Further, at both end portions of the upper wall 7, engaging portions 15 and 15 which are engaged with the locking projections -6 - (4) 1253215 30 and 30 provided in the plug housing 22 which will be described later are provided. Figs. 7 to 9 are diagrams showing a plug connector 21 which constitutes the connector of the present invention. The plug connector 2 1 is provided with a plurality of cylindrical outer casing portions 24 (four in the illustrated example) in which the plug contacts 3 2 connected to the ends of the plurality of electric wires 3 j are individually isolated and housed. The plug housing 22 is a predetermined interval corresponding to the pitch of the pin contacts 3. Each of the tubular casings 24 is formed such that the base end portion thereof is connected to the casing main body 23, and the upper ends of the respective cylindrical casing portions 24 are connected to each other through the thin connecting wall 25, and a groove shape is formed between the respective cylindrical casing portions 24. The empty department 26. The ridge piece 9 of the base case 2 is engaged with the vacant portion 26. Further, at the tip end portion of each of the cylindrical outer casing portions 24, an opening 27 for inserting the contact portion 12 for the pin contact 3 is provided. The plug contact 32 which is press-fitted to the end of the electric wire 3 1 is formed by punching and bending a conductive metal thin plate. As shown in FIG. 9, the plug contact 32 is inserted into the contact housing portion 28 which is provided in each of the cylindrical outer casing portions 24 from the outer casing main body 23 of the plug housing 22, and is provided in the plug contact member 32. The slit 33 is locked to the engaging hole 29 provided in the upper wall portion of the cylindrical outer casing portion 24 to prevent the escape. Further, the upper wall portions of the cylindrical outer casing portions 24, 24 positioned at both ends are protruding projections that are engaged with the engaging holes 15, 15 provided at both end portions of the upper wall 7 of the base casing 2 30, 30. Figs. 10 and 11 show the state of use of the connector of the present invention constituted by the above-described base connector 1 and plug connector 21.
