[0029] In view of this, an embodiment of the present application provides a connector, aiming to solve at least one of the above-mentioned technical problems.

[0030] A connector of the present application is described in detail below with reference to the accompanying drawings.

[0031] Ginseng Figure 1 and Figure 2 As shown, the connector of the embodiment of the present application includes a housing 10 , a main body 20 , a terminal assembly 30 and a connecting portion 40 .

[0032] Specifically, in the application embodiment, the housing 10 is provided with a through connection port 100, the main body 20 is connected to the housing 10, and has a receiving cavity 200 connected to the connection port 100, the main body 20 includes a mounting side wall 202, and a terminal lead-out port 201 connected to the receiving cavity 200 is provided on the mounting side wall 202, and the terminal lead-out port 201 is used for the second end 302 of the terminal assembly 30 to pass through; wherein the mounting side wall 202 is located at the connection between the main body 20 and the housing 10 On the adjacent side of one side, the terminal assembly 30 is inserted into the accommodating cavity 200, and the terminal assembly 30 is an L-shaped structure. Specifically, the terminal assembly 30 includes a first end 301 and a second end 302. The first end 301 is arranged at the connection port 100, and the second end 302 is arranged at the terminal lead-out port 201, and protrudes from the mounting side wall 202; the connecting portion 40 is connected to the mounting side wall 202, and protrudes relative to the mounting side wall 202 toward a side away from the main body 20, and the connecting portion 40 is used to connect with the circuit board. The connecting portion 40 provided on the mounting side wall 202 is connected to the circuit board. Compared with the direct connection between the mounting side wall 202 of the connector and the circuit board, the welding area of ​​the connecting portion 40 is relatively reduced, and it is easier to ensure the flatness, the positioning accuracy between the connecting portion 40 and the circuit board, and the stability after welding.

[0033] Ginseng Figure 2 and Figure 3 , Figure 4As shown, in one embodiment of the present application, the connection portion 40 has a connection surface 401 on the side away from the main body 20, and the connection surface 401 is used for welding with the circuit board. Considering that the flatness of the connection surface 401 is easier to ensure than the mounting side wall 202 of the connector main body 20, the connection surface 401 of the connection portion 40 is welded to the circuit board, so that the connector and the circuit board are more firmly fixed, the ground signal transmission is more stable, and the anti-interference ability is better.

[0034] Ginseng Figure 1 , Figure 2 , Figure 4 As shown, in one embodiment of the present application, the connector includes a plurality of spaced connection parts 40. The plurality of spaced connection parts 40 are connected to the circuit board, and the multi-point connection parts 40 can ensure a more stable connection between the connector and the circuit board, a higher welding accuracy, and a more stable signal transmission performance.

[0035] In one embodiment of the present application, at least one connecting portion 40 is disposed at the geometric center of the mounting side wall 202 (eg Figure 4 As shown), the remaining connection parts 40 are arranged around the connection part 40 located at the geometric center of the installation side wall 202. By arranging at least one connection part 40 at the geometric center of the installation side wall 202, the reliability of the connection between the connector and the circuit board is ensured, and its stability is better.

[0036] In one embodiment of the present application, the main body 20 has two terminal lead-out openings 201 spaced apart from each other, and the connector includes two terminal assemblies 30, wherein the second end 302 of each terminal assembly 30 is disposed at one terminal lead-out opening 201. Figure 4 As shown, at least one connection portion 40 is arranged at the geometric center of the mounting side wall 202, and the second ends 302 of the two terminal assemblies 30 are located on both sides of the connection portion 40 at the geometric center of the mounting side wall 202. On the one hand, the multi-channel expansion can meet the customer's multi-channel signal transmission needs, and at the same time, this layout is convenient for customers to install vehicles and wire and switch; on the other hand, the second ends 302 of the two terminal assemblies 30 and the connection portion 40 located at the geometric center of the mounting side wall 202 form a more stable fit with the circuit board, and the connection reliability is higher.

[0037] In one embodiment of the present application, at least one connecting portion 40 is provided on the mounting side wall 202 between any two adjacent terminal assemblies 30. By providing at least one connecting portion 40 on the mounting side wall 202 between any two adjacent terminal assemblies 30, after the second end 302 of the terminal assembly 30 passes through the circuit board, an effective connection can be formed with the circuit board through the connecting portion 40, thereby ensuring the accuracy of assembly positioning and the stability of the connection between the terminal assembly 30 and the circuit board.

[0038] Ginseng Figure 3 As shown, it should be understood that in one embodiment of the present application, the height of the connection surface 401 of the connection portion 40 from the mounting side wall 202 is h mm, wherein 0.4≤h≤0.6. h can be any value among 0.4, 0.5, 0.6 or a range value between any two values. Considering that the height of the bottom bracket is too long, it will affect the length of the second end 302 of the terminal assembly 30 exposed from the PCB board, and the height of the bottom bracket is too short, it will affect the later welding process. After the solder paste is applied, during the welding process of the connector and the circuit board, the solder paste overflows the connection surface 401, causing the mounting side wall 202 of the connector to be completely adhered to the circuit board. Due to the conductivity of the solder paste, it is easy to cause a short circuit in the circuit board. Considering that in the welding process, the thickness of the solder paste applied is generally 0.12 to 0.20 mm, therefore, when the value range of h is 0.4-0.6, the connection effect between the connector and the circuit board is relatively better.

[0039] Ginseng Figure 1 , Figure 2 as well as Figure 4 As shown, in one embodiment of the present application, the connector further includes a plurality of positioning posts 50, and the plurality of positioning posts 50 are all connected to the mounting side wall 202 and are evenly distributed around the geometric center of the mounting side wall 202. In one embodiment of the present application, three positioning posts 50 are provided and are evenly distributed around the geometric center of the mounting side wall 202. It can be understood that the three positioning posts 50 form a triangular distribution on the mounting side wall 202, and the stability of the triangular distribution is well guaranteed. At the same time, the three positioning posts 50 can save the number of parts on the one hand, and improve the assembly efficiency of the connector and the circuit board on the other hand.

[0040] In one embodiment of the present application, the connecting portion 40 and the main body 20 are integrally formed.

[0041] Accordingly, the present application also provides a vehicle, comprising the connector as described in the above embodiment. Therefore, the vehicle can have all the technical features and beneficial effects of the above connector, which will not be described in detail here.

For parts not described in detail in a certain embodiment, reference can be made to the relevant description of other embodiments. In the absence of conflict, the features in the above embodiments and implementation methods can be combined with each other.
