Chinese Patent No. 200820041955. No. 1 discloses an electrical connector in which the metal housing is of a separate design, but the metal housing is used for holding the horizontal portion of the card and the welding portion for welding is closed. Therefore, due to insufficient elasticity, the metal casing can only be assembled from the left and right sides by means of rotation to the insulation, and the rotation of the metal casing is not coplanar with the welding legs of the conductive terminals. Easy to lead to empty welding. In view of the above deficiencies, it is necessary to provide an electrical connector to improve the deficiencies of existing electrical connectors. [New Content] [0005] The present invention provides an electrical connector, in particular, an electrical connector in which a soldering piece of a metal case and a soldering portion of a terminal have a good coplanarity. Form No. Α0101 Page 5 of 16 M407508 [0006] The present invention provides an electrical connector including an insulative housing, a plurality of terminals received in the insulating body, and a metal housing assembled to both sides of the insulative housing. The insulative housing includes a base and side walls extending perpendicularly from both sides of the base. The terminal includes an elastic contact portion 'welding portion and a holding portion that connects the elastic contact portion and the welded portion and is held by the insulating body. The metal housing includes a holding portion for forming an accommodating space together with the insulating body and a side wall of the side wall covering the insulating body, wherein the side wall includes a first side wall and a second side wall which are separately disposed, and the first side wall is bent The welding piece has a second side wall bent with a resilient arm. Compared with the prior art, the present invention has at least the following beneficial effects: by adding a resilient arm on the second side wall, the metal casing can be directly assembled to the insulating body from both sides without rotation. The coplanarity of the solder joint of the housing and the soldered portion of the terminal. V. ', Discrimination, . . . , [Embodiment] [0008] Hereinafter, a specific embodiment of the present electrical connector 100 will be described with reference to the first to fourth figures. The present invention includes an insulative housing 1 , a plurality of terminals 2 housed in the insulative housing 1 , and two metal housings 3 respectively assembled on both sides of the insulative housing 1 . Referring to the third and fourth figures, the insulative housing 1 is substantially rectangular and includes a base portion 11 and side walls 12 extending vertically upward from both side edges of the base portion 11. The base portion 11 is provided with a support surface 111 for supporting an electronic card, a bottom surface 112 opposed to the support surface 111 for connection to the circuit board, and a plurality of terminal receiving grooves 113 penetrating the support surface 111 and the bottom surface 112. The terminal accommodating grooves 11 3 are provided in two rows, and each of the terminal accommodating grooves 113 is open at one end and communicated with the outside. The first recessed portion 121 is disposed on the outer side of the side wall 12, and the bottom surface 112 of the base portion 11 corresponding to the lower edge of the first recessed portion 121 is recessed upward to form the second recessed portion 122. Form No. A0101 Page 6 of 16 [0010] A recessed portion 121 is further recessed into the interior of the base portion to form a first fixing groove 1211 and a second fixing groove 1212 penetrating the second recess portion 122. Each of the metal casings 3 includes a retaining portion 30, and a side wall 31 of the side wall 12 of the covered insulating body 1 formed by the side of the retaining portion 30. The side wall 31 includes a first side wall 3丨丨 disposed on both sides and a second side wall 312 located in the middle. The first side wall 3 U and the second side wall 312 are received in the first recessed portion 121. The holding portion 3 laps over the upper surface of the side wall 12 of the insulating body and extends further to the base n of the insulating body ,. Thus, the holding portion 30 and the side wall 12 and the supporting surface U1 of the insulating body 1 An open type electronic card accommodating space is formed (not shown). The end of the first side wall 311 is bent inwardly and accommodated in the insulating body 1: a detail piece 311 〇. The second side wall 3丨2 is bent inwardly to the fixing piece 3121 of the first fixing groove 1211 of the cover body i and the elastic arm 3122 of the second fixing groove 121 2 of the insulating body 1. The end of the elastic arm 3122 extends toward the direction away from the insulating body 1 and protrudes. The cold piece 3121 and the welded piece 311〇, the elastic arm 31 22 and the welded piece 3110 are not in common.” [0011] Referring to the third figure, the terminal 2 is substantially: '丨 type, including protruding to the electronic card housing space. The elastic contact portion 21, the welded portion 22, and the elastic contact portion 21 and the welded portion 22 are fixed to the holding portion 23 of the insulating body 1. The elastic contact portion 21 is disposed opposite to the welded portion 22, that is, the elastic contact portion 21 and the welded portion 22 The horizontal direction is staggered, and when the elastic contact portion 21 of the mating terminal 2 with the mating connector (not shown) is elastically displaced downward, the elastic contact portion 21 is prevented from coming into contact with the welded portion 22. The welded portion 22 of the terminal 2 after product assembly The elastic piece 3122 of the spot metal part 3 is not coplanar with the solder piece 3110 of the metal body 3. The form number A0101 page 7 of 16 M407508 [0012] In this creation, the metal case The body 3 is directly assembled from the two sides of the insulative housing 1 , and the latching portion 30 is overlapped with the upper surface of the side wall 12 of the insulative housing 1 . The first side wall 311 and the second sidewall 312 are received in the first side wall 12 of the insulative housing 1 . The recessed portion 121 and the fixing piece 3121 are fixed to the insulating body 1 A fixing slot 1211, the elastic arm 3122 is fixed to the second fixing slot 1212 of the insulative housing 1, and the soldering piece 3110 is received in the second recess 122 of the insulative housing 1. The electrical connector 100 directly assembles metal from both sides of the insulative housing 1. The casing 3 improves the coplanarity of the welded piece 3110 of the metal casing 3 and the welded portion 22 of the terminal 2, thereby improving the welding strength. [0013] In summary, the creation has indeed met the requirements of the new patent.提出Applying a patent application in accordance with the law. However, the above-mentioned implementation methods are not limited to the equivalent modifications or changes made by those who have the usual knowledge in the technical field of this creation, which are still in the spirit of this creation.
