M383843 五、新型說明： 【新型所屬之技術領域】 本新型是有關於一種電連接器，特別是指一種金屬殼 體結構穩固的電連接器。 【先前技術】 電連接器通常會包覆金屬殼體以屏蔽電磁干擾，而且 藉由金屬殼體與絕緣本體共同界定供對接連接器對接的插 置槽。因此，若金屬殼體的結構不夠穩固，在對接連接器 插拔過程產生的不當作用力及扭力，容易導致金屬殼體被 撐開而毀損《此外，金屬殼體的結構也會影響電連接器整 體的體積，在電子產品追求輕薄短小的趨勢下，電連接器 的體積也需儘可能的縮小，以避免佔用多餘的空間。 現有的電連接器，例如，參閱圖！，中國專利專利號第 ZL200620002331.X號（對應台灣專利TWM293552 ;對應美 國專利US07371116)揭露一種插座型電連接器9,可供符 合eSATA訊號傳輸規範的插頭連接器及符合usb訊號傳輸 規範的插頭連接器分別插置。電連接器9的金屬殼體91是 由金屬板片一體彎折成形，並利用鳩尾凹凸配合的榫接構 造，在底壁911結合構成對接式的平面接縫912。由於接縫 912 /、疋對接在一起，谷易被對接連接器插入時的不當插入 力及扭力所撐開，雖然有些會在接縫912處打上壓痕藉 由壓痕使接縫912處的局部材料小變形，來加強接縫912 處的結合強度，但是仍不足以承受對接連接器的不當插入 扭力或疋更為嚴格的插入測試。另外，如圖2所示，電連 3 M383843 接器9在絕緣本體92的底部設有一下護板921，並於下護 板921内端形成一插孔922，插孔922與金屬殼體91接縫 912處直接朝後延伸的插片913相配合，組裝後能產生卡止 力量，並以下護板921支撐接縫912處，避免因加工瑕疵 或不當使用造成金屬殼體91在接縫912處被扯開。然而， 因下護板921為塑膠材質，對於金屬殼體91的支撐力量仍 嫌不足’而且下護板921會增加電連接器9的高度，亦無 法滿足減少體積的需求。 其他現有的電連接器，例如台灣專利公告號第43〇丨6〇 號揭露一種連接器組合結構，包括有一絕緣座體與一金屬 遮蔽外殼，其中絕緣座體底部朝前延伸成型有支撐板，遮 蔽外殼之底側遮蔽面延伸彎折成型有具扣片之延伸片，而 能搭接並扣結在左側遮蔽面預設之扣孔上而能抵抗侧向外 撐力，同時支撐板亦將撐托在底侧遮蔽面下方而能承受向 下外#力，故遮蔽外殼將能藉簡單之沖製加工與扣接而組 合成型出結構更堅強而足以承受對接連接器之插拔動作而 不撐開之結構。但是金屬板彎折成型後在侧邊重疊扣接的 構造，因為重疊的部份會增加連接器的寬度，至少增加一 個板厚。而且其實施例所揭露的扣片是由外而内扣接在扣 孔内，扣片不能突出扣孔，否則會伸入對接連接器的插接 空間内而干涉到對接連接器的插入，使得此種扣接構造的 扣接強度會受限。 又例如台灣專利公告號第565〇42號（對應中國專利 2157589.4，對應美國專利us〇6764339 )揭露的一種屏 4M383843 V. New description: [New technical field] The present invention relates to an electrical connector, and more particularly to an electrical connector with a stable metal casing structure. [Prior Art] The electrical connector usually covers the metal casing to shield electromagnetic interference, and the metal casing and the insulative body together define an insertion slot for the butt connector to be docked. Therefore, if the structure of the metal casing is not sufficiently stable, the improper force and the torsion force generated during the plugging and unplugging process of the mating connector may easily cause the metal casing to be expanded and damaged. In addition, the structure of the metal casing may also affect the electrical connector. The overall volume, in the pursuit of light and thin electronic products, the size of the electrical connector should also be reduced as much as possible to avoid taking up extra space. Existing electrical connectors, for example, see the figure! , Chinese Patent No. ZL200620002331.X (corresponding to Taiwan Patent TWM293552; corresponding to US Patent No. 07731116) discloses a socket type electrical connector 9 for a plug connector conforming to the eSATA signal transmission specification and a plug connection conforming to the usb signal transmission specification The devices are inserted separately. The metal case 91 of the electrical connector 9 is integrally formed by bending a metal plate piece, and is formed by a splicing structure in which the dovetail is fitted, and the bottom wall 911 is combined to form a butt-type planar seam 912. Since the seams 912 /, 疋 are butted together, the valley is easily opened by the improper insertion force and the torsion when the butt connector is inserted, although some will be indented at the seam 912 by the indentation to make the seam 912 The local material is slightly deformed to reinforce the bond strength at the seam 912, but is still insufficient to withstand the improper insertion torque of the mating connector or the more stringent insertion test. In addition, as shown in FIG. 2, the electrical connector 3 M383843 is provided with a lower guard 921 at the bottom of the insulative housing 92, and a receptacle 922 is formed at the inner end of the lower guard 921. The jack 922 and the metal housing 91 are formed. The insert 913 extending directly toward the rear of the seam 912 cooperates to generate a locking force after assembly, and the lower guard 921 supports the seam 912 to avoid the metal shell 91 at the seam 912 due to machining defects or improper use. The office was torn apart. However, since the lower guard 921 is made of a plastic material, the supporting force for the metal casing 91 is still insufficient, and the lower guard 921 increases the height of the electrical connector 9, and the volume reduction requirement cannot be satisfied. Other existing electrical connectors, such as the Taiwan Patent Publication No. 43〇丨6, discloses a connector assembly structure including an insulating base body and a metal shielded outer casing, wherein the bottom of the insulating base body is formed with a support plate extending forwardly. The bottom side shielding surface of the shielding shell is extended and bent to form an extending piece with a buckle piece, and can be overlapped and fastened on the predetermined buttonhole of the left side shielding surface to resist the lateral outward supporting force, and the supporting board will also be Supporting under the bottom side shielding surface can withstand the downward force #, so the shielding shell can be combined with the simple processing and fastening to form a stronger structure enough to withstand the insertion and removal of the docking connector without The structure of the opening. However, after the metal plate is bent and formed, the fastening structure is overlapped on the side, because the overlapping portion increases the width of the connector, and at least one plate thickness is increased. Moreover, the buckle disclosed in the embodiment is fastened from the outside to the buckle hole, and the buckle cannot protrude from the buckle hole, otherwise it will protrude into the docking space of the docking connector and interfere with the insertion of the docking connector, so that The fastening strength of such a fastening structure is limited. For example, a screen disclosed in Taiwan Patent Publication No. 565〇42 (corresponding to Chinese Patent 2157589.4, corresponding to US Patent US-6764339)
