Description

Technical Field

[0001] The present application relates to the technical field of connectors, and in particular to a connector terminal structure and a connector. Background Art

[0002] A connector is an electronic product that connects two active devices. It can transmit current or signals. Connectors play an increasingly important role today as electronic products become more functional and modular in design.

[0003] An existing common power connector includes a terminal and a plastic seat, wherein the terminal is fixed to the plastic seat and is used to be plugged into the docking terminal of the docking connector. The terminal is a single-body structure, which can be a male terminal or a female terminal. Generally speaking, when it is a male terminal, it usually has no elasticity, and when it is a female terminal, it has only a small amount of elasticity. In this way, when the power connector uses the terminal to plug into the docking terminal of the docking connector, the terminal is difficult to float in any direction of X / Y / Z, and thus cannot play an automatic guiding role based on the floating of the terminal when the terminal is plugged in, and it is difficult to tolerate the dimensional error and plugging accuracy of the terminal and the docking terminal. In the plugged state, since the terminal basically has no floating function, it cannot play a good shockproof function, which is not conducive to the reliable connection between the terminals when the product vibrates.

[0027] Specifically, a docking portion 111 is protruded upwardly from the middle of the first seat body 11 , and the docking portion 111 is used for plugging with the docking terminal 200 .

[0028] exist Figures 1 to 5 In the example, the connector terminal structure 100 is used as a male terminal, and the mating terminal 200 is a female terminal, but this is not limited to this.

By providing the plurality of elastic arms 211, sufficient elastic force can be provided to the movable terminal 1 to ensure the floating of the movable terminal 1 in the X / Y / Z directions, and the signal transmission capability between the movable terminal 1 and the static terminal 3 can be ensured. Of course, the form of the elastic member 2 is not limited thereto, and can also be any other form that can be thought of by a person skilled in the art, as long as it can conduct the movable terminal 1 and the static terminal 3 and can provide elastic force to the movable terminal 1 to ensure the floating of the movable terminal 1 in the X / Y / Z directions.

[0030] Specifically, the plurality of elastic arms 211 are formed by punching the bottom plate 21 upward.

[0031] Specifically, the outer end of each elastic arm 211 is connected to the bottom plate 21 , and the inner end of each elastic arm 211 forms the abutting portion 22 .

It should be noted that the elastic member 2 can be fixed on the static terminal 3, or it can be simply arranged on the static terminal 3 without being fixed, as long as it can be limited. For example, in a specific example, the elastic member 2 can be directly placed in the groove 311, and the bottom plate 21 can be limited by the side wall of the groove 311.

[0033] Embodiment 2

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

[0035] In the embodiment of the present application, relative to the single-body structure of the traditional terminal, the connector terminal structure 100 includes three components: a movable terminal 1, a static terminal 3 and an elastic member 2 conductively connected between the movable terminal 1 and the static terminal 3. The elastic member 2, on the one hand, enables conductivity between the movable terminal 1 and the static terminal 3, and on the other hand, enables the movable terminal 1 to float up and down. Therefore, when the connector terminal structure 100 is assembled to the connector 300 in a certain manner, the movable terminal 1 can float in the X / Y / Z directions, and thus, when plugged into the docking terminal 200, it is convenient for automatic guiding, and can allow the connector terminal structure 100 to have a certain dimensional error in the Z direction and the movable terminal 1 to have a certain dimensional error in the X / Y directions, can tolerate fault-matching accuracy, and can have a good shockproof effect. When the product vibrates, it is beneficial to ensure a reliable connection between the connector terminal structure 100 and the docking terminal 200.

[0036] In some embodiments, a terminal groove 41 is formed on the insulating housing 4, the connector terminal structure 100 is disposed in the terminal groove 41, and the movable terminal 1 and the side wall of the terminal groove 41 are spaced apart to enable the movable terminal 1 to float in the X / Y / Z directions.

[0037] In a specific example, the terminal slot 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 to the middle of the upper end of the wide portion 411, the second seat body 31 is fixed to the lower side of the wide portion 411, the first seat body 11 is movably arranged on the upper side of the wide portion 412 and is spaced from the side wall of the wide portion 411, the docking portion 111 is arranged on the narrow portion 412 and is spaced from the side wall of the narrow portion 412, and the step surface 413 between the wide portion 411 and the narrow portion 412 restricts the first seat body 11 in the wide portion 411. Since the first seat body 11 is movably arranged on the upper side of the wide portion 412 and is spaced from the side wall of the wide portion 411, and the docking portion 111 is arranged on the narrow portion 412 and is spaced from 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 directions can be achieved.

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

[0039] In a specific example, the connector terminal structure 100 in the connector 300 and the mating terminals 200 of the mating connector 5 are respectively provided in three numbers, but this is not limited thereto.

[0040] Specifically, the insulating shell 4 is provided with an anti-foolproof protrusion 42, and the docking connector 5 is provided with an anti-foolproof recess 51. When the connector 300 and the docking connector 5 are correctly plugged in, the anti-foolproof protrusion 42 can be inserted into the anti-foolproof recess 51. Otherwise, the anti-foolproof protrusion 42 cannot be inserted into the anti-foolproof recess 51, thereby playing an anti-foolproof role.

[0041] The above disclosure is only a preferred example of the present application, and its role is to facilitate the technical personnel in this field to understand and implement it. Of course, it cannot be used to limit the scope of rights of the present application. Therefore, equivalent changes made according to the scope of the patent application of the present application still fall within the scope covered by the present application.
