The latching portion 210 is disposed corresponding to the bump 16 on the insulative housing 1. The shield housing 2 is fastened to the front end surface 10 of the insulative housing 1 by the latching portion 210 being engaged with the bump 16 . Referring to FIGS. 4 and 5, the center terminal 3 is a cylindrical shape having a columnar contact portion 30 and a first 096104022 arranged in series from the columnar contact portion 30. Form No. A0101 Page 5 of 17 1003433194-0 [0008] 1360932 On November 22, 100, the page connecting portion 31, the second connecting portion 32, and the joint portion 33 were replaced. The first and second connecting portions 31, 32 and the engaging portion 33 are also cylindrical, and the cross-sectional areas thereof are all larger than the sectional area of the contact portion 30, and the cross-sectional areas of the three are sequentially reduced. As shown in the fifth figure, the receiving hole 12 is of a two-stage type, and the step portion 122 is formed. The center terminal 3 is assembled from the front end surface 10 into the insulative housing 1 , and the first and second connecting portions 31 and 32 are interference-fitted with the receiving hole 12 , and the first connecting portion 31 is blocked by the step portion 122 to prevent the center terminal 3 from moving backward. The scooping portion 121 provided in the receiving hole 12 can enhance the interference fit. The contact portion 30 is located in the receiving cavity 101, and the engaging portion 33 extends rearwardly out of the receiving hole 12. The fixing piece 4 includes a fixing portion 40 and a pin 41 which is a door-shaped structure which is bent downward from the fixing portion 40. The fixing portion 40 has a square shape, and has a matching hole 401 in the middle, and the corresponding grooves 131 are provided on both sides. Tab 402. After the center terminal 3 is assembled into the receiving hole 12, the fixing portion 40 is placed in the limiting portion 13 (see FIG. 2), the engaging hole 401 is fitted into the engaging portion 33, and then the end of the engaging portion 33 is pressed, thereby not only engaging The portion 33 is fixed to the fitting hole 401 (i.e., the conventional riveting technique), and a part of the material of the engaging portion 33 is pushed into the notch 403 of the edge of the mating 401. The portion of the engaging portion 33 that is pushed into the notch 40 3, as shown in the second figure, prevents the center terminal 3 from rotating relative to the fixing piece 4. The tabs 402 are received in the recesses 131 of the tabs 402 on both sides of the limiting portion 13 to prevent the fixing tabs 4 from rotating relative to the insulative housing 1. The center terminal 3 of the present invention is generally made of a metal having good ductility to ensure that part of the material of the joint portion 33 can be extruded into the notch 403, and the portion of the joint portion 33 is extruded into the notch 403, the joint portion 33 There is no damage such as cracks in itself. What is more, the rear end of the engaging portion 33 is pressed and deformed more severely, and the entire surface of the engaging hole 401 of the fixing piece 4 is entirely covered, and the notch 403 is also covered. 096104022 Form No. 1010101 Page 6 of 17 1003433194-0 1360932 [0009] Correction of replacement page for 100 years.
