COMPOSITE CONNECTOR

A composite connector that contributes to an improvement of workability for mating connectors with each other while preventing or reducing an increase in manufacturing cost is provided. A composite connector (1) according to an aspect of the present disclosure includes a first module (2) including a first housing (22) in which a first connector (21) is exposed from a distal end thereof, and a second housing (25) rotatable about the first housing (22), the second housing (25) including a second connector (23), and a second module (3) including a third connector (31), and a third housing including a fourth connector (33), the third connector (31) being configured to be mated with and electrically connected to the first connector (21), and the fourth connector (33) being configured to be mated with and electrically connected to the second connector (23). The composite connector (1) is configured so that the second and fourth connectors (23 and 33) are mated with each other in a state in which one of a projection and a recess that is formed in the second housing (25) is mated with the other of the projection and the recess that is formed in the third housing.
