The two power terminals 22 of each terminal row A or B are connected in parallel via a connecting structure 24 , and the two ground terminals 23 of each terminal row A or B are connected in parallel via a jumper structure 25 .

[0027] Figures 3 to 9 The manufacturing process of the power transmission type electrical connector of the present invention with the corresponding positive and negative power terminals connected in parallel is shown. Figure 3 , Figure 4 and Figure 5 A metal strip S is formed into a Figure 3In the structure shown, the middle terminal 20 is a detection terminal 21, the terminals 20 on both sides of the detection terminal 21 are power terminals 22, and the two outermost terminals 20 are ground terminals 23. According to the pin configuration of the USB type C, the detection terminal 21 is closer to the right power terminal 22. One side of the metal strip S forms a docking portion 20a of the terminal 20, and the docking portions 20a of all the terminals 20 are arranged in a row. The other side of the metal strip S forms a welding portion 20c of the terminal, and each welding portion 20c forms a through hole H to facilitate connection with the wire of the cable. The welding portion 20c of the power terminal 22 is located at one side edge of the metal strip S, and the welding portion 20c of the grounding terminal 23 is closer to the inside of the metal strip S than the welding portion 20c of the power terminal 22, that is, the welding portion 20c of the power terminal 22 is located behind the welding portion 20c of the grounding terminal 23 and the welding portion 20c of the power terminal 22 is flush with the edges of the left and right sides of the welding portion 20c of the grounding terminal 23. The welding portion 20c of the detection terminal 21 is surrounded by the welding portion 20c of the power terminal 22 and the connecting structure 24 formed by the metal strip S connecting the welding portions 20c of the two power terminals 22.

[0028] The soldering portion 20c of the detection terminal 21 is bridged with the soldering portion 20c of the ground terminal 23 via the bridge portion 20d, and the soldering portion 20c of the power terminal 22 is bridged with the soldering portion 20c of the ground terminal 23 via the bridge portion 20e. The holding portion 20b of the left ground terminal 23 has a lateral extending crossover portion 20f, and the holding portion 20b of the right ground terminal 23 has an upwardly bent engaging portion 20g.

[0029] Then as Figure 4 As shown, the metal strip S is formed into a first insulating structure 11 on the metal strip S through an insert injection molding process, and the retaining portion 20b of each terminal 20 is combined with the first insulating structure 11. Figure 5 As shown, the bridging portion 20f is bent to the right to cross the first insulating structure 11, and cross the holding portion 20b of the power terminal 22 and the detection terminal 21, and then the clamping portion 20g is bent and clamped on the bridging portion 20f, so that the grounding terminals 23 on the left and right sides are connected in parallel. The bridging portion 20f and the clamping portion 20g form the above-mentioned bridging structure 25. Then the bridge portion 20d and the bridge portion 20e are removed. The welding portion 20c of the power terminal 22 is connected by the above-mentioned connecting structure 24 formed on one side of the metal strip S, so that the power terminals 22 on the left and right sides of the detection terminal 21 are also connected in parallel.

At this time, the metal intermediate separator 30 corresponds to the docking portion 20a of the terminal 20, and is used to support the portion of the first insulating structure 11 corresponding to the docking portion 20a and strengthen the structural strength of this portion.

[0032] Then, if Figure 8 As shown, the combination structure corresponding to the upper side of the terminal row A, the metal intermediate partition 30 and the combination structure corresponding to the lower side of the terminal row B are insert molded or overmolded to form the second insulating structure 12. The second insulating structure 12 covers the first insulating structure 11, the holding portion 20b of the terminal and the bridging structure formed by the bridging portion 20f and the engaging portion 20g, but the docking portion 20a and the welding portion 20c of the terminal 20 are exposed from the second insulating structure 12. After the second insulating structure 12 is molded, the first insulating structure 11 and the second insulating structure 12 jointly form an insulating rubber core 10.

[0034] As mentioned above, the two grounding terminals 23 of the upper terminal row A are connected in parallel through the crossover structure 25 formed by the crossover portion 20f and the clamping portion 20g, and the two grounding terminals 23 of the lower terminal row B are connected in parallel through the crossover structure 25 formed by the crossover portion 20f and the clamping portion 20g, so that all the grounding terminals 23 of the terminal rows A and B are electrically connected. Similarly, the two power terminals 22 of the upper terminal row A are connected in parallel through the connection structure 24 formed by one side edge of the metal strip S, and the two power terminals 22 of the lower terminal row B are also connected in parallel through the connection structure 24 formed by one side edge of the metal strip S, so that all the power terminals 22 of the terminal rows A and B are electrically connected.

[0035] The metal shell 40 is installed on the base 10b of the insulating rubber core 10 and surrounds the tongue portion 10a. A docking space is formed between the metal shell 40 and the tongue portion 10a, and the metal shell 40 forms a pair of interfaces 41 on the side opposite to the base 10b for docking with the opponent electrical connector. The terminal of the opponent electrical connector is docked with the docking portion 20a of the terminal 20 to form an electrical connection.

[0036] Then, if Fig. 9 As shown, the metal reinforcement 50 is disposed on the outer surface of the metal shell 40 from above. The metal reinforcement 50 of this embodiment is formed into a U shape and is sleeved on the metal shell 40 from above. The two arms of the U shape abut against the opposite sides of the metal shell 40. The metal reinforcement 50 of this embodiment is combined with the metal shell 40 by laser welding. Finally, the metal reinforcement 50 is formed as shown in FIG. Figure 1 A power delivery type electrical connector is shown with corresponding positive and negative power terminals connected in parallel.
