Electrical connector and manufacturing method thereof

Abstract

The invention discloses an electric connector and a manufacturing method thereof. The electric connector comprises an insulated body, wherein a plurality of first conductive terminals and a plurality of second conductive terminals are embedded and formed in the insulated body, a first ground terminal of each first conductive terminal comprises a first fixing portion with a first width, the first conductive terminal on the outmost side is provided with a first bridge connection portion, a second differential signal terminal pair of each second conductive terminal has a second width, the second conductive terminal on the outmost side is provided with a second bridge connection portion, the first bridge connection portion and the second bridge connection portion are used for being connected with the same bridge, the first widths are larger than the second widths, the first ground terminals can prevent signal interference among the first conductive terminals and also can prevent the second differential signal terminal pairs from generating signal interference among the first conductive terminals, and accordingly the high-frequency performance of the whole electric connector is improved.

Description

technical field [0001] The invention relates to an electrical connector and a manufacturing method thereof, in particular to an electrical connector suitable for high-speed transmission and a manufacturing method thereof. Background technique [0002] For example, a USB3.0 electrical connector disclosed in Chinese patent CN201120177087.1, the electrical connector includes a shielding shell 10, an insulating body 20, a first terminal group 30 and a second terminal group 40, wherein the first terminal group 30 and the second terminal group 40 are embedded and molded in the insulating body 20, the aforementioned shielding shell 10 is covered outside the insulating body 20, the first terminal group 30 and the second terminal group 40 are formed by the same metal strip 50, the two terminals The terminals of the group are arranged alternately and side by side; the first terminal group 30 includes a plurality of first terminals 31, and each first terminal 31 includes a first weldin...

AI Technical Summary

Problems solved by technology

[0003] However, this design is on the same strip, because the first terminal group 30 and the second terminal group 40 are arranged side by side, considering the material distribution, as shown in the attached drawing of the patent specification Figure 4 As shown, the width of the first connection portion 412 of the ground terminal in the middle of the second terminal group 40 is smaller than the width between the opposite outer sides of the two connection portions 312 of the differential signal terminal pair in the middle of the first terminal group 30, so designed, the The ground terminal in the middle of the second terminal group 40 cannot avoid signal interference from the differential signal terminal pair in the middle of the first terminal group 30 to the two differential signal terminal pairs in the second terminal group 40, and cannot meet the high frequency requirements.

[0004] In order to solve the above problems, there is an existing method of stamping and forming a first terminal group on a first metal plate, stamping and forming a second terminal group on a second metal plate, and then stacking the two groups of terminals into a top and bottom Two rows are embedded and molded in the insulating body, so that the width of the first connection part of the ground terminal in the middle of the second terminal group can be designed arbitrarily, and it is not affected by the defects of material distribution on the same strip, but the aforementioned two groups of terminals There are two metal plates that are stamped and formed separately, which requires two sets of molds, and the forming process is more complicated, and its material cost and production cost are also higher
