Abstract

PURPOSE: To let a male terminal be surely mounted to a specified position, and to make the aforesaid terminal small in size by inserting the first male terminal between elastic hold pieces at a first and a second side wall. CONSTITUTION: The orthogonal connection type relay terminal T2 is mounted to a first male terminal 12 from above. Namely, the terminal 12 is held by elastic hold pieces 1b and 2b in the plate thickness direction, and concurrently the terminal is brought into a condition where a first side surface 12a abuts against a fourth side wall 4, and furthermore a second side surface 12b is in contact with an elastic presser piece 3a. Subsequently, a second male terminal 14 is mounted to the terminal T2 from above. Namely, the second male terminal 14 is inserted between the second side wall 12b and the presser piece 3a of the terminal 14, and let the male terminal 14 be held by the side wall 12b and the presser piece 3a. At this time, the terminal 12 is held in its width direction by the terminal 14 and the side wall 14, and the movement in its width direction of the terminal 14 is controlled by side walls 1 and 2. Thus as mentioned above, the insertion of the terminal 12 between the hold pieces 1b and 2b of each side wall 1 and 2 thereby allows the terminal 12 to be held, and it is held in the direction of plate thickness, and concurrently the movement of the terminal in the width direction is also controlled by the side wall 4 and the presser piece 3a.
