Referring to fig. 1, the present application provides an electrical connector 10, where the electrical connector 10 may be disposed in an electronic device such as a mobile phone, a computer, or a smart watch, and is used as a charging interface. Of course, in some embodiments, the electrical connector 10 may also serve as a data interface in these electronic devices.
Specifically, as shown in fig. 1 and 2, the electrical connector 10 includes an insulating housing 11, a first terminal row 12, a second terminal row 13, and a conductive sheet 14. The insulating base 11 has a first surface 11a and a second surface 11b opposite to each other, and understandably, the first surface 11a and the second surface 11b are surfaces of the insulating base 11 perpendicular to the thickness direction. The insulating base 11 serves as a mounting base for the first terminal row 12 and the second terminal row 13, and the first terminal row 12 and the second terminal row 13 are arranged oppositely, specifically, the first terminal row 12 and the second terminal row 13 are arranged in two rows in the thickness direction of the insulating base 11, and the insulating base 11 can insulate the terminals needing electrical insulation, such as the detection terminals, the signal transmission terminals, and the signal reception terminals, in the first terminal row 12 and the second terminal row 13.
Understandably, the first terminal row 12 and the second terminal row 13 are exposed on the first surface 11a and the second surface 11b of the insulative housing 11, respectively, so that the corresponding terminals are not completely wrapped by the insulative housing 11 to satisfy the function of the electrical connector 10.
As shown in fig. 3 to 5, the first terminal row 12 includes at least 2 first power terminals 121, and the second terminal row 13 includes second power terminals 131 corresponding to the first power terminals 121 one to one. The first power supply terminal 121 and the second power supply terminal 131 are used to pass current to accommodate the charging functional requirements of the electrical connector 10.
The conductive sheet 14 is connected to the insulating base 11, and the conductive sheet 14 is electrically connected to the first power terminal 121 and the second power terminal 131, so that the conductive sheet 14 increases the cross-sectional area of the power supply to reduce the overall impedance, thereby increasing the over-current capability of the electrical connector 10 and increasing the charging efficiency.
In some embodiments, the area of the cross section of the conductive sheet 14 is greater than or equal to 5 times the area of the cross section of the first power terminal 121, and the area of the cross section of the conductive sheet 14 is greater than or equal to 5 times the area of the cross section of the second power terminal 131. Since the conductive sheet 14 electrically connects the first power terminal 121 and the second power terminal 131 of the electrical connector 10, the conductive sheet 14 can supply current to pass through, so as to reduce the impedance of the electrical connector 10 as a whole, thereby improving the overcurrent capability of the electrical connector 10 and improving the charging efficiency. In this embodiment, the area of the cross section of the conductive sheet 14 is greater than or equal to 5 times the area of the cross section of the first power terminal 121 and the second power terminal 131, so that the overcurrent capability is greatly improved, and the electrical connector 10 can adapt to the requirement of high-current charging to improve the charging efficiency.
In the embodiments of the present application, the position where the conductive sheet 14 is provided has various embodiments. In particular. As shown in fig. 5 and 6 in combination, the conductive sheet 14 is located between the first terminal row 12 and the second terminal row 13. As shown in fig. 7, the first power supply terminal 121 and the second power supply terminal 131 are both in contact with the conductive sheet 14.
In other embodiments, as shown in fig. 8, the conductive sheet 14 may be located on a side of the first terminal row 12 facing away from the second terminal row 13, the first power terminal 121 is in contact with the conductive sheet 14, and the first power terminal 121 is in contact with the second power terminal 131, so that the conductive sheet 14 is electrically connected to both the first power terminal 121 and the second power terminal 131.
In other embodiments, as shown in fig. 9, the conductive sheet 14 is located on a side of the second terminal row 13 facing away from the first terminal row 12, the second power terminal 131 is in contact with the conductive sheet 14, and the first power terminal 121 is in contact with the second power terminal 131, so that the conductive sheet 14 is electrically connected to both the first power terminal 121 and the second power terminal 131.
It is understood that in the present embodiment, the conductive sheet 14 is packaged with the first terminal row 12 and the second terminal row 13 through the insulating base 11, and under the electrical insulation of the insulating base 11, the conductive sheet 14 is electrically connected with the first power terminal 121 and the second power terminal 131, and other terminals in the first terminal row 12 and the second terminal row 13 are spaced apart from the conductive sheet 14. For example, as shown in fig. 4 to 6 in conjunction, the conductive sheet 14 is located between the first terminal row 12 and the second terminal row 13, and both the first power terminal 121 and the second power terminal 131 are in contact with the contacts. Between the 2 first power terminals 121 of the first terminal row 12, 4 other terminals are disposed, and a gap is reserved between the 4 terminals and the conductive sheet 14 to avoid electrical contact with the conductive sheet 14. Accordingly, 4 other terminals spaced apart from the conductive sheet 14 are also provided between the 2 second power supply terminals 131 of the second terminal row 13. It should be noted that the corresponding terminals in the first terminal row 12 and the second terminal row 13 may have the same function. Taking 4 other terminals located between the 2 first power terminals 121 as an example, the 4 terminals are a signal transmitting terminal, a signal receiving terminal and 2 detecting terminals, respectively, and the signal transmitting terminal and the signal receiving terminal are located between the 2 detecting terminals.
It should be noted that each of the terminals of the first terminal row 12 and the second terminal row 13 has a soldering foot exposed out of the insulating base 11 so as to connect the electrical connector 10 with the circuit board.
In some embodiments, the insulating base 11 includes a first sub-base 111 and a second sub-base 112 connected to each other, the first terminal row 12 is disposed on the first sub-base 111, the second terminal row 13 is disposed on the second sub-base 112, and the conductive sheet 14 is disposed on the first sub-base 111 or the second sub-base 112, when the first sub-base 111 is connected to the second sub-base 112, the conductive sheet 14 electrically connects the first power terminal 121 and the second power terminal 131, and the conductive property of the conductive sheet 14 reduces the overall impedance of the electrical connector 10, so as to improve the overcurrent performance of the electrical connector 10, so as to meet the requirement of high-current charging.
The first sub-base 111 and the second sub-base 112 are detachably connected, for example, a snap connection is adopted between the first sub-base 111 and the second sub-base 112, or the first sub-base 111 is provided with a groove, the second sub-base 112 is provided with a protrusion, and the connection between the first sub-base 111 and the second sub-base 112 is realized through the matching of the groove and the protrusion.
In some embodiments, the insulating base 11 includes a third sub-base 113, and the first sub-base 111 and the second sub-base 112 are injection molded integrally through the third sub-base 113, so that the overall structure of the electrical connector 10 is stable, and the problem that the terminals in the first terminal row 12 and the second terminal row 13 are loosened to affect the use effect is avoided.
As shown in fig. 5 and 6 in conjunction, the first terminal row 12 includes first ground terminals 122 on both sides, and correspondingly, the second terminal row 13 includes second ground terminals 132 on both sides. The first ground terminal 122 and the second ground terminal 132 correspond and are used to ground the electrical connector 10. It should be noted that, taking the transverse direction of the insertion direction of the electrical connector 10 as the width direction of the electrical connector 10, the 2 first ground terminals 122 are the outermost 2 terminals of the first terminal row 12 in the width direction of the electrical connector 10, that is, all the terminals of the first terminal row 12 except the first ground terminals 122 are located between the 2 first ground terminals 122. Accordingly, the 2 second ground terminals 132 are the 2 terminals of the second terminal row 13 located at the outermost layer in the width direction of the electrical connector 10, that is, the terminals of the second terminal row 13 other than the second ground terminals 132 are all located between the 2 second ground terminals 132.
A middle steel sheet 15 is disposed between the first terminal row 12 and the second terminal row 13. The number of the middle steel sheets 15 is two, and the two middle steel sheets 15 are respectively and correspondingly located between the first ground terminal 122 and the second ground terminal 132, specifically, one of the middle steel sheets 15 is located between the first ground terminal 122 and the second ground terminal 132 of the electrical connector 10 near the left side, and the other middle steel sheet 15 is located between the first ground terminal 122 and the second ground terminal 132 of the electrical connector 10 near the right side.
The middle steel sheets 15 on both sides can provide the insertion and extraction force to improve the fitting stability of the electrical connector 10. For example, in some embodiments, the locking bosses 151 are respectively disposed on the outer sides of the middle steel sheets 15 on both sides, so that when the electrical connector 10 is inserted, the locking bosses 151 are used to prevent the male and female connectors of the electrical connector 10 from falling off.
Further, as shown in fig. 10 and 11, the middle steel sheet 15 may be electrically connected to the first ground terminal 122, and the middle steel sheet 15 is spaced apart from the second ground terminal 132. The medium steel sheet 15 is used as a grounding terminal to improve the overcurrent performance of the grounding end of the electrical connector 10, further reduce the overall impedance of the electrical connector 10, and improve the charging efficiency. The middle steel sheet 15 is provided with the grounding pin 15a, so that when the middle steel sheet 15 is grounded, the pin of the first grounding terminal 122 connected with the middle steel sheet 15 can be omitted, and the number of the pins is not increased while the overcurrent performance is improved.
In other embodiments, the middle steel plate 15 may contact the second ground terminal 132, and the middle steel plate 15 may be spaced apart from the first ground terminal 122. With the arrangement, the overall impedance of the connector can be further reduced by using the middle steel sheet 15 to charge the grounding terminal, and the charging efficiency is improved.
Referring to fig. 11 and 12, the middle steel sheet 15 is provided with a positioning groove 152, so that when the middle steel sheet 15 is connected with the insulating base 11 by Insert Molding, the molded insulating base 11 has a positioning protrusion which is matched with the positioning groove 152, so that the middle steel sheet 15 is stably connected with the insulating base 11 by the matching of the positioning protrusion and the positioning groove 152.
Of course, the middle steel sheet 15 may be mounted on the first sub-base 111 or the second sub-base 112 after the first sub-base 111 or the second sub-base 112 is formed. Taking the middle steel sheet 15 connected to the first sub-base 111 as an example, after the terminals of the first terminal row 12 are encapsulated and fixed by Insert Molding, the first sub-base 111 is formed with positioning protrusions 111a, and the positioning protrusions 111a are inserted into the positioning grooves 152 of the middle steel sheet 15, so that the middle steel sheet 15 is stably fitted to the first sub-base 111, and thus the middle steel sheet 15 is further stably clamped between the first sub-base 111 and the second sub-base 112 when they are fitted.
Another embodiment of the present application provides a method for manufacturing an electrical connector 10, comprising the steps of:
a first terminal row 12 and a second terminal row 13 are provided, the first terminal row 12 comprising at least 2 first power terminals 121 and the second terminal row 13 comprising an equal number of second power terminals 131 as the first power terminals 121.
The first terminal row 12 and the second terminal row 13 are opposed so that the first power supply terminals 121 correspond to the second power supply terminals 131 one to one.
A conductive sheet 14 is provided, and the conductive sheet 14 is electrically connected to the first power terminal 121 and the second power terminal 131.
In the electrical connector 10 manufactured by the method for manufacturing the electrical connector 10, since the conductive sheet 14 is electrically connected to the first power terminal 121 and the second power terminal 131, the conductive sheet 14 is utilized to increase the cross-sectional area for power-on, so as to reduce the overall impedance, thereby increasing the over-current capability of the electrical connector 10 and increasing the charging efficiency.
In some embodiments, the step of opposing the first terminal row 12 and the second terminal row 13 such that the first power terminals 121 correspond one-to-one to the second power terminals 131 includes:
the first terminal row 12 is fitted to the first sub-mount 111 by injection molding.
The second terminal row 13 is fitted to the second sub-mount 112 by injection molding.
The first sub-mount 111 and the second sub-mount 112 are connected such that the first power supply terminal 121 and the second power supply terminal 131 correspond one to one.
As shown in fig. 12 and 13, in some embodiments, the step of embedding the first terminal row 12 in the first sub-mount 111 by injection molding includes:

The first sub-mount 111 is formed by injection molding such that the conductive sheets 14 and the first terminal row 12 are connected to the first sub-mount 111 and are exposed to the first sub-mount 111, respectively.
In this process, the first sub-mount 111 is injection molded to connect the conductive sheet 14 and the first terminal row 12, so that in the subsequent step, when the first sub-mount 111 is connected to the second sub-mount 112, the conductive sheet 14 can be in contact with the second power terminal 131, and the conductive sheet 14 electrically connects the first power terminal 121 and the second power terminal 131.
In other embodiments, as shown in fig. 14, the step of embedding the second terminal row 13 in the second sub-mount 112 by injection molding includes:
the second terminal row 13 is opposed to the conductive sheet 14, and the second power supply terminal 131 is brought into contact with the conductive sheet 14.
The second sub-mount 112 is formed by injection molding, so that the conductive sheet 14 and the second terminal row 13 are connected to the second sub-mount 112 and are exposed to the second sub-mount 112, respectively.
In the process, the second sub-mount 112 is injection molded to connect the conductive sheet 14 and the second terminal row 13, so that in the subsequent step, when the first sub-mount 111 and the second sub-mount 112 are connected, the conductive sheet 14 can be contacted with the first power terminal 121, and the conductive sheet 14 can electrically connect the first power terminal 121 and the second power terminal 131.
