Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figs. 1-3 As shown, a board-to-board connector with a locking structure includes a female connector 1, a male connector 2 inserted above the female connector 1, a base plate 3 fixedly mounted on opposite sides of the female connector 1 and the male connector 2, auxiliary mechanisms 4 provided at the front and rear edges of the upper surface of the female connector 1, protrusions 5 provided at the front and rear edges of the lower surface of the male connector 2, connecting mechanisms 6 fixedly mounted on the upper sides of the left and right ends of the outer surface of the female connector 1, and plug-in parts 7 installed on the lower sides of the left and right ends of the outer surface of the male connector 2.

[0021] By adopting the above technical solution, the female connector 1 and the male connector 2 can be plugged in to connect the substrate 3.

[0022] Furthermore, the auxiliary mechanism 4 includes grooves 401 on both the front and rear sides of the upper surface of the female head 1. A thrust spring 402 is fixedly installed below the inner surface of the groove 401, and the same movable piece 403 is fixedly installed at the upper end of the thrust spring 402. The size of the groove 401 matches the protrusion 5, and the movable piece 403 is slidably disposed inside the groove 401.

[0023] By adopting the above technical solution, the protrusion 5 will be inserted into the groove 401, thereby improving the installation accuracy of the female head 1 and the male head 2, and allowing for a more intuitive observation from the outside whether the connection is precise.

[0024] During disassembly, the thrust spring 402 pushes the protrusion 5 through the movable piece 403, thereby applying an upward force to the male head 2, which facilitates manual disassembly.

[0025] Furthermore, the connecting mechanism 6 includes connecting blocks 601 fixedly installed on both the left and right sides of the outer surface of the female head 1. Each connecting block 601 has an insertion port 602 at its upper end and a positioning hole 603 on the side of the surface of the connecting block 601 away from the female head 1.

[0026] The plug-in part 7 comprises elastic piece buckles 701 fixedly installed on both sides of the outer surface of the male head 2, and limit blocks 702 are fixedly installed on the side of the elastic piece buckles 701 away from the male head 2; the elastic piece buckles 701 are shaped as vertical "V" characters, and the lower surfaces of the limit blocks 702 are shaped as inclined surfaces.

[0027] Through the above technical solution, when the female head 1 and the male head 2 are plugged in, the elastic piece buckles 701 are inserted into the sockets 602 of the connecting blocks 601, and the inclined surfaces push the elastic piece buckles 701 to shrink with the limit blocks 702; when the limit blocks 702 are lowered to be flush with the positioning holes 603, the limit blocks 702 are inserted into the positioning holes 603 under the elastic action of the elastic piece buckles 701, so that the elastic piece buckles 701 are fixed with the connecting blocks 601.

[0028] Working principle: when the plate-to-plate connector with the locking buckle structure is used, first, when the substrate 3 is connected by the female head 1 and the male head 2, the protrusions 5 are plugged into the corresponding grooves 401, so as to improve the installation precision of the female head 1 and the male head 2, and after installation, the movable pieces 403 are pressed to compress the push spring 402; when the female head 1 and the male head 2 are plugged in, the elastic piece buckles 701 are inserted into the sockets 602 of the connecting blocks 601, and the inclined surfaces push the elastic piece buckles 701 to shrink with the limit blocks 702; when the limit blocks 702 are lowered to be flush with the positioning holes 603, the limit blocks 702 are inserted into the positioning holes 603 under the elastic action of the elastic piece buckles 701, so that the elastic piece buckles 701 are fixed with the connecting blocks 601; when it is needed to disassemble, the limit blocks 702 are moved out of the positioning holes 603 by manually pressing the elastic piece buckles 701; at this time, the push spring 402 pushes the protrusions 5 through the movable pieces 403, so as to apply an upward force to the male head 2 to assist in separating the male head 2 from the female head 1, and the disassembly is completed; this is the working principle of the plate-to-plate connector with the locking buckle structure.
