The connector is composed of an insulating body 2, a conductive terminal 3 and a cover body. . Wherein, the shielding shell is formed on the rim body 2, and is formed by integrally bending a metal sheet into a hollow frame, which comprises a left side wall u, a right side wall 12, an upper wall η and Next wall 14. The front end of the shielding case is a pair of sockets for docking with the socket connector. The inside is for accommodating the housing body 2 and the conductive terminal 3 (not labeled). The existing standard specifications are on the upper wall 13 There is a pair of left-negative concave holes in the middle, and the structure of the upper wall 13 is also a standardized concave hole. The design of the original design is to design the lower wall 14_ hole into a (10) portion 141, the depression The portion 141 is recessed in a non-penetrating manner at the time of manufacture, and a boss H2 structure is formed which is connected to the lower edge of the recess portion 141 so that the shield case 1 forms a closed when it is mated with the connector. The housing is configured to block the electromagnetic wave external stimuli during signal transmission; the recessed portion 141 has a considerable depth to maintain the function of the locking buckle of the elastic gusset on the original connection H, and the insulating body 2 The surface of the abutting portion 22 corresponds to each other. Therefore, the surface of the abutting portion 22 also has a matching structure, which will be described later in detail. The insulative housing 2 has a base 21 which is substantially rectangular and has a rectangular shape. The front end surface 211 extends forward along the lower edge The thin plate-shaped abutting portion 22 is specifically a paste towel, and the adapter portion 22 is plate-shaped, but the abutting portion 22 is not restricted by the tongue plate. In other embodiments, the product specification may be Other structures; a plurality of terminal slots 212 corresponding to the plurality of conductive terminals 3 are disposed on the contact end faces of the tongue plates, and the terminal slots 212 extend forwardly to the front end of the upper surface of the splicing portion 22, and simultaneously with the mating portion 22 The upper surface is continuous, which is the standard structure of the existing USB plug connector; however, on the other surface of the mating portion 22, that is, the lower surface 22, a pair of left and right symmetry is provided to communicate with the front end surface of the butt 22 Rectangular recesses 222, the widths and recessed depths of the recesses are not less than the width and height of the bosses 142 under which the shield housings are pressed, and the recesses 222 extend from the front end faces of the mating portions 22. The length should be set according to the longitudinal position of the boss 142 of the shielding case 1. The conductive terminal 3 is formed by stamping a thin metal plate, which is inserted from the rear end of the base 2 by the terminal groove 212 and then disposed at the abutting portion of the insulating body 2. 22 above table The upper part is in compliance with the USB2.0 specification for contact transmission with a USB socket connector (not shown). Please also refer to the figures 3 and 4, when the mounting portion 22 of the insulative housing 2 is reduced. The wall 14 has a _ _ _ affixing means that there is no other component extending into the middle between the two, and it is not necessary to completely face-to-face after the 'insertion of the shielding shell 1 and positioned, in the shielding shell A pair of bosses 142 on the lower wall 14 of the body 1 are slid into the recess 222 through a pair of recesses on the abutting portion 22, and the rear end surface of the boss 142 can also be designed to be abutted. Holding on the inner surface 223 of the recessed table 222, the looseness of the insulative housing 2 in the shielding case 1 can be further prevented. Please refer to the second and fifth illustrations. For another embodiment, we know that the connection is made in the USB bus. The device has a pair of emptying holes @15, that is, the abutting portion 22 having the conductive terminal 3 installed and exposed as in the present invention - the surface and the space on the shielding housing 1 i 13 are the docking space 15, which - The space is used for contacting the mating portion 411 on the socket connector and the contact portion 411 is Η direct contact with the upper wall. Considering the mating of the connector, if the recess 131 of the upper wall 13 is also changed to a boss, the docking on the socket connector will be blocked. Ρ 411 is inserted into it. Therefore, the upper wall 13 _ hole 131 of the product shown in the drawing of this creation can also be closed by the convex wire of the wire f?; however, there is a point we can Certainly, if the plug connection is connected to the socket in a completely paired manner, we can still slant (4) the upper recess 131 of the upper wall 13 of the plug connector, and this will have to be with the upper wall. 13 is also provided with a recess 412 (as shown in FIG. 5) on the mating portion 411 of the socket connector insulative housing 41 which is attached to the mating connector to fit the boss provided in the recess 131 in the plug connector. A design can be fully requested, if I/. The connector has a high-frequency nucleus request for bribery. We can also make the upper and lower walls into recesses to make the buckle action without making through holes (if the test performance is better), it can also provide complete The closing effect. Therefore, in the embodiment of the present invention, we can design a boss 142 only in the recessed portion 141 of the lower wall 14 and provide the recess 142 on the lower surface of the abutting portion 22 of the insulative housing 2. Referring to FIGS. 6 to 9 again, in another embodiment of the present invention, it is known that, on such a connector 100, the lower surface of the base 21 is recessed with a step 213 connected to the rear end surface. The step 213 is provided for reducing the height of the entire connector soldered above the PCB board, and a pair of positioning posts 214 are further disposed on the step 213 to increase the stability of the connector 1 〇 0; in order to prevent leakage of electromagnetic waves here, A metal baffle 143 is covered on the step 213. Please refer to FIGS. 6 and 7 for the first embodiment of the present embodiment. In the present embodiment, the baffle 143 for covering is directly bent back from the rear edge of the lower wall 14 of the shielding case 1. It has a wall 144 and a bending wall 145 which is descending from the bending wall 145 and is stepped with the lower wall 14 of the shielding casing after installation. The height is equivalent to the height of the step 213 of the insulative housing 2, which can still be used to reduce the height of the connector after assembly. The retaining wall M391783 • 144 is further provided with a pair of recesses 146 that cooperate with the positioning post 214. Referring to Figures 8 and 9, in the second embodiment of the present embodiment, in the present embodiment, the baffle M3 for covering is designed separately from the shielding case 1, which is subsequently mounted on The step 213 of the insulative housing 2 also has a retaining wall 144 and a bent wall 145. The retaining wall 144 is substantially in the form of a descending step, and a pair of positioning posts are disposed in the middle of the retaining wall 144. The through hole 148 of the 214 has a pair of fastening walls 147 extending downwardly on both sides, and the fastening wall 147 is fastened to the card point on both sides of the step 213 of the insulating body 2; The 145 button can be extended to the lower wall 14 遮蔽 of the shielding case 1 to press it against the looseness of the entire baffle 143. The focus of this creation is: - to completely cover the recessed portion (4) of the casing 以 to provide the boss 142 by means of stamping (10), and to be in contact with the insulating body 2. Moreover, the surface of the abutting portion which is in contact with the convex opening 142 is provided with a recess for matching. This not only reduces the interference of electromagnetic waves, but also resists the insulation of the wire and the body; second, the addition-touch (4) The step 213 of the connector is closed to further reduce electromagnetic wave interference. In order to familiarize the person with the truth and understand the spirit of the implementation of the purpose and effect of the implementation of the example and the drawings are only to explain the creation of this creation, and do not add any _ to this creation, this creation may have other Change the implementation method, so anyone who is familiar with the technology will not be divorced from the spirit of the case to carry out other styles and should be regarded as the equivalent implementation of the scope of patent application in this case.
