[0028] The terms used in the implementation method part of this application are only used to explain the specific embodiments of this application, and are not intended to limit this application. The implementation method of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0029] like Figure 1 and Figure 2 As shown, a PCB board contact connector includes a bottom shell 1, an upper cover 2, a movable terminal 3 and a fixed terminal 4. The bottom shell 1 and the upper cover 2 can be covered up and down to form a mounting portion 5, and the movable terminal 3 and the fixed terminal 4 are arranged in the mounting portion 5.

[0030] like Figure 5 As shown, the movable terminal 3 includes a main body portion 31 and a first contact portion 32 bent upward and extended from the right side of the main body portion 31, the main body portion 31 is spring-shaped, the bottom of the main body portion 31 is connected to the fixed terminal 4 installed in the bottom shell 1, and the first contact portion 32 of the upper cover 2 corresponding to the movable terminal 3 is provided with a through groove 21, and the upper end of the first contact portion 32 extends out of the through groove 21.

[0031] The main body 31 of the movable terminal 3 of the present application is spring-shaped, and the spring-shaped main body 31 is designed to have good elasticity, and can provide a stable connection in the case of frequent plugging and unplugging; in addition, the first contact portion 32 is bent upward and extended from the right side of the main body 31, and the first contact portion 32 can provide a larger compressible height, that is, the connector can allow a larger deformation when connected. When it is necessary to adapt to equipment or components of different sizes or thicknesses, the connector can provide a larger plugging and unplugging range, which is suitable for the demand for higher compressible height; and the design of the first contact portion 32 of the movable terminal 3 of the present application makes the connector suitable for both vertical plugging and unplugging and horizontal plugging and unplugging. This versatility makes the connector more flexible and can provide reliable connection in usage scenarios in different directions.

[0032] like Figure 6 As shown, in this embodiment, the rear end of the first contact portion 32 extends to the left to form a first limiting portion 33, and the first contact portion 32 cooperates with the top wall of the upper cover 2 through the first limiting portion 33 to limit the upward reset height of the first contact portion 32. The first limiting end ensures that the movable terminal 3 can maintain a specific height when resetting, which can help maintain the stability and reliability of the connector.

[0033] like Figure 6 As shown, in this embodiment, the left end of the main body 31 extends backward and then bends and extends upward to form a second limiting portion 34. When the first contact portion 32 is subjected to a force from the front to the back, the second limiting portion 34 can limit the rotation of the main body 31.

[0034] like Figure 3 As shown, in this embodiment, a first mounting groove 22 for mounting the main body 31 is disposed inside the upper cover 2 .

[0035] like Figure 2 As shown, in this embodiment, a first snap-fit ​​portion 23 is provided on the side of the upper cover 2, and a second snap-fit ​​portion 11 is provided on the side of the bottom shell 1 corresponding to the first snap-fit ​​portion 23, and the upper cover 2 is snapped onto the second snap-fit ​​portion 11 of the bottom shell 1 through the first snap-fit ​​portion 23.

[0036] like Figure 2 As shown, in this embodiment, a third buckle portion 24 is further provided on the side of the upper cover 2. Through the third buckle portion 24, the connector can be more firmly fixed when in use, reducing the influence of external vibration or impact on the connector.

[0037] like Figure 2As shown, in this embodiment, a terminal protection portion 25 is provided on the front side of the upper cover 2, and the terminal protection portion 25 covers the portion of the fixed terminal 4 extending from the front side of the upper cover 2. The terminal protection portion 25 covers the portion of the fixed terminal 4 extending from the front side of the upper cover 2, which plays a role in protecting the terminal and preventing direct contact and damage to the terminal by external objects or touch.

[0038] like Figure 2 As shown, in this embodiment, the side of the bottom shell 1 is provided with a limiting protrusion 12. The limiting protrusion 12 on the side of the bottom shell 1 cooperates with the third buckle portion 24 of the upper cover 2 to provide an additional limiting effect to ensure the correct assembly of the connector.

[0039] like Figure 1 As shown, in this embodiment, a limiting column 13 is provided at the bottom of the bottom shell 1. The limiting column 13 at the bottom of the bottom shell 1 can provide bottom structural support for the bottom shell 1, thereby increasing the stability of the overall connector.
