Specifically, please refer to FIG. 6 and FIG. 7, when the plug electrical connector 2 is inserted into the cavity 17 of the socket electrical connector 1 through the plug-in interface 11, it is against the first elastic terminals 21 When the electrical contact end 211 is between the multiple second electrical contact ends 311 of the multiple second elastic terminals 31, each first electrical contact end 211 will be forced to move toward the top wall 12, thereby pulling each of the first electrical contact ends. A main body section 212 is elastically deformed, for example, each first main body section 212 will bend toward the bottom wall 13. In the same way, the plurality of second electrical contact ends 311 will also move toward the bottom wall 13 under force, thereby pulling each second body section 312 to produce elastic deformation, for example, each second body section 312 will face the top wall 12 The direction is curved. At this time, since the first terminal base 20 is fitted and fixed to the plurality of slots 151 of the top wall 12 with a plurality of insert blocks 251 correspondingly, the first terminal base 20 and the insulating housing 10 are firmly combined with each other. Therefore, the first The terminal base 20 will not be driven by the elastic deformation of each first body section 212 to move toward the bottom wall 13 and separate from the insulating housing 10, so as to keep the first terminal base 20 in a predetermined position. In addition, due to the first The position of the terminal base 20 can be maintained, so that the first terminal base 20 can further press the second terminal base 30 downward, thereby preventing the second terminal base 30 from being driven downward by the elastic deformation of the second body sections 312 The wall 12 is displaced in the direction to be separated from the insulating housing 10, thereby effectively avoiding affecting the electrical characteristics of the connector (such as contact resistance, insulation resistance, withstand voltage or electromagnetic interference, etc.), and can meet the expected electrical connection effect to improve The quality of the product.

In some embodiments, the inserting block 251 and the slot 151 can also be fitted and fixed to each other in a tight fitting manner. For example, the cross section of the inserting block 251 and the slot 151 can have corresponding shapes, such as square or It has a rectangular shape with the same width up and down, and the minimum tolerance size of the insert block 251 is greater than the maximum tolerance size of the slot 151 and can be tightly fitted to each other to avoid displacement of the insert block 251 relative to the slot 151, and to avoid the first The terminal base 20 and the second terminal base 30 are displaced or separated from the insulating housing 10 due to the elastic deformation of the first elastic terminal 21 and the second elastic terminal 31, which is omitted from the drawing in this embodiment.

Please refer to FIGS. 3, 6 and 7, in this embodiment, the first terminal base 20 includes a front side 22 and a rear side 23 opposed to each other. The front side 22 is close to the insertion port of the insulating housing 10 relative to the rear side 23 11. The position of the second engaging member 25 is preferably adjacent to the rear side 23. Specifically, when each first electrical contact end 211 of each first elastic terminal 21 receives a force toward the top wall 12 and pulls each first body section 212 to produce elastic deformation, the The front side 22 will form a point, so the closer each first body section 212 is to the rear side 23 of the first terminal base 20, the greater the displacement will be. Therefore, the closer the second fitting 25 of the first terminal base 20 is The rear side 23 can more effectively prevent the first terminal base 20 from being driven by the elastic deformation of each first body section 212 to move toward the bottom wall 13.

As shown in FIG. 9, it is a cross-sectional view of the third embodiment of the socket electrical connector of the present invention. The difference between this embodiment and the above-mentioned first embodiment and the second embodiment is that the inserting block 251B of this embodiment is protruding The L-shaped block on the surface of the first terminal block 20, and the top of the insert block 251B has a hook 252B, and the hook 252B extends in the direction of the insertion port 11 of the insulating housing 10, and the slot 151B is located in the insulating housing 10. The opening direction of the slot 151B is toward the assembly port 16, so that when the first terminal block 20 is inserted, the hook portion 252B of the insert block 251B can be inserted into the slot 151B to hook the insulating housing 10 The top wall 12 enables the first terminal base 20 and the insulating housing 10 to be firmly combined and avoid separation.

In some embodiments, the fixing base 40 may be further connected to the bottom wall 13 of the insulating housing 10 to more effectively prevent the second terminal base 30 from being elastically deformed by the second body sections 312 of the second elastic terminals 31 Driven by, it displaces toward the top wall 12 and separates from the insulating housing 10. As shown in FIGS. 3, 6 and 7, in this embodiment, the bottom wall 13 of the insulating housing 10 is provided with a first coupling member 131 on a side away from the insertion port 11, and the first coupling member 131 includes at least one protrusion Rib 132.
