The main housing 30 has a tubular portion 31 that is fastened to the body portion of the insulating base member 2 and a latching portion 32 that extends upward from one end of the tubular portion 31. An opening 311 is defined in the wall of the tube 15 31 4 , and the tube wall of the tubular portion is respectively formed with an "L"-shaped clamping arm 312 on both sides of the opening 311. The clamping arm 312 4, the tubular portion 3 The tube opening of the crucible is provided with a positioning hole 32 having a fastening plate 321 . The two side edges of the fastening plate 321 are read and extended to the first ear piece milk and the second side ear piece 323, and the one ear piece 323 is respectively provided with one hole 3231. The upper body 40 has a substrate 4, and the two sides of the substrate are separated by a pair of - the first wing portion 42 and the second wing portion β. The first wing is provided with a bump 42 and a second The wing portion 43 is provided with a protrusion ^, and the other second wing portion 43 is provided with a notch 432. The assembly process of the connector 1 is as follows: Please refer to the first, second and fourth figures, the coaxial of the creation Connector M331789 First, one end of a coaxial cable 50 is sequentially exposed to the outer skin 54, the outer conductor 53, the insulating layer 52, and the center conductor 51, and then the center conductor 51 is inserted into the guiding portion 11 of the connecting terminal 10 and the retaining arm 12 And welding the center conductor 51 to the guiding portion 11, since the distance between the protrusion 121 on the retaining arm I2 and the guiding portion 11 is smaller than the diameter of the center conductor 51 of the coaxial cable 50, the retaining arm 12 can be The central conductor 51 of the coaxial cable 50 is pressed. Then, the connecting terminal 10 is placed in the insulating base 20, and the guiding portion 11 and the contact portion 13 of the connecting terminal 10 are respectively received in the receiving slots of the insulating base 20. 213 and the socket slot 2111; then, the insulating base 20 to which the connection terminal 10 has been assembled is inserted into the tube of the main casing 30 In the portion 31, the positioning hole 313 on the tubular portion 31 is snap-fitted with the positioning block 2121 on the insulating base 20 to fix the insulating base 20 and the main housing 30 together, and the clamping arm on the main housing 30 312 holds the insulating layer 52 of the coaxial cable 50; thereafter, the fastening portion 32 of the main casing 30 is bent rearward so that the fastening portion 32 covers the insulating base 20 while making the middle of the insulating base 20.
