[0018] In order to make the purpose, technical scheme and advantage of the utility model embodiment more clearly, the utility model technical scheme will be clearly and completely described below in conjunction with the embodiment.

[0019] EMBODIMENT

[0020] As shown in Figure 1 , Figure 2 and Figure 3 , capacitor lead-out electrode sheet, including shell 10 and metal sheet 20, the inner wall of shell 10 is fixedly connected with plug -in board 30, and metal sheet 20 is constituted by bending part 21, middle connecting part 22 and outer connecting part 23, and middle connecting part 22 is connected with bending part 21 and outer connecting part 23 respectively, and bending part 21 is hung on one side of shell 10 and is inserted with plug -in board 30, and the inside of bending part 21 is installed with the positioning mechanism of limiting the movement of plug -in board 30.

[0021] Specifically, the shell 10 is in the shape of "convex", the bottom is a mounting ear, the outer connecting part 23 is attached to the mounting ear, and the included angle between the outer connecting part 23 and the intermediate connecting part 22 is adapted to the included angle between the main body of the shell 10 and the mounting ear. By suspending the bent part 21 on the side wall of the shell 10, the side of the bent part 21 away from the intermediate connecting part 22 will extend to the inside of the shell 10. After being plugged with the plug-in plate 30, the plug-in plate 30 can limit the overall metal sheet 20 from deviating when the shell 10 is filled with epoxy resin, thereby improving product quality.

[0022] It should be noted that the bent part 21 is provided with a receiving cavity 211 in communication with the plug-in plate 30.

[0023] As shown in Figure 2 and Figure 3 , the positioning mechanism includes a sleeve 25, one end of the sleeve 25 movably sleeving a sleeve rod 26, one end of the plug-in plate 30 inside the receiving cavity 211 is provided with a positioning groove 31, and the sleeve rod 26 is plugged with the positioning groove 31.

[0024] Specifically, one end of the sleeve rod 26 close to the plug-in plate 30 is provided with an opening, so that after the plug-in plate 30 is inserted into the inside of the bent part 21, the inclined surface of the opening will be in contact with the plug-in plate 30. By pressure, the sleeve rod 26 will be pushed to the side, and when the sleeve rod 26 enters the inside of the positioning groove 31, the plug-in plate 30 will not be able to be pulled out.

[0025] As shown in Figure 3 , the outer circle of the sleeve rod 26 is fixedly sleeved with a baffle 27, one side of the baffle 27 is fixedly connected with an elastic element 28, and the elastic element 28 is fixedly connected with the sleeve 25.

[0026] Specifically, the elastic element 28 uses a spring, but is not limited to using a spring. The force of the elastic element 28 will always push the sleeve rod 26 to move away from the sleeve 25.

[0027] As shown in Figure 2 and Figure 3 , the outer wall of the bent part 21 is slidably connected with a push-pull element 24, and one end of the sleeve 25 away from the sleeve rod 26 is fixedly connected with the inner wall of the push-pull element 24.

[0028] Specifically, by pulling the push-pull element 24, the sleeve 25 can be moved together. When the sleeve 25 drives the sleeve rod 26 to move towards the end of the bent part 21, the inclined surface of the opening of the sleeve rod 26 will be in contact with the positioning groove 31, and finally the end of the sleeve rod 26 away from the sleeve 25 will be extruded out of the positioning groove 31.
