Terminal structure and method of attaching the same

Abstract

The invention discloses a terminal structure, fixed on a circuit board to make a lead wire connected with the circuit board, and comprising a fixed part and a junction part, where the fixed part is fixed on the circuit board, and the junction part is connected with the fixed part and connected with the lead wire. And the invention also discloses a terminal structure's connecting method.

Description

technical field [0001] The invention relates to a terminal structure and a connection method thereof, in particular to a terminal structure and a connection method for indirect electrical connection between a circuit board and a conductive wire. Background technique [0002] see Figure 1A and Figure 1B The traditional method of connecting a circuit board 6 such as a brushless motor to a conductive wire 5 (such as an enameled wire) is to directly solder and fix the enameled wire 5 on the circuit board 6, or pass through the through hole of the circuit board 6 and use The solder s is fixed by soldering. However, the traditional connection method tends to produce bends circled by A and B as shown in the figure, so that the enameled wire 5 is easily broken due to vibration or pulling, or the pad material on the circuit board 6 ( pad) warping causes the enameled wire 5 to come off. Generally speaking, the above connection method is suitable for ordinary grade enameled wire t...

Problems solved by technology

However, the traditional connection method tends to produce bends circled by A and B as shown in the figure, so that the enameled wire 5 is easily broken due to vibration or pulling, or the pad material on the circuit board 6 ( pad) warping causes the enameled wire 5 to fall off

Generally speaking, the above connection method is suitable for ordinary grade enameled wire through which small current passes. When using wire (PEW+NY), it is impossible to directly remove the covering layer of the enameled wire 5 by heating in a tin furnace, but additional chemicals or knives are required to remove the covering layer, which not only causes extra man-hours and processes, but also increases the production process. uncertain factors

Moreover, forced welding in the existing way may easily cause the connection between the circuit board 6 and the enameled wire 5 to be insufficiently stable, resulting in a reduction in product reliability.
