Insertion/extraction force reducing connector

A insertion/extraction force reducing connector, comprising:

• a first connector housing having a first terminal holding part which holds plural first terminal metal fittings, and a hood part which extends cylindrically from a front outer circumferential portion of the first terminal holding part and to which a second connector housing is connected and fitted;
• and
• the second connector housing which holds plural second terminal metal fittings to be fitted with and connected to the respective first terminal metal fittings, and in which the second terminal metal fittings are fitted with and connected to the respective first terminal metal fittings when the second connector housing is fitted into the hood part;
• wherein the second connector housing holds the second terminal metal fittings in such a manner that the second terminal metal fitting are divided into plural groups, and when the second connector housing is inserted into or pulled out of the first connector housing, sets of the second terminal metal fittings belonging to the respective groups are engaged with or pulled out of associated sets of first terminal metal fittings in order on a group-by-group basis;
• the second connector housing comprises:
• a first housing which holds second terminal metal fittings belonging to a first group and is to be fitted into the hood part;
• and
• a second housing which is positioned at a temporary lock position on one side of the first housing by a first support arm which is integrally formed with the first housing and is located on the one side of the first housing and which holds second terminal metal fittings belonging to a second group which are disposed adjacent to the second terminal metal fittings belonging to the first group on the one side of the first housing;
• and
• the second housing is connected slidably to a portion located on the one side of the first housing so that during a fitting manipulation for fitting the second connector housing into the first connector housing, fitting of the second terminal metal fittings belonging to the second group with corresponding ones of the first terminal metal fittings is completed earlier than fitting of the second terminal metal fittings belonging to the first group.
