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 may be 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 connection with fig. 1 and 2, the electrical connector 10 includes an insulating holder 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 the first surface 11a and the second surface 11b are, as understood, 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 disposed opposite to each other, specifically, the first terminal row 12 and the second terminal row 13 are disposed in two rows up and down in the thickness direction of the insulating base 11, and the insulating base 11 can insulate terminals such as a detection terminal, a signal transmission terminal, and a signal reception terminal, which need to be electrically insulated, from 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 to the first surface 11a and the second surface 11b of the insulating holder 11, respectively, so that the corresponding terminals are not completely wrapped by the insulating holder 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 in one-to-one correspondence with the first power terminals 121. The first power terminal 121 and the second power terminal 131 are used for supplying current to adapt to the charging function requirement of the electrical connector 10.
The conductive sheet 14 is connected with the insulating base 11, and the conductive sheet 14 is electrically connected with the first power terminal 121 and the second power terminal 131, so that the cross-sectional area of the current flowing through the conductive sheet 14 is increased, the overall impedance is reduced, the overcurrent capacity of the electric connector 10 is improved, and the charging efficiency is improved.
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. Because 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 provide current to pass through, so as to reduce the impedance of the electrical connector 10 as a whole, improve the overcurrent capacity of the electrical connector 10, and improve 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, so that the electrical connector 10 can adapt to the requirement of high-current charging to improve the charging efficiency.
In the present embodiment, the arrangement position of the conductive sheet 14 has various embodiments. Specifically, the present invention relates to a method for manufacturing a semiconductor device. As shown in fig. 5 and 6, 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 terminal 121 and the second power terminal 131 are each 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, where the first power terminal 121 contacts the conductive sheet 14, and the first power terminal 121 contacts 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 and the second power terminal 131 are in contact, so that the conductive sheet 14 is electrically connected to both the first power terminal 121 and the second power terminal 131.
It will be appreciated that in the embodiment of the present application, the conductive sheet 14 is encapsulated with the first terminal row 12 and the second terminal row 13 by the insulating base 11, and the conductive sheet 14 is electrically insulated from the insulating base 11 except for the first power terminal 121 and the second power terminal 131, and the other terminals in the first terminal row 12 and the second terminal row 13 are separated from the conductive sheet 14. For example, as shown in fig. 4 to 6, the conductive sheet 14 is located between the first terminal row 12 and the second terminal row 13, and the first power terminal 121 and the second power terminal 131 are both in contact with the contacts. 4 other terminals are provided between the 2 first power terminals 121 of the first terminal row 12, and gaps are 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 2 second power terminals 131 of the second terminal block 13. It should be noted that the corresponding terminals in the first terminal row 12 and the second terminal row 13 may be functionally identical. Taking 4 other terminals located between the 2 first power terminals 121 as an example, the 4 terminals are a signal transmission terminal, a signal reception terminal, and 2 detection terminals, respectively, the signal transmission terminal and the signal reception terminal being located between the 2 detection terminals.
It should be noted that each terminal of the first terminal row 12 and the second terminal row 13 has a solder pin exposed from 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 that are connected, 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, 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 with the second sub-base 112, the conductive sheet 14 electrically connects the first power terminal 121 and the second power terminal 131, and the overall impedance of the electrical connector 10 is reduced due to the conductive characteristic of the conductive sheet 14, so that the overcurrent performance of the electrical connector 10 is improved to adapt to the high-current charging requirement.
The first sub-seat 111 and the second sub-seat 112 are detachably connected, for example, a snap connection is adopted between the first sub-seat 111 and the second sub-seat 112, or the first sub-seat 111 is provided with a groove, the second sub-seat 112 is provided with a protrusion, and the connection of the first sub-seat 111 and the second sub-seat 112 is realized through the cooperation 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 into one body through the third sub-base 113, so that the overall structure of the electrical connector 10 is stable, and the use effect is prevented from being affected due to loosening of the terminals in the first terminal row 12 and the second terminal row 13.
As shown in connection with fig. 5 and 6, the first terminal row 12 includes the first ground terminals 122 on both sides, and correspondingly, the second terminal row 13 includes the second ground terminals 132 on both sides. The first ground terminal 122 and the second ground terminal 132 correspond to and are used to implement the ground of the electrical connector 10. The 2 first ground terminals 122 are the 2 outermost terminals of the first terminal row 12 in the width direction of the electrical connector 10, that is, the terminals of the first terminal row 12 except for the first ground terminal 122 are all located between the 2 first ground terminals 122, with the transverse direction of the insertion direction of the electrical connector 10 being the width direction of the electrical connector 10. Accordingly, the 2 second ground terminals 132 are 2 terminals of the second terminal block 13 located at the outermost layer in the width direction of the electrical connector 10, that is, terminals of the second terminal block 13 other than the second ground terminals 132 are all located between the 2 second ground terminals 132.
A middle steel sheet 15 is provided between the first terminal row 12 and the second terminal row 13. The number of the middle steel sheets 15 is specifically two, and they are respectively located between the first ground terminal 122 and the second ground terminal 132, specifically, one middle steel sheet 15 is located between the first ground terminal 122 and the second ground terminal 132 near the left side of the electrical connector 10, and the other middle steel sheet 15 is located between the first ground terminal 122 and the second ground terminal 132 near the right side of the electrical connector 10.
The middle steel sheets 15 on the two sides can provide insertion and extraction force to improve the fitting stability of the electric connector 10. For example, in some embodiments, the outer sides of the middle steel plates 15 on both sides are respectively provided with a locking boss 151, so that when the electric connector 10 performs the opposite-plug connection, the locking boss 151 is used to make the fit between the male and female sockets of the electric connector 10 not easy to fall 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 from the second ground terminal 132. The middle steel sheet 15 is used as a grounding terminal to improve the overcurrent performance of the grounding end of the electric connector 10, further reduce the overall impedance of the electric 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, the overcurrent performance is improved, and meanwhile, the number of pins is not increased.
In other embodiments, the middle steel sheet 15 may be in contact with the second ground terminal 132, and the middle steel sheet 15 may be spaced apart from the first ground terminal 122. With this arrangement, the overall impedance of the connector can be further reduced by using the medium steel sheet 15 to charge the ground terminal, and the charging efficiency can be improved.
As shown in 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 an Insert Molding process, the molded insulating base 11 has a positioning protrusion 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 formed into the first sub-seat 111 or the second sub-seat 112 and then mounted to the first sub-seat 111 or the second sub-seat 112. Taking the connection of the middle steel sheet 15 and the first sub-seat 111 as an example, after the terminals of the first terminal row 12 are packaged and fixed by an Insert Molding process, the first sub-seat 111 is formed with a positioning protrusion 111a, and the positioning protrusion 111a is inserted into a positioning groove 152 of the middle steel sheet 15, so that the middle steel sheet 15 is stably matched with the first sub-seat 111, and thus, when the first sub-seat 111 and the second sub-seat 112 are matched, the middle steel sheet 15 is further stably clamped between the two.
Another embodiment of the present application provides a method for manufacturing an electrical connector 10, including the following steps:
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, 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 terminals 121 and the second power terminals 131 are in one-to-one correspondence.
The conductive sheet 14 is disposed, 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 above method for manufacturing the electrical connector 10, 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 is utilized to increase the cross-sectional area of the power supply, so as to reduce the overall impedance, and further improve the over-current capability of the electrical connector 10, and improve 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 terminal 121 and the second power terminal 131 are in one-to-one correspondence includes:

The first sub-mount 111 is formed by injection molding such that the conductive sheet 14 and the first terminal row 12 are connected to the first sub-mount 111 and are respectively exposed to the first sub-mount 111.
In this process, the first sub-base 111 is injection molded, so that when the first sub-base 111 and the second sub-base 112 are connected in a subsequent step, the conductive sheet 14 can be contacted with the second power terminal 131, so that the conductive sheet 14 electrically connects the first power terminal 121 and the second power terminal 131.
