[0041] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, like reference numerals refer to like elements throughout the description. The following exemplary embodiments are not representative of all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure, as detailed in the appended claims.

[0042] Currently, board-end connectors are typically soldered onto circuit boards in vehicles to facilitate data transmission. However, board-end connectors in the related art cannot simultaneously achieve size reduction and connector reliability. For example, the housing of a board-end connector in the related art includes a housing structure and a board-end connector body. The housing structure includes a plastic part with a limiting cavity and a mounting cavity. The board-end connector body is disposed within the mounting cavity, and the limiting cavity can cooperate with the limiting portion of the wire-end connector to limit the wire-end connector. In the related art, the overall size of the board-end connector is typically reduced by thinning the sidewalls of the housing structure. However, due to the limitations of the housing structure material, thinning the sidewalls reduces the structural strength of the housing structure, thus preventing the board-end connectors in the related art from simultaneously achieving size reduction and connector reliability.

[0043] To address the aforementioned technical problems, this disclosure provides a board-end connector with a mounting cavity and a limiting cavity within a metal housing structure. The board-end connector body is disposed within the mounting cavity, and the limiting cavity engages with the limiting portion of the wire-end connector to limit its position. Thus, by incorporating a metal housing structure, the size of the board-end connector can be reduced without compromising the structural strength of the metal housing, thereby effectively improving the reliability of the board-end connector.

[0044] An exemplary embodiment of this disclosure provides a board-end connector, such as Figure 1 and Figure 2 As shown, the board-end connector 1 includes a metal housing structure 10 and a board-end connector body 14. The board-end connector body 14 is electrically connected to the circuit board 3. The metal housing structure 10 is provided with a mounting cavity 102 and a limiting cavity 101, which, in conjunction with... Figure 1 and Figure 11 The limiting cavity 101 is used to cooperate with the limiting part 22 of the wire end connector 2 to limit the wire end connector 2, thereby effectively improving the connection stability between the board end connector 1 and the wire end connector 2.

[0045] The board-end connector body 14 is disposed in the mounting cavity 102. The board-end connector body 14 is provided with a plug interface 141, which is used to connect with the wire-end connector 2. For example, the plug interface 141 can be a type-c interface, a USB interface, or a Lightning interface.

[0046] By setting the metal shell structure 10, on the one hand, the size of the board end connector 1 can be reduced, which is conducive to the miniaturization design of the board end connector 1 without affecting the structural strength of the metal shell structure 10, thereby effectively improving the reliability of the board end connector 1, and further improving the connection reliability and plug-pull reliability between the board end connector 1 and the line end connector 2. On the other hand, such a setting form also makes the structure of the board end connector 1 simple, which is convenient for production and processing, and also helps to reduce production costs.

[0047] It can be understood that reducing the size of the board end connector 1 means reducing the volume of the board end connector 1.

[0048] In the present embodiment, the board end connector 1 can be applied to the fields of vehicles, robots, industries, etc., without specific limitation.

[0049] In combination with Figure 1 , Figure 2 and Figure 3 , in an embodiment, the metal shell structure 10 includes a first metal shell 11, the first metal shell 11 is bent to form a containing groove 112 and a first inner cavity 111 with one end open, the containing groove 112 constitutes the mounting cavity 102, and the first inner cavity 111 constitutes the limiting cavity 101. By adopting such a setting form, the structure of the first metal shell 11 is simple, which is convenient for production and processing. In addition, while ensuring the structural strength of the metal shell structure 10, it is also conducive to further reducing the volume of the board end connector 1, thereby reducing the occupation of the area of the circuit board 3 and reducing the stacking space of the device. It has been verified that the board end connector 1 in the present embodiment can reduce the occupation of the area of the circuit board 3 by 50%.

[0050] The board end connector body 14 is embedded in the containing groove 112, and the open end of the first inner cavity 111 is used for the insertion of the limiting part 22 of the line end connector 2. In this way, the connection stability between the board end connector 1 and the line end connector 2 can be improved, thereby effectively improving the stability of data transmission. By embedding the board end connector body 14 in the containing groove 112, the board end connector body 14 can also be protected, thereby further improving the reliability of the board end connector 1.

[0051] In addition, the first metal shell 11 is further provided with a first connecting portion 117, which is used for connecting with the circuit board 3.

On the other hand, by connecting the first connecting portion 117 with the circuit board 3, the grounding of the first metal shell 11 can be realized, so as to not only improve the safety of the board end connector 1, but also avoid the electromagnetic interference on the board end connector body 14, and further improve the reliability of the board end connector 1.

At least one of the first side plates 114 is provided with a first extension portion. Exemplarily, the first extension portion can be arranged on only one of the first side plates 114, or can be arranged on both of the first side plates 114, so as to improve the stability of the fixed first metal shell 11. The first extension portion extends away from the first top plate 113, and the first extension portion constitutes the first connecting portion 117. By adopting such arrangement form, the arrangement of the first connecting portion 117 is simple, and the production and processing are facilitated.

[0053] In combination Figure 3 In an embodiment, the groove side wall of the accommodating groove 112 is connected with the first side plate 114 through a first bottom plate 115, the first bottom plate 115 is opposite to the first top plate 113, and the first bottom plate 115 is used for abutting connection with the circuit board 3. The first bottom plate 115 can be abutted and connected with the circuit board 3 through surface mounting technology (SMT), for example. In this way, the connecting area between the first metal shell 11 and the circuit board 3 can be increased through the two first bottom plates 115, the utilization of the first metal shell 11 is maximized, so as to further improve the connecting stability between the board end connector 1 and the circuit board 3, and further reduce the size of the board end connector 1.

By arranging the first back plate 116, the over-stretching of the wire end connector 2 into the board end connector 1 can be avoided, so as to improve the assembly convenience between the board end connector 1 and the wire end connector 2.

[0055] The two sides of the first back plate 116 extend to the two first side plates 114 respectively to be connected with the two first side plates 114. Exemplarily, the connection between the first back plate 116 and the first side plate 114 can be achieved by welding, bonding, clamping or the like. With such a setting form, the structural strength of the first metal shell 11 can be further improved, thereby effectively improving the reliability of the board end connector 1, and meanwhile, the increase of the volume of the board end connector 1 can be reduced, thereby being beneficial to the miniaturization design of the board end connector 1.

[0056] In combination with Figure 1 , Figure 2 and Figure 4 , in an embodiment, the metal shell structure 10 further comprises a second metal shell 12, the second metal shell 12 is formed by bending to have a second inner cavity 121 with one end being open, and the second metal shell 12 is sleeved outside the board end connector body 14 through the second inner cavity 121. In this way, on the one hand, the board end connector 1 can be protected, and meanwhile, the structural strength of the metal shell structure 10 can be improved, thereby further improving the reliability of the board end connector 1. On the other hand, the structure of the second metal shell 12 is simple, which is not only beneficial to production and processing, but also can reduce the increase of the volume of the board end connector 1, thereby being beneficial to the miniaturization design of the board end connector 1.

[0057] The second metal shell 12 is embedded in the accommodating groove 112 and connected with the first metal shell 11, for example, the connection between the first metal shell 11 and the second metal shell 12 can be achieved by welding, bonding, clamping or the like.

By providing the second connecting portion 126, on the one hand, the stability of the board end connector 1 fixed on the circuit board 3 can be further improved, thereby further ensuring the reliability of the board end connector 1. On the other hand, by connecting the second connecting portion 126 with the circuit board 3, the ground of the second metal shell 12 or the whole metal shell structure 10 can be realized, thereby not only improving the safety of the board end connector 1, but also avoiding the board end connector body 14 from being interfered by electromagnetic, thereby further improving the reliability of the board end connector 1.

[0058] In combination with Figure 3 and Figure 4In an embodiment, the second metal shell 12 comprises two second side plates 122 arranged oppositely, and at least one of the second side plates 122 is provided with a first limiting fitting part 1221. Exemplarily, the first limiting fitting part 1221 can be provided on only one of the second side plates 122, or can be provided on both of the second side plates 122. A second limiting fitting part 1121 is provided on the slot side wall of the accommodating slot 112 corresponding to the position of the first limiting fitting part 1221, and the first limiting fitting part 1221 cooperates with the second limiting fitting part 1121 to limit the movement of the second metal shell 12.

In this way, the connection mode between the first metal shell 11 and the second metal shell 12 is simple, which facilitates the processing and production, and can also reduce the increase of the volume of the board end connector 1, thereby being beneficial to the miniaturization design of the board end connector 1. In addition, the connection stability between the second metal shell 12 and the first metal shell 11 can be improved, thereby further improving the reliability of the board end connector 1.

[0063] The two sides of the second back plate 124 extend to the two second side plates 122 respectively, so as to be connected with the two second side plates 122 respectively.

In addition, it is also beneficial to reduce the increase of the volume of the board end connector 1, thereby facilitating the miniaturization design of the board end connector 1.

[0068] The third top plate 131 is provided with a limiting opening 1311 communicating with the first inner cavity 111, and the limiting opening 1311 is used for cooperating with the limiting portion 22 of the wire end connector 2.
