Electrical connector and electrical connector set including said electrical connector
A female electrical connector includes internal terminals, an external terminal surrounding the internal terminals, and a holding member that holds the internal terminals and the external terminal and extends in a long-side direction (X axis direction) and a short-side direction (Y axis direction). The internal terminals are arranged in the long-side direction. The external terminal includes a first contact wall portion closer than the internal terminals to a corner in the long-side direction and a second contact wall portion closer than the internal terminals to a corner in the long-side direction. The first and second contact wall portions face each other in the short-side direction. The holding member includes a first restricting portion close to the first contact wall portion to compensate for misalignment in a mated state and a second restricting portion close to the second contact wall portion to compensate for misalignment in the mated state.
