The object of the present invention is to provide a general purpose connector with which development costs can be reduced and inventory can be easily controlled even when a plurality of terminal arrangements are required. In order to achieve this object, a general purpose connector according to the present invention includes: a connector housing-having a base including a terminal mounting portion; at least a pair of walls formed on the base; and a plurality of partitions being inserted into the connector housing, thereby forming a receiving space with the connector housing for receiving a mating connector, the receiving space being suitable for the terminal arrangement of the mating connector, wherein mis-insertion prevention groups are formed on the partitions to prevent either incorrect insertion as a result of receiving the wrong mating connector having the same terminal arrangement or reversed insertion as a result of receiving a corresponding mating connector in a reversed orientation.
