[0006] 2. This kind of bipolar switch is often used in high-current equipment, and an arc will be generated when it is closed. However, this switch is not equipped with a special arc-extinguishing device. Although the applicable current is small, the arc generated is not dangerous. After a long time of use, an oxide layer will form at the contacts, affecting the quality of the electrical contact
At present, this kind of bipolar switch does not have the function of not allowing open circuit under heavy load
[0007] 3. If there is a short circuit in the high-power electrical appliances used, the air switch with short-circuit protection function on the live wire alone cannot reliably protect the equipment, and the switch does not have short-circuit protection function

[0063] Implementation mode: when using the switch designed by the present invention to install the live wire at the access end, first press inward the disassembly and assembly adjustment lever 4 corresponding to the insertion end of the live wire, and the disassembly and assembly adjustment lever 4 squeezes the corresponding third electric piece through the pressing plate 26 11, so that the third electric piece 11 is compressed and deformed, and the area for the insertion of the live wire is released; after that, the external live wire is inserted into the live wire insertion port 5; After contact, the first limiting block 14 will be squeezed by the second inclined surface 33 on the first limiting block 14, so that the first limiting block 14 will move inwardly, that is, the moving part from the live wire insertion port to the inner wall of the port will enter the shell. In the internal wall; after the area of the inserted live wire that has not peeled off the insulation is i...

The invention belongs to the technical field of switches, and particularly relates to a quick-release safety switch which comprises a switch outer shell, a switch inner shell, a switch button, a disassembly and assembly adjusting rod, a first electric piece, a second electric piece, a third electric piece, a fourth electric piece and a fifth electric piece. When a live wire is installed, the inserted live wire is limited through a first limiting block installed in the switch inner shell; and meanwhile, compared with the use of an auxiliary tool, the external sliding prevention method is more convenient to use, so that the electric shock hidden danger caused by the fact that the installed live wire slides out is prevented. When a live wire on a live wire insertion opening is disassembled, a disassembly and assembly adjusting rod corresponding to the live wire insertion end is pressed inwards, after a third electric piece loses pressing force on the live wire, the disassembly and assembly adjusting rod continues to be pressed, and two first limiting blocks move inwards through transmission of the disassembly and assembly adjusting rod, a pressing plate, a pressing block, a pushing block, a triggering pushing plate and a pushing inclined plate; and the limiting effect on the live wire is relieved, so that the live wire can be smoothly pulled out, and the use is relatively convenient.
Description
technical field [0001] The invention belongs to the technical field of switches, in particular to a quick-release safety switch. Background technique [0002] In the existing switch, the connection and connection of electric wires are usually fixed by means of bolt fastening, and the bolts need to be manually twisted turn by turn, which is inconvenient to operate. [0003] A bipolar switch refers to a switch with two neutral wires in and two live wires in, two neutral wires out and two live wires out; for this kind of switch, in order to facilitate installation and disassembly, it is often set on the switch Quick-release parts; this part clamps the wires through elastic conductive sheets, does not require a screw structure, and is more convenient to operate. For example, patent 2018212475486 discloses a quick-connect wiring device, which can realize the function of quick wiring. [0004] However, this bipolar switch with a quick-connect wiring device also has the following ...
