DETAILED DESCRIPTION

[0034] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 , which shows the first embodiment of the present invention's power transmission direction detection charging connector. This embodiment of the power transmission direction detection charging connector 1 includes an insulating rubber core 10, a plurality of terminals 20, and a metal housing 30. The plurality of terminals 20 are bonded to the insulating rubber core 10, which provides a structure for securing the terminals 20. The metal housing 30 is bonded to the insulating rubber core 10 and covers a portion of the insulating rubber core 10 and all of the terminals 20. In addition to reinforcing the structure of the insulating rubber core 10, the metal housing 30 also provides space for the terminals 20 to mate with a mating electrical connector and provides electromagnetic shielding for the terminals 20.

[0035] Each terminal 20 has a mating portion 20a, a retaining portion 20b, and a welding portion 20c. The mating portion 20a and the welding portion 20c are connected at both ends of the retaining portion 20b. The retaining portion 20b is coupled to the insulating rubber core 10. The mating portion 20a is exposed from the insulating rubber core 10 and can be mated with a pair of terminals of a hand-held electrical connector. The welding portion 20c is exposed from the insulating rubber core 10 and can be used to weld to the wires of a cable. In this embodiment, the retaining portion 20b is bent in a direction perpendicular to the terminal 20, so that the mating portion 20a and the welding portion 20c are located at different horizontal positions. In this embodiment, the mating portion 20a is in the shape of an elastic arm, and the welding portion 20c is in the shape of a rectangular metal plate with a large length and width to facilitate welding to the wires of the cable. Each welding portion 20c has a through hole 20d to facilitate the flow of solder. After the solder solidifies, it forms a locking structure with the welding portion 20c to increase the welding strength.

[0036] The plurality of terminals 20 include at least one ground terminal 21, at least one power terminal 22, and at least one detection terminal 23. The power transmission direction detection type charging electrical connector of this embodiment is a receptacle electrical connector for a USB Type-C device. Therefore, the plurality of terminals 20 are arranged in a first row A and a second row B, which are parallel to each other. The plurality of terminals 20 in the first row A include two first ground terminals 21A, two first power terminals 22A, and a first detection terminal 23A. The plurality of terminals 20 in the second row B include two second ground terminals 21B, two second power terminals 22B, and a second detection terminal 23B. The plurality of terminals 20 in the first row A and the plurality of terminals 20 in the second row B correspond to the pinouts of the USB Type-C device.

[0037] Therefore, the mating portion 20a of the first detection terminal 23A is positioned adjacent to the mating portion 20a of one of the two first power terminals 21B, while the mating portion 20a of the second detection terminal 23B is positioned adjacent to the mating portion 20a of one of the two second power terminals 22B. When the plurality of terminals 20 in the first row A and the plurality of terminals 20 in the second row B are arranged parallel to each other, the two first ground terminals 21A are aligned with the two second ground terminals 21B, and the two first power terminals 22A are aligned with the two second power terminals 22B. The mating portions 20a of the first detection terminal 23A and the mating portions 20a of the second detection terminal 23B are offset. As previously described, because the retaining portion 20b of the terminal 20 is bent in the vertical direction, the soldering portions 20c of the two first ground terminals 21A and the soldering portions 20c of the two second ground terminals 21B are aligned and abutted against each other, and the soldering portions 20c of the two first power terminals 22A and the soldering portions 20c of the two second power terminals 22B are aligned and abutted against each other. The retaining portions 20 b of the first detecting terminal 23A and the second detecting terminal 23B are also bent in the horizontal direction, so that the welding portions 20 c of the first detecting terminal 23A and the second detecting terminal 23B are aligned with and abut against each other.

[0038] The detection pins CC1 and CC2 of the USB type C are used to detect the direction of signal transmission. Therefore, the first detection terminal 23A and the second detection terminal 23B of the present invention are used to detect the direction of power transmission.

[0039] like Figure 2 As shown, the plurality of terminals 20 in the first row A and the plurality of terminals 20 in the second row B are formed by stamping a metal strip, and then Figure 3 As shown, the first insulating portion 11 of the insulating core 10 is formed by insert molding of the multiple terminals 20 in the first row A and the multiple terminals 20 in the second row B. The first insulating portion 11 covers the retaining portion 20b of the terminal 20, the lower portion of the mating portion 20a, and the upper portion of the welding portion 20c. The first insulating portion 11 is provided with a combination protrusion 111 and a combination hole 112 at a position corresponding to the mating portion 20a. Figure 4 、 Figure 5 and Figure 6 As shown, the combined protrusions 111 and the combined holes 112 of the first insulating portions 11 of the multiple terminals 20 in the first row A are assembled with the combined holes 112 and the combined protrusions 111 of the first insulating portions 11 of the multiple terminals 20 in the second row B. The power transmission direction detection type charging electrical connector 1 of this embodiment also includes a metal intermediate partition 40, which is disposed between the multiple terminals 20 in the first row A and the multiple terminals 20 in the second row B and is sandwiched between the first insulating portions 11 of the multiple terminals 20 in the first row A and the first insulating portions 11 of the multiple terminals 20 in the second row B.

[0040] like Figure 6 As shown, the soldering portions 20c of the plurality of terminals 20 in the first row A and the soldering portions 20c of the plurality of terminals 20 in the second row B are aligned and abutted against each other, with the ten soldering portions 20c forming a total of five soldering points. The through-holes 20d of the soldering portions 20c of the terminals 20 in the first row A and the through-holes 20d of the soldering portions 20c of the terminals 20 in the second row B are aligned with each other. The two outermost soldering portions 20c correspond to the first ground terminal 21A and the second ground terminal 21B, the central soldering portion 20c corresponds to the first detection terminal 23A and the second detection terminal 23B, and the soldering portion 20c between the outermost soldering portion 20c and the central soldering portion 20c corresponds to the first power terminal 22A and the second power terminal 22B.

[0041] Then as Figure 7 As shown, the assembled structure of the terminals 20 in the first row A, multiple terminals 20 in the second row B, and the metal intermediate plate 40 is formed into the second insulating portion 12 of the insulating rubber core 10 using an insert molding process or an overmolding process. The second insulating portion 12 covers the first insulating portion 11 and the metal intermediate plate 40 to form a tongue body 10a and a base body 10b. The mating portion 20a of the terminal 20 is located on the tongue body 10a, and the welding portion 20c of the terminal 20 is located on the base body 10b. The upper surface of the mating portion 20a of the terminal 20 is exposed from the tongue body 10a to facilitate mating with the terminal of the opposing electrical connector. The second insulating portion 12 is formed with a plurality of receiving grooves 10c at locations corresponding to the soldering portions 20c of the terminals 20. The soldering portions 20c of the terminals 20 are located within the receiving grooves 10c. The receiving grooves 10c can also accommodate cables, which are then welded to the soldering portions 20c and positioned within the receiving grooves 10c. The second insulating portion 12 is provided with a locking protrusion 10d on opposite sides of the soldering portion 20c near the terminals 20. A metal intermediate spacer 40 is located within the tongue body 10a to increase the structural strength of the tongue body 10a.

[0042] See also Figure 8 and Figure 9 , please also refer to Figure 1The metal shell 30 is connected to the insulating rubber core 10 with multiple rivet structures 33 on its upper and lower surfaces. The metal shell 30 is connected to the base body 10b of the insulating rubber core 10 and surrounds the tongue body 10a. The metal shell 30 forms a pair of interfaces 31 at one end of the tongue body 10a of the insulating rubber core 10 for docking with a counterpart electrical connector. The accommodating groove 10c and the locking protrusion 10d are exposed on the metal shell 30. The locking protrusion 10d can be used to connect the power transmission direction detection type charging electrical connector of this embodiment with the corresponding structure of the electronic device, thereby positioning the power transmission direction detection type charging electrical connector of this embodiment on the electronic device. The metal shell 30 has ribs 32 on the inner surface corresponding to the tongue body 10a of the insulating rubber core 10 to increase the stability of insertion and removal. The welding portion 20c of the first ground terminal 21A and the second ground terminal 21B is exposed and contacts the metal shell 30.

[0043] See also Figure 10 , which represents the second embodiment of the present invention's power transmission direction-detecting charging connector. This embodiment shares some structural features with the first embodiment, so identical components are given the same reference numerals and their descriptions are omitted. This embodiment differs from the first embodiment in that there is no metal separator between the multiple terminals 20 in the first row A and the multiple terminals 20 in the second row B. Instead, the first insulating portions 11 of the terminals 20 in the first row A and the first insulating portions 11 of the terminals 20 in the second row B abut against each other.

[0044] See also Figure 11 and Figure 12 , which represents the third embodiment of the power transmission direction detection charging connector of the present invention.

This embodiment differs from the first embodiment in that the retaining portion 20b of the first detection terminal 23A and the retaining portion 20b of the second detection terminal 23B are not horizontally bent. Therefore, the welding portion 20c of the first detection terminal 23A and the welding portion 20c of the second detection terminal 23B are offset. As a result, the ten welding portions 20c of the terminal 20 in this embodiment form a total of six welding points.

[0045] See also Figure 13 , which shows the state of the power transmission direction detection type charging electrical connector 1 of the present invention being combined with the electronic device E1.

This embodiment has some of the same structures as the first embodiment, so the same elements are given the same symbols and their descriptions are omitted. The difference between this embodiment and the first embodiment is that this embodiment also includes an insulating covering 60 and a waterproof seal 70. The insulating covering 60 is formed by an insert molding process or an over molding process to cover the metal shell 30, the base body 10b of the insulating rubber core 10, and the connection between the cable and the welding part 20c. The insulating covering 60 forms a flange 61 corresponding to the metal shell 30. The flange 61 surrounds the outer surface of the metal shell 30, and the waterproof seal 70 is sleeved on the flange 61. The power transmission direction detection type charging electrical connector of this embodiment is locked in the electronic device E3 by bolts M passing through the through holes 62 of the insulating covering 60.
