Each terminal 5 includes an inverted U-shaped structure 53, two elastic arms 54 disposed on the inverted U-shaped structure M339801 53, and a welded portion 51 connected below the inverted-type structure 53. In the present embodiment, the terminal 5 is The sheet is integrally stamped and bent. The inverted U-shaped structure 53 includes a first limiting wall 57 that is upright and spaced apart from each other, a first limiting wall 58 , and a top wall 59 connected between the first limiting wall 57 and the second limiting wall 58 . . The first limiting wall 57 includes a first base portion 571 and two first connecting portions 572 extending from the sides of the first base portion 571 to the upper side in a flat strip shape. The second limiting wall 58 has a second base portion 582, and two second connecting portions 582 extending in a flat strip shape from the two sides of the second base portion 581, respectively, and a barb is formed on each side of the second base portion 581.

It should be noted that, as shown in FIG. 4 and FIG. 1B, in the present embodiment, the inverted u-shaped structure 53 of the terminal 5 and the elastic arm 54 are formed by longitudinally punching out a plane on a strip 500. After the inverted u-shaped groove 5〇1, the longitudinal plate in the area of the inverted U-shaped groove 501 which is developed in the plane is bent forward and downward to form the inverted U-shaped structure 53 and the elastic arm 54. The area of the material used for the belt is mostly distributed in the longitudinal direction. Therefore, compared with the conventional figure 1 or FIG. 3, the belt 5 of the present invention is between every two terminals 5. The gap can be reduced, in addition to the full use of the tape · 10 M339801 material, so that the number of terminals 5 that can be formed by the unit length of the strip 500 is increased. The distance between the two is reduced. When the terminals 5 of the tape are installed in the insulative housing 4, each terminal 5 on the tape $(9) can only correspond to each of the insulative bodies 4__ The terminal accommodating portion*, in other words, the terminal accommodating portion 4 of the insulating body 400 can be installed by using the end + 5 on the _ tape, without having to be divided into secondary installations, thereby not only saving the material cost of the tape 'The time during which the terminal 5 is assembled to the insulative body 400 can also be saved.
另外，在本新型的端子5中，由於二彈性臂M界定出 的插入區543是位在倒u型結構„頂壁59的二第三連接 段591之間’ CPU或其他晶片模組的針腳是先通過二第三 連接段591之間的插入口 再進入二彈性臂54之間的插 入區543及接觸區544,因此，該二第三連接段591亦具有 可導引CPU針腳插入端+ 5以及保護二彈性f 54的作用。In addition, in the terminal 5 of the present invention, the insertion area 543 defined by the two elastic arms M is located between the two third connection sections 591 of the inverted u-shaped structure „top wall 59 ′'s pins of the CPU or other chip modules. The insertion area 543 and the contact area 544 between the two elastic arms 54 are re-entered through the insertion port between the two third connection sections 591. Therefore, the second connection sections 591 also have a CPU pin insertion end + 5 and protect the role of the two elastic f 54.
