provides an anti-loosening terminal, including a terminal base 1, a bolt 4 and a pressing piece 5. The terminal base 1 is provided with a plurality of grooves, in which gaskets 2 are fixedly arranged, a U-shaped frame 3 is fixedly arranged on the top surface of the gasket 2, a bolt 4 is arranged above the gasket 2, a pressing piece 5 is arranged at the bottom of the bolt 4, the bolt 4 penetrates the U-shaped frame 3 and is threadedly connected with the U-shaped frame 3, a turntable 14 is fixedly arranged on the bottom surface of the bolt 4, the turntable 14 is arranged inside the pressing piece 5, the outer side and the upper and lower sides of the turntable 14 are rotatably connected with the pressing piece 5, rotating the bolt 4 can drive the bolt 4 to move upward or downward, and the turntable 14 can conveniently drive the pressing piece 5 to move up and down when the bolt 4 moves up and down.

[0026] like Figure 1-Figure 4As shown, the bottom surface of the pressing sheet 5 is provided with a bending assembly, which is composed of a bending block 6, a push block 7, a connecting rod 8, a lifting plate 9, a T-shaped slider 11 and a T-shaped slide groove 12. The top surface of the gasket 2 is respectively provided with a bending block 6 and a push block 7. The bottom surface of the pressing sheet 5 is hinged with a connecting rod 8, and the other end of the connecting rod 8 is hinged to the side of the push block 7. The bottom surface of the push block 7 is slidably connected with the lifting plate 9. The bottom surface of the push block 7 is fixedly provided with a T-shaped slider 11. The top surface of the lifting plate 9 is provided with a T-shaped slide groove 12 adapted to the T-shaped slider 11. The T-shaped slider 11 is connected to the bottom surface of the push block 7 by the T-shaped slider 11. The slide groove 12 is slidably connected with the lifting plate 9, and the bending assembly can avoid driving the pressing plate 5 to rotate when the bolt 4 is turned. The wire is inserted into the bending block 6 on the top surface of the gasket 2, close to the side of the push block 7 until it contacts the wiring base 1. The bolt 4 is turned to drive the bolt 4 and the pressing plate 5 to move downward. The pressing plate 5 moves downward to drive the connecting rod 8 to rotate. The connecting rod 8 rotates to drive the push block 7 to move horizontally. The push block 7 contacts the wire to push the wire, thereby bending the wire. The operation is convenient and quick. When the pressing plate 5 continues to move downward, the bent wire is difficult to rebound.

[0027] like Figure 1-Figure 3 As shown, a lifting component is arranged below the bending component, and the lifting component consists of a first lifting chamber 10, a first return spring 13, a second lifting chamber 15, and a second return spring 16. The top surface of the gasket 2 is respectively provided with the first lifting chamber 10 and the second lifting chamber 15, the first lifting chamber 10 is adapted to the lifting plate 9, and the lifting plate 9 is slidably connected with the gasket 2 through the first lifting chamber 10, the second lifting chamber 15 is adapted to the bending block 6, and the bending block 6 is slidably connected with the gasket 2 through the second lifting chamber 15, the bottom surface of the lifting plate 9 is fixedly provided with a first return spring 13, and one end of the first return spring 13 away from the lifting plate 9 is fixedly connected to the inner bottom surface of the first lifting chamber 10, the bottom surface of the bending block 6 is fixedly provided with a second return spring 16, and the second return spring 16 is fixedly provided with a second return spring 16. The end of the positioning spring 16 away from the bending block 6 is fixedly connected to the bottom surface of the second lifting chamber 15. When the pressing sheet 5 does not contact the bending block 6 and the pushing block 7, the top surfaces of the bending block 6 and the pushing block 7 are located in the same horizontal plane. The downward thrust of the connecting rod 8 on the pushing block 7 in the vertical direction is much smaller than the force required for the lifting plate 9 to move downward. If the outer diameter of the wire is smaller than the distance between the top surface of the bending block 6 and the pushing block 7 and the top surface of the gasket 2, when the pressing sheet 5 moves downward and contacts the bending block 6 and the pushing block 7, the pressing sheet 5 continues to move downward to drive the bending block 6 and the pushing block 7 to move downward at the same time, and the first return spring 13 and the second return spring 16 are compressed until the pressing sheet 5 presses the wire, thereby avoiding the bending assembly from blocking the pressing sheet 5 from pressing the wire when the outer diameter of the wire is large.

[0028] Specific working principle:

[0029] When the device is in use, the wire is extended into the bending block 6 on the top surface of the gasket 2, close to the pushing block 7, until it contacts the wiring base 1, the bolt 4 is rotated to drive the bolt 4 and the pressing plate 5 to move downward, the pressing plate 5 moves downward to drive the connecting rod 8 to rotate, and the connecting rod 8 rotates to drive the pushing block 7 to move horizontally, and the pushing block 7 contacts the wire to push the wire, thereby bending the wire. The operation is convenient and quick, and the bent wire is difficult to rebound when the pressing plate 5 continues to move downward until the pressing plate 5 contacts the wire and presses the wire to prevent the wire from loosening. If the outer diameter of the wire is smaller than the distance between the top surface of the bending block 6 and the pushing block 7 and the top surface of the gasket 2, when the pressing plate 5 moves downward and contacts the bending block 6 and the pushing block 7, the pressing plate 5 continues to move downward to drive the bending block 6 and the pushing block 7 to move downward at the same time, and the first return spring 13 and the second return spring 16 are compressed until the pressing plate 5 presses the wire, thereby avoiding the bending component from blocking the pressing plate 5 from pressing the wire when the outer diameter of the wire is large.
