This embodiment is substantially the same as the first embodiment except for the difference that the electronic module 85 of this embodiment has a printed circuit board 86, on which one row of nine connection portions 87 and an electronic unit 88 are disposed. The one row of connection portions 87 are electrically connected to the electronic unit 88. The electronic unit 88 is a storage unit including a memory and associated electronic elements. The rear sections of the first pins 61 of the one row of first terminals 60 and the rear sections of the second pins 71 of the one row of second terminals 70 are in the form of horizontal pins and disposed on the same level. The first pins 61 of the one row of first terminals 60 and the second pins 71 of the one row of second terminals 70 are bonded and electrically connected to the one row of nine connection portions 87 of the electronic module 85 by way of surface mount technology (SMT).
As shown in
As shown in
The electronic module 85 has a printed circuit board having one surface formed with one row of connection portions 87, and the other surface electrically connected to an electronic unit and being packaged. The electronic module 85 is a storage module. The first pins 61 of the one row of first terminals 60 and the second pins 71 of the one row of second terminals 70 can directly elastically contact the connection portions 87 and then may be bonded. The housing 90 is a metal casing extending to the front end of the first insulating seat 40 and covering two side surfaces and a bottom surface of the first insulating seat 40. In addition, a rear cover 94 is provided to cover the rear end.
In this embodiment, the sheet-like male plug without the fitting slot is provided. If the two sides of the housing 90 project from the first surface 41, the mistake-proof structure can be formed.

This embodiment has the rear plug 100 tightly plugging into the front metal casing 91. Thus, when the integral plastic casing 95 is formed upon glue pouring, the glue cannot flow through the holes of the rear ends of the first and second insulating seats 40 and 50. In addition, the front metal casing 91 is assembled with the rear casing 910 to completely cover and shield the electrical wires of the electrical connection cable 80.
To sum up, the invention has the following advantages.
1. Each of the stacked first and second insulating seats is formed with one row of terminal slots and is assembled with one row of terminals. Each of the first and second insulating seats 40 and 50 has a joint surface arranged to separate the connection portions of the terminals thereon, so that the manufacturing processes can be simplified.
2. The pins of the two rows of terminals may be arranged in an upper row and a lower row separated from each other and may be electrically connected to the electrical connection cable. So, no electrical interference is induced.
3. The pins of the two rows of terminals can be arranged at the same level and thus can be easily electrically connected to an electronic module.
4. The one row of first connection portions 64 and the one row of second connection portions 74 satisfy the USB 3.0 specification. The one row of first terminals 60 and the one row of second terminals 70 have the arrangement structures for high-frequency signal transmission.
5. The extensions of the one row of first terminals and the elastic arms of the one row of second terminals are completely staggered without overlap in the top-viewing direction. The elastic arms of the one row of second terminals cannot touch the one row of first terminals when the elastic arms of the one row of second terminals elastically move.
7. The metal housing can completely cover and shield the electrical wires of the electrical connection cable.
8. The rear plug 100 is provided to tightly plug into the front metal casing 91.
Thus, when the integral plastic casing 95 is formed by way of glue pouring, the glue cannot flow through the holes of the rear ends of the first and second insulating seats 40 and 50.
9. The positions of the elastic arms of the one row of second terminals 70 can be directly restricted in the second insulating seat 50.
Although the electrical male plugs are described in the above-mentioned embodiments, the feature of the structure of the invention can also be applied to the female electrical connector, such as the USB 3.0 female electrical connector.
