New description: [New technical field] [0001] The present invention relates to an electrical connector. [Pre-Technology] [0002] Taiwan Patent No. I 322542 discloses a card connector comprising an insulative housing having a plurality of terminal receiving slots, and a conductive terminal electrically contacting the electronic card, the conductive terminals being received in corresponding terminals of the insulative housing In the receiving channel, the conductive terminal has a positioning portion, an elastic portion and a soldering portion, and the soldering portion of the conductive terminal is soldered to the circuit board by surface soldering technology. When welding, bubbles are easily generated in the solder, which affects the stability and reliability of the welding. [New Content] [0003] The purpose of this creation is to provide an electrical connector that has better soldering quality. [0004] In order to achieve the foregoing object, the technical solution of the present invention is an electrical connector, comprising an insulative housing having a mounting surface; and a conductive terminal received in the insulative housing, the soldering portion including the soldering portion abutting the mounting surface; The insulating body is provided with a vent hole that penetrates the mounting surface and is aligned with the welded portion. [0005] Compared with the prior art, the electrical connector of the present invention has the following effects: the arrangement of the venting holes can greatly reduce the bubbles generated in the solder, thereby improving the welding quality. [Embodiment] As shown in the first figure, the electrical connector 100 of the present invention includes an insulative housing 1, a conductive terminal 2 housed in the insulating body, and a shield case 3 assembled on the insulative housing. Insulating body 1 and conductive terminal 2 are integrally injection molded. Form No. A0101 Page 3 / Total 12 pages [0007] M406827 Please refer to the first to second figures, the insulating body is generally "concave, shape, insulative body" There is a base portion 11 and a pair of side walls 12 extending upward from opposite edges of the base portion. The base portion is provided with two sets of terminal receiving holes 13 extending in the direction of parallel side walls. The base portion π has opposite abutting faces (ie, upper surface) 118 and a mounting surface (ie, a lower surface) 119, the mounting surface is provided with a plurality of square recessed portions 111. The side wall 12 is provided with two symmetrical concave portions 121, and each of the recessed portions is provided with two horizontally arranged buckles. The portion 12 2 includes a horizontal holding portion 2, which is injection molded in the insulating body, a resilient contact portion 22 protruding from the abutting surface 118, and a welded portion 23 protruding from the mounting surface 119. The holding portion 21 has Two parallel long solid portions 211 and short arm portions 212. The long arm portions of the two sets of terminals are located in the middle portion u, and the short arm portions are located on the other two sides of the opposite side walls (ie, the front and rear sides, and the electronic card is inserted from the front side The short arm A groove 213 is recessed on a side of the long arm portion 211, and can be used to receive the free end of the contact portion when the contact portion is folded down. The elastic arm 22 is called the front side and the rear side of the long arm. The direction extending 'welding portion 23' extends from the short arm portion 212 to the # buckle, which also extends from the front-rear direction. The two sides of the welded portion 23 are symmetrically provided with a slit 231 which is semi-circular. Referring to the second to fourth figures, the welded portion 23 protrudes from the base mounting surface 119 and is in close contact with the recessed portion (1) of the mounting surface 119. The insulative housing is further provided through the abutting surface 118 and the mounting surface 119. The venting hole 112, the venting hole just does not affect the quality of the welding due to the bubble generated by the welding. Form No. A0101 Page 4 of 12 M406827 [0010] Please refer to the first to third As shown in the figure, the shielding shell 3 includes a main body portion 31 and a fixing portion 32 extending vertically downwards on both sides. The fixing portions are symmetrically provided with horizontally arranged snap holes 321 , and the insulating body 1 and the shielding shell 3 The assembly is achieved by the engagement of the latching portion 122 and the latching hole 321 . The end of the fixing portion 32 is further provided. The folded soldering leg 322 is used to solder the entire electrical connector 100 to the printed circuit board. [0011] When soldering, the solder can flow into the slot 231 of the soldering portion 23 and cover the splicing portion 23, The welding force of the product is increased, and at the same time, due to the setting of the grooving, the accumulation of the solder can be greatly reduced, so that the entire electrical connector is not lifted, the generation of the empty welding is avoided, and the stability and reliability of the welding are ensured.
