[0026] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] like Figure 1 As shown, Figure 1 A schematic diagram of the three-dimensional structure of an electrical connector in at least one embodiment of the present application is shown. The electrical connector is used to electrically connect to the connected part 200 to achieve electrical conduction with the connected part 200. After electrical conduction, the electrical connector and the connected part 200 can be used for current transmission or signal transmission. The realization of different functions is determined based on the types of the electrical connector and the connected part 200. For example, USB (Universal Serial Bus) is a common electrical connector, which can be used for current transmission, such as for charging mobile phones, and can also be used for signal transmission, such as transferring files between mobile phones and computers.

[0028] like Figure 2 As shown, Figure 2 for Figure 1 The exploded view of the partial structure of the electrical connector is shown. Figure 1 and Figure 2The electrical connector includes an insulating body 110, a metal shielding cover 120, a metal locking pin 130 and a solder 140. The insulating body 110 is used to fix the metal terminal 150, and the metal terminal 150 is used to be electrically connected to the connected part 200. For example, the insulating body 110 can be made of plastic material. The metal shielding cover 120 is sleeved on the outside of at least a part of the insulating body 110 to make the electrical connector resistant to electromagnetic interference (EMI) or protected from electrostatic discharge (ESD). Specifically, the metal locking pin 130 is connected to the insulating body 110, and a grounding terminal 131 is provided on the metal locking pin 130. The insulating body 110, the metal shielding cover 120 and the metal locking pin 130 form an accommodating space 160 (such as Figure 1 shown).

[0029] The solder 140 is at least partially disposed in the accommodating space 160. The solder 140 is used to melt and securely connect the metal shield 120 and the metal lock pin 130 during welding so that the metal shield 120 and the metal lock pin 130 form an electrical connection. Figure 2 In the illustrated embodiment, the solder 140 is a flat block-shaped structure installed within the accommodating space 160. It should be noted that when the solder 140 is not melted, the metal shield 120 and the metal locking pin 130 are separable. At this point, the metal shield 120 and the metal locking pin 130 can be separated. In subsequent processing, a reflow process can be used to melt the solder 140 and fill the accommodating space 160 to a certain extent. Finally, the solder 140 cools and solidifies, forming an electrical connection between the metal shield 120 and the metal locking pin 130. At this point, the metal shield 120 and the metal locking pin 130 are fixedly connected and electrically connected, resolving the problem of poor contact between the overlapping shielding structure and the grounding portion of the conventional shielding structure.

[0030] like Figure 3 As shown, Figure 3 It is a structural schematic diagram of the metal shielding cover 120 in the electrical connector in one embodiment. The metal shielding cover 120 includes a cover body 121 and a connecting portion 122 connected to the cover body 121. The cover body 121 can be roughly in the shape of an elongated strip, and a connecting portion 122 is respectively provided along both ends of the elongated cover body 121. The entire metal shielding cover 120 can be formed by bending or welding a metal sheet. The cover body 121 is used to be sleeved on at least a portion of the insulating body 110. For example, the cover body 121 can completely cover the insulating body 110; for another example, the cover body 121 can cover a portion of the insulating body 110, that is, a portion of the insulating body 110 can extend out of the covering range of the cover body 121. The connecting portion 122 is used to connect the metal lock pin 130 , that is, when the solder 140 is melted, the connecting portion 122 and the metal lock pin 130 can be connected through the solder 140 . Furthermore, the connecting portion 122 and the metal lock pin 130 can be fixedly connected and electrically connected through the solder 140 .

[0031] like Figure 3 As shown, an inner cavity 123 is formed on the connecting portion 122 , and the inner cavity 123 is used for inserting at least a portion of the metal locking pin 130 .

[0032] like Figure 4 As shown, Figure 4 The figure is a schematic structural diagram of a metal locking pin 130 of an electrical connector according to one embodiment. The metal locking pin 130 includes a locking pin body 132, at least a portion of which is inserted into the inner cavity 123. The inner wall of the inner cavity 123 and the outer wall of the portion of the locking pin body 132 inserted into the inner cavity 123 together form an accommodating space 160. Specifically, the locking pin body 132 is generally elongated, with one end 132A of the elongated locking pin body 132 inserted into the inner cavity 123. An outer wall of the end 132A of the locking pin body 132 and an inner wall of the inner cavity 123 are spaced apart to form an accommodating space 160 for accommodating the solder 140. The accommodating space 160 can be flat. When the solder 140 is placed in the accommodating space 160, the two opposing surfaces of the solder 140 can respectively adhere to an outer wall of the end 132A of the locking pin body 132 and an inner wall of the inner cavity 123. When the solder 140 melts and solidifies again, the solder 140 securely connects an outer wall of one end 132A of the locking pin body 132 and an inner wall of the inner cavity 123 .

[0033] The solder 140 is confined within the accommodating space 160 by at least the metal shield 120 and the metal locking pin 130. When the electrical connector is assembled at the upstream manufacturer and the downstream manufacturer melts the solder 140 to connect the metal shield 120 and the metal locking pin 130, during the transfer of the electrical connector between the upstream and downstream manufacturers, the solder 140 is confined within the accommodating space 160 and thus does not escape from the accommodating space 160, making it less likely to be lost. Since the solder 140 is already contained within the accommodating space 160 when the electrical connector is shipped from the upstream manufacturer, the downstream manufacturer can directly perform soldering after receiving the electrical connector without having to provide new solder 140, thereby improving the work efficiency of the downstream manufacturer.

[0034] like Figure 3 As shown, the metal shield 120 includes a bent portion 124, and the connecting portion 122 is fixedly connected to the bent portion 124, or the connecting portion 122 and the bent portion 124 are integrally formed. Figure 1As shown, when the metal lock pin 130 is inserted into the inner cavity 123, the outer wall of the metal lock pin 130 and the inner wall of the inner cavity 123 form an accommodating space 160 for accommodating the brazing material 140. The bent portion 124 extends toward the lock pin body 132 and, through at least the bent portion 124, confines the brazing material 140 within the accommodating space 160. In other words, the bent portion 124 extends toward the lock pin body 132 to block at least a portion of the opening of the accommodating space 160 through the bent portion 124, thereby preventing the brazing material 140 from escaping from the accommodating space 160 through the opening.

[0035] like Figure 1 and Figure 2 As shown, the electrical connector is configured for removable electrical connection with a connected component 200. The connected component 200 is provided with a groove 210. The metal locking pin 130 includes an elastic retaining member 133 connected to a locking pin body 132. After the electrical connector and the connected component 200 are electrically connected, the elastic retaining member 133 at least partially engages the groove 210. This locks the relative position of the connected component 200 and the insulating body 110, preventing the connected component 200 from separating from the insulating body 110 and causing a poor electrical connection. To separate the connected component 200 from the insulating body 110, the elastic retaining member 133 is moved to disengage from the groove 210.

[0036] like Figure 2 As shown, the connected member 200 can be in the shape of a thin plate, and one end of the thin plate-shaped connected member 200 is electrically connected to the metal terminal 150 in the insulating body 110. Specifically, the insulating body 110 is provided with a socket, and the metal terminal 150 is provided in the socket. One end of the thin plate-shaped connecting member is inserted into the socket, and a large part of the connecting member is located outside the socket and is suspended. For this purpose, Figure 4 As shown, the metal locking pin 130 includes a supporting portion 134 connected to the locking pin body 132 . The supporting portion 134 is used to support the connected component 200 . For example, the supporting portion 134 can be supported on the bottom of the connected component 200 .

[0037] like Figure 1 As shown, in one embodiment, the electrical connector further includes a circuit board 170, the insulating body 110 is fixedly connected to the circuit board 170, and the metal terminal 150 is electrically connected to the circuit board 170. Figure 2 As shown, a grounding pad 171 is provided on the circuit board 170 , and the grounding end 131 of the metal locking pin 130 is electrically connected to the grounding pad 171 .

[0038] like Figure 2 As shown, there are at least two metal locking pins 130 , which are respectively disposed at two ends of the insulating body 110 .

[0039] The present application also provides an electronic product, comprising the electrical connector according to any one of the above embodiments, and further comprising a connected component 200, wherein the connected component 200 is detachably electrically connected to the electrical connector.
