Abstract
Abstract A connector comprises a connector housing (E) including a plurality of terminal housing compartments (1) in each of which terminal metal pieces (G) are disposed and a terminal hooking device (F) which is detachably attached to the connector housing (E) from the rear part of the connector housing (E) in two steps of a preliminary connection state and a complete connection state. The connector housing (E) has flexible hook pieces (3) which are formed in the terminal housing compartments (1) and are engaged with and hooked to the terminal metal pieces (G) when the terminal metal pieces (G) are inserted into the terminal housing compartments (1). The terminal hooking device (F) has a plurality of flexible holding pieces (2) which extend in a direction in which the terminal hooking device (F) is inserted into and detached from the terminal housing compartments (1). In the preliminary connection state, the flexible holding piece (2) climbs onto a pushing projection (6) formed in the terminal housing compartment (1) and thereby is positioned out of a line along which the terminal metal piece (G) is inserted and drawn. In this state, the terminal metal piece (G) is freely insertable and removable. When the complete connection state is reached, the flexible holding piece (2) is guided to a gliding slope (7) formed in the terminal housing compartment (1) and is projected at a position where the flexible holding piece (2) is connected to the terminal metal piece (G).
