It is necessary to press the finger on the terminal to unplug it, which will cause the terminal to be displaced or even damaged by external force, resulting in poor contact, signal interference and failure, affecting the quality and reliability of the connection. At the same time, the terminal can rotate freely, and the connection between the terminal and the wiring harness is easy to bend when installing the wiring harness, causing the terminal to be damaged.

[0029] In view of this, the connector of the embodiment of the present application includes a terminal assembly, a shell and a locking piece. The terminal assembly includes a terminal body and a connecting portion connected to each other, the terminal body extends along a first direction, and the connecting portion is used to connect a wiring harness. The shell includes a main body and an extension portion connected to each other, the main body has a first accommodating cavity, and the terminal body is arranged in the first accommodating cavity; along the second direction, the extension portion is arranged on one side of the main body, and the second direction intersects with the first direction. The locking piece is connected to the extension portion, and a second accommodating cavity connected to the first accommodating cavity is formed between the extension portion and the shell, and the connecting portion is arranged in the second accommodating cavity. In this way, when plugging and unplugging the connector, it can be against the extension portion to avoid contact with the terminal assembly, so that the terminal assembly is displaced or damaged when subjected to external force. The setting of the locking piece can partially limit the terminal assembly, thereby improving the stability and reliability of the connector.

[0030] The connector and the vehicle of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can be combined with each other.

Figure 2 It is a structural schematic diagram of a connector according to another embodiment of the present application. Figure 3 This is a structural schematic diagram of a connector according to another embodiment of the present application. Figure 4 is an exploded view of a connector according to an embodiment of the present application.

The shell 3 includes a body 30 and an extension portion 31 connected to each other, the body 30 has a first accommodating cavity 300, and the terminal body 10 is inserted into the first accommodating cavity 300. Such a configuration can prevent the terminal body 10 from moving radially in the first accommodating cavity 300. Along the second direction Y, the extension portion 31 is arranged on one side of the body 30, and the second direction Y intersects with the first direction X. The extension portion 31 can be a gripping end when plugging and unplugging the connector. The extension portion 31 is formed by extending in the second direction Y to increase the contact area between the user's hand and the connector, thereby preventing the user from placing his hand against the terminal assembly 1 for plugging and unplugging, and preventing the terminal assembly 1 from being displaced or damaged when subjected to external force. The locking member 4 is connected to the extension portion 31, and forms a second accommodating cavity 5 communicating with the first accommodating cavity 300 with the housing 3, and the connecting portion 11 is disposed through the second accommodating cavity 5.

There are two second connecting portions 42, and the connecting portion 11 of the terminal assembly 1 is sandwiched between the two second connecting portions 42, the first connecting portion 41 and the extension portion 31. In this way, the displacement of the connecting portion 11 in its radial direction can be limited, thereby improving the stability and reliability of the connector.

[0035] In some embodiments, the body 30 includes a third clamping portion, the first connecting portion 41 includes a fourth clamping portion, and the third clamping portion and the fourth clamping portion are clamped to connect the locking member 4 and the body 30.
