With this configuration, the projection space 25 is defined as a space that communicates with the main body space 23 along the second direction Y by the standing wall 26c and that other portions are closed. The erected wall portion 26 c is formed so that the amount of protrusion along the third direction Z from the bottom surface portion 51 is larger than the amount of protrusion of the frame-shaped wall portion 24 . Here, the standing wall portion 26c intersects with the end portion of the frame-shaped wall portion 24 at one end in the first direction X (the end opposite to the side where the injector INJ is located). A side wall portion 53 of the base 5 also serves as a portion of the standing wall portion 26 c on the other side in the first direction X (a portion on the side where the injector INJ is positioned and corresponds to an end wall portion 26 d described later).

As shown in FIGS. 7 and 8, the erected wall portion 26c is capable of coming into contact with the projecting portion 42 accommodated in the projecting portion space portion 25 when the connector body 1 is not connected to the injector INJ. The protrusion 42 is restrained from dropping out of the protrusion space 25 along the first direction X or the second direction Y, and the protrusion 42 is held. The shape of the standing wall portion 26c will be described in more detail later.

In the connector connection structure 100 configured as described above, in the protector 2, the wiring material W is routed in the wiring space 8 of the wiring portion 21, and the connector body 1 is held in each connector holding portion 22. .

A relative displacement may occur between the side members. On the other hand, the connector connection structure 100 can absorb the relative displacement between the member on the connection target 101 side and the member on the fixed target 102 side by the floating structure. As a result, in the connector connection structure 100, when the connector 3 of the connector body 1 is connected to the connection target 101, it is possible to suppress the sliding itself of the contact between the terminal 31 and the connection target 101 due to the relative displacement. can.
