Abstract: The present disclosure discloses a receptacle housing and a receptacle. The receptacle housing has a housing body and a non-return element, wherein the housing body has a front side and a rear side in its axial direction. The housing body is formed with a mounting hole extending along an axial direction of the housing body to be arranged for accommodating a corresponding connecting terminal. The non-return element continuously extends from the housing body towards the rear side of the housing body to be axially block-fittable with the connecting terminal. By provision of the non-return element, the receptacle housing of the present disclosure may block the connecting terminal from retreating from the mounting hole on the housing body, so that a stable electrical connection between the connecting terminal and a mating terminal on a charging gun can be ensured.
