In this embodiment, the male "convex" type slot 1111 is surrounded by ribs extending laterally from the inner walls of the two sides of the male terminal slot 111 and a groove on the bottom surface. During assembly, the male end limiting wing 1023 is located in the wide end of the male end 'convex' groove 1111 to form upper and lower limiting, and the narrow end of the male end 'convex' groove 1111 is used for forming a certain space for the male end elastic buckle 1022 to give way, so that the male terminal elastic sheet 10 can smoothly and easily slide and be installed into the male end 'convex' groove 1111. During the assembly process, when the male end elastic buckle 1022 passes over the step 112 and then elastically returns, i.e. expands to a natural state, the male end elastic buckle forms a reverse limit with the step 112, so as to prevent the male terminal elastic sheet 10 from being separated along the reverse direction of sliding loading.
Similar to the principle of the male terminal connector 1, the female terminal wire holder 21 corresponds to the female terminal spring plate 20, and is provided with a female terminal wire slot 211 which is separated from each other, the female terminal wire slot 211 is communicated with the socket 22, and the female terminal spring plate 20 is inserted from the female terminal wire slot 211 and penetrates into the socket 22.

During assembly, the female end elastic buckle 2021 passes over the clamping table 212 and then elastically resets to be unfolded to a natural state, and forms reverse limit with the clamping table 212.
As shown in fig. 7, the male terminal socket 11 and the plug pin 12 form a fault offset in the height direction, and in this embodiment, since the male terminal socket 11 and the plug pin 12 form a fault offset in the height direction, the male terminal wire slot 111 and the "convex" type channel 121 also form a fault offset in the height direction. The outer contour of the male terminal wire slot 111 extends toward the plug pin 12, a male terminal wire blind hole 1112 is formed in the male terminal wire slot 111 for plugging a wire, and the male terminal wire portion 101 is bent toward the male terminal wire blind hole 1112 for contact communication with the wire. The male terminal wire connecting part 101 and the male terminal connecting part 102 are bent to form an acute angle, namely, the tail end of the male terminal wire connecting part 101 faces the male terminal wire blind hole 1112, when a wire is inserted, the male terminal wire connecting part 101 forms an inclined plane, so that the wire is easy to insert, and the wire is pulled out from the opposite direction to form a propping force, so that the connection strength of the wire is ensured, and screw-free installation is realized.
Meanwhile, as shown in fig. 1, the outer contour of the male terminal wire holder 11 faces the forming limit block 113 of the female terminal connector 2, and when the male terminal wire holder is inserted in place, the end face of the inserting seat 22 abuts against the limit block 113. In order to ensure the connection strength of the male terminal connector 1 and the female terminal connector 2, two sides of the male terminal connector 1 are provided with raised compression blocks 13, and the plug pins 12 are in interference fit with the plug sockets 22 through the compression blocks 13.
As shown in fig. 10, the female terminal holder 21 and the socket 22 are also staggered in height, and unlike the male terminal fitting 1, a blind hole for plugging a wire is no longer required to be provided in the female terminal groove 211 of the female terminal fitting 2. The bus bar slot 211 ensures that the mating face 2012 of the bus bar portion 201 can be bent back into the slot. In this embodiment, the welding surface 2011 of the female terminal connection portion 201 is substantially perpendicular to the female terminal connection portion 202, and the plugging surface 2012 is substantially perpendicular to the welding surface 2011, i.e. the female terminal connection portion 202, the welding surface 2011 and the plugging surface 2012 enclose a "冂" structure. The soldering surface 2011 is used for soldering with a wire.
The above examples are only for illustrating the present invention and are not to be construed as limiting the invention. Variations, modifications, etc. of the above-described embodiments are intended to fall within the scope of the claims of the present invention, as long as they are in accordance with the technical spirit of the present invention.
