The front end of the second support portion 142 extends toward the circumference of the second support ring (4). The inner circumference of the third circle (four) is convexly formed with a second sleeve portion 15 and the second sleeve portion 151 is outwardly and outwardly convexly formed with two positioning pieces 152 which are uniformly distributed in the circumferential direction. A second welding groove 161 is formed between the first ring 121 and the second ring 131. A third weld groove 162 is formed between the second ring 131 and the second 183⁄4 132. The core portion 111, the first support portion m, the first broadcast ring (1), the first ring M364317 121, the first sleeve portion 141, the second support portion 142, and the second retaining ring 143 define a second receiving groove 171. The first body portion 141, the second support portion 142, the second retaining ring 143, the second sleeve portion 151, and the third ring 132 define a third receiving groove 172. Referring to the second and fifth figures, the first connecting terminal 30 has a first connecting portion 31 which is conical in shape. The front end of the first connecting portion 31 protrudes forward to form a conical top portion 32. The rear end of the first connecting portion 31 is convexly formed with a substantially annular first convex ring 33. A contact hole 34 is recessed in the central portion of the rear end surface of the first connecting portion 31. The side edge of the contact hole 34 protrudes rearward to form a fixing portion 341 having a convex ring. Referring to the second and third figures, the second connecting terminal 40 is received in the second receiving groove 171, and has a cylindrical second terminal connecting body 41. The front end of the second terminal connecting body 41 is connected. The second terminal abutting portion 42 is formed in a substantially annular shape, and the second terminal abutting portion 42 is sleeved outside the first supporting portion 112. A second terminal soldering portion 43 having an annular shape is connected to the rear end of the second terminal connecting body 41. The second terminal soldering portion 43 is received in the second soldering groove 161. The third connecting terminal 50 is received in the third receiving groove 172, and has a cylindrical third terminal connecting body 51. The front end of the third terminal connecting body 51 is connected with a substantially annular third terminal. The third terminal abutting portion 52 is sleeved outside the second supporting portion 142 . A third terminal soldering portion 53 having an annular shape is connected to the rear end of the third terminal connecting body 51, and the third terminal soldering portion 53 is housed in the third soldering groove 162. The ground terminal 60 has a substantially semi-cylindrical abutting portion 61, and a substantially semi-cylindrical welded portion 62 is connected to the rear end of the abutting portion 61. A step is formed between the abutting portion 61 and the welded portion 62. Referring to the second and fourth figures, the fixing body 70 has an annular support ring 71, and the support ring 71 has two positioning M364317 ports "2 which are evenly distributed in the circumferential direction. The front end of the support ring 71 is formed with an annular shape protruding from the circumference of the circumference of the support ring 71. The rear end of the second ring 71 is formed with two positioning grooves 75 corresponding to the position of the portion 72 in the circumferential direction.
