Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to an integrated electrical connector. Background Technology

[0002] With the rapid development of new energy vehicle technology and the increasing demand for longer driving range, the number and total power of electrical components in vehicles are constantly increasing, placing higher demands on the energy density of battery packs. This makes the limited space within the battery pack and high-voltage safety the biggest challenges. Ensuring the safe and reliable operation of electric vehicle high-voltage safety systems, integrated, miniaturized, and lightweight designs have become key technological development directions of interest in the industry.

[0003] High-voltage connectors are key components in the power transmission of electric vehicles. They include socket connectors and plug connectors. The socket connector is located on the battery pack panel and is electrically connected to the battery pack. The socket connector and plug connector are mated together. Currently, the connection between the socket connector and the panel is generally achieved by setting a connecting flange on the socket connector housing, screwing the connecting flange to the flange structure on the panel, and placing a sealing ring between them. However, this method has the problems of inconvenient installation and maintenance, and high manufacturing costs. Utility Model Content

[0004] Therefore, in order to overcome the above problems, this utility model provides an integrated electrical connector in which the connector housing is directly formed on the mounting base, and the connecting components inside the electrical connector are inserted into the connector housing, which can save installation and manufacturing costs.

[0005] Therefore, this utility model provides an integrated electrical connector, comprising:

[0006] The mounting base is suitable for installation at the external connection port of the active device corresponding to the integrated electrical connector; the mounting base is formed with a connector insertion shell, and the connector insertion shell has a terminal mounting cavity.

[0007] A connecting assembly includes a terminal housing and a terminal assembly, wherein the terminal assembly is disposed inside the terminal housing; a pair of elastic connecting arms are fixed on the outside of the terminal housing; a first limiting part is provided on the terminal housing, a second limiting part is provided on the elastic connecting arms, and a third limiting part and a fourth limiting part are respectively provided on the connector plug housing corresponding to the first limiting part and the second limiting part;

[0008] When the connecting component is inserted into the terminal mounting cavity along the first direction, the first limiting part and the third limiting part abut against each other to restrict the movement of the connecting component in the first direction, and the second limiting part and the fourth limiting part abut against each other to restrict the movement of the connecting component in the second direction; the second direction is the opposite direction to the first direction.

[0009] Optionally, the flexible connecting arm includes a straight arm portion and two arc-shaped arm portions, the two arc-shaped arm portions being located on both sides of the straight arm portion in a first direction.

[0010] Optionally, the second limiting part is a limiting block, and the fourth limiting part is the front end face of the connector insertion shell in the first direction. When the connecting component is inserted into the terminal mounting cavity in the first direction, the limiting block is engaged with the front end face.

[0011] Optionally, a connecting ring is provided on the periphery of the terminal housing, and the connecting ring is fixed to the terminal housing by at least two spaced connecting platforms; an elastic connecting arm is provided on the connecting ring.

[0012] Optionally, the portion of the connecting ring protruding outward from the elastic connecting arm is the first limiting portion; the third limiting portion is the corresponding inner protrusion provided inside the connector housing.

[0013] Optionally, a mounting groove is formed between the connecting ring and the terminal housing, and the shielding shell inside the terminal assembly is inserted into the mounting groove.

[0014] Optionally, the shielding shell includes a shell-shaped body, a first elastic arm, and a second elastic arm. The first elastic arm is formed by the shell-shaped body extending inward, and the second elastic arm is formed by the shell-shaped body bending outward at its front end in a first direction. The terminal shell is provided with a snap-fit ​​fixing groove corresponding to the first elastic arm. The connecting ring is provided with a clearance groove corresponding to the second elastic arm. When the connecting component is inserted into the terminal mounting cavity, the second elastic arm abuts against the connector insertion shell.

[0015] Optionally, the resilient connecting arm has an extended end that extends beyond the connector housing. When pressure is applied to the extended end away from the connector housing, the second limiting portion disengages from the fourth limiting portion, thereby disengaging the connecting assembly from the terminal mounting cavity.

[0016] Optionally, a guide block is provided on the terminal housing, and a corresponding guide groove is provided on the connector insertion housing.

[0017] The technical solution of this utility model has the following advantages:

[0018] The integrated electrical connector provided by this utility model features a connector housing molded onto a mounting base, and a first and second limiting portion on the terminal shell of the connecting assembly. The connector housing also has corresponding third and fourth limiting portions, allowing the connecting assembly to be directly inserted into the connector housing and securely connected based on these limiting portions. Furthermore, the second limiting portion is located on an elastic connecting arm, facilitating both insertion and release of the connecting assembly from the connector housing. This improves the ease of installation and maintenance of the integrated electrical connector, reduces the need for molds for flanges and sealing rings, and saves manufacturing costs. Additionally, the connector housing, directly molded onto the mounting base, enhances the overall strength of the integrated electrical connector. Attached Figure Description

Moreover, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0054] Please refer to Figures 1-5 This is a schematic diagram of an integrated electrical connector provided in an embodiment of the present invention. The integrated electrical connector includes a mounting base 100 and a connecting component 200.

[0055] Please refer to Figure 1 The mounting base 100 is suitable for installation at the external connection port of the active device corresponding to the integrated electrical connector. The mounting base 100 has a connector insertion shell 110 formed on it, and the connector insertion shell 110 has a terminal mounting cavity inside.

[0056] Specifically, active devices can be battery packs or signal-related active devices.

[0057] Specifically, in this embodiment, the integrated electrical connector is a socket connector, and one end of the integrated electrical connector on the outside of the mounting base 100 (the outside of the mounting base 100 after it is mounted on the active device) is adapted to be plugged into a corresponding plug connector.

[0058] Specifically, such as Figure 1 As shown, a snap-fit ​​boss 114 is provided on one end of the connector housing 110 on the outside of the mounting base 100 (also referred to as the rear end in the first direction below). The snap-fit ​​boss 114 is adapted to engage with a corresponding snap hook in the plug connector so that the integrated electrical connector in this embodiment is securely connected to the corresponding plug connector.

[0059] Please refer to Figures 2-4 The connecting assembly 200 includes a terminal housing 210 and a terminal assembly 220, with the terminal assembly 220 disposed inside the terminal housing 210. A pair of elastic connecting arms 211 are fixed to the outside of the terminal housing 210. A first limiting part 212 is provided on the terminal housing 210, and a second limiting part 213 is provided on the elastic connecting arms 211. A third limiting part 111 and a fourth limiting part 112 are respectively provided on the connector insertion housing 110 corresponding to the first limiting part 212 and the second limiting part 213.

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

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

[0062] Specifically, such as 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 of the existing methods, or the sleeve connection method provided in the following description of this embodiment.

[0063] Specifically, such as Figure 2 As shown, the terminal assembly 220 may also include a high-voltage terminal 222, a high-voltage cable 223, an interlock 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 can be any of the existing technologies, and no limitation is imposed in this embodiment.

[0064] In this embodiment, in order to improve the strength of the elastic connecting arm 211 and thus ensure the stability of the connecting assembly 200 when it is inserted into the connector housing 110, such as... Figure 4 As shown, the elastic connecting arm 211 can be configured to include a straight arm portion 211a and two arc arm portions 211b, with the two arc arm portions 211b 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, to facilitate applying pressure to the elastic connecting arm 211, and thus to facilitate removing the connecting assembly 200 from the connector housing 110, as follows: Figure 5 As shown, the elastic connecting arm 211 can be configured to have an extended end 211c extending beyond the connector housing 110. When pressure is applied to the extended end 211c away from the connector housing 110, the second limiting part 213 disengages from the fourth limiting part 112, causing the connecting assembly 200 to disengage from the terminal mounting cavity. In specific implementations, to further facilitate the application of force, such as... Figure 5As shown, the two elastic connecting arms 211 can be arranged opposite each other.

[0066] In this embodiment, to further simplify the structure of the integrated electrical connector, especially the structure of the connector housing 110, such as... Figure 3 and Figure 4 As shown, the second limiting part 213 can be set as a limiting block 2131, and the fourth limiting part 112 is the front end face of the connector insertion shell 110 in the first direction. When the connecting component 200 is inserted into the terminal mounting cavity in the first direction, the limiting block 2131 is engaged with the front end face.

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

[0068] In summary, the integrated electrical connector in this embodiment, by setting the connector insertion shell 110 to be formed on the mounting base 100, and setting the terminal shell 210 in the connecting assembly 200 to have a first limiting part 212 and a second limiting part 213, and the connector insertion shell 110 having corresponding third limiting parts 111 and fourth limiting parts 112, allows the connecting assembly 200 to be directly inserted into the connector insertion shell 110, and the two can be based on the first limiting part 212, the second limiting part 213, the third limiting part 111, and the fourth limiting part 112. The connection is secure; at the same time, by setting the second limiting part 213 on the elastic connecting arm 211, it is easy to insert the connecting component 200 into the connector socket shell 110, and it is also easy to unfasten the connecting component 200 from the connector socket shell 110; thereby, the installation and maintenance convenience of the integrated electrical connector can be improved, and the molds for structural materials such as flanges and sealing rings on the electrical connector can be reduced, saving manufacturing costs; in addition, the connector socket shell 110, which is directly formed on the mounting base 100, can improve the shell strength of the integrated electrical connector.

[0069] In one optional embodiment of this example, in order to improve the overall integrity of the peripheral structure of the terminal housing 210, such as... Figure 4 As shown, a connecting ring 214 can be provided on the periphery of the terminal housing 210. The connecting ring 214 is fixed to the terminal housing 210 by at least two spaced connecting platforms 214a. An elastic connecting arm 211 is provided on the connecting ring 214. Specifically, the elastic connecting arm 211 can be formed by extending a portion of the connecting ring 214 (the portion in the area other than the area where the connecting platform 214a is located) outward in a first direction.

[0070] In this embodiment, as Figure 3 and Figure 4 As shown, the portion of the connecting ring 214 that protrudes outward from the elastic connecting arm 211 can be considered as the first limiting portion 212. Correspondingly, the third limiting portion 111 is the inner protrusion provided inside the connector housing 110. That is, the platform formed by the reduction of the inner diameter of the connector housing 110 is the third limiting portion 111.

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

[0072] In one optional specific implementation of this embodiment, such as Figures 2-5 As shown, the shielding shell 221 can be provided with a shell-shaped body 221a, a first elastic arm 221b and a second elastic arm 221c. The first elastic arm 221b is formed by the shell-shaped body 221a extending inward, and the second elastic arm 221c is formed by the shell-shaped body 221a extending outward from the front end in the first direction. The terminal shell 210 is provided with a snap-fit ​​fixing groove 215 corresponding to the first elastic arm 221b. The connecting ring 214 is provided with a clearance groove 214b corresponding to the second elastic arm 221c. When the connecting component 200 is inserted into the terminal mounting cavity, the second elastic arm 221c abuts against the connector insertion shell 110.

[0073] Specifically, there can be two first spring arms 221b, and the two first spring arms 221b can be arranged relative to each other.

[0074] Specifically, there can be multiple second spring arms 221c, and the connecting platform 214a on the connecting ring 214 can be set between the second spring arms 221c, that is, the second spring arms 221c form a plug-in groove corresponding to the connecting platform 214a.

[0075] In one optional embodiment of this invention, to improve the ease of insertion between the connecting component 200 and the connector housing 110, such as... Figure 4 and Figure 5 As shown, the terminal housing 210 can be provided with a guide block 216, and correspondingly, the connector insertion housing 110 is provided with a guide groove 113. In specific implementation, there can be two guide blocks 216 and two guide grooves 113.

[0076] Specifically, in order to further improve the overall structural integrity of the terminal housing 210, such as Figure 4 As shown, the guide block 216 and two of the connecting platforms 214a of the connecting ring 214 can be integrated into one unit.

[0077] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
