The metal shell is usually formed by stamping and folding a metal plate, and has a substantially square hollow shell structure. The hollow shell is open at the front and rear ends to facilitate the installation of the insulating body and the mating with the matching electrical connector. After the body, the rear end of the metal casing needs to be provided with a device that abuts the rear end of the insulating body to improve the stability of the electrical connector. The metal casing generally comprises an upper plate, a side plate perpendicular to the upper plate from both sides of the upper plate, and a lower plate opposite to the upper plate, the upper plate extending from the rear end with a curved wall surface, the folding wall and the test wall surface are mounted After entering the insulating body, it will be bent and abutted against the rear end of the insulating body. After being inserted into the insulating body, it will be folded, and the former method is called secondary bending. However, this method requires high assembly precision, and the phenomenon that the bending is difficult and the bending is easy to crack is particularly obvious when the thickness of the metal plate is large. Therefore, it is necessary to provide an improved electrical connector. [New content] The purpose of this creation is to provide an electrical connector that is double-folded and realized without folding.

[Embodiment] As shown in the first to fourth figures, the present electrical connector 100 includes an insulative housing 1, a plurality of terminals 2 housed in the insulative housing 1, and a metal housing 3 surrounding the insulative housing 1. The electrical connector 100 is typically soldered to a printed circuit board (not shown) and used in conjunction with a mating electrical connector (not shown). The β-insulating body 1 includes a base portion 11 and a tongue portion 12 extending forward from the base portion 11. The base u is provided with a retaining projection 111 on both sides to cooperate with the metal casing 3, and the rear end is recessed to form a recess 112. The upper tongue portion 12 is provided with a plurality of receiving passages 121 for receiving the terminal 2 therein, and a sowing surface 122 is provided at the front end. The stomach terminal 2 includes a contact portion 21, a connecting portion 22 that is adjacent to and perpendicular to the contact portion 21 and that is engageable in the receiving passage 121, and a welded portion 23 that is bent and extended from the end of the connecting portion 22. The connecting portion 22 is provided with a spur 221 which can be engaged in the receiving passage 12 ι of the insulative housing 1 . The metal casing 3 is stamped and bent from a metal plate, and includes an upper plate 31, side plates 32 extending from both sides of the upper plate 31 and perpendicular to the upper plate 31, and opposite to the upper plate 31 and adjacent to the side plates 32. Board 33. The upper plate 31 extends downwardly with a pair of first holding pieces 311 and a second holding piece 312. The first and second holding pieces 311 and 312 are both engaged with the matching electrical connectors. The rear end of the upper plate 31 of the metal shell 3 is provided with a bent wall surface 34 abutting against the insulating body ,. The curved wall surface 34 is provided with a pre-folded arc 341 on one side of the insulating body 1 and a pre-folded one on the other side. The arc 341 is recessed to form a step 342, and the arc length of the bottom cross section of the step 342 is about twice the arc length of the pre-folded arc 341. The junction of the side plate 32 and the lower plate 33 is provided with first and second soldering legs 32 322 which are folded outward and soldered to the circuit board. The rear end of the metal casing 3 is provided with a notch 323. The notch 323 is in a semi-closed state, and the holding protrusion U1 of the insulative housing 1 can be conveniently received therein. ‘Please refer to the third figure, the terminal 2 is assembled in the insulative housing ,, and is locked in the accommodating passage 121 of the insulative housing 1 by the spurs 221, thereby stably accommodating the terminal 2 in the insulative housing i. Then, the insulating body 111 of the insulating body i is received in the notch 323 of the rear end of the metal casing 3, and the bent wall surface 34 is bent. The folded wall surface 34 is received in the groove 丨a at the rear end of the base of the insulating body 1. At this point, the entire electrical connector 100 is assembled. 6 ♦M328704 Metal shell 3 bending wall surface 34 and one side of the insulating body 丨 contact with a pre-folded arc from the other: the surface corresponding to the pre-folding arc 342 concave forming a step 342, pre-folding arc 342 to bend The portion is thinned and easily bent, and the step 342 disperses the stress concentration when the pre-folded arc 34 is formed. Thus, the structure of the pre-folded arc 341 and the step 342 makes the secondary bending easy to realize and is not easily cracked when bent. Therefore, this creation has indeed met the requirements of the new patent, and has filed a patent application in accordance with the law.
