Due to the existence of the guide column 105 and the guide groove 205, if the male end plug 1 and the female end socket 2 are plugged in incorrectly, the male end plug-in part 1031 cannot be inserted into the slot 2034 on the female end plug-in part 2031, thereby realizing the anti-foolproof and anti-misplugging functions to avoid the occurrence of wrong plugging.

[0038] like Figure 1 and Figure 3 As shown, in this embodiment, a first mounting groove 1011 is opened on the right side of the male end shielding shell 101, the male end insulating seat 102 is fixed in the first mounting groove 1011, the male end wiring harness 103 is installed on the male end insulating seat 102, and an inner step groove 1012 is opened on the right inner wall of the first mounting groove 1011. In this way, the male end shielding shell 101 protects the internal male end insulating seat 102 and the male end wiring harness 103.

[0039] like Figure 3 As shown, in this embodiment, the male end wiring harness 103 includes a male end plug-in portion 1031, a male end mounting portion 1032 and a male end connecting wire 1033 which are connected in sequence. The diameter of the male end plug-in portion 1031 is smaller than the diameter of the male end mounting portion 1032. The outer surface of the male end mounting portion 1032 is provided with a circle of first grooves. The front and rear sides of the male end insulating seat 102 are provided with first through holes 1021 that penetrate the left and right sides.

[0040] like Figure 1 and Figure 4As shown, in this embodiment, a second mounting groove 2011 is provided on the left side of the female end shielding shell 201, the female end insulating seat 202 is fixed in the second mounting groove 2011, the female end wiring harness 203 is installed on the female end insulating seat 202, and an outer step groove 2012 is provided on the left side outer surface of the second mounting groove 2011, and the outer step groove 2012 is adapted to the inner step groove 1012. In this way, the internal female end insulating seat 202 and the female end wiring harness 203 are protected by the female end shielding shell 201.

[0041] like Figure 4 and Figure 6 As shown, in this embodiment, a circle of sealing groove 2013 is provided on the outer surface of the outer step groove 2012, and a sealing ring 2014 is arranged inside the sealing groove 2013. In this way, after the male plug 1 and the female socket 2 are inserted together, the outer step groove 2012 is inserted into the inner step groove 1012, and the sealing ring 2014 on the outer step groove 2012 makes the entire electrical connector have a good sealing function and achieves better waterproof performance.

[0042] like Figure 4 As shown, in this embodiment, the female end wiring harness 203 includes a female end plug-in portion 2031, a female end mounting portion 2032 and a female end connecting wire 2033 connected in sequence, the outer surface of the female end mounting portion 2032 is provided with a circle of second grooves, the left side of the female end plug-in portion 2031 is provided with a slot 2034 corresponding to the male end plug-in portion 1031, and the outer surface of the female end plug-in portion 2031 is provided with a plurality of long holes 2035 that penetrate the slots 2034 and the outer surface of the female end plug-in portion 2031. A slot 2034 is provided on the upper surface, and a plurality of long holes 2035 are provided on the outer surface, so that the plugging and unplugging force between the male end plug-in portion 1031 and the slot 2034 is stable and reliable, and the vibration resistance is good. The front and rear sides of the female end insulating seat 202 are provided with second through holes 2021 that penetrate the left and right sides. A second convex ring that is opposite to the second groove is fixedly connected in the second through hole 2021.

[0043] like Figure 2 and Figure 8As shown, in this embodiment, the male end shielding shell 101 and the female end shielding shell 201 are internally fixedly connected with a shielding net 3, and the outer surfaces of the male end shielding shell 101 and the female end shielding shell 201 are both provided with a chlorinated polyethylene flame retardant layer 4, and the shielding net 3 can be injection molded inside the male end shielding shell 101 and the female end shielding shell 201. In this arrangement, since the male end shielding shell 101 and the female end shielding shell 201 are internally fixedly connected with the shielding net 3, the metal shielding net 3 is wrapped around the inside for multiple turns to avoid the occurrence of seams, thereby better shielding external electromagnetic signals, improving the signal shielding capability of the connector, and the chlorinated polyethylene flame retardant layer 4 can have good flame retardant properties, thereby improving the safety of the connector body.

The fulcrum 1041, the pressing portion 1042 and the clamping portion 1043 are all integrally formed with the male end shielding shell 101. In this way, when the guide column 105 is aligned with the guide groove 205, the male end plug-in portion 1031 will be inserted into the slot 2034 on the female end plug-in portion 2031. At the same time, the clamping portion 1043 will be slightly deformed and rotated around the fulcrum 1041 until the clamping portion 1043 is reset and clamped at the clamping block 204, thereby completing the automatic locking function.

[0045] The technical solution provided by the utility model is a connector with a reverse insertion identification function. When in use, the male end plug 1 and the female end socket 2 are plugged together. Due to the existence of the guide column 105 and the guide groove 205, if the male end plug 1 and the female end socket 2 are plugged in incorrectly, the male end plug part 1031 cannot be inserted into the slot 2034 on the female end plug part 2031, thereby realizing the anti-mistake and anti-misplugging functions to avoid the occurrence of wrong plugging. When the guide column 105 is aligned with the guide groove 205, the male end plug part 1031 is inserted into the slot 2034 on the female end plug part 2031, and the clamping part 1043 is rotated around the fulcrum. 1041 is slightly deformed and rotated until the snap-fitting portion 1043 is reset and snap-fitted to the snap-fitting block 204, thereby completing the automatic locking function. Since the male end shielding shell 101 and the female end shielding shell 201 are internally fixedly connected with the shielding net 3, the metal shielding net 3 is wrapped around the inside for multiple turns to avoid the occurrence of seams, thereby better shielding the external electromagnetic signal and improving the signal shielding capability of the connector. The outer surfaces of the male end shielding shell 101 and the female end shielding shell 201 are both provided with a chlorinated polyethylene flame retardant layer 4, which can have good flame retardant properties and improve the safety of the connector body.

[0046] The connector has a slot 2034 on the female end plug-in portion 2031 and a plurality of long holes 2035 on the outer surface, so that the plugging and unplugging force between the male end plug-in portion 1031 and the slot 2034 is stable and reliable, and has good vibration resistance. The male end plug 1 and the female end socket 2 are restricted by the cooperation of the buckle 104 and the block 204 to prevent the male end plug 1 and the female end socket 2 from being separated. In addition, the sealing ring 2014 on the outer step groove 2012 is used to make the entire electrical connector have a good sealing function and achieve better waterproof performance.
