Description

Technical Field

[0001] The utility model relates to the field of electric wires and cables, in particular to a flame retardant wiring block. Background Art

[0002] Terminal blocks are auxiliary equipment for electrical connections, used to fix and distribute wires. They are usually made of insulating materials and have multiple wiring points to facilitate the connection and management of circuits. They are widely used in industrial automation, power systems and electronic equipment to improve the efficiency and safety of electrical installations. The design of terminal blocks takes into account the current carrying capacity, corrosion resistance and the need for easy installation and maintenance. They are an indispensable part of modern electrical engineering. In the application of existing technologies, terminal blocks are usually directly exposed to the air. Although this layout is convenient for installation and maintenance, it inevitably makes its surface an accumulation place for dust and pollutants. Dust particles suspended in the air are continuously deposited on the surface of the terminal block over time, which not only affects the neatness of its appearance, but more seriously may have an adverse effect on the electrical performance of the terminal block. For this reason, we propose a flame-retardant terminal block. Utility Model Content

[0026] A locking assembly, which is mounted on the two sets of side panels 3 and is used to retract the dust cover 4;

[0027] The placement component is installed on the top of the flame-retardant terminal block 1 to keep the dust cover 4 parallel when it is lowered.

[0028] The two ends of the two groups of dust covers 4 are respectively fixedly connected with the second rotating rod 6 near the top position, and the two ends of the two groups of dust covers 4 are respectively fixedly connected with the first rotating rod 5 near the bottom position. Then the two groups of dust covers 4 are rotated in opposite directions, and the dust covers 4 are rotated ninety degrees between the two groups of side panels 3 using the two groups of first rotating rods 5.

[0029] The ends of the two groups of first rotating rods 5 that are away from each other are respectively rotatably connected to the inner walls of the two groups of side panels 3. The two groups of dust covers 4 use the first rotating rods 5 to rotate ninety degrees between the two groups of side panels 3, so that the top of the flame retardant terminal block 1 can be well covered, effectively preventing the problem of failure of the flame retardant terminal block 1 due to excessive dust on the top of the flame retardant terminal block 1, ensuring the cleanliness of the flame retardant terminal block 1 and improving the service life of the flame retardant terminal block 1.

[0030] The placement component includes a hinge seat 11 and a notch 12. The top of the flame-retardant terminal block 1 is fixedly provided with hinge seats 11 corresponding to the four corners. The top of the hinge seat 11 is provided with a notch 12 near one side. The outer walls of the two groups of second rotating rods 6 are fitted with the notch 12, and the two groups on the dust cover 4 are just rotated into the notch 12 on the hinge seat 11 to block dust on the top of the flame-retardant terminal block 1.

[0031] Both sides of the two groups of side panels 3 are provided with empty grooves 7, and the second rotating rod 6 is movably installed in the empty grooves 7. By utilizing the two groups of card blocks 10, the two groups of card blocks 10 drive the card plates 9 to slide in the two groups of slide grooves 8, and the card plates 9 block the second rotating rod 6, so that the flame-retardant terminal block 1 can open the two groups of dust covers 4 during maintenance, thereby improving the speed of maintenance.

After the dust covers 4 are rotated ninety degrees between the two groups of side panels 3 using the two groups of first rotating rods 5, the two groups of dust covers 4 are just rotated to the notches 12 on the hinge seat 11 to block dust on the top of the flame retardant terminal block 1. The dustproof plates 13 on the two groups of dust covers 4 prevent dust from falling on the edge of the top of the flame retardant terminal block 1. When the dust covers 4 need to be stored, the above operation can be performed in reverse.
