[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without creative work fall within the scope of protection of the present application.

[0025] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the term "and / or" in the present application is only to describe the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can mean that there are three cases of A alone, A and B together, and B alone. In addition, the character " / " in the present application generally represents an "or" relationship between the associated objects without special explanation.

[0026] The following will be described in detail with reference to the drawings in the embodiments of the present application. Figures 1-9 The present application will be further described.

[0027] Reference will be made to Figure 1 and Figure 2 A male connector provided by the present application has a first direction X, a second direction Z and a third direction Y intersecting with each other. In one example, the first direction X, the second direction Z and the third direction Y form a space rectangular coordinate system.

[0028] The male connector comprises a housing 1, a terminal assembly 2 arranged in the housing 1, and a primary locking member 3, a secondary locking member 4 and a tertiary locking member 5 for fixing the terminal assembly 2.

[0029] Reference will be made to Figure 2 and Figure 3 For the housing 1, the housing 1 is in the shape of a rectangular block as a whole, and has at least one accommodating cavity 10 inside. In one example, three accommodating cavities 10 are provided, which are arranged at intervals along the third direction Y, and the cross section of the accommodating cavities 10 is circular. Each of the accommodating cavities 10 is arranged through the housing 1 along the first direction X. An insertion port 11 is formed at one end of the accommodating cavities 10 in the first direction X, and is used for inserting and mounting the terminal assembly 2. A fixing port 12 is arranged on the housing 1 along the second direction Z and communicates with the accommodating cavities 10, and is used for limiting the terminal assembly 2 by the secondary locking member 4 after the secondary locking member 4 is mounted on the housing 1.

[0030] Reference will be made to Figure 2 and Figure 4For the terminal assembly 2, the terminal assembly 2 includes a cable 21 and a shielding shell 22 wrapped outside the cable 21, the terminal assembly 2 is in a cylindrical shape as a whole, and the terminal assembly 2 is also provided with three, and the terminal assembly 2 is arranged in the accommodating cavity 10 one by one. The terminal assembly 2 is inserted into the accommodating cavity 10 along the first direction X by the plug-in port 11, and the terminal assembly 2 has a buckle portion 20. Specifically, the shielding shell 22 includes a first section 221, a second section 222 and a third section 223 in sequence along the first direction X, wherein the outer diameter of the second section 222 is smaller than the outer diameter of the first section 221 and the outer diameter of the third section 223, and the difference between the second section 222 and the third section 223 and the first section 221 forms the buckle portion 20. It can be understood that the buckle portion 20 refers to the annular groove formed by the difference between the second section 222 and the third section 223. After the terminal assembly 2 is inserted into the accommodating cavity 10, the primary locking member 3 and the secondary locking member 4 are buckled with the buckle portion 20, so that when the terminal assembly 2 slides along the first direction X, the primary locking member 3 and the secondary locking member 4 block the third section 223 or the first section 221, thereby limiting the sliding trend of the terminal assembly 2 along the first direction X, so as to ensure the fixation of the terminal assembly 2.

[0031] Referring to Figure 2 , Figure 3 and Figure 5 , for the primary locking member 3, the primary locking member 3 is elastically arranged in the inner wall of the shell 1, and the primary locking member 3 is buckled with the buckle portion 20.

The specific principle is that the terminal assembly 2 is inserted into the accommodating cavity 10 from the plug-in port 11 along the first direction X, and the third section 223 will contact the primary locking member 3 during the advancing process, and the primary locking member 3 will be extruded and deformed towards the outside, and after the third section 223 completely passes the primary locking member 3, the primary locking member 3 is buckled in the buckle portion 20, and when the terminal assembly 2 retreats along the first direction X, it will be limited by the third section 223, thereby completing the primary fixation of the terminal assembly 2.

[0032] Referring to Figure 6 , Figure 7 and Figure 8 , for the secondary locking member 4, the secondary locking member 4 is buckled with the fixed port 12, the secondary locking member 4 is buckled with the buckle portion 20, and the secondary locking member 4 is buckled and fixed between the shell 1.

[0033] The terminal assembly 2 is installed in the accommodating cavity 10, the first locking member 3 and the second locking member 4 are respectively buckled with the buckle portion 20, thereby forming a double fixed constraint effect, and the terminal assembly 2 is fixed more firmly to ensure the stability of the connection between the terminal assembly 2 and the shell 1. The installation positions of the second locking member 4 and the first locking member 3 are different, the second locking member 4 can be independently buckled with the buckle portion 20 from different directions of the terminal assembly 2 to ensure the reliability of the fixation, and the space occupation can be saved, the compactness of the male connector is improved, the second locking member 4 is detachably connected with the shell 1, and the convenience of the maintenance and installation of the male connector is improved.

[0037] In an example, the hooking protrusions 411 are arranged in two and are spaced apart along the second direction Z, and are staggered in the first direction X. This arrangement can effectively improve the reliability of the connection between the second locking member 4 and the shell 1, thereby ensuring the fixation of the second locking member 4 to the terminal assembly 2. Correspondingly, referring to Figure 2 The hooking groove 101 is provided in an L shape and is used for the hooking cooperation of the two hooking protrusions 411.

The clamping part 42 is in the shape of a whole circular arc C and has an opening facing the shell 1. The clamping part 42 is arranged one by one corresponding to the terminal assembly 2, so that one clamping part 42 can correspond to one terminal assembly 2 and can be circumferentially matched with the buckle part 20 to comprehensively limit the circumference of the terminal assembly 2, thereby effectively improving the limiting area of the clamping part 42 and the buckle part 20, thereby improving the stability of the limiting of the two.
