[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figures 1 to 4 The utility model provides a vehicle rectifier diode: comprising a chip 1, an electrode and two groups of wire posts 5, wherein the electrode is composed of a negative electrode 2 and a positive electrode 3, and the negative electrode 2 and the positive electrode 3 are respectively arranged on the upper and lower sides of the chip 1, and the two wire posts 5 are respectively abutted against the opposite sides of the negative electrode 2 and the positive electrode 3, and the opposite ends of the two groups of wire posts 5 are both provided with a circular base to increase the contact area;

[0026] like Figure 1 , Figure 2 as well as Figure 3As shown, in order to keep the screwing length of the two groups of outer sealing shells 8 consistent when they are threadedly connected with the inner sealing shell 4, the chip 1 and the outer wall of the electrode are jointly covered with the inner sealing shell 4, and the upper and lower sides of the inner sealing shell 4 are both threadedly connected with the outer sealing shell 8. A limiting structure for limiting the position of the outer sealing shell 8 is arranged between the outer wall of the inner sealing shell 4 and the two groups of outer sealing shells 8. The limiting structure includes a limiting ring 9 and two groups of steps 16. The two groups of steps 16 are respectively arranged on the inner side walls of the two groups of outer sealing shells 8 and are close to the opposite end. The limiting ring 9 is arranged on the outer wall of the inner sealing shell 4 and is located in the middle position of the inner sealing shell 4 in the upper and lower directions. Through the limiting of the limiting ring 9 and the step 16, the two groups of outer sealing shells 8 can be positioned when they are threadedly connected with the inner sealing shell 4 separately, so that the position is fixed each time when installed, which can ensure that the pressing force on the wire column 5 is consistent each time, and the vertical groove 11 can be relative to each other.

[0027] like Figure 1 , Figure 2 As shown, in order to protect the close contact between the wire post 5 and the electrode, a clamping structure for keeping the wire post 5 and the electrode in close contact is provided between the outer sealing shell 8 and the wire post 5, and the clamping structure includes a clamping sleeve 6 and an elastic insulator 7. The clamping sleeve 6 is sleeved on the outer wall of the wire post 5, and the elastic insulator 7 is provided between the clamping sleeve 6 and the inner wall of the outer sealing shell 8. When the outer sealing shell 8 is threadedly connected with the inner sealing shell 4, the clamping sleeve 6 and the wire post 5 are pressed toward the electrode through the elastic insulator 7. The clamping sleeve 6 is sleeved on the outer wall of the wire post 5. When the outer sealing shell 8 is threadedly connected with the inner sealing shell 4, the elastic insulator 7 is squeezed, and the clamping sleeve 6 is driven to press the circular base of the wire post 5 toward one end of the electrode during the squeezing, thereby pressing the wire post 5 against the electrode;

[0028] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4 The outer wall of the two sets of outer sealing shells 8 is provided with a rotation-stopping structure for preventing the two sets of outer sealing shells 8 from rotating and loosening during use. The rotation-stopping structure includes a rotation-stopping pin 12 and two sets of vertical grooves 11, which are respectively arranged on the outer walls of the two sets of outer sealing shells 8 and are arranged opposite to each other up and down. The rotation-stopping pin 12 is rotatably connected to the inner side wall of the upper set of vertical grooves 11 in the two sets of vertical grooves 11 through the rotating shaft, and the outer wall of the end of the rotation-stopping pin 12 away from the rotating shaft is provided with a semi-spherical boss 13, and the inner side wall of the lower set of the two sets of vertical grooves 11 is provided with a positioning groove 15 corresponding to the semi-spherical boss 13. The end of the rotation-stopping pin 12 away from the rotating shaft is provided with a groove 14 for conveniently buckling the rotation-stopping pin 12 from the vertical groove 11. After the two sets of outer sealing shells 8 are connected to the inner sealing shell 4 in place, the rotation-stopping pin 12 is stuck between the two sets of vertical grooves 11, so as to stop the outer sealing shell 8 from rotating, thereby ensuring the safety during use.

[0029] like Figure 1 , Figure 2 As shown, in order to facilitate confirmation of polarity during use, a marking ring 10 for marking the direction of the negative electrode is provided on the upper side of the two groups of outer sealing shells 8 and the outer wall of the inner sealing shell 4 and near the upper end. Both groups of marking rings 10 are blue ring marks. When installing the outer sealing shell 8, the group of outer sealing shells 8 with the marking ring 10 is installed on the end of the inner sealing shell 4 with the marking ring 10. The negative electrode can be easily identified through the blue marking ring 10.

[0030] Working principle: Through the limiting of the limiting ring 9 and the step 16, the two sets of outer sealing shells 8 can be positioned when they are separately connected with the inner sealing shell 4 by thread, so that the position is fixed each time when installed, which can ensure that the pressing force on the wire column 5 is consistent each time, and the vertical groove 11 is relative to each other. When the outer sealing shell 8 is connected with the inner sealing shell 4 by thread, the compression sleeve 6 and the wire column 5 are pressed toward the electrode through the elastic insulator 7. The compression sleeve 6 is set on the outer wall of the wire column 5. When the outer sealing shell 8 is connected with the inner sealing shell 4 by thread, the elastic insulator 7 When squeezed, the compression sleeve 6 is driven to compress the circular base of the wire column 5 toward one end of the electrode, thereby pressing the wire column 5 against the electrode. After the two groups of outer sealing shells 8 are connected to the inner sealing shell 4, the anti-rotation pin 12 is stuck between the two groups of vertical grooves 11, which prevents the outer sealing shell 8 from rotating and ensures safety during use. When installing the outer sealing shell 8, a group of outer sealing shells 8 with a marking ring 10 is installed on the end of the inner sealing shell 4 with the marking ring 10. The negative electrode can be easily identified by the blue marking ring 10.
