Problems solved by technology
In many terminal board applications, the terminal board needs to be turned upside down, which brings some troubles to the wiring personnel. If all the screws are withdrawn, they will easily fall off. When operating at high altitude, if the screws fall off, it will cause great trouble.

The invention relates to a terminal block capable of preventing bolts falling off. The terminal block comprises a cover plate, a base, the bolts, hexagon nuts, spring washers, gaskets and copper sheets. A groove is formed in the center of the base and runs through the two ends of the base, a plurality of hexagonal blind holes are formed in the groove, and a circular groove is formed in each hexagonal blind hole, wherein the diameters of the circular grooves are larger than those of the bolts. The hexagonal blind holes are located at the two ends of the groove in a mutually symmetric mode respectively, partition plates are arranged between the hexagonal blind holes at the same end respectively, and fixing holes are formed between the corresponding partition plates and run through the bottom of the base. Clamping grooves are formed in the middles of the inner walls on the two sides of the groove respectively. The terminal block has the advantages that the design is reasonable, the structure is simple, a thread rolling and flanging technology is utilized, the gaskets are clamped to the bolts, and after the bolts get loose completely, the circular holes or hexagonal holes in the cover plate block the gaskets on the bolts so that the bolts cannot fall off when the terminal block is installed in an inverted mode.
Description
technical field [0001] The invention relates to the technical field of electrical engineering devices, in particular to a terminal block for preventing screws from falling off. Background technique [0002] Electrical wiring boards are widely used in various industries as electrical engineering devices. The conventional wiring method is to use screws and gaskets to fix. In many terminal board applications, the terminal board needs to be turned upside down, which brings some troubles to the wiring personnel. If all the screws are withdrawn, they are easy to fall off. When operating at high altitude, if the screws fall off, it will cause great trouble. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a terminal block that prevents the screws from falling off. The design is reasonable and the structure is simple, so that the screws will not fall off when the terminal block is installed upside down. [0004] A terminal b...
