  • Publication number: 20240235118
    Abstract: A connector mating structure includes a male connector and a female connector mated with each other. The female connector includes a mating securing member. In a state where the male connector and the female connector of the connector mating structure are in a mating state and the mating securing member is positioned in a mating securing position, a forward end of a female locking section is positioned between an upper locking protrusion and a protrusion of an upper locking section. In this manner, assembling instability between a male housing, a female housing and the mating securing member in a forward-rearward direction is suppressed. Furthermore, a short circuit spring is in elastic contact with a short circuit release section and thus presses the female housing upward. In this manner, assembling instability between the male housing, the female housing and the mating securing member in an upward-downward direction is suppressed.
