The metal casing 7 is formed by pressing a metal material. First, the metal shell 7 is sleeved on the shielding shell 6 to form a semi-finished product. The positioning portion 74 of the metal case 7 is received in the groove 342 and is held forward against the rear end portion 34, and a pair of rear end portions 34 of the shielding case 6 prevent the main body mold together. Group 200 moves backward. A plurality of convex portions 75 located on the upper plate portion 71 and the lower plate portion 72 of the metal case 7 are allowed to clamp the shielding case 6. The convex portions 75 of the metal casing 7 are not allowed to contact each of the waterproof films 8. A plurality of convex portions 75 located on the upper plate portion 71 or a plurality of convex portions 75 located on the lower plate portion 72 and the shielding case 6 are fixed by welding, so that the shielding case 6 and the metal shell are fixed. 7electrical connection. Then, the semi-finished product is placed vertically with the rear surface 312 facing upward. The liquid insulating material is injected into the stepped portion 32. Since the stepped portion 32 and the rear surface 312 of the base 31 are stepped, the liquid insulating material is affected by gravity along the stepped portion 32. The first stepped surface 321 flows from the top to the rear surface 312 to fill the channel 38. When the liquid insulating material is injected above the second stepped surface 33, the liquid insulating material is caused to pass through each of the through holes 341. The first inclined surface 331 and the second inclined surface 332 are further promoted to flow the liquid insulating material to fully fill the sol space 67. The rear ends of the pair of island portions 3112 are not covered by the liquid insulating material. The liquid insulating material is solidified to form a waterproof rubber plate 9. The waterproof rubber plate 9 fills the channels 38 and passes through each of the through holes 341. The waterproof rubber sheet covers the first step surface 321 and the second step surface 33 of the step portion 32. The waterproof rubber plate 9 blocks the gap between the insulating body 3 and the shielding shell 6, thereby effectively preventing liquid substances such as water from flowing into the electronic device from the riveting seam (not labeled) and the opening 631 (not shown).示) 中。 In the). In the above, the metal shell 7 is welded to the shielding shell 6 first, and then the waterproof rubber sheet 9 is injection-molded to prevent the waterproof rubber sheet 9 from being heated and melted during welding, thereby ensuring a stable waterproof effect. Finally, the metal shell 7 is used to hold the electrical connector 100 on the circuit board (not shown) through the plurality of holding feet 73, so that the metal shell 7 and the shielding shell 6 and the The circuit board (not shown) is connected to ground.
與先前技術相比，本發明具有如下有益效果：由於所述基座31設置有一臺階部32，所述第二臺階面33和各穿孔341與所述臺階部32共同促進液態絕緣材料在所述溶膠空間67內之流動，令液態絕緣材料可以更好地填充溶膠空間67且凝固後形成防水膠板9，具有更好之防水效果。由於所述遮蔽殼體6通過所述前擋部63、後擋部64、抵持部68及後端邊緣共同在向後，向下及向上方向上抵持所述本體模組200，更由於金屬外殼7通過所述定位部74向前抵持所述本體模組200，使所述遮蔽殼體6和金屬外殼7共同將所述本體模組200穩定固持於所述遮蔽殼體6內，具有更好之結構穩定性，亦保證了防水膠板9與所述遮蔽殼體6和本體模組200之間之穩定固持，保證了防水穩定性。Compared with the prior art, the present invention has the following beneficial effects: Since the base 31 is provided with a stepped portion 32, the second stepped surface 33 and each of the through holes 341 and the stepped portion 32 jointly promote a liquid insulating material in the stepped portion 32. The flow in the sol space 67 allows the liquid insulating material to better fill the sol space 67 and forms a waterproof rubber sheet 9 after solidification, which has a better waterproof effect. Because the shielding case 6 resists the body module 200 in the backward, downward, and upward directions through the front stop portion 63, the rear stop portion 64, the abutment portion 68, and the rear edge together, it is more due to the metal The housing 7 is held against the main body module 200 through the positioning portion 74, so that the shielding housing 6 and the metal housing 7 jointly hold the main body module 200 in the shielding housing 6 stably. Better structural stability also ensures stable holding between the waterproof rubber plate 9 and the shielding case 6 and the main body module 200, ensuring waterproof stability.
