The male terminal provided by the utility model effectively solves the problem that the shell 2 and the contact part 1 are easily separated in the prior art, resulting in poor stability of the male terminal.

[0031] In some embodiments, as shown in Figures 1 to 3 The shell 2 has a receiving cavity 23, and a first assembly hole 24 and a second assembly hole 25 that are in communication with the receiving cavity 23. The contact main body 12 is located in the receiving cavity 23, so that the shell 2 can protect the contact main body 12. The first assembly hole 24 and the first mounting hole 121 are in communication, and the second assembly hole 25 and the second mounting hole 122 are in communication. The first connecting structure 21 is connected to the inner wall of the first assembly hole 24, and the second connecting structure 22 is connected to the inner wall of the second assembly hole 25. In this way, the first connecting structure 21 and the second connecting structure 22 are connected to the shell 2.

[0032] Specifically, the first assembly hole 24 and the second assembly hole 25 are arranged at the two ends of the shell 2 in a direction perpendicular to the insertion direction of the contact terminal 11.

[0033] In the embodiment, as shown in Figure 3 The first connecting structure 21 includes a first bent plate 211 and a second bent plate 212. The first bent plate 211 and the second bent plate 212 are connected to the two inner walls of the first assembly hole 24, respectively, and extend towards the receiving cavity 23. The first bent plate 211 and the second bent plate 212 are inserted into the first mounting hole 121 and connected to the two inner walls of the first mounting hole 121, respectively.
