|Title:||ELECTRICAL CONNECTION DEVICE HAVING FITTING DETECTION FUNCTION|
Provided is an electrical connection device that makes it possible to reliably detect the state in which connectors are fitted together. An electrical connection device that comprises: first and second connectors (C1, C2) that have a first and a second housing (10, 20); and a fitting detection member (30). The first housing (10) has a detection member restraining part (14B). The second housing (20) has a restriction release operation part (26) that maintains restriction of the fitting detection member (30) until the first housing (10) has reached a fitted position and that releases said restriction when the fitted position has been reached. The first housing (10) has a fitting allowance switching part that includes a fitting prevention part (19). The fitting allowance switching part can elastically deform so as to allow the fitting prevention part (19) to be displaced from a fitting prevention position into a fitting allowance position. The fitting detection member (30) has a fitting switching operation part (38) that, when installed in the first housing (10), makes the fitting allowance switching part elastically deform such that the fitting prevention part (19) is displaced into the fitting allowance position.
