Description

Technical Field

[0002] Binding posts, commonly known as terminal blocks, are components used to connect wires and are widely used in various electronic devices. Their main function is to serve as connection points between electronic components to facilitate circuit construction and maintenance. The design of binding posts needs to consider factors such as current capacity, voltage level, and contact resistance to ensure the reliability and safety of electrical connections. During the use of binding posts, in order to prevent loose connections due to vibration and other reasons, the binding posts need to be fixed and insulated.

Then, press the driving plate 1003 downward to push the movable column 1002 to move downward along the inner wall of the fixed cover 5. At this time, the insertion strip 1001 is movably connected to the interior of the slot 1 12, thereby pushing the movable rod 902 to move downward synchronously, so that the wire pressing column 901 moves downward. At this time, the reset spring 903 stretches and lengthens, thereby pressing the surface of the cable 2 until the wire pressing column 901 stops moving.

[0025] The inserting strip 1001 is movably connected to the inside of the slot 12, thereby pushing the movable rod 902 to move downward synchronously, causing the wire pressing post 901 to move downward. At this time, the return spring 903 is stretched and lengthened, thereby pressing the surface of the cable 2 until the wire pressing post 901 stops moving. The inserting strip 1001 is inserted into the inside of the slot 2 13, driving the mounting post 6 to rotate synchronously inside the fixed cover 5, thereby winding the cable 2 around the outside of the mounting post 6, conveniently increasing the contact area between the cable 2 and the mounting post 6, thereby reducing the contact resistance and reducing the resistance to current flow.

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, the extrusion rotation mechanism 10 includes an insertion strip 1001, a moving column 1002 and a driving plate 1003. The top of the insertion strip 1001 is fixedly connected to the bottom of the moving column 1002, and the moving column 1002 is movably connected to the inner side of the fixed cover 5. The top of the moving column 1002 is provided with a movable groove 11, and the driving plate 1003 is movably connected to the inside of the movable groove 11, and the surface of the driving plate 1003 is provided with an operating hole 15. The top of the movable rod 902 is provided with a slot 12, and the insertion strip 1001 is adapted to the slot 12.

[0027] The driving plate 1003 is pressed downward to push the movable column 1002 to move downward along the inner wall of the fixed cover 5. At this time, the inserting strip 1001 is movably connected to the inside of the slot 12, thereby pushing the movable rod 902 to move downward synchronously, so that the wire pressing column 901 moves downward, and the inserting strip 1001 is inserted into the inside of the slot 2 13. Subsequently, the driving plate 1003 is rotated. Since the driving plate 1003 is movably connected to the inside of the movable groove 11, the movable column 1002 is driven to rotate inside the fixed cover 5 until the limiting rod 1007 is aligned with the limiting hole 14. Under the action of the compression spring 1006, the limiting rod 1007 is pushed to be inserted into the inside of the limiting hole 14. At this time, the movable column 1002 remains fixed. On the contrary, the driving plate 1003 is lifted upward to drive the limit bar 1004 to move inside the movable column 1002. Under the action of the control rope 1005, the insertion rod is separated from the insertion hole. Then the driving plate 1003 is rotated in the opposite direction.

[0028] Working principle: When in use, first, insert the end of the cable 2 into the interior of the mounting cover 1, and pass the end of the cable 2 through the wire fixing hole 7 of the mounting column 6, then, press the driving plate 1003 downward to push the movable column 1002 to move downward along the inner wall of the fixed cover 5, at this time, the inserting strip 1001 is movably connected to the interior of the slot one 12, thereby pushing the movable rod 902 to move downward synchronously, so that the wire pressing column 901 moves downward, at this time, the reset spring 903 stretches and lengthens, thereby pressing the surface of the cable 2 until the wire pressing column 901 stops moving, at this time, the inserting strip 1001 is inserted into the interior of the slot two 13, then, rotate the driving plate 1003, because the driving plate 1003 is movably connected to the interior of the movable groove 11, thereby driving the movable column 1002 to rotate inside the fixed cover 5, because the inserting strip 1001 is inserted into the interior of the slot two 13, thereby driving the mounting column 6 rotates synchronously inside the fixed cover 5, so as to wrap the cable 2 around the outer side of the installation column 6, until it rotates to align the limit rod 1007 with the limit hole 14, and under the action of the compression spring 1006, the limit rod 1007 is pushed to insert into the limit hole 14. At this time, the movable column 1002 remains fixed. On the contrary, the driving plate 1003 is lifted up to drive the limit bar 1004 to move inside the movable column 1002. Under the action of the control rope 1005, the insertion rod is separated from the insertion hole, and then the rod driving plate 1003 is rotated in the opposite direction.
