An IDC type multi-conductor cable connector and method for assembling cable thereto. The cable connector has a plurality of contact terminals mounted in respective holes in a housing having a plurality of holes. The contact terminals each has a contact part provided at one end and an IDC type connection part provided at the other end thereof. The connector has means for temporarily holding the contact terminals in a position where the connection part of each terminal is exposed. The connector can be transported or delivered from the vendor in this state. A cable is assembled by IDC assembling to each exposed connection part. After the connection of the cables has been completed, the contact terminals are inserted further into their respective holes so that the connection parts become entirely covered. Such configuration eliminates the need for a cover, a component which is necessary for ordinary IDC type connector, and enables reduction in the size of the connector and in labor costs. Such housing may be used in modular form. By combining such modular housings, it is possible to construct various type of connectors merely by changing the case used to combine the modules. Such combined connectors are easy to wire at the interior portions of the cable connector. So, high packing density multi-contact connectors are provided.
