According to the rapid development of today's electronic technology, the type of computer has evolved from a desktop computer to a small-sized, portable notebook computer, and it is common in all corners of society. When users want to transmit data signals or When connecting with other peripheral devices, the so-called peripheral device interface is required, and the peripheral device interface on the market is the most common and widely used by the public, and the universal serial bus (USB) is still the mainstream.

Furthermore, as electronic devices such as notebook computers and ultra-thin notebook computers tend to be light, thin, short, and small, in order to reduce the size of the electronic device, the electrical connectors on the internal circuit board of the electronic device are required. Small and precise, the overall structural strength needs to be strengthened, and the universal serial bus connector is also upgraded from the early specification type (USB2.0) to the higher-order specification (USB3.0), and its practical functions are enhanced. Application range.

However, the assembly of the plurality of conductive terminals of the conventional electrical connector is mostly a barbed structure extending on the metal sheet body and engaging the terminal groove of the plastic body by the barb structure. At the inner wall surface, as the transmission speed of the conventional electrical connector is greatly increased, the number of conductive terminals is increased and the distribution is dense. This will cause the plastic body to be easily damaged by excessive extrusion of the conductive terminals or the convexity of the surface. Therefore, the holding force of the conductive terminal is reduced. When the conventional electrical connector is docked with another electrical connector, the conductive terminal is subjected to the pushing force, and there is a risk of exiting the terminal slot, so that the assembly requirement becomes high. It is easy to cause instability of the overall structure, and the assembly space required for assembling the plurality of conductive terminals on the plastic body is large, and will occupy a certain volume, so that the overall thickness of the conventional electrical connector cannot be made thinner and thinner, Those who work in this industry are redesigned to effectively solve them.

Therefore, the new creators, in view of the problems and shortcomings of the conventional electrical connectors, collected the relevant materials through multi-party evaluation and consideration, and continuously tried and modified the years of R&D experience in the industry to design such electrical connectors. The new generation of terminal modules.

The main purpose of the present invention is to connect the first welding portion of the first terminal group and the second welding portion of the second terminal group to the material belt, and integrally form the seat body by using plastic injection in a mosaic manner, and each first The first contact portion of the terminal group and the second contact portion of the second terminal group are exposed surfaces exposed on the top of the base body, so that the material can be broken and then the finished product, so that the first welding portion of the first terminal group and the first The second welded portion of the two-terminal group passes through the wall surface at the two sides of the seat body, and the overall height is reduced and thinner, so as to meet the design requirements of thin, light and short products, the modular structure design of the terminal can be effective not only effective The man-hour and cost of the assembly method are saved, and the structure in which the strip is integrally formed with the first terminal group and the second terminal group is relatively complete, which can effectively reduce the inconvenience and difficulty in the design of the mold, and at the same time ensure the quality of the overall manufacturing. The yield is suitable for mass production, thereby achieving the effects of structural stability, mass production, and low cost.
