[0100] The female end insulating rubber core 122 respectively engages and positions the first female end terminal 1211, the second female end terminal 1212, the third female end terminal 1213, the fourth female end terminal 1214, the fifth female end terminal 1215 and the sixth female end terminal 1216, so that the first female end terminal 1211, the second female end terminal 1212, the third female end terminal 1213, the fourth female end terminal 1214, the fifth female end terminal 1215 and the sixth female end terminal 1216 remain separated, and respectively extend into the first female end main internal plug-in sub-space S11, the second female end main internal plug-in sub-space S12, the third female end main internal plug-in sub-space S13, the fourth female end main internal plug-in sub-space S14, the first female end secondary internal plug-in sub-space S21 and the second female end secondary internal plug-in sub-space S22.

[0101] It should be noted that when the male end connector 11 is plugged into the female end connector 12 in the plugging direction D, the first male end main plugging guide structure G1111, the second male end main plugging guide structure G1112 and the first male end secondary plugging guide structure G1211 respectively enter the first female end main plugging guide channel G2121, the second female end main plugging guide channel G2122 and the first female end secondary plugging guide channel G2221, and the first female end main plugging guide structure G2111, the second female end main plugging guide structure G2112 and the first female end secondary plugging guide structure G2211 respectively enter the first male end main plugging guide channel G1121, the second male end main plugging guide channel G1122 and the first male end secondary plugging guide channel G1221, so as to provide guidance for the male end connector 11 in the plugging direction D. The connection to D causes the first male terminal 1111, the second male terminal 1112, the third male terminal 1113, the fourth male terminal 1114, the fifth male terminal 1115 and the sixth male terminal 1116 to respectively enter the first female end main internal plug-in sub-space S11, the second female end main internal plug-in sub-space S12, the third female end main internal plug-in sub-space S13, the fourth female end main internal plug-in sub-space S14, the first female end secondary internal plug-in sub-space S21 and the second female end secondary internal plug-in sub-space S22, and respectively plug in the first female end terminal 1211, the second female end terminal 1212, the third female end terminal 1213, the fourth female end terminal 1214, the fifth female end terminal 1215 and the sixth female end terminal 1216 to provide power or signal transmission for the electrical equipment.

[0102] At Figures 11 to 12 In the illustrated embodiment, the first female end primary plug-in guide structure G2111 has a T-shaped cross-section that can form a foolproof structure; the second female end primary plug-in guide structure G2112 has a T-shaped cross-section that can form a foolproof structure; and the first female end secondary plug-in guide structure G2211 has a T-shaped cross-section that can form a foolproof structure. In this way, these foolproof structures can provide interference when the male connector 11 is plugged in the wrong direction D, preventing the male connector 11 from plugging into the female connector 12 in the wrong direction.

[0103] In addition, Figures 11 to 12In the illustrated embodiment, the first female end rubber core transverse inner wall 1225 intersects the first female end rubber core longitudinal outer wall 1223 at a substantially perpendicular angle to form a foolproof structure; the second female end rubber core transverse inner wall 1226 intersects the first female end rubber core longitudinal inner wall 1227 at a substantially perpendicular angle to form a foolproof structure; and the third female end rubber core transverse inner wall 1229 intersects the second female end rubber core longitudinal outer wall 1224 or the third female end rubber core longitudinal outer wall 1228 at a substantially perpendicular angle to form a foolproof structure. Thus, the foolproof structure can provide interference when the male connector 11 is inserted in the incorrect insertion direction D, thereby preventing the male connector 11 from being inserted into the female connector 12 in the incorrect direction.

[0104] Furthermore, the female end insulating rubber core 122 can define a transverse extension surface A. The first female end insulating rubber core transverse inner wall 1225, the second female end insulating rubber core transverse inner wall 1226, and the second female end insulating rubber core transverse inner wall 1227 respectively extend on the transverse extension surface A to form a foolproof structure. Moreover, the first female end insulating rubber core longitudinal outer wall 1223, the first female end insulating rubber core longitudinal inner wall 1227, the second female end insulating rubber core longitudinal outer wall 1224, and the third female end insulating rubber core longitudinal outer wall 1228 respectively intersect substantially perpendicularly with the transverse extension surface A to form a foolproof structure. In this way, the foolproof structure can provide interference when the male end connector 11 is inserted in the wrong direction D, thereby preventing the male end connector 11 from being inserted into the female end connector 12 in the wrong direction.

[0105] Furthermore, Figures 11 to 12 In the illustrated embodiment, the female end insulating rubber core 122 further includes a first female end rubber core chamfer structure 12201 and a second female end rubber core chamfer structure 12202. The first female end rubber core chamfer structure 12201 connects the first female end rubber core transverse inner wall 1225 and the first female end rubber core longitudinal outer wall 1223, respectively, to form a first female end main plug-in foolproof structure F1. The second female end rubber core chamfer structure 12202 connects the first female end rubber core longitudinal inner wall 1227 and the second female end rubber core transverse inner wall 1226, respectively, to form a second female end main plug-in foolproof structure F2. It should be noted that the first female end main plug-in foolproof structure F1 and the second female end main plug-in foolproof structure F2 can provide interference when the male end connector 11 is plugged in the wrong direction D, thereby preventing the male end connector 11 from plugging into the female end connector 12 in the wrong direction.
