Description of the Related Art
Referring to
A conventional electrical connection socket cannot be easily manufactured because the two rows of terminals 92 are integrally embedded into the plastic seat 91. More particularly, when the specification becomes smaller, the manufacturing precision needs to be very high, and cannot be easily implemented.
Furthermore, the metal housing 93 is a four-sided housing bent from a metal plate sheet to have a seam to affect the shielding effect.
Moreover, the rear shielding shell of the conventional plug is formed by way of metal pulling and extending to form front and rear shielding shells fitting with each other in the front-to-rear direction, so that the manufacturing cost is so high.
Furthermore, disposing two rows of elastically movable terminals on the insulated seat of the conventional dual-position plug with the smaller dimensional specification is not so easy. It is one of main objects of the invention to make the manufacturing process become easier.
Furthermore, the conventional socket and plug are provided with internal ground shielding sheets electrically connected together. However, the conventional socket and plug are provided with two separate ground shielding sheets, so that the assembling becomes more inconvenient and the effect of strengthening the overall structure cannot be provided.

The two rows of contacts are vertically elastically movable. The end section of the extension 43 of the first terminal 40 is bent reversely to form the contact 44 projecting beyond the connection surface 323, and the contact 44 is a cut surface of a distal end.
Each of the two terminal sets is one row of 12 first terminals 40. The contacts of the two terminal sets having the same contact interface and the connection points with the same circuit serial numbers are arranged reversely.
The docking part 32 is fitted with the jointing portion 304 of the front end of the base seat 31. The structure of the docking part 32 is almost the same as that of the first embodiment, is similarly provided with two connection plates 320 facing each other in a top-to-bottom direction and having the same height and has two side plates 327 connected to the two connection plates 320 to form a fitting frame body, so that the front end of the docking part 32 is an inserting port and the rear end is a fitting port. The opposite surfaces of the two connection plates 320 are two connection surfaces 323 facing opposite directions. A connection slot 325 is formed between the two connection surfaces 323. Each of the rear sections of the inner surfaces of the two connection plates 320 is provided with one row of separate barriers to separate the space into one row of elastic movement spaces 322 to separate the extensions 43 of the two rows of first terminals 40 of the two contact interfaces. The opposite surfaces of two rows of barriers are two connection surfaces 323. The one row of elastic movement spaces 322 are much more depressed than the connection surface 323 and have bottom surfaces separated from the metal housing 60.
Each of two sides of the rear end of the docking part 32 is provided with an engagement hole 321 engaged with the engagement block 307 of the base seat 303.
The insulation plug block 330 is fitted with the hollow chamber 313 of the base seat 303. The front end of the insulation plug block 330 is formed with a limiting surface to rest and limits against the tongue of the electrical connection socket.
The height “a” of the contact interface substrate of this embodiment is about 0.75 mm, the height “b” of the connection slot 325 is about 0.9 mm, and the overall height “c” of the docking structure 75 is about 2.4 mm.

The two contact interfaces of the docking dual-position duplex plug and socket have the same contact interface, and the circuit serial numbers of the connection points of the two contact interfaces are arranged reversely.
The adapter cable of this embodiment needs to be provided with two connection point switching integrated devices 250, so that the two USB 3.0 contact interfaces of the dual-position duplex USB 3.0 electrical connection plug 103 and the two contact interfaces of the dual-position duplex electrical connection plug 123 can be integrated and switched mutually. That is, different connection points of the male and female contact interfaces can be integrated and switched mutually.

In addition, the jointing portion 304 of the front end of the base seat is a hollow frame body, which is formed by stacking the inverse-U shaped frame body and the U-shaped frame body together so that the extensions 43 of the two rows of first terminals 40 may have the shorter elastically movable arm of force, and that the contact 44 has the larger normal force.

In addition, the pins of the two terminal sets are electrically connected to a circuit board 200. The circuit board 200 may be provided with associated electrical elements or circuit protecting electrical elements. The circuit board 200 may be electrically connected to an electronic unit. The pins of the two sets of terminals and the electronic unit form the electrical connection through the circuit board.
Furthermore, the snapping convex portion 633 of the resilient snap 632 is formed by drawing and pulling a plate surface to have a larger height greater than the thickness of the metal partition plate 630. The section of the resilient snap 632 is provided with a bent portion 635 so that a vertical step is formed between the front section and the rear end, and that the middle height of the snapping convex portion 633 is substantially disposed at the middle thickness of the metal partition plate 630.
