Photoelectric composite plug and component thereof

The utility model relates to a photoelectric composite plug and a component thereof. The photoelectric composite plug comprises an insulating base and a rear cover installed on the insulating base, wherein at least one optical plug and at least one power plug pin set are arranged on the insulating base; each power plug pin set comprises a zero line plug pin, a live wire plug pin and a grounding plug pin; and on the plugging surface of the insulating base, the optical plug is arranged in a zone enclosed by the zero line plug pin, the live wire plug pin and the grounding plug pin. According to the photoelectric composite plug provided by the utility model, the scattered arrangement manner of the optical plug and the power plug pin set in the prior art is improved, the entire layout after the improvement is more compact, so that the profile size of the plug with the same specification is greatly reduced. In addition, after improvement, the consumption of raw materials during production is reduced, so as to reduc
