[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] Example: Please refer to Figure 1-7 This utility model provides a technical solution: an electronic connector structure to prevent mis-insertion, including a female shell 1 and a male shell 2. A limiting protrusion 14 is provided on the upper side of the female shell 1, and a limiting protrusion 24 that mates with the limiting protrusion 14 is provided on the upper end of the male shell 2. A female end limiting block 4 and a male end limiting block 3 are respectively snapped onto the outer ends of the female shell 1 and the male shell 2. Figure 2 As shown, overlapping edges are respectively provided on the female rubber shell 1 and the male rubber shell 2 to cooperate with the female end limiting block 4 and the male end limiting block 3, thereby facilitating the engagement of the female end limiting block 4 and the male end limiting block 3. A guide groove 12 is provided at the upper end of the female rubber shell 1, and a guide block 21 for sliding connection inside the guide groove 12 is provided at the upper end of the male rubber shell 2. The provision of the guide groove 12 and the guide block 21 ensures that the front and rear positions of the female rubber shell 1 and the male rubber shell 2 correspond. The provision of limiting protrusion 14 and limiting protrusion 24 can effectively limit the left and right relative positions of the female rubber shell 1 and the male rubber shell 2. It is worth noting that the limiting protrusion 24 cooperating with limiting protrusion 14 is provided with a certain guide slope, which facilitates the insertion of the male rubber shell 2 into the female rubber shell 1.

[0027] Please see Figure 2 , Figure 3 , Figure 5 and Figure 6The male housing 2 has multiple insertion holes 23 evenly distributed on one side corresponding to the male end limiting block 3. A male terminal 5 is inserted into each insertion hole 23. The cross-section of the insertion hole 23 is specially designed according to the size of the male terminal 5. The male end limiting block 3 has a plug that inserts into the insertion hole 23 on the male housing 2, located below the male terminal 5. The male terminal 5 has V-side 1 52, V-side 2 53, and a fitting plug 54 arranged sequentially from the outside in. The openings of V-side 1 52 and V-side 2 53 face upwards, and the V-angle of V-side 1 52 is larger than that of V-side 2 53. A snap-fit ​​block 1 51 is located below the fitting plug 54. A snap-fit ​​groove 22 for snap-fitting the snap-fit ​​block 1 51 is provided on the male housing 2 at a corresponding position. After the plug on the male end limiting block 3 is inserted into the insertion hole 23 on the male housing 2, the male terminal 5 can be stably snapped onto the male housing 2.

[0028] Please see Figure 2 , Figure 3 , Figure 4 and Figure 7 The female housing 1 has multiple insertion holes 11 evenly distributed on one side corresponding to the female end limiting block 4. A female terminal 6 is inserted into each insertion hole 11. The female end limiting block 4 has a plug that inserts into the insertion hole 11 on the female housing 1, and the plug is located on the upper side of the female terminal 6. The female terminal 6 has V-side three 61, V-side four 62 and plug-in piece 63 arranged sequentially from the outside to the inside. The openings of V-side three 61 and V-side four 62 face downwards, and the V-angle of V-side three 61 is larger than that of V-side four 62. A snap-fit ​​block 64 is arranged above the plug-in piece 63, and the snap-fit ​​block 64 and snap-fit ​​block 51 face opposite directions. The plug-in piece 63 is inserted into the fitting piece 54, and a snap-fit ​​groove 13 is provided on the female housing 1 at a corresponding position for snap-fit ​​block 64 to snap into. After the check card on the female end limit block 4 is inserted into the insertion hole 11 on the female rubber shell 1, the female terminal 6 can be stably connected to the female rubber shell 1.

[0029] In this example, the inner sides of the fitting 54 are provided with inward protrusions 55, which make rolling contact with the connector 63. By adding protrusions 55 to the fitting 54, the protrusions 55 can increase the contact friction between the connector 63 and the fitting 54, thereby further improving the connection stability between the fitting 54 and the connector 63.

[0030] Working principle: In this type of anti-misinsertion electronic connector structure, when in use, the male shell 2 is inserted into the female shell 1, and the corresponding male terminal 5 is snapped into the female terminal 6. At this time, the snap-fit ​​block 51 on the male terminal 5 snaps into the corresponding snap-fit ​​groove 22 on the male shell 2, and the snap-fit ​​block 64 on the female terminal 6 snaps into the corresponding snap-fit ​​groove 13 on the female shell 1. The snap-fit ​​limiting can make the male terminal 5 and the female terminal 6 stably snap-fit. The female end limiting block 4 and the male end limiting block 3 can further limit the position of the male terminal 5 and the female terminal 6, further ensuring the connection stability of the connector. Moreover, the specific socket design can prevent misinsertion.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
