DETAILED DESCRIPTION

[0027] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , which shows an embodiment of the composite interface type male end electrical connector of the present invention. The composite interface type male end electrical connector 1 of this embodiment includes a plurality of terminals 10, an insulating structure 20 and a metal housing 30.

[0028] A plurality of terminals 10 are arranged into a first terminal row A and a second terminal row B that are arranged in parallel and opposite to each other. Each terminal has a docking portion 10a, a fixing portion 10b, and a welding portion 10c. The docking portion 10a and the welding portion 10c are connected to opposite ends of the fixing portion 10b. The docking portion 10a of this embodiment forms a curved elastic arm structure, and the elastic deformation of the docking portion 10a can generate an elastic force that abuts against the terminal of the opposing female electrical connector. The fixing portion 10b is combined with the insulating structure 20 through an embedded injection molding process to achieve the effect of maintaining positioning. The welding portion 10c is welded to the solder pad C1 of the circuit board C to form an electrical connection with the circuit board C.

[0029] Please also refer to Figure 5The first terminal array A includes a pair of first normal signal terminals 11A, two first functional terminals 12A disposed on either side of the first normal signal terminal 11A, two first power terminals 13A disposed on either side of the two first functional terminals 12A, two first high-frequency signal terminal pairs 14A disposed on either side of the two first power terminals 13A, and two first ground terminals 15A disposed on either side of the two first high-frequency signal terminal pairs 14A. The second terminal array B includes a pair of second normal signal terminals 11B, two second functional terminals 12B disposed on either side of the second normal signal terminal 11B, two second power terminals 13B disposed on either side of the two second functional terminals 12B, two second high-frequency signal terminal pairs 14B disposed on either side of the two second power terminals 13B, and two second ground terminals 15B disposed on either side of the two second high-frequency signal terminal pairs 14B. In this embodiment, the first terminal array A and the second terminal array B are configured according to the USB Type-C specification, but the configuration of the terminal 10 of the present invention is not limited thereto. In other embodiments, the first terminal array A and the second terminal array B may also be configured according to the HDMI specification or the DisplayPort specification.

[0030] Please also see Figure 13 and Figure 14 The composite interface male end electrical connector 1 of this embodiment further includes a plurality of intermediate partitions 40. The intermediate partitions 40 are separated from each other and have a predetermined spacing, so that the intermediate partitions 40 are electrically insulated from each other. The intermediate partitions 40 are disposed between the first terminal row A and the second terminal row B. The intermediate partitions 40 include a central intermediate partition 41, two inner intermediate partitions 42 disposed on either side of the central intermediate partition 41, and two outer intermediate partitions 43 disposed outside the inner intermediate partition 42. The central intermediate partition 41 is disposed between the first conventional signal terminal pair 11A and the second conventional signal terminal pair 11B. Each inner intermediate partition 42 is disposed between the first functional terminal 12A and the second functional terminal 12B and between the first power terminal 13A and the second power terminal 13B. Each outer intermediate partition 42 is disposed between the first high-frequency signal terminal pair 14A and the second high-frequency signal terminal pair 14B and between the first ground terminal 15A and the second ground terminal 15B. The middle partition 40 of the present embodiment is located between the fixed portion 10b and the welding portion 10c of the terminal 10 of the first terminal row A and the fixed portion 10b and the welding portion 10c of the terminal 10 of the second terminal row B. No middle partition is provided between the mating portion 10a of the terminal 10 of the first terminal row A and the mating portion 10a of the terminal 10 of the second terminal row B because the tongue portion of the counterpart electrical connector is to be inserted therein.

[0031] The plurality of intermediate partitions 40 can provide electromagnetic shielding for the first terminal array A and the second terminal array B, particularly preventing crosstalk caused by electromagnetic radiation effects between the first high-frequency signal terminal pair 14A of the first terminal array A and the second high-frequency signal terminal pair 14B of the second terminal array B when transmitting high-frequency signals. Furthermore, because the plurality of intermediate partitions 40 are spaced apart by a predetermined distance, crosstalk caused by electromagnetic coupling between the first high-frequency signal terminal pairs 14A on the left and right sides of the first terminal array A and the second high-frequency signal terminal pairs 14B on the left and right sides of the second terminal array B can be prevented from occurring through the intermediate partitions 40. The plurality of intermediate partitions 40 are positioned relatively close to the fixing portions 10b of the terminals 10 of the second terminal array B, thereby generating electromagnetic coupling with the terminals 10 of the second terminal array B and achieving an impedance matching effect.

[0032] See also Figure 6 The terminals 10 of the first terminal row A and the terminals 10 of the second terminal row B are respectively bonded to two first insulating members 21 through an insert molding process. A plurality of intermediate separators 40 are also bonded to a third insulating member 23 through an insert molding process. Each first insulating member 21 has a base portion 211 and a frame portion 212. The frame portion 212 is connected to the base portion 211. The fixing portion 10b of the terminal 10 is bonded to the base portion 211, and the mating portion 10a of the terminal 10 extends from the base portion 211 into the frame portion 212. The welding portion 10c of the terminal 10 protrudes from the other end of the base portion 211 outside the first insulating member 21. Two first recesses 213 are formed on the top of the first insulating member 21 bonded to the terminals 10 of the first terminal row A.

[0033] Each frame portion 212 includes two side brackets 2121 connected to the base portion 211 and a transverse bracket 2122 connecting the two side brackets 2121. The edges of the base portion 211 and the transverse bracket 2122 protrude beyond the side brackets 2121, forming an inwardly recessed structure relative to the base portion 211 and the transverse bracket 2122. A first notch 2121a is formed at the lower edge of each side bracket 2121, and a second notch 2122a is formed at the lower edge of the transverse bracket 2122. The sidewalls on both sides of the second notch 2122a form a stepped structure.

[0034] See also Figure 7 The two first insulating components 21 are assembled through the locking structure of the locking column and the locking hole, and the third insulating component 23 is clamped at the same time, so that the terminals 10 of the first terminal column A and the terminals 10 of the second terminal column B are arranged parallel to each other, and the middle partition plate 40 is located between the terminals 10 of the first terminal column A and the terminals 10 of the second terminal column B.

[0035] See also Figure 8and Figure 10 The two second insulating components 22 are respectively assembled to the frame portion 212 of the first insulating component 21 to form the insulating structure 20 of this embodiment. The frame portions 212 of the two first insulating components 21 and the two second insulating components 21 are assembled to form a docking space S. Each second insulating component 22 has a plurality of positioning grooves 221 for engaging and positioning the docking portion 10a of the terminal 10. After the two frame portions 212 are assembled, the two transverse brackets 2122 are assembled to form the first end portion 20a of the insulating structure 20. The second notches 2122a of the transverse brackets 2122 are assembled to form a docking interface 20A. Through the stepped structure of the second notches 2122a, the docking interface 20A includes a first docking opening 20A1 and a second docking opening 20A2 that are overlapped. The first docking opening 20A1 and the second docking opening 20A2 have different length-to-width ratios and are respectively used for the tongue portion of different female electrical connectors. The two side brackets 2121 of the two first insulating members 21 are assembled to form the third end 20c and fourth end 20d of the insulating structure 20. Because the side brackets 2121 are recessed inward relative to the base portion 211 and the transverse bracket 2122, the assembled side brackets 2121 form an assembly recess 20e at the third end 20c and the fourth end 20d. The two first notches 2121a are combined to form a hollow portion 20f, which is located at the bottom wall of the assembly recess 20e. The base portions 211 of the two first insulating members 21 are assembled to form the second end 20b of the insulating structure 20.

[0036] See also Figure 9 The metal shell 30 is assembled to the insulating structure 20. The metal shell 30 includes a main body 31, two second recessed portions 32, two assembly clamping portions 33, and two clamping springs 34. The main body 31 includes a top wall 311, a bottom wall 312, and two oppositely disposed side walls 313. The two second recessed portions 32 are formed on the top wall 311. The second recessed portions 32 are disposed within the first recessed portion 213 of the insulating structure 20 and abut against the bottom wall of the first recessed portion 213. The two assembly clamping portions 33 are respectively formed on the two side walls 313. The assembly clamping portion 33 is an elastic arm structure, and the clamping spring 34 is another elastic arm structure formed in the assembly clamping portion 33, that is, an elastic arm structure in the elastic arm, and the elastic arms of the assembly clamping portion 33 and the clamping spring 34 extend in opposite directions. The two second recesses 32 abut against the assembly clamping portion 33 of the insulating structure 20 abut against the bottom wall of the assembly recess 20 e of the clamping spring 34 of the insulating structure 20 , while the clamping spring 34 passes through the hollow portion 20 f and enters the docking space S.

[0037] See also Figure 11 and Figure 12The second recessed portion 32 is relatively close to the fixing portion 10b of the first high-frequency signal terminal pair 14A of the first terminal array A. The second recessed portion 32 can generate electromagnetic coupling with the first high-frequency signal terminal pair 14A to achieve an impedance matching effect.

[0038] The composite interface male electrical connector provided by the present invention forms two overlapping first and second docking openings of different aspect ratios at the docking interface of the insulating structure, which can be docked with female electrical connectors with tongue portions having different structures. This solves the problem of the prior art requiring male electrical connectors with different interface sizes to be designed for female electrical connectors with different structures. In addition, by providing a second recessed portion in the metal shell and placing it close to the first high-frequency signal terminal pair, electromagnetic coupling can be formed with the first high-frequency signal terminal pair to achieve an impedance matching effect. Similarly, by placing the outer middle partition close to the second high-frequency signal terminal pair, electromagnetic coupling can be formed with the second high-frequency signal terminal pair to achieve an impedance matching effect.
