【Background technique】

With the rapid development of the electronics industry, various high-tech products are constantly emerging, and video electronic products such as computers and TVs are experiencing an era of rapid development. The lighting devices on the display screens of such electronic products currently on the market need an electrical connection terminal for connecting to a circuit board. The electrical connection terminal includes a main body and a welding portion extending vertically from the end of the main body. The welding portion is located on one side of the main body, and the welding portion is unilaterally fixed to the entire electrical connection terminal. Moreover, the main body of the electrical connection terminal is connected to the connector connected to the lighting device. Since the main body is U-shaped and flat as a whole, a large insertion and extraction force is required between the two, and there is a large gap between the soldering part and the circuit board. A great impact was exerted. Therefore, the electrical connection terminal with an unstable structure tends to be inclined when it is welded to the circuit board, and the electrical connection terminal whose main body is subject to a large insertion force is also prone to loosening after welding with the circuit board, resulting in an unstable connection.

Therefore, in view of the aforementioned shortcomings of the electrical connection terminal, it is necessary to design an electrical connection terminal that is more stable in connection with the circuit board and less prone to tilting during soldering to meet the needs of the development of the electrical connection terminal technology.

【Detailed ways】

As shown in Fig. 1, Fig. 2 and Fig. 3, the electric connection terminal 1 of the present invention is used for connecting on the circuit board 2, and the electric connection terminal 1 comprises a main body 11, a welding part 12 extending from the main body 11 and In the supporting part 13 opposite to the welding part 12, the welding surface of the welding part 12 and the supporting surface of the supporting part 13 are located on the same plane. The electrical connection terminal 1 with the welding portion 12 and the support portion 13 is not easy to tilt when connected to the circuit board 2, and will not cause defective soldering, and can withstand a certain impact force, ensuring that the electrical connection terminal 1 and the circuit board 2 are not easy to loosen after welding. The connection is stable.

The main body 11 of the electrical connection terminal 1 is U-shaped and flat as a whole. The main body 11 is connected to the connector (not shown) connected to the lighting device. Due to the shape of the main body 11, the main body 11 is connected to the lighting device. A large plugging force is required between the connectors, and this plugging force further produces a large impact force on the soldering portion 12 and the circuit board 2, resulting in an unstable connection between the two. The welding part 12 and the supporting part 13 are horizontally long flat rectangles, which are more conducive to the stable connection between the electrical connection terminal 1 and the circuit board 2. In the length direction, the welding part 12 is longer than the supporting part 13, and the welding part 12 plays a major role. The supporting part 13 plays an auxiliary balancing role. The welding portion 12 extends from the lower end of the main body 11 in a direction perpendicular to the main body 11, and the supporting portion 13 extends from the lower end of the main body 11 in a direction perpendicular to the main body 11, and the extending direction of the welding portion 12 is opposite to that of the supporting portion 13. The welding part 12 and the supporting part 13 constitute a balanced structure. The welding part 12 has a welding surface 121, and the supporting part 13 has a supporting surface 131. The welding surface 121 and the supporting surface 131 are located on the same plane, which ensures the stability when welding with the circuit board 2, makes welding easier, and improves both The ability to withstand impact force avoids loosening after welding.

When the electrical connection terminal 1 is assembled with the circuit board 2, the main body 11 of the electrical connection terminal 1 passes through the circuit board 2. On one side, the welding surface 121 and the circuit board 2 are welded by welding technology, and the supporting surface 131 is in contact with the circuit board 2, which plays a role of supporting balance and reduces the impact force on the welding surface. If necessary, the supporting surface 131 and the circuit board can also be connected The circuit board 2 is welded together by soldering technology.
