The electrical connector 100 includes a needle-shaped inner conductor 10, an insulator 20, a tubular outer conductor 30, a metal shell 40, and an insulating outer shell 50. The inner conductor 10 is needle-shaped, L-shaped, fixed to the insulator 20, and includes a contact portion 11 and a pin 12 protruding out of the insulator 20. The metal case 40 is formed by punching a metal plate, which forms a receiving cavity 401 having a rectangular structure, and the metal case 40 includes a front plate 41 having a through hole 411. The outer conductor 30 has a tubular shape, a plurality of welding pieces 31 are bent at the rear end thereof, and the welding pieces 31 are welded to the front plate 41 of the metal shell, thereby connecting the outer conductor 30 and the metal shell 40. After the insulator 20 is assembled with the metal shell 40 and the outer conductor 30, the insulator 20 is at least partially accommodated in the accommodating cavity 401, the contact portion 11 of the inner conductor 10 is accommodated in the outer conductor 30 through the through hole 411, and the insulating shell 50 covers the outer conductor 30 and the outer side of the metal shell 40.

In the embodiment shown in fig. 6, 7 and 9, the insulator 20 includes a block 22 and a cylindrical portion 21 extending horizontally forward from the block 22, the contact portion 11 of the inner conductor passes forward through the cylindrical portion 21, and the pin 13 of the inner conductor passes downward through the bottom surface of the block 22. The cylindrical portion 21 is closely accommodated in the outer conductor 30.

The inner conductor 10 includes an L-shaped middle portion 130, and a front cylindrical portion 131 and a lower cylindrical portion 132 extending from two ends of the middle portion 130, wherein the cross section of the middle portion 130 is a rectangular structure, the front cylindrical portion 131 forms the contact portion 11, and the lower cylindrical portion 132 forms the pin 12. In a particular embodiment, a portion of the front cylindrical portion 131 adjacent the intermediate portion 130 is embedded within the insulator 20, as can be seen with reference to fig. 10. Although the two may be flush with each other. The intermediate portion 130 is provided with a projection 133 projecting rearward adjacent to the lower cylindrical portion 132, the projection being buried in the insulator 20. The middle portion 130 has a rectangular structure and a bump structure, so as to stably fix the inner conductor 10 in the insulator 20, and the insulator 20 can cover the inner conductor 10 by plastic injection molding, thereby forming an inner conductor module 10A. The front end of the block 22 is provided with a positioning portion 23 projecting forward, and the front plate 41 of the metal case is provided with a positioning hole 412 for receiving the positioning portion 23, thereby positioning the inner conductor module 10A and the metal case 40 well in the up-down, left-right directions.

The outer conductor 30 is formed by a metal plate which is rolled to form a tubular structure having a complementary dovetail groove configuration (see fig. 5), and three or four of the weld tabs 31 (see fig. 8) are provided at the rear end thereof, the weld tabs 31 having a width greater than 0.6 mm. The outer conductor 31 passes through the through hole 411 of the front plate 41 such that the soldering tab 31 thereof is soldered to the rear surface 410 of the front plate 41.

The metal shell 40 is formed by stamping and bending a metal plate, and includes the front plate 41, two side plates 42 and a top plate 43 bent backward from the front plate, and a rear plate 44 independent from the front plate, and the rear plate 44 is fixed to the side plates 42 and/or the top plate 43 by means of locking or welding. In the embodiment, the rear plate 44 extends forwards to form two side eaves 441 and a top eaves 442, the side eaves 441 has a fastening hole 443, the side plate 42 has a fastening block 421 fixed in the fastening hole 443, so as to fix the rear plate 44 to the metal casing 40, and the side eaves and the top eaves are pressed on the outer sides of the side plate and the top plate, respectively, so as to form a complete shielding frame, as shown in fig. 4 and 5. The side plates of the metal shell extend downward to form two welding feet 45. Thus, the inner and outer conductors and the metal housing form a complete conductive unit 100A.

The insulating housing 50 seals the metal shell 40 therein, and as shown in fig. 1 and 2, a butt space 501 is formed between the insulating housing 50 and the outer conductor 30, and a butt cavity (not numbered) is formed between the contact portion of the inner conductor 10 and the inner surface of the outer conductor. Meanwhile, the insulating housing 50 fills the space between the metal shell 40 and the inner conductor module 10A, and as is clear from fig. 2, only the leads 12 and the soldering leads 45 pass through the bottom surface. Meanwhile, the waterproof ring 60 is sleeved outside the insulating shell 50, so that the electric connector 100 has a good waterproof effect.
