Example Embodiment

[0046] The present invention will be further described below with reference to the drawings and embodiments.

[0047] Refer to figure 1 , figure 2 As shown, the present invention provides a method for welding a seat plate assembly, which includes an induction coil passing a high-frequency current and sheathing the seat plate assembly 1 with filler solder, and using the heat generated by the induction coil to melt the filler solder pair The seat plate assembly 1 is sealed and welded. In this embodiment, the induction coil with high-frequency current makes full use of the two major effects (skin effect and proximity effect) in high-frequency heating to stimulate the thermal effect of the welding parts when they are induced, and improve the soldering process The permeability, avoid welding cavities and discharge welding excess, improve the mechanical strength and sealing performance of the weld, and improve the performance index of the whole product.

Abstract

The invention relates to a soldering method of a seat plate assembly, an induction coil for soldering and a manufacturing method of the induction coil. The method comprises the following steps of sheathing the induction coil conducted with high-frequency current onto the seat plate assembly with filling solder, and using the heat generated by the induction coil to melt the filling solder so as to seal and solder the seat plate assembly. The method has the advantage that by adopting the high-frequency induction principle, the movement of molecules in a soldering piece is simulated, the heat is generated in the metal to melt the soldering material, and then the soldering piece is welded, so the number of soldering defects is little, the investment cost of equipment is less, the soldering cost is low, the operability is good, and the body health of operators is favorable.

Description

technical field [0001] The present invention relates to the field of welding technology, and more specifically relates to a welding method of a seat plate assembly, an induction coil used for welding and a manufacturing method thereof. Background technique [0002] With the rapid development and progress of various technical fields in the electromechanical industry, the technical specifications of circuit breakers and contactors for power switching in various power control systems are also getting higher and higher. The original high current, high voltage Unsealed circuit breakers and contactors can no longer meet the requirements of use. Therefore, various sealed circuit breakers and contactors have been widely used in various electromechanical industries with superior technical performance, and their performance is superior in aviation and aerospace. appear particularly prominent. Most of the components in the contact seat plate components of various sealed circuit breake...
