The diode leads are the metal conductors that connect the diode to the chip and are an important component of the diode.

[0003] However, the usual diode assembly and disassembly operations are quite inconvenient, and loosening is very likely to occur during long-term use. In particular, the lack of measures to fix the diode leads makes it easy for the diode leads to come loose, affecting the stability of the connection.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6 This utility model provides a technical solution: a TVS diode for preventing lead wire loosening, including a carrier plate 1, a mounting base 2, a diode body 3, a fixing clamp 4, a positioning mechanism 5, a fixing post 6, a fixing plate 7, a positioning plate 8, a positioning cap 9, a lead wire holder 10, a lead wire clamp 11, a side plate 12, a movable plate 13, a pull ring 14, a spring 15, a fixing pin 16, and an ear plate 17.

[0030] When using a TVS diode that prevents lead loosening, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a mounting base 2 is fixedly connected to the middle of the upper end of the carrier plate 1. When installing the diode body 3, the diode body 3 is first directly snapped onto the mounting base 2, and then the fixing clamp 4 is snapped onto the diode body 3. The fixing clamp 4 is attached to the upper end of the diode body 3. The fixing clamp 4 can press and fix the diode body 3, so that the diode body 3 can be installed stably and conveniently. Combined with the setting of the positioning mechanism 5, the positioning mechanism 5 is symmetrically arranged on the left and right sides of the fixing clamp 4. The positioning mechanism 5 includes a fixing post 6 fixedly connected to the left and right sides of the upper end of the fixing clamp 4, a fixing plate 7 for limiting the position, a positioning plate 8 fixedly connected to the lower end of the fixing plate 7, and a positioning cap 9 for locking.

[0031] The fixing plate 7 and the fixing post 6 are connected by a slot, and the fixing plate 7 and the fixing clamp 4 are fitted together. A positioning plate 8 is fixedly connected to the lower end of the fixing plate 7. The fixing plate 7 drives the positioning plate 8 to be inserted into the left and right ends of the mounting base 2. Then, by rotating the positioning cap 9, which is threaded onto the outer surface of the fixing post 6, the positioning cap 9 is fitted to the upper end of the fixing plate 7. The positioning cap 9 prevents the fixing plate 7 from loosening from the fixing post 6, thus facilitating the fixing of the clamp 4 and the mounting base 2 and improving the tightness of the diode body 3 installation. Furthermore, lead seats 10 are fixedly connected to the front and rear sides of the upper end of the carrier plate 1. During the installation process, the diode body 3 moves the lead wire to the upper end of the lead seat 10, combined with… Figure 5 and Figure 6 As shown, by pulling the pull ring 14, the pull ring 14 causes the movable plate 13 to slide between the side plate 12, the movable plate 13 compresses the spring 15, causing the spring 15 to undergo elastic deformation, at which time the movable plate 13 drives the fixed pin 16 to extend and retract.

[0032] Then, the lead clamp 11 is attached to the upper end of the lead holder 10. The lead clamp 11 presses and fixes the lead wire, thereby preventing the lead wire from loosening and improving the stability of the lead wire during use. At this time, the fixing pin 16 is aligned with the ear plate 17, and then the pull ring 14 is released directly. At this time, the spring 15 returns to its elastic deformation, causing the movable plate 13 to slide between the side plate 12, so that the movable plate 13 drives the fixing pin 16 to engage with the ear plate 17, thereby facilitating the limitation between the lead holder 10 and the lead clamp 11, which can achieve a good fixing effect on the lead wire.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
