Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0020] Please refer to figure 1 — Figure 5 As shown, the arc baffle clamping packaging structure of the present invention includes an upper arc baffle 1 and a lower arc baffle 2, and the upper arc baffle and the lower arc baffle are respectively provided with inner spacers 4, 6 and outer spacers 3, 5 and the magnetic-conducting part 7, the material of the inner spacer is a gas-producing material, and a groove 18 is provided to cooperate with the static contact, and a groove 15 for fastening with the magnetic-conductive part is reserved, the inner spacer, the outer The spacer embeds the magnetic guide parts in the preset grooves and fastens and clamps each other. When the arc is generated, the arc contacts the gas-generating materials of the left and right inner spacers, making it vaporize and generating gas containing hydrogen. This gas can cool the ...

The invention provides a clamping encapsulation structure for arc barriers. The clamping encapsulation structure comprises an upper arc barrier and a lower arc barrier, wherein the upper arc barrier comprises an inner spacer, an outer spacer and a magnetic conductive iron; the lower arc barrier comprises an inner spacer, an outer spacer and a magnetic conductive iron; one side of each inner spacer is provided with a first groove matched with a fixed contact while the other side is provided with a second groove buckled with the corresponding magnetic conductive iron; one side of each outer spacer is provided with a third groove buckled with the corresponding magnetic conductive iron, the two magnetic conductive irons are respectively embedded in the second groove and the third groove to be matched and connected with the same in a clamping manner by the two sets of inner spacers and outer spacers, the first grooves of the upper arc barrier and the lower arc barrier are opposite to each other and matched and connected with the fixed contact in a clamping manner. According to the clamping encapsulation structure, the magnetic conductive irons are respectively arranged on the upper arc barrier and the lower arc barrier in a clamping manner, the magnetic conductive irons are magnetized simultaneously and endowed with magnetic conduction functions, thus generating driving forces for driving arc and achieving the purpose of improving arc extinguishing capability of an arc extinguishing system.
Description
technical field [0001] The invention relates to the field of low-voltage electrical industry, in particular to an arc shield clamping package structure of a small circuit breaker. Background technique [0002] At present, the manufacturing process of the existing arc chute structure is complicated and costly, and it has no magnetic blowing and air blowing functions, and it cannot play a practical role when it cannot cooperate with the shell and the arc extinguishing chamber, which is not conducive to enhancing the arc extinguishing ability. Contents of the invention [0003] The object of the present invention is to solve the problem of complex manufacturing process and weak arc extinguishing ability of the existing arc shield structure, and provide a small circuit breaker arc shield snap-fit package structure, which simplifies the manufacturing process and saves the manufacturing process cost , and when the arc is generated, it has the functions of magnetic blowing and ...
