Description

Technical Field

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

[0002] The terminal block is an accessory product used to achieve electrical connection. The terminal block usually uses screws to tighten or loosen the wires. There is no need for welding, which is convenient for disconnection and easy to use. The existing patent (Announcement No.: CN220439906U) discloses an anti-loosening terminal block. The utility model sets a positioning rod to limit the threaded rod to prevent the wire from being separated from the threaded rod under the action of external force, thereby affecting the connection stability. However, in actual applications, since the threaded rod is fixed to the positioning plate, and the bottom of the positioning plate is fixed with a positioning rod inserted into the wiring frame body, even under the action of the spring, the threaded rod can only be slightly rotated, which makes it difficult to generate effective pressure on the wire, affecting the actual connection effect. To this end, we propose an anti-loosening copper-aluminum terminal block. Utility Model Content

[0003] In order to solve the above problems, the utility model provides an anti-dropping copper-aluminum connecting terminal.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A copper-aluminum terminal block that prevents falling off is designed, comprising a terminal block with a mounting groove inside, sockets at both ends of the terminal block, contacts that are connected to each other at both ends of the mounting groove, a pressure plate above the contact, protective covers fixed at both ends of the top of the terminal block, a screw that is movably connected to the pressure plate is connected between the protective cover and the terminal block, a limiting piece is provided on the screw, the limiting piece comprises a plurality of magnetic cylinders uniformly arranged along the circumference of the top end of the screw, a locking piece is provided on the protective cover, the locking piece comprises a magnetic column with opposite magnetism to the magnetic column, and the magnetic column is movably inserted in the magnetic column.

[0006] In the above solution, the contact piece 1 is V-shaped, and the inner walls at the bottom of both ends of the installation groove are V-shaped and fit with the contact piece 1.

[0007] In the above scheme, a partition is provided on the side of the pressure plate away from the socket, a contact piece 2 is provided between adjacent partitions, a connecting piece is provided between the contact piece 2 and the contact piece 1, slots matching the connecting piece are provided on both sides of the partition, the contact piece 2 is connected to the terminal block by a fastening screw, and a mounting cylinder threadedly connected to the fastening screw is fixed on the terminal block.

[0008] In the above scheme, a limiting cylinder is fixed in the protective cover, and the screw rod 1 is threadedly connected with the limiting cylinder.

[0009] In the above solution, the limiting member includes a limiting cap sleeved on a top end of the screw rod, and the magnetic suction cylinder is fixed to the limiting cap.

[0010] In the above solution, at least two locking members are provided, and the locking members are evenly arranged around the screw rod.

[0011] In the above scheme, the locking member includes a sliding column fixed on the wiring seat, the sliding column is connected to a sliding sleeve, a connecting plate is fixed to one side of the sliding sleeve, and a mounting seat for inserting the magnetic column is connected to the connecting plate through a second screw.

[0012] The advantages and beneficial effects of the utility model are as follows: by setting a limit piece and a locking piece, when the screw rod one rotates to a suitable position, the screw rod one stops rotating and the screw rod two is rotated, so that the mounting seat drives the magnetic suction column to move toward the limit cap, and the magnetic suction column is inserted into one of the magnetic suction cylinders, and the magnetic suction column and the magnetic suction cylinder are adsorbed and fixed by the magnetic force between the magnetic suction column and the magnetic suction cylinder. Compared with the prior art, relatively fixed magnetic suction column and magnetic suction cylinder are used to limit the screw rod one from continuing to rotate, so that the screw rod one is axially fixed, and the screw rod one is prevented from rotating due to external force collision, thereby preventing the screw rod one from moving up and causing the wire to loosen and fall off, thereby enhancing the stability of the wire connection and improving the practicality. By setting a sliding column and a sliding sleeve, the sliding sleeve is moved up and down along the sliding column to adjust the height of the magnetic suction column so as to adapt to the height of the top end of the screw rod one, which is convenient for adjustment.

[0022] Further, a partition 6 integrally formed with the terminal block 1 is provided on the side of the pressure plate 12 away from the socket 11, which divides the interior of the terminal block 1, and each area is used to install wires. A contact piece 2 4 is provided between adjacent partitions 6, and a connecting piece 5 is provided between the contact piece 2 4 and the contact piece 1 3. The contact piece 2 4, the contact piece 1 3 and the connecting piece 5 are integrally formed, so that two wires can be indirectly connected through the contact piece 2 4, the contact piece 1 3 and the connecting piece 5. Slots 7 matching with the connecting piece 5 are provided on both sides of the partition 6, and the connecting piece 5 is installed by using the slots 7.

A screw 14 movably connected to the pressing plate 12 is connected between the protective cover 10 and the terminal block 1. The screw 14 is rotated to move the screw 14 up and down, thereby driving the pressing plate 12 to move up and down. The protective cover 10, on the one hand, protects the screw 14 to prevent direct collision from affecting the stability of the screw 14, and on the other hand, prevents dust from entering the connection between the screw 14 and the terminal block 1, and prevents the tightness of the connection between the two from being affected by dust accumulation;

[0024] Furthermore, a limiting cylinder 13 is fixed in the protective cover 10, and a screw rod 14 is threadedly connected to the limiting cylinder 13; the limiting cylinder 13 is used to limit and position the screw rod 14, restrict the moving track of the screw rod 14, and facilitate the rapid assembly of the screw rod 14;

[0025] The screw rod 14 is provided with a stopper 15, which includes a plurality of magnetic suction cylinders 152 uniformly arranged along the circumference of the top end of the screw rod 14, and the magnetic suction cylinder 152 includes a cylinder body with an inner wall coated with a magnetic coating 1;

[0026] Furthermore, the limiting member 15 includes a limiting cap 151 sleeved on the top of the screw rod 14, and the magnetic tube 152 is fixed to the limiting cap 151. The limiting cap 151 is made of insulating plastic. The limiting cap 151 is sleeved on the screw rod 14 by elastic matching.

The magnetic column 163 includes a column with an outer wall coated with a second magnetic coating, and the second magnetic coating has opposite magnetism to the first magnetic coating;

[0028] Specifically, the magnetic adsorption force is used to make the magnetic column 163 and the magnetic suction cylinder 152 adsorb and fix each other, so as to limit the screw 14, thereby preventing the screw 14 from continuing to rotate and preventing the pressing plate 12 from being driven by the screw 12 to move up and down;

[0029] Furthermore, at least two locking members 16 are provided, and the locking members 16 are evenly arranged around the screw rod 14, and the magnetic columns 163 of the locking members 16 are used to lock with the magnetic cylinders 152 located at different positions;

[0032] Specifically, by setting the limit piece 15 and the locking piece 16, when the screw 14 rotates to the appropriate position, the screw 14 is stopped and the screw 2 164 is rotated, so that the mounting seat 165 drives the magnetic column 163 to move toward the limit cap 151, and the magnetic column 163 is inserted into one of the magnetic cylinders 152, and the magnetic force between the magnetic column 163 and the magnetic cylinder 152 is utilized to make the magnetic column 163 and the magnetic cylinder 152 adsorbed and fixed. Compared with the prior art, the relatively fixed magnetic column 163 and the magnetic cylinder 152 are utilized to limit the screw 14 from continuing to rotate, so that the screw 14 is axially fixed, and the screw 14 is prevented from rotating due to external force collision, thereby preventing the screw 14 from moving up and causing the wire to loosen and fall off, thereby enhancing the stability of the wire connection and improving practicality.
