FIG. 2B is a cross-sectional view of the electrical connector structure of FIG. 2A along the cross-sectional line A-A. At the same time, right-angle coordinates X-Y-Z are provided to facilitate component description. Please refer to FIGS. 1, 2A and 2B at the same time. In this embodiment, the electrical connector structure 100 includes an insulating body 110 and a plurality of conductive terminals 120. The insulating body 110 has a base 112 and a tongue 114. The tongue 114 has a plurality of hollow portions 114a and a plurality of stop portions 114d, and the stop portion 114d is located at the edge of the hollow portion 114a. The conductive terminals 120 are arranged on the base 112 and extend to the tongue 114. Some of the conductive terminals 120 respectively have elastic portions 121, which have elastic forces along the Z-axis, so that they can be restored to their original shape after being pressed to be connected to the electrical connector (not shown). (Shown) the conductive terminals remain in contact with each other. In this embodiment, the elastic portions 121 are respectively exposed from the hollow portion 114a and protrude from the tongue 114, and the end 121c of the elastic portion 121 abuts against the corresponding stop portion 114d.

Furthermore, the insulating body 110 further has a plurality of recesses 114b located on the tongue 114, and the stop portion 114d is located between the recess 114b and the hollow portion 114a, and the conductive terminal 120 further has a plate-shaped portion 122, and the plate-shaped portion 122 respectively The tongue 114 extends from the tongue 114 to the recess 114 b and exposes the tongue 114 from the recess 114 b. The arrangement direction of the recess 114 b, the arrangement direction of the hollow portion 114 a, and the arrangement direction of the stop portion 114 d are parallel to each other (all parallel to the X axis). On the other hand, the tongue 114 also has a plurality of ribs 114c, which are alternately arranged along the X-axis with the hollow portions 114a. The plate-shaped portions 122 respectively extend along the Y-axis within the ribs 114c, and the stop portion 114d connects these ribs. 114c.

Furthermore, referring to FIG. 2B, the conductive terminal 120 of this embodiment can be substantially further divided into a root portion 123, a plate-shaped portion 122, and an elastic portion 121 according to its characteristics. Some of the conductive terminals 120 have root portions 123 and elastic portions. The remaining conductive terminals 120 have a root portion 123 and a plate-shaped portion 122. The conductive terminals 120 are arranged according to their different electrical definitions, and then combined with the insulating body 110. For the conductive terminal 120 having the elastic portion 121, the protruding direction of each elastic portion 121 is toward the positive Z-axis direction away from the tongue 114, and the stop portion 114d is stopped in the protruding direction of the elastic portion 121, that is, The purpose of the stop portion 114d is to confine the end 121c of the elastic portion 121 within the hollow portion 114a, and prevent the end 121c from hanging above the tongue 114.

In other words, in the electrical connector structure 100 of this embodiment, the stop portion 114d of the insulating body 110 at the edge of the hollow portion 114a can provide a stop to the elastic portion 121 of the conductive terminal 120 extending to the hollow portion 114a, thereby avoiding the elastic portion. 121 continues to extend in the positive Z-axis direction so that its end 121c protrudes from the tongue 114. In this way, when the electrical connector structure 100 is mated with another electrical connector (not shown) along the Y axis, the elastic portion 121 of the conductive terminal 120 will not be connected to the other electrical connector due to the end 121c protruding from the tongue plate 114 The structural interference is generated, so that the protection effect can be provided to both sides of the electrical connector, and the electrical stability during the mating can be maintained.

Fig. 3 is an assembly diagram of the electrical connection structure. 4A and 4B respectively illustrate schematic diagrams of the electrical connector structure in different states. Please refer to FIG. 3, FIG. 4A, and FIG. 4B at the same time, and the process of forming the elastic portion 121 as shown in FIG. 2B is provided below. In this embodiment, the conductive terminal 120 is formed by stamping and forming a metal plate. The plurality of conductive terminals 120 shown are substantially attached to the strips B1 and B2, and then combined with the insulating body 110 to form, and finally According to requirements, the conductive terminal 120 is separated from the material strips B1 and B2. Here, the insulating body 110 and the conductive terminal 120 on the right side of FIG. 3 are separated in advance to facilitate the identification of structural differences.

Please refer to FIG. 2B again. It should also be mentioned that, in the conductive terminal 120 having the elastic portion 121 in this embodiment, the elastic portion 121 essentially has a first arc section 121a and a second arc section 121a protruding from the tongue plate 114. The arc-shaped section 121b, and the first arc-shaped section 121a is adjacent to the end 121c and the second arc-shaped section 121b. As shown in FIG. 2B, the curvature of the first arc section 121a is greater than the curvature of the second arc section 121b, that is, the curvature radius R3 of the first arc section 121a is smaller than the curvature radius R1 of the second arc section 121b. Since the height h1 of the first arc section 121a relative to the tongue plate 114 is greater than the height h2 of the second arc section 121b relative to the tongue plate 114, when the electrical connector structure 100 is docked with another electrical connector (not shown) along the Y axis When shown), part of the conductive terminals of the other electrical connector will substantially abut on the first arc-shaped section 121a.

Please refer to FIGS. 4A and 4B, which illustrate the process of pressing the conductive terminal 120 into the hollow portion 114a so that the end 121c abuts against the stop portion 114d. In FIG. 4A, the insulating body 110 and the conductive terminal 120 are combined but not yet performed. In the riveting state, FIG. 4B is the state in which the riveting is being performed, and after the riveting process, the state is shown in FIG. 2B.

In this embodiment, the radius of curvature R1 of the second arc-shaped section 121b shown in FIGS. 4A and 4B is smaller than the radius of curvature R2 of the second arc-shaped section 121b shown in FIG. During the process, sufficient deformation must be reserved so that the riveting pressure F1 is provided to press the elastic portion 121 into the hollow portion 114a in the process shown in FIG. 4B, and the riveting pressure F2 is also provided in the second arc shape. The section 121b deforms it again, and the second arc 121b with the radius of curvature R1 is subjected to the riveting process to become the second arc section 121b with the radius of curvature R2 (as shown in FIG. 2B), wherein the radius of curvature R2 is greater than the radius of curvature. R1, that is, the effect of the riveting pressure F2 on the second arc-shaped section 121b is to transform it from a state of greater curvature to a state of less curvature.

At the same time, once the second arcuate section 121b is compressed and deformed as shown in FIG. 2B, this also means that the elastic portion 121 will deform and extend in the negative Y-axis direction, and the end 121c of the elastic portion 121 will therefore extend into To the bottom of the stopper 114d. Since the elastic portion 121 of the conductive terminal 120 is stamped and formed as shown in FIG. 3, it has an elastic force that causes it to move upward (toward the positive Z-axis direction). After pressing into the hollow portion 114a, the elastic portion 121 still retains the elastic force toward the positive Z-axis direction. However, at this time, it is limited by the stop portion 114d and interferes with each other. Therefore, the elastic portion 121 is confined within the hollow portion 114a. The tongue plate 114 is not ejected.

In summary, in the above-mentioned embodiment of the present invention, the electrical connector structure extends the elastic part of the conductive terminal from the base part of the insulating body to the hollow part of the tongue plate, and then further makes the end of the elastic part abut against The stop part is positioned at the edge of the hollow part, so that although the elastic part is exposed to the hollow part and protrudes above the tongue due to elasticity, the end of the elastic part will abut the stop part and effectively prevent The elastic part is completely warped above the tongue plate. This allows the stop portion of the insulating body to provide a limiting effect on the conductive terminals, so as to avoid damage to the conductive terminals such as misalignment or even reflex due to structural conflicts when the electrical connector structure is mated with another electrical connector, thereby effectively The ground improves the structural stability after the conductive terminal is combined with the insulating body.
