Embodiment Construction
[0066] Description of the preferred embodiment
[0067] Preferred embodiments of the present invention are described below with reference to the accompanying drawings.
[0068] figure 1 is a perspective view showing a welded structure 10 according to a first preferred embodiment of the present invention, wherein a part of the structure is omitted.
[0069] refer to figure 1 , the soldered structure 10 includes a conductive plate 11 forming a circuit. The conductive plate 11 is a substantially strip-shaped plate having electrical conductivity. By bending the conductive plate at an angle not equal to 0° or 180°, preferably 90°, with respect to the base portion, the front end portion of the conductive plate 11 forms a solderable portion 11a which stands upright from the conductive plate 11 Or protrude from the conductive plate 11. In the following description, the side on which the solderable portion 11a of the conductive plate 11 stands is referred to as the front side, a...

Abstract
The objective of the invention is to provide a welding structure for generating an arc at a stable position and performing arc welding to an electronic element and a conductive plate with reproducibility without damaging the electronic element, and a welding method using the welding structure. A welding structure (10) includes a welding part (11a) formed by bending a tip part of a conductive plate (11). An apex part (11c) is formed on the welding part (11a). A slit (11d) is formed from a left oblique side (11b) toward the center in the plate width direction of the welding part (11a), and a lead part (12a) is accommodated in the slit (11d). A melting part (11e) is formed between the slit (11d) and the tip part of the welding part (11a) including the apex part (11c). When an electrode (D) of an arc welding machine generates the arc to the tip of the welding part (11a), the arc is directed to the apex part (11c) and melts the melting part (11e) to connect the lead part (12a) to the welding part (11a).
Description
technical field [0001] The present invention relates to a welding structure for welding a lead part of a device to a conductive plate by an electric arc, and a welding method using the welding structure, wherein the device refers to an electric device or an electronic device. Background technique [0002] Generally speaking, an electronic device used in an electric circuit is provided with a wire part electrically connected to the circuit, and the wire part is connected to a conductive plate such as a bus bar to form a circuit. Traditionally, this connection has been accomplished by spot welding the junctions of the wire sections to the conductive plates. This soldering method realizes the electrical connection between the lead part of the electronic device and the conductive plate by melting a part of the conductive plate to wrap the lead part and fix the lead part on the conductive plate. [0003] The welding beam joint structure disclosed in Japanese Patent Application L...
