On the other hand, the second structure 230 further has a plurality of second limit protrusions 232 at the top thereof, and abuts against the first structure 210, and the abutting direction of the second limit protrusions 232 with the first structure 210 is orthogonal to the X-Y plane along the Z axis.

Here, as shown in fig. 3B and 3C, the second limit projection 232 located on the left and right sides abuts against the first assembly portion 215, and the second limit projection 232 located at the center has two notches 233 and abuts against the second assembly portion 216.
In summary, in the above embodiments of the present invention, the electrical connector is formed by matching a plurality of first structures with a plurality of elastic terminals, wherein the corresponding first structures and elastic terminals form basic units, and the basic units are used as basic components of the electrical connector, that is, the electrical connector is formed by a single basic unit, or formed by assembling a plurality of basic units like building blocks.
When the first structure body and the second structure body are combined, the first structure body and the second structure body are matched with each other to assemble the first structure body together, and the elastic terminals are arranged on a plane along an axial direction to form a plane type connecting terminal structure for requirements. In some embodiments, the assembled first structure body needs to be added with a second structure body to improve the structural wall, so as to ensure that the elastic terminals on the first structure body are located on the same plane and have the same height, thereby meeting the use requirement of the board-to-board connector.
Therefore, the user can correspondingly assemble the electric connectors with different specifications by the combination method, thereby effectively simplifying the complex processes in the design and production processes and effectively improving the production efficiency.
