Detailed ways:

In order to enable the review committee to have a further understanding of the purpose, features and functions of the present utility model, the preferred embodiments are hereby given in detail with the accompanying drawings as follows:

Please refer to Figures 1 to 6, the utility model is related to the structure of a wire-connected electrical connector. A receiving portion 11 protrudes from the end of the welding wire, and the receiving portion 11 is integrally formed or combined with the insulating main body 10. Here, an integral structure is preferred to simplify processing and assembly. The receiving part 11 protrudes and widens laterally, is wider than the insulating body 10, and is fan-shaped; the receiving part 11 is provided with terminal grooves 12, and the terminal grooves 12 are opened symmetrically on the upper and lower sides of the receiving part 11, and the terminal grooves 12 are evenly spaced.

As shown in FIG. 4 , the soldering portion 21 of the terminal is properly bent and arranged, and is correspondingly arranged in a fan-shaped distribution. When assembled, it is accommodated in the terminal groove 12 for soldering with wires. In this embodiment, the terminal welding portion 21 is flattened and widened relative to the bent portion, increasing the welding surface, improving welding quality, and improving signal transmission performance.

The receiving part 11 protrudes and widens laterally, thereby widening the receiving surface, ensuring sufficient spacing between the terminal welding parts 21, and meeting the requirements for widening the welding part 21. The terminal groove 12 on the receiving part 11 is for the terminal welding part 21 to accommodate. Provide welding space between the welding part 21 and the wire, and effectively separate the welding part 21 to avoid short circuit. The structure facilitates welding operations, improving efficiency and assembly quality.
