TECHNICAL FIELD

[0001] The utility model relates to the technical field of wiring harness connection, specifically relates to an electric connector. BACKGROUND

[0002] Manufacturers produce male and female connectors according to uniform standards to ensure that connectors of different brands and models are compatible with each other. This standardized design not only reduces production costs, but also facilitates user selection and use. The standardized connector design greatly improves the interoperability between devices, promoting the development and application of technology. The design of male and female connectors allows them to fit tightly and achieve secure physical connection. The current male and female connectors use interference assembly of matching holes to achieve physical connection. During the inspection process, the loosening of male and female connectors cannot be determined by the naked eye, which leads to the conclusion that only when the corresponding alarm of the device occurs can it be determined which wiring harness connector is problematic. This cannot detect connector joint loosening in advance during routine inspection and needs to be improved. Therefore, we propose an electric connector. SUMMARY

The surface of the male plug structure is fixedly provided with a reflector around it. The outer circumferential surface of the female plug structure is provided with a through groove. When the male plug structure and the female plug structure fit tightly, the through groove and the reflector are staggered.

[0006] Further, the bottom of the male plug structure is provided with a blind insertion plane, and the inner cavity of the female plug structure is provided with a blind insertion flat mouth matched with the blind insertion plane.

[0007] Further, the convex ring A is inlaid cooperation with the concave ring groove A, the convex ring B is inlaid cooperation with the concave ring groove B, and the convex ring C is inlaid cooperation with the concave ring groove C.

The position of the through groove is located between the concave ring groove A and the concave ring groove B, and the through groove is close to the concave ring groove A.

[0009] Further, the distance between the convex ring B and the convex ring C, and the distance between the concave ring groove B and the concave ring groove C are both set to 5mm-8mm.

[0010] Further, the number of through grooves is two, and the two through grooves are located on the front and rear sides of the female plug structure.

[0011] The beneficial effects of the utility model are as follows: when the male plug structure and the female plug structure are plugged, the plurality of convex rings and the concave ring grooves are matched to improve the fastening of the male and female plug matching, when the male plug structure and the female plug structure are loose, the reflective sheet is exposed at the through groove, the inspection personnel can judge whether the plug is loose by observing whether the through groove is reflective through the light irradiation of the connector joint, and the loose condition of the wiring harness connector end can be quickly judged during the inspection.
