Technical Field
[0001] The utility model relates to the technical field of signal terminals, in particular to a signal terminal connection structure with firm welding. Background Art
[0002] Signal terminals are electronic components that are mainly used to connect circuit cables or wires. They can connect circuit cables, fix circuit cables, simplify wiring operations, reduce maintenance difficulties, and improve equipment reliability and safety. There are many types of signal terminals, including single-hole, double-hole, socket, hook and other forms. There are also different options for materials such as copper-plated silver, copper-plated zinc, copper, aluminum, and iron. These terminals can be used to transmit electrical signals or conduct electricity, and are widely used in electronic equipment manufacturing, communications, power, industrial control, aerospace and other fields.
[0003] However, the signal terminal in the prior art has a simple structure. When the terminal pin is welded to the connecting end, it is relatively smooth and has a small contact area with the solder paste. When subjected to external impact, the terminal falls off due to excessive stress, which is inconvenient to use. Utility Model Content
[0004] The utility model aims to provide a signal terminal connection structure with strong welding, which has the characteristics of high welding strength, making the signal terminal welding more stable and effectively reducing the probability of the signal terminal falling off.

[0006] In order to facilitate the welding and fixing of the signal terminal, as a preferred signal terminal connection structure with firm welding of the utility model, the signal terminal body and the terminal pin are vertically arranged.
[0007] In order to improve the overall strength of the signal terminal, as a preferred signal terminal connection structure with firm welding of the utility model, the signal terminal body and the terminal pin are an integrated structure.
[0008] In order to increase the contact area between the solder paste and the terminal pins, as a preferred signal terminal connection structure with firm welding of the utility model, the plurality of protrusions are distributed in a rectangular array.

[0010] In order to prevent the bumps from falling off, as a preferred signal terminal connection structure with firm welding of the utility model, the plurality of bumps and the terminal pins are an integrated structure.
[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0012] The bottom of the terminal foot of the signal terminal is fixedly connected with multiple protrusions. When welding, the solder paste is connected to the outer walls of the multiple protrusions and the bottom surface of the terminal foot. Compared with the smooth bottom surface of the traditional signal terminal foot, the contact area between the solder paste and the terminal foot is effectively increased, thereby improving the welding firmness. At the same time, a through hole is opened through the connection between the signal terminal body and the terminal foot. The setting of the through hole makes it easy for the solder paste to climb to the upper end of the terminal foot through the through hole during welding, thereby further improving the welding strength, making the signal terminal welding more stable, and effectively reducing the probability of the signal terminal falling off.
