[0035] As shown in Figures 1 to 4, in the illustrated embodiment, the housing 10 has a plurality of slots 11 spaced apart in the height direction Z of the housing 10 and extending in the lateral direction X and vertical direction Y of the housing 10. Multiple rows of terminals 12 are fixed to the housing 10, and one end of each row of terminals 12 extends into the corresponding slot 11 to electrically contact a row of mating terminals of a mating module 2 inserted into the slot 11.

Therefore, in the illustrated embodiment, the insertion and removal of the upper mating module 2' and the lower mating module 2” are performed in a sequential order. The lower mating module 2” must be inserted into the housing 10 of the connector 1 before the upper mating module 2', and the upper mating module 2' must be withdrawn from the housing 10 of the connector 1 before the lower mating module 2”.

In addition, in the illustrated embodiment, the restraining flange 25 of the upper fitting module 2' is pressed against the restraining step portion 15 of the lower fitting module 2'', which makes it possible to withdraw the lower fitting module 2'' from the lower slot 11'' only after the upper fitting module 2' has been withdrawn from the upper slot 11'. Therefore, in the illustrated embodiment, the insertion and removal of the upper mating module 2' and the lower mating module 2” are performed in a sequential order. The lower mating module 2” must be inserted into the housing 10 of the connector 1 before the upper mating module 2', and the upper mating module 2' must be withdrawn from the housing 10 of the connector 1 before the lower mating module 2”.
