[0027] Embodiment 1
[0028] like Figure 1 As shown, a current extraction structure includes a connection terminal 10 and a connection terminal 2 11. The connection terminal 10 and the connection terminal 2 11 are respectively connected to an external device. The current extraction of the external device is achieved through the conduction between the connection terminal 10 and the connection terminal 2 11.
[0029] Among them, Figures 1 to 3 As shown, the connection terminal 2 11 includes a substrate 1, a contact plate 1 8, and a contact plate 2 9. The contact plate 1 8 and the contact plate 2 9 are relatively distributed on the substrate 1, and contact springs 903 are respectively installed on the sides of the contact plate 1 8 and the contact plate 2 9 facing each other. Figure 7 As shown, the structures of the contact plate 1 8 and the contact plate 2 9 are similar. At least one mounting groove 1 901 is installed on the opposite sides of the contact plate 1 8 and the contact plate 2 9 respectively. A guide rod 902 is arranged in the mounting groove 901. An inclined contact spring 903 is sleeved on the guide rod 902. The contact spring 903 is spirally shaped, and the spiral cross-section of the contact spring 903 is inclined. The contact spring 903 slides in the mounting groove 901 along the guide rod 902.
[0030] The contact plate 1 8 and the contact plate 2 9 are driven by the driving member 3 to move closer to or farther from each other on the substrate 1. The connection terminal 2 11 is connected to the connection terminal 10 through the contact plate 1 8 and the contact plate 2 9. The connection terminal 10 is provided with a contact terminal 1001. The contact plate 1 8 and the contact plate 2 9 are respectively located on both sides of the contact terminal 1001. The contact plate 1 8 and the contact plate 2 9 are in contact with or separated from the contact terminal 1001 as the driving member 3 is driven. Specifically, as Figure 8 As shown, the connection terminal 10 includes a cavity for accommodating the contact plate 1 8 and the contact plate 2 9, and the contact terminal 1001 is installed in the cavity. The side wall of the connection terminal 10 is provided with a through groove 1002 for electrically connecting the external device to the contact terminal 1001.
[0031] The driving member 3 can be a cylinder or an electric telescopic rod, and the contact plate 1 8, the contact plate 2 9 and the contact terminal 1001 are all made of conductive materials. The driving member 3 drives the contact plate 1 8 and the contact plate 2 9 to move, so that the contact plate 1 8 and the contact plate 2 9 are moved closer to each other to contact and connect with the contact terminal 1001 or move away from each other to separate and short-circuit the contact terminal 1001, thereby realizing the connection and disconnection between the connection terminal 10 and the connection terminal 2 11.
[0032] Specifically, when contact plate 1 8 and contact plate 2 9 approach each other and contact the contact terminal 1001, the contact spring 903 is squeezed and slides in the mounting groove 901 until the contact springs 902 on contact plate 1 8 and contact plate 2 9 are in stable contact with the contact terminal 1001, thereby realizing the connection between the connection terminal 10 and the connection terminal 2 11.
[0033] In addition, the contact plate 1 8 and the contact plate 2 9 are translated to achieve contact or disconnection with the contact terminal 1001, and the friction between the three is small, so the wear is small, which can effectively extend the service life of the structure. After the structure is installed, no additional reserved space is required when it is used, which is suitable for a variety of application scenarios and is easy to promote and use.
[0034] Specifically, Figure 2 , Figure 3 As shown, the contact plate 18 and the contact plate 29 are connected to the auxiliary plate 18 respectively, and the auxiliary plate 18 is in a T-shaped structure, and the two auxiliary plates 18 are distributed in a mirror image. The auxiliary plate 18 includes a first connection end and a second connection end, the first connection end is connected to the contact plate 18 or the contact plate 29, and the second connection end is slidably connected to the base plate 1 through the cooperation between the slider 2 13 and the slide rail 2 12, and a slot for the first connection end to extend out is provided on the base plate 1. Among them, the slider 2 13 is connected to the auxiliary plate 18, and the slide rail 2 12 is connected to the bottom of the base plate 1. Through the cooperation between the slider 2 13 and the slide rail 2 12, the auxiliary plate 18 can drive the contact plate 1 8 and the contact plate 2 9 to move along the Y axis.
[0035] In order to enable the driving member 3 to drive the contact plate 1 8 and the contact plate 2 9 to move, a slidable moving plate 7 is arranged on the base plate 1. Specifically, a slide rail 1 5 is installed on the base plate 1, and a slider 1 6 is installed on the moving plate 7. Through the cooperation between the slide rail 1 5 and the slider 1 6, the moving plate 7 can move along the X axis on the base plate 1. In addition, a connecting frame 4 is installed on the moving plate 7, and the driving end of the driving member 3 is connected to the connecting frame 4. The driving member 3 is installed on the base plate 1 through the fixing frame 2. When the driving member 3 is started, the driving end of the driving member 3 can drive the moving plate 7 to move through the connecting frame 4.
[0036] like Figure 3 , Figure 5 , Figure 6 As shown, the current lead-out structure also includes an adjusting member 14, which is connected to an auxiliary plate 18 to drive the contact plate 1 8 and the contact plate 2 9 to move along the Y axis. One end of the adjusting member 14 is connected to a clamping block 16, and a guide groove 2 17 is provided on the substrate 1. The clamping block 16 is located inside the guide groove 2 17, and the guide groove 2 17 is used to guide the clamping block 16 to move along the Y axis.
[0037] Furthermore, Figure 4As shown, a guide groove 15 is provided at the position of the movable plate 7 corresponding to the guide groove 2 17, and the clamping block 16 is located inside the guide groove 15. The guide groove 15 is used to drive the clamping block 16 to move so that the contact plate 1 8 and the contact plate 2 9 are closer to or farther away from each other.
[0038] Please refer to Figure 5 , start the driving member 3, the telescopic end of the driving member 3 extends out, pushing the movable plate 7 to move forward. At this time, the guide groove 15 pushes the clamping block 16 to move inward, so that the contact plate 1 8 and the contact plate 2 9 are close to each other, so that the contact plate 1 8 and the contact plate 2 9 are in contact with the contact terminal 1001, realizing the connection between the connection terminal 10 and the connection terminal 2 11.
[0039] When the telescopic end of the driving member 3 retracts, it drives the movable plate 7 to move backward. At this time, the guide groove 15 pushes the clamping block 16 to move outward, so that the contact plate 1 8 and the contact plate 2 9 move away from each other, thereby separating the contact plate 1 8 and the contact plate 2 9 from the contact terminal 1001, and disconnecting the connection terminal 10 and the connection terminal 2 11.
