[0042] The following is a description of exemplary embodiments of the present application in conjunction with the accompanying drawings, including various details of the embodiments of the present application to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0043] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a communication connection; it can be a direct connection, an indirect connection through an intermediate medium, or the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0044] like Figures 1 to 5 As shown, an electrical connector comprises: a housing 1, and a first electrical connection unit 2 and a second electrical connection unit 3 arranged on the housing 1, wherein the first electrical connection unit 2 and the second electrical connection unit 3 are both sockets;

[0045] The first electrical connection unit 2 includes a first base 21 and a first electrical connection member 22, and the first electrical connection member 22 is installed on the first base 21;

[0046] The second electrical connection unit 3 includes a second base 31 and a second electrical connection member 32, and the second electrical connection member 32 is installed on the second base 31;

[0047] The first electrical connector 22 is integrally formed with a first output terminal 222 and a first connection piece 223 . The first output terminal 222 is located in the first base 21 . The first connection piece 223 extends toward the second base 31 and is electrically connected to the second electrical connector 32 .

[0048] When the electrical connector of the embodiment of the present application is in use, one of the first electrical connection unit 2 and the second electrical connection unit 3 can be used as an input socket, and the other can be used as an output socket. Both electrical connection units can also be used as input sockets, or both can be used as output sockets. The embodiment of the present application does not limit this. Here, the input socket and the output socket are described from the perspective of the usage properties of the socket when in use, and do not indicate any difference in structure between the two.

[0049] The following is a description of the relevant terms involved in the embodiments of the present application:

[0050] Input socket: A socket used to connect to a power source and charge it, also known as an input socket.

[0051] Output socket: A socket used to connect electrical equipment and supply power to it, also known as an output terminal socket.

[0052] Power input terminal: A terminal used to connect a power source, which can realize the input of power. The input socket usually needs to be equipped with a power input terminal.

[0053] Output terminal: relative to the "power input terminal", this terminal is used to output the current input by the power input terminal to the power-consuming device. Whether it is an input socket or an output socket, an output terminal is required.

[0054] Connecting sheet: It is used to electrically connect two electrical connection units. It is usually in the shape of a sheet and can also be called an interconnecting sheet, a contact sheet, an interconnecting contact sheet, etc.

[0055] like Figure 1 As shown, the first electrical connection unit 2 may further include a first cover 25 , and the second electrical connection unit 3 may further include a second cover 35 .

[0056] Regardless of the type of electrical connector, all have a power input terminal and an output terminal. In the embodiment of the present application, the power input terminal can be provided in the first electrical connection unit 2 or in the second electrical connection unit 3 . Figure 2 In the embodiment, the first electrical connection unit 2 is an input socket, and the second electrical connection unit 3 is an output socket; Figure 3 In the embodiment, the second electrical connection unit 3 is an input socket, and the first electrical connection unit 2 is an output socket. Both electrical connection units are provided with respective output terminals, for example, the first electrical connection member 22 has a first output terminal 222 , and the second electrical connection member 32 has a second output terminal 322 .

[0057] In addition to the first output terminal 222, the first electrical connector 22 may also have a first connecting piece 223. The first output terminal 222 and the first connecting piece 223 are integrally stamped and formed. That is, the first electrical connector 22 is integrally formed with the first output terminal 222 and the first connecting piece 223. The function of the first connecting piece 223 is to realize the electrical connection between the first electrical connector 22 and the second electrical connector 32. Specifically, the first connecting piece 223 extends from the first base 21 to the second base 31, and is electrically connected to the second electrical connector 32 in the area where the second base 31 is located. In the embodiment of the present application, there are multiple ways of electrical connection, such as welding, crimping or riveting.

[0058] The electrical connection structure and electrical connection method of the two electrical connection units mentioned above may include various implementations, and two examples are provided below.

[0059] Example 1: The first electrical connector 22 is integrally formed with a first output terminal 222 and a first connection piece 223 , the second electrical connector 32 is integrally formed with a power input terminal and a second output terminal 322 , and the first connection piece 223 is electrically connected to the power input terminal.

[0060] Example 2: The first electrical connector 22 is integrally formed with a power input terminal, a first output terminal 222 and a first connection piece 223 , the second electrical connector 32 includes a second output terminal 322 , and the first connection piece 223 is electrically connected to the second output terminal 322 .

[0061] No matter which of the above implementations is adopted, only one electrical connection operation is required to achieve electrical connection between the two electrical connectors, and there is only one contact point between the two electrical connectors.

[0062] In the embodiment of the present application, by setting the first electrical connector 22 in the first electrical connection unit 2 to integrate the first output terminal 222 and the first connecting piece 223, and electrically connecting the first electrical connector 22 to the second electrical connector 32 of the second electrical connection unit 3 through the first connecting piece 223, compared with the prior art of electrically connecting two electrical connectors by setting an independent connecting piece, on the one hand, it can reduce one electrical connection operation, thereby simplifying the assembly process of the electrical connector; on the other hand, it can reduce the contact points between the electrical connectors, thereby reducing the risk of poor contact, and further improving the reliability of the overall product.

[0065] In this embodiment, the first through hole 224 is matched with the portion of the second electrical connector 32 located outside the second base 31. When performing the electrical connection operation, the first through hole 224 of the first connecting piece 223 is aligned with the second electrical connector 32, and the portion of the second electrical connector 32 located outside the second base 31 is pressed into the first through hole 224 to achieve electrical connection between the two. This electrical connection method can be called riveting. This embodiment can achieve reliable electrical connection and is more convenient to operate.

[0066] In the aforementioned example 1, the portion of the second electrical connector 32 outside the second base 31 may be a power input terminal. In the aforementioned example 2, the portion of the second electrical connector 32 outside the second base 31 may be one end of the second output terminal 322 .

[0067] Of course, after the portion of the second electrical connector 32 located outside the second base 31 is pressed into the first through hole 224 , the two may be welded together using a welding process, which is not limited in the embodiment of the present application.

[0068] In the embodiment of the present application, whether it is an input socket or an output socket, the number of electrical connectors is usually multiple (including two). Taking a two-hole socket as an example, the number of electrical connectors of each two-hole socket is two; taking a three-hole socket as an example, the number of electrical connectors of each three-hole socket is three. Therefore, in addition to the first electrical connector 22, the first electrical connection unit 2 also includes other electrical connectors.

[0095] In the embodiment of the present application, the input socket and the electrical connection sheet can be integrated, and the output socket and the electrical connection sheet can also be integrated. The following describes two embodiments respectively.

[0096] Example 1

[0097] like Figures 2 to 3 As shown, the first electrical connection member 22 is an input socket, and the second electrical connection unit 3 is an output socket;

[0098] The first electrical connector 22 is integrally formed with a first power input terminal 221 , a first output terminal 222 and a first connection piece 223 , and the first power input terminal 221 is located outside the first base 21 ;

[0099] The second electrical connector 32 includes a second output terminal 322 . A first end of the second output terminal 322 extends out of the second base 31 . The first connecting piece 223 extends toward the second base 31 and is electrically connected to the first end of the second output terminal 322 .

[0100] This embodiment provides a solution for integrating the input socket with the electrical connection piece. Specifically, for the input socket, the first power input terminal 221, the first output terminal 222 and the first connection piece 223 are integrally stamped to form the first electrical connector 22. The first output terminal 222 is located inside the first base 21. The first power input terminal 221 is located outside the first base 21, so that the first power input terminal 221 can be more conveniently electrically connected to an external power source.

[0101] For the output socket, the second electrical connector 32 is the second output terminal 322. The first end of the second output terminal 322 extends out of the second base 31, so that the second output terminal 322 can be more conveniently electrically connected to the first connection piece 223.

[0102] Optionally, the first connection piece 223 is adjacent to the first power input terminal 221 , and / or the first output terminal 222 is adjacent to the first power input terminal 221 .

[0103] Among them, the first connecting piece 223 is adjacent to the first power input terminal 221, which can enable the current input from the first power input terminal 221 to be directly transmitted to the second output terminal 322 through the first connecting piece 223, thereby shortening the current transmission path from the first power input terminal 221 to the second output terminal 322 and reducing power loss.

[0104] The first output terminal 222 is adjacent to the first power input terminal 221 , so that the current input from the first power input terminal 221 can be directly transmitted to the first output terminal 222 , thereby shortening the current transmission path from the first power input terminal 221 to the first output terminal 222 and reducing power loss.

[0105] Example 2

[0106] like Figures 4 to 5 As shown, the first electrical connection unit 2 is an output socket, and the second electrical connection unit 3 is an input socket;

[0107] The first electrical connector 22 is integrally formed with a first output terminal 222 and a first connecting piece 223;

[0108] The second electrical connector 32 is integrally formed with a second output terminal ( Figure 4 The second output terminal is located in the second base 31, and the second power input terminal 321 is located outside the second base 31;

[0109] The first connection piece 223 extends toward the second base 31 to be electrically connected to the second power input terminal 321 .

[0110] This embodiment provides a solution for integrating the output socket with the electrical connection piece. Specifically, for the output socket, the first output terminal 222 and the first connection piece 223 are integrally stamped to form the first electrical connection member 22. The first output terminal 222 is located inside the first base 21, and the first connection piece 223 is located outside the first base 21.

[0111] For the input socket, the second power input terminal 321 and the second output terminal are integrally stamped to form a second electrical connector 32. The second output terminal is located inside the second base 31. The second power input terminal 321 is located outside the second base 31, which not only allows the second power input terminal 321 to be more conveniently electrically connected to an external power source, but also allows the second power input terminal 321 to be more conveniently electrically connected to the first connecting piece 223.

[0112] In this embodiment, the second power input terminal 321 and the second output terminal 322 are integrally stamped and formed, so that the current input by the second power input terminal 321 can be directly transmitted to the second output terminal 322, thereby shortening the current transmission path from the second power input terminal 321 to the second output terminal 322 and reducing power loss.

[0113] The second power input terminal 321 is electrically connected to the first connecting piece 223, so that the current input by the second power input terminal 321 can be directly transmitted to the first output terminal 222 through the first connecting piece 223, thereby shortening the current transmission path from the second power input terminal 321 to the first output terminal 222 and reducing power loss.

[0114] In summary, in the embodiments of the present application, at least one electrical connector of at least one electrical connection unit of the electrical connector can adopt an integrated electrical connection sheet structure. Compared with the prior art of electrically connecting two electrical connectors by providing independent connection sheets, this can not only simplify the assembly process of the electrical connector, but also reduce the risk of poor contact, thereby improving the reliability of the overall product.

[0115] The above specific implementations do not constitute a limitation on the protection scope of this application. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included in the protection scope of this application.
