Description

The present invention relates to a high definition multimedia connector, and more particularly to a high definition multimedia connector capable of producing an integrally formed structure and a method of fabricating the same.

The current electrical connector has been widely used in the field of communication, such as the technology disclosed in Chinese Patent No. 200720070543.6, the socket connector includes a plurality of signal terminals, a plurality of ground terminals, an insulating body for accommodating the signal terminals and the ground terminals, An outer casing and a positioning member for accommodating the insulative housing, wherein the positioning member is engaged with the lower surface of the insulative housing, and is provided with a first column, a second column, and a third column of plural holes, and one end of each of the ground terminals passes through the circuit The predetermined via holes in the third column of the board are in electrical contact with the circuit on the circuit board, and one end of each signal terminal passes through the preset holes in the first and second columns of the circuit board and the circuit on the circuit board. The electrical contact is formed; the three-row design of the structure has the effect of improving the crosstalk of the terminal, but the assembly of the terminal and the insulating body is assembled and inserted, resulting in low assembly efficiency, not to mention the application of the method to the smaller. The size of the structure.

In addition, the socket connector has the positioning member, and the signal terminals and the ground terminals are permeable to the positioning member, and one end of each of the ground terminals is electrically connected to the circuit board through the positioning member. Therefore, the impedance in the signal terminal and the crosstalk between adjacent signal terminals can be effectively reduced, and the differential signal can be better transmitted. Only the positioning member needs to open the mold, which increases the manufacturing cost and the manufacturing process, and the positioning member The device is fastened to the insulating body, so that the positioning of the terminal may result in poor positioning stability due to assembly tolerance of the positioning member.

In view of this, there are inventors who propose improvements, such as the number of patent certificates issued by the Republic of China. The technology disclosed in Patent No. M380638 mainly utilizes the assembly method of the upper and lower modules to simplify the process and provide better assembly effect, wherein the electrical connector of the case includes an upper module and a lower module. And a shielding shell, the upper module comprises an upper main seat, and the upper main seat comprises an upper base, a thin plate-shaped tongue plate extends forward from the center of the front end surface of the upper base, and the plurality of first terminals are embedded The molding method is disposed on the upper surface of the tongue plate at an equal interval, and a terminal groove for the plurality of second terminals is formed on the lower surface of the tongue plate corresponding to each of the first terminals of the tongue plate surface, and the lower portion is formed. The module includes a lower main seat, and the lower main seat includes a lower base, and the second terminal and the lower base are embedded and formed to extend forward from the center of the front end face of the lower base at equal intervals.

Although the above cases use the assembly method of the upper and lower modules to simplify the process and provide better assembly results, since the components have tolerance problems, the upper and lower modules are prone to loosening when assembled, and the product structure The strength is not high, and since the second terminals are only accommodated in the terminal slots of the tongue plate, there is no fixing between the tongue plates and the tongue plates, so that the second terminals are easily warped and deformed. In addition, since there is no fixed structure between the terminal portion of the first terminal and the upper main seat, the one terminal is suspended from the upper main seat, and if the terminal portion is soldered to a circuit board, the terminal is likely to be caused. The line positioning stability of the part and the circuit board is reduced; thus, it is known that there are still many areas for improvement in the prior art.
