[0054] Please refer to Figure 1-Figure 5 , is a schematic structural diagram of an integrated electrical connector provided in an embodiment of the present invention, wherein the integrated electrical connector includes a mounting base 100 and a connecting assembly 200.

[0055] Please refer to Figure 1 The mounting base 100 is suitable for being installed at the external connection port of the active device corresponding to the integrated electrical connector. A connector plug shell 110 is formed on the mounting base 100, and a terminal mounting cavity is provided in the connector plug shell 110.

[0056] Specifically, the active device may be a battery pack or a signal-type active device.

[0057] Specifically, the integrated electrical connector in this embodiment is a socket connector, and one end of the integrated electrical connector on the outer side of the mounting base 100 (the outer side after the mounting base 100 is mounted on the active device) is suitable for plugging with a corresponding plug connector.

[0058] Specifically, Figure 1 As shown, a snap-fitting boss 114 is provided on one end of the connector plug shell 110 on the outer side of the mounting base 100 (also referred to as the rear end in the first direction described below), and the snap-fitting boss 114 is suitable for snapping with a corresponding snap hook in the plug connector to ensure that the integrated electrical connector in this embodiment is firmly connected to the corresponding plug connector.

[0059] Please refer to Figure 2-Figure 4 The connection assembly 200 includes a terminal shell 210 and a terminal assembly 220, and the terminal assembly 220 is arranged in the terminal shell 210; a pair of elastic connecting arms 211 are fixed to the outside of the terminal shell 210; a first limiting portion 212 is arranged on the terminal shell 210, and a second limiting portion 213 is arranged on the elastic connecting arm 211, and a third limiting portion 111 and a fourth limiting portion 112 are respectively arranged on the connector plug shell 110 corresponding to the first limiting portion 212 and the second limiting portion 213.

[0060] In the integrated electrical connector of this embodiment, when the connecting component 200 is inserted into the terminal mounting cavity along the first direction, the first limiting portion 212 abuts against the third limiting portion 111 to limit the movement of the connecting component 200 in the first direction, and the second limiting portion 213 abuts against the fourth limiting portion 112 to limit the movement of the connecting component 200 in the second direction; the second direction is the opposite direction to the first direction.

[0061] In this embodiment, Figure 6 As shown, the holding force of the connection component 200 can reach more than 110N. Under the pressure of 110N, the displacement of the connection component 200 in the first direction or the second direction will be less than 0.2mm, and the connection between the connection component 200 and the connector plug shell 110 is highly stable.

[0062] Specifically, Figure 2 and Figure 3 As shown, the terminal assembly 220 includes a shielding shell 221, which is sleeved on the terminal shell 210; the specific structure of the shielding shell 221 and the specific sleeve connection method between it and the terminal shell 210 can be any one of the existing methods, or can be the sleeve connection method provided in the following content of this embodiment.

[0063] Specifically, Figure 2 As shown, the terminal assembly 220 may also include a high-voltage terminal 222, a high-voltage cable 223, an interlocking terminal 224, a low-voltage cable 225 and a signal plug 226, etc. The component structure within the terminal assembly 220 and the specific connection method between the components may be any one of the prior art, and is not limited in this embodiment.

[0064] In this embodiment, in order to improve the strength of the elastic connecting arm 211, and thereby ensure the stability of the connecting assembly 200 and the connector plug shell 110 when plugged in, as shown in FIG. Figure 4 As shown, the elastic connecting arm 211 may include a straight arm portion 211a and two arc arm portions 211b, wherein the two arc arm portions 211b are located on both sides of the straight arm portion 211a in the first direction, so that the cross-section of the elastic connecting arm 211 perpendicular to the first direction is C-shaped.

[0065] In this embodiment, in order to facilitate the application of pressure to the elastic connecting arm 211, and thus facilitate the removal of the connecting assembly 200 from the connector plug shell 110, as shown in FIG. Figure 5 As shown, the elastic connecting arm 211 may be provided with an extension end 211c extending outside the connector plug shell 110. When a pressure away from the connector plug shell 110 is applied to the extension end 211c, the second limit portion 213 is released from the fourth limit portion 112, so that the connecting assembly 200 is released from the terminal installation cavity. In a specific implementation, in order to further facilitate the application of force, as shown in FIG. Figure 5As shown, the two elastic connecting arms 211 can be arranged opposite to each other.

[0066] In this embodiment, in order to further simplify the structure of the integrated electrical connector, especially the structure of the connector plug shell 110, as shown in FIG. Figure 3 and Figure 4 As shown, the second limiting portion 213 can be set as a limiting block 2131, and the fourth limiting portion 112 is the front end face of the connector plug shell 110 in the first direction. When the connecting component 200 is plugged into the terminal installation cavity along the first direction, the limiting block 2131 is stuck on the front end face.

[0067] In this embodiment, Figure 7 As shown, when a pressing force of 10N is applied to the two opposite elastic connecting arms 211 respectively, the second limiting portion 213 will be displaced by 0.52mm, and the second limiting portion 213 and the fourth limiting portion 112 will be disengaged, so that the connecting assembly 200 can be unlocked and removed smoothly.

[0068] In summary, the integrated electrical connector in this embodiment is configured such that the connector plug shell 110 is formed on the mounting base 100, and the terminal shell 210 in the connection assembly 200 has a first limiting portion 212 and a second limiting portion 213, and the connector plug shell 110 has a corresponding third limiting portion 111 and a fourth limiting portion 112, so that the connection assembly 200 can be directly plugged into the connector plug shell 110, and the two can be based on the first limiting portion 212, the second limiting portion 213, the third limiting portion 111 and the fourth limiting portion 112. Stable connection; at the same time, by setting the second limiting portion 213 to be located on the elastic connecting arm 211, it is convenient to plug the connecting component 200 into the connector plug shell 110, and it is also convenient to unfasten the connecting component 200 from the connector plug shell 110; thereby, the installation and maintenance convenience of the integrated electrical connector can be improved, and the molds of structural materials such as flanges and sealing rings on the electrical connector can be reduced, saving manufacturing costs; in addition, the connector plug shell 110 directly molded on the mounting base 100 can improve the shell strength of the integrated electrical connector.

Specifically, the elastic connection arm 211 can be formed by extending a portion of the connection ring 214 (a portion in an area other than the area where the connection platform 214a is located) in the first direction.

[0070] In this embodiment, Figure 3 and Figure 4 As shown, the portion of the connecting ring 214 protruding from the elastic connecting arm 211 can be used as the first limiting portion 212, and correspondingly, the third limiting portion 111 is a corresponding inner protrusion provided in the connector plug shell 110. That is, the platform formed by the reduction of the inner diameter of the connector plug shell 110 is the third limiting portion 111.

[0071] In this embodiment, a mounting groove is formed between the connecting ring 214 and the terminal shell 210 , and the shielding shell 221 in the terminal assembly 220 is inserted into the mounting groove.

[0072] In an optional specific implementation of this embodiment, as Figure 2-Figure 5 As shown, a shielding shell 221 may be provided including a shell-shaped body 221a, a first elastic arm 221b and a second elastic arm 221c, wherein the first elastic arm 221b is formed by the shell-shaped body 221a protruding inwardly and extending, and the second elastic arm 221c is formed by the front end of the shell-shaped body 221a in the first direction being bent outwardly and extending; a snap-fit ​​fixing groove 215 corresponding to the first elastic arm 221b is provided on the terminal shell 210; a avoidance groove 214b is provided on the connecting ring 214 corresponding to the second elastic arm 221c, and when the connecting assembly 200 is plugged into the terminal mounting cavity, the second elastic arm 221c abuts against the connector plug-in shell 110.

[0073] Specifically, there may be two first elastic arms 221 b, and the two first elastic arms 221 b may be arranged opposite to each other.

[0074] Specifically, there may be multiple second elastic arms 221c, and the connecting platform 214a on the connecting ring 214 may be disposed between the second elastic arms 221c, that is, a plug-in slot corresponding to the connecting platform 214a is formed between the second elastic arms 221c.

[0075] In an optional specific implementation of this embodiment, in order to improve the plug-in convenience between the connection component 200 and the connector plug shell 110, as shown in FIG. Figure 4 and Figure 5 As shown, the terminal shell 210 may be provided with a guide block 216, and correspondingly, the connector plug shell 110 may be provided with a corresponding guide groove 113; in specific implementation, two guide blocks 216 may be provided, and correspondingly, two guide grooves 113 may also be provided.

[0076] Specifically, in order to further improve the structural integrity of the terminal housing 210, as Figure 4 As shown, the guide block 216 can be integrally provided with two of the connecting platforms 214 a of the connecting ring 214 .
