[0022] In order to make the above objectives, features and advantages of the present application more apparent, specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a number of different ways from those described herein without departing from the scope of the present application and it is understood that variations can be made in view of what is described and understood in the art. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0023] Embodiment One

[0024] Please refer to Figure 1 and Figure 2 The embodiment of the present application discloses a connector terminal structure 100, which comprises a movable terminal 1, an elastic member 2 and a fixed terminal 3. The movable terminal 1 is used to abut against a mating terminal 200. The movable terminal 1 and the fixed terminal 3 are arranged oppositely. The elastic member 2 is arranged between the movable terminal 1 and the fixed terminal 3 and conducts the movable terminal 1 and the fixed terminal 3. The elastic member 2 comprises an abutting part 22 which abuts against the lower side of the movable terminal 1 so as to enable the movable terminal 1 to float up and down.

[0025] In this embodiment, compared to the single-unit structure of traditional terminals, the connector terminal structure 100 includes three components: a moving terminal 1, a stationary terminal 3, and an elastic element 2 that conductively connects the moving terminal 1 and the stationary terminal 3. The elastic element 2 enables conductivity between the moving terminal 1 and the stationary terminal 3 and allows the moving terminal 1 to float up and down. Thus, when the connector terminal structure 100 is assembled to the connector 300 in a certain way, the moving terminal 1 can float in the X / Y / Z directions. This facilitates automatic guidance when it is plugged into the mating terminal 200, and allows for a certain dimensional error in the Z direction of the connector terminal structure 100 and a certain dimensional error in the X / Y directions of the moving terminal 1. It can tolerate the mating accuracy and has a good shockproof effect. When the product vibrates, it helps to ensure a reliable connection between the connector terminal structure 100 and the mating terminal 200.

[0026] In some embodiments, the moving terminal 1 includes a first base 11, the stationary terminal 3 includes a second base 31, the first base 11 and the second base 31 are arranged opposite each other, and the elastic member 2 is disposed between the first base 11 and the second base 31.

[0027] Specifically, the first base 11 has a docking part 111 protruding upward from the middle, which is used to connect with the docking terminal 200.

[0028] exist Figures 1 to 5 In the example, connector terminal structure 100 is used as a male terminal, and mating terminal 200 is a female terminal, but this is not a limitation. Figure 6 and Figure 7 In the example shown, connector terminal structure 100 is used as a female terminal, and mating terminal (not shown) is a male terminal.

[0029] Specifically, the elastic element 2 includes a base plate 21 disposed on the second base 31 and a plurality of spring arms 211 circumferentially distributed on the base plate 21, each of the plurality of spring arms 211 having an abutment portion 22. The arrangement of the plurality of spring arms 211 ensures that sufficient elastic force is provided to the moving terminal 1 to ensure its floating in the X / Y / Z directions, and also ensures the signal transmission capability between the moving terminal 1 and the stationary terminal 3. Of course, the form of the elastic element 2 is not limited to this; it can be any other form that can be conceived by those skilled in the art, as long as it can conduct the connection between the moving terminal 1 and the stationary terminal 3 and provide elastic force to the moving terminal 1 to ensure its floating in the X / Y / Z directions.

[0030] Specifically, multiple spring arms 211 are formed by pressing the base plate 21 upward.

[0031] Specifically, the outer end of each spring arm 211 is connected to the base plate 21, and the inner end of each spring arm 211 forms an abutment part 22.

[0032] Specifically, the second seat body 31 includes an upper surface, the upper surface is formed with a groove 311, the bottom plate 21 is arranged in the groove 311, and the abutting portion 22 is upwardly beyond the upper surface. It should be noted that the elastic piece 2 can be fixed on the static terminal 3, or can be only arranged on the static terminal 3 without being fixed, as long as it can be limited, for example, in the specific example, the elastic piece 2 is directly placed in the groove 311, and the bottom plate 21 can be limited by the side wall of the groove 311.

[0033] Embodiment two

[0034] Please combine Figures 1 to 5 The embodiment of the application discloses a connector 300, which comprises an insulating shell 4 and a connector terminal structure 100 as described above, the connector terminal structure 100 is arranged in the insulating shell 4, and the static terminal 3 is fixed on the insulating shell 4.

[0035] In the embodiment of the application, compared with the single-piece structure of the conventional terminal, the connector terminal structure 100 comprises three components, i.e., the dynamic terminal 1, the static terminal 3 and the elastic piece 2 connected between the dynamic terminal 1 and the static terminal 3, the elastic piece 2 is used to conduct between the dynamic terminal 1 and the static terminal 3 on one hand, and is used to make the dynamic terminal 1 float up and down on the other hand, so that the dynamic terminal 1 can float in the X / Y / Z direction when the connector terminal structure 100 is assembled to the connector 300 in a certain way, thereby facilitating automatic guiding when the connector terminal structure 100 is inserted with the mating terminal 200, and being able to tolerate a certain dimensional error of the connector terminal structure 100 in the Z direction and a certain dimensional error of the dynamic terminal 1 in the X / Y direction, so that the insertion accuracy can be fault-tolerant, and a better shockproof effect can be achieved, which is beneficial to guarantee the reliable connection between the connector terminal structure 100 and the mating terminal 200 when the product is shaken.

[0036] In some embodiments, the insulating shell 4 is formed with a terminal groove 41, the connector terminal structure 100 is arranged in the terminal groove 41, and the dynamic terminal 1 and the side wall of the terminal groove 41 are arranged in a spaced manner to enable the dynamic terminal 1 to float in the X / Y / Z direction.

[0037] In a specific example, the terminal groove 41 includes a wide portion 411 located at the lower side and a narrow portion 412 located at the upper side, the narrow portion 412 is connected at the upper end of the middle of the wide portion 411, the second seat body 31 is fixed at the lower side of the wide portion 411, the first seat body 11 is movably arranged at the upper side of the wide portion 412 and is arranged in a spaced manner with the side wall of the wide portion 411, the butt joint portion 111 is arranged in the narrow portion 412 and is arranged in a spaced manner with the side wall of the narrow portion 412, and the stepped surface 413 between the wide portion 411 and the narrow portion 412 limits the first seat body 11 in the wide portion 411. Because the first seat body 11 is movably arranged at the upper side of the wide portion 412 and is arranged in a spaced manner with the side wall of the wide portion 411, and the butt joint portion 111 is arranged in the narrow portion 412 and is arranged in a spaced manner with the side wall of the narrow portion 412, under the action of the elastic member 2, the floating of the movable terminal 1 in the X / Y / Z direction can be realized.

[0038] Specifically, the butt joint portion 111 is cylindrical, the diameter of the narrow portion 412 is set to be 1mm larger than that of the butt joint portion 111, the first seat body 11 is cylindrical, the diameter of the first seat body 11 is larger than that of the butt joint portion 111, and the diameter of the wide portion 411 is set to be 1mm larger than that of the first seat body 11. The cylindrical arrangement of the butt joint portion 111 and the first seat body 11 is more conducive to the floating of the movable terminal 1 in the XY direction. Of course, the butt joint portion 111 and the first seat body 11 can also be arranged in other shapes, and the shape of the terminal groove 41 is also not limited.

[0039] In a specific example, the connector terminal structure 100 in the connector 300 and the butt joint terminal 200 of the butt joint connector 5 are respectively arranged as 3, but it is not limited to this.

[0040] Specifically, the insulating shell 4 is provided with a foolproof convex portion 42, the butt joint connector 5 is provided with a foolproof concave portion 51, when the connector 300 is correctly plugged with the butt joint connector 5, the foolproof convex portion 42 can be clamped into the foolproof concave portion 51, otherwise, the foolproof convex portion 42 cannot be clamped into the foolproof concave portion 51, which plays a role of foolproof.

[0041] The above disclosure is only a preferred example of the present application, which is to facilitate the understanding and implementation of those skilled in the art, and of course cannot limit the scope of the right of the present application, therefore the equivalent changes made according to the application scope of the present application still belongs to the scope covered by the present application.
